This disclosure relates to the technical field of infant and toddler products, and more particularly to an infant or toddler carrier or child carrier capable of adjusting the leg support of an infant or toddler. This disclosure also relates to an infant or toddler carrier or child carrier having a seat height adjustment structure.

A baby carrier allows caregivers to keep their hands free while holding their infant, while maintaining close contact with the child. The design of a baby carrier should not only be ergonomic to reduce the burden on the user, but also provide support for the baby's hips, legs, waist, neck, and head, avoiding bending and unnecessary pressure to ensure comfort and safety.

Infants of different ages, different age groups of the same infant, and different holding methods all require different seating spaces, particularly different seating widths. Most baby carriers currently on the market provide a fixed seating space, making it difficult to adjust the width of the seat in the horizontal direction. This, in turn, makes it difficult to adjust the seating width, resulting in poor comfort for the baby's hips and legs. Some baby carriers, while capable of adjusting the seat width, are often complex and require manual adjustment, making them inconvenient to use.

The first aspect of this application

The present disclosure provides a baby carrier with an adjustable seat width, which has a simple structure and is easy to use.

According to an embodiment of the present disclosure, the infant carrier includes a waist belt, a child support, shoulder straps, and a leg support. One side of the child support is connected to the waist belt, and the portion of the child support proximal to the waist belt forms a hip support. The shoulder straps are connected to the side of the child support distal to the waist belt. The leg support is connected to the hip support and can be switched between an extended state and a retracted state. The hip support and the leg support form a seat for supporting an infant. When the leg support is in an extended position, the outer edges of the leg support extend away from the hip support in the lateral width of the child support to increase the width of the seat. When the leg support is in a retracted position, the outer edges of the leg support extend toward the hip support in the lateral width of the child support to reduce the width of the seat.

The baby carrier of this embodiment automatically switches between an extended and retracted position of the leg support under the baby's own weight, eliminating the need for manual adjustment of the seat width. This provides an appropriate seating width for babies of different sizes and in different seating orientations, providing excellent support for the baby's hips and legs while enhancing their comfort.

(1) The first aspect of this application

According to a first embodiment of the present disclosure, a baby carrier is provided. As shown in Figures 1 and 2, the baby carrier includes a waist belt A1, shoulder belts A2, and a child support member A3 connected to the waist belt A1 and the shoulder belt A2, respectively. The shoulder belt A2 is arranged roughly along the longitudinal depth direction of the child support member A3. One side of the child support member A3 is connected to the waist belt A1, and the side of the child support member A3 away from the waist belt A1 is detachably or non-detachably connected to the shoulder belt A2. That is, the upper side of the child support member A3 is connected to the shoulder belt A2, and the lower side of the child support member A3 is connected to the waist belt A1. In this embodiment, the upper side of the child support member A3 is detachably connected to the shoulder strap A2 via a connector (e.g., a buckle). In other embodiments, the child support member A3 and the shoulder strap A2 may be fixedly connected. This application does not limit the specific connection method between the child support member A3 and the shoulder strap A2. Referring to Figures 1 and 2, the child support member A3 includes a hip support portion A31 and a trunk support portion A32 that are connected to each other. In this embodiment, the child support member A3 is integrally formed. The hip support A31 is connected to the waist belt A1 on the side away from the trunk support A32, and the trunk support A32 is connected to the shoulder belt A2 on the side away from the hip support A31.

It is worth noting that the depth direction of the child support A3 described in the preceding and following paragraphs specifically refers to the direction from the side where the child support A3 is connected to the waist belt A1 to the side where the child support A3 is connected to the shoulder straps A2, i.e., from the lower side to the upper side or vice versa, of the child support A3.

Furthermore, as shown in Figures 1, 2, and 5, the baby carrier also includes a connecting portion A4 connected to the waist belt A1 and the shoulder straps A2. A storage space for accommodating infants is formed between the connecting portion A4 and the child support member A3. The connecting portion A4 includes a first connecting portion A41 and a second connecting portion A42. The first connecting portion A41 is a generally rectangular piece of cloth. There are two first connecting portions A41, which are spaced apart and connected to the corresponding shoulder straps A2. One side of the second connecting portion A42 is connected to the two second connecting portions A42, respectively, and the other side of the second connecting portion A42 is connected to the two shoulder straps A2, respectively. In one embodiment, the connecting portion A4 can be a one-piece fabric piece, with one side of the connecting portion A4 connected to the waist belt A1 and the other side of the connecting portion A4 connected to the shoulder straps A2. In another embodiment, the infant carrier may not include the connecting portion A4, with the shoulder straps A2 extending directly to and connecting to the waist belt A1.

Referring to Figures 1, 2, and 5, the side of the trunk support A32 distal from the hip support A31—that is, the side of the child support A3 distal from the waist belt A1—is detachably connected to the shoulder belt A2, making it easier for infants to enter and exit the storage space. During use, the waist belt A1 is first secured to the caregiver's waist, and the shoulder belts A2 are hung from the caregiver's shoulders. The connecting portion A4 then rests against the caregiver's torso. The caregiver can then pick up the infant and connect the child support A3 distal from the waist belt A1 to the shoulder belt A2, placing the infant within the storage space. In this embodiment, the baby carrier forms a storage space through the connecting portion A4 and the child support member A3, providing better wrapping and protection for the baby.

Furthermore, as shown in Figures 1 and 2, the infant carrier also includes leg supports A51 (arranged on the left and right sides relative to the hip support A31). The leg supports A51 are connected to the hip support A31 and can be switched between an expanded state and a retracted state. The hip support A31 and the leg supports A51 form a seat A6 for supporting an infant. When the leg supports A51 are in the expanded state, at least a portion of the leg supports A51 (in this embodiment, the middle portion of the leg supports A51) is generally away from the hip support A31 in the lateral width direction of the child support A3 to increase the width of the seat A6. When the leg support A51 is in the retracted position, at least a portion of the leg support A51 (in this embodiment, the middle portion of the leg support A51) is generally aligned with the hip support A31 in the transverse direction of the child support A3, thereby reducing the width of the seat A6.

It is worth noting that the horizontal width of the child support member A3 described in the previous paragraph and below specifically refers to the direction from the left side to the right side or the right side to the left side of the child support member A3.

In this embodiment, as shown in Figures 1 and 2 , the leg support A51 is elastically connected to the hip support A31 and can be switched between an extended state and a retracted state. Specifically, an elastic member A7 is connected between the hip support A31 and the leg support A51. The elastic member A7 can be switched between an extended state and a non-extended state, allowing the leg support A51 to switch between an extended state and a retracted state, thereby adjusting the width of the seat A6 in the horizontal direction, that is, adjusting the width for the infant to sit. Among them, the elasticity of the elastic part A7 is greater than the elasticity of the buttocks support part A31 and the leg support part A51, so that when the seat part A6 is subjected to external force, the elastic part A7, the buttocks support part A31 and the leg support part A51 are all stretched, and the elastic deformation of the elastic part A7 is greater than the elastic deformation of the buttocks support part A31 and the leg support part A51. It should be noted that the extended state of the elastic member A7 refers to a state in which the elastic member A7 is stretched under the action of an external force (e.g., the weight of an infant); the non-extended state of the elastic member A7 includes a naturally extended state in which the elastic member A7 is free of external force or is subjected to an inward compressive force, or a folded state in which the elastic member A7 is at least partially folded.

The baby carrier of this embodiment automatically switches between an extended and retracted position of the leg support A51 under the baby's own weight, eliminating the need to manually adjust the width of the seat A6. This provides an appropriate seating width for the baby, effectively meeting the seating width requirements of babies of different sizes and in different seating orientations. It provides excellent support for the baby's hips and legs, while also enhancing seating comfort. The baby carrier of this embodiment has a simple structure and is easy to use. In this embodiment, the elastic member A7 better wraps around the baby's hips and legs, further increasing the support provided by the seat A6 and improving seating comfort.

Furthermore, the elastic member A7 can switch between an extended state and a non-extended state depending on the infant's body shape or the infant's seating orientation. Referring to Figure 1 , when the infant is seated in the upright position, the required sitting width is smaller, the downward curvature of the seat portion A6 is smaller, and the pulling force F generated by the infant's weight on the sides of the elastic member A7 connecting the leg support portion A51 and the hip elastic member A7 is smaller (or because the elastic member A7 is still folded, the sides of the elastic member A7 are not yet subjected to the pulling force F), causing the elastic member A7 to be generally in the non-extended state. Referring to Figure 2, when an infant sits facing away from the child, they require more space to sit, and the seat A6 curves downward more sharply. The infant's weight exerts a greater pulling force F on the sides of the elastic member A7 connecting the leg support A51 and the hip elastic member A7, causing the elastic member A7 to be stretched to its extended position.

Similarly, when the infant is smaller, the required sitting width is smaller, and the tension F generated by the infant's weight on the sides of the elastic member A7 connecting the leg support A51 and the hip elastic member A7 is smaller (or because the elastic member A7 is still folded, the sides of the elastic member A7 are not yet subjected to the tension F), causing the elastic member A7 to be generally in a non-extended state. When the infant is larger, the tension F generated by the infant's weight on the sides of the elastic member A7 connecting the leg support A51 and the hip elastic member A7 is larger, causing the elastic member A7 to be stretched to an extended state.

Furthermore, as shown in Figures 1 and 2, the two outer edges of the hip support A31 in the transverse direction are curved edges that are recessed toward the center of the child support A3. This facilitates the placement of the leg support A51 and also allows the seat A6 to be reduced in width when the infant is seated with their back to the caregiver or when the infant is smaller, thereby preventing constriction on the infant's legs.

As shown in Figures 1 and 2, a leg support A51 is provided on both sides of the hip support A31 in the transverse direction. Specifically, the two leg supports A51 are provided on either side of the hip support's outer edge A311. The transverse distance between the outer edges A513 of the two leg supports defines the width of the seat A6. The outer edge A513 of the leg support refers to the side of the leg support A51 that is furthest from the hip support A31 in the transverse direction of the child support A3. When the leg supports A51 are in the extended position, the middle portions of the outer edges A513 of the two leg supports are relatively far away from the hip support A31. When the leg supports A51 are in the retracted position, the middle portions of the outer edges A513 of the two leg supports are relatively close to the hip support A31. Accordingly, two elastic members A7 are provided, or two groups of two. Each leg support A51 is connected to the hip support A31 by an elastic member A7. For ease of description, the following description uses the leg support A51 and elastic member A7 located on one side of the hip support A31 as an example.

Specifically, as shown in Figures 4, 6, and 7, the leg support A51 can have a multi-layer structure. A padding layer or filler is provided within the leg support A51, ensuring that the leg support A51 provides better support for the infant while also making the ride more comfortable. The padding layer or filler includes at least one of a hard sheet and an elastic filler. Similarly, the hip support A31 can also have a multi-layer structure. A padding layer or filler is provided within the hip support A31, ensuring that the hip support A31 provides better support for the infant while also making the ride more comfortable.

The elastic member A7, connected between the leg support A51 and the hip support A31, can be a single-layer structure, thinner than the leg support A51 and hip support A31, to enhance infant comfort. The elastic member A7 comprises an elastic sheet made of flexible elastic fabric, enabling it to switch between extended and non-extended positions. In other embodiments, the elastic member A7 comprises at least one elastic belt made of flexible elastic fabric, or a combination of at least one elastic belt and at least one elastic sheet.

As shown in Figures 3 to 6 , one end of the leg support A51 serves as a first connection end A511 and is connected to the child support A3, while the other end of the leg support A51 serves as a second connection end A512 and is connected to the child support A3 or the waist belt A1. Specifically, the first connection end A511 can be connected to the outer edge of the hip support A31 near the trunk support A32, and the second connection end A512 can be connected to the side of the waist belt A1 near the hip support A31. In other words, the first connection end A511 and the second connection end A512 are generally arranged along the depth direction, with the first connection end A511 located on the side of the second connection end A512 that is farther from the waist belt A1. The portion of the leg support A51 between the first connection end A511 and the second connection end A512 is not directly connected to the hip support A31, allowing at least a portion of the leg support A51 (in this embodiment, the middle portion of the leg support A51) to move away from or closer to the seat A6 in the lateral direction of the child support A3, thereby adjusting the width of the seat A6. In this embodiment, the first connection end A511 and the second connection end A512 of the leg support A51 are both fixedly or detachably connected to the child support A3 or the waist belt A1, so the first connection end A511 and the second connection end A512 of the leg support A51 are fixed relative to the child support A3. Therefore, the middle portion of the leg support A51 described in this paragraph and above specifically refers to the portion of the leg support A51 located between the first connection end A511 and the second connection end A512. Of course, in other embodiments, the other end of the leg support A51 may also be connected to the hip support A31 near the waist belt A1. Alternatively, the other end of the leg support A51 may be connected to both the hip support A31 and the waist belt A1. This application does not impose any restrictions on the specific connection location of the leg support A51, as long as the portion of the leg support A51 located between the first connection end A511 and the second connection end A512 can be relatively far from or close to the seat A6 in the width direction of the child support A3.

3 to 6 , the leg support A51 has a linear first connection location A514 that is offset from the outer edge A513 of the leg support A51. An elastic member A7, such as an elastic sheet, is connected to the first connection location A514 on one side in the transverse direction of the child support A3. Specifically, one side in the transverse direction of the elastic member A7 is connected to the back side of the leg support A51 (i.e., the side of the leg support A51 facing the infant). The elastic member A7 and the leg support A51 can be connected by, for example, sewing. The hip support A31 has a linear second connection location A312. The second connection position A312 is located at or near the outer edge of the hip support A31 opposite to the first connection position A514. The second connection position A312 is spaced apart from the first connection position A514. The other side of the elastic member A7 (e.g., an elastic sheet) in the transverse direction of the child support A3 is connected to the second connection position A312. Specifically, the other side of the elastic member A7 in the transverse direction of the child support A3 can be connected to the back side of the hip support A31 (i.e., the side of the hip support A31 facing the infant), or it can be connected to the inside of the hip support A31, i.e., connected between the multi-layer structure of the hip support A31. The elastic member A7 and the hip support A31 can be connected by, for example, sewing. In embodiments where the elastic member A7 comprises multiple elastic bands, one end of each elastic band can be connected to the back of the leg support A51, and the other end can be connected to the inside or back of the hip support A31.

Referring to Figures 4, 6, and 7, the portion of the leg support A51 near the first connection end A511, the upper side of the elastic member A7, and the outer edge A311 of the hip support together enclose a first opening A81. This increases the elastic clearance of the leg support A51. Correspondingly, the portion of the leg support A51 near the second connection end A512, the lower side of the elastic member A7, and the outer edge A311 of the hip support together enclose a second opening A82. This increases the elastic clearance of the leg support A51. Of course, in other embodiments, both the first opening A81 and the second opening A82 may be omitted, or only the first opening A81 or the second opening A82 may be provided.

In one embodiment, as shown in Figures 1 to 4, the seat portion A6 further includes a wing portion A52, which is connected to the leg support portion A51 on one side in the transverse direction of the child support member A3, and extends toward the hip support portion A31 on the other side in the transverse direction of the child support member A3. Specifically, the wing portion A52 is connected to the first connection position A514 of the leg support portion A51 and at least partially covers the elastic member A7, the first opening A81 or the second opening A82, so that the baby carrier is more beautiful when viewed from the front (i.e., the side facing away from the baby). In addition, the wing portion A52 extends in the transverse direction toward the hip support portion A31, increasing the support area at the first opening A81 and the second opening A82, making the baby's leg support more comfortable. In this embodiment, the wing portion A52 is integrally formed with the leg support portion A51. In another embodiment, the wing portion A52 can be connected to the leg support portion A51 by, for example, sewing. Continuing with Figures 1 to 4 , two wing portions A52 are provided, and the two wing portions A52 are connected to the corresponding first connection locations A514 in the two leg support portions A51, respectively.

In other embodiments (not shown), the wing portion A52 may also be connected to the hip support portion A31 on one side of the child support portion A3 in the transverse direction, at least partially covering the elastic member A7, the first opening A81, and the second opening A82, thereby enhancing the appearance of the baby carrier when viewed from the front. In this embodiment, the wing portion A52 is integrally formed with the hip support portion A31. In other embodiments, the wing portion A52 may be connected to the hip support portion A31 by, for example, sewing.

The operating principle of the baby carrier in this embodiment is as follows: Referring to FIG2 , when the sitting width required by the baby's buttocks and legs is large, for example, when the baby is sitting with its back facing (i.e., facing the caregiver), the downward curvature of the seat A6 is large, and the pulling force F generated by the baby's weight on the two sides connecting the elastic member A7 with the leg support A51 and the buttocks elastic member A7 is large, and the elastic member A7 is Component A7 is stretched to its extended position to better wrap the baby's legs and hips. The leg supports A51 are now extended, with the center portions of the two leg supports A51 relatively far from the hip support A31. This increases the width of the base A6, ensuring that the baby's legs form an M-shaped structure rather than hanging down, providing good support for the baby's thighs. Referring to FIG1 , when the sitting width required by the infant's buttocks and legs is smaller, for example, when the infant is sitting with its back facing (i.e., facing the caregiver), the downward curvature of the seat portion A6 is smaller, and the pulling force F generated by the infant's weight on the two sides connecting the elastic member A7 with the leg support portion A51 and the buttocks elastic member A7 is smaller (or because the elastic member A7 is still folded). (In the non-extended position, the sides of the elastic member A7 are not yet subjected to the tensile force F.) The elastic member A7 is in a non-extended position, causing the leg supports A51 to be retracted. The middle portions of the two leg supports A51 are relatively close to the hip support A31, and the width of the corresponding seat portion A6 is reduced. This prevents the infant's legs from being constricted, making the ride more comfortable.

Of course, the width adjustment of the seat A6 is not limited to the situations where the infant sits rear-facing or forward-facing. For example, under the same riding mode, for infants of different sizes, larger infants have larger hips and legs, so they require a correspondingly larger seat A6 width. Moreover, since larger infants have a greater weight, when they sit, the elastic member A7 can be extended and partially wrap the infant's legs and hips, so that the leg support portion A51 is in an expanded state, thereby providing the infant with a larger seat A6 width, ensuring that the baby's legs are in an M-shaped structure instead of hanging directly, and providing good support for the infant's thighs. Similarly, smaller infants require a correspondingly smaller seat A6 width due to their smaller hips and legs. Furthermore, smaller infants, due to their lower weight, can keep the elastic member A7 in its non-extended position while sitting, allowing the leg support A51 to be retracted. The center of the leg support A51 is relatively close to the hip support A31, reducing the width of the seat A6 and preventing constriction on the infant's legs, thereby providing a more comfortable ride.

Figures 8 to 14 illustrate a baby carrier according to a second embodiment of the present application. This embodiment differs from the aforementioned embodiments in at least the following ways: In this embodiment, the seat A6 is not provided with an elastic member A7. An adjustment opening A83 is formed between the first connection end A511 and the second connection end A512 of the leg support A51, spaced apart from the hip support A31. The adjustment opening A83 is switchable between an open state (see Figures 9, 13, and 17) and a closed state (see Figures 8, 10, and 12), allowing the leg support A51 to switch between the extended and closed states. This allows the center portion of the leg support A51 to move away from or closer to the seat A6, thereby adjusting the width of the seat A6.

In this embodiment, referring to Figures 10 and 12 , when the infant carrier is naturally flat, the adjustment opening A83 (see Figure 11 ) is obscured by the wing portion A52. Referring to Figure 8 , when the infant is seated in the forward position, the required seating width for the infant's hips and legs is smaller, and the leg support A51 is retracted, with the middle portion of the leg support A51 relatively close to the hip support A31. At this time, the adjustment opening A83 (not shown in Figure 8 ) is obscured by the leg support A51 or the wing portion A52. Referring to Figures 9 and 17 , when an infant sits facing away from the child, the required seating width for the infant's buttocks and legs is greater. The leg support A51 is in the unfolded position, with the center of the leg support A51 relatively far from the buttock support A31. At this time, the adjustment opening A83 may be exposed (see Figure 9 ) or may be obscured by the leg support A51 or the wing portion A52 (see Figure 14 ). This application is not limited to this. The arrangement of other components in this embodiment can refer to the previous embodiment and will not be further described here.

Figures 15 to 18 illustrate a baby carrier according to a third embodiment of the present application. This embodiment differs from the first embodiment described above in at least the following ways: In this embodiment, as shown in Figures 15 and 16 , the seat portion A6 is not provided with an elastic member A7. The leg support portion A51 has a generally trapezoidal structure, comprising a first side A515 and a second side A516 that are opposed and substantially parallel, and a third side A517 and a fourth side A518 that are opposed and angled. The first side A515 forms the outer edge A513 of the leg support. The second side A516 is shorter than the first side A515 and extends toward the middle of the width of the child support A3. The third side A517 and the fourth side A518 are connected between the first side A515 and the second side A516, respectively, with the third side A517 positioned further away from the waist belt A1 than the fourth side A518.

As shown in Figure 16 , the first side A515 of the leg support A51 has a first connection end A511 and a second connection end A512 at its two ends. Similar to the first embodiment, the first connection end A511 is connected to the child support A3, and the second connection end A512 is connected to the child support A3 or the waist belt A1. The first connection end A511 is located on the side of the second connection end A512 that is away from the waist belt A1. The child support A3 is connected to the first connection end A511 at the third connection point A313. The second side A516 of the leg support A51 is connected to the fourth connection point A314 of the child support A3. Specifically, the fourth connection point A314 is linear and located on the back of the child support A3 (i.e., the side of the child support A3 facing the infant). The fourth connection point A314 is located on the hip support A31, offset from the outer edge A311 of the hip support. In this embodiment, the second side A516 of the leg support A51 is sewn to the fourth connection point A314 of the child support A3. As shown in Figure 17, the seams of the second side A516 and the fourth connection point A314 are not visible from the front of the child support A3 (i.e., the side of the child support A3 facing away from the infant), making the child support A3 appear more aesthetically pleasing and neat when in use.

As shown in FIG16 , the length of the leg support A51 from the first side A515 to the second side A516 is greater than the length from the third connection location A313 to the fourth connection location A314 of the child support A3, allowing the leg support A51 to switch between an extended state and a retracted state. When the leg support A51 is in the extended state, the first side A515 of the leg support A51, i.e., the outer edge A513 of the leg support, is farther away from the hip support A31 in the width direction of the child support A3, thereby increasing the width of the seat A6. When the leg support A51 is in the retracted position, the first side A515 of the leg support A51, i.e., the outer edge A513 of the leg support, leans toward the hip support A31 in the lateral direction of the child support A3, thereby reducing the width of the seat A6.

It should be understood that the length of the leg support A51 from the first side A515 to the second side A516 referred to herein specifically refers to the actual length of the fabric forming the leg support A51 between the first side A515 and the second side A516. Similarly, the length of the child support A3 from the third connection location A313 to the fourth connection location A314 refers to the actual length of the fabric forming the child support A3 between the third connection location A313 and the fourth connection location A314. In this embodiment, the leg support A51 includes a filling portion A5191 and a deforming portion A5192, which are adjacently arranged along the width of the child support A3. Specifically, the leg support A51 has a partition A5193 between the first side A515 and the second side A516. The portion of the leg support A51 from the first side A515 to the partition A5193 forms the filling portion A5191, while the portion of the leg support A511 from the partition A5193 to the second side A516 forms the deformable portion A5192. Specifically, the filling portion A5191 is a multi-layered structure with a padding layer or filler inside to provide adequate support for infants' legs. The deformable portion A5192 is made of ordinary fabric. The partition A5193 is a dividing seam, separating the filling portion A5191 and the deformable portion A5192.

The deformable portion A5192 is switchable between a curled state and an extended state, thereby enabling the deformable portion A5192 to switch between an expanded state and a retracted state. When the infant carrier is free of external force or subjected to inward compression, the deformable portion A5192 is in its naturally curled state. The first side A515 of the leg support portion A51, i.e., the outer edge A513 of the leg support portion, leans toward the hip support portion A31 in the lateral direction of the child support A3, thereby reducing the width of the seat portion A6. When the infant carrier is subjected to external forces, such as when a child is seated in the carrier, the deformable portion A5192 is properly stretched and extended. The first side A515 of the leg support A51, i.e., the outer edge A513 of the leg support, moves away from the hip support A31 in the lateral width of the child support A3, thereby increasing the width of the seat A6.

Furthermore, as shown in Figure 16, assuming the length of the first side A515 of the leg support A51 is L1 and the length of the second side A516 of the leg support A51 is L2, then L1 and L2 satisfy the following relationship: L2/L1=1/3~1/2.

This design ensures that the second side A516 of the leg support A51 has an appropriate length. Since the leg support A51 is used to connect to the fourth linear connection point A314 on the child support A3, the connection strength between the leg support A51 and the child support A3 and the support stability of the leg support A51 can be ensured.

Furthermore, as shown in Figure 16 , similar to the first embodiment, a leg support portion A51 is provided on both sides of the hip support portion A31 in the transverse direction. The distance between the second sides A516 of the two leg supports A51 is W1, and the distance between the first sides A515 of the two leg supports A51 is W2. W1 and W2 satisfy the following relationship: W1/W2 = 1/3 to 2/3.

This arrangement ensures that the lateral dimensions of the leg support A51 and the entire seat A6 remain within a reasonable range, thereby ensuring the comfort and flexibility of the seat A6 in this direction.

Furthermore, as shown in Figures 17 and 18 , a first opening A81 is formed between the third side A517 and the child support A3, and a second opening A82 is formed between the fourth side A518 and the child support A3. The infant carrier also includes a wing portion A52, one side of which is connected to the fifth connection location A315 of the hip support A31. The side of the wing portion A52, which is farther from the hip support A31 in the width direction, forms an active side A521. The active side A521 is spaced apart from the leg support A51 to form a third opening A84. The third opening A84 is connected to both the first opening A81 and the second opening A82, allowing the first opening A81 and the second opening A82 to be exposed. The wing portion A52 at least partially covers the first opening A81 or the second opening A82 to maintain the neat and aesthetic appearance of the child support A3, while also providing a certain degree of support. In this embodiment, the fifth connection point A315 and the fourth connection point A314 are actually located at the same location on the back and front of the child support A3, respectively. In this embodiment, as shown in Figures 17 and 18, when the infant carrier is naturally flat, the first opening A81 and the second opening A82 are obscured by the wing portion A52. When an infant sits in the forward position, the required seating width for the infant's hips and legs is smaller, and the leg support A51 is in a retracted position. Specifically, because the length from the first side A515 to the second side A516 is greater than the length from the third connection point A313 to the fourth connection point A314 of the child support A3, the leg support A51 is curled up, bringing the middle portion of the leg support A51 relatively close to the hip support A31. At this time, the first and second openings A82 are obscured by the wing portion A52. When an infant sits facing away from the child, the infant's buttocks and legs require a wider seating angle, and the leg support A51 is in the expanded state. Specifically, the leg support A51 is stretched out by the infant's buttocks and legs, causing the center of the leg support A51 to be relatively far away from the buttock support A31. At this point, the first opening A81 and the second opening A82 may be exposed through the third opening A84 or at least partially obscured by the wing A52.

(2) The second aspect of this application

Example 1

The first embodiment of the present disclosure provides a child carrier B1000. As shown in Figures 19 and 20, the child carrier B1000 includes a waist belt B120, a shoulder belt B110, and a carrying assembly B200 connected to the waist belt B120 and the shoulder belt B110, respectively. The shoulder belt B110 is arranged roughly along the longitudinal direction of the carrying assembly B200. One side of the carrying assembly B200 is connected to the waist belt B120, and the side of the carrying assembly B200 away from the waist belt B120 is detachably connected to the shoulder belt B110. In other words, the upper side of the carrying assembly B200 is connected to the shoulder belt B110, and the lower side of the carrying assembly B200 is connected to the waist belt B120. In this embodiment, the upper side of the carrying assembly B200 is detachably connected to the shoulder strap B110 via a connector (e.g., a buckle). In other embodiments, the carrying assembly B200 and the shoulder strap B110 may be fixedly connected. This application does not limit the specific connection method between the carrying assembly B200 and the shoulder strap B110. Referring to Figures 19 and 20, the carrying assembly B200 includes a hip support portion B210 and a trunk support portion B220 that are connected to each other. In this embodiment, the carrying assembly B200 is integrally formed. The side of the hip support B210 that is away from the trunk support B220 is connected to the waist belt B120, and the side of the trunk support B220 that is away from the hip support B210 is connected to the shoulder belt B110.

It is worth noting that the depth direction of the carrying assembly B200 described in the previous paragraph and below specifically refers to the direction from the side where the carrying assembly B200 is connected to the waist belt B120 to the side where the carrying assembly B200 is connected to the shoulder strap B110, that is, the direction from the lower side to the upper side or the upper side to the lower side of the carrying assembly B200.

Furthermore, as shown in Figures 19, 20 and 23, the child carrier B1000 also includes a connecting portion B4 connected to the waist belt B120 and the shoulder straps B110. A storage space for accommodating infants and young children is formed between the connecting portion B4 and the carrying assembly B200. The connecting portion B4 includes a first connecting portion B41 and a second connecting portion B42. The first connecting portion B41 is a generally rectangular piece of cloth. There are two first connecting portions B41, which are spaced apart and connected to the corresponding shoulder straps B110. One side of the second connecting portion B42 is connected to the two second connecting portions B42 respectively, and the other side of the second connecting portion B42 is connected to the two shoulder straps B110 respectively. In one embodiment, the connecting portion B4 can also be a one-piece fabric piece, with one side of the connecting portion B4 connected to the waist belt B120 and the other side of the connecting portion B4 connected to the shoulder strap B110. In another embodiment, the child carrier B1000 does not include the connecting portion B4, but instead the shoulder strap B110 extends to and connects to the waist belt B120.

19, 20, and 23, the side of the trunk support B220 distal from the hip support B210, i.e., the side of the carrying assembly B200 distal from the waist belt B120, is detachably connected to the shoulder belt B110, thereby facilitating the infant (also referred to as a child) to enter and exit the storage space. During use, the waist belt B120 is first secured to the caregiver's waist, and the shoulder belts B110 are hung from the caregiver's shoulders. The connecting portion B4 then rests against the caregiver's trunk, allowing the infant to be lifted up and the side of the carrying assembly B200 distal from the waist belt B120 to be connected to the shoulder belt B110, allowing the infant to sit within the storage space. In this embodiment, the child carrier B1000 forms a storage space through the connecting portion B4 and the carrying component B200, providing better wrapping and protection for infants.

Furthermore, as shown in Figures 19 and 20, the child carrier B1000 also includes leg supports B230 (located on the left and right sides relative to the hip support B210). The leg supports B230 are connected to the hip support B210 and can be switched between an expanded state and a retracted state. Specifically, the leg supports B230 have a first connection end B231 and a second connection end B232. The first connection end B231 is connected to the carrying component B200, and the second connection end B232 is connected to the waist belt B120 or the carrying component B200. In the depth direction, at least a portion of the leg supports B230 located between the first connection end B231 and the second connection end B232 is not connected to the hip support B210. The hip support B210 and the leg support B230 form a seat B6 for supporting an infant. When the leg support B230 is in the expanded state, at least a portion of the leg support B230 (in this embodiment, the middle portion of the leg support B230) is generally spaced apart from the hip support B210 across the width of the support assembly B200, thereby increasing the width of the seat B6. When the leg support B230 is in the retracted position, at least a portion of the leg support B230 (in this embodiment, the middle portion of the leg support B230) is generally aligned with the hip support B210 in the transverse direction of the support assembly B200, thereby reducing the width of the seat B6.

It is worth noting that the horizontal width of the carrier assembly B200 described in the previous paragraph and below specifically refers to the direction from the left side to the right side or the right side to the left side of the carrier assembly B200.

In this embodiment, as shown in Figures 19 and 20, the leg support B230 is elastically connected to the hip support B210 and can be switched between an expanded state and a retracted state. Specifically, an elastic member B7 is connected between the hip support B210 and the leg support B230. The elastic member B7 can be switched between an extended state and a non-extended state, allowing the leg support B230 to switch between an expanded state and a retracted state, thereby adjusting the width of the seat B6 in the lateral direction, that is, adjusting the sitting width of the infant. The elasticity of the elastic member B7 is greater than that of the hip support B210 and the leg support B230. Consequently, when the seat B6 is subjected to an external force, the elastic member B7, the hip support B210, and the leg support B230 are all stretched, with the elastic member B7 experiencing a greater elastic deformation than the hip support B210 and the leg support B230. It should be noted that the extended state of the elastic member B7 refers to a state in which the elastic member B7 is stretched under the action of an external force (e.g., the weight of an infant). The non-extended state of the elastic member B7 includes a naturally extended state in which the elastic member B7 is free of external force or is subjected to an inward compressive force, or a folded state in which the elastic member B7 is at least partially folded.

The child carrier B1000 of this embodiment automatically switches between an extended and retracted position of the leg support B230 under the child's weight, eliminating the need to manually adjust the width of the seat B6. This provides the appropriate sitting width for the child, effectively meeting the seating width requirements of infants of varying sizes and in different seating orientations. It provides excellent support for the child's hips and legs, while also enhancing seating comfort. The child carrier B1000 of this embodiment has a simple structure and is easy to use. In this embodiment, the elastic member B7 better wraps around the child's hips and legs, further increasing the support provided by the seat B6 and improving seating comfort.

Furthermore, the elastic member B7 can switch between an extended state and a non-extended state depending on the infant's body shape or the direction the infant is sitting. Referring to Figure 19 , when the infant is sitting in the upright position, the required sitting width is smaller, the downward curvature of the seat portion B6 is smaller, and the pulling force F generated by the infant's weight on the sides of the elastic member B7 connecting to the leg support portion B230 and the hip elastic member B7 is smaller (or because the elastic member B7 is still in a folded state, the sides of the elastic member B7 are not yet subjected to the pulling force F), causing the elastic member B7 to be generally in the non-extended state. Referring to Figure 20 , when an infant sits facing away from the child, the required sitting width is greater, and the downward curvature of the seat portion B6 is greater. The infant's weight exerts a greater pulling force F on both sides of the elastic member B7 connecting to the leg support portion B230 and the hip elastic member B7, causing the elastic member B7 to be stretched to its extended state.

Similarly, when the infant is smaller, the required sitting width is smaller, and the tension F exerted by the infant's weight on the sides of the elastic member B7 connecting to the leg support B230 and the hip elastic member B7 is smaller (or, because the elastic member B7 is still folded, the sides of the elastic member B7 are not yet subjected to the tension F), causing the elastic member B7 to be generally in a non-extended state. When the infant is larger, the tension F exerted by the infant's weight on the sides of the elastic member B7 connecting to the leg support B230 and the hip elastic member B7 is greater, causing the elastic member B7 to be stretched to an extended state.

Furthermore, as shown in Figures 19 and 20, the two outer edges B214 of the hip support B210 in the transverse direction are curved edges that are recessed toward the center of the support assembly B200. This facilitates the placement of the leg support B230 and also allows the seat B6 to be reduced in width when the infant is seated with their back to the caregiver or when the infant is smaller, thereby preventing constriction on the infant's legs.

As shown in Figures 19 and 20, a leg support B230 is provided on both sides of the hip support B210 in the transverse direction. Specifically, the two leg supports B230 are located on either side of the hip support's outer edge B214. The transverse distance between the outer edges B236 of the two leg supports defines the width of the seat B6. The outer edge B236 of the leg support refers to the side of the leg support B230 that is distal to the hip support B210 in the transverse direction of the support assembly B200. When the leg supports B230 are in the extended position, the middle portions of the outer edges B236 of the two leg supports are relatively far from the hip support B210. When the leg supports B230 are in the retracted position, the middle portions of the outer edges B236 of the two leg supports are relatively close to the hip support B210. Accordingly, two elastic members B7 are provided, or two groups of two. Each leg support B230 is connected to the hip support B210 by an elastic member B7. For ease of description, the following description uses the leg support B230 and elastic member B7 located on one side of the hip support B210 as an example.

Specifically, as shown in Figures 22, 24, and 25, the leg support B230 can have a multi-layer structure. A padding layer or filler is provided within the leg support B230, providing better support for the infant while also making the ride more comfortable. The padding layer or filler includes at least one of a hard sheet and an elastic filler. Similarly, the hip support B210 can also have a multi-layer structure. A padding layer or filler is provided within the hip support B210, providing better support for the infant while also making the ride more comfortable.

The elastic member B7 connecting the leg support B230 and the hip support B210 can be a single-layer structure, thinner than the leg support B230 and hip support B210, to enhance infant comfort. The elastic member B7 comprises an elastic sheet made of flexible elastic fabric, enabling it to switch between extended and non-extended positions. In other embodiments, the elastic member B7 comprises at least one elastic belt made of flexible elastic fabric, or a combination of at least one elastic belt and at least one elastic sheet.

As shown in Figures 21 to 24, one end of the leg support B230 serves as a first connection end B231 and is connected to the carrying assembly B200, while the other end of the leg support B230 serves as a second connection end B232 and is connected to the carrying assembly B200 or the waist belt B120. Specifically, the first connection end B231 can be connected to the outer edge of the hip support B210 near the trunk support B220, and the second connection end B232 can be connected to the side of the waist belt B120 near the hip support B210. In other words, the first connection end B231 and the second connection end B232 are generally distributed along the depth direction, with the first connection end B231 located on the side of the second connection end B232 that is farthest from the waist belt B120. The portion of the leg support B230 between the first connection end B231 and the second connection end B232 is not directly connected to the hip support B210, allowing at least a portion of the leg support B230 (in this embodiment, the middle portion of the leg support B230) to move away from or closer to the seat B6 in the lateral direction of the support assembly B200, thereby adjusting the width of the seat B6. In this embodiment, the first connection end B231 and the second connection end B232 of the leg support B230 are both fixedly or detachably connected to the support assembly B200 or the waist belt B120. Therefore, the first connection end B231 and the second connection end B232 of the leg support B230 are fixed relative to the support assembly B200. It is worth noting that the middle portion of the leg support B230 specifically refers to the portion of the leg support B230 located between the first connection end B231 and the second connection end B232. Of course, in other embodiments, the other end of the leg support B230 may also be connected to the hip support B210 near the waist belt B120. Alternatively, the other end of the leg support B230 may be connected to both the hip support B210 and the waist belt B120. This application does not impose any restrictions on the specific connection location of the leg support B230, as long as the portion of the leg support B230 located between the first connection end B231 and the second connection end B232 is relatively far from or close to the seat B6 in the transverse direction of the support assembly B200.

21 to 24 , the leg support B230 has a linear first connection location B237 that is offset from the outer edge B236 of the leg support. An elastic member B7, such as an elastic sheet, is connected to the first connection location B237 on one side in the transverse direction of the support assembly B200. Specifically, one side of the elastic member B7 in the transverse direction is connected to the back side of the leg support B230 (i.e., the side of the leg support B230 facing the infant). The elastic member B7 and the leg support B230 can be connected by, for example, sewing. The hip support B210 has a linear second connection location B215. The second connection position B215 is located at or near the outer edge of the hip support B210 opposite to the first connection position B237. The second connection position B215 is spaced apart from the first connection position B237. The other side of the elastic member B7 (e.g., an elastic sheet) in the transverse direction of the supporting assembly B200 is connected to the second connection position B215. Specifically, the other side of the elastic member B7 in the transverse direction of the supporting assembly B200 can be connected to the back side of the hip support B210 (i.e., the side of the hip support B210 facing the infant), or it can be connected to the inside of the hip support B210, i.e., connected between the multi-layer structure of the hip support B210. The elastic member B7 and the hip support B210 can be connected by, for example, sewing. In embodiments where the elastic member B7 comprises multiple elastic bands, one end of each elastic band can be connected to the back of the leg support B230, and the other end can be connected to the inside or back of the hip support B210.

Referring to Figures 22, 24, and 25, the portion of the leg support B230 near the first connection end B231, the upper side of the elastic member B7, and the outer edge B214 of the hip support together form a first opening B233. This increases the elastic clearance of the leg support B230. Correspondingly, the portion of the leg support B230 near the second connection end B232, the lower side of the elastic member B7, and the outer edge B214 of the hip support together form a second opening B234. This increases the elastic clearance of the leg support B230. Of course, in other embodiments, both the first and second openings B233, B234 may be omitted, or only the first or second opening B233, B234 may be provided.

In one embodiment, as shown in Figures 19 to 22, the seat portion B6 further includes a wing portion B52, which is connected to the leg support portion B230 on one side in the transverse direction of the supporting component B200, and extends to the hip support portion B210 on the other side in the transverse direction of the supporting component B200. Specifically, the wing portion B52 is connected to the first connection position B237 of the leg support portion B230 and at least partially covers the elastic member B7, the first opening B233, and the second opening B234. This makes the child carrier B1000 more aesthetically pleasing when viewed from the front (i.e., the side facing away from the infant). In addition, the wing portion B52 extends in the transverse direction toward the hip support portion B210, increasing the support area at the first opening B233 and the second opening B234, making the infant's leg support more comfortable. In this embodiment, the wing portion B52 is integrally formed with the leg support portion B230. In another embodiment, the wing portion B52 can be connected to the leg support portion B230 by, for example, sewing. Continuing with Figures 19 to 22 , the wing portion B52 is provided in pairs, each connected to a corresponding first connection point B237 in the two leg supports B230.

In other embodiments (not shown), the wing portion B52 may also be connected to the hip support portion B210 on one side of the carrier assembly B200 in the transverse direction, at least partially covering the elastic member B7, the first opening B233, and the second opening B234, thereby enhancing the appearance of the child carrier B1000 when viewed from the front. In this embodiment, the wing portion B52 is integrally formed with the hip support portion B210. In other embodiments, the wing portion B52 may be connected to the hip support portion B210 by, for example, sewing.

The operating principle of the child carrier B1000 in this embodiment is as follows: Referring to Figure 20, when the infant's hips and legs require a larger sitting width, for example, when the infant is sitting with their back facing (i.e., facing the caregiver), the downward curvature of the seat portion B6 is greater, and the weight of the infant creates a greater pulling force F on the sides of the elastic member B7 connecting the leg support portion B230 and the hip elastic member B7. , the elastic part B7 is stretched to an extended state to better wrap the baby's legs and buttocks. At this time, the leg support part B230 is in an expanded state, and the middle parts of the two leg support parts B230 are relatively far away from the buttocks support part B210, corresponding to the increase in the width of the seat part B6, thereby ensuring that the baby's legs are in an M-shaped structure instead of hanging directly, which can form good support for the baby's thighs. Referring to FIG19 , when the sitting width required by the infant's buttocks and legs is smaller, for example, when the infant is sitting with its back facing (i.e., facing the caregiver), the downward curvature of the seat portion B6 is smaller, and the pulling force F generated by the infant's weight on the two sides connecting the elastic member B7 with the leg support portion B230 and the buttocks elastic member B7 is smaller (or because the elastic member B7 is still folded). (In the non-extended position, the sides of the elastic member B7 are not yet subjected to the tensile force F.) The elastic member B7 is in a non-extended position, causing the leg supports B230 to be retracted. The middle portions of the two leg supports B230 are relatively close to the hip support B210, making the seat B6 narrower. This prevents constriction on the infant's legs and provides a more comfortable ride.

Of course, the width adjustment of the seat B6 is not limited to the situations where the infant sits facing backward or forward. For example, under the same riding mode, for infants of different sizes, larger infants have larger hips and legs, so they require a correspondingly larger width of the seat B6. Since larger infants have a heavier weight, when they sit, the elastic member B7 can be extended and partially wrap the infant's legs and hips, so that the leg support part B230 is in an expanded state, thereby providing the infant with a larger seat B6 width, ensuring that the baby's legs are in an M-shaped structure instead of hanging directly, and can provide good support for the infant's thighs. Similarly, smaller infants require a smaller seat B6 due to their smaller hips and legs. Furthermore, smaller infants, due to their lower weight, can keep the elastic member B7 in its non-extended position while sitting, allowing the leg support B230 to be retracted. The center of the leg support B230 is relatively close to the hip support B210, making the seat B6 narrower and preventing constriction on the infant's legs, thus providing a more comfortable ride.

Example 2

Figures 26 to 32 illustrate a child carrier B1000 according to a second embodiment of the present disclosure. This embodiment differs from the first embodiment in at least the following ways: The seat portion B6 is not equipped with an elastic member B7. An adjustment opening B235 is formed between the first and second connection ends B231 and B232 of the leg support portion B230 and the hip support portion B210. The adjustment opening B235 can be switched between an open state (see Figures 27, 31, and 32) and a closed state (see Figures 26, 28, and 30), allowing the leg support B230 to switch between an expanded state and a retracted state. This allows the center portion of the leg support B230 to move away from or closer to the seat B6, thereby adjusting the width of the seat B6.

In this embodiment, referring to Figures 28 and 30 , when the child carrier B1000 is naturally flat, the adjustment opening B235 (see Figure 29 ) is obscured by the wing portion B52. Referring to Figure 26 , when the infant is seated in the forward position, the required sitting width for the infant's hips and legs is smaller, and the leg support B230 is in a retracted position, with the middle portion of the leg support B230 relatively close to the hip support B210. At this time, the adjustment opening B235 (not shown in Figure 26 ) is obscured by the leg support B230 or the wing portion B52. Referring to Figures 27 and 35 , when an infant sits facing away from the child, the infant's hips and legs require a larger seating width. The leg support B230 is in the unfolded position, with the center of the leg support B230 relatively far from the hip support B210. At this time, the adjustment opening B235 may be exposed (see Figure 27 ) or may be obscured by the leg support B230 or the wing portion B52 (see Figure 32 ). This application is not limited to this. The arrangement of other components in this embodiment can refer to the previous embodiment and will not be further described here.

Example 3

The third embodiment of the present disclosure provides a child carrier B1000. As shown in Figure 33, the child carrier B1000 includes a waist belt B120, a shoulder belt B110, a carrying assembly B200 connected to the waist belt B120 and the shoulder belt B110, and a leg support B230 connected to the carrying assembly B200. The shoulder belt B110 is arranged roughly along the longitudinal direction of the carrying assembly B200. One side of the carrying assembly B200 is connected to the waist belt B120, and the side of the carrying assembly B200 away from the waist belt B120 is detachably connected to the shoulder belt B110. That is, the upper side of the carrying assembly B200 is connected to the shoulder belt B110, and the lower side of the carrying assembly B200 is connected to the waist belt B120. The portion of the support assembly B200 near the waist belt B120 forms the hip support B210, while the upper side of the support assembly B200 forms the trunk support B220. The leg support B230 is connected to the hip support B210 and, together with the leg support B230, forms the seat B6 for supporting an infant or young child. The leg support B230 is switchable between an extended state and a retracted state. When in the extended state, the leg support B230 is positioned farther from the hip support B210 across the width of the support assembly B200, allowing the seat B6 to have a greater width. When the leg support B230 is in the retracted position, it leans against the hip support B210 in the lateral width of the support assembly B200, resulting in a smaller width for the seat B6. It should be understood that the larger width and smaller width herein may be referred to as a first width and a second width, respectively, with the second width being smaller than the first width.

This embodiment differs from the child carrier B1000 in the aforementioned embodiment in at least the following ways.

As shown in Figures 33 and 34 , the first connection end B231 of the leg support B230 is connected to the support assembly B200, while the second connection end B232 of the leg support B230 is connected to the support assembly B200 or the waist belt B120. In the depth direction, at least a portion of the leg support B230 between the first connection end B231 and the second connection end B232 is not connected to the hip support B210. In this embodiment, there are two leg supports B230, but this is not a limitation. The two leg supports B230 are located on the left and right sides of the hip support B210, respectively. Referring to Figures 33 and 34 , the leg support B230 includes a first leg support B230e located to the left of the hip support B210 and a second leg support B230f located to the right of the hip support B210. Referring to Figure 34 , in this embodiment, the portion of the leg support B230 between the first connection end B231 and the second connection end B232 is not directly connected to the hip support B210. This allows at least a portion of the leg support B230 (in this embodiment, the middle portion of the leg support B230) to be spaced apart from the hip support B210, forming an adjustment opening B235. Specifically, in this embodiment, the leg support B230 is connected to the hip support B210 at its approximately middle portion in the longitudinal direction via an elastic member B7, which at least partially covers the adjustment opening B235. The elastic member B7 is switchable between an extended state and a non-extended state, allowing the leg support B230 to expand or contract relative to the hip support B210 (i.e., allowing the edge line 236 of the leg support B230 to move away from or closer to the hip support B210). More specifically, referring to Figure 33, the elastic member B7 partially covers the adjustment opening B235, and the portion of the adjustment opening B235 not covered by the elastic member B7 forms a first opening B233 located above the elastic member B7 and a second opening B234 located below the elastic member B7. The elastic member B7, the leg support B230, and the hip support B210 together form the seat B6. In this embodiment, the number of elastic members B7 corresponds to the number of leg supports B230. That is, each leg support B230 is connected to the hip support B210 through an elastic member B7 at its approximately longitudinal center. In other embodiments, for each leg support portion B230, two or more elastic members B7 may be provided in the longitudinal portion of each leg support portion B230 between the first connection end B231 and the second connection end B232. The two or more elastic members B7 are spaced apart in the longitudinal direction, and the leg support portion B230 is connected to the hip support portion through these elastic members B7, so that at least a portion of the leg support portion B230 between the first connection end B231 and the second connection end B232 is not connected to the hip support portion B210. In an alternative embodiment, the elastic member B7 may not be provided between the leg support B230 and the hip support B210, and the leg support B230 may be switched between an open state and a closed state via an adjustment opening B235, allowing the leg support B230 to be expanded or retracted relative to the hip support B210.

As shown in Figure 33, the child carrier B1000 is also equipped with an adjustment mechanism B800, which is configured to expand or retract the hip support B210. When the leg support B230 is in the expanded position, it is positioned farther from the hip support B210 in the transverse width of the carrier assembly B200. This means that the outer edge B236 of the leg support B230 is positioned farther from the hip support B210 in the transverse width. This increases the width of the seat B6, making it wider. When the leg support B230 is in the retracted position, the leg support B230 leans against the hip support B210 in the transverse direction of the support assembly B200. This means that the outer edge B236 of the leg support B230 is closer to the hip support B210 in the transverse direction. This allows the seat B6 to have a smaller width. The adjustment mechanism B800 has an open and locked state. When the adjustment mechanism B800 is in the open state, the leg support B230 can expand relative to the hip support B210, thereby increasing the width of the seat B6. When the adjustment mechanism B800 is in the locked state, the leg support B230 retracts relative to the hip support B210, resulting in a smaller width of the seat B6.

As shown in Figures 34 and 35, the adjustment mechanism B800 includes a first adjustment member B810 and a second adjustment member B820. The first adjustment member B810 is connected to the first leg support B230e, and the second adjustment member B820 is connected to the second leg support B230f. The first adjustment member B810 includes a first adjustment strap B811 and a first mating portion B812 disposed on the first adjustment strap B811. The first adjustment strap B811 is connected between the first leg support B230e and the first mating portion B812. This means that the first mating portion B812 is connected to the first leg support B230e via the first adjustment strap B811. The second adjustment member B820 includes a second adjustment strap B821 and a second mating portion B822 disposed on the second adjustment strap B821. The second adjustment strap B821 is connected to the second leg support B230f. This means that the second mating portion B822 is connected to the second leg support B230f via the second adjustment strap B821. The second mating portion B822 is adapted to mate with the first mating portion B812 to detachably connect the first and second adjustment straps B811 and B821, thereby switching the adjustment mechanism B800 between an open and a locked state. When the first mating portion B812 and the second mating portion B822 engage (i.e., the adjustment mechanism B800 is locked), the two leg supports B230 lean against each other, thereby reducing the width of the seat B6 (i.e., making the seat B6 relatively narrow). When the first mating portion B812 and the second mating portion B822 separate (i.e., the adjustment mechanism B800 is open), the two leg supports B230 move apart, thereby increasing the width of the seat B6 (i.e., making the seat B6 relatively wide).

It should be noted that in this embodiment, when the adjustment mechanism B800 is in the open position, the relative position adjustment between the leg support B230 and the hip support B210 (i.e., the width adjustment of the seat B6) is the same as in the first or second embodiment described above and will not be further elaborated here.

As shown in Figures 34 and 35, one end of the first adjustment strap B811 is connected to the first leg support portion B230e and forms a first fixed end B8111. The first mating portion B812 is disposed on the first adjustment strap B811. One end of the second adjustment strap B821 is connected to the second leg support portion B230f and forms a second fixed end B8211, and the second mating portion B822 is disposed on the second adjustment strap B821. Furthermore, the first mating portion B812 can be movably disposed on the first adjustment strap B811 to allow adjustment of the length of the first adjustment strap B811 between the first fixed end B8111 and the first mating portion B812 (i.e., a first adjustment length), thereby adjusting the width of the seat portion B6 when the adjustment mechanism B800 is in the locked state. The second mating portion B822 is movably mounted on the second adjustment strap B821 to allow adjustment of the length of the second adjustment strap B821 between the second fixed end B8211 and the second mating portion B822 (i.e., the second adjustment length), thereby adjusting the width of the seat B6 when the adjustment mechanism B800 is in the locked state.

Of course, in some alternative embodiments, the first mating portion B812 may be fixedly mounted on the first adjustment strap B811, the second mating portion B822 may be fixedly mounted on the second adjustment strap B821, and both the first and second adjustment lengths may remain fixed. Alternatively, the first mating portion B812 may be movably mounted on the first adjustment strap B811, the second mating portion B822 may be fixedly mounted on the second adjustment strap B821, and the first adjustment length may be adjustable while the second adjustment length remains fixed. Alternatively, the second mating portion B822 may be movably mounted on the second adjustment strap B821, the first mating portion B812 may be fixedly mounted on the first adjustment strap B811, and the second adjustment length may be adjustable while the first adjustment length remains fixed.

Referring to Figure 34 , in this embodiment, the first mating portion is a male buckle, and the second mating portion is a female buckle adapted to engage with the male buckle. In alternative embodiments, the first mating portion is, for example, a hook, and the second mating portion is, for example, a ring. Alternatively, the first mating portion and the second mating portion are a pair of snaps that interlock. Alternatively, the first mating portion and the second mating portion are mating Velcro.

Returning to Figures 34 and 35 , the first and second adjustment straps B811 and B821 are each connected to the middle of the corresponding leg support B230. Specifically, the first and second fixing ends B8111 and B8211 are each connected to the middle of the corresponding leg support B230 in the longitudinal direction. The leg support B230 includes a first side B238 proximal to the hip support B210 and a second side B239 distal to the hip support B210. The first fixed end B8111 is connected to the second side B239 of the first leg support B230e, or to its first side B238, or between its second side B239 and its first side B238. The second fixed end B8211 is connected to the second side B239 of the second leg support B230f, or to its first side B238, or between its second side B239 and its first side B238. In this embodiment, the second side B239 of the leg support B230 forms the outer edge B236 of the leg support B230. The first fixed end B8111 and the second fixed end B8211 are respectively connected to the first side B238 of the corresponding leg support B230. The first adjustment strap B811 is connected to the front of the leg support B230 (i.e., the side of the leg support B230 facing away from the infant during use) or is connected inside the leg support B230 (i.e., between the layers if the leg support B230 is a multi-layered structure) via a first fixed end B8111. The first adjustment strap B811 is at least partially located on the front of the hip support B210 (i.e., the side of the hip support B210 facing away from the infant during use). The second adjustment strap B821 is connected to the front of the leg support B230 or is connected inside the leg support B230 via a second fixed end B8211. The second adjustment strap B821 is at least partially located on the front of the hip support B210. This facilitates operation of the first and second adjustment members B810 and B820, while also preventing them from interfering with the infant in the child carrier B1000.

As shown in Figure 34, the carrier assembly B200 is further provided with a first limiting ring B911 and a second limiting ring B912. The first adjustment strap B811 is inserted into the first limiting ring B911 to limit and guide the first adjustment strap B811. The second adjustment strap B821 is inserted into the second limiting ring B912 to limit and guide the second adjustment strap B821 and restrict its extension direction. Furthermore, the dimension of the first mating portion B812 in the depth direction is greater than the dimension of the first limiting ring B911 in that direction, and thus the movement of the first mating portion B812 toward the first fixed end B8111 is limited by the first limiting ring B911. Similarly, the dimension of the second mating portion B822 in the depth direction is greater than the dimension of the second limiting ring B912 in that direction, and the movement of the second mating portion B822 toward the second fixed end B8211 is also limited by the second limiting ring B912. The first limiting ring B911 and the second limiting ring B912 have the same structure, and the number of first limiting rings B911 can be one or more; the number of second limiting rings B912 can be one or more, and this application does not impose any restrictions on this. The first and second limiting rings B911, B912 are, for example, but not limited to, fabric loops sewn onto the front surface of the hip support B210. The first and second limiting rings B911, B912 are spaced apart in the transverse direction. The first fixing end B8111, the first limiting ring B911, the second limiting ring B912, and the second fixing end B8211 are generally located on the same straight line (or arc) in the transverse direction.

As shown in Figure 33, the carrier assembly B200 optionally includes a shielding member B920. Shielding member B920 is connected to the front of the carrier assembly B200 to cover the first and second adjusters B810 and B820, thereby enhancing the front appearance of the child carrier B1000. At least a portion of shielding member B920 is not connected to the carrier assembly B200, forming an access opening B921 between the shielding member B920 and the carrier assembly B200. This access opening B921 allows operation of the first and second adjusters B810 and B820. Specifically, shielding member B920 is, for example, a shielding fabric sheet. The shielding member B920 has an upper end B922 and a lower end B923 that are opposed in the depth direction. The upper end B922 and the lower end B923 of the shielding member B920 are each secured to the supporting assembly B200 by, for example, sewing. At least a portion of each side of the shielding member B920 in the transverse direction is not connected to the supporting assembly B200, thereby forming two transversely interconnected operating openings B921 between the shielding member B920 and the supporting assembly B200. More specifically, the first adjustment member B810 and the second adjustment member B820 extend between the shielding member B920 and the supporting assembly B200 through corresponding operation openings B921. The dimensions of the two operation openings are suitable for a user to insert their hands to operate the first adjustment member B810 and the second adjustment member B820. In this embodiment, the shielding member B920 and the supporting assembly B200 form a pocket B925 to accommodate the first adjustment member B810 and the second adjustment member B820. The operation opening B921 forms the opening of the pocket B925, through which the first adjustment member B810 and the second adjustment member B820 accommodated in the pocket B925 can be operated. In an alternative embodiment, the shielding member B920 is a multi-layer fabric structure, a pocket B925 is formed within the shielding member B920 (i.e., between the multiple layers of fabric), and an opening of the pocket 925 is provided between the multiple layers of fabric.

The operating principle of the child carrier B1000 in this embodiment is as follows.

When the width of the seat B6 required by the infant is smaller (for example, the infant is sitting forward in the child carrier B1000, or the infant is smaller in size), the adjustment mechanism B800 is kept in the locked state (that is, the first mating part B812 and the second mating part B822 cooperate with each other), and the outer edges B236 of the two leg support parts B230 are both leaned against the hip support part B210, so that the outer edges B236 of the two leg support parts B230 lean against each other, thereby reducing the width of the seat B6 (that is, making the seat B6 have a relatively smaller width). In this embodiment, the adjustment mechanism B800 limits the width of the seat B6 to a relatively narrow range, thereby better adapting to the width requirements of infants and young children. This avoids repeated adjustments of the leg supports B230 and makes the child carrier B1000 more convenient to use. Furthermore, when the adjustment mechanism B800 is locked, it provides a certain degree of support for the seat B6, thereby reducing the possibility of deformation and failure of the seat B6 and the elastic member B7.

If the infant requires a wider seat portion (B6) (for example, when the infant is sitting in the child carrier B1000 facing backwards, or the infant is larger), the following adjustments can be made.

Method 1: Switch the adjustment mechanism B800 to the open position (i.e., separate the first mating portion B821 from the second mating portion B822). The width of the seat B6 can be adjusted using the methods described in the first or second embodiment above, which will not be further elaborated here.

Method 2: Keep the adjustment mechanism B800 locked (i.e., the first mating portion B812 and the second mating portion B822 are engaged) and adjust the position of the first mating portion B812 on the first adjustment strap B811 (and/or the position of the second mating portion B822 on the second adjustment strap B821) to change the first adjustment length (and/or the second adjustment length), thereby increasing the width of the seat B6.

Example 4

The fourth embodiment of the present disclosure provides a child carrier B1000. As shown in Figure 36, the child carrier B1000 includes a waist belt B120, a shoulder belt B110, a carrying assembly B200 connected to the waist belt B120 and the shoulder belt B110, and a leg support B230 connected to the carrying assembly B200. The shoulder belt B110 is generally arranged along the longitudinal direction of the carrying assembly B200. One side of the carrying assembly B200 is connected to the waist belt B120, and the side of the carrying assembly B200 away from the waist belt B120 is detachably connected to the shoulder belt B110. That is, the upper side of the carrying assembly B200 is connected to the shoulder belt B110, and the lower side of the carrying assembly B200 is connected to the waist belt B120. The portion of the carrier assembly B200 near the waist belt B120 forms the hip support B210, while the upper side of the carrier assembly B200 forms the trunk support B220. The leg supports B230 are connected to the hip support B210 and, together with the leg supports B230, form the seat B6 for supporting an infant. The leg supports B230 can be switched between an extended and retracted position. When extended, the leg supports B230 are positioned farther from the hip support B210 across the width of the carrier assembly B200, allowing the seat B6 to be wider. When the leg support B230 is in the retracted position, it leans against the hip support B210 in the lateral direction of the support assembly B200, so that the seat B6 has a smaller width.

This embodiment differs from the child carrier B1000 in the aforementioned third embodiment in at least the following ways.

37 , the second connection end B232 of the leg support B230 is connected to the carrying assembly B200 or the waist belt B120. At least a portion of the first connection end B231 is formed as a movable end B231a, which is not connected to the carrying assembly B200. This is equivalent to the movable end B231a being unconnected, allowing the first connection end B231 to move relative to the leg support B230. In the depth direction, the portion of the leg support B230 between the first connection end B231 and the second connection end B232 is not directly connected to the hip support B210, so that at least a portion of the leg support B230 (in this embodiment, the middle portion of the leg support B230) is spaced apart from the hip support B210 and forms an adjustment opening B235. Specifically, the leg support B230 and the hip support B210 are connected via an elastic member B7, which at least partially covers the adjustment opening B235. The elastic member B7 is switchable between an extended state and a non-extended state, allowing the leg support B230 to expand or contract relative to the hip support B210. That is, in this embodiment, the middle portion of the leg support B230 is connected to the hip support B210 via the elastic member B7. In an alternative embodiment, the elastic member B7 may not be provided between the leg support B230 and the hip support B210, and a portion of the middle portion of the leg support B230 may be directly connected to the hip support B210.

As shown in Figures 36 and 37, the child carrier B1000 is also equipped with an adjustment mechanism B800. The first connection end B231 of one of the two leg supports B230 is adapted to connect to the first connection end B231 of the other leg support B230 via the adjustment mechanism B800. The adjustment mechanism B800 has an open and a locked state. When the adjustment mechanism B800 is in the open state, the width of the seat B6 is relatively large. When the adjustment mechanism B800 is locked, the first connection ends B231 of the two leg supports B230 are connected to each other through the adjustment mechanism B800. At this time, the width of the seat B6 is relatively small, smaller than the width of the seat B6 when the adjustment mechanism B800 is in the open position.

The adjustment mechanism B800 includes a first adjustment member B810 and a second adjustment member B820. The first adjustment member B810 includes a first adjustment band B811 and a first mating portion B812 provided on the first adjustment band B811. One end of the first adjustment band B811 is connected to the movable end portion B231a of the first leg support portion B230e, and the other end extends toward the second leg support portion B230f. The second adjustment member B820 includes a second adjustment band B821 and a second mating portion B822 provided on the second adjustment band B821. One end of the second adjustment band B821 is connected to the movable end portion B231a of the second leg support portion B230f, and the other end extends toward the leg support portion B230 to which the first adjustment band B811 is connected. The first adjustment strap B811 and the first leg support B230e are formed as an integral component, while the second adjustment strap B821 and the second leg support B230f are formed as an integral component. The first mating portion B812 is adapted to mate with the second mating portion B822 to connect the first adjustment strap B811 and the second adjustment strap B821 together. It is noteworthy that in this embodiment, the mobility of the two movable ends B231a of the leg support can be restricted by appropriate means, so that when the two adjustment members B810 and B820 are not connected, the movable ends B231a of the leg support can provide appropriate support, and the width of the seat B6 is relatively large. For example, a limiting structure may be provided at a position on the hip support B210 or shield B920 corresponding to the movable end B231a to limit the mobility of the movable end B231a. Alternatively, significant friction may exist between the movable end B231a and the hip support B210 and/or shield B920 under normal conditions, thereby limiting the mobility of the movable end B231a. In other embodiments, the movable end B231a of the leg support is highly mobile, rendering it unable to provide support when the two adjustment members B810 and B820 are disconnected, and the width of the seat B6 is relatively small.

Optionally, at least one of the second mating portions B822 and the first mating portions B812 is provided in at least two portions. This allows the first adjustment strap B811 and the second adjustment strap B821 to be connected to each other at different positions through the mating of the second mating portions B822 and the first mating portions B812. This allows the adjustment mechanism B800 to have different width adjustment positions for the seat portion B6.

Referring to Figures 36 and 37 , the number of first mating portions B812 is, for example, one, and the number of second mating portions B822 is, for example, at least two. The at least two second mating portions B822 include a second mating portion B822a and a second mating portion B822b, with the second mating portion B822a being closer to the first adjustment strap B811 in the transverse direction than the second mating portion B822b. When the first mating portion B812 is mated with the second mating portion B822a, the adjustment mechanism B800 is in the first locked state, the leg support portion B230 is in the first retracted state, and the seat portion B6 has a relatively large retracted width, which is smaller than the width of the adjustment mechanism B800 when it is in the open state. When the first mating portion B812 engages with the second mating portion B822b, the adjustment mechanism B800 is in the second locked state, the leg support portion B230 is in the second retracted state, and the seat portion B6 has a relatively small retracted width, which is smaller than the relatively large retracted width described above.

In some alternative embodiments, there are at least two first mating portions B812 and one second mating portion B822, allowing the adjustment mechanism B800 to have at least a first locked state and a second locked state. In other alternative embodiments, there are at least two first mating portions B812 and at least two second mating portions B822, allowing the adjustment mechanism B800 to have at least three seat width adjustment positions, thereby enabling the child carrier B1000 to better meet the seating width requirements of infants and young children. In still other alternative embodiments, one of the first mating portion B812 and the second mating portion B822 is provided, while the other is provided in multiple positions, also enabling the adjustment mechanism B800 to have multiple seat width adjustment positions.

Referring to Figure 37 , in this embodiment, the first adjustment strap B811 and the second adjustment strap B821 are each made of woven fabric. The first engaging portion B812 is, for example, a connecting buckle secured to the first adjustment strap B811 by sewing. The second engaging portion B822 is, for example, a buttonhole provided through the second adjustment strap B821. In an alternative embodiment, the second engaging portion B822 and the first engaging portion B812 are, for example, snap fasteners that can be interlocked. In another alternative embodiment, the second engaging portion B822 is, for example, a buckle, and the first engaging portion B812 is, for example, a hook adapted to be hooked onto the buckle.

As shown in Figures 36 to 38, the two first adjustment members B810 and the two second adjustment members B820 are at least partially located on the front of the carrier assembly B200. The carrier assembly B200 is also provided with a shielding member B920, which is connected to the front of the carrier assembly B200 to cover the first adjustment members B810 and the second adjustment members B820, thereby making the front of the child carrier B1000 more neat and beautiful. At least a portion of the shielding member B920 in the longitudinal direction is not connected to the carrier assembly B200, forming an operating port B921 between the shielding member B920 and the carrier assembly B200, thereby allowing the first adjustment member B810 and the second adjustment member B820 to be operated through the operating port. The size of the operating opening is suitable for the user to insert their hand to operate the first adjustment member B810 and the second adjustment member B820.

Example 5

The fifth embodiment of the present disclosure provides a child carrier B1000. As shown in Figure 39, the child carrier B1000 includes a waist belt B120, a shoulder belt B110, a carrying assembly B200 connected to the waist belt B120 and the shoulder belt B110, and a leg support B230 connected to the carrying assembly B200. The shoulder belt B110 is generally arranged along the longitudinal direction of the carrying assembly B200. One side of the carrying assembly B200 is connected to the waist belt B120, and the side of the carrying assembly B200 away from the waist belt B120 is detachably connected to the shoulder belt B110. That is, the upper side of the carrying assembly B200 is connected to the shoulder belt B110, and the lower side of the carrying assembly B200 is connected to the waist belt B120. The portion of the carrier assembly B200 near the waist belt B120 forms the hip support B210, while the upper side of the carrier assembly B200 forms the trunk support B220. The leg supports B230 are connected to the hip support B210 and, together with the leg supports B230, form the seat B6 for supporting an infant. The leg supports B230 can be switched between an extended and retracted position. When extended, the leg supports B230 are positioned farther from the hip support B210 across the width of the carrier assembly B200, allowing the seat B6 to be wider. When the leg support B230 is in the retracted position, it leans against the hip support B210 in the lateral direction of the support assembly B200, so that the seat B6 has a smaller width.

This embodiment differs from the aforementioned fourth embodiment in at least the following ways.

As shown in Figures 39 and 40, the first connection end B231 of one of the two leg supports B230 is adapted to be connected to the first connection end B231 of the other of the two leg supports B230 via an adjustment mechanism B800. The adjustment mechanism B800 includes a first adjustment member B810 and a second adjustment member B820. The first adjustment member B810 includes a first adjustment strap B811 and a first mating portion B812 disposed on the first adjustment strap B811. One end of the first adjustment strap B811 is connected to the movable end B231a of the first leg support B230e, while the other end is a movable end and is provided with a first mating portion B812. The second adjustment member B820 includes a second adjustment strap B821 and a second mating portion B822 disposed on the second adjustment strap B821. One end of the second adjustment strap B821 is connected to the movable end B231a of the second leg support B230f, while the other end is a movable end and is provided with a second mating portion B822.

39 and 40 , the carrier assembly B200 is further provided with a shielding member B920. Shielding member B920 is connected to the front of the carrier assembly B200 to cover the first and second adjusting members B810 and B820, thereby making the front of the child carrier B1000 more neat and aesthetically pleasing. In this embodiment, the carrier assembly B200 and shielding member B920 are further provided with a limiting channel B924 and an operating port B921 connected to the limiting channel B924, allowing for easy operation of the first and second adjusting members B810 and B820 through the operating port B921. The operating port B921 is located between the two connecting openings of the limiting channel B924. Specifically, the operating port B921 is located approximately in the middle of the width of the carrier assembly B200 and the shielding member B920 and communicates with the limiting channel B924. The limiting channel B924 is formed between the shielding member B920 and the carrier assembly B200, or within the shielding member B920. The first and second operating assemblies are respectively disposed within the limiting channel B924. The limiting channel B924 is formed as a channel extending transversely. In this embodiment, the shielding member B920 is sewn onto the carrier assembly B200. A first seam line B926 and a second seam line B927 are provided between the shielding member B920 and the supporting assembly B200. The first seam line B926 is further from the waistband B120 than the second seam line B927 (i.e., the second seam line B927 is located below the first seam line B926). A limiting channel B924 is formed between the first seam line B926 and the second seam line B927 to confine the first adjustment member B810 and the second adjustment member B820 within the limiting channel B924. The first seam line B926 and the second seam line B927 extend linearly in the width direction. The first seam line B926 includes at least two non-continuous line segments, and an operating port B921 is formed between the two adjacent line segments. In this embodiment, the operating port B921 is located on the side of the supporting assembly B200 and the shielding member B920 close to the trunk support portion B220.

Example 6

The sixth embodiment of the present disclosure provides a child carrier B1000. As shown in Figure 41, the child carrier B1000 includes a waist belt B120, a shoulder belt B110, a carrying assembly B200 connected to the waist belt B120 and the shoulder belt B110, and a leg support B230 connected to the carrying assembly B200. The shoulder belt B110 is generally arranged along the longitudinal direction of the carrying assembly B200. One side of the carrying assembly B200 is connected to the waist belt B120, and the side of the carrying assembly B200 away from the waist belt B120 is detachably connected to the shoulder belt B110. That is, the upper side of the carrying assembly B200 is connected to the shoulder belt B110, and the lower side of the carrying assembly B200 is connected to the waist belt B120. The portion of the support assembly B200 near the waist belt B120 forms the hip support B210, while the upper side of the support assembly B200 forms the trunk support B220. The leg support B230 is connected to the hip support B210 and, together with the leg support B230, forms the seat B6 for supporting an infant or young child. The leg support B230 is switchable between an extended state and a retracted state. When in the extended state, the leg support B230 is positioned farther from the hip support B210 across the width of the support assembly B200, allowing the seat B6 to have a greater width. When the leg support B230 is in the retracted position, it leans against the hip support B210 in the lateral direction of the support assembly B200, so that the seat B6 has a smaller width.

This embodiment differs from the child carrier B1000 in the aforementioned third embodiment in at least the following ways.

As shown in Figures 41 to 44, the child carrier B1000 is also equipped with an adjustment mechanism B800. The adjustment mechanism B800 is provided on the leg support B230 to allow the leg support B230 to be switched between an expanded state and a collapsed state, thereby adjusting the width of the seat B6. The adjustment mechanism B800 has an open state and a locked state. When the adjustment mechanism B800 is in the open state, the leg support part B230 is in the retracted state, the outer edge B236 of the leg support part B230 is extended, at least a portion of the outer edge B236 of the leg support part does not generate supporting force, a portion of the leg support part B230 and the hip support part B210 together form the seat part B6, and the effective width of the leg support part B230 is reduced, so that the seat part B6 has a smaller width. When the adjustment mechanism B800 is locked, the leg support B230 is extended, and the outer edge B236 of the leg support is shortened. This outer edge B236 is suitable for generating support force to support the infant riding in the child carrier B1000. The leg support B230 and the hip support B210 together form the seat B6. The effective width of the leg support B230 is increased, thereby making the seat B6 wider.

There are two leg supports B230, each equipped with an adjustment mechanism B800. For ease of description, the following uses one leg support B230 and the adjustment mechanism B800 configured thereon as an example.

As shown in Figures 42 and 43, the leg support B230 comprises a main body panel B230a and an adjustment panel B230b. One end of the main body panel B230a forms a first connection end B231, and the other end forms a second connection end B232. The first connection end B231 connects to the carrier assembly B200, while the second connection end B232 connects to the carrier assembly B200 or the waist belt B120. A portion of the adjustment panel B230b near the second connection end B232 is directly connected to the main body panel B230a. The other portion of the adjustment panel B230b near the first connection end B231 (i.e., the adjustment portion B230b1 of the adjustment panel B230b) is connected to the main body panel B230a via a tab B230c.

Optionally, the leg support portion B230 further includes a tab B230c, which is connected to at least one of the main body portion B230a and the adjustment tab B230b and shields the adjustment mechanism B800. Continuing with reference to Figures 42 and 43, the tab B230c is connected to the main body portion B230a and the adjustment tab B230b, respectively. The tab B230c shields the adjustment mechanism B800 from the back of the child carrier B1000 to prevent the adjustment mechanism B800 from interfering with the child riding in the carrier 1000. In some alternative embodiments, the tab B230c is connected to one of the main body portion B230a and the adjustment tab B230b and extends toward the other of the main body portion B230a and the adjustment tab B230b. It should be noted that "the tab B230c is connected to one of the main panel B230a and the adjustment panel B230b" can be understood as: the tab B230c is integrally formed with one of the main panel B230a and the adjustment panel B230b, or is fixedly connected to one of the main panel B230a and the adjustment panel B230b by means such as sewing, or is detachably connected to one of the main panel B230a and the adjustment panel B230b by means such as a zipper or snap fastener.

The adjustment mechanism B800 includes a first adjustment member B810 mounted on the adjustment plate B230b and a second adjustment member B820 mounted on the main plate B230a. The first adjustment member B810 is mounted on the adjustment portion B230b1 of the adjustment plate B230b.

When the first adjustment member B810 and the second adjustment member B820 engage (i.e., when the adjustment mechanism B800 is locked), the tab B230c is retracted. The adjustment member B230b is now connected to the main member B230a in the depth direction, providing support for the thighs. This gives the seat B6 a greater width.

When the first adjustment piece B810 and the second adjustment piece B820 separate, the tab B230c naturally expands. At this point, at least the portion of the adjustment piece B230b where the second adjustment piece B820 is located is no longer connected to the main piece B230a, and thus cannot provide thigh support. Consequently, only a portion of the leg support B230 and the hip support B210 together form the seat B6, resulting in a smaller width.

In other words, in this embodiment, the width of the seat B6 is varied by adjusting the width of the leg support B230 (i.e., the effective width of the leg support B230) through the adjustment mechanism B800, thereby meeting the seat B6 width requirements for children of different body shapes and different riding styles.

The first adjusting piece B810 includes a first mating portion B812. The second adjusting piece B820 includes a second mating portion B822. The first mating portion B812 is adapted to cooperate with the second mating portion B822 so that the adjusting mechanism switches between a locked state and an open state. The first mating portion B812 and the second mating portion B822 are, for example, zippers that can be pulled together. Specifically, the first mating portion B812 is fixed to the adjusting piece B230b, for example, by sewing, and the second mating portion B822 is fixed to the main piece B230a, for example, by sewing. In this embodiment, the second mating portion B822 is arranged on the front side of the main piece B230a (that is, the side of the main piece B230a facing away from the baby) and is located near the connecting piece B230c. The first mating portion B812 extends approximately longitudinally across at least a portion of the adjustment piece B230b, while the second mating portion B812 extends approximately longitudinally across at least a portion of the main piece B230a. In this embodiment, the first mating portion B812 extends approximately halfway across the adjustment piece B230b, meaning its lower end is approximately located in the longitudinal center of the adjustment piece B230b. The second mating portion B812 extends approximately halfway across the main piece B230a, meaning its lower end is approximately located in the longitudinal center of the main piece B230a.

The operating principle of the child carrier B1000 in this embodiment is as follows.

When the required seat B6 width is relatively large, the adjustment mechanism B800 is locked (i.e., the first and second mating portions B812 are pulled together). Due to the pulling action of the first and second mating portions B812, the area of the adjustment plate B230b where the first mating portion B812 is located also has a certain degree of support strength, providing support for the child while sitting. At this point, most or even all of the leg support B230 is able to provide support, increasing the effective width of the leg support B230 and, in turn, making the seat B6 relatively wide. With the elastic member B7 installed, the width of the seat portion B6 of the child carrier B1000 can be further adjusted. The adjustment principle and method are the same as those in the first embodiment described above and will not be further elaborated here.

When the required width of the seat B6 is relatively small, the adjustment mechanism B800 is switched to the open position (i.e., the first and second mating portions B812 are pulled apart). At this point, the first and second mating portions B812 no longer provide support for the opened portion of the adjustment plate B230b (the adjustment portion B230b1 provided with the first mating portion B812). At least a portion of the leg support portion B230 is unable to provide support, resulting in a smaller effective width of the leg support portion B230 and, in turn, a relatively smaller width of the seat B6.

In a variation of this embodiment, the leg support portion B230 includes a main body portion B230a, an adjustment portion B230b, and a tab B230c. The tab B230c is connected between the main body portion B230a and the adjustment portion B230b and can be switched between an expanded position and a folded and collapsed position. The upper end of the adjustment portion B230b is fixedly connected to the hip support portion B210 or the main body portion B230a. The child carrier B1000 further includes an adjustment mechanism 800 disposed on the leg support portion B230. The adjustment mechanism B800 includes a first adjustment member B810 disposed on the adjustment portion B230b and a second adjustment member B820 disposed on the main body portion B230a. When the first adjusting member B810 and the second adjusting member B820 are not connected, the tab B230c is in an extended state; when the first adjusting member B810 and the second adjusting member B820 are connected, the tab B230c is in a folded and retracted state. When the desired width of the seat B6 is relatively large, the adjustment mechanism B800 is kept in the open position (i.e., the first and second mating portions B812 are kept apart). The tab B230c is then extended, and both the adjustment tab B230b and the tab B230c can provide support, making the seat B6 relatively large in width. When the desired width of the seat B6 is relatively small, the adjustment mechanism B800 is switched to the locked position (i.e., the first and second mating portions B812 are closed). The adjustment tab B230b can provide support, while the tab B230c, folded and closed, cannot, resulting in a relatively small width of the seat B6.

Example 7

The seventh embodiment of the present disclosure provides a child carrier B1000. As shown in Figures 45 to 47, the child carrier B1000 includes a waist belt B120, a shoulder belt B110, a carrying assembly B200 connected to the waist belt B120 and the shoulder belt B110, and a leg support B230 connected to the carrying assembly B200. The shoulder belt B110 is arranged roughly along the longitudinal direction of the carrying assembly B200. One side of the carrying assembly B200 is connected to the waist belt B120, and the side of the carrying assembly B200 away from the waist belt B120 is detachably connected to the shoulder belt B110. That is, the upper side of the carrying assembly B200 is connected to the shoulder belt B110, and the lower side of the carrying assembly B200 is connected to the waist belt B120. The portion of the support assembly B200 near the waist belt B120 forms the hip support B210, while the upper side of the support assembly B200 forms the trunk support B220. The leg support B230 is connected to the hip support B210 and together with the leg support B230 forms the seat B6 for supporting an infant.

This embodiment differs from the third embodiment described above in at least the following ways.

As shown in Figures 45 to 47, the leg support B230 can be switched between an extended state (see Figures 45 and 47) and a retracted state (see Figure 46). When the leg support B230 is in the extended state, the outer edge B236 of the leg support is farther away from the hip support B210 in the width direction of the support assembly B200, thereby increasing the width of the seat B6. When the leg support B230 is in the retracted state, the outer edge B236 of the leg support is closer to the hip support B210 in the width direction of the support assembly B200, thereby decreasing the width of the seat B6. There are two leg supports B230, symmetrically positioned on the left and right sides of the hip support B210. Each leg support B230 includes a first side B238 proximal to the hip support B210 and a second side B239 distal to the hip support B210. The second side B239 forms the outer edge B236 of the leg support. The first side B238 is connected to the hip support B210, for example, by stitching. The child carrier B1000 is equipped with an adjustment mechanism B800. This mechanism B800 is used to adjust the position of the outer edge B236 of the leg support relative to the hip support B210, allowing the leg support B230 to switch between an extended and retracted position, thereby adjusting the width of the seat B6.

The adjustment mechanism B800 includes a first adjustment member B810 and a second adjustment member B820. The first adjustment member B810 is connected to the first leg support B230e, and the first adjustment member B810 is connected to the second leg support B230f. The first adjustment member B810 includes a first adjustment strap B811 and a first mating portion B812. One end of the first adjustment strap B811 is connected to the corresponding leg support B230 and forms a first fixed end B8111. The other end of the first adjustment strap B811 is a first adjustment end B8112 and is provided with a first mating portion B812. The first fixed end B8111 is away from the first side B238 of the corresponding leg support B230 and is connected to the approximately middle of the longitudinal depth of the corresponding leg support B230. The second adjustment member B820 includes a second adjustment strap B821 and a second mating portion B822 provided on the second adjustment strap B821. One end of the second adjustment strap B821 connects to the corresponding leg support B230, forming a second fixed end B8211. The other end of the second adjustment strap B821 forms a second adjustment end B8212 and is provided with a second mating portion B822. The second fixed end B8211 is distal from the second side B239 of the corresponding leg support B230 and is connected to the approximately mid-depth portion of the corresponding leg support B230. The second mating portion B822 is adapted to mate with the first mating portion B812 to detachably connect the first adjustment strap B811 and the second adjustment strap B821, thereby enabling the adjustment mechanism to switch between an open and a locked state.

Optionally, the adjustment mechanism B800 further includes a fixing member B830, which is disposed on the hip support portion B210. The first adjustment strap B811 is further provided with a first adapter B815, which is adapted to connect with the fixing member B830, thereby securing the first adjustment strap B811 to the hip support portion B210. The first mating portion B812 and the first adapter B815 are respectively disposed on either side of the first adjustment end B8112. Specifically, the first mating portion B812 is disposed on the front side of the first adjustment end B8112 and is adapted to mate with and connect with the second mating portion B822. The first adapter B815 is disposed on the back side of the first adjustment strap B811 and is adapted to mate with and connect with the fixing member B830. The second mating portion B822 is disposed on the back side of the second adjustment end B8212. When the first adjustment strap B811 is connected to the second adjustment strap B821 and to the fixing member B830 (i.e., the adjustment mechanism B800 is locked), the leg support B230 is retracted, and the seat B6 has a smaller width. When the first adjustment strap B811 is separated from the second adjustment strap B821 and from the fixing member B830 (i.e., the adjustment mechanism B800 is opened), the leg support B230 is extended, and the seat B6 has a larger width. Optionally, the width of the fixing member B830 is larger than the width of the first adapter B815, allowing the first adapter B815 to be connected to the fixing member at different locations, thereby adjusting the width of the seat B6.

In an alternative embodiment, the first fixed end B8111 of the first adjusting strap B811 is provided with a first mating portion B812, and the second fixed end B8211 of the second adjusting strap B821 is provided with a second mating portion B822. The fixing member B830 is provided on the hip supporting portion B210, and the first mating portion B812 and the second mating portion B822 are respectively adapted to be connected to the fixing member B830. In other words, in this embodiment, the first adjusting strap B811 and the second adjusting strap B821 are not directly connected, but are both connected to the fixing member B830. Specifically, the first mating portion B812 is provided on the back side of the first fixed end B8111, and the second adjusting strap B821 is provided on the back side of the second fixed end B8211. At this point, if necessary, one of the first adjustment strap B811 and the second adjustment strap B821 can be connected to the fixing member B830 to retract the unilateral leg support member B230 to have a smaller width.

Referring to Figures 45 to 47 , in this embodiment, the first mating portion B812 and the second mating portion B822 are, for example, Velcro fasteners that can be bonded together. The first adaptor B815 and the fixing member B830 are, for example, Velcro fasteners that can be bonded together. In some alternative embodiments, the first mating portion B812 and the second mating portion B822 are snap fasteners that can be snapped together; or, the first mating portion B812 is a hook, and the second mating portion B822 is a ring that mates with the hook. The first adaptor B815 and the fixing member B830 are snap fasteners that can be snapped together; or, the first adaptor B815 is a hook, and the fixing member B830 is a ring that mates with the hook.

Each leg support B230 is provided with an adjustment channel B23b, which extends along its width and has a connecting opening located away from the second side B239 (i.e., on the first side B238). The first and second adjustment straps B811 and B821 are respectively inserted through the corresponding adjustment channel B23b and exit through the corresponding connecting opening.

In an alternative embodiment, at least a portion of the leg support B230 between the first connection end B231 and the second connection end B232 is disconnected from the hip support B210, such that at least a portion of the leg support B230 (i.e., the middle portion of the leg support B230 in the longitudinal direction) is spaced apart from the hip support B210 and forms an adjustment opening B235. Alternatively, the leg support B230 and the hip support B210 are connected via an elastic member B7, which at least partially covers the adjustment opening B235. The elastic member B7 can be switched between an extended state and a non-extended state, allowing the leg support portion B230 to expand or contract relative to the hip support portion B210 (i.e., the edge line 236 of the leg support portion B230 can be moved away from or closer to the hip support portion B210).

The child carrier B1000 in this embodiment is detachably connected via a first adjustment strap B811 and a second adjustment strap B821. This allows the outer edge B236 of the leg support to be moved closer to or further from the hip support B210, thereby retracting or expanding the leg support B230 relative to each other, thereby changing the width of the leg support B230 and, in turn, the seat B6. The adjustment mechanism B800 of the child carrier B1000 provided in this embodiment is simple in structure, easy to adjust, and effectively adjusts the width of the seat B6.

(3) The third aspect of this application

The basic structural principle and technical problem solved in this design is to install seat height adjustment structures at different heights on the shoulder straps of the child carrier, which are selectively connected to the body section, enabling seat height adjustment and the detachable and replaceable body section.

The present disclosure will be described in detail below with reference to the accompanying drawings, wherein Figures 48 to 55 illustrate the structure of the child carrier C1 according to the present disclosure.

FIG48 schematically shows a front view of the child carrier C1 of the present application. The child carrier C1 includes a shoulder strap assembly C100 and a carrier sheet C200 connected to the shoulder strap assembly. An adult (schematically shown by the dotted line) can wear the child carrier C1 to carry a child.

The shoulder strap assembly C100 includes a shoulder strap C110 and a waist belt C120. The shoulder strap C110 is composed of two shoulder straps C111. The waist belt C120 is connected to the lower ends of the shoulder straps C111 at the adult's waist (not shown in FIG. 48 ) and is secured to the waist using, for example, a clip.

The carrier piece C200 includes a seat support area C210 for a child, a body piece C220 for supporting the child's body, and a thigh support piece C230. When worn, as shown in FIG48 , the carrier piece C200 is connected to the shoulder strap assembly C100 at the seat support area C210 at its lower end and flipped upward, allowing the upper end of the carrier piece C200 to be fixedly connected to the upper end of the shoulder strap assembly C100 via connectors such as clips, magnetic buckles, or buttons, for example, to the shoulder strap C111 of the shoulder strap assembly C100. In this case, a child-carrying compartment is formed between the shoulder strap assembly C100 and the carrier plate C200. The child's legs can extend from the sides of the seat support area C210 through the thigh support plate C230 to the child carrier C1, making the child more comfortable.

Figure 49 shows a front view of the child carrier C1 according to an embodiment of the present application in a first carrying position. In Figure 49, the connector connecting the upper end of the shoulder strap assembly C100 and the upper end of the body C220 of the carrier C200 is opened, and the body C220 is moved from the carrying position or child seating position shown in Figure 48 to a drooped position, that is, vertically downward. This allows the inner side of the seat carrying area C210, which was obscured by the body C220 in Figure 48, and the thigh support panels C230 on both sides of the seat carrying area C210 to be visible. In this position, it can be seen that the shoulder strap assembly C100 is provided with a first connector C130. According to this embodiment, the first connector C130 is located on the connecting strap C112, which horizontally connects the two shoulder straps C111. According to the present disclosure, the connecting strap C112 not only connects the two shoulder straps C111 but also serves as the first connector, making the height adjustment structure of the present disclosure more compact.

According to this embodiment, the first connector C130 can be in the form of a zipper or other connector forms, such as a clip or button. The first connector C130 is connected to a coupling member C212 disposed on the upper side of the seat support area C210 of the carrier sheet C200, thereby forming the first support state shown in Figure 49. According to this embodiment, the coupling member C212 is located on the edge of the seat support area C210 where it connects to the first connector C130. Corresponding to the first connector C130, the coupling member C212 can be in the form of a zipper or other connector forms, such as a clip or button.

According to this embodiment, the first connector C130 can be a female zipper with a zipper head, and the coupling member C212 can be a male zipper that mates with the female zipper; alternatively, the first connector C130 can be a male zipper, and the coupling member C212 can be a female zipper with a zipper head that mates with the male zipper.
