Patent Document 2: JP-A-2000-296734

Conventional posture maintaining cushions for infants are provided so as to be detachable as a whole from a seat portion such as a crib. Therefore, there is a possibility that the back cushion cannot be properly arranged on the seat or the position of the back cushion is misaligned with respect to the seat, so that the posture maintaining effect using the back cushion cannot be sufficiently obtained.

Contents of the invention

An object of the present invention is to provide a cushion capable of reliably exerting an effect of maintaining a baby's posture, and an infant support device using the cushion.

In order to solve the above problems, the present invention provides a cushion (5), which is applied to a seat (3) covered with a seat cover (4) that can be disassembled relative to the seat body (9). , the seat main body (9) functions as a core material imparting rigidity for maintaining the shape of the seat, and a concave-convex shape for supporting the infant is added to the surface of the seat cover, and it is characterized in that the infant The posture maintaining cushion includes at least one cushion-like member (10, 30, 50), which is manufactured as a different part through a process different from any of the seat body and the seat cover. At least one of the parts is a pad-like fixing part which, after its manufacture, is inseparably fixed relative to the surface of the seat body.

According to the cushion of the present invention, since at least one cushion-like member constituting the cushion is fixed to the seat, the cushion-like member is held at an optimum position relative to the seat, and the cushion-like member is not displaced relative to the seat. Therefore, since the infant is supported at an optimum position by the cushion-shaped member fixed to the seat, the posture-maintaining effect by the cushion-shaped member can be reliably exhibited.

In one aspect of the cushion according to the present invention, the cushion-shaped member may be fixed to the surface of the seat cover in an inseparable manner. According to the configuration in which the cushion-shaped member is fixed to the surface of the seat cover, since the cushion-shaped member is exposed on the seat surface, the position of supporting the infant by the cushion-shaped member can be clearly grasped. In addition, the fixing position of the cushion-like member on the seat can be changed by replacing the seat cover.

Alternatively, the pad-like member may be fixed to the surface of the seat main body in an inseparable manner. In this case, the seat cover deforms along with the cushion-like member fixed to the seat main body, thereby expressing a concavo-convex shape for supporting the infant on the surface of the seat. Since the seat cover can be detached while the cushion-like member fixed on the seat body remains on the seat main body, it is possible to omit removing the cushion-like member from the seat cover when washing the seat cover. The time to remove it.

In one aspect of the cushion of the present invention, the cushion includes a buttock pad (50) that supports the baby's buttocks as the pad-like member, the buttock pad is the pad-like fixing member, and the buttock pad It may be inseparably fixed relative to the surface of the seat body. The position suitable for supporting the baby's buttocks is substantially constant regardless of the baby's body shape. Therefore, even if the buttocks pad is inseparably fixed to the seat, the range of suitable body shapes for the seat will not be narrowed too much. Furthermore, when placing an infant on the seat, the position of the infant can be determined with reference to the buttocks pad. In addition, when the seat has the function of being folded down, when the back of the seat is raised, the buttocks of the child are blocked by the buttocks pad fixed to the seat to prevent the buttocks from moving forward.

In the method of fixing the buttocks pad, as the pad-shaped member, a head pad (10) and a waist pad (30) for respectively supporting the head and waist of the infant may be provided differently from the buttocks pad, The head pad and the waist pad are detachably provided with respect to the seat. When the baby's body is still small, the head and waist are supported by the head pad and waist pad, so it is hoped to prevent the head from tilting horizontally and the waist from moving horizontally, but wait until the head is erected or the upper body is stable. After that period, head and lumbar support is less necessary than hip support. According to the method that the hip pad is fixed and the head pad and the waist pad are detachably installed, the head pad and the waist pad are installed at the appropriate positions based on the hip pad when the baby is young. The waist pad supports the head and waist. As the baby grows, the head pad and waist pad can be removed, and only the hip pad is used to support the baby. The need for hip support can vary. As a result, the range of body shapes to which the cushion is suitable can be enlarged.

In order to solve the above problems, the present invention provides a supporting device for infants, comprising: a seat (3), which is covered by a seat cover (4) that can be disassembled relative to the seat main body (9) the main body, the seat main body functions as a core material imparting rigidity for maintaining the shape of the seat; The back cushion includes a cushion-like member (10, 30, 50) which is manufactured as a different part by a process different from any of the seat body and the seat cover, and , inseparably fixed to the surface of the seat main body, and a through hole is provided on the seat cover in alignment with the pad-shaped component fixed to the seat main body.

According to the infant support device of the present invention, the cushion-shaped member fixed to the seat body protrudes toward the surface of the seat cover through the through hole of the seat cover, thereby adding unevenness to the seat surface for supporting the infant. Since the cushion-shaped component is fixed on the seat body, the cushion-shaped component can be kept at the most suitable position relative to the seat, and the cushion-shaped component will not be misplaced relative to the seat. Therefore, the infant is supported at an optimum position by the cushion-shaped member fixed to the seat, and the posture-maintaining effect by the cushion-shaped member can be reliably exhibited. Since the seat cover can be detached while the cushion-like member fixed on the seat body remains on the seat main body, it is possible to omit removing the cushion-like member from the seat cover when washing the seat cover. The time to remove it. In addition, even if the seat cover contains interior materials such as elastic materials, the cushion-like member will not be directly exposed on the surface of the seat due to the influence of the interior material, so there is no damage to the position retention effect of the infant by the cushion-like member. The advantages.

In the above description, in order to facilitate the understanding of the present invention, the reference symbols of the drawings are marked in parentheses, but the present invention is not limited to the illustrated form. In the present invention, as long as there is no particular departure from the term infant, a wide range from infant stage to school age is included.

As described above, according to the cushion and infant supporting device of the present invention, by fixing at least one cushion-shaped member constituting the cushion to the seat, the cushion-shaped member is held at an optimum position relative to the seat, and the cushion-shaped Since there is no misalignment of the member with respect to the seat, the cushion-like member fixed to the seat can support the infant at an optimal position, and the posture-maintaining effect of the cushion-like member can be reliably exhibited.

The seat main body is made of resin or the like, whereby rigidity for forming the shape of the seat is imparted to the seat main body. In other words, the seat main body functions as a core material providing rigidity for maintaining a constant shape of the seat by relying only on the seat 3 itself without relying on other support mechanisms. The seat 3 may be bent along the curve L1. The seat cover 4 is detachable from the seat body. The back cushion 5 of the first aspect of the present invention is provided on the seat cover 4 . The back cushion 5 has, as a cushion-like member, a head pad 10 disposed in the head support area A1 of the seat 3, a pair of left and right lumbar pads 30 disposed in the lumbar support area A2 of the seat 3, and a pair of left and right lumbar pads 30 disposed in the seat 3. Hip pad 50 in hip support area A3. These pads 10 , 30 , 50 are formed as different parts independent of each other. In addition, the gaskets 10 , 30 , and 50 are manufactured as different parts by different processes with respect to either the seat body of the seat 3 or the seat cover 4 .

The head pad 10 has a base portion 11 and a protruding portion 12 provided along the outer periphery of the base portion 11 . The base portion 11 is formed in a flat plate shape having a circular outer peripheral shape. The protruding portion 12 has a neck support portion 13 extending along the lower side of the head cushion 10 , and a pair of side head support portions 14 extending along both sides of the head cushion 10 . The neck support portion 13 is provided to support the nape of the infant, and the side head support portion 14 is provided to support the infant's head from the side. The neck support part 13 and the side head support part 14 are connected as one.

An elastic material having moderate elasticity may be provided on the head pad 10 as an interior material. Elastic materials such as cotton, polyurethane, low-repulsion polyurethane, and gel can be used as interior materials. The interior material may be provided only on the protruding portion 12 , or may be provided on both the base portion 11 and the protruding portion 12 .

Each lumbar pad 30 is formed as a protrusion whose height gradually decreases in all directions from its apex 30a. These waist pads 30 are attached to the waist of the baby from both sides, and are used to prevent the baby's waist from moving laterally. The outer peripheral shape of the waist pad 30 can be formed in various shapes such as a circle, an ellipse, an oblong shape, a bag shape, and an egg shape. For the waist portion 30, an elastic material having moderate elasticity can also be used as an interior material. Elastic materials such as cotton, polyurethane, low-repulsion polyurethane, and gel can be used as interior materials. In addition, the left and right waist pads 30 may be connected to each other by the same base portion as the base portion 11 of the head pad 10 .

The buttock pad 50 has a base portion 51 and a protrusion portion 52 extending in the left-right direction on the base portion 51 . The base portion 51 is formed in a flat plate shape similarly to the base portions 11 and 31 of the head pad 10 and the waist pad 30 . The protruding portion 52 has a hip support portion 53 and a pair of knee support portions 54 arranged at both ends of the hip support portion 53 . The hip support part 53 is provided to support the buttocks of the infant, and the knee support part 54 is provided to support the knees of the infant from the side. The hip support part 53 and the knee support part 54 are integrally connected.

For the hip pad 50, an elastic material having moderate elasticity may be provided as an interior material. Elastic materials such as cotton, polyurethane, low-repulsion polyurethane, and gel can be used as interior materials. The interior material may be provided only on the protruding portion 52 , or may be provided on both the base portion 51 and the protruding portion 52 .

The pads 10 , 30 , 50 constituted as described above are fixed to the surface of the seat cover 4 so that they cannot be separated. As a method of fixing the gaskets 10, 30, 50, hot pressing, that is, a fixing method using melting of resin or the like by heat, sewing, bonding, and other various fixing methods can be used. Therefore, if the pads 10, 30, 50 are fixed on the surface of the seat cover 4, the pads 10, 30, 50 can be held at the most suitable position on the seat cover 4, and the pads 10, 30, 50 can be prevented from 50 relative to the seat cover 4, the posture maintaining effect of the pads 10, 30, 50 can be reliably and reliably exhibited. In addition, since the pads 10, 30, 50 are fixed to the seat cover 4, which is detachable from the seat body, the pads 10, 30, 50 are exposed on the surface of the seat 3, and it is possible to clearly grasp the space based on these pads. The bearing position of the pads 10, 30, 50. In addition, the fixed positions of these pads 10 , 30 , 50 on the seat 3 can be changed by replacing the seat cover 4 . For example, prepare a plurality of seat covers 4 suitable for different body shapes, select these seat covers 4 appropriately, and install them on the seat body, thereby, one seat body can be adapted to infants of various body shapes. .

In the manner described above, all the pads 10, 30, 50 are fixed on the seat cover 4, but it is also possible to fix a part of the pads on the seat cover 4 and set the other pads to be opposite to the seat cover. 4 disassemble freely. For example, as shown in FIG. 3 , the head gasket 10 can be installed in a position-adjustable and detachable state relative to the seat cover 4 in the up-down direction of the seat 3 (the up-down direction in FIG. 2 and FIG. 3 ), On the other hand, the waist pad 30 and the hip pad 50 may be fixed to the seat cover 4 so as not to be separated. According to this example, the baby is placed on the seat cover 4 based on the buttocks pad 50, and the seat 3 can be enlarged by changing the position of the head pad 10 as shown by the phantom line in the figure according to the body shape of the baby. Range of acceptable toddler body shapes. The position suitable for supporting the baby's buttocks is almost constant regardless of the baby's body shape. Therefore, the buttocks pad 50 is most suitable as a pad-like member that is inseparably fixed to the seat cover 4 . Furthermore, when the buttocks pad 50 is fixed to the seat cover 4 , the buttocks pad 50 will not be misaligned on the seat cover 4 . Therefore, there is an advantage that the hip pad 50 can reliably suppress the forward movement of the hip when the back of the seat portion 30 is raised. In addition, not only the head pad 10 but also the waist pad 30 may be detachably installed with respect to the seat cover 4 . In addition, the waist pad 30 may be provided so that the position of the seat 3 can be adjusted in the vertical direction or the horizontal direction with respect to the seat cover 4 .

[Second way]

4 and 5 show the seat main body of the seat to which the cushion according to the second aspect of the present invention is applied. This aspect is common to the above-mentioned first aspect in that the head pad 10 , the pair of waist pads 30 , and the hip pads 50 are provided as the cushion-shaped member fixed to the seat. In addition, the structure of the spacer 10, 30, 50 is the same as that of the 1st form. However, the second aspect is different from the first aspect in that the pads 10, 30, 50 cannot be separately fixed to the surface of the seat body 9. FIG. The seat main body 9 is formed by combining the back panel 9A and the seat panel 9B in a bendable manner along the curve L1, the head pad 10 and the waist pad 30 are fixed to the back panel 9A, and the buttock pad 50 is fixed to the seat panel 9B. . On the surface of the seat main body 9, a seat cover having a structure in which the back cushion 5 of the first embodiment is removed is detachably attached.

According to the second mode, by putting the seat cover 4 on the seat main body 9, the seat cover 4 is deformed according to the concave-convex shape of the pads 10, 30, 50, thereby attaching the baby support to the surface of the seat 3. Bump shape. In the case where the pads 10, 30, 50 are fixed to the seat body 9, these pads 10, 30, 50 can also be left on the seat body when the seat cover 4 is detached from the seat body 9. 9 on. Therefore, when the seat cover 4 is washed, the effort of detaching the cushion 5 from the seat cover 4 can be saved.

In the second form, some of the gaskets 10, 30, and 50 may be fixed to the seat body 9 so that they cannot be separated, and on the other hand, other gaskets may be fixed to the seat body 9 so as to be detachable. disassembly. Furthermore, the position can be adjusted in the up-down direction of the seat part 3 with respect to the pad which can be attached and detached with respect to the seat part main body 9. As shown in FIG. In this case, for the reason described above, the buttocks pad 50 is most preferably a pad member fixed inseparably to the seat body 9 .

In addition, as shown in FIG. 6 , through-holes 4 a , 4 b , and 4 c may be provided on the seat cover 4 in accordance with the mounting positions of the gaskets 10 , 30 , and 50 . According to the infant support structure provided with such through holes 4a-4c, when the seat cover 4 is detached from the seat main body 9, it is not necessary to remove the cushion 5, and since the surface of the seat 30 directly exposes the cushion 10 . When an elastic material or the like is incorporated in the seat cover 4 , there is an advantage that the posture maintaining effect by the pads 10 , 30 , 50 is not affected by the interior material of the seat cover 4 .

The present invention is not limited to the above structures, but can be implemented in any appropriate manner. For example, the head pad 10 may have a structure in which the neck support part 13 and the side head support part 14 are separated. The cushion of the present invention is not limited to the structure having a head pad, a waist pad, and a buttock pad, and a part of the pad may be omitted, or a pad-like component may be further added. The infant products to which the present invention is applied are not limited to baby carriages, and various infant products requiring cushions such as baby frames and child seats can be used as its applicable objects.
