DETAILED DESCRIPTION

The disclosure relates generally to a highchair. Highchairs are typically used to support children in an upright position. The highchair disclosed herein may be fitted to support children at various developmental stages, including a newborn, infant, or toddler. In certain embodiments, the highchair may be designed or fitted to support an infant. The highchair may include one or more inserts, such as a booster or head and/or body support cushion, to provide appropriate support for a child of the target developmental stage. While the disclosure refers generally to a highchair, it should be understood that the embodiments described herein may be used with a chair fitted to support older children, for example, a preschooler or school-age child.
FIG. 1 is a perspective view of a highchair as described herein. The highchair may include a seat 100 having a backrest and a bottom surface. The backrest may be defined as a substantially vertical semi-planar structure of the seat 100 for lumbar, neck, and/or head support. The bottom surface may be defined as a substantially horizontal semi-planar structure of the seat 100 for seated support. The backrest and/or bottom surfaces of the seat 100 may optionally be concave or comprise concave portions to provide ergonomic support.
The seat 100 may be fixed or mountable to one or more bases. In FIG. 1 , the seat is shown mounted to a free-standing base including four legs, 400 a-400 d. In some embodiments, the seat 100 may be mountable to a structure or a supportable base. The seat 100 may be a component of a modular child seating system. The modular child seating system may include the seat 100 and a base, such as the free-standing base or a supportable base. The supportable base may be fixed or mountable to a support structure or the seat 100 may be mountable to the support structure. In some embodiments, the seat 100 may comprise at least one connection mechanism configured to mate with a corresponding connection mechanism of the free-standing base and/or a corresponding connection mechanism of the supportable base.
The seat 100 may be formed of a plastic material. Exemplary plastic materials include nylon, acrylic, polypropylene, and polyethylene (such as cross-linked polyethylene (PEX)). Other plastics, such as hard plastics, may be used. In some embodiments, the plastic may be selected to be substantially non-porous for easy cleaning. In some embodiments, the plastic material may be reinforced with a metal core. Exemplary metal materials include aluminum and stainless steel. Other metal reinforcement materials may be used. The seat 100 may comprise elements formed of a flexible or semi-flexible fabric material. For example, a horizontal crossbar or vertical crossbar may be formed of a fabric material. In some embodiments, the seat 100 may comprise an insert (not shown) formed of a fabric material, such as a booster or cushion. Exemplary fabric materials include polyester, nylon, and blends thereof. Other fabric materials may be used.
The highchair may comprise a footrest 600. The footrest 600 may be positioned between first and second legs of the base, for example, legs 400 a, 400 b (FIG. 1 ). The footrest 600 may be configured into more than one position for foot support. In certain exemplary embodiments, the footrest 600 may be adjusted into a first position for foot support (FIG. 2A) and a second position for foot support (FIG. 2B). In exemplary embodiments, the footrest 600 may be rotated between the first position and the second position. For example, the entire footrest 600 or at least a portion of the footrest 600 may be rotated between the first position and the second position. In other embodiments, the footrest 600 may be lowered or elevated between the first position and the second position. While the description relates generally to first and second positions for foot support, it should be understood that, in certain embodiments, the footrest 600 may be configured into more than two positions for foot support, for example, three, four, five, six, or more positions for foot support.
The first position for foot support and the second position for foot support are similar, except that the footrest 600 has a different height (distance from the seat 100) at each position. Thus, children of different heights may comfortably use the same highchair, or the footrest 600 may be adjusted into a lower position once the child grows out of the higher position. The footrest 600 position may be selected to provide a footrest 600 height (distance from the seat 100) appropriate for use by a child of the target developmental stage when seated in the highchair. In some embodiments, the first (lower) position may be at least 24 inches lower than the second (highest) position, and thus at least 24 inches farther from the seat 100. For instance, the first position may be 24-18 inches lower, 18-12 inches lower, or 12-6 inches lower than the second position.
The footrest 600 may have a bottom support 630. The bottom support 630 may be defined as an elongated planar structure for foot support. The bottom support 630 may have a first planar surface 632 for foot support. In some embodiments, the bottom support 630 may have a second planar surface 634 for foot support opposite the first planar surface 632. The footrest 600 may have a first lateral support 640 a and a second lateral support 640 b. Each lateral support 640 a, 640 b may be positioned at a distal end of the footrest 600, for example, adjacent a distal end of the bottom support 630. Thus, the bottom support 630 may extend between opposite lateral supports 640 a, 640 b. The lateral supports 640 a, 640 b may be positioned to connect the footrest 600 to the legs 400 a, 400 b, for example, between the bottom support 630 and the legs 400 a, 400 b.
The lateral supports 640 a, 640 b may have an elongated profile. For instance, the lateral supports may have a length greater than their width and depth. Along the length dimension, the lateral supports 640 a, 640 b may have a first end opposite a second end. The first end may be connected to the bottom support 630. The second end may be connected to a respective leg 400 a, 400 b of the base.
The lateral supports 640 a, 640 b may comprise a portion extending between the first end and the second end. The portion between the first end and the second end may be dimensioned to define a height difference between the first position and the second position of the footrest 600. The height difference may be approximately 2× the dimension between the first end and the second end of the lateral support 640 a, 640 b. In some embodiments, the dimension between the first end and the second end may be at least 12 inches, for example, 12-9 inches, 9-6 inches lower, or 6-3 inches.
The dimensions of the footrest 600, for example, lateral support 640 a, 640 b (length, thickness, pivot point, diameter of the arc of rotation, etc.) may be selected based on the target developmental stage of the child. Each dimension may have an effect on the footrest 600 height (distance from the seat 100). Thus, the dimensions may be selected to be appropriate for use by the child of the target developmental stage when seated in the highchair. In certain exemplary embodiments, the dimensions may be selected to provide an appropriate footrest 600 height (in the first position and in the second position) for an average toddler (e.g., 1-3 years of age).
In some embodiments, the lateral supports 640 a, 640 b may be fixed to the bottom support 630. For instance, the first end of each lateral support 640 a. 640 b may be fixed to a corresponding end of the bottom support 630. In these embodiments, the bottom support 630 is not independently rotatable with respect to the lateral supports 640 a, 640 b. The lateral supports 640 a, 640 b may be substantially perpendicular to the bottom support 630. Alternatively, the lateral supports 640 a, 640 b may form a non-perpendicular angle with the bottom support 630. In other embodiments, the first end of each lateral support 640 a, 640 b may be rotatably connected to a corresponding end of the bottom support 630. In these embodiments, the bottom support 630 may be independently rotatable with respect to the lateral supports 640 a, 640 b.
Each lateral support 640 a, 640 b may be rotatably connected to the corresponding leg 400 a, 400 b. The second end of the lateral support 640 a, 640 b may be rotatably connected to the corresponding leg 400 a, 400 b. Thus, the lateral support 640 a, 640 b may be configured to rotate about a connection point with the corresponding leg 400 a, 400 b, also referred to as a “pivot point” herein.
The footrest 600 may be configured into the first (lower) position for foot support by rotating the lateral support 640 a. 640 b down leg 400 a, 400 b, lowering the bottom support 630. The footrest 600 may be configured into the second (higher) position for foot support by rotating the lateral support 640 a, 640 b up leg 400 a, 400 b, raising the bottom support 630. In general, the first planar surface 632 may be used in the first position for foot support. As shown in FIG. 2A, in the first position for foot support the first planar surface 632 is facing up. This arrangement may be used whether the bottom support 630 is fixed to the lateral supports 640 a, 640 b or rotatably connected to the lateral supports 640 a, 640 b.
In some embodiments, the second planar surface 634 may be used in the second position for foot support. As shown in FIG. 2B, after a rotation from the first position, in the second position for foot support the second planar surface 634 is facing up and the first planar surface 632 is facing down. This arrangement may be used when the bottom support 630 is fixed to the lateral supports 640 a. 640 b. In such a configuration, the rotation of the footrest resembles a swing. For the rotation, the entire footrest 600 (bottom support 630 and lateral supports 640 a, 640 b) is flipped to transition from the first position with the first planar surface 632 facing up to the second position with the second planar surface 634 facing up. In this embodiment, the single point of rotation (shown as release actuators 650 a, 650 b, FIGS. 3A-3D) is the second end of the lateral supports 640 a, 640 b, which is rotatably connected to the legs 400 a, 400 b.
In some embodiments, the first planar surface 632 is also used in the second position for foot support. This arrangement may be used when the bottom support 630 is rotatably connected to the lateral supports 640 a, 640 b, for example, when the bottom support 630 is independently rotatable with respect to the lateral supports 640 a, 640 b. As shown in FIGS. 7A-7E, the lateral supports 640 a. 640 b rotate about the rotatable connection with the legs 400 a, 400 b while the bottom support 630 simultaneously rotates about the rotatable connection with the lateral supports 640 a, 640 b to maintain planar surface 632 facing up.
In this embodiment, the footrest includes two points of rotation (FIGS. 8A-8E), the first point of rotation (shown as rotator 610) is the second end of the lateral supports 640 a, 640 b, which is rotatably connected to the legs 400 a, 400 b, and the second point of rotation (shown as rotator 710) is the first end of the lateral supports 640 a, 640 b, which is rotatably connected to the bottom support 630. In some embodiments, the bottom support 630 may have only the first planar surface 632 for foot support. The opposite surface of the bottom support 630 may be rounded or otherwise not configured, dimensioned, or reinforced for foot support. In other embodiments, the bottom support 630 may still have two opposite planar surfaces 632, 634. The user may select whether to rotate the bottom support 630 for use of the first planar surface 632 for foot support in the first and second positions or not rotate the bottom support 630 for use of the second planar surface 634 for foot support in the first or second position.
The transition path between the first and second positions may define an arc of rotation (FIG. 6 ). The arc of rotation may be defined as the path taken by the first end of the lateral support 640 a, 640 b (connected to the bottom support 630). The first (lowest) position may be at least 150° from the second (highest) position along the arc of rotation. For example, the first position may be 150°-160°, 160°-170°, 170°-180°, or 180°-190° from the second position. In some embodiments, additional intermediate positions may exist between the first and second positions.
In some embodiments, the footrest 600 may rotate at least 150°. For example, the footrest 600 may rotate at least 160°, at least 170°, at least 180°, at least 190°, at least 200°, at least 210°, at least 220°, at least 230°, at least 240°, or more. In certain embodiments, the footrest 600 may rotate 360°. The footrest 600 may rotate less than 360º, less than 300°, less than 270°, less than 240°, less than 210°, or less than 180°.
In some embodiments, the bottom support 630 may independently rotate at least 150°. For example, the bottom support 630 may rotate at least 160°, at least 170°, at least 180°, at least 190°, at least 200°, at least 210°, at least 220°, at least 230°, at least 240°, or more. In certain embodiments, the bottom support 630 may rotate 360º. The bottom support 630 may rotate less than 360º, less than 300°, less than 270°, less than 240°, less than 210°, or less than 180°.
In other embodiments, the lateral support 640 a. 640 b may be fixed to the respective leg 400 a, 400 b and/or the footrest may lack a point of rotation. The bottom support 630 may be slidably engaged with the lateral support 640 a, 640 b. The bottom support 630 may be positioned to transition between the first position and the second position by being lowered and elevated along the lateral supports 640 a, 640 b. In this embodiment, a lower end of the lateral support 640 a, 640 b may be associated with the first (lower) position and an upper end of the lateral support 640 a, 640 b may be associated with the second (higher) position.
Thus, in some embodiments, the bottom support 630 may be positioned on a track fixed to the lateral supports 640 a, 640 b. Each lateral support 640 a, 640 b may have a corresponding track. The track may be a vertical track. The track may define a channel protruding from the lateral supports 640 a. 640 b or embedded in the lateral supports 640 a, 640 b. The track may extend vertically, up and down along at least a portion of the lateral supports 640 a, 640 b. The bottom support 630 may be fixed to wheels or chains movable along the tracks. In some embodiments, the track may comprise a slidable cover to prevent food and other debris from contacting the track.
The footrest 600 may comprise one or more rotators 610. For example, the footrest 600 may comprise two rotators, three rotators, four rotators, or more. Rotators 610 may be positioned at each point of rotation of the footrest 600. The rotator 610 may be configured to rotate the footrest 600 into the first and second positions. The rotator 610 may be defined as a mechanical joint for enabling rotation of one part relative to another. One exemplary rotator joint is formed between rotator ring 610 (FIG. 4A) and rotator plate 612 (FIG. 4B). As shown in FIGS. 4A-4B, exemplary rotator ring 610 is positioned on leg 400 a, while rotator plate 612 is positioned on lateral support 640 a. Similar rotators may be positioned between leg 400 b and lateral support 640 b, and at other rotatable connections around the highchair.
Rotator ring 610 may comprise a lip 614 configured to fit into and rotate about a corresponding channel 616 on the rotator plate 612. The channel 616 may be a circular channel. The lip 614 may be dimensioned to extend around all or a portion of the circumference of the rotator ring 610. In some embodiments, the lip 614 may be formed of one or more flanges. The exemplary lip 614 shown in FIG. 4A is formed of two flanges. In some embodiments, the lip 614 is fixed in position. In other embodiments, the lip 614 is retractable for removal of the rotator 610 from the rotator plate 612. In some embodiments, for example, as shown in FIGS. 4A-4B, the channel 616 comprises openings for removal of the rotator 610 from the rotator plate 612. In other embodiments, the channel 616 is free of such openings. Thus, in some embodiments, the footrest 600 is removable from the legs 400 a, 400 b. In other embodiments, the footrest 600 is not removable from the legs 400 a, 400 b.
The rotator joint may be formed of corresponding mechanical features, such as rotator ring 610 and rotator plate 612. The exemplary rotator shown in FIGS. 4A-4B is formed from ring 610 fixed to leg 400 a and plate 612 fixed to lateral support 640 a. In other embodiments, rotator ring 610 may be fixed to lateral support 640 a with rotator plate 612 fixed to leg 400 a. Thus, one mechanical feature may be fixed or formed on a first part such as the leg 400 a, with a corresponding mechanical feature fixed or formed on a second part such as the lateral support 640 a, making the second part (lateral support 640 a) rotatable with respect to the first part (leg 400 a).
In some embodiments, the footrest 600 may comprise a bottom support 630 rotator 710 (FIGS. 8A-8E). Bottom support rotator 710 may be configured to rotate the bottom support 630 with respect to the lateral supports 640 a, 640 b. In some embodiments, the rotator 710 may comprise a ring and corresponding plate, as previously described. The ring may be fixed to a respective lateral support 640 a, 640 b with a rotator plate fixed to bottom support 630. Alternatively, the ring may be fixed to bottom support 630 with a rotator plate fixed to a respective lateral support 640 a, 640 b.
The rotators 610 and 710 may enable rotation in a single plane, two planes, or three planes. Exemplary rotator 610 is positioned to rotatably connect a respective lateral support 640 a to an adjacent leg 400 a of the base. A similar rotator (not shown) may be positioned to rotatably connect lateral support 640 b to adjacent leg 400 b. Exemplary rotator 710 is positioned to rotatably connect a respective lateral support 640 b to bottom support 630. A similar rotator (not shown) may be positioned to rotatably connect respective lateral support 640 a to bottom support 630.
The footrest 600 may comprise one or more locking mechanism 620. For example, the footrest 600 may comprise one locking mechanism, two locking mechanisms, three locking mechanisms, four locking mechanisms, or more. The locking mechanism 620 may comprise a mechanical or digital feature configured to lock the footrest 600 (for example, the rotator 610) into a desired position for foot support. Locking mechanism 620 may be positioned to correspond with rotator 610 of the footrest 600. In some embodiments, a footrest comprising rotator 710 may comprise a corresponding locking mechanism (not shown) for rotator 710.
In some embodiments, the locking mechanism 620 may lock the footrest 600 in pre-set positions, such as the first position and the second position (e.g., FIGS. 3A-3D). In some embodiments, the locking mechanism 620 may lock the footrest 600 in more than two pre-set positions for foot support, for example, three, four, five, six or more positions for foot support. Five positions for foot support are shown in FIGS. 7A-7E, respectively. Rotators 610 and 710 in each of these five positions are shown in FIGS. 8A-8E. In some embodiments, the locking mechanism 620 may lock the footrest 600 at any desired position along the arc of rotation, for example, any position between the first position (lowest) and the second position (highest). In some embodiments, the locking mechanism 620 may also lock the footrest 600 in a position for storage (for example, a position that is not used for foot support).
One exemplary locking mechanism 620 is formed between locking mechanism peg (denoted 620 in FIG. 4A) and a corresponding locking mechanism slot 622 (FIG. 4B). Locking mechanism peg 620 is positioned on rotator 610. Locking mechanism slot 622 is positioned on rotator plate 612. In use, locking mechanism peg 620 may engage locking mechanism slot 622 to prevent rotation of the footrest 600. Locking mechanism peg 620 may be retractable. Locking mechanism peg 620 may be retracted to disengage locking mechanism slot 622, allowing rotation of footrest 600. The locking mechanism 620 may comprise one or more pegs, for example, two, three, four, five, six or more pegs. In other embodiments, the locking mechanism 620 may have only one peg.
In one exemplary embodiment, locking mechanism 620 includes two pegs 620 and two slots 622. Pegs 620 and slots 622 may correspond to the first position for foot support in a first arrangement, and a second position for foot support when rotated into a second opposite arrangement. However, the locking mechanism may be formed between one peg 620 and two slots 622, each slot 622 associated with a position for foot support. The locking mechanism may comprise more than two pegs 620 and/or more than two slots 622. For additional positions for foot support (for example, more than two positions), the locking mechanism may comprise at least additional slots 622. In some embodiments, at least one slot 622 is provided for each position for foot support.
The footrest 600 may comprise one or more release actuators 650 a, 650 b. For example, the footrest 600 may comprise one release actuator, two release actuators, three release actuators, four release actuators, or more. Release actuators 650 a, 650 b may be associated with a corresponding locking mechanism 620. Release actuators 650 a, 650 b may comprise a mechanical or digital deactivator of the locking mechanism 620. The release actuators 650 a, 650 b may be configured to release the locking mechanism 620, allowing rotation of the rotator 610. In some embodiments, release actuators may be provided for rotator 710.
In some embodiments, the release actuators 650 a, 650 b are positioned proximate the locking mechanism 620. Thus, the release actuators 650 a, 650 b may be positioned proximate corresponding rotator 610. Exemplary release actuators 650 a, 650 b may be positioned on or adjacent lateral supports 640 a, 640 b, or accessible from a point on or adjacent lateral supports 640 a, 640 b, for example, on or adjacent a second end of lateral supports 640 a, 640 b, at a connection point with corresponding legs 400 a, 400 b. In some embodiments, release actuators 650 a, 650 b are positioned on or accessible from a point on legs 400 a, 400 b proximate lateral supports 640 a, 640 b. Exemplary release actuators 650 a, 650 b (FIGS. 3A-3D) are positioned on an internal facing side of a respective leg 400 a, 400 b.
In other embodiments, release actuators 650 a, 650 b may be positioned remotely from a corresponding locking mechanism 620 and rotator 610. For example, release actuators 650 a, 650 b may be positioned on an external facing side of a respective leg 400 a, 400 b, optionally opposite lateral supports 640 a, 640 b. Such release actuators 650 a, 650 b may be operably connected remotely to corresponding locking mechanisms 620 a, 620 b. Remotely positioned release actuators 650 a, 650 b may comprise a ramp or other mechanical feature to actuate the locking mechanism 620.
Release actuators 650 a, 650 b may be in the form of a button, for example, a press button. Actuation of the release actuators 650 a, 650 b may comprise pressing the button. In some embodiments, the release actuators 650 a, 650 b may comprise a lever, latch, or slide button. Actuation of the release actuators 650 a, 650 b may comprise lowering or pulling on the lever, latch, or slide button. In some embodiments, the release actuators 650 a, 650 b may comprise a screw or knob. Actuation of the release actuators 650 a, 650 b may comprise twisting the screw or knob. Other release actuators 650 a, 650 b may be used. In some embodiments, the release actuator 650 a, 650 b becomes activated (e.g., button pops out or lever is raised or lowered) when the locking mechanism 620 a, 620 b is enabled, to indicate to a user that the locking mechanism 620 a, 620 b is properly activated.
The mechanism of one exemplary release actuator 650 a is shown in FIG. 5 . The release actuator 650 a may be operably connected to locking mechanism 620. In the embodiment of FIG. 5 , release actuator 650 a is mechanically connected to locking mechanism peg 620. In particular, release actuator 650 a and locking mechanism peg 620 are formed of a single piece. The release actuator 650 a and locking mechanism peg 620 assembly is housed within the rotator 610 housing. The release actuator 650 a may be spring-loaded. In use, the compression spring may hold the release actuator 650 a in the engaged position (popped up) and locking mechanism peg 620 in the extended or locked position, engaging the corresponding locking mechanism slot 622 and preventing rotation of the rotator plate 612 about rotator 610. Pressing the release actuator 650 a button to compress the spring may disengage the release actuator 650 a, retracting the locking mechanism peg 620 into the unlocked position. The locking mechanism peg 620 may disengage the corresponding locking mechanism slot 622, allowing rotation of the rotator plate 612 about the rotator ring 610.
In some embodiments, for example, as shown in FIGS. 4A-4B, the lateral support 640 a, 640 b may comprise an access window for the corresponding release actuator 650 a, 650 b. When the lateral support 640 a, 640 b is assembled adjacent the legs 400 a, 400 b (for example, adjacent the rotator 610), the release actuator 650 a, 650 b may be accessible via the access window of the lateral support 640 a, 640 b.
It should be noted that although FIGS. 4A-4B and 5 show rotator plate 612 fixed to lateral support 640 a and rotator ring 610 fixed to leg 400 a, in some embodiments, the rotator plate 612 may be fixed to leg 400 a and rotator ring 610 may be fixed to lateral support 640 a. Additionally, release actuator 650 a and/or locking mechanism 620 may be fixed to lateral support 640 a. Thus, in some embodiments, locking mechanism slot 622 may be positioned on leg 400 a.
Exemplary use of the footrest 600 is shown in FIGS. 3A-3D. As shown in FIG. 3A, a user may actuate the release actuators 650 a, 650 b to enable rotation of the rotator 610. In the second (higher) position shown in FIG. 3A, planar surface 634 is facing up. As shown in FIGS. 3B-3C, the user may drive the footrest 600 to a desired position by rotation of the rotator 610. As shown in FIG. 3D, in the first (lower) position, the planar surface 632 is facing up. The user may actuate the locking mechanism 620 to lock the footrest 600 in the desired position for foot support. The locking mechanism 620 may be automatically enabled when the footrest 600 is rotated into a pre-set position (FIG. 3D). The release actuators 650 a, 650 b may reset (for example, pop out) to indicate that the locking mechanism 620 is enabled.
In some embodiments, the rotator 610 is configured to rotate in one direction automatically. For example, the rotator 610 may rotate upwards or downwards automatically upon actuation of the release actuators 650 a, 650 b. Thus, in some embodiments, the rotator 610 may comprise a drive shaft. In some embodiments, the rotator 610 may be allowed to rotate by gravity. The rotator 610 may comprise a damper to reduce motion due to gravity. In other embodiments, the rotator 610 is substantially stationary unless rotation is driven by a user. The rotator 610 may comprise a damper to inhibit motion due to gravity.
In some embodiments, the footrest 600 may provide tactical, visual, and/or auditory feedback to the user indicating motion along the arc of rotation. For instance, the footrest 600 may click or vibrate to indicate motion. The feedback may be provided by a structural feature of the rotator 610. In some embodiments, the feedback may indicate the location of a pre-selected position for foot support or storage. Feedback may be beneficial in embodiments in which the locking mechanism 620 is only able to lock the footrest 600 in a pre-selected position. However, feedback may be provided in embodiments in which the locking mechanism 620 is able to lock the footrest 600 in any position along the arc of rotation.

The first waist strap 214 and the second waist strap 224 may be joined or extend behind the waist, hips, or back of the child, each waist strap emerging from behind the child to extend across a corresponding hip of the child, when the child is seated.
The harness 200 may have one or more crotch straps 230 (FIG. 10 ). The crotch strap 230 may be positioned to extend between the legs of the child. The crotch strap 230 may have a length selected to extend until a crotch area of the child, when seated. In some embodiments, the crotch strap 230 may comprise a buckle 240. Thus, the harness 200 or highchair may comprise a buckle 240. The buckle 240 may be dimensioned to mate with one or more corresponding latch 215, 225 of the harness 200. The buckle 240 may comprise a latch release mechanism, for example, a button or other mechanical actuator, for releasing the one or more latch 215, 225.
In some embodiments, the harness 200 may be a five-point harness. In a five-point harness, the first and second shoulder strap 210, 220, first and second waist strap 214, 224, and crotch strap 230 may be designed and positioned to meet at a single point. The meeting point of the straps may be at or near a crotch area of the child. The meeting point may be selected to avoid the chest or abdomen of the child. The five-point harness may typically comprise one or more buckles 240 at the meeting point to receive at least one latch 215, 225 securing the straps. In some embodiments, the five-point harness may be formed by two or three straps. One exemplary five-point harness is shown in FIGS. 11A-11B. The exemplary five-point harness is formed by first shoulder strap 210, second shoulder strap 220, and crotch strap 230. As shown in FIGS. 11A-11B, the first shoulder strap 210 and the second shoulder strap 220 may each comprise a corresponding latch, 215, 225. Upon buckling the latch 215, 225 in a centrally positioned buckle 240, the first shoulder strap 210 and second shoulder strap 220 may each form a corresponding shoulder strap portion 212, 222 and a waist strap portion 214, 224, as shown in the buckled view of FIG. 11B. Shoulder strap portions 212, 222 are formed of the same strap and come together at the upper backrest. Waist strap portions 214, 224 join the first shoulder strap portion 212 to the second shoulder strap portion 222 on an opposite end, along the lower backrest. Accordingly, one or two shoulder straps 210, 220 and a crotch strap 230 may form a five-point harness when buckled.
The shoulder strap 210, 220 may be extendable to accommodate a growing child. The seat 100 may have a harness locking mechanism configured to lock the shoulder strap 210, 220 in a desired position, for example, to have a desired length, to accommodate the child.
