Description

[Technical Field]

[0001] This application claims priority to (i) U.S. Provisional Patent Application No. 63 / 181,577, filed April 29, 2021, (ii) U.S. Provisional Patent Application No. 63 / 221,971, filed July 15, 2021, and (iii) U.S. Provisional Patent Application No. 63 / 255,895, filed October 14, 2021, the disclosures of all of which are incorporated by reference herein as if set forth in their entireties.

[0002] The present disclosure relates generally to child car seats, and more particularly to child car seats having multi-use configurations, reclining configurations, and crash safety features. [Background technology]

[0003] Some child car seats currently on the market have multi-use configurations that allow continued use as the child grows. For example, some child car seats can be used in one or more of the following configurations: (1) a rear-facing reclining configuration for toddlers, (2) a forward-facing reclining configuration for toddlers, (3) a forward-facing high-back booster configuration for children weighing, for example, between 40 and 100 pounds, and (4) a forward-facing backless booster configuration for children weighing, for example, between 40 and 120 pounds. Summary of the Invention

[0004] In one example, a child car seat includes a body and a booster seat. The body includes a seat back having a first side wall and a second side wall spaced apart to define a space for a child's upper body therebetween. The booster seat is configured to be removably attached to the body. The booster seat includes first and second arms spaced apart from each other and a seating surface between the first and second arms. The first arm is configured to be removably attached to the first side wall at an interface between the first arm and the first side wall. The second arm and the second side wall can similarly be removably attached to each other. Various connection structures or interfaces can be provided between the side walls and the arms. The connection interface defined by the side walls of the body can increase the structural rigidity of the child car seat.

[0005] In another example, a child car seat includes a main body and a booster seat. The main body includes a seat back and at least one attachment member extending from the seat back. The booster seat includes a seating surface, a recess below the seating surface configured to receive the at least one attachment member, and at least one leg extending downward from the seating surface and retracting into the recess at a rear end of the seating surface. The at least one leg is configured to support the rear end of the seating surface when the booster seat is detached from the at least one attachment member. Based on this configuration, the booster seat can be used in a variety of situations that do not require attachment or installation to a child car seat. For example, the booster seat can be used as a standalone seat for a child or can be installed on the seating surface of a chair or seat booth.

[0006] In yet another example, a child car seat includes a body and a booster seat. The body includes a seat back and at least one attachment member extending in a forward direction from the seat back. The body defines at least one engagement surface. The booster seat is configured to be removably attached to the body. The booster seat includes a release latch having an engagement surface and an actuation surface. The engagement surface is configured to releasably engage with the engagement surface of the body to secure the booster seat and the body together. The actuation surface can be located on an exterior surface or a front surface of the booster seat. The actuation surface can be provided as a push button or other type of actuator.

[0007] In yet another example, a child car seat includes a main body, a booster seat, and a harness. The main body includes a seat back and at least one attachment member extending from the seat back. The booster seat has a seating surface. The booster seat is configured to be connected to the at least one attachment member such that the seating surface is positioned above the at least one attachment member. The booster seat has a pair of lap belt openings extending to a rear end of the booster seat. The harness includes a crotch buckle and first and second straps having first and second lap belt sections, respectively, configured to rest on the child's laps. The harness may include a reinforcement member attached to each of the first and second lap belt sections and extending from below the seating surface, through a corresponding one of the lap belt openings, and above the seating surface.

[0008] In yet another example, a child car seat includes a body, a seating surface, and a reclining foot. The body includes a seat back, and the seating surface extends forward from the seat back. The reclining foot has a front end defining an engagement surface configured to engage with the vehicle seat and a rear end positioned rearward of the front end. The rear end is coupled to the body such that the reclining foot is configured to pivot relative to the body about a pivot axis to transition the body between at least one reclined position and at least one inclined position. The rear end has a rigid portion not configured to engage with the vehicle seat (i.e., the rigid portion can be positioned above the vehicle seat). The reclining foot includes a deformable body attached to the rigid portion of the reclining foot. The deformable body is configured to engage with the vehicle seat and deform with a force less than that required to deform the rigid portion, thereby aiding in energy absorption during a collision event.

[0009] Various other configurations of child car seats are disclosed herein.

[0010] The following description of exemplary embodiments will be better understood when read in conjunction with the accompanying drawings, it being understood that potential embodiments of the disclosed systems and methods are not limited to those shown in the drawings.

[0012] 1 and 2, a child safety seat 10 (also known as a child car seat) of the present disclosure generally comprises a body 12 and a booster seat 300 configured to be removably attached to the body. The body 12 has a seat back 100 and at least one attachment member 200 (shown in FIG. 4A) extending from and attached to the seat back 100. The attachment member 200 may form the bottom or base of the child safety seat 10.

[0013] The booster seat 300 and the attachment member 200 are configured to be removably coupled to one another. In some examples, the attachment member 200 can define a seat extending forward from the seat back 100. In other examples, the attachment member 200 can define at least one protrusion, such as a rod, bar, or block of material, extending forward from the seat back 100 and configured to be removably attached to the booster seat 300. The child safety seat 10 can include at least one seat cover (not shown) that covers the back surface 104 (shown in FIG. 4A ) of the seat back 100 and the seating surface of the booster seat 300. As described in more detail below, the body 12 and the booster seat 300 can include interlocking features to improve the structural rigidity of the child safety seat 10.

[0014] 1 and 2 , in some examples, the child safety seat 10 may include a harness 400 including a first strap 402, a second strap 404, and a crotch buckle 406. In such examples, the child safety seat 10 may be configured such that when the booster seat 300 is coupled to the body 12, the crotch buckle 406 is positioned above the seating surface 302 of the booster seat 300 and is removably secured to the first and second straps 402, 404.

[0015] Additionally or alternatively, in some examples, the child safety seat 10 may comprise a reclining base 500. The reclining base 500 may be attached to the attachment member 200 such that the body 12 is configured to move relative to the reclining base 500 between an upright position (as shown at least in FIG. 2) and a reclined position (as shown at least in FIG. 3).

[0016] In some examples, the child safety seat 10 can be a high-back booster seat configured to be converted into a backless booster seat by removing the booster seat 300 from the body 12. In other examples, the child safety seat 10 can be a convertible car seat configured to be attached to a vehicle seat in a rear-facing orientation when in a reclined position and a forward-facing orientation when in an upright position, such as a 2-in-1 car seat, a 3-in-1 car seat, a 4-in-1 car seat, or an all-in-one car seat.

[0017] Next, features of the child safety seat 10 according to various examples of the present disclosure will be described in more detail. More specifically, referring to FIGS. 1 and 2 , the body 12 may have a front end 14 and a rear end 16 that are offset from one another. The front and rear ends 14, 16 may be offset along a first direction D1 (which may correspond to the fore-aft direction when the child safety seat 10 is installed in a vehicle). The body 12 may be configured so that, when a child is properly seated in the child safety seat 10, the child faces in a direction from the rear end 16 to the front end 14. The body 12 may have an upper end 18 and a lower end 20 that are offset from one another. The upper end 18 and the lower end 20 may be offset along a second direction D2 that is perpendicular to the first direction D1 (which may correspond to the vertical direction when the child safety seat 10 is installed in a vehicle). The body 12 may be configured so that, when a child is properly seated in the child safety seat 10, the child's head is positioned closer to the upper end 18 than to the lower end 20. The body 12 may be configured with a first side 22 and a second side 24 that are offset from one another. The first and second sides 22, 24 may be offset along a third direction D3 (which may correspond to a lateral direction when the child safety seat 10 is installed in a vehicle) that is perpendicular to both the first direction D1 and the second direction D2. The body 12 may be configured such that when a child is seated in the child safety seat 10, the child's arms are adjacent to the first and second sides 22, 24, respectively.

[0018] 4A and 4B , the seat back 100 includes a seat back body 102. A backrest surface 104 is configured to support a child's back when the child is seated in the child safety seat 10. The backrest surface 104 may extend generally along a second direction D2 and a third direction D3. The seat back 100 may include a headrest 150. The headrest 150 may be attached to or integrated with the seat back body 102. In some embodiments, the headrest 150 may be adjustable relative to the seat back body 102 along the second direction D2 between an extended position and a retracted position.

[0019] The seat back 100 may be comprised of a pair of side walls 106(1) and 106(2) spaced apart from one another along a third direction D3. The seat back surface 104 may be disposed between the side walls 106(1) and 106(2). The side walls 106(1) and 106(2) may extend from the seat back surface 104 along the first direction D1 and define a space therebetween that is dimensioned to receive a child's upper body. Each side wall 106(1), 106(2) may define a belt guide opening 107 therein that is configured to receive at least a portion of a vehicle restraint for securing the body 12 in a forward-facing position (i.e., facing forward of the vehicle).

[0020] The first sidewall 106(1) can be configured to couple (connect) to the first arm 316(1) (shown in FIG. 5 ) of the booster seat 300 at an interface between the first sidewall 106(1) and the first arm 316(1). In some examples, the coupling between the first sidewall 106(1) and the first arm 316(1) can limit or prevent inward or outward deflection of the first sidewall 106(1) along the third direction D3. Similarly, in some examples, the second sidewall 106(2) can be configured to couple to the second arm 316(2) (shown in FIG. 5 ) of the booster seat 300 at an interface between the second sidewall 106(2) and the second arm 316(2). In one example, the interface between the sidewalls 106(1), 106(2) and the arms 316(1), 316(2) may be provided via matching or complementary profiles of these components. For example, the sidewalls 106(1), 106(2) may each define a curved recess or pocket, and the arms 316(1), 316(2) may each have a corresponding curved protrusion or extension configured to rest or be received within the curved recess or pocket of the sidewalls 106(1), 106(2). In some examples, the bond between the second sidewall 106(2) and the second arm 316(2) may limit or prevent the second sidewall 106(2) from flexing inward or outward along the third direction D3. The connection between side walls 106(1), 106(2) and arms 316(1), 316(2) can generally limit or prevent (i) inward deflection of the arms toward the space sized to support a child, or (ii) outward deflection of the arms away from the space sized to support a child.

[0021] As shown in FIG. 4A , each side wall 106(1) and 106(2) may have an upper end 106a and a lower end 106b spaced apart from one another along the second direction D2. Each lower end 106b may be positioned adjacent to a corresponding arm 316(1), 316(2) (shown in FIG. 5 ) of the booster seat 300 when the booster seat 300 is coupled to the body 12. In some examples, each lower end 106b may define a surface that faces the corresponding arm 316(1), 316(2). At least one lower end 106b, and preferably each lower end 106b, is configured to couple to the corresponding arm 316(1), 316(2) of the booster seat 300. For example, each bottom end 106b can be configured to directly couple to a corresponding arm 316(1), 316(2) of the booster seat 300 such that the bottom end 106b contacts the arm 316(1), 316(2).

[0022] At least one lower end 106b, and preferably each lower end 106b, can include a first connector 108 configured to couple to a second connector of a corresponding arm 316(1), 316(2) of the booster seat 300. Figures 4A and 4B show an example in which each first connector 108 is a protrusion or rib, and each second connector (320(1), 320(2) in Figure 6A) of the booster seat 300 is an opening or pocket configured to receive a corresponding one of the first connectors 108 of the body 12 therein.

[0023] Each first connector 108 can extend downward from the lower end 106b of one of the side walls 106(1), 106(2). Additionally or alternatively, each first connector 108 can extend forward from the lower end 106b of one of the side walls 106(1), 106(2). In some examples, each first connector 108 can extend from the lower end 106b of one of the side walls 106(1), 106(2) to the attachment member 200 such that the first connector 108 is attached to both the lower end 106b of one of the side walls 106(1), 106(2) and the attachment member 200. Thus, the first connector 108 can be formed as a connecting rib or structure between the lower end 106b of the side walls 106(1), 106(2) and the attachment member 200. In such an example, each first connector 108 may also function as a stiffener to limit or prevent bending of the attachment member 200 relative to the seat back 100 in a plane extending along the first and second directions D1, D2. In one configuration, the main body 12 includes a male connector and the booster seat 300 includes a female connector. It will be understood that in alternative examples, other configurations of the connectors on both the main body 12 and the booster seat 300 are possible. For example, each first connector may define an opening and each second connector may define a protrusion configured to be received by a corresponding one of the first connectors.

[0024] The seat back 100 can be attached to the attachment member 200 adjacent the lower end 20. In some examples, the seat back 100 can be fixedly attached to the attachment member 200. For example, the seat back 100 can be fixedly positioned on the attachment member 200 so that movement of the seat back 100 in any direction causes a corresponding movement of the attachment member 200. The attachment member 200 can be a tube, bar, block, or other suitable shape. FIGS. 4A and 4B show an example in which the attachment member 200 is a single member having a plate-like shape whose width along the third direction D3 and whose depth along the first direction D1 are greater than the thickness of the attachment member 200 along the second direction D2. The attachment member 200 can be configured as a seat with a seating surface or without a seating surface. As an alternative (not shown), the main body 12 may have a pair of attachment members spaced apart from one another along the third direction D3, each formed as a bar or tube extending forward from the backrest surface 104 and each received in a recess in the booster seat 300.

[0025] The attachment member 200 may be preferably formed from a highly rigid material and may be attached to the seat back 100 in a manner that limits or prevents flexing of the attachment member 200 relative to the seat back 100 in a plane extending along the first direction D1 and the second direction D2. Thus, the attachment member 200 and the seat back 100 may be attached to each other so that the seating surface and the backrest surface 104 of the booster seat 300 do not move toward or away from each other. The attachment member 200 may extend from the seat back main body 102 adjacent the lower end 20, thereby defining a protrusion from the seat back main body 102. For example, the attachment member 200 may extend from the seat back main body 102 along a direction extending from the rear end 16 toward the front end 14. The attachment member 200 may be configured to be removably received in a recess 324 (shown in FIGS. 6A and 6B ) of the booster seat 300. In other words, the attachment member 200 can be configured to slide within the recess 324 beneath the booster 300 .

[0026] As shown in FIGS. 4A and 4B , the attachment member 200 may include a first side 202 and a second side 204 spaced apart from each other along the third direction D3. The attachment member 200 may include a front end 206 and a rear end 208 spaced apart from each other along the first direction D1. The rear end 208 may be attached to the seat back 100. The attachment member 200 may include an upper end 214. The upper end 214 may be covered by the booster seat 300 when the booster seat 300 is coupled to the attachment member 200. In some examples, the upper end 214 may define a seating surface, while in other examples, as shown in FIGS. 4A and 4B , the upper end 214 may not have a seating surface.

[0027] At least one of the first side 202 and the second side 204 can define at least one engagement surface 210 configured to engage with a corresponding engagement surface 326 defined on the booster seat 300 to guide movement of the booster seat 300 toward the attachment member 200 when the booster seat 300 is coupled to the attachment member 200 (e.g., when the booster seat 300 and the attachment member 200 are aligned with each other). In one example, each engagement surface 210 can be angled upward to extend along a forward direction. The direction of this angle can be varied, as will be understood by one of ordinary skill in the art.

[0028] The engagement surfaces 210, 326 can engage with one another (i.e., directly contact one another) to align the main body 12 and the booster seat 300 with one another when the main body 12 and the booster seat 300 are engaged with one another. Additionally or alternatively, the engagement surfaces 210, 326 can engage with one another to prevent relative movement between the main body 12 and the booster seat 300 along a direction perpendicular to the engagement surfaces 210, 326. The engagement surfaces 210, 326 can engage with one another to prevent relative movement between the main body 12 and the booster seat 300 along the first direction D1. In one example, as shown, at least one of the first and second side surfaces 202, 204 can define at least one protrusion 212 that includes the engagement surface 210. The at least one protrusion 212 is configured to be received in at least one opening 328 in the booster seat 300 that defines the at least one engagement surface 326. In this configuration, the protrusions 212 are male engaging members and the openings 328 are female engaging members. In an alternative example (not shown), at least one of the first and second sides 202, 204 can define at least one opening (i.e., female engaging member) configured to receive at least one protrusion (i.e., male engaging member) of the booster seat 300 that includes the engagement surface 210 and defines the at least one engagement surface 326.

[0029] The profiles of the engagement surface 210 and the engagement surface 326 may, in one example, be complementary to one another. As shown in FIGS. 4A and 4B, the engagement surface 210 may have a sloped or angled profile. Similarly, as shown in FIG. 6B, the engagement surface 326 may have a sloped or angled profile that is complementary to the sloped or angled profile of the engagement surface 210. One skilled in the art will appreciate that other profiles or mating configurations may be provided between the engagement surfaces 210, 326. In one example, the at least one protrusion 212 may include a pair of protrusions 212 defined on opposite sides of the upper end 214 of the attachment member 200. The pair of protrusions 212 may include a ramped body coupled to each one of the side surfaces 202, 204 of the attachment member 200. The pair of protrusions 212 may have a relatively low profile and may have a height that extends less than 50% of the overall height of the side surface 204. Those skilled in the art will understand, based on this disclosure, that this value may vary.

[0030] The at least one opening 328 may include a pair of openings defined on opposite sides of the booster seat 300. The openings 328 may be continuous with the recess 324, as shown in Figures 6A and 6B.

[0031] Referring to FIG. 8A, each side of the underside of the booster seat 300′ can include a pair of openings 328a, 328b and a pair of engagement surfaces 326a, 326b. Similarly, the main body 12′ can include two corresponding pairs of protrusions 212a, 212b and engagement surfaces 210a, 210b. Those skilled in the art will understand that while only one seat of the openings 328a, 328b, protrusions 212a, 212b, and engagement surfaces 210a, 210b, 326a, 326b pairs is shown for illustrative purposes, each side of the booster seat 300′ and the main body 12′ can include the features shown in FIG. 8A. FIG. 8B further illustrates the underside of the booster seat 300′ in an unattached state.

[0032] The interface between the engagement surfaces 210, 326 provides an additional safety feature by preventing the booster seat and main body from separating from each other in the event of an unintended impact or collision. Increasing the amount of engagement or interface, such as by providing multiple engagement surfaces 210a, 210b, 326a, 326b in Figures 8A and 8B, can further prevent inadvertent separation of the booster seat and main body.

[0033] As shown in at least FIG. 1 , the child safety seat 10 may include a harness 400 for securing a child in the child safety seat 10. The harness 400 may include a crotch strap 408. The crotch strap 408 may include a crotch buckle 406 and webbing 410. The harness 400 may include a first strap 402 and a second strap 404 configured to selectively secure to the crotch buckle 406. The first strap 402 may include a lap belt portion 402a configured to rest on the child's lap and / or a shoulder belt portion 402b configured to rest on the child's shoulder. The first strap 402 may include an end that is attached to the main body 12. For example, the first strap 402 may be attached to the attachment member 200 of the main body 12. Similarly, the second strap 404 may include a lap belt portion 404a configured to rest on the child's lap and / or a shoulder belt portion 404b configured to rest on the child's shoulder. The second strap 404 can have an end that is attached to the main body 12. For example, the second strap 404 can be attached to the attachment member 200 of the main body 12. The shoulder belt portions 402b, 404b may be repositionable for children of different sizes. For example, the top ends of the shoulder belt portions 402b, 404b can be higher for taller children and lower for shorter children. Thus, the shoulder belt portions 402b, 404b can have an uppermost position and a lowermost position. The attachment member 200 can include a harness release lever 218 (shown in FIG. 4A ) configured to be engaged by a user to release the harness 400, thereby allowing the harness 400 to be loosened for the child.

[0034] Each lap belt portion 402a, 404a may be coupled to the attachment member 200 in a position that is disposed below the seating surface 302 of the booster seat 300 when the booster seat 300 is coupled to the attachment member 200. While FIGS. 15 and 16 illustrate this feature for the lap belt portion 402a, one skilled in the art will appreciate that the same configuration may be provided for the other lap belt portion 404a. The harness 400 may include a reinforcement 403 for each lap belt portion 402a, 404a that is attached to the lap belt portion 402a, 404a as the lap belt portion 402a, 404a extends from below the seating surface 302, through the lap belt opening 334 of the booster seat 300, and above the seating surface 302. The reinforcement 403 may be any suitable reinforcement that reinforces the lower end of the lap belt portion 402a, 404a. For example, the reinforcement 403 can be a webbing that is sewn or otherwise secured to the lower ends of the lap belt portions 402a, 404a. In some examples, the child safety seat 10 can include an anchor 220, such as a rod or other protrusion, that is positioned below the seating surface 302. The anchor 220, in one example, can be located inside the attachment member 200. In one configuration, the lap belt portions 402a, 404a can be looped around the anchor 220 and sewn back on themselves to be bonded to the anchor 220, as shown in FIG. 16 . In other examples, the reinforcement 403 can be a coating applied to the lower ends of the lap belt portions 402a, 404a or a sheath that surrounds the lower ends of the lap belt portions 402a, 404a. The reinforcement 403 allows the lower ends of the lap belt portions 402a, 404a to stand upright when the booster seat 300 is coupled to the attachment member 200 so that the lower ends of the lap belt portions 402a, 404a are easily received in the lap belt openings 334 of the booster seat 300.

[0035] Each stiffener 403 may optionally define a stop 403a configured to interfere with the latch 412 of the harness 400 to prevent the latch 412 from moving all the way to the bottom of the lap belt portions 402a, 404a. The stop 403a may be located at the top of the stiffener 403. In one example, the stop 403a may be defined by an end of the stiffener 403, such as a loose end of the webbing, immediately above where the webbing is sewn to the lap belt portions 402a, 404a. A latch 412 may be provided on each of the straps 402, 404 and configured to secure the straps 402, 404 relative to the crotch buckle 406. The latch 412 may be releasably secured or fastened to the crotch buckle 406 to secure the child in the child safety seat 10.

[0036] 4A and 4B , the attachment member 200 can define a pocket 216 therein. The pocket 216 can be configured to receive and store the crotch buckle 406 when the crotch buckle 406 is not being used to secure a child to the child safety seat 10. For example, the crotch buckle 406 can be stored in the pocket 216 when the child safety seat 10 is used as a forward-facing booster seat without the harness 400. The webbing 410 of the crotch strap 408 can be attached to the attachment member 200 within the pocket 216. For example, the webbing 410 can be attached to an inner surface of the pocket 216. The inner surface can be, for example, a bottom or side surface of the pocket 216. In some examples, the pocket 216 can be configured such that the crotch buckle 406 protrudes above the pocket 216 when the crotch buckle 406 is received therein. This may allow the crotch buckle 406 to be more accessible to a user through the crotch buckle opening 332 (shown in FIG. 5 ) of the booster seat 300 when the booster seat 300 is coupled to the attachment member 200. Alternatively, the pocket 216 may include a cover that can be closed to store the crotch buckle 406 when not in use.

[0037] 5, 6A, and 6B, the booster seat 300 may have a front end 300a and a rear end 300b offset from each other along a first direction D1. The booster seat 300 may have an upper end 300c and a lower end 300d offset from each other along a second direction D2. The booster seat 300 may have a first side 300e and a second side 300f offset from each other along a third direction D3. The booster seat 300 may include a seating surface 302. The seating surface 302 may extend from the front end 300a toward the rear end 300b. The seating surface 302 may at least partially define a receiving space 304 configured to receive a child's lower body. The booster seat 300 may define at least one recess 324 therein configured to receive the attachment member 200 of the main body 12. At least one recess 324 can extend toward the front end 300a and into the rear end 300b. In some embodiments, at least one recess 324 can also extend toward the seating surface 302 at the bottom end 300d.

[0038] Arms 316(1), 316(2) of booster seat 300 can optionally define lap belt guides (also referred to herein as “forward lap belt guides”) configured to position a lap belt portion of a vehicle restraint when body 12 is in a forward-facing position (i.e., facing the front of the vehicle). Arms 316(1) and 316(2) can be spaced apart from one another along third direction D3. Each arm 316(1) and 316(2) can extend upwardly from seating surface 302.

[0039] Each arm 316(1), 316(2) can define a recess or opening 316a configured to receive a lap belt portion of a vehicle restraint, such as a seat belt. In one example, as shown, the recess or opening 316a can open toward the front end of the arms 316(1), 316(2) such that the arms 316(1), 316(2) have an inverted "L" shape. Thus, each arm 316(1), 316(2) can have a first end 316b that is attached to the body of the booster seat 300 and a second end 316c that is free from attachment to the booster seat body. The second end 316c can be spaced from the body of the booster seat 300 to define a space therebetween for receiving the vehicle restraint. Arms 316(1), 316(2) may be configured to receive a vehicle restraint belt therein, such as a vehicle seat belt or a separate restraint belt, for mounting child safety seat 10 to a vehicle seat in a forward-facing position. Arms 316(1), 316(2) may also define a receiving space 304 for a child between them.

[0040] At least one of the first and second arms 316(1), 316(2) can be positioned adjacent to the lower end 106b of the corresponding side wall 106(1), 106(2) of the body 12 when the booster seat 300 is coupled to the body 12. In some examples, each of the first and second arms 316(1), 316(2) can define a surface that faces the lower end 106b of the corresponding side wall 106(1), 106(2). At least one of the first and second arms 316(1), 316(2), and preferably both, can be configured to be attached to the lower end 106b of the corresponding side wall 106(1), 106(2). For example, at least one of the first and second arms 316(1), 316(2), and preferably both, can be configured to be directly attached to the corresponding one of the side walls 106(1), 106(2) of the body 12.

[0041] 5, 6A, and 6B, additionally or alternatively, booster seat 300 may include at least one pair of armrests 318(1), 318(2). Armrests 318(1), 318(2) may be spaced apart from one another along third direction D3. Each armrest 318(1), 318(2) may be spaced apart from a respective one of arms 316(1), 316(2) along first direction D1. Receiving space 304 may be defined between armrests 318(1), 318(2). In some examples, booster seat 300 may include at least one object holder, such as a pair of object holders 330(1), 330(2). At least one of object holders 330(1), 330(2) may be a cup holder. In some examples, at least one of object holders 330(1), 330(2) can be an object holder other than a cup holder, such as a snack holder. Each object holder 330(1), 330(2) can be positioned in front of a corresponding one of armrests 318(1), 318(2) and / or a corresponding one of arms 316(1), 316(2). The perimeter of each of recesses or openings 316a can be partially defined by armrests 318(1), 318(2) and arms 316(1), 316(2).

[0042] At least one, and preferably both, of the first and second arms 316(1), 316(2) can define a second coupler 320(1), 320(2) configured to couple to a first coupler 108 on a corresponding side wall 106(1), 106(2) of the body 12. FIG. 6A shows an example in which each second coupler 320(1), 320(2) defines an opening, and each first coupler 108 on the body 12 is a protrusion configured to be received in a corresponding one of the couplers 320(1), 320(2) on the booster seat 300. Each second coupler 320(1), 320(2) can extend into a corresponding one of the first and second arms 316(1), 316(2). For example, each second coupler 320(1), 320(2) can extend onto a surface of a corresponding one of the first and second arms 316(1), 316(2), where the surface faces one of the side walls 106(1), 106(2). Each second coupler 320(1), 320(2) can extend along the first direction D1 to the rear end of the corresponding one of the first and second arms 316(1), 316(2). Additionally or alternatively, each second coupler 320(1), 320(2) can extend into the corresponding one of the first and second arms 316(1), 316(2) along the second direction D2. It will be understood that in alternative embodiments, each second coupler 320(1), 320(2) can have other configurations. For example, each second coupler 320(1), 320(2) of booster seat 300 may define a protrusion, and each first coupler 108 of body 12 may define an opening configured to be received by a corresponding one of second couplers 320(1), 320(2).

[0043] Another exemplary configuration for coupling booster seat 300'' to body 12 is shown in Figures 9, 10, and 11. In this example, each first coupler 108' (formed as a protrusion in this example) is configured to extend in a selected direction D from a corresponding one of arms 316(1)', 316(2)' to a corresponding one of side walls 106(1)', 106(2)'. Sand / or along the first direction D1. In other words, each first coupler 108' and corresponding second coupler 320(1)', 320(2)' has a shape configured to prevent the first coupler 108' from being detached from the corresponding second coupler 320(1)', 320(2)' along the first direction D1. In other words, each first coupler 108' and corresponding second coupler 320(1)', 320(2)' has a shape configured to prevent the corresponding one of the arms 316(1)', 316(2)' from being detached from the corresponding second coupler 320(1)', 320(2)' along the first direction D1. S For example, each first coupler 108' may have a first portion 108a' and a second portion 108b' that are oriented in a selected direction D. S The second portion 108b' may have a second portion 108b' disposed outside the first portion 108a' along the selected direction D. S The first coupler 108' may have a cross-sectional dimension in a plane perpendicular to the first portion 108a', which cross-sectional dimension is greater than the cross-sectional dimension of the first portion 108a'. The first portion 108a' may be considered a neck, and the second portion 108b' may be considered a head. The head may be configured to be retained within the corresponding second coupler 320(1)', 320(2)' to prevent the corresponding arms 316(1)', 316(2)' and side walls 106(1)', 106(2)' from being pulled apart from one another. The first coupler 108' may have a T-shape in the cross-sectional plane, although other shapes are contemplated within the scope of the present disclosure.

[0044] Each second coupler 320(1)', 320(2)' has a first portion 320a' and a selected direction D S and a second portion 320a' spaced inwardly from the first portion 320a' along the selected direction D. The first portion 320a' of the opening may be configured to receive the first portion 108a' of the first coupler 108', and the second portion 320a' of the opening may be configured to receive the second portion 108b' of the first coupler 108'. The second portion 320a' of the opening may be configured to receive the second portion 108b' of the first coupler 108'. S The first portion 320a' of the opening can have a cross-sectional dimension in a plane perpendicular to the selected direction D, which cross-sectional dimension is greater than the cross-sectional dimension of the first portion 320a' of the opening. SEach second coupler 320(1)', 320(2)' may have a cross-sectional dimension in a plane perpendicular to the first and second portions 108a', 108b', which is greater than the cross-sectional dimension of the first portion 108a' (e.g., neck) of the first coupler 108' and less than the cross-sectional dimension of the second portion 108b' of the coupler 108'. Each second coupler 320(1)', 320(2)' may have a T-shape in cross section, although other shapes are contemplated within the scope of this disclosure. Each second coupler 320(1)', 320(2)' may also have a third portion 320b' that is open to the first and second portions. The third portion 320b' may be oriented in a selected direction D. S The first coupler 108' may have a cross-sectional dimension in a plane perpendicular to the third portion 320b', which is larger than a cross-sectional dimension of the second portion 108b' (e.g., head) of the first coupler 108' to allow the first coupler 108' to be inserted through the third portion 320b' and into the first portion 320a' of the second coupler 320(1)', 320(2)'. The shapes or profiles of the first coupler 108' and the second couplers 320(1)', 320(2)' may be complementary to one another.

[0045] In some examples, the booster seat 300 can define first and second belt guides 322(1), 322(2) (also referred to herein as “rear-facing belt guides”) configured to position at least a portion of a vehicle restraint when the body 12 is in a rear-facing position (i.e., facing the rear of the vehicle). The first rear-facing belt guide 322(1) can extend through a first side of the booster seat 300, and the second rear-facing belt guide 322(2) can extend through a second side of the booster seat 300. Thus, the first and second rear-facing belt guides 322(1), 322(2) can be spaced apart from one another along the third direction D3. The first and second rear-facing belt guides 322(1), 322(2) can be configured to receive a vehicle restraint belt therein, such as a vehicle seat belt or a separate restraint belt, for attaching the child safety seat 10 to a vehicle seat in a rear-facing position. When booster seat 300 is attached to body 12, first and second rearward facing belt guides 322(1), 322(2) can be positioned closer to front end 14 of body 12 than to rear end 16. First and second rearward facing belt guides 322(1), 322(2) can be spaced closer to front end 14 of body 12 than first and second arms 316(1), 316(2).

[0046] The booster seat 300 may include a first inner side surface 325(1) and a second inner side surface 325(2) spaced apart from one another along the third direction D3 and defined on the underside of the booster seat 300. A front surface 325(3) may extend between and connect the first and second inner side surfaces 325(1), 325(2). The first and second inner side surfaces 325(1), 325(2), together with the front surface 325(3), may partially define at least one recess 324 therebetween. At least one, and preferably both, of the first and second inner side surfaces 325(1), 325(2) may define at least one engagement surface 326 configured to engage with a corresponding engagement surface 210 of the body 12. In one example, each engagement surface 326 can be angled upward to extend along the forward direction. The engagement surfaces 210, 326 can engage with each other to align the body 12 and the booster seat 300 with each other when the body 12 and the booster seat 300 are coupled together. Additionally or alternatively, the engagement surfaces 210, 326 can engage with each other to prevent relative movement between the body 12 and the booster seat 300 along a direction perpendicular to the engagement surfaces 210, 326. The engagement surfaces 210, 326 can engage with each other to prevent relative movement between the body 12 and the booster seat 300 along the first direction D1. In one example, as shown, at least one, and preferably both, of the first and second inner sides 325(1), 325(2) can include at least one opening 328 defined by a corresponding one of the engagement surfaces 326, the at least one opening 328 configured to receive at least one protrusion 212 of the body 12. In an alternative example (not shown), at least one, and preferably both, of the first and second inner sides 325(1), 325(2) can define at least one protrusion defining a corresponding one of the engagement surfaces 326, the at least one protrusion configured to be received in at least one opening of the body 12.

[0047] 5, 6A, and 6B, the booster seat 300 can define a plurality of openings configured to interface with the harness 400. For example, the booster seat 300 can define a crotch buckle opening 332 extending through the seating surface 302. The crotch buckle opening 332 can open into the recess 324. The crotch buckle opening 332 can be at least partially aligned with the pocket 216 of the body 12 when the booster seat 300 is attached to the body 12, thereby allowing a user to pull the crotch buckle 406 from the pocket 216 and through the crotch buckle opening 332 such that the webbing 410 extends through the crotch buckle opening 332 and the crotch buckle 406 is positioned above the seating surface 302.

[0048] Additionally or alternatively, the booster seat 300 can define at least one lap belt opening 334, each configured to receive a lap belt portion 402a, 404a of one of the first and second straps 402, 404 therein. Each lap belt opening 334 can extend to the rear end of the booster seat 300. The lap belt openings 334 can be formed as slots extending into the seating surface 302. Additionally or alternatively, the booster seat 300 can define at least one opening 336 aligned with the harness release lever 218 to allow a user to access the harness release lever 218. The at least one opening 336 can be defined as an opening in the seating surface 302, preferably on the front end 300a of the booster seat 300.

[0049] The booster seat 300 may include at least one leg 342 extending downward from the seating surface 302 at the rear end of the booster seat 300. The at least one leg 342 may provide structural support to the rear end of the seating surface 302 when the booster seat 300 is used separately from the main body 12. The at least one leg 342 may be configured to engage a chair surface, ground surface, or other surface to provide stability and support for the booster seat 300. The at least one leg 342 may be formed on a cantilever portion 302a of the seating surface 302. The at least one leg 342 may be positioned between the lap belt openings 334. The attachment member 200 may include at least one opening 222 (labeled in FIG. 4B ) therein configured to receive at least a portion of the at least one leg 342 when the booster seat 300 is coupled to the attachment member 200. The at least one leg portion 342 and the at least one opening 222 can engage with each other to guide movement of the booster seat 300 toward the attachment member 200 when the booster seat 300 is coupled to the attachment member 200 (e.g., to align the booster seat 300 and the attachment member 200 with each other).

[0050] With reference to FIG. 7A, booster seat 300''' can include two legs 342a, 342b formed as fins or spaced apart protrusions defined on the underside of booster seat 300'''. The two legs 342a, 342b otherwise function similarly to at least one leg 342 described herein. With reference to FIG. 7B, booster seat 300'''' can include additional legs 342c, 342d formed as fins or spaced apart protrusions defined on the underside of booster seat 300'''' at different locations toward the rear end of booster seat 300''''.

[0051] 6A, 6B, and 14, the booster seat 300 may include at least one release latch 314 (shown in detail in FIG. 14) configured to selectively engage the main body 12 to secure the booster seat 300 and the main body 12 together. The release latch 314 may secure the booster seat 300 and the main body 12 together with respect to movement along at least one, and up to all, of a first direction D1, a second direction D2, and a third direction D3. The release latch 314 may be integrated into a portion of the booster seat 300. The booster seat 300 may include an actuation surface 338 for each release latch 314, the actuation surface 338 configured to be engaged by a user to unlatch the release latch 314, thereby allowing the booster seat 300 to be removed from the main body 12. In one example, the actuation surface 338 may be defined by an actuation button 340. The activation button 340 can be configured to be pressed into an exterior surface of the booster seat 300. For example, the activation button 340 can be pressed into the exterior side 301 a or front 301 b of the body 301 of the booster seat 300. In some examples, the booster seat 300 can include a pair of release latches 314 located on either side 300 e and 300 f of the booster seat 300.

[0052] As shown in Figure 14, each release latch 314 can include an engagement surface 314a configured to engage with an engagement surface on the main body 12 to secure the booster seat 300 and the main body 12 together for movement along at least one, and up to all, of the first direction D1, the second direction D2, and the third direction D3. While Figure 14 shows one example of a release latch 314, it will be understood that the release latch 314 can be implemented in any other suitable manner.

[0053] In one example, the release latch 314 can be comprised of a protrusion 314b defining an engagement surface 314a, and the body 12 can define a recess 317 (shown in FIG. 4D) that receives the protrusion 314b. The engagement surface 314a can be biased toward the body 12 by a spring 315 or other known biasing element. The release latch 314 can be configured such that when the actuation surface 338 is engaged by a user, the engagement surface 314a of the release latch 314 at least partially retracts into the booster seat 300 and disengages from the body 12.

[0054] The release latch 314 can have a first end 314c and a second end 314d. The first end 314c can define the surface 338. The second end 314d can define the engagement surface 314a. The release latch 314 can be pivotally coupled to the main body 301 of the booster seat 300 at a pivot axis A located between the first and second ends 314c, 314d of the release latch 314. The pivot axis A can extend along, for example, the second direction D2 or the third direction D3.

[0055] 12 and 13, in some examples, the child safety seat 10 can include a reclining base 500. The reclining base 500 can be configured to transition the child safety seat 10 between at least one upright position (e.g., FIGS. 2 and 12) and at least one reclined position (e.g., FIGS. 3 and 13). The reclining base 500 can have any suitable configuration. In some examples, the reclining base 500 can have at least one reclining foot 502, 504. In some such examples, the reclining base 500 can have a first reclining foot 502 and a second reclining foot 504. A description of one such reclining base is provided in U.S. Patent Publication No. 220 / 0223332, published July 16, 2020, the entire contents of which are incorporated herein by reference as if set forth in its entirety.

[0056] In an alternative example (not shown), body 12 can have a curved bottom surface, and reclining base 500 can be configured with a curved top surface to match the bottom surface of body 12. The bottom surface of body 12 can be configured to translate along the top surface of reclining base 500 to transition body 12 between at least one upright position and at least one reclined position.

[0057] Referring to FIG. 17 , the first reclining foot 502 may have a front end 502a and a rear end 502b. The front end 502a may define an engagement region 502c that defines a surface configured to engage with the vehicle seat 600 or another supporting surface or the ground when the seat is not installed in the vehicle. The rear end 502b may be disposed rearward of the front end 502a and the engagement region 502c. The engagement region 502c may be enlarged relative to the rear end 502b. For example, the engagement region 502c may have a width along the third direction D3 that is greater than the width of the rear end 502b. The engagement region 502c may be elongated along the third direction D3.

The first reclining foot 502 may be configured such that the front end 502a moves toward and swings away from the front end 14 of the main body 12 along the second direction D2.

[0058] The rear end 502b may include at least one coupler 502e configured to pivotally couple the first reclining foot 502 to the main body 12. The at least one coupler 502e may be any suitable coupler. In one example, the at least one coupler 502e may be a protrusion configured to be received in at least one opening in the main body 12. In another example (not shown), the at least one coupler 502e may be an opening configured to receive a protrusion in the main body 12. The rear end 502b may have at least one rigid portion 502d extending freely in a cantilevered manner from the engagement region 502c. For example, the rear end 502b may include a pair of rigid portions 502d offset from each other along the third direction D3 to define a space therebetween. Each rigid portion 502d may define an arm extending rearward from the front end 502a. Each rigid portion 502d can be configured not to engage the vehicle seat 600. Each rigid portion 502d can comprise at least one of the couplers 502e.

[0059] The recliner base 500 may include a recliner lock 506 and a recliner actuation 508. The recliner lock 506 may be configured to releasably lock the first recliner foot 502 in a plurality of different positions. The recliner actuation 508 may be configured to be engaged by a caregiver to transition the recliner lock 506 between a locked position, in which the position of the first recliner foot 502 is fixed relative to the body 12, and an unlocked position, in which the first recliner foot 502 is pivotable relative to the body 12. The recliner actuation 508 may define a push button or handle configured to be engaged by the caregiver. The recliner actuation 508 may be any suitable actuation, and the recliner lock 506 may be any suitable lock.

[0060] In one example, as shown, the recliner lock 506 can have at least one protrusion 506a, and the front end 502a of the first recliner foot 502 can have a surface defining at least one set of openings 502f configured to selectively receive the at least one protrusion 506a. As shown in FIG. 17 , the openings 502f can be defined in at least two parallel sets. Each set of openings 502f can include a series of openings 502f aligned with one another in the second direction D2. Each opening 502f in a set can correspond to a different position of the first recliner foot 502. In some examples, the recliner lock 506 can be comprised of multiple protrusions 506a offset from one another along the third direction D3, and the first recliner foot 502 can define multiple sets of openings 502f, each set offset from one another along the third direction D3. The recliner lock 506 may be biased to the locked position by a biasing element (not shown), such as a spring. The recliner lock 506 rotates about a pivot axis A between the locked and unlocked positions. L The pivot axis A can be configured to pivot about the pivot axis A. L can extend along a third direction D3. The recliner lock 506 can include a coupler 506b configured to be coupled to a portion of the first recliner foot 502, a portion of the body 12, or other structure.

[0061] The second recliner foot 504 can have a first end 504a and a second end 504b. The first end 504a can define an engagement area 504c that defines a surface configured to engage the vehicle seat 600 or other supporting surface or the ground when the seat is not installed in the vehicle. The second end 504b ... P2The first reclining foot 502 can be coupled to either the first reclining foot 502 or the main body 12 of the child seat 10 so as to be configured to pivot relative to the main body 12 about a first maximum angle (e.g., less than 90 degrees). The first reclining foot 502 can be configured to pivot to a first maximum angle (e.g., less than 90 degrees), and the second reclining foot 504 can be configured to pivot to a second maximum angle (e.g., greater than 90 degrees) that is greater than the first maximum angle. The second reclining foot 504 can be configured to pivot such that the first end 504a moves between a rearward-facing position and a forward-facing position. In some examples, the second reclining foot 504 can be configured to pivot without pivoting the first reclining foot 502.

[0062] The second end 504b connects the second reclining foot 504 to the main body 12 or the first reclining foot 502 (pivot axis A P2 The at least one coupler 504d may include at least one coupler 504d configured to pivotally couple to the first recliner foot 502 (about a center of gravity). The at least one coupler 504d may be any suitable coupler. In one example, the at least one coupler 504d may be a protrusion configured to be received in at least one opening 502g of the first recliner foot 502 or the body 12. For example, each opening 502g may be defined in the rigid portion 502d of the first recliner foot 502. In another example (not shown), the at least one coupler 504d may be an opening configured to receive a protrusion of the first recliner foot 502 or the body 12.

[0063] 18A through 18F, the child safety seat 10 can be attached to the vehicle seat 600 in a rearward-facing orientation (as shown in FIGS. 18A through 18C) or a forward-facing orientation (as shown in FIGS. 18D through 18F). In each orientation, the child safety seat 10 can be positioned in a number of different reclining positions. For example, in the rearward-facing orientation (rearward relative to the vehicle seat 600) shown in FIGS. 18A through 18C, the second reclining foot 504 can be pivoted to a forward-facing position (forward relative to the child safety seat 10), and the first reclining foot 502 can be pivoted to one of a number of different reclining positions. As shown in the orientations of FIGS. 18A through 18C, the first reclining foot 502 can rest on or rest on the second reclining foot 504 such that the first reclining foot 502 does not contact the vehicle seat 600. The child seat 10 can be reclined by pivoting the first reclining foot 502 away from the body 12, while the second reclining foot 504 remains in a forward-facing position.

[0064] In the forward-facing orientation (forward relative to the vehicle seat 600) shown in FIGS. 18D-18F, the second reclining foot 504 can be pivoted to a rearward-facing position (rearward relative to the child safety seat 10), and the first reclining foot 502 can be pivoted to one of a number of different reclining positions. As shown in the orientations of FIGS. 18D-18F, the second reclining foot 504 is pivoted so that the first reclining foot 502 rests on the vehicle seat 600 rather than on the second reclining foot 504. In the forward-facing position, the child safety seat 10 can be reclined by pivoting the first reclining foot 502 away from the body 12. In the configuration shown in FIGS. 18D-18F, both the first reclining foot 502 and the second reclining foot 504 rest on the vehicle seat 600. In one example, the second reclining foot 504 can be configured to engage the vehicle seat 600 regardless of the configuration or orientation of the child safety seat 10, while the first reclining foot 502 selectively engages the vehicle seat 600 depending on the orientation or configuration of the child safety seat 10.

[0065] 19, a side view of the position of a child safety seat 10 on a vehicle seat 600 during a vehicle accident, such as a frontal collision, is shown. As shown, during a collision, the child safety seat 10 rotates forward and downward. This causes the child safety seat 10 to compress the cushion 604 of the seat pan 602 until a force is applied by the front end 608 of the frame 606 of the vehicle seat 600 to at least one rigid portion 502d of the first reclining foot 502. This force may cause the rotation of the child safety seat 10 to stop prematurely, resulting in an undesirably high head injury criterion (HIC) value and / or an undesirably high thoracic G-force value as measured under Federal Motor Vehicle Safety Standard 213 (FMVSS 213).

[0066] To reduce the HIC value and / or thoracic G-force value, the child safety seat 10 may include at least one deformable body 510 that absorbs energy from an impact of the child safety seat 10 against the front end 608 of the vehicle seat frame 606. The at least one deformable body 510 may be formed on the underside of the attachment member 200. For example, each side 202, 204 of the attachment member 200 may define a deformable rib (not shown) extending from the bottom of the attachment member 200 and configured to deform in response to an impact from the frame 606 of the vehicle seat 600. However, the bottom of the attachment member 200 is smaller than would be required if the child safety seat 10 did not include the removable booster seat 300. As a result, the deformable rib extending from the bottom of the attachment member 200 is not tall enough to provide sufficient energy absorption during a vehicle accident.

[0067] Thus, for example, to provide sufficient energy absorption to meet FMVSS 213, at least one deformable body 510 can be affixed to at least one rigid portion 502d of the first reclining foot 502, such as to the underside of the at least one rigid portion 502d. In some examples, the at least one deformable body 510 can include first and second deformable bodies 510 secured to the first and second rigid portions 502d of the first reclining foot 502, respectively. In some examples, each of the at least one deformable body 510 can be a separate body coupled to a corresponding rigid portion 502d. For example, as shown in FIGS. 20 and 21, the deformable body 510 can be formed from a deformable material such as expanded polystyrene (EPS). The deformable body 510 can have a density less than that of the at least one rigid portion 502d. The deformable body 510 can be configured to engage with the vehicle seat 600 (e.g., the front end 608 of the frame 606) and deform with a lower force than the at least one rigid portion 502d. In other words, a first predetermined force can deform the deformable body 510, and a second predetermined force can deform the rigid portion 502d, the first predetermined force being less than the second predetermined force. In one example, the rigid portion 502d is more rigid than the deformable body 510. The child safety seat 10 can include a holder 512 for each of the at least one deformable body 510. Each holder 512 can be formed from a material, such as polypropylene, that is more rigid than the material of the at least one deformable body 510. Each holder 512 can define a cover configured to protect the respective deformable body 510 to prevent damage to the deformable body 510 due to an unintended impact. Each holder 512 can define a recess 512a therein configured to receive the respective deformable body 510 therein. Each recess 512 a can extend from an upper end 512 c of the holder 512 toward a lower end 512 d of the holder 512 .

[0068] Each holder 512 can be movably coupled to the first reclining foot 502. For example, each holder 512 can be configured to move relative to the first reclining foot 502 along an upward direction such that the respective deformable body 510 deforms between the holder 512 and the respective rigid portion 502d, such as the lower end 512d of the holder 512. The recess 512a of each holder 512 can be configured to receive the respective rigid portion 502d therein as the holder 512 moves upward relative to the rigid portion 502d (i.e., as energy is absorbed by the deformable body 510).

[0069] The child safety seat 10 may include, for each holder 512, at least one coupler 512b configured to movably couple the holder 512 to a respective rigid portion 502d. Each coupler 512b may be any suitable coupler. In one example, each coupler 512b may be a first protrusion or opening, and each rigid portion 502d may have a coupler 502h defining a second protrusion or opening configured to engage with the first protrusion or opening. The opening may be an elongated slot along the second direction D2, and the protrusion may be configured to translate within the slot along the second direction D2 to allow the holder 512 to translate upward relative to the first reclining foot 502.

[0070] Referring to FIG. 22 , in another example, at least one deformable body 510′ can be integral and monolithic with the corresponding rigid portion 502d′ of the first reclining foot 502′. In some such examples, the deformable body 510′ can define a plurality of deformable walls or ribs, as shown, or another suitable deformable structure. The deformable structure can have deformable walls, such as a honeycomb structure (not shown). The deformable structure can be integral and monolithic with the at least one rigid portion 502d′. The deformable structure can be configured to deform at a lower force than the remainder of the at least one rigid portion 502d′.

[0071] Also disclosed herein is a method for attaching a booster seat to a child safety seat body. The method can include positioning the booster seat relative to the body such that first and second arms of the booster seat engage sidewalls of the body. This engagement interface can position the booster seat relative to the body and ensure a secure and reliable connection between the body and the booster seat in the event of a collision or accident. The engagement between the arms of the booster seat and the sidewalls of the body can be provided in various configurations, as described herein. The method can further include selectively releasing the booster seat from the body, such as via a release latch and actuation. The actuator can be formed on a portion of the booster seat that is accessible when the booster seat is fully attached to the body.

[0072] The method can further include adjusting the body and / or booster seat, such as via a reclining base or assembly. The method can include adjusting a relative position of at least one reclining foot, which can be configured to selectively engage a vehicle support surface at various angles and positions. At least a portion of the reclining base can include a deformable body configured to absorb energy to protect an occupant of the child safety seat during an accident or collision.
