[0121] A detailed description of one or more embodiments of the disclosed apparatus and method are presented herein by way of exemplification and not limitation with reference to the Figures.

[0122] With reference to FIGS. 1 A-1D, an example of a child seat assembly 20 is illustrated. In the illustrated, non-limiting embodiment, the child seat assembly 20 can be detachably fixed to a vehicle seat (see FIG. 1C), such as via a latch or anchor mechanism 68a, 68b. This latch or anchor system often used is sometimes referred to as a “lower anchor and tether for children” e.g., LATCH system. Alternatively, or in addition, the child seat assembly 20 may be detachably fixed to a vehicle seat 10 via a vehicle belt associated with the vehicle seat 10. The child seat assembly 20 as illustrated and described herein is positionable in direct contact with a surface of the vehicle seat, such as in contact with a horizontal seat surface 11 for example. However, it should be understood that embodiments where the child seat assembly 20 is connectable to a support base (not shown) and the child seat assembly 20 is mountable to the vehicle seat 10 via the support base are also within the scope of the disclosure.

[0123] The child seat assembly 20 includes a seat shell 22 having a seat back 24 and a seat bottom 26. In an embodiment the seat bottom 26 is configured as a backless booster seat. Accordingly, the seat bottom 26 may also be referred to herein as a booster seat. The seat back 24 extends at an angle relative to the seat bottom 26. In the illustrated, non-limiting embodiments, the seat back 24 includes an upright support surface 30 generally facing forward and that extends from a first end or top 32 of the seat back 24 to a second, opposite end or bottom 34 of the seat back 24. A first upright side member 36 may be arranged at a first side 38 of the upright support surface 30 and a second upright side member 40 may be arranged at a second, opposite side 42 of the upright support surface 30. The first and second upright side members 36, 40 therefore form the left side and the right side of the seat back 24, respectively. As shown, the first and second upright side members 36, 40 extend forward from the upright support surface 30. The first and second upright side members 36, 40 may extend generally orthogonally to the upright support surface 30 or alternatively, may extendtherefrom at another angle, such as an angle greater than 90° for example. Accordingly, the upright support surface 30 and the first and second upright side members 36, 40 define a backrest region or upright support cavity within which an upper body of a child is receivable.

[0124] The upright side members 36, 40 may facilitate the correct positioning of a vehicle belt during one or more modes of operation when the child seat assembly 20 is installed within a vehicle. In some embodiments, each upright side member 36, 40 has an opening formed 44a, 44b therein. The openings 44a, 44b may be configured to receive a vehicle belt (not shown) to secure the child seat assembly 20 to a vehicle seat 10 in a forward-facing configuration or to secure an upper body of a child located within the cavity.

[0125] In the illustrated, non-limiting embodiments, the seat back 24 of the child seat assembly 20 includes a headrest 46. The headrest 46 may be attached to or integral with the seat back 24 or may be removably coupled thereto. The headrest 46 may be stationary, or in some embodiments, may be configured to move relative to the upright support surface 30. For example, the headrest 46 may be configured to translate relative to the upright support surface 30 between a lowered position and a raised position, allowing for adjustment based on the size of the child positioned within the child seat assembly 20. However, it should be appreciated that embodiments where the seat back 24 does not include a headrest 46 are also contemplated herein.

[0126] The seat bottom 26 of the child seat assembly 20 may include a seat support surface 50 facing generally upwardly and that extends from a first end or front 52 to a second end or back 54 of the seat bottom 26. When the child seat assembly 20 is in use, a child is supported on top of the seat support surface 50. A first seat side member 56 may be arranged at a first side 58 of the seat support surface 50 and a second seat side member 60 may be arranged at a second, opposite side 62 of the seat support surface 50. The first seat side member 56 and the second seat side member 60 extend upwardly and from the left side and the right side of the seat bottom 26. The seat support surface 50 and the first and second seat side members 56, 60 in combination define a region within which at least part of a lower body of a child may be received. The backrest region formed between the upright side members 36, 40 and the upright support surface 30 and the region formed between the seat side member 56, 60 and the seat support surface 50, in combination, define a child receiving area of the child seat assembly 20.

[0127] As shown, the seat side members 56, 60 extend at an angle from the seat support surface 50. The angle of the first seat side member 56 relative to the seat support surface 50 may but need not be the same as the angle of the first upright side member 36relative to the upright support surface 30. Similarly, the angle of the second seat side member 60 relative to the seat support surface 50 may but need not be the same as the angle of the second upright side member 40 relative to the upright support surface 30.

[0128] In the illustrated, non-limiting embodiment, each seat side member 56, 60 has a respective slot 66a, 66b formed therein configured to function as a belt guide for the lap portion of a vehicle belt and in some embodiments the shoulder portion of a vehicle belt, during at least one mode of use of the child seat assembly 20. In some modes of operation of the child seat assembly 20, the slots 66a, 66b may be configured to receive and position a lap belt portion of a vehicle restraint or a separate restraint belt to secure a child within the child seat assembly 20. It should be appreciated that the child seat assembly 20 illustrated in FIGS. 1 A-1C is represented by the seat shell 22 and soft goods (not shown) are positionable in overlapping arrangement with one or more portions of the seat shell 22, such as the upright support surface 30, a portion of the first and second upright side members 36, 40, the seat support surface 50, and a portion of the first and second seat side members 56, 60.

[0129] With continued reference to FIGS. 1 A-1D and further reference to FIGS. 2 A and 2B, the seat back 24 of the child seat assembly 20 may be separable from the seat bottom 26. In an embodiment, the child seat assembly 20 is a booster seat assembly. As shown, the seat back 24 of the child seat assembly 20 may be removably connectable to the seat bottom 26 to transform the child seat assembly 20 between a first booster configuration and a second booster configuration. In such embodiments, the seat bottom 26 may be considered a first booster portion and the seat back 24 may be considered a second booster portion. In the first booster configuration, the seat bottom 26 and the seat back 24 are connected to one another. The child seat assembly 20 in the first booster configuration may be a high back booster. In the second booster configuration, the seat back 24 may be separated from the seat bottom 26, and only the seat bottom 26 may be positioned on the seating surface 11 of the vehicle seat 10 for use. In this second booster configuration, the child seat assembly 20 may be a backless booster.

[0130] The seat back 24 of the child seat assembly 20 may include a back portion 70 and a seat portion 72. As shown, the back portion 70 may extend at a non-parallel angle relative to the seat portion 72 and the upright support surface 30 may be arranged at the back portion 70. In an embodiment, the back portion 70 is generally orthogonal to the seat portion 72 of the seat back 24, such as at an angle between 85 degrees and 110 degrees for example. In the illustrated, non-limiting embodiment the back portion 70 and the seat portion 72 of the seat back 24 are integrally formed such that the seat back 24 is a single, unitary body.However, embodiments where the back portion 70 and the seat portion 72 of the seat back 24 are formed separately and permanently or removably coupled to one another are also contemplated herein.

[0131] As shown, the seat back 24 may include a structural frame 74. In an embodiment, the structural frame 74 includes a first frame member 76a and a second frame member 76b laterally spaced from the first frame member 76a. The first frame member 76a may but need not be oriented generally parallel to the second frame member 76b. Although the first frame member 76a and the second frame member 76b are shown as two separate components, embodiments where the first frame member 76a and the second frame member 76b are integrally formed are also within the scope of the disclosure.

[0132] The first and second frame members 76a, 76b may be formed from a rigid material, such as from one or more pieces of metal tubing or channel. However, another material having any suitable configuration is contemplated herein. In the illustrated, nonlimiting embodiment, each of the first frame member 76a and the second frame member 76b has an L-shaped configuration that includes a respective first portion 78a, 78b (only a small portion thereof is shown in FIGS. 2A and 2B) and second portion 80a, 80b. The first portion 78a and second portion 80a of the first frame member 76a and the first portion 78b and second portion 80b of the second frame member 76b are arranged at an angle relative to one another. The first portion 78a, 78b and the second portions 80a, 80b of each frame member 76a, 76b may be formed by bending a single piece of tubing or alternatively, by permanently attaching, such as via welding for example, two separate pieces of tubing.

[0133] The first portion 78a of the first frame member 76a and the first portion 78b of the second frame member 76b are arranged at the back portion 70 of the seat back 24. In an embodiment, all or at least part of the first portion 78a of the first frame member 76a and the first portion 78b of the second frame member 76b are recessed or embedded within the seat shell 22 at the back portion 70. The first portion 78a of the first frame member 76a may be located near the first side 38 of the upright support surface 30 and the first portion 78b of the second frame member 76b may be located proximate the second side 42 of the upright support surface 30. A longitudinal axis of the first portion 78a of the first frame member 76a and a longitudinal axis of the first portion 78b of the second frame member 76b may both be parallel to a vertical axis.

[0134] The second portion 80a, 80b of each frame member 76a, 76b may be arranged at the seat portion 72 of the seat back 24. In an embodiment, the second portion 80a, 80b of both the first frame member 76a and the second frame member 76b extends generallyperpendicularly from the first portion 78a, 78b of a respective frame member 76a, 76b and from the upright support surface 30, such as at an angle between 85 degrees and 110 degrees for example. The angle between the first portion 78a, 78b and the second portion 80a, 80b of each frame member 76a, 76b may be substantially identical to the angle between the back portion 70 and the seat portion 72 of the seat back 24.

[0135] The second portion 80a, 80b of each frame member 76a, 76b may define a lateral side of the seat portion 72 of the seat back 24. In an embodiment, the seat portion 72 of the seat back 24 includes a body 82, such as positioned between the second portion 80a of the first frame member 76a and the second portion 80b of the second frame member 76b for example. As shown, the body 82 may extend beyond an end 84a, 84b of the second portion 80a, 80b of each of the first and second frame members 76a, 76b to form a distal end of the seat portion 72 of the seat back 24.

[0136] The seat portion 72 of the seat back 24 may be connectable to the seat bottom 26 of the child seat assembly 20 to affix the seat back 24 to the seat bottom 26. In an embodiment, the seat portion 72 of the seat back 24 is engageable with the seat bottom 26. As shown in FIG. 2B, a hollow cavity 86 may be formed within an interior of the seat bottom 26. The cavity 86 may be vertically offset from a bottom surface 51 of the seat bottom 26 positionable in contact with the seating surface 11 of the vehicle seat 10. The cavity 86 may have a size and shape generally complementary to the size and shape of the seat portion 72 of the seat back 24. Accordingly, in an embodiment, a substantial entirety of the seat portion 72 of the seat back 24 is receivable within the cavity 86 of the seat bottom 26.

[0137] With reference to FIGS. 1C and ID, when the seat back 24 is installed relative to the seat bottom 26 positioned on a seating surface 11 of a vehicle seat 10, the seat back 24 is supported by the seat bottom 26. A position of the seat back 24 relative to the seat bottom 26 may be defined by one or more of a position of the cavity 86 relative to the seat bottom 26, an angle between the seat portion 72 and the back portion 70 of the seat back 24, and a configuration of the back portion 70. As shown, the bottom end 34 of the seat back 24 may be vertically offset from the bottom surface 51 of the seat bottom 26. Accordingly, the seat back 24 is supported by the seat bottom 26 at a position offset from the seating surface 11. In such embodiments, the bottom end 34 of the seat back 24 does not directly contact the seating surface 11 of the vehicle seat 10. Rather, the seat back 24 is supported solely by the seat bottom 26 at a position above the seating surface 11.

[0138] In an embodiment, the seat back 24 is lockable in position relative to the seat bottom 26 via a locking mechanism 87 to prevent unintended separation of the seat back 24from the seat bottom 26. With reference to FIGS. ID, 2A, and 2B, the locking mechanism 87 for locking the seat back 24 to the seat bottom 26 includes a lock block 88, such as mounted at a front side of the seat shell 22 proximate the bottom end 34 of the back portion 70. The bottom end 34 of the back portion 70 may be a surface of the lock block 88. When the seat back 24 is coupled to the seat bottom 26, the lock block 88 may be aligned with or coplanar with a portion of the seat bottom 26. The locking mechanism additionally includes at least one locking pin 90a, 90b movably mounted to the lock block 88 and selectively engageable with the seat bottom 26. In the illustrated, non-limiting embodiment, a first locking pin 90a is movably mounted at a first lateral side of the lock block 88 and a second locking pin 90b is movably mounted at an opposite, second lateral side of the lock block 88. The first and second locking pins 90a, 90b may be coaxial, and in some embodiments, are movable along a horizontally oriented axis.

[0139] Each of the first locking pin 90a and the second locking pin 90b may be movable relative to the seat back 24 between an extended position and a retracted position (not shown in this embodiment). A first biasing member 92a may be operably coupled to the first locking pin 90a and is operable to bias the first locking pin 90a outwardly, away from the lock block 88 and toward the extended position. Similarly, a second biasing member 92b may be operably coupled to the second locking pin 90b and is operable to bias the second locking pin 90b outwardly, away from the lock block 88 and toward the extended position. Although a separate biasing mechanism is described herein with respect to each locking pin 90a, 90b, it should be appreciated that embodiments where a single biasing mechanism is operably coupled to both locking pins 90a, 90b are also contemplated herein.

[0140] In the extended position, the first locking pin 90a and the second locking pin 90b protrude beyond the respective lateral sides of the seat portion 72 of the seat back 24. As shown in FIG. 2A, in the extended position, the first locking pin 90a may extend beyond the first frame member 76a and the second locking pin 90b may extend beyond the second frame member 76b, respectively. In their respective retracted positions, the first locking pin 90a may not extend beyond the first frame member 76a and the second locking pin 90b may not extend beyond the second frame member 76b.

[0141] With reference to FIGS. 2B and 2C, a first opening 94a may be arranged at a first surface 95 of the seat bottom 26 within or proximate the cavity 86, and a second opening 94b may be arranged at a second surface 97 of the seat bottom 26 within or proximate the cavity 86. When the seat portion 72 of the seat back 24 is fully inserted into the cavity 86, the first locking pin 90a is aligned with and is positionable within the first opening (not shown)and the second locking pin 90b is aligned with and is positionable within the second opening 94b. To lock the seat back 24 to the seat bottom 26 such that the seat back 24 is not separable therefrom, the locking pins 90a, 90b are transformed to their extended positions and received within the respective openings 94 of the seat bottom 26.

[0142] At least one actuator, such as a lock pin actuator 96 for example, may be operably coupled to the first locking pin 90a and the second locking pin 90b. The lock pin actuator 96 may be operable to transform the locking pins 90a, 90b to the retracted position to decouple the locking pins 90a, 90b from the first opening 94a and the second opening 94b, respectively, and therefore unlock the seat back 24 from the seat bottom 26. The lock pin actuator 96 includes one or more handles exposed at an exterior of the child seat assembly 20 and engageable by a caregiver. In an embodiment, the one or more handles 98a, 98b are arranged at the seat back 24, such as at a back side 91 of the back portion 70. As shown, the handles 98a, 98b may be arranged at the lock block 88 or, alternatively or additionally, may be accessible via the lock block 88. However, embodiments where a handle 98a, 98b of a lock pin actuator 96 is arranged at another location about the seat back 24 or about the child seat assembly 20 are also contemplated herein.

[0143] In the illustrated, non-limiting embodiment, the one or more handles includes a first handle 98a operably coupled to the first locking pin 90a and a second handle 98b operably coupled to the second locking pin 90b. Application of a force to the first handle 98a, such as toward a center of the seat back 24 for example, moves the first locking pin 90a against the bias of the first biasing member (not shown). With the force applied to the first handle 98a, the first locking pin 90a is retracted toward the seat portion 72, to a position where the first locking pin 90a does not protrude beyond the lateral side of the seat portion 72 as defined by the first frame member 76a. Similarly, operation of the second handle 98b via application of a force thereto, such as toward a center of the seat back 24 for example, moves the second locking pin 90b against the bias of the second biasing member (not shown), causing the second locking pin 90b to retract into the seat portion 72. In this retracted position, the second locking pin 90a may not protrude beyond the lateral side of the seat portion 72 as formed by the second frame member 76b.

[0144] With the locking pins 90a, 90b in the retracted position, the seat portion 72 of the seat back 24 can be slidably inserted into or removed from the cavity 86 of the seat bottom 26. Upon release of the handles 98a, 98b, the biasing force of each biasing members 92a, 92b will bias a respective locking pin 90a, 90b outwardly. If the seat portion 72 is properly positioned within the cavity 86 at the time that the handles 98a, 98b are released, thelocking pins 90a, 90b are biased into engagement with the adjacent openings 94 formed in the seat bottom 26 to lock the seat back 24 to the seat bottom 26.

[0145] It should be appreciated that although the lock pin actuator 96 is illustrated and described herein as having a plurality of handles 98a, 98b, embodiments including a single handle operably coupled to each of the first locking pin 90a and the second locking pin 90b are also within the scope of the disclosure. Further, although the handles 98a, 98b are illustrated as being translatable along a generally horizontal axis, such as toward one another for example, to retract the locking pins 90a, 90b, it should be appreciated that the handles 98a, 98b may move in any suitable manner, such as via translation along an axis parallel to the seat portion 72 or via rotation about any suitable axis for example.

[0146] With reference now to FIGS. 3A-3F, a child seat assembly 120 according to another embodiment is illustrated. The child seat assembly 120 of FIGS. 3A-3F may be similar to that of FIGS. 1 A-1D. The child seat assembly 120 may include a seat shell 122 having a seat back 124 and a seat bottom 126. As in the previous embodiment, the seat back 124 may extend at an angle relative to the seat bottom 126. In the illustrated, non-limiting embodiments, the seat back 124 includes an upright support surface 130 generally facing forward and that extends generally between a first end or top 132 of the seat back 124 to a second, opposite end or bottom 134 of the seat back 124. A first upright side member 136 may be arranged at a first side 138 of the upright support surface 130 and a second upright side member 140 may be arranged at a second, opposite side 142 of the upright support surface 130. The first and second upright side members 136, 140 therefore form the left side and the right side of the seat back 124, respectively. As shown, the first and second upright side members 136, 140 extend forward from the upright support surface 130. The first and second upright side members 136, 140 may extend generally orthogonally to the upright support surface 130 or alternatively, may extend therefrom at another angle, such as an angle greater than 90° for example. Accordingly, the upright support surface 130 and the first and second upright side members 136, 140 define a backrest region or upright support cavity within which an upper body of a child is receivable. In some embodiments, each upright side member 136, 140 has a respective opening formed 144a, 144b therein. The openings 144a, 144b may be configured to receive a vehicle belt (not shown) to secure the child seat assembly 120 to a vehicle seat 110 in a forward-facing configuration or to secure an upper body of a child located within the cavity.

[0147] In the illustrated, non-limiting embodiments, the seat back 124 of the child seat assembly 120 includes a headrest 146. The headrest 146 may be attached to or integralwith the seat back 124 or may be removably coupled thereto. The headrest 146 may be stationary, or in some embodiments, may be configured to move relative to the upright support surface 130. For example, the headrest 146 may be configured to translate relative to the upright support surface 130 between a lowered position and a raised position, allowing for adjustment based on the size of the child positioned within the child seat assembly 120. However, it should be appreciated that embodiments where the seat back 124 does not include a headrest 146 are also contemplated herein.

[0148] The seat bottom 126 may include a seat support surface 150 facing generally upwardly and that extends from a first end or front 152 to a second end or back 154 of the seat bottom 126. A first seat side member 156 may be arranged at a first side 158 of the seat support surface 150 and a second seat side member 160 may be arranged at a second, opposite side 162 of the seat support surface 150. The first seat side member 156 and the second seat side member 160 extend upwardly and from the left side and the right side of the seat bottom 126. The seat support surface 150 and the first and second seat side members 156, 160 in combination define a region within which at least part of a lower body of a child may be received. The backrest region formed between the upright side members 136, 140 and the upright support surface 130 and the region formed between the seat side member 156, 160 and the seat support surface 150, in combination, define a child receiving area of the child seat assembly 120.

[0149] As shown, the seat side members 156, 160 extend at an angle from the seat support surface 150. The angle of the first seat side member 156 relative to the seat support surface 150 may but need not be the same as the angle of the first upright side member 136 relative to the upright support surface 130. Similarly, the angle of the second seat side member 160 relative to the seat support surface 150 may but need not be the same as the angle of the second upright side member 140 relative to the upright support surface 130.

[0150] Each seat side member 156, 160 has a respective slot 166a, 166b formed therein configured to function as a belt guide for the lap portion of a vehicle belt and in some embodiments the shoulder portion of a vehicle belt, during at least one mode of use of the child seat assembly 120. In some modes of operation of the child seat assembly 120, the slots 166a, 166b may be configured to receive and position a lap belt portion of a vehicle restraint or a separate restraint belt to secure a child within the child seat assembly 120. Although not shown, soft goods are positionable in overlapping arrangement with one or more portions of the seat shell 122, such as the upright support surface 130, a portion of the first and secondupright side members 136, 140, the seat support surface 150, and a portion of the first and second seat side members 156, 160.

[0151] With continued reference to FISG. 3A-3F and further reference to FIGS. 4A- 10, the child seat assembly 120 may be a booster seat assembly and the seat bottom 126 may be configured as a backless booster seat. In an embodiment, the seat back 124 is removably connectable to the seat bottom 126 to transform the child seat assembly 120 between a first booster seat configuration and a second booster seat configuration.

The first and second locking pins 190a, 190b may be movable between an extended position (FIGS. 4A-5A and 7A) and a retracted position (FIG. 7B). In the extended position, the first locking pin 190a and the second locking pin 190b protrude beyond the lateral sides of the seat portion 172 of the seat back 124 and are configured to engage a respective portion of the seat bottom 126. As shown, in an embodiment, in the extended position the first locking pin 190a extends beyond the first frame member 176a and the second locking pin 190b extends beyond the second frame member 176b, respectively.

[0161] In the retracted position, the locking pins 190a, 190b are drawn towards an interior center of the lock block 188. In an embodiment, the first and second locking pins 190a, 190b do not extend beyond the respective first and second frame members 176a, 176b when in the retracted position. Accordingly, a greater portion of the locking pins 190a, 190b protrudes from the lock block 188 when the locking pins 190a, 190b are in the extended position than in the retracted position. With reference to FIG. 10, a first biasing member 192a may be operably coupled to the first locking pin 190a and is operable to bias the first locking pin 190a outwardly from the lock block 188 in a first direction. Similarly, a second biasingmember 192b may be operably coupled to the second locking pin 190b and is operable to bias the second locking pin 190b outwardly from the lock block 188 in a second opposite direction.

[0162] As shown in FIGS. 8A, 8B, and 10, a first opening 194a may be arranged at a first surface 195a of the seat bottom 126 within or proximate the cavity 186 and a second opening 194b may be arranged at a second surface 195b of the seat bottom 126 within or proximate the cavity 186. With the seat portion 172 inserted into the cavity 186, the first locking pin 190a is aligned with and is positionable within the first opening 194a and the second locking pin 190b is aligned with and is positionable within the second opening 194b. With the locking pins 190a, 190b engaged with the respective openings 194a, 194b, the seat back 124 is locked in position relative to the seat bottom 126.

[0163] A lock pin actuator 196 is operably coupled to the first locking pin 190a and the second locking pin 190b, and is operable to transform the locking pins 190a, 190b from the extended position to the retracted position. In the illustrated, non-limiting embodiment, the lock pin actuator 196 includes a first handle 198a operably coupled to the first locking pin 190a and a second handle 198b operably coupled to the second locking pin 190b. As shown, the first handle 198a and second handle 198b may be arranged at a backside 191 of the back portion 170 of the seat back 124, such as proximate the lock block 188 for example. As shown, the handles 198a, 198b may be arranged at the lock block 88 or, alternatively or additionally, may be accessible via the lock block 188. However, embodiments where a handle 198a, 198b of a lock pin actuator 196 is arranged at another location about the seat back 124 or about the child seat assembly 120 are also contemplated herein.

[0164] In the illustrated, non-limiting embodiment, the first handle 198a includes a first handle protrusion 200a and the second handle 198b includes a second handle protrusion 200b (see FIGS. 5 A, 7 A and 10). The first and second handle protrusions 200a, 200b are movable, for example via the first handle 198a and the second handle 198b, respectively, between an extended position (FIGS. 7A and 10) and a retracted position (FIG. 7B). When the first handle 198a and the second handle 198b are unactuated, the first handle protrusion 200a may extend beyond the lock block 188 in the first direction and the second handle protrusion 200b may extend beyond the lock block 188 in the second direction. In the extended position, the first handle protrusion 200a and the second handle protrusion 200b protrude beyond the lateral sides of the seat portion 172 of the seat back 124, such as beyond the first frame member 176a and the second frame member 176b, respectively. In the retracted position, as shown in FIG. 7B, the handle protrusions 200a, 200b are translatedinwardly into the lock block 188. In the retracted position, the first handle protrusion 200a may not extend beyond the first frame member 176a and second handle protrusion 200b may not extend beyond the second frame member 176b.

[0165] As shown, the locking pins 190a, 190b and the handle protrusions 200a, 200b may be offset from one another along an axis X (see FIG. 5B) extending parallel to the seat portion 172 of the seat back 124. For example, the locking pins 190a, 190b may be located closer to the upright support surface 130 of the back portion 170 and the handle protrusions 200a, 200b may be located closer to the rear of the back portion 170. As shown in FIGS. 8A and 10, the seat bottom 126 may include a first slot 202a at or proximate the cavity 186 for receiving the first handle protrusion 200a and a second slot 202b at or proximate the cavity 186 for receiving the second handle protrusion 200b. When the seat portion 172 is fully inserted into the cavity 186, the first handle protrusion 200a is aligned with and is receivable within the first slot 202a and the second handle protrusion 200b is aligned with and is receivable within the second slot 202b. With the handle protrusions 200a, 200b engaged with the respective slots 202a, 202b, the seat back 124 is locked in position relative to the seat bottom 126.

[0166] Application of a force to the first handle 198a, such as toward a center of the seat back 124 for example, moves the first locking pin 190a against the bias of the first biasing member 192a toward the retracted position. Application of the force to the first handle 198a similarly moves the first handle protrusion 200a toward the retracted position. Application of a force to the second handle 198b toward a center of the seat back 124 moves the second locking pin 190b against the bias of the second biasing member 192b toward the retracted position and moves the second handle protrusion 200b toward the retracted position.

[0167] With the locking pins 190a, 190b and the handle protrusions 200a, 200b retracted, the seat portion 172 of the seat back 124 can be slidably inserted into or separated from the cavity 186 of the seat bottom 126. Upon release of the first handle 198a and the second handle 198b, the biasing force of each biasing member 192a, 192b will bias a respective locking pin 190a, 190b outwardly. Due to the interconnection between the handles 198a, 198b and the locking pins 190a, 190b, this biasing force may similarly bias the handles 198a, 198b to an unactuated position, and therefore in some embodiments, may bias the handle protrusions 200a, 200b to the extended position. If the seat portion 172 is positioned within the cavity 186 at the time that the force is removed from the handles 198a, 198b, the locking pins 190a, 190b are biased into engagement with the adjacent openings 194a, 194b formed in the seat bottom 26 and the handle protrusions 200a, 200b are biased intoengagement with the adjacent slots 202a, 202b to lock the seat back 124 to the seat bottom 126.

[0168] In an embodiment, the seat back 124 includes a biasing mechanism having a biasing force operable to bias the seat back 124 out of engagement with the seat bottom 126 when the seat back 124 is not locked in position relative to the seat bottom 126. As shown in FIGS. 4A-12B, the biasing mechanism includes at least one ejection post 210a, 210b, such as a first ejection post 210a movably mounted within the second portion 180a of the first frame member 176a and a second ejection post 210b movably mounted within the second portion 180b of the second frame member 176b.

[0169] The second ejection post 210b according to an embodiment is illustrated in more detail in FIGS. 11 A-12B. Although the first ejection post 210a is not shown in detail, it should be appreciated that a configuration of the first ejection post 210a may be substantially identical to the configuration of the second ejection post 210b as described herein. As shown, the second ejection post 210b may have a slot 212 formed therein, and a pin or shaft 214 extending from an interior of the second frame member 176b may be disposed within the slot 212. In such embodiments, the pin 214 and slot 212 define a path of translation of the second ejection post 210b relative to the second frame member 176b. A biasing member 216, such as a coil spring for example, may be fixed to a surface of the second frame member 176b and to a surface of the second ejection post 210b.

[0170] The second ejection post 210b is movable relative to the second frame member 176b between a first, extended position and a second, retracted position. In the first, extended position, as shown in FIGS. 11 A-l IB, an end 218 of the second ejection post 210b may protrude beyond the end 184b of the second frame member 176b. In the first, extended position, the pin 214 may be arranged at a first end 220 of the slot 212. The biasing member 216 may be operable to bias the second ejection post 210b toward the first, extended position. In the second, retracted position, the second ejection post 210b is translated into the interior of the second frame member 176b such that the end 220 of the second ejection post 210b is proximate, and in some embodiments is substantially aligned with, the end 184b of the second portion 180b of the second frame member 176b. Further, the pin 214 may be engaged with the second, opposite end 222 of the slot 212 in the retracted position. As the second ejection post 210b translates toward the second, retracted position, the second ejection post 210b applies a force to the biasing member 216 in a direction opposite its bias.

[0171] During connection of the seat back 124 to the seat bottom 126, the second ejection post 210a, 210b is biased by the biasing member 216 to the first, extended position.As the seat portion 172 of the seat back 224 is slidably received within the cavity 186 of the seat bottom 126, the end 218 of the second ejection post 210b contacts a corresponding surface of the cavity 186. This engagement applies a force to the second ejection post 210b in a direction opposing the bias of the biasing member 216. Accordingly, the second ejection post 210b translates relative to the second frame member 176b toward the second, retracted position as the seat portion 172 is installed within the cavity 186. It should be appreciated that the first ejection post 210a may be similarly retracted against its bias in response to installing the seat portion 172 of the seat back 124 into the cavity 186. The engagement of the locking pins 190a, 190b, and in some embodiments the handle protrusions 200a, 200b, with the seat bottom 126 restricts movement of the seat back 124 away from the seat bottom 126. As a result, this engagement maintains the ejection posts 210a, 210b in the retracted position.

[0172] Upon operation of the lock pin actuator 196, the locking pins 190a, 190b and / or handle protrusions 200a, 200b are retracted into the seat back 124 and disengage from the seat bottom 126. Without this engagement to oppose movement of the seat back 124 and / or the ejection posts 210a, 210b, the biasing force of the biasing member (not shown) of the first ejection post 210a and the biasing force of the biasing member 216 of the second ejection post 210b will bias the ejections posts 210a, 210b toward the extended position. Because the ejection posts 210a, 210b, themselves, are blocked from moving forward by an adjacent wall of the cavity 186, the frame members 176a, 176b are instead configured to translate relative to the ejection posts 210a, 210b. Accordingly, the biasing force of the biasing member 216 of each ejection post 210a, 210b causes the seat portion 172 of the seat back 124 to translate toward the open end of the cavity 186, away from the seat bottom 126.

[0173] With reference now to FIGS. 13A-14B, in the illustrated, non-limiting embodiment, a support member 230 is movably mounted in overlapping arrangement with the upright support surface 150 of the seat shell 122 at the seat bottom 126. The support member 230 may have an upper support surface 232 oriented generally parallel to the seat support surface 150 of the seat shell 122. The support member 230 may be formed separately from the seat shell 122 and may be movably coupled thereto. It may be desirable to adjust a position of the support member 230, and therefore the upper support surface 232, relative to the seat shell 122 of the seat bottom 126 based on the size of the child positioned therein, such as to provide additional support to the legs of the child for example.

[0174] As shown in FIGS. 14A and 14B, in an embodiment, the seat support surface 150 may have one or more slots or tracks 250a, 250b formed therein and one or more engagement members 252a, 252b extending from the support member 230, may be slidablyarranged within each slot or track. In the illustrated, non-limiting embodiment, the seat support surface 150 has a first slot 250a and a second substantially identical slot 205b formed therein and oriented parallel to one another. The support member 230 similarly has a first engagement member 252a and a second engagement member 252b protruding downwardly from a bottom surface 238 of the support member 230 and oriented parallel to one another. A distance between the first slot 250a and the second slot 250b may be substantially identical to the distance between the first engagement member 252a and the second engagement member 252b such that the first engagement member 252a is receivable within the first slot 250a and the second engagement member 252b is receivable within the second slot 250b. The translational movement of the engagement members 252a, 252b within the slots 250a, 250b defines the path of movement of the support member 230 relative to the seat bottom 126. In the illustrated, non-limiting embodiment, the support member 230 is movable along a path extending parallel to axis X of the seat bottom 126.

[0175] In an embodiment, at least one seat lock is disposed at a lateral side of the support member 230. In the illustrated, non-limiting embodiment, a first seat lock 254a is disposed at a first lateral side 255 and a second seat lock 254b is disposed at a second, opposite lateral side 258 of the support member 230. The first seat lock 254a is slidably arranged within a first locking slot 256a formed in the seat support surface 150 and the second seat lock 254b is slidably arranged within a second locking slot (not shown) formed in the sea support surface 150. As shown, the second seat lock 254b has a hole 262 formed therein. It should be appreciated that the first seat lock 254a similarly has a hole (not shown) formed therein.

[0176] With reference the first locking slot 256a, one or more engagement features 264 may protrude from a surface of the locking slot 256a, such as toward the seat lock for example. Each of the engagement features 264 is receivable within the hole (not shown) of the first seat lock 254a. Although not shown, the second locking slot may similarly include one or more engagement features 264 engageable with the hole 262 formed in the second seat lock 254b. The support member 230 is locked against movement relative to the seat support surface 150 when each seat lock 254a, 254b is engaged with an engagement member of the corresponding locking slot 256a. Although not shown, a respective biasing member may be operably coupled to each seat lock 254a, 254b to bias each seat lock 254a, 254b into engagement with the engagement features 264.

[0177] An actuator 266 may be operably coupled to the first and second seat locks 254a, 254b, and is operable to selectively disengage the seat locks 254a, 254b from theengagement members 264, thereby allowing the seat support member 230 to slide relative to the seat support surface 150. When the actuator 266 is operated, such as via application of a force to a handle 268 of the actuator 266 for example, a connection (not shown) extending between the actuator handle 268 and the seat locks 254a, 254b transmits the force to the seat locks 254a, 254b. The force is in a direction opposing the biasing forces, causing the seat locks 254a, 254b to disengage from an adjacent engagement member 264. While disengaged, the support member 230 is translatable to a desired position. Upon removal of the force from the handle 268, the biasing forces of the biasing members will bias each seat locks 254a, 254b into engagement with an adjacent engagement member 264, thereby locking the support member 230 in position.

[0178] As shown, the support member 230 may be movable from a first, rearmost position (FIG. 13 A) in which the front 240 of the upper support surface 232 is aligned with or located directly adjacent to the front 152 of the seat support surface 150 to a second, foremost position in which front 240 of the upper support surface 232 is spaced forward from the front 152 of the upright support surface 150. It should be appreciated that the support member 230 may be positionable at one or more intermediate positions along the path of movement, as shown in FIGS. 13B and 13C, between the first position (FIG. 13A) and the second position (FIG. 13B). The support member 230 may be lockable at a plurality of distinct positions relative to the seat bottom 126. It should be appreciated that any suitable mechanism, such as spring biased pins for example, may be used to lock the support member 230 at any or all of the plurality of positions.

[0179] With reference now to FIGS. 15A-23B, yet another embodiment of a child seat assembly 320 is illustrated according to an embodiment. As in the previous embodiments, the child seat assembly 320 may include a seat shell 322 having a seat back 324 and a seat bottom 326. The seat back 324 may extend at an angle relative to the seat bottom 326. In the illustrated, non-limiting embodiments, the seat back 324 includes an upright support surface 330 generally facing forward and that extends from a first end or top 332 of the seat back 324 to a second, opposite end or bottom 334 of the seat back 324. A first upright side member 336 may be arranged at a first side 338 of the upright support surface 330 and a second upright side member 340 may be arranged at a second, opposite side 342 of the upright support surface 330. The first and second upright side members 336, 340 therefore form the left side and the right side of the seat back 324, respectively.

[0180] As shown, the first and second upright side members 336, 340 extend forward from the upright support surface 330. The first and second upright side members 336, 340may extend generally orthogonally to the upright support surface 330 or alternatively, may extend therefrom at another angle, such as an angle greater than 90° for example. Accordingly, the upright support surface 330 and the first and second upright side members 336, 340 define a backrest region or upright support cavity within which an upper body of a child is receivable. In some embodiments, each upright side member 336, 340 has a respective opening formed 344a, 344b therein configured to receive a vehicle belt (not shown) to secure the child seat assembly 320 to a vehicle seat 310 in a forward-facing configuration or to secure an upper body of a child located within the cavity.

[0181] In the illustrated, non-limiting embodiments, the seat back 324 of the child seat assembly 320 includes a headrest 346. The headrest 346 may be attached to or integral with the seat back 324 or may be removably coupled thereto. The headrest 346 may be stationary, or in some embodiments, may be configured to move relative to the upright support surface 330. For example, the headrest 346 may be configured to translate relative to the upright support surface 330 between a lowered position and a raised position, allowing for adjustment based on the size of the child positioned within the child seat assembly 320. However, it should be appreciated that embodiments where the seat back 324 does not include a headrest 346 are also contemplated herein.

[0182] The seat bottom 326 may include a seat support surface 350 facing generally upwardly and that extends from a first end or front 352 to a second end or back 354 of the seat bottom 326. A first seat side member 356 may be arranged at a first side 358 of the seat support surface 350 and a second seat side member 360 may be arranged at a second, opposite side 362 of the seat support surface 350. The first seat side member 356 and the second seat side member 360 extend upwardly and from the left side and the right side of the seat bottom 326. The seat support surface 350 and the first and second seat side members 356, 360 in combination define a region within which at least part of a lower body of a child may be received. The backrest region formed between the upright side members 336, 340 and the upright support surface 330 and the region formed between the seat side 356, 360 and the seat support surface 350, in combination, define a child receiving area of the child seat assembly 320.

[0183] The seat side members 356, 360 extend at an angle from the seat support surface 350. The angle of the first seat side member 356 relative to the seat support surface 350 may but need not be the same as the angle of the first upright side member 336 relative to the upright support surface 330. Similarly, the angle of the second seat side member 360relative to the seat support surface 350 may but need not be the same as the angle of the second upright side member 340 relative to the upright support surface 330.

[0184] Each seat side member 356, 360 has a respective slot 366a, 366b formed therein configured to function as a belt guide for the lap portion of a vehicle belt and in some embodiments the shoulder portion of a vehicle belt, during at least one mode of use of the child seat assembly 320. In some modes of operation of the child seat assembly 320, the slots 366a, 366b may be configured to receive and position a lap belt portion of a vehicle restraint or a separate restraint belt to secure a child within the child seat assembly 320. Although not shown, soft goods are positionable in overlapping arrangement with one or more portions of the seat shell 322, such as the upright support surface 330, a portion of the first and second upright side members 336, 340, the seat support surface 150, and a portion of the first and second seat side members 356, 360.

[0185] As in the previous embodiment, the child seat assembly 320 may be a booster seat and the seat back 324 may be removably connectable to the seat bottom 326 to transform the child seat assembly 320 between a first booster seat configuration and a second booster seat configuration. The seat back 324 of the child seat assembly 320 may include a back portion 370 and a seat portion 372. As shown, the back portion 370 be arranged at an angle relative to the seat portion 372 and may include the upright support surface 330. In an embodiment, the back portion 370 is generally orthogonal to the seat portion 372 of the seat back 324. In the illustrated, non-limiting embodiment, the back portion 370 and the seat portion 372 are integrally formed with one another; however, embodiments where the back portion 370 and the seat portion 372 of the seat back 324 are formed separately and are permanently or removably connected are also contemplated herein.

[0186] The child seat assembly 320 may be a booster seat assembly and the seat bottom 326 may be configured as a backless booster seat. In an embodiment, the seat back 324 is removably connectable to the seat bottom 326 to transform the child seat assembly 320 between a first booster seat configuration and a second booster seat configuration. The seat back 324 of the child seat assembly 320 may include a back portion 370 and a seat portion 372. As shown, the back portion 370 be arranged at an angle relative to the seat portion 372. In an embodiment, the back portion 370 is generally orthogonal to the seat portion 372 of the seat back 324, such as at an angle between about 85 degrees and about 110 degrees for example. In the illustrated, non-limiting embodiment, the back portion 370 and the seat portion 372 are integrally formed with one another; however, embodiments where the backportion 370 and the seat portion 372 of the seat back 324 are formed separately and are permanently or removably connected are also contemplated herein.

[0187] The seat back 324 may include a rigid structural frame 374, for example including a first frame member 376a and second frame member 376b. The first frame member 376a may be oriented generally parallel to the second frame member 376b. The first frame member 376a and the second frame member 376b may be formed as separate components or may be integrally formed. In the illustrated, non-limiting embodiment, both the first frame member 376a and the second frame member 376b have an L-shaped configuration that includes a respective first portion 378a, 378b (see FIGS. 16B and 17B) and second portion 380a, 380b arranged at an angle relative to the first portion 378a, 378b. The first and second portions 378a, 378b, 380a, 380b of each frame member 376a, 376b may be formed by bending a single piece of tubing or alternatively, by permanently attaching, such as via welding for example, two separate pieces of tubing.

[0188] In an embodiment, both the first portion 378a of the first frame member 376a and the first portion 378b of the second frame member 376b are arranged at the back portion 370 of the seat back 324. Each first portion 378a, 378b may be embedded within or arranged within a respective recess formed in the seat shell 322 at the back portion 370 of the seat back 324. The first portion 378a of the first frame member 376a may be located near the first side 338 of the upright support surface 330 and the first portion 378b of the second frame member 376b may be located proximate the second side 342 of the upright support surface 330. In an embodiment, longitudinal axes L3a, L3b (FIG. 17B) of the first portion 378a of the first frame member 376a and the first portion 378b of the second frame member 376b, respectively, extend along a vertical axis.

[0189] In an embodiment, the second portions 380a, 380b of both the first frame member 376a and the second frame member 376bare arranged at the seat portion 372 of the seat back 324. The second portion 380a, 380b of each frame member 376a, 376b may be located near the bottom end 334 of the upright support surface 330. In an embodiment, the second portion 380a extends generally perpendicularly from the first portion 378a of the first frame member 376a and the second portion 380b extend generally perpendicularly from the first portion 378b of the second frame member 376b. The second portions 380a, 380b of both frame members 376a, 376b may extend generally perpendicularly from the upright support surface 330. The angle between the first portion 378a, 378b and the second portion 380a, 380b of each frame member 376a, 376b may be substantially identical to the angle between the back portion 370 and the seat portion 372 of the seat back 324.

[0190] The seat portion 372 of the seat back 324 may include a body 382, such as positioned between the second portion 380a of the first frame member 376a and the second portion 380b of the second frame member 376b for example. As shown, the body 382 may extend beyond the ends 384a, 384b of the second portions 380a, 380b of the frame members 376a, 376b to form a distal end of the seat portion 372 of the seat back 324. In an embodiment, the second portion 380a, 380b of each frame member 376a, 376b defines a lateral side of the seat portion 372 of the seat back 324.

[0191] The seat portion 372 of the seat back 324 may be positionable about the seat bottom 326 of the child seat assembly 320 to affix the seat back 324 to the seat bottom 326. In an embodiment, the seat portion 372 of the seat back 324 is engageable with the seat bottom 326. Although not shown, it should be appreciated that seat bottom 326 has an internal cavity formed therein, similar to cavities 86 and 186 previously described herein. The seat bottom 326 may further include one or more openings, similar to openings 94, 194a, 194b, as previously described herein.

[0192] The seat back 324 is lockable via a locking mechanism 387 in position relative to the seat bottom 326 for use of the child seat in the first booster configuration. With reference to FIGS. 16B and 17B, the locking mechanism 387 for locking the seat back 324 to the seat bottom 326 includes a lock block 388 may be mounted at a front side of the seat shell 322, such as proximate the bottom end 334 of the seat back 324. The locking mechanism additionally includes at least one locking pin 390a, 390b selectively engageable with the seat bottom 326. In the illustrated, non-limiting embodiment, a first locking pin 390a is movably mounted at a first lateral side of the lock block 388 and a second locking pin 390b is movably mounted at an opposite, second lateral side of the lock block 388. The first and second locking pins 390a, 390b may be coaxial, and in some embodiments, are positioned parallel to a horizontally oriented axis.

[0193] Each of the first locking pin 390a and the second locking pin 390b may be movable relative to the seat back 324 between an extended position (FIG. 16B) and a retracted position (FIG. 17B). In the extended position, the first locking pin 390a and the second locking pin 390b protrude beyond the respective lateral sides of the seat portion 372 formed by the first frame member 376a and the second frame member 376b, respectively. In their respective retracted positions, the first locking pin 390a may not extend beyond the first frame member 376a and the second locking pin 390b may not extend beyond the second frame member 376b. With the seat portion 372 of the seat back 324 fully inserted into the cavity (not shown) of the seat bottom 326, the first locking pin 390a is receivable within thefirst opening (not shown) and the second locking pin 390b is receivable within a second opening (not shown), thereby restricting separation of the seat back 324 from the seat bottom 326. Such a configuration is similar to that shown in FIG. 2C.

[0194] A lock pin actuator 396 is operably coupled to the first locking pin 390a and the second locking pin 390b and is operable to move the locking pins 390a, 390b out of engagement with the respective openings of the seat bottom 326. As shown, the lock pin actuator 396 includes a handle 398 exposed at an exterior of the child seat assembly 320 and engageable by a caregiver. In the illustrated, nondimiting embodiment, the lock pin actuator 396 includes a single handle 398 arranged at the bottom end 334 of the back portion 370, proximate a back side 391 thereof. However, embodiments including a handle 398 arranged at another location about the seat back 24 are also within the scope of the disclosure.

[0195] As shown, the handle 398 is translatable relative to the seat shell 322 along an axis oriented substantially parallel to the back portion 370 of the seat back 324 between an unoperated position and an operated position. In the unactuated or unoperated position, the handle 398 is retracted within the seat shell 322 such that a free end 399 of the handle 398 is substantially flush with the bottom end 334 of the seat shell 322. When the handle 398 is in the unactuated position, the locking pins 390a, 390b operably coupled thereto are in the extended position. Similarly, when the handle 398 is in the operated or actuated position, the locking pins 390a, 390b operably coupled thereto are in the retracted position. In an embodiment, the locking pins 390a, 390b are directly driven between the extended and retracted positions by the handle 398. For example, as shown in FIGS. 16B and 17B, the handle 398 may have a first angled slot and a second angled slot formed therein. The first locking pin 390a may be engaged with the first angled slot and the second locking pin 390b may be engaged with the second angled slot. The angle of the slots causes each respective locking pin 390a, 390b to translate laterally relative to the lock block 388 as the handle 398 moves vertically between the operated an unoperated positions.

[0196] To operate the lock pin actuator 396, a user applies a downward force to the handle 398, causing the handle 398 to translate outwardly, beyond the bottom end 334 of the seat back 324. In an embodiment, the handle 398 is configured to remain in this operated position until manually moved to the unoperated position by a user. Accordingly, the handle 398 may remain in this extended position as the seat portion 372 of the seat back 324 is installed about the seat bottom 326. Once properly positioned, a user applies a second, upward force to the handle 398, causing the handle to translate into the seat shell 322 of the seat back 324. As the handle 398 translates upwardly, the locking pins 390a, 390b areconfigured to move outwardly, and into corresponding openings (not shown) formed in the seat bottom 326. In an embodiment, as shown in FIG. 19B, a detent 400 is arranged at an upper end of the handle 398 and when seat back 324 with the handle 398 in the deployed or extended position is coupled to the seat bottom 326, the detent 400 is engaged with a corresponding surface of the seat bottom 326. The engagement between the detent 400 and the surface of the seat bottom 326 restricts the handle 398 from moving relative to the seat back 324 to the retracted position. As an upward force is applied to the handle 398 to operate the actuator 396, the seat bottom 326 will contact and apply a force to the detent 400 of the handle 398. This force will cause the detent 400 to flex away from the seat bottom 326, thereby allowing the handle 398 to retract into the seat back 324.

[0197] As shown, the handle 398 remains in the extended position not only during installation of the seat back 324 to the seat bottom 326, but also during separation of the seat back 324 from the seat bottom 326. In the extended position, the handle 398 is positioned vertically beneath not only the back portion 370 of the seat back 324, but also vertically beneath the bottom surface 351 of the seat bottom 326 (see FIGS. 19A-19B). The distal end 399 of the extended handle 398 will prevent the seat back 324 from sitting properly on a seating surface, such as of a vehicle seat for example. By designing the handle 398 to extend downward, beyond the bottom end 334 of the seat back 324 and the bottom 351 of the seat bottom 326, the lock pin actuator 396 prevents misuse of the seat back 324, such as the use of the seat back 324 as a seat when the seat back 324 is not connected to the seat bottom 326.

[0198] With reference to FIGS. 21 A-23B, in an embodiment, the seat back 324 includes at least one engagement tab 402a, 402b.
