[0162] A detailed description of one or more embodiments of the disclosed apparatus and methods is provided herein by way of example and not limitation with reference to the accompanying figures.

[0163] View now Figure 1 , an example of a child restraint system 20 is shown according to an embodiment. The child restraint system 20 includes a support base 22 that can be detachably fixed to the vehicle seat 10 (see Figure 2 and 3 ), such as via a latch or anchoring mechanism 502 (see Fig.47A ) for securing. Such latch or anchor systems that are often used are sometimes referred to as "lower anchors and tethers for children," for example, the LATCH system. Alternatively or in addition, as will be described in more detail below, the support base 22 can be removably secured to the vehicle seat 10 via a vehicle safety belt associated with the vehicle seat 10.

[0164] The child restraint system 20 additionally includes a rigid child seat 24 connected to the support base 22. In one embodiment, the child seat 24 is detachably coupled to the support base 22, thereby allowing the child seat 24 to be separated from the support base 22. Alternatively, the support base 22 and the child seat 24 can be permanently connected or attached together. As used herein, the term "permanently connected" refers to an embodiment in which it is not intended that the child seat 24 be detached from the support base 22 by a user.

[0165] The child seat 24 can include a seat shell 25 having a seat portion 26 and a backrest or upright portion 28 arranged at an angle relative to the seat portion 26. The seat portion 26 and the backrest portion 28 can be connected in a detachable manner, or alternatively, can be permanently connected. In the non-limiting embodiment shown, the seat portion 26 and the backrest portion 28 are integrally formed as a single body. In another alternative aspect, the backrest portion 28 can be connected to the seat portion 26 in a rotatable manner so that the backrest portion 28 can be tilted and reclined relative to the seat portion 26.

[0166] As shown, the back portion 28 of the child seat 24 includes an upright support surface 30 that faces generally forward and extends from a first end or top 32 of the upright portion to a second opposite end or bottom 34. A first upright side member 36 can be disposed at a first side 38 of the upright support surface 30, and a second upright side member 40 can be disposed at a second opposite side 42 of the upright support surface 30. Thus, the first upright side member 36 and the second upright side member 40 form left and right sides of the back portion 28, respectively. As shown, the first upright side member 36 and the second upright side member 40 extend forward from the upright support surface 30. The first upright side member 36 and the second upright side member 40 can extend generally orthogonal to the upright support surface 30, or alternatively, can extend therefrom at another angle, such as an angle greater than 90°. Thus, the upright support surface 30 and the first and second upright side members 36, 40 define a backrest area or upright support cavity 44 within which the upper body of a child is received.

[0167] In the non-limiting embodiment shown, the back portion 28 of the child seat 24 includes a headrest 46. The headrest 46 is attached to the back portion 28 or is integral with the back portion. The headrest 46 can be fixed or, in some embodiments, can be configured to move relative to the upright support surface 30. For example, the headrest 46 can be configured to translate between a retracted position and an extended position relative to the upright support surface 30, thereby allowing adjustment based on the size of the child positioned in the child seat 24. Figure 4A and 4B , a mechanism 45 for controlling the movement of a headrest 46 is shown. As shown, a ratchet or tooth 47 extending from a bracket 48 connected to the headrest 46 is spring biased into engagement with one of a plurality of openings 49 formed in an adjacent channel 51 mounted to the seat shell 25. This engagement between the tooth 47 and the corresponding opening 49 limits the movement of the headrest 46 relative to the seat shell 25. A user can apply a force to the bracket 48 to resist the bias of the tooth 47 and selectively disengage the tooth 47 from the opening 49, thereby allowing movement of the headrest between a plurality of positions.

[0168] exist Figures 29A to 29BIn another embodiment shown in FIG, the headrest 46 is again configured to engage one of a plurality of openings 49 formed in, for example, an adjacent channel 51 mounted to the seat shell 25. However, as shown, rather than being coupled to the bracket 48, a track 61 is coupled to the headrest 46 and movable therewith relative to the one or more channels 51. As shown, the headrest 46 itself may include a protrusion or hook 63 that cooperates with a portion of the headrest track 61 to couple the headrest track 61 to the headrest 46. As shown, the headrest track 61 may be trained between the surface of the headrest 46 and the hook 63.

[0169] View now Figures 39A to 44 , shows an example of a child restraint system 20 that includes an actuation mechanism 400 associated with movement of a headrest 46 relative to a child seat 24. The actuation mechanism 400 may include at least one link member 406a, 406b ( 406b ) arranged in alignment with a plurality of openings or slots 404 arranged at a seat back 408 of a seat shell 25. Fig.40A and 40B In one embodiment, the opening or slot 404 is located in the channel 402 at the seat shell 25 of the child seat 24 (see Fig.39B ). As shown, the actuation mechanism 400 includes a first link component 406a positionable near a first side 412 of a rear portion 410 of the headrest 46 and a second link component 406b disposed near a second opposing side 414 of the rear portion 410 of the headrest 46. However, embodiments including only a single link component or, alternatively, more than two link components are within the scope of the present invention.

[0170] The actuation mechanism 400 further includes an actuator 416, such as a handle, disposed on the exterior of the headrest 46 for user access. In the non-limiting embodiment shown, the actuator 416 is disposed at or near a top 418 of the headrest 46. The actuator 416 may be located at the front of the headrest ( Fig.39B ) or via the rear portion of the headrest 46 (see Fig.46 ) is reached. The at least one linking member 406a, 406b is operably coupled to the at least one actuator 416. As shown, a first end of each of the plurality of linking members 406a, 406b is connected to the actuator, or in some embodiments is integrally formed with the actuator.

[0171] A respective locking mechanism 420a, 420b may be associated with each link member 406a, 406b to selectively engage one or more of the plurality of openings 404 adjacent the channel 402. Thus, in the illustrated non-limiting embodiment, a first locking mechanism 420a is operably connected to the first link member 406a, and a second locking mechanism 420b may be operably connected to the second link member 406b.

[0172] Examples of corresponding locking mechanisms 420a, 420b are shown in Figures 41A to 43B . As shown, each locking mechanism 420a, 420b may include a first lock component 422, which is operably coupled to a second lock component 424. In the non-limiting embodiment shown, the second lock component 424 may be arranged at the distal end of the linking components 406a, 406b or formed integrally with the distal end. The first lock component 422 is movably coupled to the second lock component 424 and includes a feature 426 configured to engage a corresponding opening 404 of the channel 402. A biasing mechanism 428, such as a spring, may be configured to bias the first lock component 422 to engage one of a plurality of openings or slots 404 formed in an adjacent channel 402 mounted to the seat shell 25. This engagement between the first lock component 422 and the corresponding slot 404 limits the movement of the headrest 46 relative to the seat shell 25.

[0173] The first lock member 422 can be disengaged from the corresponding opening 404 in response to the application of the force F to the handle 416. Once disengaged, the headrest 46 can move relative to the child seat 24. When the user actuates the handle 416 of the headrest 46, the force F is applied to the at least one link member 406 operatively coupled to the handle, thereby causing the at least one link member 406 to change from a locked position to an unlocked position. This movement of the at least one link member 406a, 406b relative to the headrest 46 to the unlocked position resists the biasing force of the biasing mechanism 428.

[0174] In one embodiment, the movement of the second lock component 424 to the unlocked position will simultaneously cause the first lock component 422 to transition from the locked position (41A, 42A, 43A) to the unlocked position (41B, 42B, 43B), such as by applying a force to the actuator 416. Thus, the connection between the first lock component 422 and the second lock component 424 causes the first lock component 422 to be in the same configuration (locked or unlocked) as the second lock component 424. For example, when the first lock component 422 is in the locked configuration, the second lock component 424 is also in the locked configuration, and when the first lock component 422 is in the unlocked configuration, the second lock component 424 is also in the unlocked configuration.

[0175] An example of an interface between the first lock component 422 and the second lock component 424 is shown in FIG. Figures 41A to 41B 404. In the non-limiting embodiment shown, the second lock component 424 has a groove or recess 430 formed therein, such as at a location near the end 432 of the second lock component 424. The first lock component 422 may include a locking feature 434, such as a protrusion. The first lock component 422 may be pivotally mounted to the structure of the headrest 46 such that the locking feature 434 is disposed within the recess 430 formed in the second lock component 424. As the second lock component 424 moves vertically upward in response to the application of force to the actuator 416, the engagement between the locking feature 434 and the recess 430 will cause the first lock component 422 to pivot about its axis and disengage from the slot 404. Similarly, when the actuator 416 is released, the biasing force of the biasing mechanism 428 will apply a downward force to the second lock component 424 and the engagement between the locking feature 434 and the recess 430 will cause the first lock component 422 to pivot about its axis into engagement with the adjacent slot 404 .

[0176] However, in other embodiments, e.g. Figures 42A to 42B 4, the first lock component 424 can be pivotally mounted to the structure of the headrest 46 and pivotally directly coupled to the second lock component 424. In such embodiments, movement of the second lock component 424 in an upward direction toward the unlocked position will cause the first lock component 422 to pivot about two axes out of engagement with the slot 404. In addition, movement of the second lock component 424 driven downwardly toward the locked position by the biasing mechanism 428 will cause the first lock component 422 to pivot about two axes into engagement with the adjacent slot 404.

[0177] Another example of a locking mechanism, such as locking mechanism 420a or 420b, is Figures 43A to 43B 4. As shown in the figure, the second lock component 424 can have a slot 436 formed therein, and the first lock component 422 is slidably coupled to the second lock component 424 via the slot 436. When the second lock component 424 moves upward, the first lock component 422 is configured to translate relative to the second lock component 424 via the slot 436. Because the slot 436 is arranged at an oblique angle relative to the seat back 408, when the second lock component 424 moves upward, the first lock component 422 translates and disengages from the slot 404. When the second lock component 424 moves downward, for example, in response to the biasing force of the biasing mechanism 428, the first lock component 422 translates laterally into engagement with the corresponding slot 404. It should be understood that the various embodiments of the locking mechanisms 420a, 420b shown and described herein are intended to be examples only, and a locking mechanism having another configuration, for example, in which the first lock component 422 is configured to pivot and translate between a locked position and an unlocked position is within the scope of the present invention.

[0178] refer to Fig.24, one or more shock absorbers or side impact pods 250 designed to absorb forces in the event of an accident or collision may be disposed at the exterior of the seatback portion 28 of the seat shell 25. Although the side impact pods are shown as being disposed near the top 32 of the seatback portion 28, it will be appreciated that they may be positioned at any suitable location. In the non-limiting embodiment shown, a first side impact pod 250 wraps from the back surface 53 of the seatback portion 28 to the outer surface first upright side member 36, and a second substantially identical impact pod 250 wraps from the back surface 53 around the outer surface of the second upright side member 40. However, it will be appreciated that embodiments in which the impact pads 250 are positioned only at the back surface 53 or the upright side members 36, 40 are also covered herein. Continue to refer to Fig.24 , a recess 55 may be formed in the seat shell 25, such as in the seat back portion 28 of the seat shell 25. In the non-limiting embodiment shown, the recess 55 is formed in the back surface 53 and is sized to receive a command manual associated with the child restraint system 20.

[0179] As best shown in FIG. 23 , the seat portion 26 includes a seat support surface 50 that faces generally upward and extends from a first end or front portion 52 of the seat portion to a second end or rear portion 54. A first seat side component 56 may be disposed at a first side 58 of the seat support surface 50, and a second seat side component 60 may be disposed at a second, opposite side 62 of the seat support surface 50. The first seat side component 56 and the second seat side component 60 extend upward and extend from the left and right sides of the seat portion. The seat support surface 50 and the first seat side component 56 and the second seat side component 60 define in combination an area 64 within which at least a portion of the lower body of a child may be received.

[0180] As shown, the first seat side component 56 and the second seat side component 60 extend at an angle from the seat support surface 50. The angle of the first seat side component 56 relative to the seat support surface 50 may be the same as the angle of the first upright side component 36 relative to the upright support surface 30, but this need not be the case. Similarly, the angle of the second seat side component 60 relative to the seat support surface 50 may be the same as the angle of the second upright side component 40 relative to the upright support surface 30, but this need not be the case. In an embodiment, the first upright side component 36 and the first seat side component 56 are formed integrally, and the second upright side component 40 and the second seat side component 60 are formed integrally.

[0181] Although not generally shown, the child seat 24 additionally includes a harness assembly for restraining the child within the child seat 24. A typical harness assembly includes two shoulder straps that may be connected to at least one crotch strap via a buckle. Fig.26In one embodiment, an opening 69 formed in the seat portion 26 of the child seat 24 and associated with the crotch strap of the harness assembly can have a generally H shape. By configuring the opening 69 in the manner described, the crotch buckle can be easily adjusted between a forward position and a rearward position relative to the seat support surface 50.

[0182] The support base 22 for mounting the child seat 24 includes a base body having a base seat portion 72 and a base rear portion 74. Suitable materials for making the base body include, but are not limited to, rigid plastics or composite materials, for example. The base seat portion 72 and the base rear portion 74 may be integrally formed as a single body, or alternatively may be formed by separate components that are removably or permanently connected together. Figure 5 In the non-limiting embodiment shown, the support base 22 includes a first base member 76 having a bottom surface 78 suitable for placement on a support surface such as the vehicle seat 10, and a second base member 80 coupled to the first base member 76. In the non-limiting embodiment shown, at least a portion of the second base member 80 is positioned to overlap an upper surface 82 of the first base member 76. In the embodiment shown in the figures, the base rear portion 74 of the support base 22 is formed only by the second base member 80, and the base seat portion 72 of the support base 22 is formed by the first base member 76 and the second base member 80 in a combined manner.

[0183] refer to Figures 47A to 47B , the storage compartment 500 can be formed in a portion of the support base 22. Although the storage compartment 500 is shown as being formed only in the second base member 80, embodiments in which the storage compartment 500 is formed only in the first base member 76 or alternatively formed by the first base member 76 and the second base member 80 in combination are also within the scope of the present invention. In one embodiment, one or more latches 502 of a latch system for attaching the child seat system 20 to a vehicle seat can be retained within the storage compartment 500. As shown, the cover 504 can be in an open position ( Fig.47A ) and closed position ( Fig.47B ) to selectively seal the storage compartment 500. In one embodiment, the cover 504 is removable from the support base 22. However, in other embodiments, the cover 504 can be movably coupled, such as pivotally or hingedly coupled to the support base 22, so that the cover 504 remains attached to the support base when the cover 504 is in the open position and the closed position.

[0184] As shown, the child seat 24 can be directly attached to the second base member 80. For example, the base seat portion 72 of the second base member 80 can include a contour or opening 84 (see Figure 7) and the bottom end 86 of the child seat 24 is arranged in the opening 84. In one embodiment, as Fig. 6A and 6B , for example, a bottom end 86 of the child seat 24 disposed below the seat portion 26 of the child seat includes a flange 88 having an edge that is rolled or otherwise formed to form a rim or seat anchor 90. The second base member 80 may include one or more hooks or anchors 92 having a corresponding curvature configured to engage the rim 90. In one embodiment, as shown in FIG. Fig.27A 90 is a ring that is removably coupled to the bottom of the child seat 24 via at least one fastener and in some embodiments, multiple fasteners 91. Although eight screws are shown, it should be understood that any suitable fasteners or connectors are within the scope of the present invention. In addition, any number of fasteners or connectors, including a single fastener, two fasteners, three fasteners, four fasteners, five fasteners, six fasteners, seven fasteners, or more than eight fasteners, are contemplated herein. Alternatively or in addition, one or more pins 93 (see FIG. 1 ) embedded in the child seat 24 may be provided. Fig.27B ) can be used to attach the flange 88 to the child seat 24.

[0185] The child seat 24 can be rotated between a plurality of configurations relative to the support base 22. In one embodiment, the child seat 24 can be rotated relative to both the first base member 76 and the second base member 80 of the support base 22. For example, the engagement between the seat anchor 90 and the corresponding hook 92 formed on the second base member 80 can define a rotation path of the child seat 24 relative to the support base 22. As shown in the figure, the child seat 24 can be rotated between a first rotation configuration, such as where the child seat 24 is in a forward facing position ( Figure 2 ) configuration, wherein the second rotational configuration is, for example, where the child seat 24 is in a rearward facing position ( Figure 3 However, it should be understood that embodiments in which the child seat 24 can be positioned in one or more additional configurations between the first rotational configuration and the second rotational configuration are also within the scope of the present invention.

[0186] At least one base anchor member 94 can be fixedly connected to the base rear portion 74 of the support base 22. In the non-limiting embodiment shown, the base anchor member 94 is attached to the second base member near the distal end 96 of the second base member 80 and protrudes therefrom. The base anchor member 94 can be connected to a corresponding seat anchor member 98 of the child seat 24. Such a seat anchor member 98 is generally arranged at a surface of the seat back portion 28 of the child seat 24 (e.g., located behind the back of the child), and thus the base anchor member 94 can be connected to the seat anchor member when the child seat 24 is in a front-facing configuration. As will be described in more detail below, the base anchor member 94 can also be connected to the seat anchor member 98 regardless of the tilt angle of the child seat 24 relative to the support base 22. This connection between the base anchor member 94 and the seat anchor member 98 stabilizes the seat back portion 28 of the child seat 24. In such embodiments, the base anchor member 94 may not be connected to the seat anchor member 98 when the child seat 24 is in a face-rearward configuration. However, it should be appreciated that the base anchor component 94 may be adapted for use with seat anchor components disposed anywhere about the child seat 24 .

[0187] The child restraint system 20 may include a spin lock 100 operable to selectively lock the child seat 24 in one of the plurality of configurations relative to the support base 22. In the non-limiting embodiment shown, the spin lock 100 is disposed within the seat shell 25 of the child seat 24, such as within a portion of the end 86 that may be received within the support base 22. Figures 9 to 10B , the spin lock 100 includes a centrally located link 102 that is rotatable about an axis X. As shown, the link 102 can have two end segments 104 extending outwardly therefrom, such as disposed on opposite sides of the link 102 relative to the axis of rotation. A plurality of locking pins, such as two locking pins 106, are connected to the link 102. For example, a first end 108 of each locking pin 106 is connected to a corresponding end segment 104 of the link 102. As shown, the locking pins 106 can extend from the link 102 in opposite directions.

[0188] The locking pin 106 may be in a first locked position ( Fig. 10A ) and a second unlocked position in which the child seat 24 can rotate freely relative to the support base 22 ( Fig. 10B When each of the locking pins 106, and therefore the spin lock 100, is in the locked position, the second opposite end 110 of the locking pin 106 extends through an opening (not shown) formed in the seat shell 25 and engages with a corresponding lock segment 112 (see Figure 7) is engaged with, for example, a groove or slot formed in a portion of the support base. When the locking pin 106, and therefore the spin lock 100, is in the second unlocked position, the second end 110 of the locking pin 106 is separated from the lock segment 112, thereby allowing the child seat 24 to rotate relative to the second base component 80. In the non-limiting embodiment shown, the plurality of lock segments 112 are formed in the second base component 80. However, embodiments in which the plurality of lock segments 112 are formed in the first base component 76 are also contemplated herein.

[0189] In one embodiment, a biasing member (not shown), such as a torsion spring, is operably coupled to the link 102 to bias the link 102 and thus the locking pin 106 to a first locked position. At least one actuator 114 is operably coupled to at least one of the locking pins 106. In the non-limiting embodiment shown, a plurality of actuators 114 are operably coupled to the spin lock 100. As shown, a first actuator 114a is operably coupled to the first locking pin 106, and a second actuator 114b is operably coupled to the second locking pin 106. Each actuator 114a, 114b can be independently or individually operated to transform the locking pin 106 from a locked position to an unlocked position. Alternatively or in addition, the first actuator 114a and the second actuator 114b can be operated simultaneously to transform the locking pin 106 from a locked position to an unlocked position.

[0190] In the non-limiting embodiment shown, the one or more actuators 114a, 114b are substantially identical and include a handle 116 disposed at an outer surface of the child seat 24. The handle 116 may be directly or indirectly connected to the locking pin 106. In order to operate the actuators 114a, 114b to move the locking pin 106 to the unlocked position, a user applies a force to the handle 116. Although the handle 116 is shown as being pulled outward or pivoted when operated, embodiments in which the handle 116 moves in another manner, such as being pushed or pivoted inward, are also within the scope of the present invention. In response to the outward force applied to the handle 116, the actuator 114a applies an opposing force to the first locking pin 106 coupled thereto. The inward movement or translation of the first locking pin 106 causes the connecting rod 102 to rotate about its axis X in a first direction, thereby resisting the bias of the biasing member. Because the second locking pin 106 is also coupled to the link 102, rotation of the link 102 via the first locking pin 106 causes similar inward movement of the second locking pin 106. Via this inward movement, the second ends 110 of the two locking pins 106 disengage from the corresponding locking segments 112 of the support base 22. With the actuator 114a operated and the locking pins 106 disengaged from the locking segments 112, the user can then rotate the child seat 24 relative to the support base 22 to a desired rotational configuration.

[0191] Once the child seat 24 has reached the desired rotational configuration, the user will release the actuators 114a, 114b. Upon releasing the actuators 114a, 114b, the biasing force of the biasing member will cause the link 102 to rotate and the locking pin 106 to translate outward through the opening formed in the seat shell 25 and engage with the corresponding lock segment 112 associated with the rotational configuration of the child seat 24.

[0192] Reference Figures 11 to 12B , another example of a spin lock 100 is shown. In the non-limiting embodiment shown, the spin lock 100 includes a plurality of lock components, such as a first lock component 120 pivotally mounted near a first side of the seat shell 25, and a second substantially identical lock component 120 pivotally mounted near a second opposite side of the seat shell 25. Each lock component 120 has a first connector 122 and a second connector 124 extending in different directions from a first inwardly facing side 126 of the lock component 120. A first linking belt 128 extends between and connects the first connector 122 of the first lock component 120 and the second connector 124 of the second lock component 120. Similarly, a second linking belt 128 extends between and connects the second connector 124 of the first lock component 120 and the first connector 122 of the second lock component 120.

[0193] The lock member 120 may be in a first locked position ( Fig. 12A ) and a second unlocked position in which the child seat 24 can rotate freely relative to the support base 22 ( Fig. 12B ). When each of the lock components 120 is in the locked position, a locking pin 130 protruding from a second or outwardly facing surface 131 thereof extends through an opening (not shown) formed in the seat shell 25 and engages with a corresponding locking segment 112, such as a recess or slot formed in a portion of the support base 22. As described with respect to the previous embodiment or the spin lock 100, the locking segment 112 may, but need not, be formed in the second base component 80. When the lock components 120 are in the second, unlocked position, the locking pin 130 is disengaged from the locking segment 112, thereby allowing the child seat 24 to rotate.

[0194] A biasing member, such as a torsion spring, is operably coupled to at least one or each of the lock members 120 to bias each lock member 120 about its axis to a locked position. Similar to the previous embodiment, an actuator 114a, 114b, such as a handle 116, is operably coupled to each lock member 120, respectively. The first actuator 114a may be operably coupled to the first lock member 120, and the second actuator 114b may be operably coupled to the second lock member 120. Furthermore, each actuator 114a, 114b may be independently operable, or alternatively or additionally, the actuators 114a, 114b may be operated in unison to transform the lock pin 130 from the locked position to the unlocked position.

[0195] In order to unlock the child seat 24, the user applies a force, such as an outward force, to the handle 116 of the actuator 114a, 114b. However, it should be understood that the spin lock 100 can be adapted to another type of movement of the actuator 114. The first lock component 120 is configured to rotate around its axis in response to the operation of the first actuator 114a. This rotation causes the lock pin 130 to rotate inwardly away from the lock section 112, and the opposite part of the lock component 120 rotates outwardly. The connection between the first lock component and the second lock component 120 via the plurality of link belts 128 applies a similar rotational force to the second lock component 120. In the non-limiting embodiment shown, the first connector 122 is positioned near the first end 132 of the lock component 120, and the second connector 124 is positioned near the second end 134 of the lock component 120 and the lock pin 130. Therefore, when the actuator 114a is operated, the first connector 122 rotates outwardly, thereby applying a force to the second connector 124 of the second lock component 120 via the first link belt 128. This force acting on the second connector 124 of the second lock component 120 causes the second lock component 120 to pivot about its axis, thereby disengaging the lock pin 130 from the corresponding lock segment 112. With the actuator 114a operated and the lock pin 130 disengaged from the lock segment 112, the user can then rotate the child seat 24 relative to the support base to a desired rotational configuration.

[0196] Once the child seat 24 has reached the desired rotational configuration, the user will release the actuator 114a. Upon releasing the actuator 114a, the biasing force of the biasing member will cause the first lock member 120 to pivot about its axis to a locked position. In response to this rotation, the second connector 124 of the first lock member 120 transmits a force to the first connector 122 of the second lock member 120. This force pulls the first end 132 of the second lock member 120 inwardly, thereby causing the locking pin 130 of the second lock member 120 to rotate outwardly and engage with the adjacent lock segment 112 associated with the position of the child seat 24. It should be understood that the various configurations of the spin lock 100 shown and described herein are intended to be examples only, and any mechanism suitable for selectively locking and unlocking the rotation of the child seat 24 relative to the support base 22 about an axis is within the scope of the present invention.

[0197] Reference Figures 13 to 15 , showing an alternative embodiment of the spin lock 100. In a non-limiting embodiment, the spin lock 100 is substantially the same as that of Figures 9 to 10B The spin lock shown and described; however, unlike Figures 9 to 10B In the embodiment shown in FIG. 1 , the axis of rotation X of the link 102 is coaxial with the axis of rotation of the child seat 24 relative to the support base 22. It should be appreciated that embodiments in which these axes are offset from one another, such as in FIG. Figures 9 to 10B It is also within the scope of the present invention.

[0198] Another example of spin lock 300 is Figures 48 to 51 . Similar to the previous embodiments, the spin lock 300 is arranged in the seat shell 25 of the child seat 24, for example, can be received in the portion of the end 86 in the support base 22. As shown, the spin lock 300 includes a centrally located connecting rod 302 that can rotate or pivot around the axis X. The connecting rod 302 can be attached to the support base 22 via any suitable connection mechanism such as a pin or a bolt that allows the connecting rod 302 to freely spin around its axis. As shown, the connecting rod 302 can have two end segments 304 extending outwardly therefrom, for example, disposed on opposite sides of the connecting rod 302 relative to the axis of rotation. At least one locking pin, for example, two locking pins 306, are connected to the connecting rod 302. For example, the first end 308 of each locking pin 306 is connected to the corresponding end segment 304 of the connecting rod 302. As shown, the locking pins 306 can extend from the connecting rod 302 in opposite directions. Although the spin lock 300 is shown and described as having two locking pins, embodiments in which the link 302 includes a single end segment 304 and / or only a single lock component 306 is operably coupled to the link 302 are also within the scope of the present invention.

[0199] Similar to the previously described embodiments, the locking pin 306 may be in a first locked position ( 104 ) in which the child seat 24 cannot rotate relative to the support base 22. Fig.49A ) and a second unlocked position in which the child seat 24 can rotate freely relative to the support base 22 ( Fig.49B When each of the locking pins 306 and thus the spin lock 300 is in the locked position, the second opposite end 310 of the locking pin 306, such as a boss disposed at the second end of the locking pin 306, extends through an opening (not shown) formed in the seat shell 25 and engages with a corresponding lock opening 312 (see Fig.51 ) is engaged with, for example, a groove or slot formed in a portion of the support base. When the locking pin 306, and therefore the spin lock 300, is in the second unlocked position, the second end or boss 310 of the locking pin 306 is disengaged from the lock opening 312, thereby allowing the child seat 24 to rotate relative to the second base member 80. In the non-limiting embodiment shown, the plurality of lock openings 312 are formed in the second base member 80. However, embodiments in which the plurality of lock openings 312 are formed in the first base member 76 are also contemplated herein. Although not shown, a biasing member (not shown), such as a torsion spring, may be operably coupled to the link 302 to bias the link 302, and therefore the locking pin 306, to the first locked position.

[0200] An actuator 314 is associated with at least one of the locking pins 306. Figures 48 to 51 In the non-limiting embodiment shown in FIG. 3 , the spin lock 300 includes a corresponding actuator 314 operably coupled to each of the locking pins 306. As shown, the actuator 314 can be integrally formed with the lock member 306 so that the actuator 314 and the locking pin 306 are a single body. The actuator 314 can be arranged near the second end 310 of the locking pin 306 and can extend at an angle relative to it. Although the actuator 314 is shown as being arranged vertically above the locking pin 306, embodiments in which the actuator 314 is at another position relative to the locking pin 306, such as at one side of the locking pin 306, are also covered herein. The outwardly facing surface 316 of the actuator 314 can be vertically aligned with the second end 310 of the locking pin 306. In other embodiments, the outwardly facing surface 316 can be spaced farther apart from the axis of the connecting rod 302 than the second end 310. The actuator 314 is disposed within, and in some embodiments extends through, an opening 320 formed in the seat base 26 . The actuator and the locking pin 306 can move in the same direction, such as the actuation direction, to selectively disengage the boss 310 from the corresponding locking opening 312 .

[0201] When a force is applied to the actuator 314, for example, in a direction toward the interior of the child seat 24, the actuator 314 and the locking pin 306 together translate laterally toward the axis. This translation causes the boss 310 of the locking pin 306 to disengage from the corresponding lock opening 312 formed in the support base 22, and causes the connecting member 302 to rotate about its axis. Because the locking members 306 are symmetrically attached to the connecting member 302, the actuation of one locking pin 306 causes the serial movement of the plurality of locking members 306. Once the locking pin 306 is separated from the support base 22, the user can spin or rotate the child seat 24 relative to the support base 22. Once the child seat 24 is in the desired rotational position, the force applied to the actuator 314 is released. In response to the removal of the force, a biasing mechanism (not shown) operably coupled to the connecting member 302 biases the connecting member 302 about its axis and biases the locking pin 306 into an engaged position to re-lock the child seat 24 to the support base 22. When the actuator 314 of the spin lock 300 is not depressed, the biasing force of the biasing mechanism prevents the child seat 24 from rotating.

[0202] However, it should be understood that embodiments in which the actuator 314 is arranged at another location around the child seat 24, such as near the front of the child seat 24, are also within the scope of the present invention. In such embodiments, the actuator can be directly or indirectly coupled to the lock pin 306. In embodiments in which the actuator 314 is arranged near the front of the child seat, such as near the feet of the passenger, the position of the actuator 314 and / or the biasing force of the biasing mechanism associated with the connecting member 302 can be sufficient to prevent accidental unlocking of the spin lock 300 if the passenger kicks the actuator 314.

[0203] refer to Figures 15 to 17B In one embodiment, the spin lock 100 can additionally provide a visual indicator 200 to an operator of the child restraint system 20 to indicate whether a lock component, such as component 106 or 120, is engaged with the support base 22 so that the child seat 24 is locked from rotating relative to the support base 22, or whether the lock component 106, 120 is disengaged from the support base 22, thereby allowing the child seat 24 to rotate. The visual indicator 200 is associated with the spin lock 100. In one embodiment, the visual indicator 200 is operably coupled to a portion of the spin lock 100, such as the lock component 106, and is arranged in general alignment with a window 202 formed in a portion of the support base 22. A portion of the lock component 106 can be configured to contact and apply a force to the visual indicator 200, such as when the lock component 106 moves from an engaged or locked position to a disengaged or unlocked position. However, embodiments in which the visual indicator 200 is movably coupled to a portion of the lock component 106 or is formed integrally therewith are also within the scope of the present invention.

[0204] In the non-limiting embodiment shown, the indicator 200 includes, for example, a first indicator segment 204 having a first color that is operable to indicate that the child seat 24 is rotatably locked to the support base 22, and a second indicator segment 206 having a different color that is operable to indicate that the child seat 24 is freely rotatable relative to the support base 22. Alternatively or in addition, the indicator 200 may include alphanumeric characters, such as the words locked or unlocked, or some other symbol to represent one or both of these conditions, respectively.

[0205] As shown, the indicator 200 can be movably mounted to a wiper blade 208 aligned with the lock member 106. In the non-limiting embodiment shown, the wiper blade 208 is rotatably mounted to the support base 22 via a pin 210. A biasing member 212, such as a torsion spring, is operably coupled to the wiper blade 208, and the biasing force of the biasing member 212 can bias the indicator 200 to a second position in which the second indicator segment 206 is aligned with the window 202 ( Fig.16A ). As best shown in the figure, when the lock member 106 is in the locked position, a portion of the lock member 106 is operable to engage at least one of the wiper blade 208 and the indicator 200. The force applied by the lock member 106 to the wiper blade 208 or the indicator 200 resists the biasing force of the biasing member 212, thereby maintaining the indicator 200 in a position in which the first indicator section 204 is aligned with the window 202.

[0206] When the user applies force to the handle 116 of the actuator 114 to release the spin lock 100, the lock member 106 moves, e.g., translates, out of engagement with the indicator 200 and / or the wiper blade 208. Thus, the biasing force of the biasing member 212 will bias the wiper blade 208 and the indicator 200 to a position where the second indicator section 206 of the indicator 200 is aligned with the window 202 ( Fig. 16B Once the force is released from the handle 116, the biasing member associated with the spin lock 100 will bias the lock member 106 toward the locked position and engage the indicator 200 and / or the wiper 208 as previously described.

[0207] Reference Figures 17A to 17B , shows an indicator according to another embodiment of the child restraint system 20. As shown, the support base 22 includes a window 202 associated with the indicator 200. When the child seat 24 is rotatably locked to the support base 22, the plunger 220 extends through the window 202 ( Fig.17A). The plunger 220 may be part of the lock component 106 or may be a separate component movably coupled thereto. The portion of the plunger 220 visible at the window 202 may have a first color or alphanumeric marking or symbol 222 to indicate that the spinlock 100 is engaged. When the spinlock 100 is locked, the plunger 220 may overlap with the second indicator 224, thereby preventing the second indicator from being visible through the window 202. When the handle 116 of the actuator 114 is operated and the lock component 106 of the spinlock 100 is in the unlocked position, the plunger 220 may move, e.g., retract, and thus not be present within the window 202. In fact, as Fig. 17B As shown, in the absence of the plunger 220 , the portion of the support base 22 visible through the window 202 has a second color or alphanumeric marking or symbol 224 and thus acts as a second indicator 224 to indicate that the spin lock 100 is disengaged and the child seat 24 is free to rotate.

[0208] refer to Fig.28 In one embodiment, for example, a handle 116 of an actuator 114 associated with the spin lock 100 includes a secondary lock 136 operably coupled thereto. In the illustrated non-limiting embodiment, the secondary lock 136 includes a member 138 that is movable to selectively disengage the support base 22. For example, the member 138 may include a protrusion that is receivable within a corresponding groove or recess formed in the support base 22. As shown, the secondary lock 136 may be mounted to the handle 116 to prevent it from being inadvertently actuated, and thus prevent the spin lock 100 from being released. In such embodiments, a user must first unlock the secondary lock 136, for example, by sliding the member 138 away from or out of engagement with the support base 22, and then operate the actuator 114 by applying a force to the handle 116. A biasing mechanism, not shown, may be coupled to the secondary lock to bias the secondary lock into engagement with the support base 22, thereby locking the actuator 114.

[0209] 18 to 21B, the child seat 24 may alternatively or additionally be moved relative to the support base 22 to adjust the inclination of the child seat 24. The child seat 24 may be positioned along an upright position ( Fig.21A ) and, for example, the rearward position ( Fig. 21B ) and a second position. However, it should be understood that both the first position and the second position can be inclined positions having different degrees of inclination. In addition, embodiments in which the child seat 24 can be arranged in any of a plurality of positions between the upright position and the reclined position are also contemplated herein (see, for example, the discussion below). Fig.31A to C).

[0210] In one embodiment, the second base member 80 and the child seat 24 coupled thereto can be translated relative to the first base member 76 to control the tilt or recline of the child seat 24. As shown, a recline lock mechanism 140 can be mounted to the second base member 80. In the non-limiting embodiment shown, the recline lock mechanism 140 includes a centrally located pivot link 142 that can rotate about an axis. As shown, the pivot link 142 can have two end segments 144 extending outwardly therefrom, such as disposed on opposite sides of the pivot link 142 relative to its axis of rotation. At least one recline pin, such as two recline pins 146, is connected to the pivot link 142 via a corresponding connector 148. In the non-limiting embodiment shown, the connector 148 is pivotally coupled to the pivot link 142 and can be translated relative to the recline pin 146. For example, the recline pin 146 can have an elongated slot 150 formed therein, and the connector 148 can have a pin or post 152 disposed within the slot 150. As shown, the connector 148 and the rearward caster pin 146 may extend from the pivot link 142 in opposite directions.

[0211] The plurality of rearward dump pins 146 may be uniformly positioned in a first locked position ( 144 ) in which the second base member 80 is not movable relative to the first base member 76. Fig.21A ) and a second unlocked position ( ) in which the second base member 80 and therefore the child seat 24 rotatably coupled to the second base member 80 can freely move relative to the first base member 76 to adjust the tilt of the second base member 80 and the child seat 24 Fig. 21B ). When each of the rearward tilt pins 146 is in the locked position, the second end 154 of the rearward tilt pin 146 extends through an opening formed in the second base component 80 and engages with a corresponding lock opening 156 formed in a portion of the first base component 76 (e.g., a side wall thereof). When the rearward tilt pins 146 are in the second unlocked position, the second ends 154 of the rearward tilt pins 146 are separated or disengaged from the lock openings 156, thereby allowing the second base component 80 and the child seat 24 to tilt or recline.

[0212] In one embodiment, a biasing member 157, such as a coil spring, is operably coupled to each of the rearward tilt pin 146 and the connector 148, and is operable to bias the rearward tilt pin 146 to a first locked position via movement of the connector 148. In other embodiments, the biasing member may be operably coupled to the pivot link 142. An actuator 160 is operably coupled to the rearward tilt lock mechanism 140. In the non-limiting embodiment shown, the pivot link 142 includes a radially extending actuation tab 158, and the actuator 160 includes a handle 162 disposed at an outer surface of the support base 22. The handle 162 is coupled to the actuation tab 158 via a linkage mechanism or a cable 164. The application of force to the handle 162 can be used to rotate the pivot link 142 about its axis. This rotation will apply force to the rearward tilt pin 146, thereby causing the pin 152 of the connector 148 to translate in the slot 150 formed in the rearward tilt pin 146. In response to this movement of the pin 152, a force is applied to the biasing member 157 to resist its bias. Movement of the connector 148 will result in corresponding movement of the rearward tilt pin 146 from the locked position to the unlocked position. While the rearward tilt pin 146 is maintained in the unlocked position via the application of force to the handle 162, the second base member 80 can translate relative to the first base member 76. Fig. 20 , the first base member 76 includes a plurality of lock openings 156, each associated with a different tilt of the child seat 24. The second base member 80 can thus be moved to a position in which the tip 154 ​​of the rearward tilt pin 146 is aligned with and configured to engage a corresponding one of the plurality of lock openings 156. It should be appreciated that the rearward tilt lock mechanism 140 shown and described herein is intended only as an example, and any mechanism suitable for selectively locking and unlocking the child seat 24 and / or movement of the second base member 80 relative to the first base member 76 to adjust the tilt of the child seat 24 is within the scope of the present invention.

[0213] refer to Figures 30A to 31C, a recline indicator 166 can be provided to indicate the current recline position of the child seat 24. In the non-limiting embodiment shown, the recline indicator 166 includes a plurality of first marks 167 and a second mark 168. Each of the plurality of first marks 167 can be selectively positioned relative to the second mark 168 to indicate the corresponding recline position of the child seat 24. The plurality of first marks 167 are spaced apart from each other so that each first mark 167 can be aligned with the second mark 168 in a particular recline position due to the translational movement of the second base member 80 relative to the first base member 76. It will be appreciated that four discrete recline positions are shown, but various other numbers of discrete positions can be provided. In some embodiments, a continuous range of positions can be indicated. As shown, the base seat portion 72 of the support base 22 includes the plurality of first marks 167, and the first base member 76 includes the second mark 168. However, it should be understood that embodiments in which a single first mark 167 is disposed at the base seat portion 72 and the first base member 76 includes a plurality of second marks 168 are also within the scope of the present invention.

[0214] Reference Figure 7 , 8A 8B, 22A to 23B, 35 and 36A to B, in one embodiment, the support base 22 includes a seat belt tensioner 170. In the non-limiting embodiment shown, an opening 172 is formed in the base rear portion 74 of the support base 22, and the seat belt tensioner 170 can be received within the opening 172. The contour of the seat belt tensioner 170 can be complementary to the contour of the opening 172 so that a substantial portion of the seat belt tensioner 170 can be received within the opening 172. The vehicle seat belt 12 (see FIG. 1 ) associated with the vehicle seat 10 on which the support base 22 can be positioned Fig. 22B ) can be positioned along a seat belt storage path defined between a surface 174 of the base rear portion 74 of the support base 22 and the seat belt tensioner 170. In one embodiment, the seat belt tensioner 170 includes a frame 171 having an actuator 173 mounted to the frame 171. The actuator 173 can be operable to selectively release or disengage a corresponding engagement member of the frame 171 from a strip or other connector 175 disposed within the opening 172. Fig. 8A and 8B In the illustrated non-limiting embodiment shown in , the front surface or face of the actuator 173 has a generally circular profile.

[0215] In one embodiment, the seat belt tensioner 170 can be selectively moved relative to the support base 22 to adjust the tension applied to the vehicle seat belt 12 along the vehicle seat belt storage path. For example, the seat belt tensioner 170 can be configured to be in the open position ( Figure 7 , 22Aand 22B) with closed position ( Figure 2 and 3 ) pivots about at least one axis between the support base 22 and the vehicle seat 10 to selectively pinch or tension the portion of the vehicle seat belt 12 that is sandwiched between the seat belt tensioner 170 and the opening 172 to connect the support base 22 to the vehicle seat belt 12, thereby limiting the movement of the support base 22 relative to the vehicle seat 10.

[0216] Reference Figures 35 to 36B In some embodiments, the vehicle seat belt 12 can be pressed against or between various features of the seat belt tensioner 170 and / or the base rear portion 74 of the support base 22 to provide additional tension and / or friction to prevent the vehicle seat belt 12 from sliding relative to the support base 22. In one embodiment, as shown in FIG. Fig.36A As shown in FIG. 1B , the belt tensioner 170 may include one or more tensioner ribs 171a to 171d protruding from the belt tensioner 170 toward and into the opening 172. In embodiments including a plurality of tensioner ribs 171a to 171d, the ribs may extend different axial lengths from the surface of the belt tensioner 170. The base rear portion 74 may provide one or more features at or within the opening 172. In the non-limiting embodiment shown, the at least one feature includes a plurality of rear ribs 173a to e. The rear ribs 173a to e may include corner ribs 173b, 173d, and / or a center rib 173c. The surface 174 of the base rear portion 74 may additionally or alternatively provide one or more features at or near the opening 172, such as a first surface corner 174a and a second surface corner 174b. The first corner 174a and the second corner 174b may define a variable surface complementary to the different axial lengths of the tensioner ribs 171a to 171d. Therefore, when the seat belt tensioner 170 is closed and received in the opening 172, as shown in FIG. Fig.36A As shown, the vehicle safety belt 12 is forced to change direction along a circuitous or convoluted path defined between the tensioner ribs 171a to 171d, the first corner 174a and the second corner 174b and one or more central rear ribs 173a to 173e. In addition, the vehicle safety belt 12 is pinched or tensioned at multiple locations along the circuitous path.

[0217] In one embodiment, if Fig. 22BAs best shown in , one or more seat belt guides 176 can be positioned about the support base 22, such as the base rear portion 74 thereof. As shown, the seat belt guide 176 can include a narrow slot 178 for receiving a portion of the vehicle seat belt 12 therein. Although substantially identical seat belt guides 176 are shown as being arranged at opposing sides of the base rear portion 74, it should be understood that embodiments having a single seat belt guide are within the scope of the present invention. Moreover, in embodiments that include multiple seat belt guides 176, the seat belt guides can have different configurations and / or can be arranged at different vertical and lateral positions relative to the support base 22 based on the vehicle seat belt path. Figures 23A to 23B In the non-limiting embodiment shown in , the seat belt guide 176 can be mounted to the support base 22, such as via a seat belt path insert 177 mounted to the surface of the base rear portion 74. The seat belt path insert 177 can be permanently or removably attached to the support base 22, and the seat belt guide 176 can be permanently or removably connected to the seat belt path insert 177. The inclusion of the seat belt path insert 177 allows the seat belt guide 176 to be located at a position laterally offset from the base rear portion 74.

[0218] refer to Fig.37A 38A to C and 38A to C, in some embodiments, a seat belt guide 176 can be provided at a lower region of the support base 22, such as near the interface between the base rear portion 74 and the base seat portion 72. The seat belt guide 176 can be arranged to receive the leg strap of the vehicle seat belt 12. One or more corrugated regions 176A, 176B can be provided on the surface of the base rear portion 74, such as corrugated regions 176A on the side surface and corrugated regions 176B on the side surface and bottom surface. The corrugated regions 176A, 176B are arranged to receive the vehicle seat belt 12 and further guide the vehicle seat belt around the support base 22. As shown in FIG. Fig.38A As shown in Figure 3C, a plurality of ribs 182 may be provided in this area of ​​the support base 22 to provide additional rigidity and strength in the event that the vehicle seat belt 12 is pressed against the support base 22. In some embodiments, a bottom cover 184 may be provided and contain a portion of the ribs 182 in a complementary arrangement to provide a rigid structure when assembled with the support base 22.

[0219] refer to Fig.24In one embodiment, a notch or cutout 180 is formed at the front edge 52 of the child seat 24. In order to use the belt tensioner 170 to attach the support base 22 to the vehicle seat 10 via the vehicle seat belt 12, the child seat 24 is rotated relative to the support base 22 to a rearward-facing configuration. In the rearward-facing configuration, the notch is aligned with the belt tensioner 170 and the corresponding opening 172, so that when the belt tensioner is open or separated from the opening 172, the belt tensioner 170 is disposed within the notch 180 formed in the child seat 24. Thus, when the belt tensioner 170 is positioned within the notch 180, the belt tensioner 170 interferes with and limits the rotation of the child seat 24 relative to the support base 22. Only once the belt tensioner 170 has been closed or stowed within the opening 172 can the child seat 24 be transformed from the rearward-facing configuration to another configuration.

[0220] In one embodiment, the tension applied to the vehicle belt 12 by the belt tensioner 170 depends on the position of the second base member 80 relative to the first base member 76, and therefore on the tilt of the child seat 24. Thus, in one embodiment, the child seat 24 can be in a reclined or at least partially reclined position when the vehicle belt 12 is coupled to the support base 22 via the belt tensioner 170. During installation of the support base 22 about the vehicle seat 10, after the belt tensioner 170 has applied initial tension to the vehicle belt 12, the tilt of the child seat 24 is then adjusted to increase the tension of the vehicle belt 12. While the child seat 24 is in any suitable rotational configuration relative to the support base 22, the recline lock mechanism 140 coupling the second base member 80 to the first base member 76 can be unlocked and the tilt of the child seat 24 can be adjusted, for example, to increase. As the second base member 80 and the child seat 24 translate relative to the first base member 76, the corresponding movement of the belt tensioner 170 increases the tension on the vehicle belt 12.

[0221] The first seat side member 56 and the second seat side member 60 can form an armrest for a child seated in the child seat 24. In some embodiments, a cup holder 230 can be located near one end of at least one of the first seat side member 56 and the second seat side member 60, such as closest to the front portion 52 of the seat support surface. These cup holders 230 can be fixed, or in some embodiments, can rotate relative to the seat shell 25 while remaining attached thereto. The rotatable cup holders 230 can: 1) provide easy access to the cup holders 230 for a child seated in the child seat 24, 2) move to a position to allow the child to more easily enter and exit the seat 24, 3) move to a position to minimize any interference of the cup holders 230 with the seat 24 and the support base 22 during rotation of the seat 24, and 4) move to a position to minimize the overall size (e.g., packaging) of the child restraint system 20 for packaging, shipping, and placement of the system 20, for example.

[0222] refer to Figures 32A to 33 , the cup holder 230 is rotatable and configured to maintain discrete positions, for example, to prevent accidental movement of the cup holder during transport or use. In the illustrated embodiment, the cup holder 230 rotates about a pivot member 232 mounted with the child seat 24. In one embodiment, the cup holder 230 includes a stopper 234, for example, disposed at a bottom surface thereof, and the child seat 24 includes a plurality of recesses 236 in which the stopper 234 can be received. The plurality of recesses 236 can be arranged to define a plurality of different positions of the cup holder 230 relative to the child seat 24. The engagement between the stopper 234 and a corresponding recess 236 in the plurality of recesses can hold the cup holder 230 in the position. There may be a resilient resiliency in one or both of the stopper 234 and the material defining the recess 236, so that the stopper 234 can be disengaged from the recess 236 when sufficient force is applied. Once the stopper 234 is separated from the recess 236, the cup holder 230 is free to rotate about its pivot axis. In some embodiments, the pivot member 232 may be removed from the child seat 24 to allow removal of the cup holder 230 .

[0223] like Fig.33 As shown, the rotation of the cup holder 230 can be limited to a desired range. In the non-limiting embodiment shown, the cup holder 230 includes a tab 238 on the opposite side of the pivot member 232. The child seat 24 can include a recess defined by the side walls 240A, 240B. The tab 238 and the side walls 240A, 240B are sized to allow a desired range of rotation, but the engagement between the tab 238 and one or more of the side walls 240A, 240B prevents any further rotation. Therefore, the side walls 240A, 240B can act as a rotation limiting stop.

[0224] refer to Figures 34A to 34CIn some embodiments, the child seat 24 may include a seat pan 190 having a bottom surface 191 in its bottom portion for supporting a child and providing a shape for textiles. The child seat 24 may also include at least one seat cushion 192A, 192B. As shown, the seat cushions 192A, 192B may extend upward from the bottom surface 191 of the seat pan 190, close to the top of the corresponding first seat side component 56 and the second seat side component 60. In an embodiment, the seat cushions 192A, 192B terminate below the first seat side component 56 and the second seat side component 60 of the back portion 28 of the seat shell 25. In some embodiments, the seat cushions 192A, 192B gradually narrow in thickness as they extend toward the front of the child seat 24. The seat cushions 192A, 192B may also gradually narrow in thickness as they extend upward from the seat pan 190. The seat cushions 192A, 192B are shown as being integrally formed from the same material as the seat pan 190; however, in other embodiments, the seat cushions 192A, 192B may be separate portions from the seat pan.

[0225] Seat cushions 192A, 192B are arranged inside the first seat side component 56 and the second seat side component 60 to reduce the sitting width of a part of the child seat 24, thereby improving the side impact protection performance when protecting the child passenger. The seat cushions 192A, 192B of the illustrated embodiment are sized and positioned to reduce the sitting width in the general area of ​​one or more of the buttocks, legs and lower back of the passenger. This position substantially reduces or substantially eliminates the lateral movement of the child's body during the side impact event. Other positions or position combinations for seat cushions 192A, 192B are expected to be included in the cushions on only one side of the seat bottom plate 190. In addition, one or two of the seat cushions 192A, 192B can be removable to accommodate children of different sizes. The child restraint system 20 as described herein allows the rotation configuration and tilt of the child seat 24 to be adjusted relative to the support base 22 and the vehicle seat 10. The seat cushions 192A, 192B can be formed by various materials, including foam or other materials used elsewhere in the child seat 24. In some embodiments, the seat cushions 192A, 192B are structural components of the child seat 24. The seat cushions 192A, 192B can be formed from a substantially or essentially rigid material or a semi-rigid material (e.g., a hard plastic or foam material that may be used in a seat shell or headrest), as opposed to materials of conventional car seat inserts that are made of, for example, fabrics and soft, deformable foams without any internal rigid structure.

[0226] Reference Figures 45A to 45CAs previously described, the child seat 24 includes: a rear portion 28 including an upright support surface shown at 408, a first upright side member 36 extending from a first side 38 of the upright support surface 408, and a second upright side member 40 extending from a second side 42 of the upright support surface 408. As shown, one or more reinforcement members 600 can be arranged around the child seat 24, such as at the rear portion 28. In the non-limiting embodiment shown, the at least one reinforcement member 600 is arranged at an outer surface of at least one upright side member 36, 40. The reinforcement member 600 can extend from a location near the interface with the adjacent seat side members 56, 60 toward the top 32 of the rear portion 28. In addition, the reinforcement member 600 can span substantially the entire distance of the side members 36, 40 between the rear surface and the forward-facing ends 602, 604 of the upright side members 36, 40. The inclusion of this reinforcement member 600 at the rear portion 28 of the seat shell 25 can help manage soft goods (not shown) attached to the child seat 24. Alternatively or additionally, the reinforcement member 600 may absorb or redistribute forces applied to the sides of the child seat 24 , thereby improving the crash performance of the child seat 24 , including side impact performance.
