[0164] This document provides a detailed description of one or more embodiments of the disclosed apparatus and methods by way of example and not limitation, with reference to the accompanying drawings.

[0165] Now see 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, which can be detachably fixed to the vehicle seat 10 (see [reference]). Figure 2 and 3 ), for example via latch or anchoring mechanism 502 (see Figure 47A The latch or anchoring system is often referred to as a “lower anchor and tether for children,” for example, a latch system. Alternatively or additionally, as will be described in more detail below, the support base 22 can be removably secured to the vehicle seat 10 via a vehicle seat belt associated with the vehicle seat 10.

[0166] The child restraint system 20 further includes a rigid child seat 24 attached to a support base 22. In one embodiment, the child seat 24 is detachably attached 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 may be permanently attached or attached together. As used herein, the term "permanently attached" refers to embodiments where it is not intended for the user to detach the child seat 24 from the support base 22.

[0167] The child seat 24 may include a seat housing 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 may be detachably connected, or alternatively, permanently connected. In the illustrated non-limiting embodiment, the seat portion 26 and the backrest portion 28 are integrally formed as a single body. In another alternative aspect, the backrest portion 28 may be rotatably connected to the seat portion 26, such that the backrest portion 28 can tilt and recline relative to the seat portion 26.

[0168] As shown, the backrest portion 28 of the child seat 24 includes an upright support surface 30, which generally faces 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 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. Thus, the first upright side member 36 and the second upright side member 40 form the left and right sides of the backrest 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 may extend generally orthogonally to the upright support surface 30, or alternatively, may extend from it at an angle, for example, greater than 90°. Therefore, the upright support surface 30 and the first upright side component 36 and the second upright side component 40 define the backrest area or upright support cavity 44, which accommodates the upper body of a child.

[0169] In the illustrated non-limiting embodiment, the backrest portion 28 of the child seat 24 includes a headrest 46. The headrest 46 is attached to the backrest portion 28 or integral with the backrest. The headrest 46 may be fixed, or in some embodiments, it 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 retracted position and an extended position, thereby allowing adjustment based on the size of the child positioned within the child seat 24. Reference Figure 4A and 4BThe diagram illustrates a mechanism 45 for controlling the movement of the headrest 46. As shown, a ratchet or tooth 47 extending from a bracket 48 attached to the headrest 46 is spring-biased to engage one of a plurality of openings 49 formed in an adjacent channel 51 mounted to the seat housing 25. This engagement between the tooth 47 and the corresponding opening 49 restricts movement of the headrest 46 relative to the seat housing 25. The user can apply force to the bracket 48 to resist the biasing of the tooth 47 and selectively disengage the tooth 47 from the opening 49, thereby allowing movement of the headrest between multiple positions.

[0170] exist Figures 29A to 29B In another embodiment shown, the headrest 46 is again configured to engage with one of a plurality of openings 49 formed in, for example, an adjacent channel 51 mounted to the seat housing 25. However, as shown, instead of being coupled to the bracket 48, the track 61 is coupled to the headrest 46 and is movable therewith relative to the one or more channels 51. As shown, the headrest 46 itself may include protrusions or hooks 63 that cooperate with a portion of the headrest track 61 to engage the headrest track 61 to the headrest 46. As shown, the headrest track 61 can be retrained between the surface of the headrest 46 and the hooks 63.

[0171] Now see Figures 39A to 44 An example of a child restraint system 20 is shown, which 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 linking member 406a, 406b aligned with a plurality of openings or slots 404 disposed in the backrest 408 of the seat housing 25. Figure 40A and 40B In one embodiment, the opening or slot 404 is in the channel 402 located in the seat housing 25 of the child seat 24 (see...). Figure 39B As shown, the actuation mechanism 400 includes a first linking member 406a that can be positioned near a first side 412 of the rear portion 410 of the headrest 46 and a second linking member 406b disposed near a second opposite side 414 of the rear portion 410 of the headrest 46. However, embodiments including only a single linking member or alternatively including more than two linking members are within the scope of this invention.

[0172] 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 located at or near the top 418 of the headrest 46. The actuator 416 may be located at the front of the headrest ( Figure 39B ) or via the back of the headrest 46 (see Figure 46The at least one linking component 406a, 406b is operatively coupled to the at least one actuator 416. As shown, the first end of each of the plurality of linking components 406a, 406b is connected to the actuator, or in some embodiments is integrally formed with the actuator.

[0173] Corresponding locking mechanisms 420a, 420b may be associated with each linking member 406a, 406b to selectively engage one or more of the plurality of openings 404 adjacent to the channel 402. Thus, in the non-limiting embodiment shown, the first locking mechanism 420a is operatively connected to the first linking member 406a, and the second locking mechanism 420b may be operatively connected to the second linking member 406b.

[0174] Examples of corresponding locking mechanisms 420a and 420b are shown in Figures 41A to 43B As shown in the figure, each locking mechanism 420a, 420b may include a first locking member 422 operably coupled to a second locking member 424. In the illustrated non-limiting embodiment, the second locking member 424 may be arranged at or integrally formed with the distal ends of the linking members 406a, 406b. The first locking member 422 is movably coupled to the second locking member 424 and includes a feature 426 configured to engage a corresponding opening 404 of the channel 402. For example, a biasing mechanism 428 such as a spring may be configured to bias the first locking member 422 to engage one of a plurality of openings or slots 404 formed in the adjacent channel 402 mounted to the seat housing 25. This engagement between the first locking member 422 and the corresponding slot 404 restricts movement of the headrest 46 relative to the seat housing 25.

[0175] The first locking component 422 can disengage from the corresponding opening 404 in response to the application of a 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, a force F is applied to the at least one linking component 406 operably connected to the handle, causing the at least one linking component 406 to change from a locked position to an unlocked position. This movement of the at least one linking component 406a, 406b relative to the headrest 46 to the unlocked position resists the biasing force of the biasing mechanism 428.

[0176] In one embodiment, for example, by applying force to actuator 416, movement of the second locking member 424 to the unlocked position will simultaneously cause the first locking member 422 to change from the locked position (41A, 42A, 43A) to the unlocked position (41B, 42B, 43B). Therefore, the connection between the first locking member 422 and the second locking member 424 results in the first locking member 422 being in the same configuration (locked or unlocked) as the second locking member 424. For example, when the first locking member 422 is in the locked configuration, the second locking member 424 is also in the locked configuration, and when the first locking member 422 is in the unlocked configuration, the second locking member 424 is also in the unlocked configuration.

[0177] An example of the interface between the first locking component 422 and the second locking component 424 is shown in Figures 41A to 41B As shown in the diagram. In the illustrated non-limiting embodiment, the second locking member 424 has a groove or recess 430 formed therein, for example, near the end 432 of the second locking member 424. The first locking member 422 may include a locking feature 434, such as a protrusion. The first locking member 422 may be pivotally mounted to the structure of the headrest 46 such that the locking feature 434 is arranged within the recess 430 formed in the second locking member 424. As the second locking member 424 moves vertically upward in response to the application of a force to the actuator 416, the engagement between the locking feature 434 and the recess 430 will cause the first locking member 422 to pivot about its axis and disengage from engagement with the slot 404. Similarly, when the actuator 416 is released, the biasing force of the biasing mechanism 428 will exert a downward force on the second locking member 424, and the engagement between the locking feature 434 and the recess 430 will cause the first locking member 422 to pivot about its axis and engage with the adjacent slot 404.

[0178] However, in other embodiments, for example Figures 42A to 42B As shown, the first locking member 424 can be pivotally mounted to the structure of the headrest 46 and pivotally directly coupled to the second locking member 424. In this embodiment, upward movement of the second locking member 424 toward the unlocked position causes the first locking member 422 to pivot about two axes and disengage from the slot 404. Furthermore, downward movement of the second locking member 424 toward the locked position, driven downward by the biasing mechanism 428, causes the first locking member 422 to pivot about two axes and engage with the adjacent slot 404.

[0179] Another example of a locking mechanism, such as locking mechanism 420a or 420b, is... Figures 43A to 43BAs shown in the figure, the second locking member 424 may have a slot 436 formed therein, and the first locking member 422 is slidably coupled to the second locking member 424 via the slot 436. When the second locking member 424 moves upward, the first locking member 422 is configured to translate relative to the second locking member 424 via the slot 436. Because the slot 436 is arranged at an angle relative to the backrest 408, when the second locking member 424 moves upward, the first locking member 422 translates and disengages from the slot 404. When the second locking member 424 moves downward, for example in response to the biasing force of the biasing mechanism 428, the first locking member 422 translates laterally to engage 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 locking mechanisms with other configurations, such as where the first locking member 422 is configured to pivot and translate between a locked position and an unlocked position, are within the scope of this invention.

[0180] refer to Figure 24 One or more shock absorbers or side impact chambers 250, designed to absorb forces in the event of an accident or collision, may be arranged on the exterior of the backrest portion 28 of the seat housing 25. While the side impact chambers are shown arranged near the top 32 of the backrest portion 28, it should be understood that they can be positioned at any suitable location. In the non-limiting embodiment shown, a first side impact chamber 250 wraps from the back surface 53 of the backrest portion 28 to the outer surface of a first upright side member 36, and a second substantially identical impact chamber 250 wraps from the back surface 53 around the outer surface of a second upright side member 40. However, it should be understood 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 see Figure 24 The recess 55 may be formed in the seat housing 25, for example, in the backrest portion 28 of the seat housing 25. In the non-limiting embodiment shown, the recess 55 is formed in the back surface 53 and is sized to receive manual commands associated with the child restraint system 20.

[0181] As best shown in Figure 23, the seat portion 26 includes a seat support surface 50, which generally faces 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 member 56 may be disposed at a first side 58 of the seat support surface 50, and a second seat side member 60 may be disposed 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 upward and from the left and right sides of the seat portion. The seat support surface 50 and the first seat side member 56 and the second seat side member 60 define an area 64 in combination, within which at least a portion of a child's lower body can be accommodated.

[0182] As shown in the figure, the first seat side member 56 and the second seat side member 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 be the same as the angle of the first upright side member 36 relative to the upright support surface 30, but it is not necessary. Similarly, the angle of the second seat side member 60 relative to the seat support surface 50 may be the same as the angle of the second upright side member 40 relative to the upright support surface 30, but it is not necessary. In an embodiment, the first upright side member 36 and the first seat side member 56 are integrally formed, and the second upright side member 40 and the second seat side member 60 are integrally formed.

[0183] Although not generally shown, the child seat 24 also includes a protective harness assembly for restraining a child within the child seat 24. A typical protective harness assembly includes two shoulder straps that can be connected via buckles to at least one crotch strap. (Reference) Figure 26 In one embodiment, the opening 69 formed in the seat portion 26 of the child seat 24 and associated with the crotch strap of the protective belt assembly may have a generally H-shape. By configuring the opening 69 in this manner, the crotch buckle can be easily adjusted between a frontal and rearward position relative to the seat support surface 50.

[0184] 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 manufacturing the base body include, but are not limited to, rigid plastics or composite materials. The base seat portion 72 and the base rear portion 74 can be integrally formed as a single body, or alternatively, can be formed by separate components that are removable or permanently connected together. (Reference) Figure 5 In the illustrated non-limiting embodiment, the support base 22 includes a first base member 76 having a bottom surface 78 suitable for placement on a support surface such as a vehicle seat 10, and a second base member 80 coupled to the first base member 76. In the illustrated non-limiting embodiment, at least a portion of the second base member 80 is positioned to overlap with the upper surface 82 of the first base member 76. In the embodiment shown in the figures, the rear base portion 74 of the support base 22 is formed solely by the second base member 80, and the base seat portion 72 of the support base 22 is formed by a combination of the first base member 76 and the second base member 80.

[0185] refer to Figures 47A to 47BStorage compartment 500 may be formed in a portion of support base 22. While storage compartment 500 is shown as being formed only in the second base member 80, embodiments in which storage compartment 500 is formed only in the first base member 76, or alternatively formed by a combination of the first base member 76 and the second base member 80, are also within the scope of this invention. In one embodiment, one or more latches 502 of a latching system for attaching a child seat system 20 to a vehicle seat, for example, may be held within storage compartment 500. As shown, cover 504 may be in an open position relative to support base 22 (…). Figure 47A ) and closing position ( Figure 47B The cover 504 can be moved between the support base 22 to selectively seal the storage compartment 500. In one embodiment, the cover 504 can be removed from the support base 22. However, in other embodiments, the cover 504 can be movably coupled, for example, pivotally or hingedly coupled to the support base 22, such that the cover 504 remains attached to the support base when it is in the open or closed position.

[0186] As shown in the figure, the child seat 24 can be directly attached to the second base component 80. For example, the base seat portion 72 of the second base component 80 may include a contour or opening 84 (see Figure 80). Figure 7 The bottom end 86 of the child seat 24 is disposed within the opening 84. In one embodiment, as... Figure 6A and 6B As shown, for example, the bottom end 86 of a child seat 24, disposed below the seat portion 26 of a child seat, includes a flange 88 having an edge formed by rolling or otherwise shaping to form an edge or seat anchor 90. A second base component 80 may include one or more hooks or anchors 92 having a corresponding curvature configured to engage the edge 90. In one embodiment, as... Figure 27A As best shown, the flange 88 forming the edge 90 is a ring removably coupled to the bottom of the child seat 24 via at least one fastener and, in some embodiments, by a plurality of fasteners 91. Although eight screws are shown, it should be understood that any suitable fastener or coupling is within the scope of this invention. Furthermore, any number of fasteners or couplings, including single, two, three, four, five, six, seven, or more than eight fasteners, are covered herein. Alternatively or additionally, one or more pins 93 (see [reference]) are embedded within the child seat 24. Figure 27B It can be used to attach flange 88 to child seat 24.

[0187] The child seat 24 can rotate relative to the support base 22 between multiple configurations. In one embodiment, the child seat 24 can rotate relative to both a first base member 76 and a second base member 80 of the support base 22. For example, engagement between the seat anchor 90 and a corresponding hook 92 formed on the second base member 80 can define the rotation path of the child seat 24 relative to the support base 22. As shown, the child seat 24 can rotate between a first rotation configuration and a second rotation configuration, the first rotation configuration being, for example, in a forward-facing position (…). Figure 2 The second rotating configuration, for example, wherein the child seat 24 is in a rear-facing position ( Figure 3 The child seat 24 may be positioned in one or more additional configurations between the first and second swivel configurations. However, it should be understood that embodiments in which the child seat 24 may be positioned between the first and second swivel configurations are also within the scope of this invention.

[0188] At least one base anchoring member 94 may be fixedly connected to the rear portion 74 of the base of the supporting base 22. In the non-limiting embodiment shown, the base anchoring member 94 is attached to and protrudes from the second base member 80 near its distal end 96. The base anchoring member 94 may be connected to a corresponding seat anchoring member 98 of the child seat 24. This seat anchoring member 98 is typically arranged on the surface of the backrest portion 28 of the child seat 24 (e.g., behind the child's back), and thus the base anchoring member 94 can be connected to the seat anchoring member when the child seat 24 is in a face-up configuration. As will be described in more detail below, the base anchoring member 94 may also be connected to the seat anchoring member 98 regardless of the tilt angle of the child seat 24 relative to the supporting base 22. This connection between the base anchoring member 94 and the seat anchoring member 98 stabilizes the backrest portion 28 of the child seat 24. In such embodiments, the base anchoring member 94 may not be able to be connected to the seat anchoring member 98 when the child seat 24 is in a rear-facing configuration. However, it should be understood that the base anchoring component 94 can be used with seat anchoring components located anywhere around the child seat 24.

[0189] The child restraint system 20 may include a spinlock 100 operable to selectively lock the child seat 24 in one of the plurality of configurations relative to the support base 22. In the illustrated non-limiting embodiment, the spinlock 100 is disposed within the seat housing 25 of the child seat 24, for example, within a portion of the end 86 within the support base 22. Reference Figures 9 to 10BIn the non-limiting embodiment shown, the spinlock 100 includes a centrally positioned link 102 rotatable about an axis X. As shown, the link 102 may have two end segments 104 extending outwardly therefrom, for example, positioned 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 may extend from the link 102 in opposite directions.

[0190] Locking pin 106 can be in a first locked position in which the child seat 24 cannot rotate relative to the support base 22. Figure 10A ) and the second unlocked position in which the child seat 24 can rotate freely relative to the support base 22 ( Figure 10B The lock pins 106, and therefore the spinlock 100, are in the locked position. When each of the locking pins 106, and therefore the spinlock 100, is in the locked position, the second opposing end 110 of the locking pin 106 extends through an opening (not shown) formed in the seat housing 25, and engages with the corresponding locking section 112 (see [link to lock section]). Figure 7 The locking pin 106, and therefore the spinlock 100, is engaged, for example, by a groove or slot formed in a portion of the support base. When the locking pin 106, and therefore the spinlock 100, is in the second unlocked position, the second end 110 of the locking pin 106 separates from the locking section 112, thereby allowing the child seat 24 to rotate relative to the second base member 80. In the non-limiting embodiment shown, the plurality of locking sections 112 are formed in the second base member 80. However, embodiments in which the plurality of locking sections 112 are formed in the first base member 76 are also covered herein.

[0191] In one embodiment, a biasing component (not shown), such as a torsion spring, is operably coupled to link 102 to bias link 102 and thus 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 illustrated non-limiting embodiment, a plurality of actuators 114 are operably coupled to spinlock 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 operated independently or individually to change the locking pin 106 from the locked position to the unlocked position. Alternatively or additionally, the first actuator 114a and the second actuator 114b can be operated simultaneously to change the locking pin 106 from the locked position to the unlocked position.

[0192] In the illustrated non-limiting embodiment, the one or more actuators 114a, 114b are substantially identical and include a handle 116 disposed on the outer surface of the child seat 24. The handle 116 may be directly or indirectly connected to the locking pin 106. To operate the actuators 114a, 114b to move the locking pin 106 to the unlocked position, the user applies 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 inward or pivoted, are also within the scope of this 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 to which it is connected. The inward movement or translation of the first locking pin 106 causes the linkage 102 to rotate about its axis X in a first direction, thereby resisting the biasing of the biasing member. Because the second locking pin 106 is also connected to the link 102, rotation of the link 102 via the first locking pin 106 causes a similar inward movement of the second locking pin 106. This inward movement causes the second ends 110 of both locking pins 106 to disengage from the corresponding locking sections 112 of the support base 22. With the actuator 114a activated and the locking pins 106 disengaged from the locking sections 112, the user can then rotate the child seat 24 relative to the support base 22 to the desired rotation configuration.

[0193] Once the child seat 24 has reached the desired rotational configuration, the user will release actuators 114a, 114b. After releasing actuators 114a, 114b, the biasing force of the biasing component will cause the link 102 to rotate and the locking pin 106 to translate outward through the opening formed in the seat housing 25 and engage with the corresponding locking section 112 associated with the rotational configuration of the child seat 24.

[0194] For reference Figures 11 to 12B Another example of a spinlock 100 is shown. In the illustrated non-limiting embodiment, the spinlock 100 includes a plurality of locking components, such as a first locking component 120 pivotally mounted near a first side of the seat housing 25, and a second substantially identical locking component 120 pivotally mounted near a second opposite side of the seat housing 25. Each locking component 120 has a first connector 122 and a second connector 124 extending in different directions from a side 126 inward from a first face of the locking component 120. A first connecting band 128 extends between and connects the first connector 122 of the first locking component 120 and the second connector 124 of the second locking component 120. Similarly, a second connecting band 128 extends between and connects the second connector 124 of the first locking component 120 and the first connector 122 of the second locking component 120.

[0195] Locking component 120 can be in a first locked position in which the child seat 24 cannot rotate relative to the support base 22. Figure 12A) and the second unlocked position in which the child seat 24 can rotate freely relative to the support base 22 ( Figure 12B The child seat 24 can be rotated between the two positions. When each of the locking components 120 is in the locked position, a locking pin 130 protruding from its second or outward-facing surface 131 extends through an opening (not shown) formed in the seat housing 25 and engages with a corresponding locking section 112, such as a groove 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 section 112 may, but does not need to, be formed in the second base component 80. When the locking component 120 is in the second unlocked position, the locking pin 130 disengages from the locking section 112, thereby allowing the child seat 24 to rotate.

[0196] A biasing component, such as a torsion spring, is operably coupled to at least one or each of the locking components 120 to bias each locking component 120 about its axis to a locked position. Similar to previous embodiments, actuators 114a, 114b, such as handle 116, are operably coupled to each locking component 120. A first actuator 114a may be operably coupled to a first locking component 120, and a second actuator 114b may be operably coupled to a second locking component 120. Furthermore, each actuator 114a, 114b may be independently operable, or alternatively or additionally, actuators 114a, 114b may operate uniformly to change the locking pin 130 from a locked position to an unlocked position.

[0197] To unlock the child seat 24, the user applies force, for example, an outward force, to the handle 116 of the actuators 114a, 114b. However, it should be understood that the spinlock 100 can be adapted to another type of movement of the actuator 114. The first locking member 120 is configured to rotate about its axis in response to operation of the first actuator 114a. This rotation causes the locking pin 130 to rotate inward away from the locking section 112, and the opposite portion of the locking member 120 to rotate outward. A similar rotational force is applied to the second locking member 120 via the connection between the first and second locking members 120 through the plurality of link straps 128. In the non-limiting embodiment shown, the first connector 122 is located near the first end 132 of the locking member 120, and the second connector 124 is located near the second end 134 of the locking member 120 and the locking pin 130. Thus, when the actuator 114a is operated, the first connector 122 rotates outward, thereby applying a force to the second connector 124 of the second locking member 120 via the first link strap 128. The force acting on the second connector 124 of the second locking member 120 causes the second locking member 120 to pivot about its axis, thereby disengaging the locking pin 130 from the corresponding locking section 112. With the actuator 114a activated and the locking pin 130 disengaged from the locking section 112, the user can then rotate the child seat 24 relative to the support base to the desired rotation configuration.

[0198] Once the child seat 24 has reached the desired rotational configuration, the user releases actuator 114a. Upon release of actuator 114a, the biasing force of the biasing member causes the first locking member 120 to pivot about its axis to a locked position. In response to this rotation, the second connector 124 of the first locking member 120 transmits force to the first connector 122 of the second locking member 120. This force pulls inwardly at the first end 132 of the second locking member 120, causing the locking pin 130 of the second locking member 120 to rotate outward and engage with the adjacent locking section 112 associated with the said position of the child seat 24. It should be understood that the various configurations of the spinlock 100 shown and described herein are intended only as examples, and any mechanism suitable for selectively locking and unlocking the child seat 24 relative to the support base 22 about its axis is within the scope of this invention.

[0199] For reference Figures 13 to 15 An alternative embodiment of the spinlock 100 is shown. In a non-limiting embodiment, the spinlock 100 is substantially the same as that described above. Figures 9 to 10B The spinlock shown and described; however, unlike Figures 9 to 10B In the embodiment shown, 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 understood that embodiments in which these axes are offset from each other, for example in… Figures 9 to 10B As shown in the figure, it is also within the scope of this utility model.

[0200] Another example of the spinlock 300 is... Figures 48 to 51 As shown in the figure. Similar to the previous embodiment, the spinlock 300 is disposed within the seat housing 25 of the child seat 24, for example, within the portion of the end 86 that can be housed within the support base 22. As shown, the spinlock 300 includes a centrally positioned link 302 that can rotate or pivot about an axis X. The link 302 can be attached to the support base 22 via any suitable connecting mechanism, such as a pin or bolt, that allows the link 302 to rotate freely about its axis. As shown, the link 302 may have two end segments 304 extending outward therefrom, for example, positioned on opposite sides of the link 302 relative to the axis of rotation. At least one locking pin, such as two locking pins 306, is connected to the link 302. For example, a first end 308 of each locking pin 306 is connected to a corresponding end segment 304 of the link 302. As shown, the locking pins 306 may extend from the link 302 in opposite directions. Although the spinlock 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 locking component 306 is operably coupled to the link 302 are also within the scope of this invention.

[0201] Similar to the previously described embodiments, the locking pin 306 can be in a first locked position in which the child seat 24 cannot rotate relative to the support base 22. Figure 49A ) and the second unlocked position in which the child seat 24 can rotate freely relative to the support base 22 ( Figure 49B The lock pins 306 and thus the spinlock 300 are in the locked position. When each of the locking pins 306, and therefore the spinlock 300, is in the locked position, the second opposing end 310 of the locking pin 306, for example, a boss disposed at the second end of the locking pin 306, extends through an opening (not shown) formed in the seat housing 25 and engages with a corresponding locking opening 312 (see [link to lock opening]). Figure 51 The locking pin 306, and therefore the spinlock 300, is engaged, for example, in a groove or slot formed in a portion of the support base. When the locking pin 306, and therefore the spinlock 300, is in the second unlocked position, the second end or boss 310 of the locking pin 306 separates from the locking 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 locking openings 312 are formed in the second base member 80. However, embodiments in which the plurality of locking openings 312 are formed in the first base member 76 are also covered herein. Although not illustrated, a biasing component (not shown), such as a torsion spring, may be operatively coupled to the link 302 to bias the link 302, and therefore the locking pin 306, to the first locked position.

[0202] Actuator 314 is associated with at least one of locking pins 306. Figures 48 to 51 In the illustrated non-limiting embodiment, the spinlock 300 includes a corresponding actuator 314 operably coupled to each of the locking pins 306. As shown, the actuator 314 may be integrally formed with the locking member 306, such that the actuator 314 and the locking pin 306 are a single entity. The actuator 314 may be arranged near the second end 310 of the locking pin 306 and may 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 located at another position relative to the locking pin 306, such as on one side of the locking pin 306, are also covered herein. The outward-facing surface 316 of the actuator 314 may be vertically aligned with the second end 310 of the locking pin 306. In other embodiments, the outward-facing surface 316 may be spaced further away from the axis of the link 302 than the second end 310. Actuator 314 is disposed within an opening 320 formed in the seat base 26 and extends through the opening in some embodiments. Actuator and locking pin 306 can move in the same direction, such as the actuation direction, to selectively disengage boss 310 from the corresponding locking opening 312.

[0203] When a force is applied to actuator 314, for example, in a direction toward the interior of child seat 24, actuator 314 and locking pin 306 translate laterally toward the axis. This translation causes the boss 310 of locking pin 306 to disengage from the corresponding locking opening 312 formed in support base 22, and causes connecting member 302 to rotate about its axis. Because locking members 306 are symmetrically attached to connecting member 302, actuation of one locking pin 306 results in tandem movement of the plurality of locking members 306. Once locking pin 306 is disengaged from support base 22, the user can spin or rotate child seat 24 relative to support base 22. Once child seat 24 is in the desired rotational position, the force applied to actuator 314 is released. In response to the removal of the force, a biasing mechanism (not shown) operably coupled to connecting member 302 biases connecting member 302 about its axis and biases locking pin 306 into an engaged position to relock child seat 24 to support base 22. When the actuator 314 of the spin lock 300 is not pressed, the biasing force of the biasing mechanism prevents the child seat 24 from rotating.

[0204] However, it should be understood that embodiments in which the actuator 314 is arranged in another location around the child seat 24, such as near the front of the child seat 24, are also within the scope of this invention. In such embodiments, the actuator may be directly or indirectly coupled to the locking pin 306. In embodiments in which the actuator 314 is arranged near the front of the child seat, such as near the passenger's feet, the position of the actuator 314 and / or the biasing force of the biasing mechanism associated with the connecting member 302 are sufficient to prevent accidental unlocking of the spinlock 300 if the passenger kicks the actuator 314.

[0205] refer to Figures 15 to 17B In one embodiment, the spinlock 100 may additionally provide the operator of the child restraint system 20 with a visual indicator 200 to indicate whether a locking component, such as component 106 or 120, engages with the support base 22 to lock the child seat 24 to prevent rotation relative to the support base 22, or whether locking components 106, 120 disengage from the support base 22, thereby allowing the child seat 24 to rotate. The visual indicator 200 is associated with the spinlock 100. In one embodiment, the visual indicator 200 is operatively coupled to a portion of the spinlock 100, such as locking component 106, and is arranged generally aligned with a window 202 formed in a portion of the support base 22. A portion of locking component 106 may be configured to contact and apply force to the visual indicator 200, for example, when the locking 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 or integrally formed with a portion of locking component 106 are also within the scope of this invention.

[0206] In the non-limiting embodiment shown, indicator 200 includes a first indicator segment 204, for example, having a first color, 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, operable to indicate that the child seat 24 is freely rotatable relative to the support base 22. Alternatively or additionally, indicator 200 may include alphanumeric characters, such as the words for locked or unlocked, or some other symbol, to represent one or both of these conditions respectively.

[0207] As shown, the indicator 200 can be movably mounted to a scraper 208 aligned with the locking member 106. In the non-limiting embodiment shown, the scraper 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 scraper 208, and the biasing force of the biasing member 212 can bias the indicator 200 to a second position, wherein the second indicator segment 206 is aligned with the window 202. Figure 16A As best shown in the figure, when the locking member 106 is in the locked position, a portion of the locking member 106 is operable to engage at least one of the scraper 208 and the indicator 200. The force applied by the locking member 106 to the scraper 208 or the indicator 200 resists the biasing force of the biasing member 212, thereby holding the indicator 200 in a position in which the first indicator section 204 is aligned with the window 202.

[0208] When the user applies force to the handle 116 of the actuator 114 to release the spinlock 100, the locking member 106 moves, for example, translates, and disengages from the indicator 200 and / or the scraper 208. Therefore, the biasing force of the biasing member 212 will bias the scraper 208 and the indicator 200 to a position where the second indicator section 206 of the indicator 200 is aligned with the window 202. Figure 16B Once the force is released from the handle 116, the biasing component associated with the spinlock 100 will bias the locking component 106 toward the locked position and engage with the indicator 200 and / or the scraper 208 as previously described.

[0209] For reference Figures 17A to 17B The figure 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, a plunger 220 extends through the window 202. Figure 17AThe plunger 220 may be part of the locking member 106 or a separate component movably coupled thereto. The portion of the plunger 220 visible at window 202 may have a first color or alphanumeric markings or symbols 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 window 202. When the handle 116 of actuator 114 is actuated and the locking member 106 of the spinlock 100 is in the unlocked position, the plunger 220 may move, for example, retract, and thus not be present within window 202. In fact, as... Figure 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 can rotate freely.

[0210] refer to Figure 28 In one embodiment, for example, the handle 116 of the actuator 114 associated with the spinlock 100 includes a secondary lock 136 operably coupled thereto. In the illustrated non-limiting embodiment, the secondary lock 136 includes a component 138 movable to selectively disengage the support base 22. For example, the component 138 may include a protrusion 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 its unintentional actuation and thus to prevent the spinlock 100 from releasing. In such embodiments, the user must first unlock the secondary lock 136, for example, by sliding the component 138 away from or disengaging from the support base 22, and then operate the actuator 114 by applying 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.

[0211] Referring now to Figures 18 to 21B, the child seat 24 can alternatively or additionally move relative to the support base 22 to adjust the tilt of the child seat 24. The child seat 24 can be positioned, for example, in an upright position ( Figure 21A The first position and, for example, the leaning position () Figure 21B The child seat 24 moves along a tilted path between two positions. However, it should be understood that both the first and second positions can be tilted arrangements with different degrees of tilt. Furthermore, embodiments in which the child seat 24 can be arranged in any of a plurality of positions between an upright position and a reclined position are also covered herein (see, for example, those discussed below). Figure 31A To C).

[0212] In one embodiment, the second base member 80 and the child seat 24 coupled thereto are translatable relative to the first base member 76 to control the tilt or recline of the child seat 24. As shown, a recline locking mechanism 140 may be mounted to the second base member 80. In the illustrated non-limiting embodiment, the recline locking mechanism 140 includes a centrally positioned pivot link 142 rotatable about an axis. As shown, the pivot link 142 may have two end segments 144 extending outward therefrom, for example, positioned on opposite sides of the pivot link 142 relative to its axis of rotation. At least one tilt pin, such as two tilt pins 146, is connected to the pivot link 142 via a corresponding connector 148. In the illustrated non-limiting embodiment, the connector 148 is pivotally coupled to the pivot link 142 and is translatable relative to the tilt pin 146. For example, the tilt pin 146 may have an elongated slot 150 formed therein, and the connector 148 may have a pin or post 152 disposed within the slot 150. As shown, connector 148 and rear tilt pin 146 can extend from pivot link 142 in opposite directions.

[0213] The plurality of rear-end pins 146 can be uniformly positioned in a first locked position in which the second base component 80 is immobile relative to the first base component 76. Figure 21A The child seat 24, which is rotatably connected to the second base component 80, can move freely relative to the first base component 76 to adjust the second unlocked position of the tilt of the second base component 80 and the child seat 24. Figure 21B The tilt pins 146 can be switched between the two positions. When each of the tilt pins 146 is in the locked position, the second end 154 of the tilt pin 146 extends through an opening formed in the second base member 80 and engages with a corresponding locking opening 156 formed in a portion of the first base member 76 (e.g., its sidewall). When the tilt pin 146 is in the second unlocked position, the second end 154 of the tilt pin 146 separates or disengages from the locking opening 156, thereby allowing the second base member 80 and the child seat 24 to tilt or recline.

[0214] In one embodiment, a biasing component 157, such as a coil spring, is operably coupled to each of the tilt pin 146 and the connector 148, and is operable to bias the tilt pin 146 to a first locked position via movement of the connector 148. In other embodiments, the biasing component may be operably coupled to the pivot link 142. An actuator 160 is operably coupled to the tilt lock mechanism 140. In the non-limiting embodiment shown, the pivot link 142 includes a radially extending actuating tab 158, and the actuator 160 includes a handle 162 disposed on the outer surface of the support base 22. The handle 162 is coupled to the actuating tab 158 via a linkage mechanism or 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 a force to the tilt pin 146, thereby causing the pin 152 of the connector 148 to translate within a slot 150 formed in the tilt pin 146. In response to this movement of pin 152, a force is applied to the biasing member 157 to resist its bias. Movement of connector 148 will cause a corresponding movement of tilt pin 146 from the locked position to the unlocked position. While tilt pin 146 is held in the unlocked position by the application of force to handle 162, the second base member 80 can translate relative to the first base member 76. Figure 20 As best shown herein, the first base component 76 includes a plurality of locking openings 156, each locking opening associated with a different tilt of the child seat 24. The second base component 80 is thus movable to a position in which the end 154 of the tilt pin 146 is aligned with and configured to engage with a corresponding locking opening among the plurality of locking openings 156. It should be understood that the tilt locking 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 the movement of the second base component 80 relative to the first base component 76 to adjust the tilt of the child seat 24 is within the scope of this invention.

[0215] refer to Figures 30A to 31CA recline indicator 166 may be provided to indicate the current recline position of the child seat 24. In the illustrated non-limiting embodiment, the recline indicator 166 includes a plurality of first marks 167 and second marks 168. Each of the plurality of first marks 167 may be selectively positioned relative to the second marks 168 to indicate a corresponding recline position of the child seat 24. The plurality of first marks 167 are spaced apart from each other such that each first mark 167 may be aligned with the second mark 168 in a particular recline position due to translational movement of the second base member 80 relative to the first base member 76. It will be understood that four discrete recline positions are shown, but various other numbers of discrete positions may be provided. In some embodiments, a continuous range of positions may be indicated. As shown, the base seat portion 72 of the supporting base 22 includes the plurality of first marks 167, and the first base member 76 includes the second marks 168. However, it should be understood that embodiments in which a single first mark 167 is arranged 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 this invention.

[0216] For reference Figure 7 , 8A In one embodiment, the support base 22 includes a seatbelt tensioner 170. In the illustrated non-limiting embodiment, an opening 172 is formed in the rear base portion 74 of the support base 22, and the seatbelt tensioner 170 is receptacle within the opening 172. The profile of the seatbelt tensioner 170 may be complementary to the profile of the opening 172, such that the substantially integral portion of the seatbelt tensioner 170 is receptacle within the opening 172. A vehicle seatbelt 12 (see [reference]) is associated with a vehicle seat 10 on which the support base 22 may be positioned. Figure 22B The seatbelt tensioner 170 can be positioned along a seatbelt retraction path defined between a surface 174 of the rear portion 74 of the base of the support base 22 and the seatbelt tensioner 170. In one embodiment, the seatbelt tensioner 170 includes a frame 171 having an actuator 173 mounted to the frame 171. The actuator 173 may be operable to selectively release or disengage a corresponding engaging member of the frame 171 from a strip or other connector 175 arranged within an opening 172. Figure 8A and 8B In the non-limiting embodiment shown, the front surface or face of actuator 173 has a generally circular profile.

[0217] In one embodiment, the seatbelt tensioner 170 can be selectively movable relative to the support base 22 to adjust the tension applied to the vehicle seatbelt 12 along the vehicle seatbelt storage path. For example, the seatbelt tensioner 170 can be configured in the open position ( Figure 7 , 22Aand 22B) and the closed position ( Figure 2 and 3 The support base 22 pivots about at least one axis between the seat belt tensioner 170 and the opening 172 to selectively pinch or tighten the portion of the vehicle seat belt 12 that is clamped between the seat belt tensioner 170 and the opening 172 to connect the support base 22 to the vehicle seat belt 12, thereby restricting the movement of the support base 22 relative to the vehicle seat 10.

[0218] For reference Figures 35 to 36B In some embodiments, the vehicle seatbelt 12 may be pressed against or pressed between various features of the seatbelt tensioner 170 and / or the rear portion 74 of the base of the support base 22 to provide additional tension and / or friction, thereby preventing the vehicle seatbelt 12 from slipping relative to the support base 22. In one embodiment, as Figure 36A As shown in Figure B, the seatbelt tensioner 170 may include one or more tensioner ribs 171a to 171d projecting from the seatbelt tensioner 170 toward and into the opening 172. In embodiments including multiple tensioner ribs 171a to 171d, the ribs may extend from the surface of the seatbelt tensioner 170 by different axial lengths. The rear portion 74 of the base may be provided with one or more features at or within the opening 172. In the non-limiting embodiment shown, the at least one feature includes multiple rear ribs 173a to e. The rear ribs 173a to e may include corner ribs 173b, 173d and / or center rib 173c. The surface 174 of the rear portion 74 of the base may additionally or alternatively be provided with 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 seatbelt tensioner 170 is closed and retracted into the opening 172, as Figure 36A As shown, the vehicle seat belt 12 is forced to change direction along a meandering or zigzag path defined between tensioner ribs 171a to 171d, a first corner 174a and a second corner 174b, and one or more central rear ribs 173a to 173e. Furthermore, the vehicle seat belt 12 is clamped or tensioned at multiple locations along said meandering path.

[0219] In one embodiment, such as Figure 22BAs best shown, one or more seatbelt guides 176 may be positioned around the support base 22, for example, its rear portion 74. As illustrated, the seatbelt guide 176 may include a slot 178 for receiving a portion of the vehicle seatbelt 12 therein. Although substantially identical seatbelt guides 176 are shown arranged on opposite sides of the rear portion 74 of the base, it should be understood that embodiments with a single seatbelt guide are within the scope of this invention. Furthermore, in embodiments comprising multiple seatbelt guides 176, the seatbelt guides may have different configurations and / or may be arranged in different vertical and lateral positions relative to the support base 22 based on the vehicle seatbelt path. Figures 23A to 23B In the non-limiting embodiment shown, the seatbelt guide 176 can be mounted to the support base 22, for example, via the seatbelt path insert 177 to the surface of the rear portion 74 of the base. The seatbelt path insert 177 can be permanently or removably attached to the support base 22, and the seatbelt guide 176 can be permanently or removably attached to the seatbelt path insert 177. Including the seatbelt path insert 177 allows the seatbelt guide 176 to be located at a position laterally offset from the rear portion 74 of the base.

[0220] refer to Figure 37A In some embodiments, from C to C and 38A to C, a seatbelt guide 176 may be provided in a lower region of the support base 22, for example, near the interface between the rear portion 74 of the base and the seat portion 72 of the base. The seatbelt guide 176 may be arranged to receive the leg strap of the vehicle seatbelt 12. One or more corrugated regions 176A, 176B may be provided on the surface of the rear portion 74 of the base, such as corrugated region 176A on the side surface and corrugated region 176B on the side and bottom surfaces. The corrugated regions 176A, 176B are arranged to receive the vehicle seatbelt 12 and further guide the vehicle seatbelt around the support base 22. Figure 38A As shown in Figure C, a plurality of ribs 182 may be provided in this area of ​​the support base 22 to provide additional stiffness and strength when the vehicle seat belt 12 presses against the support base 22. In some embodiments, a bottom cover 184 may be provided, and the bottom cover may include a portion of the ribs 182 in a complementary arrangement to provide a rigid structure when assembled with the support base 22.

[0221] refer to Figure 24In one embodiment, a notch or cutout 180 is formed at the front edge 52 of the child seat 24. To use the seatbelt tensioner 170 to attach the support base 22 to the vehicle seat 10 via the vehicle seatbelt 12, the child seat 24 is rotated relative to the support base 22 to a rear-facing configuration. In the rear-facing configuration, the notch aligns with the seatbelt tensioner 170 and the corresponding opening 172, such that when the seatbelt tensioner is open or disengaged from the opening 172, the seatbelt tensioner 170 is positioned within the notch 180 formed in the child seat 24. Therefore, when the seatbelt tensioner 170 is positioned within the notch 180, the seatbelt tensioner 170 interferes with and restricts the rotation of the child seat 24 relative to the support base 22. The child seat 24 can only be changed from the rear-facing configuration to another configuration once the seatbelt tensioner 170 is closed or retracted into the opening 172.

[0222] In one embodiment, the tension applied to the vehicle seatbelt 12 by the seatbelt 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, when the vehicle seatbelt 12 is coupled to the support base 22 via the seatbelt tensioner 170, the child seat 24 can be in a reclined or at least partially reclined position. During installation of the support base 22 around the vehicle seat 10, after the seatbelt tensioner 170 has applied initial tension to the vehicle seatbelt 12, the tilt of the child seat 24 is then adjusted to increase the tension of the vehicle seatbelt 12. While the child seat 24 is in any suitable rotational configuration relative to the support base 22, the recline locking mechanism 140, which couples the second base member 80 to the first base member 76, can be unlocked and adjusted, for example, to increase the tilt of the child seat 24. The corresponding movement of the seatbelt tensioner 170 increases the tension on the vehicle seatbelt 12 as the second base member 80 and the child seat 24 translate relative to the first base member 76.

[0223] The first seat side member 56 and the second seat side member 60 may form armrests for a child sitting in the child seat 24. In some embodiments, a cup holder 230 may be located near one end of at least one of the first seat side member 56 and the second seat side member 60, for example, closest to the front portion 52 of the seat support surface. These cup holders 230 may be fixed, or in some embodiments, may be rotatable relative to the seat housing 25 while remaining attached thereto. The rotatable cup holder 230 may: 1) provide easy access to the cup holder 230 for a child sitting in the child seat 24, 2) be moved to a position to allow the child easier entry and exit from the seat 24, 3) be moved to a position to minimize any interference of the cup holder 230 with the seat 24 and the support base 22 during rotation of the seat 24, and 4) be moved to a position to minimize the overall size (e.g., encapsulation) of the child restraint system 20 for, for example, the packaging, shipping, and placement of the system 20.

[0224] refer to Figures 32A to 33 The cup holder 230 is rotatable and configured to maintain discrete positions to, for example, 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 together with a child seat 24. In one embodiment, the cup holder 230 includes, for example, a stop 234 disposed on its bottom surface, and the child seat 24 includes a plurality of recesses 236 in which the stop 234 can be received. The plurality of recesses 236 may be arranged to define a plurality of different positions of the cup holder 230 relative to the child seat 24. Engagement between the stop 234 and a corresponding recess 236 of the plurality of recesses can hold the cup holder 230 in said position. Resilience may be present in one or both of the materials of the stop 234 and the defining recesses 236, such that the stop 234 may disengage from the recesses 236 when sufficient force is applied. Once the stop 234 is separated from the recesses 236, the cup holder 230 rotates freely about its pivot axis. In some embodiments, the pivot component 232 can be removed from the child seat 24 to allow the cup holder 230 to be removed.

[0225] like Figure 33 As shown, the rotation of the cup holder 230 can be limited to a desired range. In the illustrated non-limiting embodiment, the cup holder 230 includes a tab 238 on the opposite side of the pivot member 232. The child seat 24 may include a recess defined by sidewalls 240A, 240B. The tab 238 and sidewalls 240A, 240B are sized to allow a desired range of rotation, but engagement between the tab 238 and one or more of the sidewalls 240A, 240B prevents any further rotation. Thus, the sidewalls 240A, 240B can act as rotation-limiting stops.

[0226] refer to Figures 34A to 34CIn some embodiments, the child seat 24 may include a seat base 190 having a bottom surface 191 in its bottom portion for supporting a child and providing a shape suitable for textiles. The child seat 24 may also include at least one seat cushion 192A, 192B. As shown, the seat cushions 192A, 192B extend upward from the bottom surface 191 of the seat base 190, approaching the top of the corresponding first seat side member 56 and second seat side member 60. In embodiments, the seat cushions 192A, 192B terminate below the first seat side member 56 and second seat side member 60 of the backrest portion 28 of the seat housing 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 base 190. Seat cushions 192A and 192B are shown to be integrally formed from the same material as the seat base 190; however, in other embodiments, seat cushions 192A and 192B may be portions separate from the seat base.

[0227] Seat cushions 192A and 192B are arranged within the first seat side member 56 and the second seat side member 60 to reduce the seating width of a portion of the child seat 24, thereby improving side impact protection performance when protecting a child passenger. The seat cushions 192A and 192B of the illustrated embodiment are sized and positioned to reduce the seating width in the general area of ​​one or more of the passenger's hips, legs, and lower back. This position substantially reduces or substantially eliminates lateral movement of the child's body during a side impact event. Other positions or combinations of positions for the seat cushions 192A and 192B are contemplated, including cushions on only one side of the seat base 190. Furthermore, one or both of the seat cushions 192A and 192B may be removable to accommodate children of different sizes. The child restraint system 20, as described herein, allows adjustment of the rotational configuration and tilt of the child seat 24 relative to the support base 22 and the vehicle seat 10. The seat cushions 192A and 192B may be formed of various materials, including foam or other materials used elsewhere in the child seat 24. In some embodiments, seat cushions 192A, 192B are structural components of child seat 24. Seat cushions 192A, 192B may be formed of generally or substantially rigid or semi-rigid materials (e.g., hard plastic or foam materials that can be used in seat shells or headrests), in contrast to the materials of conventional car seat inserts made of, for example, fabrics and soft deformable foams without any internal rigid structure.

[0228] For reference Figures 45A to 45CAs previously described, the child seat 24 includes: a rear portion 28 comprising 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 reinforcing members 600 may be arranged around the child seat 24, for example at the rear portion 28. In the non-limiting embodiment shown, the at least one reinforcing member 600 is arranged on the outer surface of at least one upright side member 36, 40. The reinforcing member 600 may extend toward the top 32 of the rear portion 28 from a position near an interface with adjacent seat side members 56, 60. Furthermore, the reinforcing member 600 may 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. Including this reinforcing member 600 at the rear portion 28 of the seat housing 25 can help manage textiles (not shown) attached to the child seat 24. Alternatively or additionally, the reinforcing component 600 may absorb or redistribute the forces applied to the sides of the child seat 24, thereby improving the crash performance of the child seat 24, including side impact performance.
