[0071] 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.

[0072] Please refer to the following: Figure 1A-2An example of a child seat system 20 is shown. In each of the non-limiting embodiments shown, the child seat system 20 includes a support base 22 that can be detachably secured to the vehicle seat 10, such as by a latch or anchoring mechanism, not shown in the figure. This latch or anchoring system, often used, is sometimes referred to as a "lower anchor and tether for children," for example, the LATCH system. Alternatively or additionally, the child seat system 20 can be detachably secured to the vehicle seat 10 by a vehicle strap associated with the vehicle seat 10.

[0073] The child seat system 20 further includes a child seat 24 associated with a support base 22. In embodiments, 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. Additionally, at least a portion of the support base 22 and the child seat 24 may be permanently connected or secured together, as will be described in detail below. As used herein, the term "permanently connected" means an embodiment in which the child seat 24 or a portion thereof cannot be detached from the support base 22 by a user.

[0074] The child seat 24 includes a backrest portion 26 and at least a portion of a seat plate portion 28 arranged at an angle relative to the backrest portion 26. The seat plate portion 28 may, but need not, be configured to be removably coupled to the backrest portion 26. In the non-limiting embodiment shown, the backrest portion 26 is formed by the seat housing 25 of the child seat 24 and includes a backrest having an upright support surface 30, which is generally facing forward and extends from a first end or top 32 of the backrest portion 26 to a second opposite end or bottom 34 of the backrest portion 26. 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 26, 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 substantially orthogonally to the upright support surface 30, or alternatively, may extend from it at another angle, such as greater than 90°. Thus, the upright support surface 30 and the first upright side member 36 and the second upright side member 40 define a backrest area or upright support cavity in which the upper body of a child is accommodated.

[0075] When the child seat 24 is installed in a vehicle, the upright side members 36, 40 can assist in the proper positioning of the vehicle strap in one or more operating modes. In some embodiments, each upright side member 36, 40 has an opening 44a, 44b formed therein. The openings 44a, 44b can be configured to receive the vehicle strap (not shown) to secure the child seat 24 to the forward-facing vehicle seat 10, or to secure the upper body of a child located within the upright support cavity.

[0076] In the illustrated non-limiting embodiment, the backrest portion 26 of the child seat 24 includes a headrest 46. The headrest 46 may be attached to or integral with the backrest portion 26, or may be removably coupled to the backrest portion. The headrest 46 may be fixed, or in some embodiments, may be configured to move relative to the upright support surface 30. For example, the headrest 46 may be configured to translate relative to the upright support surface 30 between a retracted position and an extended position, thereby allowing adjustment according to the size of the child positioned within the child seat 24. However, it should be understood that embodiments in which the backrest portion 26 does not include a headrest 46 are also covered herein.

[0077] The seat portion 28 of the child seat 24 may include a seat support surface 50, generally upward-facing, extending from a first end or front portion 52 of the seat portion 28 to a second end or rear portion 54. A first seat side member 56 may be disposed on a first side 58 of the seat support surface 50, and a second seat side member 60 may be disposed on 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, respectively. The seat support surface 50 and the first seat side member 56 and the second seat side member 60 together define an area in which at least a portion of a child's lower body can be accommodated.

[0078] As shown in the figure, seat side members 56 and 60 extend from seat support surface 50 at an angle. The angle of the first seat side member 56 relative to seat support surface 50 may, but does not need to, be the same as the angle of the first upright side member 36 relative to upright support surface 30. Similarly, the angle of the second seat side member 60 relative to seat support surface 50 may, but does not need to, be the same as the angle of the second upright side member 40 relative to upright support surface 30.

[0079] In the illustrated non-limiting embodiment, each seat side member 56, 60 has a groove 66 formed therein, which is configured to act as a leg strap guide during at least one usage mode of the child seat 24. In some operating modes of the child seat 24, the groove 66 may be configured to receive and position the leg strap portion of a vehicle restraint member or a separate restraint strap to secure the child within the child seat 24.

[0080] The seat portion 28 of the child seat 24 may be a seat support surface 70 that can be removably attached to the child seat system 20 (see...). Figure 2 In the illustrated non-limiting embodiment, the seat support surface 70 may be formed from a portion of the seat housing 25 located above the support base 22. However, in other embodiments, the seat support surface 70 may be the surface of the support base 22 itself, such that the seat portion 28 may be positioned directly adjacent to the support base 22. When separated from the remainder of the child seat system 20, the seat portion 28 may be configured as a booster seat, which may be positioned to directly contact the vehicle seat and configured to support a child thereon. Although not shown, the seat portion 28 may include one or more positioning features configured to cooperate with one or more corresponding positioning features disposed on or near the seat surface or the backrest portion 26, or extending from or near the seat surface or the backrest portion. These combined positioning and location features are operable to correctly position the seat portion 28 relative to the seat support surface 70 when the seat portion is installed.

[0081] The booster seat may include a booster locking mechanism 80 operable to selectively engage the booster seat with the remainder of the child seat system 20. The booster locking mechanism 80 includes at least one locking member 82 movably mounted to a seat plate portion 28. In the illustrated non-limiting embodiment, the locking member 82 is pivotally mounted to the seat plate portion 28, such as to the bottom of the seat plate portion 28. As shown, the locking member 82 may be a latch plate having an engagement assembly 84 and a release member 86. The engagement assembly 84 may be disposed at one end 88 of the latch plate 82 and may be shaped as a hook configured to engage a pin or shaft 90 located near the seat support surface 50. In one embodiment, a recess 92 is defined between the engagement assembly 84 and the release member 86. A biasing mechanism (not shown), such as a torsion spring, may be operably coupled to the latch plate 82. In one embodiment, the biasing mechanism is operable to bias the latch plate 82 toward a first locked position. Figure 4A In the first locked position, the pin 90, located on or near the seat support surface 70, is received in the recess 92 and / or engaged by the engagement assembly 84 of the latch plate 82.

[0082] The seat plate portion 28 further includes an actuator 100 operatively coupled to the booster locking mechanism 80. In the illustrated non-limiting embodiment, the actuator 100 is a release handle disposed on the outer surface of the seat plate portion 28, such as its seat support surface 50. The actuator 100 may be movable relative to the seat plate portion 28, for example, rotatable. The actuator 100 may be substantially flush with the seat support surface 50 of the seat plate portion 28 when not activated. In one embodiment, the axis of rotation of the actuator 100 is parallel to the axis of rotation of the latch plate 82. A portion of the actuator 100, such as its distal end 102, is configured to contact and rotate the latch plate 82 out of engagement with the pin 90. In the illustrated non-limiting embodiment, the actuator 100 is configured to engage the release member 86 of the latch plate 82. To operate the actuator 100, the actuator 100 is lifted, causing the actuator 100 to pivot about its axis to engage with the release member 86. Rotation of actuator 100 applies a force to release member 86, causing the entire latch plate 82 to rotate about its axis in a direction opposite to the biasing force of the biasing mechanism. This rotation of latch plate 82 moves engagement assembly 84 away from pin 90. Once pin 90 and engagement assembly 84 are separated, seat plate portion 28 can be separated from the remainder of child seat 24.

[0083] Although not typically shown, the child seat system 20 may additionally include a seatbelt assembly operable to secure a child within the child seat 24. A typical seatbelt assembly includes at least one shoulder strap or lap belt that can be connected to at least one crotch strap 120. (Reference) Figure 5 and 6 The crotch strap 120 is positioned between the occupant's legs and has a webbing 122 and a buckle 124 at its first end. Latches (not shown) associated with one or more waist belts and / or shoulder straps are configured to be releasably secured to the buckle 124 to secure the child in the child seat 24. In the illustrated non-limiting embodiment, a portion of the seat belt, such as the crotch strap 120, is connected to the seat plate portion 28 and is therefore detachable from the remainder of the child seat system 20 having the seat plate portion 28. Thus, the child seat is configured to accommodate the child only when the seat plate portion 28 is connected to the child seat 24. The second end 126 of the webbing 122 of the crotch strap 120 can be connected to the seat plate portion 28 via at least one anchor pin 128. This connection forms a rigid interface between the buckle 124 of the crotch strap 120 and the structure of the seat plate portion 28.

[0084] like Figure 3 and 5As shown, the seat portion 28 of the child seat 24 has a first strap receiving groove 130 and a second strap receiving groove 132 separate from the first strap receiving groove 130. In one embodiment, the first strap receiving groove 130 is positioned closer to the front 52 of the seat portion 28 than the second strap receiving groove 132, and / or the second strap receiving groove 132 is positioned closer to the rear 54 of the seat portion 28 than the first strap receiving groove 130. Furthermore, a connecting groove 134 may extend between and connect the first strap receiving groove 130 and the second strap receiving groove 132. In the non-limiting embodiment shown, the first strap receiving groove 130, the second strap receiving groove 132, and the connecting groove 134 combine to form an H-shape. A user can deploy the webbing 122 of the crotch strap 120 through the connecting groove 134 to reposition the webbing 122 between the first strap receiving groove 130 and the second strap receiving groove 132.

[0085] The webbing 122 of the crotch strap 120 can bypass either the first strap receiving slot 130 or the second strap receiving slot 132, depending on the size of the child in the child seat 24. The webbing 122 can bypass the auxiliary pin 136 before passing through the respective strap receiving slots 130, 132. The auxiliary pin 136 can be positioned between the first strap receiving slot 130 and the second strap receiving slot 132. In one embodiment, the auxiliary pin is generally aligned with or close to the back of the first strap receiving slot 130. When the webbing 122 is positioned at the first strap receiving slot 130, the webbing 122 extending from the anchor pin 128 passes under the auxiliary pin 136 and rotates approximately 90 degrees or less toward the first strap receiving slot 130. When the webbing 122 is positioned at the second strap receiving slot 132, the webbing 122 extending from the anchor pin 128 wraps around the auxiliary pin 136 approximately 180 degrees and extends rearward in the direction of the anchor pin 128 to the second strap receiving slot 132. In this way, the effective length of the webbing 122 extending from the second webbing receiving slot 132 is shorter than the effective length of the webbing 122 extending from the first webbing receiving slot 130. As used herein, "effective length" refers to the length of the webbing 122 extending beyond the seat support surface 50. This length can typically be measured perpendicular to the seat support surface 50. Therefore, when adjusting the crotch strap 120 for a larger child by repositioning the webbing 122 within the first webbing receiving slot 130, the webbing 122 is positioned away from the backrest and lengthened to extend away from the seat support surface 50.

[0086] In one embodiment, a recess 138 is formed at the seat support surface 50 of the seat plate portion 28. When the seat belt is not in use, such as when the seat plate portion 28 is separated from the backrest portion 26 of the child seat 24, the crotch buckle 124 can be received within the recess 138 for storage. In one embodiment, the crotch buckle 124 is shaped and positioned to define a portion of the seat support surface 50, such as when the crotch buckle 124 is received within the recess 138. In the non-limiting embodiment shown, the recess 138 is located near the actuator 100 associated with the booster locking mechanism 80. For example, the actuator 100 may have a general U-shape or C-shape, and the recess 138 may be defined within the C-shape. However, embodiments in which the recess 138 is formed at another suitable location (such as the front of the first belt receiving groove 130) are also contemplated herein.

[0087] Now for reference Figure 7 In the illustrated non-limiting embodiment, a portion of the seat belt, such as the lap belt and / or shoulder strap, is attached to the backrest portion 26 and / or support base 22 of the child seat 24. Therefore, the lap belt and / or shoulder strap remain attached to the child seat 24 even when the seat plate portion 28 is not attached to it. In one embodiment, a cavity 140 is formed in the upright support surface 30 of the backrest portion 26. A portion of the seat belt, such as a latch, located on or near the backrest portion 26 may be receptacleable within the cavity 140. Furthermore, a cover 142 may be movable relative to the cavity 140 to selectively seal the cavity 140.

[0088] Now for reference Figure 8A-11B In one embodiment, the backrest portion 26 of the child seat 24 includes a belt tensioner 150. In the illustrated non-limiting embodiment, an opening 152 is formed in the upright support surface 30, and the belt tensioner 150 is accommodating within the opening 152. The profile of the belt tensioner 150 may be complementary to the profile of the opening 152, such that the substantially integral of the belt tensioner 150 is accommodating within the recess 152. A vehicle belt (not shown) associated with the vehicle seat may be positioned along a belt accommodating path defined between the upright support surface 30 and the belt tensioner 150. In one embodiment, the belt tensioner 150 is selectively movable relative to the upright support surface 30 to adjust the tension applied to the vehicle belt along the vehicle belt accommodating path. For example, the belt tensioner 150 may be configured to be positioned around an open position ( Figure 8A ) and closing position ( Figure 8B At least one axis between the belt tensioner 150 and the opening 152 is pivoted to selectively tighten the portion of the vehicle belt clamped between the tensioner 150 and the opening 152 to connect the child seat 24 to the vehicle belt, thereby restricting the movement of the child seat 24 and the support base 22 relative to the vehicle seat.

[0089] The tensioner locking mechanism 154 can be used to secure the tensioner 150 in the closed position. For example... Figure 8A and 10 As shown, a pin or shaft 156 may be arranged within an opening 152 formed in the upright support surface 30. At least one groove 158 may be formed on the surface 160 of the tensioner 150 facing the opening 152, the groove 158 being aligned with the pin 156 and defining a path for receiving the pin. At least one locking claw 162 is movably mounted on the tensioner 150. Figure 11A-11B As shown, the locking pawl 162 has a throat 164 for receiving the pin 156 therein and at least one engagement feature 166 movable to engage with the pin 156 to limit the movement of the locking pawl 162 and thus the movement of the belt tensioner 150 relative to the backrest portion 26. In one embodiment, the locking pawl 162 is rotatable about an axis between an engaged position and a disengaged position. Furthermore, the locking pawl 162 can be biased toward the engaged position by a biasing mechanism (not shown).

[0090] As the tensioner 150 rotates toward the opening 152, the pin 156 is received within the slot 158 ​​and can engage the surface 168 of the locking pawl 162. In the illustrated non-limiting embodiment, the surface 168 of the locking pawl 162 is profiled, for example, inclined, such that the engagement between the pin 156 and the surface 168 counteracts the biasing force of the biasing member. Therefore, this engagement allows the locking pawl 162 to rotate from an engaged position to a disengaged position. Once the pin 156 reaches a specific position, such as once the pin 156 is received within the throat 164 of the locking pawl 162, the pin 156 no longer counteracts the biasing force of the biasing member. Therefore, the bias acting on the locking pawl 162 causes the locking pawl 162 to rotate into the engaged position.

[0091] Actuator 170 can be operatively coupled to locking pawl 162 to rotate locking pawl 162 to a disengaged position to release belt tensioner 150. While actuator 170 is shown positioned on belt tensioner 150, directly adjacent to belt tensioner locking mechanism 154, it should be understood that embodiments where actuator 170 is located away from belt tensioner are also within the scope of this disclosure. Actuator 170 can be associated with release member 172, such as a protrusion extending outward from the body of locking pawl 162. For example, in the non-limiting embodiment shown, actuator 170 includes a rib 174 movable to engage with release member 172. When a force is applied to actuator 170, such as when actuator 170 is rotated down, the force is transmitted to release member 172, as through rib 174. This force counteracts the bias of the biasing mechanism, thereby driving locking pawl 162 to rotate toward the disengaged position. In the disengaged position, the tensioner 150 can move away from the opening 152.

[0092] Continue to refer to Figure 1A-2And further reference Figure 12A and 12B The headrest 46 of the child seat 24 may include at least one strap guide 200, such as a shoulder strap guide, having an opening 202 to receive the vehicle strap therein. Thus, the opening 202 may define a portion of the vehicle strap path of the child seat 24. In the illustrated non-limiting embodiment, a first shoulder strap guide 200a with an opening 202a is arranged on a first side of the headrest 46, and a second shoulder strap guide 200b with an opening 202b is arranged on the opposite side of the headrest 46. The shoulder strap guides 200a and 200b may be integrally formed with the body 204 of the headrest 46, or alternatively, may be separate components fixed to the body. At least one shoulder strap guide 200 may be aligned and mounted to a portion of the headrest 46 and serve as an extension of that portion. For example, the body 204 of the headrest 46 may include a central body 206 and at least one headrest side member, such as a first headrest side member 208 and a second headrest side member 210 extending from the opposite side of the central body 206. At least one shoulder strap guide 200 may be positioned on the bottom surface of one or both of the first headrest side member 208 and the second headrest side member 210. The shoulder strap guide 200 may have a shape complementary to an adjacent portion of the headrest 46, such that the shoulder strap guide 200 is flush with the body 204 and defines a portion of the contour of the headrest 46. In the illustrated non-limiting embodiment, the first shoulder strap guide 200a is aligned with the first headrest side member 208, and the second shoulder strap guide 200b is aligned with the second headrest side member 210. At least one shoulder strap guide 200a, 200b may be permanently attached to the headrest 46, or alternatively, may be removably coupled to the headrest.

[0093] Refer again Figure 1A-2 And further reference Figure 13A and 13B As described herein, the headrest 46 of the child seat 24 may be movable relative to the upright support surface 30 of the child seat 24 between a retracted position and an extended position, thereby allowing adjustment according to the size of the child positioned within the child seat 24. A locking mechanism 220 operable to selectively lock the headrest 46 to a position relative to the child seat 24 typically includes an engagement component 222 associated with the headrest 46 and receivable within one of a plurality of openings or slots formed in a channel located on or adjacent to the upright support surface 30. As shown, a channel 224 having a plurality of slots 226 may be located on a side closer to the headrest 46, such as axially aligned with the engagement component 222. In the illustrated non-limiting embodiment, the engagement component is a ratchet or tooth 228 rotatable about an axis between a locked position in which the engagement component engages with the slots 226 and an unlocked position in which the engagement component 228 disengages from the plurality of slots 226.

[0094] The locking mechanism 220 may further include a connecting member 230 movably mounted to the headrest 46, and an engaging assembly 228 operably engages with the connecting member 230. In the illustrated non-limiting embodiment, a pin 232 extending from the engaging assembly 228 may be received within a slot 234 formed in the connecting member 230. A user may apply force to the connecting member 230 directly or indirectly. When force is applied, the connecting member 230 moves relative to the headrest 46, for example, by translation. This force is transmitted from the connecting member 230 to the engaging assembly 228 via a slotted engagement. Due to the orientation of the slot 234 relative to the direction of movement of the connecting member 230, the engaging assembly pivots and disengages from engagement with an adjacent slot 226 formed in the channel 224. In this unlocked position, the headrest 46 is movable between multiple positions.

[0095] A biasing mechanism 236 (such as a torsion spring or a coil spring) can be operatively coupled to the engaging assembly 228 and can bias the engaging assembly to engage with the adjacent slot 226a. In the illustrated non-limiting embodiment, the biasing mechanism 236 is operable to bias the connecting member 190 toward an inactive position. In such embodiments, the biasing mechanism 236 indirectly biases the engaging assembly to engage with the slot 226. However, in other embodiments, the biasing mechanism 236 can be directly coupled to the engaging assembly. Therefore, the force applied by the user to the connecting member 230 counteracts the biasing force of the biasing mechanism 236.

[0096] Now for reference Figure 14A and 14B In some embodiments, the child seat system 20 includes a latching system 240 comprising one or more latching connectors 242 operable to engage a corresponding anchor (not shown) of a vehicle seat to mount the child seat system 20 to the vehicle seat. Each latching connector 242 can be fastened to a suitable portion of the child seat system 20, such as a support base 22 or a portion of the seat housing 25, as by means of a strap or webbing 244. Each latching connector 242 can be in a closed or engaged configuration, such as by means of a release actuator (not shown) closing or extending a latching member 246 from which the latching connector 242 is located (e.g., Figure 14B The latch member 246 of the latch connector 242 (shown in the diagram) is convertible to an open or release configuration (not shown) in which the latch member 246 of the latch connector 242 is open or retracted, and is therefore detachable from the vehicle anchor.

[0097] In one embodiment, a cavity 250 may be formed at the child seat 24, such as at the backrest portion 26 of the seat housing 25, to receive or capture the corresponding latch connector 242 when disengaged from the vehicle seat anchor. In the illustrated non-limiting embodiment, such a cavity 250 is formed on the rear surface of at least one upright side member 36, 40. However, it should be understood that such a cavity 250 may be located at any suitable location around the child seat system 20, such as near the backrest portion 26 at the interface with the seat plate portion 28, or within the support base 22. As shown, a shaft 252 may be mounted inside the cavity 250, and the latch connector 242 may be operable to engage with the shaft 252 via a latching member 246, thereby engaging the latch connector 242 with the shaft 252 and restricting movement of the latch connector 242 from the cavity 250. Such a cavity 250 provides a storage means for managing the latch connector 242 when not in use.

[0098] Now for reference Figure 15A-16B The illustration shows a child seat system 300 with a support base 302 and a child seat 304 that can be attached to the support base 302. As previously described, the child seat 304 can be permanently attached to the support base 302, or alternatively, it can be removably attached to the support base. In either configuration, the child seat 304 can, but does not necessarily, be rotatable relative to the support base 302. As previously described, the child seat 304 can have a backrest portion 306 and a seat portion 308. The seat portion 308 can, but does not necessarily, be removably coupled to the backrest portion 306. In the non-limiting embodiment shown, an insert 310 can be positioned within the area of ​​the child seat 24 configured to accommodate a child. When installed, the insert 310 occupies additional space within the area of ​​the child seat 24 configured to accommodate a child so that the size of the area is adapted to the size of the child. The insert 310 can be configured for operation at multiple different stages, such as depending on the size and / or weight of the child that can be accommodated within the area of ​​the child seat. In one embodiment, different stages may be applied to children ranging from newborns to those weighing approximately 40 pounds.

[0099] In the illustrated non-limiting embodiment, insert 310 is an assembly comprising a first insert portion 312 and a second insert portion 314. The first insert portion 312 may include an elongated first central body 316 positioned to overlap at least a portion of the upright support surface 307 of the backrest portion 306 and at least a portion of the seat support surface 309 of the seat plate portion. The first central body 316 may have one or more creases or folds formed therein. As shown, a first seat side panel 318 and a second seat side panel 320 are connected to opposite sides of the first central body 316, such as near its first end. The first seat side panels 318 and 320 may be aligned with said portions of the first central body 316 configured to overlap with the seat support surface 309. The first seat side panels 318 and 320 may be movable, for example, rotatable relative to the first central body 316 to position the seat side panels 318, 320 relative to the seat side members of the seat plate portion 308.

[0100] The second insertion portion 314 similarly includes an elongated second central body 322 that can be positioned to overlap at least a portion of the upright support surface 307 and at least a portion of the seat support surface 309. Furthermore, a first upright side panel 324 and a second upright side panel 326 can be connected to opposite sides of the second central body 322, such as near its second end. The first upright side panel 324 and the second upright side panel 326 can be aligned with said portion of the first central body 322 configured to overlap with the upright support surface 307. For example, the first upright side panel 324 and the second upright side panel 326 can be movable, for example, rotatable relative to the second central body 322 to position the upright side panels 324, 326 relative to the upright side members of the backrest portion 306 of the child seat 304 or relative to the corresponding surface of the headrest 330. In one embodiment, the first upright side panel 324 and the second upright side panel 326 form a headrest for a child sitting on the insert 310.

[0101] In one embodiment, such as Figure 15A As shown, the second central body 322 further includes a first seat baffle 332 and a second seat baffle 334 disposed adjacent to its opposite ends. In such embodiments, the first seat baffle 332 and the second seat baffle 334 may be movable, for example, rotatable relative to the second central body 322, and may be positioned adjacent to the seat side members of the seat plate portion 308. As shown, the first seat baffle 332 and the second seat baffle 334, as well as the first upright side baffle 324 and the second upright side baffle 326 of the second insertion portion 314 may be disposed on the opposite sides of the first seat side baffle 318 and the second seat side baffle 320 of the first insertion portion 312.

[0102] In one embodiment, the length of the second central body 322 is less than the length of the first central body 316. However, embodiments in which the first central body 316 and the second central body 322 are substantially the same length or in which the second central body 322 is longer than the first central body 316 are also considered herein. As shown, corresponding openings 328a, 328b for accommodating a portion of the seat belt (such as the crotch strap 340) may be formed in both the first central body 316 and the second central body 322.

[0103] Insert portions 312 and 314 can be used in combination or individually depending on the desired stage of operation. When configured for the first stage, both the first insert portion 312 and the second insert portion 314 are mounted around the child seat 24. In the first stage, the insert 310 is intended for children weighing up to 11 pounds. The first insert portion 312 can be positioned near the interface between the backrest portion 306 and the seat plate portion 308, such that the first seat side panel 318 and the second seat side panel 320 contact a portion of both the seat side member and the upright side member. The second insert portion 314 can be aligned with the first insert portion 312. Thus, when using both insert portions 312 and 314, the first central body 316 and the second central body 322 (including the openings 328a and 328b formed therein) are arranged overlapping. In one embodiment, the second central body 322 is positioned upwards immediately adjacent to the first central body 316. However, embodiments in which the first central body 316 is located on top of the second central body 322 are also within the scope of this disclosure.

[0104] The insert 310 can also be configured for a second stage in which one of the insert portions has been removed. For example, in Figure 15B In the non-limiting embodiment shown, in the second stage, only the first insertion portion 312 is installed around the child seat 24. Alternatively, in the second stage, only the second insertion portion 314 may be installed around the child seat 24. When the first insertion portion 312 or the second insertion portion 314 (but not both) is installed, the insert 310 may be intended for use with children weighing from about 11 pounds to about 40 pounds. In one embodiment, when the child seat 24 is used with a child weighing more than 40 pounds, both the first insertion portion 312 and the second insertion portion 314 of the insert 310 are removed from the child seat 24.

[0105] Refer again Figure 1A-2The child seat system 20 may include at least one side impact protection device. The at least one side impact protection (SIP) device may be removably attached to the child seat system 20 by any suitable means, such as by double-sided tape, adhesive, or mechanical fasteners. Alternatively, the at least one SIP device may be permanently attached to or integrated with the child seat system, such that one or more SIP devices form an integral part with the structure of the backrest portion 26, the structure of the seat plate portion 28, or soft materials associated with the backrest portion 26 or the seat plate portion 28. As will be described in more detail below, one or more SIP devices may be installed at various locations around the support base 22 and / or the child seat 24. For example, the SIP device may be located at, for example, the seat plate portion 28, the backrest portion 26, or the headrest 46 of the child seat 24. Additionally, such a SIP device may be disposed on the inner or outer surface of the child seat 24.

[0106] The SIP device associated with the child seat system 20 can be formed of a material with a stiffness less than that of the seat shell 25. Using a material with reduced stiffness can facilitate the absorption of energy applied to the child seat system 20 during an accident, such as a side impact. In some embodiments, the stiffness of the material of the SIP device of the child seat system 20 is also greater than the stiffness of the soft material mounted around the seat shell 25 to provide additional energy absorption beyond that of the soft material. In one embodiment, the SIP device can be configured to have a sacrificial feature that is configured to break or deform during a collision to help absorb energy. In one embodiment, the SIP device is configured to move between a default position and an impact position to help absorb energy in a side impact event. The SIP device or a portion thereof can be formed of foam materials, such as expanded polypropylene (EPP), expanded polystyrene (EPS), and / or expanded polyolefin (EPO) with example densities of 30 g / l, 45 g / l, and 50 g / l. Various other materials and their specifications are considered.

[0107] Referring again to FIG1, in one embodiment, the child seat system 20 includes one or more head-injection devices 400a, 400b operable to restrain or control head movement of the occupant of the child seat system 20 during a side impact. The head-injection devices 400a, 400b may be disposed in an area of ​​the child seat 24 surrounding or adjacent to the occupant's head. In one embodiment, at least one head-injection device 400a, 400b is associated with and mounted to a headrest 46 of the child seat 24 in some embodiments. While the head-injection devices 400a, 400b are shown disposed on the inner surface of the headrest 46, in other embodiments, the head-injection devices 400a, 400b may be disposed on the outer surface of the headrest 46.

[0108] Alternatively or additionally, the child seat system 20 may also include one or more shoulder thrust devices 402a, 402b disposed on the inner surface of the child seat 24, operable to restrict or control movement of the shoulder of the occupant of the child seat system 20. Such shoulder thrust devices 402a, 402b, also referred to herein as “shoulder thrust devices,” may be disposed in areas of the child seat 24 that are generally aligned with and configured to contact the occupant’s shoulder or upper arm, such as at the backrest portion 26 of the child seat 24. In the illustrated non-limiting embodiment, a first shoulder thrust device 402a may be coupled to the bottom of a first headrest side member 47 and extend downward beyond said bottom, and a second shoulder thrust device 402b may be coupled to the bottom of a second headrest side member 49 and extend downward beyond said bottom. The shoulder thrust devices 402a, 402b may be movable relative to the seat body and headrest 46 of the child seat 24, such as between a first position and a second position.

[0109] Another SIP device suitable for use with a child seat is operable to restrict movement of the torso or hips of the occupant of the child seat. Such SIP devices 404a, 404b, which may be referred to herein as “torso SIP devices,” are typically arranged at the occupant-facing surface of the child seat 24, which is generally aligned with and configured to contact the occupant’s torso, located on the child seat (seat portion 28 or backrest portion 26). It should be understood that the torso SIP devices 404a, 404b as shown and described herein can be alternatively integrated into the child seat 24 in conjunction with or in combination with one or more of the head SIP devices 400a, 400b and shoulder SIP devices 402a, 402b as previously described herein. In embodiments of the child seat system 300 including insert 310, as Figure 15A-16B As shown, the baffles 318, 320, 324, and 326 associated with any of the insertion portions 312 and 314 can all be considered as torso SIP devices 404a and 404b.

[0110] The child seat system 20 may alternatively or additionally include one or more SIP devices 406 disposed on the side of the backrest portion 26 and may protrude outward, such as near the interface with the vehicle's track path. Such SIP devices 406, also referred to herein as "external SIP devices," may be disposed at the child seat, support base, or both. Furthermore, it should be understood that the external SIP devices 406, as shown and described herein, may alternatively or in combination with one or more of the head SIP devices, shoulder SIP devices, and torso SIP devices previously described herein, into the child seat. The external SIP devices 406 may be operable to limit or control interaction between the exterior of the child seat system 20 and adjacent parts of the vehicle, such as doors.

[0111] Now for reference Figure 17 and 18 This demonstrates another example of the child seat system 420. Similar to... Figure 1A-1E In the embodiment shown, the child seat system 420 includes a support base 422 and a child seat 424 associated with the support base 422. The child seat 424 may be permanently attached to the support base 422 or may be removably attached to the support base. The child seat 424 includes a backrest portion 426 and at least a portion of a seat plate portion 428 arranged at an angle relative to the backrest portion 426. The backrest portion 426 may be formed by a seat housing 425 of the child seat 424 and includes a backrest having a generally forward-facing upright support surface 430 extending from a first end or top 432 of the backrest portion 426 to a second opposite end or bottom 434 of the backrest portion 426. A first upright side member 436 may be arranged at a first side (not shown) of the upright support surface 430 and extend outward along the first side, and a second upright side member 440 may be arranged at a second opposite side 442 of the upright support surface 430 and extend outward along the second opposite side. Therefore, the first upright side member 436 and the second upright side member 440 form the left and right sides of the backrest portion 426, respectively. The first upright side member 436 and the second upright side member 440 may extend substantially orthogonally to the upright support surface 430, or alternatively, may extend from it at another angle, such as greater than 90°. Thus, the upright support surface 430 and the first upright side member 436 and the second upright side member 440 define a backrest area or upright support cavity in which a child's upper body is accommodated.

[0112] In the illustrated non-limiting embodiment, the backrest portion 426 of the child seat 424 includes a headrest 446. The headrest 446 may be attached to or integrated with the backrest portion 26, or may be removably coupled to said backrest portion. The headrest 446 may be fixed, or in some embodiments, may be configured to move relative to the upright support surface 430. For example, the headrest 446 may be configured to translate relative to the upright support surface 430 between a retracted position and an extended position, thereby allowing adjustment according to the size of the child positioned within the child seat 424.

[0113] The seat portion 428 of the child seat 424 may include a seat support surface 450, generally facing upwards, extending from a first end or front portion 452 to a second end or rear portion 454 of the seat portion 428. A first seat side member 456 may be disposed on a first side (not shown) of the seat support surface 450, and a second seat side member 460 may be disposed on a second opposite side 462 of the seat support surface 450. The first seat side member 456 and the second seat side member 460 extend upwards and from the left and right sides of the seat portion. The seat support surface 450 and the first seat side member 456 and the second seat side member 460 together define an area in which at least a portion of a child's lower body can be accommodated.

[0114] As shown, seat side members 456, 460 extend from seat support surface 450 at an angle. The angle of the first seat side member 456 relative to seat support surface 450 may, but does not necessarily, be the same as the angle of the first upright side member 436 relative to upright support surface 430. Similarly, the angle of the second seat side member 460 relative to seat support surface 450 may, but does not necessarily, be the same as the angle of the second upright side member 440 relative to upright support surface 430. In the illustrated non-limiting embodiment, each seat side member 456, 460 has a groove 466 formed therein, which is configured to act as a leg strap guide during at least one usage mode of the child seat 424. In some operating modes of the child seat 424, the groove 466 may be configured to receive and position the leg strap portion of a vehicle restraint or a separate restraint strap to secure the child within the child seat 424.

[0115] When the child seat 424 is installed in the vehicle, the upright side members 436, 440 can facilitate proper positioning of the vehicle strap during one or more operating modes. In the illustrated non-limiting embodiment, each upright side member 436, 440 has openings 444a, 444b formed therein, which are configured to receive the vehicle strap (not shown) to secure the child seat 424 to a forward-facing vehicle seat and / or to the upper body of a child located within the upright support cavity. Figure 17 and 18 The geometry of the openings 444a, 444b formed in the upright side members 436, 440 of the child seat 424, as shown in the non-limiting embodiment, is similar to... Figure 1A-1E The openings 44a and 44b of the child seat 24 are different. Figure 1A-1E In the non-limiting embodiment shown, the support 68 located at or associated with the upright side members 36, 40 (see...) Figure 1EThe support 68 is arranged at an angle to the upper portion 45 of the openings 44a and 44b. Therefore, the interface between the support 68 and the upper portion 45 of the openings 44a and 44b forms a sharp angle. Figure 17 and 18 In the non-limiting embodiment shown, the support 468 is modified to have a more curved profile, and therefore, the sharp corners at the interface between the support 468 and the upper portion 445 of the openings 444a, 444b are eliminated. However, the sharp corners have a relatively rounded configuration. It should be understood that any embodiment described herein with respect to child seat 24 is equally applicable to child seat 424.
