[0064] A detailed description of one or more embodiments of the disclosed apparatusand method are presented herein by way of exemplification and not limitation with reference to the Figures.

[0065] With reference now to the FIGS. 1A-2, an example of a child seat system 20 isillustrated. In each of the illustrated, non-limiting embodiments, the child seat system 20 includes a support base 22 that can be detachably fixed to a vehicle seat 10, such as via a latch or anchor mechanism, not shown in the FIGS. This latch or anchor system often used is sometimes referred to as a “lower anchor and tether for children” e.g., LATCH system. Alternatively, or in addition, the child seat system 20 may be detachably fixed to a vehicle seat 10 via a vehicle belt associated with the vehicle seat 10.WIA0176PCT (AP-24062-3520-WO000; C82401)

[0066] The child seat system 20 additionally includes a child seat 24 associated withthe support base 22. In an embodiment, the child seat 24 is detachably coupled to the support base 22, thereby allowing the child seat 24 to be separated from the support base 22. Alternatively, the support base 22 and at least a portion of the child seat 24 may be permanently connected or affixed together, as will be described in more detail below. As used herein the term “permanently connected” identifies embodiments where the child seat 24 or a portion thereof is not intended to be disassembled from the support base 22 by a user.

[0067] The child seat 24 includes a seat back portion 26 and at least a part of a seat panportion 28 arranged at an angle relative to the seat back portion 26. The seat pan portion 28 may but need not be configured to removably couple to the seat back portion 26. In the illustrated, non-limiting embodiments, the seat back portion 26 is formed by a seat shell 25 of the child seat 24 and includes a seat back having an upright support surface 30 generally facing forward and that extends from a first end or top 32 of the seat back portion 26 to a second, opposite end or bottom 34 of the seat back 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. The first and second upright side members 36, 40 therefore form the left side and the right side of the seat back portion 26, respectively. As shown, the first and second upright side members 36, 40 extend forward from the upright support surface 30. The first and second upright side members 36, 40 may extend generally orthogonally to the upright support surface 30 or alternatively, may extend therefrom at another angle, such as an angle greater than 90° for example. Accordingly, the upright support surface 30 and the first and second upright side members 36, 40 define a backrest region or upright support cavity within which an upper body of a child is received.

[0068] The upright side members 36, 40 may facilitate the correct positioning of avehicle belt during one or more modes of operation when the child seat 24 is installed within a vehicle. In some embodiments, each upright side member 36, 40 has an opening 44a, 44b formed therein. The openings 44a, 44b may be configured to receive a vehicle belt (not shown) to secure the child seat 24 to a vehicle seat 10 in a forward-facing configuration or to secure an upper body of a child located within the upright support cavity.

[0069] In the illustrated, non-limiting embodiments, the seat back portion 26 of thechild seat 24 includes a headrest 46. The headrest 46 may be attached to or integral with the seat back portion 26 or may be removably coupled thereto. The headrest 46 may be stationary, or in some embodiments, may be configured to move relative to the upright support surface 30.WIA0176PCT (AP-24062-3520-WO000; C82401) 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, allowing for adjustment based on the size of the child positioned within the child seat 24. However, it should be appreciated that embodiments here the seat back portion 26 does not include a headrest 46 are also contemplated herein.

[0070] The seat pan portion 28 of the child seat 24 may include a seat support surface50 facing generally upwardly and that extends from a first end or front 52 to a second end or back 54 of the seat pan portion 28. A first seat side member 56 may be arranged at a first side 58 of the seat support surface 50 and a second seat side member 60 may be arranged at a second, opposite side 62 of the seat support surface 50. The first seat side member 56 and the second seat side member 60 extend upwardly and from the left side and the right side of the seat portion. The seat support surface 50 and the first and second seat side members 56, 60 in combination define a region within which at least part of a lower body of a child may be received.

[0071] As shown, the seat side members 56, 60 extend at an angle from the seat supportsurface 50. The angle of the first seat side member 56 relative to the seat support surface 50 may but need not be the same as the angle of the first upright side member 36 relative to the upright support surface 30. Similarly, the angle of the second seat side member 60 relative to the seat support surface 50 may but need not be the same as the angle of the second upright side member 40 relative to the upright support surface 30.

[0072] In the illustrated, non-limiting embodiment, each seat side member 56, 60 has aslot 66 formed therein configured to function as a lap belt guide during at least one mode of use of the child seat 24. In some modes of operation of the child seat 24, the slot 66 may be configured to receive and position a lap belt portion of a vehicle restraint or a separate restraint belt to secure a child within the child seat 24.

[0073] The seat pan portion 28 of the child seat 24 may be removably connectable to aseat pan support surface 70 (see FIG. 2) of the child seat system 20. In the illustrated, non- limiting embodiment, the seat pan support surface 70 may be formed by a portion of the seat shell 25 located above the support base 22. However, in other embodiments, the seat pan support surface 70 may be a surface of the support base 22 itself such that the seat pan portion 28 is positionable directly adjacent to the support base 22. When separated from the remainder of the child seat system 20, the seat pan portion 28 may be configured as a booster seat positionable in direct contact with a vehicle seat and configured to support a child thereon. Although not shown, the seat pan portion 28 may include one or more positioning featuresWIA0176PCT (AP-24062-3520-WO000; C82401) configured to cooperate with one or more corresponding location features arranged at or extending from the seat pan surface or the seat back portion 26 near the seat pan surface. These positioning features and location features, in combination, are operable to properly locate the seat pan portion 28 relative to the seat pan support surface 70 during installation of the seat pan portion.

[0074] The booster seat may include a booster locking mechanism 80 operable toselectively couple the booster seat to the remainder of the child seat system 20. The booster locking mechanism 80 includes at least one locking member 82 movably mounted to the seat pan portion 28. In the illustrated, non-limiting embodiment, the locking member 82 is pivotally mounted to the seat pan portion 28, such as to an underside of the seat pan portion 28 for example. As shown, the locking member 82 may be a latch plate having an engagement member 84 and a release member 86. The engagement member 84 may arranged at an end 88 of the latch plate 82 and may be shaped like a hook configured to engage pin or shaft 90 located near the seat support surface 50. In an embodiment, a recess 92 is defined between the engagement member 84 and the release member 86. A biasing mechanism (not shown), such as a torsion spring for example, may be operably coupled to the latch plate 82. In an embodiment, the biasing mechanism is operable to bias the latch plate 82 toward a first, locked position (FIG.4A). In the first locked position, the pin 90 arranged at or proximate to the seat pan support surface 70 is received within the recess 92 and / or is engaged by the engagement member 84 of the latch plate 82.

[0075] The seat pan portion 28 additionally includes an actuator 100 operably coupledto the booster locking mechanism 80. In the illustrated, non-limiting embodiment, the actuator 100 is a release handle arranged at an exterior surface of the seat pan portion 28, such as the seat support surface 50 thereof. The actuator 100 may be movable, for example rotatable, relative to the seat pan portion 28. The actuator 100 may be substantially flush with the seat support surface 50 of the seat pan portion 28 when unactuated. In an 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 a distal end 102 thereof for example, 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 into engagement with the release member 86. The rotation of the actuator 100 applies a force to the release member 86, causing the entire latch plate 82 to rotate about its axis in a direction opposing the biasing force of the biasing mechanism. This rotation of theWIA0176PCT (AP-24062-3520-WO000; C82401) latch plate 82 moves the engagement member 84 away from the pin 90. Once the pin 90 and engagement member 84 are separated from one another, the seat pan portion 28 may be separated from the remainder of the child seat 24.

[0076] Although generally not shown, the child seat system 20 may additionallyinclude a harness assembly operable to secure a child within the child seat 24. Typical harness assemblies include at least one shoulder strap or waist strap connectable to at least one crotch strap 120. With reference to FIGS. 5 and 6, the crotch strap 120 is positionable between an occupant’s legs and has a piece of webbing 122 and a buckle 124 at a first end thereof. A latch (not shown) associated with the one or more waist straps and / or shoulder straps is configuredto releasably fasten to the buckle 124 to secure a child in the child seat 24. In the illustrated,non-limiting embodiment, a portion of the harness, such as the crotch strap 120 for example,is attached to the seat pan portion 28 and is therefore separable from the remainder of the child seat system 20 with the seat pan portion 28. Accordingly, the child seat 24 is only configured to receive a child when the seat pan portion 28 is connected thereto. A second end 126 of webbing 122 of the crotch strap 120 may be connected to the seat pan portion 28 via at least one anchor pin 128. Such a connection creates a rigid interface between the buckle 124 of the crotch strap 120 and the structure of the seat pan portion 28.

[0077] As shown in FIGS. 3 and 5, the seat pan portion 28 of the child seat 24 has afirst belt receiving slot 130 and a second belt receiving slot 132 separated from the first belt receiving slot 130. In an embodiment, the first belt receiving slot 130 is positioned closer to the front 52 of the seat pan portion 28 than the second belt receiving slot 132 and / or the second belt receiving slot 132 is positioned closer to the rear 54 of the seat pan portion 28 than the first belt receiving slot 130. Further, a connecting slot 134 may extend between and connect to both the first belt receiving slot 130 and the second belt receiving slot 132. In the illustrated, non- limiting embodiment, the first and second belt receiving slots 130, 132 and the connecting slot 134, in combination, form an H-shape. A user maneuver pass the webbing 122 of the crotch strap 120 through the connecting slot 134 to reposition the webbing 122 between the first belt receiving slot 130 and the second belt receiving slot 132.

[0078] The webbing 122 of the crotch strap 120 may be routed through either the firstbelt receiving slot 130 or the second belt receiving slot 132, depending on the size of the child seated within the child seat 24. The webbing 122 may be routed about a secondary pin 136 before passing through a respective belt receiving slot, 130, 132. The secondary pin 136 may be arranged between the first belt receiving slot 130 and the second belt receiving slot 132. In an embodiment, the secondary pin is generally aligned with or is proximate to a back side ofWIA0176PCT (AP-24062-3520-WO000; C82401) the first belt receiving slot 130. When the webbing 122 is arranged at the first belt receiving slot 130, the webbing 122 extending from the anchor pin 128 passes under the secondary pin 136 and rotates approximately 90 degrees or less thereabout toward the first belt receiving slot 130. When the webbing 122 is arranged at the second belt receiving slot 132, the webbing 122 extending from the anchor pin 128 wraps approximately 180 degrees about the secondary pin 136 and extends back in the direction of the anchor pin 128, to the second belt receiving slot 132. In this manner, the effective length of the webbing 122 extending out of the second belt receiving slot 132 is shorter than the effective length of the webbing 122 extending out of the first belt receiving slot 130. The “effective length” as used herein represents a length over which the webbing 122 extends beyond the seat support surface 50. This length may be measured generally perpendicularly to the seat support surface 50. Accordingly, when the crotch strap 120 is adjusted for a larger child by repositioning the webbing 122 within the first belt receiving slot 130, the webbing 122 is both positioned further away from the seat back and is lengthened to extend further away from the seat support surface 50.

[0079] In an embodiment, a recess 138 is formed at the seat support surface 50 of theseat pan portion 28. When the harness is not in use, such as when the seat pan portion 28 is separated from the seat back portion 26 of the child seat 24 for example, the crotch buckle 124 is receivable within the recess 138 for storage. In an 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 receive within the recess 138 for example. In the illustrated, non-limiting embodiment, the recess 138 is located adjacent to the actuator 100 associated with a booster locking mechanism 80. For example, the actuator 100 may have a general U or C-shape and the recess 138 may be defined at the interior of the C-shape. However, embodiments where the recess 138 is formed at another suitable location, such as forward of the first belt receiving slot 130 for example, are also contemplated herein.

[0080] With reference now to FIG. 7, in the illustrated, non-limiting embodiment, aportion of the harness, such as the waist and / or shoulder straps for example, are attached to the seat back portion 26 of the child seat 24 and / or to the support base 22. Accordingly, the waist and / or shoulder straps remain with the child seat 24 even when the seat pan portion 28 is not attached to the child seat 24. In an embodiment, a cavity 140 is formed in the upright support surface 30 of the seat back portion 26. Part of the harness located at or proximate to the seat back portion 26, such as the latches for example, may be receivable within the cavity 140. Further, a lid 142 may be movable relative to the cavity 140 to selectively seal the cavity 140.WIA0176PCT (AP-24062-3520-WO000; C82401)

[0081] With reference now to FIGS. 8A-11B, in an embodiment, the seat back portion26 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 receivable within the opening 152. A contour of the belt tensioner 150 may be complementary to that of the opening 152 such that the substantial entirety of the belt tensioner 150 is receivable within the opening 152. A vehicle belt (not shown) associated with the vehicle seat is positionable along a belt receiving path defined between the upright support surface 30and the belt tensioner 150. In an 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 receiving path. For example, the belt tensioner 150 may be configured to pivot about at least one axis between an open position (FIG.8A) and a closed position (FIG.8B) to selectively tension the portion of the vehicle belt sandwiched between the belt tensioner 150 and the opening 152 to couple the child seat 24 to the vehicle belt, thereby restricting movement of the child seat 24 and support base 22 relative to the vehicle seat.

[0082] A belt tensioner locking mechanism 154 may be used to retain the belt tensioner150 in the closed position. As shown in FIG. 8A and 10, a pin or shaft 156 may be arranged within the opening 152 formed in the upright support surface 30. At least one slot 158 may be formed at the surface 160 of the belt tensioner 150 facing the opening 152, the slot 158 being aligned with and defining a path for receiving the pin 156. At least one locking pawl 162 is movably mounted to the belt tensioner 150. As shown in FIGS.11A-11B, the locking pawl 162 has a throat 164 for receiving the pin 156 therein and at least one engagement feature 166 movable into engagement with the pin 156 to restrict movement of the locking pawl 162, and therefore the belt tensioner 150, relative to the seat back portion 26. In an embodiment, the locking pawl 162 is rotatable about an axis between an engaged position and a disengaged position. Further, the locking pawl 162 may be biased by a biasing mechanism (not shown) toward the engaged position.

[0083] As the belt tensioner 150 is rotated towards the opening 152, the pin 156 isreceived within the slot 158 and may engage a surface 168 of the locking pawl 162. In the illustrated, non-limiting embodiment, the surface 168 of the locking pawl 162 is contoured, for example sloped, such that the engagement between the pin 156 and the surface 168 opposes the biasing force of the biasing member. Accordingly, this engagement may rotate the locking pawl 162 from the engaged position toward the disengaged position. Once the pin 156 reaches a specific location, such as once the pin 156 is received within the throat 164 of the locking pawl 162 for example, the pin 156 no longer opposes the biasing force of the biasing member.WIA0176PCT (AP-24062-3520-WO000; C82401) As a result, the bias acting on the locking pawl 162 causes the locking pawl 162 to rotate into the engaged position.

[0084] An actuator 170 may be operably coupled to the locking pawl 162 to rotate thelocking pawl 162 to the disengaged position to release the belt tensioner 150. Although the actuator 170 is illustrated as being located at the belt tensioner 150, directly adjacent to the belt tensioner locking mechanism 154, it should be appreciated that embodiments where the actuator 170 is located remotely therefrom are also within the scope of the disclosure. The actuator 170 may be associated with a release member 172, such as a protrusion extending outwardly from the body of the locking pawl 162. For example, in the illustrated, non-limiting embodiment, the actuator 170 includes a rib 174 movable into engagement with the release member 172. When a force is applied to the actuator 170, such as when the actuator 170 is rotatably depressed for example, the force is transmitted to the release member 172, such as via the rib 174. The force opposes the bias of the biasing mechanism thereby driving rotation of the locking pawl 162 toward the disengaged position. In the disengaged position, the belt tensioner 150 may be moved away from the opening 152.

[0085] With continued reference to FIGS.1A-2 and further reference to FIGS.12A and12B, the headrest 46 of the child seat 24 may include at least one belt guide 200, such as a shoulder belt guide for example, having an opening 202 for receiving a vehicle belt therein. Accordingly, the opening 202 may define a portion of a vehicle belt path of the child seat 24. In the illustrated, non-limiting embodiment, a first shoulder belt guide 200a having an opening 202a is arranged at a first side of the headrest 46 and a second shoulder belt guide 200b having an opening 202b is arranged at an opposite side of the headrest 46. The shoulder belt guide 200a, 200b may be integrally formed with the body 204 of the headrest 46, or alternatively, may be a separate component affixed thereto. The at least one shoulder belt guide 200 may be mounted in alignment with and as an extension of a portion of the headrest 46. 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 and second headrest side member 208, 210 extending from opposite sides of the central body 206. At least one shoulder belt guide 200 may be positioned at a bottom surface of one or both of first and second headrest side members 208, 210. The shoulder belt guide 200 may have a shape complementary to the adjacent portion of the headrest 46 such that the shoulder belt 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, a first shoulder belt guide 200a is aligned with the first headrest side member 208 and a second shoulder belt guide 200b is aligned with the second headrest side member 210. The at least one shoulder belt guide 200a,WIA0176PCT (AP-24062-3520-WO000; C82401) 200b may be permanently affixed to the headrest 46, or alternatively, may be removably couplable thereto.

[0086] With reference again to FIGS. 1A-2 and further reference to FIGS. 13A and13B, the headrest 46 of a child seat 24 as described herein may be movable relative to the upright support surface 30 of the child seat 24 between a retracted position and an extended position, allowing for adjustment based on the size of the child positioned within the child seat 24. A locking mechanism 220 operable to selectively lock the headrest 46 in 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 at or adjacent to the upright support surface 30. As shown, a channel 224 having a plurality of slots 226 may be located near a side of the headrest 46, such as in axial alignment 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 is engaged with a slot 226 and an unlocked position in which the engagement component 228 is separated from the plurality of slots 226.

[0087] The locking mechanism 220 may additionally include a linking member 230movably mounted to the headrest 46 and the engagement component 228 may be operably coupled to the linking member 230. In the illustrated, non-limiting embodiment, a pin 232 extending from the engagement component 228 is receivable within a slot 234 formed in the linking member 230. A user can apply a force, either directly or indirectly, to the linking member 230. When a force is applied thereto, the linking member 230 moves, for example translates, relative to the headrest 46. This force is transmitted from the linking member 230 to the engagement component 228 via the slotted engagement. As a result of the orientation of the slot 234 relative to the direction of movement of the linking member 230, the engagement component is pivoted out of engagement with an adjacent slot 226 formed in the channel 224. In this unlocked position, the headrest 46 is movable between a plurality of positions.

[0088] A biasing mechanism 236, such as a torsion or coil spring for example, may beoperably coupled to engagement component 228 and may bias engagement component into engagement with an adjacent slot 226a. In the illustrated, non-limiting embodiment, the biasing mechanism 236 is operable to bias the linking member 190 toward an unactuated position. In such embodiments, the biasing mechanism 236 indirectly biases the engagement component into engagement with a slot 226. However, in other embodiments, the biasing mechanism 236 may be directly coupled to the engagement component. Accordingly, application of a force by a user to the linking member 230 opposes the bias of the biasing mechanism 236.WIA0176PCT (AP-24062-3520-WO000; C82401)

[0089] With reference now to FIGS. 14A and 14B, in some embodiments the child seatsystem 20 includes a latch system 240 including one or more latch connectors 242 operable to engage a corresponding anchor of a vehicle seat (not shown) to mount the child seat system 20 to the vehicle seat. Each latch connector 242 may be tethered, such as via a strap or webbing 244 to a suitable portion of the child seat system 20, such as the support base 22 or a portion of the seat shell 25. Each latch connector 242 may be transformable, such as via a release actuator (not shown), from a closed or engaged configuration in which a catch member 246 of the latch connector 242 is closed or extended (as shown in FIG.14B), and an open or released configuration in which the catch member 246 of the latch connector 242 is open or retracted (not shown) and therefore separable from a vehicle anchor.

[0090] In an embodiment, a cavity 250 for stowing or capturing a respective latchconnector 242 when separated from a vehicle seat anchor may be formed at the child seat 24, such as at the seat back portion 26 of the seat shell 25 for example. In the illustrated, non- limiting embodiment, such a cavity 250 is formed at a back 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 about the child seat system 20, such as at the seat back portion 26 near the interface with the seat pan portion 28, or in the support base 22 for example. As shown, a shaft 252 may be mounted within the interior of the cavity 250 and the latch connector 242 may be operable to engage the shaft 252 via the catch member 246, thereby coupling the latch connector 242 to 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 connectors 242 when not in use.

[0091] With reference now to FIGS.15A-16B, a child seat system 300 having a supportbase 302 and a child seat 304 connectable to the support base 302 is illustrated. As previously noted, the child seat 304 may be permanently connected to the support base 302, or alternatively, may be removably connectable thereto. In either configuration, the child seat 304 may but need not be rotatable relative to the support base 302. The child seat 304 may have a seat back portion 306 and a seat pan portion 308 as previously described herein. The seat pan portion 308 may but need not be removably couplable to the seat back portion 306. In the illustrated, non-limiting embodiment, an insert 310 is positionable within the area of the child seat 24 configured to receive the child. When installed, the insert 310 occupies extra space within the area of the child seat 24 configured to receive the child to adapt the size of the area to that of the child. The insert 310 may be configurable for operation in a plurality of different stages, such as based on the size and / or weight of the child receivable within the area of theWIA0176PCT (AP-24062-3520-WO000; C82401) child seat. In an embodiment, the different stages may be adapted for use with a child ranging from a newborn up to about 40 pounds.

[0092] In the illustrated, non-limiting embodiment, the insert 310 is an assemblyincluding a first insert portion 312 and a second insert portion 314. The first insert portion 312 may include an elongated first central body 316 positionable in overlapping arrangement with at least part of the upright support surface 307 of the seat back portion 306 and at least part of the seat support surface 309 of the seat pan portion. The first central body 316 may have one or more creases or folds formed therein. As shown, a first and second seat side flap 318, 320 are connected to opposite sides of the first central body 316, such as near a first end thereof. The first and second seat side flaps 318, 320 may be aligned with the portion of the first central body 316 configured to overlap the seat support surface 309. The first and second seat side flaps 318, 320 may be movable, for example rotatable relative to the first central body 316 to position the seat side flaps 318, 320 against the seat side members of the seat pan portion 308.

[0093] The second insert portion 314 similarly includes an elongated second centralbody 322 positionable in overlapping arrangement with at least part of the upright support surface 307 and at least part of the seat support surface 309. Further, a first and second upright side flap 324, 326 may be connected to opposite sides of the second central body 322, such as near a second end thereof. The first and second upright side flaps 324, 326 may be aligned with the portion of the first central body 322 configured to overlap the upright support surface 307. The first and second upright side flaps 324, 326 may be movable, for example rotatable relative to the second central body 322 to position the upright side flaps 324, 326 against the upright side members of the seat back portion 306 of the child seat 304 or against a corresponding surface of the headrest 330 for example. In an embodiment, the first and second upright side flaps 324, 326 form a headrest for a child seated upon the insert 310.

[0094] In an embodiment, as shown in FIG. 15A, the second central body 322additionally includes first and second seat flaps 332, 334 disposed adjacent to the opposite end thereof. In such embodiments, the first and second seat flaps 332, 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 pan portion 308. As shown, the first and second seat flaps 332, 334 and the first and second upright side flaps 324, 326 of the second insert portion 314 may be disposed at opposite sides of the first and second seat side flap 318, 320 of the first insert portion 312.

[0095] In an embodiment, the length of the second central body 322 is less than thelength of the first central body 316. However, embodiments where the first central body 316WIA0176PCT (AP-24062-3520-WO000; C82401) and the second central body 322 are substantially equal in length or where the second central body 322 is longer than the first central body 316 are also contemplated herein. As shown, a respective opening 328a, 328b for receiving a portion of a harness, such as a crotch belt 340 for example, may be formed in both the first central body 316 and the second central body 322.

[0096] The insert portions 312, 314 may be used in combination or independentlybased on a desired stage of operation. When configured for use in a first stage, the first insert portion 312 and the second insert portion 314 are both installed about the child seat 24. In the first stage, the insert 310 is intended for use with a child up to 11 pounds. The first insert portion 312 may be arranged adjacent to the interface between the seat back portion 306 and the seat pan portion 308 such that the first and second seat side flaps 318, 320 are in contact with a portion of both the seat side members and the upright side members. The second insert portion 314 may be installed in alignment with the first insert portion 312. Accordingly, the first central body 316 and the second central body 322, including the openings 328a, 328b formed therein, are in overlapping arrangement when both insert portions 312, 314 are being used. In an embodiment, the second central body 322 is positioned upwardly adjacent to the first central body 316. However, embodiments where the first central body 316 is located on top of the second central body 322 are also within the scope of the disclosure.

[0097] The insert 310 may also be configured for use in a second stage in which one ofthe insert portions has been removed. For example, in the illustrated, non-limiting embodiment of FIG.15B, only the first insert portion 312 is installed about the child seat 24 in the second stage. Alternatively, only the second insert portion 314 may be installed about the child seat 24 in the second stage. When either the first insert portion 312 or the second insert portion 314 (but not both) is installed, the insert 310 may be intended for use with a child having a weight between about 11 pounds and about 40 pounds. In an embodiment, both the first insert portion 312 and the second insert portion 314 of insert 310 are removed from the child seat 24 when the child seat 24 is being used by a child exceeding 40 pounds.

[0098] With reference again to FIGS. 1A-2, the child seat system 20 may include atleast one side impact protection device. The at least one side impact protection (SIP) device may be removably connected to the child seat system 20 in any suitable manner, such as via double-sided tape, adhesive, or a mechanical fastener for example. Alternatively, the at least one SIP device may be permanently connected to or integral therewith, such that the one or more SIP devices and the structure of the seat back portion 26, the structure of the seat pan portion 28, or the soft goods associated with either the seat back portion 26 or the seat pan portion 28, form a single unitary part. As will be described in more detail below, the one orWIA0176PCT (AP-24062-3520-WO000; C82401) more SIP devices may be mounted at various locations about the support base 22 and / or the child seat 24. For example, an SIP device may be located at the seat pan portion 28, the seat back portion 26, or the headrest 46 of the child seat 24 for example. Further, such an SIP device may be arranged at an interior surface or an exterior surface of the child seat 24.

[0099] An SIP device associated with the child seat system 20 may be formed from amaterial having a hardness less than the hardness of the seat shell 25. The use of a material having a reduced hardness may facilitate the absorption of energy applied to the child seat system 20 during an accident, such as a side impact collision. In some embodiments, the material of an SIP device of the child seat system 20 also has a hardness greater than the hardness of the soft goods mounted about the seat shell 25 to provide additional energy absorption beyond that of the soft goods. In an embodiment, an SIP device may be constructed with sacrificial features that are configured to break or deform during a collision to help absorb energy. In an embodiment, an SIP device is configured to move between a default position and an impact position to help absorb energy during a side impact event. An SIP device or portions thereof may be formed of foam materials such as expanded polypropylene (EPP), expanded polystyrene (EPS), and / or expanded polyolefin (EPO) with example densities such as 30 g / l, 45 g / l, and 50 g / l. Various other materials and specifications thereof are contemplated.

[0100] With continued reference to FIG. 1, in an embodiment, the child seat system 20includes one or more SIP devices 400a, 400b operable to restrict or control movement of the head of an occupant of the child seat system 20 during a side impact collision. The head SIP device 400a, 400b may be arranged at an area of the child seat 24 surrounding or located adjacent to an occupant’s head. In an embodiment, the at least one head SIP device 400a, 400b is associated with, and in some embodiments is mounted to, the headrest 46 of the child seat 24. Although the head SIP devices 400a, 400b are shown arranged at an interior surface of the headrest 46, in other embodiments, a head SIP device 400a, 400b may be arranged at an exterior surface of the headrest 46.

[0101] Alternatively, or in addition, the child seat system 20 may also include one ormore SIP devices 402a, 402b arranged at an interior surface of the child seat 24 operable to restrict or control movement of a shoulder of an occupant of the child seat system 20. Such SIP devices 402a, 402b, also referred to herein as “shoulder SIP devices” may be arranged at areas of the child seat 24, such as the seat back portion 26 of the child seat 24 for example, generally aligned with and configured to contact an occupant’s shoulder or upper arm. In the illustrated, non-limiting embodiment, a first shoulder SIP device 402a may be coupled to and extends downwardly beyond a bottom of a first headrest side member 47, and a second shoulder SIPWIA0176PCT (AP-24062-3520-WO000; C82401) device 402b may be coupled to and extend downwardly beyond a bottom of a second headrest side member 49. The shoulder SIP devices 402a, 402b are movable with the headrest 46 relative to the seat body of the child seat 24, such as between a first position and a second position.

[0102] Another SIP device suitable for use with a child seat is operable to limitmovement of the torso or hips of an occupant of the child seat. Such SIP devices 404a, 404b may be referred to herein as “torso SIP devices,” with these devices typically being arranged at an occupant facing surface of the child seat 24 at an area of the child seat (either the seat pan portion 28 or the seat back portion 26) generally aligned with and configured to contact an occupant’s torso. It should be understood that torso SIP devices 404a, 404b as illustrated and described herein may be integrated into a child seat 24 as an alternative to, 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 a child seat system 300 including an insert 310, such as shown in FIGS. 15A-16B, the flaps 318, 320, 324, 326 associated with either insert portion 312, 314 may be considered torso SIP devices 404a, 404b.

[0103] The child seat system 20 may alternatively or additionally include one or moreSIP devices 406 arranged at a lateral side of the seat back portion 26 and may protrude outwardly therefrom, such as near an interface with a vehicle belt path. Such an SIP device 406 also be referred to herein as an “external SIP device” may be arranged at a child seat, a support base, or both. Further, it should be understood that an external SIP device 406 as illustrated and described herein may be integrated into a child seat as an alternative to, or in combination with one or more of a head SIP device, a shoulder SIP device, and a torso SIP device as previously described herein. An external SIP device 406 may be operable to limit or control an interaction between an exterior of the child seat system 20 and an adjacent part of a vehicle, such as a vehicle door for example.

[0104] With reference now to FIGS. 17 and 18, another example of a child seat system420 is illustrated. Similar to the embodiment shown in FIGS.1A-1E, 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 connected to or may be removably couplable to the support base 422. The child seat 424 includes a seat back portion 426 and at least a part of a seat pan portion 428 arranged at an angle relative to the seat back portion 426. The seat back portion 426 may be formed by a seat shell 425 of the child seat 424 and includes a seat back having an upright support surface 430 generally facing forward and that extends from a first end or top 432 of the seat back portion 426 to a second, opposite end or bottom 434 of the seat back portion 426. A first upright side member 436 may be arranged at a first side (not shown) of theWIA0176PCT (AP-24062-3520-WO000; C82401) upright support surface 430 and extend outwardly therefrom and a second upright side member 440 may be arranged at a second, opposite side 442 of the upright support surface 430 and extend outwardly therefrom. The first and second upright side members 436, 440 therefore form the left side and the right side of the seat back portion 426, respectively. The first and second upright side members 436, 440 may extend generally orthogonally to the upright support surface 430 or alternatively, may extend therefrom at another angle, such as an angle greater than 90° for example. Accordingly, the upright support surface 430 and the first and second upright side members 436, 440 define a backrest region or upright support cavity within which an upper body of a child is received.

[0105] In the illustrated, non-limiting embodiments, the seat back portion 426 of thechild seat 424 includes a headrest 446. The headrest 446 may be attached to or integral with the seat back portion 26 or may be removably coupled thereto. The headrest 446 may be stationary, 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, allowing for adjustment based on the size of the child positioned within the child seat 424.

[0106] The seat pan portion 428 of the child seat 424 may include a seat support surface450 facing generally upwardly and that extends from a first end or front 452 to a second end or back 454 of the seat pan portion 428. A first seat side member 456 may be arranged at a first side (not shown) of the seat support surface 450 and a second seat side member 460 may be arranged at 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 upwardly and from the left side and the right side of the seat portion. The seat support surface 450 and the first and second seat side members 456, 460 in combination define a region within which at least part of a lower body of a child may be received.

[0107] As shown, the seat side members 456, 460 extend at an angle from the seatsupport surface 450. The angle of the first seat side member 456 relative to the seat support surface 450 may but need not be the same as the angle of the first upright side member 436 relative to the upright support surface 430. Similarly, the angle of the second seat side member 460 relative to the seat support surface 450 may but need not be the same as the angle of the second upright side member 440 relative to the upright support surface 430. In the illustrated, non-limiting embodiment, each seat side member 456, 460 has a slot 466 formed therein configured to function as a lap belt guide during at least one mode of use of the child seat 424. In some modes of operation of the child seat 424, the slot 466 may be configured to receiveWIA0176PCT (AP-24062-3520-WO000; C82401) and position a lap belt portion of a vehicle restraint or a separate restraint belt to secure a child within the child seat 424.

[0108] The upright side members 436, 440 may facilitate the correct positioning of avehicle belt during one or more modes of operation when the child seat 424 is installed within a vehicle. In the illustrated, non-limiting embodiment, each upright side member 436, 440 has an opening 444a, 444b formed therein configured to receive a vehicle belt (not shown) to secure the child seat 424 to a vehicle seat in a forward-facing configuration and / or to secure an upper body of a child located within the upright support cavity. The openings 444a, 444b formed in the upright side members 436, 440 of the child seat 424 shown in the non-limiting embodiment of FIGS.17 and 18 have a different geometry than the openings 44a, 44b of the child seat 24 of FIGS. 1A-1E. In the non-limiting embodiment shown in FIGS. 1A-1E, a support 68 (see FIG.1E) located at or associated with the upright side member 36, 40 is arranged at an angle relative to an upper portion 45 of the opening 44a, 44b. Accordingly, an interface between the support 68 and the upper portion 45 of the opening 44a, 44b forms a sharp corner. In the non- limiting embodiment illustrated in FIGS.17 and 18, the support 468 has been modified to have a more arcuate contour, and as a result, the sharp corner at the interface between the support 468 and the upper portion 445 of the opening 444a, 444b has been eliminated. Rather, the interface has a generally rounded configuration.
