DETAILED DESCRIPTION

[0178] The following description presents exemplary embodiments and, together with the drawings, serves to explain principles of the disclosure. However, the scope of the invention is not intended to be limited to the precise details of the embodiments, since variations will be apparent to a skilled person and are deemed also to be covered by the description. Terms for components used herein should be given a broad interpretation that also encompasses equivalent functions and features. In some cases, alternative terms for structural features may be provided but such terms are not intended to be exhaustive.

[0179] Descriptive terms should also be given the broadest possible interpretation; e.g. the term “comprising” as used in this specification means “consisting at least in part of” such that interpreting each statement in this specification that includes the term “comprising”, features other than that or those prefaced by the term may also be present. Related terms such as “comprise” and “comprises” are to be interpreted in the same manner. Directional terms such as “vertical”, “horizontal”, “up”, “down”, “top”, “bottom”, “upper” and “lower” are used for convenience of explanation usually with reference to the illustrations and are not intended to be ultimately limiting if an equivalent function can be achieved with an alternative dimension, orientation and/or direction.

[0180] The description herein refers to embodiments with particular combinations of features, however, it is envisaged that further combinations and cross-combinations of compatible features between embodiments will be possible. Indeed, isolated features may function independently as an invention from other features and not necessarily require implementation as a complete combination.

[0181] The general descriptive terms “child car seat” and “pram” related to the field of the disclosure are also not intended to be limiting. In the present field there are a wide range of terms applicable to the present disclosure and can be used interchangeably to describe the device, without affecting its scope and interpretation. For example, a “child car seat” can be a catch-all term for a safety device used by a baby, toddler or child for both sitting and/or laying down in a flat position, e.g. a booster seat or carrier respectively. The term “pram” used herein if intended to be a reference to a perambulator, buggy, pushchair, stroller, umbrella folding stroller or carriage.

[0182] The first child car seat system 1 comprises a docking module 2, in combination with a detachable infant carrier module 3 arranged to be docked in nested relationship with the docking module 2, and lifted from the docked condition to separate from the docking module 2. The car seat system 1 is intended to provide a single system that can be used to enable a child to be safely secured in a vehicle from an infant right through to an age of up to six years. The docking module 2 provides a base seat that can be secured in the vehicle by ISOFIX fixings. The infant carrier module 3 provides a means for securing the infant in the vehicle (by means of a three-point adult seat belt and also by connection to the docking module 2) and also be demountable to be used as an infant carrier. When secured nested with the docking module 2, the infant carrier module 3 can be reconfigured, for infant comfort, between a lie-flat configuration and an upright configuration. The lie-flat position is the nominal seat angle from birth to approximately 6 months. Then as the baby grows, a support panel or platform 33 is moved from the lie-flat position towards a more upright position and the harness and head support 32 moves up. This will be described in detail. Importantly, as the child grows, the car seat system can be reconfigured to accommodate the larger child, by incorporating the infant carrier module in modified form into the car seat system for the older child, and securing the child with a three-point adult seat belt in the vehicle.

[0183] In the figures, the docking module 2 is shown in combination with the docked infant carrier module 3 in FIGS. 7 to 12 and 15. The infant carrier module 3 is shown on its own in FIGS. 1 to 6 and 14. The docking module alone is shown in FIG. 13.

[0184] Referring to FIG. 13, the docking module 2 is in the form of a base seat frame having a backrest portion 2a and a seat portion 2b which curves away from the backrest portion 2a. Referring to FIGS. 7 to 12 also, the docking module base seat frame carries latch hooks 5 which are connected to rotatable bars 6 mounted to the base seat frame. The latch hooks 5 are rotatable to a locked position, in order to secure the infant carrier module nested into the docking module base seat frame 2. This is the configuration shown in FIGS. 7 to 10 in which the latches 5 are shown hooked over engaged with a lock bar 15 carried on the underside of the infant carrier module 3. Conversely the bar 6 is rotatable to a release position in which the latch hooks 5 are disengaged from the lock bar 15 and the infant carrier module 3 can be lifted out of nested engagement with the base seat frame docking module 2. Similar latch hooks 5 provided on the backrest portion 2a of the base seat frame docking module 2 are rotatable to engage and disengage with a similar short lock bars 17, provided on the underside of the back-rest portion of the infant carrier module 3. The short lock bars 17 extend between flanges 19 provided on the rear/underside of the infant carrier 3. The latch hooks 5 are provided on rotatable bars 18. In FIGS. 9 and 11 the latch hooks 5 on the docking module back rest 2a are shown engaged (and therefore out of view).

[0185] Internally of the docking module 2 are a pair of spaced parallel sub-frame members 7. Sub-frame members 7 provide the chassis of the base frame docking module in combination with a spaced pair of frame members 16. Sub-frame members 7 are provided with arcuate slots 20 within which a follower bar 8 connected to the spaced frame members 16 can slide. This enables the frame members 16 to slide with respect to the sub-frame members 7 to reconfigure the docking module between a reclined condition (as shown in the figures) and an upright seated position. This reconfiguration ability is primarily intended for use to enable reclining and upright orientation when the seat system is in the older child mode.

[0186] The docking module seat 2 is provided with an adjustable extendible headrest 22 mounted slidably to the frame members 16 and provided with openings for receiving straps of a five-point harness 23. The five points of anchor for the harness 23 are shown as a, b, c, d, and e. Harness anchor points a, b, c, and d are provided on the docking module seat. Harness anchor point e is a buckle 24 connected to the infant carrier module by means of a buckle strap 25 connected to a load bar 15 provided on-board the infant carrier module. The harness 23 is for use when the seat system 1 is converted for older child mode. This configuration is shown in FIG. 12. When in infant seat mode there is a harness system 30 provided on the infant carrier module (see FIG. 14). The older child five-point harness system 23 is, when the system is configured for carrying an infant, stowed between the docking module 2 and the infant carrier module 3. It is of note that when in infant or child carrier mode, the buckle 24 connected to the infant carrier module 3 is used.

[0187] The infant carrier module 3, as shown in FIG. 2, comprises a plastics moulded main body 37 to which is mounted a carry handle 31. The carry handle 31 is demountable from the main body 37 at the juncture at which the system is converted from an infant car seat to an older child, car seat system. The infant carrier module includes an infant support platform 33, which extends between an infant carrier headrest 32 and a sliding footplate 39. Hinge connections 34, 35 are provided connecting the support platform 33 and the headrest 32 and footplate 39 respectively. This permits the support platform 33 and the headrest 32 of the infant carrier to be tilted between a relatively flat position (shown in FIG. 3) and a relatively upright position (shown in FIG. 5). An intermediate position is shown in FIG. 4. The footplate 39 is provided with an aperture 36 through which the buckle strap 25 protrudes and permits the footplate 39 to slide toward or away from the carrier front lip 38, as the support platform re-orientates between the relatively flat, and upright positions. As the support platform 33 re-orientates, the hinge connection 34 slides along the guide slot 41.

[0188] The infant carrier module is used as such until the infant grows to a sufficient extent. At this point, a one-time conversion is undertaken in which the carry handle is removed and the infant carrier harness system 30 stowed, for example within the internal fabric of the infant carrier module 3 (or behind the infant carrier module). Removal of the carry handle enables the primary, docking module seat harness system 23 to be accessed via the openings 41. Following this conversion, the car seat system 1 is used in toddler mode with the carrier module 3, effectively being permanently docked with the docking seat module. This configuration is shown for example in FIG. 12, where it can be seen that the infant headrest 32 is removed from the infant carrier module, and the toddler headrest is used which is permanently fitted to the seat system 1 whether in infant or toddler mode.

[0189] The infant carrier module 3 provides a means for securing the infant in the vehicle by means of connection to the docking module 2, and also be demountable to be used as an infant carrier. When secured nested with the docking module 2, the infant carrier module 3 can be reconfigured, for infant comfort, between a lie-flat configuration and an upright configuration. In this mode the platform 33 can also be adjusted to a range of intermediate positions between lie-flat and upright. As the child grows, the car seat system can be reconfigured to accommodate the larger child, in a one-time conversion, by incorporating the infant carrier module in modified form into the car seat system for the older child.

[0190] The car seat system can be used in combination with a pram system to provide further versatility. The pram system is shown in FIGS. 16 and 17. In FIG. 16, there is shown a pram 45 which has relatively large rear wheels 46, compared to the forward wheels of the pram. The rear wheels are also set outwardly of the forward wheels to provide enhanced stability. The pram is utilised with the infant carrier module 3 of the car seat system which is arranged to clip to the pram frame in any manner that is known in the art, either in place of the seat 49 or over the seat 49. The rear axle of the frame and also the front lower frame and the handle of the frame are formed using clampable telescoping joints 47, 50 and 51 respectively. A brake 48 is provided acting via a cable arrangement on the rear wheels 46.

[0191] The pram mode configuration is shown in FIG. 17. The frame can be expanded using the clampable telescoping joints 47, 50, 51. The large rear pram wheels 46 are removed and replaced with smaller wheels that sit more closely to the stanchions 43. This can clearly be seen by comparison of FIGS. 16 and 17.

[0192] FIG. 18 is a side view of a child car seat system 100 with an infant carrier module 200 and a docking module 300. Any or each of the features discussed above with reference to FIGS. 1 to 17 may also be incorporated into this child car seat system and are not discussed again for brevity.

[0193] The child car seat system 100 includes an infant carrier module 200 and a docking module 300. An infant may be positioned in the infant carrier module 200. The infant carrier module 200 includes a seat portion 210 and a backrest portion 220 rotationally attached thereto. The relative rotation of the seat portion 210 and the backrest portion 220 is discussed in more detail with reference to FIGS. 19 and 20. A release actuator 230 is provided on a rear side of the backrest portion 220. Actuating the release actuator 230 unlocks the hinge connecting the seat portion 210 and the backrest portion 220 and allows the relative inclination between seat portion 210 and the backrest portion 220 to be adjusted. The release actuator 230 may be incorporated into a seat belt guide.

[0194] The infant carrier module 200 also includes a headrest 240, as illustrated in FIGS. 24A-24C, and a carrier handle 250. An infant may be positioned in the infant carrier module 200 with their bottom and legs supported by the seat portion 210, their back and arms supported by the backrest portion 220, and their head supported by the headrest 240. The headrest 240 is slidably adjustable between a first headrest position, shown in FIG. 24A, a second headrest position, shown in FIG. 24B, and a third headrest position, shown in FIG. 24C. As the child grows, the position of the headrest 240 can be adjusted. The headrest 240 can be locked into position to prevent accidental adjustment of the headrest 240 height.

[0195] An integral upholstered portion may be provided covering the seat portion 210, the backrest portion 220 and the headrest 240, for comfort. An integral harness may also be provided to secure the infant into the infant carrier module 200. The harness may be stowable within the infant carrier module 200 when not in use. The infant carrier module 200, and an infant positioned therein, may be carried by way of the carrier handle 250. The carrier handle 250 may be adjustable rotationally in angle relative to the seat portion 210 and/or the backrest portion 220.

[0196] The carrier handle 250 can be removed from the infant carrier module 200, as illustrated in FIG. 25. The infant carrier module 200 comprises a carrier handle locking clip 260 and a carrier handle locking member 270 located on a carrier handle connecting portion 280. In a first configuration, the carrier handle locking clip 260 and a carrier handle locking member 270 are in a locked mode, wherein the carrier handle 250 is locked to the infant carrier module 200. A portion of the carrier handle locking member 270 passes through the carrier handle 250, securing the carrier handle 250 against the carrier handle connecting portion 280. In a second configuration, the carrier handle 250 can be removed from the infant carrier module 200.

[0197] To remove the carrier handle 250 from the infant carrier module 200, a user can manually release the carrier handle locking clip 260, allowing the carrier handle locking member 270 to rotate 90 degrees relative to the carrier handle connecting portion 280. In this second configuration, wherein the carrier handle locking member 270 is normal to the carrier handle connecting portion 280, the handle bar 250 can be moved in direction D. In this way, the carrier handle locking member 270 no longer passes through a portion of the carrier handle 250, such that the carrier handle 250 can be entirely removed from the infant carrier module 200. The carrier handle 250 allows the infant carrier module 200, and an infant positioned therein, to be carried by way of the carrier handle 250. However, wherein the carrier handle 250 is removably retained on the infant carrier module 200, the infant carrier module 200 can easily be docked to the docking module 300 with or without the carrier handle 250.

[0198] The infant carrier module 200 may be releasably docked in the docking module 300. The docking module 300 includes a shell portion 310, into which the infant carrier module 200 may be docked, and a base portion 320, which supports the shell portion 310. The shell portion 310 includes four locking guides, as illustrated on FIGS. 28 and 29. The four locking guides 380 form a locking mechanism 380 that engages with the infant carrier module 200, as the infant carrier module 200 is docked, to ensure that the infant carrier module 200 is positioned and aligned correctly to engage with a locking mechanism 380, and possibly a further locking mechanism, if provided. The infant carrier module 200 is docked by lowering the infant carrier module 200 in direction E onto the docking module 300. The locking mechanisms 380 (and the further locking mechanism, if provided) releasably attaches the infant carrier module 200 to the shell portion 310. Each of the locking guides includes a locking hook that locks the infant carrier module 200 automatically when the shell portion 310 is rotated into a position intended for travel. The shell portion 310 is similarly shaped to the infant carrier module 200 such that, when docked, the infant carrier module 200 fits relatively snugly within the shell portion 310. The shell portion 310 provides protection and additional security to the infant carrier module 200.

[0199] The shell portion 310 is rotatable within the base portion 320 about an axis running approximately vertically in the view shown in FIG. 18. The shell portion 310 is shown in a rearward facing direction, but the shell portion 310 may be arranged in any orientation, such as forward facing or sideways facing. The shell portion 310 may be lockable in a rearward facing direction or a forward facing direction, as is typically used when travelling. The locking mechanisms 380 (and the further locking mechanism, if provided) are configured such that the carrier module 200 is only locked in the docking position when it is in a rearward or forward facing position. Further, the locking mechanisms 380 (and the further locking mechanism, if provided) are configured such that the locking mechanisms 380 (and the further locking mechanism, if provided) automatically locks when the carrier module 200 is docked in the rearward or forward facing position. A rotation release button may be provided on one or more sides of the docking module 300 to release the rotational locking positions. Additionally, the shell portion 310 may be reclinable within the base portion 320. In particular, the shell portion 310 may be reclinable within the base portion 320 when the shell portion 310 is arranged in the forward facing arrangement, for comfort. The shell portion 310 further comprises a manual release member 370 for manually locking and releasing the infant carrier module 200 to the docking module 300. The manual release member 370 is operable only when the carrier module 200 is in an unreclined configuration, as shown in FIG. 26. In this way, the manual release member 370 acts as a secondary safety lock.

[0200] As illustrated in FIG. 27, the base portion 320 includes ISOFIX latches 330 to allow the base portion 320 to be securely connected to a vehicle. ISOFIX installation levers 340 are and cause the ISOFIX latches 330 to slide out when pressed. In some examples, the levers 340 may instead be buttons. ISOFIX sliders 350 are provided to decouple the ISOFIX connectors 330. When installed, the ISOFIX sliders 350 will indicate that the ISOFIX latches 330 are correctly installed, and may be slid to decouple the ISOFIX latches 330.

[0201] The docking module 300 also includes a support leg 360 configured to extend from the base portion 320 to the floor of the vehicle. The support leg 360 may be rotatably attached to the base portion 320 such that the support leg is movable between an extended position, as shown in FIG. 18, and a stowed position wherein the support leg 360 lies adjacent to the base portion 320. The extended position of the support leg 360 is further shown in FIG. 22 and the stowed position of the support leg 360 is illustrated in FIG. 23. As the support leg 360 can be stowed away adjacent to the base portion 320 as the child grows, this allows the docking module 300 to be reconfigured to accommodate the larger or older child.

[0202] FIG. 19 is a side view of the infant carrier module 200 of FIG. 18 arranged in the upright position. In the upright position, the seat portion 210 and the backrest portion 220 are relatively inclined at an angle between 120° and 90°, such as approximately 100°.

[0203] Accordingly, an infant positioned in the infant carrier module 200 may be sitting in an upright position. The relative inclination between the seat portion 210 and the backrest portion 220 may be adjusted by way of the release actuator 230, such that the infant carrier module may be arranged in the lie flat position, as shown in FIG. 20.

[0204] FIG. 20 is a side view of the infant carrier module 200 of FIG. 18 arranged in the lie flat position. In the lie flat position, the seat portion 210 and the backrest portion 220 are relatively inclined at an angle greater than that of the upright position. Accordingly, an infant positioned in the infant carrier module 200 may be lying in a flat position. The relative inclination between the seat portion 210 and the backrest portion 220 may be adjusted by way of the release actuator 230, such that the infant carrier module may be arranged in the upright position, as shown in FIG. 19.

[0205] The infant carrier module 200, as shown in FIGS. 19 and 20, includes a connector portion 215 between the seat portion 210 and the backrest portion 220. As can be seen in FIGS. 19 and 20, the connector portion 215 remains static when the seat portion 210 and the connector portion 220 move. The carrier handle, as discussed with reference to FIG. 18, is rotatably and releasably connected to the connector portion 215. The connector portion 215 may also include sockets or protrusions configured to engage with a wheeled frame, as discussed with reference to FIG. 21, to attach the infant carrier module 200 to the wheeled frame and form a pram. Additionally, the connector portion 215 includes a belt guide 216 on each side of the infant carrier module 200. The belt guides 216 are configured to receive and retain a seatbelt or lap belt of a vehicle therein. As such, the infant carrier module 200 may be secured in a vehicle with the integrated seatbelt or lap belt of the vehicle.

[0206] FIG. 21 is a perspective view of a wheeled frame 400 for use with the infant carrier module of FIG. 18. The wheeled frame 400 includes a telescopic handle section 410 attached to a front wheel section 420 via locking hinges 430. A portion of the handle section 410 may be moved telescopically into or out of another portion to reduce or increase a height of the handle section 410. The handle section includes a locking and unlocking actuator 440 positioned at a proximal end of the handle section 410 intended to be held by a user when pushing or pulling the wheeled frame 400. The locking actuator 440 may be used to lock or unlock the telescopic function of the handle section 410, in particular by sliding or rotating a portion of the locking actuator 440.

[0207] The wheeled frame 400 also includes a rear wheel section 450 attached to the front wheel section 420 via the locking hinges 430. The locking hinges 430 may therefore be three way hinges. The wheeled frame 400 may be arranged in a pram configuration, as shown in FIG. 21, wherein the handle portion 410 and the front wheel portion 420 are substantially linear and the rear wheel section 450 extends away from the handle section 410 and the front wheel section 420 to form a generally ‘T’ shaped frame. Alternatively, the hinges 430 may be released and the wheeled frame 400 may be arranged in a collapsed arrangement in which the handle section 410, the front wheel section 420 and the rear wheel section 450 are adjacent to each other. The collapsed arrangement may be particularly suitable when transporting the wheeled frame 400. To collapse the wheeled frame, a user may perform a second actuation on the locking actuator 440, such as sliding or rotating a second component, or rotating the first component in a different direction and releasing the secondary, which may be achieved via a sliding button on the handle portion 410 or otherwise.

[0208] Each of the sideways connecting frame members, shown as the horizontal members in FIG. 21, of the wheeled frame 400 may be adjustable in length to adjust a width of the wheeled frame 400. The sideways connecting frame members may be telescopic or otherwise length adjustable. The locking actuator 440 may be actuated in a third manner to release a sideways locking of the wheeled frame 400 to allow for the width of the wheeled frame 400 to be adjusted.

[0209] The rear wheel section 450 includes rear wheels 460. The rear wheels 460 are releasably attached such that they are replaceable. The rear wheels 460 may be removed individually. Alternatively, the rear wheels 460 may be removed as a pair along with the connecting axle. A relatively large set of rear wheels 460 are shown in FIG. 21. Relatively large wheels may provide a more comfortable ride than relatively smaller wheels. Relatively smaller replacement wheels may be provided, such as a set of wheels equivalent in size to the wheels of the front wheel section 420.

[0210] The infant carrier module 200 shown in FIGS. 18 to 20 may be attached to the wheeled frame to form a pram, depending on the configuration of the components. The infant carrier module 200 may attach to the wheeled frame 400 at points adjacent to the attachment points of the carrier handle 250 of the infant carrier module 200, for stability. The infant carrier module 200 may attach to the wheeled frame 400 between the locking hinges 430, without the need for additional adapters. The angle at which the infant carrier module 200 is supported by the wheeled frame 400 may be adjustable. The infant carrier module 200 and/or the wheeled frame 400 may include a bumper bar which may be adjustable in angle along with the backrest of the infant carrier module 200. The bumper bar may be releasably attached to the seat portion of the pram, which may be formed by the infant carrier module 200. A collapsible and stowable canopy may also be provided to cover or shade the infant carrier module 200.

[0211] Additionally or alternative features and/or arrangements may be provided, as will be clear from the full disclosure made herewith. In particular, features described with reference to any aspects of the disclosure, or the other systems described, may be incorporated into any of the other aspects or disclosures.

[0212] FIG. 30 is a perspective view of structural components of the docking module 300 shown in FIG. 18. The shell portion (not shown) includes two substantially parallel curved frame members 311 separated and held apart by a plurality of cross members 312. The frame members 311, 312 provide a stiff and supportive backbone to the shell portion and to an infant positioned in the child car seat system. The locking guides 380 are connected to the frame members 311, 312 and extend through the shell portion to guide the infant carrier module (not shown) into the correct position for docking. The docking module includes four locking latches 381 connected in two pairs of two latches. The locking latches 381 are configured to hook over corresponding components on the rear of the infant carrier module (not shown) to hold the infant carrier module adjacent to the docking module 300.

[0213] FIG. 31 is an exploded view of the infant carrier locking system shown in FIG. 30. FIG. 32 is an enlarged view of the infant carrier locking system shown in FIG. 30. FIG. 33 is a sectional view of the infant carrier locking system shown in FIG. 30. As shown in FIG. 30, the locking system includes locking latches 381. The locking latches have hooked ends configured to hook over corresponding components on the rear of the infant carrier module. The hooked ends of each pair face towards each other to ensure a secure connection is provided. The locking latches 381 are operated by a paddle 383 rotatable relative to a locking housing 384 that is fixed to the docking module 300. Actuating the paddle 383 operates and rotates locking levers 385, which in turn pull on locking wires 386. The locking wires 386 are connected to the locking latches 381 and, when the locking wires 386 are pulled, pull on locking latches 381 and rotate the locking latches 381 such that the hooked ends are held away from the corresponding components on the infant carrier module. Although wires are depicted, any other suitable component may be provided. When the hooked ends are moved away from the corresponding components on the infant carrier module, the infant carrier module may be undocked from the docking module 300.

[0214] Rotation of the shell portion within the base portion 320 to a sideward facing direction, as described above, may cause the paddle 383 to press against a part of the base portion 320, such as a release moulding 387 protruding from a top surface of the base portion 320, and be actuated automatically. With the shell portion positioned to face sideward, the locking latches 381 are held apart or open such that the infant carrier module may be docked or undocked freely. As and when the shell portion is rotated away from the sideward facing direction toward a forward or rearward facing direction, the paddle 383 disengages from the release moulding 387 and the locking latches 381 hook over the corresponding components on the rear of the infant carrier module to retain the infant carrier module in a docked configuration. A second paddle 383 and corresponding linkage members, operationally identical to that described above, is provided to actuate, lock and unlock the locking latches 381 on the opposite side of the release moulding 387.

[0215] FIG. 34 is an exploded view of the support leg 360 shown in FIG. 18. The support leg 360 is connected to the base portion (not shown) via a support leg bracket 361A, a pivot bracket 361B and a support leg pivot bar 361C. The support leg bracket 361A is configured to be fixed to the base portion of the docking module. The support leg 360 is pivotable about the support leg bracket 361A via the pivot bracket 361B and the support leg pivot bar 361C. The pivot bracket 361B and the support leg pivot bar 361C are arranged such that the support leg 360 is able to move through at least 90° of rotational motion, from a stowed position to a deployed or extended position. The support leg 360 comprises an upper support leg 362A and a lower support leg 362B that is telescopically received within the upper support leg 362A such that the support leg 360 is length adjustable. A support leg end cap 363A is provided to cover the lower end of the lower support leg 362B, and upper foot moulding 363B and lower foot moulding 363C are provided adjacent to the support leg end cap 363A to form an enlarged foot having desirable support and gripping properties.

[0216] Various housings and covers, including support leg upper nose moulding 364A, support leg lower nose moulding 364B, rear upper cover 364C and support leg release housing 364D are provided to cover the mechanical connections of the support leg 360 for safety and improved aesthetics.

[0217] The support leg 360 is securable in a plurality of lengths. A support leg locking pin 365 engages with the upper support leg 362A and the lower support leg 362B to prevent relative movement and adjustment of the length of the support leg 360. A support leg release button 366, on a rear side of the support leg 360, is actuable by a user to release the support leg locking pin 365 and allow for relative movement between the upper support leg 362A and the lower support leg 362B to adjust the length of the support leg 360. A spring 367 is provided to bias the upper support leg 362A away from the lower support leg 362B. A further spring may be provided to bias the support leg locking pin 365 into a position in which adjustment of the length of the support leg 360 is prevented.

[0218] The support leg upper nose moulding 364A and support leg lower nose moulding 364B combine to form a nose. The nose carries the pivot bar 361C such that the support leg 360 is pivotable about the nose. The nose is slidably attached to the docking module along an axis perpendicular to the upper support leg 362A and generally left to right in the arrangement shown in FIGS. 34 and 35. The nose may translate between a fully retracted position, in which the nose mouldings 364A, 364B are generally flush with the housing of the docking module, and a fully extended position in which the nose mouldings 364A, 364B protrude from the docking module. The nose may be securable in a plurality of positions at and/or between the fully retracted and fully extended positions.

[0219] In use, a user may deploy the support leg 360 by pivoting the support leg 360 about the pivot bar 361C, extend the nose to the fully extended position, and position the docking module on the vehicle seat, press the support leg release button 366 to disengage the locking pin 365 and adjust the length of the support leg 360 such that the lower foot moulding 363C presses against the floor of the vehicle. The nose may be at least partially retracted from the fully extended position for reasons other than to correctly position the support leg 360.

[0220] FIG. 35 is a sectional view of a lower end of the support leg 360 shown in FIG. 18. The support leg 360 includes a pressure activated switch 368 that is set when a sufficient pressure above a threshold level is applied by the support leg 360, via the lower foot moulding 363C, to the floor of the vehicle. The switch 368 may then be activated when the pressure falls below the threshold level and provide an output. The output from the switch 368 may be used to provide a visual and/or audible notification to the user that the support leg 360 is correctly set up for use within a vehicle.

[0221] FIG. 36 is a sectional view of a recline system of the docking module shown in FIG. 18, and FIG. 37 is an exploded view of the recline system shown in FIG. 36. A recline handle 390 positioned on an underside of the shell portion between the two frame members 311. Pulling the recline handle 390 in the direction of arrow 391 causes locking pins 392 to be withdrawn from through holes in recline plates 393, such that the infant carrier module is no longer held in the current recline position and may be repositioned in a sliding manner between an upper and a recline position. Accordingly, a more comfortable arrangement may be provided, particularly for a relatively young infant.

[0222] A recline housing 396 is attached to the frame members 311 via a front locking pivot 395A and a lower recline bar 395B. The front locking pivot 395A and lower recline bar 395B pass through a recline housing 396 and hold the recline housing 396 adjacent to the frame members 311. Recline slides 397 are positioned between the recline housing 396 and each frame member 311 to allow for controlled sliding when the system is reclined. Once the system has been positioned in the desired recline position, the locking pins 392 may reengage with the recline plates 393 and hold the system securely in the desired recline position.

[0223] FIG. 38 is a sectional view of the ISOFIX assembly 500, FIG. 39 is a further sectional view of the ISOFIX assembly 500 shown in FIG. 38, and FIG. 40 is an exploded view of the ISOFIX assembly 500 shown in FIG. 38. The ISOFIX assembly 500 includes latches 502 configured for attachment to the vehicle in which the system is installed. The latches 502 are provided at the end of an extendable arm 504 that is moveable between a retracted position and a fully extended position. A spring 506 and elongate spring support 507 are provided to bias the arm 504 towards the fully extended position. A ratchet 508A and pawl 508B system is provided to hold the arm 504 at one of a plurality of intermediate positions between the retracted position and the fully extended position, such that further extension of the arm 504 is prevented.

[0224] The ISOFIX assembly 500 also includes a ratchet release lever 340. as discussed with reference to FIGS. 18 and 27, arranged to disengage the pawl 508B from the ratchet 508A and allow the arm 504 to extend. A slide bush 512, ratchet bush 514 and arm slide plate 516 are provided to allow for precise and smooth sliding of the arm 504 into and out of a housing 518.

[0225] To release a latch 502 from the vehicle mounting, a release button 520 and a secondary release lock 522 are provided. The secondary release lock 522 allows for the release button 520 to be actuated, and without the secondary release lock 522 being held, the release button 520 is unable to be actuated.

[0226] In use, a user may release the ratchet 508A such that the arm 504 extends out, biased by spring 506, to the fully extended position. This is done by pressing or actuating the ratchet release lever 340, which disengages the pawl 508B such that the spring 506 is free to move the arm 504. The user may then attach the latch 502 to the vehicle mounting points. The user may then push the base portion up against the back portion of the vehicle seat, causing the arms 504 to be at least partially retracted, and the ratchet 508A and pawl 508B interlock to hold the arms 504 at the desired length. To release the latches 502, the user must push and hold the secondary release lock 522 and then push the release button 520. This two factor release mechanism reduces the risk of accidental disengagement.

[0227] FIG. 41 is an exploded view of an infant carrier handle 250 assembly of the infant carrier module shown in FIG. 18, and FIG. 42 is a sectional view of the infant carrier handle 250 assembly shown in FIG. 41. The handle 250 is rotatable and securable in four positions via a rotatable locking cam arrangement. Other numbers of positions are envisaged. The handle assembly includes a rotation locking cam 251 including two opposed cam arms that is receivable within a corresponding handle location boss 252, including four tooth forms, arranged on the car seat. When the locking cam 251 is arranged within the location boss 252, rotation of the handle 250 relative to the remainder of the car seat is prevented. A locking cam spring 253 is provided to bias the locking cam 251 into a locked arrangement such that, at rest, rotation of the handle 250 is prevented. In order to adjust the position of the handle, a user may press and hold a handle adjustment button 254 provided on both sides of the system, which moves the locking cam 251 out of engagement with the location boss 252 and allow for rotation of the handle 250. Once the user releases the button, a release spring 255 biases the button 254 into a depressed state, such that the locking cam 251 may reengage with the location boss 252 at a different tooth form, or the next available tooth form if between two adjacent tooth forms, and hold the handle 250 in the desired position.

[0228] FIG. 43 is an exploded infant carrier handle removal system 530 of the infant carrier module shown in FIGS. 18 and 25, and FIG. 44 is a sectional view of the infant carrier handle removal system shown in FIG. 43, provided such that a user may remove the handle from the infant carrier module. The handle removal system 530 includes an inner handle moulding 532 configured to fit in a corresponding depression on the rear of the infant carrier module to locate the handle correctly. A corresponding outer handle moulding 534 is provided to cover the inner handle moulding 532 and the internal mechanisms of the handle removal system 530. A handle locking cam 535 is rotatably attached at one end and is rotatable by a user to release the handle such that the handle may be removed. A secondary handle lock 536 is provided to cover the free end of the handle locking cam 535 and hold the handle locking cam 535 in a locking position. The secondary handle lock 536 is slidable away from the handle locking cam 535, such that the handle locking cam 535 may be rotated, and is biased into a locking position in which the secondary handle lock 536 engages with the handle locking cam 535 by a handle locking spring 537.

[0229] To remove the handle, a user must first slide the secondary handle lock 536 away from the handle locking cam 535, against the action of the spring 537, before rotating handle locking cam 535 out approximately 90° away from the rear of the infant carrier module. The handle is therefore unlocked and may be removed.

[0230] FIG. 45 is a sectional view of a headrest 240 adjustment system of the infant carrier module shown in FIG. 18, and FIG. 46 is an exploded view of the headrest 240 adjustment system shown in FIG. 45. The headrest 240 is moveable generally in the direction of arrow 241 such that, as an infant grows and becomes taller, the system may be adapted to better suit the infant. The headrest 240 is moveable in the direction of arrow 241 via two separate movement mechanisms.

[0231] The first movement mechanism is activated by pulling a release handle 242A to unlock locking pins 243A, via release wire 242B, which engage with a headrest carrier plate 244A to hold the headrest 240 stationary. Locking slides 243B are provided for each locking pin 243A. A headrest front carrier plate 244B and headrest retaining plate 244C are also provided to form a stable and secure structure for the headrest 240. The second mechanism is operable once the headrest 240 has reached the maximum possible movement via the first mechanism. The second mechanism is activated by pushing secondary headrest lever 245, allowing the headrest 240 to move to a further point.

[0232] FIG. 47 is a side sectional view of a headrest 240 interlock system of the child car seat system shown in FIG. 18. The headrest 240 is slidably attached to the backrest portion of the infant carrier module 200 and is slidable away from the infant carrier module 200 such that the headrest 240 overhangs the top of the backrest portion. As described previously, the docking module 300 includes slots into which substantially mushroom shaped protrusions 246, extending from a rear surface of the headrest 240, are received. The slots include a first portion having a width larger than a greatest diameter of the mushroom shaped protrusion 246 such that the protrusions 246 may enter the slots, and a second portion having a width that is lesser than the greatest diameter of the protrusions 246. In this way, the protrusions 246 cannot be removed from the second portion of the slots. Crash loads may therefore be transferred throughout the entire system.

[0233] FIG. 48 is a sectional view of a rotation system 540 of the docking module 300 shown in FIG. 18, and FIG. 49 is an exploded view of the rotation system 540 shown in FIG. 48. The rotation system 540 is provided to allow the shell portion 310 to rotate relative to the base portion 320 of the docking module 300. The rotation system 540 includes activation buttons 541 operable to release a rotation lock 542 that cooperates with a rotation plate 543 to selectively prevent rotation of the shell portion 310 relative to the base portion 320. The rotation lock 542 is held within a rotation lock housing 544 and is moved by a solenoid 545, operable by the activation buttons 541, which rotates a rotation activation cam 546 to withdraw the rotation lock 542 from the rotation plate 543. The recline plates, as discussed with reference to FIGS. 36 and 37, are attached to the rotation plate 543.

[0234] The rotation system 540 is activated by pushing either of the activation buttons 541 on the top of the base portion 320. This activates the solenoid 545 which pushes the activation cam 546, which in turn pulls the rotation lock 542 out of the rotation plate 543 and allows the shell portion 310 to rotate on the base portion 320. The solenoid 545 is configured to hold the lock 542 open for 3 to 5 seconds, thus allowing the shell portion 310 to be rotated by a user. The lock 542 is spring biased so that, following the deactivation of the solenoid 545, the lock 542 will automatically engage with the rotation plate 543 and prevent further rotation of the shell portion 310 when the shell portion 310 is arranged to face forwards or rearward. The assembly 540 also forms the metal load path with rotation hooks 547 hooking over the rotation plate 543, therefore allowing crash loads to be transferred throughout the system and to the vehicle via the ISOFIX connectors.

[0235] FIG. 50 is an exploded view of the infant carrier module 200 of FIG. 18. Only the external shells or supporting structures of the seat portion 210, the backrest portion 220 and the connector portion 215 are shown. A lie flat activation button 230 is provided on a rear of the shell of the backrest portion 220 in a seating aperture 211. An outer ring or cover 212 is provided to encircle and cover the lie flat activation button 230. Pressing the lie flat activation button 230 pulls a locking plunger 213 away from a tooth form in the shell of the backrest portion 220, thereby disengaging the lie flat locking mechanism. In particular, when a user presses the button 230, the button 230 actuates an activation lever 214 which pulls the plunger 213 via wire 219. The locking plunger 213 is biased towards the tooth form by a spring 217. Other components and actuators are envisaged and will be apparent from the present disclosure. The assemblies are connected by two connecting arms 218A, 218B. The connecting arms 218A, 218B allow the movement of the backrest portion 220 to drive movement of the seat portion 210, and/or an upholstered component positioned thereon.

[0236] FIG. 51 is a schematic view of a rotation limiter 600 in a first position. The rotation limiter 600 may be positioned between the shell portion and the base. The rotation limiter 600 includes a rotatable selector 610 coupled to two lobes 620 having an outer edge that is curved such that the two lobes 620 together form a substantially elliptical outer surface. The selector 610 is rotatable about an axis that is parallel or coaxial with an axis about which the shell portion may rotate on the base portion, parallel to a viewing axis in the orientations shown in FIGS. 51 and 52. The lobes 620 are sliadably attached such that they are able to translate towards and away from the selector 610, in a left to right motion in the orientations shown in FIGS. 51 and 52. The selector 610 includes arms 630 extending away from a central portion 640, wherein the arms 630 engage with slots 650 on the lobes 620. The slots 650 on the lobes 620 are offset from a central portion of the lobes 620 towards a periphery of the respective lobe 620.

[0237] A first end of each slot 650 is located at a first position with a first radius relative to the axis of rotation of the selector 610, and a second end of the slot 650 is located at a second position with a second radius, greater than the first radius, relative to the axis of rotation of the selector 610. As such, rotation of the selector 610 to cause the arms 630 to move from engagement with the first end of the slot 650 to engagement with the second end of the slot 650 will cause the lobes 620 to translate relatively closer to central portion 640 of the selector 610, and vice versa.

[0238] The system further comprises a limit pin 660 arranged on a lobe 620, two limit stops 670 flanking the lobes 620 and the two docking lock release paddles 383. The docking lock release paddles are described in more detail with reference to FIGS. 32 and 33. The limit stops 670 may be arranged on the base portion such that they are held still whilst the infant carrier module rotates. Rotation of the infant carrier module, with the lobes 620 positioned in an outermost or widest position, as shown in FIG. 51, causes the lobes 620 to engage with the release paddles 383 to release the docking mechanism and allow the infant carrier module to be removed from the base portion. In this arrangement, the limit pin 660 engages with the limit stop 670 and prevents rotation of the infant carrier module beyond 90°.

[0239] The selector 610 is operable by a user to position the selector is one of three positions. The first position is shown in FIG. 51, with the lobes 620 fully extended. The selector 610 may be arranged in a second position (not shown), between the arrangements shown in FIGS. 51 and 52, in which the lobes 620 are partially retracted such that the lobes 620 do not engage with the release paddles 383, but the limit pin 660 does engage with the limit stop 670. Accordingly, in the second position, rotation of the infant carrier module may be limited by the limit pin 660, but the infant carrier module may not be released by rotating the infant carrier module to a sideways facing position.

[0240] As shown in FIG. 52, the selector 610 may be arranged in a third position in which the lobes 620 are fully retracted such that the lobes 620 are spaced from the release actuators 383 and the limit pin 660 are spaced from the limit stops 670 at all orientations of the infant carrier module. Accordingly, in the third position, the infant carrier module may be freely rotated through 360° whilst remaining locked in a docked configuration.

[0241] The infant carrier module may be restricted to rearward facing only when the selector 610 is arranged in the first or second positions. The selector 610 may be arranged in the first position only when the infant carrier module is rear facing and has the carrier handle attached. The selector 610 may be arranged in the second position only when the infant carrier module is rear facing without the carrier handle attached. The selector 610 may be arranged in the third position with the infant carrier module in any orientation, without the carrier handle.
