Description

Child Car Seat System and Child Transportation System
Field of the Disclosure
The present disclosure relates generally to a child car seat system and child transportation system and finds particular, although not exclusive, utility in providing a child car seat system and child transportation system that are adaptable to the needs of a child as the child grows.
Background
In some countries, it is a legal requirement for babies, infants and children under a certain age and/or height to be provided with a supplemental car seat when travelling in a vehicle. Such car seats typically improve the child's safety when travelling in a vehicle, particularly in a collision scenario, when compared to the use of a typical seat belt alone. The shape, size and arrangement of the car seat is typically dependent on the child's age and/or height. A child may be required to use a so-called baby car seat from birth until approximately 1 year old, a so-called toddler car seat from approximately 1 year old to approximately 4 years old, and a so-called booster seat from approximately 4 years old until the child no longer requires the use of a car seat.
Furthermore, parents and guardians of children typically make use of a perambulator, typically and hereinafter called a pram, or a stroller to transport a child. A pram may be used to transport babies and relatively young infants, and may provide a relatively horizontal surface for the baby or infant to be transported upon in a flat lying position. A stroller may be used to transport relatively older infants, and may provide a seat arrangement for the infant to be transported in a sitting position.
However, babies and infants grow quickly and may outgrow conventional car seats, prams and strollers within a year or two years. Therefore, a parent or guardian must typically provide several car seats, prams and/or strollers for their child.
Aspects of the present disclosure seek to provide a car seat system that can be used as a child grows from infant to a toddler and older, typically up to 6 years old. The invention also seeks to provide a versatile arrangement in which components of the car seat system can be used in combination as part of an adaptable stroller and pram system
Summary
According to a first aspect of the present disclosure, there is provided a child car seat system comprising: a docking module configured to be securable to a vehicle seat; and an infant carrier module configured to receive an infant therein and arranged to be releasably docked with the docking module, the infant carrier module comprising a seat portion attached to a backrest portion via a locking hinge having two locking positions such that the infant carrier module is configurable in: an upright position in which the seat portion and the backrest portion are relatively inclined at a first angle; and a lie flat position in which the seat portion and the backrest portion are relatively inclined at a second angle, greater than the first angle.
A key advantage of the child car seat system is that the infant carrier module may be used in the lie flat position to transport an infant in a lying orientation, whilst the infant carrier module may be used in the upright position to transport an infant in an upright or sitting orientation.
Therefore, the car seat system may be usable with children of various ages and heights. Furthermore, the infant carrier module may be undocked from the docking module and may conveniently be used to carry or transport an infant. Additionally, the child car seat system may be sustainable. In particular, the child car seat system may be adaptable to the needs of a growing child without needing to provide additional components, nor dispose of components as the child grows.
The system may be configured such that the infant carrier module is adjustable within the docking module. In this regard, adjustable may mean that the seat portion and the backrest portion are relatively inclinable. Additionally, or alternatively, adjustable may mean that a headrest portion of the infant carrier module is adjustable in position relative to the backrest portion and/or the docking module. Additionally, or alternatively, adjustable may mean that In this way, the infant carrier module may be adjustable within the docking module, in particular as the child grows and becomes larger. Accordingly, there is no need to provide additional components to continue use of the system with the growing child. Additionally, there is no need to dispose of components as the child grows, thereby providing a sustainable system.
A child car seat system may be a system configured and intended to be secured to a vehicle and allow for a child to be seated thereon. A child car seat system may modify a typical vehicle seat, which are designed for use by adults, to improve the suitability of the vehicle seat for use with a child.
The docking module being securable to a vehicle seat may mean that the docking module is attachable, releasably or non-releasably, to the vehicle seat or the vehicle such that the docking module rests upon the vehicle seat.
The infant carrier module being releasably docked with the docking module may mean that the infant carrier module may be selectively seated upon and/or secured to, the docking module such that relative movement between the docking module and the infant carrier module whilst docked thereon is at least partially prevented, prohibited, reduced or inhibited.
The seat portion may be a portion of the child car seat system upon which an infant's bottom and legs may be supported. The backrest portion may be a portion of the child car seat system upon which the infant's back, arms and head may be supported. The backrest may or may not include a headrest, as discussed herein.
A locking hinge having two locking positions may be any form of rotatable attachment means that allow for the two connected components to relatively rotate, whilst also being securable in at least two relative inclinations.
The first angle may be any angle that provides a conventional sitting arrangement. For example, the first angle may be in the range of 800 to 135°. The second angle may be any angle that provides a conventional lying arrangement. For example, the second angle may be in the range of 1350 to 1800. Other angles and ranges are envisaged.
The infant carrier module may be configured to be docked in the docking module only when configured in the upright position. In this way, an infant may be positioned in a seated arrangement when being transported in a vehicle, which may improve safety. Alternatively, the infant carrier module may be configured to be docked in the docking module when configured in either the upright position or the lie flat position.
The infant carrier module may be releasably securable in the upright position and the lie flat position. Additional and/or intermediate positions are envisaged. The locking hinge may comprise suitable locking positions, as required. In this way, the infant carrier module may be arranged at an inclination that is comfortable for an infant. The locking hinge may comprise three, four, five, six or any other number of locking positions, to provide a user with greater flexibility in selecting a suitable inclination angle. In particular, the locking hinge may have four locking positions, with the two locking positions described above in relation to the first aspect of the invention being the relatively most extreme angled positions and the further two locking positions being intermediate positions.
The infant carrier module may further comprise a releasable locking mechanism configured to selectively secure the infant carrier module in the upright position or the lie flat position.
The releasable locking mechanism may include an actuator operable to release the locking mechanism and allow the relative inclination of the seat portion and the backrest portion to be adjusted. The actuator may be incorporated into a seat belt guide which may be positioned on a rear of the backrest portion.
The infant carrier module may further comprise a cushion. The cushion may be slidably attached to the backrest portion. The cushion may be configured to translate relative to the backrest portion as the infant carrier module is reconfigured between the upright position and the lie flat position. The seat portion may comprise a seat cushion. The seat cushion may be arranged adjacent to the cushion attached to the backrest portion in all orientations and arrangements of the backrest portion. In this way, a continuous cushioned surface may be provided for the infant.
The infant carrier module may include a harness configured to selectively secure an infant in the infant carrier module. The harness may be stowable within the child car seat system or removable from the child car seat system when the harness is not in use. In this way, the child car seat system may be arranged for use with an older child, with whom the harness may not be usable. The harness may be stowed or removed and a seatbelt provided in the vehicle may be used to secure the older child. The harness may be a 5-point harness.
The infant carrier module may comprise a detachable carrier handle. The carrier handle may be used to carry the infant carrier module, and an infant secured therein, when the infant carrier module is not docked in the docking module. The carrier handle may be configured to be securable to the seat portion and/or the backrest portion at a plurality of angles relative to the seat portion. The carrier handle may comprise an actuator, such as a button or pair of buttons adjacent to the carrier handle hinge points, that a user may actuate to release and reposition the carrier handle. A total of two, three, four, or any other number of positions may be provided. The carrier handle may be detachable by way of a locking clip and release lever. The locking clip may be slid from a secure to a release position, wherein the release lever may be opened, such as through 900, to release the carrier handle. The carrier handle may then be removed from the infant carrier module.
The docking module may comprise a base portion and a shell portion rotatably attached to the base portion. The infant carrier module may be configured to be releasably docked to the shell portion. In this way, the infant carrier module may be rotatable relative to the base portion and therefore rotatable relative to a vehicle seat to which the base portion may be attached. Accordingly, an infant may be positioned facing forwards, backwards, or there between. The infant may be positioned facing forwards or backwards for travel, and may be moved to a sideways facing position to improve ease of placing or removing the infant from the vehicle. The base portion may comprise ISOFIX connectors. The ISOFIX connectors may releasably yet robustly connect the base portion to the vehicle.
The docking module may comprise a forward detent configured to secure the shell portion relative to the base portion in a first rotational position. The docking module may comprise a rearward detent configured to secure the shell portion relative to the base portion in a second rotational position. The second rotational position may be approximately 1800 rotated from the first rotational position. The docking module may further comprise a sideways detent configured to secure the shell portion relative to the base portion in a third rotational position. The third rotational position may be approximately 900 rotated from the first rotational position. Other rotational positions are envisaged. A plurality of sideways detents may be provided, at regular or irregular rotational intervals.
The docking module may further comprise a detent release mechanism configured to release the, or each, detent. The detent release mechanism may comprise a button, lever or other actuator operable by a user to release the, or each, detent. The detent release mechanism may comprise a plurality of such actuators, wherein any of the actuators may be actuated to release the, or each, detent. An actuator may be positioned on two or more sides of the child car seat system such that an actuator may be accessible from multiple sides. Accordingly, the actuator may be accessible to a user stood outside of the vehicle when the child car seat is arranged behind either the driver's seat or the front passenger's seat.
The child car seat system may further comprise a docking lock mechanism configured to prevent undocking of the infant carrier module from the docking module when the shell portion is secured in the first rotational position or the second rotational position. In this way, the infant carrier module may not be undocked when arranged in the first and/or second rotational positions. The first and second rotational positions may relate to forward and backward facing positions, in use. Accordingly, the docking lock mechanism may provide an additional layer of attachment security between the infant carrier module and the docking module when the child car seat system is configured in an arrangement typically used whilst travelling in a vehicle. The infant carrier module may only be undocked from the docking module when the infant carrier module is rotated to an intermediate rotational position, such as a position facing sideways to the direction of travel. The docking lock mechanism may provide additional strength and security that is particularly important in a vehicular collision or other such scenario.
The docking lock mechanism may be configured to automatically release when the shell portion is arranged between the first rotational position and the second rotational position. In this way, a user may simply unlock the docking lock mechanism by rotating the infant carrier module from a locked position, which would typically occur when a parent is removing an infant from a vehicle. Alternatively, the docking lock mechanism may comprise a release actuator that a user may actuate to release the docking lock mechanism.
The child car seat system may further comprise a secondary safety lock configured to releasably secure the infant carrier module to the shell portion when the infant carrier module is configured in the upright arrangement. The secondary safety lock may be operational at all rotational positions of the shell portion relative to the base portion. The infant carrier module will typically be arranged in the upright arrangement when a vehicle is in motion. Accordingly, the secondary safety lock may provide an additional point of attachment and securement between the infant carrier module and the docking module, which is particularly important when the vehicle is in motion. Failure of a detent or the docking lock mechanism may be remedied by providing the secondary safety lock. In this way, the safety of an infant travelling in the child car seat system is improved.
The shell portion may be attached to the base portion via a reclining attachment mechanism configured to allow the shell portion to recline in a translational and/or rotational manner relative to the base portion when the shell portion is arranged in the first rotational position.
In this way, an infant may be reclined for comfort. The reclining attachment mechanism may comprise a protrusion translatable within a slot, wherein the shell portion may rotate about the protrusion. Other attachment mechanisms are envisaged.
The docking module may include a guide configured to urge the infant carrier module into a docking position. In this way, the infant carrier module may be positioned in the correct position for docking by engaging the infant carrier module with the guide. The guide may comprise a protrusion on one component and a corresponding slot or hole on another component. The guide may comprise any number of such protrusions and slots or holes, such as one, two, three, four or five.
The child car seat system may further comprise a headrest. The headrest may be attached to the backrest portion of the infant carrier module. Additionally, or alternatively, the headrest may be attachable to the docking module. In this way, the headrest may be positioned to provide the optimal comfort and/or safety for the infant. Additionally, the headrest may be moved further from the seat portion as the infant grows.
The headrest may be slidably attached to the backrest portion. The docking module may comprise a headrest slot. With the infant carrier module docked in the docking module, the headrest may be slidable away from the backrest portion and into the headrest slot. The headrest may comprise a protrusion configured to engage with the headrest slot. In this way, the headrest may be arranged in a position that is comfortable and safe for the infant, which is dependent on the size of the infant. Furthermore, the headrest may be moved as the infant grows. The headrest may be adjustable between a plurality of positions. In this way, the height of the headrest is adjustable dependent on the size of the infant. Preferably, the headrest is adjustable between at least three positions. The headrest may be lockable in the at least three positions. The headrest may be slidably moveable between the at least three positions.
The child car seat system may further comprise a support leg. The support leg may be rotatably attached to the docking module. The support leg may be rotatable between an extended position in which the support leg extends away from the docking module, and a stowed position in which the support leg lies adjacent to the docking module along a length of the support leg. In this way, the support leg may be extended and arranged to rest on a floor of the vehicle, or may be stowed away. The support leg may be extended when transporting a relatively young infant in a rearward facing position. The support leg may be stowed when transporting a relatively older infant in a forward facing position.

Detailed Description
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.
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.
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.
The general descriptive terms "child car seat" and "stroller" 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. A "stroller" is also commonly referred to as a pram (a shortened form of "perambulator"), buggy, pushchair or carriage.
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.
In the figures, the docking module 2 is shown in combination with the docked infant carrier module 3 in figures 7 to 12 and 15. The infant carrier module 3 is shown on its own in figures 1 to 6 and 14. The docking module alone is shown in figure 13.
Referring to figure 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 figures 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 figures 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 figures 9 and 11 the latch hooks Son the docking module back rest 2a are shown engaged (and therefore out of view).
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.
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 figure 12. Wien in infant seat mode there is a harness system 30 provided on the infant carrier module (see figure 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.
The infant carrier module 3, as shown in figure 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 figure 3) and a relatively upright position (shown in figure 5). An intermediate position is shown in figure 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.
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 Figure 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.
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.
The car seat system can be used in combination with a stroller/pram system to provide further versatility. The stroller/pram system is shown in figures 16 and 17. In figure 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.
The stroller mode configuration is shown in figure 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 figures 16 and 17.
Figure 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 Figures 1 to 17 may also be incorporated into this child car seat system and are not discussed again for brevity.
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 Figures 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.
The infant carrier module 200 also includes a headrest 240, as illustrated in Figures 24A- 240, 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 Figure 24A, a second headrest position, shown in Figure 24B, and a third headrest position, shown in Figure 240. 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.
An integral cushion 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.
The carrier handle 250 can be removed from the infant carrier module 200, as illustrated in Figure 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.
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.
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 Figures 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.

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.
Each of the sideways connecting frame members, shown as the horizontal members in Figure 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.
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 Figure 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.
The infant carrier module 200 shown in Figures 18 to 20 may be attached to the wheeled frame to form a pram or a stroller, 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.
