Description

[0001] AN ADJUSTABLE SAFETY CAR SEAT

[0002] Field of the Invention

[0003] The present invention relates to an adjustable safety car seat. In particular, the invention is concerned with an improved child’s safety car seat which is integrated into a car’s main seat and is capable of adjusting to the child’s requirements.

[0004] Background

[0005] Children’s safety car seats are used to ensure the safe transportation and protection of young passengers in vehicles. According to UK government guidelines, children are advised to use a safety car seat until they reach the age of 12 or a height of 135 centimetres, whichever occurs first. These guidelines are structured to provide appropriate safety measures for transporting children in vehicles throughout the different stages of a child's growth and development.

[0006] There is a variety of children’s safety car seats available which reflects the evolving needs of children as they mature. Infants, from birth to 18 months, typically require rear-facing infant seats to provide optimal support for their delicate neck and spine. As children grow older, forward-facing seats become suitable from around 9 months to 4 years of age, offering enhanced protection in the event of a frontal collision. Booster seats cater to children aged 4 to 6 years, ensuring proper seat belt placement and improved comfort during travel. For older children, booster cushions are designed to elevate seating positions and maintain safety forthose aged 6 to 12 years.

[0007] As children progress through these developmental stages, the need for new safety car seats at each milestone contributes significantly to the environmental impact. According to the Local Government Association, approximately 2000 tonnes of safety car seats are discarded annually in the UK, presenting both a waste management challenge and a financial burden for families needing to purchase replacements. Reselling of safety car seats is also discouraged due to the inability to verify if the safety of the seat has been compromised in any way. Once a safety car seat has been used, there is no reliable method to ensure it has not been involved in an accident or mishandled, both of which can significantly reduce its effectiveness in protecting a child in subsequent use. This lack of assurance poses a risk to potential buyers, as they cannot be certain of the seat's history or condition, thereby potentially jeopardising the safety of the child who would use it. Consequently, experts recommend against purchasing or selling used safety car seats as a measure to prioritise child safety.

[0008] Furthermore, changing vehicles or carpooling arrangements necessitates additional seats, which increases the number of discarded seats ending up in landfills once they are no longer required. While some families opt to transfer safety car seats between vehicles, this practice can be cumbersome and potentially compromise safety if installation procedures are not followed correctly.

[0009] In addition to the environmental impact, there are several other issues and challenges associated with child safety car seats. Not all safety car seats fit well in all vehicles. Factors like seat shape, belt length, and the presence of airbags can affect compatibility, influencing the options available to parents and caregivers. This limitation may force them to choose seats that are not necessarily ideal for their vehicle, potentially compromising safety and comfort for the child. Furthermore, the standardisation of children’s safety car seats limits the ability to address individual safety requirements. Generic specifications may not always accommodate specific needs, such as medical conditions like cerebral palsy, which require customised solutions for optimal safety and comfort. The lack of personalised options in off-the-shelf safety car seats underscores the importance of considering diverse safety needs and advocating for advancements in adaptive seating technologies.

[0010] Various prior art documents have discussed the need for an adjustable safety car seat.

[0011] KR 20140104656 A describes a vehicle seat structure that incorporates a built-in child seat. The document describes mechanisms for converting a standard vehicle seat into a child seat configuration, addressing convenience and safety concerns associated with integrating child restraint systems directly into vehicle seats.

[0012] KR 101362390 B1 relates to a child safety seat apparatus for vehicles. It discusses improvements in the securement and adjustability of child seats, focusing on enhancing occupant protection and ease of installation within a vehicle’s main seat structure.

[0013] US 5,553,918 A describes a convertible vehicle seat assembly that can be reconfigured between a standard adult seat and a child safety seat. The patent application emphasises mechanisms for stowing and deploying child seat components, aiming to simplify conversion and maintain seat comfort for adult passengers.

[0014] US 10,696,194 B1 pertains to a vehicle seat with an integrated child seat module. The document details structural features and mechanisms that allow the child seat to be concealed or revealed as needed, with a focus on maintaining the functionality of the main vehicle seat.

[0015] US 2004 / 032154 A1 describes a vehicle seat assembly with a built-in child seat. The patent discusses various configurations for accommodating both child and adult occupants, highlighting safety features and ease of use in transitioning between seat modes.

[0016] In conclusion, while children’s safety car seats are indispensable for safeguarding young passengers during travel, there remains a need for sustainable practices in seat disposal and advancements in customisable safety solutions.

[0062] Detailed Description of the Invention

[0063] The features and aspects of the embodiment are described in detail below with reference to the drawings.

[0064] FIG. 1 illustrates a first embodiment of an adjustable safety car seat 100 wherein the adjustable safety car seat 100 is integrated into a main vehicle seat 200. The seat is suitable, when not deployed as a child seat, to accommodate an adult passenger. When the adjustable safety car seat 100 is not in use, a moveable back panel 110 is situated within a backrest frame 210 of the main vehicle seat 200 and the front face 111 of the moveable back panel 110 is visible. A moveable seat panel 120 is situated within a seat structure 220 of the main vehicle seat 200 with the first face 121 visible. It will be appreciated that in use, the elements such as the moveable back panel 110, backrest frame 210, the moveable seat panel 120, the moveable side panels 112, which support the child or adult passenger would be covered with padding typically used in vehicles, for the comfort of the passenger. The padding is moveable with movement of an element of the car seat and also serves as padding for an adult user, preferably being aesthetically integrated with the rest of the upholstery of the car.

[0065] When the adjustable safety car seat is not in use and integrated into the main vehicle seat 200, the back panel is in the nested position. The cover of the moveable back panel 110 is overlaid with the backrest cover of the backrest frame 210 in a way that makes the moveable back panel 110 and back panel cover appear to fuse into the backrest cover of the backrest frame 210 creating a main surface of the backrest frame when the adjustable safety seat 100 is not in use. The moveable seat panel 120 and seat structure 220 typically both comprise padding (not shown) for comfort of passengers. The moveable seat panel 120 can comprise a seat panel cover (not shown). The seat structure 220 comprises a seat structure cover. The moveable seat panel 120 comprises side-retainers 122, which act to restrain a user from lateral movementwhen the car is being driven. The seat structure 220 of the main vehicle seat 200 comprises side seat bolsters 222. When not in use and the seat panel is in the retracted position, the side-retainers 122 of the moveable seat panel 120 are overlaid on and optionally rest on the side seat bolsters 222 of the seat structure 220. This allows the moveable seat panel 120 to appearfused to the seat structure 220 creating a main surface of the seat structure when the adjustable safety car seat 100 is not in use. The seat panel cover (not shown) also appears to fuse with the seat structure cover, furthering the illusion that the moveable seat panel is fused with the seat structure 220. Alternatively the moveable back panel 110 and moveable seat panel 120 may be located behind the back panel cover and the cover of the seat structure 220 of the main vehicle seat 200. The covers may be zipped down and pulled away from the main structure to reveal the adjustable safety car seat 100 which can then be manoeuvred into the required position. The moveable back panel 110 and the moveable seat panel 120 is comprised of sheet metal, but it can be appreciated that other suitable materials may be used in order to form the panels of the adjustable safety car seat 100.

[0066] FIG. 2 is a perspective view of FIG. 1 the adjustable safety car seat 100 in use, the moveable seat panel 120 having been raised out of the main vehicle seat 200 in the extended position. The adjustable safety car seat 100 comprises the moveable back panel 110 and the moveable seat panel 120. The side-retainers 122 are padded and cushioned for the comfort of the child. The moveable back panel 110 comprises a moveable side panel 112 (see Figures 4). The moveable side panel 112 can operate an adjustable arm rest (not shown in Fig. 2) and an adjustable headrest (not shown). The arm rest may take the form of a padded flankwhich forms a protective barrier for younger children, or alternatively the arm rest may be adjusted to support the arm of an older child. The headrest may be lowered or raised to suit the height of the child. Furthermore the headrest may comprise adjustable headrest side panels (not shownjwhich can be raised into an upright position from a flat orientation along with the headrest. The headrest side panels may be extended or retracted depending on the requirements of the child.

[0067] FIGs 3 A-B show front perspectives of the raising and lowering of the moveable back panel 110 of the adjustable safety car seat in FIG. 1 . FIG. 3 A shows the moveable back panel 110 in the nested position. FIG. 3 B shows the moveable back panel 110 in a lowered position.

[0068] FIGs 4 A-C show front perspectives of the raising and lowering, respectively, of the moveable side panels 112 of the adjustable safety car seat 100 in FIG. 1 . The moveable side panel 112 comprise of a front face 114 and a back face 116. The moveable side panel 112 is hingeably mounted to the moveable back panel 110 along a joining edge 113. The joining edge 113 comprises a hinge, as known in the art, although it can be appreciated that other types of moveable joints may be used to achieve the same function. The joining edge 113 allows the moveable side panel 112 to be moved between a substantially parallel position (the stowed position) 115 (see Figure 4A) with the moveable back panel 110 to an angled retaining position (the deployed position) 117 with the moveable back panel 110 in which the moveable side panel 122 acts, in use, to prevent lateral movement of the user. The moveable side panels 112 can pivot between the stowed position and the deployed positon and can be stopped and held, at any intermediate position throughout the range of movement between the two positions, via an electrically driven hinge joint 119. It can be appreciated that movement of the hinge joint 119 may also be hydraulically and / or pneumatically driven. Preferably, the hinge joint is driven by an actuator.

[0069] FIGs 5 A-B show side perspectives of the adjustment of height and depth of the moveable back panel of the adjustable safety car seat in FIG. 1 . A strut 510 is attached to a pivot joint 512 via an axle 514 located on the forward-facing surface of the backrest frame 210. The opposite end of the strut (not shown) to the pivot joint 512 is attached to the back face of the moveable back panel 110. Coaxial rotation of the struts 510 via the axle 514 of the pivot joint 512 acts therefore to move the moveable back panel from either the nested position 515 to the raised position 517, or vice versa. The struts 510 are able to position the moveable back panel 110 to various heights within its range depending on the requirements of the child.

[0070] FIGs 6 A-B show side perspectives of the raising and lowering, respectively, of the moveable seat panel of the adjustable safety car seat in FIG. 1 . The moveable seat panel 120 is attached to a scissor lift mechanism 610 situated beneath the moveable seat panel 120 and within the seat structure 220 of the main vehicle seat 200. The moveable seat panel 120 is attached to the scissor lift mechanism 610 via a platform (not shown). The scissor lift mechanism 610 can raise and lower the moveable seat panel 120. The scissor lift mechanism 610 can be electrically and / or pneumatically and / or hydraulically driven. The scissor lift mechanism 610 is capable of positioning the moveable seat panel 120 to various heights within its range depending on the requirements of the child. FIG. 6A shows the moveable seat panel 120 in the extended position 615 and FIG. 6B shows the moveable seat panel in the retracted position 617.

[0071] The moveable seat panel 120 and the moveable back panel 110 can thus be independently adjusted to suit the requirements of the child.

[0072] FIG. 7 illustrates a second embodiment of an adjustable safety car seat wherein the adjustable safety car seat is raised out of the main vehicle seat. The second embodiment shows an alternative arm rest 720 wherein the arm rest is situated within the padding of the moveable back panel 110. When required, the armrest 720 is lowered down into position. The moveable back panel 110 further comprises an attachment 712 whereby the headrest 710a of the main of the vehicle seat 200 can be fitted in a different orientation to that shown as 710a to function as the headrest 710b of the adjustable safety car seat 100.

[0073] In optional embodiments, not illustrated, a side retainer 122 is mounted for pivoting along the joining edge with the moveable seat panel 120 to allow increased safety in limiting lateral movement of a user.
