Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of automobile seat, specifically relates to a foldable and adjustable automobile rear seat. BACKGROUND

[0002] The aforementioned foldable and adjustable refers to the front and rear adjustment of the automobile rear seat in the unfolded state through the slide rail, which has the advantages of improving the riding comfort, the rider can adjust the seat position according to the needs, and obtain a more comfortable leg position, which is particularly important for long-distance and long-time riding; flexible space allocation, the front and rear adjustment function can flexibly allocate the vehicle space according to the needs of the rider's luggage, and improve the practicability; convenient access, adjusting the position of the rear seat can provide convenience for the rider to get in and out of the vehicle, especially for children or the disabled; adapt to different body types, the front and rear adjustment can adapt to the needs of riders of different heights and / or body types, and ensure that a suitable sitting posture is obtained; enhance the carrying capacity, the trunk space can be expanded by adjusting the rear seat to place large items; improve safety, a suitable seat position helps the rider to use the safety belt and improve safety; improve the riding experience, the rider can adjust the seat position according to his own preference to improve the overall riding experience; adapt to multiple purposes, the front and rear adjustment can make the vehicle adapt to different scenes, such as family travel, business reception or cargo carrying needs, etc.

[0003] The aforementioned foldable and storable refers to the storage of the automobile rear seat in the folded state in the trunk, which has the advantages of maximizing the carrying space, folding and storing in the trunk for placing large items; flexible space utilization, according to the needs of carrying people or carrying things, the layout of the vehicle space can be flexibly adjusted; convenient cleaning; improve the practicability, when the rear seat is not needed, more space can be left for the trunk; improve the convenience of carrying, after storing the seat, the trunk opening is larger, which is convenient for placing large items, etc.

[0004] In the disclosed Chinese patent documents, there are some technical information about folding and storing the automobile rear seat in the trunk, typically as CN222473978U recommends "a convenient folding and storing automobile seat", through the reading of the patent specification, especially the paragraphs 0038 to 0039 of the specification, it can be known that: in normal use, i.e. in the unfolded state, the angle between the chair back and the chair seat is adjusted to the extent suitable for sitting by the angle adjuster; when folding, the soft cable driving member is pulled manually to unlock the ground lock on the floor of the trunk and the angle adjuster, so that the chair back is folded to the chair seat, and then turned to the storage groove in the trunk.

[0005] The CN222473978U can realize the technical effects described in paragraphs 0014 to 0016 of the specification, but still has some drawbacks: as with vehicles such as two-door cars, MPVs, SUVs and the like seen in the market so far, the rear seats can be folded and stored in the trunk by turning over, but in the unfolded and seated state, they cannot realize the many advantages of the applicant mentioned above, i.e. the front and rear adjustment by the slide rail. The reason why the "bear's paws" and "shark fin" cannot be both is that the applicant believes that in addition to the main bias in technical design, it is also affected by many surface phenomena. In terms of technical design bias, the industry generally believes that the front and rear sliding adjustment function of the car seat in the use state is guaranteed by a pair of parallel slide rails, which include a static slide rail and a dynamic slide rail that forms a sliding pair with the static slide rail, and the static slide rail is fixed immovably on the car floor, so that the car seat that needs to be folded and turned over into the trunk cannot meet the front and rear position adjustment requirement in the unfolded state of the occupant. The rear seat should focus more on comfort and space utilization rather than flexibility, and the slide rail function does not meet this design concept. Therefore, it is believed that only one of the two can be chosen, and in terms of the influence of many surface phenomena, one is that it is believed to be limited by space, because the design of the storage cavity aims to maximize the trunk space, and the slide rail will occupy more space; two is that the slide rail will increase the complexity of the seat structure; three is that the occupancy rate of the rear seat is relatively low.

[0006] The applicant believes that it is against the humanized concept to sacrifice the front and rear adjustment function of the rear seat for the expansion of the loading space by folding and storing. In addition, since the action of the CN222473978U in the process of folding and storing in the storage groove of the trunk is completed by manual operation, on the one hand, the operation is relatively laborious, on the other hand, there is a risk of impact, because impact and collision will inevitably occur in the process of being introduced into the storage groove, and on the other hand, there is a risk of safety, because if the seat is accidentally dropped during the turning process, the destructive damage to the seat is self-evident.
