Description

Technical Field

[0001] This utility model relates to the field of headrest folding technology, and in particular to a foldable and storeable car seat headrest support structure. Background Technology

[0002] As a core tool for modern travel, the design of the car's interior seats has always been a key element in enhancing the driving and riding experience. Among the many components of a car seat, the headrest plays an important role in ensuring comfort and safety. Traditional car seat headrests are mostly fixed or only have simple up-and-down adjustment functions, which exposes a series of limitations in actual use. From the perspective of space utilization, as consumers' demand for the multi-functionality of cars increases, scenarios such as flexible transformation of the interior space are becoming more and more common, such as folding down the rear seats to expand cargo space. However, non-foldable headrests often occupy extra space during the seat folding process, causing the seats to not be able to fully conform, which greatly limits the effective expansion of the interior space and makes it difficult to meet the diverse space utilization needs of users.

[0003] In terms of driving visibility, headrests, especially rear seat headrests, can obstruct the driver's view to some extent when reversing or when observing the situation behind the vehicle. This affects the driver's clear judgment of the environment behind the vehicle and increases potential driving safety risks. In particular, in narrow spaces or complex road conditions, obstructed rear visibility may prevent the driver from noticing obstacles or other vehicles and pedestrians in time, which may lead to collisions and increase the danger. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a foldable and retractable car seat headrest support structure, aiming to improve the problem that traditional headrests in the prior art cannot be folded.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a foldable and retractable car seat headrest support structure, comprising a seat, wherein each seat is equipped with a headrest rod, and a locking leaf is fixedly connected to adjacent sides of multiple headrest rods. A rotating center rod is fixedly connected between adjacent lower ends of multiple locking leaf rods. Multiple limiting posts are fixedly installed in the middle of the rotating center rod. Locking plates are rotatably connected to the left and right sides of the outer wall of the rotating center rod. Springs are installed on the outer wall of the rotating center rod between multiple locking plates and limiting posts. Connecting rods are fixedly installed between adjacent locking plates. A headrest mechanism is installed on the top of the seat, and the headrest mechanism is used for flat support of the head.

[0006] As a further description of the above technical solution:

[0007] The headrest mechanism includes a back cover, with multiple pad blocks 1 fixedly installed on the inner wall of the back cover. A spring 1 is fixedly installed at the front end of each of the multiple pad blocks 1, and a pad block 2 is fixedly installed at the front end of each of the multiple spring blocks 1. A front cover is fixedly installed on the front side of the multiple pad blocks 2. A vent hole is provided at the front end of the front cover. Buckles are provided on both the left and right sides of the front cover. Slots are provided on both the left and right sides of the back cover.
