Description

Technical Field

[0001] This utility model belongs to the field of automotive seat technology, and in particular relates to a folding and lifting structure for the rear seat cushion frame. Background Technology

[0002] With the increasing prevalence of cars in daily life, they have become an important means of transportation. Car seats are a crucial component, affecting both passenger comfort and safety. In traditional cars, the rear seat cushion frame is typically fixed to the vehicle body, lacking flexibility and limiting the multi-functional use of interior space. This design is particularly limiting in the face of the electric vehicle revolution. Electric vehicles, with their integrated and modular body design, are leading the future of the automotive industry. However, this trend presents new challenges to seat design, especially in optimizing space layout.

[0003] However, in the current automotive industry, only a few models feature rear seat cushion frames with a folding function, which improves seat flexibility to some extent. But with the increasing popularity of electric vehicles, this design can no longer meet consumers' growing demand for efficient space utilization. While the integrated body structure of electric vehicles is more compact and efficient in overall design, it also places stricter space constraints on seat layout. Therefore, there is a need for a rear seat cushion folding upward frame structure that meets the space requirements of the integrated body structure of electric vehicles, while also ensuring rear seat comfort, with the seat cushion facing outwards when folded up for a more aesthetically pleasing appearance.

[0016] Preferably, the left and right main support tube connecting brackets are distributed opposite to each other.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] By pulling the unlock lever, the unlocking puller located on the upper left and right sides of the adjuster is activated, unlocking the left and right sides of the adjuster. Then, by manually pulling the seat frame welding assembly, the connecting rod assembly and the adjuster connecting rod assembly are activated, causing the seat cushion frame to fold upwards by 60°. At this point, the seat cushion frame reaches its final folding position. This allows the rear seat cushion to fold upwards to meet the space requirements of the integrated electric vehicle body structure, while also satisfying the comfort and functionality of the rear seats. When the seat cushion folds upwards, the front of the seat cushion faces outwards, resulting in a more aesthetically pleasing appearance. Attached Figure Description
