Technical Field

[0001] The utility model belongs to the technical field of vehicle seats, and particularly relates to a seat that can achieve zero-gravity and flat-folding functions. Background Art

[0002] With the continuous development of the automotive industry and the continuous improvement of the degree of intelligence, consumers' requirements for the comfort of vehicle seats are also constantly increasing. For example, seats that can achieve zero-gravity adjustment, or seats that can be folded flat forward to increase the storage space in the vehicle.

[0003] Currently, the seats on vehicles have the function of separately achieving zero-gravity adjustment and the function of separately achieving the forward flat-folding of the seat. Since various structures are arranged under the seat cushion when realizing the zero-gravity adjustment of the seat, the overall height of the seat cushion is relatively high. Therefore, when the seat with the zero-gravity adjustment function is folded forward, interference is likely to occur between the backrest and the seat cushion of the seat, resulting in a relatively high seat height after it is folded forward flat, so that it cannot be completely folded forward flat. Summary of the Utility Model

[0004] The utility model intends to propose a seat that can achieve zero-gravity and flat-folding functions, and simultaneously has the functions of zero-gravity adjustment and forward flat-folding, so that the seat can not only meet the comfort requirements, but also meet the needs of different in-vehicle scenarios after being completely folded forward flat.

A zero-gravity drive component for driving the link component to achieve zero-gravity adjustment and a flat-folding drive component for the link component to achieve flat-folding adjustment are arranged between the link component and the fixed component.

[0006] Preferably, two groups of the fixed components are arranged opposite to each other left and right. Each group includes a rear fixed frame for connecting with the rear end of the link component, a front fixed frame for connecting with the front end of the link component, and a backrest fixed frame for connecting with the rotation component.

[0007] More preferably, the link component includes a zero-gravity adjustment component, a front link component, and a rear link component. The middle of the zero-gravity adjustment component is hinged on the fixed component. The lower end of the front link component is hinged on one end of the zero-gravity adjustment component, and the upper end of the front link component is hinged on the front end of the seat frame skeleton. The lower end of the rear link component is hinged on the fixed component, and the other end is hinged on the rear end of the seat frame skeleton.

[0008] Further preferably, one end of the zero-gravity driving assembly is hinged to the other end of the zero-gravity adjusting assembly, and the other end is hinged to the rear end of the fixing assembly. The flattening driving assembly is arranged between the fixing assembly and the rear link assembly.

[0009] Further preferably, the zero-gravity driving assembly adopts a motor screw rod assembly, and the flattening driving assembly adopts an angle adjuster assembly.

[0010] Further preferably, the zero-gravity adjusting assembly includes two zero-gravity adjusting links arranged oppositely left and right, and a front synchronization rod for ensuring synchronous movement of the left and right sides during zero-gravity adjustment is arranged between the two zero-gravity adjusting links; the front link assembly includes two front links arranged oppositely left and right; the rear link assembly includes two rear links arranged oppositely left and right, and a rear synchronization rod for ensuring synchronous movement of the left and right sides during flattening adjustment is arranged between the two rear links.
