Automobile seat turnover mechanism

Abstract

The invention discloses an automobile seat turnover mechanism. The automobile seat turnover mechanism comprises an angle adjuster positioned and connected onto a seat skeleton, a seat upper edge plateconnected with a rotation component of the angle adjuster, a seat lower edge plate connected with a fixed component of the angle adjuster and a coil spring hanging plate fixedly connected onto the seat lower edge plate, wherein the seat upper edge plate can rotate around the angle adjuster, an upper clamp groove is formed in the lower end portion of the seat upper edge plate, a lower clamp grooveis formed in the upper end of the seat lower edge plate, a rear limiting structure is arranged on one side edge of the upper end portion of the seat lower edge plate, and a front limiting structure is arranged on the other side edge of the upper end portion of the seat lower edge plate. The automobile seat turnover mechanism further comprises a return coil spring, wherein the return coil spring is coiled around the coil spring hanging plate, an inner clamp head of the return coil spring is hooked on the coil spring hanging plate, and an outer clamp head of the return coil spring is hooked inthe upper clamp groove and the lower clamp groove. The automobile seat turnover mechanism not only can guarantee unlocking and automatic returning functions of a backrest, but also can reduce turnoverforce of a seat, and easily performs turnover operation on the seat.

Description

technical field [0001] The invention relates to an accessory device of a vehicle body, in particular to an automobile seat folding mechanism. Background technique [0002] At present, the car seat folding mechanism is mainly based on a simple first-level limit. When the seat back is folded, the full stroke of the return coil spring works. When the seat back is folded in the latter part of the stroke, the return coil spring will generate a large force, which makes it difficult to fold the seat. see figure 1 , one end of the original return coil spring 1 is hooked on the original lower side plate 2 of the seat, and the other end is hooked on the original upper side plate 3 of the seat. In the second half, a large recovery force will be generated, which is not conducive to the operation of the weak person and affects the use. Therefore, there is a demand for improvement in the existing seat folding mechanism. [0003] CN 205890615U discloses "a front seat folding mechanism"...

AI Technical Summary

Problems solved by technology

When the seat back is folded, the full stroke of the return coil spring works. When the seat back is folded in the latter part of the stroke, the return coil spring will generate a large force, making it difficult to fold the seat.

see figure 1 , one end of the original return coil spring 1 is hooked on the original lower side plate 2 of the seat, and the other end is hooked on the original upper side plate 3 of the seat. In the second half, it will produce a large recovery force, which is not conducive to the operation of people with weak strength and affects the use
