Folding seat

Abstract

The invention discloses a folding seat, comprising a seat frame skeleton, a seat frame support, a backrest skeleton, backrest supports, and a connecting rod mechanism and an unlocking mechanism, wherein the lower part of the backrest skeleton is hinged between two backrest supports; the connecting rod mechanism comprises first and second connecting rods; the upper and lower ends of the first connecting rod are respectively hinged with the side parts of the seat frame skeleton and the seat frame support; the seat frame support is pivotally supported above the seat frame support, so that the height of the seat frame skeleton is adjustable; lower two sides of the backrest frame are provided with a cantilever; one end of the second connecting rod is hinged to the side part of the seat frame skeleton, and the other end is hinged to the end part of the cantilever; when the backrest frame is folded forward, the cantilevers at the lower two sides of the backrest frame rotate with the backrestframe to pull the seat skeleton backward and move downward; and when the backrest skeleton is folded to a horizontal state, the seat frame skeleton is moved backwards and downwards directly below thebackrest skeleton. The object of the folding seat is to enable the backrest of the seat to be completely flattened, thereby increasing the effective storage space in the vehicle.

Description

technical field [0001] The invention relates to a seat of a motor vehicle, in particular to a folding seat. Background technique [0002] The wrapping of the occupant's body and the support of the occupant's thigh by the seat are important evaluation indicators of seat comfort. For this reason, the side wings of the seat cushion of the existing motor vehicle seat protrude from the center of the cushion, and the occupant's thigh For wrapping, the side wings of the backrest protrude from the middle of the background, wrapping the upper body of the occupant, providing sufficient protection for the occupant when the vehicle is turning, and avoiding the occupant's body roll.
