a folding seat

Abstract

The invention discloses a folding seat, which comprises a seat frame frame, a seat frame support, a backrest frame, a backrest support, a link mechanism and an unlocking mechanism, the lower part of the backrest frame is hinged between two backrest supports; the connecting rod The mechanism includes first and second connecting rods, the upper and lower ends of the first connecting rod are respectively hinged with the side part of the seat frame skeleton and the seat frame support, pivotally supporting the seat frame skeleton above the seat frame support, so that The height of the seat frame is adjustable; there are cantilevers on both sides of the lower part of the backrest; one end of the second connecting rod is hinged on the side of the seat frame, and the other end is hinged to the end of the cantilever; when the backrest is folded forward, its lower part The cantilevers on both sides rotate with the backrest frame, pulling the seat frame frame to move backward and downward; when the backrest frame is folded to a horizontal state, the seat frame frame moves backward and downward to directly below the backrest frame. The purpose of the present invention is to make the backrest of the seat completely flat, thereby increasing the effective storage space in the car.

Description

technical field [0001] The invention relates to a seat of a motor vehicle, in particular to a folding seat.
