Motor-driven connecting rod type cushion folding mechanism

Abstract

The invention discloses a motor-driven connecting rod type cushion folding mechanism. Two mounting brackets are symmetrically arranged on two sides of a rear transverse pipe, two connecting rod mechanisms are symmetrically arranged on two sides of a seat frame bent pipe, each connecting rod mechanism comprises four connecting rods, the rear end of the first connecting rod is hinged to the upper side of the mounting bracket, and the rear end of the second connecting rod is hinged to the lower side of the mounting bracket; and the upper end of the third connecting rod is hinged to the rear end of the seat frame bent pipe, the middle of the third connecting rod is hinged to the middle of the first connecting rod, the lower end of the third connecting rod is hinged to the front end of the second connecting rod, the upper end of the fourth connecting rod is hinged to the front end of the seat frame bent pipe, the lower end of the fourth connecting rod is hinged to the front end of the first connecting rod, and the transmission device is connected with the connecting rod mechanism. The folding mechanism is ingenious in design, can be easily folded by 90 degrees or larger than 90 degrees, increases the available space of a rear row seat to the maximum extent, solves the problem that an aisle in a vehicle is blocked by the seat, and improves the use convenience and comfort of the seat.

Description

technical field [0001] The invention relates to the technical field of automobile seats, in particular to a motor-driven link type seat cushion folding mechanism. Background technique [0002] With the development of mobile office and leisure culture, people's requirements for vehicles are no longer satisfied with transportation tools, but gradually tend to develop in the direction of mobile space for home and office. In order to realize the switching needs of people in different scenes such as meeting customers, relaxing, and resting in the car, the requirements for the functionality and changeability of the seat are put forward, and the storage seat is derived from this. [0003] The folding mechanism of the rear seat of a traditional car usually folds the backrest of the rear seat forward, so that the front of the backrest and the front of the seat cushion are closely attached and placed horizontally, thereby increasing the usable space above the seat. However, for some ...

AI Technical Summary

Problems solved by technology

However, most of the current seat cushion folding mechanisms are directly turned over at the bottom of the backrest. Affected by the backrest, the seat cushion can only be turned over a certain angle, and cannot be turned over at a large angle of 90° or greater than 90°. The space occupied by the cushion is still relatively large
