Folding mechanism with clearance compensation function

Abstract

The invention discloses a folding mechanism with clearance compensation function, which comprises a lower connecting plate and a folding and overturning assembly, wherein the lower connecting plate is connected with a seat cushion framework of a seat; the folding and overturning assembly is rotatably connected with the lower connecting plate through a rotating shaft component, and the folding and overturning assembly overturns around the axis of the rotating shaft component. The folding and overturning assembly also comprises a clearance compensation plate and a clearance compensation spring, and a compensation face with locking function and compensation function is arranged on the clearance compensation plate. When a first baffle plate is completely overturned, the compensation face is engaged with a first locking face on the lower connecting plate under the action of the clearance compensation spring so as to compensate a clearance caused by production errors and abrasion and eliminate the back-and-forth swinging of a seat back. The invention fully considers the strength requirement during design, so that the folding mechanism is ensured not to break down when the seat back is pulled by a three-point seat belt, the static strength of a single folding mechanism exceeds 2300 NM and achieves the domestic leading level.

Description

technical field [0001] The invention relates to a folding mechanism, in particular to a folding mechanism applied to a folding seat, in particular to a folding mechanism with a gap compensation function. The seat can be folded forward and laid flat by using the folding mechanism. The folding mechanism has the function of gap compensation, and the folding mechanism is applied to the car seat. Torque acting on the seat back at the upper anchor point. Background technique [0002] At present, some traditional seat folding mechanisms with folding function are known. Due to manufacturing errors or continuous use of the folding mechanism, there will be gaps, which will cause the seat to shake. When some existing seat folding mechanisms are applied to car seats, Its strength also can not satisfy the intensity requirement of the relevant national standard that fixed point is on the seat on the three-point safety belt, there is potential safety hazard when the passenger rides.

[0002] At present, some traditional seat folding mechanisms with folding function are known. Due to manufacturing errors or continuous use of the folding mechanism, there will be gaps, which will cause the seat to shake. When some existing seat folding mechanisms are applied to car seats, Its strength cannot meet the strength requirements of the relevant national standards of the fixed point on the seat on the three-point safety belt, and there are potential safety hazards for passengers when riding
