Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mechanical manufacturing tooling, and particularly to an automobile seat torsion spring mounting device. BACKGROUND

[0002] With the rapid development of the automobile industry, more and more automobile manufacturers have gradually eliminated the manual seat adjustment mode of automobile seats and instead use the more technologically convenient electric seat adjustment mode. This technological progress has greatly changed the comfort and operational convenience of the seat.

[0003] Electric seat adjustment includes adjusting the relative angle between the seat and the backrest by using a motor, including expanding the angle and reducing the angle. However, based on the gravity of the backrest itself, when the angle between the backrest and the seat is large, simply using a motor to drive it to recover requires a lot of driving force, and repeated driving can easily cause damage to the motor. Therefore, a torsion spring that assists in the resetting of the backrest needs to be provided between the seat and the backrest.

[0004] The torsion spring needs to be twisted to a certain degree before being fixed between the seat and the backrest, so that it always provides a force to reduce the included angle between the seat and the backrest, thereby reducing the pressure on the motor driving the backrest to reset. However, the torsion force of the torsion spring provided on the automobile seat is very large, and it cannot be twisted and assembled by hand. Therefore, an automobile seat torsion spring mounting device needs to be provided.

[0005] The information disclosed in this BACKGROUND section is only for the purpose of increasing the understanding of the background of the present application and should not be regarded as admitting that it forms the prior art that is known to those of ordinary skill in the art. SUMMARY
