Automobile seat adjusting mechanism with function of automatically backwards moving once collision occurs

Abstract

The invention discloses an automobile seat adjusting mechanism with a function of automatically backwards moving once a collision occurs. The automobile seat adjusting mechanism comprises a manual control adjusting device and an automobile control sliding device, wherein the manual control adjusting mechanism is used for adjusting front and back positions of a seat in a normal state, the automobile control sliding device is fixedly connected between two manual control moving slide rails and used for connecting with an automobile seat main body, the automobile control sliding device comprises the automobile control moving slide rails, and the automobile control moving slide rails are controlled to start, lock and return by an electronic control unit (ECU) once the collision occurs and capable of sliding backwards along an extending direction of the manual control moving slide rails. According to the automobile seat adjusting mechanism, during normal usage, the front and back positions of the seat can be manually adjusted, when an automobile is collided, the automobile control sliding device can start automatically to enable the seat to move backwards, and thereby injuries caused by crashing of a driver and passengers with a steering wheel and an instrument panel can be avoided or relieved. The automobile seat adjusting mechanism is suitable for matching with main driver and co-driver seat main bodies of various vehicles so as to adjust the front and back positions of the seat.

Description

technical field [0001] The invention relates to a car seat, in particular to a car seat adjusting mechanism with the function of automatically moving backwards when a collision occurs. Background technique [0002] In existing car seats, the adjustment of the front and rear positions of the main driver's seat and the co-driver's seat generally needs to be performed manually by the driver or the passenger. [0003] The existing car seat manual control adjustment device generally includes components such as an adjustment handle 1, a manual control static slide rail 2, a manual control brake slide rail 3, a rotating plate 5, a manual control locking pin 7 and a return spring 6, and the structure is as follows: figure 1 and figure 2 shown. When adjusting the position of the seat, first pull the adjustment handle 1 upwards, and the adjustment handle 1 rotates around the fixed point to drive the rotating plate 5 to rotate upwards, and simultaneously drives the manual control lo...

AI Technical Summary

Problems solved by technology

[0004] It can be seen that when a car accident occurs, the seat cannot move backward automatically. At the moment of car collision, the driver or passenger will rush forward due to inertia, and it is easy to collide with the steering wheel and instrument panel, resulting in injury or even death to the driver or passenger.
