Embodiment Construction

[0014] like figure 1 and figure 2 As shown in the figure, an automatic rear-moving device for a car seat includes two airbags 4 and two cylinder blocks 3, the airbags 4 are filled with high-pressure gas, and each airbag 4 is connected to a cylinder block 3 through a high-pressure pipe 6, A communication pipe 9 is arranged between the two high-pressure pipes 6, the airbag 4 is installed in front of the vehicle body, the cylinder block 3 is installed at the front end of the adjusting rack 2 of the car seat 1, and the piston rod 7 of each cylinder block 3 is connected to the adjusting tooth. The bars 2 are fixedly connected, and each airbag 4 is provided with two collision compression rods 5, and the directions of the two collision compression rods 5 are respectively toward the front of the vehicle body and the outer side of the vehicle body.

[0015] The working principle of the device of the invention is as follows: when a fault occurs, the deformed vehicle body pushes the co...

Abstract

The invention discloses an automatic backward shifting device of a vehicle seat. The device comprises two airbags and two cylinders; high-pressure gas is inflated into the airbags; each airbag is connected with one cylinder through a high-pressure pipe; the airbags are mounted in front of a vehicle body; the cylinders are mounted at front ends of adjusting racks of the vehicle seat; piston rods of the two cylinders are fixedly connected with the adjusting racks; and each airbag is provided with a collision compression rod. The device uses the collision compression rods for extruding the airbags to force the high-pressure gas in the airbags to push the piston rods to drive the seat to backwards shift through the adjusting racks, so that automatic backward shifting of the vehicle seat is realized in vehicle failures, a larger operation space is created for rescue, the rescue work is more convenient, and the vehicle failure rescue efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of vehicle safety, in particular to an automatic rear-moving device for an automobile seat. Background technique [0002] At present, there are two main methods for protecting occupants in automobiles, airbags and automatic retractable seat belts, both of which can protect the occupants to a certain extent in the event of an accident. However, in the process of working, the direction of the occupant's body movement is forward, and the direction of movement of the body deformation is backward. The direction of movement of the two is opposite, which shortens the distance between the body and the car body. In the case of large deformation of the car body, the damage to the human body is increased. At the same time, there is a situation where the body is squeezed in the car body, it is difficult to rescue in time, and the rescue time is prolonged. In the event of a vehicle accident, the entire seat can be move...
