Abstract

The car seat back breaker includes an airbag, a cylinder block, a piston driver and a piston cutter. The airbag is filled with high-pressure gas, and the airbag is connected to the cylinder block through a high-pressure tube. The cylinder block is installed on the adjustment gear at the bottom of the backrest of the car seat. At the connection shaft of the outer cover of the box, the inner wall of the cylinder is processed with a helix. The cylinder body is connected with the piston driver through the helical output shaft, and the piston driver is connected with the piston cutter through the built-in transmission shaft. The invention squeezes the airbag by colliding with the compression rod, forcing the high-pressure gas in the airbag to push the piston cutter to do a spiral movement, and cut off the outer edge of the connecting shaft hole of the box, thereby realizing the backward movement of the backrest of the car seat when the vehicle breaks down, and providing assistance for rescue. A large operating space is created, which greatly facilitates the rescue work and improves the efficiency of vehicle failure rescue.

Description

technical field [0001] The invention relates to the technical field of vehicle safety, in particular to an automobile seat back breaker. Background technique [0002] In many vehicle accidents, there is a problem that the injured are difficult to be rescued. This is mainly because a fixed narrow space is formed between the deformed car body and the car seat in the accident. Want to rescue the injured, the method that adopts more at present is to cut the car body with a demolition device, and rescues the personnel. This method is time-consuming and expensive, and easily causes secondary injuries to personnel. If the seat can be separated from the vehicle body or the seat can be separated from the backrest, it is easy to rescue people. It is more difficult to separate the seat from the vehicle body, but relatively less difficult to separate the seat from the seat back. The structure of the car seat is: the backrest is fixedly connected to the adjusting gear box, the adjust...
