The invention discloses a breaking device for a seat backrest of an automobile. The breaking device comprises an air bag, an air cylinder body, a piston driver and a piston cutter. The air bag is inflated with high-pressure gas. The air bag is connected with the air cylinder body through a high-pressure pipe. The air cylinder body is installed at the position of a connecting shaft of an outer side cover of an adjusting gear case at the bottom of the seat backrest of the automobile. A screw line is machined on the inner wall of the air cylinder body. The air cylinder body is connected with the piston driver through a screw output shaft. The piston driver is connected with the piston cutter through a transmission shaft in the piston driver. The air bag is provided with collision compression rods. According to the breaking device for the seat backrest of the automobile, the collision compression rods extrude the air bag so that high-pressure gas in the air bag can be compelled to push the piston cutter to do screw movement to cut the outer edge of a connecting shaft hole of a case body. Thus, the seat backrest of the automobile can move backwards when the automobile breaks down, large operation space is created for rescuing, great convenience is provided for rescuing work, and the fault residue efficiency of the automobile is improved.
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...
