Automobile airbag shaped through reinforcing material

Abstract

The invention discloses an automobile airbag shaped through a reinforcing material. The automobile airbag comprises an airbag body and a gas generator, wherein the airbag body is communicated with the gas generator; the airbag body is made of an elastic plastic material; a reinforcing piece is arranged on the outer surface of the top end of the airbag body; the periphery of the reinforcing piece is fixedly connected with the bottom end of the airbag body through reinforcing bands; the reinforcing piece and the reinforcing bands are fixed on the surface of the airbag body in a sticking manner. According to the invention, the unfolded airbag can be shaped, and the rigidity in the airbag unfolding process is distributed more uniformly, so that the contact action area of the airbag and a passenger in the inflation unfolding process is increased, the impact of the airbag to the passenger is reduced, and a safety protection effect of the airbag directly facing a driver on the passenger is promoted. The reinforcing material further has the effect of reinforcing the whole strength of the airbag and the fact that the manufacturing process is simple, convenient and rapid is guaranteed since the reinforcing piece and the reinforcing bands are fixed in a sticking manner.

Description

technical field [0001] The invention relates to an automobile safety air bag, in particular to an automobile safety air bag shaped by reinforcing materials. Background technique [0002] The airbag system is a passive safety protection system, which is used in conjunction with seat belts to provide effective anti-collision protection for the occupants. [0003] When a collision accident occurs while the car is running, various sensors respond, and the electronic controller then works to control the start of the gas generator. After the gas generator receives the signal, it ignites the gas generating agent, generates a large amount of gas, and makes the airbag expand rapidly in a very short time, forming an elastic air cushion on the front, side or top of the driver or passenger to absorb the impact energy, thereby Effectively protect the head and chest of the human body from injury or reduce the degree of injury. [0004] When the gas generator is started, the generated ga...

Problems solved by technology

At present, some airbags shape the shape of the airbag after it is stretched by designing the volume and thickness of each part. This method has a complicated structure and is difficult to manufacture.
