[0002] At present, an automobile airbag is an important auxiliary device for the safety protection device of a seat belt. The airbag has become an essential equipment for each automobile like a seat belt, and is also an index for testing the safety of an automobile. When a traffic accident occurs to an automobile and there is a strong shock, the airbag will automatically open, thereby protecting the heads and necks of the passengers in the vehicle and minimizing the injury as much as possible.
