The airbag was first proposed by Hetrick in August 1953 and obtained the U.S. patent for "automobile buffer safety device".
The airbag system is a passive safety protection system that works in conjunction with seat belts to provide effective anti-collision protection for the occupants. In a car collision, car airbags can reduce the rate of head injuries by 25% and the rate of facial injuries by about 80%.
In order to ensure that the airbag opens at the appropriate time, automobile manufacturers have stipulated the conditions for the detonation of the airbag. Only when these conditions are met, the airbag will explode.

Notes
1. When the car is equipped with a front passenger airbag, children must not be allowed to sit in the front seat or in this position. When placing a child seat, if the airbag in this position can be manually turned off, the airbag in this position should be turned off before the child rides. Because the explosion of the airbag will cause a certain degree of harm to children, the impact of the front passenger airbag is greater, and its explosive force is beyond the ability of children.
2. Pay attention to the airbag warning light located on the dashboard. Under normal circumstances, when the ignition switch is turned to the "ACC" or "ON" position, the warning light will come on for about 6 seconds, and then go out after self-test. If the warning light stays on, it indicates that the airbag system is faulty and should be repaired. Otherwise, the airbag may not work or may be deployed accidentally.
3. The airbag must be replaced after it explodes. When installing a new airbag, you must pay attention. The collision sensor installed inside the computer board must be replaced with the computer board, and the collision sensor installed outside the computer board must be replaced separately, otherwise It is easy to detonate; since the air bag is used with the seat belt, the seat belt tensioner of the tensioning device must also be replaced.
