What is an Airbag?

[SanColton]

An airbag is a passive safety feature in motor vehicles, designed to work in conjunction with seat belts to provide effective collision protection for occupants. Here are the specific details: 1. Function: In the event of a collision, the inflation system rapidly fills the airbag within less than a tenth of a second. The airbag expands and deploys from the steering wheel or dashboard, shielding the occupants from the impact forces of a frontal collision. 2. Concept: The airbag was first proposed by John Hetrick, who obtained a U.S. patent for an "Automobile Safety Cushion." With the establishment of vehicle safety standards in various countries, the installation rate of airbags has significantly increased. Airbags can also be classified based on their placement, including front airbags, passenger airbags, side airbags, rear side airbags, side curtain airbags, and knee airbags, offering comprehensive protection for drivers and passengers.
