What Gas is in the Airbag?

[JeremiahFitz]

Airbags are inflated with nitrogen gas, which causes the airbag to expand within 0.1 seconds. Concept and working principle: The airbag contains solid sodium azide (NaN3), which rapidly decomposes upon severe impact to generate a large amount of nitrogen gas, hence the airbag is filled with nitrogen. The airbag system is a passive safety protection system that, when used in conjunction with seat belts, provides effective collision protection for occupants. In the event of a car collision, airbags can reduce head injuries by 25% and facial injuries by approximately 80%. Airbag components: Mainly consists of airbag sensors, collision airbags, and electronic control devices; the driver-side collision airbag is installed in the steering wheel; the passenger-side collision airbag is usually mounted on the dashboard; airbag sensors are installed on the left, right, and center of the cabin partition; the central airbag sensor and airbag system are integrated with the electronic control device.
