How Does a Car Airbag Deploy?

[VonJayce]

Airbag deployment principle: When the sensor detects a vehicle collision, the gas generator triggers ignition to cause an explosive reaction in the airbag, generating nitrogen or releasing compressed nitrogen to fill the airbag. When the passenger comes into contact with the airbag, it absorbs the energy generated during the collision through cushioning, thereby protecting the passenger. Introduction to airbags: An airbag is a vehicle occupant restraint system consisting of an airbag cushion, flexible fabric bag, inflation module, and impact sensor. The purpose of an airbag is to provide a soft cushion and restraint for occupants during a collision event, reducing injuries between passengers and vehicle occupants.
