Safety Component - Gas Generator
The high-pressure gas required for the car's airbag system is generated by a gas generator. When the vehicle collides during driving, the generator’s acceleration sensor detects the peak acceleration signal and the duration of the impact—essentially sensing the magnitude of the collision energy. Based on this collision energy level, the sensor automatically determines whether to deploy the airbag. If the collision energy reaches the predetermined activation threshold, the sensor sends an opening signal, triggering the release of a striker pin. This pin sequentially ignites the primer cap and then sets off the detonator charge within the initiator assembly. The resulting combustion instantly activates the main propellant charge, producing a burst of high-pressure gas. Finally, the gas is expelled through a deflector plate and filtered mesh, inflating the airbag.
