Airbag igniter 2, front passenger side N132
The airbag control unit defines the time interval between the deployment of airbag igniter 1, front passenger
side N131 and airbag igniter 2, front passenger side N132 according to the type and severity of the accident.
The task of the second gas generator is to inflate the airbag to its full size.
The second gas generator has exactly the same function as the first gas generator.
Airbag igniter 1, front passenger side N131
If igniter I is electrically activated by the airbag control unit J234, it ignites priming charge I. Under the
resulting pressure, the flame passes through the rupture disc and ignites propellant charge I.
On account of the hollow propellant tabs, the complete propellant charge ignites more quickly.
The metal filter cools and treats the developing gas before it flows through the outlets to the airbag.
The task of the first gas generator is to inflate the airbag.
