Air Bag: Description and Operation
Driver Side Airbag
Airbag
The steering wheel airbag consists of a gas generator and an air bag. The gas generator is riveted and bolted to a metal bracket. The airbag is protected
by a plastic casing with fractural impressions which is fitted to the metal bracket. The volume of the air bag is approximately 70 liters.
The steering wheel airbag is connected between pins 10 and 11 on the control module. A special contact roller distributes test and detonation current
to the steering wheel airbag.
Steering Wheel Airbag Gas Generator
The gas generator consists of an aluminum casing divided into a central chamber and two annular chambers. The center chamber contains an electric
detonator and an explosive charge which is connected via passages to the inner annular chamber.
The inner annular chamber contains a fuel that generates a gas when it is burned, and which via passages reaches a filter in the outer annular chamber.
The filter removes particles from the gas before it passes out to the airbag.
