Airbag, driver's side


In the airbag unit on the driver's side there is a gas generator and an airbag. The gas generator is riveted and bolted to a metal bracket. The airbag is protected by a plastic sleeve with crack initiators that is fitted to the metal bracket. The airbag has a volume of 70 litres.

The airbag is connected between pin 10 and 11 on the control module.

A special contact roller transmits test and detonation power to the airbag.

Airbag gas generators

The gas generator consists of an aluminium casing divided into a central chamber and two annular chambers. The centre 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 on combustion develops a gas, which reaches a filter in the outer annular chamber through passageways. The filter cleans the gases from particles before it passes out to the airbag.
