Passenger airbag gas generator

The gas generator consists of an aluminum casing divided into an inner chamber, a center chamber and two annular chambers.

In the inner chamber is an electric detonator and an explosive charge which is connected to the center chamber.

The center chamber contains a fuel in tablet form which releases a gas when it is burned. The center chamber is connected to both the outer chambers via passages equipped with filters. The filter separates particles from the gas.

In the outer chamber, the gas passes through a further filter before it reaches the air bag.
