Driver's side air bag module

DRIVER'S SIDE AIR BAG MODULE

The bag is made out of silicon-coated nylon. Inner volume is 40 litres when the bag is fully inflated. The bag is folded into a plastic case in the steering wheel hub.

The case is fitted with a cover with pre-established break lines in the middle. This allows the central part to break out so that the bag can emerge.

Because the cover is plastic, it must under no circumstances be cleaned with acids, abrasives or substances that could damage the surface and affect operation in any way.
The gas generator is pyrotechnic and looks like a ring-shaped aluminium solid.

The generator consists of the following parts:

• aluminium container in two halves. The half turned toward the car interior is perforated to allow gas to emerge. The entire system is sealed.
• the sodium azide is contained in a ring-shaped solid and produces a considerable quantity of gas when heated. The detonator triggers the chemical reaction to inflate the bag.
