Schematic procedure
The figures are illustrations of the principle and are not vehicle-specific

1. Depending upon the severity of the impact the restraint systems control unit (N2/7) sends an electrical ignition pulse to the gas generator's driver airbag ignition squib 1 (R12/13) and driver airbag ignition squib 2 (R12/14). The type of crash involved determines whether the detonators are ignited simultaneously or in stages.
2. The ignition squibs then ignite the solid fuel in the inflator. When the solid fuel burns it generates a gas that flows "explosively" under high pressure through a filter and into the interior of the airbag folded compactly on top of the inflator.







3. The bag folded on top of the gas generator then inflates, forcing open the steering wheel hub cover along a predetermined fracture point.
4. As more gas enters the bag, it pushes through the opening and fills to maximum volume.







5. The airbag reaches its full volume within approximately 45 msec.
6. It begins to deflate immediately after attaining maximum volume. The gas escapes from the airbag through a filter and the airbag collapses.

Disposal
After a triggering stage has been activated, the unit must be disposed of accordingly. In Germany disposal is possible through the Mercedes-Benz Recycling System "MeRSy". The corresponding legal requirements should be observed in all other countries.
