Location

The front passenger airbag unit with the integrated front passenger airbag squib is located in the instrument panel above the glove box.

Task

The front passenger airbag unit protects the front passenger or the front passengers, on vehicles with code (S23) Two-seater front passenger seat from injury in the event of a head-on collision. The front passenger is caught and slowed by the airbag of the front passenger airbag unit, which fills up the space between the instrument panel and the front passenger 's body.

Function

Depending on the severity of the accident, an electric ignition pulse is output to the front passenger airbag squib via the control unit that is installed depending on the variant. The front passenger airbag squib ignites the solid fuel in the gas generator. When the solid fuel is burning off, a bursting disk is opened, which then releases the compressed gas from the pressure reservoir. The airbag which is folded on top of the gas generator then inflates and, under the pressure of the gas flowing in, forces open the front passenger airbag unit in the instrument panel at a predetermined fracture point. As more gas enters the bag, it pushes through the predetermined fracture point and fills to maximum volume. This is followed by depressurization in the airbag. The gas escapes from the airbag through the airbag fabric and the airbag collapses.

A distinction between the equipment variants has to be made as follows:
- Lowline airbag control unit (N2/14), except code (SH6) Thorax bag for driver (in seat backrest), except code (SH7) Thorax bag for driver and front passenger (in seat backrest) and except code (SH9) Window bag for driver and front passenger
- Highline airbag control unit, with code (SH6) Thorax bag driver (in seat backrest), with code (SH7) Thorax bag for driver and front passenger (in seat backrest) or with (SH9) Window bag for driver and front passenger
In order to prevent inadvertent triggering, the front passenger airbag squib is equipped with a short circuit bridge, which automatically short circuits the connection if the coupling is disconnected.

Disposal

The front passenger airbag unit must be disposed of appropriately after the ignition stage has been triggered. In Germany disposal is possible through the Mercedes-Benz Recycling System "MeRSy". In all other countries, please observe applicable regulations.
