Passenger protection

Front passenger airbag N131 and N132
Like the driver airbag, the passenger airbag also
comes with a two-stage gas generator. In contrast to
the driver's airbag, the gas generator in the front
passenger airbag operates according to the hybrid
gas technique. The gas generator comprises two
pyrotechnical propelling charges and a compressed
gas bottle. The airbag control unit ignites the first
propelling charge. The pressure which is produced
accelerates a piston, which opens the gas cylinder.
The escaping gas inflates and fills the airbag. The
ignition of the second propelling charge supplies
the airbag with an additional volume of gas.
