Airbag Modules

Airbag modules

General




Each airbag module consists of an inflatable bag and a gas generator. These are mounted as one unit in the center of the steering wheel and in the dashboard.

Warning! Airbag modules must never be disassembled, repaired or transferred to another vehicle.

If the car is to be scrapped or the airbag replaced, see Handling non-deployed airbag modules/pyrotechnic seat-belt tensioners Handling Non-Deployed Airbag Modules/Pyrotechnic Seat-Belt Tensioners.

Note! Volvo recommends that airbag modules be replaced every 10 years to maintain reliability.

Steering wheel module




The steering wheel module consists of an electrical igniter (A) mounted in gas generator (B) which opens into to the folded airbag. When the igniter receives an electrical signal from the sensor module, the gas generator produces a harmless gas which rapidly inflates the airbag.

Passenger module




The passenger module is constructed in the same way as the steering wheel module, with the distinction that the gas generator is adapted to the greater volume of the airbag.

Warning! Never put a child seat on the front passenger seat if the car is equipped with an SRS (Airbag) on the passenger side.

SRS Decals - Warning and Information Decals Inside the Car (On the Side of the Dashboard on the Passengers Side):

Disconnecting the passenger airbag module
The passenger airbag module SRS ignition cable can be disconnected in accordance with the car owner's wishes in markets where this does not conflict with statutory requirements. This makes it possible to place a rear facing child seat on the front passenger seat.

Airbag




The airbag is folded on top of the gas generator in the airbag modules. When inflated, the volume of the airbag is approx. 150 liters (40 US gallons) on the passenger side and approx. 60 liters (16 US gallons) on the driver's side.
The airbag is made of heavy duty polyamide fabric with venting holes. The gas escapes through the venting holes so that the airbag collapses at the right speed to arrest the forward movement of the driver and passenger.

Gas generator
There is a gas generator in every airbag module. The gas generator is a sealed unit made of aluminum or steel. This contains a propellant that forms a harmless gas. As was mentioned earlier the airbag inflates very rapidly.
