SIDE AIR BAG MODULE CONSTRUCTION/OPERATION
CHU081000147S02
Construction
• Side air bag modules are installed on the outboard sides of the front seat backs.
• The side air bag module is composed of an inflator, module cover and air bag.
• When an air bag deploys, the side air bag module cover is spread apart by the generation of argon gas from
the inflator, inflating the air bag.
Operation
Air bag module deployment operation
• Refer to the SAS CONTROL MODULE DESCRIPTION, Air Bag Module and Pre-tensioner Seat Belt
Deployment Operation. (See 08–10–4 SAS CONTROL MODULE CONSTRUCTION/OPERATION.)
Inflator operation
1. The igniter built into the inflator begins to build up heat when the operation (deployment) signal is sent from the
SAS control module. The inflation agent is ignited by the build up of heat in the igniter.
2. The argon gas expands due to the heat of the ignited inflation agent.
3. The expanding argon gas breaks the discharge barrier, is cooled and filtered by the filter, and then injected into
the air bag.
