SIDE AIR BAG MODULE CONSTRUCTION/OPERATION

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 and air bag.
• When the air bag operates (deploys), the seat back trim is spread apart by argon gas generated from the
inflator, inflating the air bag.
• The inflator operates in the following order:
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 inflammation agent is ignited by the build up of heat in the igniter.
2. The argon gas expands due to the heat of the ignited inflammation agent.
3. The expanding argon gas breaks the discharge barrier, is cooled and filtered by the filter, and then injected
into the air bag.
