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 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.
