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 ignition of the inflation agent causes the combustion of an agent which releases nitrogen gas.
3. The nitrogen gas is cooled at the filter, and the filtrate is injected into the air bag.
