Inflator Operation

1.  When an operation (deployment) signal is received from the SAS control module, the igniter built into the inflator generates heat and ignites the ignition agent.

2.  The ignition of the ignition agent causes the combustion of a gas generating agent which forms nitrogen gas.

3.  The nitrogen gas is cooled at the filter and the filtrate is injected into the air bag.
