Inflator Operation
Inflator No.1
1. When the driver-side air bag module receives an operation (deployment) signal from the SAS control module,
the igniter built into inflator No.1 builds up heat and ignites the inflammation agent.
2. The ignition of the inflammation agent causes the combustion of a gas-generating agent which releases
nitrogen gas.
3. The nitrogen gas is cooled at the filter and the filtrate is injected into the air bag.
Inflator No.2
1. When the driver-side air bag module receives an operation (deployment) signal from the SAS control module,
the igniter built into inflator No.2 builds up heat and ignites the inflammation agent.
2. The ignition of the inflammation agent causes the combustion of a gas-generating agent which releases
nitrogen gas.
3. The nitrogen gas is cooled at the filter and the filtrate is injected into the air bag.
