Purpose
• When the vehicle receives an impact from a lateral collision, the side air bag module operates (deploys) the air bag to mediate the impact to the chest, abdomen, and the waist part of the driver and front passenger.
Function
• When the vehicle receives an impact from a lateral collision, the side air bag module operates (deploys) the air bag based on the operation signal sent from the SAS control module.

Operation
• The side air bag module operates (deploys) the air bag by activating the internal inflator.
• The inflator operates (deploys) in the following order:
-
1. When an operation (deployment) signal is received from the SAS control module, the initiator ignites.2. The ignition of the initiator causes the combustion of gas-generating agent A which generates gas (1).3. The generated burnt gas causes the combustion of gas-generating agent B which generates gas (2).4. The generated burnt gas breaks through the seal tape (3), and is injected into the air bag (4) through the diffuser.
