Purpose
When a curtain air bag module receives an impact from a lateral collision, the operation (deployment) of the air bag mediates the impact to the head of the driver and front passenger.
Function
When a curtain air bag module receives an impact from a lateral collision, the air bag is operated (deployed) by the operation signal sent from the SAS control module.
Construction
The curtain air bag module is installed along the roof edge between the A and C pillars.
The curtain air bag module consists of the inflator and air bag.
A stored-type curtain air bag has been adopted which does not use an ignition agent for the inflator.
Operation
The curtain 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 igniter built into the inflator generates heat and ignites the ignition agent.
2. The combustion of the ignition agent causes the ignition of a gas agent. The section of the wall from which the air bag deploys is broken by this impact wave.
3. The gas generated by the sealed argon gas and gas-generating agent is cooled at the filter and the filtrate is injected into the air bag.
4. When a curtain air bag operates (deploys), the A-pillar trim and headliner are spread apart by the compressed gas generated from the inflator, inflating the air bag.
