id081000100700
• The curtain air bag modules are equipped along the roof edge between the A and C pillars.
• Consists of an inflator, bag cover, and air bag.
• When the curtain air bag operates (deploys), the A-pillar trim and headliner is spread apart by gas generated from the inflator, inflating the air bag.

• The inflator operates (deploys) in the following order:

  1. When an operation (deployment) signal is received from the SAS control module, the igniter 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.
