CURTAIN AIR BAG MODULE CONSTRUCTION/OPERATION
id081000100700
Construction
•
The curtain air bag modules are equipped along the roof edge between the A and D pillars.
•
The curtain air bag module is composed of the inflator and air bag.
•
When the curtain air bag operates (deploys), the A-pillar trim and headliner are spread apart by gas generated
from the inflator, inflating the air bag and maintaining the gas reserve for
approx. 6 s .
•
A stored-type inflator has been adopted instead of using an ignition agent in the inflator.
Operation
Inflator operation
1. When an operation (deployment) signal is received from the SAS control module, the igniter ignites.
2. The ignition causes the discharge area of the wall to open and compressed gas is released.
3. The compressed gas passes through the filter and the filtrate is injected into the air bag.
