CURTAIN AIR BAG MODULE

The curtain air bag module consists of an air bag, an inflator, and the fixing gear relating to those parts, and is installed in the roof side sections (from the driver's and the passenger's front pillars to the rear pillars).
The air bag is made from nylon with the inside coated with silicon, and housed in the roof side sections, folded up compactly.
The inflator is of a hybrid type filled with high-pressure gas (major component: argon). When current passes through the squib to ignite the igniter powder, the burst disk bursts, letting the gas spur out of the nozzle.
