Airbags woven protective shieldsThe purpose of airbags is to slow an occupant's motion as evenly as possible in a fraction of a second in a crash. Airbags are supplemental restraints and work best in combination with seatbelts.The airbag consists of a folded textile cushion designed to inflate quickly inside the vehicle immediately after a collision. Most airbags are inflated pyrotechnically and can only be deployed once. There are four main parts in an airbag module (from right to left): An inflator that produces sufficient gas to inflate the folded bag.A textile cushion made of thin, woven nylon or polyester fabric. A housing for storing the folded bag and the inflator. The housing can be made of steel, plastic or even textile.A cover that opens as the cushion inflates.
