ABSTRACT:
An inflator (10) is provided for supplying gas to a vehicle airbag from the combustion of pyrotechnic materials. The inflator (10) has a two-piece inflator body (12) held together by crimping the body components, rather than welding. An igniter assembly (18) is positioned in a bore (22) in an upper piece (14) of the inflator body and is held in place with a press-fit interface and an adhesive seal. The upper piece (14) of the inflator body is rounded, increasing its strength, and fits partially into the lower piece (16). A booster tube is unnecessary, making the inflator lighter in weight and increasing available volume for propellant.
