Abstract
A housing for an air bag inflator includes a tubular wall and gas dispensing nozzles extending through at least a portion of the wall. The tubular wall defines an inflator cavity for receiving a source of gas. The inflator housing includes a tongue formed in one piece with one end of the housing and projecting outwardly from the housing. The tongue includes a planar surface adapted to be coupled to a planar wall of a reaction device. The inflator housing further includes a sleeve attached to the tubular wall axially spaced from the tongue. The sleeve includes diametrically opposed flanges extending outward from the sleeve. Each of the flanges include a planar surface adapted to be coupled adjacent the planar wall of the reaction device. The tongue includes an alignment device which provides for properly aligning the inflator with the reaction device. According to another aspect of the invention, the inflator housing structure includes a pair of sleeves attached to axially spaced portions of the housing. A surface of at least one of the flanges includes an alignment device for providing proper alignment of the inflator with the air bag module.
