ABSTRACT:
An inflator for a protective air bag is arranged for initiation by an ignition squib assembly that is adapted to be incorporated in the inflator housing structure after assembly thereof with the inflator pyrotechnics contained therein. The ignition squib assembly includes a sleeve having a circular crimp on a first end region thereof with a collar on the sleeve in tight embracing relation with that region. Igniting materials including an electrical squib and ferrite beads are potted in the sleeve. The sleeve and attached collar are pressed in a hole in the wall of the housing structure defining the inflator ignition chamber with a second end region of the sleeve extending into the ignition chamber and an inner end of the collar abutting an O-ring in the hole to provide a seal. A lip on the hole is rolled over the collar to prevent the ignition squib assembly from being pulled out of the hole.
