ABSTRACT:
An air bag module includes an inflator and an air bag for inflation. The air bag includes retainer bars for attachment of the air bag to the housing. The module further includes an axially elongated, open-ended, generally cylindrical extruded housing having a circular-shaped cross section defined by a single cylindrical wall having an internal wall surface and an external wall surface. The housing includes integrally extruded air bag channels directly disposed on the external wall surface. The integrally extruded air bag channels axially receive the retainer bars of the air bag therein for attachment of the air bag to the housing such that the cylindrical wall and the air bag channels form a generally cylindrical-shaped housing which is lightweight and compact. Preferably, the module includes exactly two integrally formed channels directly disposed on the housing and a cover having axially extending enlarged portions thereon. The enlarged portions are preferably hollow and sized and shaped for receiving the retainer bars and enlarged portions therein. Thus, exactly two channels on the housing advantageously mount both the air bag and the cover to the housing.
