ABSTRACT:
The present invention provides a new and useful housing structure for an inflator, particularly an inflator for a vehicle air bag system. The inflator housing has a wall with gas dispensing nozzles extending through it. The wall is (i) relatively thick in certain areas (e.g., the nozzle area), to provide adequate resistance to gas pressures and thrust forces applied to the housing during operation of the inflator, and (ii) relatively thin in certain other areas, to reduce the weight of the inflator. The housing is preferably constructed of a lightweight material (e.g., aluminum). The housing configuration of the present invention helps further reduce the weight of the inflator, while not unduly reducing the strength of the inflator to withstand the gas pressures and thrust forces applied to the housing during operation of the inflator.
