Abstract
An inflator (10) for use in an inflatable vehicle occupant protection system. In one aspect, the inflator (10) includes a longitudinal enclosure (22) having a substantially uniform cross-sectional area along at least a portion of the enclosure, and a gas generant composition (24) positioned along the portion of the enclosure (22). The gas generant composition (24) is distributed substantially uniformly along the portion of the enclosure (22). A plurality of gas exit apertures (40) is formed along the portion of the enclosure (22) to enable fluid communication between the enclosure (22) and an exterior of the enclosure. The apertures (40) are spaced apart a distance proportional to a desired rate of propagation of a combustion reaction of gas generant positioned between the apertures (40). In another aspect of the invention, the total number of apertures (40) along the enclosure (22) is inversely proportional to a desired rate of propagation of a combustion reaction of gas generant positioned between the apertures (40). An airbag system (100) incorporating the inflator (10) and methods of attaching the airbag system to a vehicle are also disclosed.
