Abstract

An inflator assembly for an airbag safety system that comprises a container having a chamber configured to hold pressurized gases, an igniting assembly for producing exit gases and a diffusing assembly to vent the exit gases. The container is provided with an end closure that is composed of a material having a substantial silicon content. The diffusing assembly includes a diffuser cap and a burst disk. The diffuser cap has a number of apertures formed therein that allow the exit gases to be released when the burst disk ruptures. The igniting assembly is configured such that it may be coupled to the end closure and capable of withstanding a heat treatment process that bonds the igniting assembly, end closure and container together to form a one-piece structure.
