Abstract

An air bag module (50) comprising an inflator (40) for generating inflation gas; an air bag (12) disposed about the inflator to receive the inflation gas exiting the inflator; a structure (52) for supporting at least the inflator. The inflator comprises: a pressure vessel (42) and a plurality of exit ports (16). The exit ports are arranged to render the inflator in a thrust neutral condition when the inflator is not attached to the structure. A plug (60) or plugs is provided for closing a designated set of exit ports to render the inflator in a non-thrust neutral condition when supported by the structure. Each plug is received in each of the designated exit ports and is preferably received though a portion of the structure such that if the inflator is removed from the structure each plug must also be removed, thereby opening all of previously closed exit ports and rendering the inflator in its thrust neutral condition once again.
