Abstract
The reaction canister of an airbag module assembly is extruded to include a semicircular floor, first and second sidewalls, and first and second end plates closing the ends of the canister, with the floor extending uniformly between the sidewalls, and a bottom edge of each sidewall defining a channel along its length. A cylindrical inflator chamber is suspended beneath the floor of the canister by opposed parallel wings which are integral with the inflator chamber and are insertable into and slide in the channels to a position wherein the walls of the channel are staked to the wings. A plenum chamber is formed between the curved wall of the inflator chamber and the floor of the reaction canister. The plenum chamber separates gas exit vent holes of the inflator chamber from gas inlet passages or vent holes in the canister floor. The plenum chamber is closed by the canister end plates which seal the plenum chamber by engaging the adjacent ends of the wings of the inflator chamber and the adjacent ends of the canister floor and of the channels. The module assembly requires only eight fasteners, that is, four on each end of the canister.
