Abstract
A deep drawn reaction canister encloses a hybrid inflator. In order to evenly inflate an airbag, a diffuser sheet is positioned over the inflator to distribute the gases which exit one end of the inflator. The diffuser sheet serves a second function of securing the inflator in the canister. It does so by means of screws which extend through the canister and into threaded engagement with the diffuser sheet, placing it in tension when the screws are tightened.
