Abstract
Abstract A passenger side airbag module includes a reaction canister whose sidewalls define a pair of channels on opposite sides of its open mouth. An unperforated cushion cover carries a pair of splines which are engaged by the channels. One spline/channel combination locks the cover securely to the canister. The other spline/channel combination forms a snap-fit engagement which disengages under the force of the expanding airbag.
