Abstract

The reaction canister of a passenger-side motor vehicle airbag module is extruded with a groove in at least one side wall forming a thinned section running the length of the canister. This creates a weakened and bendable region which allows the side wall to buckle under an impact through the instrument panel of the vehicle. This buckling absorbs impact energy, avoiding or reducing injury to the occupant.
