Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
121 words
In a motor vehicle passenger side restraint module of the type including a housing mounted behind the instrument panel of the vehicle having edges defining an open mouth closely adjacent said panel, an airbag stowed within said housing, means for inflating said airbag upon the occurrence of a collision of preselected magnitude, and a door in said instrument panel covering the open mouth of said housing and displaceable by the inflation of said airbag, the improvement comprising: a relatively thin sheet mounted between said door and said housing defining a plurality of elongated corrugations spanning the open mouth of said housing and crushable against the edges of said housing to absorb energy and protect an occupant upon impact with said door.
Claim 2
Dependent Claim
