Patent ID: 7770922

Claim:
An airbag assembly, comprising: an airbag assembly housing having first housing aperture and a second housing aperture; an inflatable airbag cushion disposed inside the airbag assembly housing; wherein the inflatable airbag cushion comprises a cushion membrane having a first vent aperture and a second vent aperture, wherein the first vent aperture and the second vent aperture are located opposite each other in opposing sides of the airbag cushion, and wherein the inflatable airbag cushion further comprises two tabs that are each respectively coupled near a perimeter of each vent aperture, each tab protruding through the housing aperture adjacent to the respective vent aperture, and each tab is coupled to a side wall of the housing, wherein the first vent aperture is initially aligned with the first housing aperture and the second vent aperture is initially aligned with the second housing aperture such that during inflatable airbag cushion deployment with obstruction, the first vent aperture remains at least partially aligned with the first housing aperture and the second vent aperture remains at least partially aligned with the second housing aperture, thereby allowing inflation gas to exit the airbag cushion via vent and apertures, and wherein during inflatable airbag cushion deployment without obstruction, the vent apertures move as the inflatable airbag cushion expands such that the vent apertures become misaligned with respect to the housing apertures, whereby inflation gas directed toward the housing apertures is blocked from exiting through the housing apertures by the cushion membrane and the inflatable airbag cushion fully expands.
