Abstract
Abstract An inflatable restraint cushion for restraining a vehicle occupant is used in a vehicle having a vehicle side structure including a door having a beltline portion defining a lower boundary of a side window opening. The cushion includes an inboard contact face for inflation adjacent the vehicle occupant and an opposite outboard contact face for inflation adjacent the vehicle door. The outboard contact face includes a generally horizontally extending beltline notch portion shaped for matably aligning with and engaging the beltline portion of the door when the cushion is inflated. Upon engagement of the cushion by the occupant, the beltline notch portion of the cushion reacts against and is laterally and vertically supported by the beltline portion of the door to provide lateral stability to the cushion.
