Air bag module with vent

An apparatus helps protect an occupant of a vehicle. The apparatus includes an inflatable vehicle occupant protection device that is inflatable to help protect the vehicle occupant. A vent opening directs flow of inflation fluid away from the protection device. A vent member is movable between an open condition enabling flow of inflation fluid away from the protection device through the vent opening and a closed condition at least partially blocking flow of inflation fluid away from the protection device through the vent opening. A panel receives and transfers the force of inflation directed into the protection device to the vent member to urge the vent member toward the closed condition.
