Abstract

An airbag cushion is disclosed for use in automotive protective systems. The airbag cushion includes a tube that may be restricted to prevent gas venting. A cord is coupled to the tube and to a surface of the cushion. Upon airbag deployment, the cord extends until taut or extends until the cushion encounters an obstruction. If pulled taut, the cord tightens the tube and restricts gas venting. If the cushion encounters an obstruction, the cord remains lax and the tube is able to vent gas.
