ABSTRACT:
A vehicle occupant protection apparatus (10c) has an inflatable occupant protection device (12c) and a support member (20c) having a vent opening (44c). A vent member (46c) is associated with the vent opening (44c). A tether (50c) extends between the protection device (12c) and the vent member (46c). The vent member (46c) is initially in a first condition closing the vent opening (44c). The vent member (46c) is moved to a second condition spaced apart from the vent opening (44c) and enabling fluid flow through the vent opening (44c) upon initial inflation of the protection device (12c). The vent member (46c) is moved from the second condition back toward the first condition by tension in the tether (50c) that results from inflation of the protection device (12c) away from the support member (20c) by more than a predetermined distance.
