Abstract: An apparatus for controlling flow of inflation fluid through a vent opening (50) in an air bag module (10) includes a vent member (14) movable to control flow of the inflation fluid through the vent opening. The vent member (14) includes a vent member opening (84) extending through the vent member. A tether (12) for controlling movement of the vent member (14) includes a first portion (90) and second portion (92). The second portion (92) is folded to form multiple layers (112, 114). The tether (12) is positioned relative to the vent member (14) so that the multiple layers (112, 114) of the second portion (92) engage a first side (62) of the vent member. The first portion (90) of the tether (12) extends through the vent member opening (50) and away from an opposite second side (60) of the vent member (14). The engagement of the second portion (92) with the vent member (14) causes the vent member (14) to move in response to movement of the tether (12).

Abstract: A vehicle occupant protection apparatus (800) includes an inflatable occupant protection device (802) and a vent opening (876) through which inflation fluid may flow. The vehicle occupant protection apparatus (800) also includes a retainer (910) to which the protection device (802) is secured. A vent member (890) is movable relative to the vent opening (876) for controlling a flow of inflation fluid through the vent opening (876). A tether (990) is movable in response to inflation of the protection device (802) beyond a predetermined distance for moving the vent member (824). A tether guide member (940) is located on the retainer (910) for guiding the tether (990).
