13. A vehicle occupant protection apparatus comprising:
-
an inflatable occupant protection device;
a support member having a vent opening through which inflation fluid may flow;
a bag retainer securing the inflatable occupant protection device relative to the support member;
a vent member that is movable relative to the support member for controlling a flow of inflation fluid through the vent opening;
a tether extending between the inflatable occupant protection device and the vent member, the tether being responsive to inflation of the inflatable occupant protection device beyond a predetermined distance for moving the vent member;
a tether guide member for guiding the tether between the inflatable vehicle occupant protection device and the vent member, the tether guide member being located on the bag retainer; and
a locking member for acting on the tether to block movement of the vent member that would otherwise increase the flow of inflation fluid through the vent opening after the inflatable occupant protection device has inflated beyond the predetermined distance. - View Dependent Claims (14, 15, 16, 17, 18, 19)
