Abstract:
An apparatus (10) for helping to protect an occupant (20) of a vehicle (12) comprises an inflatable vehicle occupant protection device (14) inflatable between a vehicle surface (36) and the vehicle occupant. A vent (160) releases inflation fluid from the protection device (14). The vent (160) includes a vent opening with a flow area that can be adjusted to throttle inflation fluid flow through the vent. A tether (150) has a first connection with the vent (160) and a second connection with the protection device (14). Tension on the tether (150) throttles the vent (160). The second connection of the tether is positioned on the protection device (14) such that deployment of the protection device throttles the vent (160) toward an actuated condition, and occupant (20) penetration into the protection device throttles the vent toward a non-actuated condition.
