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 (110) has at least one opening (114) for releasing inflation fluid from the protection device (14). The vent (110) has an actuated condition and a non-actuated condition. A guide tether (113) is connected to the vent door (120). A vent tether (112) is connected to the protection device (14) and includes a guide (123) connected to the guide tether (113) such that the guide (123) and guide tether (113) are slidable relative to one another. Tension on the vent tether (112) applies tension to the guide tether (113) for actuating the vent (110). The vent (110) is configured to be initially in the non-actuated condition upon initial deployment of the protection device (14), with further deployment of the protection device (14) to a predetermined degree causing the vent tether (112) to act on the guide tether (113) to place the vent (110) in the actuated condition.
