More Information
Summary:dA vehicle occupant protection apparatus includes an inflatable occupant protection device and a support member. A vent opening extends through the support member. A vent member is associated with the vent opening. The vent member initially closes the vent opening. Inflation fluid moves the vent member relative to the support member for enabling a flow of inflation fluid through the vent opening. A tether extends between the inflatable occupant protection device and the vent member. The tether is responsive to inflation of the inflatable occupant protection device away from the support member by more than a predetermined distance for moving the vent member relative to the support member for reducing the flow of inflation fluid through the vent opening.
