Air bag module having a closure device for closing vents in response to full extension of the air bag
First Claim
1. A vehicle occupant protection apparatus comprising:
- a housing including a flow opening through which fluid may flow;
an inflatable occupant protection device being inflatable from a stored condition to an inflated condition, structure of the inflatable occupant protection device defining an inflatable volume of the inflatable occupant protection device; and
a closure device being movable relative to the housing from a first position to a second position for restricting fluid flow through the flow opening, the structure of the inflatable occupant protection device being attached to the closure device, a force results from the structure of the inflatable occupant protection device reaching a full extension during inflation from the stored condition to the inflated condition, the force acting through the structure of the inflatable occupant protection device that is attached to the closure device and moving the closure device from the first position to the second position.

Abstract
A vehicle occupant protection apparatus (10) includes a housing (30). The housing (30) includes a flow opening (70, 98) through which fluid may flow. The vehicle occupant protection apparatus also includes an inflatable occupant protection device (14) that is inflatable from a stored condition to an inflated condition. Structure (18, 20) of the inflatable occupant protection device (14) defines an inflatable volume of the inflatable occupant protection device (14). A closure device (120) is movable relative to the housing (30) from a first position to a second position for restricting fluid flow through the flow opening (70, 98). The structure (18, 20) of the inflatable occupant protection device (14) is attached to the closure device (120). A force resulting from the inflatable occupant protection device (14) reaching full extension moves the closure device (120) from the first position to the second position.
