Air bag valve assembly
First Claim
1. An air bag valve assembly for installation in an opening in a fabric wall of an air bag, comprising:
- first and second panels of flexible sheet material overlying one another and being permeable to pass gas therethrough and having edge portions joined together to form a housing envelope;
a valve flap panel of flexible sheet material interposed between the first and second panels so that the valve flap panel is supported for movement across the first and second panels;
and a tether having a first end operably associated with the valve flap panel and a second end operable to actuate the tether and move the valve flap across the gas permeable first and second panels.

Abstract
An air bag valve assembly for installation in an opening in the fabric wall of an air bag includes first and second housing panels of flexible sheet material which overlie one another and are permeable to pass gas therethrough. The edge portions of the housing panels are stitched together to form a housing envelope in which a valve flap panel of flexible sheet material is supported. A tether is attached to the valve flap panel to move the valve flap panel across the gas permeable first and second panels when the tether is actuated. The valve assembly may be normally closed by using a gas impermeable material for the valve flap panel. Alternatively, the valve assembly may be normally open and then the actuation of the tether pulls a gas impermeable valve flap across the gas permeable first and second panels to block the flow of gas. The housing panels may be of a gas impermeable fabric having holes cut therein, or the panels may be an open weave mesh construction to pass gas therethrough.
