Abstract
Abstract A vehicle occupant restraint system comprises an inflatable air bag (12), an air bag canister (24) having walls defining an interior chamber (25) in which the air bag is stored, and a source of inflation fluid (20) for inflating the air bag. The source of inflation fluid includes (i) an inflator body (21) having opposite ends and (ii) a nozzle opening (23) disposed at one end of the inflator body. A deflector panel (50) is attached to the air bag. The deflector panel defines an opening (45) through which inflation fluid flows to inflate the air bag. The deflector panel has surfaces (71, 72) that deflect inflation fluid flow from the nozzle opening (23) and through the opening (45).

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
101 words
A vehicle occupant restraint system comprising: an inflatable air bag; a source of inflation fluid for inflating said air bag, said source of inflation fluid including (i) an inflator body having opposite ends and (ii) a nozzle opening disposed at one end of said inflator body; deflector panel means attached to said air bag for (i) defining an opening through which inflation fluid flows into said air bag to inflate said air bag and (ii) deflecting a portion of the inflation fluid flow from said nozzle opening disposed at said one end of said inflator body to flow through said opening.
Claim 2
Dependent Claim
31 words
A vehicle occupant restraint system according to claim 1 wherein said source of inflation fluid comprises an augment inflator having nozzle openings only at said one end of said inflator body.
Claim 3
Dependent Claim
29 words
A vehicle occupant restraint system according to claim 1 wherein said deflector panel means comprises at least one fabric panel which is folded to form said deflector panel means.
Claim 4
Dependent Claim
52 words
A vehicle occupant restraint system according to claim 3 wherein at least one major side surface of said panel is coated with silicon, said silicon coated major side surface of said layer of fabric facing toward said source of inflation fluid to deflect inflation fluid flow from said source of inflation fluid.
Claim 5
Dependent Claim
19 words
A vehicle occupant restraint system according to claim 3 wherein said panel is made of 420 denier nylon 6/6.
Claim 6
Dependent Claim
