Patent ID: 7398992

Claim:
An air bag, comprising: a. a first panel portion; b. a second panel portion, wherein when mounted in a vehicle and inflated therein, said first panel portion defines a vehicle forward boundary of the air bag, said second panel portion defines a vehicle rearward boundary of the air bag, and said first and second panel portions are part of an exterior boundary of said air bag; c. a first opening, operatively associated with said first panel portion, wherein said first opening is adapted to receive inflation gas from a gas generator; d. an inner panel operatively coupled and adjacent to said first panel portion, wherein said inner panel is located within said exterior boundary of said air bag, wherein two opposing sides of the inner panel are attached to the first panel portion to form a duct with a volume located between the two attached sides and defined by the inner panel and first panel portion, a portion of said inner panel proximate to a first end thereof substantially surrounds said first opening at a first end of said duct so as to provide for receiving a substantial majority of inflation gas from said gas generator, said inner panel extends from said first end thereof to a second end thereof along a portion of said first panel portion towards a distal portion of the airbag and spaced from said second panel portion during inflation, wherein said distal end of said airbag is distal relative to said first opening, and said second end of said inner panel defines a second end of said duct, and said duct provides for discharging said inflation gas into a first volume portion of the air bag bounded by said first panel portion, wherein said first volume portion is substantially greater than a volume of said duct.
