Patent ID: 8393636

Claim:
An airbag device for a vehicle comprising: at least one airbag housing interface chamber that attaches to an airbag housing; at least one airbag cushion chamber downstream of the at least one housing interface chamber; at least one elbow that fluidly connects the at least one housing interface chamber with the at least one airbag cushion chamber and is configured so that the at least one elbow controllably regulates gas flow into the at least one airbag cushion chamber via at least one opening that permits back and forth gas flow between the elbow and the at least one airbag cushion chamber; the at least one elbow having an internal configuration, which controls directional deployment of the at least one airbag cushion chamber so that upon deployment a downstream end of the at least one airbag cushion chamber exits an airbag housing outwardly in a first direction and then in at least one second direction, so that the direction of deployment of the cushion chamber changes between the first direction and the second direction to thereby wraps at least partially around a component of the vehicle and at least temporarily interposes the cushion chamber between an occupant and the component; and wherein the elbow has an inner facing panel with a length A, and an outer facing panel with a length C that is longer than at least about 1.5 times the length A, the inner facing panel being tethered to the outer facing panel by a first tether located proximate to the interface chamber, the first tether having a tether length B and a second tether, having a tether length D that is longer than the length B.
