US Patent 8925962 Vehicle airbag structure

A vehicle airbag structure deploying an airbag at a predetermined designed position in an initial stage of deployment, while suppressing a swinging motion, to allow the airbag to continuously deploy and inflate toward a vehicle seat and reliably receive an occupant at an appropriate position. The vehicle airbag structure includes: an intermediate panel provided between a front panel and a rear panel; a joining the rear panel and the front panel to form an airbag; an intermediate panel forming a gas duct to guide inflator gas; and a gas circulation hole formed by a portion of the intermediate panel facing in a circumferential direction to generate, inside the airbag, a gas flow in the circumferential direction.
