Airbag device for front passenger seat

摘要

An airbag for an airbag device for a front passenger seat is housed in a housing in the shape of a folded-up body in front of a front passenger seat. The airbag includes a main bag section that includes at the rear plane as deployed a front-collision arresting plane for catching a passenger as moves forward and an auxiliary bag section that protrudes rearward out of the front-collision arresting plane. The lateral of the auxiliary bag section facing towards the front-collision arresting plane serves as an oblique-collision arresting plane for catching the passenger as moves diagonally forward, The folded-up body of the airbag includes a means for temporarily jointing the auxiliary bag section in a folded up configuration to the main bag section and preventing the auxiliary bag section from protruding out of the front-collision arresting plane in an initial stage of airbag deployment.
