PROBLEM TO BE SOLVED: To control internal pressure of an airbag during oblique restriction to higher internal pressure than that of the airbag during head-on collision restriction.SOLUTION: In a front passenger seat airbag device 20, an airbag 24 includes: a body bag section 26 inflated and deployed in front of a front passenger P; and a center bag section 28 inflated and deployed on a driver seat side with respect to the body bag section 26. A slit 24A2 is formed to open on a vehicle rear side between the center bag section 28 and the body bag section 26 during inflation and deployment, and the center bag section projects to a vehicle rear side of the body bag section 26. A second vent hole 28H (vent hole) is formed in a side section 28C on the driver seat side of the center bag section 28. A vent hole variable mechanism 33 connects the side section 28C on the driver side of the center bag section 28 to a side section 28A on the front passenger seat side of the center bag section 28 and is configured to squeeze more gas exhaust amount from the second vent hole 28H during oblique restriction than that during head-on collision restriction.SELECTED DRAWING: Figure 1

    【課題】オブリーク拘束時のエアバッグの内圧を、正突拘束時のエアバッグの内圧よりも高い内圧に制御する。【解決手段】助手席エアバッグ装置20では、エアバッグ24が、助手席乗員Pの前方で膨張展開される本体バッグ部26と、本体バッグ部26に対する運転席側で膨張展開されるセンタバッグ部28と、を含んで構成されている。センタバッグ部28は、膨張展開時に、本体バッグ部26との間に車両後方側に開口するスリット24A2が形成されると共に本体バッグ部26よりも車両後方へ突出する。センタバッグ部28の運転席側の側部28Cには、第二ベントホール28H(ベントホール)が形成されている。ベントホール可変機構33は、センタバッグ部28の運転手側の側部28Cとセンタバッグ部28の助手席側の側部28Aとを連結しており、オブリーク拘束時の第二ベントホール28Hからのガス排気量を正突拘束時よりも絞るように構成されている。【選択図】図1
