PROBLEM TO BE SOLVED: To provide a front passenger seat airbag apparatus configured to be able to protect a passenger not only during a front collision but also during a vehicle oblique collision or an offset collision, and capable of being smoothly inflated while detouring a protruding object protruding from an instrument panel.SOLUTION: An airbag 15 comprises a main body inflation part 17; and a protruding inflation part 35, a passenger protection part 40 on a rear surface side at a time of completing inflation comprises a front collision constraint surface 41; an oblique collision constraint surface 42; and a constraint recessed part 43 between the front collision constraint surface 41 and the oblique collision constraint surface 42. In the main body inflation part 17, a supporting inflation part 26 that can support a front side of the protruding inflation part 35 is formed such that a detour recessed part 27 capable of detouring a protruding object 3 protruding upward from an instrument panel 1 is provided in an area on the front side of the protruding inflation part 35. In the main body inflation part 17, a horizontal tether 57 is disposed generally along a horizontal direction to be able to restrict an inflation shape of a region near the detour recessed part 27.SELECTED DRAWING: Figure 19
【課題】前面衝突時に加えて、車両の斜め衝突時若しくはオフセット衝突時にも乗員を保護可能な構成のエアバッグであっても、インストルメントパネルから突出する突出物を迂回して円滑に膨張可能な助手席用エアバッグ装置の提供。【解決手段】エアバッグ15が、本体膨張部17と突出膨張部35とを備えるとともに、膨張完了時の後面側の乗員保護部40を、前突用拘束面41と、斜突用拘束面42と、前突用拘束面41と斜突用拘束面42との間の拘束用凹部43と、を備える構成としている。本体膨張部17において、突出膨張部35の前側の領域に、インストルメントパネル1から上方に突出する突出物3を迂回可能な迂回用凹部27を設けるようにして、突出膨張部35の前側を支持可能な支持膨張部26が、形成される。本体膨張部17内に、迂回用凹部27付近の部位の膨張形状を規制可能に、左右テザー57が、左右方向に略沿って配置される。【選択図】図19
