PROBLEM TO BE SOLVED: To restrain a head of an occupant when impact load is applied on a vehicle from obliquely in front of the vehicle.SOLUTION: An airbag device 10 includes: a gas generator 14 that is actuated to generate gas; and an airbag 16 that is disposed in a vehicle, in front of a vehicle seat where an occupant sits, and into which gas generated by the gas generator 14 is supplied, thus inflating the airbag. The airbag 16 includes: a center chamber portion 18; a left chamber portion 20 and a right chamber portion 22 that are disposed laterally adjacent to the center chamber portion 18, and a boundary line between each of which and the inflated center chamber portion 18 is laterally offset from a bisector L laterally bisecting the vehicle seat; and a left tether 28 and a right tether 30 for laterally tying upper portions in the vehicle, of the center chamber portion 18, the left chamber portion 20, and the right chamber portion 22 that are inflated, to one another.SELECTED DRAWING: Figure 1

    【課題】車両斜め前方側からの衝突荷重が車両に加わった際に乗員の頭部を拘束する。【解決手段】エアバッグ装置10は、作動することでガスを発生させるガス発生装置14と、乗員が着座する車両用シートの車両前方側に配置され、ガス発生装置14により発生されたガスが内部に供給されることで膨張されるエアバッグ16と、を備えている。エアバッグ16は、センタチャンバ部18と、センタチャンバ部18と車幅方向に隣り合って配置されかつ膨張されたセンタチャンバ部18との境目が車両用シートを車幅方向に二等分する二等分線Lに対して車幅方向にオフセットして配置された左側チャンバ部20及び右側チャンバ部22と、膨張されたセンタチャンバ部18、左側チャンバ部20及び右側チャンバ部22の車両上方側の部位を車幅方向に繋ぐ左側テザー28及び右側テザー30と、を備えている。【選択図】図1
