PROBLEM TO BE SOLVED: To provide an airbag device for a front seat including an airbag which can deploy and expand in an L-shape from a storage portion when viewed from above by suppressing interference with surrounding members in the storage portion.SOLUTION: An airbag 61 for a front seat of an airbag device for a front seat includes: a gas inflow part 62 for allowing a gas for expansion to flow in; and a bag body part 70 for connecting a front end part 71 to a left side of the gas inflow part. In the gas inflow part 62, outer peripheral edges of a ceiling wall part 66 of an upper surface side and a bottom wall part 63 of a lower surface side, whose outer shapes are made to be substantially the same, are connected with each other, an opening 64 for inflow opening for allowing the gas for expansion to flow in is provided at the bottom wall part, and a peripheral edge of the opening for inflow is made to be a mounting part 65 to a storage portion. In the front end part 71 of the bag body part, a front edge 71a side is connected to a front edge 62a of the gas inflow part, and the front end part continues to a body expansion part 72 at the back by having an expansion shape in which a thickness dimension from the front edge 71a side toward the back gradually increases.
【課題】収納部位での周囲の部材との干渉を抑制して、上方から見て収納部位からL字形に展開膨張可能なエアバッグを備えた前席用エアバッグ装置の提供。【解決手段】前席用エアバッグ装置の前席用エアバッグ61は、膨張用ガスを流入させるガス流入部62と、ガス流入部の左方側に前端部71を連結させるバッグ本体部70と、を備える。ガス流入部62は、外形形状を略等しくした上面側の天井壁部66と下面側の底壁部63との外周縁相互を結合させ、底壁部に膨張用ガスを流入させために開口する流入用開口64を備えて、流入用開口の周縁を収納部位への取付部65とする。バッグ本体部の前端部71は、前縁71a側をガス流入部の前縁62aと連ならせ、かつ、前縁71a側から後方に向かった厚さ寸法を漸増させる膨張形状として、後方の本体膨張部72に連なる。【選択図】図3
