To provide a vehicular airbag device that can be improved in performance of restraining the head of an occupant at the time of a front collision of a vehicle.SOLUTION: An outer airbag 12 and an inner airbag 14 of a vehicular airbag device 10 are stored inside a seat back 24 of a vehicular seat 20, and receives supply of gas from an inflator 30 to inflate and expand when predicting or when sensing a front side collision. The outer airbag 12 inflates and expands from a lateral of one side of the head H of an occupant P prior to the inner airbag and is folded back into a V-shape toward a front of a seat by a shape holding Tether 18 in a planar view. The inner airbag 14 is inflated and expanded from the lateral of the one side of the head H of the occupant P, at the opposite side of the outer airbag 12, and is folded back in the same manner as the outer airbag 12 is folded back and is held from the outside by the outer airbag 12, so that the inner airbag 14 in an inflated and expanded state is arranged to cover the front side of the head H of the occupant P to directly restrain the head H.SELECTED DRAWING: Figure 1

    【課題】車両の前面衝突時における乗員の頭部拘束性能を向上させることができる車両用エアバッグ装置を得る。【解決手段】車両用エアバッグ装置10の外側エアバッグ12及び内側エアバッグ14は、車両用シート20のシートバック24の内部に収容され、前面衝突の予知時又は検知時にインフレータ30からガスの供給を受けて膨張展開する。外側エアバッグ12は、内側エアバッグに先行して乗員Pの頭部Hの片側の側方から膨張展開し、形状保持テザー18によって平面視でシート前方に向かってV字状に折り曲げられる。内側エアバッグ14は、外側エアバッグ12の反対側で乗員Pの頭部Hの片側の側方から膨張展開され、外側エアバッグ12と同様に折り曲げられると共に外側エアバッグ12によって外側から保持される。これにより、内側エアバッグ14は、膨張展開状態で乗員Pの頭部Hの前方を覆うように配置され、頭部Hを直接拘束する。【選択図】図1
