To suppress a head part from moving forward to improve occupant protection performance.SOLUTION: An airbag 41 of an airbag device 40 is housed in a housing part 35 provided in one side part 15 in a width direction, of a seat back 13. When an impact is applied to a vehicle from a front side of a vehicular seat 11, the airbag 41 is supplied with gas for inflation to inflate toward a side of a headrest 16 while leaving a portion thereof in the housing part 35. A portion of the airbag 41 protruding from the housing part 35 expands and inflates toward a rear side of the seat back 13, and further expands and inflates toward a side get away from the housing part 35 in the width direction, behind the headrest 16. Another portion of the airbag 41 protruding from the housing part 35 expands and inflates toward a front side of the seat back 13, and further expands and inflates so as to wind around a head PH of an occupant P1, so as to get away from the housing part 35 in the width direction, in front of the head PH.SELECTED DRAWING: Figure 2

    【課題】頭部の前方への移動を抑制して、乗員保護性能を高める。【解決手段】エアバッグ装置40のエアバッグ41は、シートバック13のうち、幅方向における一方の側部15内に設けられた収納部35に収納される。エアバッグ41は、車両用シート11の前方から車両に衝撃が加わった場合に、膨張用ガスが供給されて膨張し、自身の一部を収納部35に残した状態で、ヘッドレスト16の側方へ出る。収納部35から出たエアバッグ41の一部は、シートバック13の後方へ展開及び膨張し、ヘッドレスト16よりも後方で、上記幅方向のうち収納部35から遠ざかる側へ向けて展開及び膨張する。収納部35から出たエアバッグ41の別の一部は、シートバック13の前方へ展開及び膨張し、乗員P1の頭部PHよりも前方で、上記幅方向のうち収納部35から遠ざかる側へ向けて、頭部PHに巻き付くように展開及び膨張する。【選択図】図2
