To provide an occupant protection device that, in the event of vehicle collision, is able to accurately receive an occupant in a stable position such that his or her chest is directed in a forward and upward direction with the backrest of a seat reclined backward.SOLUTION: An occupant protection device comprises an air bag 16 that is accommodated on a roof 6 side above a seated occupant OP in a vehicle 1, inflates and expands downward when expansion gas G flows in, and in the event of vehicle collision, receives the occupant OP in a stable position such that a backrest 4a of a seat 4 is reclined backward with his or her chest B directed in a forward and upward direction. The air bag comprises: a basal part 17 extending downward from an accommodated position 12 when expansion is completed; and an occupant receiving part 18 that is disposed on a basal-part lower end 17b side. The occupant receiving part comprises: a chest receiving surface 19 disposed on a rear-end lower surface side of the occupant receiving part and extending in an obliquely rear and downward direction opposite the occupant chest B, thereby making it possible to receive the chest; and a head receiving surface 20 disposed on a rear-end upper surface side of the occupant receiving part and extending in an obliquely rear and upward directions so as to continue from an upper end 19a side of the chest receiving surface, thereby making it possible to receive a head H of the occupant.SELECTED DRAWING: Figure 4
【課題】シートの背もたれ部を後傾させて胸部を前上方向に向けた安楽姿勢の乗員を、車両衝突時に、的確に受止可能な乗員保護装置を提供すること。【解決手段】車両1における着座した乗員OPの上方のルーフ6側に収納されて、膨張用ガスGの流入時に下方に展開膨張し、シート4の背もたれ部4aを後傾させて胸部Bを前上方向に向けた安楽姿勢の乗員OPを、車両衝突時に保護可能に受け止めるエアバッグ16、を備える。エアバッグは、膨張完了時に、収納部位12から下方へ延びる基部17と、基部下端17b側に配設される乗員受止部18と、を備える。乗員受止部は、乗員受止部の後端下面側に配設されて、乗員胸部Bに対向する斜め後下向きとして、胸部を受止可能な胸部受止面19と、乗員受止部の後端上面側に配設されて、胸部受止面の上縁19a側から連なるように、斜め後上向きとして、乗員の頭部Hを受止可能な頭部受止面20と、を備える。【選択図】図4
