To provide an occupant protection device configured so that an airbag expanding and inflating downward from a roof side can stably receive and protect the head of an occupant.SOLUTION: An occupant protection device comprises an airbag 16, stored in a roof 4 side at a front and upper side of an occupant OP seated in a vehicle 1, which expands and inflates downward when gas G for inflation flows into the airbag and protectably receives the head H of the occupant who moves forward at the time of a collision of the vehicle. The airbag completely inflating comprises a base inflation part 18 extending downward from a storage site 12, and a receiving inflation part 24 which protrudes rearward from the base inflation part and has the vicinity of a rear end surface 24a as a receiving surface for the head of the occupant. The base inflation part comprises a main body inflation part 20 that extends downward in a columnar shape from the storage site to protrude the receiving inflation part rearward, and a support inflation part 22 that protrudes toward the front side of the main body inflation part to make a vehicle body-side member 8 arranged at a peripheral edge in front of the storage site support an upper surface 22a side to restrict the main body inflation part from moving forward.SELECTED DRAWING: Figure 2
【課題】ルーフ側から下方に展開膨張したエアバッグが、安定して、乗員の頭部を受け止めて保護できる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の前上方のルーフ4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、車両衝突時に前方移動する乗員の頭部Hを保護可能に受け止めるエアバッグ16、を備える。膨張完了時のエアバッグは、収納部位12から下方へ延びる基部膨張部18と、基部膨張部から後方側に突出して、後端面24a付近を乗員の頭部の受止面とする受止膨張部24と、を備える。基部膨張部が、収納部位から下方に柱状に延びて、受止膨張部を後方側へ突出させる本体膨張部20と、本体膨張部の前方側に突出して、収納部位の前方側の周縁に配置された車体側部材8に、上面22a側を支持させて、本体膨張部の前方移動を規制する支持膨張部22と、を備える。【選択図】図2
