To provide an occupant protection device configured so as to allow an airbag to quickly complete inflation thereof and to be able to secure stable reaction force when receiving an occupant.SOLUTION: The occupant protection device comprises an airbag 20 in an approximately triangular and annular shape in which are arranged a first inflation part 27 that protrudes rearward from a storage site 12 arranged in a vehicle body-side member 2 and is supported by the vehicle body-side site around a hollow part 32 and a second inflation part 25 that extends rearward from the first inflation part, during inflowing of gas for inflation, and a third inflation part 29 that connects a rear end 25b of the second inflation part to the first inflation part 27. For the second inflation part 25 of the airbag, the vicinity of the rear end 25b is set as a site, arranged at a rearmost end of the airbag, at which a head H of an occupant OP that moves forward is received when inflation is completed, and the vicinity of the rear end 25b is supported by the third inflation part 29 to be compression-deformable so that the rear end 25b side is made to approach a front end 25a side, when receiving the head, and further the vicinity of the rear end 25a is connected to the first inflation part 27 so that reaction force from the vehicle body-side site 2 can be secured.SELECTED DRAWING: Figure 1
【課題】エアバッグが、迅速に膨張を完了させることができ、かつ、乗員受止時に安定した反力を確保できる乗員保護装置を提供すること。【解決手段】膨張用ガスの流入時、車体側部材2に配設された収納部位12から後方へ突出して、中空部32の周囲で、車体側部位に支持される第1膨張部27と、第1膨張部から後方に延びる第2膨張部25と、第2膨張部の後端25bと第1膨張部27とを連結する第3膨張部29と、を配設させた略三角環状のエアバッグ20を備える。エアバッグの第2膨張部25は、膨張完了時、後端25b付近を、エアバッグの最後端に配置させて、前方移動する乗員OPの頭部Hの受止部位とし、受止時に、後端25b側を前端25a側に接近させるような圧縮変形可能に、後端25b付近を、第3膨張部29に支持させ、かつ、車体側部位2からの反力を確保可能に、前端25a付近を、第1膨張部27に連結させている。【選択図】図1
