To restrain an occupant seated on a center part of a rear seat stably when a collision with a vehicle occurs.SOLUTION: A rear seat airbag 10 expands and deploys from a lower part of a center console 2 of a vehicle to a center part of a rear seat and includes: a first airbag 20 which restrains an upper half body of an occupant CR seated on the center part of the rear seat; and a second airbag 30 which retrains a lower half body of the occupant CR seated on the center part of the rear seat. When the rear seat airbag 10 expands and deploys, the first airbag 20 is coupled to the second airbag 30 so as to cover more than half of the second airbag 30. A centroid of the first airbag 20 and the second airbag 30 coupled to each other becomes an intersection point of virtual locus of a head HE, a chest CH, and a knee KN of the occupant CR seated on the center part of the rear seat which are moved forward by an impact caused by a collision of the vehicle.SELECTED DRAWING: Figure 2

    【課題】車両への衝突発生時において、後席中央部に着座する乗員を安定して拘束する。【解決手段】車両のセンターコンソール2下部から、後席中央部に膨張展開する後席用エアバッグ10であって、後席中央部に着座する乗員CRの上半身を拘束する第1のエアバッグ20と、後席中央部に着座する乗員CRの下半身を拘束する第2のエアバッグ30と、を備え、膨張展開時に、第1のエアバッグ20は、第2のエアバッグ30の半分以上を覆うように、第2のエアバッグ30と結合され、結合された第1のエアバッグ20と第2のエアバッグ30の重心は、車両の衝突によって生じる衝撃により、後席中央部に着座する乗員CRの頭部HE、胸部CH、膝部KNが前方移動する仮想軌跡の交点となる。【選択図】図2
