To restrict forward movement of a lumbar part of a crewman irrespective of a seating posture of the crewman.SOLUTION: A seat cushion airbag device 40 is applied to a vehicle seat comprising a cushion part 12 on which a crewman sits. The airbag device 40 comprises an air bag 50 between the cushion part 12 and a support part 31, which is located on a lower side of the cushion part 12, and at a central part in a width direction of the vehicle seat. The airbag device 40 inflates the air bag 50 by a gas for inflation supplied from a gas generator 41, thereby restricting forward movement of a lumbar part of the crewman. A fastening part for fastening the air bag 50 to the support part 31 is configured by the gas generator 41 and a nut 45. The gas generator 41 and the nut 45 fasten the air bag 50 to the support part 31 in the rear of a lower part of the air bag 50 in an inflated state with respect to a midship part in a cross direction.SELECTED DRAWING: Figure 2

    【課題】乗員の着座姿勢に拘わらず腰部の前方への移動を規制する。【解決手段】シートクッションエアバッグ装置40は、乗員が着座するクッション部12を備える車両用シートに適用される。エアバッグ装置40は、クッション部12と、同クッション部12の下側に配置された支持部31との間であって、車両用シートの幅方向における中央部分にエアバッグ50を備える。エアバッグ装置40は、ガス発生器41から供給される膨張用ガスによりエアバッグ50を膨張させることで、乗員の腰部の前方への移動を規制する。エアバッグ50を支持部31に締結するための締結部は、上記ガス発生器41及びナット45によって構成される。ガス発生器41及びナット45は、膨張状態のエアバッグ50の下部のうち、前後方向における中央部よりも後方で、エアバッグ50を支持部31に締結する。【選択図】図2
