PROBLEM TO BE SOLVED: To obtain a seat for a vehicle mounted with a side airbag device which can alleviate a load to a rear lower part of a rib of a seated occupant while securing the constriction performance of the seated occupant.SOLUTION: A first webbing 70 is arranged at a side part 16A of a seatback 16 at the outside of a vehicle width direction along a rear surface of an outside Fr-side skin 36. The first webbing 70 is arranged at a height position corresponding to a height of a rear lower part of a rib of a seated occupant P, and extended in a band shape in a vehicle fore-and-aft direction in a vehicle side view. The first webbing 70 comprises a region 70X which is arranged at a side opposite to the rear lower part of the rib of the seated occupant P, and constituted so as to be difficult to elongate longer than the outside Fr-side skin 36. Both end parts 70A, 70B of the first webbing 70 when viewed from a height direction of the seatback 16 are attached into the seatback 16 so that the displacement of the first webbing 70 is limited at the expansion and deployment of a breast rear-side constriction part 60C.SELECTED DRAWING: Figure 2
【課題】着座乗員の拘束性能を確保しながら着座乗員の肋骨後下部への負荷を低減することができるサイドエアバッグ装置を搭載した車両用シートを得る。【解決手段】シートバック16の車両幅方向外側の側部16Aには、外側Frサイド表皮36の裏面に沿って第一力布70が配置されている。第一力布70は、着座乗員Pの肋骨後下部の高さに相当する高さ位置に設けられて車両側面視で車両前後方向に帯状に延びている。第一力布70は、着座乗員Pの肋骨後下部と対向する側に配置される部位70Xを備え、外側Frサイド表皮36よりも伸び難く構成されている。シートバック16の高さ方向から見た場合の第一力布70の両端部70A、70Bは、胸部後側拘束部60Cの膨張展開時に第一力布70の変位が制限されるようにシートバック16内に取り付けられている。【選択図】図2
