PROBLEM TO BE SOLVED: To provide a vehicle seat with a seat belt in which a seat back is prevented from being bent forward in the front surface collision of the vehicle, while preventing mass increase and degradation of design flexibility of the vehicle seat, in the vehicle seat with the seat belt equipped with a side air bag.SOLUTION: A lower surface 50 of a side air bag 40 expanded and developed from the side of a vehicle width direction outside of a seat back 14 comes in abutment with an upper surface 18A of a sheet side shield 18 and an upper surface 13A of a side part 13 on the occurrence of head-on collision of a vehicle, and thereby reaction force is input from the sheet side shield 18 and a seat cushion 12. The side air bag 40 where this reaction force is input supports the seat back 14, and thereby the seat back 14 is prevented from being bent forward on the occurrence of the head-on collision of the vehicle. Namely, the forward tilting of the seat back 14 can be prevented while preventing the degradation of design flexibility and the mass increase of a vehicle seat 10.SELECTED DRAWING: Figure 2

    【課題】サイドエアバッグを搭載したシートベルト付き車両用シートにおいて、車両用シートの質量増加及び設計自由度の低下を抑制しつつ、車両の前面衝突時にシートバックが前傾することを抑制するシートベルト付き車両用シートを提供する。【解決手段】車両が前面衝突した際、シートバック14の車幅方向外側側部から膨張展開されたサイドエアバッグ40の下面50がシートサイドシールド18の上面18Aとサイド部13の上面13Aに当接(押圧)することによって、シートサイドシールド18及びシートクッション12から反力が入力される。この反力が入力されたサイドエアバッグ40がシートバック14を支持することにより、車両の前面衝突時にシートバック14が前傾することが抑制される。すなわち、車両用シート10の設計自由度の低下と質量増加を抑制しつつ、シートバック14の前傾を抑制することができる。【選択図】図2
