To suppress twisting of right and left side parts of a backrest frame in vehicle collision while achieving reduction in weight and thickness of the backrest frame.SOLUTION: A vehicle sheet 1 includes: a resin backrest frame 40 of a backrest part 11; and a non-flexible string-shaped member 70 which connects right and left side parts 50 of the backrest frame 40 in a state where a tension is applied. In the string-shaped member 70, a central region 80 in a longitudinal direction of the string-shaped member 70 is arranged between right and left ends 50 of the backrest frame 40, and is wound around side parts 50 of the backrest frame 40 so as to pass through a back surface 50a and an outside surface 50b of the right and left side parts 50 of the backrest frame 40 in this order from the central region 80 toward both ends 100, and ends 100 of the string-shaped member 70 are fixed to each other in the center in the right and left direction of the backrest frame 40.SELECTED DRAWING: Figure 4

    【課題】背凭れフレームの軽量化及び薄型化を図りつつ、車両衝突時の背凭れフレームの左右の側部の捻じれを抑制する。【解決手段】車両用シート1は、背凭れ部11の樹脂製の背凭れフレーム40と、張力が付加された状態で、前記背凭れフレーム40の左右の側部50同士を接続する非伸縮性の紐状部材70と、を備えている。紐状部材70は、その紐状部材70の長手方向の中央領域80が背凭れフレーム40の左右の端部50の間に配置され、中央領域80から両端部100に向けて、背凭れフレーム40の左右の側部50の背面50a及び外側面50bをこの順番で通るように背凭れフレーム40の側部50に巻き付けられ、背凭れフレーム40の左右方向の中央で紐状部材70の端部100同士が固定されている。【選択図】図4
