PROBLEM TO BE SOLVED: To provide a posture change operation support structure of a vehicle seat which is suitable for reducing operational ability during posture change of a seat while suppressing increase in a cost and a weight thereof.SOLUTION: A posture change operation support structure of a vehicle seat, of which a posture can be changed between a use position at which the seat is located on a deck 20 and a storage position at which the seat is stored on the floor 30 which is present forwards and at a lower position with respect to the deck 20, comprises a torsion spring 50 which is so provided as to extend in a width direction of a seat 10. One end side of the torsion spring 50 is attached to a rear lower part of the seat 10, and a portion thereof extended on the other end side is attached to the floor 30 side. The torsion spring 50 is positioned at a neutral position when the seat 10 is positioned at a prescribed position between the use position and the storage position, and gives a resilient force onto the seat 10 so that the seat 10 returns to the neutral position when the seat is positioned at either the use position or the storage position.SELECTED DRAWING: Figure 3

    【課題】コスト高や重量増加を抑制しつつ、シートの姿勢変更時の操作力を低減するのに適した車両用シートの姿勢変更操作ポート構造を提供すること。【解決手段】デッキ20上に配置される使用位置と、デッキ20より前方でかつ低位置にあるフロア30上に収納される収納位置と、の間で姿勢変更可能な車両用シートにおける姿勢変更操作のサポート構造であって、シート10の幅方向に延びるように配設されたトーションスプリング50を備え、トーションスプリング50は、一端側がシート10の後部下へ取り付けられ、他端側において延設された部分がフロア30側に取り付けられる。トーションスプリング50は、シート10が使用位置と収納位置との間の所定位置にあるときに中立位置をとり、シート10が使用位置および収納位置のいずれの位置にあるときも中立位置に戻るようにシート10に弾発力を与える。【選択図】図3
