To inhibit a seat part from collapsing forward during a vehicle collision.SOLUTION: A vehicle seat 1 includes: an upper frame 20 on which a seat part 10 is placed; a lower frame 22 provided on a floor surface 3 and facing the upper frame 20; a link mechanism 24 which couples the upper frame 20 to the lower frame 22 and adjusts a position of the upper frame 20 relative to the lower frame 22; a belt member 30 coupled to the rear side of the upper frame 20 at one longitudinal end side and having a deformation part 32 which loosens; and a tension mechanism 50 which pulls the other longitudinal end side of the belt member 30 to stretch the loosened deformation part 32 during a vehicle collision.SELECTED DRAWING: Figure 1 【課題】車両衝突時にシート部が前方に倒れることを抑制する。【解決手段】車両用シート１は、シート部１０が載置される上部フレーム２０と、床面３に設けられ、上部フレーム２０に対向している下部フレーム２２と、上部フレーム２０と下部フレーム２２とを連結し、下部フレーム２２に対する上部フレーム２０の位置を調整するリンク機構２４と、長手方向の一端側が上部フレーム２０の後方側に連結されており、弛みとなる変形部３２を有するベルト部材３０と、車両衝突時にベルト部材３０の長手方向の他端側を引っ張り、弛んだ変形部３２を伸ばす引っ張り機構５０と、を備える。【選択図】図１
