To obtain a seat cushion of a vehicle seat which can support an occupant in a stable state when an external force is exerted on the occupant in a seat width direction.SOLUTION: A seat cushion of a vehicle seat includes: a support mechanism which holds a pan frame 42 in an initial state where a left part and a right part are located at the same height when an external force is not exerted on the pan frame and allows rotation of the pan frame around a first rotation shaft 27 when the external force is exerted; a cushion pad 60 which is provided at the pan frame and side frames 45, 50 and forms side support parts 62 where a portion provided at the side frame is located at a higher level than a portion provided at the pan frame; and a side part control mechanism which rotates one of the side frames around a second rotation shaft so that the one side frame facing one of the left part and the right part moves close to the other side frame facing the other when the pan frame rotates so that the one of the left part and the right part is located lower than the other.SELECTED DRAWING: Figure 5

    【課題】乗員にシート幅方向の外力が及んだときに乗員を安定した状態で支持できる車両用シートのシートクッションを得る。【解決手段】パンフレーム42に外力が付与されないとき、パンフレームを左側部及び右側部が同じ高さになる初期状態に保持し且つ外力が付与されたときにパンフレームが第1回転軸27回りに回転するのを許容する支持機構と、パンフレーム及びサイドフレーム45、50に設けられ且つサイドフレームに設けられた部位がパンフレームに設けられた部位よりも上方に位置する側方支持部62を構成するクッションパッド60と、左側部と右側部の一方が他方より下方に位置するようにパンフレームが回転したときに、一方と対向する一方のサイドフレームが他方と対向する他方のサイドフレームに接近するように、一方のサイドフレームを第2回転軸回りに回転させる側部制御機構と、を備える。【選択図】図5
