PROBLEM TO BE SOLVED: To provide a seat capable of properly switching a seat surface part between a state corresponding to a perching posture and a state corresponding to a sitting posture.SOLUTION: A seat 1 having a seat surface part 3 serving as a stool for a seated person P has a switching mechanism 10 that can forwardly unfold down or backwardly fold up the seat surface part by turning the seat surface part relative to a floor surface F. With the switching mechanism 10, the seat surface part 3 can be switched between a forward-unfolded posture 3D in which the seat surface part is forwardly unfolded down so that a first support surface 3A facing upward comes into a state at a low position where the seated person P can lower his or her body to sit thereon, and a second support surface 3B facing frontward comes into a state in which the second support surface forms a backwardly inclined surface that is inclined backwardly downward, and a folded-up posture 3U in which the seat surface part is folded up backward from the forward-unfolded posture 3D so that a second support surface 3B is lifted up at a higher position than the position of the first support surface 3A in the forward-unfolded posture 3D, and an upper surface inclined forwardly downward is formed by the backwardly inclined surface so that the second support surface comes into a state at the high position where the seated person P can perch thereon in the standing posture.SELECTED DRAWING: Figure 5
【課題】座面部を立座り姿勢に対応した状態と座込み姿勢に対応した状態とに適切に切り換えられるようにすること。【解決手段】着座者Pの腰掛けとなる座面部3を床面Fに対して回転により前側に倒し込んだり後側に跳ね上げたりすることのできる切換機構10を有する座席1である。切換機構10により、座面部3が、前側に倒し込まれてその上側に向けられる第1の支持面3Aを着座者Pが腰を落として座り込むことのできる低位置の状態にすると共にその前側に向けられる第2の支持面3Bを後下がり状に引いた引き込み面を形成する状態にする前倒し姿勢3Dと、前倒し姿勢3Dから後側に跳ね上げられて第2の支持面3Bを前倒し姿勢3Dにおける第1の支持面3Aよりも高い位置に引き上げると共に引き込み面により前下がり状に傾斜した上面を成して着座者Pが立ち姿勢で腰掛けることのできる高位置の状態にする跳ね上げ姿勢3Uとに切り換えられる。【選択図】図5
