PROBLEM TO BE SOLVED: To improve fatigue of an inferior limb of a person who has seated on a seat during an extended period.SOLUTION: A recess 5a is provided on a floor 5 near the front side of a sofa 1, a lifting mechanism 25 which is configured from an X link mechanism and a movable floor 21 which is lifted by the lifting mechanism 25 are accommodated in the recess 5a. When a person 7 seating on the sofa 1 operates an elevation switch 71, an actuator 53 is driven, whereby the movable floor 21 is elevated from a "storage position" at which the movable floor is stored in the recess 5a to an "elevated inclined position" at which a front part of the movable floor is so inclined as to be positioned at a position higher than that of a rear part thereof.SELECTED DRAWING: Figure 1
【課題】シートに人が長時間着座したときの下肢の疲労を改善する。【解決手段】ソファ1の前方側近傍のフロア5に凹部5aが設けられ、凹部5aに、Xリンク機構で構成される昇降機構25及び、昇降機構25によって昇降する可動フロア21を収容する。ソファ1に着座している人7が昇降スイッチ71を操作すると、アクチュエータ53が駆動して、可動フロア21が凹部5aに格納される「格納位置」から上昇し、前部が後部よりも高い位置となるよう傾斜した「上昇傾斜位置」となる。【選択図】図1
