As the backrest is gradually displaced in the laying direction, the front of the front seat part gradually becomes higher than the rear seat part, and when the backrest is laid approximately to the intermediate point of the whole lying angle, the front of the front seat part becomes highest. As the backrest is further laid down, the front of the front seat part gradually becomes lower, and when the backrest is laid to the final position, the front seat part is in the flat state with the rear seat part.COPYRIGHT: (C)2010,JPO&INPIT【課題】4時間にもおよぶ人工透析治療に苦痛を感じさせない椅子を提供する。【解決手段】背凭れ4が最大の起立位置において座部2における後部座部2aと前部座部2bとがフラット状態であり、前記背凭れを伏倒方向に変位させるに伴って前部座部が後部座部に対して徐々に前部座部の前方が高くなり、背凭れを全寝角度の略中間地点まで伏倒させると前記前部座部の前方が最大限まで高くなり、さらに背凭れを伏倒するに従って前記前部座部の前方が徐々に低くなり、背凭れが最終位置まで伏倒すると前記前部座部は後部座部とフラット状態となる人工透析用椅子である。【選択図】図4
