PROBLEM TO BE SOLVED: To provide an electric lifting chair that can inhibit users fingers from being pinched by the movable part of the electric lifting chair or a structure other than the electric lifting chair when the seat plate is lifted and lowered.SOLUTION: The electric lifting chair 1 includes: a base frame 2 an elevating/lowering body (elevation body) 3 which is held in a freely elevating/lowering manner on the base frame 2 and an electric actuator which elevates/lowers the elevation body 3. In the elevation body 3, there are provided a seat plate 12 and a pair of left/right arm rests 13. In the under side of the tip end part of the pair of left/right arm rests 13, there are installed left and right respectively lever switches 14A, 14B for elevating the elevation body 3 by operating the electric actuator, so that the end parts as the tip end side of the arm rests 13 can be oscillated vertically. Only when the lever switches 14A, 14B are oscillated upward in both left and right, the elevation body 3 is elevated and, only when the lever switches 14A, 14B are oscillated downward in both left and right, the elevation body 3 is lowered.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】座板の昇降時に使用者の手指が電動昇降椅子の可動部や電動昇降椅子以外の構造物に挟まれることを抑制することができる電動昇降椅子を提供する。【解決手段】電動昇降椅子1は、ベースフレーム2と、ベースフレーム2に昇降自在に支持された昇降体3と、昇降体3を昇降させる電動アクチュエータとを備えているとともに、昇降体3には、座板12と左右一対の肘掛け13とが設けられており、左右一対の肘掛け13の先端部下面には、電動アクチュエータを操作して昇降体3を昇降させるためのレバースイッチ14A,14Bが、肘掛け13の先端側となる端部を上下方向へ揺動させることができるように、左右それぞれに取り付けられており、レバースイッチ14A,14Bを左右共に上方向へ揺動させた場合に限って昇降体3が上昇し、レバースイッチ14A,14Bを左右共に下方向へ揺動させた場合に限って昇降体3が下降する。【選択図】図1
