One kind is stood up the composed structure of auxiliary chair, is that seat, the chair back set in the what chair frame by a chair frame and group forms, and sets a power source below the what seat, when which starts through one first control-rod, the seat can be driven to rise or fall. Main system is by the seat front end with the chair frame pivot group ining conjunction with, then what chair frame lower section is equipped with a locating rack, sets the power source using a pivot group unit group between the locating rack and the seat, and the pivot group unary system sets what and corresponds to the seat Hou side and suitably locates. The axle bed of one end is pivoted on the what locating rack by the pivot group unary system, what seat back side and the stacker of another end is then pivoted, power source one end group is enabled to set the what axle bed accordingly, the line shaft of the scalable actuation of another end then connects with the stacker group, when the power source rises actuation, the seat can be enabled using the position of front end pivot group as axle center, make the rising at an angle of Hou side, to jack up user, reach the purpose that auxiliary is stood up.一種起身輔助椅之組成結構,係由一椅架,以及組設於該椅架上之椅座、椅背組成,並於該椅座下方設一動力源,該動力源透過一第一控制桿啟動時,可帶動該椅座上升或下降。主要係將該椅座前端與該椅架樞組結合,再於該椅架下方設有一定位架,該定位架及該椅座之間利用一樞組單元組設該動力源,且該樞組單元係設於對應該椅座後方適當處。該樞組單元係將一端之軸座樞設於該定位架上,而另端之承接座則樞設於該椅座背面,據以令該動力源一端組設於該軸座,另端可伸縮作動之動力軸則與該承接座組接,當該動力源上升作動時,可令該座椅以前端樞組之部位為軸心,使後方呈一傾斜角度上升,用以將使用者頂起,達到輔助起身之目的。
