The utility model relates to a rising auxiliary chair (1), which comprises a movable seat and an adjusting mechanism, the adjusting mechanism comprises a bearing base, at least a positioning element, at least a first rotating part, at least a first adjusting part, at least a second rotating part, and at least a second adjusting part pivoted on the second rotating part, wherein the first adjusting part comprises a first extension The second adjusting member comprises a second extension section and a second bending section.By means of the above structure, the initial position of the first rotating part is higher than the second rotating part, so as to free up the space of moment action, and the force application point of the power assembly acts on the first bending section and the second bending section of the long arm, so as to reduce the demand of the force, improve the stability of the action, and reduce the action range and make the seat rise in parallel by the synchronous action of the two adjusting parts.本新型為有關一種起身輔助椅(一)，係包含一活動座椅及一調整機構，該調整機構包含：一承載基座、至少一定位元件、至少一第一旋轉部、至少一第一調節件、至少一第二旋轉部、及至少一樞設於該第二旋轉部上之第二調節件，其中該第一調節件包含一第一延伸段及一第一彎折段，且該第二調節件包含一第二延伸段及一第二彎折段。藉上述結構，讓第一旋轉部的初始位置高於第二旋轉部，以騰出力矩作用空間，讓動力組件的施力點作用於力臂較長的第一彎折段與第二彎折段，以降低作用力之需求，提升動作穩定度，並藉兩調節件的同步作動，降低動作幅度，讓座椅平行上升。
