A kind of auxiliary uprisal device,It is mainly to drive linear bearing slide bar that longitudinal passage is done in the sliding push plate of two opposite support high trestles through driving source,And enable the two high seating pads of support being pivotally connected respectively with grade sliding push plate that the cushion of seat is driven to push up,And prop up user,And during what props up user,The direction inclined by using person's body forward and the weight of user is caused to be intended to stand to user deviates and falls the leading edge of what cushion,And so that the grade is supportted high seating pad to be pivotally connected the pivot points axis rotation that grade slides push plate,So that cushion generates an angle passage during upward passage,And effectively user is assisted to stand.一種輔助起身裝置，其主要係透過驅動源帶動線性軸承滑桿將二相對的撐高支架之滑動推板做縱向推移，而令與該等滑動推板分別樞接之二撐高坐墊板帶動座椅之坐墊向上推，而將使用者撐起，並於將使用者撐起之過程中，藉由使用者身體向前傾而造成使用者之重量向使用者欲站起之方向偏移並落於坐墊之前緣，而使該等撐高坐墊板以樞接於該等滑動推板之樞接位置為軸心轉動，以使坐墊在向上推移的過程中產生一角度推移，而有效輔助使用者站起。
