Problem to be Solved: To provide a compact and lightweight standing assistance equipment which can be easily and universally mounted to various types of furniture to assist a standing-up motion of a user. Solution: A standing assistance equipment has a seating surface 1 joined to a base 2 through a hinge 3 to be movable in an open positon and a closed position with respect to the base 2. At least one double torsion spring 6a, at least one torsion coil spring 6b, and at least one gas spring 4 are arranged in between the seating surface 1 and the base 2 to slant the seating surface 1 upward towards its rear side. A pair of the double torsion spring 6a and the torsion coil spring 6b are arranged along at least one straight line extending in a direction perpendicular to a pivot axis of the hinge 3. With the above-mentioned structure, the power pushing up the rear side of the seating surface 1 is maximized at an initial stage of a standing-up motion and minimized at a final stage of the standing-up motion. Thus, a user of this equipment is allowed to smoothly stand up and sit down.本發明旨在提供一種起立輔助裝置,其為小型、輕量,且可輕易設置於輪椅或家具,通用性高。 其中,在可以鉸鏈3開閉而接合之座面1與台座2之間,設置扭力線圈彈簧6b及雙列扭力彈簧6a與氣體彈簧4,將座面1之後部往上推,使座面1傾斜。在垂直於鉸鏈3之轉動軸之方向之至少1直線上,排列配置2個扭力線圈彈簧6b與雙列扭力彈簧6a。藉此,托高座面1之力於起立動作之初動期最大,於起立動作之結束期最小,可順暢且安全地進行起立及就座動作。1‧‧‧座面2‧‧‧台座3‧‧‧鉸鏈4‧‧‧氣體彈簧5a、5b‧‧‧接合部6a‧‧‧雙列扭力彈簧6b‧‧‧扭力線圈彈簧7a、7b‧‧‧接合構件
