PROBLEM TO BE SOLVED: To provide a rising aid implement capable of preventing the large change of an actual seat surface as much as possible even at a sitting position of a chair or the like.SOLUTION: The rising aid implement uses an expansion bag 11 which forms a hollow cylindrical shape and keeps a flat and thin state when air is not supplied to an inner cavity 11a. Consequently, even when the rising aid implement 10 whose expansion bag 11 is not expanded is placed at the sitting position of the chair or the like, the change of the actual seat surface is little. Thus, the large change of the actual seat surface is prevented as much as possible even when the rising aid implement 10 is placed at the sitting position of the chair or the like, and there is no risk of giving mental and physical fatigue to a user due to the feeling of incompatibility in a sitting posture caused by the change of the actual seat surface.COPYRIGHT: (C)2009,JPO&INPIT【課題】椅子等の着座位置に置いても実際の座面が大きく変化することを極力防止できる立ち上がり補助具を提供する。【解決手段】中空円筒状を成し内部空洞11aに空気が供給されていないときに平坦で薄い状態を保持する伸縮袋11を用いているので、伸縮袋11が膨らんでいない立ち上がり補助具10を椅子等の着座位置に置いても実際の座面の変化は僅かである。従って、立ち上がり補助具10を椅子等の着座位置に置いても実際の座面が大きく変化することを極力防止できると共に実際の座面の変化に依る着座姿勢の違和感が原因となって心身的な疲労を利用者に与える恐れがない。【選択図】図1
