PROBLEM TO BE SOLVED: To improve robustness and reliability of a wheelchair that has a function to assist a users standing-up by pulling up a rear end part of a seat surface with a belt attached to a backrest part.SOLUTION: One end part of a belt 4 joined to a rear end part of a sear surface 1 is wound around half a periphery of a rod-like member 2 attached to an upper part of a backrest part almost horizontally, then is joined to a lever 5 that has a fulcrum of a lower part of the seat surface, and the belt 1 is pulled up by operation of a joint part of the lever 5 and the belt 1. The horizontal rod-like member 2 is joined to a vertical rod-like member 3 supporting the backrest part by using a joint member separately adjusted. It is prevented that the joint member moves by body weight given onto the seat surface 1 with a stopper 14 separately adjusted.COPYRIGHT: (C)2014,JPO&INPIT【課題】座面の後端部を、背もたれ部に取り付けたベルトで引き揚げることにより、利用者の起立を補助する機能を有する車椅子の、堅牢性や信頼性を向上する。【解決手段】座面1の後端部に接合したベルト4の他方の端部を、背もたれ部の上部に略水平に取り付けた棒状部材2の周囲を半周だけ周回した後、座面の下部の支点を有する梃子5に接合し、梃子5とベルト1の接合部の作動により、ベルト1の引き上げを行う構造とし、水平の棒状部材2を、背もたれ部を支持する縦方向の棒状部材3に、別途に調製した接合用部材を用いて接合し、当該接合用部材が座面1に負荷される体重で下方向にずれるのを、やはり別途に調製したストッパー14で防止する構造とする。【選択図】図1
