At present, the electric chair of old man in our country has a certain gap in the product process, quality and innovation when compared to the foreign products. Aiming at the shortcomings of the existing products on the market, this paper puts forward a kind of product which can not only realize the function of footrest lifting, backrest leaning, auxiliary standing, anti-dumping, but also can meet the requirements of no distance against the wall, according to the research status at home and abroad. This article first determines the function parameter requirements from the perspective of ergonomics and disintegrates the function into several modules. Aiming at every function module, put forward a variety of mechanism schemes and carry on the analysis and comparisons successively, ultimately, confirm the overall plan of the old man chair and establish the struct
