JP3061847U - Chair to reduce back muscle fatigue - Google Patents

Abstract

(57) [Summary] [Problem] Since desk work such as a personal computer and a word processor tends to be inclined forward, the backrest may not be useful. The same situation applies to those who have suffered back injuries for some reason, those who cannot exert power on their backs due to osteomyelitis, etc., and those who have difficulty applying power. A chair that reduces back muscle fatigue even in such a case is provided. SOLUTION: A chair having a structure capable of supporting the weight of an upper body by providing a chest pad which is in contact with a chest while sitting on a chair. However, in a chair with a fixed breastplate from the beginning, the user needs to move over to sit on the chair,
It's an exaggeration to restrict how you can sit in a chair. Therefore, a chair that can be used as an elbow pad in a normally folded state is a chair that can be expanded and used as a chest pad.
