CHAIR-USE AUXILIARY CHAIR FOR IMPROVING POSTURE

摘要

The present invention consists in a posture-improving auxiliary chair for use with a chair designed to improve the posture. An object of the invention is to improve the posture by routinely using the auxiliary chair which is placed on a chair. According to this invention, the front center of the concavely curved seat face portion is recessed in the form of a band extending toward the rear center, and raised portions gently raised from the lateral sides toward the recessed portion are formed on the front section of the seat face portion. In the vicinity of the foots of the raised portions there are formed fan-shaped inclined surfaces gently slanting in an oblique direction toward the front. In the center of the bottom of the seat formation part there is formed a convexly curved portion, on forward and rearward extensions of which there are formed a front stop portion and a rear stop portion, respectively. It is a seat formation support part that includes these component elements and supports the seat formation part from below. These parts are joined together in one-piece and all of the corners are chamfered, whereby a generally rounded auxiliary chair for use with a chair for improving the posture is obtained.
