Abstract

The present invention is directed to provide the back support for an ergonomic chair, which can adaptively adjust the position of a lumbar rest to the body size of a user, minimize the movement of a user's back in the horizontal direction when the one back type backrest is pushed back and rotate the backrest in the horizontal direction along with the horizontal movement of the user's back when the one back type backrest is in its upright position. To this end, the back support device for a chair of the present invention comprises: a one back type backrest for supporting both sides of a user's back all together; a backrest support for supporting the backrest; a fixing unit disposed between an upper part of the backrest and the backrest support, for fixing the upper part of the backrest to the backrest support; an elastic unit disposed between a lower part of the backrest and the backrest support, for providing the lower part of the backrest with an elastic force to be movable in the horizontal direction relative to the backrest support when an external force is applied to the backrest; a lumbar rest provided to the backrest support, for supporting the lumbar of the user by pressurizing the backrest; and a back-and-forth moving unit for moving the lumbar rest back and forth.
