Abstract
A chair with a backrest is arranged so that the seat can be shifted forwardly to a rest position upon a rearward inclination of the backrest. The front end of the seat is supported pivotably on a support base, and the seat is movable forwardly and rearwardly. A balancing member is provided below the seat, and the support base supports a fulcrum of the balancing member set between a front and rear point of action of the balancing member. A backrest is provided on the rear end of the balancing member, and a rear part of the seat is supported on the rear point of action of the balancing member through seat receiving means. An upward movement of the front point of action of the balancing member is translated by motion translating means to a forward movement of the seat.
