ABSTRACT:
According to a method for inclining a chair seat, and a chair having an inclinable seat, blood circulation is improved by making the structure of the chair simple and of such a structure as to cause elongating of the backbone of a person being seated, and dissipating of the pressure at the rear side of the femoral region in the vicinity of the knees. In this chair, a backrest attaching member is pivotally supported at the rear side of an attaching frame for rearward inclination, and at the same time is spring-pressed toward the attaching frame. A push-up member is vertically attached to a horizontal portion of the backrest attaching member. A seat receiving plate is pivotally supported at the front side of the attaching frame for upward inclination, and the seat receiving plate is engaged with an upper end of the push-up member. A backrest is attached to the backrest attaching member, and a seat is attached to the seat receiving plate. With this arrangement, the backrest side of the seat is upwardly inclined by causing the backrest to be inclined rearwardly.
