Abstract
A chair has both a tiltable seat and a tiltable backrest mounted on a backrest support. The chair includes a pedestal mounted on a bottom of the tiltable seat. An eccentric disk is seated in the pedestal so as to be movable therein. A rod eccentrically penetrates the eccentric disk via a prismatically-shaped cross-section recess through the eccentric disk so that the rod is not movable with respect to the eccentric disk. A handle is connected on an outer end of the rod for use in turning the rod together with the eccentric disk. An arm is mounted on the backrest support of the tiltable backrest, wherein the rod is seated in the arm in a movable manner.
