Abstract

A chair is provided which has a tiltable seat carrier and a tiltable backrest on the backrest carrier which are forcibly coupled to one another, and which has an individual adjustment feature for the tilt of the seat carrier in relation to the backrest carrier. Provided on the underside of the seat carrier is a bearing block having a slideway contour and a vertical slot in which the flange of a lifting element is mounted vertically movably, wherein the lifting element has a substantially triangular collar which slides on the substantially rectangular slideway contour when the flange moves vertically. The tilt of the seat carrier can be adjusted to be steeper or flatter by turning the lifting element, and the limit positions are completely stable such that the possibility of automatic unlocking is eliminated.
