Abstract

A chair, particularly an office chair, has a vertically adjustable seat carrying means at which, by means of a control linkage, a seat plate that can be adjusted in its slope is coupled as well as a backrest are coupled. The backrest adjusts itself as a function of the slope of the seat plate. The control linkage comprises coupling elements that are held at the seat carrying means and are arranged in the shape of scissors and are coupled to seat parts of a seat surface that are flexibly connected with one another. By means of this coupling, an imaginary axis of rotation in the knee area is formed that is transversely extending and unchangeable and is located in front of the seat surface. This axis of rotation in the knee area is located in an intersecting line that is formed between a horizontal plane of the seat surface when in a basic adjusted position and a diagonal plane of one coupling element when in an inclined adjusted position. As a result, an uncomfortable sitting is avoided when the chair is adjusted because no change of the user's relevant support points takes place with respect to the chair as well as of the leg supporting points with respect to the contact surface of the chair.
