Abstract

The seat member and the back member are adjustably mounted at each side of the chair in two support bearings or pivot joints of a chair base and are connected to one another by a third pivot joint. The seat member comprises an extension in the direction of the back member while the back member is maintained in spaced relationship to the third pivot joint by part of a lower strut portion on each side of the chair. A spring element is mounted at its ends on the free end of the extension part of the seat member and on the back member. In transition from the working position (full lines) into the relaxed or reclined position (broken lines), a relative motion is superimposed upon the pivoting motions of the seat member and of the back member. This relative motion produces unequal vertical downward displacements of the free end of the seat extension and of the backrest portion where it joins the strut portion. The action of this relative motion avoids the otherwise inevitable stretch effect on the occupant of the chair without requiring the supplementary linkages employed in known constructions.
