ABSTRACT:
A chair having adjustable synchronous tilting, where a seat (7) pivotable about a seat pivot axis (5) and a back-rest support (11) pivotable about a back-rest pivot axis (9) are coupled by a coupling link (15) for simultaneous inclination changes, the synchronous tilting ratio, i.e. the ratio of the coupled inclination changes of seat and back-rest can be changed and individually adjusted, for example by displacing the engagement points of the coupling link (15) at the seat (7) and the back-rest support (11), respectively.
