Abstract

A chair, in particular an office chair, including a seat and a back rest which are pivotal in relationship to a supporting column supporting these. The back rest is mounted on a carrier for pivotal movement about a fixed first horizontal axis. A downwardly directed first control means is mounted on the carrier for pivotal movement about a second axis which is located in front of the first axis. The lower area of the first control means is mounted for pivotal movement about a third axis at the lower end of a second control means. The second control means extends upwardly to the front area of the seat and there is connected for pivotal movement about a fourth axis. The carrier is connected at a fifth horizontal axis located below the second axis on the carrier to a substantially horizontal third control means, the other end of which third control means is pivotally coupled connected for pivotal movement about a sixth axis, lying above the third axis, with the second control means. The carrier, through which the back rest is pivotally mounted to the column, and the second control means, which supports the front area of the seat, are therefore coupled through the intersecting control m…
