Abstract
A chair has a rocking mechanism with a fixed base support having a conical receptacle to be placed on a chair pillar. The base support is pivotally connected to a mechanism upper part which forms a housing at least partially enclosing the base support. A pivot axis of the mechanism upper part runs transversely to the chair longitudinal direction and is arranged next to the conical receptacle, as seen in the chair longitudinal direction. A spring element acts between the mechanism upper part and the base support for returning the mechanism upper part from a pivoted position into a starting position. The rocking mechanism is fastened via the mechanism upper part to a seat, a seat support, or a frame of the chair, or else, the rocking mechanism is integrated so that part of the seat, seat support or chair frame forms the mechanism upper part.
