Virtual swivel device with movement limitation

A limiting device limiting a pivot angle of a pivoting device, the pivoting device pivoting a seat of a chair about a virtual pivot point relative to a base of the chair;

• the limiting device including:
• a first and a second central parts;
• wherein:
• the first central part is directly or indirectly coupled to the base of the chair around a first inner axis;
• the second central part is directly or indirectly coupled to the seat of the chair or a carrier for the seat of the chair around a second inner axis;
• and
• the first and the second central parts are pivotally coupled to one another around a central inner axis that is substantially parallel to the first and second inner axes;
• wherein the limiting device is rotatably mounted on the base of the chair via a first edge part so as to rotate about a first outer axis that is substantially perpendicular to the first inner axis;
• the limiting device is additionally rotatably mounted on the seat of the chair or on the carrier for the seat of the chair via a second edge part so as to rotate about a second outer axis that is substantially perpendicular to the second inner axis;
• and
• the limiting device further comprises a stop disposed on the first or the second central part, the stop being configured to limit the pivotal coupling between the first and the second central parts such that if the first and second outer axes share a common plane the limiting device prevents the first inner axis, the second inner axis, and the central inner axis from sharing a common plane.
