Abstract The foot bearing the seat surface of a seat is divided at a distance of 20-30cm from the seat surface. Between the mutually facing end faces of the two foot parts (5a,5b) a rubber cushion (9) is arranged, the circumferential area of which is widened to form a brake ring (11). The elastic restoring force, working counter to the inclination of the seat, of this cushion is reinforced by two further cushions (16,17) arranged within the foot parts (5a,5b). By means of the suitable arrangement of sliding elements with low friction (T1- T3), the mutual rotation between the two foot parts (5a,5b) is ensured. Thanks to this construction, the seat surface can be swiveled in a tumbling manner in such a way that every point of said seat surface moves on an imaginary spherical surface and thanks to the mentioned elastic restoring force, the seat part always returns automati- cally to its initial position. When the seat is inclined, the then undesired rotation of the upper seat part (5a) is prohibited by the friction between its edge area (R) and the compressed brake ring (11). (Fig. 3)
