19. A toilet comprising a toilet seat as claimed in claim 1 secured to a lavatory body.

20. The toilet as claimed in claim 19 , wherein the second assembly is upwardly foldable in relation to the lavatory body.

21. A toilet seat comprising a first assembly and a second assembly, which are pivotably connected by hinge joints, the second assembly having a lavatory seat ring which is rotatably spinable and driven by a drive device including a toothed belt and electric motor, and an automatic cleaning device which includes a cleaning arm pivotable about a vertical axis between an idle position in which a longitudinal axis of the cleaning arm is parallel to a common axis of rotation of the hinge joints and a cleaning position in which the longitudinal axis is perpendicular to the common axis of rotation of the hinge joints.

22. A toilet seat comprising:

a first assembly having a mounting panel that is securable to a rear section of

a lavatory body; and

a second assembly having

a lavatory seat ring including a seat portion for supporting a user in a seated position, and

a bearing frame for rotatably supporting the lavatory seat ring,

wherein the first assembly and the second assembly are pivotably connected by hinge joints having a common axis of rotation, and
