Abstract

A wobble joint fitting for a vehicle seat has a first joint arm, which carries an internal gear and forms a first bearing surface, which are central to a main axis, and a second joint arm to which an eccentric gear is allocated, which comprises an externally toothed pinion and a second bearing surface. The pinion and the second bearing surface are central to an eccentric axis. An eccentric driving part is disposed in the area between the first bearing surface and the second bearing surface. Clamping parts, in a clamping state, displace the eccentric axis relative to the main axis. The eccentric driving part defines the eccentric. The rotary drive of the eccentric driving part causes a rotation of the pinion relative to the internal gear even without the clamping parts being present, wherein only play compensation is not obtained without the presence of the clamping parts.
