Abstract:
1. A wobble joint fitting for a vehicle seat comprising: a main axis; a first joint arm, the first joint arm being configured and arranged to carry an internal gear and form a first bearing surface defining an outer surface, the internal gear and the first bearing surface being arranged central to the main axis; an eccentric gear defining an eccentric axis; a second joint arm, the eccentric gear being allocated to the second joint arm, the second joint arm comprising a) an externally toothed pinion located within the internal gear and in engagement with the internal gear, and b) a second bearing surface defining an inner surface, wherein the pinion and the second bearing surface are central to the eccentric axis; an annular eccentric driving part disposed in the area between the first bearing surface and the second bearing surface, wherein the eccentric driving part defines an eccentric and comprises an eccentric area contacting the first bearing surface and the second bearing surface with a fabrication-related play; a control part having a control lug with a flank, wherein the eccentric driving part is arranged in driving connection with the control part; clamping parts that each have a narrow end and a wide end and contact the first bearing surface and the eccentric driving part, the clamping parts displacing, in a clamping state, the eccentric axis relative to the main axis whereby the wobble joint fitting is made free from backlash; wherein, when the control part is rotated, the flank contacts against the narrow end of one of the clamping parts and moves said clamping part until said clamping part contacts against the eccentric area so that, during further drive movement, the eccentric area is also moved thereby and a rotary drive of the eccentric driving part, the rotary drive rotating the pinion relative to the internal gear, the rotary drive even being in a driving connection with the pinion in case the clamping parts are not present in the wobble joint fitting, wherein there is no compensation of backlash when the clamping parts are not present in the wobble joint fitting.
