Patent ID: 8616646

Claim:
An adjuster for a vehicle seat, the adjuster comprising: a drive; a gear stage driven by the drive, the gear stage comprising a drive wheel comprising drive teeth, the drive wheel being rotatable about a first rotational axis and the gear stage comprising a driven wheel comprising driven teeth, the driven wheel being rotatable about a second rotational axis and meshing with the drive wheel with a fluctuating gear ratio; and at least one load bearing gear driven by the gear stage, the at least one load bearing gear being a geared fitting with fitting parts performing a relative rotation with a superimposed wobble motion, wherein at least two of the drive teeth or at least two of the driven teeth in the circumferential direction of the associated rotational axis have different dimensions or different spacings from the adjacent teeth, or in the axial direction of the associated rotational axis has different dimensions or different axial positions, said drive wheel or the driven wheel being of frustoconical-like configuration, said drive teeth or driven teeth being arranged along a ring in one plane, a normal axis thereof being oblique to the associated rotational axis, wherein the ring of the drive teeth or of the driven teeth is supplemented by filling material in an axial direction, which remains without contact with the drive teeth during an adjusting process of the drive wheel and the driven wheel.
