Adjuster for a vehicle seat

A motor vehicle seat comprising:

• vehicle seat components;
• and
• an adjuster connected to one or more of the vehicle seat components, the adjuster comprising:
• an adjuster drive;
• a gear stage connected to the adjuster drive and driven by the adjuster 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, two of the drive teeth or two of the driven teeth in the circumferential direction of the associated rotational axis having different dimensions or different spacings from the adjacent teeth, or in the axial direction of the associated rotational axis having different dimensions or different axial positions, said drive wheel or the driven wheel being of frustoconical-like configuration, wherein said drive teeth or driven teeth are 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;
• and
• a load bearing gear connected to the gear stage and driven by the gear stage, the load bearing gear being a geared fitting with fitting parts performing a relative rotation with a superimposed wobble motion.

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 and a driven wheel comprising driven teeth, said drive wheel being rotatable about a first rotational axis, said driven wheel being rotatable about a second rotational axis, wherein said drive wheel is of frustoconical-like configuration;
• a filling material;
• 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 driven teeth have different dimensions and different spacings from adjacent driven teeth in a circumferential direction of said second rotational axis, each of said drive teeth having different dimensions in an axial direction of said first rotational axis, each of said drive teeth having an outermost surface, said outermost surface being spaced from said first rotational axis by a radial distance, wherein said radial distance increases with respect to an axial direction of said drive wheel, wherein said outermost surface engages one or more of said driven teeth to provide a fluctuating gear ratio, said filling material engaging said outermost surface.
