Abstract
An adjustment drive includes a drive motor, and a drive train in driving relationship with the drive motor for reducing a motor speed of the drive motor. The drive train includes a plurality of gear wheels operated by the drive motor and intermeshing with one another to form a chain to define at least one gear stage, whereby at least the plurality of gear wheels is supported by a carrier that defines thereby a separate drive unit.

A self-contained module of an adjustment drive, comprising:
- a carrier;
- a drive motor mounted to a first side of the carrier and having a splined output;
- and
- a drive train in driving relationship with the drive motor, said drive train including
- a first gear wheel mounted to a second side of the carrier and meshing with the output of the drive motor,
- a first double spur gear assembly mounted to the second side of the carrier and having two spur gears with different number of teeth, wherein the first gear wheel is operatively connected to the spur gear of greater number of teeth in overlapping relationship,
- a second double spur gear assembly mounted to the first side of the carrier and having two spur gears with different number of teeth, wherein the spur gear of smaller number of teeth of the first double spur gear assembly is in mesh with the spur gear of greater number of teeth of the second double spur gear assembly for reducing a motor speed of the drive motor, and
- a hollow shaft operatively connected to the spur gear of smaller teeth of the second double spur gear assembly for attachment of a control element to be adjusted.
