Abstract

In an adjusting gear in a motor vehicle, especially for a motor-driven seat adjustment mechanism, with an essentially pot-shaped transmission housing in which are supported on a bearing shaft, starting from the pot bottom, a pinion, a planet gear carrier with planet gears, a sun gear meshing with the planet gears as well as a worm gear non-rotatably connected with the sun gear; according to this invention, the end face of the planet gears opposite the pot bottom are provided with at least one orientation surface, the worm gear is also provided on its end face opposite the pot bottom with at least one orientation surface and the end face of the planet gears are each constructed with an abutment surface for the abutment at the worm gear. This enables a facilitated assembly of the adjusting gear, especially with the aid of an assembly robot.
