Abstract
A planetary gear arrangement for a seat adjustment mechanism, includes at least one inner, externally toothed fitting part and an outer, internally toothed fitting part, which fitting parts are pivotable in relation to each other about a pivot axis. An external toothing of the inner, externally toothed fitting part rolls along an internal toothing of the outer, internally toothed fitting part. A plurality of electric magnetizing coils are arranged annularly on the outer, internally toothed fitting part, the magnetizing coils being activatable alternately in an encircling manner in the circumferential direction of the outer, internally toothed fitting part such that the magnetic field of each magnetizing coil acts on the inner, externally toothed fitting part and sets the latter into a rotatory movement relative to the outer, internally toothed fitting part.
