A gear step ( 1 ) for an actuator in a motor vehicle, in particular for a vehicle seat, comprises a housing ( 3 ) provided with a drive ( 1 ) mounted thereon in such a way that it is rotatable around an axis (A), and a driven output ( 21 ) rotatable about a second axis (B) differing from the axes (A). The drive ( 11 ) is used for receiving the driven output ( 21 ) by way of at least one rolling body ( 31 ), so that the axes (A, B) are parallelly offset by an eccentricity (E) and the driven output is driven by rotating the thus obtained rolling eccentricity, wherein the driven output ( 21 ) carries out a tumbling rolling movement on the housing ( 3 ) by way of a friction oscillating gear ( 33, 35 ).
