Abstract

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).
