Abstract
In a gear train () for an actuator, in particular of a vehicle seat (), the gear train comprises a drive () that can be rotated about a rotational axis (A), at least one eccentric cam () that is driven by the drive (), a pinion () that is driven by the eccentric cam (), a gear ring (), which meshes with the pinion () and in relation to which the pinion () executes a rolling motion that defines a point of rolling contact (W), and a take-off drive () that taps the relative rolling motion. At least some sections of the material of the pinion () and/or the ring gear () in the vicinity of the point of rolling contact (W) are elastically deformable, in order to produce surface contact at the point of rolling contact (W).
