In a gear train (10, 30) for an actuator, in particular of a vehicle seat (2), the gear train comprises a drive (11) that can be rotated about a rotational axis (A), at least one eccentric cam (12, 13) that is driven by the drive (11), a pinion (14, 15) that is driven by the eccentric cam (12, 13), a gear ring (16), which meshes with the pinion (14, 15) and in relation to which the pinion (14, 15) executes a rolling motion that defines a point of rolling contact (W), and a take-off drive (18) that taps the relative rolling motion. At least some sections of the material of the pinion (14, 15) and/or the ring gear (16) 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).
