Gear train for an actuator

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).
