Actuator system, rear view device, motor vehicle and adjustment method

A method of operating an actuator system for a rear view device of a motor vehicle for adjustment of a component, when being connected to the actuator system, the method comprising:

• providing the actuator system in a released position, with the actuator system comprising a drive system adapted to rotate a bayonet gear around a rotational axis (R), the bayonet gear being coupled via at least one engagement element to a latching barrel, wherein the latching barrel is cylindrically shaped with a cylindrical surface as an engagement surface and oppositely arranged first and second sides each directed towards one of two worm gears being arranged along the rotational axis (R) as a first worm gear adjacent to the first side and as a second worm gear adjacent to the second side of the latching barrel, wherein shaped guiding members to guide the at least one engagement element extend on the engagement surface from the first side to the second side while at least partly circulating around the engagement surface, wherein the guiding member comprises at least a first and a second stop position;
• moving the latching barrel from the released position in axial direction along the rotational axis (R) by rotating the bayonet gear via the drive system in one rotational direction, wherein the at least one engagement element moves along the guiding members between first and second stop positions until the engagement element is engaged in the first or second stop position;
• rotating the latching barrel by rotating the bayonet gear by the drive system further in the same rotational direction, when the engagement element is engaged in the first or second stop position;
• engaging one of the worm gears by the latching barrel as a result of the latching barrel being firstly axially moved and secondly rotated;
• and
• rotating the engaged worm gear by rotating the bayonet gear via the drive system further in the same rotational direction.
