Drive device for adjusting the mirror assembly of a rearview mirror

The invention relates to a drive device for adjusting the mirror assembly of a rearview mirror comprising a mirror base and a mirror head, which accommodates the mirror assembly and which can be positioned between a first and a second position via a pivot. The drive device comprises an electric motor assembly and a control switch, which specifies the direction of the adjustment of the mirror assembly and which, according to the actuation thereof, furnishes electrical signals to the electric motor assembly for the adjustment of the mirror assembly. The inventive device is also equipped with a switch-over device, which comprises a position switch and which, according to the switching state of the position switch, switches over the signals furnished to the electric motor assembly in such a manner that in both the first as well as in the second position of the mirror head, the relation between the direction of adjustment, which is specified by the control switch, and the adjusting direction of the mirror assembly remains unchanged.
