1. An adjustment device for adjusting an orientation of a vision element of a vehicle about a first pivot axis and a second pivot axis, the adjustment device comprising:
a base for coupling to the vehicle;
a frame pivotably coupled to the base, the frame having a first frame part being pivotable relative to the base about the first pivot axis and a second frame part being pivotable relative to the first frame part about the second pivot axis; and
a drive unit for driving the frame pivotally about the first pivot axis and the second pivot axis;
wherein the drive unit comprises a first powertrain operationally between the first frame part and the base, having a first electromotor connected via a first transmission to a first driven element for driving the first frame part relative to the base about the first pivot axis, and a second powertrain operationally between the first frame part and the second frame part, having a second electromotor connected via a second transmission to a second driven element for driving the second frame part relative to the first frame part about the second pivot axis;
wherein a power rating of the second electromotor is lower than a power rating of the first electromotor; and
wherein the second transmission applies a second speed-reducing transmission ratio from the second electromotor to the second driven element, the second speed-reducing transmission ratio providing a greater speed reduction than a first transmission ratio from the first electromotor to the first driven element.
