ABSTRACT:
A mirror actuating device for automatically changing the orientation of side-view mirrors which are movably mounted to a vehicle, such as a semi-truck tractor, in response to the relative positions of the tractor and a trailer being towed by the tractor to provide a variable field of view to a driver of the tractor through the mirrors. The actuating device has two actuating plates slidably mounted to the tractor, cables interconnecting the actuating plates to the mirrors, an actuating pin attached to the trailer, and an arm pivotally mounted between its ends to the tractor and having one end connected to the actuating plates and another end connected to the actuating pin. The necessary operating connection between the actuating plates on the tractor and the pin carried by the trailer is automatically made when the tractor and trailer are hooked together in the normal manner. As the tractor-trailer combination negotiates a turn the trailer assumes various angles with respect to the tractor and in doing so the mirrors mounted on the tractor are suitably moved by the actuating device to produce a field of view which is substantially clear of the trailer.
