Abstract
Abstract AN OUTSIDE REAR-VIEW MIRROR FOR A TRACTOR-TRAILER VEHICLE COMBINATION WHEREIN THE ANGULATION OF THE MIRROR CHANGES PROGRESSIVELY DURING THE COURSE OF A TURN TO PROVIDE THE VEHICLE OPERATOR WITH CONTINUOUS REAR VISION AT AND BEYOND THE REAR OF THE TRAILER. MIRROR ANGULATION CHANGES ARE PROVIDED BY AN OPERABLE INTERCONNECTION BETWEEN THE MIRROR AND THE VEHICLE''S STEERING ASSEMBLY. A MANUAL OVERRIDE IS OPERABLY CONNECTED TO THE INTERCONNECTION AND IS CONTROLLED BY THE OPERATOR IN THE VEHICLE CAB TO ENABLE LANE SCOUTING AND THEREBY FACILITATE LANE CHANGES DURING STRAIGHT-AHEAD ROAD TRAVEL.
