Abstract: A motor vehicle door, particularly for use as a rear door for a station wagon type or a sports utility type vehicle is openable from either the left side or the fight side. Mirror image mechanisms are provided at each side of the door to provide locking, unlocking and hinging at each side. A safety cam is included in each mechanism and the mechanisms communicate with each other so that the unlocking of one side prevents the unlocking of the other side. When both sides are locked, either one or the other side may be opened, in which case the unopened side acts as a hinge. The safety cam interlock arrangement prevents the opening of both sides at the same time.
