  • Patent number: 4437143
    Abstract: A retractable headlamp assembly for automobiles in which a headlamp, pivotally mounted on the automobile frame, is operatively coupled to the rotatable shaft of a motor by a link mechanism. The motor, operating through the link mechanism, is energizable to cause the headlamp to be moved angularly between a first position at which the headlamp projects out of the front hood of the automobile, and a second position at which the headlamp is retracted within the front hood. An adjustable stop is provided to stop the headlamp at the first position, which adjustable stop is adjusted to bring the first position into conformity with an angularly displaced position of the rotatable motor shaft, which is displaced through a slip angle from a normal stopping position. Such an arrangement assures that the headlamp can be stopped at a fixed position at all times for emitting a correctly directed beam of light irrespective of the varying positions at which the motor can stop.
