ABSTRACT:
A side view mirror assembly having a housing and a spring biased mirror installed within the housing, the mirror having its reflecting surface facing outwardly of the housing, and a mirror orientation adjusting assembly including a pair of nested hemispheres detachably engaged for limited movement one relative to the other, one of said hemispheres having the mirror secured thereto, a clamp including a high strength spring arranged to immobilize said hemispheres in an effectively locked condition, and an electromagnet disposed when energized to reduce the effective force of the spring on the clamp so as to permit limited movement of the mirror carrying hemisphere for adjusting the orientation thereof. A suitable switch is coupled between the electromagnet and the vehicle battery, the ignition switch of the vehicle being interposed between said first mentioned switch and the vehicle battery. The adjustment can be manually effected or motorized with suitable electric motors being appropriately coupled to the hemisphere.
