Abstract
A wiper for a rear view mirror includes a vertical wiper blade which traverses the mirror from side-to-side on a horizontal linear path. The wiper blade is carried on a spring-urged extension of a drive arm which is shaped to reach around one vertical edge of the mirror. The drive arm is powered by a highly simplified lightweight drive mechanism at the rear of the mirror held on a support bracket which embraces the sides of the mirror and is suspended from the top of the mirror through a sturdy top mounting bolt connected with the main mirror support bracket.
