Abstract

A windshield wiper unit with a wiper arm of telescopic construction which has a housing driven to and fro round an axis of rotation by a driving motor and a slide movable in relation to the housing, this slide being displaceable by a crank assembly is so designed that the various bearings are subjected to little load and so that compact construction is possible. This is achieved by having the connecting rod belonging to the crank assembly above or below the slide and linked to the slide between the two bearings for it and by having the distance between the two bearings at least as great as the stroke of the slide.
