Abstract

A windshield wiper arrangement for motor vehicles which includes a telescopically constructed wiper arm having an effective length which can be altered during a wiping motion by a crank drive which acts upon the wiper arm and serves to create a particularly good wiping field. In order to enable a particularly compact and reliable construction, the drive for the windshield wiper arrangement is accommodated in a lower part of the wiper arm which is constructed as a housing. The drive includes a toothed gearing driven by a wiper drive unit, with the toothed gearing serving to drive the crank drive. The housing is constructed in such a manner that the windshield wiper arm and crank drive have a common axis of rotation.
