Abstract

A wiping arrangement for windows of power vehicles has a wiping element with a wiper shaft, rotary direction-reversible drive having a rotatable driven element, swinging drive with a driving element rotatable about a center and provided with a gripping element and a guide, and connecting the driven element of said rotary drive with the wiper shaft of said wiping element so that when the driven element rotates in one direction the wiping element covers a circular, segment-shaped wiping field and performs wiping step over a predetermined wiping field, and when the driven element rotates in a reverse direction the gripping element arranged on the driving element of the swinging drive means moves radially away from the center with the aid of the guide and thereby the wiping element is transported to a parking position lying beyond the wiping field, a structural element connected and rotating together with the gripping element during the wiping step, but uncoupled from the gripping element for the radial movement of the latter, wherein the structural element is provided with a blocking element for blocking the structural element in position of the rotary direction reverse, and with a gu…
