ABSTRACT:
A wiping device for windows of power vehicles, comprises a swingably movable wiping lever, a swinging shaft having a swinging axis, a guiding piece connected with the swinging shaft, an elongated lifting element which is radially displaceable relative to the swinging axis, the lifting element having an end which faces away from the swinging axis, a wiper arm articulately connected with the side of the lifting element, a wiping blade arranged on the wiper arm, a spring element arranged to press the wiping blade against a pane to be wiped, so that the wiping blade is subjected via the wiper blade to a swinging movement and via the lifting element to a displacement movement which is superposed upon the swinging movement and extends transversely to the swinging movement, the lifting element being provided with a movable abutment shoulder which extends transverse to its direction of elongation, the guiding piece having a rear counter shoulder as considered in directional movement of the lifting element and cooperating with the abutment shoulder, the abutment shoulder abutting against the counter shoulder and being in working connection with the wiping blade so that its relative movement relative to the wiping blade acts upon the wiping blade against a pressing action of the spring element.
