In a windshield wiper, which includes a wiper arm carrying a wiper blade and driven by a wiper shaft to oscillate against a windshield pane being wiped, a lever mechanism is provided, which imparts to the wiper arm additionally a straight-line shifting movement in the direction of elongation of the wiper arm. The lever mechanism includes two four-joint guides, each of which includes two rocking levers positioned at two sides relative to the axis of the wiper arm, and a coupling rod which is connected by joints to each of the rocking levers and to the wiper arm.

Windshield wiper device

A wiping arrangement for wiping a vehicle window has a rotatable output shaft, a wiper shaft connected with a wiping element, and pendulum elements for converting the rotary movement of the output shaft into the pendulum movement of the wiper shaft. The pendulum elements include a crank member connected with and rotatable by the output shaft, a rocker arm connected with the wiper shaft, and a connecting rod which is pivotally connected with the crank member and the rocker arm. Elements are provided which allow swinging of the connecting rod even when the wiper shaft is blocked, for example as a result of snow accumulation in the region behind the wiper shaft. Thus, the connecting rod can swing about a hinge which connects the same to the rocker arm, and thereby the crank member can rotate despite the blocking of the wiper shaft.

Wiping arrangement for wiping a vehicle window

A motion-transmitting arrangement, particularly for windshield wipers, has a drive with a rotary output shaft on which a crank member is mounted for rotation. A crank rod has one end connected to a crank pin which is transversely spaced from the shaft, and its other end is pivoted at one location to a member which latter is also pivoted at another location and which is coupled with an element (e.g., a wiper blade) to be moved. An arrangement is provided for varying the distance between the shaft and the crank pin and/or between the crank pin and the pivot at the one location and/or the pivot at the one location and the pivot at the other location.
