Abstract

This invention refers to a wiper system for windshields of motor vehicles. This wiper system comprises a wiper arm which can be attached to an oscillatorily drivable wiper shaft by way of an attachment piece. The wiper arm comprises a joint piece being essentially U-shaped in cross-section, flexibly embracing the attachment piece with its planar walls, and a cover for the attachment piece essentially U-shaped in cross-section and embracing the attachment plane with its planar walls. Furthermore, the wiping system is provided with a fluid line, which is guided along the wiper arm in order to supply a washing nozzle with washing fluid. The fluid line is easily assembled in the wiper arm at the attachment piece through a depression in which the fluid line extends. Beyond the depression in the attachment piece the fluid line extends through the wiper arm by being surrounded by a planar wall of the joint piece or the cover and a pressure spring.
