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.

Dependent claims

A wiper system for windshields of motor vehicles having a wiper arm adapted to carry a wiper blade and which can be attached to an oscillatorily drivable wiper shaft, said wiper system comprising:

an attachment piece having two outside planar walls running in a longitudinal direction, said attachment piece having a depression extending along a longitudinal axis in one of said planar walls;
an elongated Joint piece pivotally coupled to said attachment piece, said elongated joint piece generally having a U-shaped, transverse cross-section, including two planar walls, said planar walls embracing said attachment piece;
a cover, said cover generally having a U-shaped cross-section including two planar walls, said planar walls of said cover connected to said attachment piece;
and
a fluid line positioned in said depression of said attachment piece and extending along a longitudinal axis, said fluid line partially enclosed by at least one of said planar walls of said elongated joint piece and by said planar walls of said cover,
wherein said attachment piece planar walls are essentially symmetrically formed with regard to a first center plane, and said joint piece and said cover are formed symmetrically with regard to a second center plane, and said first center plane extends parallel to said second center plane.
