Abstract

The invention relates to a wiper device ( 100 ) for cleaning vehicle windows, with a wiper arm ( 10 a - 10 d ) and a wiper blade ( 1 ) able to be fastened to the wiper arm ( 10 a - 10 d ), with a cleaning arrangement ( 40 a - 40 d ) having at least one first spray nozzle ( 42, 43 ) for spraying a washing fluid, wherein the cleaning arrangement ( 40 a - 40 d ) is connected directly with the wiper arm ( 10 a - 10 d ), and with a fastening arrangement ( 2 ) for connecting the wiper blade ( 1 ) with the wiper arm ( 10 a - 10 d ), wherein the wiper arm ( 10 a - 10 d ) has a mount ( 21 ), having an at least substantially U-shaped cross-section, with two parallel side walls ( 19, 20 ), and wherein the cleaning arrangement ( 40 a - 40 d ) is constructed as a separate component from the fastening arrangement ( 2 ) for the wiper blade ( 1 ). It is provided according to the invention that the cleaning arrangement ( 40 a - 40 d ) is located within the mount ( 21 ), and that the connection between the wiper arm ( 10 a - 10 d ) and the cleaning arrangement ( 40 a - 40 d ) is constructed as an engagement connection ( 98 ), as a form-fitting connection ( 105 ) or as a bayonet connection ( 88 ).

First claim

The invention claimed is:

1. A wiper device for cleaning vehicle windows, comprising:
a wiper arm elongated in a longitudinal direction;
a wiper blade able to be fastened to the wiper arm;
a cleaning arrangement having an elongated shape with two parallel first side walls and at least one first spray nozzle for spraying a washing fluid, wherein the cleaning arrangement is connected directly with the wiper arm, with a fastening arrangement for connecting the wiper blade with the wiper arm,
wherein the wiper arm has a mount, having an at least substantially U-shaped cross-section that is perpendicular to the longitudinal direction of the wiper arm, with two parallel second side walls, and wherein the cleaning arrangement is constructed as a separate component from the fastening arrangement for the wiper blade,
wherein the cleaning arrangement is located within the mount, the two parallel first side walls of the cleaning arrangement cooperating with free ends of the U-shaped cross-section on at least one part of the mount of the wiper arm, and the connection between the cleaning arrangement and the wiper arm is constructed as a bayonet connection, and
wherein connecting by the bayonet connection comprises:
fastening the wiper arm to the cleaning arrangement by movement of the wiper arm along a first mounting direction that is perpendicular to the longitudinal direction of the wiper arm; and
moving, subsequent to fastening along the first mounting direction, the wiper arm along a second mounting direction that is parallel to the longitudinal direction of the wiper arm.

2. The wiper device according to claim 1 , wherein the cleaning arrangement is constructed to hold the fastening arrangement for the wiper blade.

3. The wiper device according to claim 1 , wherein the at least one first spray nozzle is arranged in the region of a free end of the wiper arm on an end face of the cleaning arrangement.

4. The wiper device according to claim 3 , wherein at least one second spray nozzle is provided, which is arranged on a second side wall, different from the end face, or on an underside of the cleaning arrangement.

5. The wiper device according to claim 1 , wherein the engagement connection is constructed to connect the cleaning arrangement and the wiper arm with one another in a mounting direction running at least substantially perpendicularly to a longitudinal axis of the wiper arm.

6. The wiper device according to claim 1 , wherein a form-fitting connection is constructed to connect the cleaning arrangement and the wiper arm in a mounting direction running at least substantially parallel to a longitudinal axis of the wiper arm.

7. The wiper device according to claim 6 , wherein the form-fitting connection comprises guide elements constructed on the wiper arm, which cooperate with counter-elements for the guide elements constructed on the cleaning arrangement.

8. The wiper device according to claim 6 , wherein the insertion path of the cleaning arrangement is delimited by a rear side of the cleaning arrangement.

9. The wiper device according to claim 1 , wherein the cleaning arrangement has a mount region for the fastening arrangement of the wiper blade, such that in a mounted state of the cleaning arrangement the mount of the wiper arm encompasses the cleaning arrangement and a mount region of the cleaning arrangement encompasses the fastening arrangement.

10. The wiper device according to claim 1 , wherein the cleaning arrangement has a through-opening, which in a mounted state of the wiper blade is penetrated by an engagement element of the fastening arrangement, wherein the engagement element cooperates with an opening on the wiper arm.

11. The wiper device according to claim 1 , wherein the cleaning arrangement does not laterally project over the cross-section of the wiper arm in a region of the mount.

12. A wiper device for cleaning vehicle windows, comprising:
a wiper arm;
a wiper blade able to be fastened to the wiper arm;
a cleaning arrangement having at least one first spray nozzle for spraying a washing fluid, wherein the cleaning arrangement is connected directly with the wiper arm, with a fastening arrangement for connecting the wiper blade with the wiper arm,
wherein the wiper arm has a mount, having an at least substantially U-shaped cross-section, with two parallel side walls, and wherein the cleaning arrangement is constructed as a separate component from the fastening arrangement for the wiper blade,
wherein the cleaning arrangement is located within the mount, and the connection between the cleaning arrangement and the wiper arm is constructed as a formfitting connection,
wherein the formfitting connection comprises:
elongated projections projecting inward, in the U-shaped cross-section, from the two parallel sidewalls of the wiper arm, and
corresponding groove-like elongated cutout in the cleaning arrangement for cooperating with the elongated projections, and

wherein connection by the formfitting connection is along an insertion path that is delimited by a rear side of a closure cap of the cleaning arrangement.
