Abstract

The invention relates to a wiper device (10) for cleaning vehicle windows, with a wiper arm (11) and with a wiper blade (12) able to be fastened on the wiper arm (11), with a cleaning device (25), having at least one spray nozzle (44, 45), for spraying a washing fluid, wherein the at least one spray nozzle (44, 45) is arranged in the region of the free end of the wiper arm (11) and is connected directly therewith, and with a fastening device (35) for connecting the wiper blade (12) with the wiper arm (11), wherein the wiper arm (11) has a mount (28), having an at least substantially U-shaped cross section, with two parallel side wails (17, 18) for the fastening device (35) of the wiper blade (12), and wherein the cleaning device (25) is constructed on a component (27) which is separate from the fastening device (35) for the wiper blade (12). It is provided according to the invention that the at least one spray nozzle (44, 45) does not, at least laterally, project over the cross-section of the U-shaped mount (28).

Claims

1. A wiper device for cleaning vehicle windows, comprising:

a wiper arm;

a wiper blade able to be fastened on the wiper arm;

a cleaning device, having at least one spray nozzle, for spraying a washing fluid, wherein the at least one spray nozzle is arranged in the region of the free end of the wiper arm and is connected directly therewith; and

a fastening device 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 for the fastening device of the wiper blade, and wherein the cleaning device is constructed on a component which is separate from the fastening device for the wiper blade,

wherein the at least one spray nozzles does not, at least laterally, project over the cross-section of the U-shaped mount.

2. The wiper device according to claim 1, wherein the separate component terminates at least approximately flush with the fastening device on the side facing away from the wiper arm.

3. The wiper device according to claim 2, wherein the separate component and the fastening device form a shared end face on the side facing away from the wiper arm.

4. The wiper device according to claim 2, wherein the separate component has end face on the side facing away from the wiper arm, in which end face the at least one spray nozzle is arranged.

5. The wiper device according to claim 1, wherein the at least one spray nozzle is arranged on the side facing away from the wiper arm outside the mount for the fastening device.

6. The wiper device according to claim 1, wherein the separate component and the fastening device are arranged at least partially within the mount.

7. The wiper device according to claim 1, wherein the separate component is connected preferably detachably with the mount.

8. The wiper device according to claim 7, wherein in the assembled state of the wiper device the separate component is connected detachably with the fastening device, wherein the connection is constructed so as to be detachable independently of the connection between the separate component and the mount.

9. The wiper device according to claim 7, wherein the separate component has a mount, which is substantially U-shaped in cross-section, for the fastening device, into which the fastening device is able to be introduced in the direction of the wiper arm, so that in the assembled state of the wiper device, the mount of the separate component is arranged between the mount of the wiper arm and the fastening device.

10. The wiper device according to claim 9, wherein the mount of the separate component has a base and two guide faces arranged thereon, parallel to one another, which lie at least partially against side faces of the fastening device which are parallel to one another in the installed state of the wiper blade (12) on the wiper arm.

11. The wiper device according to claim 9, wherein the separate component has guide means for the form-fitting receiving of the fastening device in a plane running perpendicular to a mounting- or respectively dismantling direction and that the fastening device is able to be arrested via a detent connection in the mounting- or respectively dismantling direction on the wiper arm.

12. The wiper device according to claim 11, wherein the detent connection in the assembled state of the wiper device is guided through an aperture in the base of the mount and is arranged in operative connection with an opening in the mount of the wiper arm.

13. The wiper device according to claim 1, wherein at least two spray nozzles are provided with different spray angles, which apply the washing fluid onto different regions and/or on different sides of the wiper blade onto the vehicle window.

14. The wiper device according to claim 13, wherein the at least two spray nozzles are arranged one over the other in relation to a wiper blade longitudinal axis.

15. The wiper device according to claim 1, in the region of the mount, the wiper arm forms a first section, which continues over an obliquely-running second section into a third section running parallel to the first section, and that the second section in the transition region from the first section runs laterally flush with the first section.

16. The wiper device according to claim 4, wherein the fastening device has on the side facing away from the wiper arm an end face, which continues in a surface-flush manner into the end face of the at least one spray nozzle.
