Abstract

The invention relates to a window-wiping device for a vehicle having a fastening element fastened to a drive shaft, in particular a motor vehicle. The window-wiping device comprises a wiper blade having an elongate upper part, which is at least partially flexible, an elongate lower part, which is at least partially flexible, a plurality of connecting elements for connecting the upper part and the lower part, wherein the connecting elements are spaced apart from each other along a longitudinal extent of the wiper blade, and wherein the connecting elements are designed to enable a motion of the upper part and of the lower part in relation to each other with a motion component along a longitudinal extent of the wiper blade, and a wiper-blade-side fastening part, wherein the wiper-blade-side fastening part can be detachably connected by means of a linear motion on the fastening element, and the wiper-blade-side fastening part can be connected to the fastening element in such a way that a rotational position about an axis perpendicular to the longitudinal extent of the wiper blade and perpendicular to the linear motion is defined by a support and a further contact point.

First claim

What is claimed is:

1. A window wiper device ( 100 ) for a vehicle having a fastening element ( 50 ) fastened to a drive shaft, comprising a wiper blade ( 2 ) having
an elongate upper part ( 10 ) which is at least partially of flexible form,
an elongate lower part ( 12 ) which is at least partially of flexible form,
multiple connecting elements ( 18 ) connecting the upper part ( 10 ) and the lower part ( 12 ), wherein the connecting elements ( 18 ) are spaced apart from one another along a longitudinal extent ( 8 ) of the wiper blade ( 2 ), and wherein the connecting elements ( 18 ) are configured to permit a movement of the upper part ( 10 ) and of the lower part relative to one another with a movement component along the longitudinal extent ( 8 ) of the wiper blade ( 2 ), and
a wiper-blade-side fastening part ( 30 ), wherein the wiper-blade-side fastening part ( 30 ) is detachably connectable to the fastening element by way of a linear movement, and the wiper-blade-side fastening part ( 30 ) is connectable to the fastening element such that a rotational position about an axis perpendicular to the longitudinal extent of the wiper blade and perpendicular to the linear movement is defined by a support bearing and by a further contact point
wherein the wiper-blade-side fastening part has a cavity and has an opening arranged in a side wall of the cavity, and wherein the wiper-blade-side fastening part has guide elements arranged in the cavity and the contact point.

2. The window wiper device ( 100 ) as claimed in claim 1 , furthermore comprising:
the fastening element ( 50 ), wherein the fastening element ( 50 ) has an actuating device ( 21 ) which is configured to releasably lock the fastening element to the wiper blade-side fastening part.

3. The window wiper device ( 100 ) as claimed in claim 2 , wherein the actuating device ( 21 ) is arranged between a head part and one of the multiple connecting elements.

4. A method ( 200 ) for the mounting of a window wiper device, comprising:
providing ( 201 ) a window wiper device ( 100 ) as claimed in claim 2 ,
pushing the wiper-blade-side fastening part ( 20 ) onto the fastening element ( 50 ) in a linear movement in order to realize an engagement action between the wiper-blade-side fastening part and the fastening element ( 50 ).

5. The method as claimed in claim 4 , wherein, during the pushing-on movement, the actuating device is guided into the opening.

6. The window wiper device as claimed in claim 1 , wherein the wiper-blade-side fastening part is formed in one piece.

7. The window wiper device as claimed in claim 1 , wherein the wiper-blade-side fastening part is configured to be provided by way of an injection molding process.

8. The window wiper device as claimed in claim 1 , wherein the wiper-blade-side fastening part is formed so as to be free from metal and/or without movable elements.

9. The window wiper device ( 100 ) as claimed in claim 1 , wherein the wiper-blade-side fastening part is configured to permit a rotation relative to the fastening element about an axis perpendicular to the longitudinal extent of the wiper blade and perpendicular to the linear movement relative to the fastening element ( 50 ).

10. The window wiper device ( 100 ) as claimed in claim 9 , wherein the rotation of the fastening part relative to the fastening element is restricted to an angle range of 30° or less.

11. The window wiper device ( 100 ) as claimed in claim 9 , furthermore comprising:
a force-generating element, wherein the force-generating element is configured to effect the rotation relative to the fastening element about an axis perpendicular to the longitudinal extent of the wiper blade and perpendicular to the linear movement relative to the fastening element.

12. The window wiper device ( 100 ) as claimed in claim 9 , furthermore comprising:
a spring, wherein the spring is configured to effect the rotation relative to the fastening element about an axis perpendicular to the longitudinal extent of the wiper blade and perpendicular to the linear movement relative to the fastening element.

13. The window wiper device ( 100 ) as claimed in claim 1 , wherein the multiple connecting elements are connected at multiple upper connecting positions to the upper part and at multiple lower corresponding connecting positions to the lower part, and wherein, during the movement of the upper part and of the lower part relative to one another, the spacing between an upper connecting position and a corresponding lower connecting position is substantially constant.

14. The window wiper device ( 100 ) as claimed in claim 1 , wherein the side wall faces toward a connecting element.

15. The window wiper device as claimed in claim 1 , wherein the wiper-blade-side fastening part is configured to be provided by way of an injection molding process with one step.

16. The window wiper device ( 100 ) as claimed in claim 1 , wherein the wiper-blade-side fastening part is configured to permit a rotation relative to the fastening element about an axis perpendicular to the longitudinal extent of the wiper blade and perpendicular to the linear movement relative to the fastening element ( 50 ), wherein the support bearing forms a fulcrum of a lever for the rotation.

17. The window wiper device ( 100 ) as claimed in claim 1 , wherein the multiple connecting elements are connected at multiple upper connecting positions to the upper part and at multiple lower corresponding connecting positions to the lower part, and wherein, during the movement of the upper part and of the lower part relative to one another, the spacing between an upper connecting position and a corresponding lower connecting position is constant with a deviation of ±1 mm.
