Abstract

The present invention relates to a windscreen wiper device ( 100 ) for a vehicle, with a fastening element ( 52 ), in particular to a motor vehicle. The windscreen wiper device ( 100 ) comprises a mounting element ( 40 ) which is designed to be mounted on the fastening element ( 52 ), and a wiper blade ( 2 ) with an elongate upper part ( 10 ) and an elongate lower part ( 12 ), which are configured to be at least partially bendable. Furthermore, a plurality of connecting elements ( 18 ) for connecting the upper part ( 10 ) and the lower part ( 12 ) are provided, wherein the connecting elements ( 18 ) are spaced apart from one another along a longitudinal extent ( 8 ) of the wiper blade ( 2 ). The connecting elements ( 18 ) are designed to permit a movement of the upper part ( 10 ) and of the lower part ( 12 ) relative to one another with a movement component along a longitudinal extension ( 8 ) of the wiper blade ( 2 ). Furthermore, the wiper blade ( 2 ) comprises a wiper-blade-side fastening part ( 20 ). The wiper-blade-side fastening part ( 20 ) is configured in such a manner that, by means of a rotation of the wiper-blade-side fastening part ( 20 ) relative to the mounting element ( 40 ), an engagement can be formed in order to connect the wiper-blade-side fastening part ( 20 ) to the mounting element ( 40 ).

2. The windshield wiper device ( 100 ) as claimed in claim 1 , wherein the securing element ( 41 ) is configured as a recess in a lateral surface of the mounting element ( 40 ).

3. The windshield wiper device ( 100 ) as claimed in claim 1 , wherein the mounting element ( 40 ) has at least one engagement element which is configured in order to form an engagement with at least one securing element of the wiper-blade-side fastening part ( 20 ).

4. The windshield wiper device ( 100 ) as claimed in claim 3 , wherein the securing element is configured as a recess in a lateral surface of the wiper-blade-side fastening part ( 20 ).

5. The windshield wiper device ( 100 ) as claimed in claim 1 , wherein the mounting element ( 40 ) is of cylindrical shape.

6. The windshield wiper device ( 100 ) as claimed in claim 5 , wherein an inside diameter of the wiper-blade-side fastening part ( 21 ) substantially corresponds to an outside diameter of the mounting element ( 40 ).

7. The windshield wiper device ( 100 ) as claimed in claim 5 , wherein an inside diameter of the mounting element ( 40 ) substantially corresponds to an outside diameter of the wiper-blade-side fastening part ( 21 ).

8. The windshield wiper device ( 100 ) as claimed in claim 1 , wherein the engagement element ( 21 ) is configured in order to engage in the securing element ( 41 ) and, by rotation of the wiper-blade-side fastening part ( 20 ) relative to the mounting element ( 40 ), to be guided along the securing element ( 41 ).

9. The windshield wiper device ( 100 ) as claimed in claim 1 , wherein the engagement element ( 21 ) is configured as a projection.

10. A method ( 200 ) for mounting a windshield wiper device, comprising:
providing ( 201 ) a windshield wiper device ( 100 ) as claimed in claim 1 , and
