Abstract

The present invention relates to a window-wiping device (100) for a vehicle, comprising a wiper blade (2) having an elongate upper part (10) and an elongate lower part (12), which are designed to be at least partially flexible. Also provided is a plurality of connecting elements (18) for connecting the upper part (10) and the lower part (12), the connecting elements (18) being spaced apart along a longitudinal extent (8) of the wiper blade (2) and being attached to the upper part (10) and/or the lower part (12) by a rotary joint, and the connecting elements (18) being designed to allow a motion of the upper part (10) and the lower part relative to each other with a motion component along the longitudinal extent (8) of the wiper blade (2). The window-wiping device also has a wiper-blade-side fastening part (30), which is accommodated in the wiper blade head (70), and a fastening element (50), which can be attached to the drive shaft (33) and into which the wiper-blade-side fastening part (30) can be locked and which has an actuating device (21), which is designed to release the wiper-blade-side fastening part (30) from the fastening element (50) as a result of an actuation, wherein the actuating device (21) has a blocking element (22), which is designed to block actuation of the actuating device (21).

wherein the window wiper device furthermore comprises:
a wiper-blade-side fastening part ( 30 ) which is accommodated in the wiper blade head ( 70 ) and which is configured for connecting the wiper arm ( 1 ) detachably to a drive shaft ( 33 ) of a drive unit ( 32 ) of the vehicle, and
a fastening element ( 50 ) which is attachable to the drive shaft ( 33 ) and into which the wiper-blade-side fastening part ( 30 ) can be engaged and which has an actuating device ( 21 ) which is configured such that, when actuated, the actuating device releases the wiper-blade-side fastening part ( 30 ) from the fastening element ( 50 ), wherein the actuating device ( 21 ) has a blocking element ( 22 ) which is configured to block an actuation of the actuating device ( 21 ), wherein the wiper-blade-side fastening part ( 30 ) has a hollow chamber and has an opening ( 210 ) arranged in a side wall of the hollow chamber, wherein the opening ( 210 ) is arranged in a side wall of the hollow chamber which faces toward the connecting elements ( 18 ).

2. The window wiper device as claimed in claim 1 , wherein the blocking element ( 22 ) is in the form of a lock cylinder ( 43 ) integrated into the actuating device ( 21 ).

3. The window wiper device as claimed in claim 1 , wherein the blocking element
( 22 ) is in the form of a combination lock ( 40 ) integrated into the actuating device ( 21 ).

4. The window wiper device as claimed in claim 1 , wherein the blocking element ( 22 ) is in the form of a rotary lock ( 38 ) integrated into the actuating device ( 21 ).

5. The window wiper device as claimed in claim 1 , wherein the wiper-blade-side fastening part ( 30 ) is formed integrally with the wiper blade head ( 70 ) of the window wiper device.

6. The window wiper device as claimed in claim 1 , wherein the wiper blade head ( 70 ) comprises a material selected from the group comprising rubber, carbon, POM, PA, TPE, or any combination thereof.

7. The window wiper device as claimed in claim 1 , wherein the actuating device ( 21 ) and/or the associated blocking element ( 22 ) is arranged between the wiper blade head ( 70 ) and one of the multiple connecting elements ( 18 ).

8. A method for dismounting a window wiper device for a vehicle as claimed in claim 1 , comprising:
releasing the blocking element ( 22 ), and
actuating the actuating device ( 21 ) for the purposes of separating the wiper-blade-side fastening part from the fastening element.

9. The window wiper device as claimed in claim 1 , wherein the wiper blade head ( 70 ) comprises a material selected from the group comprising rubber, carbon, POM, PA, TPE-S, TPE-O, TPE-U, TPE-A, TPE-V and TPE-E, or any combination thereof.

10. A window wiper device for a vehicle, comprising a wiper arm ( 1 ) with a wiper blade head ( 70 ) and a wiper blade ( 2 ), which comprises
