Abstract

The present invention relates to a windscreen wiper device (100) for a vehicle, with a fastening element (50). The windshield wiper device (100) includes a wiper blade (2) with an elongated upper part (10) and an elongated lower part (12) which is at least partially designed to bend. Furthermore, a plurality of connecting elements (18) for connecting the upper part (10) and the lower part (12) is provided, wherein the connecting elements (18) are spaced apart along a longitudinal extension (8) of the wiper blade (2). The connecting elements (18) are designed to enable a movement of the upper part (10) and 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 fastening element (20) comprises a securing element (22) into which the fastening element (50) is insertable and which is designed to engage the fastening element (50) to force-fit or form-fit.

First claim

What is claimed is:

1. A windshield wiper device ( 100 ) for a vehicle with a fastening element ( 50 ), the device comprising a wiper blade ( 2 ) with
an elongate upper part ( 10 ), which is configured to be at least partially bendable,
an elongate lower part ( 12 ), which is configured to be at least partially bendable,
a plurality of 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 the lower part relative to each other with a movement component along the longitudinal extent ( 8 ), and
a wiper-blade-side fastening part ( 20 ), wherein the wiper-blade-side fastening part ( 20 ) has a generally U-shaped securing element ( 22 ) in the form of a retaining spring which is configured to receive the fastening element ( 50 ) and which is configured to form a non-positively locking connection and/or positively locking connection with the fastening element ( 50 ), wherein the generally U-shaped securing element ( 22 ) has a closed end ( 24 ) and two arms defining an opposite, open end, wherein the wiper-blade-side fastening part ( 200 ) has an actuating device ( 21 ) which is configured to release the non-positively locking connection and/or positively locking connection, wherein the actuating device ( 21 ) is positioned at the open end and is configured to move generally parallel to the two arms in a direction toward the closed end ( 24 ) when activated to spread and separate the two arms.

2. The windshield wiper device ( 100 ) as claimed in claim 1 , wherein the securing element ( 22 ) has an opening ( 23 ) configured to have the fastening element ( 50 ) inserted therein.

3. The windshield wiper device ( 100 ) as claimed in claim 2 , wherein the size of the opening ( 23 ) is variable.

4. The windshield wiper device ( 100 ) as claimed in claim 3 , wherein circumferential, circular-shaped regions of the opening ( 23 ) are configured to form the non-positively locking connection and/or positively locking connection with the fastening element ( 5 ).

5. The windshield wiper device ( 100 ) as claimed in claim 4 , wherein the wiper-blade-side fastening part ( 20 ) has an actuating device ( 21 ) which is configured to release the non-positively locking connection and/or positively locking connection.

6. The windshield wiper device ( 100 ) as claimed in claim 5 , wherein the actuating device ( 21 ) is configured to change the size of the opening ( 23 ) upon an actuation.

7. The windshield wiper device ( 100 ) as claimed in claim 6 , wherein the securing element ( 22 ) is configured to engage in a depression ( 51 ) of the fastening element ( 50 ) in order to form the non-positively locking connection and/or positively locking connection.

8. The windshield wiper device ( 100 ) as claimed in claim 2 , wherein circumferential, circular-shaped regions of the opening ( 23 ) are configured to form the non-positively locking connection and/or positively locking connection with the fastening element ( 5 ).

9. The windshield wiper device ( 100 ) as claimed in claim 2 , wherein the actuating device ( 21 ) is configured to change the size of the opening ( 23 ) upon an actuation.

10. The windshield wiper device ( 100 ) as claimed in claim 1 , wherein the wiper-blade-side fastening part ( 20 ) has an actuating device ( 21 ) which is configured to release the non-positively locking connection and/or positively locking connection.

11. The windshield wiper device ( 100 ) as claimed in claim 1 , wherein the securing element ( 22 ) is configured to engage in a depression ( 51 ) of the fastening element ( 50 ) in order to form the non-positively locking connection and/or positively locking connection.

12. A method ( 200 ) for mounting a windshield wiper device, comprising:
providing ( 201 ) the windshield wiper device ( 100 ) as claimed in claim 1 , and
fastening ( 202 ) the wiper-blade-side fastening part ( 20 ) to the fastening element ( 50 ) by forming the non-positively locking connection and/or positively locking connection between the securing element ( 22 ) and the fastening element ( 50 ).

13. The windshield wiper device ( 100 ) as claimed in claim 1 , wherein the securing element ( 22 ) is configured such that when the securing element ( 22 ) is locked to the fastening element ( 50 ), the securing element ( 22 ) is held against longitudinal movement in a longitudinal direction of the fastening element ( 50 ).

14. The windshield wiper device ( 100 ) as claimed in claim 1 , wherein the securing element ( 22 ) is configured such that when the securing element ( 22 ) is locked to the fastening element ( 50 ), a positive locking connection to the fastening element ( 50 ) is formed.

15. The windshield wiper device ( 100 ) as claimed in claim 1 , further comprising the fastening element ( 50 ), wherein the fastening element ( 50 ) includes an intersection ( 53 ) that facilitates a transmission of torque from the fastening element ( 50 ) to the wiper blade ( 2 ).
