Abstract

The invention relates to a windshield wiper device (100) for a vehicle, having a fastening element (32) and a mounting unit (110) configured to be mounted to the fastening element (32), wherein the mounting unit (110) has a first engagement means (116). The windshield wiper device (100) comprises a wiper blade (2) having a longitudinal extension (8), wherein on the wiper blade side, the wiper blade (2) is provided with a fastening part (120) having a second engagement means (124). The mounting unit (110) and the fastening part (120) on the wiper blade side can be inserted into each other, at least partially, by a movement substantially along the longitudinal extension (8) of the wiper blade (2). The first engagement means (116) and the second engagement means (124) are designed to engage with one another, whenever the mounting unit (110) and the fastening part (120) on the wiper blade side are inserted into each other. The engagement between the first engagement means (116) of the mounting unit (110) and the second engagement means (124) of the fastening part (120) on the wiper blade side can be released.

First claim

What is claimed is:

1. A windshield wiper device ( 100 ) for a vehicle having a fastening element ( 32 ) and a mounting unit ( 110 ) which is configured for being mounted on the fastening element ( 32 ), the mounting unit ( 110 ) having a first engagement means ( 116 ), the windshield wiper device ( 100 ) comprising:
a wiper blade ( 2 ) with a longitudinal extent ( 8 ), the wiper blade ( 2 ) having a wiper blade-side fastening part ( 120 ) with a second engagement means ( 124 ), the mounting unit ( 110 ) and the wiper blade-side fastening part ( 120 ) being configured to be introduced at least partially into one another by a movement substantially along the longitudinal extent ( 8 ) of the wiper blade ( 2 ), the first engagement means ( 116 ) and the second engagement means ( 124 ) being configured for engaging into one another when the mounting unit ( 110 ) and the wiper blade-side fastening part ( 120 ) are introduced into one another, and the engagement between the first engagement means ( 116 ) of the mounting unit ( 110 ) and the second engagement means ( 124 ) of the wiper blade-side fastening part ( 120 ) being releasable, the wiper blade ( 2 ) further including an elastic element ( 128 ) which is arranged between surfaces facing one another of the wiper blade-side fastening part ( 120 ) and a remainder of the wiper blade ( 2 ) and which is configured to push a portion of the wiper blade-side fastening part ( 120 ) away from the remainder of the wiper blade ( 2 ) along the longitudinal extent ( 8 ), the wiper blade ( 2 ) further including a rotary joint ( 126 ) spaced from and to one side only of the elastic element ( 128 ) along a direction perpendicular to the longitudinal extent ( 8 ), wherein the rotary joint ( 126 ) connects the wiper blade-side fastening part ( 120 ) and the remainder of wiper blade ( 2 ) rotatably to each other.

2. The windshield wiper device ( 100 ) as claimed in claim 1 , the wiper blade ( 2 ) comprising:
an elongate upper part ( 10 ) which is of at least partially flexible configuration,
an elongate lower part ( 12 ) which is of at least partially flexible configuration, and
a plurality of connecting elements ( 18 ) for connecting the upper part ( 10 ) and the lower part ( 12 ), the connecting elements ( 18 ) being spaced apart from one another along the longitudinal extent ( 8 ) of the wiper blade ( 2 ) and being attached on the upper part ( 10 ) and/or on the lower part ( 12 ) by means of a further rotary joint ( 20 ).

3. The windshield wiper device ( 100 ) as claimed in claim 2 , the connecting elements ( 18 ) being configured for making a movement of the upper part ( 10 ) and the lower part ( 12 ) relative to one another possible with a movement component along the longitudinal extent ( 8 ) of the wiper blade ( 2 ).

4. The windshield wiper device ( 100 ) as claimed in claim 1 , the mounting unit ( 110 ) having a first opening ( 114 ), through which the wiper blade-side fastening part ( 120 ) is configured to be introduced at least partially into the mounting unit ( 110 ).

5. The windshield wiper device ( 100 ) as claimed in claim 4 , the first engagement means ( 116 ) being a second opening, a circumferential region of the second opening being configured for engaging with the second engagement means ( 124 ).

6. The windshield wiper device ( 100 ) as claimed in claim 1 , comprising an actuating apparatus, engagement between the first engagement means ( 116 ) of the mounting unit ( 110 ) and the second engagement means ( 124 ) of the wiper blade-side fastening part ( 120 ) being releasable by an actuation of the actuating apparatus.

7. The windshield wiper device ( 100 ) as claimed in claim 6 , the actuating apparatus comprising the first engagement means ( 116 ) or the second engagement means ( 124 ).

8. The windshield wiper device ( 100 ) as claimed in claim 6 , the actuating apparatus being configured as a button or pushbutton.

9. The windshield wiper device ( 100 ) as claimed in claim 6 , the actuating apparatus comprising the first engagement means ( 116 ) or the second engagement means ( 124 ), and the actuating apparatus and the first engagement means ( 116 ) or the second engagement means ( 124 ) being configured in one piece.

10. The windshield wiper device ( 100 ) as claimed in claim 1 , wherein the wiper blade-side fastening part ( 120 ) is arranged on the wiper blade ( 2 ) so as to be rotatable about an axis of rotation.

11. The windshield wiper device ( 100 ) as claimed in claim 1 , the elastic element ( 128 ) comprising a compression spring configured to push the portion of the wiper blade-side fastening part ( 120 ) away from the wiper blade ( 2 ) along the longitudinal extent ( 8 ).

12. A method ( 700 ) for mounting a windshield wiper device ( 100 ) as claimed in claim 1 , comprising:
introducing the mounting unit ( 110 ) and the wiper blade-side fastening part ( 120 ) at least partially into one another by a movement substantially along the longitudinal extent ( 8 ) of the wiper blade ( 2 ); and
forming a non-positive connection and/or positively locking connection between the first engagement means ( 116 ) and the second engagement means ( 124 ).

13. A method for dismantling a windshield wiper device ( 100 ) as claimed in claim 1 , comprising:
releasing a non-positive connection and/or positively locking connection between the first engagement means ( 116 ) and the second engagement means ( 124 ); and
moving the mounting unit ( 110 ) and the wiper blade-side fastening part ( 120 ) apart from one another in a direction substantially along the longitudinal extent ( 8 ) of the wiper blade ( 2 ), in order to release the mounting unit ( 110 ) and the wiper blade-side fastening part ( 120 ) from one another.

14. The windshield wiper device ( 100 ) as claimed in claim 1 , further comprising the mounting unit, the first engagement means ( 116 ) being a second opening, a circumferential region of the second opening being configured for engaging with the second engagement means ( 124 ) and for forming a non-positive and/or positively locking connection with the second engagement means ( 124 ).

15. The windshield wiper device ( 100 ) as claimed in claim 1 , wherein the wiper blade-side fastening part ( 120 ) is arranged on the wiper blade ( 2 ) so as to be rotatable about an axis of rotation, wherein the axis of rotation is substantially perpendicular to the longitudinal extent ( 8 ) of the wiper blade ( 2 ).

16. The windshield wiper device ( 100 ) as claimed in claim 15 , wherein the rotary joint ( 126 ) connects the wiper blade-side fastening part ( 120 ) and the wiper blade ( 2 ) rotatably to each other, and wherein the rotary joint ( 126 ) provides the axis of rotation.
