Abstract

The present invention relates to a windscreen wiping device ( 40, 50 ) for a vehicle having an attachment element, in particular a motor vehicle. The windscreen wiping device ( 40, 50 ) comprises a mounting unit ( 41, 60 ) which is designed to be mounted on the attachment element, wherein the mounting unit ( 41, 60 ) has a first engagement element ( 42, 61 ), and a wiper blade ( 2 ) having an elongate upper part ( 10 ) and an elongate lower part ( 12 ) that are designed to be flexible at least in part. Also provided are a plurality of connecting elements ( 18 ) for connecting the upper part ( 10 ) and the lower part ( 12 ), wherein the connecting elements ( 18 ) are spaced apart from one another along a longitudinal extension ( 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 an attachment part ( 43, 51 ) on the wiper blade, wherein the attachment part ( 43, 51 ) on the wiper blade has a second engagement element ( 44, 52 ), and wherein the first engagement element ( 42, 61 ) and the second engagement element ( 44, 52 ) can be introduced one into the other by a movement substantially perpendicular to the longitudinal extension ( 8 ).

First claim

1 . A windshield wiping device ( 40 , 50 ) for a vehicle with a fastening element, comprising:
a mounting unit ( 41 , 60 ), which is configured to be mounted on the fastening element, wherein the mounting unit ( 41 , 60 ) has a first engagement element ( 42 , 61 ), and a wiper blade ( 2 ) with
an elongated upper part ( 10 ), which is at least partly bendable,
an elongated lower part ( 12 ), which is at least partly bendable,
a plurality of connection elements ( 18 ) connecting the upper part ( 10 ) and the lower part ( 12 ), wherein the connection elements ( 18 ) are spaced apart from each other along a lengthwise dimension ( 8 ) of the wiper blade ( 2 ), and wherein the connection elements ( 18 ) are configured to enable a movement of the upper part ( 10 ) and the lower part relative to each other with a movement component along the lengthwise dimension ( 8 ) of the wiper blade ( 2 ), and
a wiper blade-side fastening part ( 43 , 51 ) at a wiper blade side, wherein the wiper blade-side fastening part ( 43 , 51 ) has a second engagement element ( 44 , 52 ), and wherein the first engagement element ( 42 , 61 ) and the second engagement element ( 44 , 52 ) are configured to be introduced into one another by a movement essentially perpendicular to the lengthwise dimension ( 8 ).

2 . The windshield wiping device ( 40 , 50 ) as claimed in claim 1 , wherein the first engagement element ( 42 , 61 ) and the second engagement element ( 44 , 52 ) form at least one of a positive engagement and a force closure.

3 . The windshield wiping device ( 50 ) as claimed in claim 2 , wherein the mounting unit comprises an activating device ( 64 ), which is configured to make and/or break the force closure and/or positive engagement.

4 . The windshield wiping device ( 40 ) as claimed in claim 1 , wherein the first engagement element ( 42 ) and the second engagement element ( 44 ) are designed essentially in dovetail manner.

5 . The windshield wiping device ( 50 ) as claimed in claim 1 , wherein the mounting unit ( 60 ) further has a mounting element ( 63 ), wherein the second engagement element ( 52 ) of the fastening part ( 53 ) at the wiper blade side after being inserted is positioned between the first engagement element ( 61 ) and the mounting element ( 63 ).

6 . The windshield wiping device ( 50 ) as claimed in claim 5 , wherein a force closure and/or positive engagement between the first engagement element ( 61 ) and the second engagement element ( 52 ) and/or between the second engagement element ( 52 ) and the mounting element ( 63 ) is created by a movement of the first engagement element ( 61 ) relative to the mounting element ( 63 ) in a direction which is essentially perpendicular to the lengthwise dimension ( 8 ) of the wiper blade ( 2 ), and/or which is essentially perpendicular to the direction of the movement by which the first engagement element ( 61 ) and the second engagement element ( 52 ) are introduced into one another.

7 . The windshield wiping device ( 50 ) as claimed in claim 5 , wherein the mounting unit ( 60 ) further comprises a connection element ( 62 ) which joins together the first engagement element ( 61 ) and the mounting element ( 63 ).

8 . The windshield wiping device ( 50 ) as claimed in claim 7 , wherein the connection element ( 62 ) is U-shaped.

9 . The windshield wiping device ( 50 ) as claimed in claim 8 , wherein one leg of the U-shaped connection element ( 62 ) is configured to be inserted into the first engagement element ( 61 ), and/or another leg of the U-shaped connection element ( 62 ) is configured to be inserted into the mounting element ( 63 ).

10 . The windshield wiping device ( 50 ) as claimed in claim 5 , wherein the first engagement element ( 61 ) is cylindrical in form, and the second engagement element ( 52 ) is essentially a half-shell.

11 . The windshield wiping device ( 50 ) as claimed in claim 10 , wherein one leg of the U-shaped connection element ( 62 ) is configured be inserted into the first engagement element ( 61 ) at a distance from a cylinder axis of the first engagement element.

12 . The windshield wiping device ( 50 ) as claimed in claim 11 , wherein the force closure and/or positive engagement between the first engagement element ( 61 ) and the second engagement element ( 52 ) and/or between the second engagement element ( 52 ) and the mounting element ( 63 ) is produced by a rotation of the first engagement element ( 61 ) about the cylinder axis.

13 . A method ( 70 ) for the mounting of a windshield wiping device, the method comprising:
providing ( 71 ) a windshield wiping device ( 40 , 50 ) as claimed in claim 1 , introducing the first engagement element ( 42 , 61 ) and the second engagement element ( 44 , 52 ) into one another by a movement essentially perpendicular to the lengthwise dimension ( 8 ) of the wiper blade ( 2 ).
