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

What is claimed is:

1. A windshield wiping device comprising:
a mounting unit ( 41 , 60 ), 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 such that the wiper blade ( 2 ) is fastened to the mounting unit ( 41 , 60 ) by a single movement essentially perpendicular to both the lengthwise dimension ( 8 ) and to a vertical dimension, wherein the vertical dimension is perpendicular to a windshield;
wherein the first engagement element ( 42 ) includes a recess having a trapezoidal shape, and the second engagement element ( 44 ) includes a projection having a trapezoidal shape, such that the first engagement element ( 42 ) and the second engagement element ( 44 ) are interlocked with one another in a positive engagement when the projection is slid into the recess.

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 ) also form a force closure.

3. 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 ).

4. The windshield wiping device ( 40 ) as claimed in claim 1 , wherein the recess extends entirely through the mounting unit ( 41 ).

5. The windshield wiping device ( 40 ) as claimed in claim 4 , wherein the recess extends from one side wall of the mounting unit ( 41 ) to an opposite side wall of the mounting unit ( 41 ).

6. A windshield wiping device comprising:
a mounting unit ( 41 , 60 ), 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 ), wherein the first engagement element and the second engagement element are each trapezoidal-shaped.
