Abstract

The invention relates to a windshield wiper device ( 100 ) for a vehicle having a fastening element ( 52 ), in particular a motor vehicle. The windshield wiper device ( 100 ) comprises a mounting element ( 40 ), which is designed to be mounted on the fastening element ( 52 ), and a wiper blade ( 2 ) having an elongated upper part ( 10 ) and an elongated lower part ( 12 ), which parts are at least partially flexible. Furthermore, a plurality of connection elements ( 18 ) for connecting the upper part ( 10 ) and the lower part ( 12 ) are provided, wherein the connection elements ( 18 ) are spaced apart from one another along a longitudinal extension ( 8 ) of the wiper blade ( 2 ). The connection elements ( 18 ) are configured to allow a movement of the upper part ( 10 ) and the lower part ( 12 ) relative to one another with a motion component along a longitudinal extension ( 8 ) of the wiper blade ( 2 ). The wiper blade ( 2 ) further comprises a fastening part ( 20 ) on the wiper-blade side. The fastening part ( 20 ) on the wiper-blade side is configured such that by means of a movement of the fastening part ( 20 ) on the wiper-blade side relative to the mounting element ( 50 ), a first engagement can be formed in order to connect the fastening part ( 20 ) on the wiper-blade side to the mounting element ( 50 ). The windshield wiper device ( 100 ) further comprises a closure mechanism ( 52, 22 ), which is configured to fix a position of the fastening part ( 20 ) on the wiper-blade side relative to the mounting element ( 50 ) after the first engagement has been formed.

a wiper blade ( 2 ) having
an elongate upper part ( 10 ) which is at least partially of flexible form,
an elongate lower part ( 12 ) which is at least partially of flexible form,
multiple 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 of the lower part relative to one another with a movement component along the longitudinal extent ( 8 ) of the wiper blade ( 2 ),
a wiper blade-side fastening part ( 20 ), wherein the wiper blade-side fastening part ( 20 ) is configured such that, by way of a movement of the wiper blade-side fastening part ( 20 ) relative to the installation element ( 50 ), a first engagement action can be realized in order to connect the wiper blade-side fastening part ( 20 ) to the installation element ( 50 ),

wherein the wiper blade-side fastening part ( 20 ) includes at least one first engagement element ( 21 ) which is configured to realize the first engagement action with the at least one first securing element ( 51 ) of the installation element ( 50 ), wherein the at least one first engagement element ( 21 ) is a protrusion extending from a side wall of the wiper blade-side fastening part ( 20 ) and at least partially into the slot, wherein the entire slot extends in an elongate direction within a plane that is parallel to the longitudinal extent ( 8 ) and that is configured to extend perpendicular to a windshield, and wherein the first engagement action includes movement of the protrusion along the slot from the first section to the second section, such that the installation element ( 50 ) moves both linearly relatively to the wiper blade ( 2 ) along a direction parallel to the longitudinal extent ( 8 ), and also rotates relative to the wiper blade ( 2 ), and
a latch mechanism ( 52 , 22 ) which is configured to fix a position of the wiper blade-side fastening part ( 20 ) relative to the installation element ( 50 ) after the realization of the first engagement action.

2. The windshield wiper device ( 100 ) as claimed in claim 1 , wherein the first engagement element ( 21 ) forms an axis for a rotation of the wiper blade-side fastening part ( 20 ) relative to the installation element ( 50 ).

3. The windshield wiper device ( 100 ) as claimed in claim 1 , wherein the latch mechanism ( 22 , 52 ) has a second engagement element ( 22 ) and a second securing element ( 52 ), which are configured to realize, by way of the rotation of the wiper blade-side fastening part ( 20 ) about an axis of rotation that extends perpendicular to the plane, a second engagement action with one another in order to fix the position of the wiper blade-side fastening part ( 20 ) relative to the installation element ( 50 ) after the realization of the first engagement action.

4. The windshield wiper device ( 100 ) as claimed in claim 3 , wherein the second engagement element ( 22 ) is formed on the wiper blade-side fastening part ( 20 ) and the second securing element ( 52 ) is formed on the installation element ( 50 ), or wherein the second engagement element is formed on the installation element ( 50 ) and the second securing element is formed on the wiper blade-side fastening part ( 20 ).

5. The windshield wiper device ( 100 ) as claimed in claim 3 , wherein the latch mechanism device ( 22 , 52 ) has a release mechanism which is configured to eliminate the second engagement action.

6. A method ( 200 ) for the installation of a windshield wiper device, comprising:
providing ( 201 ) a windshield wiper device ( 100 ) as claimed in claim 1 , and
fastening ( 202 ) the wiper blade-side fastening part ( 20 ) to the installation element ( 50 ) by realization of the engagement action between the wiper blade-side fastening part ( 20 ) and the installation element ( 50 ) and rotation of the wiper blade-side fastening part ( 20 ) relative to the installation element ( 50 ) about an axis of rotation which runs substantially transversely with respect to the longitudinal extent ( 8 ) of the wiper blade ( 2 ), in order to fix a position of the wiper blade-side fastening part ( 20 ) relative to the installation element ( 50 ).

7. The windshield wiper device ( 100 ) as claimed in claim 1 , wherein the first linear section is longer than the second linear_section.

8. The windshield wiper device ( 100 ) as claimed in claim 1 , wherein the elongate slot is fully enclosed on all sides by the side wall of the installation element ( 50 ).

9. The windshield wiper device ( 100 ) as claimed in claim 8 , wherein the elongate slot and the side wall of the installation element ( 50 ) together define a stop, so that the projection is configured to move linearly along the first linear section, rotate through the bend, and then move linearly along the second section within the elongate slot until it reaches the stop.

10. The windshield wiper device ( 100 ) as claimed in claim 1 , wherein the installation element ( 50 ) includes a gap ( 53 ) into which a portion of the wiper blade-side fastening part is configured to extend during assembly.

11. The windshield wiper device ( 100 ) as claimed in claim 1 , wherein the bend forms an obtuse angle between the first linear section and the second linear section.
