Abstract

The invention relates to a wiper blade device comprising at least one spring strip ( 10 a - e ), at least one wiper strip support ( 12 a - e ) and at least one end sealing unit ( 14 a - e ). According to the invention, the end sealing unit ( 14 a - e ) comprises at least two detent elements ( 16 a - e , 18 a - e ) for fixing the spring strip ( 10 a - e ) and/or the wiper strip support ( 12 a - e ).

First claim

What is claimed is:

1. A wiper blade device comprising at least one spring strip ( 10 a - e ), at least one wiper strip support ( 12 a - e ) and at least one end termination unit ( 14 a - e ), characterized in that the end termination unit ( 14 a - e ) comprises at least one first latching element ( 20 a , 20 b ) that latches the end termination unit ( 14 a - e ) to the spring strip ( 10 a - e ) and at least one second latching element ( 16 a - e , 18 a - e ) that latches the end termination unit ( 14 a - e ) to the wiper strip support ( 12 a - e ), wherein the spring strip ( 10 a - e ) extends along a longitudinal direction and defines a first latching aperture ( 78 a ) enclosed entirely by the spring strip ( 10 a - e ), wherein the at least one first latching element ( 20 a , 20 b ) is disposed on the end termination unit ( 14 a - e ) and is configured to press downward into the first latching aperture ( 78 a ) along a direction that is perpendicular to the longitudinal direction, wherein the wiper strip support ( 12 a e ) includes second and third latching apertures ( 82 a , 84 a ), wherein the at least one second latching element ( 16 a - e , 18 a - e ) includes a plurality of latching elements ( 16 a - e , 18 a - e ) disposed on the end termination unit ( 14 a - e ) that are configured to press into the second and third latching apertures ( 82 a, 84 a ) along directions that are perpendicular to the longitudinal direction and perpendicular to the direction in which the first latching element ( 20 a ) presses into the first latching aperture ( 78 ).

2. The wiper blade device as claimed in claim 1 , characterized in that the at least one first and the at least one second latching elements ( 16 a - e , 18 a - e , 20 a ; 20 b ) are each formed on the end termination unit ( 14 a - e ).

3. The wiper blade device as claimed in claim 1 , characterized in that the at least one second latching element ( 16 a - e , 18 a - e ) is arranged in at least one side region ( 22 a - e , 24 a - e ) of the end termination unit ( 14 a - e ).

4. The wiper blade device as claimed in claim 1 , characterized in that at least one of the at least one first and the at least one second latching elements ( 16 a - e , 18 a - e , 20 a ; 20 b ) is designed as a latching hook ( 26 a - e , 28 a - e , 30 a ; 30 b ).

5. The wiper blade device at least as claimed in claim 4 , characterized in that the end termination unit ( 14 c ; 14 d ) has at least one aperture ( 32 c , 34 c ; 32 d , 34 d ) to increase flexibility of the latching hook ( 26 c , 28 c; 26 d , 28 d ).

6. The wiper blade device as claimed in claim 1 , characterized in that the end termination unit ( 14 a - e ) has a receiving region ( 36 a - e ) for a wiper strip ( 38 a - e ), which region, in an assembled state, continues a receiving region ( 40 a - e ), arranged on the wiper strip support ( 12 a - e ), for the wiper strip ( 38 a - e ).

7. The wiper blade device as claimed in claim 6 further comprising a wiper strip received in the receiving region ( 36 a - e ) of the end termination unit and in the receiving region ( 40 a - e ) of the wiper strip support ( 12 a - e ).

8. The wiper blade device as claimed in claim 1 , characterized in that the wiper strip support ( 12 a - e ) has at least one latching element ( 42 a - d , 44 a - d ) for fastening the end termination unit ( 14 a - d ) to the wiper strip support ( 12 a - d ).

9. A wiper blade ( 46 a - e ) having a wiper blade device as claimed in claim 1 .

10. The wiper blade device as claimed in claim 1 , wherein the at least one first latching element ( 20 a , 20 b ) is latched to the spring strip ( 10 a - e ) and the at least one second latching element ( 16 a - e , 18 a - e ) is latched to the wiper strip support ( 12 a - e ).

11. The wiper blade device as claimed in claim 1 , wherein the wiper strip support ( 12 a - e ) defines a longitudinal guide channel, wherein the spring strip ( 10 a - e ) extends through the longitudinal guide channel.
