Abstract

The invention relates to a wiper blade device comprising a wiper blade adapter ( 10 ) and a wiper strip unit ( 12 ). According to the invention, said wiper strip unit ( 12 ) has at least one securing recess ( 14 ) which, in at least one operating state, forms an interlocking connection with the wiper blade adapter ( 10 ).

First claim

What is claimed is:

1. A wiper blade device having a wiper blade adapter ( 10 ) and having a wiper strip unit ( 12 ), characterized in that the wiper strip unit ( 12 ) has at least one fastening recess ( 14 ) which, in at least one operating state, forms a positive fit with the wiper blade adapter ( 10 ), wherein the wiper strip unit includes a rest body ( 42 ) arranged centrally in the fastening recess, and wherein the wiper blade adapter has a central recess ( 40 ) which, in an assembled state, forms a positive fit with the rest body, wherein the wiper strip unit ( 12 ) extends along a longitudinal axis, wherein the central recess ( 40 ), in a pre-assembled state, extends over the rest body ( 42 ) and forms the positive fit with the rest body ( 42 ), such that the wiper blade adapter ( 10 ) is prevented from moving relative to the wiper strip unit ( 12 ) along the longitudinal axis due to the positive fit with the rest body ( 42 ) and with the fastening recess ( 14 ), but is otherwise able to be detached from the wiper strip unit ( 12 ), and wherein the wiper strip unit ( 12 ) has at least one resiliently elastic carrier element ( 46 ) which, in an assembled state, has been passed through the wiper blade adapter ( 10 ) and forms a positive fit with the wiper blade adapter ( 10 ) in order to prevent a movement of the carrier element ( 46 ) within a longitudinal guide channel ( 26 ) of the wiper strip unit ( 12 ) in all directions.

2. The wiper blade device as claimed in claim 1 , characterized in that the wiper blade adapter ( 10 ) has at least one fastening means ( 16 ) which, in at least one operating state, forms a positive fit with a wind deflector element ( 20 ) of the wiper strip unit ( 12 ) and prevents a movement of the wiper strip unit ( 12 ) relative to the wiper blade adapter ( 10 ) in a longitudinal direction ( 18 ).

3. The wiper blade device as claimed in claim 1 , characterized in that the carrier element ( 46 ) has at least one detent means ( 48 ) which, in at least one operating state, forms a detent connection with the wiper blade adapter ( 10 ).

4. The wiper blade device as claimed in claim 1 , characterized in that the wiper strip unit ( 12 ) has a wind deflector element ( 20 ) and a wiper lip ( 22 ) which are formed in one piece.

5. The wiper blade device as claimed in claim 1 , characterized in that the wiper blade adapter ( 10 ) has a longitudinal guide unit ( 24 ) which receives the carrier element ( 46 ) with a positive fit.

6. A method for assembling a wiper blade device as claimed in claim 1 , characterized in that the wiper blade adapter ( 10 ) is mounted onto the wiper strip unit ( 12 ), wherein at least one fastening means ( 16 ) of the wiper blade adapter ( 10 ) engages into the fastening recess ( 14 ) with a positive fit.

7. The wiper blade device as claimed in claim 1 , wherein the rest body ( 42 ) has a larger width than a remainder of the wiper strip unit ( 12 ) in an area of the fastening recess ( 14 ), the width being measured along a direction that is perpendicular to the longitudinal axis.

8. The wiper blade device as claimed in claim 1 , wherein the rest body ( 42 ) is integrally formed as part of the wiper strip unit ( 12 ).

9. The wiper blade device as claimed in claim 1 , wherein the rest body ( 42 ) has a generally rectangular cross-sectional shape.

10. The wiper blade device as claimed in claim 1 , wherein the wiper blade adapter ( 10 ) directly contacts the elastic carrier element ( 46 ).

11. The wiper blade device as claimed in claim 1 , wherein the elastic carrier element ( 46 ) includes detent recesses ( 50 ), and wherein the wiper blade adapter ( 10 ) includes detent hooks ( 38 ) that extend into the detent recesses ( 50 ).

12. The wiper blade device as claimed in claim 11 , wherein each of the detent hooks ( 38 ) wraps around a portion of a top side and a bottom side of the elastic carrier element ( 46 ).
