Abstract

The invention relates to a wiper device for a motor vehicle window, comprising a wiper arm adapter unit (10a - 10e) and a wiper blade adapter unit (12a-12e), which in an installed state create a form fit, and further comprising a longitudinal guide unit (20a-20e) for guiding the wiper arm adapter unit (10a-10e). According to the invention, the wiper device comprises a locking means (14a-14e) which is movably mounted on the wiper blade adapter unit (12a-12e) and is provided so as to limit the freedom of movement of the wiper arm adapter unit (10a-10e) in the installed state at least substantially in a longitudinal direction (16a-16e).

Claims

1. A wiper device for a motor vehicle window, comprising a wiper arm adapter unit (10a-10e) and a wiper blade adapter unit (12a-12e), which in an installed state create a form fit, and further comprising a longitudinal guide unit (20a-20e) for guiding the wiper arm adapter unit (10a-10e), characterized by a locking means (14a-14e) which is movably mounted on the wiper blade adapter unit (12a-12e) and is provided so as to limit the freedom of movement of the wiper arm adapter unit (10a-10e) in the installed state at least substantially in a longitudinal direction (16a-16e).

2. The wiper device according to claim 1, characterized in that the locking means (14a-14e) is embodied as detent means (18a-18e).

3. The wiper device according to claim 2, characterized in that the detent means (18a-18e) is integrally formed with a base body (22a-22e) of the wiper blade adapter unit (12a-12e).

4. The wiper device according to claim 3, characterized in that the detent means (18b;

18c) is provided so as to be deflected during installation at least substantially parallel to a transverse direction (46b;

46c) of a base body (22b;

22c) of the wiper blade adapter unit (12b;

12c).

5. The wiper device according to claim 3, characterized in that the detent means (18a;

18d;

18e) is provided so as to be deflected during installation at least substantially parallel to a vertical direction (44a;

44d;

44e) of a base body (22a;

22d;

22e) of the wiper blade adapter unit (12a;

12d;

12e).

6. The wiper device according to claim 1, characterized by a covering (38a-38e) which in at least one operating state is formed at least for the most part by the wiper arm adapter unit (10a-10e).

7. The wiper blade adapter unit of a wiper device according to claim 1.

8. A wiper blade comprising a wiper blade adapter unit according to claim 7.

9. The wiper device according to claim 4, characterized by a covering (38a-38e) which in at least one operating state is formed at least for the most part by the wiper arm adapter unit (10a-10e).
