## 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

### Claim 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) along a longitudinal direction (16a-e), 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 the longitudinal direction (16a-16e), characterized in that the locking means (14a-14e) is embodied as a detent means (18a-18e) that includes a barb (30a-30d), and in that the barb (30a-30d) is positioned on the wiper blade adapter unit (12a-12c) such that the barb (30a-30d) is engaged by the wiper arm adapter unit (10a-10e) as the wiper arm adapter unit (10a-10e) is moved toward the wiper blade adapter unit (12a-12c) along the longitudinal direction (16a-16e), such that the barb (30a-30d) is pressed and moved along a transverse direction (46a-46e) that is perpendicular to the longitudinal direction (16a-e) and also perpendicular to a vertical direction (44a-44e), the vertical direction (44a-44e) being perpendicular to a wiping plane, and such that the barb is moved away from a naturally biased position by the movement of the wiper arm adapter unit (10a-10e) along the longitudinal direction (16a-16e), and such that the barb (30a-30d) returns toward the naturally biased position to inhibit the wiper blade adapter unit (12a-12c) from disengaging from the wiper arm adapter unit (10a-10e) when the wiper blade adapter unit (12a-12c) and the wiper arm adapter unit (10a-10e) are in the installed state, wherein the wiper blade adapter unit (12a-12c) includes a base body (22a-22e), wherein the base body (22a-22e) includes a lateral wall (32a-32e) defining three sides of a rectangular recess (28a-28e) along a bottom of the lateral wall (32a-32e) of the base body (22a-22e), wherein the lateral wall of the wiper arm adapter unit (10a-10e) includes a lower portion that, longitudinally between two of the sides thereof, extends into the recess (28a-28e) in the installed state, such that the lower portion of the lateral wall of the wiper arm adapter unit (10a-10e) prevents movement of the wiper arm adapter unit (10a-10e) along the vertical direction (44a, 44d, 44e), and wherein in the installed state the lateral wall (32a-32e) of the base body (22a-22e) further prevents the lower portion of the lateral wall of the wiper arm adapter unit (10a-10e) from moving in the longitudinal direction (16a-16e).

### Claim 2 (depends on 1)

The wiper device according to claim 1, wherein the detent means (18a-18e) is integrally formed with the base body (22a-22e) of the wiper blade adapter unit (12a-12e).

### Claim 3 (depends on 1)

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).

### Claim 4 (depends on 1)

The wiper device according to claim 1, wherein the barb engages behind a back stop of the wiper arm adapter (10) in the installed state.

### Claim 5 (depends on 1)

The wiper device according to claim 1, wherein the barb includes a wedge-shaped tip.

### Claim 6 (depends on 1)

The wiper device according to claim 1, wherein the wiper arm adapter unit (10a-10e) is coupled to a wiper arm (26a-26e), and wherein the barb protrudes away from the base body (20a-22e) along the longitudinal direction (16a-16e) toward the wiper arm (26a-26e).
