The fluid coupling element 24 is laterally supported, particularly at the cover unit 16, particularly at the cover element 44 of the cover unit 16, and particularly in the bearing recesses 54, 54', in a plane perpendicular to the coupling pivot axis 20, and particularly perpendicular to the pivot axis 46. The bearing recesses 54, 54' particularly restrict the degrees of freedom of the bearing protrusions 52, 52'.

[0035] The cover element 44 is configured to form a windshield geometry that uses driving airflow to press the wiper assembly 10 against the window glass. The cover element 44 has a concave outer surface 76 on the side opposite to the wiper adapter 12.

[0036] The cover unit 16 has at least one fluid blocking element 26. The fluid blocking element 26 is configured to ensure fluid connection between the fluid coupling element 24 and the fluid connection element 22. The fluid blocking element 26 and the cover unit 16 are pivotable relative to the wiper arm adapter 14 about the pivot axis 46. Viewed from away from the wiper adapter 12, the fluid blocking element 26 is covered by the cover element 44. The fluid blocking element 26 is configured to secure the fluid connection between the fluid coupling element 24 and the fluid connection element 22. The fluid blocking element 26 is slidably supported on the cover unit 16, particularly relative to the cover element 44. The fluid blocking element 26 is slidably supported along the longitudinal axis 50 of the cover unit 16. The fluid blocking element 26 is configured to surround the fluid coupling element 24, particularly perpendicular to the longitudinal axis 50 of the cover unit 16, in a sliding position, particularly a connected position. The fluid blocking element 26 engages with the fluid-contacting element 22 in the connected position, particularly when viewed from behind the retainer 32 of the wiper arm adapter 14. Optionally, the fluid blocking element 26 in the connected position can be configured to engage with the wiper blade adapter 12, particularly for securing the connected position to prevent undesirable loosening of the connection.

[0037] The covering unit 16 includes at least one cover fixing element 28.

[0038] The cover fixing element 28 is configured to at least partially secure the at least one cover unit 16 to the at least one wiper arm adapter 14.

[0039] The cover fixing element 28 is configured to fix the at least one cover unit 16 in a pivot position, particularly about a pivot axis 46, relative to the at least one wiper arm adapter 14. The cover fixing element 28 is movably supported at the cover element 44. The cover fixing element 28 is slidably supported at the cover element 44.

[0040] The cover retaining element 28 is hook-shaped. The cover retaining element 28 is configured to surround the retainer 32 of the wiper arm adapter 14. In the connected position, the cover retaining element 28 partially surrounds the retainer 32. In this connected position, the cover retaining element 28 secures the cover unit 16 to prevent pivoting about the pivot axis 46 relative to the wiper arm adapter 14, particularly at the retainer 32.

[0041] The wiper assembly 10 has at least one actuating element 30. The actuating element 30 is configured as a slider element, particularly as a sliding member, and is located at the cover element 44, particularly at least most of it, within the cover element.

[0042] The actuating element 30 comprises two integrally connected components, particularly actuating button components 78 and 78'. Alternatively, the actuating button components 78 and 78' can be separate components. The actuating button components 78 and 78' are arranged at the height of the end of the cover unit 16, respectively, when viewed axially along the maximum longitudinal extension of the actuating element 30. The actuating button components 78 and 78' surround the fluid blocking element 26 and the cover fixing element 28 along the longitudinal axis 50 of the cover unit 16. The actuating button components 78 and 78' respectively form at least one form-locking, particularly material-locking, engagement with either the at least one fluid blocking element 26 or the cover fixing element 28. The actuating button component 78 facing the pivot axis 46 forms a form-locking with the fluid blocking element 26. The fluid blocking element 26 has a contact portion with the actuating button component 78 at its side, particularly along the longitudinal axis 50 of the cover unit 16. The fluid blocking element 26 has a convexly curved side that contacts the control button component 78, particularly along a fluid arc around the coupling pivot axis 20. The control button component 78 has a concavely curved side that contacts the fluid blocking element 26, particularly along a fluid arc around the coupling pivot axis 20. The fluid arc around the coupling pivot axis 20 has a larger radius than the arc around the coupling pivot axis 20. The control button component 78, facing away from the pivot axis 46, is material-locked to the cover retaining element 28. The control element 30, particularly the control button component 78, is integrally connected to the at least one cover retaining element 28.

[0043] The actuating element 30 is configured to allow the at least one fluid blocking element 26 and the at least one cap retaining element 28 to be switched together to a connected position and / or a released position by a particularly translational movement of the actuating element 30 relative to the wiper arm adapter 14. The movement of one of the actuating button components 78, 78', particularly along the longitudinal axis 50 of the cover unit 16, also moves the cap retaining element 28, the fluid blocking element 26, and correspondingly the other actuating button components 78, 78', into a sliding position, particularly into the connected or released position. The released position of the fluid blocking element 26 is a sliding position in which the fluid coupling element 24 and the fluid connection element 22 are not fluidly connected by the fluid blocking element 26. The released position of the cap retaining element 28 is a sliding position in which the cover unit 16 is pivotable about the pivot axis 46.

[0044] The fluid blocking element 26 is at least partially pivotally connected to at least one operating element 30 relative to the at least one wiper arm adapter 14. In the connection position between the fluid blocking element 26 and the wiper blade adapter 12, the fluid blocking element 26 is movable relative to the wiper arm adapter 14, and in particular, pivotal. In the connection position between the fluid blocking element 26 and the wiper blade adapter 12, the fluid blocking element 26 is movable relative to the operating button component 78, and in particular, pivotal. When the fluid blocking element 26 pivots relative to the operating button component 78 in the connection position between the fluid blocking element 26 and the wiper blade adapter 12, the connection is maintained by the shape-locking of the operating button component 78 and the fluid blocking element 26, particularly by the outward curved shape. When the fluid blocking element 26 pivots relative to the control button component 78 about the coupling pivot axis 20 in the connection position between the fluid blocking element 26 and the wiper adapter 12, the connection is maintained by the shape-locking of the cover fixing element 28 and the fluid blocking element 26, particularly by the outward curved shape. The at least one fluid blocking element 26 can be movably, particularly pivotally, relative to the at least one cover fixing element 28 and connected to the at least one wiper adapter 12. The fluid blocking element 26 is movable, particularly pivotal, relative to the cover fixing element 28 about the coupling pivot axis 20 in the connection position between the fluid blocking element 26 and the wiper adapter 12. The control element 30 forms a locking connection with the wiper adapter 12 in the connection position, particularly with the cover fixing element 28 and / or the fluid blocking element 26. The locking element arranged at the control button component 78 forms a locking connection with the cover element 44.

[0045] The movement of the actuating element 30 ensures fluid continuity and protects the cover unit 16 from pivoting around the cover fixing unit at the wiper arm adapter 14. The fluid blocking element 26 follows the movement, particularly the movement, of the cover fixing element 28, especially the actuating element 30, preferably the actuating button components 78, 78', wherein the fluid blocking element 26 is movable relative to the cover fixing element 28, particularly in each sliding position, and particularly pivots. The wiper blade 60 is pivotally connected to the wiper arm adapter 14 and is fluidly supplied.

[0046] The operating element 30 can be operated via the operating buttons 78, 78' at the maximum extended end of the cover element 44 along the longitudinal axis 50 of the cover unit 16. The operating element 30 extends further along the longitudinal axis 50 of the cover unit 16 than the cover element 44. The operating buttons 78, 78' protrude from the cover element 44, particularly along the longitudinal axis 50 of the cover unit 16. The operating buttons 78, 78' are visible from the outside of the cover element 44.

[0047] Figure 5 A method for assembling a wiper assembly 10 is schematically illustrated. In at least one method step, particularly clamping step 82, the at least one electrical male coupling element 56 is pivoted to lock between the pin element 18 and the remainder of the wiper arm adapter 14. In at least one method step, particularly clamping step 82, the at least one electrical male coupling element 56 is clamped into the wiper arm adapter 14 at a position almost perpendicular to the longitudinal axis 68 of the wiper arm adapter 14 (see [link to diagram]). Figure 3 In at least one method step, particularly sliding step 84, the wiper adapter 12 slides onto the pin element 18 via a mechanical connecting element 22, and the electrical female connecting element 58 of the wiper adapter 12 is connected to the electrical male coupling element 56 via a translational sliding motion (see...). Figure 3 and Figure 4 In at least one method step, particularly pivoting step 86, the wiper blade adapter 12 and the electrical male coupling element 56 pivot about the pin element 18, particularly about the coupling pivot axis 20, to the retainer 32. In at least one method step, particularly stopping step 88, the cover element 44 pivots about the pivot axis 46 to the wiper blade adapter 12 and the wiper arm adapter 14. In at least one method step, particularly the stopping step 88, the cover unit 16 is suspended at the retainer 32 by partial pushing of the cover unit 16, particularly the actuating element 30, to prevent pivoting of the cover unit 16.
