The adapter accessory is connected to the adapter base, particularly in the absence of pivotability, mobility, and / or rotatability, especially elastic deflectability. The adapter accessory is preferably configured for a snap-fit connection with the adapter base, particularly a plug connection. The adapter accessory may alternatively or additionally be configured for a joint connection with the adapter base material, such as an adhesive connection and / or a welded connection. At least one adapter accessory may optionally have at least one connecting protrusion for insertion into at least one connecting groove in the adapter base, wherein the connecting protrusion is configured for welding and / or bonding in the connecting groove. The adapter accessory is preferably configured to construct, particularly fully construct, the fluid guiding capability of the wiper adapter.

At least one adapter accessory preferably has no fluid conduit elements such as fluid inlet openings, fluid conduit protrusions, and / or fluid channels in the direction of the adapter base, particularly in the direction parallel to the transverse axis of the adapter accessory. This allows for an advantageous arrangement of at least one adapter accessory outside the adapter base in the surrounding environment of the channel unit.

An advantageously stable, particularly secure, arrangement of the adapter accessory at the adapter base / an advantageously stable, particularly secure, connection between the adapter accessory and the adapter base can be achieved.
[0018] Furthermore, it is recommended that at least two fluid line protrusions be arranged on opposite sides of at least one adapter accessory, transverse to the longitudinal axis of the adapter accessory, in the end region of the largest lateral extension of the adapter accessory, particularly in the end region opposite to the adapter base. The at least two fluid line protrusions are preferably arranged on opposing sides of the adapter accessory, said sides being particularly transverse to the longitudinal axis of the adapter accessory. The term "end region" of the extension of the object preferably refers to an area of the object that includes a maximum of 40%, preferably a maximum of 30%, of the object from one end of the extension. The at least two fluid line protrusions are preferably arranged mirror-symmetrically to each other on opposing sides of the adapter accessory, particularly along the transverse axis of the adapter accessory with reference to a mirror plane passing through the midpoint of the adapter accessory, said sides being particularly transverse to the longitudinal axis of the adapter accessory, particularly in the direction of the fluid lines of the fluid line protrusions. The at least two fluid line protrusions are preferably arranged opposite to the adapter base on opposing sides, said sides being particularly transverse to the longitudinal axis of the adapter accessory. At least two fluid line protrusions are preferably located on the side of at least one adapter accessory that is transverse to the longitudinal axis of the adapter accessory, particularly on the side of the longitudinal axis already mentioned, and particularly in the end region of the largest transverse extension of the adapter accessory opposite to the adapter base, arranged mirror-symmetrically to each other. This allows for an advantageous, space-saving arrangement of the adapter accessories at the adapter base for connection to the channel unit. In particular, it enables the advantageous combination, with the existing windshield design and the channel unit arranged on the outside of the windshield unit, and the wiper adapter design according to the invention, without significant difficulty.
[0019] Furthermore, it is recommended that at least two fluid conduit protrusions each have a fluid conduit direction, which is oriented at an angle of at least 2.5° relative to the longitudinal axis of the adapter accessory. This angle is preferably at least different from 0° or 180°. The at least two fluid conduit protrusions preferably each have a maximum longitudinal extension, which is oriented at an angle of at least 2.5° relative to the longitudinal axis of the adapter accessory. The maximum longitudinal extensions of the at least two fluid conduit protrusions, particularly the fluid conduit direction, are oriented at the same angle relative to the longitudinal axis of the adapter accessory. The maximum longitudinal extensions of the at least two fluid conduit protrusions, particularly the fluid conduit direction, are preferably oriented at the same angle relative to the longitudinal axis of the adapter accessory towards the direction opposite to the adapter base. The maximum longitudinal extensions of the at least two fluid conduit protrusions, particularly the fluid conduit direction, are preferably oriented at the same angle relative to the longitudinal axis of the adapter accessory, at least 3°, preferably at least 4°, and particularly preferably at least 5°.

[0020] Furthermore, it is recommended that at least one adapter accessory has at least one additional fluid conduit protrusion. The fluid conduit direction of the at least one additional fluid conduit protrusion is preferably at least substantially parallel to the longitudinal axis of the adapter accessory, and in particular perpendicular to the side on which the at least one additional fluid conduit protrusion is arranged. "Substantially parallel" here should specifically refer to a direction relative to a reference direction, particularly in a plane, wherein the direction has a deviation relative to the reference direction, particularly less than 8°, advantageously less than 5°, and particularly advantageously less than 2°. The at least one additional fluid conduit protrusion is preferably oriented facing the at least two fluid conduit protrusions. The at least one additional fluid conduit protrusion is preferably arranged on one side of the adapter accessory, on which one of the two fluid conduit protrusions is arranged.

In particular, an advantageously compact fluid area of the wiper adapter within the adapter accessory can be achieved. In particular, the installation time and cost of the wiper adapter, especially the fluid line, at the wiper adapter can be advantageously kept to a minimum, especially by means of the insertion direction of the fluid line. Furthermore, it is recommended that at least one additional fluid line protrusion be arranged in the intermediate region of the largest longitudinal extension of at least one adapter accessory.
