The recess is preferably configured to be "at least substantially cutout-shaped" to mean that the cutout-shaped recess can have an at least partially arcuate or curved course in at least one direction.

[0016] An advantageously small movability of the coupling element of the fluid, in particular in the bearing plane along the longitudinal axis of the covering unit, can be achieved with a greater movability perpendicular to the longitudinal axis.

[0017] It is further proposed that the at least one bearing recess is at least substantially configured in the shape of a cutout.

The at least one bearing recess is preferably configured curved along a circular arc around the pivot axis. "The at least one bearing recess is at least substantially configured concavely as viewed from the pivot axis" preferably means that the bearing recess is at least predominantly configured arched, wherein the bearing recess is at least predominantly configured curved towards the direction of the pivot axis. The bearing recess can in particular be configured curved along a circular arc around the pivot axis. An advantageous simple connection of the fluidic coupling element to the fluidic connection element when the covering element is pivoted can be achieved.

[0019] It is further proposed that the at least one fluidic coupling element has at least one alignment rib at the side facing away from the wiper blade adapter for aligning the at least one fluidic coupling element for connecting the at least one fluidic coupling element to the fluidic connection element.
