In particular, the at least one receiving element defines at least one receiving chamber. In particular, the at least one receiving element defines the at least one receiving chamber at least substantially parallel to the main extension axis of the wiper arm and / or the base body. "Substantially parallel" in particular means an orientation in particular in one plane with respect to a reference direction, wherein the direction has a deviation with respect to the reference direction of in particular less than 8°, advantageously less than 5° and particularly advantageously less than 2°. It is particularly preferred that the circumference of the at least one receiving chamber in a cross section perpendicular to the main extension axis of the wiper arm is not completely closed.
