Description

Wiper arm device with at least one detachable additional nozzle unit Technical Field The present invention relates to a wiper arm apparatus. Background A wiper arm device has been proposed which has at least one channel connection unit for connecting at least two wiper channel sections to one another, at least one channel holding unit which can be arranged on at least one wiper arm and at least one additional nozzle unit, the channel holding unit being provided for holding at least the channel connection unit on the wiper arm. Disclosure of Invention The invention relates to a wiper arm device having at least one channel connection unit for connecting at least two wiper channel sections to one another, at least one channel holding unit which can be arranged on at least one wiper arm and at least one additional nozzle unit, the channel holding unit being provided for holding at least the channel connection unit on the wiper arm. It is proposed that the connection unit is provided for the purpose of connecting the additional nozzle unit, in particular in a non-destructive, releasable manner, to the channel connection unit. The channel connection unit is preferably provided for fluidly connecting at least two wiper channel segments to one another. The channel connection unit in particular delimits at least one further wiping water channel section. The channel connection unit is preferably at least partially constructed as a pipe line connection unit. Preferably, the channel connection unit is configured as a push-fit connection unit, a bayonet connection unit, a crimp connection unit, a flange connection unit, a screw connection unit, a clamping ring screwing unit, an extrusion screwing unit, a moving sleeve connection unit, a plug-in unit, a paste connection unit and/or a sleeve connection unit. Particularly preferably, the channel connection unit has at least two coupling elements and at least two mating coupling elements. At least two coupling elements are preferably arranged on the channel connection unit. Preferably, at least two coupling elements are constructed in one piece with the channel connection unit. "one-piece" is to be understood in particular as being formed as one component.

The at least two mating coupling elements each preferably have a cylindrical inner contour. The wiper arm device has in particular at least one wiper channel unit. The wiper channel unit is preferably provided for guiding the wiper water. Preferably, the wiper channel unit is provided for guiding the wiper water from the wiper water flow container to the at least one nozzle. The wiper channel unit preferably has at least one wiper channel. The wiper channel is preferably embodied as a pipe line and/or a hose line. The at least one wiper channel is preferably formed by at least two wiper channel sections. At least two wiper channel sections are provided for guiding on the wiper arm. Furthermore, at least one of the at least two mating coupling elements on the channel connection unit is preferably arranged on at least one of the at least two wiper channel segments. Preferably, at least one of the at least two mating coupling elements is constructed in one piece with at least one of the at least two wiper channel segments.
