Abstract
Disclosed is an arrangement of nozzle units for a wiper arm, wherein at least one nozzle unit comprises a rigid body, has a channel through which liquid can flow into the nozzle unit and/or out of the nozzle unit, and comprises a nozzle, which is connected to the channel. The nozzle units are in communication with each other in series such that a liquid can flow from a nozzle unit into a following nozzle unit in the series, wherein at least one nozzle unit has a contact surface which is formed such that the nozzle unit cannot rotate about the longitudinal axis thereof if the contact surface contacts a surface of a wiper arm. A wiper arm comprising the arrangement is also disclosed.

An arrangement of nozzle units for a wiper arm, wherein at least one nozzle unit:
- comprises a rigid body;
- defines a channel through which liquid can flow into the nozzle unit and/or out of the nozzle unit;
- and
- comprises a nozzle, which is connected to the channel,
- wherein the nozzle units are in communication with each other in series in the arrangement such that a liquid can flow from a nozzle unit into a following nozzle unit in the series, and at least two nozzle units following each other in the series are directly connected to each other, and
- wherein at least one nozzle unit comprises a contact surface which is formed such that the nozzle unit cannot rotate about a longitudinal axis thereof if the contact surface contacts a surface of the wiper arm.
