A wiper device for cleaning a vehicle window, comprising
- a wiper arm fastened in a torque-proof manner to a wiper shaft via an articulation piece, wherein the wiper arm is arranged pivotably on the articulation piece in a pivot axis;
- a wiper blade arranged on the wiper arm;
- and
- a washing device for the wiper blade, which contains a feed for a washing fluid, wherein the feed runs in the longitudinal axis of the wiper shaft and leads to the wiper blade in a direction running substantially perpendicularly to the longitudinal axis, wherein
- the feed comprises an outlet connecting piece arranged on the articulation piece or on the wiper arm, oriented parallel to the longitudinal axis of the wiper shaft,
- the outlet connecting piece in the operating position of the wiper blade engages in a mount constructed on the wiper arm or on the articulation piece, and
- the wiper arm is pivotably arranged in the articulation piece perpendicularly to the longitudinal axis of the wiper shaft at least between two positions, a first position, in which the outlet connecting piece engages into the mount, and a second position, in which the outlet connecting piece is out of engagement with the mount.
A wiper arm comprising:
- a wiper arm carrier element,
- wherein the wiper arm is fastened in a torque-proof manner to a wiper shaft via an articulation piece, the wiper arm being arranged pivotably on the articulation piece in a pivot axis,
- wherein a wiper blade is arranged on the wiper arm,
- wherein a washing device for the wiper blade contains a feed for a washing fluid,
- wherein the feed runs in the longitudinal axis of the wiper shaft and leads to the wiper blade in a direction running substantially perpendicularly to the longitudinal axis
- wherein the feed comprises an outlet connecting piece arranged on the articulation piece or on the wiper arm, oriented parallel to the longitudinal axis of the wiper shaft,
- wherein the outlet connecting piece in the operating position of the wiper blade engages in a mount constructed on the wiper arm or on the articulation piece, and
- wherein the wiper arm is pivotably arranged in the articulation piece perpendicularly to the longitudinal axis of the wiper shaft at least between two positions, a first position, in which the outlet connecting piece engages into the mount, and a second position, in which the outlet connecting piece is out of engagement with the mount.
