With this uncontrolled spraying, there is a risk that oncoming as well as with vehicles driving behind, primarily during periods of bad weather with existing layers of salt and dirt, immediately dirty the panes and any view is taken for seconds, even when used immediately with the conventional spraying devices must be operated in a blind state for too long, so that in these inevitable seconds there is the greatest risk of accident.

The present innovation, on the other hand, has set itself the task with which Spray lance device attached directly to a single-blade windshield wiper, at Use of the same, faster clear washing resp. Wipe effects on the auto yoke to achieve.

The spray tube device can be on one side and on both sides in parallel Single-blade windshield wipers can be attached.

In addition, the spray tube device should be designed and simple mounted on existing vehicles without great effort or difficulty and be replaceable.

The innovation can be installed as a subsequent attachment in the form of accessories will.

The device consists of one or two elastic or Spray tubes made of solid material, which run parallel to the single-blade windshield wiper are attached.

Depending on the type and length of the windshield wiper, this spray lance contains laterally, inclining more towards the pane, or in each case in the middle facing the pane, Holes that make up a liquid in the form of water with or without added detergent is sprayed directly onto the pane.

A special Embodiment several clips on the top of the single-blade windshield wiper attached, in which the spray tube is held in each case. The brackets are designed so that it is attached to the frame of the rubber profile of the single-sheet wiper and can also be dismantled without much ado.

Further details of the innovation are to be found in an exemplary embodiment which is described in more detail below with reference to 3 figures.

Figure 1 shows in a side view the outline of a windshield wiper, which is equipped with the spray tube device according to the invention.

Figure 2 shows in a section corresponding to the section line II-II of Figure 1, the single-blade windshield wiper profile with the bracket bracket of a benz. two spray tubes.
