Abstract

An attachment for a wiper arm of a windscreen wiper of a vehicle, having a rod arm, comprises a fluid channel for conducting a fluid and a first dimensionally stable element, wherein a first fluid channel section is formed in the first dimensionally stable element. The attachment also comprises a second dimensionally stable element, wherein a second fluid channel section is formed in the second dimensionally stable element. A wiper arm including the attachment is also disclosed.

First claim

What is claimed is:

1. An attachment for a wiper arm, having a rod arm, of a windscreen wiper of a vehicle, wherein the attachment comprises:
a fluid channel for conducting a fluid,
a first dimensionally-stable element, wherein a first fluid channel section is formed in the first dimensionally-stable element, and
a second dimensionally-stable element, wherein a second fluid channel section is formed in the second dimensionally-stable element,
wherein
the first dimensionally-stable element has a connecting section for connecting the first dimensionally-stable element to the rod arm, wherein the connecting section of the first dimensionally-stable element has a receptacle for accommodating the rod arm, and the receptacle of the first dimensionally-stable element defines an opening through which the rod arm can be inserted into the receptacle of the first dimensionally-stable element,
and/or
the second dimensionally-stable element has a connecting section for connecting the second dimensionally-stable element to the rod arm, wherein the connecting section of the second dimensionally-stable element has a receptacle for accommodating the rod arm, and the receptacle of the second dimensionally-stable element defines an opening through which the rod arm can be inserted into the receptacle of the second dimensionally-stable element,
and
a flexible element is provided which has a connecting section for connecting the first dimensionally-stable element to the rod arm, wherein the connecting section of the flexible element has a receptacle for accommodating the rod arm, and the receptacle of the flexible element defines an opening through which the rod arm can be inserted into the receptacle of the flexible element,
wherein the flexible element covers the first dimensionally-stable element at least in sections, and the flexible element covers the second dimensionally-stable element at least in sections.

2. The attachment according to claim 1 , wherein a third fluid channel section is formed in the flexible element.

3. The attachment according to claim 1 , further comprising a carrier with a connecting section for connecting the carrier to the rod arm, wherein the first dimensionally-stable element and the second dimensionally-stable element are arranged on the carrier in such a way that a section of the connecting section of the carrier forms the connecting section of the first dimensionally-stable element, and another section of the connecting section of the carrier forms the connecting section of the second dimensionally-stable element.

4. The attachment according to claim 1 , wherein a connector for a hose and/or a nozzle carrier and/or a wiper blade and/or a fastener is formed on the first dimensionally-stable element, and/or a connector for a hose is formed on the second dimensionally-stable element.

5. The attachment according to claim 1 , wherein the first dimensionally-stable element and/or the second dimensionally-stable element has a fluid outlet or a nozzle element.

6. The attachment according to claim 1 , wherein the flexible element has a protruding wind deflector.

7. The attachment according to claim 1 , wherein the flexible element has a base body and an end section, and wherein a bending section is provided between the base body and the end section.

8. The attachment according to claim 1 , further comprising a lateral fluid outlet through which a portion of the fluid guided through the fluid channel can be discharged.

9. A wiper arm of a windscreen wiper of a vehicle with a rod arm, comprising an attachment according to claim 1 , wherein
the first dimensionally-stable element is connected to the rod arm via the connecting section of the first dimensionally-stable element, wherein the rod arm is accommodated in the receptacle of the connecting section of the first dimensionally-stable element,
and/or
the second dimensionally-stable element is connected to the rod arm via the connecting section of the second dimensionally-stable element, wherein the rod arm is accommodated in the receptacle of the connecting section of the second dimensionally-stable element,
and
the flexible element is connected to the rod arm via the connecting section of the flexible element, wherein the rod arm is accommodated in the receptacle of the connecting section of the flexible element,
wherein the flexible element covers the first dimensionally-stable element at least in sections, and the flexible element covers the second dimensionally-stable element at least in sections.

10. The wiper arm according to claim 9 , wherein the attachment is connected to the rod arm in such a way that a displacement of the attachment with respect to the rod arm in the longitudinal direction of the rod arm is prevented.

11. The wiper arm according to claim 9 , wherein the flexible element partially covers the rod arm and the carrier.

12. The wiper arm according to claim 9 , further comprising a nozzle carrier with a nozzle and a wiper blade adapter, which nozzle is in fluid connection with the fluid channel of the attachment.

13. A windscreen wiper of a vehicle with a wiper arm according to claim 9 and a wiper blade.

14. A method for mounting a fluid channel for conducting a fluid on a rod arm of a wiper arm of a windscreen wiper, comprising fastening the attachment according to claim 1 and the rod arm.

15. A system comprising a first attachment and a second attachment, the first and second attachments each being the attachment of claim 1 , and further comprising coupling means via which the first attachment is connected to the second attachment.
