Embodiment Construction

[0037] figure 1 is a schematic diagram showing a motor vehicle windshield 1 to be wiped by the wiping device 2 . The wiping device 2 comprises a first arm 3 and a second arm 4 each connected by a drive to eg an axis of rotation 5 . The two arms are displaced on the windshield 1 by a combined reciprocating movement or an opposite reciprocating movement.

[0038] The wiper brush 6 is located at the opposite end of the axis 5 with respect to the first arm 3 and the second arm 4 and its function is to scrape the windshield to push water lying thereon back to an area of ​​the windshield where it does not obstruct visibility . These wiping brushes 6 are connected to the arms by means of connectors which allow the wiping brushes to be replaced after they have worn out.

[0039] For example, each wiping brush comprises two supplies for spraying liquid, in particular windscreen washer fluid. These feeds extend longitudinally along the same axis as the longitudinal axis of the wipin...

Abstract

The invention relates to an electrical and hydraulic coupling device 10 for a system for supplying and / or distributing liquid to be sprayed onto a window of a vehicle, comprising at least one tube 22 and at least one first electrically conductive cable 21, 34, the tube 22 is delimited by a wall 25 in which are formed at least two liquid circulation ducts 23, 24 and in which is embedded a heating element 26, said wall comprising at least one recess 37 open towards the outside of the tube 22 and in which is housed all or part of said cable 21, 34. The invention also relates to the applications in motor vehicles.

Description

technical field [0001] The technical field of the invention relates to supply and / or distribution systems for windscreen washer fluid in motor vehicles. Such systems accompany vehicle window wiping devices. More precisely, the present invention aims at the device for transferring and heating the liquid, or what is called the electrical and hydraulic coupling of the liquid transferred between the tank and the spraying system. Background technique [0002] Vehicles are routinely equipped with wiping equipment and washing systems to ensure that the windshield is wiped and washed, thus preventing the driver's view of the environment from being disturbed. These wiping devices consist of an arm performing an angled reciprocating movement, the end of which is fitted with an elongated brush carrying a blade made of elastic material. These blades rub against the windshield and repel water by drawing it out of the driver's field of vision. The brush is attached to the swivel arm of...
