Problems solved by technology

Thus, the operation proved to be very dangerous due to the potential risks it could cause
Furthermore, depending on the speed of the vehicle, the sprayed jet is variable, for example, at higher speeds, the jet is sprayed only on the lower part of the window surface, which naturally results in insufficient cleaning of said vehicle surface
Furthermore, it can be understood that the flushing system thus needs to be designed specifically for each vehicle, which leads to a substantial increase in research and development costs

Embodiment Construction

[0030] figure 1 A perspective view showing a wiping and washing assembly for wiping and washing a vehicle window surface, including a pair of windscreen wiper blades according to the invention in an unactuated position. In this figure, the windscreen wiper blade 1 is mounted on the arm 2 in a conventional manner by means of an articulation arranged substantially in the central part of the windscreen wiper blade 1 . The other end of the arm 2 is fixed to a motor arrangement coupled to the vehicle body 3 for synchronously passing the wiper blade over the area 4a-4b on the window surface to be wiped, for example the windshield 5 . In the figures, the windscreen wiper blades 1 are shown in an unactuated position, ie in a position parallel to each other and substantially parallel to the lower edge of the windscreen. The windshield wiper blades as shown are so-called counter pieces because they move relative to each other. The windscreen wiper blades may also move parallel to each...

Abstract

The invention relates to a windshield wiper blade of a motor vehicle, comprising an elongate flexible strip, wherein at least one end of the strip is covered by a cap with a built-in conduit provided with a nozzle offset on the side of the flexible strip relative to the longitudinal median plane of said flexible strip.

Description

technical field [0001] The invention relates to a windscreen wiper blade, the essential feature of which is that it comprises at one of its ends at least a duct equipped with a nozzle integrated in the cap of the windscreen wiper blade . Background technique [0002] In the prior art, cleaning of the windshield or the rear window of the vehicle is traditionally carried out by spraying a washer fluid on the window surface by means of nozzles arranged on the vehicle body or on the vehicle's flashing grille. The nozzles, which are located at a distance from the window surface to be cleaned, are very sensitive to the adjustment to obtain the spray effect. These jet nozzles spray the washer fluid as a spray over most of the window surface. This flushing operation uses large amounts of fluid and can obscure the driver's view within seconds. Thus, this operation proves to be very dangerous due to the potential risks it may entail. Furthermore, depending on the speed of the vehi...
