    DESCRIPTION
    WINDSHIELD BRUSH.
    Object of the invention.
    The invention relates to a windshield wiper blade, applicable in motor vehicles and having features aimed at improving windshield cleaning.
    State of the art.
    Currently there are a variety of wiper blades for motor vehicles, which have a wide range of construction forms.
    The current wiper blades do not give an efficient solution to the cleaning of those substances that are embedded in the windshield after long hours of driving. Normally, even if the windshield wiper system is operated with cleaning water supply, it is customary to make the windshield even more dirty. This occurs because current brush designs do not descale many of the particles that can fall on the windshield.
    All manufacturers seek to maximize the efficiency of the brushes by designing new profiles and construction forms to increase the pressure on the windshield at the time of operation.
    To solve these inconveniences, the applicant of the present invention developed a windshield wiper device, described in the Spanish patent application 201431045. Said windshield wiper device comprises: a brush designed to contact and sweep over a windshield of a vehicle to remove water and water. dirt, and a support structure supporting the brush and attachable to a drive arm of the windshield wiper device;

    presenting the particularity that the brush comprises: two scraper lips arranged parallel along the brush, and a scraper brush arranged along the brush between the two scraper lips; defining the two scraper lips and the scraper brush three different areas of contact of the brush with a windshield of a vehicle.
    The disposition of the scraper brush between the two scraper lips guarantees the removal, by the scraper lips, of the substances descaled by the brush, regardless of the direction of rotation of the windshield wiper. In this way it is achieved that in each sweep of the windshield wiper it is disintegrated and any substance adhered to the windshield is removed.
    Therefore, this background has adequate characteristics to effectively remove dirt adhered to the windshield, by brush action.
    However, when it rains and the windshield wiper is being used continuously, the permanent and joint actuation of the lips and the brush on the windshield is not necessary, since under these conditions the scraper lips together with the rainwater perform a proper cleaning of the windshield wiper.
    Therefore, in these conditions, there is a drawback that there is an unnecessary operation and wear of the brush, with the consequent reduction in its useful life.
    Description of the invention
    The windshield wiper device object of this invention, being of the type mentioned above, has constructive particulars oriented to provide two possible modes of operation of the device, selectable at the user's convenience depending on the type of cleaning to be performed.
    In a first mode of operation, which is the default mode, the brush is arranged in an inoperative position, delayed with respect to the plane of

    contact of the scraper lips with the windshield wiper; said scraper lips being responsible for removing rainwater and dirt from the windshield.
    In a second mode of operation, selectable by the user, the brush is arranged in a more advanced operating position, acting simultaneously with the scraping lips on the surface of the windshield, to perform a more intense cleaning of the windshield.
    Since this cleaning is usually selected by the driver of the vehicle when there is more persistent dirt adhered to the windshield, a solution has been devised that the displacement of the scraper brush from the
    inoperative position until the operative position occurs automatically
    when the driver activates the cleaning water supply system to the
    wiper washer.
    In this way, when the windshield wiper is activated, it will work in the first mode of operation, keeping the brush in an inoperative position and acting only the scraping lips on the windshield.
    When the user activates the cleaning water supply system to the
    windshield wiper, the pressure of the cleaning water itself hydraulically drives the scraper brush, causing it to move towards an operative position in which said scraper brush also acts on the windshield wiper, performing a more energetic cleaning thereof during the time that the water supply lasts cleaning.
    For this, this device comprises a supply line, of cleaning water to the brush; said conduit being connected by means of connecting pipes with a longitudinal chamber in which a support base of the brush is housed with the possibility of vertical displacement between an inoperative position, in which the bristles of the brush are arranged delayed with respect to the plane of contact of the scraping lips with the windshield wiper and an operational position, more advanced, in which the bristles of the brush contact against the windshield.

    The brush has a series of cleaning water outlet holes along it, once the brush has reached its operational position.
    To be able to move the windshield wiper between the inoperative and operational positions, it is enough that you have a stroke of a few millimeters inside the mentioned chamber. As soon as the chamber has been filled with pressurized cleaning water, the brush makes contact with the windshield and immediately the water exits through the brush through the outlet holes defined therein.
    The calculation of the inflow and outflow of water must be adequate to achieve optimum pressure on the windshield.
    With this invention it is possible not to wear the brush excessively when not using it whenever the windshield wiper is activated and, additionally, the cleaning water is supplied at the same point where the windshield wiper is located at every moment. The cleaning water supply will be activated in the usual way by operating the control to clean the windshield with water in the vehicle.
    Description of the figures.
    To complement the description that is being made and in order to facilitate the understanding of the features of the invention, a set of drawings is attached to the present specification in which, with an illustrative and non-limiting nature, the following has been represented:
    - Figure 1 shows a schematic elevation view of an example of realization of the wiper blade, according to the invention.
    - Figures 2 and 3 show profile details of an anterior area of the brush, in which the lips and the brush scraper of the brush can be observed; the brush having been represented in an inoperative position in figure 2 and in an operating position in figure 3.
    Preferred embodiment of the invention.
    In the exemplary embodiment shown in FIG. 1, an exemplary embodiment of the windshield wiper blade of 5 is shown in this invention provided with a body (1) mounted on a mounting structure (2) on a drive arm (B) .
    This brush comprises a pressure supply line (3) for cleaning water, said cleaning water supply being activated, in a customary manner, 10 by actuating the corresponding control located inside the vehicle.
    As can be seen in figures 2 and 3, the brush comprises two scraper lips (11, 12) and a scraper brush (4) provided with bristles (41) and a base (42) mounted on a chamber (13) of the body (1) with the possibility of displacement between an inoperative position represented in Figure 2, in which the bristles are arranged behind the plane of contact of the scraper lips (11, 12) with the windshield of the vehicle, and a position operation shown in Figure 3, in which the bristles (41) are arranged in an advanced position 20 of contact with the windshield of the vehicle.
    The cleaning water supply line (3) is connected by tubes (31) to the chamber (13) of the body (1); accessed by exit holes (43) defined in the base (42) of the brush (4).
    25
    The sections of the duct (3), the tubes (31) and the orifices (43) of the outlet of the cleaning water through the scraper brush are sized so that the supply of cleaning water automatically displaces the brush (4) from the inoperative position, represented in figure 2, to the operational position represented in figure 3; and the cleaning water exits through the holes (43) of the scraper brush, for as long as the cleaning water supply is activated.
    10 It is also provided that the brush can incorporate into the chamber (13) elastic means (not shown) spring type, strapping or the like for the return of the brush (4) to the inoperative position when the supply of cleaning water ceases.
    Once the nature of the invention has been sufficiently described, as well as an example of preferred realization, it is stated to the appropriate effects that the materials, shape, size and disposition of the described elements may be modified, provided that this does not imply alteration of the essential features of the invention that are claimed below.
