    [0001] BACKGROUND OF THE INVENTION The present invention relates to a wiper blade, a wiper system and a wiping method of a wiper blade, system and method for wiping a motor vehicle glazed surface. a glass surface of a motor vehicle. Automobiles are commonly equipped with wiping facilities and washing systems to wipe and wash the windshield and to prevent the driver's vision from being disturbed. Such an installation generally comprises two wiper blades which scrape the outer surface of the windshield so as to evacuate the water present on this surface. The washing system includes one or more nozzles, arranged in the hood or arms of the wipers, for projecting a washing liquid on the windshield. Vehicles are also increasingly equipped with sensors that analyze the state of the windshield or the condition of the road. It can be a rain sensor or a sensor of sunshine, fog, dirt or a sensor panels. These sensors may include a camera or one or more cameras. These sensors assist the driver in driving, for example by alerting the driver in case of danger or participating in the automatic activation of a vehicle function (automatic brake release warning, automatic triggering of windscreen wipers in the case of viewing of water drops on the windshield, control of certain functions of the projectors, etc ...) or simply improve the visibility of the driver. Such sensors are generally installed at an upper portion of the windshield. Their proper functioning is conditioned by the state of cleanliness of this area of the windshield. It is therefore necessary to carry out an efficient and regular cleaning of this area. A disadvantage is that the hood nozzle of the washing system is disposed far from the upper part of the windshield. In fact, the nozzle may not project enough washer fluid into the area of the windshield behind which the sensor is installed. Similarly, when the nozzles are arranged on the windscreen wiper arms, these may also not be entirely satisfactory in particular VVFR2160 2 at high speed, because the air flow tends to cause the windshield washer fluid to - above the flag, thus preventing it from reaching the upper area of the windshield. From this it follows that the cleaning of the area of the windscreen behind which the sensor is placed may not be sufficiently efficient, which may lead to sensor detection errors which may cause warnings or misunderstandings. malfunction. The present invention proposes to remedy at least partially the disadvantages mentioned above by presenting a wiper blade, a wiper system and a method of wiping a vehicle window allowing the particular cleaning of a vehicle. windshield area behind which is a sensor. To this end, the subject of the invention is a wiper blade for a wiper system for a glazed surface of a motor vehicle, designed to be pivotally driven by an actuating arm of a wiper system. , characterized in that it comprises at least one dedicated watering orifice configured to project washing fluid on a predetermined area of the glass surface behind which a sensor is arranged, said dedicated watering orifice being arranged at a portion of the wiper blade sweeping said predetermined area of the glass surface, and forming a greater sprinkler density at said portion of the wiper blade than at the rest wiper blade and / or having a larger opening section than the watering holes located outside the predetermined area. The predetermined area of the glass surface behind which the sensor is arranged can thus be cleaned effectively by the washing fluid projected by the (or) orifice (s) dedicated irrigation (s). This allows the motor vehicle devices using the data from the sensor, such as advanced driver assistance systems software using the images from cameras, to function properly. It is further ensured that said predetermined area is wiped after being watered. According to one or more characteristics of the wiper blade, taken alone or in combination: the at least one dedicated watering orifice is configured to project a washing fluid on said predetermined zone upstream and / or downstream of the broom; wiper blade when the wiper blade is pivoted, - the wiper blade is devoid of watering orifices outside the at least one dedicated watering orifice arranged in said portion of the wiper blade; wiper blade. The washing fluid is then projected onto a VVFR2160 portion of the windshield alone, which saves the washing fluid. This reduces the size of the tank and therefore the weight of the vehicle. the windscreen wiper blade comprises at least one watering boom comprising a plurality of watering orifices extending along the longitudinal axis of the windscreen wiper blade, the watering orifice; Dedicated being aligned with the spray boom in said portion of the wiper blade sweeping said predetermined area. A larger amount of washing fluid is thus projected onto the predetermined area than on the remainder of the glass surface during a scanning cycle. the at least one dedicated watering orifice arranged in said portion of the wiper blade sweeping said predetermined zone is situated on the opposite side of the side of the wiper blade on which is provided at least one orifice of watering for projecting washing fluid on the glass surface. With separate washing fluid channels to supply, on the one hand, the dedicated watering orifice (s) and, on the other hand, the watering orifices of the glass surface, it is possible to limit the amount of wash fluid projected for cleaning the predetermined area. The invention also relates to a wiper system for a motor vehicle glazed surface, comprising at least one actuating arm intended to drive a wiper blade pivoting, a glass surface and a sensor, characterized in that said actuating arm comprises at least one dedicated watering orifice configured to project a washing fluid onto a predetermined area of the glass surface behind which the sensor is arranged, the at least one orifice of Dedicated watering being oriented so that the proximal portion of the jet of sprayed wash fluid deviates from the longitudinal axis of the wiper blade at an angle greater than 2 °, preferably 3 °. The particular orientation of the dedicated watering orifice thus makes it possible to maximize the quantity of fluid projected onto said predetermined zone, by targeting said zone when the actuating arm carrying the dedicated watering orifice pivots as close to said area. According to one or more characteristics of the wiper system taken alone or in combination, the wiper system comprises a device for controlling the washing fluid configured to project washing fluid through the at least one dedicated watering orifice according to the direction of rotation or the angular position of the wiper blade or the actuating arm. It saves WFR216O 4 and the washing fluid, which reduces the size of the tank and therefore the weight of the vehicle. the wiper system comprises a device for controlling the pivoting of the windscreen wiper blades configured to control at least one additional back and forth scan of the predetermined area during a round-trip scanning cycle of the glass surface . This additional round-trip scanning of the predetermined zone makes it possible to increase the amount of washing fluid projected onto the predetermined zone of the glass surface and its wiping with respect to the remainder of the glass surface.
    [0002] The invention further relates to a wiper system for a motor vehicle glazed surface, comprising at least one actuating arm, a glazed surface and a sensor, characterized in that it comprises a wiper blade. ice as described above, driven in pivoting by the actuating arm. According to one or more characteristics of the wiper system taken alone or in combination, the wiper system comprises a device for controlling the washing fluid configured to project washing fluid through the at least one dedicated watering orifice according to the direction of rotation or the angular position of the wiper blade or the actuating arm. The wiper system comprises a device for controlling the pivoting of the windscreen wiper blades configured to control at least one additional round-trip scanning of the predetermined zone during a round-trip scanning cycle of the glass surface; . The subject of the invention is also a method of wiping a glazed surface of a motor vehicle with a wiper blade, characterized in that at least one dedicated watering orifice is sprayed with a washing fluid on a predetermined area of the glass surface at the rear of which a sensor is arranged from a wiper system as described above. According to one or more characteristics of the wiping process taken alone or in combination, the washing fluid is sprayed by the at least one dedicated watering orifice only during a portion of the round-robbing cycle of the surface. glazed, - the washing fluid is projected by the at least one dedicated watering orifice, only when the wiper blades sweep the predetermined area, VVFR2160 5 - the washing fluid is projected by the at least one orifice d dedicated watering only during the ascending or descending phases of the scanning, - a round-trip scanning cycle of the glazed surface comprises at least one additional round-trip scanning of the predetermined zone, - during the round-trip scanning cycle of the glass surface, the washing fluid is projected by the at least one dedicated watering orifice only on one side of the windscreen wiper blade and only on the opposite side in the downward phase, the at least one dedicated watering orifice being arranged on the opposite side.

In these figures, identical elements bear the same reference numbers. Figure 1 shows a wiper system 1 of a glazed surface 2 of a motor vehicle, such as the windshield. The wiper system 1 comprises at least one actuating arm 3 for driving a respective windscreen wiper blade 4 to scrape the outer surface of the glass surface 2 in a succession of round-trip scan cycles. . According to a first example shown in FIG. 1, the wiper blade 4 comprises one or more irrigation orifices 5 (or nozzle) configured to project a washing fluid 9 onto the glass surface 2. The 4 includes for example one or two spray bars respectively comprising a plurality of watering orifices 5 extending along the longitudinal axis L of the windscreen wiper blade 4. The watering orifices 5 are hydraulically connected to a washing fluid pump 6 of the motor vehicle, itself connected to a reservoir 7. The wiper blade 4 further comprises at least one dedicated watering orifice 8 configured to project fluid 9 on the outer face of the glass surface 2, on a predetermined area of the glass surface 2 at the rear of which a sensor 10 is arranged. The predetermined zone Z is for example an upper part of the glass surface 2 of the windscreen, on the driver's side. The sensor 10 is arranged behind the glass surface 2, on the inside of the vehicle. It makes it possible to determine the state of the windshield or the state of the road at the front through the glazed surface 2. It can thus be a rain detector or a sunshine sensor, of fog, dirt or a sensor of signs. The sensor 10 comprises for example an optical sensor such as a camera or a camera whose lens is oriented towards the front of the vehicle.
    [0004] VVFR2160 7 The sensor 10, for example, assists driving assistance, for example by alerting the driver in the event of danger or by participating in the automatic activation of a vehicle function (automatic brake release warning, automatic triggering of the wipers). ice cream in the case of viewing water drops on the windshield, controlling certain functions of the projectors, etc ...) or simply improving the visibility of the driver. The dedicated watering orifice 8 is arranged at a portion of the windscreen wiper blade P scanning the predetermined zone Z. By a dedicated watering orifice 8 is meant an orifice which increases the density of the orifices of watering at the portion of the wiper blade P sweeping the predetermined zone Z or an orifice having an opening section widened relative to the watering orifices 5 located outside the portion of the wiper blade; For example, if the spacing of the orifices outside the portion P is constant per unit length, a dedicated watering orifice 8 increases, at least locally at the portion of the wiper blade. ice P, the number of orifices per unit length. In another example, if no other watering orifice 5 is formed in the brush outside the portion P, at least one dedicated watering orifice 8 formed in the portion P increases, at least locally at the level of the portion of the water. wiper blade P, the density of the orifices. The wiper blade 4 may thus comprise one or more orifice (s) of watering 5, 8 in the portion of the windshield wiper blade P and none, one or more orifice (s) of watering 5 on the remainder of the wiper blade 4. The density of irrigation orifices 5, 8 is thus greater than on the rest of the wiper blade 4.
    [0005] Or, the wiper blade 4 may comprise at least one dedicated watering orifice 8 arranged in the portion of the wiper blade P sweeping the predetermined zone Z, having an opening section larger than that 5. Thus, if the number of watering holes per unit length is for example constant over the length of the wiper blade 4, at least one of the orifices of the portion of the wiper blade windscreen wiper P sweeping the predetermined zone Z has, with respect to the watering orifices 5 outside the portion P, a widened diameter. The predetermined zone Z of the glass surface 2 behind which the sensor 10 is arranged can thus be effectively cleaned by the washing fluid 9 projected by the dedicated irrigation orifice (s). of the motor vehicle using the data from the sensor 10, such as the advanced systems software VVFR2160 8 driver assistance using images from cameras, to work properly. It is further ensured that the predetermined zone Z is wiped after being watered. In the first embodiment shown in Figures 1 to 6, the dedicated watering orifice 8 is aligned with the watering orifices 5 of the irrigation boom. When the wiper blade 4 is pivotally driven, the washing fluid 9 is thus projected by the dedicated watering orifice 8 on the predetermined zone Z upstream and / or downstream of the windscreen wiper blade. 4. For example, the washing fluid 9 is projected in the same way by the watering orifices 5 and the dedicated watering orifice 8, in the rising phase and in the downward phase of the sweeping. Thus, during the scanning, the washing fluid 9 is more specifically projected on a predetermined zone Z of the glass surface 2 behind which the sensor 10 is arranged. Figures 7 to 10, successive at the end of the rising phase of the scan illustrated in Figure 6, show a first embodiment of the wiping process. In this variant, the wiper system 1 comprises a device for controlling the pivoting of the wiper blades 11, configured to control the motor 12 of the actuating arms 3 to perform at least one additional round-trip scanning of the wiper blade 11. predetermined zone Z during the round-trip scan cycle. This additional return sweep of the predetermined zone Z makes it possible to increase the amount of washing fluid 9 projected on the predetermined zone Z of the glazed surface 2 and its wiping with respect to the remainder of the glazed surface 2. To reduce the consumption of washing fluid 9, it can be provided that the wiper system 1 comprises a device for controlling the washing fluid 13, configured to control the release of the washing fluid pump 6 so as to project washing fluid 9 through the dedicated watering orifice 8 according to the pivoting direction or the angular position of the wiper blade 4 or the actuating arm 3. The washing fluid 9 specifically projected on the predetermined zone Z can thus be projected only during a portion of a round-trip scanning cycle of the glass surface 2. For example, it is expected that the washing fluid 9 is only projected by the dedicated watering orifice 8 during rising phases of the scan (Figures 9 and 10). The washing fluid 9 is not projected by the dedicated watering orifice 8 during the downward phases of the sweeping (FIGS. 7 and 8). This saves the fluid VVFR2160 9 washing, which reduces the size of the tank 7 and therefore the weight of the vehicle. Conversely, it can be provided that the washing fluid 9 is only projected by the dedicated watering orifice 8 during the downward phases of the sweep.
    [0006] According to another example illustrated in FIGS. 11 and 12, which represent two successive positions of the wiper blade 4 in the descending phase of the scanning, the washing fluid 9 is projected by the dedicated watering orifice 8 only when the The wiper blades 4 scan the predetermined zone Z, that is to say when they pass over the area of the glass surface 2 behind which the sensor 10 is arranged (FIG. 12).
    [0007] The washing fluid 9 is not projected by the dedicated watering orifice 8 when the windscreen wiper blade is located outside the predetermined zone Z (FIG. 11). According to another variant embodiment illustrated in FIGS. 13 to 16, the dedicated watering orifice 8 is arranged in the portion of the wiper blade P sweeping the predetermined zone Z, on the opposite side of the side of the wiper blade. windscreen wiper 4 on which is provided at least one watering orifice 5 for spraying washing fluid 9 on the glass surface 2. The dedicated watering orifice 8 is hydraulically connected to the washing fluid pump 6 for example by lines independent of those supplying the or orifices of irrigation 5 of the glass surface 2 in washing fluid. The dedicated watering orifice 8 and the watering orifices 5 of the glass surface 2 are thus arranged to project the washing fluid respectively on either side of the longitudinal axis L of the wiper blade 4. The density of irrigation orifices 5, 8 is then greater in the portion P of the wiper blade 4 scanning the predetermined zone Z than on the rest of the wiper blade 4. Thus, during of the sweeping, the washing fluid 9 can be projected only on the front side of the windscreen wiper blade 4 (FIGS. 14, 15, 16). Then in a down phase, the washing fluid 9 is only projected on the front side of the wiper blade 4 by the dedicated watering orifice 8, that is to say on the opposite side, specifically on the predetermined zone Z (FIG. 13). The dissymmetry between the watering orifice 5 (or spray bar) on one side of the brush 4 and the dedicated watering orifice 8 on the other side, allow a greater amount of washing fluid 9 is projected on the predetermined zone Z than on the rest of the glass surface 2 during a round-trip scanning cycle of the glazed surface 2. In addition, the consumption of washing fluid 9 is limited.
    [0008] VVFR2160 10 According to another embodiment of the brush shown in Figure 17, the wiper blade 41 has no other watering orifices that those of the dedicated watering orifice 8, arranged in the portion of Wiper blade P intended to scan the predetermined zone Z. It is thus devoid of watering orifices outside the dedicated watering orifice 8 arranged in the portion of the blade P. The washing fluid 9 is then only projected on a portion of the windshield, which saves the washing fluid 9. This reduces the tank dimensions and therefore the weight of the vehicle. Instead of being arranged in the windscreen wiper 4, the dedicated watering orifice 81, configured to project a washing fluid on the predetermined zone Z, can be arranged in the actuating arm 31. Dedicated irrigation orifice 81 is for example directly integrated with the actuating arm 31, for example being formed in the body of the actuating arm 31 or may be arranged in a separate element separate from the arm, the element being attached to the body of the actuating arm 31.
    [0009] In this case and as shown in FIGS. 18 and 19, the at least one dedicated watering orifice 81 is oriented so that the proximal portion Pp at the wiper blade 4 of the projected washing fluid jet 9 deviates the longitudinal axis L of the wiper blade 4 at an angle y greater than 2 °, preferably 3 °. In addition, it is expected that the jet of washing fluid 9 fits for example in a cone at the apex angle p of the order of 42 ° maximum. In use, the dedicated irrigation orifice 81 projects a washing fluid 9 upstream and / or downstream of the wiper blade 41. The particular orientation of the dedicated irrigation orifice 81 thus makes it possible to maximize the amount of washing fluid 9 projected on the predetermined zone Z, targeting the zone Z when the actuating arm 31 carrying the dedicated watering orifice 81, pivots closer to the zone Z.
