Abstract
Description
[0001] The present invention relates to a windscreen wiper for a vehicle. The invention is particularly, but not exclusively, applicable to motor vehicles.
[0002] Those skilled in the art are familiar with a windshield wiper for a vehicle, the windshield wiper comprising:
[0003] a wiper blade configured to wipe a glass surface of the vehicle,
[0004] - a reinforcement member comprising a vertebral support and a vertebra,
[0005] - two connectors fixed to said vertebrae,
[0006] a central mounting, articulated on each of the two connectors and configured to be fastened to a drive arm of a windscreen wiper,
[0007] - An air deflector connected to the vertebral support.
[0008] The windscreen wiper performs the function of wiping a glazed surface of the vehicle, such as a windscreen. The air deflector makes it possible to increase the force with which the windscreen wiper is pressed against the glazed surface of the vehicle. Furthermore, in order to wash the glazed surface with washer fluid, the vehicle comprises a spray nozzle in the hood region, which sprays the washer fluid onto the glazed surface.
[0009] A disadvantage of this prior art is that this type of washing of glazed surfaces is ineffective when the curvature of the glazed surface to be cleaned is very pronounced, or when the glazed surface is panoramic, as in the case of vehicles such as trucks or buses.
[0010] In this context, the present invention aims to propose a windscreen wiper for a vehicle which makes it possible to resolve the above-mentioned drawbacks.

[0090] Unless otherwise stated, elements that are identical in structure or function and appear in the various figures are denoted by the same reference numerals.
[0091] According to a non-limiting example, reference Figures 1 to 34 A windscreen wiper 1 according to the invention for a vehicle 2 is described. In a non-limiting embodiment, the vehicle 2 is a motor vehicle. A motor vehicle is understood to mean any type of motorized vehicle. This embodiment is given as a non-limiting example in the remainder of the description. In the remainder of the description, the vehicle 2 is therefore also referred to as a motor vehicle 2.
[0092] In the following description, the terms "longitudinal" or "lateral" refer to the windscreen wiper 1. The longitudinal direction corresponds to the main axis of the windscreen wiper along which it extends, while the lateral orientation corresponds to straight lines that are conjunct, that is to say, straight lines that intersect the longitudinal direction and, in particular, are perpendicular to the longitudinal axis of the windscreen wiper in the plane in which the windscreen wiper 1 rotates.
[0093] The motor vehicle 2 includes a glazed surface 20 that needs to be scraped and cleaned. In one non-limiting embodiment, the glazed surface 20 is a windshield of the motor vehicle 2.
[0094] [ Figure 1 ] shows an exploded view of a windscreen wiper 1. The windscreen wiper 1 is a flat windscreen wiper, also referred to as a "flat blade".
[0095] The windshield wiper 1 comprises:
[0096] - at least one wiper blade 10,
[0097] a reinforcement member 11 comprising a vertebral support 12.1 and at least one vertebra 12,
[0098] - two connectors 15 fixed to said at least one vertebra 12,
[0099] a central mounting 13 , which is hinged on each of the two connectors 15 ,
[0100] - an air deflector 14, which is connected to the vertebral support 12.1,
[0101] - injection device 16, and
[0102] - Distribution device 17 for the scrubber fluid L.
[0103] like[ Figure 1 ], the windshield wiper 1 is delimited by a lower end 1.1, also called bottom end 1.1, and an upper end 1.2, also called top end 1.2. These two ends form the ends of the wiper blade 10. The ends 1.1 and 1.2 are end parts that make it possible to fix the parts 14 and 12 together and close the two ends of the hydraulic manifold 16a of the injection device 16 (described below).
[0104] The wiper blade 10 is configured to wipe the glass surface 20 of the motor vehicle 2. It is usually made of an elastomer and is retained along its entire length. The windshield wiper 1 is usually fastened to [ Figure 1 ], which is driven by a motor to move back and forth at an angle. The wiper blade 10 is therefore configured to scrape the glazing surface 20 by wiping it during these angled back and forth movements, thereby making it possible to remove the washer fluid L by simultaneously taking it out of the field of vision of the driver of the motor vehicle 2.
[0105] The reinforcing member 11 with the vertebral support 12.1 and the at least one vertebra 12 makes it possible to reinforce the wiper blade 10 so as to facilitate the application of the wiper blade 10 to the embedded glass surface 20. The reinforcing member 11 distributes the bearing force on the drive arm 3 along the wiper blade 10. Therefore, it makes it possible to transmit the pressure of the drive arm 3 by distributing it along the length of the windshield wiper 1. The at least one vertebra 12 is a longitudinal vertebra. It includes a radius of curvature. Therefore, it is not flat. In addition, the vertebra 12 is curved, and its curvature makes it possible to give the wiper blade 10 a curved shape while keeping it pressed against the embedded glass surface 10. In other words, it is the vertebra 12 that generates the curvature of the wiper blade 10. Therefore, the reinforcing member 11 ensures that the wiper blade 10 follows the curved shape of the embedded glass surface 20, such as the windshield of the motor vehicle 2 in the non-limiting example given. In a non-limiting embodiment, the vertebra 12 is metal. This makes it possible to strengthen and bend the wiper blade 10 . The vertebra support 12 . 1 is configured to support the at least one vertebra 12 and the wiper blade 10 .
[0106] In a non-limiting embodiment, the reinforcing member 11 includes two vertebrae 12. Therefore, the vertebra support 12.1 is configured to support the two vertebrae 12. The two vertebrae are placed end to end via their longitudinal ends. In a non-limiting embodiment, the two vertebrae 12 have different radii of curvature from one vertebra 12 to another vertebra, so that different forces can be applied along the wiper blade 10. In a non-limiting embodiment variant, the first vertebra 12 (called the lower vertebra 12) is flatter than the second vertebra 12 (called the upper vertebra 12), which is more curved. The lower vertebra 12 is the vertebra closest to the drive arm 3. In a non-limiting embodiment, the two vertebrae 12 have different lengths. In a non-limiting embodiment variant, the lower vertebra 12 is longer than the upper vertebra 12, and the upper vertebra is shorter. In a non-limiting embodiment, the two vertebrae 12 are aligned in the vertebra support 12.1.
[0107] The central mounting member 13 is configured to be fastened to the drive arm 3. The central mounting member 13 is connected to the end portion 30 ([ Figure 1 ] shown). In one non-limiting embodiment, the drive arm 3 comprises an end portion 30 which is crimped on a rod 31 connected to a housing 32. The end portion 30 thus serves as a connection between the rod 31 and the central mounting 13. In one non-limiting exemplary embodiment, the central pivot is configured to cause a rotation of plus or minus 15° between the windshield wiper 1 and the drive arm. In another non-limiting embodiment, the drive arm 3 comprises an end portion 30 which is integral with the housing 32. In this case there is no rod 31.
[0108] In a non-limiting embodiment, the central mounting 13 is hinged to each of these connectors 15 via a pivot connection. The pivot connection extends perpendicularly to the longitudinal axis of the windscreen wiper 1. In a non-limiting example, the pivot connection is a pin 151 protruding laterally from either side of the connector 15 (for example at [ Figure 1 ]or[ Fig.12 ]) and the opening 131 in the central mounting member 13 configured to receive the pin 151 (e.g., in [ Figure 4 The pivot connection allows the central mounting 13 to rotate relative to the connector 15 in a plane perpendicular to the plane of rotation of the windscreen wiper 1. Having two connectors 15 makes it possible to better distribute the pressure locally on the vertebrae 12.
[0109] In a non-limiting embodiment, the central mounting 13 comprises an air deflection surface 130. This air deflection surface 130 makes it possible to convert the aerodynamic forces generated on the windshield wiper 1 into a downforce which presses said windshield wiper 1 onto the mounting glass surface 20 and will ensure the effectiveness of high-speed wiping and washing. The central mounting 13 is also configured to hold two connectors 15.
[0110] The air deflector 14 is an aerodynamic deflector which uses the relative wind of the motor vehicle 2 to increase the contact force of the wiper blade 10 with the glazed surface 20 to be wiped. Figure 1 ] As shown, in a non-limiting embodiment, the air deflector 14 consists of at least three parts. Thus, it comprises a lower part 14.1 (also called bottom part 14.1), a central part 14.2, and an upper part 14.3 (also called top part 14.3). The lower part 14.1 extends from the lower end 1.1 of the windshield wiper 1 to the first connector 15. The central part 14.2 is located between the two connectors 15. The upper part 14.3 extends from the second connector 15 to the upper end 1.2 of the windshield wiper 1. [ Figure 2 ] shows some elements of a windshield wiper 1 according to a non-limiting embodiment. The air deflector 14, the vertebra 12 making it possible to apply force to the wiper blade 10, and the shape of the vertebra support 12.1 can be seen. The air deflector 14 is connected to the vertebra support 12.1 in order to mechanically retain it and to the hydraulic channel 15.1 (described below) for the hydraulic function of distributing the washer fluid L. More specifically, the air deflector is fastened to the upper part of the vertebra support 12.1 in order to envelop the vertebra 12.
[0111] The connectors 15 are at a distance from each other, and the central mounting 13 is hinged on each of the connectors 15. The connectors 15 are associated with the vertebrae 12. Each connector 15 is fixed on the vertebrae 12. Each connector 15 is located substantially at the center of each vertebrae 12. Therefore, the pressure applied by the drive arm 3 connected to the central mounting 13 is distributed on the two connectors 15, so that the pressure can be evenly distributed along the wiper blade 10 via the reinforcement member 11. The applied pressure is a force perpendicular to the plane of the windshield wiper 1. In particular, due to the curvature of the wiper blade 10 and because the central mounting 13 is hinged on at least two connectors 12 at a distance from each other, the pressure applied by the drive arm 3 on the central mounting 13 is divided into two. Therefore, the two connectors 15 each transmit half of the pressure applied by the drive arm 3 to the wiper blade 10, in particular via the reinforcement member 11 and each vertebrae 12. Note that each connector 15 is longitudinally arranged at the center or substantially at the center of the vertebrae 12 to which it is fastened. Thus, half of the pressure is transmitted to the longitudinal center of each vertebra 12 of the reinforcing member 11. Thus, the pressure of the drive arm 3 is evenly distributed along the wiper blade 10 via the connector 15 and the reinforcing member 11. In particular, the pressure is applied to the vertebrae 12 so that these vertebrae transmit a constant force to the glass surface 20 of the motor vehicle 2.
[0112] Since the vertebrae 12 have a curvature, when they are placed on the glazing surface 20, they are thereby constrained on the glazing surface 20. In response, there is a uniform pressure distribution because the force is applied at each center of each vertebra 12 by means of two connectors 15. The two connectors 15 make it possible to have two connection points on the wiper blade 10 and the reinforcing member 11, thereby avoiding the need for lateral clearance at the end of the wiper blade 10 (known as wobble, which occurs when there is only one connector 15 and therefore one connection point). In the case of only one connection point, too much force is applied to this connection point, thereby generating wobble. Wobble is a lateral movement that generates vibrations and therefore noise on the glazing surface 20. Therefore, by means of two connectors 15, these vibrations are avoided and the noise is therefore eliminated. It should be noted that this lateral movement increases with the length of the wiper blade 10, especially in a non-limiting example, when the wiper blade has a length equal to 1m.
[0113] It should also be noted that the two connectors 15 make it possible to follow the curvature of the glazing surface 20 more effectively than a single connector 15. To this end, the two connectors are connected together via a secondary pivot (not shown). The secondary pivot allows an angular displacement between plus or minus 5 degrees relative to the longitudinal plane of the windscreen wiper 1. This allows full contact between the wiper blade 10 and the glazing surface 20. This allows for more effective cleaning, in particular in the case of a panoramic glazing surface 20. Specifically, in this case, the end of the windscreen wiper 1 follows the end of the glazing surface 20. Therefore, with the aid of the two connectors 15, cleaning is more effective and there is no risk of the driver's field of vision being disturbed.
[0114] By means of the two connectors 15 and the vertebrae 12, pressure will be applied along the entire length of the windscreen wiper 1. The distribution of force to the two vertebrae 12 is improved. Compared to a windscreen wiper 1 comprising only one vertebra 12 and one connector 15, the wiping quality is maintained.
[0115] The spray device 16 is configured to spray the washer fluid L onto the embedded glass surface 20, and more specifically along the entire length of the windshield wiper. The spray device includes a spray orifice 160. In a non-limiting embodiment, the spray device 16 includes at least one hydraulic manifold 16a, also referred to as a spray manifold 16a. In a non-limiting embodiment, the at least one hydraulic manifold 16a includes a spray orifice 160 in at least one portion, which is configured to allow the washer fluid L to be sprayed.
[0116] In one non-limiting embodiment, the hydraulic manifold 16a has a substantially cylindrical shape. In one non-limiting embodiment, the spray device 16 includes only one hydraulic manifold 16a, which extends along one side of the windshield wiper 1. Therefore, the spray device is a single manifold device. In another non-limiting embodiment, the spray device 16 includes two hydraulic manifolds 16a, which extend along each side of the windshield wiper 1. Therefore, the spray device is a double manifold device. The combined effect of the spray of the washer fluid L and the slightly sweeping motion of the wiper blade 10 makes it possible to eliminate certain particles that may adhere to the embedded glass surface 20, such as splashing mud, dust, and squashed insect residues in the non-limiting example.
[0117] The distribution device 17 for the washer fluid L is configured to distribute said washer fluid L to the injection device 16. The distribution device 17 comprises a supply conduit 170. The supply conduit is connected to the drive arm 3 and connects the windscreen wiper 1 to a pump (not shown) connected to a tank (not shown) of the washer fluid L generally located under the hood of the motor vehicle 2. Thus, the supply conduit 170 supplies the injection device 16 with the washer fluid L.
[0118] Various exemplary embodiments of the windshield wiper 1 are described below.
[0119] according to Figure 3 and Fig.10 In the first non-limiting embodiment shown in FIG. 1 , the air deflector 14 ensures the spraying function. It should be noted that in this first non-limiting embodiment, the central mounting 13 does not ensure the spraying function. The central mounting has no role in spraying the washer fluid L onto the glazed surface 20. Therefore, the central mounting has no spraying orifices 160.
[0120] To this end, according to Figure 3 and Fig.10 In this first non-limiting embodiment illustrated in FIG. 1 , the distribution device 17 comprises a supply duct 170 connected to at least one of the two connectors 15, and the air deflector 14 comprises an injection device 16. Thus, the air deflector 14 comprises said at least one hydraulic manifold 16 a of the injection device 16, and the supply duct 170 is connected to said at least one hydraulic manifold 16 a of the air deflector 14 via at least one of the two connectors 15.
[0121] The supply conduit 170 is indirectly or directly connected to the at least one connector 15. Thus, the at least one connector 15 is configured to feed the washer fluid L to the at least one hydraulic manifold 16a of the injection device 16.
[0122] An embodiment of a single hydraulic manifold 16 a in the injection device 16 is given as a non-limiting example below.
[0123] according to[ Figure 3 ], the supply duct 170 is connected to the two connectors 15 via two feed ducts 18 for the washer fluid L, respectively. These feed ducts 18 are therefore each connected to said supply duct 170 and to each connector 15, respectively. In other words, the windscreen wiper 1 comprises two feed ducts 18 for the washer fluid L, each connected to said supply duct 170 and to each connector 15, respectively. In this case, each connector 15 supplies the washer fluid L directly to the air deflector 14, in particular to the hydraulic manifold 16a. As in [ Figure 4], the two feed ducts 18 are connected to the supply duct 170 via a hydraulic connector 18.1. The hydraulic connector 18.1 thus comprises one inlet and two outlets.
[0124] like Figure 5 and Figure 6 As shown, each connector 15 is connected to a feed conduit 18. Figure 5 ] shows a first connector 15, also referred to as a lower connector 15 or a bottom connector 15, and [ Figure 6 ] shows a second connector 15, also called upper connector 15 or top connector 15. The lower connector 15 is connected to a feed pipe 18, also called lower feed pipe 18. The upper connector 15 is connected to a feed pipe 18, also called upper feed pipe 18.
[0125] like Figure 5 and Figure 6 As shown, each connector 15 comprises a hydraulic channel 15.1 for supplying in each case at least one point of the at least one hydraulic manifold 16a with washer fluid L. In one non-limiting embodiment, the lower connector 15 comprises two hydraulic channels 15.1, namely:
[0126] a further hydraulic channel 15.1 connected to a lower part 16a.1 of the hydraulic manifold 16a and configured to feed the washer fluid L into said lower part 16a.1,
[0127] - A hydraulic channel 15.1 connected to a central part 16a.2 of the hydraulic manifold 16a and configured to feed the washer fluid L into this central part 16a.2.
[0128] In one non-limiting embodiment, the upper connector 15 comprises two hydraulic channels 15.1, namely:
[0129] a hydraulic channel 15.1 configured to feed the washer fluid L into the upper part 16a.3 of the hydraulic manifold 16a,
[0130] - A further hydraulic channel 15.1 which is connected to a central part 16a.2 of the hydraulic manifold 16a and is configured to feed the washer fluid L into this central part 16a.2.
[0131] like[ Figure 5 ], the lower connector 15 also includes a sleeve 15.2, which is configured to be connected to the lower feed pipe 18. Figure 6 ] As shown, the upper connector 15 also includes a sleeve 15.2, which is configured to be connected to the upper feed pipe 18.
[0132] In one non-limiting embodiment, the hydraulic manifold 16a includes injection orifices 160 in two locations thereof. The hydraulic manifold 16a includes a lower portion 16a.1 (also referred to as a bottom portion 16a.1 ([ Figure 7 ] shown)), central part 16a.2([ Fig. 9 ] shown), and the upper portion 16a.3 (also referred to as the top portion 16a.3 ([ Figure 8 ] shown)).
[0133] In one non-limiting embodiment, the lower portion 16a.1 and the upper portion 16a.3 include injection orifices 160. For simplicity, Figure 7 and Figure 8 In the drawings, only some of the injection orifices 160 are provided with reference numerals. In one non-limiting embodiment, the central portion 16a.2 has no injection orifices 160.
[0134] The lower connector 15 is configured to feed the washer fluid L in particular to the lower part 16a.1 of the hydraulic manifold 16a. The upper connector 15 is configured to feed the washer fluid L in particular to the upper part 16a.3 of the hydraulic manifold 16a. It should be noted that, although both connectors 15 feed the washer fluid L into the central part 16a.2 of the hydraulic manifold 16a, this central part 16a.2 is not used for the injection function because it does not include the injection orifice 160. Of course, in another non-limiting embodiment, each connector 15 can be combined with only one hydraulic channel 15.1 for supplying only one part of the hydraulic manifold 16a that ensures the injection function, i.e. the part with the injection orifice 160.
[0135] Thus, according to this first non-limiting embodiment variant, the washer fluid L is distributed at two points via the two connectors 15. This first non-limiting embodiment variant allows a good distribution of the washer fluid L in the windscreen wiper 1 .
[0136] according to[ Fig.10 ], the supply duct 170 is directly connected to a single connector 15. In other words, the windscreen wiper 1 does not comprise an intermediate feed duct 18 for the washer fluid L. In this case, the single connector 15 distributes the washer fluid L directly to the air deflector 14, i.e. to the hydraulic manifold 16a. As in [ Fig.11 ], the supply conduit 170 is directly connected to the first connector 15 (in this case the lower connector 15).
[0137] As in the case of the first non-limiting embodiment variant, in one non-limiting embodiment, the hydraulic manifold 16a comprises injection orifices 160 in two of its regions, namely in the lower region 16.1 and in the upper region 16.3.
[0138] The single connector 15, in this case the lower connector 15, comprises a hydraulic channel 15.1 for supplying washer fluid L to at least one location 16.1 of the at least one hydraulic manifold 16a.
[0139] like[ Fig.11 ] As shown, the lower connector 15 is therefore configured to feed the washer fluid L to the lower portion 16a.1 of the hydraulic manifold 16a, to the central portion 16a.2 and also to the upper portion 16a.3.
[0140] Therefore, the lower connector 15 comprises two hydraulic channels 15.1, namely:
[0141] a hydraulic channel 15.1 connected to a lower part 16.1 of the hydraulic manifold 16a and configured to feed the washer fluid L into this lower part 16a.1,
[0142] - A further hydraulic channel 15.1 connected to the central part 16a.2 of the hydraulic manifold 16a and configured to supply washer fluid L to the central part 16.2 and to the upper part 16a.3 of the hydraulic manifold 16a.
[0143] It should be noted that in this case a sufficiently powerful pump (not shown) is needed to deliver the washer fluid L into the upper region 16a.3, said pump being located under the bonnet of the motor vehicle 2 and connected to the tank.
[0144] In one non-limiting embodiment, the lower connector 15 further comprises a sleeve 15 . 2 , this time configured to be directly connected to the supply pipe 170 .
[0145] [ Fig.12] illustrates a second connector 15, referred to as an upper connector. The upper connector 15 comprises two hydraulic channels 15.1, which are respectively connected to a central portion 16a.2 and an upper portion 16a.3 of the hydraulic manifold 16a. The two hydraulic channels 15.1 are configured to transfer the washer fluid L, which has been fed into the central portion 16a.2, from the central portion 16a.2 of the hydraulic manifold 16a to the upper portion 16a.3 through the lower connector 15. The washer fluid L is thus transferred from one portion of the hydraulic manifold 16a to another portion via the hydraulic channels 15.1. In particular, the washer fluid L is transferred from the central portion 16a.2 to the upper portion 16a.3 via the two hydraulic channels 15.1 of the upper connector 15.
[0146] In a non-limiting embodiment, the upper connector 15 has no inlet for the scrubber fluid L. To this end, in a non-limiting embodiment variant, the upper connector 15 also includes a sleeve 15.2, which is configured to be closed with a plug 15.4. This prevents the scrubber fluid L from escaping to the outside, and this makes it possible to use the same standard part for the lower connector 15 and the upper connector 15.
[0147] Thus, according to this second non-limiting embodiment variant, the washer fluid L is distributed at a single point via one of the two connectors 15, in this case the lower connector 15. Of course, in another non-limiting embodiment, it could be an upper connector 15 that feeds the washer fluid L to the lower portion 16.1, the central portion 16.2, and the upper portion 16.3 of the hydraulic manifold 16a. In this case, the supply pipe 170 is directly connected to this upper connector 15.
[0148] According to a second non-limiting embodiment, the central mounting 13 ensures all or part of the function of spraying the washer fluid L onto the glazed surface 20. To this end, according to Figures 13 to 28 In this second non-limiting embodiment shown in FIG. 1 , the distribution device 17 comprises a supply conduit 170 connected to the central mounting 13, and the central mounting 13 comprises all or part of the injection device 16. Fig.14 ] bottom view and [ Fig.15 ] and a close-up view of [ Fig.21 ]and[ Fig. 27 ], the supply pipe 170 is connected to the central mounting 13 via the sleeve 13.1.
[0149] according to Figures 13 to 17 In the first non-limiting embodiment variant shown in FIG. 1 , the central mounting 13 ensures the entire injection function. To this end, the central mounting 13 includes the entire injection device 160. Thus, as shown in [ Fig.16 ]and Fig.17 As shown, the central mounting 13 includes at least one hydraulic manifold 16a including injection orifices 16. Fig.16 and Fig.17 Only some of the injection orifices 160 are provided with reference numerals. Fig.17 ], in a non-limiting embodiment, the at least one hydraulic manifold 16a comprises injection orifices 160 along its entire length. This makes it possible to inject the washer liquid L via all the parts 16.1, 16.2 and 16.3 of the hydraulic manifold 16a along its entire length.
[0150] like Fig.18 and Fig.19 As shown, the air deflector 14 has a lower portion 14.1 ([ Fig.18 ]), in its central part 14.2 ([ Fig.18 ]), or in its upper section 14.3 ([ Fig.19 ] does not include any injection orifice 160. Therefore, it cannot ensure the function of injection.
[0151] according to Figures 20 to 28 In a second non-limiting embodiment variant shown in , the central mounting 13 ensures a part of the injection function and the air deflector 14 ensures a part of the injection function. Thus, the central mounting 13 comprises a part of an injection device 16 and the air deflector 14 comprises a part of the injection device 16. The injection device 16 comprises at least one main hydraulic manifold 16a forming part of the central mounting 13 and at least one secondary hydraulic manifold 16b forming part of the air deflector 14.
[0152] In the first embodiment illustrated in the figures of this second non-limiting embodiment variant, the injection device 16 comprises a primary hydraulic manifold 16a forming part of the central mounting 13, and a secondary hydraulic manifold 16b forming part of the air deflector 14. In a non-limiting embodiment, the primary hydraulic manifold 16a and the secondary hydraulic manifold 16b extend on the same side of the windscreen wiper 1. Thus, there is a single manifold central mounting 13 and a single manifold air deflector 14.
[0153] In a second non-limiting embodiment, not shown, of this second non-limiting embodiment variant, the spraying device 16 comprises two main hydraulic manifolds 16a and two secondary hydraulic manifolds 16b, and the supply conduit 170 is connected to the central mounting 13, which is configured to feed the washer fluid L to the two secondary hydraulic manifolds 16b of the air deflector 14 via two connectors 15, respectively. Thus, there is a central mounting 13 known as a dual-manifold central mounting. Thus, there is also an air deflector 14 known as a dual-manifold air deflector. This makes it possible to enhance the washing of the paneled glass surface 20. Two main hydraulic manifolds 16a each extend along each side of the central mounting 13, and two secondary hydraulic manifolds 16b each extend along each side of the air deflector 14.
[0154] In a non-limiting embodiment, the two main hydraulic manifolds 16a are activated alternately according to the movement of the windshield wiper 1. This makes it possible to reduce the time for cleaning the embedded glass surface 20, thereby improving the washing effectiveness by spraying more washer fluid L. Activation means that the main hydraulic manifold 16a sprays the washer fluid L onto the embedded glass surface 20. When the main hydraulic manifold is deactivated, the washer fluid L is not sprayed. Therefore, when the movement of the windshield wiper 1 is upward, one main hydraulic manifold 16a is activated, and when the movement of the windshield wiper 1 is downward, the other main hydraulic manifold 16a is activated. The same is true for the secondary hydraulic manifold 16b. In a non-limiting embodiment, the two secondary hydraulic manifolds 16b are activated alternately depending on the movement of the windshield wiper 1. This makes it possible to reduce the time for washing the embedded glass surface 20. Activation means that the secondary hydraulic manifold 16b sprays the washer fluid L onto the embedded glass surface 20. When the secondary hydraulic manifold is deactivated, the washer fluid L is not sprayed. Therefore, when the movement of the windshield wiper 1 is upward, one secondary hydraulic manifold 16 b is activated, and when the movement of the windshield wiper 1 is downward, the other secondary hydraulic manifold 16 b is activated.
[0155] A single manifold center mount and a single manifold air deflector 14 are given as non-limiting examples in the remainder of this description.
[0156] In addition, if Fig.21 and Fig. 22 As shown, the distribution device 17 also comprises a feed duct 171 connected to the central mounting 13 and to at least one of the two connectors 15. Figure 21 to Figure 24In the non-limiting example shown, this connector 15 is a lower connector 15. Thus, the washer fluid L is distributed into the secondary hydraulic manifold 16 b by means of the lower connector 15. Thus, the central mounting 13 feeds the washer fluid L to the secondary hydraulic manifold 16 b of the air deflector 14 via the lower connector 15.
[0157] In other words, if Fig.21 and Fig. 27 As shown, the central mounting 13 includes the at least one main hydraulic manifold 16a, which includes injection orifices 160. For the sake of simplicity, only some of the injection orifices 160 are provided with reference numerals in the drawings. Fig. 27 ] In a non-limiting embodiment, the at least one hydraulic manifold 16a comprises injection orifices 160 along its entire length. This makes it possible to inject the washer liquid L via all the parts 16a.1, 16a.2 and 16a.3 of the main hydraulic manifold 16a along its entire length.
[0158] In other words, if Fig.21 , Fig.25 and Fig.26 As shown, the air deflector 14 comprises the at least one secondary hydraulic manifold 16b comprising injection orifices 160. For the sake of simplicity, only some of the injection orifices 160 are provided with reference numerals in the figures.
[0159] like[ Fig.21 ], the supply pipe 170 is connected to the central mounting 13 via the sleeve 13.1. Fig. 22 ], the feed pipe 171 is connected to the connector 15 via the sleeve 15.3, which is used to feed the washer fluid L into the secondary hydraulic manifold 16b. Fig.21 ] As shown, a feed pipe 171 is connected to the central mounting 13 via a bushing 13.3. Thus, the scrubber fluid L is transferred from the central mounting 13 to the connector 15 via this feed pipe 171.
[0160] like Fig.23 and Fig.24 As shown in the section in , the sleeve 15.3 is continued by a hydraulic channel 15.4 which is connected to at least one other hydraulic channel 15.1.
[0161] like Fig. 22 , Fig.23 and Fig.24, this further hydraulic channel 15.1 is configured to supply the secondary hydraulic manifold 16b with washer fluid L. The at least one connector 15 for supplying washer fluid L, in this case the lower connector 15, thus comprises at least one hydraulic channel 15.1.
[0162] As illustrated in the non-limiting example, the injection device 16 comprises one secondary hydraulic manifold 16a, and the supply pipe 170 is connected to the central mounting 13 configured to feed the washer fluid L to the secondary hydraulic manifold 16b of the air deflector 14 via one of the two connectors 15. Thus, there is an air deflector 14 referred to as a single-manifold air deflector.
[0163] Therefore, if [ Fig.25 ], the air deflector 14 comprises a first portion of the secondary hydraulic manifold 16b, also referred to as the lower portion 16b.1. Fig.26 ], the air deflector 14 comprises a second portion of the secondary hydraulic manifold 16b, also referred to as the upper portion 16b.3. Fig.25 ], the lower portion 16b.1 comprises a plurality of spray orifices 160 extending from the lower end 1.1 of the windscreen wiper 1 to the lower connector 15. The lower portion 16b.1 is thus part of the lower part 14.1 of the air deflector 14. As shown in [ Fig.26 ], the upper region 16b.3 comprises a plurality of injection orifices 160 extending from the upper end 1.2 of the windshield wiper 1 to the upper connector 15. The upper region 16b.3 is thus part of the upper portion 14.3 of the air deflector 14. Thus, the lower region 16b.1 makes it possible to inject the washer fluid L into the lower portion of the windshield wiper 1, and the upper region 16b.3 makes it possible to inject the washer fluid into the upper portion of the windshield wiper 1. As shown in [ Fig. 22 ] As shown, the at least one connector 15 includes a first hydraulic channel 15.1 and a second hydraulic channel 15.1, the first hydraulic channel being configured to supply washer fluid L to a lower portion 16b.1 of a secondary hydraulic manifold 16b, and the second hydraulic fluid channel being configured to supply washer fluid L to an upper portion 16b.3 of the secondary hydraulic manifold 16b.
[0164] It should be noted that in this non-limiting embodiment variant, as [ Fig.28 ] As shown, the air deflector 14 comprises a central portion 14.2 having a portion of the secondary hydraulic manifold 16b.2 without injection orifices 160. Of course, in another non-limiting embodiment variant, there may be a central portion 16b.2 of the secondary hydraulic manifold 16b comprising injection orifices 160.
[0165] exist Figures 29 to 34 In the third non-limiting embodiment shown, the air deflector 14 ensures the entire spraying function. In this case, the central mounting 13 does not ensure the spraying function. Fig.30 and Fig.31 As shown, the central mounting 13 therefore does not include any injection orifice 160. It will be noted that by replacing reference numeral 16b.1 with reference numeral 16.1 and reference numeral 16b.3 with reference numeral 16.3, Figure 22 to Figure 24 The same applies to this third non-limiting embodiment.
[0166] To this end, the air deflector 14 comprises injection means 16 and the distribution means 17 comprises:
[0167] - a supply duct 170 connected to said central mounting 13, and
[0168] A feed duct 171 connected to the central mounting 13 and to at least one of the two connectors 15 .
[0169] In other words, the air deflector 14 includes at least one hydraulic manifold 16a, which includes Fig.31 , Fig.32 and Fig.33 The injection orifice 160 shown in FIG.
[0170] In a first embodiment variant of this third embodiment illustrated in the drawings, the injection device 16 comprises one hydraulic manifold 16a forming part of the air deflector 14, and the supply duct 170 is connected to the central mounting 13 configured to feed the washer fluid L to the hydraulic manifold 16a of the air deflector 14 via one of the two connectors 15. Thus, there is an air deflector 14 referred to as a single-manifold air deflector.
[0171] In a second embodiment variant, not shown, of this third embodiment, the spray device 16 comprises two hydraulic manifolds 16a forming part of the air deflector 14, and the supply duct 170 is connected to the central mounting 13, which is configured to feed the washer fluid L to the two hydraulic manifolds 16a of the air deflector 14 via two connectors 15, respectively. Thus, there is also an air deflector 14 known as a dual-manifold air deflector. This makes it possible to enhance the washing of the paneled glass surface 20. The two hydraulic manifolds 16a each extend along each side of the air deflector 14. In a non-limiting embodiment, the two hydraulic manifolds 16a are activated alternately depending on the movement of the windscreen wiper 1.
[0172] In the remainder of the description, a single manifold air deflector 14 is given as a non-limiting example.
[0173] In addition, as Fig.30 ], the distribution device 17 also comprises a feed duct 171 connected to the central mounting 13 and to at least one of the two connectors 15. In the non-limiting example illustrated, this connector 15 is the lower connector 15. Thus, the washer fluid L is distributed into the at least one hydraulic manifold 16a by means of the lower connector 15. Thus, the central mounting 13 feeds the washer fluid L to the hydraulic manifold 16a of the air deflector 14 via the lower connector 15.
[0174] like[ Fig.30 ], the supply pipe 170 is connected to the central mounting 13 via the sleeve 13.1. Fig. 22 ], the feed pipe 171 is connected to the connector 15 via the sleeve 15.3, which is used to feed the washer fluid L into the hydraulic manifold 16a. Fig.30 ] As shown, a feed pipe 171 is connected to the central mounting 13 via a bushing 13.3. Thus, the scrubber fluid L is transferred from the central mounting 13 to the connector 15 via this feed pipe 171.
[0175] like Fig.23 and Fig.24 As shown in the section in , the sleeve 15.3 is continued by a hydraulic channel 15.4 which is connected to at least one other hydraulic channel 15.1.
[0176] like Fig. 22 , Fig.23 and Fig.24 , this further hydraulic channel 15.1 is configured to supply the hydraulic manifold 16a with washer fluid L. The at least one connector 15 for supplying washer fluid L, in this case the lower connector 15, thus comprises at least one hydraulic channel 15.1.
[0177] like[ Fig.32 ], the air deflector 14 comprises a first portion of the hydraulic manifold 16a.1, also referred to as the lower portion 16a.1. Fig.33 ], the air deflector 14 comprises a second portion of the hydraulic manifold 16a.3, also referred to as the upper portion 16a.3. Fig.32 ], the lower portion 16a.1 comprises a plurality of spray orifices 160 extending from the lower end 1.1 of the windscreen wiper 1 to the lower connector 15. The lower portion 16a.1 is thus part of the lower part 14.1 of the air deflector 14. As shown in [ Fig.33 ], the upper region 16a.3 comprises a plurality of injection orifices 160 extending from the upper end 1.2 of the windscreen wiper 1 to the upper connector 15. The upper region 16a.3 is thus part of the upper portion 14.3 of the air deflector 14. Thus, the lower region 16a.1 makes it possible to inject the washer fluid L into the lower portion of the windscreen wiper 1, and the upper region 16a.3 makes it possible to inject the washer fluid into the upper portion of the windscreen wiper 1. As shown in [ Fig. 22 ] As shown, the at least one connector 15 includes a first hydraulic channel 15.1 and a second hydraulic channel 15.1, the first hydraulic channel being configured to supply washer fluid L to a lower portion 16a.1 of the hydraulic manifold 16a, and the second hydraulic fluid channel being configured to supply washer fluid L to an upper portion 16a.3 of the hydraulic manifold 16a.
[0178] It should be noted that in this non-limiting embodiment variant, as [ Fig.31 ] As shown, the air deflector 14 comprises a central portion 14.2 having a portion of the secondary hydraulic manifold 16a.2 without injection orifices 160. Of course, in another non-limiting embodiment variant, there may be a central portion 16a.2 of the hydraulic manifold 16a comprising injection orifices 160.
[0179] Of course, the description of the invention is not limited to the above-described embodiments and fields. Thus, in another non-limiting embodiment of a second non-limiting embodiment variant of the second non-limiting embodiment, there may be a combination of a double manifold central mount and a single manifold deflector, or vice versa. Thus, in another non-limiting embodiment, the reinforcement member 11 comprises three vertebrae connected together by an intermediate mount, the three vertebrae having three connectors. In this case, the air deflector 14 is composed of more than three parts.
[0180] The invention thus described has the following advantages, among others:
[0181] - the method makes it possible to combine the wiping function and the washing function with the washer fluid L into a single structure by incorporating the injection device 16 into the windscreen wiper 1;
[0182] - by means of the two connectors 15 and the spray device 16 integrated into the windscreen wiper 1 , washing is more effective than in the prior art in which the spray device is integrated into the region of the bonnet of the motor vehicle 2 ;
[0183] - the method makes it possible to better follow the curve of the glazed surface 20 when it is sprayed with the washer fluid L,
[0184] - the method makes it possible to have a more robust long windscreen wiper 1,
[0185] - This method allows the drive arm 3 to distribute well the pressure on the windscreen wiper 1. Thus, in the non-limiting example of a very significant curvature of the glazing surface 20, this method makes it possible to adapt complex glazing surfaces 20 with very significant curvatures, such as super sports cars, trucks;
[0186] - the method makes it possible to generate pressure on the end of the windscreen wiper 1 so as to bear on the end of the glazing surface 20 and thus follow the curvature of a small or large glazing surface 20 , in particular a panoramic windscreen. Cleaning is thus more effective;
[0187] By means of the different embodiments described, the method makes it easier to replace components of the windscreen wiper 1 and to connect the supply line 170 .
