[0044] Unless otherwise specified, identical structural or functional elements appearing in different drawings shall be given the same reference numeral.
[0045] A windshield wiper 1 for a vehicle 2 according to the present invention will be described with reference to Figures 1 to 34 in non-limiting embodiments. In one non-limiting embodiment, vehicle 2 is an automobile. Automobile is understood to mean any type of motorized vehicle. This embodiment is made as a non-limiting example in the following description. Therefore, in the following description, vehicle 2 will also be referred to as automobile 2.
[0046] In the following explanation, the terms “longitudinal direction” and “lateral direction” are based on the windshield wiper 1. The longitudinal direction corresponds to the main axis from which the windshield wiper extends, and the lateral direction corresponds to a straight line of the same direction, i.e., a straight line that intersects the longitudinal direction, and in particular a straight line perpendicular to its longitudinal axis in the plane from which the windshield wiper 1 rotates.
[0047] Automobile 2 has a glass surface 20 that requires wiping and washing. In one non-limiting embodiment, the glass surface 20 is the windshield of automobile 2.
[0048] Figure 1 shows an exploded view of the windshield wiper 1. The windshield wiper 1 is a flat windshield wiper, also known as a "flat blade".
[0049] Windshield wiper 1 is, - At least one wiper blade 10, - A reinforcing member 11 comprising a berdibra support 12.1 and at least one berdibra 12, - Two connectors 15 fixed to at least one of the berdibra 12, - A central mounting portion 13 is articulated to each of the two connectors 15, - Air deflector 14 connected to the Birdibra support 12.1, - Spraying device 16, - Distributor 17 for washer fluid L, It is equipped with.
[0050] As shown in Figure 1, the windshield wiper 1 is defined by a lower end 1.1, also called a bottom end 1.1, and an upper end 1.2, also called a top end 1.2. These two ends form the ends of the wiper blade 10. Ends 1.1 and 1.2 enable the integral fixing of parts 14 and 12, and also allow for the spraying device 16 to Hydraulic pressure This is an end piece that allows the two ends of manifold 16a (described later) to be closed.
[0051] The wiper blade 10 is configured to wipe the glass surface 20 of the automobile 2. It is generally made of elastomer and is held along its entire length. The windshield wiper 1 is generally fastened to a drive arm 3, which is driven by a motor to reciprocate at an angle, as shown in Figure 1. Thus, the wiper blade 10 is configured to wipe the glass surface 20 by rubbing it during such angled reciprocating motion, and at the same time carry and remove the washer fluid L from the driver's field of view of the automobile 2.
[0052] The reinforcing member 11, having a berdibra support 12.1 and at least one of the berdibra 12, can reinforce the wiper blade 10 to facilitate contact of the wiper blade 10 with the glass surface 20. The reinforcing member 11 distributes the load-bearing force on the drive arm 3 along the wiper blade 10. Thus, it can transmit the pressure of the drive arm 3 by distributing it along the length of the windshield wiper 1. At least one of the berdibra 12 is a longitudinal berdibra. It has a radius of curvature. Therefore, it is not flat. Furthermore, the berdibra 12 is curved, and this curve gives the wiper blade 10 a curved shape when it remains pressed against the glass surface 10. In other words, it is the berdibra 12 that gives the wiper blade 10 its curvature. Thus, the reinforcing member 11 ensures that the wiper blade 10 follows the curved shape of the glass surface 20, which is the windshield of the automobile 2, for example in a non-limiting example. In one non-limiting embodiment, the berdibra 12 is made of metal. This allows the wiper blade 10 to be curved while reinforcing it. The berdibra support 12.1 is configured to support at least one of the berdibra 12 and the wiper blade 10.
[0053] In one non-limiting embodiment, the reinforcing member 11 comprises two berdibras 12. Thus, the berdibra support 12.1 is configured to support the two berdibras 12. They are positioned with their ends facing each other through their longitudinal ends. In one non-limiting embodiment, the two berdibras 12 have different radii of curvature, allowing them to exert different forces along the wiper blade 10. In one non-limiting embodiment modification, the first berdibra 12, referred to as the lower berdibra 12, is flatter than the more curved second berdibra 12, referred to as the upper berdibra 12. The lower berdibra 12 is closest to the drive arm 3. In one non-limiting embodiment, the two berdibras 12 have different lengths. In one non-limiting embodiment modification, the lower berdibra 12 is longer than the shorter upper berdibra 12. In one non-limiting embodiment, two berdibra 12 are aligned on a berdibra support 12.1.
[0054] The central mounting portion 13 is configured to be fastened to the drive arm 3. The central arm 13 is joined to the end component 30 (shown in Figure 1) of the drive arm 3 via a central pivot axis. In one non-limiting embodiment, the drive arm 3 includes an end component 30 that is crimped to a rod 31 connected to a casing 32. Thus, the end component 30 functions as a connection between the rod 31 and the central mounting portion 13. In one non-limiting exemplary embodiment, the central pivot axis is configured to result in 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 includes an end component 30 integrated with the casing 32. In this case, the rod 31 is absent.
[0055] In one non-limiting embodiment, the central mounting portion 13 is articulated to each of the connectors 15 via a swivel connector. The swivel connector extends perpendicular to the longitudinal axis of the windshield wiper 1. In one non-limiting example, the swivel connector is realized by the cooperation of a pin 151 (e.g., shown in Figure 1 or Figure 12) projecting laterally from either side of the connector 15 and an opening 131 (e.g., shown in Figure 4) in the central mounting portion 13 configured to receive the pin 151. The swivel connector allows the central mounting portion 13 to rotate relative to the connectors 15 in a plane perpendicular to the rotation plane of the windshield wiper 1. Having two connectors 15 allows for better localized distribution of pressure on the burrower 12.
[0056] In one non-limiting embodiment, the central mounting portion 13 includes an air deflection surface 130. This air deflection surface 130 can convert the aerodynamic force generated on the windshield wiper 1 into a downward force that presses the windshield wiper 1 against the glass surface 20, ensuring effective high-speed wiping and cleaning. The central mounting portion 13 is also configured to hold two connectors 15. The air deflector 14 is an aerodynamic deflector. The aerodynamic deflector increases the force with which the wiper blade 10 contacts the glass surface 20 to be wiped, utilizing the relative airflow of the automobile 2. As shown in Figure 1, in one non-limiting embodiment, the air deflector 14 consists of at least three parts. Thus, it comprises a lower part 14.1, also referred to as a bottom part 14.1, a middle part 14.2, and an upper part 14.3, also referred to as a 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 middle 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. A cross-sectional view in Figure 2 shows some of the elements of the windshield wiper 1 according to one non-limiting embodiment. The shape of the air deflector 14, the bird blister 12 which can apply force to the wiper blade 10, and the bird blister support 12.1 are visible. The air deflector 14 is connected to the bird blister support 12.1 to mechanically hold it and distribute the washer fluid L. Hydraulic pressure For functionality Hydraulic pressure It is connected to channel 15.1 (described later). More specifically, the air deflector is fastened to the top of the berdibra support 12.1 and surrounds the berdibra 12.
[0057] The connectors 15 are spaced apart from each other, and the central mounting section 13 is articulated to each of the connectors 15. The connectors 15 are associated with the berdibras 12. Each connector 15 is fixed to the berdibras 12. Each connector 15 is positioned approximately in the center of each berdibra 12. Therefore, the pressure exerted by the drive arm 3 connected to the central mounting section 13 is distributed across the two connectors 15, so that the pressure can be uniformly distributed along the wiper blade 10 via the reinforcing member 11. This exerted pressure is a force perpendicular to the plane of the windshield wiper 1. Specifically, due to the curvature of the windshield wiper 10, and because the central mounting section 13 is articulated to at least two spaced-apart connectors 15, the pressure exerted from the drive arm 3 on the central mounting section 13 is divided into two. Therefore, the two connectors 15 each transmit half of the pressure exerted by the drive arm 3 to the wiper blade 10, particularly through the reinforcing member 11 and each wing bladder 12. Note that each connector 15 is positioned approximately in the center in the longitudinal direction of the wing bladder 12 to which it is fastened. Thus, half of the pressure is transmitted to the center of each wing bladder 12 in the longitudinal direction of the reinforcing member 11. As a result, the pressure from the drive arm 3 is uniformly distributed along the wiper blade 10 through the connectors 15 and the reinforcing member 11. In particular, pressure is applied to the wing bladder 12 so that it transmits a constant force against the glass surface 20 of the automobile 2.
[0058] Because the berdibra 12 is curved, when placed on the glass surface 20, it is constrained on the glass surface 20. Accordingly, the force is applied to each center of each berdibra 12 by the two connectors 15, resulting in uniform pressure distribution. The two connectors 15 provide two connection points to the wiper blade 10 and the reinforcing member 11, thus avoiding the need to address lateral clearance, known as sculling, at the end of the wiper blade 10. This is necessary when there is only one connector 15, and therefore only one connection point. With only one connection point, excessive force is applied to this connection point, causing sculling. Sculling is a lateral movement on the glass surface 20 that generates vibration and, consequently, noise. Therefore, the two connectors 15 avoid vibration and, consequently, eliminate noise. Note that this lateral movement increases with the length of the wiper blade 10, especially when the wiper blade 10 has a length equal to 1 m in one non-limiting example.
[0059] Furthermore, it should be noted that the two connectors 15 allow for more effective tracking of the curvature of the glass surface 20 than a single connector 15. For this purpose, they are connected to each other via a secondary pivot axis (not shown). The secondary pivot axis allows for displacement of the windshield wiper 1 at an angle of +5 to -5 degrees relative to the longitudinal plane. This ensures sufficient contact between the wiper blade 10 and the glass surface 20. Therefore, more effective cleaning is achieved, especially in the case of a panoramic glass surface 20. Specifically, in this example, the end of the windshield wiper 1 follows the end of the glass surface 20. Thus, the two connectors 15 make cleaning more effective without obstructing the driver's view.
[0060] The two connectors 15 and the berdibra 12 allow pressure to be applied along the entire length of the windshield wiper 1. This improves the distribution of force to the two berdibra 12. Wiping quality is maintained compared to a windshield wiper 1 with only one berdibra 12 and only 15 connectors.
[0061] The spraying device 16 is configured to spray washer fluid L onto the glass surface 20, more specifically along the entire length of the windshield wiper. It comprises a spray orifice 160. In one non-limiting embodiment, the spraying device 16 comprises at least one spray manifold 16a, also referred to as a spray manifold 16a Hydraulic pressure The manifold 16a is provided. In one non-limiting embodiment, at least one of the above Hydraulic pressure The manifold 16a is equipped in at least part with a spray orifice 160 configured to spray washer fluid L.
[0062] In one non-limiting embodiment, Hydraulic pressure The manifold 16a has a substantially cylindrical shape. In one non-limiting embodiment, the spraying device 16 extends along one side of the windshield wiper 1. Hydraulic pressure It comprises only one manifold 16a. Thus, this is a single-type manifold device. In another non-limiting embodiment, the spray device 16 has two extending along each side of the windshield wiper 1 Hydraulic pressure The system is equipped with a manifold 16a. Therefore, it is a double manifold system. The combination of the spraying of washer fluid L and the sweeping movement of the wiper blade 10 can remove certain particles that may adhere to the glass surface 20, such as splashed mud, dust, crushed insect remains, etc., in non-limiting examples.
[0063] The washer fluid L distribution device 17 is configured to distribute the washer fluid L to the spray device 16. The distribution device 17 includes a supply pipe 170, which is connected to the drive arm 3 and to a pump (not shown) that connects the windshield wiper 1 to a tank (not shown) of washer fluid L, which is usually located under the hood of the automobile 2. Thus, the supply pipe 170 supplies the washer fluid L to the spray device 16.
[0064] Various embodiments of the windshield wiper 1 are described below.
[0065] According to the first non-limiting embodiment shown in Figures 3 and 10, the air deflector 14 performs the spraying function. Note that in this first non-limiting embodiment, the central mounting portion 13 does not perform the spraying function. It does not play any role in spraying the washer fluid L onto the glass surface 20. Therefore, it does not have a spray orifice 160.
[0066] For this purpose, according to a first non-limiting embodiment shown in Figures 3 and 10, the distribution device 17 comprises a supply pipe 170 connected to at least one of two connectors 15, and the air deflector 14 comprises a spraying device 16. Thus, the air deflector 14 comprises at least one of the spraying devices 16. Hydraulic pressure The manifold 16a is provided, and the supply pipe 170 is connected to at least one of the air deflectors 14. Hydraulic pressure The manifold 16a is connected via at least one of the two connectors 15.
[0067] The supply pipe 170 is indirectly or directly connected to at least one connector 15. Thus, at least one of the connectors 15 supplies the washer fluid L to at least one of the sprayers 16. Hydraulic pressure It is configured to transport to manifold 16a.
[0068] Single Hydraulic pressureThe following are non-limiting examples of embodiments of the manifold 16a.
[0069] According to a modified version of the first non-limiting embodiment shown in Figure 3, the supply pipe 170 is connected to two connectors 15 via two transport pipes 18 for the washer fluid L, respectively. Thus, these transport pipes 18 are each connected to the supply pipe 170 and each connector 15. In other words, the windshield wiper 1 is equipped with two transport pipes 18 for the washer fluid L, which are each connected to the supply pipe 170 and each connector 15, respectively. In this example, each connector 15 supplies the washer fluid L to the air deflector 14, in particular Hydraulic pressure The material is directly transported to the manifold 16a. As shown in Figure 4, the two transport pipes 18 are connected to the supply pipe 170. Hydraulic pressure It is connected via connector 18.1. Therefore, Hydraulic pressure Connector 18.1 has one inlet and two outlets.
[0070] As shown in Figures 5 and 6, each connector 15 is connected to a transport pipe 18. Figure 5 shows the first connector 15, also called the lower connector 15 or bottom connector 15, and Figure 6 shows the second connector 15, also called the upper connector 15 or top connector 15. The lower connector 15 is connected to a transport pipe 18, also called the lower transport pipe 18. The upper connector 15 is connected to a transport pipe 18, also called the upper transport pipe 18.
[0071] As shown in Figures 5 and 6, each connector 15 has at least one of the above Hydraulic pressure For supplying washer fluid L to at least a portion of the manifold 16a Hydraulic pressure It has a channel 15.1. In one non-limiting embodiment, the lower connector 15 has two Hydraulic pressure Channel 15.1, that is, - Hydraulic pressure Another connection to the lower part 16a.1 of manifold 16a Hydraulic pressureChannel 15.1, configured to transport washer fluid L to the lower portion 16a.1 Hydraulic pressure Channel 15.1 and, - Hydraulic pressure Connect to the central part 16a.2 of manifold 16a.

[0072] In one non-limiting embodiment, the upper connector 15 has two Hydraulic pressure Channel 15.1, that is, - Washer fluid L Hydraulic pressure The upper portion 16a.3 of the manifold 16a is configured to transport the material. Hydraulic pressure Channel 15.1 and, - Hydraulic pressure Another connection to the central part 16a.2 of manifold 16a Hydraulic pressure Channel 15.1, configured to transport the washer fluid L to this central portion 16a.2 Hydraulic pressure Channel 15.1 and, It is equipped with.
[0073] As shown in Figure 5, the lower connector 15 further comprises a cannula 15.2 configured to connect to the lower transport pipe 18. As shown in Figure 6, the upper connector 15 further comprises a cannula 15.2 configured to connect to the upper transport pipe 18.
[0074] In one non-limiting embodiment, Hydraulic pressure The manifold 16a is equipped with spray orifices 160 in two of its sections. Hydraulic pressure The manifold 16a comprises a lower portion 16a.1 (shown in Figure 7), also referred to as the bottom portion 16a.1, a central portion 16a.2 (shown in Figure 9), and an upper portion 16a.3 (shown in Figure 8), also referred to as the top portion 16a.3.
[0075] In one non-limiting embodiment, the lower portion 16a.1 and the upper portion 16a.3 are provided with a spray orifice 160. For simplicity, only some of the spray orifices 160 are given reference numerals in Figures 7 and 8. In one non-limiting embodiment, the central portion 16a.2 does not have a spray orifice 160.
[0076] The lower connector 15 is for the washer fluid L, in particular Hydraulic pressure It is configured to transport the washer fluid L to the lower portion 16a.1 of the manifold 16a. The upper connector 15 is configured to transport the washer fluid L, in particular Hydraulic pressure It is configured to transport the washer fluid L to the upper portion 16a.3 of the manifold 16a. Two connectors 15 are configured to transport the washer fluid L Hydraulic pressure Although the fluid is transported to the central portion 16a.2 of the manifold 16a, it should be noted that this central portion 16a.2 does not have a spray orifice 160 and is therefore not used for misting applications. Naturally, in another non-limiting embodiment, each connector 15 is Hydraulic pressure For supplying only to a portion of the manifold 16a that is responsible for the spraying function, that is, only to the portion that has the spray orifice 160. Hydraulic pressure It is sufficient to include only one channel 15.1.
[0077] Therefore, according to the first non-limiting embodiment modification, the washer fluid L is distributed at two locations via two connectors 15. This first non-limiting embodiment modification allows the washer fluid L to be well dispersed in the windshield wiper 1.
[0078] According to a second non-limiting embodiment shown in Figure 10, the supply pipe 170 is directly connected to a single connector 15. In other words, the windshield wiper 1 does not have an intermediate transport pipe 18 for the washer fluid L. In this example, the single connector 15 delivers the washer fluid L to the air deflector 14, i.e. Hydraulic pressureThe supply is distributed directly to the manifold 16a. As shown in the non-limiting example in Figure 11, the supply pipe 170 is directly connected to the first connector 15, which is the lower connector 15 in this example.
[0079] Similar to the first non-limiting embodiment variation, in one non-limiting embodiment, Hydraulic pressure The manifold 16a is equipped with spray orifices 160 in two of its parts, namely the lower part 16a.1 and the upper part 16a.3.
[0080] In this example, the single connector 15 which is the lower connector 15 is at least one of the Hydraulic pressure For supplying washer fluid L to at least one portion 16.1 of manifold 16a Hydraulic pressure It features channel 15.1.
[0081] Therefore, as shown in Figure 11, the lower connector 15 receives the washer fluid L. Hydraulic pressure The manifold 16a is configured to transport to the lower portion 16a.1, the central portion 16a.2, and the upper portion 16a.3. Therefore, the lower connector 15 has two Hydraulic pressure It has channel 15.1. That is, - Hydraulic pressure Connect to the lower part 16.1 of manifold 16a. Hydraulic pressure Channel 15.1, configured to transport washer fluid L to its lower portion 16a.1 Hydraulic pressure Channel 15.1 and, - Hydraulic pressure Another connection to the central part 16a.2 of manifold 16a Hydraulic pressure Channel 15.1, Hydraulic pressure The manifold 16a is configured to supply washer fluid L to the central portion 16.2 and the upper portion 16a.3. Hydraulic pressure Channel 15.1 and, It is equipped with.
[0082] In this example, it should be noted that a pump (not shown) with sufficient power is required to transport the washer fluid L to the upper section 16a.3. Such a pump is located under the hood of the automobile 2 and is connected to the tank.
[0083] In one non-limiting embodiment, the lower connector 15 further comprises a cannula 15.2 configured to connect directly to a supply pipe 170.
[0084] Figure 12 shows the second connector 15, which is referred to as the upper connector. The upper connector 15 is Hydraulic pressure Two connections to the central part 16a.2 and the upper part 16a.3 of the manifold 16a, respectively Hydraulic pressure It has channel 15.1. Hydraulic pressure Channel 15.1 carries the washer fluid L, which has been transported to the central portion 16a.2 via the lower connector 15. Hydraulic pressure It is configured to send the washer fluid L from the central part 16a.2 of the manifold 16a to the upper part 16a.3. Therefore, the washer fluid L is Hydraulic pressure From one part of manifold 16a to another part, Hydraulic pressure It is delivered via channel 15.1. Specifically, the washer fluid L is delivered from the central section 16a.2 to the upper section 16a.3, through the two upper connectors 15. Hydraulic pressure It is sent via channel 15.1.
[0085] In one non-limiting embodiment, the upper connector 15 does not have an inlet for the washer fluid L. For this purpose, in one non-limiting embodiment modification, the upper connector 15 further comprises a cannula 15.2 configured to be closed by a plug 15.4. This prevents the washer fluid L from leaking to the outside and allows the use of the same standard components for the lower connector 15 and the upper connector 15.
[0086] Therefore, according to a second non-limiting embodiment modification, the washer fluid L is distributed at a single location, via one of the two connectors 15, in this example, the lower connector 15. Naturally, in another non-limiting embodiment, the washer fluid L Hydraulic pressure The upper connector 15 may be used to transport the fluid between the central portion 16.1 and the upper portion 16.3 of the manifold 16a. In this case, the supply pipe 170 is directly connected to this upper connector 15.
[0087] According to a second non-limiting embodiment, the central mounting unit 13 is responsible for all or part of the function of spraying the washer fluid L onto the glass surface 20. For this purpose, according to this second non-limiting embodiment shown in Figures 13 to 28, the distribution device 17 comprises a supply pipe 170 connected to the central mounting unit 13, and the central mounting unit 13 comprises all or part of the spray device 16. As shown in the bottom view of Figure 14 and the enlarged view of Figure 15, and the enlarged views of Figures 21 and 27, the supply pipe 170 is connected to the central mounting unit 13 via a cannula 13.1.
[0088] According to the first non-limiting embodiment modification shown in Figures 13 to 17, the central mounting section 13 is responsible for all of the spraying function. For this purpose, the central mounting section 13 comprises the entire spraying device 160. Thus, as shown in Figures 16 and 17, the central mounting section 13 comprises at least one spraying orifice 16 Hydraulic pressure The manifold 16a is provided. For simplicity, only a portion of the spray orifice 160 is given a reference numeral in Figures 16 and 17. As shown in Figure 17, in one non-limiting embodiment, at least one of the above Hydraulic pressure The manifold 16a is equipped with a spray orifice 16 along its entire length. This allows the washer fluid L to be sprayed. Hydraulic pressure Spray can be applied along the entire length of the manifold 16a, through all of its parts 16.1, 16.2, and 16.3.
[0089] As shown in Figures 18 and 19, the air deflector 14 does not have a spray orifice 160 in its lower component 14.1 (shown in Figure 18), its central component 14.2 (shown in Figure 18), or its upper component 14.3 (shown in Figure 19). Therefore, it does not perform a spraying function.
[0090] According to the second non-limiting embodiment modification shown in Figures 20 to 28, the central mounting portion 13 performs part of the spraying function, and the air deflector 14 performs part of the spraying function. Therefore, the central mounting portion 13 comprises part of the spraying device 16, and the air deflector 14 comprises part of the spraying device 16. The spraying device 16 comprises at least one main forming part of the central mounting portion 13. Hydraulic pressure Manifold 16a and at least one sub-part forming part of the air deflector 14 Hydraulic pressure It is equipped with manifold 16b.

Therefore, a single manifold central mounting section 13 and a single manifold air deflector 14 are present.
[0092] In a second non-limiting embodiment, not shown, of this second non-limiting embodiment, the spraying device 16 comprises two main manifolds 16a and two sub Hydraulic pressure The manifold 16b is equipped with a supply pipe 170 that carries washer fluid L to two sub-air deflectors 14. Hydraulic pressureThe manifold 16b is connected to a central mounting section 13 configured to transport via two connectors 15. Thus, there is a central mounting section 13, which is referred to as a double manifold central mounting section. Similarly, there is an air deflector 14, which is referred to as a double manifold air deflector. This can improve the cleaning of the glass surface 20. Hydraulic pressure The manifold 16a extends along each side of the central mounting section 13, and has two sub Hydraulic pressure The manifold 16b extends along each side of the air deflector 14.
[0093] In one non-limiting embodiment, two main Hydraulic pressure The manifold 16a operates alternately in response to the movement of the windshield wiper 1. This shortens the cleaning time for the glass surface 20 and improves the cleaning effect by spraying more washer fluid L. Operation refers to the main operation. Hydraulic pressure This means that the manifold 16a sprays the washer fluid L onto the glass surface 20. When deactivated, the washer fluid L is not sprayed. Therefore, when the windshield wiper 1 is moving upward, one main Hydraulic pressure When manifold 16a is operating and the windshield wiper 1 is moving downward, the other main Hydraulic pressure Manifold 16a is activated. Hydraulic pressure The same applies to manifold 16b. In one non-limiting embodiment, two sub Hydraulic pressure The manifold 16b operates alternately in response to the movement of the windshield wiper 1. This reduces the cleaning time of the glass surface 20. Operation refers to the sub-operation. Hydraulic pressure This means that the manifold 16b sprays the washer fluid L onto the glass surface 20. When deactivated, the washer fluid L is not sprayed. Therefore, when the windshield wiper 1 is moving upward, one of the sub-wipers Hydraulic pressure When manifold 16b is operating and the windshield wiper 1 is moving downward, the other auxiliary Hydraulic pressure Manifold 16b is activated.
[0094] The single manifold central mounting section and the single manifold air deflector 14 are given as non-limiting examples in the following description.
[0095] Furthermore, as shown in Figures 21 and 22, the distribution device 17 also includes a transport pipe 171. The transport pipe 171 is connected to the central mounting section 13 and also to at least one of the two connectors 15. In the non-limiting examples shown in Figures 21 to 24, this connector 15 is the lower connector 15. Therefore, the washer fluid L is supplied to the auxiliary Hydraulic pressure In the manifold 16b, the fluid is distributed by the lower connector 15. Therefore, the central mounting section 13 distributes the washer fluid L to the lower part of the air deflector 14. Hydraulic pressure The material is transported to the manifold 16b via the lower connector 15.

Thus, an air deflector 14, referred to as a single manifold air deflector, is present.
[0102] Therefore, as shown in Figure 25, the air deflector 14 is a secondary part, also referred to as the lower part 16b.1. Hydraulic pressureIt comprises the first part of the manifold 16b.

As shown in Figure 26, the upper portion 16b.3 includes a spray orifice 160 extending from the upper end of the windshield wiper 1 to the upper connector 15. Thus, the upper portion 16b.3 is part of the upper component 14.3 of the air deflector 14. Therefore, the lower portion 16b.1 allows the washer fluid L in the lower component of the windshield wiper 1 to be sprayed, and the upper portion 16b.3 allows the washer fluid L in the upper component of the windshield wiper 1 to be sprayed.

As shown in Figure 33, the upper portion 16a.3 comprises a spray orifice 160 extending from the upper end 1.2 of the windshield wiper 1 to the upper connector 15.

For this reason, in another non-limiting embodiment, the reinforcing member 11 comprises three berdibras having three connectors integrally connected by the intermediate mounting section.
