Description

Description Title of the invention: Windshield wiper blade Technical field of the invention

[0001] The present invention relates to a windshield wiper blade for a device for wiping a glass surface of a motor vehicle. Technical background

[0002] A type of windshield wiper known as a flat blade is a well-known technology. It consists of a wiping blade, usually made of elastomer, held in place along its entire length. The flat blade incorporates a longitudinal vertebra (or two parallel longitudinal vertebrae) which, among other things, stiffens the wiping blade, thus facilitating its contact with the vehicle's glass surface. Furthermore, this longitudinal vertebra is curved, and this curvature gives the wiping blade a curved shape while keeping it pressed against the glass surface.

[0003] The windshield wiper is typically attached to an arm that is driven by a motor in a back-and-forth angular motion. The wiper blade is designed to wipe the vehicle's windshield by scraping it during these back-and-forth angular movements, thereby clearing water away from the driver's field of vision.

[0004] In certain cases, particularly with long wiper blades and / or irregularly curved glass surfaces, it may be necessary to use two or three stiffening vertebrae placed end-to-end along the blade's length. Two connectors, spaced apart, are attached to at least one of each stiffening vertebra, and a central mount is hinged to each connector. This wiper blade structure allows for better distribution of forces along the blade and / or improved conformity to the curvature of the glass surface.

[0005] However, since the longitudinal ends of the vertebrae placed end to end are spaced apart in the longitudinal support of the broom, the gap thus created between the vertebrae can form a discontinuity in the distribution of forces as well as an area of ​​mechanical weakness. Summary of the invention

[0006] The present invention aims to remedy at least partially the above-mentioned drawbacks.

[0007] To this end, the invention relates to a windshield wiper blade for a vehicle's glass surface wiping device, intended to be driven by a wiper arm of the wiping device, the wiper blade comprising: - a first and a second vertebra placed end to end at their longitudinal ends, - a first and a second connector, each mounted on at least one of the first and second vertebrae, - a mount articulated at the two connectors and intended to be connected to the wiper arm, characterized in that the longitudinal ends of the first and second vertebrae opposite each other are assembled by a mobile linkage having mobility according to at least one degree of freedom, the mobile linkage being made either by complementary shapes of the longitudinal ends, or by an elastic linkage member of the wiper blade connecting the longitudinal ends together.

[0008] The movable linkage improves the wiper blade's mechanical strength by ensuring continuous load distribution along its length and creating a seamless connection in the longitudinal support at the vertebral interface, while maintaining a flexible connection without creating static tension. This enhances mechanical robustness and load distribution, particularly for longer wiper blades. Furthermore, it facilitates following the pronounced curves of certain glass surfaces, especially during wiping or when stationary, without lifting the blades from the glass.

[0009] The windshield wiper blade may also include one or more of the features described below, taken alone or in combination.

[0010] According to one embodiment, the first and second vertebrae are fixed in a respective connector positioned at the center of each vertebra, the movable link being positioned in the middle of the wiper blade.

[0011] According to another embodiment, the mobile link is positioned in the first connector, the first vertebra being fixed in the first connector, the second vertebra being able to slide in the longitudinal support and the first connector and the second vertebra being fixed in the second connector.

[0012] According to another embodiment, the windshield wiper blade has a third vertebra, the second and third vertebrae being joined end to end by their longitudinal ends, the longitudinal ends of the opposing second and third vertebrae being joined by a movable joint exhibiting mobility along at least one degree of freedom, the movable joint being achieved either by shapes complementary to the longitudinal ends, either by an elastic linking element of the wiper blade connecting the longitudinal ends together.

[0013] It can be foreseen that the first connector is mounted on the mobile link between the first and second vertebrae, that the second connector is mounted on the mobile link between the second and third vertebrae, the first vertebra being fixed in the first connector, the second vertebra being fixed in the first or second connector, the third vertebra being fixed in the second connector.

[0014] According to one embodiment, the opposing longitudinal ends have respective tongues extending parallel to each other, each tongue forming a stop for the other in the transverse direction.

[0015] According to one embodiment, the ends of the tabs are bent towards each other in the transverse direction, each bent end forming a retaining element in the longitudinal direction for the other tab.

[0016] According to one example of implementation, one of the longitudinal ends is assembled in a notch complementary to the other by a shape that gradually widens.

[0017] According to one embodiment, the elastic connecting member has longitudinal ends that assemble in a complementary notch formed in a respective longitudinal end by a widening shape.

[0018] According to one embodiment, the wiper blade includes a deflector made in one piece extending along the vertebrae, with at least two notches provided in the deflector to free the deflector from said vertebrae at the connectors and allow the connectors to be connected to the vertebrae.

[0032] In these figures, identical elements bear the same reference numbers. Detailed description

[0033] The following embodiments are examples. Although the description refers to one or more embodiments, this does not necessarily mean that each reference relates to the same embodiment, or that the features apply only to a single embodiment. Simple features of different embodiments can also be combined or interchanged to provide other embodiments without departing from the scope of the invention as defined by the claims.

[0034] In the description, the longitudinal direction L corresponds to the main axis of the wiper blade 1, along which it extends. The transverse (or lateral) direction T intersects the longitudinal direction L perpendicularly. The vertical direction V is perpendicular to both the longitudinal direction L and the transverse direction T. The lower orientation corresponds to the side of the wiper blade in the vertical direction V, as opposed to the upper orientation.

[0035] Figure 1 represents a wiping device 100 allowing the wiping of a glazed surface of a motor vehicle, such as the windshield.

[0036] The wiping device 100 comprises at least one wiper blade 1 and at least one wiper arm 200 designed to pivot a respective wiper blade 1 to sweep the glass surface in a series of back-and-forth cycles. The wiper blade 1 is specifically configured to sweep a glass surface with significant variations in curvature or with a large dimension, such as the windshield of heavy goods vehicles or buses, or a panoramic glass surface. The wiper blade 1, for example, has a dimension greater than 1 meter in the longitudinal direction L.

[0037] The wiper blade 1 is of the FlatBIade ® type (flat blade). It has a wiping blade 2 made of a flexible material suitable for contacting the glass surface to be wiped.

[0038] The windshield wiper blade 1 may include a deflector 3 (forming what is called a "spoiler") extending along the blade and aerodynamically shaped so that the relative wind produced by the vehicle's movement exerts a force tending to press the wiper blade 1 against the glass surface. One or more channels may be provided in the deflector to convey a washing fluid for projection onto a glass surface of the vehicle. The channel may open laterally from the deflector 3 through at least one projection orifice. The projection orifices may, for example, be regularly distributed along the longitudinal axis, thus forming a spray ramp longitudinally along at least one side of the deflector 3, allowing the washing fluid to be distributed onto the glass surface.

[0039] End caps 5 (called "endclip" in English) can be fitted to each end of the brush 1.

[0040] As more clearly seen in Figure 2, the broom 1 also includes at least one first and second longitudinal vertebrae 6, 7 (called "spline" in English) joined end to end by their longitudinal ends and which form the structure of the broom 1 proper.

[0041] Vertebrae 6 and 7, for example, are arranged in a longitudinal support 4 of the broom (called a "holder" in English). The support 4 of the broom 1 can also be used to hold the wiping blade 2.

[0042] Each vertebra 6, 7 is formed from a single body, comprising for example a flat metal strip which is curved vertically, so that when the wiper blade 1 is in contact with the glass surface, the support forces exerted by the wiper arm 200 are distributed over the entire length of the wiper blade 2.

[0043] The wiper blade 1 also has two connectors 8, 9, spaced apart, each mounted on one or two vertebrae 6, 7, for example by edges of the connector 8, 9 enclosing the sides of a respective vertebra 6, 7.

[0044] Connectors 8 and 9 are each articulated to a mount 10 of the brush 1, for example, by a pivot joint around a transverse axis T. The mount 10 is itself- even mechanically connected to the wiper arm 200, for example via an adapter 210 of the arm 200, for mounting and articulation of the wiper blade 1 to the wiper arm 200 (figure 1).

[0045] The pressure force exerted by the arm 200 connected to the mount 10 is distributed over the two connectors 8, 9 and then along the wiping blade 2 via the connectors 8, 9 and the vertebrae 6, 7.

[0046] The longitudinal ends of vertebrae 6, 7 opposite each other are joined by a movable connection (or partial connection or flexible connection) exhibiting mobility along at least one degree of freedom, as opposed to a complete (or total) connection for which there is no possibility of movement between the assembled parts.

[0047] The mobile connection is achieved either by complementary shapes of the ends of vertebrae 6, 7, i.e. by a direct connection (figures 2 to 5), or by an elastic connecting element 11 of the wiper blade 1 linking the two longitudinal ends together, i.e. by an indirect connection (figures 6 and 7).

[0048] The movable linkage improves the mechanical strength of the wiper blade 1 by ensuring continuous load distribution along its length and creating a seamless connection in the longitudinal support 4 at the interface of vertebrae 6 and 7, while maintaining a flexible connection, i.e., without generating isostatic forces. This enhances mechanical robustness and load distribution, particularly for longer wiper blades. Furthermore, it is easier to follow the pronounced curves of certain glass surfaces, especially during wiping or when stationary, without lifting the wipers from the glass surface.

[0049] In the first illustrative example, the broom 1 comprises two vertebrae 6, 7, each vertebra 6, 7 being fixed in a respective connector 8, 9. The vertebrae 6, 7 are, for example, press-fitted into grooves of a respective connector 8, 9. The vertebrae 6, 7 can also be assembled by elastic clipping, that is, by slightly opening the connector 8, 9 and releasing it once the vertebra 6, 7 is positioned. Additional retaining forms 18 of the connector 8, 9 and vertebra 6, 7 can ensure a lock of vertebra 6, 7 as will be seen later in relation to figure 9. According to another example, vertebra 6, 7 can be assembled with a play in the connector 8, 9 then a deformation of the material of the connector 8, 9 in notches of vertebra 6, 7 can immobilize the latter.

[0050] The two vertebrae 6 and 7 are, for example, of the same length. Each connector 8 and 9 is, for example, positioned at the center of each vertebra 6 and 7. The movable link is positioned in the middle of the brush 1.

[0051] Figures 2 and 3 show a first example of the realization of a mobile link between the longitudinal ends of the first and second vertebrae 6, 7 made by complementary shapes of the longitudinal ends (direct link) (without additional linking element).

[0052] In this embodiment, the longitudinal ends of the opposing vertebrae 6 and 7 have respective tabs 12 extending parallel to each other in the longitudinal direction L, each tab 12 acting as a stop for the other in the transverse direction T (perpendicular to the longitudinal direction L). A longitudinal gap is provided in the longitudinal direction L between the tabs 12, notably to allow the vertebrae 6 and 7 to conform to the shape of the longitudinal support 4.

[0053] The movable link here exhibits one degree of freedom in the longitudinal direction L.

[0054] Figure 4 illustrates an alternative embodiment in which the ends of the tabs 12 are curved towards each other in the transverse direction T. Each curved end forms a retaining element in the longitudinal direction L for the other vertebra. Longitudinal clearance is provided in the longitudinal direction L between the tabs 12, notably to allow the vertebrae 6 and 7 to conform to the shape of the longitudinal support 4.

[0055] The movable link here exhibits one degree of freedom in the longitudinal direction L.

[0056] In this example, the displacement stroke of vertebrae 6, 7 in the longitudinal direction L is limited due to the stops formed by the curved ends and the curvature of vertebrae 6, 7. This variant provides better longitudinal mechanical stability and greater robustness of the broom 1.

[0057] Figure 5 shows another variant of the realization of a mobile connection made by complementary shapes of the ends of vertebrae 6, 7 (direct connection).

[0058] In this embodiment example, one 13 of the longitudinal ends is assembled in a notch complementary to the other 14 by a widening shape, each longitudinal end limiting the relative movement of the two vertebrae 6, 7 in the transverse direction T and / or longitudinal direction L and / or vertical direction V.

[0059] Any type of shape allowing interpenetration of the longitudinal ends is possible. Here, a longitudinal end 13 of a vertebra 7 has a rod-like shape connected to a disc which fits into a cavity complementary to the longitudinal end 14 of the other vertebra 6.

[0060] A longitudinal and transverse gap is provided between the longitudinal ends 13, 14 so as to allow the vertebrae 6, 7 to take shape in the longitudinal support 4.

[0061] This variant provides better longitudinal and lateral mechanical strength and improved robustness of brush 1.

[0062] These forms of direct mobile linkage implementation, without additional elements, make it possible to improve the mechanical behavior of the broom 1 by limiting the lateral and / or longitudinal and / or vertical movement between the two vertebrae 6, 7.

[0063] Figures 6 and 7 show a second example of a movable joint achieved by an elastic connecting element 11 of the wiper blade 1, linking the two ends together (indirect connection). The elasticity of the elastic connecting element 11 can be obtained due to the elastic properties of the material of the elastic connecting element 11. The material can be an elastomer, a rubber, a polyurethane, a silicone, or an equivalent material. This elasticity can be obtained or enhanced by a suitable geometry of the elastic connecting element 11, such as a spring-like, accordion-like, or evolving shape.

[0064] In this case, there is no play between the longitudinal ends of vertebrae 6, 7. The elastic linkage organ 11 allows to limit the relative movement of the two vertebrae 6, 7 in the transverse direction T and / or longitudinal direction L and / or vertical direction V.

[0065] The elastic connecting organ 11 is for example clipped into a complementary notch provided in each longitudinal end 14 of the vertebrae 6, 7.

[0066] In this embodiment, the longitudinal ends of the elastic connecting element 11 fit into a complementary notch formed in a longitudinal end 14 of a respective vertebra 6, 7 by a progressively widening shape. Any shape allowing interpenetration of the elastic connecting element 11 and the longitudinal ends 14 of vertebrae 6, 7 is possible. Here, the elastic connecting element 11 has a rod-like shape whose ends are connected to a respective disc, the elastic connecting element 11 fitting into complementary cavities in the longitudinal ends 14 of vertebrae 6, 7.

[0067] During assembly, vertebrae 6 and 7 can first be attached to the elastic connecting member 11, and then the assembly can be slid into the longitudinal support 4. Alternatively, the elastic connecting member 11 can be attached to the longitudinal ends 14 of vertebrae 6 and 7 through the upper opening of the longitudinal support 4 after vertebrae 6 and 7 have been mounted in the support. longitudinal 4 (see mounting arrows of the elastic linking member 11 in the vertical direction V on figure 6).

[0068] Figures 8 and 9 show another example of an embodiment in which the wiper blade 1 comprises a first, second and third vertebra 15, 16, 17 joined end to end by their longitudinal ends.

[0069] The first and third vertebrae 15, 17, located at the longitudinal ends of the wiper blade 1, for example, have shapes optimized for following the local curvature of the glass surface at the end of the blade 1, in particular a suitable cross-section or cutout. The second vertebra 16, interposed between the first and third vertebrae 15, 17, ensures the continuity of the wiper blade 1 and good pressure distribution along its length. The three vertebrae 15, 16, 17 can be pre-assembled together before being slid into the longitudinal support 4.

[0070] The longitudinal ends of the second and third vertebrae 16, 17 opposite each other are joined by a mobile connection made either by complementary shapes of the longitudinal ends, or by an elastic connecting element 11 of the wiper blade 1 linking the longitudinal ends together.

[0071] The second vertebra 16 is not fixed in both connectors 8, 9 but left free in one of the two connectors 8, 9 in order to avoid the isostaticity of the broom 1.

[0072] According to one embodiment, the first connector 8 is mounted on the first and second vertebrae 15, 16 at the movable link between the vertebrae 15, 16. The first vertebra 15 is fixed in the first connector 8, the second vertebra 16 is fixed in the first or second connector 8, 9.

[0073] The second connector 9 is mounted on the second and third vertebrae 16, 17 at the level of the mobile link between vertebrae 16, 17. The third vertebra 16 is fixed in the second connector 9.

[0074] The mobile connection is for example achieved by complementary shapes of the longitudinal ends of vertebrae 15, 16 opposite each other (direct connection).

[0075] An example of the realization of the mobile link between the first and second vertebrae 15, 16 at the level of the first connector 8 is shown schematically in figure 9, the longitudinal ends of the vertebrae 15, 16 having tabs 12 as described in the two-vertebrae embodiment 6, 7.

[0076] The first vertebra 15 is fixed to the first connector 8, for example, by means of additional retaining forms 18 formed in the flanks of the first vertebra 15 and the edges of the first connector 8. In the illustrative example, the edges opposite the first connector 8 have bulges rounded extending into complementary notches made in the sides of the first vertebra 15.

[0077] With the first vertebra 15 fixed in the first connector 8, the mobile link here presents a degree of freedom of movement of the second vertebra 16 which can slide in the longitudinal support 4 and the first connector 8 in the longitudinal direction L (see double arrow on figure 9).

[0078] The other characteristics of this example implementation are similar to those of the first example implementation.

[0079] Figure 10 illustrates an alternative embodiment in which the ends of the tabs 12 are bent towards each other in the transverse direction T as described in the two-vertebrae embodiment 6, 7.

[0080] The mobile link here presents a degree of freedom of movement of the second vertebra 16 which can slide in the longitudinal support 4 and the first connector 8 in the longitudinal direction L (see double arrow on figure 10).

[0081] The other characteristics of this example implementation are similar to those of the previous example implementation.

[0082] The mobile connection between the first and second vertebrae 15, 16 at the level of the first connector 8 can also be achieved by assembling one 13 of the longitudinal ends in a notch complementary to the other 14 by a widening shape or by an indirect mobile connection made by an elastic connecting member 11 of the wiper blade 1 connecting the two ends together.

[0083] The mobile link between the second and third vertebrae 16, 17 at the level of the second connector 9 can correspond to one or the other of the realizations described for the mobile link between the first and second vertebrae 15, 16 at the level of the first connector 8.

[0084] It is therefore possible to improve the design of the first and third vertebrae 15, 17 at the ends of the broom 1 without impacting the distribution of forces at the center of the broom 1 ensured by the central second vertebra 16 and without impacting the mechanical robustness of the broom 1.

[0085] Figure 11 shows another embodiment in which the wiper blade 1 comprises a first and second vertebra 15, 18 joined end to end by their longitudinal ends. The movable linkage is positioned in the first connector 8, the first vertebra 15 being fixed in the first connector 8, the second vertebra 18 being able to slide in the longitudinal support 4 and the first connector 8. The second vertebra 18 is fixed in the second connector

[0086] The mobile link in the first connector 8 between the longitudinal ends of the first and second vertebrae 15, 18 can be either of the realizations described for the mobile link between the first and second vertebrae 15, 16 at the level of the first connector 8.

[0087] Figure 12 shows another example of the deflector 30. This deflector 30 can be assembled on the wiper blades 1 previously described with two or three vertebrae placed end to end.

[0088] In this embodiment example, the deflector 30 is made in one piece extending along both 6, 7; 15, 16; 15, 18 or three vertebrae 15, 16, 17.

[0089] The deflector 30 made in one piece means that it forms a unit piece but which can be obtained from the assembly of different parts, such as hooks and a fin, for example by coextrusion, overmolding or bonding.

[0090] At least two notches 30a, 30b are provided in the deflector 30 to free the deflector 30 from the vertebrae at the connectors 8, 9 and allow the connection of the connectors 8, 9 to the vertebrae.

[0091] According to one embodiment, at least one channel 31, through which a washing fluid is intended to circulate, is provided in the deflector 30. This channel 31 extends along a longitudinal axis of the deflector 30 and opens laterally from the deflector 30 through a plurality of spray orifices. The channel 31 is intended to be supplied with washing fluid at one end of the deflector 30 via an end fitting 5 of the wiper blade 1. The other end fitting 5 has a plug that seals the channel 31 of the deflector 30 at the end of the channel 31. In this way, there is no longer a need for inlet and outlet nozzles, nor for an internal conduit in the connectors 8, 9, nor for the need for sealing inserts required for the internal conduit, thus reducing costs.

[0092] According to one embodiment, channel 31 is offset to one side of the fin. The outer contours of deflector 30 are then asymmetrical. The tip of the fin, for example, is offset laterally on the same side of brush 1 as channel 31. Channel 31 thus extends along the longitudinal axis of brush 1, without interruption by connectors 8 and 9, because it is offset laterally beyond connectors 8 and 9. This embodiment has the advantage that the continuity of drilling the projection holes during manufacturing is facilitated because it is no longer hindered by connectors 8 and 9 when drilling is carried out after assembly of deflector 30, and this without the need for a lateral window in connector 8 and 9. Furthermore, the orientation of the projection holes can be chosen more freely. optimize washing. Also, the projection can be carried out continuously along the entire length of the broom 1, including in the area of ​​the connectors 8, 9.
