Description

Field of the Invention The present invention relates to a vehicle windscreen wiper device, in particular a motor vehicle, comprising a windscreen wiper blade having: an elongate at least partially flexible upper part, an elongated lower part at least partially flexible, several connecting elements connecting the upper part and the lower part being distributed in the direction of longitudinal extension of the wiper device, * the connecting elements allowing the relative movement of the upper part and the part lower relative to one another with a movement component in the direction of longitudinal extension of the wiper device, a fixing device, wiper blade side, to achieve a detachable connection with a fastening element on the side of the vehicle. State of the art The wiper devices comprise an ice-wiper arm or a wiper lever for driving the wiper blade cleaning the window of the vehicle. The wiper blade is moved between a first and a second reversing position. For this, the wiper arm is connected to the drive shaft of the wiper motor. In particular, in the case of motor vehicle windows having large variations in curvature, the wiper blade easily loses contact with the window. This can result in unsworn beaches or the development of trails or traces on strongly curved windows. As window cleaning must be optimized taking into account a large number of parameters such as the amount of rain arriving on the glass, a possible snow load on the glass or the development of frost, we can not avoid the development of sails or trails simply by adjusting the pressure of the wiper arm exerted on the windshield. Curved panes or windshields may be better wiped, for example in the case of wipers of "Fin-Ray" type, because thanks to the movable connecting elements of such a windscreen wiper blade allowing relative movement. between the upper and the lower part of the wiper blade, the adaptation to the curvature of the windshield will be improved. In addition, since it is necessary to manually remove dirt cluttering another window or rearview mirror of the vehicle, there are a large number of utensils for cleaning the windows, including those of motor vehicles, for example to clean windows or windshields, to clear snow, ice or other obstructions on the windows. OBJECT OF THE INVENTION The object of the present invention is to improve window cleaning devices and to develop a means of reliably wiping, virtually without streaks or sails, a vehicle window and can also be used for manual cleaning of the glass.

DESCRIPTION AND ADVANTAGES OF THE INVENTION For this purpose, the subject of the invention is a windscreen wiper device of the type defined above, characterized in that the wiper blade comprises in addition to a lip of wiping, a first cleaning device for cleaning the glass.

In other words, the subject of the invention is a vehicle wiper device, in particular a motor vehicle. The wiper device comprises a wiper blade consisting of an elongated upper portion and an elongated lower portion, both of which portions are at least partially flexible. A plurality of connecting members connect the upper and lower portions by being distributed in the direction of longitudinal extension of the wiper blade. The connecting members allow relative movement of the upper and lower portions with a movement component in the longitudinal extension direction of the wiper blade.

The wiper device further comprises a fixing device, wiper blade side, for making a detachable connection with a connecting element, vehicle side. The wiper blade also includes a wiping lip forming part of a first cleaning device for cleaning windows, including those of motor vehicles.

The invention also relates to the use of a wiper device as defined above for manually cleaning a window. According to the embodiments of the invention, the vehicle windscreen wiper device makes it possible to use it in multiple application areas in a particularly advantageous manner. The wiper device according to the invention, in particular with a wiper blade of "Fin-Ray" type, removable, comprises in addition to the wiping wiper lip, a cleaning device for cleaning windows. This results in a wiper device for many applications. In particular, there is a wiper device which is simple and practical to use and which offers the user one or more additional cleaning functions, in particular the manual cleaning of windows.

According to another development, the invention relates to a wiper device for cleaning a window to remove dirt, ice, snow, glass. In particular, the developments described hereinafter of a wiper device have the cleaning function of the special cleaning devices made for certain specific applications such as those of broom sponges or ice cream scrapers. The wiper device with the additional cleaning function allowing manual operation of the windscreen wiper device, that is to say use beyond its application to the vehicle, can be used to clean the wiper blade. inside the vehicle to remove residual moisture deposits or dirt on the manually operated wiper device. In contrast, the usual special tools, such as sponges, brushes or ice scrapers, which are stored inside the vehicle can also dirty the interior of the cabin. According to the embodiments described, the wiper device has multiple applications; it is multifunctional and easy to use. The first cleaning device is on the elongated upper part extending substantially in the direction of longitudinal extension of the wiper device, which allows a particularly efficient manual cleaning of a window.

The first cleaning device comprises a material capable of absorbing or sucking and in particular a sponge. This thus makes it possible to have cleaning water thanks to this absorbent material for use on the surface to be cleaned such as, for example, a window to remove the dried dirt soluble in water. The first cleaning device comprises brushes so that one has a cleaning device with a function of a brush or brush for the manual cleaning of the windows. The first cleaning device includes a scraping device or claws for removing ice. There is thus a wiper device with an ice scraper function for the manual cleaning of the windows. The scribing or scraping device is provided on the edge of the elongate upper part and / or on the edge of the elongated lower part, which substantially corresponds to the longitudinal extension of the wiper device, which gives a particularly effective ice squeegee function. The scraper device comprises a scraping bar and / or a plurality of scraping elements, in particular claws, which gives a wiper device that offers one or more scraping functions that are different and that can be used depending on the degree of deposition of ice or of frost. A second cleaning device equips the end of the wiper blade away from that for attachment and is substantially transverse to the first cleaning device. There is thus another cleaning device particularly suitable for cleaning small surfaces such as exterior mirrors. The windscreen wiper device has an ergonomically shaped head piece for end gripping provided with the attachment device, resulting in a simple and easy-to-operate wiper device for manual window cleaning. The head piece has an actuating device for releasing a force and / or shape connection between the fastening device and the connecting element, which corresponds to a removable ice-resealing device. a particularly simple way.

A standard adapter connects the fastener to the link member, resulting in a windscreen wiper device that can be connected to different link members on the vehicle side. The connecting elements are hingedly connected to the lower part and / or the upper part. In particular, the connecting elements are connected to the lower part and / or to the upper part by a first hinge film. This first film-hinge can be in one piece with the connecting element and with the upper part and / or the lower part. This one-piece production of the hinge film corresponds to a simple and economical manufacture. It is thus possible to produce wiper blades or wiper devices by a suitable design giving a product that can be used directly at the outlet of the mold. In addition, the use of hinge films, in particular by the one-piece production of the hinge-film with the connecting elements and the upper part and / or the lower part, allows manufacturing by an injection method. The width of the lower part and / or that of the upper part in the direction of longitudinal extension of the wiper blade decreases towards the end of the wiper blade, in particular by a continuous decrease. There is thus a wiper device whose moment of inertia decreases toward the end of the wiper blade. In addition, there will be a very regular application pressure of the wiper device against the window and also a uniform distribution of the forces of the wiper device, which allows better adaptation to the window and as result, a very high quality of wiping and cleaning.

DESCRIPTION OF EMBODIMENTS OF THE INVENTION FIG. 1 shows a wiper blade 2 of a windscreen wiper device according to the invention, in particular a wiper device of the type "Finish Ray ". The wiper blade is comprised of an elongated upper portion 10 and an elongate lower portion 12. The upper portion 10 and the lower portion 12 are at least partially flexible. The upper part 10 and the lower part 12 are connected by connecting elements 18 distributed in the direction of longitudinal extension of the wiper blade 2 to allow the relative movement of the upper part 10 and the lower part 12 practically. following the direction of longitudinal extension. The wiper blade 2 has a wedge shape; the upper part 10 and the lower part 12 are connected to an outer connection position 34. The upper part 10 and the lower part 12 are fixed to a head piece 70, on the wiper blade side. The head piece 70, on the wiper blade side, comprises a fixing device 77 for fixing the wiper blade to a fastening element 50 of the vehicle which is, for example, a motor vehicle. Fixing between the fixing device 77 and the connecting element 50 can be released by an actuating device 71, for example a release button, a lever, a pushbutton or other actuating device. The wiper blade 2 according to the described embodiments is detachably connected by the fixing device 77 and the connecting element 50. Thus, to clean a window by hand, the broom can be easily removed. of wiper and use it as a cleaning device (see for example Figures 2, 3, 4, 5a, 5b and / or 5c).

The head piece 70, on the wiper blade side, comprises an actuating device 71 for releasing the connection by force and / or by the form between the fixing device 77 and the connecting element 50, on the vehicle side . Typically, the head piece 70, wiper blade side, has an ergonomic shape to facilitate gripping. The actuating device 71 is a push button or a snap. The user can thus push the actuating device 71 to release the connection by force and / or shape and disassemble the wiper device, that is to say remove it from the element of link 50. The wiper device can thus be replaced or removed simply and then be installed again just as easily. The connecting element 50 is designed as an interface for transmitting the torque to the wiper arm. To connect the securing device 77 to the connecting element 50, a standard adapter 60 is used. The standard adapter 60 is typically designed to allow the wiper device to be connected to different connecting elements on the side. vehicle. The head piece 70, wiper blade side, may include an opening for the standard adapter 60 (this opening is not shown) on the underside of the head piece. As is described, for example, in connection with FIG. 1, the ice-wiper device, particularly if it is a "Fin-Ray" wiper device, may be installed or disassembled by a fast connection in a simple way to a vehicle. A locking member, for example a retaining spring, is installed or integrally integrated in the wiper blade or the head piece 70, wiper blade side. For assembly, the wiper blade is connected axially to the connecting element 50 which is for example a bearing shaft or drive shaft. Fixing is done by a translation movement. This translational movement is indicated by an arrow in FIG. 1. For example, when the device is fitted onto the axle, a spring is discarded which then catches in a cavity of the connecting element. or the standard adapter. According to embodiments, the interface between the fixing device 77 of the head piece 70, wiper blade side, and the connecting element, on the vehicle side, makes it possible to transmit a torque. The wiper blade shown in the figures is a "Fin-Ray" wiper blade. The upper part 10 is connected to the lower part 12 by movable connecting elements 18. The connecting members allow the relative movement of the upper and lower parts relative to each other with a movement component in the direction of longitudinal extension of the wiper blade. A wiper device such as those described above uses the effect of caudal scales of some fish which, under the effect of a lateral thrust, do not escape in the direction of the thrust or pressure but take a curved shape in the opposite direction, that is to say in the direction from which the thrust originates. This principle is also called the radiated structure principle or the "Fin-Ray" principle. A wiper device according to the embodiments described above thus has the advantage of a better adaptation to the window of a vehicle. In the case of a conventional wiper blade, the upper part is usually rigid, that is to say it is not flexible. The connecting elements 18 may have different heights. The height of the connecting members 18 decreases at least in the region towards the opposite sides of the head piece 70, wiper blade side. The upper part 10 and the lower part 12 may be connected to an outer connection position 34. FIG. 2 is a perspective view of an example of a wiper blade end of a wiper device. ice according to the invention. As shown for example in Figure 4, the wiper lip 72 is typically provided on the lower portion 12 of the wiper blade 2. The wiping lip can be made of the same material as the wiper blade. 'wiper. Alternatively, the lip may be of a different material than the wiper blade. The wiping lip may be made of one or the other material of the group comprising: TPE (thermoplastic elastomer), for example TPE-S, TPE-O, TPE-U, TPE-A, TPE-V and TPE -E, ethylene-propylene-diene rubber (EPDM), polychloroprene and natural rubber.

The wiper lip 72 can be used for manual cleaning. By removing the windscreen wiper device from the vehicle-side link member 50, for example the drive shaft, the wiper device can be used to manually clean the vehicle, including windows and mirrors, to eliminate water. As the wiper device is adapted to the curvatures of the windows and mirrors, the cleaning will be particularly effective on surfaces with different bends, for example windows or mirrors. The quick-release connection can also be used for simple disassembly and assembly.

In addition, at the outer connection position 34, there may be an additional wiper lip oriented substantially transversely to the direction of the main lip. This allows manual cleaning of small areas such as side mirrors. As shown in Figure 3, the wiper device also incorporates a manual wash function. For example, an absorbent material or material 73 may be provided on the upper portion 10. The absorbent material may be provided on the connecting member of the upper portion 12 to be replaceable. In addition, the absorbent material may for example be glued to the upper part. In addition or alternatively, the absorbent material may also be provided at another location of the wiper device, for example at the outer connection position 34 or at the head portion 70, wiper blade side. ice of the windscreen wiper device. It is particularly advantageous that the absorbent material is at the outer binding position 34 to be able to clean small surfaces such as for example side mirrors. The absorbent material is, for example, a natural or synthetic sponge. Absorbent material is a material that can substantially absorb liquid and return it when the material is compressed. For example, different foams can be used. Typically, the absorbent material can be compressed sufficiently to return cleaning water when compressed. The absorbent material has a transverse contraction coefficient of between 0.05 and 0.2. Cleaning with water or cleaning water supplied to the absorbent material serves to remove tough, eg dry, dirt. This thus makes it possible to wet the dirt of a window or a mirror by using the glass device shown in FIG. 3 and to proceed with the immersion with the aid of an absorbent, impregnated material 73. The function of Manual washing according to the embodiments described above of the wiper device thus makes it easier to remove the dirt. In addition, the described embodiments of the wiper device to provide cleaning water by the absorbent material for a surface to be cleaned, for example a window, allows the removal of dried dirt and / or soluble in water. The embodiment of the wiper device as shown for example in Figure 4 comprises a first cleaning device in the form of brushes 74. The brushes 74 may have in addition or alternatively an absorbent material 73. The brushes 74 are attached to the upper part 12 by a connecting element, which allows to replace them. The brushes may be glued to the upper part 10. The brushes may also be provided at another location of the windscreen wiper device, for example at the outer linkage position 34 or at the head portion 70, the blade side of the wiper blade. the wiper of the ice-wiper device. The brushes 74 at the outer connection position 34 constitute a particularly advantageous solution for cleaning small surfaces such as for example those of side mirrors. Typically, the brushes 74 comprise fiber elements bundled together or evenly distributed. These fibers can be natural fibers or synthetic fibers such as plastic fibers. According to the embodiments described, the density of the fibers and / or the thickness of the fibers are chosen so as not to damage the windows or the mirrors. Typically, the wiper devices described herein can be used to manually remove snow and / or heavy dirt such as leaves. FIGS. 5a-5c show various embodiments of the windscreen wiper device comprising a scraper device 80. For example, as shown in FIG. 5a, the scraper device 80 is provided on the edge of the part an elongated upper 10 which extends substantially in the direction of longitudinal extension 8 of the windscreen wiper device. Alternatively or additionally, the scraper device 80 or any other claw device may be provided on the lower part of the wiper device as shown for example in Figure 5b. The scraping device may consist of a continuous scraper blade as shown in FIGS. 5a and 5b or may be composed of several scraping elements 91, in particular claws, as shown by way of example in FIG. 5c. . There is thus a windscreen wiper device which provides one or more additional scraping functions necessary, such as the degree of icing. According to the embodiments described here, the scraping claws may be provided on the edge of the elongated lower portion 12 in the direction of longitudinal extension 8 of the windscreen wiper device. The scraping device is made of materials having a hardness less than that of the surface to be cleaned so as not to damage this surface which is for example glass. The scraping device may be made of plastics such as for example weather-resistant polycarbonates or transient metals such as for example copper and / or alloys thereof. According to embodiments of the wiper device, the absorbent material 73 and / or the brushes 74 and / or the scraper device 80 of the first cleaning device are disposed substantially along the longitudinal extension of the wiper device. ice cream. The wiper device may also include a second cleaning device installed substantially across the first cleaning device. The second cleaning device may comprise an absorbent material 73 and / or a broom 74 and / or a scraper device 80. The second cleaning device is installed at the end of the wiper blade, away from the device. The cleaning devices described above can be used each time separately but also in combination with each other when installed on the windscreen wiper devices. In particular, the combination of different cleaning devices makes it possible to associate them with different positions of the windscreen wiper device. For example, they may be provided on the upper part 10, the lower part 12, the head part 70 and / or on the position or connecting piece 34 (the tip).

A wiper device will be described hereinafter by way of example using the wiping lip described above. In principle, the wiper lip can also be applied to other windscreen wiper devices. FIGS. 6A and 6B are diagrammatic representations of a wiper blade 2 in the base position (according to FIG. 6A) and in position against a window (FIG. 6B) corresponding to embodiments of the device wiper system of the invention. The wiper blade 2 is used to wipe the snow 4 of the vehicle which is for example a motor vehicle. Usually, the wiper blade 2 is provided on the wiper arm driven by a motor. The wiper blade 2 comprises a fastener 6 receiving the wiper arm. The wiper blade 2 is in FIG. 6A in its basic position in which it is at least partially raised from the window pane 4. The wiper blade 2 has a longitudinal extension 8 and comprises an upper part 10 elongate and a lower portion 12 also elongated. The longitudinal extension of the upper part 10 and the lower part 12 corresponds essentially to the longitudinal extension 8 of the wiper blade 2. The upper part 10 and the lower part 12 are flexible beams or are made as flexible beams which are each exemplified in one piece according to Figures 6A and 6B. This allows a particularly stable construction. It is also possible to make flexible only a segment of the upper part 10 and / or the lower part 12. In addition and alternatively, the upper part 10 can be made in two parts, with each time one end of the two parts of the upper part 10 fixed to the fixation 6. For the upper part 10 and / or the lower part 12, a material having a modulus of elasticity of between 0.005 kN / mm 2 and 0.5 kN / mm 2 is used, in particular between 0.01 kN / mm 2 and 0.1 kN / mm 2. There is thus adequate flexibility for the upper part 10 and the lower part 12. In combination with an appropriate sectional area of the upper part 10 and the lower part 12, there will thus be optimal flexibility. The upper part 10 and the lower part 12 are installed to face each other. The two ends of the upper part 10 are connected to the two external connection positions 14, 16, each at the end of the lower part 12 by a solid connection. For the rest, the upper part 10 and the lower part 12 are spaced apart from each other.

The upper part 10 and the lower part 12 are connected by connecting elements 18. In particular, in the basic position of the wiper blade 2, the connecting elements are oriented substantially transversely to the direction of extension. The connecting members 18 are secured by rotation joints 20 at opposite ends to the inner longitudinal side of the upper portion 10 and the lower portion 12. The joints of rotation 20 are hinges. The rotational joints 20 may in particular be made in the form of hinge films. This solution is especially advantageous if the upper part 10, the lower part 12 and / or the connecting elements 18 are made of a plastic material or are coated with a suitable plastic material. The articulation of rotation is a member selected from the following group: hinge, film-hinge, reduction of the thickness of the material to have a lower rigidity along a torsion axis, articulation with an axis of rotation, means for connecting the upper part to the connecting element and for connecting the lower part to the connecting element allowing the displacement of the lower part relative to the upper part in the direction of longitudinal extension, etc ... The embodiments for which articulation is constituted by a film-hinge thus constitute a particularly simple solution for having Fin-Ray wiper blade joints. The wiper blade 2 may be in particular made in one piece directly usable output tooling. According to typical embodiments, the hinge films have high extensibility. This results for example from the choice of material in the group PP, PE, POM and PA. Alternatively, the hinge films may be made of one or more materials of a group comprising TPE (thermoplastic elastomer), for example TPE-S, TPE-O, TPE-U, TPE-A, TPE-V and TPE-E. The connecting elements 18 are distributed along the longitudinal extension direction of the wiper blade 2. The distances between each time two adjacent connecting elements 18 are equal. But they can also be different. The differences are advantageously less than 50 mm and in particular less than 30 mm. This gives a particularly high flexibility of the windscreen wiper device, in particular of its lower part and a good adaptation to the curvature or the variations of curvature of the window to be wiped. In FIG. 6A, the distance 22 is indicated representative for the intervals between each time two connecting elements 18. The connecting elements 18, in particular in the basic position of the wiper blade 2, are fixed to the lower part 12 so that the longitudinal axis of the elements makes an angle 26 with respect to the lower portion 12 and that this angle is between 65 ° and 115 °, in particular between 75 ° and 105 °. Particularly advantageously, the angles are between 80 ° and 100 °. This results in a good transmission of the force exerted on the lower part towards the upper part. In this way, the wiper device is particularly stable. The same applies to the fastenings of the connecting elements 18 to the upper part 10. The same remarks apply to the present embodiment for the fastenings of the connecting elements 18 to the upper part 10. FIG. for example a longitudinal axis 24 for the longitudinal axis of the connecting elements 18 and an angle 26 as an example of an angle between the connecting elements 18 and the lower part 12. The differences between the upper part 10 and the part 12 depends mainly on the length of the connecting elements 18. The length of the connecting elements 18 increases from the two outer connection positions 14, 16 until substantially towards the point where the fastening 6 begins at the upper part 10 Thus the upper part 10 and the lower part 12, in side view of the wiper blade 2 of Figure 6A, are in the form of a double corner whose tips are turned in opposite directions. The connecting elements 18 are rigid when folded.

FIG. 6B schematically shows the wiper blade 2 of FIG. 6A in position applied against the window pane 4. Since the window pane 4 has a curvature, when the wiper blade 2 is applied against the window pane 4, The upper part 10 and the lower part 12 are flexible beams and the connection elements 18 are rotatably connected to the upper part 10 and to the part lower 12, these two parts 10, 12 can slide relative to each other. The thrust forces exerted from below on the upper portion 12 cause the wiper blade 2 to bend in the direction of the thrust forces so that the wiper blade applies precisely against the curvature of the wiper blade. the window 4. In the case of application of a force on the lower part (by the window 4) the construction of the embodiments described above makes it possible to produce a deflection of the lower part in the direction from which the strength. This is ensured by the connection of the upper part 10 and the lower part 12 to the connection positions 14 and / or 16, to the shape and to the rotational joints of the connection between the connecting elements and the upper part or the part lower. In Figure 6B, there is a small gap between the wiper blade 2 and the window 4 which serves here to explain the window 4 and the wiper blade 2 when in fact when the broom d 2 wiper is applied against the window 4, this interval does not exist. Also typically the lower side of the lower portion 12, not facing the upper portion 10, has a wiper lip 50 in the embodiments described herein as shown for example in Figure 1; this lip serves to wipe the window 4. For reasons of legibility of the drawing, the wiping lip of FIGS. 6A and 6B is not shown. A wiper device according to the embodiments described above uses the effect of caudal scales of certain fish which, in the event of lateral thrust, do not escape in the direction of the thrust but take a curved shape in the opposite direction, that is to say in the direction from which the thrust comes. This principle is also called the principle of radiated scales or the "Fin-Ray" principle. The wiper device according to the embodiments described above thus has the advantage of better adaptation to the window of a vehicle whereas a conventional wiper blade usually has a rigid upper portion that is to say, not flexible. Figures 6A and 6B show a wiper blade 2 with a longitudinal extension 8 substantially between the connecting positions 14 and 16. Such an arrangement is frequently used for the windshield wipers. Alternatively, a windscreen wiper device may also have only one connecting position, which, by analogy with FIGS. 6A and 6B, corresponds to a halving of the windshield wiper device; for example, at the location of the attachment 6, there will be an axis of rotation. Such an arrangement is often used for the rear window wiper. This case is represented by way of example among others in FIGS. 7A, 7B. Optional developments and details as described in the various embodiments can also be used generally in both variants of a windscreen wiper device. Figure 7A schematically shows another embodiment of the wiper device according to the invention. The wiper device is in this case a wiper arm incorporating a wiper blade 2 carried by a fastener 30. The fastener is connected to the motor 32 of the wiper which drives the fastener 30 to wipe the window 4. The wiper blade 2 is wedge-shaped and one end of the upper portion 10 is connected to the end of the lower portion 12 at a connecting position 34. The other respective end of the upper portion 10 and the lower portion 12 is connected to the fastener 30. Typically, for the basic construction and in particular the fasteners of the connecting elements 18 The windshield wiper of Figure 7A corresponds to what has been described above.

FIG. 7B schematically represents the wiper blade 2 incorporating the wiper arm 30 of FIG. 7A applied against the window 4. In this case also, thrust forces are exerted from below in the direction of the window 4 on the lower part 12 of the wiper blade 2 so that the lower part 12 and the upper part 10 bend toward the window 4. Both FIG. 6A and FIG. 7A show the wiper blade in its unapplied position against the window so that the lower portion 12 has a substantially rectangular shape.

According to other developments, the lower part, in the unsolicited state, has a convex shape, that is to say that it has a curved portion which, in the median position, deviates from the upper part. The wiper device according to the embodiments described herein may typically come into contact with the pane from the convex shape of the concave-shaped lower portion applied against the pane. Figure 8 is a schematic perspective view of a wiper blade 2 of a wiper device according to the invention. As shown in FIG. 8, at the outer connection positions, where the end of the elongate upper portion 10 and the elongate lower portion 12 are connected to each other, there is an outer width WE. According to the characteristic embodiments, the outer width WE is at least equal to 15 mm and in particular equal to at least 20 mm and more particularly equal to at least 25 mm. According to developments, the width of the wiper blade 2 from the outer connection position towards the fastener 30 or the attachment 6, where the wiper blade is attached to the arm wiper, increases. FIG. 8 shows, by way of example, the inside width carrying the reference WM. According to characteristic embodiments, the internal width WM is at least 20 mm, in particular at least 25 mm and especially at least 30 mm. Figure 9A is a diagrammatic representation of a detail of the wiper blade 2 of the embodiment of Figure 7A for the wiper blade 2 in the basic position. The figure shows the left end zone of the wiper blade 2 with one end of the upper part 10 and one end of the lower part 12 connected to the attachment part 30. FIG. 9A shows the first connection elements 18 from the junction between the fastener 30 and the wiper blade 2; these connecting elements delimit two wiper blade elements 36, 38. The connecting elements 18 are fixed to the upper part 10 and to the lower part 12 by rotation joints 20. FIG. 9B shows schematically a detail of the wiper blade 2 according to the embodiment of Figure 7B in which the wiper blade 2 is applied against the window 4. Pushing forces towards the window apply to the part lower 12. Representative for the thrust forces, Figure 9B shows a thrust 40. The thrust 40 deforms and bends the lower portion 12 of the wiper blade member 36. The pivot joint 20 the first connecting element 18 is thus shifted to the left of the distance (s). The second wiper blade element 38 flexes downward in the direction from which the thrust 40 comes to fit the window. Between the first wiper member 36 and the second wiper member 38 there is an angle 42. In addition, a further thrust force is developed which acts on the lower portion 12 of the second element. wiper blade 38 and prohibits further downward bending for the second wiper blade member 38. This results in a chain reaction to the adjacent wiper blade member, to the end of the wiper blade 2. A wiper lip 50 according to the embodiments described above is provided on the lower portion 12 of the wiper blade 2, for example on the wiper blades as shown by way of example in Figures 6A, 6B, 7A, 7B with a lip 50 according to the embodiments described herein. The wiper lip 50 wipes the window of the vehicle to clean it. The wiper blades are out of the tooling can thus be used directly in their preferred form. According to another development, for an advantageous and economical manufacture of the wiping lip and the wiper blade, the lower part 12 or the assembly of the wiper blade 2, also the upper part 10 and the connecting elements 18 are made of a first material. Typically, this first material will be or may be chosen for the different components of different materials. These materials are selected from the group consisting of TPE (thermoplastic elastomer), TPE-S, TPE-O, TPE-U, TPEA, TPE-V and TPE-E, which makes it possible to have advantageous materials to purchase and for use. The wiping lip 50 and the hinge 20 of the lower part 12 may be made of another material meeting the high requirements for flexural stiffness, creep resistance and other requirements. As for such an embodiment of a wiper blade joint or a wiper lip for the wiper blade, the amount of material used is limited, both for the joint and for the wiper blade. In the wiping lip, quality (and thus relatively expensive) materials can be used without increasing the total cost of the wiper blade beyond the limits. Rigid or relatively stiff ribs or a rigid connecting member may be provided for the selected upper and lower portions (selected) in a plastics material. It may be for example a plastic material reinforced by fibers. The hinge 20 and the rubber profile of the wiping lip 72 are made of a rubber-like material. The two different materials may for example be provided according to a two-component injection process. According to the typical embodiments, the rubber-like material is a TPE thermoplastic elastomer, for example TPE-S, TPE-O, TPE-U, TPE-A, TPE-V and TPE-E, ethylene-rubber. propylene-diene (EPDM); polychloroprene or natural rubber.

Optionally, the TPE joint can be supplied independently of the rubber profile, ie the wiping lip. In the same injection tool, however, one can also realize the rubber profile of the wiper lip and / or for example also give the surface an aesthetic appearance. Such a reduction of the injection tools makes it possible to reduce manufacturing costs.

Depending on the developments, materials may be selected to allow relatively high temperature variations and / or high ambient temperatures to be absorbed in a long-lasting manner, but still have a reliable and long-lasting wiper arrangement. The material of the hinge films, especially in connection with the thickness of the hinges, while respecting a flexural rigidity determined and further allows and in addition to achieve by an injection process to have the appropriate characteristics of the wiper blade for example, a sufficient resistance to the creep of rotation joints. According to the embodiments of the invention, described above, there will be a vehicle wiper device in a particularly advantageous manner and applicable to a large number of different application areas. A windscreen wiper device as described above, in particular with a removable "Fin-Ray" windscreen wiper blade, also includes a wiping lip and a cleaning device for cleaning windows. . The wiper device is suitable for a large number of application areas. In particular, it is thus possible to provide a windscreen wiper device which is simple and practical to handle and which allows for the user for several additional cleaning functions, and / or manual cleaning of the window. 25 NOMENCLATURE OF THE MAIN ELEMENTS 2 Wiper blade 4 Glass 10 Upper part 12 Lower part 18 Connecting element 20 Rotation joint 22 Distance 26 Angle between connecting element 18 and lower part 12 30 Fastening part 32 Wiper motor 34 External connection position 36 Wiper element 38 Wiper blade element 40 Pushing force 42 Angle 50 Fastening element 60 Standard adapter 70 Head piece, wiper blade side 71 Device for wiper blade actuation 73 Absorbent material 74 Brush 77 Fixing device 80 Scraper device 91 Scraper element WM Internal width30
