Description

Title of the invention: Wiper, in particular for a windshield wiper system of a motor vehicle, comprising a structural part State of the art

[0001] The invention relates to a wiper, which can be used in particular for a windshield wiper system of a motor vehicle. The invention relates especially to the field of windshield wiper systems of passenger vehicles and trucks.

[0002] A windscreen wiper of flat construction is known from DE 10 2004 058 511 A1. The known windscreen wiper has wiper blades without a retaining bracket.

[0003] The invention relates to a wiper, in particular for a windshield wiper system of a motor vehicle, comprising a structural part and a wiping lip, which extend along a lengthwise extent, in which the wiping lip is mounted on the structural part, characterized in that at least one wiper element and a fixing adapter are provided, in that the structural part has a first long side and a second long side, which extend at least approximately parallel to the lengthwise extent, and in that the structural part envelops the at least one wiper element and the fixing adapter on its first long side and its second long side. This wiper has the advantage of having an improved conformation and mode of operation. It makes it possible to replace a wiping lip more simply and / or to fix it better.Overall, a modular structure can be realized which makes it possible to manufacture several construction variants by varying various parts.

[0004] The concept of wiper is to be understood broadly. The wiper may be designed in particular according to a flat windscreen wiper. The wiper may preferably be attached to a wiper arm or a similar actuating device of a wiping system, in particular a windscreen wiper system. The wiper may, in operation, wipe a window, in particular a windscreen. However, the wiper may also be suitable for other uses. For example, the wiper may also wipe a rear window in operation.

[0005] It is advantageous to provide an end cap which connects along the length to a wiper element, and for the structural part to envelop the end cap on its first long side and its second long side. The structural part can thus serve for the reliable fixing of the end cap.

[0006] It is advantageous to provide another end cap, which connects along the length to a wiper element, and which the structural part envelops the other end cap on its first long side and its second long side. This makes it possible for the structural part to provide reliable fixation of the other end cap.

[0007] It is advantageous to provide a recess on at least one of the long sides of the structural part, that the end cap has a stop element, in particular a latching element and that the stop element, in particular the latching element, of the end cap penetrates, in particular being latched, in the mounted state into the recess of the structural part. This makes simple assembly possible. Costly fastening solutions can thus be avoided.

[0008] Preferably, it is advantageous to provide a further recess on at least one of the long sides of the structural part, for the other end cap to have a stop element, in particular a latching element, and for the stop element, in particular the latching element, of the other end cap to penetrate, in particular by being latched, into the other recess of the structural part in the mounted state. This makes simple assembly possible. Costly fastening solutions can also be avoided.

[0009] It is advantageous to provide at least one back blade and for the back blade to be guided by the at least one element and the fixing adapter. By means of the back blade, stability can be further improved. In particular, advantageous force transmission from the fixing adapter to the other elements of the wiper can be made possible.

[0010] It is advantageous to provide an end cap and for the back blade to be guided, at least in places, by the end cap. This makes it possible to reliably fix the end cap. In addition, simple assembly can be ensured.

[0011] It is advantageous to provide another end cap and for the back blade to be guided, at least in places, by the other end cap. This makes it possible to reliably fix the other end cap. In addition, simple assembly can be ensured.

[0012] It is advantageous to conform at least one spoiler to at least one wiper element. An adaptation to the respective use case can thus take place. In particular, a wiper with high power efficiency can be produced, which makes reliable wiping possible, especially at high travel speeds.

[0013] It is advantageous to provide an end cap and to conform a spoiler to the end cap. This allows the efficiency of the wiper to be optimized, particularly for high-speed applications.

[0014] It is advantageous to provide another end cap and to conform a spoiler to the other end cap. This allows the efficiency of the wiper to be further optimized, particularly for high-speed applications.

[0015] It is advantageous to constitute the wiping lip and the structural part in a single piece. In this embodiment, replacement of the wiper after wear of the wiping lip can be carried out by replacing the structural part with the wiping lip.

[0016] It is advantageous if the wiping lip and the structural part are formed as a co-extrusion part. This makes it possible to advantageously form the wiping lip and the structural part into a single piece.

[0017] It is advantageous if a wiper lip mounting is formed on the structural part, which extends along the lengthwise extent and into which the wiper lip is inserted along the lengthwise extent. In this embodiment, if necessary, only the wiper lip can be replaced. A new wiper lip can then be inserted, for example, into the wiper lip mounting along the lengthwise extent.

[0018] It is advantageous if the structural part has recesses on its first long side. This allows the flexibility of the wiper to be adjusted in a targeted manner. This makes it possible, for example, to further optimize the wiping power.

[0019] It is advantageous if the structural part has recesses on its second long side. This allows the flexibility of the wiper to be adjusted in a targeted manner. This makes it possible, for example, to further optimize the wiping power.

[0020] It is advantageous for the recesses on the first long side of the structural part (2) to be spaced apart from each other with at least approximately a constant spacing. This makes it possible to achieve relatively uniform flexibility along the length. Overall, this makes it possible to achieve a symmetrical conformation of the structural part.

[0021] It is advantageous if the recesses on the second long side of the structural part are spaced apart from each other with at least approximately a constant spacing. This makes it possible to achieve relatively uniform flexibility along the length. Overall, this makes it possible to achieve a symmetrical conformation of the structural part.

[0022] It is advantageous if the recesses on the first long side of the structural part are spaced apart from each other by increasing or decreasing distances along the length. In this way, in the case of a respective use, a non-uniform bending characteristic along the length, in particular a bending rigidity which is not uniform, can be established.

[0023] It is advantageous for the recesses on the second long side of the structural part to be spaced apart from each other with increasing or decreasing distances depending on the length. It is thus possible to establish in each case of use a non-uniform bending characteristic along the length extent.

[0024] It is advantageous if the recesses on the first long side of the structural part along the lengthwise extent are shaped respectively with recess widths of the same dimension. This allows a uniform bending characteristic to be established along the lengthwise extent.

[0025] It is advantageous for the recesses on the second long side of the structural part to be spaced apart from each other with increasing or decreasing distances along the length. This allows for a uniform bending characteristic to be established along the length.

[0026] It is advantageous if the recesses on the first long side of the structural part along the lengthwise extent are shaped respectively to have recess widths of the same dimension. This allows a homogeneous bending characteristic to be established along the lengthwise extent.

[0027] It is advantageous for the recesses on the second long side of the structural part along the length to be shaped so as to have recess widths of the same dimension respectively.

[0028] This is another additional or alternative possibility for establishing in the respective use case a non-homogeneous bending characteristic along the length extent.

[0029] It is advantageous if the recesses on the second long side of the structural part along the length are shaped so as to have recess widths of the same dimension. This is another additional or alternative possibility for establishing in the respective case of use a non-uniform bending characteristic along the length.

[0030] In addition, the following characteristics and advantages can be achieved depending on the embodiment and the use case.

[0031] A wiper can be provided which makes it possible to simply exchange the wiping lip. An embodiment can thus be provided which makes it possible to simply replace a part of the wiper to replace the wiping lip. In one possible embodiment, only the wiping lip will have to be replaced. In another possible embodiment, the wiping lip is replaced together with another part of the wiper, in particular a structural part. In this way, a simple replacement can be achieved in particular, which can be carried out by a user, in particular by a vehicle driver.

[0032] The exchanger can be made in such a way that it makes possible at least partial decomposition of the wiper in a simple manner. A complete decomposition of the wiper can be made possible. The wiper can be shaped in such a way that the decomposition is also possible by a user, so that it is not necessary to send it to the workshop.

[0033] The wiper may be shaped in such a way that it can be mounted as a whole on a wiper blade or the like or can be removed therefrom. This can facilitate replacement of the wiper lip.

[0034] The structural part may surround other parts of the wiper on its long sides. For this purpose, the structural part may extend in a longitudinal direction along the lengthwise extent.

[0035] The wiper may include an attachment adapter, a first wiper member, a second wiper member, a first end cap, a second end cap, a back blade, and a structural member. The first wiper member and the second wiper member may each have a spoiler. The first end cap and the second end cap may each have a spoiler.

[0036] The fastening adapter can be threaded or slid between the first wiper element and the second wiper element on the backing blade. The fastening adapter can thus be arranged at least approximately in the middle between the first wiper element and the second wiper element. For this purpose, the first wiper element and the second wiper element can be designed to have the same length along the lengthwise extent. In particular, the first wiper element and the second wiper element can have the same design. The wiper elements can be threaded onto the backing blade. The end caps can also be threaded onto the ends of the backing blade.

[0037] The wiper can be shaped in accordance with a flat windshield wiper. In this regard, one or more back blades can be provided. Spoilers can also be provided on parts of the wiper. The end caps, the wiper elements and the fastening adapter can have on the long sides respectively rails or rail pieces, which are joined to each other when the parts are arranged next to each other along the length. Rails or respectively rail pieces then consist in a certain way into a rail on which the structural part can be placed or respectively slid on both sides.

[0038] This embodiment can be implemented in such a way that the structural part can be disassembled in a simple manner and, if necessary, reassembled. This makes it possible in a corresponding use case to simply exchange the structural part, in particular together with a wiping lip.

[0039] It is thus made possible, when the relevant parts of the wiper are oriented along the lengthwise extent, to slide the structural part on the parts threaded together by means of the back blade, in particular the wiper elements, the fixing adapter and the end caps.

[0040] In the assembled state, the structural part can surround, at least essentially over the entire extent in the longitudinal direction on the long sides, the parts assembled together by plugging by means of the back blade.

[0041] The structural part and the wiping lip can perform two different functions and be shaped accordingly. The wiping lip can be made of a soft material, which is suitable for cleaning a window, in particular a windshield. The structural part can be made of a material, which is suitable for the desired stability and mechanical rigidity. The structural part can be formed in particular by the choice of material in the form of a rigid structural part. This can optimize the mechanical stability of the wiper.

[0042] The structural part and the wiping lip are preferably formed as a coextruded part (coextrusion part). However, in an alternative embodiment, the wiping lip can also be assembled to the structural part in another way. In one possible embodiment, the wiping lip is assembled in a form-fitting manner to the structural part. A disassembly of the wiping lip from the structural part and thus a replacement of only the wiping lip can thus in particular be made possible.

[0043] The wiper can be disassembled (disassembled) in a simple manner and reassembled (reassembled). A locking mechanism is used for this purpose. In a preferred embodiment, a stop element, in particular a latching element, is provided on at least one of the end caps, which engages in a recess in the structural part. This makes it possible to simply end the stop so that, for example, a user, in particular a vehicle driver, can simply disassemble the structural part. The stop element can, for example, be actuated by pressure. In an alternative embodiment, the stop element can also be actuated by pulling. Other possibilities for actuating the stop element can also be envisaged. The stop element can also be designed in the form of a drawer.

[0044] In an embodiment, in which only one of the two end caps has a stop element, the end cap having the stop element may be provided either at one or the other end of the wiper. In a wiper which, in accordance with a rotational movement of the wiping arm, passes over the window, the end cap having the stop element is located inside or outside, respectively on the outer or inner circle.

[0045] In one embodiment of the stop in the form of a latching mechanism, there may be automatic latching during assembly of the structural part, when the parts are in their predefined positions relative to each other. The latching mechanism can in this respect enable the latching element to snap into place in the recess. This snap-in can be linked to acoustic feedback from the user. The wiper can thus be intuitively reassembled by the user after replacing the wiper lip.

[0046] The latching element is preferably under stress during the assembly process or during mounting until it engages in the recess. By pushing the latching element back in again, the wiper lip can then be replaced again.

[0047] In an alternative embodiment, the latching element can also be pulled to release the stop. The latching element can in particular be designed in such a way that a user pulls a button on the latching element to release the stop. In this embodiment too, during assembly or mounting, a pre-stress is preferably applied to the latching element until it snaps into the recess.

[0048] The stop can therefore be terminated, in particular, by a user pushing or pulling the latching element out of the recesses of the structural part and, for example, bending a tab so that the latching element is under prestress, which is relevant during assembly.

[0049] A recess which serves as a stop can thus be arranged on the structural part so that the latter is directed inwards.

[0050] The structural part may have several recesses which serve to influence the bending rigidity of the structural part and thus of the wiper. There may thus be, in particular for a curved window, an adaptation to ensure application of the wiper over at least substantially its entire length.

[0051] The recesses can be specially adapted in their size, number and arrangement to the bending characteristic of the back blade. The recesses can be distributed at constant distances or intervals over the lengthwise extent. In an alternative embodiment, increasing or decreasing distances or intervals are also preferred. But other variants are also possible.

[0052] In one possible embodiment, the recesses are of the same shape or at least have the same width along the length.

[0053] Furthermore, the recesses can be shaped to influence the bending characteristic along the longitudinal axis also by different geometries, in particular by different recess widths along the length. In this way, a bending stiffness that varies along the length can be achieved if necessary.

[0067] Embodiments of the invention

[0068] [Fig.l] represents an exchanger 1 in a schematic perspective view corresponding to a first embodiment example. In this respect, [Fig.l] represents a mounted state of the wiper. [Fig.2] represents the wiper 1 shown in [Fig.l] in a panoramic representation 1, a completely disassembled state of the wiper 1 being shown. The wiper 1 is particularly suitable for windshield wiper systems of motor vehicles.

[0069] The wiper 1 comprises a structural part 2 and a wiping lip 3. The wiping lip 3 is mounted on the structural part 2. The structural part 2 and the wiping lip extend along a length 4.

[0070] The wiper 1 further has wiper elements 5, 6 and a fixing adapter 7. In this exemplary embodiment, for example, a first wiper element 5 and a second wiper element 6 are provided.

[0071] The structural part 2 can be attached to the wiper elements 5, 6 and has a fastening adapter 7. The structural part 2 has a first long side 8 and a second long side 9, which extend at least approximately parallel to the lengthwise extent 4. The structural part 2 envelops the wiper elements 5, 6 and the fastening adapter 7 arranged between the wiper elements 5, 6 on its first long side 8 and its second long side 9.

[0072] The wiper 1 further has at least one back blade 10. In this embodiment, exactly one back blade 10 is provided. The back blade 10 is guided by the first wiper element 5, then by the fixing adapter 7 and then by the second wiper element 6.

[0073] It is possible to ensure a high stability of the assembly between the parts, which comprise wiper elements 5, 6, the fixing adapter 7, the back blade 10 and the structural part 2.

[0074] In this embodiment, the wiper 1 has an end cap 15 and another end cap 16. The end cap 15 is connected, considered along the length 4, to the outside of the first wiper element 5. In the assembled state, the structural part 2 also envelops the end cap 15 by its first long side 8 and its second long side 9.

[0075] The other end cap 16 is connected, considered along the length 4, on the outside to the second wiper element 6. In the assembled state, the structural part 2 also envelops the other end cap 16 by its first large side 8 and its second large side 9. The end cap 15 and the other end cap 16 are arranged at opposite ends of the wiper 1.

[0076] There is also furthermore an assembly between the back blade 10 and the end caps 15, 16. The back blade 10 is in this respect guided at least in places by the end cap 15. In this embodiment, the back blade 10 is inserted into the end cap 15. The back blade 10 may have, for example, openings 19 into which suitable assembly beaks or the like penetrate into the end caps 15, 16 to obtain a reliable assembly in the lengthwise direction 4 between the end caps 15, 16 and the back blade 10.

[0077] In addition, the back blade 10 is guided at least in places by the other end cap 16. In this embodiment, the back blade 10 is inserted into the end cap 16.

[0078] The assembly between the parts of the wiper 1, including the end caps 15, 16, can thus be achieved with great stability. In particular, advantageous guidance of the wiping lip 3 on a window of a motor vehicle can thus be obtained.

[0079] Depending on the respective use case, one or more parts of the wiper 1 can be adapted to suit. The modular structure of the exchanger 1 can in this respect allow the wiper 1 to be mounted in accordance with a principle of standardized elements so that the number of part variants can be optimized.

[0080] In one possible embodiment, spoilers 11, 12 are, as in this exemplary embodiment, shaped on wiper elements 5, 6. In addition, spoilers 13, 14 are shaped on the end caps 15, 16.

[0081] [Fig. 3] is a schematic representation to explain an assembly of the wiper 1 shown in [Fig. 1]. The parts assembled by the back blade 10 are formed in this respect by a lateral rail 17 and another lateral rail 18, which is opposite the rail 17. The rails 17, 18 extend along the length 4.

[0082] The structural part 2 is inserted onto the rails 17, 18 in such a way that its large sides 8, 9 envelop the rails 17, 18 in a U-shape. This will be explained further in the following also with the aid of figures 4 and 5.

[0083] [Fig.4] shows a structural part 2 and a wiping lip 3 of the wiper 1 shown in [Fig.1] in a sectional view according to a possible embodiment, the sectional view being oriented transversely to the length 4 and the structural part 2 and the wiping lip 3 being coextruded.

[0084] In this embodiment, the wiping lip 3 and the structural part 2 are thus a single piece. In particular, the wiping lip 3 and the structural part 2 are in the form of a coextrusion part 20.

[0085] [Fig.5] represents the section shown in [Fig.4] of a structural part 2 and a wiping lip 3 in accordance with another possible embodiment, the structural part 2 and the wiping lip 3 being independent parts.

[0086] In this embodiment, a wiping lip mount 21 extending along the length 4 is formed on the structural part 2. The wiping lip 3 is inserted into the wiping lip mount 21 along the length 4. In particular, the wiping lip can be removable and for this purpose, pulled out of the wiping lip mount along the length 4. The wiping lip mount 21 has L-shaped guides 22, 23 which envelop a T-shaped part 24 of the wiping lip 3.

[0087] Furthermore, the structural part 2 has on its long sides 8, 9 U-shaped guides 25, 26, which in the assembled state envelop the rails 17, 18 ([Fig. 3]). The U-shaped guides 25, 26 are turned towards each other by their open side.

[0088] [Fig.6] shows a detail of the structural part 2 of the wiper 1 shown in [Fig.l], in which a recess 28 is shown in the structural part 2, which serves as a stop in the assembled state. Furthermore, [Fig.7] shows a detail of an end cap 15 of the wiper 1 shown in [Fig.l], the end cap 15 having a stop element 29, which in the assembled state enters the recess 28 shown in [Fig.6]. Furthermore, [Fig.8] shows a detail of the wiper 1 shown in [Fig.l], the stop element 29 shown in [Fig.7] entering the recess 28 shown in [Fig.6]. For the sake of clarity, directions X have been drawn, which coincide along the length 4 in Figures 6 to 8.

[0089] At least one recess 28 is provided on at least one of the long sides 8, 9 of the structural part 2. In this embodiment, exactly one recess 28 is provided. Furthermore, the stop element 29 is formed in this embodiment in the form of a latching element 29. The stop element 29 of the end cap 15 penetrates into the recess 28 of the structural part 2 in the assembled state. In this embodiment, the latching element 29 is latched into the recess 28.

[0090] In an alternative embodiment, a further recess 28 may be provided on at least one of the long sides 8, 9 of the structural part 2, which serves for a further end cap 16. The further end cap 16 may then have a corresponding stop element 29, in particular a latching element 29. The latching element 29 of the further end cap 16 then enters the further recess 28 of the structural part 2 in the mounted state, latching being possible in particular.

[0091] [Fig.9] represents the structural part 2 shown in [Fig.2] of a wiper 1 according to a second exemplary embodiment, in a schematic perspective representation to explain possible embodiments. In this exemplary embodiment, the structural part 2 has recesses 38 on its first large side 8. The structural part 2 also has recesses 39 on its second large side 9.

[0092] In one possible embodiment, the recesses 38 on the first large side 8 of the structural part 2 are spaced apart from each other by at least approximately a constant distance L1. In addition or alternatively, the recesses 39 on the second large side 9 of the structural part 2 are spaced apart from each other by at least approximately a constant distance L1. The distances constants on the first long side 8 may be different from the constant distances on the second long side 9.

[0093] In an alternative embodiment, the distances on at least one of the long sides 8, 9 are different from each other. In a preferred alternative, the recesses 38 on the first long side 8 of the structural part 2 are spaced apart by a distance L1, L2 that increases or decreases along the length 4, only the distances L1, L2 having been drawn to simplify the representation.

[0094] Additionally or alternatively, the recesses 39 on the second large side 9 of the structural part 2 are spaced apart by a distance L1, L2 increasing or decreasing along the length 4. The distances chosen for the first large side 8 may also be different from the distances chosen for the second large side 9.

[0095] [Fig. 10] shows the detail represented by X in [Fig. 9] of the structural part 2 in order to explain other possible embodiments of the wiper 1. In this exemplary embodiment, the recesses 38 on the first long side 8 of the structural part 2 along the length 4 are shaped to have the same recess widths L4 respectively. Furthermore, the recesses 39 on the second long side 9 of the structural part 2 along the length 4 are shaped to have the same recess widths L4 respectively. The recess widths on the first long side 8 and the second long side 9 are also different from each other.

[0096] In an alternative embodiment, the recesses 38 on the first large side 8 of the structural part 2 along the length 4 are shaped to have widths L3, L4 of recesses that increase or decrease along the length 4, only the widths L3, L4 of the recesses being shown to simplify the representation.

[0097] In addition or as a variant, the recesses 39 on the second large side 9 of the structural part 2 along the length 4 are shaped to have widths L3, L4 of recesses that increase or decrease along the length 4. Different embodiments can be made on the first large side 8 and the second large side 9.

[0098] The invention is not limited to the embodiments described.
