[0015] Preferably, the second wiper element has a first recess, which faces the first long side of the structural part and into which the first back blade is inserted, and the second wiper element has a second recess, which faces the second long side of the structural part and into which the second back blade is inserted. Mounting is thus possible.

[0016] Preferably, the first recess is shaped as a receiving slot extending along the lengthwise extent in the first wiper element and / or the second recess is shaped as a receiving slot extending along the lengthwise extent in the first wiper element. This makes it possible to securely and reliably attach the first wiper element to the back blades.

[0017] Preferably, the first recess is shaped as a receiving slot extending along the lengthwise extent in the second wiper element and / or the second recess is shaped as a receiving slot extending along the lengthwise extent in the second wiper element. This makes it possible to securely and reliably attach the first wiper element to the back blades.

[0018] Preferably, an end cap is provided, which connects to a wiper element along the lengthwise extent, and the structural part envelops the end cap on its first long side and on its second long side. This makes it possible to reliably attach the end cap to the structural part.

[0019] Preferably, a further end cap is provided, which connects to a wiper element along the lengthwise extent, and the structural part envelops the further end cap on its first long side and its second long side. This makes it possible to reliably attach the further end cap to the structural part.

[0020] Preferably, a recess is provided on at least one of the long sides of the structural part, the end cap has a stop element, in particular a latching element, and the stop element, in particular the latching element, of the end cap penetrates into the recess of the structural part in the assembled state, in particular being latched therein. This allows for reliable fastening, and thus also allows for simple assembly and disassembly. A user, in In particular, a vehicle driver can replace a wiper lip without a trip to the workshop.

A user, in particular a vehicle driver, can thus carry out a replacement of a wiper lip without a stay in a workshop.

[0022] It is advantageous to form at least one spoiler on at least one wiper element. In this possible embodiment, at least one wiper element can form a spoiler. This can make it possible, in particular when assembling the wiper according to a modular system, to rely on the same already produced parts, in particular wiper elements, possibly with or without a spoiler.

[0023] It is advantageous to provide an end cap and to conform a spoiler to an end cap. This embodiment is particularly advantageous with a spoiler provided on the wiper element belonging to it, in order to extend a spoiler.

[0024] It is advantageous to provide another end cap and to conform a spoiler to the other end cap. This embodiment is particularly advantageous with a spoiler provided on the wiper element, which is associated with it, in order to extend a spoiler.

[0025] It is advantageous to provide an end cap and to guide the at least one back blade at least in places by the end cap. This allows for an advantageous attachment of the end cap to the back blade.

[0026] It is advantageous to provide another end cap and for the at least one back blade to be guided at least in places by the other end cap. This can thus provide an advantageous attachment of the other end cap to the back blade.

[0027] It is advantageous if the wiping lip and the structural part are made of a single piece. This provides a reliable attachment of the wiping lip to the structural part, which immediately prevents the wiping lip from moving relative to the structural part along the length.

[0028] It is advantageous if the wiping lip and the structural part are formed as a coextrusion part. This makes a reliable connection possible with optimized manufacturing costs.

[0029] Preferably, on the structural part is formed a wiping lip mount, which extends along the lengthwise extent and in which the lip wiper is inserted along the length. In this embodiment, if necessary, only the wiper lip can be exchanged, so that the structural part can be reused.

[0030] Preferably, the structural part has at least one, in particular exactly one, spoiler mounted on its first long side. In this embodiment, a spoiler can be produced in an advantageous manner. If necessary, assembly can be carried out according to a modular module system so that, depending on the use case, an embodiment is possible with or without a spoiler. It is thus possible to reduce the manufacturing cost of an embodiment for various use cases.

[0031] For example, an embodiment with a spoiler can be provided for vehicles or vehicle markets in which a high wiper power capacity is desired even at high speeds.

[0032] It is advantageous if the structural part has at least one, in particular exactly one, spoiler mounted on its second long side. In this embodiment, a spoiler can be produced in an advantageous manner. If necessary, assembly can be carried out according to a modular module system so that, depending on the use case, an embodiment with or without a spoiler is possible. It is thus possible with reduced manufacturing costs to have an embodiment for various use cases. For example, an embodiment with a spoiler can be produced for vehicles or vehicle markets in which a high wiper power capacity is desired even at high speeds.

[0033] In particular, in an embodiment of the structural part having at least one spoiler, it is possible to dispense with a spoiler on the wiper elements and the end caps. However, an overall embodiment without a spoiler for the wiper is also possible.

[0034] The structural part can also serve for the reliable fixing of the end cap and / or the other end cap.

[0035] It is advantageous to provide a recess on at least one of the long sides of the structural part, for the end cap to have a stop element, in particular a latching element, and for the stop element, in particular the latching element, of the end cap to penetrate into the recess of the structural part in the assembled state, in particular being latched therein. This makes simple assembly possible. Costly fastening solutions can be avoided.

[0036] It is advantageous to provide on at least one of the long sides of the structural part a further recess, that the other end cap has a stop element, in particular a latching element and that the stop element, in particular the latching element, of the other stop cap penetrates in the mounted state into the other recess. of the structural part, in particular by being clipped into it. This makes simple assembly possible. Costly fixing solutions can be avoided.

[0037] The following characteristics and advantages can also be achieved depending on the embodiment and the use case.

[0038] A wiper can be provided which makes it possible to simply exchange the wiping lip. An embodiment can be provided which makes it possible to replace only a part of the wiper, in order to change the wiping lip. In one possible embodiment, only the wiping lip can be replaced. In another possible embodiment, the wiping lip can be replaced together with another part of the wiper, in particular with a structural part. In this way, in particular, a simple replacement can be achieved, which can be carried out by a user, in particular by a driver of the vehicle.

[0039] The wiper can be made in such a way that at least partial decomposition of the wiper is possible in a simple manner. It may also be possible to have a complete decomposition of the wiper. The wiper can be shaped in such a way that decomposition is also possible by a user, so that a stay in a workshop is not necessary.

[0040] In an advantageous embodiment, the wiper elements attached to the at least one back blade and / or the attachment adapter are securely attached to each other so that these parts cannot be separated from each other.

[0041] The wiper may be shaped such that it can be mounted as a whole on a windshield wiper blade or the like and can be removed therefrom. This may facilitate replacement of the wiping lip.

[0042] In the wiper, the at least one blade can be accessible on its long sides, at least substantially over the entire length, in order to make it possible to attach it to the structural part.

[0043] The structural part may comprise other parts of the wiper on its long sides. The structural part may comprise in particular an end cap and another end cap on its long sides. The structural part may extend in a longitudinal direction along the lengthwise extent.

[0044] Since the structural part is connected on its large outer sides to the back blade or blades, a particularly rigid embodiment can be achieved. A particularly rigid attachment of the wiping lip to the wiper, as well as to the attachment adapter, can be achieved. This makes it possible to achieve high wiping power.

[0045] 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 The first end cap and the second end cap may each have a spoiler.

[0046] The fastening adapter can be plugged onto the backing plate between the first wiper element and the second wiper element. The fastening adapter can be arranged at least approximately centrally on the backing plate or respectively 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.

[0047] The fixing adapter can also be mounted at least approximately in the middle on several back blades.

[0048] The wiper elements and / or the fastening adapter can be inserted at least approximately perpendicular to the lengthwise extent onto the back blade. The end caps can also be inserted onto the ends of the back blade.

[0049] The attachment adapter and / or the wiper elements can be indissolubly assembled to the at least one wiper. In particular, welding, hot pressing or the like is possible in order to assemble the parts together. This assembly can also be carried out in a form-fitting assembly, so as to obtain an assembly without gaps and / or which can very well withstand a load.

[0050] The fastening adapter may also have a fastening projection, in which approximately four fastening projections, in particular exactly four fastening projections, are preferably provided. These fastening projections can be inserted into a corresponding number of fastening recesses, in particular fastening holes. In particular by welding, hot pressing or the like, the parts can be further joined together. In this way, an indissoluble connection can be achieved.

[0051] Correspondingly, wiper elements with more than one fixing blade can be assembled by welding, hot pressing or the like.

[0052] The exchanger may be shaped in accordance with a windshield wiper device. One or more back blades may be provided for this purpose. Spoilers may also be provided on the parts of the exchanger. The spoilers may be provided on the wiper elements and / or on the structural part. However, an embodiment without spoilers is also possible.

[0053] The end caps may have on the long sides respectively rails or rail pieces, which are assembled at the ends on the corresponding rail pieces of the at least one back blade, when the pieces are stored next to each other along the length. The rails or pieces of rail then form, so to speak, a rail, on which the structural part can be placed or moved on both sides.

[0054] This embodiment can be implemented in such a way that the structural part can be easily dismantled and, if necessary, also reassembled. This makes it possible in this use case to easily assemble the structural part, in particular together with a wiping lip.

[0055] In the assembled state the structural part may surround the back blade or the back blades together with the end pieces at least substantially over its entire extent in the longitudinal direction on the long sides.

[0056] The at least one back blade can, together with the parts mounted thereon, in particular the fixing adapter, if applicable the wiper elements and the end pieces, be inserted into the structural part. Simple assembly is thus possible.

[0057] The wiper can be disassembled (disassembled) in a simple manner and reassembled (reassembled). A locking mechanism can be used for this purpose. In a preferred embodiment, a stop element, in particular a latching element, is provided at least on one end cap, which engages in a recess in the structural part. The stop can thus be ended in a simple manner, so that, for example, a user, in particular a driver of the vehicle, can easily 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 considered. The stop element can, for example, also be designed as a drawer.

[0058] In an embodiment in which only one of the two end caps has a stop element, the end cap having the stop element is provided either at one or the other end of the wiper. In a wiper which passes, in accordance with a rotational movement of a blade, over the window, the end cap having the stop element may be located inside or outside, respectively on the outer or inner circle.

[0059] In one embodiment of the stop in the form of a latching mechanism, automatic latching can take place during assembly of the structural part, when the parts are in their prescribed positions relative to each other. The latching mechanism can enable the latching element to latch into the recess. This latching can be accompanied by an acoustic feedback message to the user. The wiper can thus, after replacement of the wiping lip, be reassembled in good order by the user in an intuitive manner.

[0060] The latching element is preferably under stress during assembly or mounting until it engages in the recess. By pressing the latching element back in, the wiper lip can then be replaced again.

[0061] In an alternative embodiment, the latching element can also be pulled out to end the stop. The latching element can in particular be designed in such a way that a user, in order to end the stop, pulls out a button on the latching element. In this embodiment, too, the latching element is preferably pre-tensioned during assembly or mounting until it engages in the recess.

[0062] In particular, the stop can also be terminated by a user pushing or pulling the latching element out of the recesses of the structural part and thus bending, for example, a tab, so that the latching element is under pre-stress, which is relevant for assembly.

[0063] A recess which serves for stopping can be arranged on the structural part so as to be turned inwards.

[0064] 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 mechanical stability and rigidity. The structural part can in particular be formed by the choice of material in the form of a rigid structural part. This can optimize the mechanical stability of the wiper.

[0065] 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 can be assembled in a form-fitting manner with the structural part. In particular, it can be made possible to disassemble the wiping lip from the structural part and thus replace only the wiping lip.

[0066] The structural part can be made up of one or more spoilers. Depending on the embodiment, the spoiler(s) and the structural part can also be coextruded. However, other embodiments are also possible. For example, the spoiler(s) can also be clipped onto the structural part or assembled to the structural part in another way. This can, if necessary, standardize the manufacture of the structural part, particularly within the framework of a modular system. This also allows the assembly of a structural part without a spoiler, if, for example, a wiper without a spoiler is to be manufactured.

[Fig. 6] further represents a corresponding detail of [Fig. 4], an assembly of the alternative embodiment of [Fig. 5] being explained. [Fig. 7] further represents a detail of the alternative embodiment represented in Figures 5 and 6.

[0102] In this embodiment, exactly one back blade 15 is provided. The fixing adapter 7 is, as shown in [Fig. 6], assembled to the back blade 15, by the fact that the fixing adapter 7 is plugged in the 30' direction onto the back blade 15. This has the same meaning as the back blade being plugged in the 30 direction, i.e. in the opposite direction to the 30' direction, onto the fixing adapter 7. The fixing adapter 7 and the back blade 15 can thus be assembled.

[0103] In particular in this embodiment, the back blade 15 has fastening openings 31, 32, 33, 34. The fastening adapter 7 can be inserted in a form-fitting manner into the fastening openings 31, 32, 33, 34 of the back blade 15. Fastening projections 41, 42, 43, 44 are formed for this purpose on the fastening adapter 7.

[Fig. 10] further shows the end cap 17 to explain the stop, a stop element 51, which in the mounted state penetrates into the recess shown in [Fig. 9], being shown. To make the assembly relationships clearer, a direction IX has been characterized in Figures 9 and 10 respectively.

[0107] The stop element 51 is constituted in this embodiment in the form of a snap-in element 51. The snap-in element 51 of the end cap 50 is in the mounted state snapped into the recess 50 of the structural part 2.
