Here, a simpler structure of the wiper device, and / or an easier replacement of the wiper lip, and / or an improved fastening of the wiper lip can be achieved. Additionally, a modular structure can be achieved, which enables the manufacture of multiple construction variants by changing the individual components.

[0004] Furthermore, advantageous refinements and improvements of the features specified in the main claim are obtained by the measures recited in the dependent claims.

[0005] Advantageously, at least one void is provided at the retaining element of the composite component. Thereby, the retaining element can have high functionality.

Thus, a stable structure can be achieved, which ensures a reliable functional mode within the service life.

[0014] Advantageously, the retaining element has at least one U-shaped edge that is designed to be elastically deformable, and by elastic deformation of the U-shaped edge, a protrusion of the component can be guided into a cutout of a strip connected to the U-shaped edge. A plurality of protrusions can also be provided at the retaining element, and these protrusions can access the cutout at one U-shaped edge or, if necessary, at two U-shaped edges in the assembled state. Thereby, the U-shaped guide part can be pulled into a connection mechanism, especially a snapping mechanism. Thereby, high functionality is obtained.

[0015] Advantageously, a backsheet is provided, which is surrounded by at least one U-shaped edge at at least one longitudinal side in the assembled state, and the backsheet at least prevents elastic deformation of the U-shaped edge in the assembled state such that a form-fitting connection acting along the longitudinal extension is fixed against loosening. Thus, the stiffness of the wiper device can be ensured by the backsheet in the assembled state while simultaneously fixing the form-fitting connection. Thus, high functionality can be achieved with reduced assembly costs and a reduced number of components.

[0016] In addition, the following features and advantages can be achieved according to the design and application scenarios.

[0019] Advantageously, the retaining element of the combined component is constructed at least substantially from a harder raw material, the wiper lip is constructed at least substantially from a softer raw material, and the harder raw material has a higher strength than the softer raw material. Thereby, an advantageous material pairing can be achieved in a single component. Thus, high stability and optimized wiping power can be achieved in a combined manner in a targeted manner. Easy assembly can be achieved because the number of individual components to be installed can be reduced.

[0020] Advantageously, the combined component is configured as a co-extruded combined component. Thus, multiple raw materials can be combined in an advantageous manner to form a single component.

[0021] Advantageously, the retaining element of the combined component surrounds at least one backing sheet at at least one longitudinal side, in particular at two longitudinal sides. Thereby, reliable fastening can be achieved. In particular, the retaining element can surround the backing sheet for the longitudinal side or two longitudinal sides over at least substantially its entire longitudinal extent. Thereby, stability can be further improved.

[0022] The wiper device can be designed such that the preferably provided backing sheet does not have to have one or more cutouts in order to enable locking or fastening of the component.

[0027] It is particularly advantageous that at least one fastening adapter is provided, which is used for fastening to the wiper arm. The fastening adapter is arranged at least substantially at the side of the holding element facing away from the wiper lip, and the fastening adapter is connected to the composite member by means of at least one holding strip. Thereby, the composite member can be fastened to the wiper arm by the fastening adapter. Here, the fastening adapter can in particular be directly connected to the holding element. Fixing or locking along the longitudinal extent can also be achieved at the holding element. Thus, high functionality can be achieved. A simple structure can be achieved, in which in particular assembly can be realized with a smaller number of components and a common connection interface. In addition, in a preferred design, in this way, the end cap, the spoiler or the profile body and the fastening adapter can all be fastened to the same holding strip of the holding element of the composite member, which is designed at least substantially unchanged within the longitudinal extent.

[0028] It is advantageous that the wiper device is constructed at least substantially without a spoiler and / or without a profile body between the fastening adapter and at least one end cap. This design can also be achieved for two profile bodies or two spoilers with respect to two end caps. Here, the following design can also be achieved, in which the wiper device is designed in an open manner when viewed from above starting from the window pane, such that the upper side is at least partially arranged at the holding element and the backsheet of the composite member.

[0029] It is advantageous that at least one end cap is constructed at least substantially flat at the side facing away from the wiper lip. Thereby, a spoiler-free design of the wiper device can be achieved.

[0030] One or more of the following features and advantages can be achieved according to the design.

[0031] The wiper device can be realized according to the structure of a flat-frame wiper. Here, an integrated composite member can be provided at the flat-frame wiper, wherein the wiper lip, in particular the wiper rubber and the holding element, are integrated into the composite member.

[0032] The composite component has at least two elements to a certain extent, a wiper lip and a retaining element. However, additional elements can also be provided. The wiper lip ensures, for example, the function of contacting a window pane of a motor vehicle in order to scrape water off the window pane during operation. The retaining element holds, in a preferred embodiment, an end cap that can be adapted to the design of the end cap of a flat wiper, at least one, preferably two spoilers that can be configured as profile bodies, and a fastening adapter that is preferably arranged approximately centrally along the longitudinal extension.

[0033] The composite component can ensure the stability and structure of the wiper device through the retaining element. The retaining element can hold the back plate, the end cap, the one spoiler or preferably the plurality of spoilers, and the fastening adapter.

[0034] The composite component can preferably be extruded or co-extruded. At least two elements of the composite component, the retaining element and the wiper lip, can be manufactured as a single-piece component (monolithic) at least substantially from a single material (raw material), or alternatively from different materials (raw materials). In particular, in a preferred embodiment, the first material can be a soft material that is at least substantially used to construct the wiper lip.

The fastening adapter can be assembled at the retaining element, in particular in a manner of being pushed along the longitudinal extension. The fastening adapter can have at least one protrusion that mates with and engages in the one cutout or the plurality of cutouts during assembly.

[0038] The back piece is preferably adapted to access along the longitudinal extension, in particular to be pushed into the composite member along the longitudinal extension, following or shortly after the fastening operation of the fastening adapter to the holding element. The back piece can then block the preferably elastically deformable means for fastening the fastening adapter. In particular, it can thus block the protrusions of the fastening adapter in the cutouts of the holding element. A fixation of the fastening is thus obtained.

[0039] The holding element can have one or more cutouts, in particular incisions, for fastening the end cap. The cutouts are preferably provided at the holding strips of the holding element. The end cap preferably has at least one means which, during assembly, is inserted, in particular snapped, into the cutouts for the end cap. A non-loosenable connection is preferably achieved during assembly.

[0040] The design of the wiper device as a flat wiper can be achieved with or without at least one spoiler or profile body. In addition, a design of the wiper device, in particular a flat wiper, with a spoiler end cap or with a non-spoiler end cap can be achieved.

[0051] Figure 1 Shown in a schematic spatial view of a wiper device 1 according to a first embodiment, in particular for a motor vehicle. Furthermore, Figure 2 , Figures 3A to 3D , Figure 4 , Figure 5 , Figures 6A to 6D and Figures 7A to 7C show Figure 1 different views of the wiper device 1 shown in. The wiper device 1 can be used in particular for motor vehicles.

[0052] The wiper device 1 has a combined component 2. A retaining element 3 and a wiper lip 4 are integrated into the combined component 2. In this embodiment, the combined component 2 is formed at least substantially by the retaining element 3 and the wiper lip 4, such that the combined component is formed at least substantially by two elements 3, 4. However, in an altered design, the combined component 2 can also be formed by more than two elements 3, 4. The combined component 2 extends along the longitudinal extension 5 of the wiper device 1.

[0053] The wiper device 1 further has a backsheet 6. The holding element 3 of the composite member 2 holds at least one backsheet 6.

[0054] According to Figure 4 explain a possible design of the composite member 2, in which Figure 4 a schematic cross-sectional view is shown as a contour view. In this case, the composite member 2 can be constructed as a one-piece 2A, which includes not only the holding element 3 but also the wiper lip 4 and thus all the elements 3, 4 of the composite member 2.

[0055] This is a possible solution, that is, the composite member 2 is constructed at least substantially integrally and / or at least substantially from a single raw material 7. In particular, the composite member 2 can be constructed as an extruded composite member 2A.

[0056] According to Figure 5 explain an altered design of the composite member 2, in which Figure 5 a schematic cross-sectional view of the composite member 2, the contour body 22 or the spoiler 24 and the backsheet 6 is shown. In this case, the composite member 2 is constructed as a co-extruded member 2B.

[0057] Preferably, when manufactured from at least two raw materials, the holding element 3 of the composite member 2 is constructed at least substantially from a harder raw material 8, while the wiper lip 4 is constructed at least substantially from a softer raw material 9. The harder raw material 8 preferably has a higher strength than the softer raw material 9.

[0058] As shown in Figure 5 the holding element 3 of the composite member 2 can laterally surround the backsheet 6. The backsheet 6 has longitudinal sides 10, 11 that face away from each other. The holding element 3 surrounds the backsheet 6 with U-shaped edges 16, 17 at the two longitudinal sides 10, 11, and these edges extend within the longitudinal extension 5.

[0059] As shown in Figure 3A the backsheet 6 can be inserted between the U-shaped edges 16, 17 along the longitudinal extension 5 during assembly, as shown by the arrow 28.

[0060] As shown in Figure 5 the holding element 3 of the composite member 2 has fastening devices 14, 15 at its longitudinal sides 12, 13. The devices 14, 15 are preferably constructed as strips 14, 15 that extend along the longitudinal extension 5, and the strips are constructed as holding strips 14, 15 in this embodiment. In this embodiment, the holding strips 14, 15 are provided at two longitudinal sides 14, 15 that face away from each other, and the holding strips 14, 15 extend away from each other at least approximately in a common plane.

[0061] The contour bodies 22, 23 surround the holding strips 14, 15 of the holding element 3 in a U-shaped manner with U-shaped guides 26, 27, as exemplified by Figure 5 As shown in the spoiler 22 in FIG. It can thus be advantageously displaced along the directions 28 , 28 ′. It can advantageously be fastened to the retaining element 3 .

[0062] The holding element 3 of the composite component 2 thus has holding strips 14, 15 on its longitudinal sides 12, 13. In a corresponding manner, the components 20, 22, 23, 24, 25, 30, 31 have U-shaped guides 26, 27 which surround the holding strips 14, 15 on the longitudinal sides 12, 14.

[0063] Here, the holding element 3 of the composite component 2 has a first holding strip 14 at its first longitudinal side 12 and a second holding strip 15 at its second longitudinal side 13 facing away from the first longitudinal side 12. In this case, in a modified design, specific features can also be provided only at one of the holding strips 14, 15.

[0064] The components 20, 22, 23, 24, 25, 30, 31 have a first U-shaped guide 26 and a second U-shaped guide 27 in a corresponding manner. The first U-shaped guide 26 surrounds the first holding strip 14. The second U-shaped guide 27 surrounds the second holding strip 15. In this case, in a modified embodiment, it is also possible to provide specific features only on one of the U-shaped guides 26, 27.

[0065] As in Figure 5 , the retaining element 3 has means 18, 19 for fastening. The means 18, 19 are preferably designed as strips 18, 19. In the present exemplary embodiment, the strips 18, 19 are arranged on a side 21 of the retaining element 3 facing away from the wiper lip 4. The strips 18, 19 preferably extend away from the side 21, wherein an angle 32 of at least approximately 90° is preferably obtained relative to the side 21.

[0066] The strips 14 , 15 , 18 , 19 each preferably extend at least substantially over the entire longitudinal extension 5 .

[0067] As in Figure 3B As shown in FIG. 1 , a fastening adapter 20 for fastening to a wiper arm (not shown) can be fastened to the holding strips 14, 15, as indicated by the arrow 28. The fastening adapter 20 is arranged at least substantially on the side 21 of the holding element 3 facing away from the wiper lip 4 in the assembled state. Furthermore, the fastening adapter 20 can be locked along the longitudinal extension 5 by means of the strips 18, 19, as shown in FIG. Figures 6A to 6DAs described. Subsequently, the fastening adapter 20 is connected to the composite member 2 by means of the retaining strips 14, 15 and the strips 18, 19.

[0068] As shown in Figure 3C As shown in, the profile bodies 22, 23, which are arranged at least substantially at the side 21 of the retaining element 3 facing away from the wiper lip 4 in the assembled state, can likewise be connected to the composite member 2 by means of the retaining strips 14, 15, as shown by the arrows 28, 28'.

[0069] In the present embodiment, the profile bodies 22, 23 are configured as spoilers 24, 25. However, in a corresponding manner, differently configured profile bodies 22, 23 or spoilers 24, 25 can also be assembled and fastened.

[0070] As shown in Figure 3D As shown in, the end caps 30, 31 can likewise be connected to the composite member 2 by means of the retaining strips 14, 15, as shown by the arrows 28, 28'.

[0071] Thus, at least one additional member 20, 22, 23, 24, 25, 30, 31 can be provided, which is connected to the composite member 2 by means of the retaining strips 14, 15.

[0072] As shown in Figure 2 As shown in, a plurality of cutouts 35, 36, 37, 38, 39 are provided at the retaining element 3 of the composite member 2. In the present embodiment, the cutouts 35, 36, 37, 38, 39 are used to fasten the fastening adapter 20, the profile bodies 22, 23 or the spoilers 24, 25 and the end caps 30, 31 to the composite member, wherein the fixation or locking is achieved along the longitudinal extension 5. In combination with the fastening at the strips 16, 17, 18, 19, a reliable fastening is thus obtained.

[0073] In the present embodiment, the cutouts 35, 36, 37, 38, 39 are designed at the strips 14, 15, 18, 19. Here, in the present embodiment, the cutout 35 is provided at the strip 18. However, as an additional option or alternative, such cutouts can also be provided at the strip 19. In addition, one or more such cutouts 35 can be provided respectively. Furthermore, the cutouts 36, 37, 38, 39 are formed at the retaining strips 14, 15 here, wherein the cutouts 36, 37 are for the end cap 30 and the cutouts 38, 39 are for the end cap 31. The implementation scheme according to the end cap 30 applies correspondingly to the end cap 31.

[0074] Figures 6A to 6D An open, partially sectioned, schematic spatial illustration shows the Figure 1 and Figure 2The windshield wiper device 1 shown in the figure serves to explain the possible connection between the holding element 3 and the fastening adapter 20 of the composite component 2 in a plurality of assembly steps. The embodiment of the form-fitting connection between the holding element 3 and the fastening adapter 20 along the longitudinal extension 5 is shown here. Furthermore, the fixing or locking of the form-fitting connection by means of the backing sheet 6 is shown. Figure 5 The fixed or locked state for a form-fitting connection is also shown in FIG.

[0075] The U-shaped rim 16 of the retaining element 3 can be elastically deformed. The fastening adapter 20 can be pushed onto the retaining element 3 along the direction 28, as in Figure 3A and Figure 6A As shown in FIG. By the U-shaped edge 16 according to Figure 6B The elastic deformation of the arrow 40 shown in the figure can guide the protrusion 42 of the fastening adapter 20 into the recess 35 of the strip 18 connected to the U-shaped edging 16. When the U-shaped edging 16 is unloaded in the direction of the arrow 41 directed opposite to the arrow 40, a positive locking connection between the fastening adapter 20 and the composite component 2 is formed, as shown in Figure 6C As shown in Figure 6D As shown in , the form-fitting connection operates along the longitudinal extension 5 , ie in and against the direction of the arrow 28 .

[0076] In addition, the back sheet is installed along the direction of arrow 28, as shown in Figure 3B and Figure 6D When the back sheet 6 is mounted, it is surrounded by the U-shaped edges 16, 17 of the retaining element at its longitudinal sides 10, 11. This prevents the U-shaped edge 16 from being deformed to a great extent in the direction of the arrow 40, as shown in the example in FIG. Figure 6B As shown in FIG. 1 . Thus, in the assembled state, the back sheet 6 prevents at least a certain degree of elastic deformation of the U-shaped edge 16 in the direction 40, i.e., the connection 43 acting in a form-fitting manner along the longitudinal extension 5 can be loosened. The form-fitting connection is thus secured against loosening.

[0077] Figures 7A to 7C The schematic partial spatial view shows the assembly 2 and the end cap 30 in a plurality of assembly steps, wherein the implementation of the latching connection between the end cap and the assembly is shown. The end cap 30 has elastically deformable latching elements 46, 47, such as Figure 7A As shown in Figure 7B In the assembly along the arrow direction 28 shown in FIG. 1 , the latching elements 46, 47 are elastically deformed. The elastically deformed latching elements 46, 47 are then snapped into the recesses 36, 37 of the retaining strips 14, 15, as in FIG. Figure 7Cas shown. In the present embodiment, the cutout portions 36, 37 are provided at the longitudinal side portions 12, 13 of the holding element 3.

[0078] Figure 8A and Figure 8B FIG. schematically shows a windshield wiper device 1 in a spoilerless design according to a second embodiment, wherein Figure 8B FIG. shows details at the end cap 30 in a spatial view.

[0079] In the present embodiment, the windshield wiper device 1 is implemented without a spoiler. In addition, the windshield wiper device 1 is constructed without the profile bodies 22, 23 between the fastening adapter 20 and the end caps 30, 31. In addition, the end caps 30, 31 are constructed flat at the side portion 21 facing away from the wiper lip 4.

[0080] Accordingly, a windshield wiper device 1 that can be used especially for motor vehicles can be realized. The windshield wiper device 1 has at least a holding element 3 extending along a longitudinal extension 5 and a wiper lip 4. In addition, a combined member 2 extending along the longitudinal extension 5 is provided, and the combined member includes the holding element 3 and the wiper lip 4. In addition, at least one member 20, 22, 23, 24, 25, 30, 31 connected to the holding element 3 of the combined member 2 is provided. The combined member 2 has at least one cutout portion 35, 36, 37, 38, 39. At least one member 20, 22, 23, 24, 25, 30, 31 is locked to the combined member 2 by means of at least one cutout portion 35, 36, 37, 38, 39 of the combined member 2.

[0081] Figure 9A and Figure 9B FIG. schematically shows a windshield wiper device 1 according to a third embodiment, wherein latching elements 46, 47 are provided at the fastening adapter 20.

[0082] Here, Figure 9A the backsheet 6 is shown, wherein in the middle region 49, cutout portions 50, 51 are provided at the holding strips 14, 15 of the holding element 3 of the combined member 2. In such a design, at least with respect to the fastening adapter 20, the strips 18, 19 provided in the combined member 2 in the first embodiment can also be omitted.

[0083] Figure 9B The windshield wiper device 1 is also shown, wherein details are shown for showing a form-fitting connection 43 along the longitudinal extension 5 between the holding element 3 and the fastening adapter 20. The latching elements 46, 47 are constructed at the fastening adapter 20 and are preferably elastically deformable. When the fastening adapter 20 is pushed onto the holding element 3, as in the first embodiment, the fastening adapter has its U-shaped guides 26, 27 ( Figure 2)It is guided along the longitudinal extension 5 at the retaining strips 14, 15.
