[0024] A wiper device can be realized according to the structure of a flat-frame wiper. An integrated composite component can be provided at the flat-frame wiper, wherein a wiper lip, in particular a wiper rubber, and a retaining element are integrated into the composite component.

[0025] To a certain extent, the composite component has at least two elements, namely the wiper lip and the retaining element. However, additional elements can also be provided. The wiper lip ensures, for example, the function of contacting the window pane of a motor vehicle in order to wipe water off the window pane during operation. In a preferred embodiment, the retaining element holds an end cap that can be adapted to the design of the end cap of the flat-frame wiper, at least one, preferably two spoiler elements that can be configured as profile bodies, and a fastening adapter that is preferably arranged approximately centrally along the longitudinal extension.

[0026] The back plate can ensure a firm and / or rigid connection for the end cap and the fastening adapter. Thereby, it is possible to prevent the end cap and the fastening adapter from shifting along the longitudinal extension.

[0027] 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 multiple spoilers, and the fastening adapter.

[0028] The composite component can preferably be extruded or co-extruded.

[0031] The backsheet preferably has a recess, which can be realized in the form of a notch. Such a recess enables a fixing member to be realized, in order to limit, in particular, the degree of freedom of the movement along the longitudinal direction. Subsequently, it is possible to limit all degrees of freedom of the movement, in particular in combination with the fastening at the holding element. For this purpose, it is also necessary to limit the relative movement along the longitudinal extension between the backsheet and the combined member, which can be realized, for example, by an end cap.

[0032] The latching protrusion of the end cap and at least one latching protrusion of the fastening adapter can be snapped into the recess of the backsheet. However, other feasible solutions for the connection can also be realized. The design solution realized by means of the latching protrusion or another latching connection has the advantage that the assembly can be carried out without tools if necessary. One or more latching connections can be realized in such a way that they cannot be loosened.

[0033] The design of the wiper device as a flat-frame wiper can be realized with or without at least one spoiler or profile body. In addition, it is possible to realize a design of the wiper device, in particular a flat-frame wiper, with a spoiler end cap or with a non-spoiler end cap. One or more spoilers can be configured as air deflectors here. Description of the Drawings

[0044] Figure 1 shows in a schematic, spatial illustration the wiper device 1 according to a first embodiment, in particular for a motor vehicle. Furthermore, Figure 2 , Figures 3A to 3D ,Figure 4A and Figure 4B 、 Figure 5A and Figure 5B 、 Figure 6A and Figure 6B 、 Figures 7A to 7C and also Figure 8A and Figure 8B show Figure 1 different views of the wiper device 1 shown in . The wiper device 1 can be used in particular for motor vehicles.

[0045] The wiper device 1 has a composite member 2. A holding element 3 and a wiper lip 4 are integrated into the composite member 2. In the present embodiment, the composite member 2 is formed at least substantially by the holding element 3 and the wiper lip 4, such that the composite member is formed at least substantially by two elements 3, 4. However, in a modified design, the composite member 2 can also be formed by more than two elements 3, 4. The composite member 2 extends along the longitudinal extension 5 of the wiper device 1.

[0046] The wiper device 1 furthermore has a back plate 6. The holding element 3 of the composite member 2 holds at least one back plate 6.

[0047] According to Figure 4A and 4B explain possible designs of the composite member 2, where a general spatial view is shown in Figure 4A and a contour view is shown in Figure 4B viewed from the line of sight direction indicated by IV-B in Figure 4A . In this case, the composite member 2 can be configured as a one-piece 2A, which includes not only the holding element 3 but also the wiper lip 4, and thus includes all the elements 3, 4 of the composite member 2.

[0048] This is the following possible solution, namely: 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 configured as an extruded composite member 2A.

[0049] According to Figure 5A and Figure 5B explain a modified design of the composite member 2, where a general spatial view is shown in Figure 5A and a contour view is shown in Figure 5B viewed from the line of sight direction indicated by V-B in Figure 5A . In this case, the composite member 2 is configured as a co-extruded member 2B.

[0050] Preferably, when produced from at least two materials, the retaining element 3 of the composite component 2 is at least substantially formed from the harder material 8, while the wiper lip 4 is at least substantially formed from the softer material 9. The harder material 8 preferably has a higher strength than the softer material 9.

[0051] As in Figure 4B Or Figure 5B As shown in the figure, the holding element 3 of the composite component 2 can be laterally wrapped around the back sheet 6. The back sheet 6 has longitudinal sides 10, 11 that are separated from each other. The holding element 3 wraps around the back sheet 6 at the two longitudinal sides 10, 11 with U-shaped edges 16, 17, which extend within the range of the longitudinal extension 5.

[0052] As in Figure 3A As shown in , the back piece 6 can be inserted along the longitudinal extension 5 during assembly between the U-shaped edges 16 , 17 , as indicated by the arrow 18 .

[0053] As in Figure 4B Or Figure 5B As shown in FIG. 1 , the holding element 3 of the composite component 2 has means 14, 15 for fastening at its longitudinal sides 12, 13. The means 14, 15 are preferably configured as holding strips 14, 15 extending along the longitudinal extension 5. In the present embodiment, the holding strips are arranged at two longitudinal sides 14, 15 facing away from each other, wherein the holding strips 14, 15 extend away from each other at least approximately in a common plane.

[0054] 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 5B As shown in the spoiler 22 in FIG. It can thus be advantageously displaced along the directions 18 , 18 ′. It can advantageously be fastened to the retaining element 3 .

[0055] As in Figure 3B , 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 18. 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. The fastening adapter 20 is then connected to the assembly 2 by means of the holding strips 14, 15.

[0056] As in Figure 3C As shown in , the contours 22 , 23 which are arranged at least substantially on the side 21 of the retaining element 3 facing away from the wiper lip 4 in the assembled state can also be connected to the composite component 2 by means of the retaining strips 14 , 15 , as indicated by the arrows 18 , 18 ′.

[0057] In the present embodiment, the profile bodies 22, 23 are configured as spoilers 24, 25. However, differently configured profile bodies 22, 23 or spoilers 24, 25 can also be assembled and fastened in a corresponding manner.

[0058] As shown in Figure 3D 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 18, 18'.

[0059] 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.

[0060] As shown in Figure 2 the backsheet 6 has recesses 34, 35, 36, which in the present embodiment are each designed at least approximately rectangularly. The recesses 34, 35 are arranged on the outside of the backsheet 6 as outer recesses 34, 35 with respect to the longitudinal extension 5. The recess 36 is arranged on the inside of the backsheet 6 as an inner recess 36 with respect to the longitudinal extension 5, in particular approximately centrally. The recesses 34, 35, 36 are preferably arranged centrally in the backsheet when viewed transversely to the longitudinal extension, and are configured as recesses 34, 35, 36 that are closed on the periphery and completely penetrate the backsheet.

[0061] As shown in Figure 6B a recess 34 is provided at the end 41 of the backsheet 6 when viewed along the longitudinal extension 5. Correspondingly, a recess 35 is provided at the end 42 of the backsheet 6 when viewed along the longitudinal extension 5. The explanations regarding the recess 34 and the associated features and advantages correspondingly apply to the recess 35.

[0062] In a feasible design, correspondingly designed recesses 34, 35, in particular at least approximately rectangular recesses 34, 35, are provided at the ends 41, 42 of the backsheet 6 when viewed along the longitudinal extension 5. The end caps 30, 31 are each connected to the backsheet 6 by locking elements 37, 38 that are inserted into the respective recesses 34, 35.

[0063] Figure 6A It shows how the locking element 37, which is configured as a locking rod 37 with a locking projection 45, is lifted according to the arrow 46 during pushing. Figure 6B The locked-in state is then shown.

[0064] Figure 7B and Figure 7CShows a centered recess 36 in the middle 44 disposed between the ends 41, 42 of the backsheet 6 as viewed along the longitudinal extension 5, and in particular at least approximately disposed between the ends 41, 42 of the backsheet 6 as viewed along the longitudinal extension 5. The recess is preferably configured at least approximately rectangularly.

[0065] The recess 36 is for fastening a fastening adapter 20, which is for fastening to the wiper arm. In the present embodiment, there are two locking elements 39, 40 embedded in the recess 36 to connect the fastening adapter 20 to the backsheet 6.

[0066] Figure 7A Shows the displacement of the fastening adapter 20, wherein the locking elements 39, 40 configured as locking rods 39, 40 are adjusted according to the arrow 47 to enable assembly.

[0067] Therefore, the following design is feasible, in which the backsheet 6 has recesses 34, 35, 36, and at least one additional component 20, 30, 31 is connected to the backsheet 6 by means of at least one locking element 37, 38, 39, 40 embedded in the recesses 34, 35, 36.

[0068] Figure 8A and Figure 8B Show the details on the end side of the wiper device 1 in an open and partially cut-away view for explaining the limitation of the movement between the combined component 2 and the backsheet 6. Here Figure 8A Shows a feasible design. Figure 8B Shows a modified design.

[0069] The combined component 2 can be displaced relative to the backsheet 6 along the longitudinal extension 5 in a limited manner by a mechanical stop. The displacement of the combined component 2 along the longitudinal extension 5 relative to the backsheet 6 can be Figure 8A defined as shown in Figure 8B by at least one end cap 30, 31, and / or can be

[0070] Figure 9A and Figure 9B Shows schematically the wiper device 1 in a design without a spoiler according to the second embodiment, wherein Figure 9B shows the details at the end cap 30 in a spatial view.

In addition, the 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 21 facing away from the wiper lip 4.
