This allows for easy assembly and avoids complex fastening solutions.

[0036] Furthermore, the following features and advantages can be achieved depending on the design and application.

[0037] A windshield wiper can be provided that allows easy replacement of the wiper lip. This allows for a design that allows only a portion of the wiper to be replaced in order to replace the wiper lip. In one possible design, only the wiper lip can be replaced. In other possible designs, the wiper lip can be replaced together with other components of the wiper, in particular structural components. This makes it possible, in particular, to achieve easy replacement that can be conveniently performed by a user, in particular a vehicle driver.

[0038] The windshield wiper can be designed in such a way that it can be at least partially disassembled in an easy manner. It is also possible to completely disassemble the windshield wiper. The windshield wiper can be designed in such a way that it can also be disassembled by the user, without having to visit a repair shop.

[0039] In an advantageous embodiment, the wiper element and / or the fastening adapter fastened to at least one wiper blade are firmly connected to one another, so that these components cannot be detached from one another.

[0040] The windshield wiper can be designed in such a way that it is mounted on a wiper arm or the like as a whole and can be removed from the wiper arm or the like again. This can make it easier to replace the wiper lip.

[0041] In a windshield wiper, at least one wiper blade can be accessible at its longitudinal sides at least substantially over its entire longitudinal extension in order to enable fastening to a structural component.

[0042] The structural component can include other components of the wiper at its longitudinal side. In particular, the structural component can include end caps and other end caps at its longitudinal side. Here, the structural component can extend in the longitudinal direction along the longitudinal extension.

[0043] Since the structural component is connected to one or more back sheets at the outer longitudinal sides, a particularly rigid design can be achieved. This allows for a particularly rigid fastening of the wiper lip to the wiper, and therefore to the fastening adapter. This allows for high wiping efficiency.

[0044] The wiper can include a fastening adapter, a first wiper element, a second wiper element, a first end cap, a second end cap, a back sheet, and a structural member. The first wiper element and the second wiper element can each have a deflector. The first end cap and the second end cap can each have a deflector.

[0045] The fastening adapter can be plugged onto the back sheet between the first wiper element and the second wiper element. The fastening adapter can be arranged at least approximately centrally on the back sheet or between the first wiper element and the second wiper element. To this end, the first wiper element and the second wiper element can be designed to have the same length along their longitudinal extension. In particular, the first wiper element and the second wiper element can be designed identically.

[0046] Accordingly, the fastening adapter can also be arranged at least approximately centrally on a plurality of back panes.

[0047] Wiper element and / or fastening adapter can be inserted on the back sheet at least approximately perpendicular to longitudinal extension.In addition, end cap can be inserted on the end of back sheet.

[0048] The fastening adapter and / or the wiper element can be non-detachably connected to at least one wiper blade. In particular, welding, hot pressing, etc. can be used to connect the components to one another. This connection can be implemented as an additional option to a form-fit connection, resulting in a gap-free and / or highly load-bearing connection.

[0049] The fastening adapter can have at least one fastening projection, preferably approximately four fastening projections, in particular exactly four fastening projections. These fastening projections can be inserted into a corresponding number of fastening recesses, in particular fastening holes. In particular, the components can be additionally connected to one another by welding, hot pressing, etc. This allows for a non-detachable connection.

[0050] In a corresponding manner, the wiper element can be connected to more than one fastening lug by welding, heat pressing or the like.

[0051] The windshield wiper can be designed as a flat-rod wiper. One or more backing plates can be provided. Furthermore, deflectors can be provided on components of the windshield wiper. These deflectors can be provided on the wiper element and / or on the structural component. However, designs without deflectors are also possible.

[0052] The end caps can each have a guide rail or a guide rail section on the longitudinal sides, which, when the components are arranged one after the other along the longitudinal extension, join to the end of the corresponding guide rail section of at least one back sheet. The guide rail or guide rail section then forms a guide rail onto which the structural components can be placed or pushed on both sides.

[0053] This design can be realized in this way that the structural component can be disassembled in an easy manner and can also be reassembled if necessary. In the application case related thereto, this can accordingly realize the easy replacement of the structural component, in particular together with the wiper lip.

[0054] In the assembled state, the structural member can encompass the back sheet or back sheets together with the end pieces at the longitudinal sides at least substantially over its entire extension in the longitudinal direction.

[0055] At least one back sheet can be inserted into the structural component together with the components mounted thereon, in particular the fastening adapter, optionally the wiper element and the end piece, thereby enabling easy assembly.

[0056] The windshield wiper can be easily disassembled (disassembled) and reassembled (assembled). A locking mechanism can be used for this purpose. In a preferred embodiment, a locking element, in particular a latching element, is provided on at least one end cap, which engages in a recess in the structural component. This allows for easy release of the locking portion, allowing, for example, a user, in particular a vehicle driver, to easily disassemble the structural component. The locking element can be actuated, for example, by pressing. In a modified embodiment, the locking element can also be actuated by pulling. Other possible solutions for actuating the locking element are also conceivable. The locking element can also be designed as a sliding part, for example.

[0057] In a design in which only one of the two end caps has a locking element, the end cap with the locking element can be arranged at one end or the other end of the wiper. In a wiper that is guided on the windshield according to the rotational movement of the wiper arm, the end cap with the locking element can be located on the inside or outside, or on the outer or inner ring.

[0058] In the case of a latching mechanism, automatic latching is achieved during assembly of the structural components when the components are in their predetermined relative positions. The latching mechanism allows the latching element to snap into place in the recess. This snapping can be associated with an acoustic feedback to the user. This allows the user to intuitively reassemble the wiper after replacing the wiper lip.

[0059] The latch element is preferably in a preload during the joining process or when assembling, until it is then snapped into the recess. Then, the replacement of the wiper lip can be performed again by pressing the latch element again.

[0060] In a modified embodiment, the latching element can also be pulled to release the latch. In particular, the latching element can be designed so that the user pulls on a button of the latching element to release the latch. In this embodiment, a preload is preferably applied to the latching element during assembly or installation until the latching element engages the recess.

[0061] The latch can then be released in particular by the user moving the latching element out of the recess of the structural component by pressing or pulling and thereby, for example, bending the tab, so that the latching element is under preload, which is important for assembly.

[0062] The recess for the stop can be arranged on the structural component in such a way that it points inwards.

[0063] The structural component and the wiper lip can perform two different functions and be designed to suit them. The wiper lip can be made of a soft material that is suitable for cleaning the window pane, in particular the windshield. The structural component can be made of a material that matches the desired mechanical stability and rigidity. In particular, the structural component can be designed as a rigid structural component through material selection. This allows the mechanical stability of the wiper to be optimized.

[0064] The structural component and the wiper lip are preferably designed as coextruded components (coextruded components). However, in a modified embodiment, the wiper lip can also be connected to the structural component in another manner. In one possible embodiment, the wiper lip can be connected to the structural component in a form-fitting manner. In particular, it is possible to remove the wiper lip from the structural component and thus replace only the wiper lip.

[0065] The structural component can be configured with one or more deflectors. Depending on the design, the deflectors and the structural component can also be co-extruded. However, modified designs are also possible. For example, the deflectors can also be clipped onto the structural component or connected to it in some other way. This allows, if necessary, to standardize the production of the structural component, particularly within the framework of a modular construction system. This also allows, for example, the assembly of the structural component without deflectors when a windshield wiper is to be manufactured without deflectors. BRIEF DESCRIPTION OF THE DRAWINGS
