The invention relates to a wiper blade device having at least one wiper blade adapter having at least one connecting element and at least one main body, which is provided for coupling to at least one wiper blade component, such as a wiper strip, a spring rail and/or a spoiler element, and in particular to the connecting element and for rotatably mounting the connecting element at least partially, preferably at least largely and particularly preferably completely, about a bearing axis relative to the wiper blade component.

It is proposed that the base body is provided for being at least partially elastically deformed, in particular by the connecting element, during the mounting and/or dismounting of the connecting element, in particular during the coupling and/or decoupling of the connecting element. "provided" is to be understood in particular as meaning specially designed and/or equipped. An object is provided for a certain function, in particular, to be understood as meaning that the object fulfills and/or performs this certain function in at least one application and/or operating state. The term "at least predominantly" is to be understood here to mean, in particular, at least 55%, advantageously at least 65%, preferably at least 75%, particularly preferably at least 85%, and particularly advantageously at least 95%.

A "wiper blade device" is to be understood in this connection to mean, in particular, at least one component, in particular a subassembly, of a wiper blade, in particular a windshield wiper blade and advantageously a motor vehicle windshield wiper, and/or a mounting package (structural assembly) for a wiper blade, in particular a windshield wiper blade and advantageously a motor vehicle windshield wiper. In particular, the wiper blade device can also comprise the entire wiper blade and/or the entire mounting packet for the wiper blade.

In addition, a "main body" is to be understood to mean, in particular, an at least partially elastically designed unit which, in the mounted state, has at least one contact area with the wiper blade component and, in particular, with the connecting element and can advantageously be connected in a non-releasable manner to the wiper blade component and/or to the connecting element. The base body in particular has at least one wiper blade fastening element, which is provided in particular for connecting the base body to the wiper blade part, advantageously releasably, and in particular has at least one coupling element, which is provided in particular for connecting the base body to the connecting element, advantageously releasably. The base body is advantageously provided for coupling and/or connecting to a connecting element of a different type and/or of a different design. Furthermore, the base body is particularly preferably constructed in one piece. "integrally" in this context is to be understood in particular to mean at least a material-to-material connection. The material-fit connection can be produced, for example, by a bonding process, an injection molding process, a welding process, a soldering process and/or other processes. Advantageously, integrally should be understood as being formed in one piece. Preferably, the one part is produced from a single blank, a block and/or a cast part, particularly preferably in an extrusion process, in particular a single-component and/or multi-component extrusion process, and/or a die casting process, in particular a single-component and/or multi-component die casting process. "releasable" in this context is to be understood to mean, in particular, a connection between at least two objects which can be established and/or separated, in particular reversibly, advantageously arbitrarily often and without damage, preferably without damage to the objects. "coupled" is to be understood to mean, in particular, a form-fitting and/or force-fitting connection. Furthermore, an "elastic element" is to be understood to mean, in particular, an element, preferably a restoring element, which has at least one partial region and/or at least one portion which can be elastically changed at least in its position by at least 1mm, advantageously by at least 2mm, preferably by at least 5mm and particularly preferably by at least 1cm in the normal operating state and which generates a reaction force which is dependent, in particular, on the change in position and is preferably proportional to the change, which reaction force acts in particular against the change. In particular, the elastic element can be repeatedly deformed, in particular at least 10 times, preferably at least 50 times, in particular without damage, and automatically strives again to return to the basic shape after the deformation. In this connection, the term "elastically deformable" is to be understood in particular to mean that the base shape is at least partially elastically deflected and advantageously has at least one partial region and/or at least one portion which can elastically change its position by at least 1mm, advantageously at least 2mm, preferably at least 5mm and particularly preferably at least 1cm, relative to the initial position, the rest position and/or the reference position. "objects of different types and/or different structures" are to be understood in this connection to mean, in particular, different objects which differ in their structure and/or their fastening function. Preferably, differently standardized (normalized) objects are used here.

Furthermore, a "connecting element" is to be understood to mean, in particular, an element which is designed separately from the base body and which, in particular in the mounted state, has at least one contact region with the wiper arm adapter and/or the wiper arm and which is provided, in particular, for releasably connecting the base body, advantageously with the wiper arm adapter and/or the wiper arm, advantageously in a non-releasable manner. The connecting element is advantageously provided here for coupling and/or connecting with a wiper arm adapter and/or a wiper arm of a different type and/or a different design. The connecting element can in particular be designed in one piece and/or in several parts, in particular in two parts.

The bearing axis is furthermore advantageously arranged at least substantially perpendicularly to an assembly and/or disassembly direction and preferably at least substantially perpendicularly to a wiper blade longitudinal direction and/or a main direction of extension of the main body. Furthermore, the bearing axis is preferably arranged at least substantially parallel to a wiping direction. "wiper blade longitudinal" is to be understood in particular to mean a direction which extends at least substantially parallel to a main direction of extension of the wiper blade. A "main direction of extension" of an object is to be understood to mean, in particular, a direction which is parallel to a smallest, but which also encompasses the longest side and/or flank of the object, in particular of an imaginary, rectangular parallelepiped. The term "at least substantially perpendicular" is intended here to define, in particular, an orientation of a direction relative to a reference direction, wherein the direction and the reference direction, in particular viewed in a plane, enclose an angle of, in particular, between 82 ° and 98 °, advantageously between 85 ° and 95 °, and particularly preferably between 88 ° and 92 °. Furthermore, "at least substantially perpendicular" is to be understood to mean, in particular, an orientation of a direction relative to a reference direction, in particular in a plane, wherein the direction has a deviation relative to the reference direction of, in particular, less than 8 °, advantageously less than 5 °, and particularly advantageously less than 2 °. By a corresponding design of the wiper blade device, in particular the efficiency, in particular the production efficiency, the processing efficiency and/or the cost efficiency, can be improved. Furthermore, flexibility can be advantageously increased. Furthermore, the mounting and/or dismounting process can be advantageously simplified.

Preferably, the base body comprises at least one, in particular elastically deformable coupling element, in particular the coupling element already mentioned above, for coupling with the connecting element, which has a main plane of extension arranged at least substantially perpendicularly to the bearing axis and/or the wiping direction and is provided for being deformed and/or deflected, at least in sections, in particular elastically, during mounting and/or dismounting, and in this case advantageously pivoting about a pivot axis arranged, in particular at least substantially perpendicularly to the bearing axis and/or at least substantially parallel to the longitudinal direction of the wiper blade. The coupling element, in particular in the mounted state, at least partially contacts the connecting element, in particular a side wall of the connecting element, advantageously an inner surface of the side wall, and in particular preferably bears against the connecting element, in particular a side wall of the connecting element, in particular an inner surface of the side wall, in a force-fitting and/or form-fitting manner. Particularly preferably, the coupling element is formed by a coupling wall. A "main plane of extension" of an object is to be understood here to mean, in particular, a plane which runs parallel to a smallest, in particular imaginary, maximum side of the cuboid which also completely surrounds the object, and in particular runs through a center point, in particular a geometric center point. This makes it possible in particular to achieve a particularly simple and/or rapid connection.

An advantageously simple construction can be achieved in particular if the coupling element is provided for being deflected in a direction at least substantially perpendicular to the mounting and/or dismounting direction and/or in a direction at least substantially supporting the axis during mounting and/or dismounting.

It is furthermore proposed that the base body comprises at least one further, in particular elastically deformable coupling element which has a main extension plane arranged at least substantially perpendicularly to the bearing axis and/or to the wiping direction and at least substantially parallel to the main extension plane of the coupling element and is provided for being deformed and/or deflected at least partially, in particular elastically, during mounting and/or dismounting and in this case advantageously pivoting about a pivot axis which is arranged at least substantially perpendicularly to the bearing axis and/or at least substantially parallel to the longitudinal direction of the wiper blade. Advantageously, the coupling element and the further coupling element are arranged opposite one another and/or at a distance from one another. Advantageously, in this case, a recess and/or an air-filled region is arranged between the coupling element and the further coupling element. In particular, the further coupling element at least partially contacts the connecting element in the mounted state, in particular a further side wall of the connecting element opposite to the in particular side wall of the connecting element, in particular an inner surface of the further side wall, and in particular preferably bears against the connecting element, in particular the further side wall of the connecting element, in particular the inner surface of the further side wall, in a force-fitting and/or form-fitting manner. Particularly preferably, the further coupling element is formed by a coupling wall. In particular, a particularly stable and/or robust wiper blade device can thereby be provided.

In one embodiment of the invention, it is proposed that the further coupling element is formed at least substantially mirror-symmetrically to the coupling element, in particular with respect to a central plane, in particular a longitudinal plane of symmetry, which is arranged at least substantially perpendicularly to the bearing axis and/or to the wiping direction. In particular, the term "at least substantially mirror-symmetrical" formation of one object from another object is to be understood to mean that the deviation of the formation of a mirror image of the object with respect to a defined and/or definable mirror plane from the other object is at most 15%, preferably at most 10% and particularly preferably at most 5% by volume. In particular, it is preferred that the further coupling element is at least substantially identically configured to the coupling element, in particular identically configured irrespective of the machining tolerances. This can simplify the processing and/or production, in particular. Furthermore, an advantageously uniform force distribution can be achieved.

A particularly simple and/or quick installation can be achieved if the coupling element and the further coupling element are provided for being moved towards one another during installation and/or removal.

Furthermore, a wiper blade device is proposed, which has at least one wiper blade adapter having at least one connecting element and at least one main body, which is provided for coupling to at least one wiper blade component and in particular to the connecting element and which supports the connecting element at least partially, preferably at least largely and particularly preferably completely, rotatably about a bearing axis relative to the wiper blade component, wherein the main body is designed at least substantially mirror-symmetrically with respect to a center plane, in particular a transverse plane of symmetry, which is arranged at least substantially perpendicularly to a wiper blade longitudinal direction, in particular the wiper blade longitudinal direction already indicated above, and/or to a main direction of extension of the main body. Particularly advantageously, the bearing axis in this case lies in a central plane. The base body is advantageously provided in this case for coupling with the connecting element in at least one first position of the connecting element relative to the base body and in at least one second position of the connecting element relative to the base body, in particular rotated by at least substantially 180 °. In this way, particularly high installation efficiencies can be achieved, in particular because the installation can be carried out in any desired orientation, in particular on both sides.

In a preferred embodiment of the invention, it is proposed that the wiper blade device has at least one further connecting element of a different type and/or in a different design than the connecting element, wherein the base body is provided for rotatably mounting the further connecting element, in particular instead of and in particular not in addition to the connecting element, at least partially about a bearing axis relative to the wiper blade part. In particular, the base body is provided in this case for coupling, in particular selectively, with at least one of the at least two different connecting elements, in particular the connecting element or the further connecting element. In particular, the wiper blade device can also have further connecting elements of different types and/or different designs. In particular, this makes it possible to provide a wiper blade adapter which can be used advantageously flexibly, wherein the main body can advantageously be adapted to different connecting elements, in particular to different requirements and/or designs of the wiper arm and/or of the wiper arm adapter.

In particular, it is conceivable for the base body to be at least partially elastically deformed by a side wall, in particular an inner wall, of the connecting element during the mounting and/or dismounting of the connecting element. The connecting element preferably has at least one force transmission element, which is provided to apply at least one deflection force to the main body and in particular to the coupling element and/or the further coupling element during the assembly and/or disassembly and thereby to at least partially elastically deform the main body. Advantageously, the deflection force is in this case directed at least partially and preferably at least predominantly in the direction of the bearing axis. Particularly advantageously, the force transmission element is arranged on a side wall and/or the other side wall of the connecting element, in particular on an inner surface of the side wall and/or the other side wall. Particularly preferably, the connecting element has at least two, advantageously exactly two, preferably at least substantially identically configured force transmission elements to one another, wherein advantageously a further force transmission element is arranged on a side wall and/or a further side wall of the connecting element opposite the side wall and/or the further side wall, in particular on an inner surface of the side wall and/or on an inner surface of the further side wall. In particular, this makes it possible to achieve a favorable force transmission and/or force action on the base body.

A particularly simple and/or uniform deformation and/or deflection of the base body can be achieved in particular if the force transmission elements are at least substantially strip-shaped. The main direction of extension of the force transmission element is advantageously arranged here at least substantially parallel to the mounting and/or dismounting direction and/or at least substantially perpendicular to the bearing axis. An "at least substantially continuous strip-shaped" object is to be understood in this case to mean, in particular, an object whose deviation from a reference object continuous to the strip-shaped object is at most 15%, preferably at most 10% and particularly preferably at most 5% by volume. In particular, the coupling element and/or the further coupling element in this case preferably has at least one guide element, which is provided in particular for guiding the force transmission element at least in sections, in particular at least during the removal process, and in this case advantageously comprises at least one ramp section. Advantageously, the force transmission element is provided in this case for interacting with the ramp section for deflecting the coupling element and/or the further coupling element.

The invention further relates to a method for mounting and/or demounting a wiper blade device having at least one wiper blade adapter having at least one connecting element and at least one main body, which is provided for coupling to at least one wiper blade component, for example a wiper strip, a spring bar and/or a spoiler element, and in particular to the connecting element and for rotatably supporting the connecting element at least partially, preferably at least largely and particularly preferably completely, about a bearing axis relative to the wiper blade component.

It is proposed that the base body is at least partially elastically deformed, in particular by the connecting element, during the mounting and/or dismounting of the connecting element, in particular during the coupling and/or decoupling. This may improve efficiency, in particular manufacturing efficiency, processing efficiency and/or cost efficiency, and/or increase flexibility.

The wiper blade device should not be limited to the above-described applications and embodiments. In particular, the wiper blade device can have a number which differs from the number of individual elements, components and units specified here in order to meet the operating mode described here.

58, 60 are arranged on the side of coupling element 20 facing away from the other coupling element 22. The

guide elements

58, 60 are designed mirror-symmetrically with respect to the transverse plane of symmetry 49. The

guide elements

58, 60 are at least substantially L-shaped. The

guide elements

58, 60 extend in the wiper blade longitudinal direction from the carrier element 52. Furthermore, each of the

guide elements

58, 60 has a

ramp section

59, 61. The

ramp sections

59, 61 enclose an acute angle with the base surface of the coupling element 20.

The base body 16 is now provided for being at least partially deformed and/or deflected during the mounting and dismounting of the connecting element 10, in particular of the second connecting element part 44, in particular by the connecting element 10, in particular of the second connecting element part 44. For this purpose, the base body 16 is at least partially elastically formed. In the present case, the

coupling elements

20, 22 are elastically designed and in particular provided for being at least partially deformed and/or deflected during the mounting and dismounting process. In this case, the

coupling elements

20, 22 are provided for being moved towards one another during the mounting and dismounting process. Furthermore, the

coupling elements

20, 22 are provided for being deflected in a direction at least substantially perpendicular to the mounting and/or dismounting direction during mounting and dismounting. Coupling

elements

20, 22 are thereby at least partially elastically deformed and/or deflected by the deflecting force of connecting element 10, in particular of second connecting element section 44. Coupling

elements

20, 22 are each pivoted about a

pivot axis

62, 64 by a deflecting force of connecting element 10, in particular of second connecting element part 44. The pivot axes 62, 64 are arranged parallel to each other. The pivot axes 62, 64 are arranged parallel to the wiper blade longitudinal direction. By means of this deflection force, at least a part of the coupling element 20 and the further coupling element 22 changes their position by at least 1cm relative to an initial position.

For applying the deflecting force, the connecting element 10 has at least one force transmission element 24, 26 (see in particular fig. 4). In the present case, the second connecting element section 44 has the at least one force transmission element 24, 26. The second connecting element part 44 has two force transmission elements 24, 26. One of the force transmitting elements 24, 26 is arranged on the inner surface of the side wall of the second connecting element portion 44. The force transmission element 24 is in this case assigned to the coupling element 20. The other force-transmitting element 26 of the force-transmitting elements 24, 26 is arranged on the inner surface of the other side wall of the second connecting element portion 44. The other force transmission element 26 is assigned to coupling element 22 in the present case. The force transmission elements 24, 26 are designed mirror-symmetrically with respect to the longitudinal plane of symmetry 48. Furthermore, the force transmission elements 24, 26 are at least substantially of strip-shaped design. The respective main direction of extension of the force transmission elements 24, 26 is arranged parallel to the mounting and/or dismounting direction. Furthermore, the respective main direction of extension of the force transmission elements 24, 26 is arranged perpendicular to the bearing axis 18. The force transmission elements 24, 26 are provided for interacting with a corresponding base surface of the

coupling elements

20, 22 during the assembly process in order to deflect the

coupling elements

20, 22. Furthermore, the force transmission elements 24, 26 are provided for interacting with a

corresponding ramp section

59, 61 for deflecting the

coupling elements

20, 22 during the removal process and in this case in particular for decoupling the connection element 10 from the main body 16. In the present case, the base surfaces of the

coupling elements

20, 22 are provided as continuous stops for the respective force transmission elements 24, 26. The side walls also serve as lateral guides, in particular as lateral positive guides. Alternatively, it is also conceivable to dispense entirely with, in particular, an additional force transmission element. The force transmission element can in this case be realized, for example, by a side wall of the connecting element, in particular the inner surface of the side wall.

Fig. 5 shows the base body 16 together with the second connecting element part 44 in the mounted state, wherein in particular the second connecting element part 44, in particular for the purpose of illustrating the interaction of the force transmission elements 24, 26 with the

ramp sections

59, 61, is shown at least partially transparent. In particular, the ramp section of second coupling element 22, with which the further force transmission element 26 interacts, is not explicitly shown in this case.

In the following, the connection element 10, in this case in particular the second connection element section 44, is first described, for example, with respect to the mounting process with the base body 16 and the connection element 10, in this case in particular the removal process of the second connection element section 44, from the base body 16 is described next. The underlying process described below is not limited to the second connecting element part 44, but can be transferred analogously to the connecting element 10 and the further connecting

elements

12, 14.

In an initial position of the mounting process, the second connecting element part 44 is arranged above the base body 16. Fig. 6a shows the initial position of the base body 16. During the mounting process, the second connecting element part 44 is guided in a linear movement in the direction of the base body. The linear movement is carried out in a mounting direction, which is arranged perpendicular to the bearing axis 18. First the second connecting element portion 44 is moved by the end user onto the base body 16. In this case, the force transmission elements 24, 26 are in contact with the

coupling elements

20, 22. The force transmission elements 24, 26 then exert a deflecting force on the

coupling elements

20, 22. A movement of the second connecting element part 44 in the installation direction thereby causes a deflection of the

coupling elements

20, 22. During deflection,

coupling elements

20, 22 move toward one another. Fig. 6b shows the deflected position of the substrate 16. The

coupling elements

20, 22 are pivoted about pivot axes 62, 64. In this case, at least one part of coupling element 20 and further coupling element 22 changes their position by at least 1cm relative to an initial position. The required deflection force depends here primarily on the material used for

coupling elements

20, 22 and/or the material thickness of

coupling elements

20, 22. Subsequently, the

coupling elements

20, 22 are moved back elastically into their initial position. In the installed state, the support element 52 engages, in particular in a form-fitting manner, into a support element 53 of the connecting element 10 corresponding to the support element 52, whereby a form-fitting coupling is first of all obtained. In this case, the substrate 16 is again in its initial position (see fig. 6 a).

During disassembly, the second connecting element portion 44 is released from the base body 16. The end user lifts the second connecting element part 44, in particular from one side. For the purpose of removal, the end user applies the lifting force to a lifting region of the second connecting element part 44, which is arranged at a free end of the second connecting element part 44. The raised region is in this case arranged on the side of the second connecting element part 44 facing away from the force transmission elements 24, 26. The lifting force extends substantially parallel to the mounting and/or dismounting direction. During the disassembly process, in particular during the lifting of the second connecting element part 44, the second connecting element part 44 is rotated about the bearing axis 18. In this case, the substrate is initially in its initial position (see fig. 6 a). Furthermore, the force transmission elements 24, 26 are at least partially guided by the

guide elements

58, 60. The force transmission elements 24, 26 thus move essentially first up to the

ramp sections

59, 61. The force transmission elements 24, 26 then continue their movement via the

ramp sections

59, 61. By the interaction of the force transmission elements 24, 26 with the

ramp sections

59, 61, the

coupling elements

20, 22 are elastically deflected. During deflection, the

coupling elements

20, 22 are moved towards each other. Fig. 6b shows a deflected position of the base body 16. The form-fitting coupling between the second connecting element part 44 and the base body 16 is released by the elastically deflected

coupling elements

20, 22. The second connecting element part 44 is released, in particular detached without destruction, from the main body 16 as a result of the lifting in the lifting region by the interaction between the force transmission elements 24, 26 and the

ramp sections

59, 61. During the removal process, the second connecting element part 44 is thus released from the base body 16 by leverage.
