[0003] Fastening arrangement for detachably attaching a wiper element to a wiper holding device for a windshield wiper device of a motor vehicle and motor vehicle with such a fastening arrangement

[0004] The invention relates to a fastening arrangement for detachably fastening a wiper element, in particular a wiper blade, to a wiper holding device, in particular to a wiper arm, for a windshield wiper device of a motor vehicle, in particular a commercial vehicle, and to a motor vehicle, in particular a commercial vehicle, with such a fastening arrangement.

[0005] Such a mounting assembly comprises a wiper holder and a wiper element. The wiper element is detachably attached to the wiper holder. A locking element is provided for this purpose, which can be moved between a functional position and a maintenance position. In the maintenance position, the wiper element can be removed from the wiper holder, while removal of the wiper element from the wiper holder is blocked in the functional position. When a motor vehicle equipped with such a mounting assembly is washed with a high-pressure water jet, the locking element may be displaced by the high-pressure water jet, resulting in the wiper element not being, or no longer being, fully attached to the wiper holder.To prevent this, it is known that the wiper retaining device has a stop element and the locking element has a counter-stop element, which interact to prevent the wiper element from unintentionally detaching from the wiper retaining device – in particular, a displacement of the locking element – ​​during operation. The stop element and the counter-stop element are usually concealed from the user, so that the user cannot determine whether they are properly engaged. If they are, the locking element, the stop element, and / or the counter-stop element could be damaged during forced disassembly.

[0006] The invention is therefore based on the objective of providing a fastening arrangement for the detachable fastening of a wiper element, in particular a wiper blade, to a wiper holding device, in particular to a wiper arm, for a Daimler Truck AG 2 Dr. Britta Riege

[0007] 31.10.2025 To create a windscreen wiper device of a motor vehicle, in particular a commercial vehicle, and a motor vehicle, in particular a commercial vehicle, with such a fastening arrangement, wherein the aforementioned disadvantages are reduced, preferably do not occur.

[0008] The problem is solved by providing the present technical teaching, in particular the teaching of the independent claims as well as the preferred embodiments disclosed in the dependent claims and the description.

[0009] The problem is solved in particular by providing a fastening arrangement for the detachable attachment of a wiper element, especially a wiper blade, to a wiper holding device, especially a wiper arm, for a windshield wiper system of a motor vehicle, especially a commercial vehicle. The fastening arrangement includes a wiper holding device, wherein a first end of the wiper holding device has a fastening element for a wiper element. A locking element is mounted and configured at the first end of the wiper holding device to be displaced along a displacement direction between a functional position and a maintenance position.In this arrangement, the locking element projects beyond the first end along the displacement direction and has a stop element oriented transversely, in particular orthogonally, to the displacement direction and spaced apart from the first end along the displacement direction. Furthermore, the fastening arrangement includes a wiper element, with a counter-fastening element mounted on the wiper element. The wiper element is arranged and configured to pivot relative to the counter-fastening element between a blocking position and a release position. A counter-stop element projects transversely, in particular orthogonally, to a longitudinal extent of the wiper element from the wiper element. The fastening element and the counter-fastening element are configured and interact to define, in particular to position, a relative position of the counter-fastening element to the fastening element in an inserted position.In particular, the wiper element is detachably attached to the mounting element of the wiper holding device by means of the counter-fastening element, in particular held, in particular positively locked, in particular inserted, in particular positively locked. The locking element is designed and arranged to prevent the counter-fastening element from being removed from the inserted position, in particular along an insertion axis, in the functional position, and to release the counter-fastening element from being removed from the inserted position, in particular from the mounting element, in the maintenance position. The stop element and the counter-fastening element are described below. Daimler Truck AG 3 Dr. Britta Riege.

[0010] 31.10.2025 Stop element designed and working together to block a movement of the locking element between the functional position and the maintenance position in the blocking position and to release a movement of the locking element between the functional position and the maintenance position in the release position.

[0011] The wiper element is particularly securely attached to the wiper holder when the locking element is in the operating position. Due to the stop element being positioned further away from the first end, it is easy for the user to see whether the locking element is currently blocked by the counter-stop. If so, the user can pivot the wiper element into the release position and move the locking element into the maintenance position without applying significant force. This prevents damage to the stop and counter-stop. Once the locking element is in the maintenance position, the user can remove the wiper element from the wiper holder by sliding it away from the holder along its insertion axis.In this process, the counter-fastening element is removed from the fastening element and, in particular, taken out of the inserted position.

[0012] In one embodiment, the wiper holding device extends from its first end along a longitudinal dimension to a second end, the second end being designed and configured to be connected to a drive device of the windshield wiper assembly. In particular, the direction of displacement and the longitudinal dimension of the device are oriented parallel, and especially coincidentally, to each other, at least in a section of the wiper holding device containing the fastening element.In the context of this technical teaching, an end, selected from the first end and the second end, is understood to be, in particular, an end section of the wiper holding device, selected from a first end section and a second end section, which extends from an end surface, selected from a first end surface associated with the first end section and a second end surface associated with the second end section, to, in particular, the other end section, selected from the second end section and the first end section. In particular, the stop element is spaced from the first end section, in particular the first end surface, along the displacement direction, in particular from the functional position to the maintenance position. In particular, the displacement direction is oriented transversely, in particular orthogonally, to the first end surface. Daimler Truck AG 4 Dr. Britta Riege.

[0013] 31.10.2025

[0014] In the context of this technical teaching, a functional position is understood to be, in particular, a relative position of the locking element to the wiper holder in which the wiper element is attached to the wiper holder in the inserted position; in particular, a windshield wiper device that has the fastening arrangement is functional. In the context of this technical teaching, a maintenance position is understood to be, in particular, a relative position of the locking element to the wiper holder in which the wiper element is detached from the wiper holder in the inserted position, in particular not attached to the wiper holder; in particular, a windshield wiper device that has the fastening arrangement can be serviced, in particular the wiper element can be replaced, and in particular, is not functional.

[0015] In one embodiment, the wiper element is arranged and configured to pivot about a pivot axis oriented transversely, and in particular orthogonally, to a longitudinal extent of the wiper element relative to the counter-mounting element. In particular, the pivot axis is oriented transversely, and in particular orthogonally, to the longitudinal extent of the device. In the context of this technical teaching, a "blocking position" is understood to be, in particular, a relative pivot position of the wiper element to the counter-mounting element that occurs during normal operation of a windshield wiper device comprising the mounting arrangement, especially during windshield wiping. In particular, the wiper element rests against a windshield that is associated with the windshield wiper device and that is wiped by the wiper element.In the context of this technical teaching, a release position is understood to be, in particular, a relative pivot position of the wiper element with respect to the counter-mounting element, which the wiper element cannot reach independently during normal operation of the windshield wiper device. Specifically, the wiper element can only pivot into the release position when it is not in contact with the windshield, i.e., when the wiper retaining device is folded away from the windshield. This ensures that the wiper element does not unintentionally pivot into the release position during operation of the windshield wiper device. In one embodiment, the counter-stop element is made of a material with a lower strength than the stop element.This advantageously ensures that in the event of an unintentional displacement of the locking element, particularly into the maintenance position, when the stop element is blocked by the counter-stop element, only the counter-stop element is damaged first, and in particular, breaks. Since the counter-stop element is manufactured by Daimler Truck AG, Dr. Britta Riege.

[0016] If the wiper element protrudes on 31.10.2025, it is advantageously replaced along with the wiper element when the wiper element is replaced, so that damage to the counter-stop element during disassembly has no effect on the functionality of the fastening arrangement if an undamaged wiper element with an undamaged counter-stop element is subsequently attached to the wiper holding device.

[0017] In one embodiment, the counter-stop element projects transversely from the wiper element in the direction of displacement. In particular, the counter-stop element is spaced apart from the counter-fastening element along the longitudinal extent of the element. Specifically, the counter-stop element is spaced apart from the first end section, especially the first end face, along the longitudinal extent of the element when the counter-fastening element is in the inserted position.

[0018] In one embodiment, the relative position of the counter-fastening element to the fastening element is determined by the counter-fastening element and the fastening element being positively engaged, such that, in particular, two translational degrees of freedom of the counter-fastening element relative to the fastening element are blocked in both directions, and a further translational degree of freedom is blocked only in a first direction. Specifically, in the functional position, the locking element blocks a second direction of the further translational degree of freedom of the counter-fastening element, thus defining a position of the counter-fastening element relative to the fastening element. In particular, the counter-fastening element is inserted into the fastening element, especially in a positive-locking manner, in the inserted position.

[0019] According to a further development of the invention, the fastening element has at least one fastening recess, wherein the counter-fastening element has at least one fastening projection. In the inserted position, one fastening projection of the at least one fastening projection engages in a fastening recess of the at least one fastening recess.

[0020] This design offers the advantage of particularly simple mounting of the wiper element to the wiper holder, while simultaneously ensuring that the wiper element and the wiper holder are arranged with exceptional precision relative to each other by means of the mounting recess and the mounting protrusion. In one embodiment, the at least one mounting recess is open in a direction parallel to the insertion axis, particularly in the direction of the wiper element. Specifically, the at least one mounting recess is open on three sides by means of the Daimler Truck AG 6 Dr. Britta Riege

[0021] 31.10.2025 The fastening element is limited and open on a fourth side, particularly in the direction of the wiper element. In particular, the fastening recess on the fourth side is not limited by the fastening element. In particular, the fastening element has, specifically, exactly four fastening recesses. In particular, the fastening element is formed by means of the wiper retaining device. In one embodiment, the counter-fastening element is partially box-shaped. In one embodiment, the at least one fastening projection extends transversely, specifically orthogonally, to the longitudinal extent of the element from the counter-fastening element. In particular, the counter-fastening element has, specifically, exactly four fastening projections.

[0022] According to a further development of the invention, the locking element has at least one functional projection and at least one maintenance recess. In the maintenance position, a maintenance recess of the at least one maintenance recess and a fastening recess of the at least one fastening recess are aligned, so that a fastening projection of the at least one fastening projection can be inserted into and removed from the fastening recess. Furthermore, in the functional position, a functional projection of the at least one functional projection and the fastening recess are aligned, so that insertion of the fastening projection into the fastening recess and removal of the fastening projection from the fastening recess are blocked.

[0023] This allows for particularly easy removal and attachment of the wiper element to the wiper holder. In one embodiment, the at least one functional projection is oriented transversely, and in particular orthogonally, to the direction of displacement. Specifically, the at least one functional projection extends transversely, and in particular orthogonally, from a section of the locking element. In one embodiment, the locking element has, in particular, exactly four functional projections. Specifically, the locking element has, in particular, exactly four maintenance recesses. In one embodiment, the mounting recess on the fourth side is limited by the functional projection when the locking element is moved into the functional position.

[0024] According to a further development of the invention, a functional protrusion of the at least one functional protrusion and a maintenance recess of the at least one maintenance recess are arranged one behind the other along the displacement direction, in particular such that their relative position to a fastening recess of the at least Daimler Truck AG 7 Dr. Britta Riege

[0025] 31.10.2025 a fastening recess can be changed by means of a relocation of the locking element, in particular between the functional position and the maintenance position.

[0026] Advantageously, this allows the wiper element to be selectively detached from or attached to the wiper holding device by repositioning the locking element. In one embodiment, two functional protrusions and two maintenance recesses are arranged alternately one behind the other along the direction of repositioning. In particular, a functional protrusion and a maintenance recess form a protrusion-recess pair. Specifically, the locking element has a total of four protrusion-recess pairs, with two first protrusion-recess pairs arranged on a first side of the locking element, and two second protrusion-recess pairs arranged on a second side of the locking element opposite the first side, transverse to the direction of repositioning.

[0027] According to a further development of the invention, the locking element is formed in one piece, in particular of a single material, with the formation of at least one functional protrusion and at least one maintenance recess.

[0028] The locking element is advantageously cost-effective to manufacture. In one embodiment, the locking element is manufactured using an injection molding process, in particular a plastic injection molding process. In another embodiment, the locking element is made of or consists of a plastic.

[0029] According to a further development of the invention, the fastening element comprises a first wall, a second wall spaced apart from the first wall and, in particular, parallel to the first wall, and a third wall oriented transversely, in particular orthogonally, to the first wall and connecting the first wall and the second wall. Here, the first wall, the second wall, and the third wall define a receiving space, in particular facing the wiper element, into which the counter-fastening element is inserted in the inserted position.

[0030] The fastening element is advantageously simple in design, while simultaneously ensuring secure positioning of the counter-fastening element. In one embodiment, the first wall, the second wall, and the third wall form a U-shaped profile, which is oriented transversely to the direction of displacement. Daimler Truck AG 8 Dr. Britta Riege

[0031] 31.10.2025 Wiper holding device in the first end section forming the first wall, the second wall and the third wall, in particular in at least one circumferential direction encompassing the displacement direction, bent.

[0032] According to further training, the first wall and / or the second wall each have a fastening recess or at least one fastening recess.

[0033] Advantageously, the mounting recess is formed directly by means of the wiper holder, in particular by means of the first end section. This eliminates the need for additional elements. In one embodiment, the first wall has two mounting recesses, which are spaced apart from each other, particularly along the direction of displacement. In particular, the second wall has two mounting recesses, which are spaced apart from each other, particularly along the direction of displacement.

[0034] According to a further development of the invention, the wiper element comprises a wiper blade carrier and a wiper blade, wherein the wiper blade is attached to the wiper blade carrier.

[0035] In this design, the counter-fastening element is pivotally mounted on the wiper blade carrier. Alternatively or additionally, the counter-stop element is formed by means of the wiper blade carrier.

[0036] The advantages of this mounting arrangement are also advantageously realized in a wiper element whose wiper blade carrier is designed as a bracket frame. In one embodiment, the wiper blade carrier has a pivot axis, with the opposing mounting element being pivotably mounted on the pivot axis about this axis.

[0037] According to an alternative embodiment of the invention, the wiper element comprises a wiper blade carrier and a wiper blade, wherein the wiper blade is attached to the wiper blade carrier, and an intermediate support is attached to the wiper blade carrier. The counter-fastening element is pivotably mounted on the intermediate support. Alternatively or additionally, the counter-stop element is formed by means of the intermediate support.

[0038] The advantages of this mounting arrangement are also advantageously realized in a wiper element whose wiper blade carrier is designed as a spring element. In one embodiment, the intermediate carrier has a pivot axis, with the opposing mounting element being pivotably mounted on the pivot axis about this axis. Daimler Truck AG 9 Dr. Britta Riege

[0039] 31.10.2025 According to a further development of the invention, the counter-stop element is spaced further from the first end, particularly along the displacement direction, than the stop element when the counter-fastening element is in the inserted position and the locking element is in the functional position. Furthermore, the stop element is spaced further from the first end, particularly along the displacement direction, than the counter-stop element when the counter-fastening element is in the inserted position and the locking element is in the maintenance position.

[0040] It is advantageous for the user to easily recognize whether the locking element is in the operating or maintenance position. Thus, the user can determine at a glance whether the wiper element is attached to the wiper holder, and in particular secured, or not. In one embodiment, the counter-stop element is concealed by the stop element, and thus hidden from the user, when the locking element is in the maintenance position. In particular, the wiper element is not attached to the wiper holder in this case. In another embodiment, the counter-stop element is free from the stop element, and thus not concealed, and thus visible to the user, when the locking element is in the operating position. In this case, the wiper element is attached to the wiper holder.

[0041] The problem is also solved by creating a motor vehicle, in particular a commercial vehicle, with a fastening arrangement according to the invention or a fastening arrangement according to one or more of the embodiments described above. In connection with the motor vehicle, in particular a commercial vehicle, the advantages that have already been explained in connection with the fastening arrangement become particularly apparent.

[0042] The invention will be explained in more detail below with reference to the drawing. The drawing shows:

[0049] The fastening arrangement 1 has a wiper holding device 5, wherein a first end

[0050] 7.1 The wiper holding device 5 has a fastening element 9.1 (see Figure 2) for a wiper element 3. A locking element 11 is mounted at the first end 7.1 of the wiper holding device 5 and is designed to be displaced along a displacement direction 13, indicated by a double arrow, between a functional position 15 and a maintenance position 17. The locking element 11 projects beyond the first end 7.1 along the displacement direction 13 and has a stop element 19.1 oriented transversely, in particular orthogonally, to the displacement direction 13 and spaced apart from the first end 7.1 along the displacement direction 13. Furthermore, the fastening arrangement 1 has a wiper element 3, with a counter-fastening element 9.2 (see Figure 3) being mounted on the wiper element 3. Here, the wiper element 3 is arranged and designed to be relative to the counter-fastening element 9.2 - represented by a double arrow A - is pivoted between a blocking position 21 and a release position 23. A counter-stop element 19.2 projects transversely, in particular orthogonally, to a longitudinal extent of the wiper element 3 from the wiper element 3. The fastening element 9.1 and the counter-fastening element 9.2 are designed and interact to define a relative position of the counter-fastening element 9.2 to the fastening element 9.1 in an inserted position. The locking element 11 is designed and arranged to prevent the counter-fastening element 9.2 from being removed from the inserted position, in particular along a dashed insertion axis 25, and from the fastening element 9.1, in the functional position 15, and to prevent its removal in the maintenance position 17.
