[0003] Trim for a motor vehicle, method for removing trim, fastening device and motor vehicle

[0004] The invention relates to a fairing for a motor vehicle comprising a fairing element and a fairing support arranged in a service position on a vehicle structure, which serves in particular to hold the fairing element, according to claim 1. Furthermore, the invention relates to a method for dismantling a fairing according to claim 8. The invention also relates to a corresponding fastening device and a corresponding motor vehicle according to claims 9 and 10.

[0005] From an ecological perspective, it makes sense to recycle a large proportion of the materials used in motor vehicles. Furthermore, there are frequently updated guidelines for vehicle disposal that stipulate minimum recycling requirements. For proper recycling, disassembly, for example by removing the interior trim, such as the door panel, from the door frame, is advisable in order to separate the relevant raw materials. The faster the disassembly process, the more economically viable the recycling can be.

[0006] For easy installation, clips are used to attach door panels, meaning the same installation and removal direction applies to both the door panel and the body. Additionally, screws are used. For crash-tested door panels, current technology requires screwing the panel to the body shell at multiple points to withstand high tensile loads in the direction of installation and thus the clips. However, numerous screws make removal time-consuming, or require considerable force for destructive removal.

[0007] KR 1020240146835 A discloses a device that allows for the easy removal of a locking element. Furthermore, EP 2358564 B1 discloses a device for attaching a vehicle interior trim panel to a trim support. 24-3272 PIF

[0008] 2

[0009] The object of the present invention is therefore to provide a fairing, a method for its disassembly, as well as a corresponding fastening device and a motor vehicle, by which both a crash design and disassembly are particularly advantageous.

[0010] A first aspect of the invention relates to a fairing for a motor vehicle comprising a fairing element, a fairing carrier arranged in a service position on a vehicle structure of the motor vehicle, and a fastening device comprising a locking element and a corresponding bolt element, wherein the locking element has a base body and a clamping opening extending through it and provided with clamping elements, which is designed to receive the bolt element along a mounting direction and in which the bolt element can be clipped in a mounting position by being inserted or brought into the clamping opening and being fixed or secured there by the clamping elements.

[0011] To ensure that the cladding according to the invention is particularly advantageously removable despite its high strength for crash design, the clamping elements are arranged at the clamping opening in such a way that a discharge opening is formed, and a cover is arranged on the base body on one side of the clamping opening opposite this, and a disassembly direction is specified by the orientation of the discharge opening and the cover, in particular by a connecting line, which is normal or substantially perpendicular to the assembly direction, and the cover is further designed to remove the bolt element from the clamping opening via the discharge opening when a predetermined force is applied to it along the disassembly direction.

[0012] The motor vehicle can be, in particular, a passenger car and / or truck and / or bus. The trim is, in particular, a door trim, so the trim element can be, for example, a door trim panel. The vehicle structure can be, for example, a vehicle door and / or part of a vehicle body or frame. The trim support thus serves to hold, in particular, the trim element in relation to the vehicle structure. In a simple design, the trim support comprises only the bolt element, which can be attached to the vehicle structure, for example, with a positive-locking, force-locking, and / or material-locking connection.24-3272 PIF

[0013] 3

[0014] or is attached. Alternatively, the trim carrier can, for example, include appropriate mounting hardware to attach the bolt element to the vehicle structure. The fastening device thus serves in particular to attach the trim element to the trim carrier and thus to hold the trim element in place relative to the vehicle structure.

[0015] The clamping elements are, for example, made of the same material as the base body and arranged radially such that at least one part projects into the clamping opening, while another part is attached to the base body. The clamping element, particularly the part projecting into the clamping opening, is flexibly deformable, thereby generating the clamping force for clipping. For this purpose, the bolt element may, for example, have corresponding recesses and / or protrusions that correspond to the clamping elements in the assembly position. The bolt element is essentially bolt-shaped and, in particular, designed as a bolt. The assembly direction is, in particular, axial and thus longitudinal to the clamping opening and therefore along the longitudinal extent of the bolt element in its assembly position.Several clamping elements are oriented radially around the clamping opening, with at least two clamping elements, preferably opposing each other, being provided. The flexibility, and thus the force exerted by the clamping elements during clipping, is selected to enable a clipping action advantageous to the crash test design. This makes it difficult to release the clamping element in the opposite direction to the assembly, which would complicate disassembly. To achieve this, the release opening is formed by providing an area around the clamping opening in which no clamping elements are arranged, effectively interrupting the circumferential arrangement of the clamping elements.

[0016] Furthermore, a corresponding recess can be provided on the base body, depending on the length with which the bolt element projects into or through the clamping opening. The exit opening, which is thus arranged radially as opposed to axially, allows the bolt element to be removed from the clamping opening by moving it relative to the clamping opening or the locking element along the disassembly direction. To facilitate disassembly, the invention provides a cover plate which can be used as a handle or attachment point for a suitable tool to exert force on the locking element.

[0017] 4

[0018] to be able to move this advantageously along the disassembly direction relative to the bolt element, so that the bolt element can be removed from the clamping opening via the exit opening, thereby releasing the clip connection in an advantageous and simple way.

[0019] The bolt element is thus released laterally, and therefore essentially normal or perpendicular to the mounting direction, from its mounting position. The cover plate is designed to facilitate this release, providing the necessary force for assembly and disassembly. "Essentially normal or perpendicular" means that a deviation from the vertical of several degrees, up to several tens of degrees, is permitted. This allows for disassembly without requiring the disassembler to adhere perfectly to the disassembly direction, for example, due to a certain amount of play.

[0020] The inventive cladding offers the advantage that a clip system with a hard clipping action can be designed, exhibiting a release force similar to the pull-out force of a screw connection. Furthermore, it provides a means of disassembly by pulling the clip perpendicular to the clip direction from a fastening element, in particular the bolt or bolt element. The force is advantageously applied via a cover plate, which is preferably floating or spring-mounted, and which also allows for visually clean integration into surrounding components.

[0021] In an advantageous embodiment of the invention, at least one of the clamping elements has a stiffening element that provides a clipping force in the assembly direction and / or an unclipping force against the assembly direction. In other words, a structural feature is provided on one of the clamping elements that holds the bolt or bolt element arranged in the clamping opening in a sufficiently rigid clip such that, in particular, the release force is similar to the pull-out force of a screw connection. This offers the advantage that a stiffening element can be designed to provide a particularly advantageous and, in particular, a particularly high unclipping force, especially with regard to the unclipping force or the force against the assembly direction.

[0022] In a further advantageous embodiment of the invention, the clamping elements, in particular those provided by the stiffening or several stiffenings, 24-3272 PIF

[0023] 5

[0024] The specified release force is greater than or equal to 600 N, and in particular greater than or equal to 800 N. In other words, the clip or locking element, with its corresponding structural features, is designed such that a release force of 600 N or greater is required to disengage the bolt or bolt element from the locking element in the opposite direction to the assembly direction. This offers the advantage of maintaining the assembly position and / or ensuring compliance with crash design requirements.

[0025] In a further advantageous embodiment of the invention, the cover is formed by or with the base body and / or is resiliently designed. In other words, the cover is formed integrally with the base body and thus, in particular, as a single piece. Additionally or alternatively, the cover is resilient, meaning it is at least somewhat movable relative to the base body. In other words, a resilient and / or fixed cover is thus provided. This offers the advantage that the cover can create an attractive appearance, for example, in the vehicle interior, and, due to its resilient or fixed design, can be held in position and thus moved accordingly for removal or disassembly of the trim.

[0026] In a further advantageous embodiment of the invention, the cover plate is connected to the base body by means of a clip connection and / or via a rail, which in particular has an undercut. In other words, the cover plate itself is held to the base body by a clip. Additionally or alternatively, a rail system is provided, which accordingly has, for example, an undercut on one side, wherein, for example, the rails of the cover plate and the base body interlock to create the connection between the cover plate and the base body and can also be clipped together. This offers the advantage that a customized cover plate can be designed, which, for example, can be adapted to the requirements, in particular in terms of shape and / or appearance or material for a surface in a vehicle interior, and the locking element can remain the same for different trim elements.Furthermore, the aperture can be mounted, for example, floating and clipped relative to the base body, which allows for particularly advantageous handling during disassembly and / or the reuse of the locking element. 24-3272 PIF.

[0027] 6

[0028] In a further advantageous embodiment, the connection between the base body and the cover plate is floating and / or the release direction of the cover plate is perpendicular to both the assembly and disassembly directions. Additionally or alternatively, at least one locking hook is provided on the cover plate, which serves to fix the cover plate, for example, to the cladding element and / or the structural element. In other words, the cover plate is movable relative to the base body. To prevent the cover plate from being accidentally detached during assembly or disassembly, both the assembly and disassembly directions are substantially perpendicular to the release direction of the cover plate from the base body.Additionally or alternatively, at least one locking hook is formed on the cover, by which the cover can be advantageously attached to the trim element and / or, for example, the structural element in the mounting position or in the mounted state, in order to enable, for example, a particularly advantageous appearance of the vehicle interior.

[0029] In a further advantageous embodiment of the invention, the trim element is a door trim element or a door trim panel, and / or the vehicle structure is a vehicle door. In other words, the trim is a door trim panel, wherein the trim element provides an interior trim element for the vehicle door, such that the vehicle structure, on which the trim support is formed at least in the form of the bolt element, represents the vehicle door. This offers the advantage that a vehicle door can be designed particularly advantageously.

[0030] A second aspect of the invention relates to a method for dismantling a cover according to the first aspect of the invention, in which a certain or minimum specified force is transmitted through the cover along the dismantling direction and thus perpendicular or substantially perpendicular to the assembly direction, whereby the bolt element is guided out of the assembly position and thus out of the clamping opening via the exit opening.

[0031] Advantages, advantageous developments, and embodiments of the first aspect of the invention are to be considered advantages, advantageous developments, and embodiments of the second aspect of the invention, and vice versa. Reference is made here again explicitly to the definition of "essentially perpendicular," which was used to describe the first aspect of the invention. 24-3272 PIF

[0032] 7

[0033] A third aspect of the invention relates to a fastening device for a cover comprising a locking element and a corresponding bolt element, wherein the locking element has a base body and a clamping opening extending through it and provided with clamping elements, which is designed to receive the bolt element along a mounting direction and in which the bolt element can be clipped in a mounting position by inserting the bolt element, in particular completely, into the clamping opening and fixing it there by the clamping elements.

[0034] The fastening device according to the invention is provided in such a way that the clamping elements are arranged on the clamping opening such that a discharge opening is formed, and a cover plate is arranged on the base body on the side of the clamping opening opposite the discharge opening, wherein the orientation of the discharge opening and the cover plate defines a disassembly direction which is essentially normal to the assembly direction, and the cover plate is designed to remove the bolt element from the clamping opening via the discharge opening when a predetermined force is applied to it along the disassembly direction.

[0035] In other words, the aperture is designed to utilize a predetermined force acting upon it along the disassembly direction, so that the bolt element passes through the exit opening along the disassembly direction and is thus ejected from the clamping opening. The fastening device presented here is, in particular, a fastening device used in the first aspect of the invention, which is therefore used in the method according to the second aspect of the invention.

[0036] Advantages, beneficial developments and embodiments of the first and second aspects of the invention are to be regarded as advantages, beneficial developments and embodiments of the third aspect of the invention and vice versa.

[0037] Further features of the invention will become apparent from the claims, the figures, and the description of the figures. The features and combinations of features mentioned above in the description, as well as the features and combinations of features mentioned below in the description of the figures and / or shown in the figures alone, are not only usable in the combinations specified, but also in other combinations or on their own.

[0038] The invention will now be explained in more detail with reference to a preferred embodiment and the drawings. (See: 24-3272 PIF)

[0040] Fig. 1 shows a schematic perspective view of a fastening device for a fairing for a motor vehicle in a first embodiment with a floatingly mounted panel; and

[0041] Fig. 2 shows a schematic perspective view of the fastening device in a second embodiment with a spring-loaded, fixed cover on the base body of a locking element with a bolt element in mounting position.

[0042] Fig. 1 shows a schematic perspective view of a fairing 1 for a motor vehicle with a fastening device 2 in a first embodiment. The fastening device 2 comprises a locking element 3 and a corresponding bolt element 4, wherein the locking element 3 has a base body 5 and a clamping opening 7 extending through it and provided with clamping elements 6, which is designed to receive the bolt element 4 along a mounting direction 8 and in which the bolt element 4 can be clipped in a mounting position shown in Fig. 2 by inserting the bolt element 4, in particular completely, into the clamping opening 7 and fixing it there by the clamping elements 6.

[0043] The fairing 1 is used in particular for a motor vehicle and comprises a fairing element, represented here by the locking element 3, and a fairing support 13, represented by the bolt element 4, whereby the fairing element is held on the fairing support 13 by the fastening device 2. The fairing support 13 is held in its operating position, or in the operating position of the fairing 1, on a vehicle structure 12, such as a body and / or a frame.

[0044] To enable easy disassembly using a method described here with reference to the cover 1 and the fastening device 2 presented here, the clamping elements 6 are arranged on the clamping opening 7 such that a discharge opening 9 is formed and a cover 10 is arranged on the base body 5 on the side of the clamping opening 7 opposite the discharge opening 9, wherein a disassembly direction 11 is defined by the orientation of the discharge opening 9 and the cover 10, which is essentially perpendicular to the mounting direction 8 and the cover 10 is designed to allow for disassembly when applied to it.

[0045] 9

[0046] The acting, predetermined force along the disassembly direction 11 removes the bolt element 4 from the clamping opening 7 via the exit opening 9.

[0047] Herein, a method is presented in which the disassembly of the cover 1 is carried out in such a way that a certain force acts on the cover 10 along the disassembly direction 11 and is thus transmitted essentially perpendicular to the assembly direction 8, whereby the bolt element 4 is led out of the clamping opening 7 via the exit opening 9 and thereby releases the assembly position or the bolt element 4 leaves the assembly position and thus the clipping.

[0048] In other words, with regard to end-of-life vehicle regulations, which stipulate which raw materials must be recovered from end-of-life vehicles, it is advantageous if particularly quick disassembly, especially of the door panel or trim panel 1, can be carried out. This contrasts with the specific crash design of modern door panels, which, similar to a screw connection, require tensile loads in the assembly direction and thus also in the clip direction.

[0049] The cover 1, the fastening device 2, and a method for disassembling the cover 1 presented here enable a sufficiently strong clipping action, with a release force similar to that of a screw connection. Disassembly is facilitated by pulling the clip perpendicular to the clip direction from a fastening element, for example, the bolt or bolt element 4. The force is applied via a cover 10, which is either floating as shown in Fig. 1 and / or spring-mounted as shown in Fig. 2, allowing for visually clean integration into surrounding components.Thus, a laterally open clip in the form of the base body 5 or the locking element 3 with corresponding or associated exit opening 9 is provided, which has corresponding structural measures, in particular in the form of stiffenings of the clamping elements 6, in order to enable a clipping force against the mounting direction 8 of more than 600 N or at least 600 N.

[0050] The cover 10, which is mounted and clipped to the base body 5 via a rail 14 as shown in Fig. 1, allows a tensile force to be applied which can release the bolt element 4 by pulling the clip, and thus the locking element 3, laterally away from the bolt or bolt element 4. The cover 10 can have locking hooks 15 to enable, for example, the attachment of the cover 10 to the cladding carrier 13. 24-3272 PIF

[0051] 10

[0052] It is provided that at least one of the clamping elements 6 may in particular have a stiffening in order to specify the clipping force or unclipping force accordingly in the assembly direction 8 or contrary to the assembly direction 8 in order to achieve, for example, the required 600 N.

[0053] As shown in Fig. 1, the aperture 10 is connected to the base body 5 by means of a clip connection over a rail 14. The release direction of the aperture 10 is essentially perpendicular to the assembly and disassembly directions.

[0054] Fig. 2 shows an alternative embodiment in which the aperture 10 is formed by the base body 5 and is resilient. In addition to the floating connection between the base body 5 and the aperture 10 shown in Fig. 1, a fixed connection can thus be achieved.

[0055] The spring-loaded mounting of the cover 10 relative to the base body 5 is achieved by corresponding spring elements 16. Both the spring-loaded mounting and the corresponding design with locking lugs or locking hooks 15 result in a particularly advantageous integration, for example, of the vehicle interior.

[0056] In addition to the method presented here for dismantling the fairing 1, the fairing 1 itself and the fastening device 2 presented here, a motor vehicle is to be presented which has a corresponding fairing 1 or whose fairing 1 can be dismantled by means of a corresponding method or whose fairing 1 is fastened by means of the fastening device 2.

[0057] Thus, a detachable clip for replacing screws for a corresponding crash trigger system for motor vehicles is presented.-3272 PIF
