[0015] Further aims, features and advantages of the invention will become apparent from the following description, which is given merely as a non-limiting example and with reference to the accompanying drawings, in which: Fig. 1 represents an example of a motor vehicle; and Fig. 2, Fig. 3 and Fig. Four partial sections of an example of a door are shown. Detailed description

[0016] Referring to Fig. Figure 1 shows a motor vehicle 1 in an orthogonal coordinate system X, Y, Z. The X-axis runs parallel to the longitudinal direction of the vehicle 1 and is oriented forward in the direction of travel, the Y-axis runs perpendicular to the X-axis and is oriented to the left with respect to the frontal view of the vehicle 1, and the Z-axis runs perpendicular to the plane spanned by the X- and Y-axes and is oriented towards the roof of the vehicle 1.

[0017] The Fig. 2 and Fig. Figure 3 shows a partial section of an example of a door 2 of vehicle 1 according to a section plane AA, which is in Fig. 1 is shown.

[0018] The door includes a pane 3 and a trim panel 4.

[0019] More precisely, it illustrates Fig. 2 an upper section 5 of the trim 4 of the door 2 and Fig. Figure 3 illustrates a lower section 6 of the trim 4 of door 2.

[0020] The cladding 4 comprises a frame 7, which forms the skeleton of the door 2, a textile 8, and a fastening system for the textile 8 on an outer surface of the frame 7, opposite the panel 3. The textile 8 covers the frame 7 to provide an aesthetic and ergonomic effect for the door 2 and protects components of the cladding 4.

[0021] In the embodiment illustrated by the figures, the framework 7 comprises a support 9 and a reinforcing plate 10 with an upper, curved section 10a that covers the support 9.

[0022] The reinforcement plate 10 further comprises a concave section 10b, which is connected to the upper section 10a, and a flat, vertical section 10c, which is connected to the concave section 10b and extends along the Z-axis. The reinforcement plate 10 has an inner surface 10d, which is attached to the support 9 by means of fasteners 11, and an outer surface 10e, which faces the inner surface 10d and on which the textile 8 is applied via the fastening system. The reinforcement plate 10 facilitates the mounting of the textile 8 on the frame 7 of the door 2. The fasteners 11 of the reinforcement plate 10 on the support 9 comprise threaded screws 11a, which are suitable for insertion into holes 11b, 11c, which are provided for this purpose on the support 9 and on the reinforcement plate 10, respectively.

[0023] In one embodiment (not shown), the frame 7 does not have a reinforcing plate 10, and the textile 8 is applied directly to the carrier 9 via the fastening system. In another embodiment (not shown), the frame 7 comprises a first reinforcing plate 10 arranged in the upper section 5 of the cladding 4, and a second reinforcing plate 10 arranged in the lower section 6 of the cladding 4.

[0024] The textile 8 is essentially rectangular and comprises four sides: an inner side 8a, which is in contact with the outer side 10e of the reinforcement plate 10 of the frame 7, and an outer side 8b, which faces the interior of the vehicle. In one embodiment, the textile 8 is woven from 100% recycled fibers. Advantageously, the textile 8 comprises polyester and / or a foam layer on its inner side 8a.

[0025] The fastening system of the textile 8 comprises four fastening elements 12 for attaching the four sides of the textile 8 to the reinforcement plate 10, thus allowing the textile 8 to lie against the outer surface 10e of the reinforcement plate 10. A first and a second fastening element 12a, 12b extend along the X-axis to fasten two sides of the textile 8, which extend along the X-axis, more precisely the horizontal sides of the textile 8, to the reinforcement plate 10.

[0026] The first fastening element 12a is in Fig. 2 shown and arranged in the upper section 5 of the cladding 4, and the second fastening element 12b is in Fig. 3 shown and arranged in the lower section 6 of the cladding 4.

[0027] The fastening system of the textile 8 further comprises a third fastening element 12c, shown in Fig. 4, and a fourth fastening element (not shown) extending along the Z-axis to fasten two sides of the textile 8, extending along the Z-axis, more precisely the vertical sides of the textile 8, to the reinforcement plate 10. Each fastening element 12a, 12b, 12c is further attached to one end of the reinforcement plate 10 of the frame 7.

[0028] The first fastening element 12a is attached to the upper section 10a of the reinforcement plate 10 and the second fastening element 12b is attached to the flat vertical section 10c of the reinforcement plate 10.

[0029] The fastening elements 12a, 12b, 12c serve to fasten the textile 8 to the outside of the frame 7 by tensioning the textile 8 so that it rests against and / or is taut against the reinforcement plate 10 of the frame 7.

[0030] As in Fig. As shown in Figure 1, the first fastening element 12a comprises a fixing key 13, which is attached to the textile 8 by at least one stapling or seam. The fixing key 13 includes a rod that can be clipped into a receptacle 14 of the upper section 10a of the reinforcement plate 10 of the frame 7 by positive locking. The fixing key 13 is arranged between the reinforcement plate 10 and the support 9 and has an angled profile that is complementary to the shape of the receptacle 14 of the reinforcement plate 10. A hook 15, which is connected to the upper section 10a of the reinforcement plate 10, locks the fixing key 13 in the direction of the Z-axis.

[0031] The cladding 4 further comprises an additional part 16, which is suitable for pressing the textile 8 against the concave area of ​​the frame 7. The additional part 16 has, for example, a decorative strip from the motor vehicle 1, such as a door armrest. The additional part 16 is attached to the reinforcement plate 10 via a fastening mechanism.

[0032] Since the fastening elements 12a, 12b, 12c are arranged at the ends of the textile 8, the additional part 16 allows the textile 8 to be pressed against the concave section 10b of the reinforcement plate 10, in which the textile 8 is no longer tensioned by the fastening elements 12a, 12b, 12c. The fastening mechanism includes, for example, screws and holes in the reinforcement plate 10. The screws pass through holes in the additional part 16 and holes in the textile 8 and engage in the holes of the reinforcement plate 10 to hold the additional part 16 on the textile 8 and the reinforcement plate 10.

[0033] Seams or tacks can be applied to the textile 8 to give it a specific shape that supports the attachment of the textile 8 to the frame 7. As in Fig. As shown in Figure 2, the second fastening element 12b of the textile 8 includes a stapling 17, which enables the textile 8 to be attached to the reinforcement plate 10. The free end of the flat vertical section 10c of the reinforcement plate 10 includes an edge 18, which allows for better retention of the stapled textile 8. The textile 8 remains taut between the support 9 and the reinforcement plate 10.

[0034] In an embodiment not shown, the second fastening element 12b has a fixing key which is attached to the textile 8 by at least one stapling or seam and is clipped into a receptacle of the flat vertical section 10c of the reinforcement plate 10 by positive locking. The edge 18 of the reinforcement plate 10 serves to hold the key in the Z-direction.

[0035] Fig. Figure 3 shows a partial section of door 2 according to a section plane BB, which is in Fig. 1 is shown.

[0036] The third fastening element 12c comprises a fixing key 19, which is arranged between the reinforcement plate 10 and the carrier 9. The fixing key 19 is attached to the textile 8 by at least one stapling or seam and is clipped onto the reinforcement plate 10 by a positive locking mechanism. The reinforcement plate 10 blocks the fixing key 19 in the longitudinal direction (X-direction) by means of an edge 20. The reinforcement plate 10 is fastened to the carrier 9 by means of fasteners 21. The fasteners 21 comprise threaded screws 21a, which are suitable for insertion into holes 21b, 21c, which are provided for this purpose on the carrier 9 and on the reinforcement plate 10, respectively.

[0037] The fixing keys 13, 19 can thus be similar to a fastening frame positioned on the circumference of the textile 8.

[0038] The fixing keys 13, 19 can have different shapes and, for example, be essentially square. In other embodiments not shown, the textile 8 has several fastening elements 12a, 12b, 12c on each of its sides and several fixing keys 13, 19 arranged on each of its sides, the keys 13, 19 thus having more compact shapes than a rod.

[0039] The size and shape of the key 13, 19 are adapted to the shapes and sizes of the textile 8 and the reinforcement plate 10.

[0040] The fixing key 13, 19 advantageously comprises a lightweight and easily manufactured material. The fixing key 13, 19 comprises, for example, plastic.

[0041] When the fastening elements 12a, 12b, 12c are attached to the textile 8 and to the reinforcement plate 10, the textile 8 is stretched between the upper section 5 of the cover 4 and the lower section 6 of the cover 4, i.e. between the upper curved section 10a of the reinforcement plate 10 and the flat vertical section 10c of the reinforcement plate 10, and between the two longitudinal ends of the reinforcement plate 10.

[0042] As a non-restrictive example, the reinforcement plate 10 of the scaffold 7 corresponds to a door panel. The support 9 of the scaffold 7 corresponds to the door frame.

[0043] Now, a procedure for mounting the trim panel 4 on the door 2 will be explained.

[0044] During a first step, the fastening elements 12a, 12b, 12c are attached to the textile 8.

[0045] The fixing keys 13, 19 are attached to the textile 8 by means of at least one stapling or a seam.

[0046] In a second step, the fastening elements 12a, 12b, 12c are attached to the reinforcement plate 10 of the frame 7. The textile 8 is attached to the reinforcement plate 10.

[0047] The fixing keys 13, 19 are attached to the frame 7 by clipping them on.

[0048] The second fastening element 12b of the textile 8 is, as in Fig. 3 shown, attached to the reinforcement plate 10 by stapling 17.

[0049] During a third step, the reinforcement plate 10 with the textile 8 is attached to the support 9 of the frame 7 via the fastening means 11. The third step of the method is required if the frame 7 comprises one or more reinforcement plates 10. In an embodiment not shown, the frame 7 does not have a reinforcement plate 10, and the textile 8 is attached directly to the support 9 via the textile 8's fastening system.

[0050] During a fourth step of stretching the textile 8, the additional part 16 is assembled on the reinforcement plate 10 to press the textile 8 against the frame 7 in the concave section 10b of the reinforcement plate 10. Naturally, the invention remains within the scope of the invention if the cover 4 has a different composition. For example, it is possible to design a cover 4 that includes a reinforcement plate 10 having several concave sections 10b. It is also possible to design a dashboard cover 4 for a motor vehicle.

[0051] In one embodiment of the invention, the step of stretching the textile 8 is carried out before the step of attaching the reinforcement plate 10 with the textile 8 to the support 9 of the frame 7.

[0052] The covering 4 of a component for a motor vehicle 1 ultimately enables a weight reduction of the vehicle 1 by eliminating the adhesive used in standard designs and a reduction in CO2 emissions. It also offers easy assembly and disassembly of the textile 8 on the frame 7 and allows for customization of the textile 8 according to the user's wishes. Furthermore, the covering 4 described above extends the service life of the components of the motor vehicle 1.
