[0015] Other objects, features and advantages of the invention will become apparent from the following description, given solely by way of non-limiting example and made with reference to the accompanying drawings in which:

[0016] - Figure 1 represents an example of a motor vehicle; and

[0017] - Figures [Fig. 2], [Fig. 3] and [Fig. 4] represent partial sections of an example of a door. Detailed description

[0018] We refer to [Fig.1] which represents a motor vehicle 1 in an orthogonal coordinate system X, Y, Z. The X axis is parallel to the longitudinal direction of the vehicle 1 and oriented towards the front of the vehicle 1 in normal operation, the Y axis is perpendicular to the X axis and oriented towards the left of the vehicle 1 viewed from the front, and the Z axis is perpendicular to the plane defined by the X and Y axes and oriented towards the roof of the vehicle 1.

[0019] Figures 2 and 3 represent a partial section of an example of door 2 of vehicle 1 along a plane AA shown in [Fig.1].

[0020] The door includes a window 3 and a trim 4.

[0021] More specifically, [Fig.2] illustrates an upper portion 5 of the trim 4 of the door 2 and [Fig.3] illustrates a lower portion 6 of the trim 4 of the door 2.

[0022] The trim 4 comprises a frame 7 forming a skeleton of the door 2, a textile 8 and a system for fixing said textile 8 to an outer face of the frame 7 opposite the window 3. The textile 8 covers the frame 7, providing an aesthetic and ergonomic effect to the door 2 and protecting the trim components 4.

[0023] In the embodiment illustrated in the figures, the frame 7 comprises a support 9 and a reinforcing plate 10 having a curved upper part 10a covering the support 9. The reinforcing plate 10 further comprises a concave part 10b connected to the upper part 10a, and a vertical flat part 10c connected to the concave part 10b and extending along the Z axis. The reinforcing plate 10 has an inner face 10d fixed to the support 9 by means of fastening means 11 and an outer face 10e opposite the inner face 10b onto which the textile 8 is attached by means of the fastening system. The reinforcement plate 10 facilitates the mounting of the textile 8 onto the frame 7 of the door 2. The means for fixing 11 of the reinforcement plate 10 onto the support 9 include threaded screws lia suitable for being inserted into holes 11b, 1 le located respectively on the support 9 and on the reinforcement plate 10 provided for this purpose..

[0024] In one embodiment not shown, the frame 7 does not include a reinforcing plate 10, and the textile 8 is attached directly to the support 9 via the fastening system. In another embodiment not shown, the frame 7 includes a first reinforcing plate 10 located in the upper portion 5 of the lining 4 and a second reinforcing plate 10 located in the lower portion 6 of the lining 4.

[0025] The textile 8 is substantially rectangular and comprises four sides, an inner face 8a in contact with the outer face 10e of the reinforcement plate 10 of the frame 7, and an outer face 8b facing 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 foam on its inner face 8a.

[0026] The textile 8 fixing system comprises four fixing members 12 for fixing the four sides of the textile 8 onto the reinforcement plate 10 so as to press the textile 8 against the outer face 10e of the reinforcement plate 10. A first and a second fixing members 12a, 12b extend along the X axis to fix two sides of the textile 8 extending along the X axis, more precisely the horizontal sides of the textile 8, onto the reinforcement plate 10.

[0027] The first fixing member 12a is illustrated in [Fig.2] and is disposed in the upper portion 5 of the trim 4 and the second fixing member 12b is illustrated in [Fig.3] and is disposed in the lower portion 6 of the trim 4.

[0028] The textile 8 fastening system further comprises a third fastening member 12c shown in [Fig. 4] and a fourth fastening member not shown extending along the Z-axis to fix two sides of the textile 8 extending along the Z-axis, more precisely the vertical sides of the textile 8, onto the reinforcement plate 10. Each The fixing element 12a, 12b, 12c is further fixed to one end of the reinforcement plate 10 of the frame 7.

[0029] The first fixing member 12a is fixed to the upper part 10a of the reinforcement plate 10 and the second fixing member 12b is fixed to the vertical flat part 10c of the reinforcement plate 10.

[0030] The fastening members 12a, 12b, 12c allow the textile 8 to be fixed to the outer face of the frame 7, by stretching the textile 8 so that it is pressed and / or stretched against the reinforcement plate 10 of the frame 7.

[0031] As illustrated in [Fig. 1], the first fastening member 12a comprises a fastening key 13 attached to the textile 8 by means of at least one staple or seam. The fastening key 13 comprises a stem adapted to be clipped by complementary shape into a recess 14 in the upper part 10a of the reinforcement plate 10 of the frame 7. The fastening key 13 is interposed between the reinforcement plate 10 and the support 9 and comprises an angular profile complementary to the shape of the recess 14 in the reinforcement plate 10. A hook 15 integral with the upper part 10a of the reinforcement plate 10 locks the fastening key 13 along the Z axis.

[0032] The trim 4 further includes an added piece 16 adapted to press the textile 8 against the concave portion of the frame 7. The added piece 16 includes, for example, a trim element from the motor vehicle 1, such as a door armrest. The added piece 16 is attached to the reinforcement plate 10 by means of a fastening mechanism. As the fastening elements 12a, 12b, 12c are located at the ends of the textile 8, the added piece 16 allows the textile 8 to be pressed against the concave portion 10b of the reinforcement plate 10, in which the textile 8 is no longer held taut by the fastening elements 12a, 12b, 12c. The fixing mechanism includes, for example, screws and holes in the reinforcement plate 10. The screws pass through holes in the add-on piece 16 and holes in the textile 8 and engage in the holes in the reinforcement plate 10 to hold the add-on piece 16 onto the textile 8 and the reinforcement plate 10.

[0033] Stitching or stapling can be applied to the textile 8 to give it a specific shape that aids in its attachment to the reinforcement 7. As illustrated in [Fig. 2], the second fastening element 12b of the textile 8 includes a staple 17 for attaching the textile 8 to the reinforcement plate 10. The free end of the vertical flat portion 10c of the reinforcement plate 10 includes a lip 18 for better retention of the stapled textile 8. The textile 8 is held taut between the support 9 and the reinforcement plate 10.

[0034] In an embodiment not shown, the second fastening member 12b comprises a fastening key attached to the textile 8 by means of at least one staple or seam and clipped into a recess in the vertical flat portion 10c of the reinforcement plate 10 by complementary shape. The rim 18 of the reinforcement plate 10 allows the key to be retained in the Z direction.

[0035] Fig. 3 represents a partial section of door 2 along a plane BB shown in Fig. 1.

[0036] The third fastening element 12c comprises a fastening key 19 interposed between the reinforcement plate 10 and the support 9. The fastening key 19 is attached to the textile 8 by means of at least one staple or seam and is clipped to the reinforcement plate 10 by complementary shape. The reinforcement plate 10 longitudinally locks the fastening key 19 in the direction X by means of a lip 20. The reinforcement plate 10 is fixed to the support 9 by means of fastening means 21. The fastening means 21 comprise threaded screws 21a adapted to be inserted into holes 21b, 21c located respectively on the support 9 and on the reinforcement plate 10 provided for this purpose.

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

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

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

[0040] The fastening key 13, 19 advantageously comprises a lightweight and readily producible material. The fastening key 13, 19 comprises, for example, plastic.

[0041] When the fastening members 12a, 12b, 12c are fixed to the textile 8 and to the reinforcement plate 10, the textile 8 is stretched between the upper portion 5 of the lining 4 and the lower portion 6 of the lining 4, that is to say between the curved upper part 10a of the reinforcement plate 10 and the vertical flat part 10c of the reinforcement plate 10, and between the two longitudinal ends of the reinforcement plate 10.

[0042] By way of non-limiting example, the reinforcing plate 10 of the frame 7 corresponds to a door panel. The support 9 of the frame 7 corresponds to the door frame.

[0043] A method for mounting the trim 4 onto the door 2 is now described.

[0044] During a first step, the fastening members 12a, 12b, 12c are fixed onto the textile 8.

[0045] The fixing of the fixing keys 13, 19 on the textile 8 is done by means of at least one stapling or a stitch.

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

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

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

[0049] During a third step, the reinforcing plate 10 comprising the textile 8 is fixed to the support 9 of the frame 7 by means of the fixing means IL. The third step of the process is necessary when the frame 7 comprises one or more reinforcing plates 10. In an embodiment not illustrated, the frame 7 does not include a reinforcing plate 10 and the textile 8 is directly fixed to the support 9 by means of the fixing system of the textile 8.

[0050] During a fourth stretching step of the textile 8, the added piece 16 is assembled onto the reinforcement plate 10 to press the textile 8 against the frame 7 in the concave portion 10b of the reinforcement plate 10 of the frame 7. Of course, this does not depart from the scope of the invention if the trim 4 has a different composition. It is thus possible to design a trim 4 comprising a reinforcement plate 10 that has several concave portions 10b. It is also possible to design a dashboard trim 4 for a motor vehicle.

[0051] In one embodiment of the invention, the stretching step of the textile 8 is carried out prior to the step of fixing the reinforcement plate 10 comprising the textile 8 onto the support 9 of the frame 7.

[0052] The trim 4 for the automotive vehicle 1 component ultimately reduces the weight of the vehicle 1 by eliminating the glue used in standard designs and thus reduces CO2 emissions. It also facilitates the mounting and dismounting of the textile 8 on the frame 7 and allows for customization of said textile 8 according to the user's preferences. Furthermore, the trim 4 as described extends the service life of the automotive vehicle 1 components.
