Domaine technique

[0001] The present invention relates to a vehicle trim assembly, comprising a dashboard having a rear transverse edge, the edge being intended to be arranged near the windshield of the vehicle when the trim assembly is mounted in it, and at least one assembly piece engaging with the dashboard for fixing the dashboard to the vehicle body, each assembly piece having a locking device for the assembly piece on the dashboard (102), the locking device being movable between a first locked position, in which the assembly piece is immobilized on the dashboard (102), and a second unlocked position, in which the assembly piece can be removed from the dashboard. Technique antérieure

[0002] Such a set of coverings is known from document FR 3 101 056 A1. With reference to the figure 1 From this document, this known trim set includes a dashboard 12 and an assembly piece 10. The assembly piece 10 is locked onto the dashboard 12 by means of a flexible hook 16B.

[0003] In a motor vehicle 50 equipped with such a trim assembly 10, 12, a mechanic may want to detach the dashboard 12 from the body 14 of the vehicle 50, for example, to carry out a repair. The trim assembly 10, 12 is provided with an access opening allowing the mechanic to perform this operation. This access opening consists of a hole 12B in the dashboard 12 located above the flexible hook 16B. In order to detach the dashboard 12 from the body 14, the mechanic inserts a long, thin tool through the hole 12B to press against the hook 16B. In this way, the trim assembly 10, and thus the body 14, are unlocked from the dashboard 12.

[0004] One drawback of this known unlocking solution is that it requires the dashboard manufacturer to reserve a specific area at the front of the dashboard 12 for the access hole 12B. Indeed, the access hole 12B cannot be placed just anywhere, as it must allow easy access to the hook 16B. However, this specific area is not always suitable for an access hole. Furthermore, this area can then only be used with difficulty for other functions. Document FR 3 101 056 A1 proposes integrating the access hole 12B into a demister grille. However, the demister grille must then necessarily be placed above the hook 16B, even if this position does not allow for effective demisting of the vehicle's windshield. Furthermore, in this known solution, the access hole 12B is located in a visible area of ​​the dashboard 12, which may impact the aesthetic appearance of said dashboard 12. Résumé

[0005] One aim of the present invention is therefore to provide a trim assembly in which the access opening for detaching the dashboard is located in a more suitable location on the dashboard.

[0006] According to the present invention, this goal is achieved with a trim assembly as defined in §

[0001] , which is characterized in that the trim assembly further comprises, for each assembly piece, an actuating lever for the locking device of the assembly piece, the actuating lever enabling the locking device to be moved from its first to its second position, and an access opening for the actuating lever associated with the assembly piece, the access opening being located on the edge of the dashboard.

[0007] Indeed, by incorporating an operating lever, the access opening can be relocated to the rear edge of the dashboard, a less obtrusive and less visible location. At the same time, the access opening remains easily accessible to a technician.

[0008] The rear section refers to the part of the dashboard opposite the area containing the user's interaction zones (steering wheel, instrument cluster, screen, etc.). The rear section corresponds to the area near the vehicle's windshield.

[0009] The actuating lever according to the present invention acts as a relay which allows the force exerted by the technician with his tool to be transmitted to the locking device of the assembly part.

[0010] The features described in the following paragraphs may optionally be implemented, independently of each other or in combination with each other: Each actuating lever is arranged on the dashboard; the dashboard comprises a main body and a cover mounted on the main body, each actuating lever being arranged on the main body; each actuating lever is made of the same material as the main body; each actuating lever is connected to the dashboard by a joint allowing the actuating lever to pivot relative to the dashboard; each actuating lever includes an actuating area for applying pressure to the locking device associated with the actuating lever in order to move the locking device to its unlocked position; each actuating area consists of a projection near the associated locking device; each actuating area consists of a flat surface near the associated locking device; each actuating lever is arranged on its associated mounting part;Each actuating lever is connected at one end to the locking device of its associated assembly part, so that it can act by pulling on the associated locking device; each actuating lever has a bearing area located at the access opening associated with the actuating lever, each actuating lever being operated by exerting pressure on its bearing area; each actuating lever includes a section for receiving a windshield seal; each actuating lever includes a protective edge near its receiving section to protect a windshield seal received in its receiving section; each locking device is a flexible hook.

[0011] The present invention also relates to a motor vehicle comprising a body and a bodywork assembly as defined above, the bodywork assembly being fixed to the body using its assembly parts.

[0012] Furthermore, the present invention relates to an assembly part for connecting a dashboard to a vehicle body, the assembly part comprising a locking device for the assembly part on a dashboard, the locking device being movable between a first locked position and a second unlocked position, characterized in that it comprises an actuating lever for the locking device, the actuating lever allowing the locking device to be moved from its first to its second position.

[0013] Preferably, the assembly part according to the present invention comprises one, several, or all of the following characteristics: The actuating lever is connected at one end to the locking device, so that it can act by pulling on the locking device; the locking device is a flexible hook; the passage of the locking device from the first to the second position is achieved by deforming at least a portion of the locking device; means for retaining the locking device in the second position; the means for retaining it in the second position include a retaining tab mounted on the assembly piece and a depression complementary to the retaining tab, the retaining tab cooperating with the depression to hold the actuating lever in an active position, a slot being made in the actuating lever and receiving the retaining tab at least in the second position.

[0015] With reference to figures 1 à 7 We will now describe a set of automotive vehicle trim according to a first embodiment of this disclosure.

[0016] This trim assembly 100 includes a dashboard 102 and one or more assembly parts 104. At the figure 1 Only one assembly part 104 is shown. However, preferably, several assembly parts 104 are provided along the dashboard 102. Hereafter, we will only be concerned with the assembly part 104 shown, but, of course, everything said in relation to this assembly part 104 applies in full to any other assembly parts not shown in the trim assembly 100.

[0017] The dashboard 102 has a rear transverse border 106. When the trim assembly 100 is fitted in a motor vehicle, the border 106 is arranged close to the windscreen of the motor vehicle.

[0018] The dashboard 102 comprises a main body 108 and a cover 110, mounted on the main body 108.

[0019] In an embodiment not shown, the headgear 110 and the main body 108 are made as a single piece, for example by injection of plastic material.

[0020] Assembly part 104 engages with dashboard 102. Assembly part 104 allows dashboard 102 to be attached to the body of a motor vehicle. As more clearly seen in the figure 2 The assembly part 104 is received in a reception area 112 of the main body 108 of the dashboard 102. The reception area 112 is shown separately in the figure 4 , and assembly part 104 is shown separately to figures 5 And 6 .

[0021] The assembly part 104 comprises a male part 114 and a female part 116. The assembly part 104 is clipped into the receiving area 112 of the main body 108 of the dashboard 102 by means of its male part 114. The male part 114 is then received into the receiving area 112. For this purpose, the male part 114 has a locking device 118. Here, this locking device is in the form of a flexible hook 118.

[0022] The female part 116 of the assembly part 104 is preferably U-shaped. It comprises a base 116A and two arms 116B perpendicular to the base 116A. The female part 116 allows the bodywork assembly 100 to be attached to the body 120 of a motor vehicle, see the figure 7 .

[0023] According to this disclosure, an actuating lever 122 is arranged on the assembly part 104. The actuating lever 122 is connected by one 124 of its ends to the locking device, i.e. to the flexible hook 118. Thus, the actuating lever 122 can act in tension on the flexible hook 118.

[0024] The other free end 126 of the actuating lever 122 has a bearing area 128. The actuating lever 122 is operated by exerting pressure on its bearing area 128.

[0025] A slot 130 is made in the actuating lever 122. This slot 130 accommodates a retaining tab 132. The retaining tab 132 is mounted on the female part 116 of the assembly part 104. More precisely, the retaining tab 132 is located on one of the arms 116B of the female part 116.

[0026] A depression 134 complementary to the retaining tab 132 is made on the actuating lever 122 near the light 130. The retaining tab 132 can cooperate with the depression 134 to hold the actuating lever 122 in an active position, i.e. an unlocking position of the assembly part 104 of the dashboard 102.

[0027] With reference to figures 1 , 2 And 7 The actuating lever 122 is located under the cover 110 of the dashboard 102. More precisely, the free end 126 of the actuating lever 122 is located below the edge 106 of the cover 110. The free end 126 and therefore the bearing area 128 of the actuating lever 122 are accessible from the outside through an access opening 136. The access opening 136 is located on the edge 106 of the dashboard 102.

[0028] With reference to the figure 7 We will now describe the unlocking process of the assembly part 104 which allows a mechanic to detach the dashboard 102 from the body 120 of the motor vehicle.

[0029] To detach the dashboard 102 from the body 120, the mechanic passes a long, thin tool 138 through the access opening 136 to press against the support area 128 of the actuating lever 122. In this way, the actuating lever 122 is forced downwards to reach an active position shown in dotted lines in the figure 7 During this movement of the actuating lever 122, the retaining tab 132 engages in the recess 134. This holds the actuating lever 122 in its active position. The mechanic can then remove the tool 138.

[0030] Since the flexible hook 118 is attached to the lower end 124 of the actuating lever 122, it follows the movement of the latter. Therefore, the hook 118 is lifted (see the dotted line in the figure 7 ) and cleared from reception area 112 of the main body 108.

[0031] By pressing the actuating lever 122, the flexible hook 118 can therefore be moved from a first locked position P1, shown in solid lines in the figure 7 , in which the assembly part 104 is immobilized on the dashboard 102, towards a second unlocked position P2, shown in dotted lines in the figure 7 , in which the assembly part 104 can be removed from the dashboard 102.

[0032] In other words, the actuating lever 122 allows the flexible hook 118 to be moved from its locked position P1 to its unlocked position P2.

[0033] Once the flexible hook 118 of the assembly part 104 is stopped in its unlocked position P2, the mechanic can then remove the dashboard 102 from the body 120. This has the effect of separating the assembly part 104 from the dashboard 102. The assembly part 104 is then no longer engaged with the dashboard 102, while remaining engaged with the body 120.

[0034] With reference to figures 8 à 11 We will now describe a 200-piece clothing assembly according to a second embodiment of this disclosure. We will focus solely on the differences compared to the first embodiment. For similar elements, reference is made to the above description of the first embodiment.

[0035] The second embodiment 200 differs from the first embodiment 100, notably in that the actuating lever 222 is not arranged on the assembly part 204, but rather on the dashboard 202. More precisely, and with reference to the figure 9 The actuation lever 222 is arranged on the main body 208 of the dashboard 202. Preferably, the actuation lever 222 is made of the same material as the main body 208. Alternatively, the actuation lever 222 is made of the same material as the cover 210.

[0036] The actuating lever 222 is connected to the main body 208 by a joint 223. This joint 223 allows the actuating lever 222 to pivot relative to the main body 208.

[0037] Alternatively, the actuating lever 222 is connected to the main body 208 by a film hinge and / or a more flexible area. This connection allows the actuating lever 222 to pivot relative to the main body 208 by elastic deformation of the actuating lever 222.

[0038] Near the joint 223, the actuating lever 222 includes an actuating area 225. The actuating area 225 allows pressure to be exerted on the flexible hook 218 of the assembly part 204. This allows the flexible hook 218 to be moved to its unlocked position P2.

[0039] In this second embodiment, the actuation zone consists of a flat 225 which is located near and above the flexible hook 218 of the assembly part 204.

[0040] There figure 11 illustrates the unlocking process of assembly part 204 of the second embodiment 200.

[0041] To detach the dashboard 202 from the body 220, simply pass a long, thin tool through the access opening 236 to press on the actuating lever 222. This pivots the actuating lever 222 downwards and brings it to its active position, shown by the dotted line in the diagram. figure 11 During this pivoting movement, the flat 225 of the actuating lever 222 presses against the flexible hook 218 of the assembly part 204. The flexible hook 218 is then forced downwards and reaches its unlocked position P2, indicated by the dotted line. The dashboard 202 can then be removed from the body 220.

[0042] With reference to figures 6, 7 And 10, 11It should be noted that, in the second embodiment, the orientation of the flexible hook 218 of the assembly part 204 is reversed compared to the orientation of the flexible hook 118 of the assembly part 104 in the first embodiment. In the second embodiment, the hook 218 faces the actuating lever 222, whereas, in the first embodiment, the flexible hook 118 faces away from the actuating lever 122.

[0043] With reference to the figure 12 , we will now describe a 300 clothing assembly according to a third embodiment of this disclosure.

[0044] This third embodiment is a variant of the second embodiment, and we will focus here only on the differences compared to the second embodiment. For comparable elements, reference is made to the above description of the second embodiment.

[0045] In this third embodiment, the actuation zone of the actuating lever 322 consists of a projection 325 located near and above the flexible hook 318 of the assembly part 304.

[0046] Furthermore, in this embodiment, the actuating lever 322 includes a receiving section 340. This receiving section 340 is preferably located at the free end of the actuating lever 322. The receiving section 340 serves to support a portion of the windshield seal 10. In the assembled state of the trim assembly 300, the receiving section 340 is positioned so that the windshield seal 10 attached to it is located between the windshield 12 of the motor vehicle and the dashboard 302. This ensures a seal between the windshield 12 and the dashboard 302.

[0047] The actuating lever 322 may include a protective edge 342 on the edge of its receiving section 340. This protective edge 342 protects the windshield seal 10 from the tip of a tool 138 inserted into the access opening 336.

[0048] In conclusion, it should be noted that the trim assembly described in this disclosure is characterized by a set of access openings and associated operating levers, which together constitute a particularly advantageous dashboard detachment interface. Indeed, this interface is virtually invisible to vehicle passengers, as the access openings are located at the rear of the dashboard near the windshield. The interface is therefore relocated to a peripheral and invisible area of ​​the dashboard, thus removing a constraint in the design of the visible areas of the dashboard.

[0049] In an embodiment not shown, the dashboard 102 is produced by injection.
