Description

Technical Field

[0001] The present application claims priority from French application No. 1907779, filed on July 11, 2019, the content of which (text, drawings and claims) is incorporated herein by reference.

[0002] The technical background of the invention is that of door trim for motor vehicles. More specifically, the invention relates to sliding rails for door frames of motor vehicles and to side edge trims for such door frames. Background Art

[0003] Door frame rails are known in the prior art for engaging above a vehicle window along the upper portion of a vehicle door frame. When assembling these door frame rails, the front and rear door frame rails on the same side are adjacent and must be aligned relative to each other. These door frame rails must also be aligned relative to each trim piece on the corresponding side edge of the door frame. However, when the window is moved upward, the window may come to rest against the bottom of the door frame rail, potentially causing the door frame rail and its associated side edge trim piece to fold over, negatively impacting the aesthetics of the vehicle.

[0004] Document FR3049510A1 discloses a door frame rail for a motor vehicle. The rail includes a connecting element for engaging a trim component via a fixing aperture accommodated in the connecting element. The connecting element secures the door frame rail to the trim component to absorb the thrust exerted by the window on the bottom of the rail when the window is moved upward. This connecting element thus overcomes the problem of the door frame rail and the trim component flipping over when the window is raised.

[0005] Assembly of the trim component to the door frame requires securing the trim component to the door frame rail with the aid of the connecting element. This securing is achieved by applying a force from the trim component to the connecting element, securing the door frame trim component to the securing aperture of the connecting element. This force can also cause the connecting element to tilt toward the bottom of the door frame rail, thereby compromising the effectiveness of the door frame rail and altering its associated door frame rail positioning. Alignment between the trim component and the door frame is no longer guaranteed. Summary of the Invention

[0006] The present invention aims to provide a new fastening device for a side edge trim of a door frame of a motor vehicle in order to at least largely overcome the above-mentioned problems and also to bring about other advantages.

[0007] A further object of the present invention is to provide a fastening device for an edge trim of a vehicle door frame which is simple and economical both from the perspective of its execution and from the perspective of its production.

[0008] Another object of the present invention is to provide a universal and multifunctional fixing device for fixing an edge trim of a vehicle door frame, wherein the fixing device can be adapted to any type of vehicle door frame.

[0009] According to a first aspect of the present invention, at least one of the above-mentioned objectives is achieved by a fixing device for fixing a side edge trim of a door frame of a motor vehicle, the fixing device comprising: (i) a connecting part, the connecting part being used to cooperate with the side edge trim, the connecting part comprising: a fixing opening for fixing the side edge trim on the side where a fitting surface with the side edge trim is located, and a fixing part, the fixing part being used to allow the fixing device to be fixed on the door frame slide rail, and (ii) an anti-rotation component, the anti-rotation component being integrally connected to the connecting part and being located at a rear surface position opposite to the fitting surface, the anti-rotation component extending protruding relative to the rear surface of the connecting part.

[0010] Due to the anti-rotation member, the fixing device according to the first aspect of the present invention can prevent the connection part from rotating when the side edge trim is assembled on the fixing device.

[0011] The contact face of the connecting part is intended to be oriented towards the exterior of the motor vehicle, ie on the side of the side trim, and the rear face of the connecting part is intended to be oriented oppositely towards the interior of the motor vehicle and towards the door frame.

[0012] The connecting element's mating surface is configured to mate with the side edge trim via the connecting element's securing opening, and to mate with the door frame rail via the connecting element's securing member. The connecting element's securing opening enables the connecting element and the side edge trim to be integrally secured, for example, by mating with complementary shapes. The side edge trim presses against the mating surface when secured to the connecting element's securing opening.

[0013] The rear surface of the connecting part is integrally connected to the anti-rotation member.

[0014] The anti-rotation member is configured to engage with the door frame when the side edge trim is secured to the securing opening of the connecting component. When the side edge trim is assembled on the door frame slide rail using the connecting component, the anti-rotation member, by engaging with the door frame, can resist the force applied by the side edge trim to the mating surface.

[0015] The anti-rotation member thus forms a stop relative to the door frame rail, which restricts the rearward tilting of the connecting part when the side edge trim is assembled on the connecting part. In other words, the anti-rotation member restricts the connecting part from tilting toward the rear face of the door frame rail (that is, on the side of the passenger compartment of the motor vehicle).

[0016] Furthermore, the fixing device according to the first aspect of the invention enables the door frame slide rail to form a reference against the side edge of the door frame while forming a secure connection with the side edge trim, thanks to the connecting part, which is configured to absorb the thrust on the bottom of the slide rail caused by the window when it moves upwards.

[0017] The fixing member for allowing the fixing device according to the first aspect of the present invention to be fixed to the door frame slide rail is a removable fixing member. The fixing device according to the first aspect of the present invention and the door frame slide rail can be removed from each other and / or connected to each other. An example of a non-limiting example of a removable fixing member is a screw connection.

[0018] The fixing device according to the first aspect of the present invention advantageously includes at least one of the following improvements, and the technical features forming these improvements can be adopted individually or in combination:

[0019] the anti-rotation member is added to the connecting element. By added element is understood that the anti-rotation member and the connecting element are two distinct elements that are assembled together during the manufacture of the fixing device according to the first aspect of the invention. Alternatively, the anti-rotation member and the connecting element are optionally integrally formed, that is, they form a single, identical, monolithic component that cannot be disassembled without affecting the integrity of one or both of its constituent elements.

[0020] - In a first embodiment, the anti-rotation member is overmolded onto the connecting part. In this configuration, the anti-rotation member is added to the connecting part during the overmolding operation. In a second alternative embodiment to the first embodiment, the anti-rotation member comprises a first fixing element that cooperates with a second fixing element located on the connecting part. In this configuration, the anti-rotation member is added to the connecting part and the first fixing element is fixed to the second fixing element. For example, the first fixing element and the second fixing element are detachable fixing elements. For example, the engagement of complementary shapes between the male part of the first fixing element and the female part of the second fixing element (or vice versa) results in a detachable fixation. In particular, the first fixing element and the second fixing element are fitted together by snapping. In a third alternative embodiment to the first and second embodiments, the anti-rotation member is fixed to the connecting part by gluing;

[0021] the connecting element comprises at least one rib on its rear face, said rib extending protrudingly relative to said rear face. This rib contributes to the rigidification of the connecting element, so as to prevent it from bending when the side trim is fastened to the fastening device according to the invention;

[0022] The at least one rib extends longitudinally between the upper surface of the connecting part and the fixing opening. The upper surface of the connecting part couples the contact surface of the connecting part with the rear surface of the connecting part. When the fixing device according to the first aspect of the present invention is implemented, the upper surface of the connecting part is located on the side of the door frame slide rail. This arrangement of the ribs effectively limits the torque generated by the applied force when the door frame trim is assembled to the fixing device according to the first aspect of the present invention.

[0023] Advantageously, the connecting element comprises two ribs arranged parallel to each other and at a distance from each other. The presence of two ribs thus arranged improves the rigidity of the connecting element;

[0024] The ribs are laterally centered relative to the connecting element. This distribution of the ribs ensures greater rigidity and performance of the connecting element when it is assembled on the door frame rail and / or when it is fastened to the side edge trim.

[0025] The rib is preferably formed integrally with the connecting element. By "integrally formed" is understood that the rib and the connecting element form a single unit and are inseparable from one another, without affecting the integrity of one and / or the other of the rib and / or the connecting element. For example, the rib is obtained during the molding of the connecting element;

[0026] The anti-rotation member is located midway between the fixing opening and the upper surface of the connecting element. In other words, the anti-rotation member does not protrude beyond the upper surface of the connecting element. This advantageous configuration prevents the fixing device according to the first aspect of the present invention from tilting when the side trim is fixed.

[0027] - When the anti-rotation member is assembled on the connecting part, the at least one rib is received in the anti-rotation member. In other words, the receiving rib formed on the connecting part participates in the assembly and maintenance of the connecting part and the anti-rotation member;

[0028] - the connecting element has a trapezoidal general shape and / or the fixing opening has a trapezoidal shape;

[0029] - the fixing opening passes between the contact surface and the rear surface of the connecting part;

[0030] The connecting part is formed from a rigid plastic material, and the anti-rotation member is formed from an elastomer. Typically, the anti-rotation member is formed from a material having greater elasticity than the material forming the connecting part. The elasticity of the anti-rotation member enables it to be compressed between the connecting part and the door frame rail when the side edge trim is secured. The rigidity of the connecting part itself facilitates the securing of the side edge trim within the securing opening of the connecting part.

[0031] According to a second aspect of the present invention, there is provided a door frame slide rail for a motor vehicle, the door frame slide rail comprising a longitudinal body and a fixing device according to the first aspect of the present invention, the longitudinal body being configured for assembly along the door frame, the fixing device being integrally fixed to the longitudinal body of the door frame slide rail.

[0032] The integral attachment of the fixing device according to the first aspect of the present invention to the longitudinal body of the door frame rail is, for example, removable. The fixing device according to the first aspect of the present invention and the door frame rail can be detached from each other and / or connected to each other. An example of a removable attachment is, without limitation, screwing.

[0033] The longitudinal body of the door frame slide rail is configured to define a fixed frame along the door frame to which the longitudinal body is fixed, so as to guide the movement of the window assembled on the door frame.

[0034] The door frame slide rail according to the second aspect of the present invention advantageously includes at least one of the following improvements, and the technical features forming these improvements can be adopted individually or in combination:

[0035] The anti-rotation member of the fixture extends toward the door frame, such that a non-zero functional gap exists between the anti-rotation member and the door frame. This functional gap is estimated without the side trim assembled on the fixture. This functional gap is less than 0.5 mm; typically, it is approximately 0.2 microns.

[0036] According to a third aspect of the present invention, there is provided a motor vehicle comprising: (i) at least one side door housed in a door frame, (ii) a door frame slide rail according to the second aspect of the present invention, the door frame slide rail being positioned along an upper edge of the door frame, and (iii) a trim component positioned along a side edge of the door frame and fixed integrally with the door frame slide rail by means of its own fixing device.

[0037] The fixing device according to the first aspect of the present invention extends between the side edge trim and the door frame. In the motor vehicle according to the third aspect of the present invention, the anti-rotation member of the fixing device is capable of preventing the fixing device from turning over when the side edge trim is fixed to the connecting part. In other words, in the presence of the anti-rotation member, the turning over of the fixing device from the side edge trim to the door frame when the side edge trim is assembled is reduced or even prevented compared to a fixing device that is not provided with the anti-rotation member. In other words, the turning over of the fixing device from the fitting surface of the connecting part of the fixing device to the rear surface of the connecting part when the side edge trim is assembled is at least partially prevented compared to a fixing device that is not provided with the anti-rotation member.

[0038] When the side edge trim is mounted on the door frame rail, the anti-rotation member deforms, in particular is compressed, against the door frame and / or the rear face of the door frame rail, thereby preventing the connecting part of the fixing device from tilting towards the door frame. This deformation is, of course, elastic: when the side edge trim is removed from its door frame rail, the anti-rotation member returns to its normal configuration, in which it maintains a non-zero clearance between itself and the door frame, as described above.

[0039] The fixing device according to the first aspect of the present invention is capable of fixing the side edge trim due to the fixing opening of the connecting part. The side edge trim includes a fixing component that cooperates with the fixing opening of the connecting part of the fixing device according to the first aspect of the present invention. For example, the fixing opening of the connecting part and the fixing component cooperate by virtue of complementary shapes. The fixing component of the side edge trim is located on a rear face of the side edge trim, which is opposite to a front face of the side edge trim, the front face being the face intended to be visible on the motor vehicle.

[0040] Due to the fixing part of the connecting element, the fixing device according to the first aspect of the invention is fixed to the door frame slide rail, which is itself fixed to the door frame. The fixing part of the connecting element cooperates with the door frame slide rail, for example, by means of complementary shapes.

[0041] In the motor vehicle according to the third aspect of the present invention, the longitudinal body of the door frame slide rail defines a fixed frame along the door frame to which it is fixed, so as to guide the movement of the window mounted on the door frame.

[0042] The side edge trim forms a plate-like element extending at least partially along the side edge of the door frame. Thus, when the side edge trim, which is particularly aesthetically pleasing, is positioned on a motor vehicle according to the third aspect of the invention, the fastening device according to the first aspect of the invention is concealed.

[0043] Various embodiments of the invention are provided which integrate the different optional features set out herein in all possible combinations. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] Of course, the features, variants and different embodiments of the invention can be combined with one another in various combinations, provided that they are not incompatible or mutually exclusive. In particular, it is conceivable that a variant of the invention comprises only a selection of the features described below separately from the other features described, provided that this selection of features is sufficient to confer a technical advantage or to distinguish the invention from the prior art.

[0051] In particular, all variants and all embodiments described can be combined with one another, provided nothing prevents this combination from a technical point of view.

[0052] In the figures, elements common to several figures retain the same reference numerals.

[0053] Figure 1 A motor vehicle 1 is shown equipped with a fixing device 2 according to the first aspect of the invention, which is housed in a door frame rail 3 according to the second aspect of the invention. The terms "upper", "lower", "front" and "rear" are used hereinafter in this description relative to the positioning of the elements thus defined in the motor vehicle 1.

[0054] The motor vehicle 1 comprises two side doors 4 on at least one of its sides (i.e. a front door 4 and a rear door 4), each of which is housed in a door frame 5 ( Figure 1 Each door frame 5 comprises an upper edge 6 which is arranged horizontally or substantially horizontally along a roof 7 of the motor vehicle 1. The upper edge 6 of the door frame 5 is vertically extended into a side edge 8 which is arranged between the two side doors 4 of the motor vehicle 1.

[0055] The motor vehicle 1 further comprises a side edge trim 9 which is positioned along the side edge 8 of the door frame 5 and serves to aesthetically mask the side edge 8 of the door frame 5. The side edge trim 9 is thus located between the two side doors 4 of the motor vehicle 1. To this end, the side edge trim 9 is fixed integrally to the door frame rail 3 by means of a fixing device 2 for the trim, as will be described in detail below.

[0056] Figure 2The door frame 5 of one of the side doors 4 of the motor vehicle 1 is shown (seen from the outside of the motor vehicle 1 ), the door frame 5 being equipped with a side edge trim 9 .

[0057] Figure 2 The upper edge 6 of the door frame 5 and the side edge 8 of the door frame 5 are shown, which together accommodate the door frame slide rail 3. Figure 2 As can be seen above, the fixing device 2 connects the door frame slide rail 3 to the side edge trim 9 , the fixing device 2 being shown in dashed lines because it is concealed behind the side edge trim 9 when viewed from the outside of the motor vehicle 1 .

[0058] The fixing device 2 according to the first aspect of the invention comprises a connecting part 10 .

[0059] The side edge trim 9 is integrally connected to the connecting part 10 of the fixing device 2 via a fixing opening 11 in the connecting part 10. Fixing opening 11 is provided in a contact surface 12 of the connecting part 10, onto which the side edge trim 9 is attached. Fixing opening 11 is located on the side of the lower surface 13 of the connecting part 10, which is not covered by the door frame rail 3. Fixing opening 11 is provided so as to pass through both sides of the connecting part 1. Fixing opening 11 generally has a trapezoidal shape.

[0060] The connecting part 10 of the fixing device 2 is fixed integrally to the door frame rail 3 by means of a fixing part 14. The fixing part 14 of the door frame rail 3 is arranged on the side of the upper surface 15 of the connecting part 10. The upper surface 15 of the connecting part 10 is opposite to the lower surface 13 of the connecting part 10.

[0061] The fixing device 2 includes an anti-rotation member 16. When the connecting part 10 is mounted on the door frame slide rail 3, the anti-rotation member 16 is received between the door frame slide rail 3 and the door frame 5. The connecting part 10 is arranged in an intermediate position between the side edge trim 9 and the anti-rotation member 16.

[0062] like Figure 2 As shown above, the connecting element 10 of the fastening device 2 according to the first aspect of the present invention has a trapezoidal general shape, with its upper face 15 being larger than its lower face 13. The fastening opening 11 for fastening the trim, which is included in the connecting element 10, also has a trapezoidal shape. The anti-rotation member 16 itself has the shape of a parallelepiped and is arranged between the fastening opening 11 and the upper face 15 of the connecting element 10. The anti-rotation member 16 and the fastening opening 11 for fastening the trim are laterally centered relative to the connecting element 10.

[0063] Figure 3The door frame 5 is shown viewed from the interior of the motor vehicle 1 so that the side edge trim 9 is at the rear relative to the fastening device 2 according to the first aspect of the invention.

[0064] The fixing device 2 is located at the junction between the side edge 8 of the door frame 5 and the upper edge 6 of the door frame 5. Figure 3 In FIG. 5 , the door frame 5 is not shown to reveal the fixing device 2 .

[0065] exist Figure 3 , the connecting element 10 is viewed from the side with its rear face 17, which is opposite the contact face 12. The rear face 17 is intended to be oriented toward the door frame 5. The connecting element 10 is integrally connected to an anti-rotation member 16, which protrudes from the rear face 17 of the connecting element 10. The connecting element 10 is penetrated by a fixing opening 11.

[0066] Figure 4 Along Figure 3 The longitudinal section AA shown shows the arrangement of the fixing device 2 relative to the door frame 5 according to the first aspect of the invention. In particular, Figure 4 The attachment device 2 is shown cooperating with the door frame rail 3 on the one hand and the side edge trim 9 on the other hand. The attachment device 2 is accommodated in a side receptacle 18 of the side door 4. The side receptacle 18 is delimited by the side edge trim 9, the door frame rail 3 and the side edge 8 of the door frame 5.

[0067] At section AA, the side edge 8 of the door frame 5 is in the form of a bimetallic plate that participates in the structure of the side door 4 facing the side edge trim 9. The door frame slide rail 3 includes a body 19 that extends longitudinally along the door frame 5 and is integrally connected to the body by a connecting part 10.

[0068] The connecting part 10 comprises a fixing part 14, by which the connecting part 10 and the door frame slide rail 3 are connected as one piece. In this case, the fixing part 14 of the connecting part 10 is complementary to the main body 19 of the door frame slide rail 3 and is inserted therein.

[0069] The fastening opening 11 extends through the connecting element 10 from its contact surface 12 to its rear surface 17. In this case, the fastening opening 11 enables the connecting element 10 to be integrally connected to the side edge trim 9. To this end, the side edge trim 9 includes a tongue 20 that is configured to rest against the fastening opening 11. This advantageous configuration not only stabilizes the side edge trim 9 in its assembled position but also allows the door frame rail 3 and the side edge trim 9, which are located on the same side of the motor vehicle 1, to be aligned.

[0070] The anti-rotation member 16 is advantageously overmolded on the connecting part 10. Figure 4 As can be seen from the section AA, the anti-rotation member 16 and the connecting part 10 of the fixing device 2 are perfectly nested in each other: the anti-rotation member 16 is located between the upper face 15 of the connecting part 10 and the lower face 13 of the connecting part 10 on the one hand, and on the other hand protrudes from the rear face 17 of the connecting part 10 and the fitting face 12 at the section AA position.

[0071] When the anti-rotation member 16 is overmolded on the connection part 10, the anti-rotation member 16 comprises a functional opening 21 laterally centered on the anti-rotation member 16. This functional opening 21 facilitates demoulding of the anti-rotation member 16, enabling material savings and making the fixing device 2 lightweight.

[0072] Anti-rotation member 16 of fixture 2 extends toward door frame 5, resulting in a non-zero functional gap 22 between anti-rotation member 16 and door frame 5 when side edge trim 9 is not assembled. In this case, anti-rotation member 16 partially abuts the bimetallic sheet of door frame 5 at abutment area 23 of anti-rotation member 16, reducing functional gap 22. Abutment area 23 of anti-rotation member 16 abuts against door frame 5 under the force exerted by the attachment of side edge trim 9 to fixture 2, indicated by solid arrow 24. This abutment against door frame 5 limits the fixture 2 from tilting backward. Indeed, when side edge trim 9 engages connecting element 10, fixture 2 quickly comes into contact with door frame 5. Rearward tilting occurs in the plane of section AA, as indicated by arrow arc 26 around center 25.

[0073] In the absence of the anti-rotation member 16, the fixing device 2 will continue its own travel and reach the position as shown in FIG. Figure 4 The position shown above is rearward, that is, closer to the door frame 5.

[0074] Figure 5 The connecting element 10 is shown separated from the fixing device 2. The connecting element 10 is viewed from the side where its contact surface 12 is located, and the upper face 15 and the lower face 13 of the connecting element are distinguished.

[0075] The fastening opening 11 is located on the contact surface 12 of the connecting element 10. In the embodiment shown in the drawings, the fastening opening 11 has a general trapezoidal shape. Furthermore, the fastening opening 11 extends through the connecting element 10 from the contact surface 12 to the rear face 17 of the connecting element 10. The fastening opening 11 cooperates with the side edge trim 9 to allow it to be fastened to the connecting element 10, in particular by means of a complementary fit.

[0076] The contact surface 12 of the connection element 10 further comprises two ribs 28, which are parallel to one another and extend longitudinally between the fixing opening 11 and the upper face 15 of the connection element 10. The two ribs 28 protrude from the contact surface 12 of the connection element 10. Each rib 28 extends longitudinally beyond the upper face 15 of the connection element 10 and forms a lug 27 for cooperating with the anti-rotation member 16 in order to facilitate the fixing of the anti-rotation member on the connection element 10.

[0077] The connection part 10 comprises functional orifices 29 which participate in the bonding between the connection part 10 and the anti-rotation member 16 during overmolding of the connection part 10 and the anti-rotation member 16 . Figure 4 One of the functional openings 29 is still visible, into which the material from the anti-rotation member 16 is filled.

[0078] In summary, the present invention relates to a fastening device 2 for fastening a side edge trim 9 to a door frame 5 of a motor vehicle 1. The fastening device 2 includes a connecting element 10 configured to secure the side edge trim 9 to a door frame rail 3. The fastening device 2 according to the present invention is equipped with an anti-rotation member 16, which is fixed integrally with the connecting element 10 and secures the relative position of the side edge trim 9 and the door frame rail 3. The anti-rotation member 16 thus forms a stop configured to limit tilting of the fastening device 2 relative to the door frame rail 3 when the side edge trim 9 is secured to the connecting element 10.

[0079] Of course, the present invention is not limited to the embodiments just described, and many modifications may be made to these embodiments without departing from the scope of the present invention. In particular, the different implementation features, embodiments, implementation variants, and embodiments of the present invention may be combined with one another in various combinations, provided that they are not incompatible or mutually exclusive. In particular, all the variants and embodiments described above may be combined with one another.
