TITRE : Dispositif de fixation d'un élément d'un véhicule automobile TITLE: Device for fixing a component of a motor vehicle
La présente invention concerne un dispositif de fixation d'un élément de protection sur un organe d'un véhicule automobile. The present invention relates to a device for fixing a protective element to a component of a motor vehicle.
Un véhicule automobile est de manière habituelle équipé de nombreux caches qui possèdent des fonctions variées. A motor vehicle is usually equipped with numerous covers which have various functions.
Il existe notamment des caches en matière fibreuse qui ont notamment des propriétés acoustiques et/ou thermiques ; ces caches se trouvent, en particulier, dans le compartiment moteur et viennent encapsuler des organes du moteur tel que, par exemple, le carter de courroie d'accessoire ou le cache moteur. On peut trouver également des caches en matière fibreuse au niveau des pare boues. There are in particular covers made of fibrous material which in particular have acoustic and / or thermal properties; these covers are found, in particular, in the engine compartment and come to encapsulate engine components such as, for example, the accessory belt cover or the engine cover. One can also find covers of fibrous material at the level of the mud shields.
La pose d'un cache - fibreux ou non - dans un compartiment moteur peut être une opération délicate à effectuer car la pose de dispositifs de fixation tel que rivets, vis, clips... peut être complexe compte tenu de l'encombrement général d'un compartiment moteur d'un véhicule actuel. The installation of a cover - fibrous or not - in an engine compartment can be a delicate operation to carry out because the installation of fixing devices such as rivets, screws, clips ... can be complex given the general size of the vehicle. 'an engine compartment of a current vehicle.
Dans ce contexte technique, un but de l'invention est d'améliorer la fixation d'un élément tel qu'un cache sur un organe d'un véhicule. In this technical context, an aim of the invention is to improve the fixing of an element such as a cover on a component of a vehicle.
Selon un premier aspect, l'invention concerne un dispositif de fixation d'un élément de protection sur un organe d'un véhicule automobile caractérisé en ce que le dispositif comprend : un insert comprenant : o un corps tubulaire ayant une surface d'appui dans laquelle est ménagée une ouverture et, à l'opposé de la surface d'appui, une zone de serrage configurée pour enserrer ledit élément de protection ; o une lame hélicoïdale élastique pouvant occuper une position déployée dans laquelle la lame hélicoïdale est éloignée axialement du corps pour permettre l'engagement de la lame hélicoïdale dans une ouverture pratiquée dans l'élément de protection et une position fléchie dans laquelle la lame hélicoïdale est rapprochée du corps, o la zone de serrage étant délimitée par une collerette débordant radialement du corps et par la lame hélicoïdale lorsque celle-ci est en position fléchie, une vis introduite dans l'insert par l'ouverture, présentant une tête configurée pour venir en appui contre la surface d'appui du corps et un filetage configuré pour venir s'engager dans un filetage complémentaire ménagé dans l'organe du véhicule automobile, l'engagement du filetage de la vis dans le filetage de la pièce produisant une flexion de la lame hélicoïdale pour amener la lame hélicoïdale élastique dans une position parallèle à la collerette. According to a first aspect, the invention relates to a device for fixing a protective element on a member of a motor vehicle, characterized in that the device comprises: an insert comprising: a tubular body having a bearing surface in which is formed an opening and, opposite the bearing surface, a clamping zone configured to grip said protection element; o an elastic helical blade which can occupy a deployed position in which the helical blade is axially removed from the body to allow the engagement of the helical blade in an opening made in the protection element and a flexed position in which the helical blade is brought together of the body, the clamping zone being delimited by a flange projecting radially from the body and by the helical blade when the latter is in the flexed position, a screw introduced into the insert through the opening, having a head configured to come in bearing against the bearing surface of the body and a thread configured to engage in a complementary thread formed in the component of the vehicle automotive, the engagement of the thread of the screw in the thread of the part producing a flexion of the helical blade to bring the resilient helical blade into a position parallel to the collar.
L'invention fournit ainsi un dispositif de fixation d'un élément de protection tel qu'un cache sur un organe d'un véhicule qui est extrêmement facile à mettre en œuvre par un utilisateur sur une chaîne d'assemblage. The invention thus provides a device for fixing a protective element such as a cover on a component of a vehicle which is extremely easy to use by a user on an assembly line.

Selon un deuxième aspect, l'invention concerne un élément de protection destiné à être fixé sur un organe d'un véhicule automobile par un dispositif comme précédemment indiqué, l'élément de protection comprenant une ouverture circulaire à laquelle est accolée une fente radiale dans laquelle est engagée la lame hélicoïdale. According to a second aspect, the invention relates to a protection element intended to be fixed to a member of a motor vehicle by a device as previously indicated, the protection element comprising a circular opening to which is contiguous a radial slot in which the helical blade is engaged.
Selon une possibilité de réalisation, l'élément de protection présente une zone encaissée dans laquelle sont disposées l'ouverture circulaire et la fente radiale. According to one embodiment, the protection element has a boxed area in which the circular opening and the radial slot are arranged.

For its proper understanding, the invention is described with reference to the appended figures showing, by way of nonlimiting examples, one embodiment of the invention.

[Fig 10] est une extraction de la figure 8 montrant le corps de l'insert,[Fig 10] is an extraction of Figure 8 showing the body of the insert,
[Fig 11] est une vue en coupe de l'insert engagé sur un élément de protection. [Fig 11] is a sectional view of the insert engaged on a protection element.
Comme le montre la figure 2, le dispositif de fixation comprend essentiellement deux éléments à savoir un insert 2 qui est, de préférence, obtenu par un moulage de matière plastique, l'insert 2 recevant une vis 3. As shown in FIG. 2, the fixing device essentially comprises two elements, namely an insert 2 which is preferably obtained by molding of plastic material, the insert 2 receiving a screw 3.
La vue en coupe de la figure 3 permet d'apprécier plus précisément la structure de l'insert 2 de fixation. The sectional view of FIG. 3 makes it possible to appreciate more precisely the structure of the fixing insert 2.
L'insert 2 se compose ainsi d'un corps 5 de forme générale tubulaire et d'une lame hélicoïdale 6 élastique. The insert 2 thus consists of a body 5 of generally tubular shape and of an elastic helical blade 6.
Sur sa face externe, le corps 5 présente, à une première extrémité, une surface d'appui 7 dans laquelle débouche une ouverture 8. On its outer face, the body 5 has, at a first end, a bearing surface 7 into which an opening 8 emerges.
On note également la présence d'une collerette 10 qui déborde radialement et de nervures 11 qui, dans le cas présent, sont au nombre de quatre ; les nervures 11 s'étendent selon des génératrices du corps 5 depuis la collerette 10 vers la surface d'appui 7. We also note the presence of a collar 10 which projects radially and ribs 11 which, in the present case, are four in number; the ribs 11 extend along generatrices of the body 5 from the collar 10 towards the bearing surface 7.
Au niveau de sa seconde extrémité, le corps 5 est pourvu d'une jupe tubulaire 13 sur laquelle est fixée la lame hélicoïdale 6. At its second end, the body 5 is provided with a tubular skirt 13 on which the helical blade 6 is fixed.
Comme on peut le voir, par exemple, sur la figure 3, l'insert 2 présente un pont de matière 14 qui s'étend radialement depuis la jupe tubulaire 13 et qui relie la lame hélicoïdale 6 élastique à cette même jupe tubulaire 13. As can be seen, for example, in FIG. 3, the insert 2 has a bridge of material 14 which extends radially from the tubular skirt 13 and which connects the elastic helical blade 6 to this same tubular skirt 13.
La lame hélicoïdale 6 élastique est venue de moulage avec le corps 5 de telle sorte que, au repos, la lame hélicoïdale 6 élastique est dans une configuration qui la maintient éloignée axialement de la jupe tubulaire 13, tel que cela apparaît, par exemple, sur les figures 3, 7 et 8. Au niveau de sa surface interne, le corps 5 est doté au niveau de sa première extrémité d'un retour radial 15 qui forme un rétrécissement dans sa cavité interne. The resilient helical blade 6 is molded with the body 5 such that, at rest, the resilient helical blade 6 is in a configuration which keeps it axially distant from the tubular skirt 13, as appears, for example, on Figures 3, 7 and 8. At its internal surface, the body 5 is provided at its first end with a radial return 15 which forms a constriction in its internal cavity.
Comme cela apparaît plus particulièrement à la figure 4, le retour radial 15 est de plus pourvu de nervures 17 qui sont orientées vers le centre de l'ouverture 8. On comprendra plus loin la fonction des nervures 17 qui, dans l'exemple représenté, sont au nombre de trois. As appears more particularly in FIG. 4, the radial return 15 is moreover provided with ribs 17 which are oriented towards the center of the opening 8. The function of the ribs 17 which, in the example shown, will be understood below. are three in number.
On peut également remarquer que la géométrie interne du corps 5 dans sa partie qui s'ouvre vers sa seconde extrémité est configurée en tronc de cône. It can also be noted that the internal geometry of the body 5 in its part which opens towards its second end is configured as a truncated cone.
Le corps 5 est donc destiné à recevoir une vis 3. Celle-ci présente une tête 18 qui, dans l'exemple de réalisation montré à la figure 2 par exemple, est du type hexagonal. La tête de vis 18 présente également une embase 19. Accolé à l'embase 19, la vis 3 possède un fût cylindrique 20 qui est lui-même relié à une collerette 21 qui déborde radialement. Puis la vis 3 se poursuit par un filetage 22 et enfin un cône d'extrémité 23. The body 5 is therefore intended to receive a screw 3. The latter has a head 18 which, in the embodiment shown in FIG. 2 for example, is of the hexagonal type. The screw head 18 also has a base 19. Attached to the base 19, the screw 3 has a cylindrical shank 20 which is itself connected to a flange 21 which projects radially. Then the screw 3 continues with a thread 22 and finally an end cone 23.
Le dispositif de fixation est du type imperdable dans la mesure où la vis 3 qui est donc engagée au niveau de l'ouverture du corps 5, doit être passée en force pour écarter les trois nervures 17 qui ont pour fonction de rendre la vis 3 imperdable. The fixing device is of the captive type insofar as the screw 3 which is therefore engaged at the level of the opening of the body 5, must be passed by force to separate the three ribs 17 which have the function of making the screw 3 captive. .
La collerette 21 est, en effet, d'un diamètre légèrement supérieur au diamètre défini par les extrémités libres des trois nervures 17 d'imperdabilité. The collar 21 is, in fact, of a diameter slightly greater than the diameter defined by the free ends of the three ribs 17 of losslessness.
Le sous ensemble formé par l'insert 2 et la vis 3 est donc un sous ensemble unitaire qui peut être conditionné et manipulé à loisir dans la mesure où la vis 3 et l'insert 2 sont liés sans risque de séparation. The sub-assembly formed by the insert 2 and the screw 3 is therefore a unitary sub-assembly which can be packaged and handled at will to the extent that the screw 3 and the insert 2 are linked without risk of separation.
Le dispositif de fixation 1 ainsi défini est destiné à venir assurer la fixation d'un élément de protection 26 qui est, de préférence, un élément fibreux réalisé en un matériau thermoformé, à base de fibres polyester, fibres de verre, ou fibres de bois avec ou sans polyuréthane. The fixing device 1 thus defined is intended to ensure the fixing of a protective element 26 which is preferably a fibrous element made of a thermoformed material, based on polyester fibers, glass fibers, or wood fibers. with or without polyurethane.
Il peut s'agir donc d'un carter de protection, par exemple pour une chaîne de distribution comme on peut le voir sur la figure 1, d'un carter moteur, d'un pare boue, etc... It may therefore be a protective casing, for example for a timing chain as can be seen in FIG. 1, an engine casing, a mudguard, etc ...
La particularité de l'élément de protection 26 est que l'ouverture qui va permettre de le fixer sur un organe 27 d'un véhicule automobile présente une ouverture circulaire 24 à laquelle est accolée une fente radiale 25. La figure 5 illustre particulièrement cette disposition de l'invention. The particularity of the protective element 26 is that the opening which will allow it to be fixed to a member 27 of a motor vehicle has a circular opening 24 to which is contiguous a radial slot 25. FIG. 5 particularly illustrates this arrangement. of the invention.
Les figures 5 et 6 font également ressortir un avantage particulier de l'invention qui est que le site de fixation de l'élément de protection peut être disposé dans une zone encaissée, c'est-à-dire une zone qui se situe en retrait de la surface extérieure de l'élément de protection 26. Figures 5 and 6 also show a particular advantage of the invention which is that the site of attachment of the protective element can be arranged in a boxed area, that is to say an area which is set back from the outer surface of the protective element 26.
Il s'agit d'une configuration relativement classique qui permet de protéger le dispositif de fixation, mais qui rend l'accès à ce même dispositif de fixation relativement complexe notamment dans un environnement de capot moteur particulièrement encombré. This is a relatively conventional configuration which makes it possible to protect the fixing device, but which makes access to this same fixing device relatively complex, especially in a particularly crowded engine cover environment.
Dans le cadre de l'invention, la fixation de l'élément de protection 26 se fait de manière particulièrement aisée puisqu'un opérateur saisit un dispositif de fixation 1, l'engage dans l'ouverture pratiquée dans l'élément de protection 26. In the context of the invention, the fixing of the protection element 26 is done in a particularly easy manner since an operator grasps a fixing device 1, engages it in the opening made in the protection element 26.
Pour cela, l'extrémité libre de la lame hélicoïdale 6 élastique est engagée dans la fente radiale 25 puis l'utilisateur effectue une rotation du corps 5 tubulaire ; pour cela, il est aidé par la présence des nervures 11. For this, the free end of the elastic helical blade 6 is engaged in the radial slot 25 then the user rotates the tubular body 5; for this, it is helped by the presence of ribs 11.
Cette rotation s'effectue jusqu'à ce que le corps 5 de fixation vienne en butée du pont de matière qui relie la lame hélicoïdale 6 élastique au corps 5. This rotation takes place until the fixing body 5 comes into abutment against the material bridge which connects the elastic helical blade 6 to the body 5.
Dans cette configuration, le dispositif de fixation 1 est solidarisé sur l'élément de protection 26, celui-ci pouvant être manipulé pour être mis en position dans un véhicule sur son site de montage final. In this configuration, the fixing device 1 is secured to the protective element 26, the latter being able to be manipulated in order to be placed in position in a vehicle on its final assembly site.
Par des moyens de vissage classiques, l'utilisateur peut alors visser la vis 3 dans l'organe 27 du véhicule de sorte que l'élément de protection 26 soit fixé. By conventional screwing means, the user can then screw the screw 3 into the member 27 of the vehicle so that the protective element 26 is fixed.
La figure 7 illustre la phase d'accostage de l'élément de protection doté d'un dispositif de fixation. La vis 3 est alors présentée en regard d'un filetage 29 pratiqué dans l'organe du véhicule. FIG. 7 illustrates the docking phase of the protection element provided with a fixing device. The screw 3 is then presented opposite a thread 29 formed in the component of the vehicle.
La figure 8 montre la lame hélicoïdale 6 dans sa configuration déployée.Figure 8 shows the helical blade 6 in its deployed configuration.
Après l'opération de vissage, on voit, à la figure 9, la lame hélicoïdale 6 dans sa position fléchie qui forme avec la collerette 10, une zone de serrage de l'élément de protection 26. After the screwing operation, we see, in Figure 9, the helical blade 6 in its flexed position which forms with the collar 10, a clamping area of the protective element 26.
La figure 10 montre l'insert 2 dans cette configuration, la lame hélicoïdale 6 élastique étant fléchie et délimitant, avec la collerette 10, un espace annulaire qui va emprisonner l'élément de protection 26. FIG. 10 shows the insert 2 in this configuration, the elastic helical blade 6 being bent and delimiting, with the collar 10, an annular space which will trap the protective element 26.
La figure 11 montre une disposition intéressante de l'invention dans laquelle la surface intérieure du corps 5 tubulaire qui peut être tronconique permet une orientation de la vis 3 selon une plage angulaire relativement importante qui peut être de l'ordre de 70 degrés et qui, combinée à l'extrémité conique de la vis 3, permet de facilement mettre l'élément de protection en regard de trous filetés 29 pratiqués dans l'organe du véhicule. L'invention fournit ainsi un dispositif de fixation d'un élément de protection tel qu'un cache sur un organe d'un véhicule qui est extrêmement facile à mettre en œuvre par un utilisateur sur une chaîne d'assemblage. FIG. 11 shows an interesting arrangement of the invention in which the inner surface of the tubular body 5 which may be frustoconical allows orientation of the screw 3 over a relatively large angular range which may be of the order of 70 degrees and which, combined with the conical end of the screw 3, allows the protection element to be easily placed opposite threaded holes 29 made in the vehicle component. The invention thus provides a device for fixing a protective element such as a cover on a component of a vehicle which is extremely easy to use by a user on an assembly line.
On note de plus que le dispositif de fixation selon l'invention est entièrement réversible. En d'autres termes, il peut être séparé de l'élément de protection soit pour une réparation, soit en fin de vie du véhicule pour être recyclé. It is further noted that the fixing device according to the invention is fully reversible. In other words, it can be separated from the protection element either for repair or at the end of the vehicle's life in order to be recycled.
