Description

PROFILE D'ETANCHEITE POXJR OUVRANT OU ENCADREMENT D'OUVERTURE D'UN VEHICULE AUTOMOBILEOPENING POXJR SEALING PROFILE OR OPENING FRAME OF A MOTOR VEHICLE

-La présente invention concerne un nouveau profilé d'étanchéité pour ouvrant ou encadrement d'ouverture d'un véhicule automobile. Elle concerne plus particulièrement un profilé de ce type à section transversale en U ou en Ω, destiné à coiffer et à pincer une partie saillante d'un tel ouvrant ou d'un tel encadrement d'ouverture.The present invention relates to a new sealing profile for opening or opening frame of a motor vehicle. It relates more particularly to a profile of this type having a cross section in U or in Ω, intended to cap and pinch a projecting portion of such an opening or such an opening frame.

Les profilés de ce type ont essentiellement une fonction d'étanchéité et parfois un rôle décoratif, mais ils sont aussi souvent attenants à un ou plusieurs autres profilés tubulaires en un matériau déformable élastiquement, destinés à être comprimés entre un encadrement de porte et cette porte, lorsqu'elle est en position de fermeture, pour assurer l'étanchéité de l'habitacle d'un véhicule automobile. Les profilés formant pince auxquels s'intéresse la présente invention sont bien connus dans la technique et ils sont généralement réalisés en un élastomère ou un plastomère, dans lequel est habituellement noyée une armature de renfort, métallique ou en matière plastique. Cette armature est destinée à renforcer le profilé et à améliorer ses qualités de fixation.The profiles of this type have essentially a sealing function and sometimes a decorative role, but they are also often attached to one or more other tubular profiles in a resiliently deformable material, intended to be compressed between a door frame and the door, when in the closed position, to seal the passenger compartment of a motor vehicle. The forging profiles to which the present invention is concerned are well known in the art and are generally made of an elastomer or plastomer, in which is usually embedded a reinforcing reinforcement, metal or plastic. This reinforcement is intended to strengthen the profile and improve its fastening qualities.

De telles armatures sont malheureusement coûteuses et elles accroissent sensiblement le poids des profilés qu'elles équipent. Aussi a-t-il été déjà proposé de les supprimer en choisissant, pour réaliser le profilé, un élastomère ou un plastomère propre à lui conférer une rigidité comparable à celle des profilés à armature de la technique connue.Such frames are unfortunately expensive and they significantly increase the weight of the profiles they equip. It has already been proposed to eliminate them by choosing, in order to make the profile, an elastomer or a plastomer capable of giving it a rigidity comparable to that of the reinforcement sections of the known technique.

Il s'avère toutefois nécessaire, dans ce cas, d'augmenter l'épaisseur de certaines parties du profilé, pour obtenir une tenue suffisante de celui-ci sur les feuillures des ouvrants ou des encadrements d'ouverture d'automobiles auxquelles il est associé (voirHowever, it is necessary, in this case, to increase the thickness of certain parts of the profile, to obtain sufficient strength thereof on the rabbets of the opening or the opening frames of automobiles to which it is associated (see

FR 2 797 930 A ou FR 2 824 611 A, par exemple).FR 2 797 930 A or FR 2 824 611 A, for example).

Par ailleurs, pour obtenir la rigidité désirée, on doit utiliser des élastomères ou des plastomères semi-durs, dont généralement la masse spécifique est relativement élevée, ce qui, combiné avec les augmentations d'épaisseur qui viennent d'être mentionnées, se traduit par un accroissement du poids du profilé, pouvant annuler le gain de poids résultant de l'absence de l'armature usuelle, surtout si celle-ci est légère.Furthermore, to obtain the desired rigidity, it is necessary to use elastomers or semi-hard plastomeres, generally whose specific mass is relatively high, which, combined with the increases in thickness just mentioned, results in an increase in the weight of the profile, which can cancel the gain of weight resulting from the absence of the usual reinforcement, especially if it is light.

L'invention vise à remédier à cet inconvénient en proposant un profilé formant pince et dépourvu d'armature de renfort, ce profilé comportant un corps en un élastomère ou plastomère normalement semi-dur, dont les caractéristiques sont telles que le profilé présente les propriétés mécaniques recherchées et, à l'intérieur de ce corps, au moins une partie creuse, vide ou emplie d'un matériau de remplissage, cette partie creuse participant, de par sa forme ou en raison de la nature du matériau de remplissage éventuellement présent, aux fonctions du profilé, mais étant destinée essentiellement, soit parce qu'elle est dépourvue de matériau de remplissage, soit parce que ce matériau a une masse spécifique inférieure à celle de l' élastomère ou du plastomère, à rendre la masse spécifique moyenne apparente du profilé inférieure à celle d'un profilé usuel présentant des caractéristiques analogues, mais comportant une armature de renfort.The invention aims to remedy this drawback by proposing a profile forming a clamp and devoid of reinforcing reinforcement, this profile comprising a body made of a normally semi-hard elastomer or plastomer, whose characteristics are such that the profile has the mechanical properties. and, inside the body, at least one hollow, empty or filled part of a filling material, this hollow part participating, by its shape or because of the nature of the filling material that may be present, to functions of the profile, but being essentially intended, either because it is devoid of filling material, or because this material has a lower density than that of the elastomer or plastomer, to make the apparent average density of the profile less than that of a conventional section having similar characteristics, but having a reinforcing reinforcement.

L'invention a par conséquent pour objet un profilé d'étanchéité pour ouvrant ou encadrement d'ouverture d'un véhicule automobile, ce profilé présentant une section transversale en U ou en Ω et étant destiné à coiffer en la pinçant une partie saillante de l'ouvrant ou de l'encadrement, ce profilé comprenant un corps à section transversale en U ou en Ω, dépourvu d'armature de renfort et constitué d'un élastomère ou d'un plastomère dont les propriétés physiques, et notamment la dureté, sont telles que le profilé présente la rigidité désirée, ce profilé étant caractérisé en ce que le corps comporte une ou des parties creuses, éventuellement emplies d'un matériau de remplissage présentant une masse spécifique plus faible que celle de l'élastomère ou du plastomère constituant le corps.The invention therefore relates to a sealing profile for opening or opening frame of a motor vehicle, this section having a cross section in U or Ω and being intended to cap by pinching a projecting portion of the opening or framing, this profile comprising a body of U or Ω cross-section, devoid of reinforcing reinforcement and consisting of an elastomer or a plastomer whose physical properties, and in particular the hardness, are such that the profile has the desired rigidity, this profile being characterized in that the body comprises one or hollow portions, optionally filled with a filler material having a lower specific mass than that of the elastomer or plastomer constituting the body.

L'élastomère ou le plastomère constituant le corps du profilé a de préférence une dureté comprise entre 35 et 45 SHORE A. On peut utiliser, par exemple, un E.P.D.M. ou du polypropylène, seuls ou en mélange.The elastomer or plastomer constituting the body of the profile preferably has a hardness of between 35 and 45 SHORE A. It is possible to use, for example, an E.P.D.M. or polypropylene, alone or in admixture.

Le matériau constituant le matériau remplissant éventuellement les parties creuses du corps en élastomère ou en plastomère est avantageusement un matériau cellulaire rigide ou à flexibilité limitée, à cellules ouvertes ou fermées, notamment un E.P.D.M. cellulaire ou une mousse thermoplastique, par exemple styrènique, uréthanique ou oléfinique. Ce matériau a, de préférence, une masse spécifique comprise entre 0,30 et 0,80 g/ cm3 et, de préférence, de l'ordre de 0,50 g/ cm3.The material constituting the material that optionally fills the hollow parts of the body made of elastomer or plastomer is advantageously a rigid or limited-flexibility cellular material with open or closed cells, in particular a cellular EPDM or a thermoplastic foam, for example styrene, urethane or olefin. This material preferably has a density of between 0.30 and 0.80 g / cm 3 and preferably of the order of 0.50 g / cm 3 .

Ce matériau est de préférence choisi de manière à pouvoir être recyclé facilement, en fin d'utilisation du profilé. Outre la réduction de son poids, le profilé conforme à l'invention présente l'avantage d'être moins coûteux que les profilés à armatures de renfort de la technique antérieure, car ces armatures, qui présentent souvent des découpes sophistiquées, augmentent sensiblement le coût des profilés qu'elles équipent et accroissent aussi les coûts de recyclage, en fin de vie du profilé.This material is preferably selected so as to be easily recycled at the end of use of the profile. In addition to reducing its weight, the profile according to the invention has the advantage of being less expensive than the reinforcement reinforcement profiles of the prior art, because these reinforcements, which often have sophisticated cutouts, significantly increase the cost. profiles they equip and also increase recycling costs, end of life of the profile.

En outre, les armatures usuelles comportent souvent des lamelles latérales (cas des armatures dites "en arête de poisson"), qui provoquent des déformations superficielles plus ou moins visibles, mais toujours présentes sur le profilé, désignées dans la technique par le nom évocateur de "côtes de cheval", que l'on ne retrouve pas, bien entendu, dans le profilé conforme à l'invention.In addition, the usual reinforcements often include lateral lamellae (in the case of reinforcements called "fishbone"), which cause superficial deformations more or less visible, but still present on the profile, designated in the art by the evocative name of "horse ribs", which is not found, of course, in the section according to the invention.

Le corps du profilé peut comporter une unique partie creuse emplie d'un matériau à masse spécifique réduite et présentant une section transversale en U, analogue à celle du profilé. Le corps du profilé peut aussi comporter deux parties creusesThe body of the profile may comprise a single hollow portion filled with a reduced specific mass material and having a U-shaped cross section, similar to that of the profile. The body of the profile can also comprise two hollow parts

(ou davantage) emplies d'un matériau à masse spécifique réduite, et s'étendant chacune dans une aile et une partie de la base en U de ce corps, lesdites deux parties situées dans la base du corps étant séparées par une ou plusieurs parties formant cloisons, qui renforcent le profilé, en particulier dans les parties à forte courbure de la feuillure qu'il est destiné à équiper.(or more) filled with a reduced mass material, and each extending into a wing and a portion of the U-shaped base thereof, said two parts located in the base of the body being separated by one or more parts forming partitions, which reinforce the profile, in particular in the high curvature parts of the rabbet it is intended to equip.

Dans le cas où le profilé comporte des parties creuses emplies d'air ou d'un autre gaz, mais dépourvues de tout matériau de remplissage, la présence de cloisons sera naturellement bénéfique pour assurer transversalement la stabilité du profilé, surtout dans les parties à forte courbure de la feuillure qu'il est destiné à équiper.In the case where the profile comprises hollow parts filled with air or another gas, but without any filler material, the presence of partitions will naturally be beneficial to transversely ensure the stability of the profile, especially in areas with strong curvature of the rabbet that it is intended to equip.

Ces diverses formes de réalisation vont être décrites ci-après plus en détail, en référence aux dessins annexés, mais elles n'ont naturellement aucun caractère limitatif. Sur les dessins : La figure 1 est une vue en coupe transversale d'un profilé conforme à l'invention, comportant une unique partie en un matériau à masse spécifique réduite, noyée dans le matériau constitutif du corps du profilé ;These various embodiments will be described below in more detail with reference to the accompanying drawings, but they naturally have no limiting character. In the drawings: FIG. 1 is a cross-sectional view of a profile according to the invention, comprising a single part made of a material with reduced specific mass, embedded in the material constituting the body of the profile;

Les figures la et Ib sont des coupes partielles illustrant des modifications locales du profilé de la figure 1 ; La figure 2 est une coupe transversale d'un autre profilé conforme à l'invention, comportant deux parties en un matériau à masse spécifique réduite, disposées chacune dans une aile du corps du profilé dans une partie de la base de ce corps ;Figures la and Ib are partial sections illustrating local modifications of the section of Figure 1; Figure 2 is a cross section of another section according to the invention, comprising two parts of a reduced density mass material, each disposed in a wing of the profile body in a portion of the base of the body;

La figure 3 est une coupe transversale d'un troisième profilé conforme à l'invention, dans lequel des parties évidées dépourvues de matériau de remplissage et séparées par des cloisons de renfort sont ménagées dans les ailes et dans la base du corps du profilé.Figure 3 is a cross section of a third section according to the invention, wherein the recessed portions devoid of filler material and separated by reinforcing partitions are formed in the wings and in the base of the body of the profile.

Le profilé représenté sur la figure 1 comprend un corps creux 1 à section en U, dépourvu d'armature de renfort et constitué ici d'un E.P.D.M. ayant une dureté d'environ 80 à 95 SHORE A et une masse spécifique de 1 à 1,4 g/ cm3. Un tel profilé peut aussi être réalisé en un matériau thermoplastique.The profile shown in FIG. 1 comprises a hollow body 1 with a U-shaped cross-section, devoid of reinforcing reinforcement and consisting here of an EPDM having a hardness of approximately 80 to 95 SHORE A and a specific mass of 1 to 1, 4 g / cm 3 . Such a profile can also be made of a thermoplastic material.

Ce corps 1 est destiné à coiffer en la pinçant une partie saillante d'un ouvrant ou d'un encadrement d'ouverture d'un véhicule automobile et, pour le bloquer en position sur cette partie saillante, de façon connue, une ou des lèvres 2 en E.P.D.M. ou en matériau thermoplastique, d'une dureté ici d'environ 65 SHORE A, font saillie obliquement à partir de la face de chacune des branches du corps 1 en direction de la branche opposée et de la base de ce corps. Pour réduire le poids du profilé, tout en lui conservant une rigidité suffisante, une mousse rigide en élastomère ou en plastomère, d'une masse spécifique de 0,3 à 0,8 g/cm3, est logée dans une partie creuse 3 du corps 1, qui en épouse la forme générale et avec lequel elle est coextrudée. Avec un tel profilé, il peut s'avérer nécessaire de modifier localement la paroi du corps 1, afin de lui conférer une plus grande souplesse, lorsqu'il équipe une feuillure présentant en certains emplacements des courbures importantes.This body 1 is intended to cap by pinching a protruding part of an opening or an opening frame of a motor vehicle and, to lock it in position on this projecting part, in known manner, one or more lips 2 in EPDM or thermoplastic material, here having a hardness of about 65 SHORE A, protrude obliquely from the face of each of the branches of the body 1 towards the opposite branch and the base of this body. To reduce the weight of the profile, while maintaining sufficient rigidity, a rigid foam elastomer or plastomer, with a density of 0.3 to 0.8 g / cm 3 , is housed in a hollow portion 3 of the body 1, which marries the general form and with which it is coextruded. With such a profile, it may be necessary to modify locally the wall of the body 1, to give it greater flexibility when it equips a rabbet having in some locations significant curvatures.

Dans ce cas, comme représenté sur la figure la, en vue d'accroître la stabilité du profilé sur la feuillure en ces emplacements, on peut avantageusement prévoir localement au moins une fente 11 disposée obliquement dans au moins une paroi de la partie du corps 1 l'l'l'In this case, as shown in FIG. 1a, in order to increase the stability of the profile on the rabbet at these locations, it is advantageous to locally provide at least one slot 11 arranged obliquely in at least one wall of the part of the body 1 the the the

destinée à coiffer la feuillure et à partir de laquelle les lèvres 2 font saillie en direction de l'autre paroi. La fente 11 est emplie du même matériau de remplissage que la partie creuse du corps 1, ce matériau affleurant ainsi à l'extérieur du profilé au niveau de cette fente. En variante, comme représenté sur la figure Ib, on peut aussi prévoir localement en 12 une réduction importante de l'épaisseur d'au moins une paroi de la partie en U du corps 1 destinée à coiffer une feuillure ou une autre partie saillante.intended to cap the rabbet and from which the lips 2 protrude towards the other wall. The slot 11 is filled with the same filling material as the hollow part of the body 1, this material is flush with the outside of the profile at this slot. As a variant, as shown in FIG. 1b, it is also possible locally to provide a substantial reduction in the thickness of at least one wall of the U-shaped portion of the body 1 intended to cap a rabbet or other projecting part.

Dans le cas de la réalisation de la figure 2, on retrouve un corps l' a section en U dépourvu d'armature de renfort et constitué du mêmeIn the case of the embodiment of FIG. 2, there is a U-section body with no reinforcing reinforcement and consisting of the same

E. P. D. M. ou du même matériau thermoplastique que précédemment, dont les ailes comportent, sur leur face tournée vers l'aile opposée, des lèvres 2' dirigées vers l'aile opposée et vers la base du U.E. p. D. or the same thermoplastic material as before, whose wings comprise, on their side facing the opposite wing, lips 2 'directed towards the opposite wing and towards the base of the U.

Dans cette forme de réalisation, toutefois, le corps comprend deux parties creuses 3'a et 3'b, emplies d'une mousse, rigide, qui s'étendent chacune dans une branche du U du corps et dans une partie de la base de celui-ci, où elles sont séparées par une cloison 4'.In this embodiment, however, the body comprises two hollow portions 3'a and 3'b, filled with a rigid foam, which each extend into a branch of the U of the body and into a portion of the base of the body. this one, where they are separated by a partition 4 '.

On accroît ainsi la résistance de cette base, ce qui permet au profilé d'épouser fidèlement la forme des feuillures qu'il est destiné à équiper, sans déformation des ailes du corps , et sans qu'elles tendent à s'écarter l'une de l'autre, même lorsque ces feuillures sont fortement recourbées suivant des angles de 90° ou moins.This increases the strength of this base, which allows the profile to marry faithfully the shape of rabbets that it is intended to equip, without deformation of the wings of the body, and without they tend to deviate one of them. on the other, even when these rabbets are strongly curved at angles of 90 ° or less.

A cette forme de réalisation de l'invention s'appliquent bien entendu les adaptations locales du profilé qui ont été décrites ci-dessus en référence aux figures la et Ib, en vue d'accroître la stabilité du profilé sur des parties fortement recourbées de la feuillure qu'il est appelé à coiffer.In this embodiment of the invention naturally apply the local adaptations of the profile which have been described above with reference to Figures la and Ib, in order to increase the stability of the profile on strongly curved parts of the rabbet that he is called to style.

La forme de réalisation illustrée par la figure 1 est difficilement transposable à un profilé comportant des parties creuses dépourvues d'un matériau de remplissage, car un tel profilé ne présenterait pas une stabilité suffisante sur la feuillure qu'il équipe.The embodiment illustrated in Figure 1 is difficult to transpose to a section having hollow portions without a filler material, such a profile would not have sufficient stability on the rebate it equips.

En revanche, la structure de la figure 2 se prête mieux à la suppression d'un matériau de remplissage dans les parties creuses, qui ne contiennent alors que de l'air ou un autre gaz, ce qui accroît la légèreté du profilé sans nuire à ses propriétés mécaniques.In contrast, the structure of Figure 2 is best for the removal of a filler material in the hollow parts, which then contain only air or another gas, which increases the lightness of the profile without harming its mechanical properties.

Dans un tel cas, cependant, comme représenté sur la figure 3, où les organes déjà décrits sont désignés par les mêmes chiffres de référence affectés de l'indice ", il est préférable de prévoir des cloisons transversales 4", 5" ou 6", entre les différentes parties creuses 8", 9" et 10", afin d'accroître la stabilité du profilé.In such a case, however, as shown in FIG. 3, where the members already described are designated by the same figures of FIG. reference affected by the index ", it is preferable to provide transverse partitions 4", 5 "or 6", between the different hollow portions 8 ", 9" and 10 ", in order to increase the stability of the profile.

On notera que les profilés conformes à l'invention sont faciles à réaliser, moyennant un coût réduit, par la technique usuelle de la coextrusion. Note that the profiles according to the invention are easy to achieve, at a reduced cost, by the usual technique of coextrusion.
