Description

ÉLÉMENT D'ÉTANCHÉITÉ DESTINÉ NOTAMMENT À ÊTRE MONTÉ AUTOUR DES OUVERTURES DE PORTES DE VÉHICULES AUTOMOBILES SEALING ELEMENT, IN PARTICULAR FOR MOUNTING AROUND VEHICLE DOOR OPENINGS
La présente invention concerne un élément d'étanchéité destiné notamment à être monté autour des ouvertures de portes de véhicules automobiles et destinée à établir un contact avec une vitre coulissante ou fixe.The present invention relates to a sealing element intended in particular to be mounted around the door openings of motor vehicles and intended to establish contact with a sliding or fixed window.
De tels éléments sont destinés à des véhicules automobiles, et plus généralement tout engin muni de glaces coulissantes ou fixes dont l'étanchéité est assurée par des coulisses horizontales et verticales comportant des lèvres venant s'appliquer sur les faces opposées des glaces, tout en autorisant la cas échéant le déplacement selon deux directions opposées, généralement suivant un axe vertical et en limitant les vibrations.Such elements are intended for motor vehicles, and more generally any machine provided with sliding or fixed windows, the sealing of which is ensured by horizontal and vertical slides comprising lips coming to be applied on the opposite faces of the windows, while allowing if necessary displacement in two opposite directions, generally along a vertical axis and limiting vibrations.
La structure porteuse, généralement la porte ou la carrosserie du véhicule, présente une ouverture entourée par un logement pour recevoir un joint en caoutchouc, en matière plastique ou en un matériau élastique équivalent. Ce joint présente habituellement un canal de section sensiblement en U dans lequel vient se positionner la vitre et une partie dorsale propre à venir se loger dans le logement prévu à cet effet dans la porte ou la carrosserie du véhicule. Les joints sont généralement fabriqués par extrusion, technique qui permet de réaliser des éléments présentant des sections complexes. Cette technique ne permet toutefois que la fabrication d'éléments longitudinaux. De ce fait, les éléments d'étanchéité sont composés de pièces rectilignes raccordées par des éléments de jonction moulés. Ces éléments de jonction présentent des inconvénients sur le plan esthétique, car ils forment une discontinuité visible, ainsi que sur le plan de l'étanchéité, puisqu'ils créent une rupture des traitements d'amélioration du glissement, par flocage par exemple. Des éléments d'étanchéité selon l'état de la technique sont par exemple décrits dans le brevet français FR2696379 divulguant un joint d'étanchéité pour vitres mobiles formé par deux profils respectivement avant et arrière réunis par une garniture centrale. Ce joint est assemblé avant l'incorporation sur le véhicule. Les zones de raccordement constituent des points d'affaiblissement. Le joint peut de se fait se rompre au moment de la mise en place sur le véhicule. On a également proposé des joints à section constante permettant une fabrication par extrusion, dont la souplesse est suffisante pour permettre une mise en place sous la forme d'un cordon d'étanchéité venant entourer la partie supérieure de l'ouverture. Un tel joint nécessite toutefois des pièces complémentaires telles que des lécheurs pour les bords inférieurs de l'ouverture. L'assemblage de tels joints est de ce fait relativement complexe et présente les inconvénients précités.The supporting structure, generally the door or the body of the vehicle, has an opening surrounded by a housing for receiving a seal made of rubber, plastic or an equivalent elastic material. This seal usually has a substantially U-shaped section channel in which the window is positioned and a clean back part to be housed in the housing provided for this purpose in the door or the body of the vehicle. Joints are generally manufactured by extrusion, a technique which allows elements with complex sections to be produced. However, this technique only allows the production of longitudinal elements. Therefore, the sealing elements are composed of rectilinear parts connected by molded junction elements. These junction elements have drawbacks on the aesthetic level, because they form a visible discontinuity, as well as on the sealing level, since they create a break in the treatments for improving the slip, by flocking for example. Sealing elements according to the state of the art are for example described in French patent FR2696379 disclosing a seal for movable windows formed by two profiles respectively front and rear joined by a central trim. This seal is assembled before incorporation on the vehicle. The connection zones constitute weakening points. The seal may break due to installation on the vehicle. There have also been proposed constant section seals allowing manufacture by extrusion, the flexibility of which is sufficient to allow installation in the form of a sealing bead which surrounds the upper part of the opening. Such a seal, however, requires additional parts such as wipers for the lower edges of the opening. The assembly of such seals is therefore relatively complex and has the aforementioned drawbacks.
L'objet de la présente invention est de remédier aux inconvénients des éléments d'étanchéité selon l'état de la technique en proposant un élément d'étanchéité solide, de faible coût de fabrication et évitant toute discontinuité tant esthétique que mécanique.The object of the present invention is to remedy the drawbacks of sealing elements according to the state of the art by proposing a solid sealing element, of low manufacturing cost and avoiding any discontinuity both aesthetic and mechanical.
A cet effet, l'invention concerne un élément d'étanchéité comportant un joint en caoutchouc, en matière plastique ou en un matériau élastique équivalent, présentant un canal de section sensiblement en U dans lequel vient se positionner la vitre coulissante et une partie dorsale propre à venir se loger dans le logement prévu à cet effet dans la porte du véhicule, caractérisé en ce qu'il est composé de deux cadres moulés réunis sur deux côtés au moins par un joint surmoulé pour former un ensemble unique d"étanchéification de la surface vitrée. Les cadres moulés s ' étendent sur une partie au moins du pourtour de l'ouverture. Ils peuvent éventuellement être réalisés sous forme de plusieurs tronçons rigides adjacents et raccordés par le joint surmoulé pour former un ensemble deformable temporairement pour la mise en place dans le logement destiné à le recevoir.To this end, the invention relates to a sealing element comprising a rubber, plastic or equivalent elastic material seal, having a substantially U-shaped section channel in which the sliding window is positioned and a clean back part. to be housed in the housing provided for this purpose in the vehicle door, characterized in that it is composed of two molded frames joined on at least two sides by a molded joint to form a single assembly for sealing the surface The molded frames extend over at least part of the periphery of the opening and can optionally be produced in the form of several adjacent rigid sections which are connected by the overmolded joint to form a temporarily deformable assembly for placement in the housing intended to receive it.
Les cadres moulés sont préférentiellement réalisés en une matière recyclable de préférence une matière plastique, notamment une matière thermoplastique à haute résistance thermique et sont réunis par un joint surmoulé en un matériau de moindre dureté que celle du matériau constituant lesdits cadres. Ce mode de réalisation est particulièrement avantageux par rapport aux problèmes de recyclage des matériaux. Les matières thermoplastiques sont en effet beaucoup plus facilement recyclables que le caoutchouc ou EPDM. Les éléments d'étanchéité selonThe molded frames are preferably made of a recyclable material, preferably a plastic material, in particular a thermoplastic material with high thermal resistance and are joined by a molded joint in a material of less hardness than that of the material constituting said frames. This embodiment is particularly advantageous compared to the problems of recycling materials. Thermoplastics are much more easily recyclable than rubber or EPDM. Sealing elements according to
1 ' invention permettent une meilleure récupération des matériaux et donc un meilleur respect des normes en matière de protection de l'environnement.1 invention allow better recovery of materials and therefore better compliance with standards for environmental protection.
Selon un mode de réalisation préféré, les deux cadres présentent une section en "L" . Ce mode de réalisation permet une fabrication facile par moulage. Selon une variante, les deux cadres comportent en outre un montant transversal présentant une section en "T" .According to a preferred embodiment, the two frames have an "L" section. This embodiment allows easy manufacture by molding. Alternatively, the two frames further comprise a transverse upright having a "T" section.
Selon une autre variante avantageuse, les cadres présentent des protubérances latérales pour le clipsage dans le logement prévu sur la porte pour recevoir les éléments d'étanchéité.According to another advantageous variant, the frames have lateral protrusions for clipping into the housing provided on the door to receive the sealing elements.
Selon une autre variante avantageuse, les cadres sont coupés en un endroit par une incision.According to another advantageous variant, the frames are cut in one place by an incision.
Cette incision autorise une déformation temporaire du cadre au moment de 1 ' intégration en force dans la porte du véhicule.This incision authorizes a temporary deformation of the frame at the time of the force integration into the vehicle door.
Selon un mode de réalisation préféré, les deux cadres sont reliés sur deux côtés au moins par un joint en caoutchouc, en matière plastique ou en un matériau élastique équivalent, présentant un canal de section sensiblement enAccording to a preferred embodiment, the two frames are connected on at least two sides by a seal made of rubber, plastic or an equivalent elastic material, having a section channel substantially in
"U" dans lequel vient se positionner la vitre coulissante et une partie dorsale propre à venir se loger dans le logement prévu à cet effet dans la porte du véhicule. Le fond du canal présente, lorsque l'élément d'étanchéité est positionné dans le logement de la porte, un plissement de section transversale faisant saillie à l'intérieur du canal en "U" de manière à ce que le bord de la vitre coulissante vient s'appuyer sur la crête de ladite plissure."U" in which the sliding window is positioned and a clean back part to be housed in the housing provided for this purpose in the vehicle door. The bottom of the channel has, when the sealing element is positioned in the housing of the door, a fold of cross section projecting inside the U-shaped channel so that the edge of the sliding window comes to rest on the crest of said pleat.
Avantageusement, le plissement du fond (2) présente une forme en "Ω" . Selon une variante, les montants transversaux sont reliés par un joint définissant de chaque côté un canal en "U" .Advantageously, the folding of the bottom (2) has a shape in "Ω". According to a variant, the transverse uprights are connected by a joint defining on each side a "U" channel.

La figure 1 représente une vue schématique de la porte du véhicule. La porte (51) présente une découpe (52) délimitée par un logement (53) destiné à recevoir l'élément d'étanchéité. L'élément d'étanchéité est composé de deux cadres (54, 55) dont la forme et la dimension correspondent à celles du logement (53) . Ces cadres (54, 55) sont réalisés par moulage d'une matière thermoplastique. Ils présentent une entaille (56) qui permet de déformer temporairement l'élément d'étanchéité, pour la mise en place dans son logement.Figure 1 shows a schematic view of the vehicle door. The door (51) has a cutout (52) delimited by a housing (53) intended to receive the sealing element. The sealing element is composed of two frames (54, 55) whose shape and size correspond to those of the housing (53). These frames (54, 55) are made by molding a thermoplastic material. They have a notch (56) which makes it possible to temporarily deform the sealing element, for positioning in its housing.
La figure 2 représente une vue de l'élément d'étanchéité selon l'invention selon l'une des coupes transversales A-A', B-B' ou C-C . La section des cadres (54, 55) présente la forme générale d'un "L" . Ces deux cadres (54, 55) sont réunis par un joint en caoutchouc formé par surmoulage et qui définit un canal central (1) présentant une section en "U" , délimité par un fond (2) et par deux parois latérales (3, 4) . Les parois latérales (3, 4) sont surmontées par des lèvres (5, 6) pouvant s'appuyer sur les surfaces internes et externes de la glace coulissante. Le joint présente par ailleurs des prolongements latéraux (7, 8) sensiblement parallèles aux parois latérales (3, 4) et définissant entre ces dernières une nervure (9, 10) parallèle au canal (1) , dans lesquels viendront se positionner les flancs du logement de la porte destinés à recevoir le joint. Les plans médians (11, 12) forment avec le plan de symétrie (12) du joint un angle de l'ordre de 75 degrés, les deux plans (11, 12) convergent vers le centre du canal (1) . Les surfaces intérieures du canal en "U" peuvent être traitées de manière connue par flocage, par un revêtement ou par tout autre procédé facilitant le glissement des glaces. Avant que le joint ne soit positionné dans son logement, le fond (2) est plat dans l'exemple de réalisation décrit. La largeur du joint est supérieure à la largeur du logement destiné à la recevoir. De ce fait, lorsque le joint est positionné dans son logement, il est déformé latéralement comme indiqué par les flèches FI et F2, et le fond (2) se déforme comme représenté en hachures fines sur la figure 1, le centre du canal (2) se déformant vers l'intérieur du canal en "U" comme indiqué par la flèche F3. Le fond présente alors un plissement (14) . Ce plissement2 shows a view of the sealing element according to the invention according to one of the cross sections A-A ', BB' or CC. The frame section (54, 55) has the general shape of an "L". These two frames (54, 55) are joined by a rubber seal formed by overmolding and which defines a central channel (1) having a "U" section, delimited by a bottom (2) and by two side walls (3, 4). The side walls (3, 4) are surmounted by lips (5, 6) which can rest on the internal and external surfaces of the sliding glass. The seal also has lateral extensions (7, 8) substantially parallel to the side walls (3, 4) and defining between the latter a rib (9, 10) parallel to the channel (1), in which the sides of the door housing intended to receive the seal. The median planes (11, 12) form with the plane of symmetry (12) of the joint an angle of the order of 75 degrees, the two planes (11, 12) converge towards the center of the channel (1). The internal surfaces of the U-shaped channel can be treated in a known manner by flocking, by a coating or by any other process facilitating the sliding of the glass. Before the seal is positioned in its housing, the bottom (2) is flat in the embodiment described. The width of the joint is greater than the width of the housing intended to receive it. Therefore, when the seal is positioned in its housing, it is deformed laterally as indicated by the arrows FI and F2, and the bottom (2) is deformed as shown in fine hatching in Figure 1, the center of the channel (2 ) deforming towards the inside of the U-shaped channel as indicated by arrow F3. The bottom then has a crease (14). This puckering
(14) fait saillie vers l'intérieur du canal en "U" et présente une forme générale en "Ω" . La crête (15) viendra s'appuyer sur le bord de la vitre (16) comme représenté en figure 2. La porte présente un logement délimité latéralement par deux flancs (17, 18) sur lesquels viennent se positionner les rainures (9, 10) . La largeur de ce logement est inférieure à la largeur du joint au repos, ce qui provoque l'écrasement transversal et produit la déformation du fond (2) en forme de plissure en "Ω" dont la crête (15) vient s'appuyer contre le bord de la vitre (16) .(14) protrudes towards the inside of the channel in a "U" shape and has a general shape in "Ω". The crest (15) will come to rest on the edge of the glass (16) as shown in FIG. 2. The door has a housing delimited laterally by two sides (17, 18) on which the grooves (9, 10 are positioned) ). The width of this housing is less than the width of the joint at rest, which causes the transverse crushing and produces the deformation of the bottom (2) in the form of a pleat in "Ω" whose crest (15) comes to bear against the edge of the window (16).
Ce bord écrase légèrement la plissure (14) qui vient assurer l'étanchéité et le positionnement latéral de la glace (16) .This edge slightly crushes the pleat (14) which ensures the sealing and the lateral positioning of the glass (16).
Les deux cadres (54, 55) sont écartés lors du surmoulage, de telle sorte que les branches inférieures (27, 28) sont reliées par une membrane (25) réalisée par surmoulage, et présentant au repos préférentiellement un aspect légèrement bombé. Les bords latéraux inférieurs (50, 51) des piècesThe two frames (54, 55) are separated during overmolding, so that the lower legs (27, 28) are connected by a membrane (25) produced by overmolding, and preferably having a slightly curved appearance at rest. The lower lateral edges (50, 51) of the parts
(54, 55) sont de forme complémentaire de manière à ce que les deux pièces puissent se raccorder et former une embase monobloc lorsque l'élément d'étanchéité est en place.(54, 55) are of complementary shape so that the two parts can be connected and form a one-piece base when the sealing element is in place.
La figure 3 représente une vue en coupe de l'élément d'étanchéité lorsqu'il est mis en place dans son logement. Lorsque l'élément d'étanchéité est mis en place dans le logement de la porte prévu à cet effet, les deux pièces (54, 55) en "L" sont rapprochées, ce qui provoque une déformation de la membrane (25) comme représentée en figure 3. La membrane (25) formant le fond du canal (1) en "U" présente alors une plissure dont la section transversale est en forme de "Ω" . Les deux cadres (54, 55) présentent par ailleurs des protubérances (22, 23) permettant le clipsage dans des cavités prévues à cet effet dans le logement de la porte destiné à recevoir l'élément d'étanchéité.Figure 3 shows a sectional view of the sealing element when it is placed in its housing. When the sealing element is placed in the housing of the door provided for this purpose, the two parts (54, 55) in "L" are brought together, which causes a deformation of the membrane (25) as shown in figure 3. The membrane (25) forming the bottom of the channel (1) in "U" then has a fold whose cross section is in the shape of "Ω". The two frames (54, 55) also have protuberances (22, 23) for clipping into cavities provided for this purpose in the housing of the door intended to receive the sealing element.
Bien entendu, de telles protubérances de clipsage peuvent également être prévues directement sur les surfaces extérieures des parois latérales du canal en "U" ou sur les prolongements latéraux.Of course, such clipping protuberances can also be provided directly on the exterior surfaces of the side walls of the "U" channel or on the side extensions.
La figure 6 représente une vue de face d'une réalisation pour un véhicule de type "coupé" . Les cadres présentent une première ouverture (60) pour recevoir une glace coulissante et une deuxième ouverture (61) pour recevoir une glace de custode fixe. Les cadres présentent une partie périphérique (64) coupée par une fente (63) permettant une déformation au moment de son positionnement dans le logement destinée à le recevoir. Les cadres comportent en outre un montant transversal (65) séparant la partie vitrée mobile (60) de la partie vitrée fixe (61) . La partie périphérique du cadre présente une section en "L" comme précédemment décrit pour les éléments d'étanchéité destinés à recevoir uniquement une glace mobile. Les montants transversaux (64) des cadres présentent une section en "T" et sont surmoulés d'un côté par un joint permettant le coulissement d'une glace mobile, et de l'autre coté par un joint pour le maintien d'une glace de custode fixe.FIG. 6 represents a front view of an embodiment for a "coupe" type vehicle. The frames have a first opening (60) to receive a sliding window and a second opening (61) to receive a fixed quarter window. The frames have a peripheral part (64) cut by a slot (63) allowing a deformation at the time of its positioning in the housing intended to receive it. The frames also comprise a transverse upright (65) separating the movable glazed part (60) from the fixed glazed part (61). The peripheral part of the frame has an "L" section as previously described for the sealing elements intended to receive only movable glass. The transverse uprights (64) of the frames have a "T" section and are molded on one side by a seal allowing the sliding of a movable glass, and on the other side by a seal for holding a glass. fixed quarter panel.
Les figures 7 et 8 représentent des vues en coupe transversale selon le plan de coupe E-E' respectivement avant et après la mise en place dans le logement destiné à recevoir le joint d'étanchéité.Figures 7 and 8 show cross-sectional views along the cutting plane E-E 'respectively before and after installation in the housing intended to receive the seal.
L'élément d'étanchéité présente au niveau du montant transversal (64) les deux parties du cadre moulées en matière plastique (30, 31) présentant une section en "T", surmoulée d'un côté avec un joint conforme à ceux précédemment décrit, et de l'autre côté par un joint pour une vitre fixe. Ce joint est par exemple formé de deux lèvres (32, 33) et de parois latérales (34, 35) définissant un canal central (36) . Le fond présente deux demi-bourrelets (37, 38) saillant vers l'intérieur du canal (36) . Lorsque les deux parties latérales sont rapprochées, ces demi- bourrelets (37, 38) viennent se rencontrer pour former une zone d'appui du bord de la glace fixe. La barre transversale des pièces (30, 31) en "T" sert de montants de séparation de la glace coulissante et de la glace fixe. Bien entendu, ce type d'élément d'étanchéité pourrait également être employé pour la liaison de deux glaces coulissantes.The sealing element has at the transverse upright (64) the two parts of the molded plastic frame (30, 31) having a "T" section, overmolded on one side with a seal conforming to those previously described , and on the other side by a joint for a fixed window. This seal is for example formed by two lips (32, 33) and side walls (34, 35) defining a central channel (36). The bottom has two half-beads (37, 38) projecting towards the inside of the channel (36). When the two lateral parts are brought together, these half-beads (37, 38) come together to form a support zone for the edge of the fixed lens. The transverse bar of the "T" parts (30, 31) serves as separation posts for the sliding glass and the fixed glass. Of course, this type of sealing element could also be used for the connection of two sliding windows.
L'invention est décrite dans ce qui précède à titre d'exemple non limitatif. L'homme du métier sera à même de réaliser différentes variantes sans pour autant sortir du cadre de 1 ' invention. The invention is described in the foregoing by way of nonlimiting example. Those skilled in the art will be able to produce different variants without departing from the scope of the invention.
