  • the invention concerns also the actual electrical connection.
  • the invention also relates to glazing provided with such a connection.

  • glazings can be used in the field of transport vehicles, for example automobile, rail, aeronautical or in the field of building.
  • the electrical connection supported by a substrate, forming part of the glazing consists of a foil or a conductive layer, for example based on silver paste deposited in particular by screen printing.
  • This electrical connection is connected, at the edge of glazing, to a cable located outside the glazing, connected to a non-glazed equipment.
  • a seal usually protects the connection of external stresses and especially moisture.
  • the substrate forming part of the glazing is at least partly transparent, it may be a glass sheet, it may be made of organic or inorganic glass optionally coated with one or more mineral and / or organic layers. It may be enamelled layer (s), metal layers based on metal oxides, especially zinc oxides, ITO, SnO 2 , SiO 2 , Ag deposited (s), for example, by pyrolysis or under vacuum of an organic coating, for example based on an organosilane and / or an optionally fluorinated organosiloxane (s).
  • the cable leading the electrical signals is usually located outside the glazing within the bodywork bay, for example.
  • the electrical connection between the conductive strip and the cable is generally placed so that the length of the cable is reduced.
  • the position of the connection on the glazing is imposed by the location of the cable in the bodywork bay.
  • the imposed position of the connection may correspond to a curvature of the glazing, so it may be difficult to make the electrical connection. Moreover, the imposed position of the connection does not always correspond to that of the elements requiring this electrical connection. It is then necessary to connect these two positions by a conductive strip, based on silver paste, for example. This conductive strip is unattractive. In addition, the material used is generally expensive.
  • the electrical power that can convey a conductive strip depends in particular on its width. For a given width, the electric power can not exceed a certain value. This limitation can be troublesome when the width imparted for the conductive strip does not correspond to the desired power for the glazing.
  • the present invention obviates these disadvantages.
  • the invention relates to a glazing unit that can be powered with any electric power for a width as small as 2 mm.

It is preferably at the periphery of the substrate and, preferably, at the periphery edge. It is advantageously located in the part of the substrate intended to be hidden. Preferably, the electrical connection is close to the accessories supplied with electrical signals. It is, for example, located for a heated rear window, on the side of the glazing to be mounted in a post, preferably in the center of this side. As a result, the length of the conductive strip, based on silver paste for example, is thus limited. Its presence can be advantageously suppressed.
  • the cable of the invention can be fixed on the surface or on the edge of the substrate. It can be located within an area protected from external stresses, for example within the so-called sealing zone, delimited by a seal. It can also be located outside this sealing area. This is particularly the case when it is a glazing opening, that is to say a glazing that opens regardless of the opening of a door. It is then subjected to external stresses, such as air, water, detergent solutions and shocks. It can also cross, at its output out of the glazing, the boundary between two zones, the so-called sealing zone and the so-called non-sealing zone.

This attachment can be by welding, using an adhesive tape or fasteners. It is advantageously fixed by gluing, especially when exposed to the view. It is preferably glued with the aid of a ribbon comprising, on each of its faces, an adhesive layer. Any risk of overflow, due in particular to the creep of an adhesive, is thus eliminated. Moreover, the bonding operation is particularly easy to implement.
  • the adhesive tape is preferably a foam having on each of its faces an adhesive layer.
  • This is, for example, a foam of the acrylic type or polyurethane type.
  • a primer is applied to both the glazing and the cable.
  • the primer applied on the cable may be chlorinated polypropylene type comprising ester groups.
  • the primer applied to the glass may be a mixture of isopropanol, mercaptosilanes and diaminosilanes.

  • the value of the resistance is satisfactory when, in particular, the cable is subjected to external stresses.
  • the shape of the cable may be semi-cylindrical or cylindrical. It is advantageously flat in order to limit its size in height.
  • the shape of the cable may be a function of the shape of the conductive filaments: they may form a flat braid or at least one wire.
  • the electrical connection between the cable and the accessories supplied with electrical signals is provided by an electrical contact between the end of the conductive portion of the cable and a conductive portion electrically connected to the elements.
  • This contact can be provided by a weld, advantageously by ultrasound, the insertion of two lugs or any other appropriate means.
  • the conductive filaments of the cable are in direct electrical contact with at least one accessory supplied with electrical signals.

  • the profiled piece may have the shape of a parallelepiped, a semi-cylinder or, advantageously, a trapezium: for the same base surface, ensuring its fixing, its size is reduced. Any other form may also be considered; advantageously, the conductive element, in particular the conductive filaments of the cable, are supported by a base in order to obtain at the same time a precise positioning of the cable and to be free from any possible gap in the geometry of the glazing.
  • the material constituting the coating of the electrical connection, a conductive strip and / or the conductive filaments of the cable may be identical to that constituting the sheath of the cable. It can also be another material. This is, for example, this polyvinyl chloride, polyurethane, polysulfide or polyamide, preferably reinforced.

  • An adhesive is then advantageously injected into the cavity formed by the profiled piece, to ensure its sealing. It also ensures its adhesion.
  • a primer can be applied to the glazing prior to gluing. This is, for example, a glue of the hot melt type, preferably of the polyamide type. The coating may optionally serve as a mold, being subsequently removed.

Description

Un exemple d'un vitrage selon le préambule de la revendication 1 est decrit dans EP-A-0 153 806 .An example of a glazing according to the preamble of claim 1 is described in EP-A-0 153 806 .

L'invention concerne un équipement destiné à relier électriquement au moins un accessoire supporté par un vitrage à un équipement hors vitrage, par exemple à une source d'alimentation électrique, à des capteurs, à une radio, etc... L'invention concerne également la liaison électrique proprement dite. L'invention concerne également le vitrage muni d'une telle liaison.The invention relates to an equipment for electrically connecting at least one accessory supported by a glazing unit to non-glazed equipment, for example to a power supply source, to sensors, to a radio, etc. The invention concerns also the actual electrical connection. The invention also relates to glazing provided with such a connection.

Il existe différents types de vitrages nécessitant une connexion électrique. Il s'agit, par exemple, de vitrages chauffants, dégivrants, à propriétés optiques électrocommandées ou de vitrages équipés de capteurs, d'une antenne, d'un feu de signalisation, etc...There are different types of glazing that require an electrical connection. This is, for example, heating windows, de-icing, electrically controlled optical properties or glazing equipped with sensors, an antenna, a traffic light, etc ...

Ces vitrages peuvent être utilisés dans le domaine des véhicules de transport, par exemple automobile, ferroviaire, aéronautique ou dans le domaine du bâtiment.These glazings can be used in the field of transport vehicles, for example automobile, rail, aeronautical or in the field of building.

Usuellement, la liaison électrique, supportée par un substrat, entrant dans la constitution du vitrage est constituée d'un clinquant ou d'une couche conductrice, par exemple à base de pâte d'argent déposée notamment par sérigraphie. Cette liaison électrique est connectée, en bord de vitrage, à un câble situé en dehors du vitrage, relié à un équipement hors vitrage. Un joint d'étanchéité protège usuellement la liaison des sollicitations extérieures et notamment de l'humidité.Usually, the electrical connection, supported by a substrate, forming part of the glazing consists of a foil or a conductive layer, for example based on silver paste deposited in particular by screen printing. This electrical connection is connected, at the edge of glazing, to a cable located outside the glazing, connected to a non-glazed equipment. A seal usually protects the connection of external stresses and especially moisture.

Le substrat entrant dans la constitution du vitrage est au moins transparent en partie, ce peut être une feuille de verre, il peut être en verre organique ou minéral éventuellement revêtu d'une ou plusieurs couches minérales et/ou organiques. Il peut s'agir de couche(s) émaillée(s), de couches métalliques à base d'oxydes métalliques, notamment oxydes de zinc, ITO, SnO2, SiO2, Ag déposée(s), par exemple, par pyrolyse ou sous vide d'un revêtement organique, par exemple à base d'un organosilane et/ou d'un organosiloxane éventuellement fluoré(s).The substrate forming part of the glazing is at least partly transparent, it may be a glass sheet, it may be made of organic or inorganic glass optionally coated with one or more mineral and / or organic layers. It may be enamelled layer (s), metal layers based on metal oxides, especially zinc oxides, ITO, SnO 2 , SiO 2 , Ag deposited (s), for example, by pyrolysis or under vacuum of an organic coating, for example based on an organosilane and / or an optionally fluorinated organosiloxane (s).

Pour des raisons d'encombrement, le câble conduisant les signaux électriques est usuellement situé en dehors du vitrage au sein de la baie de carrosserie, par exemple. Par ailleurs, la connexion électrique entre la bande conductrice et le câble est généralement placée de telle sorte que la longueur du câble soit réduite. Ainsi pour un véhicule donné, par exemple, la position de la connexion sur le vitrage est imposée par l'emplacement du câble dans la baie de carrosserie.For reasons of space, the cable leading the electrical signals is usually located outside the glazing within the bodywork bay, for example. Furthermore, the electrical connection between the conductive strip and the cable is generally placed so that the length of the cable is reduced. Thus for a given vehicle, for example, the position of the connection on the glazing is imposed by the location of the cable in the bodywork bay.

La position imposée de la connexion peut correspondre à une courbure du vitrage, il peut alors être malaisé d'effectuer la connexion électrique. Par ailleurs, la position imposée de la connexion ne correspond pas toujours à celle des éléments nécessitant cette liaison électrique. Il est alors nécessaire de relier ces deux positions par une bande conductrice, à base de pâte d'argent, par exemple. Cette bande conductrice est peu esthétique. En outre, le matériau utilisé est généralement onéreux.The imposed position of the connection may correspond to a curvature of the glazing, so it may be difficult to make the electrical connection. Moreover, the imposed position of the connection does not always correspond to that of the elements requiring this electrical connection. It is then necessary to connect these two positions by a conductive strip, based on silver paste, for example. This conductive strip is unattractive. In addition, the material used is generally expensive.

Par ailleurs, la puissance électrique qui peut acheminer une bande conductrice dépend notamment de sa largeur. Pour une largeur donnée, la puissance électrique ne peut excéder une certaine valeur. Cette limitation peut être gênante lorsque la largeur impartie pour la bande conductrice ne correspond pas à la puissance désirée pour le vitrage.Moreover, the electrical power that can convey a conductive strip depends in particular on its width. For a given width, the electric power can not exceed a certain value. This limitation can be troublesome when the width imparted for the conductive strip does not correspond to the desired power for the glazing.

La présente invention obvie à ces inconvénients.The present invention obviates these disadvantages.

L'invention concerne un vitrage pouvant être alimenté avec une puissance électrique quelconque pour une largeur aussi petite que 2 mm.The invention relates to a glazing unit that can be powered with any electric power for a width as small as 2 mm.

L'invention concerne, par ailleurs, un vitrage prêt à la monte.The invention also relates to glazing ready for mounting.

La présente invention concerne un vitrage selon la revendication 1.The present invention relates to glazing according to claim 1.

On appelle câble, des filaments conducteurs susceptibles de transmettre des signaux électriques, enrobés d'au moins une gaine, par exemple une gaine standard en polychlorure de polyvinyle.Conducting filaments capable of transmitting electrical signals coated with at least one sheath, for example a standard polyvinyl chloride sheath, are called cables.

La position de la connexion électrique du câble aux accessoires alimentés en signaux électriques peut être, selon l'invention, à tout endroit du substrat, quelle que soit la structure du véhicule. Elle est, de préférence, en périphérie du substrat et, de façon préférée, en bord de périphérie. Elle est avantageusement située dans la partie du substrat destinée à être cachée. De façon préférée, la connexion électrique est à proximité des accessoires alimentés en signaux électriques. Elle est, par exemple, située, pour une lunette arrière chauffante, sur le côté du vitrage destiné à être monté dans un montant, avantageusement au centre de ce côté. De ce fait, la longueur de la bande conductrice, à base de pâte d'argent par exemple, est ainsi limitée. Sa présence peut être avantageusement supprimée.The position of the electrical connection of the cable to the accessories supplied with electrical signals may be, according to the invention, at any point on the substrate, whatever the structure of the vehicle. It is preferably at the periphery of the substrate and, preferably, at the periphery edge. It is advantageously located in the part of the substrate intended to be hidden. Preferably, the electrical connection is close to the accessories supplied with electrical signals. It is, for example, located for a heated rear window, on the side of the glazing to be mounted in a post, preferably in the center of this side. As a result, the length of the conductive strip, based on silver paste for example, is thus limited. Its presence can be advantageously suppressed.

Le câble de l'invention peut être fixé en surface ou sur le chant du substrat. Il peut être situé au sein d'une zone protégée des sollicitations extérieures, par exemple au sein de la zone dite d'étanchéité, délimitée par un joint d'étanchéité. Il peut être également situé hors de cette zone d'étanchéité. C'est notamment le cas lorsqu'il s'agit d'un vitrage ouvrant, c'est-à-dire un vitrage qui s'ouvre indépendamment de l'ouverture d'une porte. Il est alors soumis aux sollicitations extérieures, telles que air, eau, solutions détergentes ainsi qu'aux chocs. Il peut également traverser, à sa sortie hors du vitrage, la limite entre deux zones, la zone dite d'étanchéité et la zone dite hors étanchéité.The cable of the invention can be fixed on the surface or on the edge of the substrate. It can be located within an area protected from external stresses, for example within the so-called sealing zone, delimited by a seal. It can also be located outside this sealing area. This is particularly the case when it is a glazing opening, that is to say a glazing that opens regardless of the opening of a door. It is then subjected to external stresses, such as air, water, detergent solutions and shocks. It can also cross, at its output out of the glazing, the boundary between two zones, the so-called sealing zone and the so-called non-sealing zone.

Le vitrage de l'invention peut comporter plusieurs accessoires alimentés en signaux électriques. Avantageusement, ces accessoires électriques sont connectées au même câble. Un même câble reliant électriquement plusieurs accessoires, le nombre de sorties de câbles est ainsi limité. Le vitrage de l'invention comporte, avantageusement, une unique sortie de câble.The glazing of the invention may comprise several accessories supplied with electrical signals. Advantageously, these electrical accessories are connected to the same cable. The same cable electrically connecting several accessories, the number of cable outlets is thus limited. The glazing unit of the invention advantageously comprises a single cable outlet.

Le câble de l'invention est fixé au substrat indirectement. Il est logé dans un enrobage lui-même fixé sur le substrat. Cette fixation peut être par soudure, à l'aide d'un ruban adhésif ou d'attaches. Il est avantageusement fixé par collage, notamment lorsqu'il est exposé à la vue. Il est, de préférence, collé à l'aide d'un ruban comportant, sur chacune de ses faces, une couche adhésive. Tout risque de débordement, dû notamment au fluage d'une colle, est ainsi éliminé. Par ailleurs, l'opération de collage est particulièrement facile à mettre en oeuvre.The cable of the invention is attached to the substrate indirectly. It is housed in a coating itself attached to the substrate. This attachment can be by welding, using an adhesive tape or fasteners. It is advantageously fixed by gluing, especially when exposed to the view. It is preferably glued with the aid of a ribbon comprising, on each of its faces, an adhesive layer. Any risk of overflow, due in particular to the creep of an adhesive, is thus eliminated. Moreover, the bonding operation is particularly easy to implement.

Afin de mieux épouser les variations de planéité et/ou de courbure éventuels du vitrage, le ruban adhésif est, de préférence, une mousse comportant sur chacune de ses faces une couche adhésive. Il s'agit, par exemple, d'une mousse du type acrylique ou du type polyuréthane.In order to better match any variations in flatness and / or curvature of the glazing, the adhesive tape is preferably a foam having on each of its faces an adhesive layer. This is, for example, a foam of the acrylic type or polyurethane type.

Avantageusement, après un nettoyage de la surface à encoller, un primaire est appliqué à la fois sur le vitrage et sur le câble. Le primaire appliqué sur le câble peut être du type polypropylène chloré comportant des groupements esters.Advantageously, after cleaning the surface to be bonded, a primer is applied to both the glazing and the cable. The primer applied on the cable may be chlorinated polypropylene type comprising ester groups.

Le primaire appliqué sur le verre peut être un mélange d'isopropanol, de mercaptosilanes et de diaminosilanes. Une deuxième couche de primaire à base d'isocyanate peut éventuellement être appliquée. Il peut s'agir également d'une résine à base d'un mélange vinyl-polyuréthane.The primer applied to the glass may be a mixture of isopropanol, mercaptosilanes and diaminosilanes. A second layer of isocyanate-based primer may optionally be applied. It may also be a resin based on a vinyl-polyurethane mixture.

L'adhésion du câble via son enrobage, sur le vitrage peut présenter une résistance supérieure ou égale à 5 N/cm mesuré selon le test dit de pelage à 90°. La valeur de la résistance est satisfaisante lorsque, notamment, le câble est soumis aux sollicitations extérieures.The adhesion of the cable via its coating on the glazing may have a resistance greater than or equal to 5 N / cm measured according to the so-called peel test at 90 °. The value of the resistance is satisfactory when, in particular, the cable is subjected to external stresses.

La forme du câble peut être semi-cylindrique ou cylindrique. Elle est avantageusement plate afin d'en limiter l'encombrement en hauteur. La forme du câble peut être fonction de la forme des filaments conducteurs : ils peuvent former une tresse plate ou au moins un fil.The shape of the cable may be semi-cylindrical or cylindrical. It is advantageously flat in order to limit its size in height. The shape of the cable may be a function of the shape of the conductive filaments: they may form a flat braid or at least one wire.

La connexion électrique entre le câble et les accessoires alimentés en signaux électrique est assurée par un contact électrique entre l'extrémité de la partie conductrice du câble et une partie conductrice reliée électriquement aux éléments. Ce contact peut être assuré par une soudure, avantageusement par ultrasons, l'enfichage de deux cosses ou tout autre moyen approprié. Selon un mode de réalisation de l'invention, les filaments conducteurs du câble sont en contact électrique direct avec au moins un accessoire alimenté en signaux électriques.The electrical connection between the cable and the accessories supplied with electrical signals is provided by an electrical contact between the end of the conductive portion of the cable and a conductive portion electrically connected to the elements. This contact can be provided by a weld, advantageously by ultrasound, the insertion of two lugs or any other appropriate means. According to one embodiment of the invention, the conductive filaments of the cable are in direct electrical contact with at least one accessory supplied with electrical signals.

Selon une variante avantageuse, au moins un élément conducteur du vitrage est recouvert par un enrobage. Cet enrobage peut permettre de cacher l'élément conducteur à la vue. Il protège en outre, en quelque sorte, l'élément conducteur de tout choc éventuel. Il s'agit, par exemple, d'un élément conducteur situé sur une des faces du substrat ou sur le chant du substrat, par exemple une bande conductrice, les filaments conducteurs du câble ou une connexion électrique. Il peut également assurer avantageusement l'étanchéité de l'élément conducteur lorsqu'il est situé hors de la zone d'étanchéité.According to an advantageous variant, at least one conductive element of the glazing is covered by a coating. This coating can hide the conductive element to the view. It also protects, in a way, the conductive element from any possible shock. This is, for example, a conductive element located on one of the faces of the substrate or on the edge of the substrate, for example a conductive strip, the conductive filaments of the cable or an electrical connection. It can also advantageously ensure the sealing of the conductive element when it is located outside the sealing zone.

Le matériau constituant l'enrobage est choisi parmi les matériaux suivants : chlorure de polyvinyle, polyuréthane, EPDM (Ethylène Propylène Diène Monomère), polysulfure, polyamide ou un mélange de polyuréthane et de polyamide.The material constituting the coating is chosen from the following materials: polyvinyl chloride, polyurethane, EPDM (Ethylene Propylene Diene Monomer), polysulfide, polyamide or a mixture of polyurethane and polyamide.

De manière préférée, au moins une partie des filaments conducteurs du câble est noyée dans un enrobage. Cet enrobage, appelé gaine dans la suite de la description, peut être extrudée afin d'en limiter l'encombrement sur le vitrage. Elle peut également être moulée ou, avantageusement, surmoulée.Preferably, at least a portion of the conductive filaments of the cable is embedded in a coating. This coating, called sheath in the following description, can be extruded in order to limit its size on the glazing. It can also be molded or, advantageously, overmoulded.

Le matériau constituant la gaine du câble doit être un isolant électrique et présenter une résistance mécanique suffisante pour ne pas être endommagé par tout heurt éventuel. Par ailleurs, il doit être étanche à l'eau et à une atmosphère saline, notamment lorsqu'il est exposé à l'atmosphère environnante. Il s'agit, par exemple, de chlorure de polyvinyle, de polyuréthane, d'un mélange de polyuréthane et de polyamide ou d'un caoutchouc, par exemple du type EPDM (Ethylène Propylène Diène Monomère). Il s'agit, par exemple, d'un polyuréthane. Afin d'améliorer sa fixation sur le vitrage, notamment lorsque la gaine est avantageusement collée, cette dernière présente selon l'invention une base plane. Afin d'obtenir une fixation satisfaisante, la largeur de sa base est avantageusement supérieure ou égale à 2 mm. Les dimensions de la base de la gaine sont évidemment un compromis entre, d'une part l'obtention d'une bonne adhésion et, d'autre part un encombrement réduit. La hauteur de la gaine peut être aussi petite que 5 mm, voire 2 mm. Deux gaines peuvent être superposées l'une à l'autre. La gaine intérieure est, par exemple, une gaine standard, généralement commercialisée avec la partie conductrice du câble.The material constituting the sheath of the cable must be an electrical insulator and have sufficient mechanical strength to not be damaged by any possible collision. In addition, it must be waterproof to a saline atmosphere, especially when exposed to the surrounding atmosphere. This is, for example, polyvinyl chloride, polyurethane, a mixture of polyurethane and polyamide or a rubber, for example of the EPDM type (Ethylene Propylene Diene Monomer). This is, for example, a polyurethane. In order to improve its attachment to the glazing, especially when the sheath is advantageously bonded, the sheath according to the invention has a flat base. In order to obtain a satisfactory fixation, the width of its base is advantageously greater than or equal to 2 mm. The dimensions of the base of the sheath are obviously a compromise between, on the one hand, obtaining a good adhesion and, on the other hand, a reduced bulk. The height of the sheath can be as small as 5 mm or even 2 mm. Two sheaths can be superimposed on one another. The inner sheath is, for example, a standard sheath, generally marketed with the conductive portion of the cable.

Le câble selon l'invention peut présenter des changements de direction. Lorsque la gaine est extrudée, on utilise de préférence, selon l'invention, un matériau du type mousse afin d'obtenir une bonne adhésion au niveau de la courbure, notamment lorsque le rayon de courbure est court ou qu'il existe un angle vif. Les inventeurs ont ainsi montré qu'avec ce type de matériau, la surface de collage était la même au niveau des changements de direction qu'au niveau des segments droits. Une autre solution, selon les inventeurs, est d'utiliser un câble dont la gaine est coextrudée de manière à pouvoir, au niveau des changements de direction, mettre à nu la gaine intérieure de plus faible volume. L'utilisation d'un enrobage à deux gaines superposées permet, en outre, de fixer le câble dans des zones où l'encombrement du câble demande à être réduit, en déshabillant partiellement le câble tout en conservant ses caractéristiques isolantes.The cable according to the invention may have changes of direction. When the sheath is extruded, according to the invention, a foam-type material is preferably used in order to obtain good adhesion at the level of the curvature, especially when the radius of curvature is short or when there is a sharp angle. . The inventors have thus shown that with this type of material, the bonding surface was the same at the level of changes of direction as at the level of straight segments. Another solution, according to the inventors, is to use a cable whose sheath is coextruded so as to be able, at the level of changes of direction, to expose the inner sheath of smaller volume. The use of a coating with two superposed sheaths also makes it possible to fix the cable in areas where the bulk of the cable needs to be reduced, by partially stripping the cable while retaining its insulating characteristics.

Le profil de la gaine de l'invention peut comporter, de préférence, au moins une lèvre venant s'appliquer sur le vitrage. L'aspect esthétique en est d'autant amélioré.The profile of the sheath of the invention may comprise, preferably, at least one lip that is applied to the glazing. The aesthetic aspect is all improved.

Un enrobage peut également être une pièce profilée recouvrant un élément conducteur, notamment une connexion électrique et/ou les filaments conducteurs du câble. Il chapeaute en quelque sorte l'élément conducteur. Cette dernière est, par exemple, située sur une partie plane ou courbe du vitrage. Ses dimensions sont fonction des dimensions de l'élément conducteur. Pour une connexion électrique, elles peuvent être calculées de manière à recouvrir un éventuel jeu entre la partie conductrice du câble et sa gaine. Elle peut également recouvrir au moins une partie de la bande conductrice, la masquant ainsi à la vue et/ou assurant son étanchéité. A titre indicatif, sa largeur est, par exemple, comprise entre 20 et 25 mm, sa longueur entre 30 et 40 mm et sa hauteur entre 3 et 5 mm. La pièce profilée peut avoir la forme d'un parallélépipède, d'un semi-cylindre ou, avantageusement, d'un trapèze : pour la même surface de base, assurant sa fixation, son encombrement est réduit. Toute autre forme peut également être envisagée ; avantageusement, l'élément conducteur, notamment les filaments conducteurs du câble, sont supportés par une embase afin d'obtenir à la fois un positionnement précis du câble et de s'affranchir de tout écart éventuel de géométrie du vitrage.A coating may also be a profiled piece covering a conductive element, in particular an electrical connection and / or the conductive filaments of the cable. It somehow closes the conductive element. The latter is, for example, located on a flat or curved portion of the glazing. Its dimensions are a function of the dimensions of the conductive element. For an electrical connection, they can be calculated so as to cover a possible clearance between the conductive part of the cable and its sheath. It can also cover at least a portion of the conductive strip, thus masking it to the view and / or ensuring its sealing. As an indication, its width is, for example, between 20 and 25 mm, its length between 30 and 40 mm and its height between 3 and 5 mm. The profiled piece may have the shape of a parallelepiped, a semi-cylinder or, advantageously, a trapezium: for the same base surface, ensuring its fixing, its size is reduced. Any other form may also be considered; advantageously, the conductive element, in particular the conductive filaments of the cable, are supported by a base in order to obtain at the same time a precise positioning of the cable and to be free from any possible gap in the geometry of the glazing.

Le matériau constituant l'enrobage de la connexion électrique, d'une bande conductrice et/ou des filaments conducteurs du câble peut être identique à celui constituant la gaine du câble. Il peut s'agir également d'un autre matériau. Il s'agit, par exemple, ce chlorure de polyvinyle, de polyuréthane, de polysulfure ou de polyamide, de préférence renforcé. L'enrobage de la connexion et/ou d'une bande conductrice et du câble ne peuvent former qu'une pièce, notamment si cet enrobage est surmoulé. Ils peuvent également former plusieurs pièces distinctes, de préférence lorsqu'il s'agit de plusieurs pièces usinées ou moulées, collées sur le vitrage.The material constituting the coating of the electrical connection, a conductive strip and / or the conductive filaments of the cable may be identical to that constituting the sheath of the cable. It can also be another material. This is, for example, this polyvinyl chloride, polyurethane, polysulfide or polyamide, preferably reinforced. The coating of the connection and / or a conductive strip and the cable can form only one part, especially if this coating is overmolded. They can also form several separate parts, preferably when it comes to several machined or molded parts glued to the glazing.

Selon une variante avantageuse, l'enrobage de l'élément conducteur assure son étanchéité. Il peut, par exemple, être situé hors de la zone d'étanchéité, délimitée par un joint d'étanchéité et être ainsi soumis aux sollicitations extérieures.According to an advantageous variant, the coating of the conductive element ensures its sealing. It may, for example, be located outside the sealing zone, delimited by a seal and thus be subjected to external stresses.

Une colle est alors avantageusement injectée à l'intérieur de la cavité formée par la pièce profilée, afin d'assurer son étanchéité. Elle assure également avantageusement son adhésion. Un primaire peut être appliqué sur le vitrage préalablement à l'encollage. Il s'agit, par exemple, d'une colle du type thermofusible, de préférence du type polyamide. L'enrobage peut, éventuellement, servir de moule, étant enlevé par la suite.An adhesive is then advantageously injected into the cavity formed by the profiled piece, to ensure its sealing. It also ensures its adhesion. A primer can be applied to the glazing prior to gluing. This is, for example, a glue of the hot melt type, preferably of the polyamide type. The coating may optionally serve as a mold, being subsequently removed.

L'invention concerne également un moyen pour éviter toute infiltration d'humidité dans la zone d'étanchéité lorsque, notamment, le câble traverse, à sa sortie hors du vitrage, la limite entre la zone dite hors étanchéité et la zone d'étanchéité. C'est notamment le cas lorsque le câble est en dehors de la zone délimitée par un joint d'étanchéité, la source d'alimentation en signaux électriques étant, quant à elle, dans une zone protégée des sollicitations extérieures par un joint d'étanchéité. Cette configuration se trouve, par exemple, lorsque le vitrage et ouvrant, c'est-à-dire qu'il est susceptible de s'ouvrir indépendamment de l'ouverture d'une porte. Le câble peut alors conduire à une pénétration d'humidité dans la zone dite d'étanchéité. Or, les équipements dans cette zone ne sont pas nécessairement revêtus d'une protection étanche.The invention also relates to a means for preventing moisture penetration into the sealing zone when, in particular, the cable passes, at its exit out of the glazing, the boundary between the so-called out-of-seal zone and the sealing zone. This is particularly the case when the cable is outside the zone delimited by a seal, the power source of electrical signals being, for its part, in a zone protected from external stresses by a seal . This configuration is, for example, when the glazing and opening, that is to say it is likely to open regardless of the opening of a door. The cable can then lead to a penetration of moisture into the so-called sealing zone. However, the equipment in this zone is not necessarily covered with waterproof protection.

Selon une variante avantageuse, la partie du câble traversant à sa sortie hors du vitrage la limite entre la zone d'étanchéité et la zone hors étanchéité est noyée dans une pièce rapportée comportant un moyen de fixation destiné à la fixer sur le substrat.According to an advantageous variant, the portion of the cable passing through its exit out of the glazing the boundary between the sealing zone and the off-tight zone is embedded in an insert having a fixing means for fixing it on the substrate.

Le moyen de fixation peut être une partie ou une patte solidaire de la pièce rapportée, cette partie ou cette patte étant destinée à être fixée sur le substrat notamment par collage. Elles peuvent également être fixées à l'aide d'un ruban adhésif comportant éventuellement sur chacune de ses faces une couche adhésive, une attache tel qu'un cavalier ou tout autre moyen adéquat. Selon une variante avantageuse, le moyen de fixation est un ancrage mécanique entre la pièce rapportée et une pièce auxiliaire, elle-même fixée sur le substrat. La pièce peut ainsi ne pas être en contact avec le vitrage, évitant ainsi toute surépaisseur. Selon une variante particulièrement avantageuse, cette pièce auxiliaire constitue l'enrobage d'un élément conducteur, notamment d'une partie du câble située hors de la zone d'étanchéité. Elle peut alors cacher la liaison électrique à la vue. Elle peut également éventuellement assurer, ou du moins améliorer, son étanchéité. D'autre part, sa présence permet de s'affranchir de tout écart éventuel relatif à la dimension de la liaison électrique. La pièce rapportée de l'invention peut également être fixée au substrat à l'aide d'un ancrage mécanique et, d'une partie ou d'une patte, fixée au vitrage.The fixing means may be a part or a tab integral with the insert, this part or this tab being intended to be fixed on the substrate in particular by gluing. They can also be fixed with an adhesive tape optionally comprising on each of its faces an adhesive layer, a fastener such as a rider or any other suitable means. According to an advantageous variant, the fixing means is a mechanical anchoring between the insert and an auxiliary part, itself fixed on the substrate. The piece can thus not be in contact with the glazing, thus avoiding any extra thickness. According to a particularly advantageous variant, this auxiliary part constitutes the coating of a conductive element, in particular of a portion of the cable located outside the sealing zone. It can then hide the electrical connection to the view. It can also possibly ensure, or at least improve, its tightness. On the other hand, its presence makes it possible to overcome any possible deviation in the dimension of the electrical connection. The insert of the invention may also be attached to the substrate with a mechanical anchor and a part or lug attached to the glazing.

L'ancrage mécanique est assuré, de préférence, par un renflement sur l'une des pièces, la pièce rapportée ou la pièce auxiliaire, l'autre pièce comportant la partie complémentaire.The mechanical anchoring is provided, preferably, by a bulge on one of the parts, the insert or the auxiliary part, the other part having the complementary part.

La pièce rapportée de l'invention peut comporter d'autres fonctions que celles inhérentes à l'étanchéité du câble noyé en son sein. Elle peut, par exemple, comporter des moyens de fixation pour un rétroviseur, des moyens pour une alimentation en air ou en eau ou toute autre fonction dans la mesure où cette fonction est nécessaire à l'endroit du vitrage où sort la liaison électrique hors du vitrage. La pièce rapportée de l'invention comporte, avantageusement, une lèvre destinée à assurer la continuité d'une lèvre solidaire, par ailleurs, d'un joint de montage facilitant le montage du vitrage dans une baie.The insert of the invention may include other functions than those inherent in the sealing of the cable embedded therein. It may, for example, comprise fixing means for a rear-view mirror, means for an air or water supply or any other function insofar as this function is necessary at the location of the glazing where the electrical connection comes out of the window. glazing. The insert of the invention advantageously comprises a lip intended to ensure the continuity of a lip integral, moreover, a mounting gasket facilitating the mounting of the glazing in a bay.

La pièce rapportée peut être préfabriquée, rapportée et fixée sur le substrat entrant dans la constitution du vitrage. Elle est, par exemple, moulée autour d'une partie d'une liaison électrique, rapportée et fixée sur le substrat. Elle peut également être moulée directement sur le substrat muni de ladite liaison électrique.The insert can be prefabricated, attached and fixed on the substrate forming part of the glazing. It is, for example, molded around a portion of an electrical connection, attached and fixed on the substrate. It can also be molded directly onto the substrate provided with said electrical connection.

La technique de moulage permet, en particulier, d'obtenir des dimensions relativement petites tout en étant précises, ce qui permet de limiter l'encombrement de la pièce rapportée sur le vitrage. Les dimensions de la pièce rapportée sont fonction de l'utilisation envisagée. La hauteur de la pièce dépend, notamment, de la nature de la liaison surmoulée. Elle peut être aussi petite que 2 mm. Sa largeur dépend également de la largeur de la liaison et, éventuellement, du nombre de fils présents. Elle est, par exemple, comprise entre 4 et 100 mm. Sa longueur est, par exemple, comprise entre 4 et 100 mm.In particular, the molding technique makes it possible to obtain relatively small dimensions while being precise, which makes it possible to limit the bulk of the insert on the glazing. The dimensions of the insert are dependent on the intended use. The height of the part depends, in particular, on the nature of the overmolded connection. It can be as small as 2 mm. Its width also depends on the width of the link and possibly the number of wires present. It is, for example, between 4 and 100 mm. Its length is, for example, between 4 and 100 mm.

La figure 1 représente deux côtés d'un vitrage selon l'art antérieur.The figure 1 represents two sides of a glazing according to the prior art.

Le vitrage 1 comporte sur cette figure deux connexions électriques 2 et 3. Il s'agit, sur cette figure, d'un vitrage monolithique comportant un réseau de fils fins de résistance électrique chauffants 4. Chaque fil chauffant 4 est relié électriquement à deux bandes collectrices 5 et 6. Elles sont, par exemple, constituées de pâte d'argent déposée par sérigraphie. Leur largeur est fonction de la puissance électrique du vitrage. Les connexions électriques 2 ou 3 sont, en général, constituées d'une bande métallique 7 ou 8 soudée aux extrémités des bandes collectrices 5 et 6 respectivement. Les connexions ainsi que les bandes collectrices sont situées dans la zone d'étanchéité délimitée par le joint d'étanchéité représenté en 9.The glazing 1 comprises in this figure two electrical connections 2 and 3. It is, in this figure, a monolithic glazing comprising a network of thin electric heating resistance wires 4. Each heating wire 4 is electrically connected to two strips collectors 5 and 6. They are, for example, made of silver paste deposited by screen printing. Their width is a function of the electrical power of the glazing. The electrical connections 2 or 3 are, in general, made of a metal strip 7 or 8 welded to the ends of the collector strips 5 and 6 respectively. The connections as well as the collector strips are located in the sealing zone delimited by the seal shown at 9.

L'élément 2 est représenté en position non connectée, alors que l'élément 3 est représenté en position connectée.Element 2 is shown in the unconnected position, while element 3 is shown in the connected position.

L'extrémité de la partie conductrice d'un câble 10, logé dans la baie de carrosserie, est par exemple enfichée à la bande métallique 8.The end of the conductive part of a cable 10, housed in the bodywork bay, is for example connected to the metal strip 8.

Cette figure illustre la surface relativement importante de la bande collectrice afin de relier chaque fil chauffant 4 à la connexion électrique 2 ou 3.This figure illustrates the relatively large surface area of the manifold for connecting each heating wire 4 to the electrical connection 2 or 3.

La figure 2 est une vue de deux côtés possibles d'un vitrage selon l'invention. Il s'agit du même type de vitrage que celui illustré figure 1. Les connexions électriques 11 et 12 selon l'invention, sont situées à proximité des fils chauffants 4 pour la même position du câblage 10 de la baie de carrosserie vis-à-vis du vitrage. Cette disposition permet de réduire la longueur des bandes collectrices 5 et 6. Avantageusement, leur largeur décroît également, comme illustré sur la figure, réduisant ainsi la quantité de pâte d'argent utilisée tout en améliorant l'esthétique du vitrage. La connexion 11 est représentée enrobée alors que la connexion 12 est représentée non enrobée d'après la position du joint d'étanchéité 9 et 15, représentés en pointillé sur la figure.The figure 2 is a view of two possible sides of a glazing according to the invention. This is the same type of glazing as illustrated figure 1 . The electrical connections 11 and 12 according to the invention are located near the heating wires 4 for the same position of the wiring 10 of the bodywork bay vis-à-vis the glazing. This arrangement reduces the length of the collector strips 5 and 6. Advantageously, their width also decreases, as illustrated in the figure, thereby reducing the amount of silver paste used while improving the aesthetics of the glazing. The connection 11 is shown coated while the connection 12 is shown uncoated according to the position of the seal 9 and 15, shown in dashed lines in the figure.

La connexion électrique est constituée, par exemple, d'une bande métallique 13 susceptible de venir s'enficher à l'extrémité des filaments conducteurs 14 du câble. Il peut s'agir également d'une connexion par soudure ou de tout autre moyen. Avantageusement, il s'agit d'une soudure par ultrasons. Les filaments conducteurs 14 du câble sont sous forme de fil(s) ou de tresse(s) plate(s). La bande métallique 13 et les filaments conducteurs 14 peuvent être laissés nus comme illustré sur la figure de par la position du joint d'étanchéité 9.The electrical connection is constituted, for example, of a metal strip 13 may come to plug at the end of the conductive filaments 14 of the cable. It can also be a connection by welding or any other means. Advantageously, it is an ultrasonic weld. The conductive filaments 14 of the cable are in the form of wire (s) or braid (s) flat (s). The metal strip 13 and the conductive filaments 14 can be left bare as illustrated in the figure by the position of the seal 9.

De par la position du joint d'étanchéité 15, la connexion 11 ainsi que les filaments conducteurs 16 du câble sont enrobées. Le câble fixé au substrat est ici constitué de filaments conducteurs 16 et d'une gaine 17. Cette dernière épouse la forme des filaments conducteurs 16 afin, à la fois, d'assurer une étanchéité, de réduire l'encombrement et d'éviter toute salissure s'infiltrant entre la partie conductrice 16 et la gaine. La gaine 17 comporte, de préférence, une base plate afin de faciliter sa fixation. Elle est, de préférence, semi-cylindrique ou plate selon la forme de la partie conductrice du câble. Afin d'assurer une étanchéité satisfaisante en dehors de la zone d'étanchéité, comme représenté sur la figure, il s'agit, de préférence, d'une gaine en polyuréthane.By the position of the seal 15, the connection 11 and the conductive filaments 16 of the cable are coated. The cable attached to the substrate here consists of conducting filaments 16 and a sheath 17. The latter conforms to the shape of the conductive filaments 16 in order both to ensure a seal, to reduce the bulk and to avoid any dirt infiltrating between the conductive portion 16 and the sheath. The sheath 17 preferably comprises a flat base in order to facilitate its fixing. It is preferably semi-cylindrical or flat in the form of the conductive portion of the cable. In order to ensure a satisfactory seal outside the sealing zone, as shown in the figure, it is preferably a polyurethane sheath.

L'enrobage 18 de la connexion 11 est ici représenté de forme trapézoïdale afin d'augmenter sa surface en contact avec le vitrage. Cet enrobage permet, par ailleurs, de camoufler, tout en assurant l'étanchéité, un éventuel jeu existant entre les filaments conducteurs 16 du câble et la gaine 17.The coating 18 of the connection 11 is here represented trapezoidal in order to increase its surface in contact with the glazing. This coating also makes it possible to camouflage, while sealing, any gap existing between the conductive filaments 16 of the cable and the sheath 17.

Par ailleurs, la bande collectrice 6 est ici représentée dans la zone d'étanchéité délimitée par le joint 15. Elle peut, selon l'invention, se situer en dehors de cette zone d'étanchéité. Elle est alors recouverte du même type d'enrobage que l'enrobage 18 de la connexion 11. Il peut s'agir éventuellement de la même pièce.Moreover, the collecting strip 6 is here represented in the sealing zone defined by the seal 15. It can, according to the invention, be located outside this sealing zone. It is then covered with the same type of coating as the coating 18 of the connection 11. It may be possibly the same piece.

La figure 3 représente une variante avantageuse de l'invention. Seule une partie du vitrage est représentée. Les deux bandes collectrices 5 et 6 sont connectées au même câble 19. Le câble 19 peut également relier électriquement un ou plusieurs autres accessoires nécessitant une alimentation électrique. A titre illustratif, il relie un feu-stop 20 à une source d'alimentation électrique. Il peut également relier une antenne, des dispositifs optiques... Le vitrage ne comporte alors qu'une sortie de câble, référencée en 21. La sortie de câble 21 peut, bien entendu, se situer en tout endroit sur le vitrage. Elle est ici représentée en partie haute du vitrage. Une pièce rapportée 22 peut, éventuellement, assurer la jonction entre les différentes parties conductrices provenant de part et d'autre du vitrage.The figure 3 represents an advantageous variant of the invention. Only a part of the glazing is represented. The two collector strips 5 and 6 are connected to the same cable 19. The cable 19 can also electrically connect one or more other accessories requiring a power supply. As an illustration, it connects a stop lamp 20 to a power source. It can also connect an antenna, optical devices ... The glazing then has only one cable outlet, referenced 21. The cable outlet 21 can, of course, be located anywhere on the glazing. It is here represented in the upper part of the glazing. An insert 22 may, optionally, ensure the junction between the different conductive parts from both sides of the glazing.

La figure 4 est une vue schématique d'un bas de pare-brise, hors de la zone d'étanchéité, représentée par des hachures et délimité par le joint d'étanchéité 23. Des fils fins de résistance électrique chauffants 24 permettent, par exemple, de dégivrer la zone du pare-brise à proximité des essuie-glaces. Deux connexions 25 relient électriquement ces fils 24 à une source d'alimentation électrique via un câble 26 fixé sur le substrat.The figure 4 is a schematic view of a windshield bottom, out of the sealing zone, represented by hatching and delimited by the gasket 23. Thin electric heating resistance wires 24 allow, for example, to defrost the area of the windshield near the wipers. Two connections 25 electrically connect these wires 24 to a power source via a cable 26 fixed to the substrate.

La figure 5 représente une variante avantageuse selon laquelle la surface d'une bande collectrice est réduite ou supprimée. Les filaments conducteurs du câble forment une tresse métallique en contact électrique direct avec au moins un accessoire alimenté en signaux électriques, par exemple les fils chauffants 4. Un enrobage 28 des connexions électriques peut éventuellement être prévu. Il peut recouvrir toutes ou une partie des connexions, comme représenté sur la figure, selon la position du joint d'étanchéité non représenté.The figure 5 represents an advantageous variant in which the surface of a collecting strip is reduced or eliminated. The conductive filaments of the cable form a metal braid in direct electrical contact with at least one accessory supplied with electrical signals, for example the heating wires 4. An encapsulation 28 of the electrical connections may optionally be provided. It can cover all or part of the connections, as shown in the figure, according to the position of the seal not shown.

Afin d'éviter une connexion électrique pour chaque fil chauffant 4 à la tresse 27, une bande collectrice 29 peut, par exemple, relier électriquement tous ces fils chauffants. Le câble de l'invention est alors constitué de filaments conducteurs 30 recouvrant partiellement ou totalement la bande 29. Une seule connexion entre la bande 29 et les filaments conducteurs 30 est alors nécessaire. Les filaments conducteurs 30 peuvent éventuellement être recouverte d'un enrobage non représenté.In order to avoid an electrical connection for each heating wire 4 to the braid 27, a collecting band 29 may, for example, electrically connect all these heating wires. The cable of the invention is then made of conductive filaments 30 partially or completely covering the strip 29. A single connection between the strip 29 and the conductive filaments 30 is then necessary. The conductive filaments 30 may optionally be covered with a coating not shown.

La figure 6 comporte quatre schémas représentant le câble fixé au vitrage selon l'invention. Sur le schéma 6a, le câble vient longer le chant du vitrage en 31. Il peut être maintenu par un ruban adhésif 32, par des attaches ou tout autre moyen. Il peut être avantageusement noyé dans le joint d'étanchéité et, de préférence, surmoulé conjointement. Un moyen de fixation maintient avantageusement le câble au niveau de sa courbure. Il s'agit, par exemple, d'un cavalier comme illustré schématiquement en 33. Ce moyen permet, en outre, d'améliorer l'esthétique du vitrage et l'étanchéité du câble. Sur le schéma 6b, le câble décrit un rayon de courbure sur la partie périphérique du vitrage. Les rayons de courbure ici illustrés sont suffisamment importants pour que l'adhésion du câble sur le vitrage soit satisfaisante au niveau du rayon de courbure. Les rayons de courbure peuvent également être plus petits ou encore le câble peut décrire des angles vifs. La gaine du câble est alors avantageusement moulée ou surmoulée selon les directions voulues. Elle peut être également extrudée. Dans ce cas, le matériau utilisé est, de préférence, une mousse.The figure 6 comprises four diagrams representing the cable attached to the glazing according to the invention. In Figure 6a, the cable is along the edge of the glazing 31. It can be maintained by an adhesive tape 32, by fasteners or any other means. It can be advantageously embedded in the seal and, preferably, overmolded together. A fastening means advantageously maintains the cable at its curvature. This is, for example, a jumper as illustrated diagrammatically in 33. This means also makes it possible to improve the aesthetics of the glazing and the tightness of the cable. In Figure 6b, the cable describes a radius of curvature on the peripheral portion of the glazing. The radii of curvature illustrated here are sufficiently large that the adhesion of the cable to the glazing is satisfactory at the radius of curvature. The radii of curvature may also be smaller or the cable may describe sharp angles. The cable sheath is then advantageously molded or overmolded in the desired directions. It can also be extruded. In this case, the material used is preferably a foam.

Une autre solution est illustrée dans les schémas 6c et 6d selon laquelle le câble décrit un angle vif ou un petit rayon de courbure, bien que le matériau utilisé pour son gainage ne soit pas une mousse. Le câble est constitué, outre de filaments conducteurs non représentés, de deux gaines 34 et 35 superposées l'une à l'autre. La gaine 34 peut être une gaine standard, cylindrique, en PVC. La gaine 35 est mise à nu au niveau du rayon de courbure et fait apparaître la gaine 34. Le câble peut alors courir sur le vitrage, comme illustré sur le schéma 6c ou le long du chant du vitrage, comme illustré sur le schéma 6d. Elle est avantageusement collée sur la surface du substrat, selon le schéma 6c et maintenue par un ruban adhésif ou une attache 32 selon le schéma 6d. La gaine 35 peut ne pas être présente lorsque le câble s'étend le long du vitrage, comme illustré sur le schéma 6d. L'encombrement du câble, notamment er hauteur, est ainsi réduit. Il est évident que lorsque la gaine 35 est mise à nu, la gaine 34 doit présenter les propriétés adéquates, notamment une étanchéité suffisante, notamment lorsque le câble est situé hors zone d'étanchéité.Another solution is illustrated in diagrams 6c and 6d according to which the cable describes a sharp angle or a small radius of curvature, although the material used for its cladding is not a foam. The cable consists, in addition to unrepresented conductive filaments, of two sheaths 34 and 35 superimposed on one another. The sheath 34 may be a standard, cylindrical, PVC sheath. The sheath 35 is exposed at the radius of curvature and exposes the sheath 34. The cable can then run on the glazing, as shown in Figure 6c or along the edge of the glazing, as shown in Figure 6d. It is advantageously bonded to the surface of the substrate, according to the diagram 6c and held by an adhesive tape or a fastener 32 according to the diagram 6d. The sheath 35 may not be present when the cable extends along the glazing, as shown in Figure 6d. The size of the cable, especially height, is reduced. It is obvious that when the sheath 35 is exposed, the sheath 34 must have the appropriate properties, including a sufficient seal, especially when the cable is located outside the sealing zone.

La figure 7 représente une coupe schématique d'une gaine 36 fixée sur le vitrage. Elle comporte, de préférence, des lèvres 37 permettant, à la fois d'améliorer sa fixation sur le vitrage et de camoufler le collage de la gaine. Deux lèvres peuvent être prévues de part et d'autre du corps de la gaine, comme illustré. Il est également possible de prévoir une seule lèvre. Cette gaine 36 peut enrober les filaments conducteurs 38 du câble. Ces filaments conducteurs sont eux-mêmes enrobés d'une seconde gaine non représentée.The figure 7 represents a schematic section of a sheath 36 attached to the glazing. It preferably comprises lips 37 making it possible at the same time to improve its fixing on the glazing and to camouflage the gluing of the sheath. Two lips may be provided on both sides of the body of the sheath, as illustrated. It is also possible to provide a single lip. This sheath 36 can coat the conductive filaments 38 of the cable. These conductive filaments are themselves coated with a second sheath, not shown.

Ces filaments conducteurs 38 peuvent former plusieurs fils, comme illustré sur le schéma 7a. Chaque fil est constitué d'une multitude de filaments conducteurs. Ils peuvent également ne former qu'un fil. Les filaments conducteurs peuvent être plats, comme illustré sur le schéma 7b. Sur le schéma 7b, la gaine comporte un évidement 39 susceptible d'être rempli de colle. L'étanchéité des filaments conducteurs du câble en est d'autant améliorée. Cette colle peut, éventuellement, déborder dans les cavités 40 formées par les lèvres 37.These conductive filaments 38 can form several wires, as shown in FIG. 7a. Each wire consists of a multitude of conductive filaments. They can also form only one thread. The conductive filaments may be flat as shown in Figure 7b. In Figure 7b, the sheath has a recess 39 that can be filled with glue. The sealing of the conductive filaments of the cable is all the better. This glue may, possibly, overflow into the cavities 40 formed by the lips 37.

La figure 8 représente une sortie de câble sur le vitrage. Il s'agit d'un cavalier 41 dont la forme permet de chevaucher chacune des faces du vitrage. Il comporte un canal 42 dans lequel est insérée une partie du câble selon l'invention. Le câble est ainsi solidement maintenu à la position voulue en sortie de vitrage. Les deux ailes 43 et 44 du cavalier sont ici représentées de longueur inégale. Il va de soi qu'elles peuvent être de longueur identique ou que l'aile 43 peut être plus petite que l'aile 44. Les dimensions de la cavité 45 formée par ces deux ailes sont fonction des dimensions du vitrage. Elles peuvent être telles qu'elles assurent un maintien mécanique du cavalier sur le vitrage. De la colle peut éventuellement être appliquée afin d'améliorer ce maintien. Le matériau constituant ce moyen de fixation est, de préférence, rigide.The figure 8 represents a cable outlet on the glazing. It is a jumper 41 whose shape allows to overlap each face of the glazing. It comprises a channel 42 in which is inserted a portion of the cable according to the invention. The cable is thus firmly held in the desired position at the glazing outlet. The two wings 43 and 44 of the rider are here represented of unequal length. It goes without saying that they may be of identical length or that the wing 43 may be smaller than the wing 44. The dimensions of the cavity 45 formed by these two wings are a function of the dimensions of the glazing. They can be such as to ensure a mechanical support of the rider on the glazing. Glue may optionally be applied to improve this maintenance. The material constituting this fixing means is preferably rigid.

La figure 9 représente une autre variante de sortie de câble selon l'invention. Il s'agit d'un élément de connexion comportant une cosse femelle dans laquelle peut s'enficher l'extrémité 46 des filaments conducteurs du câble 47 de l'invention. Un enrobage 48 permet, de par sa forme, à la fois de maintenir le câble en position et d'améliorer l'étanchéité de cette connexion électrique. Un réservoir à colle 49 est prévu afin d'assurer l'étanchéité de la connexion. Le câble 50 est le câble qui est destiné à courir dans la baie de carrosserie.The figure 9 represents another variant of the cable outlet according to the invention. It is a connection element comprising a female lug in which can be plugged the end 46 of the conductive filaments of the cable 47 of the invention. A coating 48 allows, by its form, both to maintain the cable in position and improve the sealing of this electrical connection. An adhesive reservoir 49 is provided to seal the connection. The cable 50 is the cable that is intended to run in the bodywork bay.

La figure 10 représente une coupe de l'enrobage de la connexion. Une collerette 51 permet d'assurer la jonction avec un câble 52 et la connexion. Le câble 52 est constitué de filaments conducteurs 53 et de deux gaines 54 et 55. Une partie de la gaine 54 est recouverte par l'enrobage 56. Tout jeu éventuel entre la partie conductrice 53 et la gaine 54 est ainsi recouvert par l'enrobage 56. La partie conductrice 53 est connectée électriquement à une bande métallique 57 reliée électriquement aux accessoires alimentés en signaux électriques. Une fois la connexion avec les deux parties conductrices 53 et 56 assurée, l'enrobage 55 est maintenu en position par tout moyen. De la colle est injectée par le trou d'injection 58 assurant l'étanchéité de la connexion et, le cas échéant, l'adhésion de l'enrobage 56 sur le vitrage. L'enrobage peut avoir une forme semi-cylindrique, parallélépipédique ou trapézoïdale. Sa base est adaptée au profil du vitrage. Avantageusement, elle se déforme légèrement sous l'effet de l'injection de la colle, à haute température, s'adaptant ainsi parfaitement au profil du vitrage, notamment lorsqu'il est courbe. La largeur de sa base est, par exemple, comprise entre 20 et 25 mm et sa longueur est comprise entre 30 et 40 mm. Ces dimensions sont évidemment un compromis entre une bonne surface de collage et un encombrement réduit. Afin de bien délimiter son encombrement, cet enrobage est avantageusement moulé et collé sur le vitrage. Il peut également être surmoulé, éventuellement conjointement à d'autres éléments fonctionnels et/ou à au moins un joint d'étanchéité.The figure 10 represents a section of the coating of the connection. A flange 51 makes it possible to join a cable 52 and the connection. The cable 52 consists of conductive filaments 53 and two sheaths 54 and 55. Part of the sheath 54 is covered by the coating 56. Any play between the conductive portion 53 and the sheath 54 is thus covered by the coating. 56. The conductive portion 53 is electrically connected to a metal strip 57 electrically connected to the accessories supplied with electrical signals. Once the connection with the two conductive parts 53 and 56 is ensured, the coating 55 is held in position by any means. Glue is injected through the injection hole 58 ensuring the sealing of the connection and, where appropriate, the adhesion of the coating 56 to the glazing. The coating may have a semi-cylindrical, parallelepipedic or trapezoidal shape. Its base is adapted to the profile of the glazing. Advantageously, it deforms slightly under the effect of the injection of the glue, at high temperature, thus adapting perfectly to the profile of the glazing, especially when it is curved. The width of its base is, for example, between 20 and 25 mm and its length is between 30 and 40 mm. These dimensions are obviously a compromise between a good bonding surface and a small footprint. In order to clearly define its bulk, this coating is advantageously molded and glued on the glazing. It can also be overmoulded, possibly in conjunction with other functional elements and / or at least one seal.

La figure 11 représente une coupe longitudinale d'un vitrage selon l'invention. Le verre 59 est recouvert, sur au moins une partie de sa périphérie, d'un émail 60. Cet émail cache à la vue la partie conductrice 61, généralement de couleur blanche. Sur cette partie conductrice 61, est fixée une cosse métallique 62 afin d'assurer une connexion électrique. L'enrobage 63 selon l'invention permet de camoufler à la fois la partie conductrice 61 et la cosse 62.The figure 11 represents a longitudinal section of a glazing unit according to the invention. The glass 59 is covered on at least a portion of its periphery with an enamel 60. This glaze hides the conductive portion 61, which is generally white in color. On this conductive part 61, is fixed a metal lug 62 to provide an electrical connection. The coating 63 according to the invention makes it possible to conceal both the conductive portion 61 and the lug 62.

Un tel enrobage, posé et fixé sur la surface d'un vitrage, peut également assurer l'étanchéité tout en camouflant tout élément conducteur, par exemple une bande conductrice. Il présente l'avantage d'améliorer l'esthétique du vitrage tout en assurant une parfaite étanchéité, notamment lorsque de la colle est injectée au sein de sa cavité. Les éléments conducteurs ainsi enrobés peuvent être placés, par exemple hors de la zone d'étanchéité.Such a coating, placed and fixed on the surface of a glazing, can also ensure tightness while camouflaging any conductive element, for example a conductive strip. It has the advantage of improving the aesthetics of the glazing while ensuring a perfect seal, especially when glue is injected into its cavity. The conductive elements thus coated can be placed, for example out of the sealing zone.

La figure 12 représente différents types de pièces profilées recouvrant les filaments conducteurs 64 du câble. La pièce profilée 65 vient se fixer sur une embase 66 supportant les filaments conducteurs 64. Cette embase peut comporter des ergots 67 destinés à coopérer avec les ergots 68 de la pièce 65. L'embase est ici représentée collée à l'aide d'une couche adhésive 95.The figure 12 represents different types of profiled parts covering the conductive filaments 64 of the cable. The profiled piece 65 is fixed on a base 66 supporting the conductive filaments 64. This base may comprise pins 67 intended to cooperate with the lugs 68 of the part 65. The base is here shown glued with the aid of a adhesive layer 95.

La figure 13 représente un vitrage dont le câble traverse, à sa sortie du vitrage, la limite entre une zone d'étanchéité et une zone hors étanchéité.The figure 13 represents a glazing whose cable crosses, at the exit of the glazing, the boundary between a sealing zone and a non-sealing zone.

Sur cette figure, les câbles 69 et 70 sont connectés respectivement à deux bandes collectrices 5, 6 constituées, par exemple, de pâte à base d'argent déposée par sérigraphie. Chaque bande est connectée à des fils fins de résistance électrique 4 constituant un réseau chauffant.In this figure, the cables 69 and 70 are respectively connected to two collector strips 5, 6 consisting, for example, of silver-based paste deposited by screen printing. Each strip is connected to thin electrical resistance wires 4 constituting a heating network.

Les câbles 71 et 72 sont, quant à eux, connectés à un feu de signalisation 20, par exemple un feu-stop. L'enrobage 65, du type pièce profilée, recouvre avantageusement les câbles situés en dehors de la zone d'étanchéité délimitée par le joint 73. Sur cette figure, le réseau chauffant et les bandes collectrices 5 et 6 sont situés dans la zone d'étanchéité référencée A.The cables 71 and 72 are, for their part, connected to a signaling light 20, for example a stop lamp. The coating 65, of the profiled part type, advantageously covers the cables located outside the sealing zone delimited by the seal 73. In this figure, the heating network and the collector strips 5 and 6 are located in the zone of FIG. seal referenced A.

Les câbles, quant à eux, sont situés en dehors de la zone d'étanchéité, dans la zone dite hors étanchéité, référencée B, par exemple à l'extérieur du véhicule. La pièce 74 assure le passage des câbles de l'extérieur du véhicule, c'est-à-dire de la zone hors étanchéité référencée B à la zone d'étanchéité référencée C, ici à l'intérieur d'un soufflet 75 en communication avec l'intérieur de la baie de carrosserie, zone protégée des sollicitations extérieures et, notamment, de l'humidité.The cables, for their part, are located outside the sealing zone, in the so-called out-of-seal zone, referenced B, for example outside the vehicle. The piece 74 ensures the passage of the cables from the outside of the vehicle, that is to say from the out-of-seal zone referenced B to the sealing zone referenced C, here inside a bellows 75 in communication with the interior of the bodyshell, a zone protected from external stresses and, in particular, moisture.

Les références A, B et C désignent respectivement l'intérieur du véhicule, par exemple l'habitacle, l'extérieur du véhicule et l'espace caché intérieur à la carrosserie, dans lequel circulent tous les câbles. Le joint 73 délimite sur cette figure les zones A et B, alors que les zones B et C sont délimitées par la limite 76 de la baie de carrosserie.The references A, B and C respectively designate the inside of the vehicle, for example the passenger compartment, the outside of the vehicle and the concealed space inside the body, in which all the cables circulate. The seal 73 delimits in this figure the zones A and B, while the zones B and C are delimited by the limit 76 of the bodywork bay.

Le passage de l'intérieur à l'extérieur du véhicule, c'est-à-dire de la zone A à la zone B, est effectué, de préférence, grâce à la présence d'un enduit du type organique décrit, par exemple, dans la demande de brevet française non publiée FR 93/09595 , déposé sur une couche conductrice, par exemple une partie 77, 78 des bandes collectrices 5 et 6 respectivement.The passage from the inside to the outside of the vehicle, that is to say from zone A to zone B, is preferably carried out by virtue of the presence of a coating of the organic type described, for example in the unpublished French patent application FR 93/09595 deposited on a conductive layer, for example a portion 77, 78 of the collector strips 5 and 6 respectively.

L'étanchéité du passage de liaison électrique de la zone B à la zone C est assurée par la présence de la pièce 74 selon l'invention. Un soufflet 75 peut également être prévu afin de guider le ou les câble(s) dans la zone C à l'endroit désiré, en général vers une source d'alimentation en signaux électriques. Sur cette figure, la pièce 74 est fixée au substrat par un ancrage mécanique entre la pièce 74 et l'enrobage 65.The sealing of the electrical connection passage from zone B to zone C is ensured by the presence of the piece 74 according to the invention. A bellows 75 may also be provided to guide the cable (s) in the area C to the desired location, generally to a power source of electrical signals. In this figure, the piece 74 is fixed to the substrate by mechanical anchoring between the piece 74 and the coating 65.

La figure 14 représente une coupe selon la ligne I-I de la pièce rapportée 74 décrite dans la figure 13. Les liaisons électriques sont ici représentées sous forme de quatre câbles 69, 70, 71 et 72. Ces quatre câbles sont constitués d'un fil conducteur 79, lui-même constitué de filaments conducteurs, non représentés, chaque fil 79 étant revêtu d'une gaine 80. Il s'agit, par exemple, d'une gaine standard commercialisée avec le fil conducteur. Bien entendu, plusieurs fils isolés peuvent être revêtus d'une même gaine 80. Une partie de ces câbles 69, 70, 71 et 72 est noyée dans une pièce rapportée 74. Cette pièce 74 est en un matériau thermoplastique ou thermodurcissable présentant une étanchéité à l'eau, voire à une atmosphère saline, satisfaisante. Il peut, éventuellement, présenter une isolation électrique ainsi qu'une résistance mécanique suffisante pour ne pas être endommagé par tout heurt éventuel. Le matériau est un élastomère thermoplastique ou thermodurcissable choisi, par exemple, dans le groupe suivant : chlorure de polyvinyle, polyuréthane, mélange de polyuréthane et de polyamide, caoutchouc, notamment du type EPDM (Ethylène Propylène Diène Monomère). Cette pièce est, par exemple, surmoulée autour d'une partie des câbles 69, 70, 71 et 72. La présence d'humidité entre les câbles et le matériau constituant la pièce 74 est ainsi évitée.The figure 14 represents a section along the line II of the insert 74 described in FIG. figure 13 . The electrical connections are here represented in the form of four cables 69, 70, 71 and 72. These four cables consist of a conductor wire 79, itself made of conductive filaments, not shown, each wire 79 being coated with a sheath 80. This is, for example, a standard sheath marketed with the thread. Of course, several insulated wires may be coated with the same sheath 80. A portion of these cables 69, 70, 71 and 72 is embedded in an insert 74. This part 74 is made of a thermoplastic or thermosetting material with a watertight seal. water, or even a saline atmosphere, satisfactory. It may, possibly, have electrical insulation and sufficient mechanical strength to not be damaged by any collision. The material is a thermoplastic or thermosetting elastomer chosen, for example, from the following group: polyvinyl chloride, polyurethane, polyurethane and polyamide mixture, rubber, especially of the EPDM (Ethylene Propylene Diene Monomer) type. This piece is, for example, overmolded around a portion of the cables 69, 70, 71 and 72. The presence of moisture between the cables and the material constituting the part 74 is thus avoided.

Sur cette figure, la pièce comporte un renflement, ici représenté sous forme d'une collerette 81 afin d'assurer sa fixation sur un vitrage par un ancrage mécanique. L'ancrage mécanique peut également être assuré par un évidement, une saillie, un décrochement, une butée, etc... et leur partie complémentaire respectivement.In this figure, the piece comprises a bulge, here shown in the form of a collar 81 to ensure its attachment to a glazing by a mechanical anchor. The mechanical anchoring may also be provided by a recess, a projection, a recess, a stop, etc ... and their complementary part respectively.

Les câbles sont ici représentés revêtus d'une gaine. Il peut s'agir d'une gaine standard, par exemple en polychlorure de vinyle, ou d'une gaine 17, 35, 36 telle que représentée, par exemple, sur les figures 2, 6 et 7. Les quatre câbles peuvent également être rassemblés dans une même gaine, non représentée, à leur sortie de la pièce rapportée 74.The cables are shown here coated with a sheath. It may be a standard sheath, for example polyvinyl chloride, or a sheath 17, 35, 36 as shown, for example, on figures 2 , 6 and 7 . The four cables can also be assembled in the same sheath, not shown, at their output from the insert 74.

La figure 15 représente une vue en coupe, selon la ligne II-II, de la figure 13. L'enrobage 65 vient s'accrocher à une collerette 81 solidaire de la pièce 74. Les câbles 69, 72 sont ici représentés recouverts d'une pièce 65, alors que les câbles 70 et 71, reliés à un feu de signalisation 20, ne sont pas recouverts d'une telle pièce. lls sont revêtus d'une gaine 17, 35, 36. On voit bien, sur ce schéma, que la pièce 74 n'est pas en contact avec le substrat 83, évitant la présence d'une surépaisseur sur ce dernier. Par ailleurs, la pièce auxiliaire 65 possède un resserrement 82 destiné à s'accrocher à la collerette 81. La pièce 65 est fixée au substrat à l'aide, par exemple, d'une couche adhésive ou d'un ruban adhésif non représenté(e).The figure 15 represents a sectional view along line II-II of the figure 13 . The coating 65 clings to a flange 81 secured to the piece 74. The cables 69, 72 are here shown covered with a piece 65, while the cables 70 and 71, connected to a signaling light 20, do not are not covered with such a room. They are lined with a sheath 17, 35, 36. It can clearly be seen in this diagram that the part 74 is not in contact with the substrate 83, avoiding the presence of an excess thickness on the latter. Moreover, the auxiliary piece 65 has a constriction 82 intended to hook to the flange 81. The piece 65 is fixed to the substrate using, for example, an adhesive layer or a not shown adhesive tape ( e).

La figure 16 représente différentes variantes, en coupe, de la pièce rapportée 74 selon l'invention.The figure 16 represents different variants, in section, of the insert 74 according to the invention.

Sur ce schéma, les deux pièces 65 et 85 sont sur une même face du substrat 83. Le substrat 83 peut être, éventuellement, revêtu d'une ou plusieurs couches, non représentée(s). Ces pièces peuvent être également sur les deux faces opposées du substrat 83. L'embase 85 est, par exemple, une embase fixée sur le substrat et supportant la liaison 84. Cette embase permet, en particulier, de s'affranchir des éventuels écarts de géométrie de la feuille de verre. La pièce 74 n'est pas en contact avec le substrat 83.In FIG. 16a, this part comprises a flange 81 to which a coating 65 and a base 85 engage. In this diagram, the two parts 65 and 85 are on the same face of the substrate 83. The substrate 83 can be, optionally, coated with one or more layers, not shown. These parts may also be on the two opposite faces of the substrate 83. The base 85 is, for example, a base fixed on the substrate and supporting the connection 84. This base makes it possible, in particular, to overcome any differences in geometry of the glass sheet. The part 74 is not in contact with the substrate 83.

Sur les schémas suivants 16b, 16c au moins une partie de la pièce 74 est fixée sur le substrat 83.In the following diagrams 16b, 16c at least a part of the part 74 is fixed on the substrate 83.

La pièce 74 peut être fixée à l'aide d'un renflement 86 et par une patte 87 fixée à la feuille de verre (schéma 16b). Le renflement 86 et la patte 87 peuvent être sur les deux faces opposées du substrat 83 (schéma 16b) ou sur la même face (schéma 16c).The piece 74 can be fixed by means of a bulge 86 and by a tab 87 attached to the glass sheet (diagram 16b). The bulge 86 and the lug 87 may be on the two opposite faces of the substrate 83 (diagram 16b) or on the same face (diagram 16c).

La figure 17 représente une pièce rapportée 74 profilée comportant une lèvre 92 permettant d'assurer la continuité d'une lèvre, non représentée, solidaire par ailleurs d'un joint de montage. Cette lèvre non représentée assure la protection, le centrage et le maintien du vitrage durant le temps nécessaire à la prise du cordon de colle 93 fixant le vitrage à la baie 94 de carrosserie. Le cordon de colle 93 peut, éventuellement, assurer l'étanchéité vitrage/baie.The figure 17 is a profiled insert 74 having a lip 92 to ensure the continuity of a lip, not shown, further secured to a mounting gasket. This not shown lip ensures the protection, centering and maintenance of the glazing during the time required to take the glue bead 93 fixing the glazing to the body 94 bay. The adhesive bead 93 may, optionally, ensure the glazing / bay sealing.

Ces figures sont données à titre non limitatif en tant qu'exemples de réalisation. Bien entendu, seule une partie marginale du câble peut être située dans une zone hors étanchéité.These figures are given as non-limiting examples of embodiment. Of course, only a marginal portion of the cable may be located in a non-sealing area.
