Description

ENSEMBLE DE CONNEXION D'UN BRAS D'ENTRAINEMENT D'UN BALAI D'ESSUYAGE A CONNECTION ASSEMBLY OF A DRAWING BROOM DRIVE ARM
UN ARBRE MOTEUR D'UN VEHICULE A MOTOR SHAFT OF A VEHICLE
L’invention se rapporte au domaine de l’essuyage des surfaces vitrées d’un véhicule, notamment automobile, et elle concerne plus particulièrement un ensemble de connexion permettant de relier un bras d’entrainement d’un balai d’essuyage et un arbre moteur du véhicule. The invention relates to the field of wiping glass surfaces of a vehicle, in particular a motor vehicle, and more particularly relates to a connection assembly making it possible to connect a drive arm of a wiper blade and a motor shaft. of the vehicle.
Les systèmes d’essuyage pour véhicules automobiles sont conçus pour retirer, par balayage, les liquides et salissures qui peuvent perturber la vision que le conducteur a de son environnement. Ces systèmes d’essuyage comprennent généralement au moins un bras d’entrainement entraîné en rotation par un arbre moteur du véhicule et qui effectue un mouvement de va-et-vient angulaire sur une surface vitrée du véhicule, et au moins un balai d’essuyage équipé d’une lame d’essuyage réalisée dans un matériau plastique souple et entraîné par le bras d’entrainement. En frottant contre cette surface vitrée, la lame d’essuyage racle l’eau et un certain nombre de salissures pour les évacuer en dehors du champ de vision du conducteur. Motor vehicle wiping systems are designed to sweep away liquids and soiling that can interfere with a driver’s vision of their surroundings. These wiping systems generally comprise at least one drive arm driven in rotation by a motor shaft of the vehicle and which performs an angular reciprocating movement on a glazed surface of the vehicle, and at least one wiping brush. equipped with a wiping blade made of a flexible plastic material and driven by the drive arm. By rubbing against this glass surface, the wiping blade scrapes water and a certain number of soils to evacuate them outside the driver's field of vision.
Quelle que soit la configuration du balai d’essuyage, le bras d’entrainement est relié à l’arbre moteur qui l’entraîne en rotation par l’intermédiaire d’un dispositif de fixation. Ainsi, ce dispositif de fixation participe à former une zone de fixation du bras d’entrainement sur l’arbre moteur. Pour des raisons notamment esthétiques mais également pour le risque généré par les pièces de cette zone de fixation, un capot est classiquement monté pivotant sur le dispositif de fixation. Ce capot peut prendre une position fermée dans laquelle il interdit l’accès à cette zone de fixation, masquant ainsi cette dernière, et une position ouverte dans laquelle il autorise l’accès à cette zone de fixation afin de permettre la mise en place de moyens de fixation qui permettent de fixer le dispositif de fixation sur l’arbre moteur. Whatever the configuration of the wiper blade, the drive arm is connected to the motor shaft which drives it in rotation by means of a fixing device. Thus, this fixing device participates in forming a zone for fixing the drive arm to the motor shaft. For notably aesthetic reasons but also for the risk generated by the parts of this fixing zone, a cover is conventionally pivotally mounted on the fixing device. This cover can take a closed position in which it prohibits access to this fixing zone, thus masking the latter, and an open position in which it allows access to this fixing zone in order to allow the installation of means. which allow the fixing device to be fixed on the motor shaft.
Un tel capot comprend classiquement des moyens de verrouillage de sa position fermée, c’est-à-dire la position qu’il prend une fois que le dispositif de fixation est fixé sur l’arbre moteur. Un inconvénient des capots actuels réside dans le fait qu’ils sont dépourvus de moyens de verrouillage de la position ouverte, de sorte que le positionnement des moyens de fixation assurant la liaison entre le dispositif de fixation et l’arbre moteur est complexe et nécessite l’intervention d’au moins deux personnes, l’une d’elle devant maintenir le capot pendant que l’autre positionne les moyens de fixation. Such a cover conventionally comprises means for locking its closed position, that is to say the position which it takes once the fixing device is fixed to the motor shaft. A disadvantage of the current covers is that they do not have means for locking the open position, so that the positioning of the fixing means ensuring the connection between the fixing device and the motor shaft is complex and requires the intervention of at least two people, one of them having to hold the cover while the other positions the fixing means.
La présente invention s’inscrit dans ce contexte et propose un moyen simple et peu coûteux permettant de maintenir le capot dans sa position ouverte afin qu’une personne seule soit capable de fixer le bras d’entrainement sur l’arbre moteur, aussi bien en première monte qu’en cas de changement de ce bras d’entrainement au cours de la vie du véhicule. The present invention is in this context and provides a simple and inexpensive means for keeping the hood in its open position so that a single person is able to fix the drive arm on the motor shaft, both in original equipment only in case of change of this drive arm during the life of the vehicle.
Un objet de la présente invention concerne ainsi un ensemble de connexion d’un bras d’entrainement d’un balai d’essuyage à un arbre moteur d’un véhicule, l’ensemble de connexion comprenant au moins un dispositif de fixation configuré pour lier en rotation le bras d’entrainement avec l’arbre moteur et au moins un capot monté pivotant sur le dispositif de fixation, le capot étant configuré pour prendre une position fermée dans laquelle il interdit un accès à une zone de fixation entre le dispositif de fixation et l’arbre moteur ou une position ouverte dans laquelle il autorise l’accès à la zone de fixation entre le dispositif de fixation et l’arbre moteur. Selon l’invention, l’ensemble de connexion comprend au moins un dispositif de verrouillage de la position ouverte du capot, ce dispositif de verrouillage comprenant au moins un premier élément et au moins un deuxième élément répartis entre le capot et le dispositif de fixation, le premier élément et le deuxième élément du dispositif de verrouillage étant configurés pour verrouiller par frottement la position ouverte du capot. An object of the present invention thus relates to a connection assembly of a drive arm of a wiper blade to a motor shaft of a vehicle, the connection assembly comprising at least one fixing device configured to link in rotation the drive arm with the motor shaft and at least one cover pivotally mounted on the fixing device, the cover being configured to assume a closed position in which it prevents access to a fixing zone between the fixing device and the drive shaft or an open position in which it allows access to the attachment zone between the attachment device and the drive shaft. According to the invention, the connection assembly comprises at least one device for locking the open position of the cover, this locking device comprising at least a first element and at least a second element distributed between the cover and the fixing device, the first element and the second element of the locking device being configured to lock the open position of the cover by friction.
Autrement dit, on comprend qu’une zone de frottement ou une zone de contact est crée entre le premier élément et le deuxième élément du dispositif de verrouillage notamment lors de l’ouverture du capot, au moins lorsque ce capot est dans sa position ouverte, cette zone de frottement ou cette zone de contact permettant le maintien du capot dans sa position ouverte. In other words, it is understood that a friction zone or a contact zone is created between the first element and the second element of the locking device, in particular when the cover is opened, at least when this cover is in its open position, this friction zone or this contact zone allowing the cover to be maintained in its open position.
On entend ici par « frottement » le fait que le premier élément et le deuxième élément du dispositif de verrouillage sont en appui l’un contre l’autre, générant ainsi un effort de maintien lorsque le capot est dans sa position ouverte. Il est entendu que ce dispositif de verrouillage est réversible, pour sortir de la position ouverte sans dégradation des éléments. The term “friction” is understood here to mean the fact that the first element and the second element of the locking device are in abutment against one another, thus generating a holding force when the cover is in its open position. It is understood that this locking device is reversible, to exit the open position without degradation of the elements.
Selon un exemple d’application de la présente invention, le premier élément du dispositif de verrouillage est ménagé sur le dispositif de fixation et le deuxième élément du dispositif de verrouillage est ménagé sur le capot. Alternativement, on pourra prévoir que le premier élément du dispositif de verrouillage soit ménagé sur le capot et que le deuxième élément de ce dispositif de verrouillage soit ménagé sur le dispositif de fixation. According to an example of application of the present invention, the first element of the locking device is formed on the fixing device and the second element of the locking device is formed on the cover. Alternatively, provision may be made for the first element of the locking device to be provided on the cover and for the second element of this locking device to be provided on the fixing device.
Selon une caractéristique de la présente invention, le capot est monté pivotant sur le dispositif de fixation par l’intermédiaire d’une liaison pivot qui comprend au moins un toron reçu dans un alésage, le toron s’étendant depuis un socle et au moins une portion du socle formant le deuxième élément du dispositif de verrouillage. Avantageusement, le dispositif de verrouillage de la position ouverte du capot est ménagé au voisinage de cette liaison pivot. Selon l’invention, le socle depuis lequel s’étend le toron peut être ménagé sur le capot de l’ensemble de connexion. Alternativement, on pourra prévoir que ce socle soit ménagé sur le dispositif de fixation. According to a characteristic of the present invention, the cover is pivotally mounted on the fixing device via a pivot connection which comprises at least one strand received in a bore, the strand extending from a base and at least one portion of the base forming the second element of the locking device. Advantageously, the device for locking the open position of the cover is arranged in the vicinity of this pivot connection. According to the invention, the base from which the strand extends can be formed on the cover of the connection assembly. Alternatively, provision may be made for this base to be provided on the fixing device.
Selon un premier exemple de réalisation de la présente invention, le premier élément du dispositif de verrouillage est formé par une portion d’une paroi dans laquelle est ménagé l’alésage de la liaison pivot et une surépaisseur est ménagée sur le socle du toron, cette surépaisseur formant le deuxième élément du dispositif de verrouillage. On comprend que lorsque le socle du toron est ménagé sur le capot, le premier élément du dispositif de verrouillage est formé par une portion d’une paroi du dispositif de fixation dans laquelle est ménagé l’alésage qui reçoit ce toron. Alternativement, lorsque le socle du toron est ménagé sur le dispositif de fixation, le premier élément du dispositif de verrouillage est formé par une portion d’une paroi du capot dans laquelle est ménagé l’alésage qui reçoit ce toron. Selon une caractéristique de ce premier exemple de réalisation, la surépaisseur s’étend majoritairement depuis le toron jusqu’à un bord avant du socle de ce toron. Selon cette caractéristique du premier exemple de réalisation de la présente invention, la surépaisseur s’étend parallèlement à un plan dans lequel s’inscrit majoritairement le socle. On entend par « bord avant » un bord le plus proche du bras d’entrainement lorsque l’ensemble de connexion est assemblé sur un tel bras d’entrainement et que le capot est dans sa position fermée. According to a first embodiment of the present invention, the first element of the locking device is formed by a portion of a wall in which is formed the bore of the pivot connection and an additional thickness is provided on the base of the strand, this extra thickness forming the second element of the locking device. It is understood that when the base of the strand is formed on the cover, the first element of the locking device is formed by a portion of a wall of the fixing device in which the bore which receives this strand is formed. Alternatively, when the base of the strand is formed on the fixing device, the first element of the locking device is formed by a portion of a wall of the cover in which is formed the bore which receives this strand. According to a characteristic of this first embodiment, the extra thickness extends mainly from the strand to a front edge of the base of this strand. According to this characteristic of the first embodiment of the present invention, the extra thickness extends parallel to a plane in which the majority of the base is inscribed. “Front edge” means an edge closest to the arm drive when the connection assembly is assembled on such a drive arm and the cover is in its closed position.
Selon le premier exemple de réalisation de la présente invention, la surépaisseur est ménagée à une distance non nulle d’un bord inférieur du socle. On entend par « bord inférieur du socle » un bord de ce socle tourné vers le dispositif de fixation lorsque le capot est dans sa position fermée. Selon l’invention, ce bord inférieur du socle s’étend perpendiculairement, ou sensiblement perpendiculairement au bord avant de ce socle. Avantageusement, cette distance non nulle ménagée entre la surépaisseur et le bord inférieur du socle permet au capot de pivoter par rapport au dispositif de fixation afin de passer de sa position ouverte à sa position fermée ou de sa position fermée à sa position ouverte. According to the first embodiment of the present invention, the extra thickness is provided at a non-zero distance from a lower edge of the base. The term “lower edge of the base” means an edge of this base turned towards the fixing device when the cover is in its closed position. According to the invention, this lower edge of the base extends perpendicularly, or substantially perpendicular to the front edge of this base. Advantageously, this non-zero distance provided between the additional thickness and the lower edge of the base allows the cover to pivot relative to the fixing device in order to pass from its open position to its closed position or from its closed position to its open position.
Selon ce premier exemple de réalisation, la surépaisseur peut être issue de matière avec le toron. En d’autres termes, le toron et la surépaisseur forment alors un ensemble monobloc, c’est-à-dire un ensemble qui ne peut être séparé sans entraîner la détérioration du toron ou de la surépaisseur. According to this first exemplary embodiment, the additional thickness can be made from material with the strand. In other words, the strand and the extra thickness then form a one-piece assembly, that is to say an assembly that cannot be separated without causing the deterioration of the strand or the extra thickness.
On comprend donc que, selon le premier exemple de réalisation de la présente invention, un frottement s’opère entre la surépaisseur et la paroi dans laquelle est ménagé l’alésage qui reçoit le toron de la liaison pivot et que ce frottement permet de bloquer le capot dans sa position ouverte, c’est-à-dire dans la position dans laquelle la zone de fixation du dispositif de fixation sur l’arbre moteur est accessible. Plus particulièrement, ce frottement entraîne une déformation du capot et c’est cette déformation qui assure le blocage de la position ouverte du capot. En outre, ce blocage de la position ouverte du capot étant réalisé par frottement, on comprend qu’il est facilement réversible afin de permettre de faire passer le capot de sa position ouverte à sa position fermée, c’est-à-dire une position dans laquelle la zone de fixation est protégée. It is therefore understood that, according to the first embodiment of the present invention, friction takes place between the additional thickness and the wall in which the bore is formed which receives the strand of the pivot link and that this friction makes it possible to block the hood in its open position, that is to say in the position in which the fixing zone of the fixing device on the motor shaft is accessible. More particularly, this friction causes a deformation of the cover and it is this deformation which ensures the blocking of the open position of the cover. In addition, this blocking of the open position of the cover being produced by friction, it is understood that it is easily reversible in order to allow the cover to pass from its open position to its closed position, that is to say a position in which the fixing area is protected.
Selon un deuxième exemple de réalisation de la présente invention, une paroi dans laquelle est ménagé l’alésage de la liaison pivot comprend au moins un plot, une portion de ce plot formant le premier élément du dispositif de verrouillage du capot en position ouverte. Tel que précédemment mentionné, l’alésage peut être ménagé dans une paroi latérale du dispositif de fixation. Alternativement, cet alésage peut être ménagé dans une paroi du capot. Tel que précédemment évoqué, le deuxième élément du dispositif de verrouillage est formé, quel que soit l’exemple de réalisation de la présente invention, par une portion du socle duquel est issu le toron de la liaison pivot. Selon le deuxième exemple de réalisation, la portion du socle formant ce deuxième élément du dispositif de verrouillage est formée par le bord avant de ce socle. Optionnellement, on pourra prévoir que le bord avant du socle présente un chanfrein. According to a second embodiment of the present invention, a wall in which the bore of the pivot link is formed comprises at least one stud, a portion of this stud forming the first element of the device for locking the cover in the open position. As previously mentioned, the bore can be formed in a side wall of the fixing device. Alternatively, this bore may be formed in a wall of the cover. As previously mentioned, the second element of the locking device is formed, whatever the embodiment of the present invention, by a portion of the base from which the strand of the pivot connection comes. According to the second embodiment, the portion of the base forming this second element of the locking device is formed by the front edge of this base. Optionally, provision may be made for the front edge of the base to have a chamfer.
Selon une caractéristique de ce deuxième exemple de réalisation, le plot prend une forme sensiblement tétraédrique, la portion du plot formant le premier élément du dispositif de verrouillage étant une face supérieure de ce plot, cette face supérieure étant la face de ce plot la plus proche de l’alésage de la liaison pivot. Autrement dit, le bord avant du socle vient frotter contre la face supérieure du plot et ce frottement génère un appui radial du toron dans son alésage, assurant ainsi le maintien du capot en position ouverte. On comprend que, lorsque le bord avant est chanfreiné, ce chanfrein facilite le frottement entre la face supérieure du plot et ce bord avant de sorte que le verrouillage de la position ouverte du capot soit facilité. De façon analogue au premier exemple de réalisation, ce verrouillage par frottement est réversible de sorte que le capot puisse être déplacé de sa position ouverte à sa position fermée, une fois que les moyens de fixation du dispositif de fixation sur l’arbre moteur sont en position. According to a characteristic of this second embodiment, the stud takes a substantially tetrahedral shape, the portion of the stud forming the first element of the locking device being an upper face of this stud, this upper face being the face of this stud closest of the bore of the pivot link. In other words, the front edge of the base rubs against the upper face of the stud and this friction generates a radial support of the strand in its bore, thus ensuring the maintenance of the cover in the open position. It is understood that, when the front edge is chamfered, this chamfer facilitates friction between the upper face of the stud and this front edge so that the locking of the open position of the cover is facilitated. Similarly to the first embodiment, this friction locking is reversible so that the cover can be moved from its open position to its closed position, once the means for fixing the fixing device to the motor shaft are in position.
L’invention concerne également un bras d’entrainement d’un balai d’essuyage destiné à un véhicule, le bras d’entrainement comprenant au moins un ensemble de connexion selon l’invention, cet ensemble de connexion étant configuré pour relier le bras d’entrainement à un arbre moteur du véhicule. La présente invention concerne enfin un système d’essuyage comprenant au moins un balai d’essuyage destiné à venir au contact d’une surface vitrée d’un véhicule automobile, au moins un bras d’entrainement selon l’invention configuré pour entraîner en rotation le balai d’essuyage et au moins un dispositif de connexion reliant le balai d’essuyage au bras d’entrainement, ce bras d’entrainement étant relié à un arbre moteur du véhicule par l’ensemble de connexion selon la présente invention. Selon un exemple d’application de la présente invention, le balai d’essuyage est destiné à venir au contact d’une lunette arrière du véhicule. The invention also relates to a drive arm of a wiper blade intended for a vehicle, the drive arm comprising at least one connection assembly according to the invention, this connection assembly being configured to connect the arm of drive to a motor shaft of the vehicle. The present invention finally relates to a wiping system comprising at least one wiper blade intended to come into contact with a glazed surface of a motor vehicle, at least one drive arm according to the invention configured to drive in rotation the wiper blade and at least one connection device connecting the wiper blade to the drive arm, this drive arm being connected to a motor shaft of the vehicle by the connection assembly according to the present invention.

In the following description, the longitudinal or transverse designations refer to the orientation of a device for fixing a connection assembly according to the invention. The longitudinal direction corresponds to a main extension direction of the fixing device, this longitudinal direction being parallel to a longitudinal axis L of a trihedron L, V, T illustrated in the figures, a transverse direction corresponds to a direction parallel to a transverse axis T of this trihedron, this transverse axis T being perpendicular to the longitudinal axis L. A vertical direction corresponds to a direction parallel to a vertical axis V of the trihedron, the vertical axis V being perpendicular to the axis longitudinal L and transverse axis T.
Les dénominations « supérieur », « inférieur », « dessus » et « dessous » se réfèrent à une orientation de l’ensemble de connexion lorsque celui-ci est intégré à un système d’essuyage sur un véhicule, les termes « supérieur » et « dessus » faisant référence à des positions le long de l’axe vertical V du trièdre les plus éloignées d’une surface vitrée du véhicule destinée à être essuyée par le système d’essuyage, et les termes « inférieur » et « dessous » faisant référence à des positions le long de l’axe vertical V les plus proches de cette surface vitrée. Les dénominations « avant » et « arrière » se réfèrent quant à elles à une orientation de l’ensemble de connexion lorsque celui-ci est intégré au système d’essuyage du véhicule, le terme « avant » faisant référence à une position, le long de l’axe longitudinal, la plus proche du bras d’entrainement du système d’essuyage lorsque ce bras d’entrainement est fixé à l’ensemble de connexion et le terme « arrière » faisant référence à une position, le long de l’axe longitudinal, la plus proche d’un arbre moteur du véhicule, lorsque l’ensemble de connexion est fixé sur cet arbre moteur. The names “upper”, “lower”, “above” and “below” refer to an orientation of the connection assembly when it is integrated into a wiping system on a vehicle, the terms “upper” and "Above" referring to positions along the vertical axis V of the trihedron farthest from a glazed surface of the vehicle intended to be wiped by the wiping system, and the terms "lower" and "below" making reference to positions along the vertical axis V closest to this glazed surface. The names “front” and “rear” refer to an orientation of the connection assembly when it is integrated into the wiping system of the vehicle, the term “front” referring to a position, along from the longitudinal axis, closest to the drive arm of the wiping system when this drive arm is attached to the connection assembly and the term "rear" referring to a position, along the longitudinal axis, closest to a motor shaft of the vehicle, when the connection assembly is fixed to this motor shaft.
Les coupes transversales mentionnées ci-après sont réalisées selon des plans de coupe dans lesquels s’inscrivent l’axe transversal T et l’axe vertical V du trièdre illustré sur les figures. Les coupes longitudinales sont quant à elles réalisées selon un plan dans lequel s’inscrivent l’axe longitudinal L et l’axe vertical V du trièdre illustré sur les figures. The transverse sections mentioned below are produced according to cutting planes in which the transverse axis T and the vertical axis V of the trihedron illustrated in the figures are inscribed. The longitudinal sections are made according to a plane in which the longitudinal axis L and the vertical axis V of the trihedron illustrated in the figures are inscribed.
En référence à la figure t, un véhicule automobile est couramment équipé d’un système d’essuyage too pour évacuer une eau et/ou des salissures présentes sur une surface vitrée 1, notamment une lunette arrière ou un pare-brise de véhicule automobile. Le système d’essuyage 100 comprend un balai d’essuyage toi qui comprend au moins un déflecteur d’air 102 et une lame racleuse 103 reliés l’un à l’autre par un élément de structure 104 du balai d’essuyage 101, ce dernier étant alors dépourvu de palonniers. Un tel élément de structure 104 peut par exemple être formé par un unique organe de flexion, ou par une pluralité d’organes de flexion ou encore par un support dans lequel sont enfilés un ou plusieurs organes de flexion. Referring to Figure t, a motor vehicle is commonly equipped with a wiping system too to evacuate water and / or dirt present on a glazed surface 1, in particular a rear window or a motor vehicle windshield. The wiping system 100 comprises a wiping brush you which comprises at least one air deflector 102 and a scraper blade 103 connected to each other by a structural element 104 of the wiping brush 101, this the latter then having no spreaders. Such a structural element 104 can for example be formed by a single flexing member, or by a plurality of flexing members or also by a support in which one or more flexing members are threaded.
Le déflecteur d’air 102 est prévu pour transformer une pression appliquée par un flux d’air circulant le long de la surface vitrée 1 en une force d’appui du balai d’essuyage 101 contre la surface vitrée 1 du véhicule automobile. La lame racleuse 103 est la pièce du balai d’essuyage 101 en contact direct avec la surface vitrée 1 et elle est configurée pour évacuer l’eau et/ou les salissures présentes sur cette dernière. Selon l’exemple illustré, le déflecteur d’air 102, la lame racleuse 103 et l’élément de structure 104 forment un ensemble semi-rigide porté par un dispositif de fixation 105, interposé entre un bras d’entraînement 106 et le balai d’essuyage 101. Alternativement, on pourra prévoir que le balai d’essuyage soit directement relié au bras d’entrainement. The air deflector 102 is designed to transform a pressure applied by a flow of air flowing along the glass surface 1 into a force for pressing the wiper blade 101 against the glass surface 1 of the motor vehicle. The scraper blade 103 is the part of the wiper blade 101 in direct contact with the glass surface 1 and it is configured to evacuate the water and / or the dirt present on the latter. According to the example illustrated, the air deflector 102, the scraper blade 103 and the structural element 104 form a semi-rigid assembly carried by a fixing device 105, interposed between a drive arm 106 and the brush d wiping 101. Alternatively, provision may be made for the wiping brush to be directly connected to the drive arm.
Le bras d’entraînement 106 est apte à effectuer un mouvement de va-et-vient angulaire le long de la surface vitrée 1, entraînant avec lui le balai d’essuyage 101. Selon l’invention, le bras d’entrainement 106 est lié en rotation à un arbre moteur 107 du véhicule par un ensemble de connexion 200 selon la présente invention. Tel que cela sera plus amplement détaillé ci-après, cet ensemble de connexion 200 comprend au moins un dispositif de fixation qui assure la liaison mécanique entre le bras d’entrainement 106 et l’arbre moteur 107 et un capot monté en rotation sur le dispositif de fixation, le capot étant agencé au-dessus du dispositif de fixation lorsque l’ensemble de connexion est intégré au système d’essuyage. Le capot permet, en plus d’une fonction esthétique, de protéger une zone de fixation 300 du dispositif de fixation sur l’arbre moteur 107. Selon l’invention, une liaison pivot est ainsi ménagée entre le dispositif de fixation et le capot de l’ensemble de connexion 200. Tel que cela sera plus amplement détaillé ci-après, cette liaison pivot comprend au moins un toron reçu dans un alésage. Le capot 210 est ainsi mobile par rapport au dispositif de fixation 220 et il peut prendre une position ouverte PO ou une position fermée PF respectivement illustrées sur les figures 2 et 3. La position ouverte PO du capot 210 correspond à une position dans laquelle la zone de fixation 300 du dispositif de fixation 220 sur l’arbre moteur 107 est accessible et la position fermée PF de ce capot 210 correspond quant à elle à une position dans laquelle le capot 210 recouvre la zone de fixation 300 du dispositif de fixation 220 sur l’arbre moteur 107. The drive arm 106 is able to perform an angular back-and-forth movement along the glass surface 1, carrying with it the wiper blade 101. According to the invention, the drive arm 106 is linked in rotation to a motor shaft 107 of the vehicle by a connection assembly 200 according to the present invention. As will be explained in more detail below, this connection assembly 200 comprises at least one fixing device which provides the mechanical connection between the drive arm 106 and the motor shaft 107 and a cover rotatably mounted on the device fixing, the cover being arranged above the fixing device when the connection assembly is integrated into the wiping system. The cover makes it possible, in addition to an aesthetic function, to protect a fixing zone 300 of the fixing device on the motor shaft 107. According to the invention, a pivot link is thus formed between the fixing device and the cover. the connection assembly 200. As will be explained in more detail below, this pivot connection comprises at least one strand received in a bore. The cover 210 is thus movable relative to the fixing device 220 and it can take an open position PO or a closed position PF respectively illustrated in FIGS. 2 and 3. The open position PO of the cover 210 corresponds to a position in which the zone fixing 300 of the fixing device 220 on the motor shaft 107 is accessible and the closed position PF of this cover 210 corresponds to a position in which the cover 210 covers the fixing zone 300 of the fixing device 220 on the motor shaft 107.
Il est entendu que le système d’essuyage 100 qui vient d’être décrit n’est qu’un exemple et que l’ensemble de connexion 200 selon la présente invention peut être utilisé sur tout type de système d’essuyage, par exemple un système d’essuyage dans lequel le bras d’entrainement est relié au balai d’essuyage par des palonniers, c’est-à-dire un système d’essuyage dépourvu de l’élément de structure 104. It is understood that the wiping system 100 which has just been described is only an example and that the connection assembly 200 according to the present invention can be used on any type of wiping system, for example a wiping system in which the drive arm is connected to the wiping brush by lifting beams, that is to say a wiping system devoid of the structural element 104.
En référence à ces figures 2 et 3, nous allons maintenant décrire plus en détails l’ensemble de connexion 200 selon la présente invention, la figure 2 étant une vue de dessus, en perspective, de l’ensemble de connexion 200 lorsque le capot 210 dans sa position ouverte PO et la figure 3 est une vue de dessous, en perspective, de l’ensemble de connexion 200 lorsque le capot 210 dans sa position fermée PF. Le dispositif de fixation 220 permet de créer une liaison mécanique entre le bras d’entrainement et l’arbre moteur et comprend à cet effet au moins un palier 221 configuré pour recevoir l’arbre moteur et au moins un arbre 222 sur lequel le bras d’entrainement peut être fixé. Tel qu’illustré, le dispositif de fixation 220 s’étend majoritairement selon une direction d’extension principale D parallèle à l’axe longitudinal L du trièdre, le palier 221 et l’arbre 222 étant opposés l’un à l’autre le long de cette direction d’extension principale D. Referring to these Figures 2 and 3, we will now describe in more detail the connection assembly 200 according to the present invention, Figure 2 being a top view, in perspective, of the connection assembly 200 when the cover 210 in its open position PO and FIG. 3 is a bottom view, in perspective, of the connection assembly 200 when the cover 210 in its closed position PF. The fixing device 220 makes it possible to create a mechanical connection between the drive arm and the drive shaft and for this purpose comprises at least one bearing 221 configured to receive the drive shaft and at least one shaft 222 on which the drive arm drive can be fixed. As illustrated, the fixing device 220 mainly extends in a main direction of extension D parallel to the longitudinal axis L of the trihedron, the bearing 221 and the shaft 222 being opposite to each other the along this main extension direction D.
Tel qu’illustré sur les figures 2 et 3, l’arbre 222 s’étend entre deux parois latérales 223 du dispositif de fixation 220, et selon une direction perpendiculaire, ou sensiblement perpendiculaire à la direction d’extension principale D de ce dispositif de fixation 220, c’est-à-dire parallèlement à l’axe transversal T du trièdre illustré. Ces parois latérales 223 sont en outre porteuses d’au moins une partie de io la liaison pivot 6oo ménagée entre le dispositif de fixation 220 et le capot 210. Les deux parois latérales 223 du dispositif de fixation 220 sont reliées entre elles, d’une part par une paroi inférieure 225 et d’autre part par une paroi supérieure 227, la paroi inférieure 225 étant tournée vers la surface vitrée lorsque l’ensemble de connexion 200 est intégré au véhicule et la paroi supérieure 227 étant tournée vers le capot 210. On remarque sur les figures 2 et 3 qu’une face inférieure 228 du palier 221 s’étend dans un même plan longitudinal et transversal que la paroi inférieure 225 du dispositif de fixation 220. En revanche, un plan dans lequel s’inscrit une face supérieure 229 du palier 221 et un plan dans lequel s’inscrit majoritairement la paroi supérieure 227 du dispositif de fixation 220 sont distincts, le plan dans lequel s’inscrit la face supérieure 229 du palier 221 et le plan dans lequel s’inscrit majoritairement la paroi supérieure 227 du dispositif de fixation 220 étant décalés l’une par rapport à l’autre le long de l’axe vertical V. As illustrated in FIGS. 2 and 3, the shaft 222 extends between two side walls 223 of the fastening device 220, and in a direction perpendicular, or substantially perpendicular to the main extension direction D of this device. attachment 220, that is to say parallel to the transverse axis T of the trihedron illustrated. These side walls 223 are also carrying at least part of io the pivot link 6oo formed between the fixing device 220 and the cover 210. The two side walls 223 of the fixing device 220 are interconnected, on the one hand by a lower wall 225 and on the other hand by an upper wall 227, the lower wall 225 being turned towards the glazed surface when the connection assembly 200 is integrated into the vehicle and the upper wall 227 being turned towards the cover 210. It can be seen in FIGS. 2 and 3 that a lower face 228 of bearing 221 extends in the same longitudinal and transverse plane as the lower wall 225 of the fixing device 220. On the other hand, a plane in which an upper face 229 of the bearing 221 is inscribed and a plane in which the predominantly the upper wall 227 of the fixing device 220 are distinct, the plane in which the upper face 229 of the bearing 221 is inscribed and the plane in which the upper wall 227 of the device is inscribed fixing point 220 being offset relative to each other along the vertical axis V.
Tel que représenté, un orifice 224 est ménagé dans le palier 221 et on comprend que c’est dans cet orifice 224 qu’est destiné à être reçu l’arbre moteur du véhicule. Lorsque l’on souhaite fixer l’ensemble de connexion 200 selon l’invention sur l’arbre moteur, on comprend que cet arbre moteur est ainsi inséré dans l’orifice 224 ménagé dans le palier 221 du dispositif de connexion 220, par dessous, c’est-à- dire que l’orifice 224 débouche sur la face inférieure 228 du palier 221 et que c’est par cette face inférieure 228 que l’arbre moteur est inséré dans le palier 221. Une fois l’arbre moteur inséré dans l’orifice 224, au moins un moyen de fixation est mis en place, afin de maintenir l’arbre moteur en position dans cet orifice 224. Autrement dit, le palier 221 du dispositif de fixation 220, et plus particulièrement l’orifice 224 ménagé dans ce palier 221, participe à former la zone de fixation 300 du dispositif de fixation 220 sur l’arbre moteur. Selon l’exemple illustré ici, le palier 221 est circulaire mais il pourrait prendre toute autre forme sans sortir du contexte de la présente invention. As shown, an orifice 224 is formed in the bearing 221 and it is understood that it is in this orifice 224 that is intended to be received the engine shaft of the vehicle. When it is desired to fix the connection assembly 200 according to the invention to the motor shaft, it is understood that this motor shaft is thus inserted into the orifice 224 formed in the bearing 221 of the connection device 220, from below, that is to say that the orifice 224 opens onto the lower face 228 of the bearing 221 and that it is by this lower face 228 that the motor shaft is inserted into the bearing 221. Once the motor shaft is inserted in the orifice 224, at least one fixing means is put in place, in order to keep the motor shaft in position in this orifice 224. In other words, the bearing 221 of the fixing device 220, and more particularly the orifice 224 formed in this bearing 221, participates in forming the fixing zone 300 of the fixing device 220 on the motor shaft. According to the example illustrated here, the bearing 221 is circular but it could take any other form without departing from the context of the present invention.
Tel que représenté sur la figure 3, le dispositif de connexion 220 comprend en outre une tige 116 qui s’étend sensiblement parallèlement à l’arbre 222 entre les deux parois latérales 223 du dispositif de fixation 220. Cette tige 116 est destinée à recevoir un crochet d’un dispositif de rappel élastique configuré pour plaquer le balai d’essuyage sur la surface vitrée à nettoyer. Autrement dit, dans l’exemple illustré ici, ce dispositif de rappel élastique exerce une force d’appui sur le balai d’essuyage par l’intermédiaire de l’élément de structure qui permet de répartir cette force sur toute une longueur de ce balai d’essuyage. On remarque également qu’un ajour 126 est ménagé dans la paroi inférieure 225 du dispositif de fixation 220, autour de cette tige 116. On comprend que cet ajour 126 est configuré pour permettre l’assemblage du crochet du dispositif de rappel élastique sur la tige 116. As shown in Figure 3, the connection device 220 further comprises a rod 116 which extends substantially parallel to the shaft 222 between the two side walls 223 of the fixing device 220. This rod 116 is intended to receive a hook of an elastic return device configured to press the wiper blade onto the glass surface to be cleaned. In other words, in the example illustrated here, this elastic return device exerts a bearing force on the wiper blade by means of the structural element which makes it possible to distribute this force over a whole length of this wiper blade. We also note that an opening 126 is formed in the lower wall 225 of the fixing device 220, around this rod 116. It is understood that this opening 126 is configured to allow assembly of the hook of the elastic return device on the rod 116.
Dans sa généralité, le capot 210 s’étend quant à lui selon un axe d’extension principal X. Tel qu’illustré sur les figures 2 et 3, cet axe d’extension principal X est parallèle à la direction principale d’extension D du dispositif de fixation 220 lorsqu’il est dans sa position fermée PF et cet axe d’extension principal X est oblique par rapport à cette direction principale d’extension D du dispositif de fixation 220 lorsqu’il est dans sa position ouverte PO. Ce capot 210 comprend une paroi périphérique 211 qui délimite un volume interne 212 de ce capot 210. Vue de dessous, cette paroi périphérique 211 présente une forme en U partiellement fermée par une paroi de fond 213. Autrement dit, le capot 210 comprend au moins deux branches 214 reliées entre elles par une base 215 d’une part et par la paroi de fond 213 d’autre part. Tel que représenté, la paroi de fond 213 présente un évidement 216 qui permet de laisser accessible l’arbre 222 du dispositif de fixation 220 destiné à recevoir le bras d’entrainement. On comprend donc que le bras d’entrainement peut être changé à tout moment sans qu’aucune opération ne soit nécessaire sur le capot 210. Les branches 214 du capot 210 sont quant à elles agencées de part et d’autre des parois latérales 223 du dispositif de fixation 220 et portent au moins une partie de la liaison pivot 600 ménagée entre le capot 210 et le dispositif de fixation 220. Autrement dit, l’articulation du capot 210 par rapport au dispositif de fixation 220 se fait dans une zone où se chevauchent les branches 214 du capot 210 et les parois latérales 223 du dispositif de fixation 220. In general, the cover 210 extends in turn along a main extension axis X. As illustrated in Figures 2 and 3, this main extension axis X is parallel to the main direction of extension D of the fixing device 220 when it is in its closed position PF and this main extension axis X is oblique with respect to this main direction of extension D of the fixing device 220 when it is in its open position PO. This cover 210 comprises a peripheral wall 211 which delimits an internal volume 212 of this cover 210. Viewed from below, this peripheral wall 211 has a U-shape partially closed by a bottom wall 213. In other words, the cover 210 comprises at least two branches 214 connected together by a base 215 on the one hand and by the bottom wall 213 on the other. As shown, the bottom wall 213 has a recess 216 which allows the shaft 222 of the fixing device 220 intended to receive the drive arm to be accessible. It is therefore understood that the drive arm can be changed at any time without any operation being necessary on the cover 210. The branches 214 of the cover 210 are in turn arranged on either side of the side walls 223 of the fixing device 220 and carry at least part of the pivot link 600 formed between the cover 210 and the fixing device 220. In other words, the articulation of the cover 210 relative to the fixing device 220 takes place in an area where overlap the branches 214 of the cover 210 and the side walls 223 of the fixing device 220.
Tel qu’évoqué ci-dessus, le capot 210 peut prendre la position ouverte PO, illustrée sur la figure 2, dans laquelle la zone de fixation 300 du dispositif de fixation 220 sur l’arbre moteur est accessible et une position fermée PF, illustrée sur la figure 3, dans laquelle le capot 210 recouvre totalement au moins cette zone de fixation 300 de sorte notamment à protéger cette zone de fixation 300 et à éviter que le dispositif de fixation 220 ne se désolidarise de l’arbre moteur. Avantageusement, le volume interne 212 du capot 210 est ainsi configuré pour permettre un rabattement du capot 210 sur le dispositif de fixation 220. Selon un exemple illustré ici, ce volume interne 212 est apte à contenir l’intégralité du dispositif de fixation 220. As mentioned above, the cover 210 can take the open position PO, illustrated in FIG. 2, in which the fixing zone 300 of the fixing device 220 on the motor shaft is accessible and a closed position PF, illustrated in FIG. 3, in which the cover 210 completely covers at least this fixing zone 300 so as in particular to protect this fixing zone 300 and to prevent the fixing device 220 from becoming detached from the motor shaft. Advantageously, the internal volume 212 of the cover 210 is thus configured to allow the cover 210 to be folded down on the fixing device 220. According to an example illustrated here, this internal volume 212 is able to contain the entire fixing device 220.
L’ensemble de connexion 200 selon la présente invention comprend en outre au moins un dispositif de verrouillage de la position ouverte PO du capot 210. Selon l’invention, le verrouillage de la position ouverte PO du capot 210 grâce au dispositif de verrouillage rend notamment la zone de fixation 300 accessible sans que le capot 210 n’est à être maintenu par un opérateur, facilitant ainsi la mise en place du/des moyen(s) de fixation permettant de fixer le dispositif de fixation 220 sur l’arbre moteur du véhicule. Tel que cela sera décrit plus amplement ci-après en référence aux figures 4 à 9, le dispositif de verrouillage est ménagé au voisinage de la liaison pivot 600 ménagée entre le dispositif de fixation 220 et le capot 210. The connection assembly 200 according to the present invention further comprises at least one device for locking the open position PO of the cover 210. According to the invention, locking the open position PO of the cover 210 by means of the locking device makes in particular the fixing area 300 accessible without the cover 210 being held by an operator, thus facilitating the installation of the fixing means (s) making it possible to fix the fixing device 220 on the motor shaft of the vehicle. As will be described more fully below with reference to FIGS. 4 to 9, the locking device is arranged in the vicinity of the pivot link 600 formed between the fixing device 220 and the cover 210.
L’ensemble de connexion 200 selon l’invention comprend également un moyen de verrouillage 400 de la position fermée PF du capot 210 qui permet quant à lui de protéger la zone de fixation 300, et ce quelle que soit la vitesse de déplacement du véhicule sur lequel est monté un tel ensemble de connexion 200. Selon l’exemple illustré ici, le moyen de verrouillage 400 comprend une première nervure 401 et deux deuxièmes nervures 402 ménagées sur le capot 210, et au moins deux ergots 403 configurés pour former butée aux deux deuxième nervures 402 ainsi qu’une surface d’appui 404 destinée à recevoir la première nervure 401. The connection assembly 200 according to the invention also comprises a means for locking 400 of the closed position PF of the cover 210 which in turn makes it possible to protect the fixing zone 300, regardless of the speed of movement of the vehicle on which is mounted such a connection assembly 200. According to the example illustrated here, the locking means 400 comprises a first rib 401 and two second ribs 402 formed on the cover 210, and at least two lugs 403 configured to form a stop for the two second ribs 402 and a bearing surface 404 intended to receive the first rib 401.
Tel qu’illustré, la première nervure 401 et les deux deuxièmes nervures 402 s’étendent toutes les trois dans le volume interne 212 du capot 210. La première nervure 401 comprend une encoche 411 destinée à venir en butée contre la surface d’appui 404 évoquée ci-dessus. Cette surface d’appui 404 s’étend sur un pourtour du palier 221, de sorte que la première nervure 401 peut être ménagée en n’importe quel point de la base 215 de la forme de U que prend le capot 210. Avantageusement, la coopération de l’encoche 411 ménagée sur la première nervure 401 avec la surface d’appui 404 permet de limiter un déplacement du capot 210 du haut vers le bas, c’est-à-dire un déplacement qui permet de rabattre ce capot 210 sur le dispositif de fixation 220. Selon l’exemple illustré ici, cette surface d’appui 404 est plane mais elle pourrait également être irrégulière, et par exemple présenter un cran de réception de l’encoche ménagée sur la première nervure sans sortir du contexte de la présente invention. As illustrated, the first rib 401 and the two second ribs 402 all extend in the internal volume 212 of the cover 210. The first rib 401 comprises a notch 411 intended to come into abutment against the bearing surface 404 mentioned above. This bearing surface 404 extends over a periphery of the bearing 221, so that the first rib 401 can be formed at any point of the base 215 of the U shape that the cover 210 takes. Advantageously, the cooperation of the notch 411 formed on the first rib 401 with the bearing surface 404 makes it possible to limit a movement of the cover 210 from the top to the bottom, that is to say a movement which makes it possible to fold this cover 210 over the fixing device 220. According to the example illustrated here, this bearing surface 404 is flat but it could also be irregular, and by example present a notch for receiving the notch formed on the first rib without departing from the context of the present invention.
Les deux deuxième nervures 402 sont quant à elles identiques et sont ménagées, respectivement, sur l’une des branches 214 de la forme de U que prend le capot 210. Selon l’exemple illustré ici, le moyen de verrouillage 400 comprend plus particulièrement quatre deuxièmes nervures 402 réparties deux à deux sur chacune des branches 214 du capot 210. Toutes ces deuxièmes nervures 402 sont identiques et la description qui va être donnée pour l’une d’entre elle est ainsi directement transposable aux trois autres. De façon analogue, les références portées sur l’une de ces deuxièmes nervures 402 sont également directement transposables aux trois autres. The two second ribs 402 are identical and are formed, respectively, on one of the branches 214 of the U shape that takes the cover 210. According to the example illustrated here, the locking means 400 more particularly comprises four second ribs 402 distributed two by two on each of the branches 214 of the cover 210. All these second ribs 402 are identical and the description which will be given for one of them is thus directly transposable to the other three. Similarly, the references carried on one of these second ribs 402 can also be directly transposed to the other three.
Ces deuxièmes nervures 402 présentent au moins un bord inférieur 412 chanfreiné, c’est-à-dire qu’un bord de chacune de ces nervures 402 tourné vers le dispositif de fixation 220 lorsque le capot 210 est dans sa position ouverte PO présente un chanfrein. Chaque nervure 402 présente en outre au moins un bord supérieur 422 tourné vers la paroi de fond 213 du capot 210. Au moins deux ergots 403 sont par ailleurs ménagés sur le dispositif de fixation 220, par exemple à proximité du palier 221. On entend ici par « à proximité du palier 221 » le fait que chaque ergot 403 est ménagé plus près du palier 221 que de l’arbre 222 destiné à recevoir le bras d’entrainement. Chacun de ces ergots 403 comprend au moins une paroi inclinée 413 et au moins une paroi horizontale 423 qui s’étend majoritairement dans un plan dans lequel s’inscrivent l’axe longitudinal L et l’axe transversal T du trièdre illustré. Plus particulièrement, cette paroi horizontale 423 s’étend dans le même plan longitudinal et transversal que la face inférieure 228 du palier 221 et que la paroi inférieure 225 du dispositif de fixation 220. Ainsi, lorsque le capot 210 est rabattu depuis sa position ouverte PO vers sa position fermée PF, les chanfreins des bords inférieurs 412 des deuxième nervures 402 glissent contre la paroi inclinée 413 de l’un des ergots 403, puis le bord supérieur 422 de la deuxième nervure 402 concernée vient en butée contre la paroi horizontale 423 de l’ergot 403 en question. Selon l’exemple illustré, deux deuxièmes nervures 402 viennent en butée contre chaque ergot 403. On comprend que la coopération des bords supérieurs 422 des deuxièmes nervures 402 avec la paroi horizontale 423 des ergots 403 permet d’empêcher que le capot 210 ne s’ouvre intempestivement, c’est-à-dire ne passe de sa position fermée PF à sa position ouverte PO. Ainsi, les première et deuxièmes nervures 401, 402, les ergots 403 et la surface d’appui 404 forment, conjointement, le moyen de verrouillage 400 de la position fermée PF du capot 210. These second ribs 402 have at least one chamfered lower edge 412, that is to say that one edge of each of these ribs 402 turned towards the fixing device 220 when the cover 210 is in its open position PO has a chamfer . Each rib 402 also has at least one upper edge 422 facing the bottom wall 213 of the cover 210. At least two lugs 403 are also provided on the fixing device 220, for example near the bearing 221. Here we mean by “near the bearing 221” the fact that each lug 403 is formed closer to the bearing 221 than to the shaft 222 intended to receive the drive arm. Each of these pins 403 comprises at least one inclined wall 413 and at least one horizontal wall 423 which extends mainly in a plane in which the longitudinal axis L and the transverse axis T of the trihedron illustrated. More particularly, this horizontal wall 423 extends in the same longitudinal and transverse plane as the lower face 228 of the bearing 221 and that the lower wall 225 of the fixing device 220. Thus, when the cover 210 is folded down from its open position PO towards its closed position PF, the chamfers of the lower edges 412 of the second ribs 402 slide against the inclined wall 413 of one of the lugs 403, then the upper edge 422 of the second rib 402 concerned comes into abutment against the horizontal wall 423 of the ergot 403 in question. According to the example illustrated, two second ribs 402 abut against each lug 403. It is understood that the cooperation of the upper edges 422 of the second ribs 402 with the horizontal wall 423 lugs 403 makes it possible to prevent the cover 210 from opening unexpectedly, that is to say from passing from its closed position PF to its open position PO. Thus, the first and second ribs 401, 402, the lugs 403 and the bearing surface 404 form, jointly, the locking means 400 of the closed position PF of the cover 210.
Selon l’invention, le dispositif de verrouillage de la position ouverte PO du capot 210 comprend au moins un premier élément et au moins un deuxième élément répartis entre le capot 210 et le dispositif de fixation 220. Selon les exemples illustrés ici, le premier élément de ce dispositif de verrouillage est agencé sur le dispositif de fixation 220 et le deuxième élément de ce dispositif de verrouillage est quant à lui agencé sur le capot 210. Il est entendu qu’il ne s’agit que d’un exemple de réalisation et qu’on pourra prévoir que le premier élément soit ménagé sur le capot et le deuxième élément sur le dispositif de fixation sans sortir du contexte de la présente invention. According to the invention, the device for locking the open position PO of the cover 210 comprises at least a first element and at least a second element distributed between the cover 210 and the fixing device 220. According to the examples illustrated here, the first element of this locking device is arranged on the fixing device 220 and the second element of this locking device is itself arranged on the cover 210. It is understood that this is only an exemplary embodiment and that the first element may be provided on the cover and the second element on the fixing device without departing from the context of the present invention.
Tel que précédemment évoqué, ces premier et deuxième éléments sont en outre agencés au voisinage de la liaison pivot 600 ménagée entre le capot 210 et le dispositif de fixation 220. Selon l’invention, cette liaison pivot 600 comprend au moins un toron reçu dans au moins un alésage. Selon les exemples illustrés ici, la liaison pivot 600 comprend deux torons ménagés sur le capot 210 et deux alésages ménagés dans le dispositif de fixation 220, chaque toron étant reçu dans l’un de ces alésages. Tel que cela sera plus amplement détaillé ci-après, le premier élément du dispositif de verrouillage de la position ouverte PO du capot 210 est ainsi ménagé au voisinage d’au moins l’un des alésages et le deuxième élément de ce dispositif de verrouillage de la position ouverte PO du capot 210 est quant à lui ménagé au voisinage d’au moins l’un des torons ménagés sur ce capot 210. Ainsi, selon les exemples illustrés ici, le premier élément du dispositif de verrouillage de la position ouverte PO du capot 210 est ménagé sur le dispositif de fixation 220 et le deuxième élément de ce dispositif de verrouillage de la position ouverte PO du capot 210 est ménagé sur ce capot 210. Selon un exemple non illustré ici, on pourra prévoir que les alésages et le premier élément du dispositif de verrouillage de la position ouverte du capot soient ménagés sur le capot et que les torons et le deuxième élément du dispositif de verrouillage soient ménagés sur le dispositif de fixation. As previously mentioned, these first and second elements are also arranged in the vicinity of the pivot link 600 formed between the cover 210 and the fixing device 220. According to the invention, this pivot link 600 comprises at least one strand received in at minus a bore. According to the examples illustrated here, the pivot link 600 comprises two strands formed on the cover 210 and two bores provided in the fixing device 220, each strand being received in one of these bores. As will be explained in more detail below, the first element of the device for locking the open position PO of the cover 210 is thus formed in the vicinity of at least one of the bores and the second element of this device for locking the the open position PO of the cover 210 is itself formed in the vicinity of at least one of the strands formed on this cover 210. Thus, according to the examples illustrated here, the first element of the device for locking the open position PO of the cover 210 is provided on the fixing device 220 and the second element of this device for locking the open position PO of cover 210 is provided on this cover 210. According to an example not illustrated here, provision may be made for the bores and the first element of the locking device for the open position of the cover are provided on the cover and the strands and the second element of the locking device are provided on the device itif of fixation.
En référence aux figures 4 à 6, nous allons maintenant décrire l’ensemble de connexion 200 selon un premier exemple de réalisation de la présente invention et, en référence aux figures 7 à 9, nous décrirons l’ensemble de connexion 200 selon un deuxième exemple de réalisation de la présente invention. With reference to FIGS. 4 to 6, we will now describe the connection assembly 200 according to a first embodiment of the present invention and, with reference to FIGS. 7 to 9, we will describe the connection assembly 200 according to a second example of the present invention.
La figure 4 illustre ainsi, en perspective, le dispositif de fixation 220 selon le premier exemple de réalisation et la figure 5 illustre quant à elle le capot 210 réalisé selon ce premier exemple de réalisation. Plus précisément, ces figures 4 et 5 rendent particulièrement visible, respectivement, un alésage 240 de la liaison pivot ménagée entre le dispositif de fixation 220 et le capot 210 et un toron 230 de cette liaison pivot. FIG. 4 thus illustrates, in perspective, the fixing device 220 according to the first exemplary embodiment and FIG. 5 illustrates, for its part, the cover 210 produced according to this first exemplary embodiment. More specifically, these Figures 4 and 5 make particularly visible, respectively, a bore 240 of the pivot connection formed between the fixing device 220 and the cover 210 and a strand 230 of this pivot connection.
Tel qu’illustré sur la figure 4, au moins un des alésages 240 est ménagé dans l’une des parois latérales 223 du dispositif de fixation 220, en regard de l’arbre 222 sur lequel le bras d’entrainement est destiné à être monté. Selon une configuration particulière de la présente invention, les deux alésages 240 peuvent communiquer par l’intermédiaire de cet arbre 222. En d’autres termes, selon cette configuration particulière, cet arbre 222 est creux et débouche sur chacune des parois latérales 223 du dispositif de fixation 220. As illustrated in FIG. 4, at least one of the bores 240 is formed in one of the side walls 223 of the fixing device 220, opposite the shaft 222 on which the drive arm is intended to be mounted . According to a particular configuration of the present invention, the two bores 240 can communicate via this shaft 222. In other words, according to this particular configuration, this shaft 222 is hollow and opens onto each of the side walls 223 of the device fixing 220.
En outre, chaque paroi latérale 223 qui porte l’un des alésages 240 présente au moins deux saignées 242 ménagées obliquement depuis un bord supérieur 226 de la paroi latérale 223 concernée, c’est-à-dire un bord de cette paroi latérale 223 tourné vers la paroi de fond du capot lorsque celui-ci est monté sur le dispositif de fixation 220 et qu’il est dans sa position fermée, jusqu’à une ouverture 243 de l’alésage 240 par laquelle le toron concerné peut être inséré dans cet alésage 240. On comprend que ces saignées 242 facilitent l’introduction du toron 230 dans l’alésage 240 concerné, notamment en formant un guide à l’introduction de ce toron 230 dans l’alésage 240. In addition, each side wall 223 which carries one of the bores 240 has at least two grooves 242 formed obliquely from an upper edge 226 of the side wall 223 concerned, that is to say an edge of this side wall 223 turned. towards the bottom wall of the hood when the latter is mounted on the fixing device 220 and when it is in its closed position, up to an opening 243 of the bore 240 by which the strand concerned can be inserted into this bore 240. It is understood that these grooves 242 facilitate the introduction of the strand 230 into the bore 240 concerned, in particular by forming a guide for the introduction of this strand 230 into the bore 240.
Un dégagement de matière 120 est en outre réalisé sur chacune des parois latérales 223 du dispositif de fixation 220, ces dégagements de matière 120 étant configurés pour recevoir une extrémité terminale du bras d’entrainement du système d’essuyage équipé de l’ensemble de connexion 200 selon l’invention. Autrement dit, ces dégagements de matière 120 permettent, avec l’arbre 222 décrit ci-dessus, de fixer le bras d’entrainement sur le dispositif de fixation 220. Ces dégagements de matière 120 sont ménagés sur une face externe de chaque paroi latérale 223, c’est-à-dire une face de chaque paroi latérale tournée vers les branches du capot lorsque celui-ci est monté sur le dispositif de fixation 220 et qu’il est dans sa position fermée. Un seul de ces dégagements de matière 120 est ainsi visible sur la figure 4. Un trou 121 est en outre ménagé dans chacun de ces dégagements de matière 120 afin de permettre l’insertion d’un élément de fixation du bras d’entrainement sur le dispositif de fixation 220. Par exemple cet élément de fixation du bras d’entrainement peut être configuré pour autoriser au moins un degré de liberté du bras d’entrainement par rapport au dispositif de fixation 220. Tel que cela sera plus amplement détaillé ci-après, une portion 510 d’au moins l’une des parois latérales 223 située entre l’alésage 240 ménagé dans la paroi latérale 223 concernée et le dégagement de matière 120 forme, selon le premier exemple de réalisation, le premier élément du dispositif de verrouillage. A material clearance 120 is furthermore produced on each of the side walls 223 of the fixing device 220, these material clearances 120 being configured to receive a terminal end of the drive arm of the wiping system equipped with the connection assembly 200 according to the invention. In other words, these material clearances 120 allow, with the shaft 222 described above, to fix the drive arm on the fixing device 220. These material clearances 120 are provided on an external face of each side wall 223 , that is to say one face of each side wall facing the branches of the cover when the latter is mounted on the fixing device 220 and that it is in its closed position. Only one of these material clearances 120 is thus visible in FIG. 4. A hole 121 is further provided in each of these material clearances 120 in order to allow the insertion of a fastening element of the drive arm on the fixing device 220. For example, this fixing element of the driving arm can be configured to allow at least one degree of freedom of the driving arm relative to the fixing device 220. As will be described in more detail below , a portion 510 of at least one of the side walls 223 situated between the bore 240 formed in the side wall 223 concerned and the release of material 120 forms, according to the first embodiment, the first element of the locking device .
La figure 5 rend quant à elle visible l’un des torons 230 de la liaison pivot, ce toron 230 étant ménagé sur le capot 210. Plus particulièrement ce toron 230 est ménagé sur l’une des branches 214 du capot 210 et s’étend vers l’autre branche 214 du capot 210, dans le volume interne de ce capot 210. Vu depuis ce volume interne du capot 210, le toron 230 présente une forme en C, c’est-à-dire qu’il comprend au moins deux pattes 231 - une seule de ces pattes 231 étant référencée sur la figure 5 - reliées entre elles par un pont de matière 232. On remarque également que les extrémités 236 de chacune des pattes 231 de cette forme en C présentent un chanfrein. Avantageusement, ces chanfreins facilitent l’insertion du toron dans l’alésage concerné. L’autre toron, non visible sur cette figure 5, est identique à ce qui vient d’être décrit. Figure 5 makes visible one of the strands 230 of the pivot connection, this strand 230 being formed on the cover 210. More particularly this strand 230 is formed on one of the branches 214 of the cover 210 and extends towards the other branch 214 of the cover 210, in the internal volume of this cover 210. Seen from this internal volume of the cover 210, the strand 230 has a C shape, that is to say that it comprises at least two tabs 231 - only one of these tabs 231 being referenced in FIG. 5 - connected together by a bridge of material 232. It is also noted that the ends 236 of each of the tabs 231 of this C-shaped have a chamfer. Advantageously, these chamfers facilitate the insertion of the strand into the bore concerned. The other strand, not visible in this figure 5, is identical to what has just been described.
En outre, le toron 230 s’étend depuis un socle 235 issu de matière avec la branche 214 du capot 210 porteuse de ce toron 230. Autrement dit, ce socle 235 et la branche 214 concernée forment un unique ensemble qui ne peut être séparé sans entraîner la détérioration de l’un ou de l’autre. Tel qu’illustré, ce socle 235 présente une surépaisseur 237. Cette surépaisseur 237 s’étend parallèlement à un plan dans lequel s’inscrit majoritairement le socle 235, depuis le toron 230, et plus particulièrement depuis l’une des pattes 231 de ce toron 230, et jusqu’à un bord avant 238 du socle 235. On entend par « bord avant » un bord du socle 235 tourné vers le bras d’entrainement lorsque l’ensemble de connexion est fixé sur ce bras d’entrainement et que le capot est dans sa position fermée. Autrement dit, ce bord avant 238 est, selon le premier exemple de réalisation illustré sur la figure 5, le bord du socle 235 le plus éloigné du toron 230. La surépaisseur 237 est en outre ménagée à une distance non nulle d’un bord inférieur 239 du socle 235, c’est-à- dire un bord de ce socle 235 tourné à l’opposé de la paroi de fond 213 du capot 210. Tel que cela sera plus amplement détaillé ci-après, cette distance non nulle ménagée entre le bord inférieur 239 du socle 235 et la surépaisseur 237 permet au capot 210 de pivoter de sa position fermée PF vers sa position ouverte PO, ou de sa position ouverte PO vers sa position fermée PF. In addition, the strand 230 extends from a base 235 made in one piece with the branch 214 of the cover 210 carrying this strand 230. In other words, this base 235 and the branch 214 concerned form a single assembly which cannot be separated without lead to the deterioration of one or the other. As illustrated, this base 235 has an extra thickness 237. This extra thickness 237 extends parallel to a plane in which is mainly registered on the base 235, from the strand 230, and more particularly from one of the legs 231 of this strand 230, and up to a front edge 238 of the base 235. The term "front edge" means an edge of the base 235 facing the drive arm when the connection assembly is fixed to this drive arm and the cover is in its closed position. In other words, this front edge 238 is, according to the first embodiment illustrated in FIG. 5, the edge of the base 235 furthest from the strand 230. The additional thickness 237 is furthermore provided at a non-zero distance from a lower edge 239 of the base 235, that is to say an edge of this base 235 turned away from the bottom wall 213 of the cover 210. As will be described in more detail below, this non-zero distance provided between the lower edge 239 of the base 235 and the extra thickness 237 allows the cover 210 to pivot from its closed position PF to its open position PO, or from its open position PO to its closed position PF.
Tel que précédemment évoqué, le deuxième élément du dispositif de verrouillage de la position ouverte du capot 210 est ménagé au voisinage d’au moins l’un des torons 230. Selon le premier exemple de réalisation illustré ici, ce deuxième élément du dispositif de verrouillage de la position ouverte du capot 210 est réalisé par la surépaisseur 237. As previously mentioned, the second element of the device for locking the open position of the cover 210 is formed in the vicinity of at least one of the strands 230. According to the first embodiment illustrated here, this second element of the locking device of the open position of the cover 210 is produced by the extra thickness 237.
Selon l’exemple illustré ici, le dispositif de verrouillage de la position ouverte du capot 210 comprend un unique deuxième élément, de sorte que l’autre toron, c’est-à-dire le toron ménagé sur l’autre branche 214 du capot 210 et qui n’est pas visible sur la figure 5, s’étend directement depuis cette autre branche 214. En d’autres termes, cette autre branche est au moins dépourvue de surépaisseur. Selon l’invention, cet autre toron peut émerger directement de la branche du capot concernée ou d’un socle ménagé sur cette branche. Alternativement, on pourra prévoir que le dispositif de verrouillage comprenne deux deuxièmes éléments, chacun de ces deuxièmes éléments étant alors ménagé au voisinage de l’un des torons tel que cela vient d’être décrit. According to the example illustrated here, the device for locking the open position of the cover 210 comprises a single second element, so that the other strand, that is to say the strand formed on the other branch 214 of the cover 210 and which is not visible in FIG. 5, extends directly from this other branch 214. In other words, this other branch is at least devoid of additional thickness. According to the invention, this other strand can emerge directly from the branch of the hood concerned or from a base formed on this branch. Alternatively, provision may be made for the locking device to comprise two second elements, each of these second elements then being formed in the vicinity of one of the strands as has just been described.
La figure 6 illustre une vue partielle, selon une coupe transversale, de l’ensemble de connexion 200 selon le premier exemple de réalisation de la présente invention dans lequel le capot 210 est dans sa position ouverte PO, cette coupe passant par la liaison pivot 600 ménagée entre le dispositif de fixation 220 et le capot 210. FIG. 6 illustrates a partial view, in a cross section, of the connection assembly 200 according to the first embodiment of the present invention in which the cover 210 is in its open position PO, this section passing through the pivot link 600 formed between the fixing device 220 and the cover 210.
Tel que précédemment évoqué, le premier élément du dispositif de verrouillage 500 est formé, selon le premier exemple de réalisation illustré ici, par la portion 510 de la paroi latérale 223 située entre l’alésage 240 ménagé dans cette paroi latérale 223 et qui reçoit le toron 230 au voisinage duquel est ménagé le deuxième élément de ce dispositif de verrouillage 500 et le dégagement de matière 120 destiné à recevoir le bras d’entrainement. Autrement dit, la surépaisseur 237 ménagée sur le socle 235 du toron 230 concerné vient en frottement contre cette portion 510 de la paroi latérale 223 en question, ce frottement assurant le verrouillage de la position ouverte PO du capot 210. On entend par « frottement » le fait que la surépaisseur 237 soit en contact avec la portion 510 de la paroi latérale 223 et que ce contact génère un effort de maintien. En d’autres termes, une zone de frottement 700 est crée entre la portion de la paroi latérale 223 et la surépaisseur 237 ménagée sur le socle 235 lorsque le capot 210 est dans sa position ouverte PO, c’est-à-dire une zone dans laquelle le capot 210, et plus particulièrement la branche 214 de ce capot 120 porteuse de la surépaisseur 237, subit une déformation qui permet de verrouiller la position ouverte PO du capot 210. On comprend que cette déformation se traduit en un éloignement de la branche 214 du capot 210 concernée par rapport au dispositif de fixation 220, et plus particulièrement par rapport à la paroi latérale 223 concernée de ce dispositif de fixation 220. Cette déformation élastique des parois latérales 223 génère une force normale au niveau de la zone de frottement 700 et donc la friction entre les premier et deuxième dispositifs de verrouillage 500, ce qui sert à bloquer le capot 210 dans la position ouverte. On comprend alors que le pivotement du capot 210 depuis sa position fermée vers sa position ouverte PO est facilité grâce à la distance non-nulle ménagée entre la surépaisseur 237 et le bord inférieur 239 du socle 235 et que le verrouillage de cette position ouverte PO du capot 210 est réalisé lorsque cette surépaisseur 237 vient au contact de la portion 510 de la paroi latérale 223 située entre l’alésage 240 et le dégagement de matière 120. On comprend en outre que ce verrouillage de la position ouverte du capot 210 est réversible et que l’exercice d’une force entraînant le pivotement du capot 210 de sa position ouverte vers sa position fermée permet de s’affranchir de ce verrouillage et de passer ce dernier dans sa position fermée dans laquelle la zone de fixation est protégée par ce capot, c’est-à-dire que cette zone de fixation est inaccessible. As previously mentioned, the first element of the locking device 500 is formed, according to the first embodiment illustrated here, by the portion 510 of the side wall 223 located between the bore 240 formed in this side wall 223 and which receives the strand 230 in the vicinity of which is formed the second element of this locking device 500 and the release of material 120 intended to receive the drive arm. In other words, the additional thickness 237 formed on the base 235 of the strand 230 concerned comes into friction against this portion 510 of the side wall 223 in question, this friction ensuring the locking of the open position PO of the cover 210. The term “friction” is understood the fact that the extra thickness 237 is in contact with the portion 510 of the side wall 223 and that this contact generates a holding force. In other words, a friction zone 700 is created between the portion of the side wall 223 and the extra thickness 237 formed on the base 235 when the cover 210 is in its open position PO, that is to say a zone in which the cover 210, and more particularly the branch 214 of this cover 120 carrying the additional thickness 237, undergoes a deformation which makes it possible to lock the open position PO of the cover 210. It is understood that this deformation results in a distancing of the branch 214 of the cover 210 concerned with respect to the fixing device 220, and more particularly with respect to the side wall 223 concerned with this fixing device 220. This elastic deformation of the side walls 223 generates a normal force at the level of the friction zone 700 and therefore the friction between the first and second locking devices 500, which serves to block the cover 210 in the open position. It will then be understood that the pivoting of the cover 210 from its closed position to its open position PO is facilitated by the non-zero distance provided between the additional thickness 237 and the lower edge 239 of the base 235 and that the locking of this open position PO of the cover 210 is produced when this additional thickness 237 comes into contact with the portion 510 of the side wall 223 located between the bore 240 and the material release 120. It is further understood that this locking of the open position of cover 210 is reversible and that the exercise of a force causing the pivoting of the cover 210 from its open position to its closed position allows to overcome this locking and to pass the latter in its closed position in which the fixing zone is protected by this cover, that is to say that this fixing zone is inaccessible.
On remarque en outre sur cette figure 6 que le socle 235 est ajouré, c’est-à- dire qu’une lumière 135 est ménagée entre ce socle 235 et la branche 214 du capot 210 de laquelle il émerge, de sorte à ne pas alourdir inutilement l’ensemble de connexion selon l’invention. It is further noted in this FIG. 6 that the base 235 is perforated, that is to say that a light 135 is formed between this base 235 and the branch 214 of the cover 210 from which it emerges, so as not to unnecessarily weigh down the connection assembly according to the invention.
La figure 7 illustre le dispositif de fixation 220 de l’ensemble de connexion réalisé selon le deuxième exemple de réalisation de la présente invention. Ce dispositif de fixation 220 réalisé selon le deuxième exemple de réalisation diffère du dispositif de fixation 220 réalisé selon le premier exemple de réalisation en ce qu’il comprend en outre un plot 130. Tel que représenté, ce plot 130 est ménagé sur la portion 510 de la paroi latérale 223 située entre l’alésage 240 et le dégagement de matière 120. Ce plot 130 émerge de la paroi latérale 223 concernée et présente une forme tétraédrique, ou sensiblement tétraédrique. On entend ici par « émerge de la paroi latérale 223 » le fait que ce plot 130 et la paroi latérale 223 porteuse de ce plot 130 forment un ensemble monobloc, c’est-à-dire un ensemble qui ne peut être séparé sans entraîner la détérioration du plot 130 ou de la paroi latérale 223. FIG. 7 illustrates the fixing device 220 of the connection assembly produced according to the second exemplary embodiment of the present invention. This fixing device 220 produced according to the second exemplary embodiment differs from the fixing device 220 produced according to the first exemplary embodiment in that it further comprises a stud 130. As shown, this stud 130 is formed on the portion 510 from the side wall 223 located between the bore 240 and the release of material 120. This stud 130 emerges from the side wall 223 concerned and has a tetrahedral, or substantially tetrahedral shape. The expression “emerges from the side wall 223” is understood here to mean that this stud 130 and the side wall 223 carrying this stud 130 form a one-piece assembly, that is to say an assembly which cannot be separated without causing the deterioration of the stud 130 or the side wall 223.
Tel que cela sera plus amplement détaillé ci-après, au moins une portion de ce plot 130, et particulièrement une face supérieure 131 de ce plot 130, forme, selon le deuxième exemple de réalisation de la présente invention, le premier élément du dispositif de verrouillage de la position ouverte du capot. On entend par « face supérieure 131 du plot 130 », une face de ce plot 130 la plus proche de l’alésage 240 ménagé dans la paroi latérale 223 du dispositif de fixation 220 concernée. Par ailleurs, le dispositif de fixation 220 selon le deuxième exemple de réalisation est en tout point identique au dispositif de fixation 220 selon le premier exemple de réalisation et la description qui en est faite en référence à la figure 4 s’applique mutatis mutandis à la figure 7. As will be described in more detail below, at least a portion of this stud 130, and particularly an upper face 131 of this stud 130, forms, according to the second embodiment of the present invention, the first element of the device. locking the hood open position. The term "upper face 131 of the stud 130" means a face of this stud 130 closest to the bore 240 formed in the side wall 223 of the fixing device 220 concerned. Furthermore, the fixing device 220 according to the second exemplary embodiment is identical in all respects to the fixing device 220 according to the first exemplary embodiment and the description which is made with reference to FIG. 4 applies mutatis mutandis to the figure 7.
La figure 8 illustre quant à elle le capot 210 de l’ensemble de connexion selon le deuxième exemple de réalisation de la présente invention. Ce capot 210 est similaire à ce qui a été décrit précédemment en référence à la figure 5, notamment en ce qu’au moins l’un des torons 230 est issu de matière avec un socle 235 et en ce que l’autre toron 230 s’étend quant à lui directement depuis la branche 214 du capot 210 concernée. De façon analogue à ce qui a été précédemment décrit, on pourra prévoir que les deux torons soient identiques sans sortir du contexte de la présente invention. FIG. 8 illustrates the cover 210 of the connection assembly according to the second embodiment of the present invention. This cover 210 is similar to what has been described above with reference to FIG. 5, in particular in that at least one of the strands 230 is made from a material with a base 235 and in that the other strand 230 extends as regards him directly from the branch 214 of the cover 210 concerned. Similarly to what has been described above, provision may be made for the two strands to be identical without departing from the context of the present invention.
En revanche, ce capot 210 selon le deuxième exemple de réalisation diffère du capot réalisé selon le premier exemple de réalisation en ce que le socle 235 qui porte au moins l’un des torons 230 est dépourvu de surépaisseur. Ainsi, selon ce deuxième exemple de réalisation de la présente invention, le deuxième élément du dispositif de verrouillage de la position ouverte PO du capot 210 est formé par le bord avant 238 du socle 235, c’est-à-dire le bord de ce socle 235 tourné vers le bras d’entrainement lorsque celui-ci est fixé sur l’ensemble de connexion et que le capot 210 est dans sa position fermée. On the other hand, this cover 210 according to the second embodiment differs from the cover produced according to the first embodiment in that the base 235 which carries at least one of the strands 230 is devoid of excess thickness. Thus, according to this second embodiment of the present invention, the second element of the device for locking the open position PO of the cover 210 is formed by the front edge 238 of the base 235, that is to say the edge of this base 235 facing the drive arm when the latter is fixed to the connection assembly and the cover 210 is in its closed position.
La figure 9 illustre enfin une vue selon une coupe transversale de l’ensemble de connexion 200 selon le deuxième exemple de réalisation de la présente invention dans lequel le capot 210 est dans sa position ouverte PO, cette coupe passant par la liaison pivot 600 ménagée entre le dispositif de fixation 220 et le capot 210. FIG. 9 finally illustrates a view according to a transverse section of the connection assembly 200 according to the second embodiment of the present invention in which the cover 210 is in its open position PO, this section passing through the pivot link 600 formed between the fixing device 220 and the cover 210.
Tel qu’évoqué ci-dessus, le premier élément du dispositif de verrouillage 500 est formé par la face supérieure 131 du plot 130 ménagé sur la portion 510 de la paroi latérale 223 située entre l’alésage 240 et le dégagement de matière 120, et le deuxième élément de ce dispositif de verrouillage 500 de la position ouverte PO du capot 210 est quant à lui formé par le bord avant 238 du socle 235. De façon analogue à ce qui a été décrit pour le premier exemple de réalisation, on comprend que c’est le frottement entre ce bord avant 238 et la face supérieure 131 du plot 130 qui permet ici le verrouillage de la position ouverte PO du capot 210. Autrement dit, une zone de contact 701 est crée entre la face supérieure 131 du plot 130 et le bord avant 238 du socle 235 lorsque le capot 210 est dans sa position ouverte PO. Tel que précédemment évoqué, on entend ici par « frottement » le fait que le bord avant 238 du socle 235 est en contact avec la face supérieure 131 du plot 130 et que ce contact génère un effort de maintien. Selon ce deuxième exemple de réalisation de la présente invention, ce frottement génère plus particulièrement un appui radial du toron 230 dans son alésage 240 qui assure le maintien de la position ouverte PO du capot 210. Selon un exemple particulier illustré sur cette figure 9, le premier élément du dispositif de verrouillage 500 est plus particulièrement formé par une arête chanfreinée qui délimite la face supérieure 131 du plot 130. Avantageusement, cette arête chanfreinée facilite le frottement entre le bord avant 238 et la face supérieure 131 du plot 130 de sorte à faciliter le verrouillage de la position ouverte PO du capot 210. Alternativement, on pourra prévoir que le bord avant du socle formant le deuxième élément du dispositif de verrouillage de la position ouverte du capot soit également chanfreiné. Selon une autre alternative, seul le bord avant du socle formant le deuxième élément du dispositif de verrouillage présente un chanfrein. As mentioned above, the first element of the locking device 500 is formed by the upper face 131 of the stud 130 formed on the portion 510 of the side wall 223 located between the bore 240 and the release of material 120, and the second element of this locking device 500 of the open position PO of the cover 210 is in turn formed by the front edge 238 of the base 235. In a similar manner to what has been described for the first embodiment, it is understood that it is the friction between this front edge 238 and the upper face 131 of the stud 130 which here allows the locking of the open position PO of the cover 210. In other words, a contact area 701 is created between the upper face 131 of the stud 130 and the front edge 238 of the base 235 when the cover 210 is in its open position PO. As previously mentioned, the term “friction” here means that the front edge 238 of the base 235 is in contact with the upper face 131 of the stud 130 and that this contact generates a holding force. According to this second embodiment of the present invention, this friction generates more particularly a radial support of the strand 230 in its bore 240 which ensures the maintenance of the open position PO of the cover 210. According to a particular example illustrated in this FIG. 9, the first element of the locking device 500 is more particularly formed by a chamfered edge which delimits the upper face 131 of the stud 130. Advantageously, this chamfered edge facilitates the friction between the front edge 238 and the upper face 131 of the stud 130 so as to facilitate the locking of the open position PO of the cover 210. Alternatively, provision may be made for the front edge of the base forming the second element of the device for locking the open position of the cover to also be chamfered. According to another alternative, only the front edge of the base forming the second element of the locking device has a chamfer.
Tel que précédemment, on remarque qu’une lumière 135 est ménagée entre le socle 235 et la branche 214 de laquelle il est issu de sorte à ne pas alourdir inutilement l’ensemble de connexion 200 selon l’invention. As previously, it is noted that a light 135 is formed between the base 235 and the branch 214 from which it comes so as not to unnecessarily burden the connection assembly 200 according to the invention.
La présente invention propose ainsi un moyen simple et peu coûteux permettant de verrouiller notamment la position ouverte d’un capot d’un ensemble de connexion d’un système d’essuyage afin de faciliter l’accès à une zone de fixation d’un dispositif de fixation de cet ensemble de connexion sur un arbre moteur d’un véhicule, et ainsi de faciliter la mise en place de moyens de fixation permettant de solidariser le dispositif de fixation sur l’arbre moteur. The present invention thus provides a simple and inexpensive means for locking in particular the open position of a cover of a connection assembly of a wiping system in order to facilitate access to a fixing zone of a device. fixing this connection assembly on a motor shaft of a vehicle, and thus facilitate the establishment of fixing means for securing the fixing device on the motor shaft.
La présente invention ne saurait toutefois se limiter aux moyens et configurations décrits et illustrés ici et elle s’étend également à tout moyen ou configuration équivalents et à toute combinaison techniquement opérante de tels moyens. En particulier, la forme et la disposition du premier élément et du deuxième élément du dispositif de verrouillage de la position ouverte du capot peuvent être modifiées sans nuire à l’invention dans la mesure où elles remplissent les fonctionnalités décrites dans le présent document. The present invention cannot however be limited to the means and configurations described and illustrated here and it also extends to any equivalent means or configuration and to any technically effective combination of such means. In particular, the shape and arrangement of the first element and of the second element of the device for locking the open position of the cover can be modified without harming the invention insofar as they fulfill the functions described in this document.
