Description

SYSTEME DE CHARNIERES POUR PORTE DE COFFRE DE VEHICULE AUTOMOBILE COMPORTANT UN BRAS ARTICULE ET UN BRAS COULISSANTHINGE SYSTEM FOR A MOTOR VEHICLE TRUNK DOOR HAVING AN ARTICULATED ARM AND A SLIDING ARM

L'invention concerne une porte de coffre de véhicule automobile munie d'un nouveau système de charnières comportant un bras articulé et un bras coulissant.The invention relates to a motor vehicle trunk door provided with a new hinge system comprising an articulated arm and a sliding arm.

Les portes de coffre d'automobiles sont, pour la plupart, dotées de charnières articulées autour d'axes sensiblement horizontaux et s'ouvrent par un mouvement de rotation du bas vers le haut.Most car trunk doors have hinges hinged about substantially horizontal axes and open by a rotation movement from the bottom up.

On connaît également des véhicules, en général utilitaires, dotés d'une porte coulissante, la porte étant guidée par une paire de rails inférieur et supérieur qui coopèrent chacun avec des galets montés sur un bras lui-même articulé sur la porte (EP-A-401081 ) .Also known are vehicles, in general utility vehicles, equipped with a sliding door, the door being guided by a pair of lower and upper rails which each cooperate with rollers mounted on an arm itself articulated on the door (EP-A -401081).

L'invention concerne un nouveau système de charnières pour porte de coffre de véhicule automobile qui permet à la porte de coffre de passer de la position fermée à une position ouverte dans laquelle elle vient se placer le long d'une aile arrière du véhicule.The invention relates to a new hinge system for a trunk door of a motor vehicle which allows the trunk door to pass from the closed position to an open position in which it is placed along a rear wing of the vehicle.

Plus particulièrement, l'invention concerne une porte de coffre de véhicule automobile articulée à une des extrémités d'un premier bras monté pivotant, à son autre extrémité, autour d'un axe latéral vertical solidaire du châssis, caractérisée en ce qu'elle se déplace d'une position de fermeture vers une position d'ouverture, sensiblement perpendiculaire à ladite position de fermeture, par l'intermédiaire du premier bras présentant une forme recourbée, et d'un deuxième bras dont l'une de ses extrémités est assujettie à ladite porte et l'autre extrémité est montée pivotante sur un coulisseau (11) monté dans un rail de guidage.More particularly, the invention relates to a trunk door of a motor vehicle articulated at one end of a first arm pivotally mounted, at its other end, around a vertical lateral axis secured to the chassis, characterized in that it is moves from a closed position to an open position, substantially perpendicular to said closed position, by means of the first arm having a curved shape, and of a second arm of which one of its ends is subject to said door and the other end is pivotally mounted on a slide (11) mounted in a guide rail.

Selon un mode de réalisation, le rail présente une forme coudée avec une première portion orientée obliquement par rapport au plan de symétrie dα véhicule et s 'étendant d'un point intérieur du plancher du véhicule jusqu'à un point situe vers le milieu de l'arriére du véhicule, et une deuxième portion s ' étendant dudit point milieu arrière, sensiblement parallèlement au bord inférieur de l'embrasure de la porte de coffre, et en direction du côte ou est monte ledit axe latéral vertical .According to one embodiment, the rail has a bent shape with a first oriented portion obliquely to the plane of symmetry of the vehicle and extending from an interior point of the vehicle floor to a point located towards the middle of the rear of the vehicle, and a second portion extending from said rear midpoint, substantially parallel to the lower edge of the opening of the trunk door, and in the direction of the coast where the said vertical lateral axis rises.

Le premier bras a une forme recourbée telle que, lorsque ce bras pivote autour de son axe latéral vertical, sa partie concave vient épouser sensiblement l'aile arrière de la carrosserie du véhicule, dans la position correspondant a l'ouverture maximale de la porte . Le rôle de ce bras est de mouvoir la porte de coffre de sa position de fermeture a sa position d'ouverture maximale dans laquelle la porte se trouve le long d'un des ailes arrière du véhicule. Pour cela, le bras recourbe doit pouvoir pivoter d'un angle d'au moins 180°, de préférence d'environ 190-200°.The first arm has a curved shape such that, when this arm pivots around its vertical lateral axis, its concave part substantially matches the rear wing of the vehicle body, in the position corresponding to the maximum opening of the door. The role of this arm is to move the trunk door from its closed position to its maximum open position in which the door is located along one of the rear wings of the vehicle. For this, the curved arm must be able to pivot by an angle of at least 180 °, preferably about 190-200 °.

Le rôle du deuxième bras est de contrôler la cinématique de la porte lors du pivotement du premier bras. En l'absence de ce deuxième bras, la porte, qui est articulée a l'extrémité du premier bras opposée a l'axe de pivotement de celui-ci, pourrait s'orienter de façon indésirable et venir notamment heurter l'aile arrière du véhicule .The role of the second arm is to control the kinematics of the door during the pivoting of the first arm. In the absence of this second arm, the door, which is articulated at the end of the first arm opposite the pivot axis of the latter, could orient itself in an undesirable manner and in particular strike the rear wing of the vehicle.

A cette fin, le αeuxieme bras a une longueur et le rail de guidage a une forme telles que, au cours du stade initial de l'ouverture de la porte, ils amènent la porte a se déplacer principalement dans une direction sensiblement transverse a elle-même, puis, ensuite, ils fassent tourner la porte d'environ 90° pour l'amener a se ranger le long d'une des ailes arrière du véhicule sans heurter la carrosserie du véhicule. L'ouverture et la fermeture de la porte peuvent être opérées manuellement ou bien par le moyen d'un moteur électrique assurant le pivotement du bras recourbe autour de son axe vertical latéral solidaire du châssis. La description qui va suivre faite en se référant aux dessins annexes fera bien comprendre la présente invention .To this end, the second arm has a length and the guide rail has a shape such that, during the initial stage of the opening of the door, they cause the door to move mainly in a direction substantially transverse to it. even, then, then, they rotate the door about 90 ° to bring it to line up along one of the rear wings of the vehicle without hitting the vehicle body. The opening and closing of the door can be done manually or by means of an electric motor ensuring the pivoting of the bent arm around its lateral vertical axis secured to the chassis. The following description made with reference to the accompanying drawings will make the present invention well understood.

Les figures 1, 2 et 3 sont des vues schématiques illustrant une porte de coffre dotée d'un système de charnières conforme a l'invention en position fermée, en position légèrement ouverte, et en position d'ouverture maximale, respectivement.Figures 1, 2 and 3 are schematic views illustrating a trunk door with a hinge system according to the invention in the closed position, in the slightly open position, and in the maximum open position, respectively.

Sur ces figures est représentée la partie arrière d'un véhicule automobile 1 ayant un châssis 2. Pour la clarté de la représentation le toit du véhicule et l'aménagement intérieur (sièges, plancher) ont été omis. Ce véhicule comporte une porte de coffre 3 de forme courbe qui, en position fermée, est reçue dans une embrasure 4. En ce qui concerne la carrosserie, on a juste représenté les ailes arrière 5. La porte 3 est reliée, à sa partie inférieure et, de façon articulée autour d'un axe vertical 6, à une des extrémités d'un bras recourbé 7 dont 1 ' autre extrémité est montée pivotante autour d'un axe latéral vertical 8 solidaire du châssis 2 ou d'une pièce solidaire de ce châssis. Le point d'articulation du bras 7 à la porte 3 se situe approximativement au tiers gauche de la largeur de la porte .In these figures is shown the rear part of a motor vehicle 1 having a chassis 2. For the clarity of the representation the vehicle roof and the interior fittings (seats, floor) have been omitted. This vehicle comprises a trunk door 3 of curved shape which, in the closed position, is received in a recess 4. With regard to the bodywork, the rear fenders 5 have just been shown. The door 3 is connected, at its lower part and, articulated around a vertical axis 6, at one end of a curved arm 7, the other end of which is pivotally mounted around a vertical lateral axis 8 secured to the chassis 2 or to a piece secured to this chassis. The point of articulation of the arm 7 to the door 3 is located approximately at the left third of the width of the door.

La partie inférieure de la porte 3 est également reliée, au voisinage de son bord droit, de façon fixe, à une des extrémités d'un deuxième bras 9 dont l'autre extrémité est montée pivotante autour d'un axe vertical 10 qui est lui-même porté par un coulisseau 11 susceptible de coulisser dans un rail 12 fixe au châssis du véhicule. Le coulisseau 11 peut comprendre, par exemple, un support 13 portant l'axe 10 et monté sur des galets 14 assurant le coulissement dans le rail. Le rail 12 présente une forme coudée avec une première portion 12a orientée obliquement (par exemple à environ 45°) par rapport au plan de symétrie du véhicule et qui s ' étend d'un point intérieur du plancher du véhicule jusqu'à un coude 12b situé vers le milieu de l'arrière du véhicule, et une deuxième portion 12c qui s'étend dudit coude, sensiblement parallèlement au bord inférieur de l'embrasure 4 de la porte et en direction du côté où est implanté 1 ' axe 8.The lower part of the door 3 is also connected, in the vicinity of its straight edge, in a fixed manner, to one of the ends of a second arm 9, the other end of which is pivotally mounted around a vertical axis 10 which is itself even carried by a slide 11 capable of sliding in a rail 12 fixed to the chassis of the vehicle. The slide 11 can include, for example, a support 13 carrying the axis 10 and mounted on rollers 14 ensuring the sliding in the rail. The rail 12 has a bent shape with a first portion 12a oriented obliquely (for example at about 45 °) relative to the plane of symmetry of the vehicle and which extends from an interior point of the vehicle floor to an elbow 12b located towards the middle of the rear of the vehicle, and a second portion 12c which extends from said elbow, substantially parallel to the lower edge of the doorway 4 and towards the side on which the axis 8 is located.

En position fermée, le coulisseau 11 se situe à l'extrémité de la portion 12a opposée au coude 12b, comme représenté sur la figure 1. L'ouverture de la porte s'effectue en tirant sur la poignée 15 de la serrure intégrée à la porte ce qui a pour effet, d'abord, de déverrouiller la serrure puis d'amener la porte à se déplacer, dans une première phase, dans une direction sensiblement perpendiculaire à elle- même, ce déplacement résultant du pivotement dextrorsum, du bras recourbé 7 autour de l'axe vertical 8, et du pivotement senestrorsum, de la porte autour de l'axe vertical 10 provoquée par le bras 9 dont l'extrémité opposée à la porte est assujettie à se déplacer selon un trajet déterminé par le rail 12. La figure 2 illustre une position d'ouverture pendant cette première phase. Cette première phase d'ouverture s'achève lorsque le coulisseau 11 parvient au coude 12b du rail. A partir de ce moment là, les actions combinées des bras 7 et 9 amènent la porte à subir une rotation sur elle-même d'environ 90° qui, combinée à l'action du pivotement du bras recourbé 7, fait en sorte que la porte vient finalement se ranger le long de l'aile arrière gauche du véhicule, sans toucher celle-ci, comme représenté sur la figure 3. En variante, l'ouverture de la porte pourrait se faire par l'intermédiaire d'un moteur électrique commandant le pivotement du bras 7 et actionné par un bouton de commande prévu sur une console de commande. La fermeture de la porte s'opère en inversant les mouvements du processus d'ouverture.In the closed position, the slide 11 is located at the end of the portion 12a opposite the elbow 12b, as shown in FIG. 1. The door is opened by pulling on the handle 15 of the lock integrated in the door which has the effect, first, of unlocking the lock and then causing the door to move, in a first phase, in a direction substantially perpendicular to itself, this displacement resulting from the pivoting dextrorsum, of the bent arm 7 around the vertical axis 8, and pivoting senestrorsum, of the door around the vertical axis 10 caused by the arm 9 whose end opposite to the door is subject to move along a path determined by the rail 12 Figure 2 illustrates an open position during this first phase. This first opening phase ends when the slide 11 reaches the bend 12b of the rail. From this moment, the combined actions of the arms 7 and 9 cause the door to undergo a rotation on itself of about 90 ° which, combined with the action of the pivoting of the curved arm 7, causes the door finally comes to line up along the left rear wing of the vehicle, without touching it, as shown in Figure 3. Alternatively, the door could be opened by means of an electric motor controlling the pivoting of the arm 7 and actuated by a control button provided on a control console. The door is closed by reversing the movements of the opening process.

En variante non représentée, le système de charnières pour porte de coffre de véhicule selon l'invention peut être intégré à une porte apte à coopérer, par sa tranche d'extrémité la plus proche du deuxième bras 9, à une seconde porte. Les deux portes forment un dispositif d'obstruction de l'embrasure d'accès au coffre.In a variant not shown, the system of hinges for the vehicle trunk door according to the invention can be integrated into a door capable of cooperating, by its end edge closest to the second arm 9, with a second door. The two doors form a device for obstructing the opening in the boot.

Le dispositif d'obstruction peut comporter deux portes munie du système de charnières selon l'invention, ou une porte munie du système de charnières selon l'invention et une porte battante articulée autour d'au moins un axe vertical. Pour améliorer la cinématique des portes d'un tel dispositif, notamment l'indépendance de l'ouverture de chaque porte par rapport à l'autre porte, l'extrémité de la première portion 12a du rail 12 non raccordée au coude 12b doit être orientée obliquement par rapport au plan de symétrie du véhicule d'un angle supérieur à 45°. Cette extrémité peut par exemple être orientée sensiblement parallèlement au bord inférieur de l'embrasure, par exemple selon un angle de l'ordre de 80° par rapport au plan de symétrie du véhicule. Ainsi, au début de la première phase d'ouverture, la porte est amenée à se déplacer dans une direction sensiblement parallèle à elle-même, puis dans une direction sensiblement perpendiculaire à elle-même comme vu précédemment .The obstruction device may comprise two doors provided with the hinge system according to the invention, or a door provided with the hinge system according to the invention and a hinged door hinged around at least one vertical axis. To improve the kinematics of the doors of such a device, in particular the independence of the opening of each door relative to the other door, the end of the first portion 12a of the rail 12 not connected to the elbow 12b must be oriented obliquely to the plane of symmetry of the vehicle at an angle greater than 45 °. This end can for example be oriented substantially parallel to the lower edge of the doorway, for example at an angle of about 80 ° relative to the plane of symmetry of the vehicle. Thus, at the start of the first opening phase, the door is caused to move in a direction substantially parallel to itself, then in a direction substantially perpendicular to itself as seen above.

Bien entendu, l'invention n'est pas limitée aux modes de réalisation décrits et représentés, fournis à titre illustratif et non limitatif. Of course, the invention is not limited to the embodiments described and shown, provided by way of illustration and not limitation.
