Description

La présente invention concerne un dispositif de fermeture pour une portière latérale de véhicule automobile, notamment un véhicule automobile qui présente sur au moins un côté, deux portières latérales côte à côte et jointives, sans pied milieu de séparation.The present invention relates to a closure device for a side door of a motor vehicle, in particular a vehicle automobile that has on at least one side, two side doors side by side and joined, without foot middle of separation.

Habituellement, les véhicules qui présentent quatre portières latérales, comportent sur chaque côté du véhicule, deux portières latérales séparées par un pied milieu sur lequel une gâche est fixée sensiblement à mi-hauteur, en vis-à-vis de la serrure de la portière latérale avant du véhicule.Usually, vehicles with four doors side, have on each side of the vehicle, two doors sides separated by a central foot on which a strike is fixed noticeably halfway up, opposite the lock of the door front side of the vehicle.

Toutefois, lorsque ce pied milieu est supprimé, il est nécessaire de prévoir la gâche sur un autre élément du véhicule. Si cette gâche est fixée sur la portière latérale arrière du véhicule, il n'est pas possible d'ouvrir la portière arrière avant d'avoir ouvert la portière avant, et il n'est pas possible de fermer la portière avant avant d'avoir fermé la portière arrière, ce qui est particulièrement gênant.However, when this middle foot is removed, it is necessary to provide the keeper on another element of the vehicle. If this waste is attached to the rear side door of the vehicle, it is not possible to open the rear door before opening the front door, and It is not possible to close the front door before closing the door. rear door, which is particularly troublesome.

L'invention a pour but d'éliminer les inconvénients précités et de proposer un dispositif de fermeture pour une portière latérale de véhicule automobile, qui puisse assurer une fermeture fiable de la portière, même en l'absence de pied milieu, tout en ayant un encombrement minimum et une structure simple et peu coûteuse.The object of the invention is to eliminate the aforementioned drawbacks and to propose a closing device for a side door of motor vehicle, which can ensure a reliable closure of the door, even in the absence of a center pillar, while having a minimum footprint and a simple and inexpensive structure.

US-A-4,662,109 montre un dispositif selon le préambule de la revendication 1.US-A-4,662,109 shows a device according to the preamble of claim 1.

A cet effet, l'invention a pour objet un dispositif de fermeture pour une portière latérale de véhicule automobile, comportant une serrure destinée à être fixée sur ladite portière, ladite serrure contenant un pêne rotatif et un cliquet rotatif de blocage du pêne dans sa position de rétention d'une gâche fixée à la caisse du véhicule, et des moyens de déclenchement d'ouverture de la serrure aptes à coopérer avec le cliquet pour le déplacer en position de libération du pêne sous l'action d'un organe de commande d'ouverture intérieur ou extérieur de la portière, caractérisé par le fait qu'il comporte au moins un organe de retenue escamotable destiné à être monté sur ladite portière, pour s'engager dans un renfoncement prévu sur la caisse du véhicule, ledit organe escamotable étant relié par un moyen de liaison à une biellette de commande qui coopère avec le pêne précité, pour maintenir ledit organe de retenue en position escamotée lorsque le pêne est dans sa position de libération de la gâche.For this purpose, the subject of the invention is a closure device for a side door of a motor vehicle, comprising a lock to be fixed on said door, said lock containing a rotary bolt and a locking pawl of the bolt in its position retention of a striker attached to the vehicle body, and means of triggering the opening of the lock capable of cooperating with the ratchet for moving it to the release position of the bolt under the action of an opening control member inside or outside the door, characterized in that it comprises at least one retractable retainer for mounting on said door, for engage in a recess provided on the vehicle body, said retractable member being connected by connecting means to a connecting rod control which cooperates with the aforementioned bolt, to maintain said retainer in the retracted position when the bolt is in its release position of the striker.

Avantageusement, ladite biellette de commande est montée pivotante dans le boítier de la serrure précitée, de façon que l'une des extrémités de ladite biellette vienne en contact avec le profil périphérique du pêne, et l'extrémité opposée de ladite biellette, par rapport à son axe de pivotement, soit reliée par ledit moyen de liaison à l'organe de retenue précité.Advantageously, said control rod is mounted swivel in the housing of the aforementioned lock, so that one of the ends of said link comes into contact with the profile device of the bolt, and the opposite end of said link, by relative to its pivot axis, is connected by said connecting means to the aforementioned retainer.

Dans une forme de réalisation préférée, les moyens de déclenchement d'ouverture précités sont aptes à coopérer avec la biellette de commande pour la basculer en position d'escamotage de l'organe de retenue, sous l'action de l'organe de commande d'ouverture intérieur ou extérieur de la portière. Ainsi, avec une action sur la poignée extérieure ou intérieure de portière, on obtient à la fois le retrait de l'organe de retenue et la libération du pêne de la serrure.In a preferred embodiment, the means for aforementioned opening releases are able to cooperate with the control rod to switch it to the retracted position of the retaining member, under the action of the control member opening inside or outside the door. So with an action on the outer or inner door handle, one gets at once removing the retaining member and releasing the bolt from the lock.

Dans ce cas, on peut prévoir que le pêne présente sur une partie de sa périphérie un profil contre lequel vient en appui ladite extrémité de la biellette de commande, pendant toute la course de pivotement du pêne vers sa position de libération de la gâche, pour maintenir l'organe de retenue dans sa position escamotée. Ainsi, l'organe de retenue ne risque pas d'empêcher l'ouverture de la serrure.In this case, it is possible that the bolt present on a part its periphery a profile against which supports said end of the control rod, during the entire pivoting stroke of the bolt to its release position of the strike, to maintain the organ restraint in its retracted position. Thus, the retainer may not prevent the lock from being opened.

De préférence, le profil précité du pêne présente un décrochement qui est apte à recevoir l'extrémité en vis-à-vis de la biellette de commande, lorsque le pêne est en position de fermeture, pour à la fois permettre à la biellette de commande de revenir dans la position dans laquelle l'organe de retenue est en position saillante et empêcher la rotation du pêne, tant que la biellette de commande n'a pas basculé vers la position d'escamotage de l'organe de retenue.Preferably, the aforementioned profile of the bolt has a recess which is adapted to receive the end opposite the control rod, when the bolt is in the closed position, to both allow the control rod to come back into the position in which the retaining member is in a projecting position and prevent rotation of the bolt until the control rod has tilted to the retracted position of the retaining member.

Selon encore une autre caractéristique de l'invention, l'organe de retenue est sollicité vers sa position saillante par un ressort de rappel.According to yet another characteristic of the invention, the organ of restraint is biased towards its projecting position by a return spring.

Avantageusement, le moyen de liaison précité est un câble reliant une extrémité de la biellette de commande à l'organe de retenue.Advantageously, the aforementioned connecting means is a connecting cable one end of the control rod to the retaining member.

Dans une autre forme de réalisation, la biellette de commande est, en permanence, en appui par une extrémité qui constitue un élément suiveur de came, sur un profil de came à la périphérie du pêne, ledit profit de came étant apte à provoquer un basculement de la biellette vers sa position d'escamotage de l'organe de retenue, dès le début de la rotation du pêne vers sa position de libération de la gâche, le bras de levier de la biellette de commande étant tel qu'une faible rotation du pêne provoque l'escamotage de l'organe de retenue.In another embodiment, the control rod is permanently supported by one end which constitutes a cam follower element, on a cam profile at the periphery of the bolt, said cam profit being able to cause a tilting of the rod towards its position of retraction of the retaining member, from the beginning of the rotation of the bolt towards its release position of the striker, the lever arm of the control rod being such that a weak rotation of the bolt causes the retraction of the retaining member.

Dans ce cas, la somme de la force de compression des joints de portière et de la force de rappel du ressort associé au pêne est supérieure à la force de rappel du ressort associé à l'organe de retenue.In this case, the sum of the compression force of the seals door and the return force of the spring associated with the bolt is greater than the restoring force of the spring associated with the retaining member.

L'invention vise également un véhicule automobile présentant sur au moins un côté, deux portières latérales côte à côte et jointives, sans montant vertical intercalaire de séparation, l'une au moins des portières étant articulée sur la caisse par son bord vertical opposé à l'autre portière, ladite portière articulée étant équipée du dispositif précité, caractérisé par le fait que ladite serrure est montée sur la partie inférieure de la portière articulée en vis-à-vis d'une gâche fixée sur la partie inférieure de la caisse, sensiblement au niveau du plancher, alors que l'organe de retenue escamotable est monté sur la partie supérieure de l'encadrement de la vitre de la portière, en vis-à-vis d'un renfoncement dans la partie supérieure de la caisse, sensiblement au niveau du pavillon du véhicule.The invention also relates to a motor vehicle having on at least one side, two side doors side by side and joined, without vertical separating pillar, at least one of the doors being articulated on the body by its vertical edge opposite to the other door, said articulated door being equipped with the aforementioned device, characterized in that said lock is mounted on the part lower part of the articulated door opposite a strike fixed on the lower part of the body, substantially at floor level, then that the retractable retaining member is mounted on the upper part of the frame of the window of the door, vis-à-vis a recess in the upper part of the body, substantially at level of the vehicle's roof.

De préférence, l'organe de retenue est constitué d'un doigt mobile dans la direction verticale. Ainsi, il suffit de ménager un renfoncement dans le longeron latéral du pavillon du véhicule, ce qui évite toute surépaisseur à l'endroit où l'utilisateur passe la tête pour entrer ou sortir du véhicule.Preferably, the retaining member consists of a finger mobile in the vertical direction. Thus, it is enough to spare a recess in the side spar of the vehicle roof, which avoids any extra thickness where the user passes the head for enter or exit the vehicle.

Pour mieux faire comprendre l'objet de l'invention, on va en décrire maintenant, à titre d'exemples purement illustratifs et non limitatifs, plusieurs modes de réalisation représentés sur le dessin annexé.To better understand the object of the invention, we will describe now, as purely illustrative and non-illustrative examples restrictive, several embodiments shown in the drawing Annex.

Sur ce dessin :

  • la figure 1 est une vue schématique fonctionnelle du dispositif de fermeture selon un mode de réalisation de l'invention ;
  • la figure 2 est une vue analogue à la figure 1, mais suivant une variante de réalisation ; et
  • la figure 3 est une vue schématique d'une portière latérale avant de véhicule automobile équipée du dispositif de fermeture de l'invention.
On this drawing :
  • Figure 1 is a schematic functional view of the closure device according to one embodiment of the invention;
  • Figure 2 is a view similar to Figure 1, but according to an alternative embodiment; and
  • Figure 3 is a schematic view of a front side door of a motor vehicle equipped with the closure device of the invention.

Sur la figure 3, on a représenté une portière latérale avant P pour un véhicule automobile, ladite portière P comportant un caisson inférieur 1 qui est destiné à être articulé par son bord vertical avant 2 sur la caisse du véhicule, et un encadrement supérieur 3 pour une vitre 4.FIG. 3 shows a front side door P for a motor vehicle, said door P comprising a casing lower 1 which is intended to be articulated by its vertical edge before 2 on the vehicle body, and a top frame 3 for a window 4.

La portière P comporte au voisinage de son bord vertical 5, opposé à son bord articulé 2, un doigt de retenue 6 qui fait verticalement saillie par rapport à la partie supérieure de l'encadrement de vitre 3. Un boítier de serrure 7 est logé dans le caisson 1, sensiblement au voisinage de l'angle formé par le bord inférieur 8 et le bord vertical 5 de la portière P. L'avaloir 7a du boítier de serrure 7 est ouvert dans la direction transversale vers l'intérieur du véhicule et dans la direction verticale, vers le bas du véhicule, lorsque la portière P est fermée, de manière à recevoir une gâche 9 qui est destinée à être fixée sur un longeron latéral inférieur de la caisse du véhicule, sensiblement au niveau du plancher. La gâche 9 peut être constituée d'une plaquette 9a fixée par deux vis 10 audit longeron, avec une tige métallique 11 en forme de U inversé fixée à ladite plaquette 9 par les extrémités libres du U. La tige 11 en U s'étend dans un plan sensiblement transversal et vertical du véhicule. L'une des branches de la tige 11 en U est destinée à être retenue par le pêne 12 de la serrure 7.The door P has in the vicinity of its vertical edge 5, opposite its hinged edge 2, a retaining finger 6 which is vertically protruding from the upper part of the window frame 3. A lock housing 7 is housed in the casing 1, substantially in the vicinity of the angle formed by the lower edge 8 and the vertical edge 5 of the door P. The duct 7 has lock casing 7 is open in the transverse direction towards the inside of the vehicle and in the vertical direction, towards the bottom of the vehicle, when the door P is closed, so as to receive a keeper 9 which is intended to be fixed on a lower side sill of the vehicle body, substantially at the floor. The keeper 9 may be constituted by a plate 9 is fixed by two screws 10 to said beam, with a metal U shaped rod 11 attached to said inverted wafer 9 by the free ends of the U. The U rod 11 extends in a substantially transverse and vertical plane of the vehicle. One of the branches of the U-shaped rod 11 is intended to be retained by the bolt 12 of the lock 7.

Comme visible sur la figure 3, un câble de liaison 13 est relié à une extrémité au doigt verticalement mobile 6 et à son extrémité opposée au boítier de serrure 7.As can be seen in FIG. 3, a connecting cable 13 is connected to a vertically movable finger end 6 and at its end opposite the lock housing 7.

Bien que cela ne soit pas représenté, la serrure 7 est liée, de manière connue en soi, à une poignée intérieure de portière et une poignée extérieure de portière, pour commander l'ouverture de la serrure. En outre, cette serrure peut contenir des organes de condamnation et de décondamnation, pour condamner la serrure vis-à-vis de l'intérieur et/ou de l'extérieur. Cette portière peut également être munie d'un barillet destiné à commander mécaniquement la condamnation et la décondamnation de la serrure 7.Although this is not shown, the lock 7 is linked, from known manner, to an interior door handle and a outside door handle, to control the opening of the door lock. In addition, this lock may contain condemnation and unlocking, to condemn the lock vis-à-vis from the inside and / or the outside. This door can also be equipped with a cylinder intended to mechanically control the conviction and unlocking of the lock 7.

On va maintenant se référer à la figure 1 pour décrire le fonctionnement du dispositif de fermeture de l'invention. De manière connue en soi, le pêne 12 est monté rotatif autour d'un axe 14 dans le boítier de serrure et présente une forme en fourche avec deux crans de fermeture 12a et 12b. Les crans 12a et 12b sont destinés à coopérer avec un cran correspondant 15a d'un cliquet de blocage 15 articulé en 16 dans le boítier de serrure 7. Le cliquet 15 comporte un pion d'actionnement 15b pour provoquer sa rotation dans le sens anti-horaire, lors d'une commande d'ouverture de la portière, afin de libérer le pêne. Lorsque le pêne 12 est libre de tourner, il pivote dans le sens horaire vers sa position d'ouverture qui libère la gâche 11, sous l'action d'un ressort de rappel (non illustré) et de la force de réaction des joints de portière.Reference will now be made to FIG. 1 to describe the operation of the closure device of the invention. Manner known per se, the bolt 12 is rotatably mounted about an axis 14 in the lock housing and has a fork shape with two closure notches 12 a and 12 b. The notches 12 a and 12 b are intended to cooperate with a corresponding notch 15 has a hinge 15 locking pawl 16 in the housing 7. The lock pawl 15 has an actuating pin 15 b to cause its rotation in counter-clockwise, during an opening command of the door, to release the bolt. When the bolt 12 is free to rotate, it pivots clockwise towards its open position which releases the striker 11, under the action of a return spring (not shown) and the reaction force of the seals. door.

A titre d'exemple, le pion d'actionnement 15b du cliquet 15 est relié par un câble 17 aux poignées intérieure et extérieure de portière, schématiquement représentées en 18. Bien entendu, cette représentation est purement schématique car, en général, le câble 17 est relié à des leviers d'ouverture dans le boítier de serrure, pour actionner le cliquet 15, ces leviers d'ouverture pouvant être bloqués ou débrayés, par des moyens de condamnation/décondamnation de la serrure.For example, the actuating piece 15b of the pawl 15 is connected by a cable 17 to the inner and outer door handles, shown schematically at 18. Of course, this is purely schematic representation since, in general, the cable 17 is connected to the opening levers in the lock housing, to actuate the pawl 15, these opening levers can be blocked or disengaged by means of locking / unlocking the lock.

On voit sur la figure 1 que la poignée extérieure ou intérieure 18 de la portière est reliée par un autre câble 19 à une biellette de commande 20. Cette biellette 20 est articulée en 21 dans le boítier de serrure et est reliée à une extrémité 20a à une tringle 22 portant le doigt de retenue 6 précité. Bien entendu, la tringle 22 pourrait être remplacée par le câble 13 précité. Un ressort de rappel 23 est intercalé entre le doigt de retenue 6 et la partie supérieure de l'encadrement 3 de la portière P, pour solliciter l'organe de retenue 6 dans un renfoncement 24 du pavillon du véhicule V. Le câble 19 est relié à la biellette de commande 20 en un point 19a situé entre l'articulation 21 et le point de liaison 20a à la tringle 22.It is seen from Figure 1 that the outer or inner handle 18 of the door is connected by another cable 19 to a control link 20. This link 20 is hinged at 21 in the lock housing and is connected to one end 20a to a rod 22 carrying the aforementioned retaining finger 6. Of course, the rod 22 could be replaced by the cable 13 mentioned above. A return spring 23 is interposed between the retaining finger 6 and the upper part of the frame 3 of the door P, to urge the retaining member 6 in a recess 24 of the roof of the vehicle V. The cable 19 is connected the control rod 20 at a point 19 situated between the articulation 21 and the connection point 20 has the rod 22.

Bien entendu, des leviers d'ouverture peuvent être intercalés entre le câble 19 et la biellette 20, pour permettre de bloquer ou débrayer lesdits leviers en position condamnée de la serrure.Of course, opening levers can be inserted between the cable 19 and the link 20, to allow blocking or disengaging said levers in the locked position of the lock.

L'extrémité 20b de la biellette de commande 20, opposée à l'extrémité 20a, par rapport à l'axe d'articulation 21, est en vis-à-vis d'une portée d'appui 25 constituée par un décrochement sur la périphérie du pêne 12, lorsque la biellette de commande 20 est dans la position dans laquelle le doigt de retenue 6 est engagé dans le renfoncement 24 et le pêne 12 est dans sa position de fermeture. Dans cette position, la biellette de commande 20 empêche le pêne 12 de pivoter vers sa position d'ouverture.The end 20 b of the link control unit 20, opposite the end 20a, relative to the hinge pin 21, is vis-à-vis a bearing surface 25 formed by a step on the periphery of the bolt 12, when the control rod 20 is in the position in which the retaining finger 6 is engaged in the recess 24 and the bolt 12 is in its closed position. In this position, the control rod 20 prevents the bolt 12 from pivoting to its open position.

Lorsque la biellette de commande 20 pivote dans le sens horaire, comme indiqué par la flèche F, l'extrémité 20b de ladite biellette échappe à la portée d'appui 25 et peut venir en contact avec un profil périphérique 26 du pêne 12, lors de sa rotation vers sa position de libération de la gâche 11. Le profil périphérique 26 est adapté pour maintenir la biellette de commande 20 dans sa position basculée correspondant à la position escamotée du doigt de retenue 6.When the control rod 20 pivots in a clockwise direction, as indicated by the arrow F, the end 20b of said rod escapes the bearing surface 25 and can come into contact with a peripheral profile 26 of the bolt 12, when its rotation towards its release position of the keeper 11. The peripheral profile 26 is adapted to maintain the control rod 20 in its tilted position corresponding to the retracted position of the retaining finger 6.

Ainsi, lors d'une commande d'ouverture sur la poignée intérieure ou extérieure 18 de la portière P, le câble de liaison 19 provoque d'abord le pivotement de la biellette de commande 20, pour escamoter le doigt de retenue 6, puis le pivotement du cliquet 15, ce qui libère la rotation du pêne 12, ce dernier maintenant la biellette de commande 20 dans sa position basculée d'escamotage, grâce au profil 26 qui vient en appui contre l'extrémité 20b de la biellette de commande 20.Thus, during an opening command on the inner or outer handle 18 of the door P, the connecting cable 19 first causes the pivoting of the control rod 20, to retract the retaining finger 6, then the pivoting of the pawl 15, which releases the rotation of the bolt 12, the latter now the control rod 20 in its tilted retraction position, thanks to the profile 26 which abuts against the end 20b of the control rod 20 .

Inversement, lorsque la portière est refermée, la gâche 11 s'engage dans la fourche du pêne 12, ce qui provoque sa rotation dans le sens anti-horaire jusqu'à ce que le cran 15a du cliquet 15 s'enclenche sur le cran 12a du pêne 12. Dans cette position, l'extrémité 20b de la biellette de commande 20 n'est plus en contact avec le profil 26 du pêne 12 et peut basculer en face de la portée d'appui 25, sous l'effet de la force de rappel du ressort 23 associé à l'organe de retenue 6. Etant donné que la portière est dans sa position complètement fermée, lorsque la biellette de commande 20 bascule vers sa position illustrée sur la figure 1, il est garanti que le renfoncement 24 soit bien aligné dans la direction verticale avec le doigt de retenue 6.Conversely, when the door is closed, the striker 11 engages in the fork of the bolt 12, which causes its rotation in the counterclockwise direction until the notch 15 has ratchet 15 engages on the notch 12 has the bolt 12. in this position, the end 20 b of the operating rod 20 is no longer in contact with the profile 26 of the bolt 12 and can be pivoted in front of the bearing surface 25 under the effect of the return force of the spring 23 associated with the retaining member 6. Since the door is in its fully closed position, when the control rod 20 switches to its position shown in FIG. 1, it is ensured that the recess 24 is aligned in the vertical direction with the retaining finger 6.

En revanche, si la portière n'est fermée qu'au premier cran 12b la biellette 20 sera maintenue basculée et le doigt de retenue 6 sera escamoté.On the other hand, if the door is closed only at the first notch 12 b, the rod 20 will be kept tilted and the retaining finger 6 will be retracted.

Pour que la biellette de commande 20 pivote avant le cliquet 15, il suffit que le câble 19 soit plus tendu que le câble 17 ou bien que le câble 17 soit plus lâche que le câble 19.So that the control rod 20 pivots before the pawl 15, it suffices that the cable 19 is tighter than the cable 17 or that the cable 17 is looser than the cable 19.

Dans la variante illustrée sur la figure 2, le câble de liaison 19 entre la poignée de portière 18 et la biellette de commande 120 a été supprimé. La biellette de commande 120 est articulée en 121 dans le boítier de serrure et reliée par son extrémité 120a à la tringle de liaison 22 précitée. L'extrémité opposée 120b de la biellette de commande 120 est en appui permanent avec un profil de came 126 à la périphérie du pêne 12. Ce profil de came 126 est adapté pour provoquer le pivotement de la biellette de commande 120 dans la direction de la flèche F sur la figure 2, dès le début de la rotation du pêne 12 vers sa position d'ouverture. Ainsi, c'est le début de la course de rotation du pêne 12 vers sa position d'ouverture qui provoque le basculement de la biellette de commande 120 et donc, l'escamotage du doigt de retenue 6. A cet effet, la distance entre les points 120a et 121 est nettement supérieure à celle entre les points 121 et 120b, de façon qu'un léger basculement angulaire de la biellette de commande 120 provoque une course de translation suffisante du doigt de retenue 6.In the variant illustrated in Figure 2, the connecting cable 19 between the door handle 18 and the control rod 120 has been removed. The control rod 120 is hinged at 121 in the lock housing and connected at its end 120a to the aforementioned connecting rod 22. The opposite end 120 b of the rocker bar operating cam 120 is in permanent abutment with a cam 126 at the periphery of the bolt 12. The cam profile 126 is adapted to cause the pivoting of the control rod 120 in the direction of arrow F in Figure 2, from the beginning of the rotation of the bolt 12 to its open position. Thus, it is the beginning of the rotational stroke of the bolt 12 towards its open position which causes the tilting of the control rod 120 and thus, the retraction of the retaining finger 6. For this purpose, the distance between points 120 a and 121 is markedly greater than that between the points 121 and 120 b, so that a slight angular tilting the control rod 120 causes a sufficient translation stroke of the retention finger 6.

Bien entendu, la position verticale du doigt de retenue 6 peut être réglée par la longueur de la tringle 22 ou du câble de liaison 13. Le doigt de retenue 6 présente une résistance au cisaillement suffisante, pour empêcher une personne mal intentionnée de tordre la portière par le haut.Of course, the vertical position of the retaining finger 6 can be adjusted by the length of the rod 22 or the connecting cable 13. The retaining finger 6 has sufficient shear strength, to prevent an ill-intentioned person from bending the door by the top.

Dans le dispositif de fermeture de l'invention, le déplacement de l'organe de retenue supérieur de la portière est asservi mécaniquement au déplacement du pêne de la serrure inférieure.In the closure device of the invention, the displacement of the upper retainer of the door is mechanically controlled moving the bolt of the lower lock.

Le fait d'avoir une fixation de la portière par des points haut et bas permet également de réduire ou éliminer les éventuels bruits aérodynamiques au roulage, en plaquant la portière contre les joints sur la caisse.The fact of having a door fixing by high points and low also helps reduce or eliminate any noises aerodynamic when rolling, pressing the door against the seals on the box.
