Description

La présente invention concerne un dispositif d'assistance à l'ouverture/fermeture d'ouvrants. Elle concerne en particulier les dispositifs et systèmes d'ouverture/fermeture d'ouvrants latéraux de véhicule, tels que les portes coulissantes latérales.The present invention relates to an assistance device for the opening / closing of opening. It relates in particular to devices and systems for opening / closing vehicle side openings, such as sliding side doors.

Il est déjà connu des systèmes d'assistance à l'ouverture/fermeture de portes latérales de véhicules, notamment par les documents US 5046283 et US 5787636 mais ces dispositifs sont fort complexes et se montent à différent emplacements du véhicule, en intérieur ou en extérieur.It is already known assistance systems opening / closing side doors of vehicles, including documents US 5046283 and US 5787636 but these devices are very complex and are mounted at different locations of the vehicle, indoors or outdoors.

Des améliorations à ces systèmes ont été proposés dans les brevets US 6038818 et US 2004/0195419 et visent à proposer des modules intégrés mais leurs installations nécessitent un espace important et des ajustements du câble d'actionnement pendant l'assemblage sur le véhicule.Improvements to these systems have been proposed in the patents US 6038818 and US 2004/0195419 and aim at providing integrated modules but their installations require a large space and adjustments of the actuating cable during assembly on the vehicle.

II a également été proposé, dans les brevets US 6152519 et US 6481783 , de disposer d'un système dans lequel le rail est déjà monté, ce qui ôte la nécessité de régler suite au montage sur véhicule la longueur du câble d'actionnement.It has also been proposed in patents US 6152519 and US 6481783 , to have a system in which the rail is already mounted, which removes the need to adjust following the vehicle mounting the length of the actuating cable.

L'invention entend remédier aux inconvénients des dispositifs de l'art antérieur en proposant un dispositif d'assistance à l'ouverture/fermeture d'ouvrants simple et particulièrement facile à monter sur le véhicule de sorte que son coût est réduit et sa fiabilité dans le temps accrue.The invention intends to overcome the drawbacks of the devices of the prior art by proposing an assistance device for the opening / closing of opening simple and particularly easy to mount on the vehicle so that its cost is reduced and its reliability in the increased time.

L'invention se rapporte donc à un dispositif d'assistance à l'ouverture/fermeture d'ouvrants, comprenant :

  • une unité de commande apte à entraîner en déplacement un câble pour l'ouverture/fermeture d'un ouvrant,
  • un rail logeant le câble destiné à permettre l'ouverture/fermeture de l'ouvrant, caractérisé en ce que le susdit rail comporte une double paroi, délimitant deux cavités, de sorte que le câble forme une chaîne fermée et s'étend de façon continue dans le rail, une ouverture étant présente dans le rail pour autoriser l'unité de commande à commander le câble.
The invention thus relates to an assistance device for the opening / closing of opening, comprising:
  • a control unit adapted to drive a cable for opening / closing an opening,
  • a rail housing the cable intended to allow the opening / closing of the opening, characterized in that the aforesaid rail comprises a double wall, defining two cavities, so that the cable forms a closed chain and extends continuously in the rail, an opening being present in the rail to allow the control unit to control the cable.

Ainsi, le dispositif d'assistance selon l'invention est plus efficace car l'unité de commande agit directement sur le câble dont le parcours de travail est infini du fait de son enroulement circulaire, ou en boucle, dans un rail à double paroi. Egalement du fait de cet arrangement, on peut placer l'unité de commande à n'importe quel endroit en contact avec le câble du rail, à l'intérieur comme à l'extérieur de habitacle du véhicule. Ceci autorise une grande flexibilité du dispositif et lui permet d'être intégré sur un véhicule quelque soit l'espace disponible, lors de la construction du véhicule mais également pour une monte sur un véhicule d'occasion.Thus, the assistance device according to the invention is more efficient because the control unit acts directly on the cable whose working path is infinite because of its circular winding, or loop, in a double-walled rail. Also because of this arrangement, the control unit can be placed at any place in contact with the rail cable, inside and outside the passenger compartment of the vehicle. This allows a great flexibility of the device and allows it to be integrated on a vehicle whatever the space available, during the construction of the vehicle but also for a ride on a used vehicle.

Par ailleurs, le dispositif d'assistance à l'ouverture/fermeture est facile à monter/fixer sur le véhicule, notamment parce que ledit dispositif est entièrement assemblé préalablement à son montage/fixation sur le véhicule.Moreover, the assistance device opening / closing is easy to mount / fix on the vehicle, especially because said device is fully assembled prior to its mounting / attachment to the vehicle.

Sur la figure 1 sont représentés l'ensemble des éléments composant le dispositif selon l'invention, à savoir un rail à double paroi 1, formant une double cavité logeant un câble, non représenté sur les figures annexées, et une unité de commande 2. Le rail 1 comporte des orifices 3 permettant sa fixation sur le véhicule, ici sur un côté du véhicule car le dispositif est destiné à assister l'ouverture d'une porte latérale coulissante.FIG. 1 shows all the elements making up the device according to the invention, namely a double wall rail 1, forming a double cavity housing a cable, not shown in the appended figures, and a control unit 2. The rail 1 has orifices 3 for attachment to the vehicle, here on one side of the vehicle because the device is intended to assist the opening of a sliding side door.

L'unité de commande 2 comprend un moteur 4, un arbre moteur 5, un logement de tambour 6 logeant le tambour 9.The control unit 2 comprises a motor 4, a drive shaft 5, a drum housing 6 housing the drum 9.

Le moteur 4, typiquement un moteur électrique, sert à la rotation de l'arbre moteur 5, protubérant à une extrémité. Dans l'exemple choisi pour illustrer l'invention sur les figures 1 et 2, une roue d'actionnement 7 est fixée à l'extrémité de l'arbre moteur 5.The motor 4, typically an electric motor, serves for the rotation of the drive shaft 5, protruding at one end. In the example chosen to illustrate the invention in FIGS. 1 and 2, an actuating wheel 7 is fixed to the end of the driving shaft 5.

Le moteur 4 est relié, via ici deux bras de fixation 8, à un tambour 9 constitué d'un logement de tambour 6 dont la surface externe est adaptée pour venir en prise avec le câble du rail 1 de manière à transmettre la rotation du tambour 9 audit câble. Le tambour 9 comprend une partie circulaire périphérique 10 comportant un ensemble de créneaux, ou de dents, aptes à coopérer avec la roue d'actionnement 7 située à l'extrémité de l'arbre moteur 5. La partie circulaire périphérique 10 est assemblée avec le logement de tambour 6 ou ces deux éléments 6, 10 constituent un même ensemble.The motor 4 is connected, via here two fixing arms 8, to a drum 9 consisting of a drum housing 6 whose outer surface is adapted to engage the cable of the rail 1 so as to transmit the rotation of the drum 9 to the cable. The drum 9 comprises a circular peripheral portion 10 comprising a set of crenellations, or teeth, adapted to cooperate with the actuating wheel 7 located at the end of the drive shaft 5. The peripheral circular portion 10 is assembled with the drum housing 6 or these two elements 6, 10 constitute a single together.

Selon une variante de réalisation de l'arbre moteur 5, illustré sur la figure 3, l'extrémité de l'arbre moteur 5 pourra consister en une vis sans fin coopérant avec une roue dentée, non visible sur la figure 3, reliée au tambour 9 et lui transmettant le mouvement dudit arbre moteur 5.According to an alternative embodiment of the drive shaft 5, illustrated in Figure 3, the end of the drive shaft 5 may consist of a worm cooperating with a toothed wheel, not visible in Figure 3, connected to the drum 9 and transmitting to it the movement of said motor shaft 5.

Comme illustré sur les figures 4, 7 et 8, l'unité de commande 2 est fixée au rail double paroi 1, par l'intermédiaire du tambour 9, au niveau d'une ouverture opérée dans la paroi du véhicule et se prolongeant jusqu'à la paroi intérieure du rail. Cette dernière ouverture doit être juste suffisante pour permettre l'accès d'une partie du tambour 9 de sorte que la surface externe de ce dernier contacte le câble et lui communique son mouvement, le cas échéant. Ainsi, lorsque le tambour 9 tourne, le câble se déplace de façon rectiligne.As illustrated in FIGS. 4, 7 and 8, the control unit 2 is fixed to the double wall rail 1, via the drum 9, at an opening made in the wall of the vehicle and extending as far as to the inner wall of the rail. This last opening must be just sufficient to allow access to a portion of the drum 9 so that the outer surface of the latter 9 contacts the cable and communicates its movement, if any. Thus, when the drum 9 rotates, the cable moves rectilinearly.

Le câble n'est pas représenté sur les figures annexées car il consiste en un câble métallique courant apte à être commandé pour son déplacement rectiligne par le tambour 9 de l'unité de commande 2.The cable is not shown in the accompanying figures because it consists of a current metal cable capable of being controlled for its rectilinear movement by the drum 9 of the control unit 2.

Comme illustré notamment sur la figure 6, le rail double paroi 1 comprend une paroi intermédiaire 11 délimitant une première cavité avec la paroi intérieure 12, et délimitant une deuxième cavité, semi ouverte avec la paroi extérieure 13 qui ne s'étend pas jusqu'à l'extrémité inférieure, c'est-à-dire que cette deuxième cavité n'est pas totalement fermée afin notamment d'autoriser le remplacement du câble.As illustrated in particular in FIG. 6, the double wall rail 1 comprises an intermediate wall 11 delimiting a first cavity with the inner wall 12, and delimiting a second, semi-open cavity with the outer wall 13 which does not extend up to the lower end, that is to say that the second cavity is not completely closed in particular to allow the replacement of the cable.

A au moins une extrémité du rail double paroi 1, se trouve un moyen tenseur 14 du câble. Selon un exemple de réalisation du moyen tenseur 14, illustré sur les figures 5a, 5b et 6, ce moyen tenseur 14 comporte :

  • un logement 15 avec une tige centrale traversant 16 légèrement inclinée par rapport aux plans verticaux formés par les parois 11, 12, 13 parallèles du rail 1,
  • un moyen de guidage tel qu'une roue/poulie de renvoi 17,
  • un écrou de fixation 18,
  • deux pions de fixation ou de guidage 19,
  • un ressort 20.
At least one end of the double wall rail 1 is a tensor means 14 of the cable. According to an exemplary embodiment of the tensioning means 14, illustrated in FIGS. 5a, 5b and 6, this tensioning means 14 comprises:
  • a housing 15 with a central through rod 16 slightly inclined relative to the vertical planes formed by the parallel walls 11, 12, 13 of the rail 1,
  • a guiding means such as a wheel / return pulley 17,
  • a fastening nut 18,
  • two fixing or guide pins 19,
  • a spring 20.

Le moyen de guidage, parti intégrante du moyen tenseur, est ici constitué par une roue/poulie 17 fixée au niveau de son centre de symétrie, c'est-à-dire au niveau du centre du cercle que forme ladite roue/poulie 17, sur la tige centrale 16 inclinée du logement 15.The guiding means, integral with the tensor means, is here constituted by a wheel / pulley 17 fixed at its center of symmetry, that is to say at the center of the circle formed by said wheel / pulley 17, on the inclined central rod 16 of the housing 15.

Le logement 15 est fixé au rail 1 par l'intermédiaire de l'écrou 18 et des deux pions 19.The housing 15 is fixed to the rail 1 via the nut 18 and the two pins 19.

L'écrou 18 est positionné de part et d'autre d'un évidement 21 présent à l'extrémité du rail 1. L'écrou 18 est constitué d'un axe central et de deux têtes cylindriques biseautées, d'un diamètre supérieur à la largeur de l'évidement, de sorte que lorsque l'écrou est inséré dans l'évidement, l'axe dudit écrou s'incline légèrement. Cette inclinaison coïncide bien entendu avec celle de la tige centrale du logement, de sorte que la tige centrale 16 puisse s'enfoncer dans l'écrou 18.The nut 18 is positioned on either side of a recess 21 present at the end of the rail 1. The nut 18 consists of a central axis and two beveled cylindrical heads with a diameter greater than the width of the recess, so that when the nut is inserted into the recess, the axis of said nut tilts slightly. This inclination of course coincides with that of the central rod of the housing, so that the central rod 16 can be inserted into the nut 18.

Les deux pions 19, de forme identique, traversent le rail 1 par deux évidements 22, puis le logement 15 au niveau de deux orifices oblongues. Les deux pions 19 sont constitués d'une tige centrale et d'une tête cylindrique biseautée, d'un diamètre supérieur à la largeur de l'évidement, de sorte que lorsque les pions sont insérés dans les évidements, leurs axes s'inclinent légèrement par rapport à la normale du rail, à l'identique du plan formé par le fond 24 du logement 15. A nouveau, l'inclinaison de l'axe des pions 19 est sensiblement la même que celle de la tige centrale 16 et de l'axe de l'écrou 18 de sorte que leur axe soit perpendiculaire avec la surface du logement 15 pour avoir une bonne fixation. Les pions 19 servent à laisser glisser le logement 15 par rapport au rail 1.The two pins 19 of identical shape, pass through the rail 1 by two recesses 22, and the housing 15 at two oblong holes. The two pins 19 consist of a central rod and a beveled cylindrical head, with a diameter greater than the width of the recess, so that when the pins are inserted into the recesses, their axes are inclined slightly relative to the normal of the rail, identical to the plane formed by the bottom 24 of the housing 15. Again, the inclination of the axis of the pins 19 is substantially the same as that of the central rod 16 and the the axis of the nut 18 so that their axis is perpendicular to the surface of the housing 15 to have a good fixation. The pins 19 serve to slide the housing 15 relative to the rail 1.

Enfin, l'ensemble du logement 15 et des éléments qu'il contient est relié à un pion fixe du rail 23, par l'intermédiaire d'un ressort 20, ici hélicoïdal.Finally, the entire housing 15 and the elements it contains is connected to a fixed pin of the rail 23, via a spring 20, here helical.

Le dispositif selon l'invention est tout d'abord basé sur l'utilisation d'un rail double paroi 1 dans lequel vient se loger et se déplacer un câble permettant l'entraînement d'une porte latérale coulissante.The device according to the invention is firstly based on the use of a double wall rail 1 in which is housed and move a cable for driving a sliding side door.

Le rail 1 est constitué d'une première paroi intérieure 12 dont la face externe est accolée et fixée à une paroi du véhicule. La face interne de cette paroi intérieure délimite avec une paroi intermédiaire 11, s'étendant jusqu'à son extrémité inférieure, une première cavité fermée dans laquelle le câble circule. Enfin, une paroi extérieure 13, qui elle ne s'étend pas jusqu'à son extrémité inférieure, délimite avec la paroi intermédiaire, une deuxième cavité semi ouverte, ou semi fermée, dans laquelle circule également le câble.The rail 1 consists of a first inner wall 12 whose outer face is contiguous and attached to a wall of the vehicle. The inner face of this inner wall delimits with an intermediate wall 11, extending to its lower end, a first closed cavity in which the cable flows. Finally, an outer wall 13, which does not extend to its lower end, defines with the intermediate wall, a second semi-open cavity, or semi-closed, in which also circulates the cable.

Le rail 1 est donc constitué de deux cavités. La première, côté intérieur, est totalement fermée, à l'exception des extrémités longitudinales pour permettre la circulation du câble, et évidemment au niveau du tambour 9. La seconde, côté extérieur, est semi ouverte ou semi fermée, de sorte que le câble est accessible pour son retrait ou sa réparation. Bien entendu, on pourra prévoir que la première cavité présente la même cavité semi-ouverte, ou semi-fermée, que celle de la seconde cavité.The rail 1 therefore consists of two cavities. The first, inner side, is completely closed, with the exception of the longitudinal ends to allow the circulation of the cable, and obviously at the drum 9. The second, outer side, is semi open or semi closed, so the cable is accessible for removal or repair. Of course, it can be provided that the first cavity has the same semi-open cavity, or semi-closed, than that of the second cavity.

Dans un autre mode de réalisation, la cavité, côté intérieure, pourra être délimitée directement par la paroi du véhicule et la paroi intermédiaire 11 du rail 1. Ainsi, dans ce mode de réalisation, la paroi intérieure 12 du rail a été supprimée.In another embodiment, the cavity, inner side, may be delimited directly by the vehicle wall and the intermediate wall 11 of the rail 1. Thus, in this embodiment, the inner wall 12 of the rail has been removed.

Le câble forme à l'intérieur de ces deux cavités du rail une chaîne continue, ou fermée, s'étendant de façon rectiligne, ou linéaire, dans le rail.The cable forms inside these two cavities of the rail a continuous or closed chain extending rectilinearly or linearly in the rail.

Le moyen de guidage, ici la roue/poulie 17, est fixé légèrement incliné par rapport à l'axe vertical, c'est-à-dire l'axe des parois intérieure 12, intermédiaire 11 et extérieure 13 du rail à double paroi 1. Cette inclinaison est de préférence choisie de l'ordre de 9°, mais elle sera généralement comprise entre 5° et 15°.The guide means, here the wheel / pulley 17, is fixed slightly inclined with respect to the vertical axis, that is to say the axis of the inner walls 12, 11 intermediate and outer 13 of the double wall rail 1 This inclination is preferably chosen on the order of 9 °, but it will generally be between 5 ° and 15 °.

La roue/poulie 17 permet d'une part, de faire changer la direction de déplacement du câble en bout de rail, et d'autre part, du fait de son inclinaison, de faire passer le câble de la cavité intérieure du rail vers la cavité extérieure, de sorte que le câble autorise une longueur de travail, ou de débattement, c'est-à-dire un trajet d'actionnement, quasi-infinie. On pourra prévoir classiquement que le câble soit composé de deux sections au lieu d'une seule, chacune des sections étant fixée par l'une de ses extrémités au tambour 9 et par l'autre de ses extrémités à la porte coulissante ou a l'interface avec la porte coulissante, classiquement un chariot a roulette conçu pour translater dans la partie extérieure semi ouverte du rail.The wheel / pulley 17 makes it possible, on the one hand, to change the direction of movement of the cable at the end of the rail and, on the other hand, because of its inclination, to pass the cable from the interior cavity of the rail towards the outer cavity, so that the cable allows a working length, or deflection, that is to say a drive path, almost infinite. It can be conventionally provided that the cable is composed of two sections instead of one, each of the sections being fixed by one of its ends to the drum 9 and the other of its ends to the sliding door or to the interface with the sliding door, conventionally a wheeled trolley designed to translate in the semi-open outer part of the rail.

La roue/poulie 17 est également inclinée de manière à ce que sa partie supérieure se retrouve en face de la cavité extérieure semi ouverte, et que sa partie inférieure se retrouve en face de la cavité intérieure fermée. Le câble sera donc guidé et tendu dans la partie supérieure fermée de la cavité extérieure, évitant ainsi toute possibilité de sortie du câble de la cavité. Ainsi, le câble se trouve toujours encadré ou guidé par/grâce les/aux parois du rail 1 tout en autorisant la prise/récupération facile du câble.The wheel / pulley 17 is also inclined so that its upper portion is found in front of the semi-open outer cavity, and that its lower portion is in front of the closed interior cavity. The cable will therefore be guided and stretched in the closed upper part of the outer cavity, thus avoiding any possibility of cable exit from the cavity. Thus, the cable is always framed or guided by / thanks to / the walls of the rail 1 while allowing the easy catch / recovery of the cable.

La tige centrale 16 du logement s'étend à l'extérieur jusque dans un écrou 18 positionné dans un évidement 21 présent à l'extrémité du rail 1.The central rod 16 of the housing extends outwardly into a nut 18 positioned in a recess 21 at the end of the rail 1.

Le logement 15 est également traversé par deux pions 19 positionnés dans deux évidements 22 et situés entre la roue/poulie et l'entrée des deux cavités du rail pour faciliter le guidage du logement 15 sur la surface du rail.The housing 15 is also traversed by two pins 19 positioned in two recesses 22 and located between the wheel / pulley and the inlet of the two cavities of the rail to facilitate guiding the housing 15 on the surface of the rail.

Les évidements 21, 22 dans lesquels viennent se loger les deux pions de guidage 19 et la tige centrale 16 permettent au logement 15 de coulisser en étant guidé par lesdits évidement 21, 22. Le coulissement du logement 15 s'effectue en translation suivant l'axe longitudinal du rail 1, c'est-à-dire suivant le prolongement axial dudit rail 1 à ses extrémités respectives.The recesses 21, 22 in which are housed the two guide pins 19 and the central rod 16 allow the housing 15 to slide guided by said recess 21, 22. The sliding of the housing 15 is in translation according to the longitudinal axis of the rail 1, that is to say along the axial extension of said rail 1 at its respective ends.

Enfin, afin d'assurer la tension du câble, un ressort de tension 20 est relié d'une part à un pion 23, fixé à l'extrémité du rail 1, et d'autre part à une partie solidaire du logement 15. Dans le mode de réalisation choisi pour illustrer l'invention, il s'agit de la tige centrale 16 du logement 15 , mais on pourra envisager de fixer ce ressort 20 à d'autres emplacements sur la roue/poulie 17 ou sur l'un des susdits pions 19.Finally, in order to ensure the tension of the cable, a tension spring 20 is connected on the one hand to a pin 23, attached to the end of the rail 1, and on the other hand to a portion secured to the housing 15. In the embodiment chosen to illustrate the invention, it is the rod 16 of the housing 15, but it may be envisaged to fix this spring 20 at other locations on the wheel / pulley 17 or on one of the aforementioned pins 19.

Le câble est mis en mouvement au moyen d'une unité de commande 2 comprenant un moteur 4, un arbre moteur 5 et un tambour 9.The cable is set in motion by means of a control unit 2 comprising a motor 4, a motor shaft 5 and a drum 9.

Lorsque le tambour 9 est mis en mouvement de rotation par le moteur 4, il communique un mouvement au câble, soit pour fermer l'ouvrant selon un sens de rotation du tambour 9 soit pour l'ouvrir selon l'autre sens de rotation du tambour 9.When the drum 9 is rotated by the motor 4, it communicates a movement to the cable, either to close the opening in a direction of rotation of the drum 9 or to open in the other direction of rotation of the drum 9.

Ainsi, suivant le sens de rotation de l'arbre moteur 5, le tambour 9 communique un déplacement au câble pour assurer l'ouverture ou la fermeture de la porte latérale coulissante.Thus, according to the direction of rotation of the drive shaft 5, the drum 9 communicates a displacement cable to ensure the opening or closing of the sliding side door.

L'unité de commande 2 est fixée au rail à double paroi 1, par l'intermédiaire du tambour 9, au niveau d'une ouverture opérée dans la paroi du véhicule et se prolongeant jusqu'à la paroi intérieure 12 du rail 1.The control unit 2 is fixed to the double-walled rail 1, via the drum 9, at an opening made in the vehicle wall and extending as far as the inner wall 12 of the rail 1.

De manière à prendre en compte les contraintes d'encombrement au niveau du module de porte latérale coulissante, l'ouverture peut être réalisée à n'importe quel endroit sur la longueur du rail 1.In order to take into account the space constraints at the sliding side door module, the opening can be made at any point along the length of the rail 1.

De plus, l'ouverture doit être juste suffisante pour permettre l'accès d'une partie du tambour 9 de sorte que la surface externe de ce dernier contacte le câble et lui communique son mouvement.In addition, the opening must be just sufficient to allow access to a portion of the drum 9 so that the outer surface of the latter contacts the cable and communicates its movement.

Pour permettre la régulation du mouvement de la porte coulissante, des capteurs électroniques de type potentiomètres ou à effet hall (ou autres) seront intégrés au système lors de la conception. Un capteur de position potentiométrique pourra par exemple être intégré directement au tambour, plus particulièrement sur l'axe de ce dernier. Des capteurs de position pourront aussi être intégrés sur le rail, et plus particulièrement à l'intérieur de la cavité du rail à double paroi, notamment aux deux extrémités du rail. Les ouvertures servant à la fixation du rail à double paroi sur le véhicule peuvent servir de support à ces capteurs.In order to regulate the movement of the sliding door, electronic sensors of the potentiometer or hall effect type (or others) will be integrated into the system during the design phase. A potentiometric position sensor may for example be integrated directly to the drum, more particularly on the axis of the drum. Position sensors may also be integrated on the rail, and more particularly within the cavity of the double-walled rail, in particular at both ends of the rail. The openings for fixing the double-walled rail to the vehicle can serve as a support for these sensors.

Le tambour 9 sera ainsi en contact avec la partie du câble qui circule dans la cavité intérieure du rail. Le tambour 9 est localisé en partie à l'intérieur et en partie à l'extérieur du véhicule. On notera que le rail à double paroi sert de support à toutes les pièces du dispositif, formant un module.The drum 9 will thus be in contact with the portion of the cable that circulates in the inner cavity of the rail. The drum 9 is located partly inside and partly outside the vehicle. It will be noted that the double-walled rail serves as a support for all the parts of the device, forming a module.

On notera que l'unité de commande est apte à tourner autour de l'axe du tambour 9 afin de faciliter le montage, en étant insérée depuis l'extérieur du véhicule.Note that the control unit is rotatable about the axis of the drum 9 to facilitate assembly, being inserted from outside the vehicle.

Il est évident par ailleurs que le rail pourra comprendre n cavités et un nombre adéquats de moyen tenseur du câble, par exemple trois cavités et quatre moyens tenseur, situés deux à deux, à chacune des extrémités dudit rail.It is also clear that the rail may comprise n cavities and an adequate number of tensor means of the cable, for example three cavities and four tensioning means, located in pairs, at each end of said rail.
