Description

AGENCEMENT D'UN COFFRE POUR VEHICULE EQUIPE D'UN TENDELET ESCAMOTABLE  ARRANGEMENT OF A BOOT FOR A VEHICLE EQUIPPED WITH A RETRACTABLE TENDER
L'invention concerne un agencement d'un coffre pour véhicule automobile équipé d'un tendelet escamotable dans un logement. The invention relates to an arrangement of a trunk for a motor vehicle equipped with a retractable tendelet in a housing.
Certains coffres longs, en particulier des coffres à hayon, comportent un tendelet pour cacher le contenu du coffre lorsque ce dernier est fermé. Le tendelet est constitué d'un rideau souple monté sur un enrouleur logé dans un boîtier rigide. Le tendelet est fixé transversalement aux parois latérales du coffre, à distance du plancher du coffre, derrière les dossiers des sièges de dernier rang, de manière à permettre le déploiement du rideau sensiblement horizontalement au dessus du coffre. Un système d'accrochage du bord libre du rideau sur les parois latérales du coffre, du côté de l'ouverture du coffre, permet de maintenir le rideau déployé au dessus du coffre.  Some long boxes, especially hatchbacks, have a tendelet to hide the contents of the trunk when the latter is closed. The tendelet consists of a flexible curtain mounted on a reel housed in a rigid housing. The tendelet is fixed transversely to the side walls of the trunk, away from the floor of the trunk, behind the backs of the seats of last row, so as to allow the deployment of the curtain substantially horizontally above the trunk. A fastening system of the free edge of the curtain on the side walls of the trunk, on the side of the trunk opening, keeps the curtain deployed above the trunk.
Pour la sécurité des passagers en cas d'accident, le tendelet, en particulier le boîtier du tendelet, est généralement verrouillé aux parois latérales du coffre lorsqu'il est monté dans le coffre. Dans cette position d'utilisation, le tendelet est alors situé au dessus du plancher du coffre, généralement au niveau du haut des dossiers des sièges.  For passenger safety in the event of an accident, the tendelet, in particular the tendelet casing, is generally locked to the side walls of the boot when it is mounted in the boot. In this position of use, the tendelet is then located above the floor of the trunk, usually at the top of the seat backs.
Il est également avantageux de prévoir un démontage complet du tendelet, notamment lorsque des objets encombrants doivent être chargés dans le coffre. A cet effet, le tendelet est généralement déverrouillé puis éventuellement rangé dans un logement prévu à cet effet sous le plancher du coffre. Ce rangement doit être effectué manuellement, l'utilisateur devant porter le tendelet de sa position d'utilisation jusqu'à sa position de rangement à l'intérieur du logement situé sous le plancher. Cette manipulation peut s'avérer relativement délicate compte tenu des dimensions du tendelet.  It is also advantageous to provide complete disassembly of the tendelet, especially when bulky objects have to be loaded into the trunk. For this purpose, the tendelet is generally unlocked and optionally stored in a housing provided for this purpose under the floor of the trunk. This storage must be done manually, the user having to wear the tendelet from its use position to its storage position inside the housing located under the floor. This manipulation can be relatively delicate given the size of the tendelet.
L'invention vise à pallier ces inconvénients en proposant un agencement de coffre pour véhicule automobile permettant un déplacement facile du tendelet entre sa position d'utilisation et sa position de rangement.  The invention aims to overcome these disadvantages by providing a trunk arrangement for a motor vehicle for easy movement of the tendelet between its use position and its storage position.
A cet effet, l'objet de l'invention concerne un agencement d'un coffre pour véhicule automobile, ledit coffre étant délimité par un plancher et deux parois latérales et comprenant un tendelet formé d'un boîtier supportant un rideau s 'étendant au-dessus du plancher du coffre entre les deux parois latérales, ledit rideau étant rétractable à l'intérieur du boîtier par enroulement autour d'un enrouleur logé à l'intérieur dudit boîtier, le plancher étant pourvu d'un logement agencé pour recevoir le tendelet lorsque le rideau est rétracté, caractérisé en ce que l'agencement de coffre comprend des moyens de translation du tendelet entre une position haute d'utilisation située au dessus du plancher du coffre et une position basse de rangement dans laquelle le tendelet est logé à l'intérieur du logement du plancher, ces moyens de translation comprenant, sur chaque bord latéral du tendelet, un système à pignon crémaillère associé d'une part à des moyens de guidage du tendelet et d'autre part à des moyens de blocage du tendelet au moins dans sa position haute d'utilisation. To this end, the object of the invention relates to an arrangement of a trunk for a motor vehicle, said trunk being delimited by a floor and two side walls and comprising a tendelet formed of a housing supporting a curtain extending beyond above the floor of trunk between the two side walls, said curtain being retractable inside the housing by winding around a reel housed inside said housing, the floor being provided with a housing arranged to receive the tendelet when the curtain is retracted , characterized in that the trunk arrangement comprises translational means of the tendelet between a high position of use located above the floor of the trunk and a low storage position in which the tendelet is housed inside the housing of the floor, these translational means comprising, on each lateral edge of the tendelet, a pinion rack system associated on the one hand with guide means of the tendelet and on the other hand with means for locking the tendelet at least in its up position use.
L'utilisateur peut ainsi déplacer le tendelet entre ses positions d'utilisation et de rangement facilement, sans avoir à positionner manuellement le tendelet.  The user can thus move the tendelet between its use and storage positions easily, without having to manually position the tendelet.
Avantageusement et de manière non limitative, pour chaque système à pignon crémaillère, un élément formant crémaillère est positionné sur la face interne d'une branche latérale d'un profilé en forme de U dont l'ouverture est dirigée vers l'intérieur du véhicule.  Advantageously and in a nonlimiting manner, for each rack-and-pinion system, a rack-and-pinion element is positioned on the internal face of a lateral branch of a U-shaped section whose opening is directed towards the inside of the vehicle.
En particulier, les profilés des deux systèmes à pignon crémaillère peuvent être fixés chacun sur une paroi latérale du coffre, en regard l'un de l'autre. Chaque profilé pourra être fixé sur la face visible de la paroi latérale, ou sur sa face opposée invisible, une fente étant alors réalisée au travers de la paroi latérale en regard de l'ouverture du profilé, permettant l'accès à ce dernier.  In particular, the profiles of the two rack-and-pinion systems can each be fixed on a side wall of the box, facing one another. Each section may be fixed on the visible face of the side wall, or on its opposite invisible face, a slot being then formed through the side wall facing the opening of the profile, allowing access to the latter.
Avantageusement et de manière non limitative, le profilé peut être une pièce métallique, par exemple en aluminium. Il est alors fixé par des vis, rivets ou analogue sur la paroi latérale. Le profilé peut également être une pièce en matière polymère rigide. Le matériau polymère utilisé peut être un polypropylène, chargé ou non, présentant une rigidité suffisante pour ne pas se déformer aux températures d'utilisation, qui peuvent être comprises de -30°C à + 100°C. Le profilé peut par exemple être intégré à la paroi latérale, notamment être réalisé d'une pièce avec la paroi latérale, cette dernière étant en matière polymère rigide du type de celles précitées. Chaque profilé peut être fixé, ou faire partie, d'une partie de paroi latérale située le long d'une ouverture de porte et formant une partie d'un encadrement de porte. Advantageously and without limitation, the section may be a metal part, for example aluminum. It is then fixed by screws, rivets or the like on the side wall. The profile may also be a piece of rigid polymeric material. The polymeric material used may be a polypropylene, filled or unloaded, having sufficient rigidity not to deform at operating temperatures, which may range from -30 ° C to + 100 ° C. The profile may for example be integrated in the side wall, in particular be made in one piece with the side wall, the latter being rigid polymeric material of the type mentioned above. Each profile may be attached, or be part of, a sidewall portion located along a door opening and forming part of a door frame.
Plus particulièrement, chaque profilé peut être partiellement fermé de manière à définir une rainure en forme de « C » dont l'ouverture dirigée vers l'intérieur du véhicule est traversée par un axe supportant un pignon du système à pignon crémaillère, le profilé étant agencé de manière à bloquer une translation du pignon parallèlement à son axe de rotation. Ceci permet notamment un positionnement correct du tendelet par rapport aux moyens de translation.  More particularly, each section may be partially closed so as to define a "C" -shaped groove whose opening directed towards the interior of the vehicle is traversed by an axis supporting a pinion of the rack-and-pinion system, the profile being arranged so as to block a translation of the pinion parallel to its axis of rotation. This allows in particular a correct positioning of the tendelet with respect to the translation means.
Avantageusement et de manière non limitative, les pignons du système à pignon crémaillère peuvent être montés sur le tendelet, leurs axes étant confondus et s'étendant parallèlement à l'axe de l'enrouleur du tendelet.  Advantageously and in a non-limiting manner, the pinions of the rack-and-pinion system can be mounted on the tendelet, their axes being merged and extending parallel to the axis of the reel of the tendelet.
La rotation des pignons peut également être libre par rapport au tendelet, notamment dans le cas d'un système à pignon crémaillère non motorisé : le tendelet se déplace de sa position d'utilisation à sa position de rangement sous l'effet de son propre poids, le mouvement inverse étant obtenu en soulevant le tendelet manuellement de sa position de rangement à sa position d'utilisation.  The rotation of the pinions can also be free with respect to the tendelet, in particular in the case of a non-motorized rack-and-pinion system: the tendelet moves from its position of use to its storage position under the effect of its own weight. , the reverse movement being obtained by lifting the tendelet manually from its storage position to its position of use.
La rotation des pignons peut être partiellement libre par rapport au tendelet : des moyens élastiques peuvent être agencés entre les axes des pignons et le tendelet, ou entre le tendelet et au moins une des deux parois latérales pour ralentir le déplacement du tendelet de sa position d'utilisation à sa position de rangement et faciliter le déplacement inverse du tendelet, par exemple en exerçant une force de rappel de sa position de rangement vers sa position d'utilisation. Il peut s'agir par exemple d'un système de ressorts hélicoïdaux disposés autour des axes des pignons, dont une extrémité est solidaire des pignons et dont l'autre extrémité est solidaire du tendelet.  The rotation of the pinions may be partially free with respect to the tendelet: elastic means may be arranged between the axes of the gables and the tendelet, or between the tendelet and at least one of the two side walls to slow the movement of the tendelet from its position use in its storage position and facilitate the reverse movement of the tendelet, for example by exerting a restoring force from its storage position to its position of use. It may be for example a system of helical springs arranged around the axes of the gears, one end of which is secured to the gears and whose other end is integral with the tendelet.
En variante, la rotation des pignons peut être commandée par un ou plusieurs moteurs permettant ainsi une descente et une remontée automatisée du tendelet. Le ou les moteurs sont par exemple logés à l'intérieur du boîtier du tendelet.  Alternatively, the rotation of the pinions can be controlled by one or more motors thus allowing a descent and automated lift of the tendelet. The motor or motors are for example housed inside the housing of the tendelet.
Dans ces différentes variantes, les pignons peuvent être avantageusement solidaires des extrémités d'un axe monté sur le tendelet et qui s'étend parallèlement à l'axe de l'enrouleur du tendelet. Ceci permet de synchroniser le mouvement des deux pignons. En particulier, pour un gain de place, l'axe supportant les pignons peut être logé à l'intérieur de l'enrouleur du tendelet. In these different variants, the pinions can be advantageously secured to the ends of an axis mounted on the tendelet and which extends parallel to the axis of the winder of the tendelet. This synchronizes the movement of the two gears. In particular, to save space, the axis supporting the pinions can be housed inside the winder of the tendelet.
Dans une autre variante, les pignons peuvent être fixes par rapport au tendelet, la montée et la descente du tendelet pouvant alors être obtenue par une translation motorisée de l'élément formant crémaillère ou par une rotation motorisée de cet élément formant crémaillère, lequel peut alors être une vis sans fin. Le ou les moteurs peuvent alors être logés à l'intérieur de l'habitacle du véhicule automobile équipé de l'agencement de coffre selon l'invention, par exemple derrière les parois latérales ou sous le plancher du véhicule. Dans ce cas, les pignons peuvent être montés fixes directement sur le tendelet ou éventuellement être montés aux extrémités d'un axe monté fixe sur le tendelet et s 'étendant parallèlement à l'axe de l'enrouleur du tendelet, par exemple logé à l'intérieur de l'enrouleur.  In another variant, the pinions may be fixed relative to the tendelet, the rise and fall of the tendelet can then be obtained by a motorized translation of the rack member or by a motorized rotation of the rack member, which can then to be a worm. The engine (s) can then be housed inside the passenger compartment of the motor vehicle equipped with the boot arrangement according to the invention, for example behind the side walls or under the floor of the vehicle. In this case, the pinions can be mounted fixed directly on the tendelet or possibly be mounted at the ends of a fixed axle mounted on the tendelet and extending parallel to the axis of the winder of the tendelet, for example housed in the inside the winder.
Lorsque le système à pignon crémaillère est motorisé, le ou les moteurs peuvent être commandés par un organe de commande électrique, de type bouton. Dans ce cas, notamment lorsque le rangement du plancher est fermé par une trappe, il peut être avantageux de prévoir une ouverture automatisée de la trappe, coordonnée au déplacement du tendelet. Cette ouverture automatisée peut par exemple être obtenue par un ou plusieurs vérins. Le ou les moteurs et le ou les vérins peuvent alors être reliés à un dispositif de gestion, comprenant, ou intégré à, un processeur, par exemple un microcontrôleur, un micro processeur, ou autre. Ce dispositif de gestion peut comprendre un produit de programme, notamment utilisé et exécuté par le dispositif de gestion, ce produit de programme comprenant un support d'enregistrement lisible par le processeur sur lequel est enregistré un programme lequel amène le processeur à coordonner les mouvements du tendelet et de la trappe fermant le logement.  When the rack-and-pinion system is motorized, the motor or motors can be controlled by an electric control member, of the button type. In this case, especially when the storage of the floor is closed by a hatch, it may be advantageous to provide an automated opening of the hatch, coordinated to the movement of the tendelet. This automated opening can for example be obtained by one or more cylinders. The motor (s) and the jack (s) can then be connected to a management device, comprising, or integrated with, a processor, for example a microcontroller, a microprocessor, or the like. This management device may comprise a program product, in particular used and executed by the management device, this program product comprising a processor-readable recording medium on which is recorded a program which causes the processor to coordinate the movements of the program. tendelet and hatch closing housing.
Avantageusement et de manière non limitative, les moyens de blocage peuvent comprendre, pour chaque système pignon crémaillère, un doigt porté par une paroi latérale, ledit doigt étant déplaçable par un organe de commande entre une position escamotée autorisant le déplacement du tendelet entre lesdites position d'utilisation et de rangement, et une position de verrouillage du tendelet au moins en position haute d'utilisation dans laquelle il coopère avec un orifice ménagé à une extrémité du boîtier du tendelet. Advantageously and in a nonlimiting manner, the locking means may comprise, for each pinion rack system, a finger carried by a side wall, said finger being movable by a control member between a retracted position allowing the movement of the tendelet between said position use and storage, and a latch position of the tendelet at least in high position of use in which it cooperates with an orifice at one end of the tendelet housing.
Ce doigt de blocage peut s'étendre sensiblement perpendiculairement à l'axe de l'enrouleur du tendelet, par exemple sensiblement parallèlement au plancher.  This locking finger may extend substantially perpendicular to the axis of the winding of the tendelet, for example substantially parallel to the floor.
L'organe de commande peut être un organe mécanique, par exemple un bouton à presser ou tourner. L'organe de commande peut également être un organe électrique ou électromécanique alimentant ou commandant un moyen de commande du déplacement du doigt escamotable.  The control member may be a mechanical member, for example a button to be pressed or turned. The control member may also be an electrical or electromechanical member supplying or controlling a means for controlling the movement of the retractable finger.
Avantageusement et de manière non limitative, les moyens de blocage peuvent en outre comprendre un élément de blocage solidaire de la paroi latérale, situé à distance du doigt escamotable dans la direction de translation du tendelet, agencé de manière à exercer une pression sur le tendelet en direction du doigt escamotable, parallèlement à la direction de translation. Ceci permet notamment de limiter les vibrations du tendelet lorsque le véhicule roule, ce qui permet ainsi de réduire les bruits.  Advantageously and in a nonlimiting manner, the locking means may further comprise a blocking element integral with the side wall, situated at a distance from the retractable finger in the direction of translation of the tendelet, arranged so as to exert pressure on the tendelet in direction of the retractable finger, parallel to the direction of translation. This allows in particular to limit the vibrations of the tendelet when the vehicle rolls, which thus reduces noise.
Cet élément de blocage peut comporter, ou être constitué par, une butée en matière élastomère en appui contre le tendelet. Il peut être réalisé entièrement en matière polymère de type élastomère, ou comporter une partie en matière polymère rigide et une partie en matière élastomère assurant la fonction de butée. Notamment, cet élément de blocage peut être relié à la paroi latérale, éventuellement par une charnière film lorsque la paroi latérale est en matériau polymère.  This locking element may comprise or be constituted by a stop made of elastomeric material bearing against the tendelet. It may be made entirely of elastomeric polymer material, or comprise a rigid polymeric material part and an elastomeric material part providing the stop function. In particular, this locking element may be connected to the side wall, possibly by a film hinge when the side wall is made of polymer material.
Avantageusement et de manière non limitative, cet élément de blocage peut fermer le haut d'un profilé en forme de U ou de C recevant l'élément formant crémaillère à l'intérieur de sa rainure. Ceci permet d'éviter que les pignons du système à pignons crémaillère ne sortent par accident hors de la rainure du profilé, notamment lorsque le tendelet est remonté de sa position de rangement vers sa position d'utilisation. Cet élément de blocage peut alors être avantageusement amovible ou escamotable afin de permettre un démontage complet du tendelet.  Advantageously and in a nonlimiting manner, this locking element can close the top of a U-shaped section or C receiving the rack member within its groove. This makes it possible to prevent the pinions of the rack-and-pinion system from accidentally coming out of the groove of the profile, particularly when the tendelet is raised from its storage position to its position of use. This locking element can then be advantageously removable or retractable to allow complete disassembly of the tendelet.
En variante, le démontage du tendelet peut être rendu possible par la réalisation de fentes dans chaque profilé, perpendiculairement à la direction de translation du tendelet, ces fentes étant suffisantes pour permettre le passage des pignons et pouvant être obturées par un élément de fermeture amovible ou escamotable. Alternatively, the dismantling of the tendelet can be made possible by the production of slots in each profile, perpendicular to the direction of translation of the tendelet, these slots being sufficient for allow the passage of gables and can be closed by a removable or retractable closure element.
Dans un tendelet, un bord libre du rideau reste en général toujours en dehors du boîtier afin de permettre la préhension du rideau. En outre, ce bord libre supporte généralement les moyens de fixation du rideau aux parois latérales lorsque le rideau s'étend au dessus du coffre. A cet effet, les extrémités latérales du tendelet sont généralement rigidifiées, par exemple par des parties en matière polymère rigide, qui ne peuvent être rétractées à l'intérieur du boîtier. Ces parties rigides alourdissent le bord avant du rideau, lequel peut se détériorer s'il n'est pas maintenu.  In a tendelet, a free edge of the curtain is usually always outside the housing to allow the gripping of the curtain. In addition, this free edge generally supports the means for fixing the curtain to the side walls when the curtain extends above the trunk. For this purpose, the lateral ends of the tendelet are generally stiffened, for example by rigid polymer material parts, which can not be retracted inside the housing. These rigid parts weigh down the front edge of the curtain, which can deteriorate if it is not maintained.
Avantageusement et de manière non limitative, le tendelet peut comprendre à chaque extrémité latérale du bord libre du rideau au moins un doigt de blocage saillant du rideau du tendelet parallèlement à l'axe de l'enrouleur, une rainure formée sur chaque paroi latérale parallèlement à la direction de translation recevant ledit doigt de blocage lors du déplacement du tendelet entre ses positions d'utilisation et de rangement. Une patte de support escamotable portée par une paroi latérale peut alors fermer l'extrémité supérieure de ladite rainure, ladite patte étant déplaçable par un organe de commande entre une position escamotée pour le déplacement du tendelet entre lesdites position d'utilisation et de rangement, et une position de support dans laquelle elle supporte ledit doigt de blocage lorsque le tendelet est en position d'utilisation.  Advantageously and in a nonlimiting manner, the tendelet may comprise at each lateral end of the free edge of the curtain at least one locking pin protruding from the curtain of the tendelet parallel to the axis of the winder, a groove formed on each side wall parallel to the translation direction receiving said locking finger during movement of the tendelet between its use and storage positions. A retractable support lug carried by a side wall can then close the upper end of said groove, said lug being movable by a control member between a retracted position for moving the tendelet between said position of use and storage, and a support position in which it supports said locking finger when the tendelet is in the use position.
Ceci permet de maintenir le bord libre du rideau lorsque le tendelet est en position d'utilisation, le rideau étant rétracté, sans gêner le mouvement du tendelet entre ses positions d'utilisation et de rangement. Ceci peut notamment éviter que le rideau ne soit détérioré et peut également faciliter sa préhension. En particulier, la patte de support peut être agencée de manière à ce que le bord libre du rideau soit maintenu sensiblement horizontalement.  This keeps the free edge of the curtain when the tendelet is in the use position, the curtain being retracted, without hindering the movement of the tendelet between its use and storage positions. This can in particular prevent the curtain from being damaged and can also facilitate its grip. In particular, the support lug may be arranged so that the free edge of the curtain is maintained substantially horizontally.
L'organe de commande peut être le même que celui qui commande les moyens de blocage décrits précédemment.  The control member may be the same as that which controls the locking means described above.
Le doigt de blocage du rideau décrit ci-dessus peut avantageusement servir au blocage du rideau dans une position dans laquelle il est déployé au dessus du plancher. Ce doigt de blocage peut alors être en prise avec un orifice correspondant de la paroi latérale, à proximité de l'ouverture du coffre. The curtain locking finger described above can advantageously be used to lock the curtain in a position in which it is deployed above the floor. This blocking finger can then be engaged with a corresponding hole of the side wall, near the opening of the trunk.
Avantageusement et de manière non limitative, les moyens de guidage du tendelet associés à chaque système à pignon crémaillère comprennent au moins deux surfaces de guidage parallèles à la direction de translation du tendelet et solidaires du système à pignon crémaillère et au moins une patte de guidage solidaire du tendelet et située entre lesdites surfaces de guidage, en contact avec celles-ci. Ceci permet d'éviter que le tendelet ne pivote autour de l'axe des pignons lors de son déplacement entre ses positions d'utilisation et de rangement.  Advantageously and in a nonlimiting manner, the guide means of the tendelet associated with each rack and pinion system comprise at least two guide surfaces parallel to the direction of translation of the tendelet and integral with the rack and pinion system and at least one integral guiding tab. of the tendelet and located between said guide surfaces in contact therewith. This makes it possible to prevent the tendelet from pivoting about the axis of the gears when it moves between its positions of use and storage.
Avantageusement, ces surfaces de guidage peuvent être solidaires des parois latérales de part et d'autre de l'élément formant crémaillère du système à pignon crémaillère ou encore faire partie du profilé recevant l'élément formant crémaillère du système à pignon crémaillère. Le tendelet peut être pourvu de deux pattes de guidage coopérant chacune avec une surface de guidage et disposées de part et d'autre de l'axe du pignon, entre le pignon et le boîtier du tendelet supportant le pignon. Ceci permet une réalisation compacte de l'extrémité latérale du tendelet, sans augmenter sa dimension suivant l'axe de l'enrouleur.  Advantageously, these guide surfaces may be secured to the side walls on either side of the rack member of the rack pinion system or be part of the profile receiving the rack member of rack pinion system. The tendelet may be provided with two guide lugs each cooperating with a guide surface and disposed on either side of the axis of the pinion, between the pinion and the housing of the tendelet supporting the pinion. This allows a compact realization of the lateral end of the tendelet, without increasing its dimension along the axis of the winder.
L'invention concerne également un véhicule automobile, comprenant un agencement de coffre tel que décrit ci-dessus.  The invention also relates to a motor vehicle, comprising a trunk arrangement as described above.

Dans la présente description, les termes avant, arrière, supérieur, inférieur, font référence aux directions avant et arrière du véhicule. Les axes X, Y, Z, correspondent respectivement à l'axe longitudinal (d'avant en arrière), transversal et vertical du véhicule. In the present description, the terms front, rear, upper, lower, refer to the front and rear directions of the vehicle. The axes X, Y, Z, respectively correspond to the longitudinal (front to back), transverse and vertical axis of the vehicle.
Par sensiblement horizontal, longitudinal ou vertical, on entend une direction/un plan formant un angle d'au plus ±20°, voire d'au plus ±10° avec une direction/un plan horizontal, longitudinal ou vertical.  By substantially horizontal, longitudinal or vertical means a direction / a plane forming an angle of at most ± 20 °, or even at most ± 10 ° with a direction / a horizontal, longitudinal or vertical plane.
Les figures 1 et 2 représentent partiellement une partie arrière d'un véhicule automobile désigné dans son ensemble par la référence 1. Cette partie arrière comporte un coffre 2 délimité dans sa partie inférieure par un plancher 3 et latéralement par des parois latérales 4 (dont une seule est représentée sur les figures 1 et 2). FIGS. 1 and 2 partially represent a rear part of a motor vehicle generally designated by the reference 1. This rear part comprises a box 2 delimited in its lower part by a floor 3 and laterally by side walls 4 (one of which only one is shown in Figures 1 and 2).
Longitudinalement, le coffre est en outre limité de manière classique par une porte fermant l'ouverture du coffre à l'arrière du véhicule (non représentée) et par l'arrière des sièges 5 de dernier rang (représentés figure 2 uniquement pour plus de clarté). Longitudinalement, the trunk is further limited conventionally by a door closing the opening of the trunk at the rear of the vehicle (not shown) and the rear seats 5 of last rank (shown in Figure 2 only for clarity ).
Dans l'exemple représenté, le plancher 3 est formé d'une structure de plancher 3a assurant la rigidité du plancher, généralement en tôle, cette structure 3a étant recouverte d'un faux plancher 3b, formé par exemple d'une moquette épaisse. L'invention n'est nullement limitée à la forme du plancher 3 décrite ci-dessus. En particulier, la structure 3a et le faux plancher 3b peuvent former une seule et unique pièce.  In the example shown, the floor 3 is formed of a floor structure 3a ensuring the rigidity of the floor, usually sheet metal, this structure 3a is covered with a false floor 3b, formed for example of a thick carpet. The invention is not limited to the shape of the floor 3 described above. In particular, the structure 3a and the false floor 3b can form a single piece.
Dans l'exemple représenté, chaque paroi latérale 4 est en outre formée de plusieurs parties, une première partie 4' en tôle, qui sera habillée ensuite par une garniture non représentée, une deuxième partie 4" située à l'avant du coffre et formant une partie d'un encadrement de porte, cette deuxième partie 4" peut être en matière polymère réalisée par injection, et une troisième partie 4"' située au dessus des première et deuxième parties, appelée souvent garniture de tablette. Cette troisième partie 4"' peut également être réalisée en matière polymère, injectée ou moulée, et supporte le tendelet 10 dans sa position d'utilisation. Bien entendu, l'invention n'est pas limitée à la forme de la paroi latérale décrite ci-dessus.  In the example shown, each side wall 4 is furthermore formed of several parts, a first part 4 'made of sheet metal, which will then be dressed with a not shown gasket, a second part 4 "located at the front of the trunk and forming part of a door frame, this second part 4 "may be made of polymer material made by injection, and a third part 4" 'located above the first and second parts, often called tablet pad. may also be made of polymeric material, injected or molded, and supports the tendelet 10 in its position of use. Of course, the invention is not limited to the shape of the side wall described above.
Afin de cacher le contenu du coffre 2 des regards indiscrets, ce coffre comporte un tendelet 10 formé d'un boîtier 1 1 supportant un rideau 12 s'étendant au-dessus du plancher 3 du coffre entre les deux parois latérales 4. Le rideau 12 est dans une matière souple permettant de l'enrouler autour d'un enrouleur 13 (visible partiellement figure 4), logé à l'intérieur du boîtier 1 1. A cet effet, le rideau 12 est généralement en textile, mais peut être également formé d'une feuille souple de matériau polymère ou de tout autre matériau adapté. Le rideau 12 est ainsi rétractable à l'intérieur du boîtier 1 1 par enroulement autour de l'enrouleur 13 d'axe 13a. In order to hide the contents of the trunk 2 prying eyes, this trunk has a tendelet 10 formed of a housing 1 1 supporting a curtain 12 extending above the floor 3 of the trunk between the two side walls 4. The curtain 12 is in a flexible material for wrapping around a reel 13 (partially visible Figure 4), housed inside the housing 1 1. For this purpose, the curtain 12 is generally in textile, but may also be formed of a flexible sheet of polymeric material or any other suitable material. The curtain 12 is thus retractable inside the casing 1 1 by winding around the reel 13 axis 13a.
Le plancher 3 est pourvu d'un logement 6 agencé pour recevoir le tendelet 10 lorsque le rideau 12 est rétracté, tel que représenté sur la figure 2. Dans l'exemple, la structure 3a du plancher est agencée pour former ce logement 6, lequel est situé sous le faux plancher 3b. Ce dernier peut être replié tel que visible sur la figure 2 pour permettre l'accès au logement 6. En variante, une trappe indépendante du faux plancher 3b peut être prévue pour fermer ce logement 6. Tel que visible sur la figure 2, le logement 6 est dimensionné pour accueillir le boîtier 1 1 du tendelet 10 alors que le rideau 12 est rétracté à l'intérieur du boîtier 1 1. Le bord avant libre 12a du rideau 12, lequel ne peut être rétracté à l'intérieur du boîtier 1 1 , repose alors à plat sur la structure The floor 3 is provided with a housing 6 arranged to receive the tendelet 10 when the curtain 12 is retracted, as shown in Figure 2. In the example, the structure 3a of the floor is arranged to form the housing 6, which is located under the false floor 3b. The latter can be folded as shown in Figure 2 to allow access to the housing 6. Alternatively, an independent hatch false floor 3b can be provided to close the housing 6. As shown in Figure 2, housing 6 is dimensioned to receive the housing 1 1 of the tendelet 10 while the curtain 12 is retracted inside the housing 1 1. The free front edge 12a of the curtain 12, which can not be retracted inside the housing 1 1 , then lie flat on the structure
3a du plancher 3, en dehors du logement 6. 3a of floor 3, outside housing 6.
Afin de faciliter le déplacement du tendelet 10 entre une position haute d'utilisation située au dessus du plancher 3 du coffre (figure 1) et une position basse de rangement dans laquelle le tendelet 10 est logé à l'intérieur du logement 6 du plancher 3 (figure 2), le coffre 2 est agencé selon l'invention et comporte, à cet effet, des moyens de translation 7 associés au tendelet 10 qui permettent de le déplacer entre ladite position haute d'utilisation et ladite position basse de rangement.  To facilitate the movement of the tendelet 10 between a high use position located above the floor 3 of the trunk (Figure 1) and a low storage position in which the tendelet 10 is housed inside the housing 6 of the floor 3 (Figure 2), the trunk 2 is arranged according to the invention and comprises, for this purpose, translation means 7 associated with the tendelet 10 which allow to move between said upper position of use and said low storage position.
Ces moyens de translation 7 comprennent, sur chaque bord latéral 10a du tendelet 10, un système à pignon crémaillère 20 These translation means 7 comprise, on each lateral edge 10a of the tendelet 10, a rack and pinion system 20
(représenté en détail sur la figure 4) associé d'une part à des moyens de guidage 30 du tendelet (représentés figures 3 et 4) et d'autre part à des moyens de blocage 40 du tendelet (représentés sur la figure 5) au moins dans sa position haute d'utilisation. (shown in detail in FIG. 4) associated on the one hand with guide means 30 of the tendelet (shown in FIGS. 3 and 4) and on the other hand with locking means 40 of the tendelet (shown in FIG. less in its high position of use.
Les deux systèmes à pignon crémaillère 20 étant identiques et symétriques, un seul système 20 sera décrit. Ces systèmes à pignon crémaillère 20 sont disposés de manière à permettre une translation du tendelet 10 suivant une direction sensiblement verticale.  Since both rack and pinion systems 20 are identical and symmetrical, only one system 20 will be described. These rack pinion systems 20 are arranged to allow a translation of the tendelet 10 in a substantially vertical direction.
Tel que visible sur la figure 4, le système à pignon crémaillère 20 est formé d'un élément formant crémaillère 21 et d'un pignon 22 coopérant avec cet élément formant crémaillère 21. Les pignons 22 sont montés sur le tendelet 10, leurs axes 22b étant confondus avec l'axe 13a de l'enrouleur 13 du tendelet. Dans l'exemple représenté, les pignons 22 sont solidaires en rotation d'un axe 24, lequel est logé à l'intérieur de l'enrouleur 13, libre à rotation par rapport à ce dernier (ou partiellement libre). As can be seen in FIG. 4, the rack pinion system 20 is formed of a rack member 21 and a pinion 22 cooperating with this rack member 21. The pinions 22 are mounted on the tendelet 10, their axes 22b coinciding with the axis 13a of the reel 13 of the tendelet. In the example shown, the pinions 22 are integral in rotation with an axis 24, which is housed inside the reel 13, free to rotate relative to the latter (or partially free).
L'élément formant crémaillère 21 est positionné sur la face interne d'une branche latérale 23a d'un profilé 23 en forme de « U », dont l'ouverture est dirigée vers l'intérieur du véhicule automobile. Les profilés 23 des deux systèmes à pignon crémaillère 20 sont fixés chacun sur une paroi latérale 4 du coffre, en regard l'un de l'autre. Ils s'étendent entre les positions d'utilisation et de rangement du tendelet 10, à savoir suivant une direction sensiblement verticale.  The rack member 21 is positioned on the inner face of a side branch 23a of a U-shaped profile 23, whose opening is directed towards the inside of the motor vehicle. The profiles 23 of the two pinion rack systems 20 are each fixed on a side wall 4 of the box, facing one another. They extend between the positions of use and storage of the tendelet 10, namely in a substantially vertical direction.
Le profilé 23 comporte ainsi une âme 23b reliée à deux branches latérales 23a sur l'une desquelles est monté l'élément formant crémaillère 21. Dans l'exemple, cet élément formant crémaillère 21 est une crémaillère rectiligne dont les dents 21a sont situées en regard de la branche latérale 23a opposée. L'âme 23b et les branches latérales 23a définissent un logement 23c à l'intérieur duquel se déplace le pignon 22, dont les dents 22a sont en prise avec les dents 21a de l'élément formant crémaillère 21. Ce logement 23c peut être partiellement fermé par des parois latérales 23d, situées en regard de l'âme 23b, parallèlement à celle-ci, et entre lesquelles passe l'axe 24 portant le pignon 22, cet axe 24 s'étendant sensiblement horizontalement et perpendiculairement à l'âme 23b. Le profilé 23 présente ainsi un profil en forme de « C ». En outre, le profilé 23 est agencé de manière à bloquer une translation du pignon 22 parallèlement à son axe de rotation 22b.  The profile 23 thus comprises a core 23b connected to two lateral branches 23a on one of which is mounted the rack member 21. In the example, this rack member 21 is a rectilinear rack whose teeth 21a are located opposite of the opposite side branch 23a. The core 23b and the lateral branches 23a define a housing 23c inside which the pinion 22 moves, whose teeth 22a are engaged with the teeth 21a of the rack member 21. This housing 23c can be partially closed by 23d side walls, located opposite the core 23b, parallel thereto, and between which passes the axis 24 carrying the pinion 22, the axis 24 extending substantially horizontally and perpendicular to the core 23b. The section 23 thus has a profile in the shape of "C". In addition, the profile 23 is arranged to block a translation of the pinion 22 parallel to its axis of rotation 22b.
Le profilé 23 est fixé sur la paroi latérale 4 du coffre. Dans l'exemple, le profilé 23 est fixé sur la face invisible 4a de la paroi latérale 4, opposée à la face visible 4b depuis l'habitacle. A cet effet, les parois latérales 23d du profilé 23 peuvent saillir de part et d'autre des parois latérales 23a pour permettre la fixation du profilé 23 sur la face invisible 4a de la paroi latérale 4 (figure 4). Afin de permettre l'accès à l'ouverture du profilé 23, la paroi latérale 4 est pourvue d'une fente 4c (figures 3 et 4).  The section 23 is fixed on the side wall 4 of the trunk. In the example, the section 23 is fixed on the invisible face 4a of the side wall 4, opposite to the visible face 4b from the passenger compartment. For this purpose, the side walls 23d of the profile 23 may protrude on either side of the side walls 23a to allow the attachment of the profile 23 on the invisible face 4a of the side wall 4 (Figure 4). To allow access to the opening of the profile 23, the side wall 4 is provided with a slot 4c (Figures 3 and 4).
Les moyens de guidage 30 du tendelet associés à chaque système pignon crémaillère sont décrits en référence aux figures 3 et 4. Ces moyens de guidage 30 comprennent deux surfaces de guidage 31 parallèles à la direction de translation du tendelet et solidaires du système pignon crémaillère 20 et deux pattes de guidage 32 solidaires du tendelet et situées entre lesdites surfaces de guidage 31 , en contact avec celles-ci. The tendelet guide means 30 associated with each rack and pinion system are described with reference to FIGS. 3 and 4. guide means 30 comprise two guide surfaces 31 parallel to the translational direction of the tendelet and integral with the rack and pinion system 20 and two guide lugs 32 integral with the tendelet and located between said guide surfaces 31, in contact therewith.
Dans l'exemple, ces surfaces de guidage 31 forment les bords de la fente 4c réalisée dans la paroi latérale 4 pour accéder à l'ouverture des profilés 23. Les pattes de guidage 32 sont quant à elles disposées de part et d'autre de l'axe 24 portant le pignon 22, entre le pignon 22 et le boîtier 1 1 du tendelet 10. Ces pattes de guidage 32, par leur contact avec les surfaces de guidage 31 assurent le guidage du tendelet 10 lors de ses déplacements et assurent également un bon positionnement du tendelet 10 par rapport au profilé 23.  In the example, these guide surfaces 31 form the edges of the slot 4c made in the side wall 4 to access the opening of the profiles 23. The guide tabs 32 are arranged on either side of the the pin 24 carrying the pinion 22, between the pinion 22 and the housing 1 1 of the tendelet 10. These guide tabs 32, by their contact with the guide surfaces 31 ensure the guidance of the tendelet 10 during its movements and also ensure a good positioning of the tendelet 10 relative to the profile 23.
Les moyens de blocage 40 auxquels sont associés les systèmes pignon crémaillère 20 comprennent, pour chaque système pignon crémaillère 20, un doigt 41 porté par une paroi latérale 4 et traversant le tendelet 10. Ce doigt 41 est déplaçable par un organe de commande 42 entre une position escamotée (non représentée) autorisant le déplacement du tendelet 10 entre lesdites positions d'utilisation et de rangement, et une position de verrouillage (figures 3 à 5) du tendelet 10 au moins en position haute d'utilisation dans laquelle il coopère avec un orifice 43 ménagé à une extrémité l ia du boîtier 1 1 du tendelet.  The locking means 40 to which the rack and pinion gear systems 20 are associated comprise, for each rack and pinion system 20, a finger 41 carried by a lateral wall 4 and passing through the sheet 10. This finger 41 can be displaced by a control member 42 between a retracted position (not shown) allowing the displacement of the tendelet 10 between said positions of use and storage, and a locking position (FIGS. 3 to 5) of the tendelet 10 at least in the upright position in which it co-operates with a port 43 formed at one end l ia of the housing 1 1 of the tendelet.
Dans l'exemple, ce doigt 41 est mobile en translation suivant une direction sensiblement horizontale et perpendiculaire à l'axe 13a de l'enrouleur, et peut être maintenu en position verrouillée par des moyens élastiques (ressort ou similaire), mécaniques (encliquetage) ou électromécanique (électroaimant). L'organe de commande 42 peut alors coopérer avec ces moyens pour commander le déplacement du doigt 41.  In the example, this finger 41 is movable in translation in a direction substantially horizontal and perpendicular to the axis 13a of the winder, and can be held in the locked position by elastic means (spring or the like), mechanical (latching) or electromechanical (electromagnet). The control member 42 can then cooperate with these means to control the movement of the finger 41.
Les moyens de blocage 40 peuvent en outre comprendre un élément de blocage 44 solidaire de la paroi latérale 4, situé à distance du doigt escamotable 41 dans la direction de translation du tendelet 10, agencé de manière à exercer une pression sur le tendelet 10 en direction du doigt escamotable 41 , parallèlement à la direction de translation. Cet élément de blocage 44 permet ainsi de bloquer tout mouvement du tendelet 10 suivant sa direction de déplacement. Dans l'exemple, cet élément de blocage 44 est une pièce rapportée qui ferme le sommet du logement 23c du profilé 23 dans lequel se déplace le pignon 22, et est agencé de manière à ce que son extrémité libre 44a soit en appui sur une face supérieure d'une extrémité latérale l ia du boîtier 1 1 du tendelet 10 (figure 5). The locking means 40 may further comprise a blocking element 44 integral with the lateral wall 4, situated at a distance from the retractable finger 41 in the direction of translation of the tendelet 10, arranged so as to exert pressure on the tendelet 10 in the direction retractable finger 41, parallel to the direction of translation. This blocking element 44 thus makes it possible to block any movement of the tendelet 10 along its direction of displacement. In the example, this locking element 44 is an insert which closes the top of the housing 23c of the profile 23 in which the pinion 22, and is arranged so that its free end 44a is supported on an upper face of a lateral end l ia of the housing 1 1 of the tendelet 10 (Figure 5).
L'élément de blocage 44 peut ainsi exercer avantageusement plusieurs fonctions :  The locking element 44 can thus advantageously exercise several functions:
une fermeture du logement 23c recevant le pignon 22, ce qui permet d'éviter une sortie accidentelle du pignon 22 hors de son logement 23c,  a closure of the housing 23c receiving the pinion 22, which prevents an accidental output of the pinion 22 out of its housing 23c,
un maintien du tendelet 10 en position d'utilisation, permettant notamment de limiter les vibrations et les bruits engendrés par ces vibrations lors du roulement du véhicule, et enfin  maintaining the tendelet 10 in the use position, in particular to limit the vibrations and noises generated by these vibrations during the rolling of the vehicle, and finally
un démontage du tendelet 10, lorsque cet élément de blocage 44 est fixé de manière amovible ou est escamotable.  disassembly of the tendelet 10, when the locking element 44 is removably attached or retractable.
Dans l'exemple représenté, le bord libre 12a du rideau 12 présente des moyens de fixation latéraux comportant par exemple au moins un doigt de blocage 12b saillant du rideau parallèlement à l'axe 13a de l'enrouleur (figure 3). Un tel doigt de blocage 12b coopère par exemple avec un logement correspondant 4d (figure 1) de la paroi latérale 4, à proximité de l'ouverture du coffre 2, pour maintenir le rideau 12 au dessus du plancher lorsque le tendelet 10 est en position d'utilisation et le rideau 12 est déployé.  In the example shown, the free edge 12a of the curtain 12 has lateral attachment means comprising for example at least one locking pin 12b protruding from the curtain parallel to the axis 13a of the winder (Figure 3). Such a locking pin 12b cooperates for example with a corresponding housing 4d (Figure 1) of the side wall 4, near the opening of the trunk 2, to maintain the curtain 12 above the floor when the tendelet 10 is in position of use and the curtain 12 is deployed.
Afin de permettre le déplacement du tendelet 10 entre ses positions d'utilisation et de rangement, le rideau 12 étant rétracté à l'intérieur du boîtier 1 1 , on forme alors une rainure 4e sur chaque paroi latérale 4 parallèlement à la direction de translation du tendelet 10, cette rainure 4e étant agencée pour recevoir ledit doigt de blocage 12b lors du déplacement du tendelet 10 entre ses positions d'utilisation et de rangement. Autrement dit, cette rainure 4e forme un couloir à l'intérieur duquel le doigt de blocage 12b peut être déplacé librement. In order to allow the displacement of the tendelet 10 between its positions of use and storage, the curtain 12 being retracted inside the casing 1 1, then a groove 4e is formed on each side wall 4 parallel to the direction of translation of the tendelet 10, this groove 4e being arranged to receive said locking finger 12b during the displacement of the tendelet 10 between its use and storage positions. In other words, this groove 4e forms a corridor within which the locking pin 12b can be moved freely.
Cette rainure 4e ne s'étend pas forcément sur toute la hauteur de la paroi latérale 4, mais s'étend sur une hauteur suffisante pour assurer un coulissement rideau 12 sans que le doigt de blocage 12b n'entre en collision avec la paroi latérale 4. This groove 4e does not necessarily extend over the entire height of the side wall 4, but extends over a height sufficient to ensure curtain sliding 12 without the locking pin 12b colliding with the side wall 4 .
Afin de permettre un support du bord libre 12a du rideau 12 alourdi par ces moyens de fixation, une patte de support 45 escamotable portée par la paroi latérale 4 ferme alors l'extrémité supérieure de ladite rainure 4e. La patte de support 45 est positionnée de manière à ce que, lorsque le doigt de blocage 12b du rideau 12 est supporté par cette patte de support 45, le bord libre 12a du rideau 12 s'étende sensiblement horizontalement. In order to allow support of the free edge 12a of the curtain 12 weighed down by these fastening means, a retractable support lug 45 carried by the side wall 4 then closes the end upper of said groove 4e. The support lug 45 is positioned so that, when the locking pin 12b of the curtain 12 is supported by this support lug 45, the free edge 12a of the curtain 12 extends substantially horizontally.
Dans l'exemple représenté, la patte de support 45 est solidaire du doigt de blocage 41 décrit plus haut et est agencée de manière à libérer le sommet de la rainure 4e lorsque le tendelet 10 est déverrouillé par actionnement de l'organe de commande 42. Cet organe de commande 42 permet alors d'une part de déplacer le doigt de blocage 41 du tendelet et d'autre part de déplacer la patte de support 45 entre une position escamotée autorisant le déplacement du tendelet entre lesdites positions d'utilisation et de rangement, et une position de support (figures 3-5) dans laquelle elle supporte ledit doigt de blocage 12b du tendelet 10 lorsque celui-ci est en position d'utilisation.  In the example shown, the support lug 45 is integral with the locking pin 41 described above and is arranged to release the top of the groove 4e when the tendon 10 is unlocked by actuation of the control member 42. This control member 42 then makes it possible on the one hand to move the locking pin 41 of the tendelet and on the other hand to move the support lug 45 between a retracted position allowing the movement of the tendelet between said positions of use and storage. and a support position (Figures 3-5) in which it supports said locking pin 12b of the tendelet 10 when the latter is in the use position.
Bien entendu, un organe de commande indépendant est envisageable pour la commande de la patte de support 45.  Of course, an independent control member can be envisaged for controlling the support lug 45.
La manipulation du tendelet 10 est maintenant décrite. Lorsque le tendelet 10 est dans la position d'utilisation représentée sur la figure 1 , dans laquelle le rideau 12 est rétracté à l'intérieur du boîtier 1 1 , les moyens de blocage 40 maintiennent le tendelet en position, la patte 41 étant insérée dans le logement 43 correspondant du boîtier 1 1 , la patte de support 45 supportant le doigt de blocage 12b du tendelet. Le rideau 12 peut être déployé en direction de l'ouverture du coffre 2, au dessus du plancher 3 et maintenu dans cette position par coopération de chaque doigt de blocage 12b avec le logement 4d correspondant de la paroi latérale 4. La préhension du rideau 12 dans la position représentée figure 1 est aisée du fait de la position sensiblement horizontale du bord avant 12a du rideau. Depuis la position représentée sur la figure 1 , le tendelet 10 peut également être amené dans son logement 6. A cet effet, l 'actionnement de l'organe de commande 42 permet de libérer le boîtier 1 1 du doigt de blocage 41 et de libérer le doigt de blocage 12b du tendelet de la patte de support 45. Le tendelet 10 est alors libre et peut coulisser suivant la direction de translation jusqu'au logement 6 par rotation des pignons 22 le long des éléments formant crémaillère 21. Une fois le tendelet 10 dans le logement 6 Handling of the tendelet 10 is now described. When the tendelet 10 is in the position of use shown in FIG. 1, in which the curtain 12 is retracted inside the casing 1 1, the locking means 40 hold the tendelet in position, the tab 41 being inserted into the corresponding housing 43 of the housing 1 1, the support lug 45 supporting the locking finger 12b of the tendelet. The curtain 12 can be deployed towards the opening of the trunk 2, above the floor 3 and held in this position by cooperation of each locking pin 12b with the corresponding housing 4d of the side wall 4. The gripping of the curtain 12 in the position shown in Figure 1 is easy because of the substantially horizontal position of the front edge 12a of the curtain. From the position shown in FIG. 1, the tendelet 10 can also be brought into its housing 6. For this purpose, the actuation of the control member 42 makes it possible to release the casing 1 1 from the locking finger 41 and to release the blocking finger 12b of the tendelet of the support lug 45. The tendelet 10 is then free and can slide in the direction of translation to the housing 6 by rotation of the gears 22 along the rack members 21. Once the tendelet 10 in dwelling 6
(figure 2), le faux plancher 3b peut être rabattu sur le tendelet 10, qui est ainsi protégé. La manipulation inverse permet de remonter le tendelet 10 dans la position de la figure 1. Dans cette position, enfin, le tendelet 10 peut ainsi être sorti du véhicule. A cet effet, les éléments de blocage 44 sont ôtés ou escamotés, ce qui permet, après actionnement de l'organe de commande 42 pour libérer le tendelet du doigt de blocage 41 , d'extraire les pignons 22 du logement 23c des profilés 23 en soulevant le tendelet 10. Ce dernier peut alors être ôté du véhicule. (Figure 2), the false floor 3b can be folded down on the tendelet 10, which is thus protected. The reverse manipulation makes it possible to raise the tendelet 10 in the position of FIG. 1. In this position, finally, the tendelet 10 can thus be taken out of the vehicle. For this purpose, the locking elements 44 are removed or retracted, which, after actuation of the control member 42 to release the tendon of the locking pin 41, to extract the pinions 22 of the housing 23c profiles 23 in lifting the tendelet 10. The latter can then be removed from the vehicle.
