Description

1 OUVRANT ARRI.ERE1 OPENING ARRIERE

La présente invention concerne un ouvrant arrière de véhicule automobile permettant, par prolongement du plancher du coffre dudit véhicule vers l'arrière au moyen d'un abattant inférieur adapté, d'augmenter les possibilités de chargement et de transport d'objets dans ledit coffre dudit véhicule, tout en préservant un accès facile à la totalité du volume dudit coffre lors des opérations de chargement, et, notamment, l'accès aux parties dudit coffre les plus proches des banquettes arrières dudit véhicule.  The present invention relates to a motor vehicle rear opening allowing, by extension of the floor of the trunk of said vehicle to the rear by means of a suitable lower flap, to increase the possibilities of loading and transporting objects in said trunk of said vehicle, while preserving easy access to the entire volume of said trunk during loading operations, and, in particular, access to parts of said trunk closest to the rear seats of said vehicle.

On connaît différents types d'ouvrants arrière pour un véhicule automobile, en particulier pour augmenter les possibilités de transport dans le coffre desdits véhicules. Ces ouvrants comportent généralement au moins une partie dont les mouvements permettent, notamment par prolongement du plancher du coffre dudit véhicule vers l'arrière, d'augmenter la surface du plancher dudit coffre, ainsi que, dans certains cas, la hauteur du pas de chargement dans ledit coffre afin de simplifier les opérations de chargement dans ledit coffre.  Various types of rear doors are known for a motor vehicle, in particular to increase the possibilities of transport in the trunk of said vehicles. These opening generally comprise at least one part whose movements allow, in particular by extending the floor of the trunk of said vehicle towards the rear, to increase the floor area of said trunk, and, in some cases, the height of the loading step in said trunk to simplify the loading operations in said trunk.

Le document DE 4103651 présente ainsi un dispositif d'ouvrant arrière d'un véhicule, comportant un abattant inférieur et une partie supérieure escamotable dans ledit abattant inférieur, ledit abattant inférieur étant lié aux parois latérales intérieures du coffre dudit véhicule par un ensemble de bras, l'une des extrémités de chacun desdits bras étant liée par des moyens appropriés audit abattant inférieur, l'autre extrémité de chacun desdits bras étant liée par des moyens appropriés à l'une des parois intérieures dudit coffre, à proximité du plancher dudit coffre. En position fermée de l'ouvrant, ledit abattant inférieur et ladite partie supérieure obturent l'ouverture arrière du coffre dudit véhicule selon un plan sensiblement perpendiculaire au plancher dudit coffre. En position ouverte dudit ouvrant, lorsque ladite partie supérieure (généralement, une vitre) est escamotée dans ledit abattant inférieur, ce dernier peut être déplacé selon deux modes afin de dégager ladite ouverture dudit coffre. Dans l'un desdits modes, lesdits bras précédemment mentionnés pivotent autour des points de liaison situés à chacune de leurs extrémités, de manière à entraîner ledit abattant inférieur vers le haut ou le bas du véhicule, ledit abattant inférieur restant sensiblement perpendiculaire au plancher dudit coffre au cours de son mouvement. Dans le second desdits modes, lesdits bras précédemment mentionnés pivotent autour des points de liaison situés à chacune de leurs extrémités, de manière à entraîner ledit abattant inférieur vers une position dans laquelle il forme sensiblement un prolongement du plancher du coffre dudit véhicule. Le premier mode d'ouverture décrit permet l'accès direct au coffre du véhicule, sans toutefois augmenter la surface du plancher dudit coffre. Dans le second mode décrit, ledit plancher dudit coffre est rallongé de la longueur dudit abattant inférieur: dans ce cas toutefois, l'accès à la totalité du volume dudit coffre peut être diminué, notamment l'accès aux parties dudit coffre les plus proches des banquettes arrière dudit véhicule.  The document DE 4103651 thus has a rear opening device of a vehicle, comprising a lower flap and a retractable upper part in said lower flap, said lower flap being connected to the inner side walls of the trunk of said vehicle by a set of arms, one of the ends of each of said arms being connected by appropriate means to said lower flap, the other end of each of said arms being connected by appropriate means to one of the inner walls of said safe near the floor of said safe. In the closed position of the opening, said lower flap and said upper part close the rear opening of the trunk of said vehicle in a plane substantially perpendicular to the floor of said trunk. In the open position of said opening, when said upper part (usually a window) is retracted into said lower flap, the latter can be moved in two modes to clear said opening of said safe. In one of said modes, said arms mentioned above pivot around the connection points located at each of their ends, so as to cause said lower flap up or down the vehicle, said lower flap remaining substantially perpendicular to the floor of said trunk during his movement. In the second of said modes, said arms mentioned above pivot around the connection points located at each of their ends, so as to cause said lower flap to a position in which it substantially forms an extension of the floor of the trunk of said vehicle. The first described opening mode allows direct access to the trunk of the vehicle, without increasing the floor area of said trunk. In the second described mode, said floor of said trunk is extended by the length of said lower flap: in this case, however, access to the entire volume of said trunk can be decreased, including access to parts of said trunk closest to rear seats of the said vehicle.

Le document US 20030164622 présente, pour sa part, différents modes d'augmentation des possibilités de chargement et de transport dans le coffre d'un véhicule automobile, ainsi que différents modes d'accès audit coffre. Dans ces différents modes, un abattant arrière peut être ouvert par pivotement autour d'un axe sensiblement perpendiculaire au plancher dudit coffre et placé à proximité d'un des montants latéraux arrières dudit coffre afin de dégager l'accès à la totalité du volume dudit coffre. En outre, afin d'étendre les possibilités de transport d'objets, en particulier volumineux, ledit abattant est fixé à l'arrière d'un caisson placé dans ledit coffre et dont la largeur est sensiblement identique à celle de l'intérieur dudit coffre, ledit caisson étant mobile en translation dans une direction sensiblement parallèle à l'axe longitudinal dudit véhicule, de manière à pouvoir constituer une extension dudit coffre fermée sur ses côtés. Là encore, toutefois, dans la position où ledit caisson forme extension dudit coffre, l'accès à la totalité du volume dudit coffre est difficile. voire impossible, notamment en ce qui concerne les parties dudit coffre les plus proches des banquettes arrière dudit véhicule.  The document US 20030164622 presents, for its part, different ways of increasing the possibilities of loading and transport in the trunk of a motor vehicle, as well as different modes of access to said trunk. In these different modes, a rear flap can be pivotally opened about an axis substantially perpendicular to the floor of said trunk and placed near one of the rear lateral uprights of said trunk to clear access to the entire volume of said trunk . In addition, in order to extend the possibilities of transporting objects, particularly bulky, said flap is fixed to the rear of a box placed in said box and whose width is substantially identical to that of the inside of said box , said box being movable in translation in a direction substantially parallel to the longitudinal axis of said vehicle, so as to be an extension of said closed box on its sides. Again, however, in the position where said box forms extension of said chest, access to the entire volume of said chest is difficult. even impossible, particularly with regard to the parts of said trunk closest to the rear seats of said vehicle.

La présente invention a pour but de proposer un dispositif d'ouvrant arrière d'un véhicule automobile permettant l'augmentation de la surface du plancher du coffre dudit véhicule afin d'étendre les possibilités de chargement et de transport dans ledit coffre, tout en préservant un accès facile à la totalité du volume dudit coffre, et, notamment, aux parties dudit coffre les plus proches des banquettes arrières dudit véhicule.  The present invention aims to provide a rear opening device of a motor vehicle for increasing the floor area of the trunk of said vehicle to extend the possibilities of loading and transport in said trunk, while preserving easy access to the entire volume of said trunk, and, in particular, parts of said trunk closest to the rear seats of said vehicle.

L'invention atteint son but grâce à un ouvrant arrière d'un véhicule automobile, comportant une partie supérieure et un abattant inférieur, ladite partie supérieure étant par exemple constituée d'une vitre; ledit ouvrant arrière pouvant, notamment, prendre une position fermée dans laquelle ledit abattant inférieur et ladite partie supérieure obturent sensiblement l'ouverture arrière du coffre dudit véhicule; ledit ouvrant arrière pouvant également prendre une position ouverte dans laquelle ladite partie supérieure peut être manoeuvrée indépendamment dudit abattant inférieur et dans laquelle ledit abattant inférieur, par pivotement autour d'un axe sensiblement parallèle à la direction transversale dudit véhicule et situé au voisinage du plancher dudit coffre dudit véhicule, atteint une position finale dans laquelle il forme sensiblement un prolongement dudit plancher dudit coffre, caractérisé en ce que ledit abattant inférieur est constitué de deux parties liées entre elles par des moyens appropriés.  The invention achieves its goal through a rear leaf of a motor vehicle, comprising an upper portion and a lower flap, said upper portion being for example constituted by a window; said rear opening may, in particular, take a closed position in which said lower flap and said upper part substantially close the rear opening of the trunk of said vehicle; said rear opening can also take an open position in which said upper part can be operated independently of said lower flap and in which said lower flap, by pivoting about an axis substantially parallel to the transverse direction of said vehicle and located in the vicinity of the floor of said trunk of said vehicle, reaches an end position in which it substantially forms an extension of said floor of said trunk, characterized in that said lower flap consists of two parts interconnected by appropriate means.

Dans un mode de réalisation préféré de l'invention, les largeurs respectives de chacune desdites parties dudit abattant inférieur sont sensiblement identiques et égales à la largeur de l'intérieur dudit coffre, et, lorsque ledit ouvrant arrière est en position ouverte dans laquelle ledit abattant inférieur forme sensiblement un prolongement dudit plancher dudit coffre, lesdits moyens appropriés permettent la translation de l'une desdites parties dudit abattant inférieur par rapport à l'autre dans une direction sensiblement parallèle à la direction transversale du véhicule.  In a preferred embodiment of the invention, the respective widths of each of said parts of said lower flap are substantially identical to and equal to the width of the interior of said box, and when said rear door is in the open position in which said flap lower part substantially an extension of said floor of said trunk, said appropriate means allow the translation of one of said parts of said lower flap relative to the other in a direction substantially parallel to the transverse direction of the vehicle.

Avantageusement, une seule desdites parties dudit abattant inférieur est mobile en translation dans une direction sensiblement parallèle à la direction transversale dudit véhicule, l'autre partie dudit abattant inférieur restant alors fixe dans le prolongement dudit plancher dudit coffre dudit véhicule.  Advantageously, only one of said parts of said lower flap is movable in translation in a direction substantially parallel to the transverse direction of said vehicle, the other part of said lower flap then remaining fixed in the extension of said floor of said trunk of said vehicle.

Avantageusement, l'invention peut présenter l'une ou l'autre des caractéristiques suivantes - lesdits moyens appropriés comportent, lorsque ledit abattant inférieur est en position ouverte dans laquelle il forme sensiblement un prolongement du plancher du coffre du véhicule, un élément sensiblement dirigé selon un axe sensiblement parallèle à l'axe longitudinal du véhicule, placé à l'une des extrémités latérales dudit abattant inférieur proche d'un montant latéral arrière du coffre dudit véhicule, ladite partie mobile en translation selon une direction sensiblement parallèle à la direction transversale du véhicule est également mobile en rotation autour dudit élément dirigé selon un axe sensiblement parallèle audit axe longitudinal dudit véhicule, de manière à prendre une position sensiblement perpendiculaire au plancher du coffre dudit véhicule, lesdits moyens appropriés permettent le retrait et la mise en place manuelle de 30 ladite partie mobile en translation et en rotation dudit abattant inférieur sur l'autre dite partie dudit abattant inférieur.  Advantageously, the invention may have one or the other of the following characteristics - said appropriate means comprise, when said lower flap is in the open position in which it substantially forms an extension of the floor of the trunk of the vehicle, an element substantially directed according to an axis substantially parallel to the longitudinal axis of the vehicle, placed at one of the lateral ends of said lower flap near a rear lateral upright of the trunk of said vehicle, said part movable in translation in a direction substantially parallel to the transverse direction of the vehicle; vehicle is also rotatable about said element directed along an axis substantially parallel to said longitudinal axis of said vehicle, so as to take a position substantially perpendicular to the floor of the trunk of said vehicle, said appropriate means allow the removal and manual placement of 30 said moving part in t ranslation and rotation of said lower flap on the other said part of said lower flap.

D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture de la description qui suit, en référence aux dessins annexés dans lesquels: - la figure 1 est un dessin simplifié en perspective d'un véhicule automobile vu de trois quart arrière, dans lequel l'ouvrant arrière est en position fermée, la figure 2 est un dessin simplifié en perspective d'un véhicule automobile vu de trois quart arrière, équipé d'un ouvrant arrière selon l'invention, dans lequel ledit ouvrant arrière est en. position ouverte, la figure 3 est un dessin simplifié en perspective d'un véhicule vu. de trois quart 5 arrière, équipé d'un ouvrant arrière selon l'invention, présentant l'une des possibilités de mouvement desdites parties de l'abattant inférieur, la figure 4 est un dessin en perspective simplifié d'un véhicule vu de trois quart arrière, équipé d'un ouvrant arrière selon l'invention, présentant une autre des possibilités de mouvement desdites parties dudit abattant inférieur.  Other features and advantages of the invention will appear on reading the description which follows, with reference to the appended drawings, in which: FIG. 1 is a simplified perspective drawing of a motor vehicle seen from three quarter rear, in which the rear opening is in the closed position, Figure 2 is a simplified perspective drawing of a motor vehicle seen three quarter rear, equipped with a rear door according to the invention, wherein said rear door is in. open position, Figure 3 is a simplified drawing in perspective of a vehicle seen. three quarter rear, equipped with a rear door according to the invention, having one of the possibilities of movement of said parts of the lower flap, Figure 4 is a simplified perspective drawing of a vehicle seen from three quarters rear, equipped with a rear door according to the invention, having another of the possibilities of movement of said parts of said lower flap.

La figure 1 présente un véhicule automobile 1 équipé d'un ouvrant arrière composé d'une partie supérieure 2 et d'un abattant inférieur 3.  FIG. 1 shows a motor vehicle 1 equipped with a rear opening composed of an upper part 2 and a lower flap 3.

Selon un mode de réalisation bien connu dans l'état de la technique, ladite partie supérieure 2 est avantageusement constituée d'une vitre et peut être ouverte indépendamment dudit abattant inférieur 3, par exemple par pivotement, vers le haut dudit véhicule 1, autour d'un axe 4,71 sensiblement parallèle à la direction transversale X dudit véhicule 1 et sensiblement placé à l'intersection de ladite partie supérieure 2 dudit ouvrant et du toit 4 dudit véhicule 1.  According to an embodiment well known in the state of the art, said upper portion 2 is advantageously constituted by a window and can be opened independently of said lower flap 3, for example by pivoting upwards of said vehicle 1, around the window. an axis 4,71 substantially parallel to the transverse direction X of said vehicle 1 and substantially placed at the intersection of said upper part 2 of said opening and roof 4 of said vehicle 1.

L'abattant inférieur 3 peut, quant à lui, dans un mode de réalisation également bien connu dans l'état de la technique et présenté sur la figure 2, être rabattu vers l'extérieur du véhicule 1 par pivotement autour d'un axe sensiblement parallèle à ladite direction transversale X dudit véhicule 1 et sensiblement placé au voisinage de l'intersection entre ledit abattant inférieur 3 et le plancher 5 du coffre 6 du véhicule 1, de manière à atteindre une position ouverte dans laquelle ledit abattant inférieur 3 prolonge sensiblement ledit plancher 5 afin d'augmenter les possibilités de chargement et de transport dans ledit coffre 6.  The lower flap 3 may, for its part, in an embodiment also well known in the prior art and shown in Figure 2, be folded towards the outside of the vehicle 1 by pivoting about an axis substantially parallel to said transverse direction X of said vehicle 1 and substantially placed in the vicinity of the intersection between said lower flap 3 and the floor 5 of the trunk 6 of the vehicle 1, so as to reach an open position in which said lower flap 3 substantially extends said floor 5 to increase the possibilities of loading and transport in said trunk 6.

Comme le montre la figure 2, ledit abattant inférieur 3 selon l'invention est constitué de deux parties 3a et 3b dont les largeurs respectives sont sensiblement identiques et égales à la largeur de l'intérieur dudit coffre 6, lesdites parties 3a et 3b comportant entre elles des moyens de liaison appropriés non représentés sur les figures, ladite partie 3a étant la partie dudit abattant inférieur 3 la plus proche dudit plancher 5 dudit coffre 6.  As shown in FIG. 2, said lower flap 3 according to the invention consists of two parts 3a and 3b whose respective widths are substantially identical and equal to the width of the inside of said box 6, said parts 3a and 3b having between they are appropriate connecting means not shown in the figures, said part 3a being the part of said bottom flap 3 closest to said floor 5 of said box 6.

Dans un mode de réalisation préféré de l'invention et comme le montre la figure 3, lesdits 35 moyens de liaison entre lesdites parties 3a et 3b permettent, lorsque l'abattant inférieur 3 est en position ouverte dans laquelle il forme sensiblement un prolongement du plancher 5 du coffre 6 du véhicule 1, la translation de ladite partie 3b par rapport à ladite partie 3a, selon une direction sensiblement parallèle à la direction transversale X du véhicule 1. Ledit mouvement de translation est matérialisé par la double flèche F sur la figure 3. Par exemple et de manière non limitative, lesdits moyens de liaison peuvent consister en un ensemble d'éléments fixés par des moyens appropriés sur ladite partie 3b et coulissant dans un ensemble de rails ou guides fixés par des moyens appropriés sur ladite partie 3a. Tout autre moyen permettant une translation aisée de ladite partie 3b par rapport à ladite partie 3a peut également être retenu sans inconvénient pour l'invention.  In a preferred embodiment of the invention and as shown in FIG. 3, said connection means between said parts 3a and 3b make it possible, when the lower flap 3 is in the open position in which it substantially forms an extension of the floor. 5 of the trunk 6 of the vehicle 1, the translation of said portion 3b relative to said portion 3a, in a direction substantially parallel to the transverse direction X of the vehicle 1. Said translational movement is embodied by the double arrow F in Figure 3 For example and without limitation, said connecting means may consist of a set of elements fixed by appropriate means on said portion 3b and sliding in a set of rails or guides fixed by appropriate means on said portion 3a. Any other means allowing easy translation of said portion 3b with respect to said portion 3a can also be retained without disadvantage for the invention.

Avantageusement, ladite partie 3a reste fixe dans le prolongement dudit plancher 5 pendant ladite translation de ladite partie 3b, et la longueur 1 du prolongement dudit plancher 5 par ladite partie 3a est suffisamment importante pour permettre que la translation de ladite partie 3b ne soit pas limitée par la présence des montants arrières latéraux 7 dudit coffre 6, tout en restant suffisamment faible pour ne pas engendrer de gêne dans l'accès à la totalité du volume dudit coffre 6, et notamment aux parties dudit coffre 61.es plus proches des banquettes arrières dudit véhicule 1.  Advantageously, said portion 3a remains fixed in the extension of said floor 5 during said translation of said portion 3b, and the length 1 of the extension of said floor 5 by said portion 3a is large enough to allow the translation of said portion 3b is not limited by the presence of the rear lateral uprights 7 of said trunk 6, while remaining small enough not to cause discomfort in access to the entire volume of said trunk 6, and in particular to the parts of said trunk 61. are closer to the rear seats said vehicle 1.

Il est ainsi possible à un utilisateur ayant, au préalable, déplacé ladite partie 3b par rapport à ladite partie 3a selon le mouvement de translation précédemment décrit, de charger un objet dans ledit coffre 6 dudit véhicule L Lorsque ledit utilisateur ramène ensuite ladite partie 3b dans sa position initiale dans laquelle ladite partie 3b prolonge sensiblement ladite partie 3a et ledit plancher 5 dudit coffre 6, il bénéficie alors de l'augmentation de la surface dudit plancher 5 dudit coffre 6 résultant du prolongement dudit plancher 5 par ledit abattant inférieur 3 dans sa totalité (parties 3a et 3b).  It is thus possible for a user who has previously moved said part 3b with respect to said part 3a according to the previously described translation movement, to load an object into said box 6 of said vehicle L When said user then brings said part 3b into its initial position in which said portion 3b substantially extends said portion 3a and said floor 5 of said box 6, it then benefits from the increase in the area of said floor 5 of said box 6 resulting from the extension of said floor 5 by said lower flap 3 in its all (parts 3a and 3b).

Selon une variante de réalisation non représentée, l'abattant peut avoir une forme courbe, la partie 3b pouvant alors coulisser sur un rail permettant de suivre le profil de l'abattant, et d'obtenir ainsi une position sensiblement verticale, en fonction de la courbure, en limitant ainsi le dépassement de la partie 3b. De manière générale la translation de la partie 3b par rapport à la partie 3a est réalisée selon une direction sensiblement parallèle à la forme du bord de la partie 3a.  According to an alternative embodiment not shown, the flap can have a curved shape, the portion 3b can then slide on a rail to follow the profile of the flap, and thus obtain a substantially vertical position, depending on the curvature, thus limiting the exceeding of part 3b. In general, the translation of the portion 3b with respect to the portion 3a is made in a direction substantially parallel to the shape of the edge of the portion 3a.

Dans un autre mode de réalisation de l'invention, et ainsi que le montre la figure 4, lesdits moyens de liaison entre lesdites parties 3a et 3b comportent notamment un élément 8 (non représenté sur la figure) dirigé, lorsque ledit abattant inférieur 3 est en position ouverte dans laquelle il forme sensiblement un prolongement dudit plancher 5 dudit coffre 6, selon un axe C sensiblement parallèle à l'axe longitudinal Y dudit véhicule 1, ledit élément 8 étant placé sur l'un des bords desdites parties 3a et 3b proche d'un desdits montants latéraux arrière 7 dudit coffre 6, ladite partie 3b étant mobile en rotation autour dudit élément 8.  In another embodiment of the invention, and as shown in FIG. 4, said connection means between said parts 3a and 3b comprise in particular an element 8 (not shown in the figure) directed, when said lower flap 3 is in the open position in which it substantially forms an extension of said floor 5 of said box 6, along an axis C substantially parallel to the longitudinal axis Y of said vehicle 1, said element 8 being placed on one of the edges of said parts 3a and 3b close one of said rear side uprights 7 of said box 6, said part 3b being rotatable about said element 8.

Pour les opérations de chargement du coffre 6, l'utilisateur peut alors faire pivoter ladite partie 3b autour dudit axe C matérialisé par ledit élément 8, de manière à amener ladite partie 3b dans une position sensiblement perpendiculaire au plancher 5 dudit coffre 6, ainsi que le montre la flèche H représentée sur la figure 4. L'accès à la totalité dudit coffre 6 est ainsi dégagé, l'utilisateur pouvant ensuite, en ramenant ladite partie 3b dudit abattant inférieur 3 dans sa position initiale dans laquelle ledit abattant inférieur 3 constitué desdites parties 3a et 3b forme sensiblement un prolongement dudit plancher 5 dudit coffre 6, augmenter ainsi la surface dudit plancher 5 pour le chargement et le transport d'objets volumineux, par exemple, Il est à noter que, dans ce cas, de même que lors du mouvement de translation de ladite partie 3b précédemment décrit, ladite partie 3a reste fixe dans le prolongement dudit plancher 5 dudit coffre 6.  For the loading operations of the trunk 6, the user can then rotate said portion 3b about said axis C embodied by said element 8, so as to bring said portion 3b in a position substantially perpendicular to the floor 5 of said trunk 6, as well as shows the arrow H shown in Figure 4. Access to the entire chest 6 is thus released, the user can then, by bringing said portion 3b of said lower flap 3 in its initial position in which said lower flap 3 constituted said portions 3a and 3b substantially form an extension of said floor 5 of said box 6, thereby increasing the area of said floor 5 for loading and transporting bulky objects, for example. It should be noted that in this case, as well as during the translational movement of said portion 3b previously described, said portion 3a remains fixed in the extension of said floor 5 of said box 6.

Avantageusement, lesdits moyens de liaison entre ladite partie 3a et ladite partie 3b dudit abattant inférieur 3 peuvent également permettre la mise en place et le retrait manuel de ladite partie 3b, augmentant ainsi la modularité et la souplesse de l'agencement dudit ouvrant arrière selon l'invention.  Advantageously, said connection means between said portion 3a and said portion 3b of said lower flap 3 can also allow the establishment and manual removal of said portion 3b, thereby increasing the modularity and flexibility of the arrangement of said rear door according to the invention. 'invention.

Il est à noter que les différents modes de réalisation présentés peuvent, sans inconvénient pour l'invention, être combinés entre eux.  It should be noted that the various embodiments presented may, without disadvantage for the invention, be combined with each other.
