Description

Véhicule automobile doté d'un hayon mobile  Motor vehicle with a liftgate
La présente invention concerne de manière générale les véhicules automobiles, et plus particulièrement les véhicules équipés d'un hayon mobile. The present invention relates generally to motor vehicles, and more particularly to vehicles equipped with a mobile tailgate.
Conventionnellement, de nombreux véhicules comprennent des portes latérales et un hayon monté à pivotement à l ' arrière de la carrosserie du véhicule.  Conventionally, many vehicles include side doors and a tailgate pivotally mounted to the rear of the vehicle body.
Les hayons arrière sont principalement conçus à la fois pour assurer l 'optimisation de l ' ouverture d' accès à l ' espace de chargement arrière et pour fournir un plus grand espace de chargement.  The tailgates are primarily designed to both optimize the access opening to the rear cargo space and provide greater cargo space.
L 'ouverture du hayon se fait habituellement par un mouvement glissant du hayon.  The opening of the tailgate is usually done by a sliding movement of the tailgate.
Dans certains cas, un hayon supérieur comprenant une fenêtre arrière ou un hayon inférieur est apte à coulisser, ou bien les deux, indépendamment ou non.  In some cases, an upper tailgate comprising a rear window or a lower hatch is slidable, or both, independently or not.
Par exemple, la demande de brevet US 2012 032473 décrit un hayon supérieur, comprenant une fenêtre arrière, apte à coulisser pour l ' opération d' ouverture. L 'ouverture coulissante ne peut se produire qu' après l'ouverture d'un ensemble de toit panoramique . Puis le hayon coulisse jusqu' à une position entièrement ouverte sous le toit ouvert. Toutefois, le hayon inférieur est indépendant et ne peut qu' être ouvert et fermé de façon pivotante.  For example, US patent application 2012 032473 discloses an upper tailgate, comprising a rear window, slidable for the opening operation. The sliding opening can only occur after opening a panoramic roof assembly. Then the tailgate slides to a fully open position under the open roof. However, the lower tailgate is independent and can only be opened and closed pivotally.
Ce mécanisme est adapté aux véhicules équipés d'un ensemble de toit panoramique, ce qui n' est pas le cas pour la majorité des véhicules.  This mechanism is suitable for vehicles equipped with a panoramic roof assembly, which is not the case for the majority of vehicles.
Un autre inconvénient concerne la complexité du mécanisme d' ouverture, due principalement au nombre d' éléments impliqués mais aussi au nombre d' étapes que le conducteur doit exécuter avant de pouvoir ouvrir la porte arrière. De plus, le hayon supérieur peut coulisser au-dessus de la partie arrière du véhicule, mais pas la porte arrière entière. Dans le document EP 1706284 , un autre mécanisme d' ouverture est décrit. Dans ce système, le hayon est décrit comme étant apte à se déplacer vers le toit et à reposer sur celui-ci à l' aide d'un ou de plusieurs leviers. Chaque levier peut tourner autour d'un axe de rotation qui est situé sur son extrémité qui n' est pas connectée au hayon. Another disadvantage relates to the complexity of the opening mechanism, due mainly to the number of elements involved but also to the number of steps that the driver must perform before opening the rear door. In addition, the top tailgate can slide over the rear of the vehicle, but not the entire rear door. In EP 1706284, another opening mechanism is described. In this system, the tailgate is described as being able to move to the roof and rest on it with one or more levers. Each lever can rotate about an axis of rotation which is located on its end which is not connected to the tailgate.
Les principaux inconvénients concernent le poids et la complexité du mécanisme. Les opérations d' ouverture et de fermeture du hayon sont difficiles et le guidage du hayon sur le toit n' est pas suffisamment précis .  The main disadvantages concern the weight and the complexity of the mechanism. The opening and closing operations of the tailgate are difficult and the guidance of the tailgate on the roof is not precise enough.
En conséquence, la présente invention a pour but d' apporter une réponse à ces inconvénients en proposant un mécanisme simple et facile à actionner, apte à faire monter la porte arrière entière vers le toit.  Accordingly, the present invention aims to provide an answer to these disadvantages by providing a simple and easy to operate mechanism, able to raise the entire rear door to the roof.
Un obj et de la présente invention est de fournir un véhicule automobile qui comprend une carrosserie et un hayon mobile dirigé par un élément stabilisateur.  An object of the present invention is to provide a motor vehicle which comprises a body and a tailgate driven by a stabilizing element.
Par ailleurs, un rail de guidage est monté sur un côté de la partie supérieure de la carrosserie, ledit rail s ' étendant sur la partie arrière de la carrosserie. Au moins un support est attaché de manière fixe au hayon, ledit support étant adapté pour coulisser le long dudit rail. L ' élément stabilisateur est monté à pivotement sur ladite carrosserie et est connecté directement au hayon.  Furthermore, a guide rail is mounted on one side of the upper part of the bodywork, said rail extending on the rear part of the bodywork. At least one support is fixedly attached to the tailgate, said support being adapted to slide along said rail. The stabilizing element is pivotally mounted on said body and is directly connected to the tailgate.
De façon avantageuse, un deuxième rail est monté de l ' autre côté de la partie supérieure de la carrosserie.  Advantageously, a second rail is mounted on the other side of the upper part of the bodywork.
De façon plus avantageuse, un deuxième élément stabilisateur est monté à pivotement sur la carrosserie et est connecté directement au hayon.  More advantageously, a second stabilizing element is pivotally mounted on the body and is directly connected to the tailgate.
De préférence, le support est adapté pour glisser le long du rail au moyen d'un tenon mobile qui est avantageusement connecté au support au moyen d'une roulette .  Preferably, the support is adapted to slide along the rail by means of a movable pin which is advantageously connected to the support by means of a roller.
En outre, une gâche et un loquet, montés sur le hayon, peuvent être reliés à un câble d' ouverture de hayon qui permet au conducteur du véhicule de commander l ' ouverture du hayon depuis l' intérieur du véhicule. In addition, a strike and a latch, mounted on the tailgate, can be connected to a hatch opening cable that allows the driver of the vehicle to control the opening of the tailgate from inside the vehicle.
Selon un autre aspect de l' invention, l'ouverture du hayon est motorisée.  According to another aspect of the invention, the opening of the tailgate is motorized.
Avantageusement, le hayon comprend une partie inférieure et une partie supérieure, l ' élément stabilisateur étant connecté à ladite partie inférieure.  Advantageously, the tailgate comprises a lower part and an upper part, the stabilizing element being connected to said lower part.
Dans un mode de réalisation, l ' axe de pivotement de l ' élément stabilisateur est situé près de l ' axe de la roulette ou même au même endroit que l ' axe de la roulette quand le hayon est en position fermée. Ceci assure un transfert de forces efficace de l ' élément stabilisateur au hayon, en particulier pendant l' ouverture du hayon.  In one embodiment, the pivot axis of the stabilizer element is located near the axis of the wheel or even at the same location as the wheel axis when the tailgate is in the closed position. This ensures effective transfer of forces from the stabilizing element to the tailgate, particularly during opening of the tailgate.
Les dimensions du support sont de préférence telles que dans la position entièrement ouverte, la partie supérieure du hayon se trouve au-dessus de la carrosserie.  The dimensions of the support are preferably such that in the fully open position, the upper part of the tailgate is above the bodywork.
D ' autres avantages et caractéristiques de l' invention apparaîtront à l ' examen de la description détaillée d'un mode de réalisation de l' invention, qui est un exemple non limitatif, illustré sur les dessins annexés dans lesquels :  Other advantages and characteristics of the invention will appear on examining the detailed description of an embodiment of the invention, which is a non-limiting example, illustrated in the accompanying drawings in which:
- la figure 1 est une vue latérale d'un hayon sur un véhicule selon l' invention, le hayon étant en position fermée ;  - Figure 1 is a side view of a tailgate on a vehicle according to the invention, the tailgate is in the closed position;
- la figure 2 est une vue latérale du même véhicule pendant l ' ouverture du hayon ; et  - Figure 2 is a side view of the same vehicle during the opening of the tailgate; and
- la figure 3 est une vue latérale du même véhicule avec le hayon dans une position entièrement ouverte.  - Figure 3 is a side view of the same vehicle with the tailgate in a fully open position.
Comme montré sur la figure 1 , un véhicule comprend une carrosserie 1 , comprenant un hayon 2. La carrosserie 1 a une partie arrière 102 sur laquelle est positionné le hayon 2 et une partie supérieure 101 . Le hayon 2 comprend aussi une partie supérieure 201 , avec une fenêtre arrière et une partie inférieure 202.  As shown in Figure 1, a vehicle comprises a body 1, comprising a tailgate 2. The body 1 has a rear portion 102 on which is positioned the tailgate 2 and an upper portion 101. The tailgate 2 also comprises an upper part 201, with a rear window and a lower part 202.
A l ' arrière du véhicule, deux rails de guidage 3 s ' étendent de chaque côté de la carrosserie 1 , de la partie supérieure 101 à la partie arrière 102. Chaque rail 3 comprend une partie horizontale 301 , une partie courbée 302 et une partie verticale 303. Dans un mo de de réalisation préféré, on place des rails de guidage identiques, chacun sur un côté de la carrosserie du véhicule . Les deux rails de guidage ont la même structure. Seul le rail de guidage 3 situé du côté gauche de la carrosserie du véhicule est visible sur les figures, étant entendu qu'un rail de guidage identique est placé sur le côté droit de la carrosserie du véhicule. At the rear of the vehicle, two guide rails 3 extend on each side of the body 1, from the upper part 101 to the rear part 102. Each rail 3 comprises a horizontal part 301, a curved part 302 and a part vertical 303. In a mo de of In a preferred embodiment, identical guide rails are placed each on one side of the vehicle body. The two guide rails have the same structure. Only the guide rail 3 located on the left side of the vehicle body is visible in the figures, it being understood that an identical guide rail is placed on the right side of the vehicle body.
Dans d' autres modes de réalisation de l 'invention, la carrosserie du véhicule pourrait être pourvue d'un seul rail de guidage placé sur un côté de la carrosserie du véhicule.  In other embodiments of the invention, the vehicle body could be provided with a single guide rail on one side of the vehicle body.
Comme illustré, le hayon 2 est lié au rail 3 par deux éléments, un support 4 et un élément stabilisateur 5 . Le support 4 peut être fixé d'un côté au hayon 2, de préférence sur la partie supérieure 201 , par exemple par soudage ou par tout moyen équivalent approprié . Sur son extrémité libre, le support 4 comporte un tenon 7 et une roulette 8 qui coopère avec le rail de guidage 3. Quand deux rails de guidage identiques sont placés sur la carrosserie du véhicule 1 , le hayon 2 comporte un support similaire avec un tenon et une roulette similaires sur ses deux côtés, destinés à coopérer avec les deux rails de guidage.  As illustrated, the tailgate 2 is connected to the rail 3 by two elements, a support 4 and a stabilizing element 5. The support 4 can be fixed on one side to the tailgate 2, preferably on the upper part 201, for example by welding or by any equivalent appropriate means. On its free end, the support 4 comprises a pin 7 and a wheel 8 which cooperates with the guide rail 3. When two identical guide rails are placed on the body of the vehicle 1, the tailgate 2 comprises a similar support with a tenon and a similar wheel on both sides, intended to cooperate with the two guide rails.
En ce qui concerne l ' élément stabilisateur 5 , un petit support 6 permet le montage de sa première extrémité sur la partie inférieure 202 du hayon 2, tandis que sa deuxième extrémité est fixée sur la partie verticale 303 du rail 3 , aussi près que possible de l ' extrémité inférieure de ladite partie 303 , presque à la même position que le tenon 7 et la roulette 8 quand le hayon est dans la position fermée, comme illustré sur la figure 1 . Dans certains modes de réalisation, un seul stabilisateur 5 peut être placé sur un côté de la carrosserie du véhicule 1 . Dans d' autres modes de réalisation, un élément stabilisateur peut être placé des deux côtés de la carrosserie du véhicule 1 , ce qui donne une structure plus so lide et permet une meilleure assistance pour l ' opération d' ouverture du hayon 2.  Regarding the stabilizing element 5, a small support 6 allows the mounting of its first end on the lower part 202 of the tailgate 2, while its second end is fixed on the vertical portion 303 of the rail 3, as close as possible of the lower end of said portion 303, almost at the same position as the pin 7 and the wheel 8 when the tailgate is in the closed position, as illustrated in FIG. 1. In some embodiments, a single stabilizer 5 may be placed on one side of the vehicle body 1. In other embodiments, a stabilizing element can be placed on both sides of the vehicle body 1, which provides a more secure structure and provides better assistance for the opening operation of the tailgate 2.
Comme montré sur la figure 3 , le verrouillage et le déverrouillage du hayon 2 sont rendus possibles à la fois par un loquet 9 fixé sur la partie inférieure du hayon 202 et par une gâche 1 0 fixée sur la partie arrière 1 02 de la carrosserie. Un câble d' ouverture de hayon 1 1 est relié à la gâche 10 afin de permettre au conducteur d' ouvrir le hayon depuis l ' intérieur du véhicule, par l' intermédiaire d'un levier 12. As shown in Figure 3, the locking and unlocking of the tailgate 2 are made possible by both a latch 9 fixed on the lower part of the tailgate 202 and a keeper 1 0 fixed on the rear part 1 02 of the body. An opening cable The hatch 1 1 is connected to the striker 10 to allow the driver to open the tailgate from inside the vehicle by means of a lever 12.
Comme montré sur la figure 1 , dans une première étape, le hayon 2 est en position fermée. Dans cette configuration, le tenon mobile 7 est situé à l ' extrémité de la partie verticale du rail 303 et donc juste à côté de la deuxième extrémité de l ' élément stabilisateur 5 qui est dans un état étendu.  As shown in Figure 1, in a first step, the tailgate 2 is in the closed position. In this configuration, the movable post 7 is located at the end of the vertical part of the rail 303 and therefore just next to the second end of the stabilizing element 5 which is in an extended state.
Dans cette position fermée, le hayon 2 se trouve sur la partie arrière 1 02.  In this closed position, the tailgate 2 is on the rear part 1 02.
L ' élément stabilisateur 5 peut être par exemple un vérin à gaz, ou tout autre élément, connecté à la fois au hayon 2 et à la partie arrière de la carrosserie 102, et permettant au hayon 2 d' être commandé et stabilisé. L ' élément stabilisateur 5 est prévu pour revenir à son état rétracté. Par conséquent, dès que la gâche 10 a été libérée par une action sur le câble 1 1 , le hayon commence automatiquement son mouvement d' ouverture. Les positions respectives des deux points de fixation de l ' élément stabilisateur 5 , sur la partie inférieure 202 et sur l ' extrémité la plus basse de la partie verticale 303 du rail de guidage 3 permettent de maximiser la force du stabilisateur sur le hayon au début du mouvement d' ouverture.  The stabilizing element 5 may be for example a gas cylinder, or any other element, connected to both the tailgate 2 and the rear part of the body 102, and allowing the tailgate 2 to be controlled and stabilized. The stabilizing element 5 is provided to return to its retracted state. Therefore, as soon as the keeper 10 has been released by an action on the cable 1 1, the tailgate automatically begins its opening movement. The respective positions of the two fixing points of the stabilizing element 5, on the lower part 202 and on the lower end of the vertical part 303 of the guide rail 3 make it possible to maximize the force of the stabilizer on the tailgate at the beginning. opening movement.
Comme montré sur la figure 2, dans une deuxième étape, le hayon 2 s ' ouvre. Le support 4, connecté au tenon mobile 7, est apte à coulisser le long du rail 3 jusqu' à la partie courbée 302, principalement grâce à l ' élément stabilisateur 5 qui passe progressivement à un état rétracté.  As shown in Figure 2, in a second step, the tailgate 2 opens. The support 4, connected to the movable pin 7, is slidable along the rail 3 to the curved portion 302, mainly by means of the stabilizing element 5 which gradually passes to a retracted state.
Dans la position intermédiaire illustrée sur la figure 2, la partie inférieure 202 du hayon est toujours devant la partie arrière 102 de la carrosserie 1 . Toutefois, une portion de la partie supérieure 201 du hayon est déjà devant la partie supérieure 101 de la carrosserie 1 .  In the intermediate position illustrated in FIG. 2, the lower part 202 of the tailgate is always in front of the rear part 102 of the bodywork 1. However, a portion of the upper portion 201 of the tailgate is already in front of the upper portion 101 of the body 1.
Comme montré sur la figure 3 , dans une dernière étape, le hayon 2 a été poussé jusqu' à une position entièrement ouverte. Le support 4 est monté en glissant jusqu' à la partie horizontale 30 1 du rail 3 et a été guidé le long de cette partie 301 . En conséquence, le hayon 2 se trouve au-dessus de la partie supérieure 101 de la carrosserie 1 . As shown in Figure 3, in a final step, the tailgate 2 was pushed to a fully open position. The support 4 is slidably mounted to the horizontal portion 30 1 of the rail 3 and has been guided along this portion 301. As a result, tailgate 2 is above the upper part 101 of the bodywork 1.
L ' élément stabilisateur 5 , que l'on a fait pivoter et qui a été levé avec le mouvement du hayon, reste approximativement dans une position verticale. L ' élément stabilisateur 5 retient le hayon 2, qui ne peut de ce fait aller plus loin que la partie horizontale 301 du rail 3.  The stabilizing element 5, which has been pivoted and lifted with the movement of the tailgate, remains approximately in a vertical position. The stabilizing element 5 retains the tailgate 2, which can not go further than the horizontal portion 301 of the rail 3.
Dans cette position entièrement ouverte, la partie supérieure 201 et la partie inférieure 202 du hayon 2 sont situées au- dessus de la partie supérieure 101 de la carrosserie 1 .  In this fully open position, the upper part 201 and the lower part 202 of the tailgate 2 are situated above the upper part 101 of the bodywork 1.
Le hayon 2 est stabilisé et repose sur le toit en dépit du poids de sa partie inférieure 202.  The tailgate 2 is stabilized and rests on the roof despite the weight of its lower portion 202.
Pour revenir à la position fermée, comme montré sur la figure 1 , le conducteur doit simp lement tirer le hayon 2 vers le bas . Ainsi, le hayon 2 se ferme automatiquement en raison de son propre poids. Les supports 4 de chaque côté de la partie supérieure 101 et de la partie arrière 102 de la carrosserie 1 coulissent le long des rails 3 jusqu' à une position fermée.  To return to the closed position, as shown in Figure 1, the driver should simply pull the tailgate 2 down. Thus, the tailgate 2 closes automatically due to its own weight. The supports 4 on each side of the upper portion 101 and the rear portion 102 of the body 1 slide along the rails 3 to a closed position.
Une roue de secours peut être fixée sur la partie inférieure 202, de telle manière qu' elle peut se déplacer avec le hayon 2 et libère l ' espace qu' elle prendrait dans la zone de chargement arrière. Dans un tel mode de réalisation, en raison du poids de la roue de secours, il peut être préférable de prévoir un système d 'ouverture motorisé.  A spare wheel may be attached to the lower part 202, so that it can move with the tailgate 2 and release the space it would take in the rear loading area. In such an embodiment, because of the weight of the spare wheel, it may be preferable to provide a motorized opening system.
Le hayon mobile de la présente invention, en étant apte à glisser le long des rails de guidage jusqu' au toit du véhicule, facilite considérablement l ' accès à la zone de chargement. L ' ouverture et la fermeture du hayon sont des opérations rapides et faciles .  The mobile tailgate of the present invention, being able to slide along the guide rails to the roof of the vehicle, greatly facilitates access to the loading area. Opening and closing the tailgate is quick and easy.
Quand le véhicule est en stationnement, le conducteur a besoin de moins d' espace à l ' arrière, pendant l ' ouverture et la fermeture, qu' avec un hayon conventionnel. La porte arrière peut facilement être ouverte dans une zone de stationnement restreinte et elle ne nécessite pas d' espace supplémentaire au niveau de la partie arrière du véhicule.  When the vehicle is parked, the driver needs less space at the rear, during opening and closing, than with a conventional tailgate. The rear door can easily be opened in a restricted parking area and does not require additional space at the rear of the vehicle.
En outre, le véhicule peut être conduit avec le hayon en position ouverte pour transporter un bagage vo lumineux ou d' autres grands obj ets à l ' arrière du véhicule. Le hayon mobile de l' invention permet au conducteur d'optimiser le chargement de l'espace utile présent à l'arrière du véhicule. In addition, the vehicle can be driven with the liftgate in the open position to transport a bright luggage or other large objects to the rear of the vehicle. The mobile tailgate of the invention allows the driver to optimize the loading of the usable space at the rear of the vehicle.
De plus, le mécanisme ne comprend que quelques éléments et est simple à fabriquer.  In addition, the mechanism includes only a few elements and is simple to manufacture.
Le hayon de l'invention peut être utilisé pour tout type de véhicule. Il peut aussi être utilisé pour des véhicules du type ambulance, ou même pour des véhicules formant magasins ambulants.  The tailgate of the invention can be used for any type of vehicle. It can also be used for vehicles of the ambulance type, or even for vehicles forming street shops.
