Description

La présente invention concerne de manière générale les hayons pour fermeture et l'ouverture des coffres de véhicules automobiles, et plus particulièrement un hayon dont l'ouverture est réalisée par un mouvement de pivotement vers le du véhicule. The present invention generally relates to tailgate for closing and opening of the trunks of motor vehicles, and more particularly a tailgate whose opening is achieved by a pivoting movement towards the vehicle.

Elle concerne également un véhicule automobile comportant un tel hayon. Actuellement, certains hayons sont équipés de systèmes de retenue assistent leur ouverture et leur fermeture. It also relates to a motor vehicle comprising such a tailgate. Currently, some tailgates are equipped with restraint systems assist their opening and closing.

On connaît<B>déjà</B> comme système de retenue des câbles de retenue positionnés sur les côtés du hayon et liés au hayon ainsi qu'à une partie fixe du véhicule. Toutefois, les câbles de retenue ne permettent pas de limiter la vitesse mouvement du hayon.<B>Il y</B> a donc pour l'utilisateur un risque de choc du hayon lors son ouverture et de pincement des doigts lors de la fermeture dudit hayon. En outre, l'utilisateur risque avec un tel système de retenue de se pincer un doigt ou une main dans le cable de retenue. Pour maintenir le hayon en position fermée, il est nécessaire avec un tel système de retenue d'équiper le hayon d'une serrure supplémentaire. Enfin, il<B>y</B> a également un risque que le câble de retenue se positionne façon incorrecte<B>à</B> la fermeture du hayon, de sorte qu'il se trouve coincer entre hayon et la partie fixe du véhicule en provoquant un endommagement du joint d'étanchéité positionné autour dudit hayon. Already known <B> already </ B> as restraining system retaining cables positioned on the sides of the tailgate and linked to the tailgate and a fixed part of the vehicle. However, the restraining cables can not limit the movement speed of the tailgate. <B> There is </ B> therefore for the user a risk of shock of the tailgate when opening and pinching fingers when closing said tailgate. In addition, the user risk with such a restraint system to pinch a finger or a hand in the retaining cable. To maintain the tailgate in the closed position, it is necessary with such a restraint system to equip the tailgate with an additional lock. Finally, it <B> y </ B> also has a risk that the restraint cable will position itself incorrectly <B> at </ B> closing the tailgate, so that it gets squeezed between tailgate and the part fixed position of the vehicle causing damage to the seal positioned around said tailgate.

On connaît également comme système de retenue, des équilibreurs <B>à</B> gaz positionnés chaque côté du hayon- Ces équilibreurs<B>à</B> gaz sont des systèmes complexes qui nécessitent un agencement spécial de la caisse du véhicule automobile pour les accueillir, lorsque le hayon est position fermée. De plus, il est également nécessaire d'équiper le hayon d'une serrure de verrouillage pour maintenir verrouillé le hayon en position fermée sur le véhicule. Also known as a restraint system are gas balancers positioned on each side of the liftgate. These balancers are complex systems that require a special arrangement of the vehicle body. automobile to accommodate them, when the tailgate is closed position. In addition, it is also necessary to equip the tailgate with a lock lock to keep locked the tailgate in the closed position on the vehicle.

Un tel système de retenue implique alors un surcoût de fabrication du véhicule. Un autre système de retenue<B>déjà</B> connu est un système mécanique du type compas qui ne permet pas de limiter la vitesse du mouvement du hayon lors de fermeture de l'ouverture dudit hayon. Pour maintenir le hayon en position fermée, est nécessaire d'équiper le hayon d'une serrure de verrouillage supplémentaire. outre, il également nécessaire de prévoir entre la caisse du véhicule et le hayon en position fermée, un logement pour contenir le compas. Enfin, le compas comporte deux pièces en mouvement l'une par rapport<B>à</B> l'autre, il faut alors prévoir régulièrement une lubrification desdites pièces, un réglage des forces de frottement entre lesdites pièces, de façon<B>à</B> compenser les usures de ces pièces, ce qui implique un entretien particulier de ce système de retenue et donc un surcoût. Such a restraint system then involves an additional cost of manufacturing the vehicle. Another retaining system <B> already </ B> known is a mechanical system of the compass type that does not limit the speed of movement of the tailgate when closing the opening of said tailgate. To keep the tailgate in the closed position, it is necessary to equip the tailgate with an additional lock lock. in addition, it is also necessary to provide between the vehicle body and the tailgate in the closed position, a housing for containing the compass. Finally, the compass comprises two parts moving relative to each other, it is then necessary to regularly provide a lubrication of said parts, an adjustment of the friction forces between said parts, so <B> > to </ B> compensate for the wear of these parts, which implies a particular maintenance of this restraint system and therefore an additional cost.

On connaît enfin comme système de retenue du hayon d'un véhicule automobile, simples butées mécaniques en position fermée ou ouverte du hayon. Ces butées mécaniques ne permettent pas de limiter la vitesse mouvement du hayon lors manceuvres dudit hayon. Elles doivent être assistées d'une serrure de verrouillage pour le verrouillage du hayon en position fermée ou ouverte. Finally, we know as the tailgate retaining system of a motor vehicle, simple mechanical stops in the closed or open position of the tailgate. These mechanical stops do not allow to limit the movement speed of the tailgate during maneuvers of said tailgate. They must be equipped with a lock lock to lock the tailgate in the closed or open position.

Afin pallier aux inconvénients précités de l'état de la techni la présente invention propose un nouveau hayon qui est équipé d'un système de retenue permettant lors des man#uvres du hayon de limiter sa vitesse mouvement, d'assurer butée en position ouverte du hayon, de maintenir le hayon en position fermée afin permettre le verrouillage du hayon dans cette position, tout en étant réalisable façon aisée et<B>à</B> moindre coût. In order to overcome the aforementioned drawbacks of the state of the art, the present invention proposes a new tailgate which is equipped with a restraint system which makes it possible, during the maneuvers of the tailgate, to limit its movement speed, to ensure that it is stopped in the open position of the vehicle. liftgate, to maintain the tailgate in the closed position to allow locking the tailgate in this position, while being achievable easy and <B> at </ B> lower cost.

Plus particulièrement, l'invention propose un hayon pour véhicule automobile caractérise en ce qu'il comporte<B>à</B> proximité d'au moins un de ses bords latéraux, un moyen de coopération par friction avec un moyen complémentaire prévu sur une partie fixe du véhicule, située en regard dudit bord latéral dudit hayon, assurant une retenue du hayon lors de son ouverture et de sa fermeture. More particularly, the invention proposes a tailgate for a motor vehicle characterized in that it comprises <B> at </ B> proximity to at least one of its lateral edges, a means of frictional cooperation with a complementary means provided on a fixed part of the vehicle, located opposite said lateral edge of said tailgate, ensuring retention of the tailgate during its opening and closing.

Avantageusement, selon l'invention, il est également prévu moyens de blocage et d'indexation du hayon en position ouverte et fermée associés auxdits moyens de coopération par friction. Advantageously, according to the invention, it is also provided means for locking and indexing the tailgate open and closed position associated with said friction cooperation means.

En outre, le hayon selon l'invention peut comporter un organe manoeuvre permettant verrouiller et de déverrouiller lesdits moyens blocage et d'indexation. In addition, the tailgate according to the invention may comprise a maneuver member for locking and unlocking said locking and indexing means.

Selon mode de réalisation préférentiel du hayon conforme<B>'</B> l'invention, il comporte<B>à</B> proximité d'un de ses bords latéraux, une couronne présentant une tranche avec une surface de friction positionnée en appui contre un taquet monté sur la partie fixe du véhicule automobile. According to the preferred embodiment of the hatchback conforming to the invention, it comprises a proximity to one of its lateral edges, a ring having a slice with a friction surface positioned. in support against a cleat mounted on the fixed part of the motor vehicle.

Selon mode de réalisation préférentiel, ladite couronne présente deux encoches él ignées l'une de l'autre d'une distance représentant un secteur circulaire d'environ quart de disque, et dans lesquelles est destiné<B>à</B> s'engager le taquet pour verrouiller le hayon en position fermée ou ouverte. According to a preferred embodiment, said ring has two notches elongated from each other by a distance representing a circular sector of approximately quarter disc, and in which is intended <B> to </ B> s' engage the latch to lock the liftgate in the closed or open position.

hayon<B>100</B> présente ici une forme rectangulaire avec deux bords latéraux <B>101,</B> comporte<B>à</B> proximité de chacun de ses bords latéraux 101,102 un moyen coopération par friction avec un moyen complémentaire prévus sur une partie fixe du véhicule<B>1</B> située en regard de chacun des bords latéraux dudit hayon. hatchback <B> 100 </ B> here has a rectangular shape with two side edges <B> 101, </ B> has <B> to </ B> proximity to each of its side edges 101,102 a means frictional cooperation with complementary means provided on a fixed part of the vehicle <B> 1 </ B> located opposite each of the lateral edges of said tailgate.

Ces moyens de coopération par friction assurent une retenue du hayon<B>100</B> lors de son ouverture et de sa fermeture. Selon l'exemple représenté sur la figure<B>1,</B> le hayon<B>100</B> comporte<B>à</B> proximité de chacun de ses bords latéraux<B>10 1, 1</B>02, une couronne<B>110,</B> et plus particulièrement une portion de couronne<B>110,</B> montée<B>à</B> basculement dans un logement solidaire de la ie fixe<B>300</B> du véhicule. These friction cooperation means ensure a restraint of the tailgate <B> 100 </ B> during its opening and closing. According to the example shown in Figure 1, the tailgate <B> 100 </ B> has <B> to </ B> near each of its side edges <B> 10 1, 1 </ B> 02, a crown <B> 110, </ B> and more particularly a portion of a crown <B> 110, </ B> rising <B> to </ B> tilting in a housing integral with the ie fixed <B> 300 </ B> of the vehicle.

Chaque couronne<B>110</B> présente une tranche<B>111</B> pourvue d'un revetement de friction sorte qu'elle forme une surface de friction positionnée en appui contre un taquet monté sur la partie fixe<B>300</B> du véhicule automobile. Each ring <B> 110 </ B> has a slice <B> 111 </ B> provided with a friction coating so that it forms a friction surface positioned in abutment against a cleat mounted on the fixed part <B > 300 </ B> of the motor vehicle.

Chaque taquet 200 est monté<B>à</B> coulissement dans une rainure 201, et est sollicite vers le bas sous l'action d'un moyen élastique du type ressort. Ainsi, il a tendance<B>à</B> s'engager dans une des encoches pour verrouiller le hayon en position fermée ou ouverte. Each cleat 200 is slidably mounted in a groove 201, and is urged downwardly by resilient means of the spring type. Thus, it tends to engage one of the notches to lock the tailgate in the closed or open position.

taquets et les encoches associés forment un moyen de blocage et d'indexation du hayon en positions ouverte et fermée. cleats and the associated notches form a locking and indexing means of the tailgate in open and closed positions.

peut être prévu un organe de manceuvre du type levier ou poignée (ici non représenté) apte<B>à</B> actionner chaque taquet 200, et plus particulièrement chaque ressort associé au taquet, pour le sortir d'une des encoches prévues chaque couronne<B>110</B> et libérer le hayon de sa position verrouillée. may be provided a lever or handle member (here not shown) adapted to <B> to </ B> operate each cleat 200, and more particularly each spring associated with the cleat, to remove it from one of the notches provided each crown <B> 110 </ B> and release the liftgate from its locked position.

Lorsque les taquets 200 sont sortis des encoches, ils prennent appui contre les couronnes et frottent contre la surface de friction des couronnes, cette coopération par frottement permettant de retenir le hayon lors de son ouverture de sa fermeture- les figures 2 et<B>3,</B> on a représenté un autre mode de réalisation hayon <B>100</B> conforme<B>à</B> l'invention, selon lequel, il est prévu au moins un disque<B>110' à</B> surface friction, et plus particulièrement une portion de disque<B>110',</B> monte sur une partie fixe<B>300</B> du véhicule automobile et au moins un élément de pression monté sur le hayon niveau d'un bord latéral 101,102, et venant en appui contre isque. Ici, l'élément de pression est un disque 120' plaqué contre le disque<B>à</B> surface friction 1101. When the cleats 200 are out of the notches, they bear against the crowns and rub against the friction surface of the crowns, this frictional cooperation to retain the tailgate when it opens its closure Figures 2 and <B> 3 , </ B> another embodiment of hatchback <B> 100 </ B> according to <B> to </ B> is shown, according to which, there is provided at least one disk <B> 110 ' to </ B> friction surface, and more particularly a portion of disk <B> 110 ', </ B> mounted on a fixed part <B> 300 </ B> of the motor vehicle and at least one pressure element mounted on the tailgate level of a side edge 101,102, and bearing against isque.
