Description

1 Dispositif anti-pincement pour une porte coulissante d'un véhicule1 Anti-pinch device for a sliding door of a vehicle

automobile La présente invention concerne un dispositif anti-pincement pour une porte coulissante d'un véhicule automobile. Les véhicules automobiles comportent des ouvrants qui, dans certains cas, sont formés par des portes coulissantes. Lors de la fermeture de ces ouvrants, il peut se produire qu'un doigt ou une main d'un utilisateur soit coincé entre l'ouvrant et un élément fixe adjacent de la caisse du véhicule. Pour limiter ce genre de problème, les ouvrants de certains véhicules automobiles sont équipés d'un dispositif anti-pincement. C'est le cas des véhicules dont les ouvrants sont constitués par des portes coulissantes. A cet effet, on connaît des dispositifs anti-pincement qui permettent d'empêcher ou de limiter le coincement d'un doigt ou d'une main et qui sont formés par un profilé en caoutchouc conformé pour obstruer un espace sensiblement vertical entre la porte coulissante et l'élément adjacent de la caisse sur au moins une partie de la hauteur de l'ouverture, lorsque la porte coulissante a franchi au moins un cran de fermeture. Ce profilé permet d'adoucir le contact entre le corps étranger et la porte coulissante, lors de la fermeture de celle- ci. Dans le cas de portes coulissantes motorisées, on connaît des dispositifs anti-pincement comportant des moyens de détection de la présence d'un corps étranger entre la caisse du véhicule et la porte lors de sa fermeture qui déclanchent l'arrêt du moteur électrique entraînant par des moyens appropriés, ladite porte coulissante. Mais, ces dispositifs influent sur la cinématique même de la porte coulissante en la stoppant parfois de façon incongrue, par exemple, lors de la fermeture de la porte dans une pente ascendante ou lors d'un frottement anormal dû à la présence sur le rail notamment de cailloux. L'invention a pour but de proposer un dispositif de sécurité anti- pincement adapté aux portes coulissantes, simple à mettre en oeuvre et qui permet d'arrêter la fermeture de la porte coulissante dans un temps très bref. L'invention a donc pour objet un dispositif anti-pincement pour une porte coulissante d'un véhicule automobile, ladite porte étant déplaçable par 2906830 2 translation entre une position d'ouverture et une position de fermeture d'une ouverture pratiquée dans la caisse du véhicule, ladite caisse comportant un orifice de centrage d'un pion porté par la porte et destiné à pénétrer dans cet orifice en position de fermeture de la porte et ladite ouverture étant munie de 5 moyens de détection de la présence d'un corps étranger, caractérisé en ce que les moyens de détection sont reliés à des moyens de commande d'un organe de fermeture de l'orifice de centrage du pion pour bloquer la porte avant sa position de fermeture lors de la détection de la présence d'un corps étranger dans ladite ouverture.  The present invention relates to an anti-pinch device for a sliding door of a motor vehicle. Motor vehicles have openings which in some cases are formed by sliding doors. When closing these openings, it may occur that a finger or a hand of a user is stuck between the opening and an adjacent fixed element of the vehicle body. To limit this kind of problem, the opening of certain motor vehicles are equipped with an anti-pinch device. This is the case of vehicles whose doors are constituted by sliding doors. For this purpose, anti-pinch devices are known which prevent or limit the jamming of a finger or a hand and which are formed by a shaped rubber profile to obstruct a substantially vertical space between the sliding door and the adjacent element of the box over at least a portion of the height of the opening, when the sliding door has passed at least one closing notch. This profile makes it possible to soften the contact between the foreign body and the sliding door, when closing it. In the case of motorized sliding doors, anti-pinch devices are known comprising means for detecting the presence of a foreign body between the vehicle body and the door when it closes, which triggers the stopping of the electric motor driving by appropriate means, said sliding door. But, these devices affect the kinematics of the sliding door by stopping sometimes incongruously, for example, when closing the door in an upward slope or during abnormal friction due to the presence on the rail in particular pebbles. The invention aims to provide an anti-pinch safety device adapted to sliding doors, simple to implement and that stops the closing of the sliding door in a very short time. The invention therefore relates to an anti-pinch device for a sliding door of a motor vehicle, said door being movable by translating between an open position and a closed position of an opening made in the body of the vehicle. vehicle, said box having a centering hole of a pin carried by the door and intended to penetrate into this hole in the closed position of the door and said opening being provided with means for detecting the presence of a foreign body, characterized in that the detection means are connected to control means of a closing member of the pin centering hole for locking the door before its closed position when detecting the presence of a foreign body in said opening.

10 Selon d'autres caractéristiques de l'invention : - les moyens de détection comprennent un joint sensitif disposé sur le bord de l'ouverture de la caisse, - l'organe de fermeture de l'orifice est formé par un levier pivotant monté sur la caisse du véhicule et destiné à former une butée pour le pion porté 15 parla porte, - le levier pivotant est déplaçable par basculement entre une position active située devant l'orifice et une position passive escamotée dudit orifice au moyen d'une biellette articulée actionnée par les moyens de commande, 20 - le levier formant l'organe de fermeture est maintenu en position passive escamotée par un élément élastique de rappel, et - les moyens de commande de la biellette articulée sont formés par un actionneur électromagnétique raccordé aux moyens de détection. L'invention a également pour objet un véhicule automobile, 25 caractérisé en ce qu'il comporte au moins une porte coulissante équipée d'un dispositif anti-pincement tel que précédemment mentionné. L'invention sera mieux comprise à la lecture de la description qui va suivre, donnée à titre d'exemple et faite en se référant aux dessins annexés, sur lesquels : 30 -la Fig. 1 est vue schématique de côté d'une caisse d'un véhicule, comportant une porte coulissante équipée d'un dispositif anti-pincement, conforme à l'invention, 2906830 3 - la Fig. 2 est une vue schématique en coupe transversale de la porte coulissante dans sa position de fermeture sur la caisse du véhicule automobile, - la Fig. 3 est une vue schématique en coupe transversale de la 5 porte coulissante avec le dispositif anti-pincement dans la position de blocage de la porte, - la Fig. 4 est une vue schématique en perspective du dispositif anti-pincement dans sa position passive, et - la Fig. 5 est une vue schématique en perspective du dispositif 10 anti-pincement dans sa position active. Sur la Fig. 1, on a représenté schématiquement une porte coulissante 1 d'un véhicule automobile qui est montée déplaçable par translation sur une caisse 2 au moyen d'un système de type connu. Cette porte 1 est donc déplaçable par translation entre une position de fermeture d'une ouverture 3 15 pratiquée dans la caisse 2 du véhicule, comme représentée à la Fig. 2, et une position ouverte libérant l'ouverture 3 pour permettre à des utilisateurs d'accéder à l'intérieur du véhicule. Sur la Fig. 3, la porte coulissante 1 a été représentée en traits mixtes dans sa position ouverte et en trait plein dans une position intermédiaire 20 dans laquelle elle est bloquée avant sa fermeture complète par un dispositif antipincement conforme à l'invention du fait de la détection de la présence d'un corps étranger dans ladite ouverture 3. Ainsi que montrée sur les Figs. 2 et 3, la porte 1 comporte sur son bord avant la, un pion 5 destiné à pénétrer dans un orifice de centrage 6 25 ménagé sur le bord vertical de l'ouverture 3. Le bord périphérique de cette ouverture 3 est équipé de moyens de détection de la présence d'un corps étranger, tel qu'un doigt ou une main, et qui sont formés par un joint sensitif désigné dans son ensemble par la référence 7 formant également un joint d'étanchéité entre la porte 1 et la caisse 2, lorsque cette porte 1 est en position 30 de fermeture. Les moyens de détection constitués par le joint sensitif 7 sont reliés à des moyens 20 de commande d'un organe 10 de fermeture de l'orifice de 2906830 4 centrage 6 pour bloquer la porte 1 par l'intermédiaire du pion 5 avant sa position de fermeture lors de la détection de la présence d'un corps étranger dans l'ouverture 3 de la caisse 2. L'organe de fermeture 10 est formé par un levier 11, par exemple 5 en forme de L, monté pivotant sur la caisse 2 autour d'un axe 12. Le levier pivotant 11 est déplaçable par basculement autour de l'axe 12 entre une position passive escamotée de l'orifice 6 pour permettre au pion 5 de pénétrer dans cet orifice 6, ainsi que montré sur les Figs. 2 et 4 et une position active située devant cet orifice 6 pour former une butée empêchant au pion 5 de pénétrer dans cet 10 orifice 6, comme montré sur les Figs. 3 et 5, de façon à éviter la fermeture complète de la porte coulissante 1. Le basculement du levier 11 entre les deux positions est réalisé au moyen d'une biellette 15 articulée et actionnée par les moyens de commande 20 qui sont, de préférence, formés par un actionneur électromagnétique raccordé 15 au joint sensitif 7. Le levier 11 est maintenu en position passive, ainsi que montrée sur la Fig. 4, par un élément élastique de rappel 16 constitué par exemple par un ressort de traction ou par tout autre organe approprié. Pour cela, l'élément élastique de rappel 16 comporte une première extrémité reliée au levier 11 et une 20 seconde extrémité reliée à une patte fixe 17. Dans la position passive, le basculement du levier 11 est arrêté par une butée 18 et le levier 11 et l'axe 12 sont montés sur une platine 19 fixée par des moyens appropriés sur la caisse 2. Lorsque la porte coulissante 1 est ouverte et que le joint sensitif 7 25 n'est pas comprimé, l'actionneur électromagnétique 20 n'est pas alimenté et le levier 11 est maintenu dans sa position passive escamotée grâce à l'élément élastique de rappel 16. Dans cette position représentée sur les Figs. 2 et 4, l'orifice de centrage 6 est libéré ce qui permet au pion 5 de pénétrer dans ledit orifice de centrage 6 lors de la fermeture complète de la porte 1.According to other features of the invention: - the detection means comprise a sensing seal disposed on the edge of the opening of the body, - the closure member of the orifice is formed by a pivoting lever mounted on the vehicle body and intended to form an abutment for the pin carried 15para door, - the pivoting lever is movable by tilting between an active position in front of the orifice and a passive retracted position of said orifice by means of an actuated articulated rod by the control means, the lever forming the closing member is held in the passive position retracted by an elastic return element, and the control means of the articulated link are formed by an electromagnetic actuator connected to the detection means . The invention also relates to a motor vehicle, characterized in that it comprises at least one sliding door equipped with an anti-pinch device as previously mentioned. The invention will be better understood on reading the description which follows, given by way of example and with reference to the appended drawings, in which: FIG. 1 is a schematic side view of a body of a vehicle, comprising a sliding door equipped with an anti-pinch device according to the invention, FIG. 2 is a schematic cross-sectional view of the sliding door in its closed position on the body of the motor vehicle, FIG. 3 is a diagrammatic cross-sectional view of the sliding door with the anti-pinch device in the locked position of the door, FIG. 4 is a schematic perspective view of the anti-pinch device in its passive position, and FIG. 5 is a schematic perspective view of the anti-pinch device 10 in its operative position. In FIG. 1, schematically shows a sliding door 1 of a motor vehicle which is movably mounted by translation on a body 2 by means of a known type of system. This door 1 is movable by translation between a closed position of an opening 3 15 made in the body 2 of the vehicle, as shown in FIG. 2, and an open position releasing the opening 3 to allow users to access the interior of the vehicle. In FIG. 3, the sliding door 1 has been shown in phantom in its open position and solid line in an intermediate position 20 in which it is blocked before its complete closure by an anti-pinch device according to the invention because of the detection of the presence of a foreign body in said opening 3. As shown in Figs. 2 and 3, the door 1 has on its front edge, a pin 5 intended to penetrate into a centering orifice 6 25 formed on the vertical edge of the opening 3. The peripheral edge of this opening 3 is equipped with means of detecting the presence of a foreign body, such as a finger or a hand, and which are formed by a sensing gasket designated as a whole by the reference 7 also forming a seal between the door 1 and the body 2 when this door 1 is in the closed position. The detection means constituted by the sensing gasket 7 are connected to means 20 for controlling a closing member 10 of the centering orifice 6 to block the door 1 via the pin 5 before its position. closing when detecting the presence of a foreign body in the opening 3 of the body 2. The closure member 10 is formed by a lever 11, for example 5 L-shaped pivotally mounted on the body 2 around an axis 12. The pivoting lever 11 is movable by tilting about the axis 12 between a passive position retracted from the orifice 6 to allow the pin 5 to enter this orifice 6, as shown in Figs. 2 and 4 and an active position located in front of this orifice 6 to form a stop preventing the pin 5 from entering this orifice 6, as shown in FIGS. 3 and 5, so as to avoid the complete closing of the sliding door 1. The tilting of the lever 11 between the two positions is achieved by means of a link 15 articulated and actuated by the control means 20 which are, preferably, formed by an electromagnetic actuator connected to the sensing gasket 7. The lever 11 is held in the passive position, as shown in FIG. 4, by an elastic return member 16 constituted for example by a tension spring or by any other appropriate member. For this, the elastic return member 16 has a first end connected to the lever 11 and a second end connected to a fixed lug 17. In the passive position, the tilting of the lever 11 is stopped by a stop 18 and the lever 11 and the axis 12 are mounted on a plate 19 fixed by appropriate means on the body 2. When the sliding door 1 is open and the sensing gasket 7 25 is not compressed, the electromagnetic actuator 20 is not fed and the lever 11 is held in its retracted passive position thanks to the elastic return element 16. In this position shown in Figs. 2 and 4, the centering orifice 6 is released which allows the pin 5 to enter said centering hole 6 during the complete closing of the door 1.

30 Lorsqu'un obstacle est détecté par le joint sensitif 7 et que ce joint sensitif 7 est comprimé, l'actionneur électromagnétique 20 est excité ce qui a pour effet de déplacer la biellette articulée 15 selon l'axe A et de faire basculer 2906830 5 le levier 11 autour de l'axe 12 dans la position représentée sur les Figs.3 et 5 de façon à obturer l'orifice de centrage 6 pour empêcher au pion 5 de pénétrer dans cet orifice afin d'éviter une fermeture complète de la porte coulissante 1. Ainsi, la porte coulissante 1 est arrêtée avant qu'elle n'atteigne la 5 position de pincement dangereuse. Dès que le joint sensitif 7 ne détecte plus la présence d'un obstacle, l'actionneur électromagnétique 20 n'est plus excité et le levier 11 reprend, sous l'effet de l'élément élastique 16, sa position passive escamotée, comme montrée sur les Figs. 2 et 4, permettant ainsi au pion 5 de pénétrer dans 10 l'orifice de centrage 6 pour la fermeture de la porte coulissante 1. Le dispositif anti-pincement réagit rapidement car le temps dont on dispose pour empêcher la fermeture de la porte coulissante 1 est de l'ordre du centième de seconde et la course avant sa fermeture de la porte est très réduire de l'ordre du millimètre.When an obstacle is detected by the sensing gasket 7 and this sensing gasket 7 is compressed, the electromagnetic actuator 20 is energized which has the effect of moving the articulated link 15 along the axis A and tilting the air. the lever 11 about the axis 12 in the position shown in Figs.3 and 5 so as to close the centering hole 6 to prevent the pin 5 from entering this hole to prevent a complete closure of the door Thus, the sliding door 1 is stopped before it reaches the dangerous pinch position. As soon as the sensing gasket 7 no longer detects the presence of an obstacle, the electromagnetic actuator 20 is no longer energized and the lever 11 resumes, under the effect of the elastic element 16, its passive position retracted, as shown in Figs. 2 and 4, thus allowing the pin 5 to enter the centering hole 6 for closing the sliding door 1. The anti-pinch device reacts quickly because the time available to prevent the closing of the sliding door 1 is of the order of a hundredth of a second and the stroke before closing the door is very much reduced by a millimeter.

15 L'actionneur électromagnétique 20 est choisi en fonction de l'inertie du levier pivotant 11 pour que la mise en position de sécurité se fasse dans un délai assez court avant que la porte coulissante 1 n'atteigne une position dangeureuse. Un circuit électrique peut être intégré au dispositif pour neutraliser 20 l'alimentation de l'actionneur électromagnétique lorsque le joint sensitif est normalement comprimé en fin de fermeture de la porte coulissante. Le dispositif anti-pincement selon l'invention ne perturbe pas la cinématique de la porte lors de sa fermeture, mais empêche simplement son verrouillage. De plus, il peut s'appliquer aux portes coulissantes commandées 25 électriquement ou manuellement.The electromagnetic actuator 20 is chosen according to the inertia of the pivoting lever 11 so that the setting security position is made in a short time before the sliding door 1 reaches a dangerous position. An electrical circuit can be integrated in the device to neutralize the supply of the electromagnetic actuator when the sensing gasket is normally compressed at the end of closing of the sliding door. The anti-pinch device according to the invention does not disturb the kinematics of the door during its closing, but simply prevents its locking. In addition, it can be applied to sliding doors controlled electrically or manually.
