Description
La présente invention concerne un dispositif anti-pincement pour une porteThe present invention relates to an anti-pinch device for a door
battante d'un véhicule automobile. Les véhicules automobiles comportent des ouvrants formés par des portes battantes ou coulissantes et par des panneaux de coffre ou des hayons. 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 déclenchent l'arrêt du moteur électrique entraînant par des moyens appropriés, ladite porte coulissante. Mais, ces dispositifs connus sont difficilement transposables à des portes battantes. L'invention a pour but de proposer un dispositif de sécurité antipincement adapté aux portes battantes, simples à mettre en oeuvre, et qui permet d'arrêter la fermeture de la porte battante dans un temps très bref. L'invention a donc pour objet un dispositif anti-pincement pour une porte battante d'un véhicule automobile, ladite porte étant déplaçable par pivotement entre une position d'ouverture et une position de fermeture d'une ouverture pratiquée dans une caisse du véhicule et ladite ouverture étant munie de 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 blocage de la porte avant sa position de fermeture lors de la détection de la présence d'un corps étranger dans ladite ouverture. beating of a motor vehicle. Motor vehicles have openings formed by hinged or sliding doors and trunk panels or tailgates. 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 known devices are difficult to transpose to swing doors. The invention aims to provide an anti-pinch safety device adapted to swing doors, simple to implement, and which stops the closing of the swing door in a very short time. The invention therefore relates to an anti-pinch device for a swinging door of a motor vehicle, said door being pivotally movable between an open position and a closed position of an opening made in a vehicle body and said opening being provided with means for detecting the presence of a foreign body, characterized in that the detection means are connected to means for controlling a locking member of the door before its closed position during the detection the presence of a foreign body in said opening.

According to other characteristics of the invention: the blocking member acts on a door stop system; the detection means comprise a sensing gasket disposed on the edge of the opening of the box; locking member is formed by a pivoting lever mounted on the vehicle body and intended to cooperate with at least one roller mounted on the door and movable when closing the door on a rod of the door stop system, mounted on the body of the vehicle, the lever forming the locking member pivots about a substantially vertical axis between an advanced position of said roller on the rod before closing the door and a retracted position for closing said door; control means comprise an actuating system of a locking lever mounted on the vehicle body and movable by tilting about a substantially vertical axis between an active position for holding the locking lever in its advanced position to prevent the closing of the door by locking said at least roller and a retracted passive position releasing said locking lever for closing the door, - Actuating system is formed by at least one electromagnet connected to the detection means by an electric supply circuit, - the electric circuit comprises a contactor actuated by the lever forming the locking member, and - the lever forming a locking member and the locking lever are each held respectively in the advanced position and in a passive position by an elastic return element.
L'invention a également pour objet un véhicule automobile, caractérisé en ce qu'il comporte au moins une porte battante 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 : - la Fig. 1 est vue schématique en perspective d'une porte battante d'un véhicule automobile, équipée d'un dispositif anti-pincement conforme à l'invention, - la Fig. 2 est une vue schématique d'une partie de la porte en coupe horizontale dans sa position de fermeture, - la Fig. 3 est une vue schématique du dispositif anti-pincement dans la position de la porte fermée, - la Fig. 4 est une vue schématique du dispositif anti-pincement dans la position de la porte ouverte, - la Fig. 5 est une vue schématique du dispositif anti-pincement dans la position de blocage de la porte avant sa fermeture, et - la Fig. 6 est une vue schématique d'une partie de la porte en coupe horizontale dans la position de blocage avant sa fermeture. The invention also relates to a motor vehicle, characterized in that it comprises at least one swing 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 diagrammatic perspective view of a hinged door of a motor vehicle equipped with an anti-pinch device according to the invention; FIG. 2 is a schematic view of a part of the door in horizontal section in its closed position, FIG. 3 is a schematic view of the anti-pinch device in the closed door position; FIG. 4 is a schematic view of the anti-pinch device in the open door position; FIG. Figure 5 is a schematic view of the anti-pinch device in the locked position of the door before closing, and 6 is a schematic view of a portion of the door in horizontal section in the locking position before closing.
Sur la Fig. 1, on a représenté schématiquement une porte battante 1 d'un véhicule automobile qui est montée sur une caisse 2 de ce véhicule au moyen de charnières 3 à axe vertical. Cette porte 1 est déplaçable par pivotement au moyen de ces charnières 3 entre une position ouverte et une position de fermeture d'une ouverture 5 pratiquée dans la caisse 2 du véhicule. In FIG. 1, there is shown schematically a swing door 1 of a motor vehicle which is mounted on a body 2 of the vehicle by means of hinges 3 with a vertical axis. This door 1 is pivotally movable by means of these hinges 3 between an open position and a closed position of an opening 5 made in the body 2 of the vehicle.
Le bord périphérique de cette ouverture 5 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 6 formant également un joint d'étanchéité entre la porte 1 et la caisse 2, lorsque cette porte 1 est en position de fermeture. The peripheral edge of this opening 5 is equipped with means for detecting the presence of a foreign body, such as a finger or a hand, and which are formed by a sensory seal designated as a whole by the reference 6 also forming a seal between the door 1 and the body 2, when the door 1 is in the closed position.
De manière classique, la porte battante 1 est équipée d'un système d'arrêt de porte qui permet de maintenir la porte 1 ouverte dans une ou plusieurs positions intermédiaires, ainsi que dans sa position d'ouverture maximale. Ainsi que montré à la Fig. 2, ce système d'arrêt de porte comprend au moins un galet 7 et, de préférence, deux galets 7 opposés et symétriques, solidaires de la porte 1 et une tige 8 montée articulée au moyen d'un axe 9 sensiblement vertical sur la caisse du véhicule. De façon connue, les galets 7 roulent sur la tige 8 lors de l'ouverture de la porte et se positionnent dans des crans 8a ménagés sur cette tige 8 pour maintenir la porte dans une position intermédiaire d'ouverture ou dans sa position d'ouverture maximale. Conventionally, the swing door 1 is equipped with a door stop system which keeps the door 1 open in one or more intermediate positions, and in its maximum open position. As shown in FIG. 2, this door stop system comprises at least one roller 7 and, preferably, two opposed and symmetrical rollers 7 integral with the door 1 and a rod 8 mounted articulated by means of a substantially vertical axis 9 on the body of the vehicle. In known manner, the rollers 7 roll on the rod 8 during the opening of the door and are positioned in notches 8a formed on the rod 8 to hold the door in an intermediate opening position or in its open position Max.
Ainsi, les galets 7 se déplacent sur la tige 8 entre une première position représentée à la Fig. 3 correspondant à la position de la porte fermée et une seconde position représentée à la Fig. 4 correspondant à la position de la porte ouverte. Les moyens 6 de détection constitués par le joint sensitif sont reliés à des moyens 20 de commande d'un organe de blocage 10 de la porte 1 avant sa position de fermeture lors de la détection d'un corps étranger dans l'ouverture 5 de la caisse 2. Ainsi que montré sur les Figs. 2 et 3, l'organe de blocage 10 est formé par un levier 11 sensiblement horizontal et monté pivotant sur la caisse 2 du véhicule autour d'un axe 12 sensiblement vertical. Le levier 11 formant l'organe de blocage 10 agit sur le système d'arrêt de porte et coopère avec au moins un galet 7 de ce système d'arrêt de porte. Ce levier 11 pivote autour de l'axe 12 entre une position avancée représentée à la Fig. 4, qui correspond à l'une des positions d'ouverture de la porte 1 et une position reculée représentée à la Fig. 3 et qui correspond à la position de fermeture de la porte. Entre la position d'ouverture de la porte et la position de fermeture de cette porte, l'un des galets 7 entre en contact avec le levier 11 (Fig. 3) pour l'amener dans sa position reculée. Le levier 11 est maintenu dans sa position avancée par un organe élastique 13 de rappel qui est constitué dans l'exemple de réalisation représenté par les figures, par exemple, par un ressort de compression. Thus, the rollers 7 move on the rod 8 between a first position shown in FIG. 3 corresponding to the position of the closed door and a second position shown in FIG. 4 corresponding to the position of the open door. The detection means 6 constituted by the sensing gasket are connected to means 20 for controlling a blocking member 10 of the door 1 before its closed position when a foreign body is detected in the opening 5 of the crate 2. As shown in Figs. 2 and 3, the locking member 10 is formed by a substantially horizontal lever 11 and pivotally mounted on the body 2 of the vehicle about a substantially vertical axis 12. The lever 11 forming the locking member 10 acts on the door stop system and cooperates with at least one roller 7 of the door stop system. This lever 11 pivots about the axis 12 between an advanced position shown in FIG. 4, which corresponds to one of the open positions of the door 1 and a retracted position shown in FIG. 3 and which corresponds to the closed position of the door. Between the open position of the door and the closed position of this door, one of the rollers 7 comes into contact with the lever 11 (FIG 3) to bring it into its retracted position. The lever 11 is held in its advanced position by a resilient member 13 which is constituted in the embodiment shown in the figures, for example, by a compression spring.
Les moyens 20 de commande comprennent un système d'actionnement 21 d'un levier de verrouillage 22 sensiblement horizontal et monté pivotant autour d'un axe vertical 23 sur la caisse 2 du véhicule. Le levier 22 présente la forme générale d'un "L" et comporte une première branche 22a destinée à coopérer avec le levier 11 formant l'organe de blocage 10 et une seconde branche 22b destinée à coopérer avec le système d'actionnement 21 qui est constitué par au moins un électroaimant raccordé aux moyens 6 de détection, c'est à dire au joint sensitif, par un circuit d'alimentation électrique désigné par la référence 30. The control means 20 comprise an actuating system 21 of a substantially horizontal locking lever 22 and pivotally mounted about a vertical axis 23 on the body 2 of the vehicle. The lever 22 has the general shape of an "L" and comprises a first branch 22a intended to cooperate with the lever 11 forming the locking member 10 and a second branch 22b intended to cooperate with the actuating system 21 which is constituted by at least one electromagnet connected to the detection means 6, ie to the sensing gasket, by a power supply circuit designated by the reference 30.
Le levier de verrouillage 22 est, sous l'action du système d'actionnement 21, déplaçable autour de l'axe 23 entre une position passive escamotée libérant le levier 11 pour permettre à l'un des galets 7 de déplacer ce levier 11 jusqu'à sa position reculée pour permettre la fermeture de la porte, comme représentée à la Fig. 3, et une position active dans laquelle l'extrémité de la première branche 22a est disposée derrière le levier 11 pour maintenir ce levier 11 dans sa position avancée sur le trajet des galets 7 et, de ce fait, empêcher la fermeture de la porte 1, comme montrée à la Fig. 5. Le levier de verrouillage 22 est maintenu dans sa position passive par un élément élastique 25 de rappel constitué, par exemple, par un ressort de compression. The locking lever 22 is, under the action of the actuating system 21, movable about the axis 23 between a retracted passive position releasing the lever 11 to allow one of the rollers 7 to move the lever 11 to in its retracted position to allow the closing of the door, as shown in FIG. 3, and an active position in which the end of the first leg 22a is disposed behind the lever 11 to maintain the lever 11 in its advanced position in the path of the rollers 7 and, therefore, prevent the closing of the door 1 as shown in FIG. 5. The locking lever 22 is held in its passive position by a resilient biasing member 25 constituted, for example, by a compression spring.
Le circuit électrique 30 d'alimentation de l'électroaimant 21 est pourvu d'un contacteur 31 actionné par un prolongement 11 a du levier 11 pour couper la ligne d'alimentation de cet électroaimant 21 qui ne peut être excité, lorsque la porte 1 est fermée. En position de fermeture de la porte 1, comme représentée sur les Figs. 2 et 3, un galet 7 du système d'arrêt de porte arrivé en fin de course, presse le levier 11 à l'encontre de l'élément élastique 13. Dans cette position, le prolongement 11a du levier 11 n'agit pas sur le contacteur 31 ce qui a pour effet de couper l'alimentation de l'électroaimant 21. The electrical supply circuit 30 of the electromagnet 21 is provided with a contactor 31 actuated by an extension 11a of the lever 11 to cut the supply line of this electromagnet 21 which can not be excited, when the door 1 is closed. In the closed position of the door 1, as shown in Figs. 2 and 3, a roller 7 of the end of the door stop system, press the lever 11 against the elastic member 13. In this position, the extension 11a of the lever 11 does not act on the switch 31 which has the effect of cutting off the power supply of the electromagnet 21.
Dès l'ouverture de la porte 1, le levier 11 est repoussé par l'élément élastique 13 jusqu'à une butée 16, comme montré à la Fig. 4. Les galets 7 roulent le long de la tige 8 jusqu'à une position d'ouverture intermédiaire ou une position d'ouverture maximale. Dans cette position, le prolongement 11a du levier 11 appui sur le contacteur 31 qui ferme le circuit d'alimentation de l'électroaimant 21. Cet électroaimant 21 est branché sur deux lignes parallèles, l'une incluant le joint sensitif 6, l'autre passant par le contacteur 31. Le champ magnétique ainsi développé par l'électroaimant 21 attire la seconde branche 22b du levier 22 ce qui provoque le pivotement de ce levier 22 autour de l'axe 23, ainsi que montré à la Fig. 4. Ce levier 22 demeure dans cette position tant que la porte 1 reste ouverte. Ainsi, l'extrémité de la première branche 22a du levier 22 vient se placer derrière le levier 11 de manière à empêcher le recul total dudit levier 11. Lorsque la porte 1 se referme, l'un ou les galets 7 repoussent le levier 11 qui quitte la butée 16. Si aucun obstacle n'est détecté par le joint sensitif 6, le prolongement 11a du levier 11 ouvre le contacteur 31 et l'électroaimant 21 n'est plus alimenté. Par conséquent, le levier 22 n'est plus attiré par le champ magnétique de l'électroaimant 21 et se relève sous l'action de l'élément élastique 25. Le levier 11 peut alors continuer sa course, repoussé par le galet 7, qui retrouve sa position normale, la porte 1 est fermée. Si un obstacle déforme le joint sensitif 8, l'électroaimant 21 reste excité. La course du levier 11 est stoppée par son appui sur l'extrémité de la première branche 22a de levier 22 et le galet 7 en appui sur le levier 11 bloque ainsi la fermeture de la porte 1, comme représenté à la Fig. 5. Ainsi que montré à la Fig. 6, la porte 1 est stoppée avant sa fermeture complète, comme montrée par l'angle a qui est l'angle de sécurité avant la fermeture de la porte 1. Le dispositif anti-pincement réagit rapidement car le temps dont on dispose pour empêcher la fermeture de la porte est de l'ordre du centième de secondes et la course avant la fermeture de la porte est très réduite de l'ordre du millimètre. Upon opening of the door 1, the lever 11 is pushed by the elastic member 13 to a stop 16, as shown in FIG. 4. The rollers 7 roll along the rod 8 to an intermediate open position or a maximum open position. In this position, the extension 11a of the lever 11 bears on the contactor 31 which closes the supply circuit of the electromagnet 21. This electromagnet 21 is connected to two parallel lines, one including the sensing gasket 6, the other through the contactor 31. The magnetic field thus developed by the electromagnet 21 attracts the second leg 22b of the lever 22 which causes the pivoting of the lever 22 about the axis 23, as shown in FIG. 4. This lever 22 remains in this position as the door 1 remains open. Thus, the end of the first leg 22a of the lever 22 is placed behind the lever 11 so as to prevent the total recoil of said lever 11. When the door 1 is closed, one or the rollers 7 push back the lever 11 which leaves the stop 16. If no obstacle is detected by the sensing gasket 6, the extension 11a of the lever 11 opens the contactor 31 and the electromagnet 21 is no longer supplied. Therefore, the lever 22 is no longer attracted by the magnetic field of the electromagnet 21 and is raised under the action of the elastic element 25. The lever 11 can then continue its stroke, pushed by the roller 7, which returns to its normal position, door 1 is closed. If an obstacle deforms the sensing gasket 8, the electromagnet 21 remains energized. The stroke of the lever 11 is stopped by its support on the end of the first leg 22a lever 22 and the roller 7 bearing on the lever 11 thus blocks the closing of the door 1, as shown in FIG. 5. As shown in FIG. 6, the door 1 is stopped before its complete closure, as shown by the angle α which is the safety angle before closing the door 1. The anti-pinch device reacts quickly because the time available to prevent the closing of the door is of the order of a hundredth of a second and the stroke before closing the door is very small in the order of a millimeter.
L'électroaimant 21 est choisi en fonction de l'inertie du levier de verrouillage 22 pour que la mise en position de sécurité se fasse dans un délai assez court avant que la porte 1 n'atteigne une position dangeureuse. The electromagnet 21 is chosen according to the inertia of the locking lever 22 so that the setting security position is made in a relatively short time before the door 1 reaches a dangerous position.
Uni électroaimant surexcité, par exemple par décharge de condensateur, ce qui entraîne des champs magnétiques brefs et intenses, peut être utilisé. Le dispositif anti-pincement selon l'invention a pour avantage 5 d'avoir une consommation électrique et une usure mécanique négligeables, du fait qu'il est rarement sollicité. Par ailleurs, un circuit électrique capable de neutraliser l'alimentation de l'électroaimant lorsque le joint sensitif est normalement comprimé en fin de fermeture, peut être intégré au dispositif. 10 Uni-excited electromagnet, for example by capacitor discharge, resulting in short and intense magnetic fields, can be used. The anti-pinch device according to the invention has the advantage of having negligible electrical consumption and mechanical wear, because it is rarely used. Furthermore, an electrical circuit capable of neutralizing the supply of the electromagnet when the sensing gasket is normally compressed at the end of closure, can be integrated into the device. 10
