Description

DISPOSITIF DE DEVERROUILLAGE AUTOMATIQUE DE CEINTURE DE SECURITE AUTOMATIC SEAT BELT RELEASE DEVICE
La présente invention concerne un appareil pour le déverrouilla ge automatique de la fixation à la carrosserie des ceintures de sécurité pour voitures automobiles.The present invention relates to an apparatus for the automatic unlocking of the attachment to the body of seat belts for motor cars.
Les ceintures de sécurité qui équipent actuellement les véhicules automobiles sont destinées à retenir le conducteur et les passagers sur leur siège, lors d'une collision avec un autre véhicule, ou avec un élément fixe disposé le long de la route, tel que maison, arbre, etc...The seat belts currently fitted to motor vehicles are intended to restrain the driver and passengers in their seats, in a collision with another vehicle, or with a fixed element placed along the road, such as house, tree , etc ...
Lorsque le choc se produit à vitesse assez réduite, dans le sens frontal, et que le véhicule demeure sur ses roues, le conducteur et les passagers gardent conscience et restent libres de leurs mouvements; ce qui leur permet de dégrafer leur ceinture euxmêmes et de sortir du véhicule , sans autre gêne qu'un léger contre-temps consécutif à la manoeuvre du dispositif d'ouverture de la ceinture.When the impact occurs at a fairly low speed, in the frontal direction, and the vehicle remains on its wheels, the driver and the passengers keep their consciousness and remain free to move; which allows them to unfasten their seatbelt themselves and to get out of the vehicle, without any other discomfort than a slight downtime following the operation of the belt opening device.
Il n ' en est malheureusement pas de même lorsque le choc se produit latéralement, frontalement à grande vitesse ou lorsque le véhicule s 'immobilise sur le côt é ou sur le dos, après avoir effectué un ou plusieurs tonneaux.Unfortunately, this is not the same when the impact occurs laterally, frontally at high speed or when the vehicle comes to rest on the side or on the back, after having rolled one or more barrels.
Dans ces cas, le conducteur et les passagers ont souvent perdu conscience et l ' intérieur du véhicule est peu accessible aux sauveteurs ; ce qui retarde considérablement la sortie des victimes du véhicule.In these cases, the driver and passengers have often lost consciousness and the interior of the vehicle is difficult for rescuers to access; which considerably delays the victims' exit from the vehicle.
La situation s ' aggrave encore lorsque le véhicule s ' enflamme, aussitôt après le choc , ou lorsque, par suite d 'une erreur de conduite ou d 'une mauvaise visibilité, celui-ci tombe dans un cours d ' eau, un canal , un lac ou un étang, car la panique s ' em pare alors des victimes qui ne parviennent plus à se libérer de leur ceinture et meurent ainsi brûlées ou noyées.The situation worsens further when the vehicle ignites, immediately after the impact, or when, as a result of a driving error or poor visibility, it falls into a stream, a canal, a lake or a pond, because panic is breaking out parries victims who can no longer free themselves from their belts and die burned or drowned.
Comme on le voit , les ceintures de sécurité sont excessivement dangereuses après l 'accident , lorsque celui-ci présente une certaine gravité.As can be seen, the seat belts are excessively dangerous after the accident, when it has a certain gravity.
Des dispositifs destinés à assurer l 'ouverture automatique à retardement de la ceinture ou le déverrouillage de sa fixation à la carrosserie, existent déjà. L 'un d'entre eux a été décrit dans la revue automobile, à la page 19 du N° 20 du II.05.78. D 'autres ont fait l 'objet d'une protection par brevets d'inventions, parmi lesquels on peut citer les brevets français N° 1.429.241, I.561.982, 2.199.073 , 2.317.947 et 2.323.404 et le brevet Américain 3. 235.930.Devices intended to ensure the automatic delay opening of the belt or the unlocking of its attachment to the bodywork already exist. One of them was described in the automobile review, on page 19 of N ° 20 of II.05.78. Others have been protected by invention patents, among which we can cite French patents N ° 1.429.241, I.561.982, 2.199.073, 2.317.947 and 2.323.404 and the patent American 3, 235,930.
Tous ces dispositifs, à l 'exception de celui décrit dans le brevet 2.323.404", sont incorporés au système d'ouverture de la ceinture et sont destinés à assurer l 'ouverture retardée de celle-ci, et tous ces dispositifs, sans exception, sont temporises à l'aide d'un mouvement d'horlogerie, compliqué et délicat, qui risque de se détériorer avant ou au moment du choc, ou lors de l 'incendie ou de l 'immersion du véhicule.All these devices, with the exception of that described in patent 2,323,404 ", are incorporated into the belt opening system and are intended to ensure the delayed opening thereof, and all these devices, without exception , are timed using a clockwork movement, complicated and delicate, which may deteriorate before or at the time of the impact, or during the fire or immersion of the vehicle.
L 'appareil selon 1 .invention a pour but de remédier à ces inconvénients. Celui-oi, en effet, est placé entre la ceinture et l 'un des points d'ancrage de celle-ci. Le système de retardement dont il est muni est constitué d'un dispositif à pompe, analogue à celui qui équipe certains matériels de photographie. La temporisation est réglable par simple rotation d'un doigt, dont l 'une des extrémités sert de butée à l 'axe du retardateur à pompe. La force de déclenchement de l 'ouverture de l 'appareil est réglable par l 'intermédiaire d'une pièce filetée manoeuvrable en rotation à partir de l 'extérieur. Le réarmement du doigt de verrouillage de la patte de fixation de la ceinture est facilité par l 'utilisation d 'un dispositif à double levier.The purpose of the apparatus according to 1 .invention is to remedy these drawbacks. This one, in fact, is placed between the belt and one of the anchor points thereof. The delay system with which it is equipped consists of a pump device, similar to that which equips certain photography equipment. The time delay is adjustable by simply rotating a finger, one end of which acts as a stop for the axis of the pump self-timer. The triggering force of the opening of the device is adjustable by means of a threaded part which can be operated in rotation from the outside. Resetting the locking finger of the belt lug is easier by the use of a double lever device.
Les avantages obtenus par cette invention consistent essentiellement en ce que le système de retardement utilisé est très sim pie et est pratiquement insensible aux chocs , à la température et au milieu dans lequel il est plongé; en ce que la temporisation est réglable, dans une plage importante, par simple rotation du doigt de retenue de l 'axe du dispositif de retardement à pompe; en ce que la force de déclenchement de l 'appareil est très facile à régler de l ' extérieur et en ce que l 'effort à exercer pour assurer le reverrouillage de la patte de fixation de la ceinture est très faible.The advantages obtained by this invention essentially consist in that the delay system used is very simple and is practically insensitive to shocks, to temperature and to the environment in which it is immersed; in that the time delay is adjustable, over a wide range, by simple rotation of the retaining finger of the axis of the pump delay device; in that the triggering force of the device is very easy to adjust from the outside and in that the effort to be exerted to relock the belt fastening lug is very low.
Cet appareil se distingue donc par une grande simplicité, une grande robustesse et une mise en oeuvre aisée.This device is therefore distinguished by great simplicity, great robustness and easy implementation.
D 'autres caractéristiques et avantages apparaîtront dans la description qui va suivre, donnée à titre d'exemple non limitatif, illustrée par un dessdn représentant seulement un mode de réalisation particulier.Other characteristics and advantages will appear in the description which follows, given by way of nonlimiting example, illustrated by a drawing representing only one particular embodiment.
La figure unique de ce dessin représente une vue de côté de l 'appareil réalisé conformément à la présente invention.The single figure of this drawing represents a side view of the apparatus produced in accordance with the present invention.
Cette figure représente un appareil pour le άéverrouillage automatique de la fixation à la carrosserie des ceintures de sécurite pour voitures automobiles comprenant essentiellement un corps I , un retardateur de pompe 2, muni d 'une tige centrale 2a, équipée d'un bouton de réarmement 2b, un doigt de déclenchement 3, muni d'un excentrique de réglage de temporisation 3a, d'une gorge de retenue 3b et d'une fente pour tournevis 3c, sollicité vers l ' ext érieur par tin ressort 4 et retenu par un anneau d'arrêt 5 ; une tige 6 , munie à l 'une de ses extrémités d 'un anneau de fixation 7 et à l 'autre extrémit é d 'un organe de verrouillage 8 , rappelé en permanence vers le doigt de déclenchement 3 par un ressort 9 réglable en tension par l'intermédiaire d'une vis 10; un doigt de verrouillage II traversant la patte de fixation 12 de la ceinture de sécurité, sollicité en permanence vers l 'extérieur .par un ressort 13, maintenu en position enfoncée par l'intermédiaire de deux palettes articulées 14 et 15, inversées l 'une par rapport à l 'autre et retenues l 'une contre l 'autre par un levier de déverrouillage 16, muni d'un crochet de retenue I6a articulé par rapport à un axe transversal 17, rappelé en permanence vers le doigt de verrouillage II par un ressort 18.This figure represents an apparatus for the automatic unlocking of the attachment to the bodywork of seat belts for motor cars essentially comprising a body I, a pump retarder 2, provided with a central rod 2a, equipped with a reset button 2b , a trigger finger 3, provided with a timing adjustment eccentric 3a, a retaining groove 3b and a slot for a screwdriver 3c, biased towards the outside by a spring 4 and retained by a ring of 'stop 5; a rod 6, provided at one of its ends with a fixing ring 7 and at the other end with a locking member 8, permanently returned towards the trigger finger 3 by a spring 9 adjustable in tension by means of a screw 10; a locking finger II passing through the fastening lug 12 of the seat belt, permanently urged outwards by a spring 13, held in the depressed position by means of two articulated pallets 14 and 15, one inverted relative to each other and held against one another by an unlocking lever 16, provided with a retaining hook I6a articulated with respect to a transverse axis 17, permanently returned to the locking finger II by a spring 18.
Comme on le voit, en se reportant à la figure, l 'appareil est retenu à la carrosserie, par l'anneau 7 et à la ceinture par le doigt de verrouillage II qui est maintenu en position par l 'intermédiaire des palettes articulées 14 et 15 et du levier de verrouillage 16. La tige centrale 2a du retardateur à pompe 2, préalablement armé, vient buter contre l 'excentrique de réglage de temporisation 3a qui est situé à l 'extrémité du doigt de déclenchement 3, lequel est retenu en position par l 'organe de verrouillage 8 relié à l 'anneau de fixation 7 par la tige 6.As can be seen, with reference to the figure, the device is retained on the bodywork, by the ring 7 and on the belt by the locking finger II which is held in position by means of the articulated pallets 14 and 15 and the locking lever 16. The central rod 2a of the pump retarder 2, previously cocked, abuts the eccentric timing adjustment 3a which is located at the end of the trigger finger 3, which is retained in position by the locking member 8 connected to the fixing ring 7 by the rod 6.
Lorsqu'un effort, dépassant la force de tarage du ressort 9 intervient, la tige 6 coulisse vers l 'extérieur en entraînant avec elle l 'organe de verrouillage 8 qui, en reculant, sort de la gorge 3b et libère le doigt de déclenchement 3 qui recule sous l 'effet de la tension du ressort 4 jusqu'à ce que l 'anneau d'arrêt 5 vienne buter contre le corps I. Ce recul du doigt de déclenchement 3 a pour effet de libérer la tige oentrale 2a du retardateur à pompe 2 et de permettre à l 'extrémité de celle-ci de venir prendre appui contre le levier de verrouillage 16 ; ce qui a pour effet de faire basculer le levier de verrouillage 16 autour de l 'axe 17, de faire reculer le crochet I6a, de libérer les palettes articulées 14 et 15 et de permettre le recul du doigt de verrouillage II sous l 'effet du ressort 13, ce qui libère la patte de fixation 12 de la ceinture et désolidarise celle-ci de la carrosεerie. On remarquera aussi que la temporisation, fonction de la distance qui sépare l 'extrémité de la tige 2a du levier de verrouillage 16 , peut être réglée par rotation du doigt de déclenchement 3; ce qui a pour effet de modifier la position angulaire de l 'ex centrique 3a contre lequel vient buter la tige 2a du retardateur à pompe 2.When a force, exceeding the setting force of the spring 9 intervenes, the rod 6 slides outwards, carrying with it the locking member 8 which, while moving back, leaves the groove 3b and releases the trigger finger 3 which moves back under the effect of the tension of the spring 4 until the stop ring 5 abuts against the body I. This retraction of the trigger finger 3 has the effect of releasing the central rod 2a from the retarder pump 2 and allow the end thereof to come to bear against the locking lever 16; which has the effect of tilting the locking lever 16 around the axis 17, making the hook I6a move back, releasing the articulated pallets 14 and 15 and allowing the locking finger II to move back under the effect of the spring 13, which frees the fastening lug 12 from the belt and separates the latter from the body. It will also be noted that the time delay, as a function of the distance which separates the end of the rod 2a from the locking lever 16, can be adjusted by rotation of the trigger finger 3; which has the effect of modifying the angular position of the ex centric 3a against which the rod 2a of the pump retarder 2 abuts.
La force de déclenchement peut être réglée en vissant ou dévissant la vis 10; ce qui a pour effet de bander plus ou moins le ressort 9.The tripping force can be adjusted by screwing or unscrewing the screw 10; which has the effect of more or less banding the spring 9.
Lors de l 'armement ou du réarmement de l 'appareil, la tige 2a du retardateur à pompe 2 doit être tout d 'abord ramenée vers l 'arrière, ce qui a pour effet d'emmagasiner l ' énergie nécessaire au prochain déverrouillage, puis le doigt de déclenchement 3 doit être enfoncé en bandant le ressort 4 jusqu'à ce que l 'organe de verrouillage 8 puisse pénétrer à nouveau dans la gorge de retenue 3b, Le levier de verrouillage 16 étant libéré, il suffit , pour assurer la fixation de la ceinture, d'introduire la patte 12 dans l 'appareil de façon que l 'axe de l 'orifice aménagé dans celle-ci corresponde avec celui du doigt de verrouillage II.. Il suffit alors de manoeuvrer successivement les palettes articulées 14 et 15 jusqu'à ce que l 'extrémité libre de la palette 15 vienne s 'enclencher derrière le bec I6a du levier de verrouillage 16; ce qui a pour effet de démultiplier l 'effort nécessaire au verrouillage.When arming or resetting the device, the rod 2a of the pump retarder 2 must first be brought back, which has the effect of storing the energy necessary for the next unlocking, then the trigger finger 3 must be pressed in by banding the spring 4 until the locking member 8 can re-enter the retaining groove 3b, the locking lever 16 being released, it suffices to secure it of the belt, to introduce the tab 12 into the device so that the axis of the orifice arranged in it corresponds to that of the locking finger II. It then suffices to maneuver successively the articulated pallets 14 and 15 until the free end of the pallet 15 comes to engage behind the spout I6a of the locking lever 16; which has the effect of increasing the effort required for locking.
L 'effort et le temps de déclenchement de l 'appareil étant réglables sur une large plage, il est possible de prérégler ceux-ci de façon à laisser la ceinture de sécurité jouer son rôle aussi longtemps que nécessaire, afin d' éviter, par exemple, un déverrouillage avant l 'immobilisation totale du véhicule, laquelle peut demander parfois 8 à 10 secondes; notamment en cas de sortie de la route, de télescopages en cascade , ou de tonneaux successifs. Dans des cas très particuliers, tels que ceux rencontrés par les cascadeurs professionnels, où la nature et l 'intensité du choc sont généralement déterminés à l 'avance, l 'appareil pourra, sans inconvénient, être réglé de façon que le déverrouillage se produise immédiatement après le choc, afin de libérer le conducteur le plus rapidement possible.The effort and the triggering time of the device being adjustable over a wide range, it is possible to preset these so as to let the seat belt play its role as long as necessary, in order to avoid, for example , unlocking before the vehicle comes to a complete stop, which can sometimes take 8 to 10 seconds; especially in case of off the road, cascading telescoping, or successive barrels. In very specific cases, such as those encountered by professional stuntmen, where the nature and intensity of the shock are generally determined in advance, the device can, without inconvenience, be adjusted so that unlocking occurs immediately. after the impact, in order to free the driver as quickly as possible.
L 'appareil, objet de l'invention, peut donc être utilisé dans tous les cas où l 'évacuation d'un véhicule, voire d'un aéronef, doit pouvoir s 'effectuer sans entrave aussitôt après l 'immobilisation qui suit un choc important.The device, object of the invention, can therefore be used in all cases where the evacuation of a vehicle, or even of an aircraft, must be able to be carried out without hindrance immediately after immobilization which follows a significant shock. .
Des applications particulièrement intéressantes existent dans les domaines automobile et aéronautique. Particularly interesting applications exist in the automotive and aeronautical fields.
