Description

Dispositif de montage d'une pédale sur un véhicule Device for mounting a pedal on a vehicle
La présente invention concerne un dispositif de montage d'une pédale, en particulier d'une pédale de frein ou de débrayage, d'un véhicule automobile.The present invention relates to a device for mounting a pedal, in particular a brake or clutch pedal, of a motor vehicle.
Lorsqu'un véhicule automobile subit un accident par un choc de sa partie avant contre un obstacle, notamment un choc frontal ou orienté vers l'arrière, il peut se produire un recul vers l'arrière du pédalier supportant notamment la pédale de frein. Or, le chauffeur, appuie en général fortement sur la pédale du frein au moment du choc. Cette pédale étant reliée au système de freinage mécanique ou hydraulique, pouvant inclure notamment un amplificateur de freinage, peut alors exercer une réaction importante sur pied du conducteur et lui faire subir des lésions physiologiques notamment dans sa cheville. Pour éviter ou limiter les blessures du chauffeur, une solution connue consiste à libérer les extrémités de l'axe de la pédale, lors de la déformation des flasques de la chape portant cet axe. La pédale n'oppose alors plus de résistance à une action du conducteur et vient se placer contre le plancher. La publication FR 2 780 172 décrit un dispositif de montage d'une pédale de frein dans lequel l'axe portant la pédale est sectionné par des couteaux qui se déplacent en cas de choc.When a motor vehicle undergoes an accident by a shock from its front part against an obstacle, in particular a frontal or rear-facing impact, there may be a backward movement of the crankset supporting in particular the brake pedal. However, the driver generally presses hard on the brake pedal at the time of impact. This pedal being connected to the mechanical or hydraulic braking system, which may include in particular a braking amplifier, can then exert a significant reaction on the driver's foot and subject him to physiological lesions in particular in his ankle. To avoid or limit injuries to the driver, a known solution consists in freeing the ends of the axis of the pedal when the flanges of the yoke carrying this axis are deformed. The pedal then no longer resists any action by the driver and comes to rest against the floor. The publication FR 2 780 172 describes a device for mounting a brake pedal in which the axis carrying the pedal is cut by knives which move in the event of an impact.
Cette solution impose des contraintes sur le choix des matériaux de l'axe de façon à assurer un cisaillement sous l'action des couteaux en cas de choc. En outre, le mouvement de l'axe, une fois sectionné, n'est pas imposé, et il est possible que l'axe vienne se bloquer contre la chape le portant, la pédale ne se rabattant alors pas correctement contre le plancher et venant opposer une réaction toujours importante à l'appui du conducteur.This solution imposes constraints on the choice of materials for the axis so as to ensure shearing under the action of the knives in the event of impact. In addition, the movement of the axis, once sectioned, is not imposed, and it is possible that the axis comes to lock against the yoke carrying it, the pedal then not folding down properly against the floor and coming oppose an always important reaction in support of the driver.
La présente invention vise à obtenir un dispositif de montage d'une • pédale permettant d'accroître la sécurité du chauffeur d'un véhicule /045750The present invention aims to obtain a device for mounting a pedal making it possible to increase the safety of the driver of a vehicle. / 045750

La présente invention sera mieux comprise à l'étude de dispositifs de montage d'une pédale d'un véhicule automobile, décrits à titre d'exemples non limitatifs et illustrés par le dessin sur lequel : - la figure 1 représente une vue latérale schématique du dispositif de montage d'une pédale d'un véhicule automobile selon la présente invention lors du fonctionnement habituel du véhicule,The present invention will be better understood from the study of devices for mounting a pedal of a motor vehicle, described by way of nonlimiting examples and illustrated by the drawing in which: - Figure 1 shows a schematic side view of the device for mounting a pedal of a motor vehicle according to the present invention during the normal operation of the vehicle,
- la figure 2 représente une section du dispositif de la figure 1, - la figure 3 représente une vue similaire à la vue dans le cas d'un choc frontal.FIG. 2 represents a section of the device of FIG. 1, - Figure 3 shows a view similar to the view in the event of a frontal impact.
Dans la suite de la description, l'axe de référence est l'axe longitudinal naturel d'un véhicule. Il est orienté vers l'avant du véhicule. Sur la figure 1 est représenté un dispositif de montage 1 d'une pédale de frein 2, située en aval, selon l'axe de référence, d'un tablier avant (non représenté) de l'habitacle du véhicule automobile.In the following description, the reference axis is the natural longitudinal axis of a vehicle. It is oriented towards the front of the vehicle. In Figure 1 is shown a mounting device 1 for a brake pedal 2, located downstream, along the reference axis, of a front bulkhead (not shown) of the passenger compartment of the motor vehicle.
Comme on le voit plus précisément sur la figure 2, la partie supérieure de la pédale 2 comprend un moyeu 5 qui est traversé par un axe transversal principal 6 dont les extrémités sont portées par des fiasques longitudinaux parallèles 7 d'un support 8 qui s'étend vers l'arrière à partir du tablier et qui est fixé à ce dernier de façon connue. Les flasques longitudinaux 7 présentent chacun une lumière 13, placée en vis-à-vis l'une de l'autre, s'étendant sensiblement horizontalement pour s'incurver vers le haut et vers l'arrière, et dans lesquelles peut coulisser l'axe transversal principal 6.As seen more precisely in FIG. 2, the upper part of the pedal 2 comprises a hub 5 which is crossed by a main transverse axis 6, the ends of which are carried by parallel longitudinal flanges 7 of a support 8 which s extends backwards from the apron and which is fixed to the latter in a known manner. The longitudinal flanges 7 each have a lumen 13, placed opposite one another, extending substantially horizontally to curve upwards and backwards, and in which the main transverse axis 6.
La pédale 2 est reliée à un organe d'amplification du freinage (non représenté) par l'intermédiaire d'une tige de liaison 3 articulée autour d'un axe 4. De façon classique, l'extrémité inférieure de la pédale 2 porte un patin 11 sur lequel le chauffeur du véhicule peut venir appuyer avec son pied de façon à rabattre le patin 11 en direction du tablier.The pedal 2 is connected to a braking amplification member (not shown) by means of a connecting rod 3 articulated around an axis 4. Conventionally, the lower end of the pedal 2 carries a pad 11 on which the driver of the vehicle can come to press with his foot so as to fold the pad 11 towards the deck.
Le dispositif 1 comprend un levier d'entraînement 12, que l'on peut voir plus précisément sur la figure 2. Le levier d'entraînement 12 se divise en deux unités de levier 17,21 identiques. Chaque unité de levier 17,21 présente deux zones formant un premier crochet 15 et un second crochet 16 en regard l'un de l'autre.The device 1 comprises a drive lever 12, which can be seen more precisely in FIG. 2. The drive lever 12 is divided into two identical lever units 17, 21. Each lever unit 17, 21 has two zones forming a first hook 15 and a second hook 16 facing each other.
Les unités de levier 17,21 sont en outre reliées aux flasques 7 du support 8 grâce à un axe transversal secondaire 14. /045750The lever units 17, 21 are also connected to the flanges 7 of the support 8 by means of a secondary transverse axis 14. / 045750
- 5 -- 5 -
Par ailleurs, chaque unité de levier 17,21 du levier de verrouillage 12 présente un bras 18 qui s'étend vers le haut à l'extérieur du support 8, en avant d'une zone d'appui 20 d'un support fixe 19 du véhicule, constitué par exemple par le support de la colonne de direction. En position normale de fonctionnement, la pédale 2 peut pivoter autour de l'axe transversal principal 6 qui est maintenu, dans les lumières 13, dans une position extrême orientée vers l'arrière du véhicule. L'axe transversal principal 6 est maintenu en position par une tension de serrage exercée sur l'axe transversal principal 6 (qui se compose, par exemple, d'un ensemble vis-écrou) et les premiers crochets 16 des unités de levier 17,21 du levier d'entraînement 12.Furthermore, each lever unit 17, 21 of the locking lever 12 has an arm 18 which extends upwards outside the support 8, in front of a support zone 20 of a fixed support 19 of the vehicle, constituted for example by the support of the steering column. In the normal operating position, the pedal 2 can pivot around the main transverse axis 6 which is maintained, in the slots 13, in an extreme position oriented towards the rear of the vehicle. The main transverse axis 6 is held in position by a tightening tension exerted on the main transverse axis 6 (which consists, for example, of a screw-nut assembly) and the first hooks 16 of the lever units 17, 21 of the drive lever 12.
En cas de choc frontal ou orienté vers l'arrière du véhicule contre un obstacle, le tablier se déplace vers l'arrière et entraîne avec lui en arrière le support 8 de la pédale 2. Ce faisant, le support fixe 19, qui normalement ne se déplace pas vers l'arrière ou plus tard au cours du choc ou beaucoup moins que le support 8, constitue par sa zone d'appui 20 une butée contre laquelle viennent en appui le bras 18 des unités de levier 17,21 du levier d'entraînement 12, ce qui provoque une rotation du levier d'entraînement 12 autour de l'axe secondaire 14, L'effort exercé sur le bras 18 pen et au premier crochet 15 de glisser par rapport au support 8, libérant ainsi la tension dans l'axe transversal principal 6. Cet axe transversal principal 6 se retrouve libre par rapport au support 8.In the event of a frontal impact or directed towards the rear of the vehicle against an obstacle, the apron moves towards the rear and drives with it behind the support 8 of the pedal 2. In doing so, the fixed support 19, which normally does not does not move rearward or later during the impact or much less than the support 8, constitutes by its support zone 20 a stop against which come to bear the arm 18 of the lever units 17, 21 of the lever d drive 12, which causes a rotation of the drive lever 12 about the secondary axis 14, The force exerted on the arm 18 pen and the first hook 15 to slide relative to the support 8, thereby releasing the tension in the main transverse axis 6. This main transverse axis 6 is found free relative to the support 8.
Lors de cette rotation, le levier d'entraînement 12 vient exercer un effort sur l'axe transversal principal 6 qui se déplace dans les lumières 13, sous l'action des seconds crochets 16 des unités de levier 17,21, en direction d'une position extrême située le plus en aval du véhicule.During this rotation, the drive lever 12 exerts a force on the main transverse axis 6 which moves in the slots 13, under the action of the second hooks 16 of the lever units 17, 21, in the direction of an extreme position located furthest downstream from the vehicle.
Le moment nécessaire au déverrouillage du levier d'entraînement 12 et de la mise en mouvement de l'axe transversal principal 6 est fonction de /045750The time required to unlock the drive lever 12 and set the main transverse axis 6 in motion is a function of / 045750

la nature des surfaces en contact et du couple de serrage appliqué sur l'axe transversal principal.the nature of the surfaces in contact and the tightening torque applied to the main transverse axis.
L'axe transversal principal 6 subit un déplacement selon une trajectoire imposée par la géométrie des lumières 13. Ce mouvement de recul de l'axe transversal principal 6, sachant que la pédale 2 est toujours liée à l'amplificateur de freinage par l'intermédiaire de l'axe 4, impose -un mouvement global de basculement de la pédale 2. Ce basculement a pour effet une avancée du patin 11 de la pédale 2. Cette avancée est fonction des dimensions des lumières 13. Le dispositif de montage 1 qui vient d'être décrit permet donc de transmettre normalement les efforts de commande par la pédale 2 en fonctionnement noπnal et en outre de faire avancer le patin 11 de la pédale 2 pour au moins partiellement soulager les efforts du pied sur la pédale 2 en cas de choc, garantissant ainsi une certaine protection du chauffeur contre des lésions physiologiques, notamment de ses chevilles.The main transverse axis 6 undergoes a displacement along a path imposed by the geometry of the lights 13. This backward movement of the main transverse axis 6, knowing that the pedal 2 is always linked to the braking amplifier via axis 4, imposes a global tilting movement of the pedal 2. This tilting has the effect of advancing the pad 11 of the pedal 2. This advance is a function of the dimensions of the lights 13. The mounting device 1 which comes to be described therefore makes it possible to transmit the control forces normally by the pedal 2 in normal operation and further to advance the pad 11 of the pedal 2 to at least partially relieve the efforts of the foot on the pedal 2 in the event of an impact , thus guaranteeing some protection for the driver against physiological damage, particularly to his ankles.
Selon une variante de l'invention, le levier d'entraînement 12 ne comporte qu'une seule unité de levier.According to a variant of the invention, the drive lever 12 has only one lever unit.
