Abstract
Description
La présente invention a pour objet un dispositif d'escamotage d'un pédalier de véhicule automobile en cas de choc frontal. The present invention relates to a device for retracting a pedal unit of a motor vehicle in the event of a frontal impact.
Dans les véhicules automobiles, la colonne de direction et le pédalier de commande sont nécessairement placés en face du conducteur, leur support respectif se trouvant au droit d'un même plan vertical, longitudinal par rapport au véhicule. In motor vehicles, the steering column and the control pedal are necessarily placed in front of the driver, their respective support being located at the same vertical plane, longitudinal with respect to the vehicle.
Le support de la colonne de direction est habituellement fixé sous un caisson transversal d'auvent, tandis que le support du pédalier est fixé sur un tablier formant une séparation entre l'habitacle et le compartiment du moteur du véhicule automobile. The support of the steering column is usually fixed under a transverse awning box, while the support of the bottom bracket is fixed on an apron forming a separation between the passenger compartment and the engine compartment of the motor vehicle.
Généralement, le pédalier et son support constituent une entretoise entre le tablier et l'ensemble formé par la colonne de direction et par son support. Generally, the crankset and its support constitute a spacer between the apron and the assembly formed by the steering column and by its support.
Par conséquent, en cas de choc frontal du véhicule, les différents éléments situés dans le compartiment moteur reculent et tendent à repousser le support et le pédalier vers l'intérieur de l'habitacle dudit véhicule. Consequently, in the event of a frontal impact from the vehicle, the various elements located in the engine compartment move back and tend to push the support and the crankset towards the interior of the passenger compartment of said vehicle.
Compte tenu de l'architecture des véhicules, ce déplacement est transmis au support de la colonne de direction et, par conséquent, à l'ensemble colonne-volant ce qui peut occasionner des lésions particulièrement graves pour le conducteur. Given the architecture of the vehicles, this displacement is transmitted to the support of the steering column and, consequently, to the steering column assembly, which can cause particularly serious injuries to the driver.
On connaît des dispositifs qui permettent d'éviter la transmission du mouvement de déplacement du pédalier à l'ensemble colonne-volant et qui sont constitués par une plaque déformable sous l'action d'un effort prédéterminé et reliant le support du pédalier avec le support de la colonne de direction. Devices are known which make it possible to avoid the transmission of the movement of movement from the crankset to the steering column assembly and which consist of a plate deformable under the action of a predetermined force and connecting the support of the crankset with the support of the steering column.
Mais, ces dispositifs ne permettent pas d'éviter le recul du pédalier vers l'intérieur de l'habitacle ce qui peut entraîner des lésions au niveau des membres inférieurs du conducteur. However, these devices do not make it possible to avoid the backward movement of the crankset towards the interior of the passenger compartment, which can cause injuries to the driver's lower limbs.
L'invention a pour but d'éviter ces inconvénients. The invention aims to avoid these drawbacks.
L'invention a donc pour objet un dispositif d'escamotage d'un pédalier de véhicule automobile, du type comprenant un support dudit pédalier relié à un tablier de séparation entre le compartiment moteur et l'habitacle, caractérisé en ce que le support du pédalier est monté sur le tablier, déplaçable transversalement au véhicule entre une position d'utilisation et une position escamotée dudit pédalier, sous l'action d'un organe de commande déclenché par un détecteur de choc frontal dudit véhicule. The subject of the invention is therefore a device for retracting a motor vehicle crankset, of the type comprising a support for said crankset connected to a separation apron between the engine compartment and the passenger compartment, characterized in that the support for the crankset is mounted on the bulkhead, movable transversely to the vehicle between a position of use and a retracted position of said bottom bracket, under the action of a control member triggered by a frontal impact detector of said vehicle.
Selon d'autres caractéristiques de l'invention
- le support du pédalier est formé par deux flasques parallèles, reliés entre eux par une traverse et comportant chacun un coulisseau coopérant avec une glissière ménagée sur une platine solidaire dudit tablier,
- le support du pédalier est maintenu sur ladite platine, en position d'utilisation, par des éléments de fixation à résistance au cisaillement limitée et disposés au niveau d'au moins un coulisseau et une glissière correspondante,
- les éléments de fixation à résistance au cisaillement limitée sont formés par des rivets,
- l'organe de commande du déplacement du support dudit pédalier comprend un vérin pyrotechnique comportant, d'une part, un corps solidaire du tablier et, d'autre part, une tige mobile reliée à la traverse dudit support.According to other features of the invention
the pedal support is formed by two parallel flanges, interconnected by a cross member and each comprising a slide cooperating with a slide formed on a plate integral with said deck,
- the pedal support is held on said plate, in the use position, by fastening elements with limited shear strength and arranged at at least one slide and a corresponding slide,
- the fastening elements with limited shear strength are formed by rivets,
- The control member of the movement of the support of said bottom bracket comprises a pyrotechnic cylinder comprising, on the one hand, a body integral with the deck and, on the other hand, a movable rod connected to the cross member of said support.
D'autres caractéristiques et avantages de l'invention apparaîtront au cours de la description qui va suivre, donnée uniquement à titre d'exemple et faite en référence aux dessins annexés, sur lesquels
- la Fig. 1 est une vue schématique latérale d'un ensemble colonne de direction et volant et d'un pédalier équipé d'un dispositif d'escamotage selon l'invention,
- la Fig. 2 est une vue de face du pédalier représenté à la Fig. 1,
- la Fig. 3 est une vue en coupe selon la ligne 3-3 de la Fig. 2.Other characteristics and advantages of the invention will become apparent during the description which follows, given solely by way of example and made with reference to the appended drawings, in which
- Fig. 1 is a schematic side view of a steering column and steering wheel assembly and of a pedal unit equipped with a retracting device according to the invention,
- Fig. 2 is a front view of the crankset shown in FIG. 1,
- Fig. 3 is a sectional view along line 3-3 of FIG. 2.
Sur la Fig. 1, on a représenté schématiquement une colonne de direction 1 et un pédalier 2 relié à un tablier 3 constituant une séparation entre un habitacle 4 et un compartiment moteur 5. In Fig. 1, there is shown diagrammatically a steering column 1 and a bottom bracket 2 connected to an apron 3 constituting a separation between a passenger compartment 4 and an engine compartment 5.
La colonne de direction 1 est supportée par un support 10 et comporte, de manière classique, un axe supérieur 11 muni, à l'une de ses extrémités, d'un volant 12 et, à l'autre de ses extrémités, d'un cardan 13 de liaison avec un axe inférieur 14 qui traverse le tablier 3. The steering column 1 is supported by a support 10 and comprises, in a conventional manner, an upper axis 11 provided, at one of its ends, with a steering wheel 12 and, at the other of its ends, with a cardan 13 connecting with a lower axis 14 which crosses the deck 3.
L'axe inférieur 14 est pourvu d'un joint 15 au niveau de sa traversée dans le tablier 3. The lower axis 14 is provided with a seal 15 at its crossing in the deck 3.
Dans l'exemple de réalisation représenté sur les figures, le pédalier 2 comporte deux pédales, respectivement une pédale de frein 20 et une pédale d'embrayage 21. In the embodiment shown in the figures, the crankset 2 has two pedals, respectively a brake pedal 20 and a clutch pedal 21.
Le pédalier 2 est monté sur un support 22 qui est lui même monté sur le tablier 3 déplaçable transversalement au véhicule entre une position d'utilisation des pédales 20 et 21 et une position escamotée dudit pédalier 2, sous l'action d'un organe de commande 30 déclenché par un détecteur de choc frontal, non représenté. The pedal 2 is mounted on a support 22 which is itself mounted on the apron 3 movable transversely to the vehicle between a position of use of the pedals 20 and 21 and a retracted position of said pedal 2, under the action of a control 30 triggered by a frontal impact detector, not shown.
Ainsi que représenté sur les Figs. 2 et 3, le support 22 est formé par deux flasques parallèles, respectivement 23a et 23b, reliés entre eux par une traverse 24. As shown in Figs. 2 and 3, the support 22 is formed by two parallel flanges, respectively 23a and 23b, interconnected by a crosspiece 24.
Entre ces flasques 23a et 23b est également disposé un axe transversal 25 qui supporte les pédales 20 et 21. Between these flanges 23a and 23b is also disposed a transverse axis 25 which supports the pedals 20 and 21.
L'ensemble constitué par les flasques 23a et 23b, la traverse 24, l'axe 25 et les pédales 20 et 21 est monté coulissant transversalement par rapport au véhicule sur une platine 26 fixée sur le tablier 3 par des moyens appropriés, comme par exemple par soudage. The assembly constituted by the flanges 23a and 23b, the cross-member 24, the axis 25 and the pedals 20 and 21 is slidably mounted transversely relative to the vehicle on a plate 26 fixed on the deck 3 by suitable means, such as for example by welding.
Cette platine 26 est de forme générale rectangulaire et comporte sur chacun de ses bords longitudinaux une glissière, respectivement 27a et 27b, s'étendant sur toute la hauteur de ladite platine. This plate 26 is of generally rectangular shape and comprises on each of its longitudinal edges a slide, respectively 27a and 27b, extending over the entire height of said plate.
D'autre part, chaque flasque 23a et 23b est pourvu, sur sa face extérieure, d'un coulisseau, respectivement 28a et 28b, coopérant chacun avec une glissière, respectivement 27a et 27b. On the other hand, each flange 23a and 23b is provided, on its outer face, with a slide, respectively 28a and 28b, each cooperating with a slide, respectively 27a and 27b.
Le support 22 du pédalier est maintenu sur la platine 26 en position d'utilisation par des éléments de fixation 29 à résistance au cisaillement limitée. The support 22 of the crankset is held on the plate 26 in the position of use by fastening elements 29 with limited shear strength.
Ces éléments de fixation 29 sont disposés au niveau d'au moins une glissière 2a ou 27b et un coulisseau 28a ou 28b et sont constitués par exemple par des rivets. These fixing elements 29 are arranged at at least one slide 2a or 27b and a slide 28a or 28b and are constituted for example by rivets.
Dans l'exemple de réalisation représenté sur les figures, les éléments de fixation 29 sont au nombre de quatre, deux de ces éléments de fixation 29 traversant la glissière 27a et le coulisseau 28a correspondant et deux autres traversant la glissière 27b et le coulisseau 28b correspondant. In the embodiment shown in the figures, the fastening elements 29 are four in number, two of these fastening elements 29 passing through the slide 27a and the corresponding slide 28a and two others passing through the slide 27b and the corresponding slide 28b .
L'organe de commande du déplacement du support 22 du pédalier est formé par un vérin pyrotechnique 30 comprenant, d'une part, un corps 31 fixé sur le tablier 3 et une tige mobile 32 reliée à la traverse 24 dudit support 22. The member for controlling the movement of the support 22 of the crankset is formed by a pyrotechnic cylinder 30 comprising, on the one hand, a body 31 fixed to the deck 3 and a movable rod 32 connected to the crosspiece 24 of said support 22.
La tige 32 du vérin pyrotechnique 30 est reliée à la traverse 24 du support 22, par exemple par un ensemble vis-écrou 33. The rod 32 of the pyrotechnic cylinder 30 is connected to the cross-member 24 of the support 22, for example by a screw-nut assembly 33.
En utilisation normale, le support 22 et les pédales 20 et 21 se trouvent en position basse, comme représenté en traits continus sur la Fig. 1. In normal use, the support 22 and the pedals 20 and 21 are in the low position, as shown in solid lines in FIG. 1.
Lors d'un choc frontal du véhicule, le détecteur de choc actionne le vérin pyrotechnique 30 de façon à rétracter la tige 32. During a frontal impact on the vehicle, the shock detector actuates the pyrotechnic cylinder 30 so as to retract the rod 32.
Cette tige 32 exerce donc une traction sur l'ensemble du support 22, c'est à dire sur la traverse 24, les flasques 23a et 23b et les coulisseaux 28a et 28b ce qui provoque la rupture des éléments de fixation 29 à résistance au cisaillement limitée. This rod 32 therefore exerts traction on the whole of the support 22, that is to say on the cross-member 24, the flanges 23a and 23b and the slides 28a and 28b which causes the breaking of the fastening elements 29 with shear resistance. limited.
La rupture de ces éléments de fixation 29 libère le support 22 permettant ainsi la remontée du support 22 et des pédales 20 et 21 sous l'action du vérin pyrotechnique 30, comme représenté en traits mixtes sur la Fig. 1. The rupture of these fastening elements 29 releases the support 22 thus allowing the support 22 and the pedals 20 and 21 to be raised under the action of the pyrotechnic cylinder 30, as shown in phantom in FIG. 1.
La détection du choc et le déclenchement du vérin pyrotechnique 30 est réalisée par un dispositif électronique similaire au système de déclenchement des coussins gonflables et des ceintures à tendeur pyrotechnique couramment utilisé sur les véhicules automobiles. The detection of the shock and the triggering of the pyrotechnic cylinder 30 is carried out by an electronic device similar to the system for triggering the airbags and pyrotechnic tensioner belts commonly used on motor vehicles.
Selon les possibilités offertes par l'implantation des organes environnant le pédalier, différentes directions transversales d'escamotage de ce pédalier peuvent être envisagées transversales signifiant perpendiculaires à la direction longitudinale du véhicule. According to the possibilities offered by the implantation of the bodies surrounding the crankset, different transverse directions of retraction of this crankset can be envisaged transverse meaning perpendicular to the longitudinal direction of the vehicle.
Ainsi, au lieu d'être verticale comme décrit ci-dessus, la direction d'escamotage peut être notamment horizontale.Thus, instead of being vertical as described above, the retraction direction can be in particular horizontal.
La direction souhaitée est obtenue en orientant les glissières de liaison entre la platine et
L'amplitude du déplacement du pédalier est déterminée par la course disponible du vérin pyrotechnique et par la longueur de ces glissières.The desired direction is obtained by orienting the connecting slides between the plate and
The amplitude of the pedal movement is determined by the available stroke of the pyrotechnic cylinder and by the length of these slides.
Le dispositif d'escamotage selon l'invention permet donc d'éviter, lors d'un choc, le déplacement du pédalier vers l'intérieur de l'habitacle du véhicule et de limiter les interactions entre ce pédalier et la colonne de direction. The retracting device according to the invention therefore makes it possible to avoid, during an impact, the displacement of the crankset towards the interior of the vehicle cabin and to limit the interactions between this crankset and the steering column.
