Abstract
Description
La présente invention concerne un dispositif de contrôle du déplacement relatif de deux organes l'un par rapport à l'autre, notamment pour absorber une énergie de choc sur un organe de véhicule automobile et un système de fixation d'un équipement de véhicule automobile sur le reste de la structure de celui-ci, comportant un tel dispositif. The present invention relates to a device for controlling the relative displacement of two members with respect to each other, in particular for absorbing impact energy on a member of a motor vehicle and a system for fixing a piece of motor vehicle equipment to the rest of the structure thereof, comprising such a device.
Des contraintes de sécurité ont amené les constructeurs de véhicules automobiles à intégrer de plus en plus souvent des mécanismes d'absorption d'énergie de choc par exemple dans les systèmes de fixation des ensea- bles de colonne de direction de véhicules sur le reste de la structure de ceux-ci. Safety constraints have led motor vehicle manufacturers to integrate shock absorption mechanisms more and more often, for example, into systems for fastening steering column assemblies to vehicles on the rest of the structure of these.
Différents modes de réalisation de ces moyens d'absorption d'énergie de choc, ont été développés. Different embodiments of these shock energy absorption means have been developed.
C'est ainsi par exemple que ces moyens peuvent comporter des moyens à friction, frangibles ou encore à déformation, qui permettent de contrôler le déplaoeaent relatif de deux organes l'un par rapport à l'autre, pour absorber cette énergie de choc. Thus, for example, these means may include friction, frangible or even deformation means, which make it possible to control the relative displacement of two members relative to each other, to absorb this impact energy.
Cependant, tous ces dispositifs présentent un certain nombre d'inconvénients dans la mesure où il est extrêmement difficile de contrôler avec précision l'absorption d'énergie. However, all of these devices have a number of drawbacks since it is extremely difficult to precisely control energy absorption.
En effet, celle-ci est liée la plupart du temps aux tolérances de fabrication des pièces correspondantes et l'on conçoit que pour obtenir une bonne reproductibilité des caractéristiques d'absorption d'énergie lors d'une fabrication en série de ces pièces, ces tolérances de fabrication doivent être des plus réduites. Indeed, it is mostly linked to the manufacturing tolerances of the corresponding parts and it is understood that to obtain good reproducibility of the energy absorption characteristics during mass production of these parts, these manufacturing tolerances must be reduced as much as possible.
On conçoit alors que ceci augmente d'autant les coûts de fabrication de ces pièces. It is therefore understandable that this increases all the manufacturing costs of these parts.
Par ailleurs, certains de ces dispositifs présentent également des caractéristiques d' absorption défavorables en nécessitant une énergie relativement importante pour le début de leur fonctionnement. Furthermore, some of these devices also exhibit unfavorable absorption characteristics, requiring relatively high energy for the start of their operation.
On conçoit alors par exemple que ceci augmente d'autant les risques de blessures des occupants du véhicule. It will therefore be understood, for example, that this increases the risk of injury to the occupants of the vehicle all the more.
Le but de l'invention est donc de résoudre ces problèmes. The object of the invention is therefore to solve these problems.
A cet effet, l'invention a pour objet un dispositif de contrôle du déplacement relatif de deux organes l'un par rapport à l'autre, notamment pour absorber une énergie de choc sur un organe de véhicule automobile, caractérisé en ce qu'au moins l'un des organes est uni de moyens de coupe d'au moins une portion de l'autre organe, lors de leur déplacement relatif, afin de contrôler celuici par absorption d'énergie. To this end, the subject of the invention is a device for controlling the relative displacement of two members with respect to each other, in particular for absorbing impact energy on a member of a motor vehicle, characterized in that at at least one of the members is combined with means for cutting at least a portion of the other member, during their relative displacement, in order to control this by energy absorption.
Selon un mode de réalisation, les moyens de coupe comprennent au moins une douille reliée à un organe et disposée dans une lumière de l'autre organe, la douille comportant des arêtes de coupe des bords de la lumière lors de leur déplacement relatif. According to one embodiment, the cutting means comprise at least one socket connected to a member and arranged in a lumen of the other member, the socket having cutting edges of the edges of the lumen during their relative displacement.
Selon un autre aspect, l'invention a également pour objet un système de fixation d'un équipement de véhicule automobile, sur le reste de la structure de celui-ci, caractérisé en ce qu'il comporte un dispositif tel que décrit précédemment. According to another aspect, the invention also relates to a system for fixing a motor vehicle equipment, to the rest of the structure thereof, characterized in that it comprises a device as described above.
L'invention sera mieux comprise à la lecture de la description qui va suivre, donnée uniquement à titre d'exemple et faite en se référant aux dessins annexés, sur lesquels
- la Fig.l représente une vue de côté en coupe d'un exemple de réalisation d'un dispositif de contrôle selon l'invention;
- la Fig.2 représente une vue de dessus de l'exemple de réalisation du dispositif représenté sur la figure 1; et
- la Fig.3 représente une vue schéppatique illustrant le fonctionnement du dispositif de contrôle selon l'invention.The invention will be better understood on reading the description which follows, given solely by way of example and made with reference to the accompanying drawings, in which
- Fig.l shows a side view in section of an embodiment of a control device according to the invention;
- Fig.2 shows a top view of the embodiment of the device shown in Figure 1; and
- Fig.3 shows a scheppatic view illustrating the operation of the control device according to the invention.
Ainsi qu'on peut le voir sur ces figures, un dispositif de contrôle selon l'invention permet de contr- ler le déplacement relatif de deux organes l'un par rapport à 1' autre, notamment pour absorber une énergie de choc sur un organe d'un véhicule automobile. As can be seen in these figures, a control device according to the invention makes it possible to control the relative movement of two members relative to one another, in particular for absorbing impact energy on a member of a motor vehicle.
Dans l'exemple de réalisation représenté sur ces figures, on a illustré l'utilisation de ce dispositif de contrôle dans un système de fixation d'un ensemble de colonne de direction de véhicule automobile, sur le reste de la structure de celui-ci. In the embodiment shown in these figures, the use of this control device has been illustrated in a system for fixing a motor vehicle steering column assembly to the rest of the structure thereof.
Sur ces figures, le reste de la structure du véhicule est désigné par la référence générale 1. In these figures, the rest of the vehicle structure is designated by the general reference 1.
Dans cet exemple de réalisation, cette structure de véhicule comporte un trou taraudé 2 dans lequel est engagée une vis 3 portant une douille 4. In this exemplary embodiment, this vehicle structure comprises a tapped hole 2 in which is engaged a screw 3 carrying a socket 4.
Cette douille est engagée dans une lumière 5, par exemple d'une plaque 6 reliée à l'ensemble de colonne de direction pour assurer l'accrochage de celui-ci sur le reste de la structure du véhicule. This socket is engaged in a slot 5, for example of a plate 6 connected to the steering column assembly to ensure the attachment thereof on the rest of the vehicle structure.
Comme on peut le voir plus clairement sur la figure 2, la plaque 6 comporte par exemple deux lumières parallèles 5 et 7 dans lesquelles sont engagées des douilles respectivement 4 et 8. As can be seen more clearly in FIG. 2, the plate 6 comprises for example two parallel slots 5 and 7 in which sockets 4 and 8 are engaged respectively.
Ces douilles comportent avantageusement des arêtes de coupe des bords des lumières correspondantes lors de leur déplacement relatif afin de contrôler celuici par absorption d'énergie. These sockets advantageously comprise cutting edges of the edges of the corresponding slots during their relative displacement in order to control this by energy absorption.
On conçoit en effet comme on peut le voir sur ces figures, que les arêtes de coupe de la douille 4, désignées par exemple par les références 4a et 4b, présentent un écartement supérieur à celui des bords de la lumière correspondante 5. It can in fact be seen, as can be seen in these figures, that the cutting edges of the socket 4, designated for example by the references 4a and 4b, have a spacing greater than that of the edges of the corresponding lumen 5.
En cas de choc sur la plaque 6 et donc sur l'ensemble de colonne de direction, tendant à déplacer ceux-ci dans le sens indiqué par la flèche D sur la figure 1, on conçoit que les arêtes des douilles vont couper les bords des lumières correspondantes lors du déplacement de la plaque, afin de contrôler ce déplacement par absorption d'énergie. In the event of an impact on the plate 6 and therefore on the steering column assembly, tending to move them in the direction indicated by the arrow D in FIG. 1, it can be seen that the edges of the bushings will cut the edges of the corresponding lights during the movement of the plate, in order to control this movement by energy absorption.
On conçoit alors que ce contrôle et cette absorption d'énergie peuvent être réglés par exemple en dimensionnant de façon déterminée, 1 'épaisseur de la plaque ou l'épaisseur de matériau coupée ou encore en sélectionnant le matériau utilisé pour la fabrication de la plaque ou le nombre de douilles et de lumières utilisé, etc.. It can therefore be seen that this control and this energy absorption can be adjusted for example by dimensioning in a determined manner, the thickness of the plate or the thickness of material cut or else by selecting the material used for the manufacture of the plate or the number of sockets and lights used, etc.
Bien entendu, différents modes de réalisation de ce dispositif de contrôle peuvent être envisagés et celuici peut être utilisé pour contrôler le déplacement relatif de deux organes quelconques, l'un par rapport à l'autre, dans la mesure où au moins l'un des organes est nuni de moyens de coupe d'au moins une portion de l'autre organe, lors de leur déplacement relatif afin de contrôler celuici par absorption d'énergie. Of course, different embodiments of this control device can be envisaged and this can be used to control the relative movement of any two organs, one with respect to the other, insofar as at least one of the organs is provided with means for cutting at least a portion of the other organ, during their relative displacement in order to control this by energy absorption.
En effet, au moins l'un des organes dont il y a lieu de contrôler le déplacement peut être aluni de n'im- porte quels moyens de coupe appropriés engagés par exemple dans un simple trou de l'autre organe, ces moyens de coupe étant adaptés pour couper 1 'autre organe ou au moins une portion de celui-ci, lors de leur déplacement relatif. In fact, at least one of the members whose movement has to be controlled can be provided with any suitable cutting means engaged for example in a simple hole in the other member, these cutting means being adapted to cut one other member or at least a portion thereof, during their relative movement.
I1 va de soi également que bien que dans les figures on ait illustré un exemple d'un système de fixation d'un ensemble de colonne de direction de véhicule sur le reste de la structure de celui-ci, d'autres équipements de celui-ci peuvent également être fixés grâce à un tel dispositif. It also goes without saying that although in the figures an example of a system for fixing a set of vehicle steering column to the rest of the structure thereof has been illustrated, other equipment thereof. these can also be fixed using such a device.
C'est ainsi par exemple que les pare-chocs du véhicule peuvent egalement être fixés sur le reste de la structure du véhicule, grâce à de tels dispositifs. Thus, for example, the vehicle bumpers can also be fixed to the rest of the vehicle structure, thanks to such devices.
