DISPOSITIF ABSORBEUR DE CHOC
La présente invention concerne un dispositif absorbeur de choc.SHOCK ABSORBING DEVICE
The present invention relates to a shock absorbing device.
On sait que l'on cherche de plus en plus à protéger l'intérieur des habitacles des véhicules automobiles, afin de limiter pour les occupants les conséquences d'un accident. On est ainsi amené à introduire des dispositifs absorbeurs de choc en différents emplacements tels que les portières du véhicule ou les appui-tête des sièges. We know that we are increasingly seeking to protect the interior of motor vehicle interiors, in order to limit the consequences of an accident for occupants. It is thus necessary to introduce shock absorbing devices in different locations such as the vehicle doors or the headrests of the seats.
Par ailleurs, on cherche également à réduire le niveau sonore à l'intérieur de l'habitacle. On utilise notamment à cet effet des moquettes de sol. Un emplacement où une telle moquette est particulièrement utile pour ses effets acoustiques est en doublure du tablier séparant le compartiment moteur de l'habitacle. Furthermore, efforts are also being made to reduce the noise level inside the passenger compartment. In particular, floor carpets are used for this purpose. A location where such carpet is particularly useful for its acoustic effects is in the lining of the deck separating the engine compartment from the passenger compartment.
Or, ce tablier est également un élément de protection essentiel en cas de choc frontal puisqu'il prévient la pénétration d'éléments du moteur dans l'habitacle. Toutefois, dans le cas d'un tel choc frontal, il peut être amené à reculer brutalement et ainsi à exercer des efforts de compression considérables dans les jambes des passagers qui ont les pieds posés dessus. However, this apron is also an essential protective element in the event of a frontal impact since it prevents the penetration of engine elements into the passenger compartment. However, in the case of such a frontal impact, it may have to back off suddenly and thus exert considerable compressive forces in the legs of passengers who have their feet on it.
La présente invention repose sur l'idée d'utiliser le tapis de sol simultanément comme écran acoustique et comme absorbeur de choc. Plus particulièrement, elle vise à fournir un dispositif absorbeur de choc pouvant notamment, mais non exclusivement, être utilisé dans un tapis de sol destiné à recouvrir le tablier d'habitacle d'un véhicule automobile. The present invention is based on the idea of using the floor mat simultaneously as an acoustic screen and as a shock absorber. More particularly, it aims to provide a shock absorbing device which can in particular, but not exclusively, be used in a floor mat intended to cover the passenger compartment apron of a motor vehicle.
A cet effet, I'invention a pour objet un dispositif absorbeur de choc, caractérisé par le fait qu'il comprend au moins un ensemble d'éléments tubulaires disposés bout à bout, deux éléments adjacents ayant des sections différentes, et celui de ces deux éléments ayant la plus grande section étant susceptible de se briser le long de sa ligne de contact avec la paroi latérale extérieure de l'autre élément lorsqu'un effort de compression axiale de valeur prédéterminé est appliqué auxdits éléments pour les emboîter l'un dans l'autre de façon télescopique. To this end, the invention relates to a shock absorber device, characterized in that it comprises at least one set of tubular elements arranged end to end, two adjacent elements having different sections, and that of these two elements having the largest section being liable to break along its line of contact with the external side wall of the other element when an axial compression force of predetermined value is applied to said elements to fit them one into the other 'other telescopically.
Dans un mode de réalisation particulier, lesdits éléments tubulaires sont à section sensiblement circulaires. In a particular embodiment, said tubular elements are of substantially circular section.
On obtient alors un dispositif ayant une forme de type conique ou tronconique. Mais des sections de forme autre peuvent être envisagées. Par exemple, des éléments à section carrée donnent des dispositifs de forme de type pyramidal. This gives a device having a conical or frustoconical type shape. However, sections of other shapes can be envisaged. For example, elements with a square section give pyramid-shaped devices.
Chaque élément autre que les éléments d'extrémité peut avoir d'un de ses cotés un élément adjacent de section supérieure à la sienne, et de son autre coté un élément adjacent de section inférieure à la sienne. Each element other than the end elements may have on one of its sides an adjacent element with a cross section greater than its own, and on its other side with an adjacent element with a cross section less than its own.
Avec des éléments de section circulaire, le dispositif possède alors une forme de cône ou de tronc de cône. With elements of circular section, the device then has a shape of cone or truncated cone.
En variante, au moins un élément peut avoir d'un de ses coté deux éléments adjacents, I'un de section supérieure à la sienne, et l'autre de section inférieure à la sienne. As a variant, at least one element may have one of its sides two adjacent elements, one of section greater than its own, and the other of section less than its own.
On obtient alors des dispositifs dont les éléments sont plus ou moins imbriqués les uns dans les autres. On peut par exemple obtenir un cône inclus dans un tronc de cône, le cône et le tronc de cône ayant leur conicité de sens inverse, et la base du cône étant confondue avec la petite base du tronc de cône. We then obtain devices whose elements are more or less nested one inside the other. One can for example obtain a cone included in a truncated cone, the cone and the truncated cone having their conicity in opposite directions, and the base of the cone being confused with the small base of the truncated cone.
Avantageusement, au moins un élément possède une amorce de rupture le long de sa ligne de contact avec la paroi latérale extérieure de l'élément adjacent de section inférieure. Advantageously, at least one element has a rupture initiator along its line of contact with the external lateral wall of the adjacent element of lower section.
Avantageusement également, le dispositif selon l'invention est réalisé d'une seule pièce en matière plastique moulée. Advantageously also, the device according to the invention is made in one piece from molded plastic.
L'invention a également pour objet un revêtement de surface absorbeur d'énergie, notamment pour la protection des habitacles de véhicules automobile, caractérisé par le fait qu'il comprend au moins un dispositif tel que décrit ci-dessus, monté sur un matériau en feuille relativement rigide. The invention also relates to an energy-absorbing surface coating, in particular for the protection of the passenger compartments of motor vehicles, characterized in that it comprises at least one device as described above, mounted on a material made of relatively rigid leaf.
Le matériau en feuille précité peut notamment être constitué d'un complexe insonorisant à base de moquette etlou de "masse lourde" (feuille de matière plastique de haute densité) éventuellement accompagné de mousse ou de feutre. The aforementioned sheet material may in particular consist of a sound-absorbing complex based on carpet and / or "heavy mass" (sheet of high density plastic) possibly accompanied by foam or felt.
Ledit dispositif peut notamment être clipsé ou soudé sur le matériau en feuille, ou être réalisé d'une seule pièce, notamment par moulage, avec ce matériau. Said device can in particular be clipped or welded to the sheet material, or be made in one piece, in particular by molding, with this material.
Dans un mode de réalisation particulier, ledit dispositif est noyé dans une mousse plastique. In a particular embodiment, said device is embedded in a plastic foam.
On décrira maintenant, à titre d'exemple non limitatif, des modes de réalisation particulier de l'invention, en référence aux dessins schématiques annexés dans lesquels:
- la figure 1 est une vue en coupe axiale d'un dispositif absorbeur d'énergie selon l'invention;
- la figure 2 est une vue similaire à la figure 1 d'un autre mode de réalisation;
- la figure 3 est une vue en coupe transversale d'un tapis faisant usage d'un dispositif selon l'invention;
- la figure 4 est une vue de dessus d'un autre mode de réalisation de l'invention; et
- la figure 5 est une vue en coupe selon la ligne V-V de la figure 4.We will now describe, by way of nonlimiting example, particular embodiments of the invention, with reference to the appended schematic drawings in which:
- Figure 1 is an axial sectional view of an energy absorbing device according to the invention;
- Figure 2 is a view similar to Figure 1 of another embodiment;
- Figure 3 is a cross-sectional view of a mat making use of a device according to the invention;
- Figure 4 is a top view of another embodiment of the invention; and
- Figure 5 is a sectional view along line VV of Figure 4.
Comme montré aux figures 1 et 2, un dispositif 1 absorbeur d'énergie selon l'invention est composé d'une pluralité d'éléments tubulaires 2, disposés bout à bout, I'extrémité axiale 2a d'un élément 2 étant reliée à l'extrémité 2b d'un élément adjacent 2' de section inférieure, et son autre extrémité 2c étant reliée à l'extrémité 2d de l'autre élément adjacent 2" de section supérieure. Les éléments ont des sections variables de sorte qu'un élément particulier 2 possède d'un de ses cotés 2a un élément adjacent 2' de section inférieure, et de son autre coté 2c un élément 2" de section supérieure. As shown in Figures 1 and 2, an energy absorbing device 1 according to the invention is composed of a plurality of tubular elements 2, arranged end to end, the axial end 2a of an element 2 being connected to the 'end 2b of an adjacent element 2' of lower section, and its other end 2c being connected to the end 2d of the other adjacent element 2 'of upper section. The elements have variable sections so that one element particular 2 has on one of its sides 2a an adjacent element 2 'of lower section, and on its other side 2c an element 2 "of upper section.
Les éléments 2 sont ici circulaires, de sorte qu'ils forment des anneaux. Plus particulièrement, ces anneaux ont ici, en coupe axiale, une section rectangulaire. The elements 2 are here circular, so that they form rings. More particularly, these rings have here, in axial section, a rectangular section.
Dans le mode de réalisation de la figure 1, la section des éléments varie continûment le long de l'axe du dispositif qui, ainsi , se présente sous la forme générale d'un cône. In the embodiment of Figure 1, the section of the elements varies continuously along the axis of the device which, thus, is in the general form of a cone.
Dans le mode de réalisation de la figure 2, un élément intermédiaire 3 constitue une sorte de "point de rebroussement" ou la conicité s'inverse pour que le dispositif forme un tronc de cône extérieur 4 contenant un cône 5,
I'élément intermédiaire 3 formant la base du cône 5 et la petite base du tronc de cône 4. In the embodiment of FIG. 2, an intermediate element 3 constitutes a sort of "cusp" or the taper reverses so that the device forms an outer truncated cone 4 containing a cone 5,
The intermediate element 3 forming the base of the cone 5 and the small base of the truncated cone 4.
Comme montré à la figure 1, une amorce de rupture 10 peut être formée sous la forme d'une rainure pratiquée dans la surface d'extrémité 11 d'un élément, le long de la ligne de jonction entre cet élément de grande section et la surface latérale 12 de l'élément adjacent de plus faible section. As shown in FIG. 1, a breaking point 10 can be formed in the form of a groove formed in the end surface 11 of an element, along the junction line between this element of large section and the lateral surface 12 of the adjacent element of smaller section.
Lorsqu'un effort de compression axiale est exercé sur ces dispositifs, il se produit une rupture absorbeuse d'énergie, le long de la ligne de jonction entre un élément de grande section et la surface latérale de l'élément adjacent de plus faible section, cette rupture étant favorisée par l'amorce de rupture 10. Ainsi les différents éléments s'emboîtent progressivement les uns dans les autres de façon télescopique. When an axial compression force is exerted on these devices, an energy absorbing rupture occurs, along the junction line between an element of large section and the lateral surface of the adjacent element of smaller section, this rupture being favored by the initiation of rupture 10. Thus the various elements progressively fit into each other telescopically.
On observera qu'en choisissant convenablement les sections de rupture, on peut déterminer l'ordre dans lequel ces ruptures se produisent. It will be observed that by choosing the rupture sections properly, one can determine the order in which these ruptures occur.
C'est ainsi que dans un mode de réalisation du type de celui de la figure 1, les ruptures vont se propager du sommet du cône vers sa base, dans le sens où les surfaces des plans de rupture augmentent. Au contraire, dans un mode réalisation du type de celui de la figure 2, les ruptures se produiront sensiblement simultanément, les surfaces des plans de rupture étant sensiblement égales d'un élément à l'autre.Thus in an embodiment of the type of that of FIG. 1, the ruptures will propagate from the top of the cone towards its base, in the direction where the surfaces of the rupture planes increase. On the contrary, in an embodiment of the type of that of FIG. 2, the ruptures will occur substantially simultaneously, the surfaces of the rupture planes being substantially equal from one element to another.
Comme montré à la figure 3, des dispositifs absorbeurs d'énergie 1 selon l'invention peuvent être soudés ou fixés par des clips 10 à la surface d'une peau 11 en matière plastique relativement rigide pour former un tapis absorbeur d'énergie. Les dispositifs 1 sont ici noyés dans une mousse 12. As shown in FIG. 3, energy absorbing devices 1 according to the invention can be welded or fixed by clips 10 to the surface of a skin 11 made of relatively rigid plastic material to form an energy absorbing mat. The devices 1 are here embedded in a foam 12.
Le tapis ainsi obtenu peut être plaqué contre le tablier 13 de séparation du compartiment moteur de l'habitacle d'un véhicule automobile, et être à son tour revêtu d'une moquette 14 du coté habitacle. II fournit ainsi une protection contre les chocs exercés depuis l'avant du véhicule. The carpet thus obtained can be pressed against the apron 13 for separating the engine compartment from the passenger compartment of a motor vehicle, and in turn be covered with carpet 14 on the passenger side. It thus provides protection against shocks exerted from the front of the vehicle.
Dans le mode de réalisation des figures 4 et 5, un ensemble de dispositifs 20 absorbeurs d'énergie du type décrit ci-dessus, sont moulés d'une seule pièce avec une peau 21 à laquelle ils sont raccordés par leur base. Les dispositifs 20 sont ici disposés suivant des lignes en quinconce. In the embodiment of Figures 4 and 5, a set of energy absorbing devices 20 of the type described above, are molded in one piece with a skin 21 to which they are connected by their base. The devices 20 are here arranged in staggered lines.
La feuille ainsi obtenue peut à son tour entrer dans la composition d'un tapis insonorisant. The sheet thus obtained can in turn enter into the composition of a sound-absorbing carpet.
