Description
La présente invention a pour objet un dispositif de protection d'une partie du corps humain ou animal contre les chocs, destiné plus particulièrement à la protection des jambes. The present invention relates to a device for protecting a part of the human or animal body against shocks, intended more particularly for the protection of the legs.
Actuellement les joueurs de football, par exemple, utilisent pour se protéger les jambes, notamment des coups directs portés sur l'arête des tibias, des protections comprenant une coque en matière plastique comportant sur sa face intérieure une couche de confort telle qu'une simple poche d'air. Currently football players, for example, use to protect the legs, including direct hits on the edge of the shins, protections including a plastic shell having on its inner side a layer of comfort such as a simple air pocket.
Toutefois le déplacement de la jambe d'un joueur d'un bon niveau athlétique, lors de la frappe d'une balle, peut atteindre des vitesses de l'ordre de 100 km/h, s'ajoutant à la vitesse de course du joueur, et les protections actuelles ne peuvent agir que comme un rempart protégeant uniquement le tibia au moment de l'impact des chaussures et surtout des crampons ou des pointes contre lesdites protections, le système osseux étant capable de recevoir et d'encaisser des ondes de chocs ou des secousses. However, the displacement of the leg of a player of a good athletic level, when striking a ball, can reach speeds of the order of 100 km / h, adding to the running speed of the player , and current protections can only act as a bulwark protecting only the shin at the time of the impact of the shoes and especially the spikes or spikes against said protections, the bone system being able to receive and collect shock waves or shaking.
Toutefois ces protections ne permettent d'éviter des répercussions secondaires sur l'organisme environnant, dues en particulier à la multiplicité des coups que reçoit un footballeur durant sa carrière professionnelle.However, these protections do not allow to avoid secondary effects on the surrounding body, due in particular to the multiplicity of blows that a player receives during his professional career.
Ces traumatismes affectent dune part les parties dites dures, se situant au dessus et en dessous de l'impact, telles que les articulations au niveau de la cheville ou du genou, et d'autre part les parties dites molles de la jambe telles que les muscles au repos, les veines, les artères ou encore les nerfs. These traumas affect on the one hand the so-called hard parts, located above and below the impact, such as the joints at the level of the ankle or the knee, and on the other hand the so-called soft parts of the leg such as the resting muscles, veins, arteries or nerves.
La présente invention a pour but de remédier à ce type d'inconvénients en proposant un dispositif de protection d'une partie du corps humain contre les chocs permettant d'absorber et de filtrer une onde de choc en évitant de ce fait des lésions internes. The present invention aims to overcome this type of disadvantages by providing a device for protecting a part of the human body against shocks for absorbing and filtering a shock wave thereby avoiding internal injuries.
A cet effet le dispositif selon l'invention comprend une coque relativement rigide conçue par ailleurs pour être résistante à des chocs violents et il se caractérise essentiellement en ce qu'il comprend, sur la face intérieure de ladite coque, à laquelle elles sont solidarisées par collage ou thermosoudage, au moins deux couches d'amortissement superposées en matériaux d'impédance mécanique adaptée, la valeur de l'impédance mécanique de chaque couche allant en décroissant depuis la couche externe, la plus éloignée du corps à protéger, dont l'impédance mécanique est inférieure à celle de la coque, jusqu'à la couche interne destinée à venir au contact dudit corps, cette dernière possèdant une impédance mécanique inférieure à celle du corps à protéger. For this purpose the device according to the invention comprises a relatively rigid hull designed otherwise to be resistant to violent shocks and it is essentially characterized in that it comprises, on the inner face of said shell, to which they are secured by bonding or heat-sealing, at least two superimposed damping layers of suitable mechanical impedance materials, the value of the mechanical impedance of each layer decreasing from the outer layer, the furthest from the body to be protected, whose impedance mechanical is less than that of the shell, to the inner layer intended to come into contact with said body, the latter having a mechanical impedance lower than that of the body to be protected.
Conformément à l'invention, la coque du dispositif de protection est réalisée en une matière plastique telle qu'un polycarbonate de densité 1,44 gm/cm3, et elle présente une épaisseur de l'ordre de 0,10 à 0,20 cm. According to the invention, the shell of the protective device is made of a plastic material such as a polycarbonate density 1.44 gm / cm3, and has a thickness of about 0.10 to 0.20 cm .
La couche d'amortissement externe, au contact de la coque, est réalisée en un matériau tel qu'un polyéthylène de densité 0,08 gm/cm3, ladite couche externe pouvant présenter une épaisseur de l'ordre de 0,10 à 0,20 cm. The outer cushioning layer, in contact with the shell, is made of a material such as a polyethylene of density 0.08 gm / cm3, said outer layer being able to have a thickness of about 0.10 to 0, 20 cm.
La couche d'amortissement interne, d'impédance mécanique la plus faible, est réalisée en un matériau tel qu'un polyuréthane de densité 0,03 gm/cm3, ladite couche interne pouvant présenter une épaisseur de l'ordre de 0,10 à 0,20 cm. The internal damping layer, with the lowest mechanical impedance, is made of a material such as a polyurethane with a density of 0.03 gm / cm3, said inner layer possibly having a thickness of about 0.10 to 0.20 cm.
Dans le cas de la protection de la jambe d'un individu, la partie inférieure du dispositif comprend deux parties renflées vers le bas par rapport à la ligne médiane dudit dispositif, en vue de protéger les parties dites molles, par exemple les muscles péroniers. In the case of the protection of the leg of an individual, the lower part of the device comprises two parts swollen downwardly relative to the median line of said device, to protect the so-called soft parts, for example the peroneal muscles.
Les avantages et les caractéristiques de la présente invention ressortiront plus clairement de la description qui suit et qui se rapporte au dessin annexé, lequel en représente un mode de réalisation non limitatif. The advantages and characteristics of the present invention will emerge more clearly from the description which follows and which refers to the appended drawing, which represents a non-limiting embodiment thereof.
Dans le dessin annexé
- la figure 1 représente une vue en plan schématique d'un mode de réalisation du dispositif selon l'invention placé sur un corps à protéger, en l'occurence la face antérieure de la jambe d'un individu. In the attached drawing
- Figure 1 shows a schematic plan view of an embodiment of the device according to the invention placed on a body to protect, in this case the front of the leg of an individual.
- la figure 2 représente une vue de face du dispositif selon l'invention mis à plat. - Figure 2 shows a front view of the device according to the invention laid flat.
- la figure 3 représente des graphiques indiquant les variations de l'intensité d'un choc en fonction du temps, enregistrées par des capteurs électroniques. FIG. 3 represents graphs indicating the variations of the intensity of a shock as a function of time, recorded by electronic sensors.
- la figure 4 représente schématiquement la position des capteurs électroniques mis en oeuvre pour enregistrer l'intensité des chocs dont les variations sont représentées sur les graphiques de la figure 3. FIG. 4 diagrammatically represents the position of the electronic sensors used to record the intensity of the shocks whose variations are represented on the graphs of FIG.
Si on se réfère à la figure 1 on peut voir que le dispositif selon l'invention, destiné à protéger la jambe 1 et le tibia 11 d'un footballeur, par exemple, comprend une coque 2 en matière plastique résistante, par exemple en polycarbonate, dont la face externe 21 est exposée aux chocs violents provenant de chaussures ou de leurs crampons. With reference to FIG. 1, it can be seen that the device according to the invention intended to protect the leg 1 and the tibia 11 of a footballer, for example, comprises a shell 2 made of a resistant plastic material, for example made of polycarbonate , whose outer face 21 is exposed to violent shocks from shoes or their crampons.
Deux couches d'amortissement 3 et 4 superposées et fabriquées chacune en un matériau de caractéristique mécanique adaptée recouvrent la coque rigide 2 à sa face interne. Two superimposed damping layers 3 and 4 each made of a suitable mechanical characteristic material cover the rigid shell 2 at its inner face.
La couche interne 3 au contact de la jambe 1 possède une impédance mécanique plus faible que celles de la couche externe 4, de la coque 2, et de la chair 12 de la jambe 1. The inner layer 3 in contact with the leg 1 has a lower mechanical impedance than those of the outer layer 4, the shell 2, and the flesh 12 of the leg 1.
Si on se réfère maintenant à la figure 2 on peut voir que le contour de la partie basse de la coque 2 comporte deux parties 21 et 22 renflées vers le bas de chaque coté de la ligne médiane 5 de la coque 2. Referring now to FIG. 2, it can be seen that the outline of the lower part of the shell 2 comprises two parts 21 and 22 bulged downwards on each side of the median line 5 of the shell 2.
De plus les couches d'amortissement 3 et 4 débordent autour de la coque 2 dont elles reproduisent les contours, en vue de protéger d'une part la face externe de la jambe 1 et notamment le muscle jambier antérieur porteur de la branche externe du nerf sciatique, qui, lorsqu'il est comprimé, entraîne une parésie du pied, et d'autre part la face interne de la jambe 1, notamment la veine saphène, siège de fréquents hématomes. In addition, the damping layers 3 and 4 project around the shell 2, the edges of which they reproduce, in order to protect on the one hand the external face of the leg 1 and in particular the anterior tibialis muscle bearing the external branch of the nerve. sciatica, which, when compressed, causes paresis of the foot, and secondly the inner face of the leg 1, including the saphenous vein, frequent haematomas.
Les deux parties renflées 21 et 22 quant à elles permettent de protéger les muscles péroniers qui, lorsqu ils sont touchés, entraînent une instabilité de la cheville. The two enlarged parts 21 and 22 for their part protect the peroneal muscles which, when touched, cause an instability of the ankle.
Si on se réfère à la figure 3, on peut voir deux graphiques 6 et 7 montrant les variations de l'intensité d'un choc en fonction du temps, enregistrées par des capteurs électroniques placés en des points A,B,C,D,E situés à des endroits différents dans l'os 11 de la jambe 1, les chocs étant induits par un impacteur 8 sur un dispositif de protection, le graphique 6 concernant un dispositif de protection de type connu et le graphique 7 un dispositif selon la présente invention. Referring to FIG. 3, two graphs 6 and 7 can be seen showing the variations in shock intensity as a function of time recorded by electronic sensors placed at points A, B, C, D, E located at different locations in the bone 11 of the leg 1, the shocks being induced by an impactor 8 on a protective device, the graph 6 concerning a known type of protection device and the graph 7 a device according to the present invention.
La figure 4 indique la position précise des points où sont détectées les variations dues au choc, les points A,B,C,D étant situés au voisinage de l'impact généré par l'impacteur 8 et le point E se trouvant à l'endroit le plus éloigné dans l'os 11. FIG. 4 shows the precise position of the points at which the variations due to the shock are detected, the points A, B, C, D being situated in the vicinity of the impact generated by the impactor 8 and the point E at the the farthest place in the bone 11.
Les courbes de pression des deux graphiques 6 et 7 montrent bien que la mise en oeuvre des couches d'amortissement 3 et 4 permet de diminuer l'intensité du choc induit par l'impacteur 8, cette atténuation de l'intensité étant surtout importante au niveau du point C. The pressure curves of the two graphs 6 and 7 clearly show that the implementation of the damping layers 3 and 4 makes it possible to reduce the intensity of the shock induced by the impactor 8, this attenuation of the intensity being especially important at level of point C.
Il va de soi que la présente invention ne saurait être limitée à la description qui précède d'un de ses modes de réalisation, susceptible de subir un certain nombre de modifications sans pour autant sortir du cadre de l'invention. It goes without saying that the present invention can not be limited to the foregoing description of one of its embodiments, capable of undergoing a number of modifications without departing from the scope of the invention.
