Description

La présente invention concerne un dispositif de protection comprenant un casque et une coque amovible destinée à modifier l'aspect extérieur d'un casque.The present invention relates to a protective device comprising a helmet and a removable shell for changing the appearance of a helmet.

L'invention trouvera son application dans tout domaine nécessitant l'utilisation de dispositifs de protection pour la tête comme dans les sports mécaniques ou autres.The invention will find application in any field requiring the use of protective devices for the head as in motor sports or other.

Classiquement, pour modifier l'aspect extérieur du casque, on connaît l'application de peintures particulières. Mais cette solution n'est pas satisfaisante car généralement très coûteuse et peu durable car le casque subit de nombreux chocs abîmant la peinture.Conventionally, to modify the external appearance of the helmet, the application of particular paints is known. But this solution is not satisfactory because generally very expensive and not durable because the helmet undergoes many shocks damaging the paint.

Une autre solution consiste à recouvrir le casque d'un élément textile de la couleur, motif, texture souhaité. Le textile a la forme d'une housse munie d'un pourtour élastique de sorte à être maintenu sur le casque. Cependant, cette solution ne convient pas pour l'utilisation des casques lors de déplacements à vitesse élevée comme c'est le cas lors de courses de voitures, de motos, de ski etc. En effet dans ces situations, le casque et la housse sont soumis à de forts vents et des risques pour que la housse se décroche du casque existent. De plus, la housse n'épousant pas totalement la surface extérieure du casque, elle crée une prise au vent qui n'est pas souhaitable surtout lors de courses de vitesse. US 4,599,752 décrit un casque avec une coque amovible destinée à se fixer sur le casque.Another solution is to cover the helmet with a textile element of the desired color, pattern, texture. The textile is in the form of a cover provided with an elastic periphery so as to be held on the helmet. However, this solution is not suitable for the use of helmets when traveling at high speed as is the case during races of cars, motorcycles, skiing etc. Indeed in these situations, the helmet and the cover are subject to strong winds and risks for the cover comes off the helmet exist. In addition, the cover does not fully match the outer surface of the helmet, it creates a wind grip that is not desirable especially during speed races. US 4,599,752 describes a helmet with a removable shell to attach to the helmet.

Par conséquent, il existe le besoin de proposer un dispositif de protection dont on peut facilement modifier l'aspect extérieur, qui limite la prise au vent et résiste à des vitesses élevées.Therefore, there is the need to provide a protective device which can easily change the appearance, which limits wind resistance and withstands high speeds.

A cet effet, la présente invention concerne un dispositif de protection comprenant un casque et une coque amovible destinée à se fixer sur l'extérieur du casque. Le casque et la coque comprennent respectivement au niveau de leur pourtour frontal une rainure et une languette aptes à coopérer.To this end, the present invention relates to a protective device comprising a helmet and a removable shell for attachment to the outside of the helmet. The helmet and the shell respectively comprise at their front periphery a groove and a tongue adapted to cooperate.

Ainsi, la coque est fixement maintenue sur le casque notamment au niveau frontal où la prise au vent est la plus importante. Grâce au dispositif selon l'invention, aucune démarcation de relief n'est présente une fois le dispositif assemblé.Thus, the hull is fixedly held on the helmet including the frontal level where the wind resistance is the most important. Thanks to the device according to the invention, no relief demarcation is present once the device is assembled.

De plus, il peut être avantageux de prévoir des moyens de fixation postérieurs de la coque sur le casque. Ces moyens de fixation viennent renforcer la fixation de la coque sur le casque en supprimant tout jeu éventuel.In addition, it may be advantageous to provide posterior attachment means of the shell on the helmet. These fastening means reinforce the fixing of the shell on the helmet by removing any possible game.

D'autres buts et avantages apparaîtront au cours de la description qui suit d'un mode préféré de réalisation de l'invention qui n'en est cependant pas limitatif.Other objects and advantages will become apparent from the following description of a preferred embodiment of the invention which is not however limiting.

Il convient de rappeler que la présente invention concerne un dispositif de protection comprenant un casque et une coque amovible de protection destinée à se fixer sur le casque caractérisé par le fait que le casque comprend un pourtour frontal muni d'une rainure, avantageusement formée en avancée, apte à recevoir une languette formée, avantageusement en retrait, au niveau d'un pourtour frontal de la coque, préférentiellement de sorte que la rainure et la coque soient dans un même prolongement.It should be recalled that the present invention relates to a protective device comprising a helmet and a removable protective shell for attachment to the helmet characterized in that the helmet comprises a front circumference provided with a groove, advantageously formed in advanced , apt to receive a tongue formed, preferably recessed, at a frontal edge of the shell, preferably so that the groove and the shell are in the same extension.

Le dispositif de protection selon l'invention est destiné à la protection de la tête de l'utilisateur et comprend un casque, par exemple du type Jet et/ou type casque intégral.The protection device according to the invention is intended for the protection of the head of the user and comprises a helmet, for example of the Jet type and / or full-face helmet type.

Avantageusement, le casque 1 a une forme sensiblement sphérique recouvrant la totalité de la tête et possédant une ouverture frontale pour le visage. Le dispositif selon l'invention comprend aussi une coque 2 amovible destinée à s'adapter sur le casque 1. La coque 2 est avantageusement de forme complémentaire du casque. La coque 2 présente une certaine souplesse pour venir s'appliquer sur l'extérieur du casque 1.Advantageously, the helmet 1 has a substantially spherical shape covering the entire head and having a front opening for the face. The device according to the invention also comprises a removable shell 2 adapted to fit on the helmet 1. The shell 2 is advantageously of complementary shape of the helmet. The shell 2 has a certain flexibility to come to apply on the outside of the helmet 1.

Le casque 1 comprend une surface intérieure destinée à être au regard de la tête de l'utilisateur et une surface extérieure sur laquelle vient s'adapter la coque 2.The helmet 1 comprises an inner surface intended to face the user's head and an outer surface on which the shell 2 fits.

La coque 2 comprend elle aussi une surface intérieure destinée à venir au regard de la surface extérieure du casque 1 et une surface extérieure 5 dont l'aspect esthétique sera variable en fonction des goûts de l'utilisateur.The shell 2 also includes an inner surface intended to come in front of the outer surface of the helmet 1 and an outer surface 5 whose aesthetic appearance will be variable according to the tastes of the user.

De manière caractéristique, le casque 1 comprend au niveau du pourtour frontal une rainure et la coque 2 comprend elle-même au niveau de son pourtour frontal 6 une languette 4. La languette 4 fait partie intégrante de la coque 2.Characteristically, the helmet 1 comprises at the front periphery a groove and the shell 2 itself comprises at its front periphery 6 a tongue 4. The tongue 4 is an integral part of the shell 2.

Selon un premier mode réalisation, la languette 4 est formée en retrait de la surface extérieure 5 de la coque 2 de sorte à venir s'insérer dans la rainure 3 du casque 1 formée en avancée du casque.According to a first embodiment, the tongue 4 is formed recessed from the outer surface 5 of the shell 2 so as to be inserted into the groove 3 of the helmet 1 formed in advance of the helmet.

On entend par en retrait de la surface extérieure 5 de la coque 2 que la languette 4 n'est dans son prolongement mais décalée vers l'intérieur de la coque 2.Is meant by withdrawal from the outer surface 5 of the shell 2 that the tongue 4 is in its extension but shifted towards the inside of the shell 2.

De même, par le terme en avancée, on entend que la rainure 3 est incurvée vers l'extérieur du casque 1.Similarly, the term "advanced" means that the groove 3 is curved towards the outside of the helmet 1.

Ainsi, lorsque la coque 2 est placée sur le casque 1, la languette 4 s'insère dans la rainure 3 de sorte que la rainure 3 et la surface extérieure 5 de la coque 2 soient dans le même prolongement. Cette disposition permet d'éviter tout relief pouvant créer une prise au vent et donc des risques de décrochage de la coque 2 du casque 1.Thus, when the shell 2 is placed on the helmet 1, the tongue 4 is inserted into the groove 3 so that the groove 3 and the outer surface 5 of the shell 2 are in the same extension. This provision avoids any relief that can create a hold wind and therefore the risks of stalling the shell 2 of the helmet 1.

Selon un autre mode de réalisation (non représenté), la languette 4 est formée dans le prolongement de la coque 2 avec, ou non, continuité de l'épaisseur de la coque 2. La languette 4 est constituée par le bord de la coque 2. La languette 4-peut être d'épaisseur inférieure à l'épaisseur du reste de la coque 2.According to another embodiment (not shown), the tongue 4 is formed in the extension of the shell 2 with or without continuity of the thickness of the shell 2. The tongue 4 is constituted by the edge of the shell 2 The tongue 4 may be of thickness less than the thickness of the rest of the shell 2.

Selon une possibilité, la rainure 3 est formée dans la continuité du casque 1 de sorte à faire partie intégrante de celui-ci.According to one possibility, the groove 3 is formed in the continuity of the helmet 1 so as to be an integral part thereof.

Selon une autre possibilité préférentielle, la rainure 3 est formée par un élément indépendant et préférentiellement amovible du casque 1. La rainure 3 vient donc se positionner sur le pourtour frontal du casque 1 et reçoit la languette 4 de la coque 2.According to another preferred possibility, the groove 3 is formed by an independent and preferably removable element of the helmet 1. The groove 3 is thus positioned on the front periphery of the helmet 1 and receives the tongue 4 of the shell 2.

Selon cette possibilité, l'épaisseur de la rainure 3 correspond sensiblement à l'épaisseur du pourtour frontal 6 du casque 1 et à l'épaisseur de la languette 4 de la coque 2.According to this possibility, the thickness of the groove 3 substantially corresponds to the thickness of the front periphery 6 of the helmet 1 and to the thickness of the tongue 4 of the shell 2.

A titre d'exemple, la rainure 3 est un joint en élastomère ou plastique souple.For example, the groove 3 is an elastomer or flexible plastic seal.

Avantageusement, la languette 4 et la rainure 3 respectivement de la coque 2 et du casque 1 sont formées au niveau du pourtour frontal 6 et se prolongent au niveau de la zone jugulaire 9 du dispositif. On entend par zone jugulaire 9 la portion du dispositif au niveau des joues et du cou de l'utilisateur.Advantageously, the tongue 4 and the groove 3 respectively of the shell 2 and the helmet 1 are formed at the front periphery 6 and extend at the level of the chinstrap 9 of the device. The term jugular zone 9 the portion of the device at the cheeks and the neck of the user.

Il est très avantageux de prévoir que la rainure 3 et la languette 4 se poursuivent jusqu'au niveau de la zone jugulaire 9 qui est sensiblement proéminente et propice à la prise au vent. Ainsi, la fixation de la coque 2 sur le casque 1 est renforcée.It is very advantageous to provide that the groove 3 and the tongue 4 continue to the level of the chinstrap zone 9 which is substantially prominent and conducive to taking wind. Thus, the attachment of the shell 2 on the helmet 1 is reinforced.

L'intérieur de la coque 2 est avantageusement recouvert d'un matériau amortisseur 11 de fine épaisseur de sorte à ce qu'il n'y ait pas de jeu entre la coque 2 et le casque 1 une fois les deux pièces assemblées.The inside of the shell 2 is advantageously covered with a damping material 11 of thin thickness so that there is no clearance between the shell 2 and the helmet 1 once the two parts assembled.

Selon un mode de réalisation préféré, le dispositif selon l'invention comprend des moyens de fixation postérieurs de la coque 2 sur le casque 1. Ces moyens de fixation postérieurs sont avantageusement positionnés sur la face arrière du casque 1 dans sa partie inférieure sensiblement au niveau de la base du crâne.According to a preferred embodiment, the device according to the invention comprises rear fixing means of the shell 2 on the helmet 1. These posterior fixing means are advantageously positioned on the back side of the helmet 1 in its lower part substantially at the base of the skull.

Selon une variante, ces moyens de fixation postérieurs comprennent une encoche 7 au niveau du casque 1 apte à recevoir un tenon mobile 8 placé sur la coque 2. Ainsi, lorsque la coque 2 est placée sur le casque 1, le tenon 8 s'insère dans l'encoche 7 et par déplacement-du tenon mobile 8, celui-ci ne peut plus ressortir de l'encoche 7.According to one variant, these posterior fixing means comprise a notch 7 at the level of the helmet 1 capable of receiving a movable pin 8 placed on the shell 2. Thus, when the shell 2 is placed on the helmet 1, the pin 8 is inserted in the notch 7 and by displacement-of the movable pin 8, it can not emerge from the notch 7.

Selon une possibilité, le tenon mobile 8 est déplaçable par un bouton 12 placé sur la surface extérieure 5 de la coque 2 sur lequel l'utilisateur exerce une pression créant un déplacement d'un quart de tour du tenon mobile 8 qui ne peut alors plus sortir de l'encoche 7.According to one possibility, the movable pin 8 is movable by a button 12 placed on the outer surface 5 of the shell 2 on which the user exerts a pressure creating a shift of a quarter turn of the movable post 8 which can then no longer leave the notch 7.

Suivant une autre possibilité, le tenon mobile 8 est déplaçable en rotation selon un quart de tour par un mouvement effectué par l'utilisateur.According to another possibility, the movable pin 8 is rotatable in a quarter turn by a movement made by the user.

Ces moyens de fixation postérieurs présentent l'avantage de compléter la fixation de la coque 2 sur le casque 1 au niveau de l'arrière du dispositif.These posterior attachment means have the advantage of completing the fixing of the shell 2 on the helmet 1 at the rear of the device.

Classiquement, les casques de protection comprennent une visière de protection que l'utilisateur place devant son visage notamment devant ses yeux pour se protéger d'éventuelles projections.Conventionally, the protective helmets comprise a protective visor that the user places in front of his face, especially in front of his eyes to protect himself from possible projections.

Dans le dispositif selon l'invention, il est prévu des moyens d'attache 10a, 10b de la visière sur le dispositif. Ces moyens d'attache 10a, 10b sont positionnés au niveau de la zone temporale 13 du dispositif.In the device according to the invention, there is provided fastening means 10a, 10b of the visor on the device. These attachment means 10a, 10b are positioned at the temporal zone 13 of the device.

Au niveau du casque 1, les moyens d'attache 10a sont constitués par une dépression destinée à recevoir une saillie de forme complémentaire située au niveau de la coque 2.At the level of the helmet 1, the fastening means 10a consist of a depression intended to receive a projection of complementary shape situated at the level of the shell 2.

Au niveau de la coque 2, les moyens d'attache 10b sont constitués sur la surface extérieure d'une dépression formant sur la surface intérieure de la coque 2 une saillie venant s'insérer dans la dépression du casque 1.At the level of the shell 2, the fastening means 10b are constituted on the outer surface of a depression forming on the inner surface of the shell 2 a protrusion fitting into the depression of the helmet 1.

La visière de protection vient alors s'adapter par ses éléments d'attache au niveau des moyens d'attache 10b de la coque 2 notamment par un système de vis. Pour limiter les vibrations des éléments d'attache de la visière de protection sur la coque 2, un élément amortisseur peut être intercalé, par exemple une pièce de feutrine.The protective visor then adapts by its fastening elements at the fastening means 10b of the shell 2 in particular by a screw system. To limit the vibrations of the fastening elements of the protective visor on the shell 2, a damping element may be interposed, for example a piece of felt.

A titre d'exemple, la coque 2 est à base de polycarbonate permettant d'avoir une structure rigide et présentant à la fois une certaine souplesse laissant la possibilité à la coque 2 d'être légèrement déformée pour s'adapter sur le casque 1. Le casque 1 est quant à lui avantageusement en matériau composite à base de Carbone Kevlar® (marque déposée).For example, the shell 2 is based on polycarbonate to have a rigid structure and having both flexibility allowing the possibility to the shell 2 to be slightly deformed to fit on the helmet 1. The helmet 1 is advantageously made of composite material based on Carbon Kevlar® (registered trademark).

La rainure 3 a une profondeur d'environ un centimètre et une épaisseur d'environ trois millimètres. Elle est avantageusement entièrement formée dans la continuité du casque 1 de sorte à faire partie intégrante de celui-ci. Le casque 1 est de manière connue d'une épaisseur d'environ cinq millimètres comprenant à l'intérieur une protection standard pour la tête, homologuée aux normes en vigueur.The groove 3 has a depth of about one centimeter and a thickness of about three millimeters. It is advantageously entirely formed in the continuity of the helmet 1 so as to be an integral part thereof. The helmet 1 is in a known manner of a thickness of about five millimeters including inside a standard protection for the head, approved to the standards in force.

L'épaisseur de la coque 2 est d'environ trois millimètres. La hauteur de la languette est d'environ un centimètre équivalente à la profondeur de la rainure 3.The thickness of the shell 2 is about three millimeters. The height of the tongue is about one centimeter equivalent to the depth of the groove 3.

La surface extérieure 5 de la coque 2 peut être de couleur, de texture variables à souhait en fonction de l'aspect esthétique voulu.The outer surface 5 of the shell 2 may be of varying color and texture, depending on the desired aesthetic appearance.

La coque 2 contribue à l'amélioration de la protection de la tête de l'utilisateur par le dispositif.The shell 2 contributes to improving the protection of the user's head by the device.
