Description

Enveloppe interchangeable pour casques et casques munis d'une telle enveloppe, permettant d'atténuer les effets traumatisants des chocs rotationnels. Interchangeable shell for helmets and helmets provided with such an envelope, to mitigate the traumatic effects of rotational shocks.
La présente invention concerne une enveloppe interchangeable pour casques, cette enveloppe et les casques qui en sont munis permettant d'atténuer les effets traumatisants des chocs rotationnels. D'une manière générale, l'invention s'applique à tous casques dont le port est obligatoire ou fortement recommandé, pour la pratique de toutes activités ludiques ou professionnellesThe present invention relates to an interchangeable casing for helmets, this casing and the helmets that are equipped to mitigate the traumatic effects of rotational shocks. In general, the invention applies to all helmets whose wearing is mandatory or highly recommended, for the practice of any recreational or professional activities
(cyclisme, surf des neiges, spéléologie, lutte contre les incendies, ...) nécessitant l'usage d'un élément de protection de la tête appelé communément « casque ».(cycling, snowboarding, caving, firefighting, ...) requiring the use of a head protection element commonly called "helmet".
Elle s'applique, en particulier, aux casques de motocyclistes, et plus particulièrement encore aux casques de motocyclistes du type couramment désignés par le nom de "jet".It applies, in particular, to motorcycle helmets, and more particularly to motorcycle helmets of the type commonly referred to as "jet".
Elle vise aussi les casques, en particulier les casques de motocyclistes, faisant application de cette enveloppe interchangeable.It also targets helmets, especially motorcycle helmets, applying this interchangeable envelope.
Les casques du genre "jet" sont notamment remarquables en ce qu'ils comportent une coque rigide enveloppante conformée pour protéger à la fois le le crâne et la nuque, des personnes qui en sont coiffées, la nuque étant considérée comme étant la partie postérieure du cou disposée au-dessous de l'occiput et comprenant les vertèbres cervicales.The helmets of the "jet" type are notably remarkable in that they comprise a rigid enveloping shell shaped to protect both the skull and the nape of the neck, of persons who are wearing them, the nape being considered as being the posterior part of the neck disposed below the occiput and including the cervical vertebrae.
Il est connu de recouvrir un casque avec un élément rapporté sur lequel est représentée une illustration inspirée par des thèmes variés : réalistes, fantastiques, romantiques, etc. Cette technique n'atténue pas les effets des chocs rotationnels.It is known to cover a helmet with a reported element on which is represented an illustration inspired by various themes: realistic, fantastic, romantic, etc. This technique does not mitigate the effects of rotational shocks.
Par exemple, le document WO - 2007/018.536 décrit une housse décorative en tissu se fixant sur le casque par l'intermédiaire de son bord élastique, ou encore, le document US - 2007/0.107.112 décrit une enveloppe décorative réalisée en matière plastique élastique et se fixant sur le casque par effet d'élasticité. Selon cette technique, les enveloppes, avant tout décoratives, sont effectivement interchangeables mais ne permettent pas d'atténuer les effets traumatisants des chocs rotationnels. Elles présentent également d'autres inconvénients non négligeables. En effet :For example, the document WO-2007 / 018.536 describes a fabric decorative cover attached to the helmet by means of its elastic edge, or the document US-2007 / 0.107.112 describes a decorative envelope made of plastic elastic and attaching to the helmet by elasticity effect. According to this technique, the envelopes, primarily decorative, are indeed interchangeable but do not mitigate the traumatic effects of rotational shocks. They also have other significant disadvantages. Indeed :
- elles n'assurent pas un contact intime de la couverture décorative souple et de la surface de la calotte externe rigide du casque coiffée par ladite couverture ;they do not ensure an intimate contact of the flexible decorative covering and the surface of the rigid outer cap of the helmet capped by said cover;
- cette absence de contact intime peut provoquer la formation de plis ou boursoufflures sur la surface externe du casque en nuisant ainsi gravement à l'esthétique de ces derniers.- This lack of intimate contact can cause the formation of folds or blisters on the outer surface of the helmet, thus seriously affecting the aesthetics of the latter.
Dans le document WO - 03/005844, est décrit un casque de protection comprenant une coque présentant une surface orientée vers l'intérieur qui, en cours d'utilisation, est tournée vers la tête d'un utilisateur de casque, et une surface orientée vers l'extérieur, qui en cous d'utilisation, est tournée du coté opposé à la tête de l'utilisateur, et une enveloppe extérieure qui recouvre une partie au moins de la surface tournée vers l'extérieur de la coque. Le casque de protection comprend encore des moyens de rupture pour attacher de façon fixe l'enveloppe extérieure au reste du casque, en un ou plusieurs emplacements. Lorsque les moyens de rupture cèdent à un ou plusieurs emplacements la force reçue amène la partie au moins de l'enveloppe extérieure qui reçoit la force à se déplacer par rapport à la coque d'une manière analogue à celle du mouvement de protection du cuir chevelu humain par rapport au crâne.WO-03/005844 discloses a protective helmet comprising a shell having an inward facing surface which, in use, is facing the head of a helmet user, and a surface oriented outwardly, which in use, is turned on the opposite side to the user's head, and an outer casing which covers at least a portion of the surface facing the outside of the shell. The protective helmet further comprises breaking means for fixedly attaching the outer shell to the rest of the helmet in one or more locations. When the rupture means yield at one or more locations, the force received causes the at least part of the outer casing which receives the force to move relative to the shell in a manner similar to that of the scalp protection movement. human in relation to the skull.
Le casque décrit dans ce document n'est pas un casque du type « jet » c'est à dire que ce casque permet seulement une couverture du crâne de l'utilisateur, mais qu'il n'est pas conformé pour assurer une couverture et une protection de la nuque de celui-ci. Il s'agit donc d'un casque d'un genre différent de celui qui est spécialement visé par la présente invention.The helmet described in this document is not a "jet" type helmet, that is to say that this helmet only allows coverage of the skull of the user, but that it is not conformed to provide coverage and a protection of the neck of it. It is therefore a helmet of a different kind from that which is specifically covered by the present invention.
D'autre part, l'enveloppe extérieure du casque décrit dans le document WO - 03/005844 comprend deux parties solidaires l'une de l'autre par l'intermédiaire d'une portion élastiquement déformable de raccordement. En outre, cette enveloppe extérieure est rendue solidaire de la coque rigide du casque par l'intermédiaire de moyens de rupture. Il est donc difficile de déterminer et de mettre en œuvre la force de résistance à la rupture qu'il convient de retenir pour un bon fonctionnement des moyens de rupture en cas de choc supporté par le casque, de sorte que, dans ce cas, le déplacement de l'enveloppe extérieure est mal assurée. D'autre part, la solution proposée par le document WO - 03/005844 n'est pratiquement pas applicable au casque du type « jet » en raison du fait qu'il est difficile de positionner précisément une enveloppe formée d'une seule pièce sur la coque rigide d'un casque de ce type, afin que l'enveloppe épouse parfaitement la totalité de la surface externe de ladite coque.On the other hand, the outer casing of the helmet described in WO-03/005844 comprises two parts secured to one another by means of an elastically deformable connection portion. In addition, this outer casing is made integral with the rigid shell of the helmet via means of rupture. It is therefore difficult to determine and implement the breaking strength that should be retained for proper operation of the breaking means in case of shock supported by the helmet, so that, in this case, the displacement of the outer shell is poorly ensured. On the other hand, the solution proposed by the document WO-03/005844 is practically not applicable to the "jet" type helmet because of the fact that it is difficult to precisely position an envelope formed of a single piece on the rigid shell of a helmet of this type, so that the envelope perfectly fits the entire outer surface of said shell.
Un but de la présente invention est de mettre à la disposition des utilisateurs, un dispositif simple, peu onéreux, facilement et rapidement interchangeable, de décoration de casque, permettant d'atténuer les effets traumatisants des chocs rotationnels.An object of the present invention is to provide users with a simple device, inexpensive, easily and quickly interchangeable helmet decoration, to mitigate the traumatic effects of rotational shocks.
Selon l'invention, ce but est atteint grâce à une enveloppe interchangeable pour casques du genre comportant une coque rigide externe, comprenant une zone destinée au recouvrement de la boite crânienne et une zone destinée au recouvrement de la nuque, ladite enveloppe étant réalisée en deux éléments flexibles distincts et indépendants l'un de l'autre, soit :According to the invention, this object is achieved by means of an interchangeable casing for helmets of the type comprising an external rigid shell, comprising a zone intended for covering the cranial box and a zone intended for covering the nape, said casing being made in two. flexible elements that are distinct and independent of one another, namely:
- un premier élément supérieur conformé pour recouvrir la zone crânienne de la coque rigide dudit casque, et,a first upper element shaped to cover the cranial zone of the rigid shell of said helmet, and
- un deuxième élément inférieur conformé pour le recouvrement de la zone de protection de la nuque,a second lower element shaped for covering the protection zone of the neck,
la bordure antérieure de l'élément supérieur et la bordure inférieure de l'élément inférieur étant aptes à coopérer avec un moyen de retenue équipant, respectivement, la bordure antérieure et la bordure inférieure dudit casque, de sorte à permettre une liaison séparable de l'enveloppe, et du casque.the anterior border of the upper element and the lower edge of the lower element being adapted to cooperate with a retaining means equipping, respectively, the front edge and the bottom edge of said helmet, so as to allow a separable connection of the envelope, and helmet.
Selon un mode de mise en œuvre avantageux, l'une des portions voisines des bordures des deux éléments comporte un enfoncement ou décrochement en retrait dans lequel se trouve logée la bordure de l'autre élément, respectivement, dans la position de montage de l'enveloppe sur un casque.According to an advantageous embodiment, one of the adjacent portions of the borders of the two elements comprises a recess or recess in withdrawal in which is located the edge of the other element, respectively, in the mounting position of the envelope on a helmet.
Suivant un mode de réalisation préféré, la bordure inférieure de l'élément supérieur comporte un décrochement ou enfoncement dans lequel se trouve logée la bordure supérieure de l'élément inférieur dans la position de montage de l'enveloppe sur un casque.According to a preferred embodiment, the lower edge of the upper element comprises a recess or recess in which is housed the upper edge of the lower element in the mounting position of the envelope on a helmet.
Selon une autre disposition caractéristique, le décrochement délimite un épaulement constituant une butée assurant une meilleure étanchéité au niveau du raccordement des deux éléments.According to another characteristic arrangement, the recess defines a shoulder constituting a stop ensuring a better seal at the connection of the two elements.
Selon un mode d'exécution avantageux, l'enveloppe interchangeable est réalisée en matière plastique flexible, par exemple en polycarbonate thermoformé.According to an advantageous embodiment, the interchangeable envelope is made of flexible plastic material, for example thermoformed polycarbonate.
Le casque est remarquable en ce qu'il est muni d'une enveloppe interchangeable comportant une ou plusieurs des caractéristiques ci-dessus.The helmet is remarkable in that it is provided with an interchangeable envelope having one or more of the above features.
Suivant une disposition caractéristique, le moyen de retenue équipant la bordure antérieure et la bordure inférieure du casque, est constitué par une lèvre extérieure élastique délimitant, avec ladite bordure du casque, une fente périphérique dans laquelle est engagée et pincée une portion de bordure des éléments de l'enveloppe interchangeable ; l'élément supérieur de l'enveloppe pouvant glisser sur la coque rigide du casque et être éjecté en cas de choc, en atténuant ainsi les effets mécaniques traumatisants de l'impact.According to a characteristic arrangement, the retaining means equipping the front edge and the lower edge of the helmet, is constituted by an elastic outer lip delimiting, with said edge of the helmet, a peripheral slot in which is engaged and pinched a portion of the edge elements the interchangeable envelope; the upper element of the envelope being able to slide on the rigid shell of the helmet and to be ejected in the event of shock, thus attenuating the traumatic mechanical effects of the impact.
Selon une autre disposition caractéristique, la bordure antérieure de l'élément supérieur est engagée dans une portion antérieure de la fente, tandis que la bordure inférieure de l'élément inférieur est engagée dans une portion inférieure de ladite fente.According to another characteristic arrangement, the front edge of the upper member is engaged in an anterior portion of the slot, while the lower edge of the lower member is engaged in a lower portion of said slot.
Suivant un mode de réalisation avantageux, l'élément inférieur de l'enveloppe est fixé sur le casque au moyen d'attaches rapides, par exemple du genre boutons pression, dont l'une des parties constitutives est fixée à chaque extrémité de l'élément inférieur de ladite enveloppe, tandis que chacune des autres parties constitutives des attaches rapides est fixée, symétriquement dans une zone antérieure et inférieure du casque, correspondant sensiblement à une zone latérale du maxillaire inférieur.According to an advantageous embodiment, the lower element of the envelope is fixed on the helmet by means of quick fasteners, for example of the snap fasteners, one of the constituent parts of which is fixed to each end of the lower element of said envelope, while each of the other constituent parts of the quick couplers is fixed, symmetrically in an anterior and inferior area of the helmet, substantially corresponding to a lateral zone of the lower jaw.
Le dispositif selon l'invention procure plusieurs avantages intéressants.The device according to the invention provides several interesting advantages.
Notamment :Especially :
- la possibilité, pour l'enveloppe, d'épouser étroitement et parfaitement la surface externe de la coque rigide du casque, malgré l'étendue et la conformation de cette surface. - de nécessiter la prévision d'aucun trou dans la partie de la coque du casque, destinée à recouvrir la boîte crânienne, pour la fixation de l'élément supérieur de l'enveloppe, ce qui préserve l'intégrité de celle-ci ;- the possibility, for the envelope, to marry closely and perfectly the outer surface of the hard shell of the helmet, despite the extent and conformation of this surface. - To require the provision of no hole in the part of the shell of the helmet, intended to cover the skull, for fixing the upper element of the envelope, which preserves the integrity thereof;
- de rendre possibles une mise en place et un retrait, en vue de son remplacement simple, facile et rapide, de l'enveloppe interchangeable permettant de modifier ainsi l'aspect extérieur du casque, ce retrait pouvant aussi intervenir à l'occasion d'un choc et assurant de la sorte une atténuation des effets traumatisants lors d'un choc rotationnel,to make it possible to set up and withdraw, with a view to its simple, easy and rapid replacement, of the interchangeable envelope making it possible to modify the external appearance of the helmet, this withdrawal also being able to intervene on the occasion of a shock and thus ensuring an attenuation of the traumatic effects during a rotational shock,
- de permettre aux particuliers de faire eux mêmes le changement de l'aspect extérieur du casque, sans faire appel à un professionnel, à partir d'un jeu d'enveloppes,- allow individuals to make their own change in the appearance of the helmet, without calling a professional, from a set of envelopes,
- de permettre la réalisation d'une seule taille de la coque du casque et de l'enveloppe amovible, l'adaptation du casque à la tête de l'utilisateur étant obtenue par la variation de l'épaisseur du polystyrène intérieur dudit casque.to allow the realization of a single size of the helmet shell and the removable envelope, the adaptation of the helmet to the user's head being obtained by varying the thickness of the inner polystyrene of said helmet.
Un avantage particulièrement intéressant de l'enveloppe interchangeable selon l'invention, et des casques munis de cette enveloppe, est qu'ils constituent un moyen efficace permettant d'atténuer les effets traumatisants du choc rotationnel en cas de chute.A particularly advantageous advantage of the interchangeable envelope according to the invention, and helmets provided with this envelope, is that they are an effective means for mitigating the traumatic effects of rotational impact in case of a fall.
On a constaté, en effet, que lorsque la tête heurte le sol, par suite d'une chute, l'impact provoque un pivotement de celle-ci et du cerveau qui suit le mouvement rotatoire du crâne avec un léger temps de retard. La violence de ce mouvement rotatoire du cerveau, à l'intérieur de la boîte crânienne, peut entraîner des traumatismes graves, souvent inopérables. Ce phénomène est connu sous le nom de « chocs rotationnels ».It has been found that when the head hits the ground as a result of a fall, the impact causes a pivoting of the latter and of the brain following the fall. Rotatory movement of the skull with a slight delay. The violence of this rotational movement of the brain, inside the cranial box, can lead to serious trauma, often inoperable. This phenomenon is known as "rotational shocks".
Grâce à l'enveloppe et au casque selon l'invention, ladite enveloppe glisse sur la coque du casque en cas de choc et se trouve éjectée, en diminuant ainsi les effets mécaniques traumatisants de l'impact. Le glissement de l'enveloppe sur la coque rigide du casque et son éjection, notamment de la partie supérieure de ladite enveloppe, se trouvent assurés en cas de choc appliqué sur l'enveloppe, sans qu'il soit nécessaire de vaincre une force de rupture s'opposant à l'effacement de ladite enveloppe.Thanks to the envelope and the helmet according to the invention, said envelope slides on the shell of the helmet in case of shock and is ejected, thereby reducing the mechanical effects traumatic impact.
