Description

DISPOSITIF D'ASSUJETTISSEMENT D'UN CASQUE SUR LA TÊTE D'UN UTILISATEUR, NOTAMMENT D'UN CYCLISTE DEVICE FOR SECURING A HELMET ON THE HEAD OF A USER, PARTICULARLY A CYCLIST
La présente invention concerne un dispositif d'assujettissement d'un casque sur la tête d'un utilisateur, notamment d'un cycliste, sans recours à des sangles de fixation.The present invention relates to a device for securing a helmet to the head of a user, in particular a cyclist, without the use of fastening straps.
On connaît des casques de cycliste destinés à protéger la tête de son porteur en cas de chocs qui répondent à des impératifs tels que légèreté et sécurité.Cyclist helmets are known which are intended to protect the head of the wearer in the event of shocks which meet imperatives such as lightness and safety.
En ce qui concerne la légèreté, les casques sont généralement fabriqués à partir d'une coque en matériau très léger, de type polystyrène expansé, sur laquelle est surmoulée une enveloppe mince généralement en polycarbonate. La légèreté évite à l'utilisateur de faire des efforts de maintien de tête trop importants lorsqu'il en est équipé, notamment durant des parcours longs ou très accidentés susceptibles d'induire des fatigues des muscles notamment du cou.With regard to lightness, helmets are generally made from a shell made of very light material, of the expanded polystyrene type, onto which a thin envelope generally made of polycarbonate is overmolded. The lightness prevents the user from making too much head support efforts when fitted, especially during long or very uneven journeys liable to induce fatigue in the muscles, particularly the neck.
En ce qui concerne la sécurité, il convient que de tels casques soient parfaitement ajustés sur la tête du porteur . Le bon ajustement permet au casque d'être bien placé par rapport aux parties qu'il doit protéger en cas de chocs. On note également un effet induit sur le confort de l'utilisateur puisque un casque bien ajusté ne risque pas de venir occulter la vision de l'utilisateur en basculant vers l'avant ou de frotter sur le cou par basculement arrière. Ces basculements ou pivotements, y compris latéraux, sont préjudiciables à la sécurité de l'utilisateur car, non seulement les zones sensibles du crâne peuvent ne plus être protégées par le casque en cas de chute, mais bien souvent l'utilisateur est tenté de repositionner son casque correctement tout en roulant ce qui peut être la cause de chutes.As far as safety is concerned, such helmets should fit perfectly on the wearer's head. The correct fit allows the helmet to be well positioned in relation to the parts it must protect in the event of impact. There is also an induced effect on the comfort of the user since a well-fitting helmet does not risk obscuring the vision of the user by tilting forward or rubbing on the neck by tilting back. These tilting or pivoting, including lateral, are detrimental to the safety of the user because, not only the sensitive areas of the skull can no longer be protected by the helmet in the event of a fall, but very often the user is tempted to reposition his helmet correctly while riding which can cause falls.
On connaît de nombreux dispositifs permettant de maintenir un casque sur le crâne d'un utilisateur, dans des conditions suffisamment satisfaisantes de sécurité. Mais ces dispositifs restent néanmoins complexes et présentent des inconvénients. C'est ainsi que le brevet US A 5 572 749 décrit des moyens de fixation d'une coque sur le crâne d'un l'utilisateur qui consiste à prévoir une ceinture périphérique réglable en diamètre, une ceinture sommitale destinée à soutenir cette ceinture périphérique sur le haut du crâne et un appui occipital prévu pour immobiliser le casque sur le crâne de l'utilisateur. Un tel dispositif présente l'avantage d'éviter toute sangle de type jugulaire. Par contre, l'agencement est complexe et ne répond aucunement au critère de légèreté recherchée notamment par les cyclistes.Numerous devices are known which make it possible to maintain a helmet on the skull of a user, under sufficiently satisfactory safety conditions. However, these devices nevertheless remain complex and have drawbacks. Thus, US Pat. No. 5,572,749 describes means for fixing a shell to the skull of a user, which consists in providing a peripheral belt adjustable in diameter, a summit belt intended to support this peripheral belt. on the top of the head and an occipital support provided to immobilize the helmet on the user's head. Such a device has the advantage of avoiding any strap of the jugular type. On the other hand, the layout is complex and in no way meets the criteria of lightness sought in particular by cyclists.
En effet, la ceinture périphérique paraît difficilement adaptable à différents types d'individus et néanmoins provoque une gêne certaine par cet effet de ceinture autour du crâne et on imagine difficilement une bonne aération de cette partie du crâne notamment dans le cas d'un effort.Indeed, the peripheral belt seems difficult to adapt to different types of individuals and nevertheless causes discomfort by this belt effect around the skull and it is difficult to imagine good ventilation of this part of the skull especially in the case of an effort.
Enfin, on note aussi que les moyens de réglage de la tension du câble de liaison s'effectue par rotation et enroulement, ce qui paraît difficile dans le cas notamment d'une application au cyclisme. On connaît aussi par le brevet US-A-3 028 602 un casque de type intégral, comportant un patin occipital et un masque facial disposés dans des plans sensiblement parallèles. Un câble circule à travers des gaines solidaires respectivement du patin occipital et du masque facial avec des moyens de tension de ces câbles permettant de rapprocher l'appui occipital du masque facial.Finally, it is also noted that the means for adjusting the tension of the connecting cable is effected by rotation and winding, which seems difficult in the case in particular of an application to cycling. Also known from US-A-3,028,602 is an integral type helmet, comprising an occipital pad and a facial mask arranged in substantially parallel planes. A cable circulates through sheaths secured respectively to the occipital pad and the facial mask with means of tensioning these cables allowing the occipital support to be brought closer to the facial mask.
Le patin d'appui occipital est immobilisé en déplacement et solidaire de l'arrière du casque intégral tandis que le masque facial est fixé uniquement en partie supérieure, ce qui lui laisse un certaine liberté de pivotement au droit du menton, de l'avant vers l'arrière et inversement.The occipital support pad is immobilized in movement and secured to the rear of the integral helmet while the facial mask is fixed only in upper part, which gives him a certain freedom of pivoting to the right of the chin, from the front to the back and vice versa.
Ainsi, l'utilisateur, les câbles étant détendus, peut enfiler le casque intégral car le masque facial est pivoté vers l'avant ce qui libère un espace suffisant pour le passage du crâne et du nez de l'utilisateur. Ensuite, l'utilisateur assure un raccourcissement du câble par des moyens adéquats en l'occurrence un enrouleur, accessible et manoeuvrable par l'extérieur du casque. Cet enroulement du câble a pour effet de prendre en étau la tête de l'utilisateur entre l'appui occipitale et le masque facial. Un tel agencement ne peut être transposé à un casque notamment pour le cyclisme car d'une part le masque facial et l'appui occipital qui englobe une grande partie arrière du crâne seraient d'un inconfort incompatible avec la pratique sportive. De plus, un masque facial pivotant pour un casque qui n'est pas intégral ne peut être envisagé, ne serait-ce qu'esthétiquement. Enfin d'un point de vue pratique, le maintien du menton de l'utilisateur est rédhibitoire.Thus, the user, the cables being relaxed, can put on the full-face helmet because the facial mask is pivoted forward which frees up sufficient space for the passage of the user's skull and nose. Then, the user ensures a shortening of the cable by suitable means, in this case a reel, accessible and maneuverable from outside the helmet. This winding of the cable has the effect of gripping the user's head between the occipital support and the facial mask. Such an arrangement cannot be transposed to a helmet, in particular for cycling, because on the one hand the facial mask and the occipital support which encompasses a large rear part of the skull would be of discomfort incompatible with sports practice. In addition, a pivoting facial mask for a helmet that is not integral cannot be envisaged, if only aesthetically. Finally from a practical point of view, maintaining the user's chin is unacceptable.
On a également connaissance d'un modèle d'utilité allemand DE-U-296 1 3 682 qui décrit un perfectionnement pour le maintien d'un casque de conception simple disposant d'une simple sangle périphérique. La sangle ainsi décrite passe sur le front de l'utilisateur et sous l'occiput du crâne du porteur, l'invention consistant à prévoir des moyens d'ajustement de la longueur de cette sangle. De tels moyens comprennent un système d'enroulement de câbles et de glissières interposé entre les extrémités de cette sangle monolithique.We are also aware of a German utility model DE-U-296 1 3 682 which describes an improvement for the maintenance of a helmet of simple design having a simple peripheral strap. The strap thus described passes over the forehead of the user and under the occiput of the wearer's skull, the invention consisting in providing means for adjusting the length of this strap. Such means include a cable winding system and slides interposed between the ends of this monolithic strap.
Un tel agencement présente toujours l'inconvénient de faire le tour du crâne de l'utilisateur et de provoquer une gêne certaine. On note de plus que l'utilisateur doit défaire complètement le réglage à chaque mise en place du casque. Il n'est pas possible de prévoir un préréglage.Such an arrangement always has the drawback of going around the user's skull and causing certain discomfort. It is further noted that the user must completely undo the adjustment each time the helmet is fitted. It is not possible to provide a preset.
Aussi, la présente invention a pour but de pallier les inconvénients précités des dispositifs connus de l'art antérieur et propose un dispositif d'assujettissement sous-mastoïdien/frontal d'un casque sur le crâne d'un utilisateur notamment d'un cycliste qui supprime tout basculement avant/arrière/latéral qui est simple, léger, qui conserve les avantages des dispositifs existants, à savoir l'interdiction d'arrachement du casque qui génère un grand confort par un forte limitation des surfaces d'appui, qui est doté d'un préréglage très précis et de moyens de fermeture tout ou rien et qui peut être adapté à toute forme de coque. A cet effet, le dispositif d'assujettissement d'un casque selon l'invention, sur la tête d'un utilisateur, ce casque comprenant une coque avec une enveloppe se caractérise en ce qu'il comprend un appui frontal, un appui sous-mastoïdien, double, ainsi que des moyens de rapprochement de l'appui sous-mastoïdien, double de cet appui frontal. Plus précisément, l'appui frontal est solidaire de la coque du casque et l'appui sous-mastoïdien double est articulé par rapport à la coque, en sorte de réaliser une triangulation dans un plan oblique P.Also, the present invention aims to overcome the aforementioned drawbacks of the known devices of the prior art and proposes a device for sub-mastoid / frontal securing of a helmet on the skull of a user, in particular of a cyclist who eliminates any tilting forward / backward / lateral which is simple, light, which retains the advantages of existing devices, namely the ban on removing the helmet which generates great comfort by greatly limiting the bearing surfaces, which has a very precise preset and all or nothing closure means and which can be adapted to any form of hull. To this end, the device for securing a helmet according to the invention, on the head of a user, this helmet comprising a shell with an envelope is characterized in that it comprises a front support, a sub-support mastoid, double, as well as means for bringing the sub-mastoid support, double this frontal support. More specifically, the front support is integral with the helmet shell and the double sub-mastoid support is articulated relative to the shell, so as to produce a triangulation in an oblique plane P.
Selon un mode préférentiel de réalisation, l'appui sous-mastoïdien, double, est en forme de T renversé, la branche principale étant fixée de façon articulée par rapport à la coque pour prendre deux positions, la première ouverte dans laquelle les branches sont éloignées de la zone mastoïdienne et la seconde fermée dans laquelle les extrémités des branches viennent en appui sur ladite zone D mastoïdienne.According to a preferred embodiment, the sub-mastoid support, double, is in the shape of an inverted T, the main branch being fixed in an articulated manner relative to the shell to take two positions, the first open in which the branches are distant of the mastoid area and the second closed in which the ends of the branches come to bear on said mastoid area D.
Selon un perfectionnement, la branche principale comprend une zone élastique susceptible de se déformer.According to an improvement, the main branch comprises an elastic zone capable of deforming.
Selon le même mode de réalisation préférentiel, les moyens de rapprochement de l'appui frontal avec l'appui sous-mastoïdien double comprennent deux câbles latéraux de traction, l'une des extrémités libres est fixée sur l'extrémité correspondante de la branche latérale correspondante de l'appui sous-mastoïdien et l'autre des extrémités libres est liée à des moyens de traction.According to the same preferred embodiment, the means for bringing the front support closer to the double sub-mastoid support include two lateral traction cables, one of the free ends is fixed to the corresponding end of the corresponding side branch of the sub-mastoid support and the other of the free ends is linked to traction means.
Ces moyens de traction comprennent un câble de traction, dont l'extrémité est solidaire d'un levier d'une platine, ce levier étant susceptible de prendre deux positions, une première position, dite ouverte, dans laquelle le câble de traction est relâché, et une seconde position, dite fermée, par effet de genouillère, dans laquelle le câble est tendu. Les moyens de traction comprennent des moyens de réglage fin de la tension.These traction means comprise a traction cable, the end of which is secured to a lever of a plate, this lever being capable of assuming two positions, a first position, called open, in which the traction cable is released, and a second position, called closed, by toggle effect, in which the cable is stretched. The traction means comprise means for fine adjustment of the tension.
Selon un agencement particulier, chaque câble coulisse dans une gaine formant une boucle en Ç, ouverte vers l'arrière du casque, cette gaine étant de préférence noyée et maintenue dans l'épaisseur de la coque du casque.According to a particular arrangement, each cable slides in a sheath forming a loop in Ç, open towards the rear of the helmet, this sheath preferably being embedded and held in the thickness of the shell of the helmet.
Il est aussi prévu un support pivotant, ménagé à proximité de chaque câble pour assurer un meilleur guidage.A pivoting support is also provided, arranged near each cable to ensure better guidance.
L'appui frontal comprend également une zone élastique susceptible de se déformer La présente invention est maintenant décrite selon un mode de réalisation particulier non limitatif, en regard des dessins annexés sur lesquels les différentes figures représentent :The front support also includes an elastic zone liable to deform. The present invention is now described according to a particular non-limiting embodiment, with reference to the appended drawings in which the different figures represent:
- Figure 1 , une vue en élévation latérale d'un casque avec coupe uniquement de la coque du casque, en position d'introduction ; - Figure 2, une vue identique à celle de la figure 1 , mais en position de fermeture ;- Figure 1, a side elevational view of a helmet with section only of the helmet shell, in the insertion position; - Figure 2, a view identical to that of Figure 1, but in the closed position;
- Figure 3, une vue identique à celle de la figure 2 sur laquelle on a symbolisé les différentes directions des efforts exercés ; et- Figure 3, a view identical to that of Figure 2 in which we symbolized the different directions of the forces exerted; and
- Figure 4, une vue de dessous du dispositif selon l'invention. Sur la figure 1 , on a représenté la tête 1 0 d'un utilisateur dont le crâne 1 2 supporte un casque 1 4 comprenant une coque 1 6 et des moyens d'assujettissement 1 8 de cette coque sur le crâne 1 2 de l'utilisateur.- Figure 4, a bottom view of the device according to the invention. In Figure 1, there is shown the head 1 0 of a user whose skull 1 2 supports a helmet 1 4 comprising a shell 1 6 and securing means 1 8 of this shell on the skull 1 2 of the user.
Dans l'exemple représenté, le casque est de type profilé et on peut distinguer des zones respectivement frontale A, sommitale B et occipitale C. Le casque comprend la coque 1 6 proprement dite qui est réalisée en un matériau amortissant les chocs, de type polystyrène expansé, sur laquelle est surmoulée une enveloppe 17.In the example shown, the helmet is of the profiled type and we can distinguish respectively frontal A, summit B and occipital C. The helmet comprises the shell 1 6 itself which is made of a shock absorbing material, of polystyrene type expanded, on which an envelope 17 is overmolded.
Dans la zone occipitale C, on distinguera une zone particulière D dite sous-mastoïdienne. Cette zone, comme montré sur la figure 1 , est située immédiatement en dessus du cou et au droit de la partie inférieure de l'oreille, en arrière de la mâchoire, et sous la zone occipitale proprement dite. Les moyens 1 8 d'assujettissement comprennent un appui 20 frontal, un appui sous-mastoïdien 22, double, ainsi que des moyens 24 de rapprochement de cet appui 20 frontal avec l'appui 22 sous-mastoïdien, double.In the occipital zone C, a particular zone D, called the sub-mastoid, can be distinguished. This area, as shown in Figure 1, is located immediately above the neck and in line with the lower part of the ear, behind the jaw, and under the occipital area proper. The means 1 8 for securing comprise a front support 20, a sub-mastoid support 22, double, as well as means 24 for bringing this front support 20 closer to the support 22 sub-mastoid, double.
L'appui 20 frontal est fixé latéralement à la coque 1 6 en deux points 26 et il est supporté par une languette 28 souple médiane dont l'extrémité 30 libre est solidaire de la partie sommitale B de la coque. L'appui 20 frontal est ainsi fixé en trois points sur la coque 1 6.The front support 20 is fixed laterally to the shell 1 6 at two points 26 and it is supported by a flexible central tongue 28 whose free end 30 is secured to the top part B of the shell. The front support 20 is thus fixed at three points on the shell 1 6.
Selon un perfectionnement du mode de réalisation préféré de l'invention qui est représenté sur la figure 1 , la languette 28 souple comprend une zone 32 déformable élastiquement. Cette zone comprend un pliage en S lorsque la languette est en matériau plastique et venue de moulage, comme dans le mode de réalisation représenté.According to an improvement of the preferred embodiment of the invention which is shown in Figure 1, the flexible tongue 28 comprises an elastically deformable zone 32. This zone includes an S-fold when the tongue is made of plastic material and molded, as in the embodiment shown.
L'appui 22 sous-mastoïdien, double, a une forme sensiblement de T renversé, la branche 34 principale étant fixée sur la coque, sensiblement dans la partie sommitale B tandis que les deux branches 36 latérales du T sont conformées anatomiquement pour que leurs extrémités viennent en appui dans la zone sous-mastoïdienne D. De façon analogue à l'appui frontal, cet appui comprend un zone 38 déformable élastiquement.The double sub-mastoid support 22 has a substantially inverted T shape, the main branch 34 being fixed to the shell, substantially in the top part B while the two lateral branches 36 of the T are anatomically shaped so that their ends come to rest in the submastoid zone D. In a similar manner to the frontal support, this support comprises an elastically deformable zone 38.
Les moyens 24 de rapprochement de l'appui frontal et de l'appui sous- mastoïdien comprennent, dans le mode de réalisation représenté sur la figure 1 , notamment deux câbles 40 latéraux. Pour chaque câble, l'une des extrémités libres 42 est fixée sur l'extrémité correspondante de la branche 36 latérale correspondante de l'appui 22 sous-mastoïdien. Chaque câble 40 coulisse dans une gaine 44 formant une boucle en C ouverte vers l'arrière du casque, cette gaine étant de préférence noyée et maintenue dans l'épaisseur de la coque du casque. Un support 46 pivotant est également ménagé à proximité du câble pour assurer un meilleur guidage comme cela sera expliqué ultérieurement.The means 24 for bringing the front support and the sub-mastoid support together, in the embodiment shown in FIG. 1, include two side cables 40. For each cable, one of the free ends 42 is fixed to the corresponding end of the corresponding lateral branch 36 of the sub-mastoid support 22. Each cable 40 slides in a sheath 44 forming a C-shaped loop open towards the rear of the helmet, this sheath preferably being embedded and held in the thickness of the shell of the helmet. A pivoting support 46 is also provided near the cable to ensure better guidance as will be explained later.
Chacun des deux câbles 40 a son autre extrémité 48 libre fixée sur une platine 50 de liaison, elle-même solidaire de l'extrémité 52, d'un câble unique 54. L'une 56 des extrémités de ce câble 40 est solidaire de moyens 58 de traction équipés de moyens 60 de réglage fin. Ces moyens 58 de traction comprennent une platine 62 et un levier 64 susceptible de prendre deux positions, une première position, dite ouverte dans laquelle le câble 54 est relâché, et une seconde position, dite fermée, par effet de genouillère, comme montré sur les figures 2 et 3, dans laquelle le câble 54 est tendu.Each of the two cables 40 has its other free end 48 fixed on a connection plate 50, itself secured to the end 52, of a single cable 54. One 56 of the ends of this cable 40 is secured to means 58 of traction fitted with means 60 for fine adjustment. These traction means 58 comprise a plate 62 and a lever 64 capable of assuming two positions, a first position, called open in which the cable 54 is released, and a second position, called closed, by toggle effect, as shown on the Figures 2 and 3, in which the cable 54 is stretched.
On note que ces moyens 58 de traction sont disposés dans la zone occipitale C du casque rendant le levier 64 aisément accessible à l'utilisateur, par le dessous de la coque.Note that these traction means 58 are arranged in the occipital zone C of the helmet making the lever 64 easily accessible to the user, from below the shell.
Sur la figure 3, on a représenté par différente flèches, les directions des efforts exercés lors de la manoeuvre du levier 64 de la première position ouverte vers la seconde position fermée. La traction du levier 64 provoque la tension du câble 54 et des câbles 40 latéraux qui en sont solidaires, suivant la flèche F1 . Par la boucle en C ménagée avec les gaines 44, les câbles 40 assurent la traction de l'appui 22 sous-mastoïdien vers l'avant suivant la flèche F2.In Figure 3, there are shown by different arrows, the directions of the forces exerted during the operation of the lever 64 from the first open position to the second closed position. The pulling of the lever 64 causes the tension of the cable 54 and of the side cables 40 which are integral therewith, according to arrow F1. By the C loop formed with the sheaths 44, the cables 40 ensure the traction of the sub-mastoid support 22 forwards along the arrow F2.
Ces efforts exercés se traduisent par une pression de l'appui sous- mastoïdien suivant la flèche G1 et par une réaction sur l'appui 20 frontal fixé au casque suivant la flèche G2. Il y donc essentiellement trois points d'immobilisation du casque sur la tête de l'utilisateur à savoir un point d'appui frontal et deux points d'appui sous-mastoïdien. Le triangle ainsi formé dans le plan oblique P dans lequel s'exercent les efforts résultants symbolisés par les flèches G1 et G2 permet d'éviter d'une part l'arrachement du casque et d'autre part le basculement avant arrière et même latéral.These forces exerted result in a pressure of the submastoid support in the direction of arrow G1 and in a reaction on the front support 20 fixed to the helmet in the direction of arrow G2. There are therefore essentially three points of immobilization of the helmet on the head of the user, namely a front support point and two sub-mastoid support points. The triangle thus formed in the oblique plane P in which the resulting forces are exerted symbolized by the arrows G1 and G2 makes it possible on the one hand to avoid the tearing of the helmet and on the other hand the tilting before rear and even lateral.
On note que dans le cas d'une traction, les zones 32 et 38 élastiques déformables assurent le rôle d'amortisseur, sans pour autant modifier les capacités de retenue du casque sur la tête, comme cela est montré sur la figure 3.It is noted that in the case of traction, the deformable elastic zones 32 and 38 perform the role of shock absorber, without however modifying the capacities for retaining the helmet on the head, as shown in FIG. 3.
L'enfoncement du casque est évidemment limité par appui de la coque sur la zone sommitale B, ceci de façon connue. Les moyens 60 de réglage fin de la tension du câble permettent d'obtenir l'effet de blocage par genouillère en fonction de la taille et de la morphologie de l'utilisateur. De plus, les moyens à levier avec genouillère permettent de disposer d'un préréglage par manoeuvre des moyens 60 de réglage fin, avec une mise en place aisée du casque car une fois ce préréglage effectué et le casque mis en place, il suffit de basculer le levier, en une seule manoeuvre, pour obtenir un assujettissement parfaitement adapté.The insertion of the helmet is obviously limited by pressing the shell on the summit zone B, this in a known manner. The means 60 for fine adjustment of the cable tension make it possible to obtain the locking effect by toggle joint as a function of the size and morphology of the user. In addition, the lever means with a toggle joint make it possible to have a presetting by maneuvering means 60 for fine adjustment, with easy fitting of the helmet because once this presetting has been carried out and the helmet in place, it suffices to switch the lever, in a single maneuver, to obtain a perfectly adapted securing.
On note également l'absence d'une ceinture périphérique autour de la tête de l'utilisateur ainsi que l'absence de tout élément sur le visage de ce même utilisateur.We also note the absence of a peripheral belt around the head of the user as well as the absence of any element on the face of the same user.
Sur la figure 4, on constate mieux encore la simplicité du dispositif d'assujettissement selon l'invention. In FIG. 4, the simplicity of the securing device according to the invention can be seen more clearly.
