Description

L'invention concerne un casque de protection pour activité sportive. De telles activités peuvent être notamment du cyclisme au sens large, que ce soit sur route ou tout terrain. L'invention s'étend également au casque conçu pour la pratique de l'escalade, de la spéléologie, de l'alpinisme, du ski alpin, du ski de randonnée, du surf des neiges. Généralement, un casque forme une protection de la tête, pour protéger le crâne des chocs qu'il pourrait subir lorsque l'utilisateur fait une chute ou lorsqu'un objet est projeté dans sa direction.The invention relates to a protective helmet for sports activity. Such activities may include cycling in the broad sense, whether on the road or in the field. The invention also extends to the helmet designed for the practice of climbing, caving, mountaineering, downhill skiing, ski touring, snowboarding. Generally, a helmet forms a protection of the head, to protect the skull of the shocks that it could undergo when the user makes a fall or when an object is projected in its direction.

Un tel casque comprend généralement une coiffe et une sangle jugulaire.Such a helmet generally includes a cap and a jugular strap.

La coiffe est destinée à recouvrir le crâne de l'utilisateur. C'est la coiffe qui confère la protection de la tête. Le plus souvent, elle est composée d'une coque externe et d'une calotte interne. La coque externe est généralement rigide, et est composée d'une matière thermoplastique telle que l'ABS (Acrylonitrile Butadiène Styrène) ou le PC (PolyCarbonate). De manière courante, la calotte interne est réalisée dans un matériau expansé tel que l'EPS (Expandable PolyStyrene) ou l'EPP (Expandable PolyPropylene).The cap is intended to cover the skull of the user. This is the headdress that gives the protection of the head. Most often, it is composed of an outer shell and an inner cap. The outer shell is generally rigid, and is made of a thermoplastic material such as ABS (Acrylonitrile Butadiene Styrene) or PC (PolyCarbonate). Commonly, the inner cap is made of an expanded material such as EPS (Expandable PolyStyrene) or EPP (Expandable PolyPropylene).

La sangle jugulaire est solidaire de la coiffe. Elle est généralement reliée à la coiffe à trois niveaux : sur une partie antérieure latérale gauche, sur une partie antérieure latérale droite et sur une partie postérieure centrale (au niveau de l'occiput). Cette construction permet de générer deux boucles latérales. Une première boucle est formée entre la partie antérieure latérale gauche et la partie postérieure centrale de la coiffe. Une deuxième boucle est formée entre la partie antérieure latérale droite et la partie postérieure centrale de la coiffe. Chaque boucle entoure la partie inférieure d'une oreille et se prolonge, en-dessous, par une extension portant, à son extrémité, une pièce de fixation. L'extension de chaque boucle est destinée à se caler sous le menton. La pièce de fixation d'une boucle est apte à coopérer, sous le menton ou au niveau de la joue, avec la pièce de fixation complémentaire de l'autre boucle. Grâce à cette accroche, les deux boucles sont solidaires, ce qui permet de maintenir la coiffe sur la tête. La coiffe est retenue par les sangles qui viennent s'appuyer contre le menton dès qu'on écarte la coiffe du crâne. Pour pouvoir ajuster la longueur de la sangle jugulaire afin de s'adapter à la morphologie de l'utilisateur, la sangle jugulaire comprend deux sangles distinctes. Le plus souvent, ces deux sangles sont solidarisées au niveau d'une extension, et plus particulièrement, au niveau d'une pièce de fixation. Au niveau de la pièce de fixation complémentaire, c'est une même sangle qui est reliée à cette pièce. La liaison entre la pièce de fixation complémentaire et la sangle est alors de type passant. La sangle peut ainsi coulisser librement à travers le passant. Ce même type de liaison relie la sangle jugulaire à la partie postérieure centrale de la coiffe.The jugular strap is integral with the cap. It is generally connected to the three-tiered cuff: on an anterior left lateral, on a right lateral anterior part and on a central posterior part (at the level of the occiput). This construction makes it possible to generate two lateral loops. A first loop is formed between the left lateral anterior portion and the central posterior portion of the cap. A second loop is formed between the right lateral anterior portion and the central posterior portion of the cap. Each loop surrounds the lower part of an ear and is extended, below, by an extension carrying, at its end, a fastener. The extension of each loop is intended to wedge under the chin. The fastening part of a loop is adapted to cooperate, under the chin or at the cheek, with the complementary fastener of the other loop. With this hook, the two loops are secured, which keeps the headdress on the head. The cap is held by the straps that come to rest against the chin as soon as you remove the headdress of the skull. To be able to adjust the length of the chin strap to fit the user's morphology, the chin strap has two separate straps. Most often, these two straps are secured at an extension, and more particularly, at a fastener. At the level of the complementary fastening piece, it is the same strap that is connected to this piece. The connection between the complementary fastener and the strap is then of type. The strap can slide freely through the loop. This same type of connection connects the jugular strap to the central rear part of the cap.

Il existe différents moyens de fixation de la sangle jugulaire au niveau des parties antérieures latérales. A titre d'exemples, les documents US 5,269,025 ; US 2007/044210 ; US 8,091,148 ; US 5,005,220 décrivent certaines solutions. Dans tous les cas, la sangle jugulaire est fixée à la coiffe par l'intermédiaire d'une pièce dédiée uniquement à cette fixation, tout au moins, dans la partie antérieure de la coiffe.There are different ways of attaching the jugular strap at the lateral front parts. As examples, documents US 5,269,025 ; US 2007/044210 ; US 8,091,148 ; US5,005,220 describe some solutions. In all cases, the jugular strap is fixed to the cap by means of a room dedicated solely to this attachment, at least in the front part of the cap.

En fonction de l'utilisation du casque, l'utilisateur peut être amené à fixer des accessoires sur le casque. Par exemple, il peut ajouter une visière pour protéger ses yeux du soleil et/ou de la pluie. D'autres accessoires sont envisageables. Ce peut être un écran de protection oculaire, une lampe... Ces accessoires sont généralement fixés à la coiffe par un support spécifique, différent de la pièce de fixation de la sangle jugulaire.Depending on the use of the headset, the user may be required to attach accessories on the helmet. For example, he can add a visor to protect his eyes from the sun and / or rain. Other accessories are possible. It can be an eye protection screen, a lamp ... These accessories are usually attached to the cap by a specific support, different from the fastening part of the jugular strap.

Ces constructions permettent un positionnement adapté des accessoires mais rend la conception du casque plus complexe. La coiffe intègre ainsi une multitude de logements pour les différents supports de fixation que ce soit pour la sangle jugulaire ou pour une visière. Ces logements pénalisent l'esthétique externe du casque et fragilisent la structure. Par ailleurs, avec des supports de fixations dédiés, on augmente le nombre de pièces constitutives du casque ce qui l'alourdit.These constructions allow a suitable positioning of the accessories but makes the design of the helmet more complex. The cap thus integrates a multitude of housing for the different mounting brackets whether for the jugular strap or for a visor. These housing penalize the external aesthetics of the helmet and weaken the structure. Moreover, with dedicated mounting brackets, the number of constituent parts of the helmet is increased which makes it heavier.

L'invention vise à résoudre un ou plusieurs de ces inconvénients.The invention aims to solve one or more of these disadvantages.

Un but de l'invention est notamment de proposer un casque amélioré.An object of the invention is in particular to provide an improved helmet.

Un but est notamment de proposer une structure de casque allégée.One goal is to provide a lightweight helmet structure.

Un autre but est de proposer un casque esthétique.Another goal is to propose an aesthetic helmet.

Un autre but est de proposer un casque ayant une construction simplifiée comprenant un minimum de pièces constitutives.Another object is to provide a helmet having a simplified construction comprising a minimum of component parts.

Un autre but est de proposer un casque économique.Another goal is to offer an economical helmet.

L'invention porte ainsi sur un casque pour la pratique sportive comprenant une coiffe destinée à se positionner sur un crâne, une sangle jugulaire, au moins un support destiné à être solidarisé avec la coiffe, le support comprenant un moyen d'accroche de la sangle jugulaire. Le support comprend en outre un élément de fixation d'un accessoire, l'élément de fixation étant conçu pour permettre un démontage facile de l'accessoire du support.The invention thus relates to a helmet for sporting practice comprising a cap intended to be positioned on a skull, a jugular strap, at least one support intended to be secured to the cap, the support comprising means for attaching the strap. jugular. The support further comprises an attachment element of an accessory, the fastener being designed to allow easy disassembly of the support accessory.

Ainsi, le support présente une double fonctionnalité. D'une part, il sert de point d'ancrage de la sangle jugulaire sur la coiffe et, d'autre part, il sert d'élément de fixation d'un accessoire. Cette conception permet de réduire le nombre de pièce puisqu'il n'y a plus besoin de pièce spécifique pour fixer l'accessoire. Le casque comprend donc moins de pièces constitutives et s'allège en conséquence. La coiffe n'est pas fragilisée par des logements supplémentaires. Un seul support est visible ce qui améliore le design externe. En effet, avec des constructions classiques, pour chaque partie latérale antérieure, la coiffe comprend deux inserts rapportés, un pour la sangle jugulaire et un pour l'accessoire. Celui de la sangle jugulaire est toujours apparent. Celui de l'accessoire est visible uniquement lorsque l'accessoire n'est pas monté sur le casque. Avec le mode de réalisation proposé, un seul support est apparent sur chaque partie latérale antérieure de la coiffe lorsque l'accessoire n'est pas assemblé. Ce support n'est plus visible dès que l'accessoire est monté sur le casque.Thus, the support has a dual functionality. On the one hand, it serves as anchor point of the jugular strap on the cap and, secondly, it serves as an attachment element of an accessory. This design reduces the number of pieces because there is no need for specific parts to fix the accessory. The helmet therefore comprises fewer components and lightened accordingly. The cap is not weakened by additional housing. Only one support is visible which improves the external design. Indeed, with conventional constructions, for each anterior lateral part, the cap comprises two inserts reported, one for the jugular strap and one for the accessory. That of the jugular strap is always apparent. That of the accessory is visible only when the accessory is not mounted on the helmet. With the proposed embodiment, a single support is visible on each anterior lateral portion of the cap when the accessory is not assembled. This support is no longer visible as soon as the accessory is mounted on the helmet.

Les figures 1 et 2 illustrent un casque 1 pour le cyclisme. Bien entendu, l'invention n'est pas limitée à cette activité et peut être transposée à des casques pour la pratique d'autres sports.The figures 1 and 2 illustrate a helmet 1 for cycling. Of course, the invention is not limited to this activity and can be transposed to helmets for the practice of other sports.

Dans cet exemple, le casque 1 comprend une coiffe 2 équipée de supports 3 d'une sangle jugulaire 4.In this example, the helmet 1 comprises a cap 2 equipped with supports 3 of a jugular strap 4.

La coiffe 2 peut être réalisée par un procédé dit de thermoformage ou « in-mold » permettant de solidariser par injection une coque externe 21 avec une calotte interne 22. D'autres procédés de réalisation de la coiffe peuvent être envisagés. Par exemple, la coque externe 21 peut être réalisée par moulage et assemblée postérieurement, par tout moyen approprié, à une calotte interne 22 réalisée par injection, indépendamment. Dans ces exemples, la coiffe comprend ainsi une couche dure externe, réalisée en ABS ou en PC ou par un autre polymère. Cette couche dure correspond à la coque externe. La coque externe 21 définit une surface enveloppe externe S2 orientée vers l'extérieure caractérisant le design externe du casque. Cette couche externe apporte une protection aux impacts et à la perforation. La coiffe comprend en outre une couche amortissante, réalisée avec un matériau expansé tel que l'EPS ou l'EPP. Cette couche amortissante correspond à la calotte interne. Des parties de la calotte interne peuvent être visibles de l'extérieur. La coque externe protège également la calotte interne, moins résistante aux perforations.The cap 2 can be made by a so-called thermoforming process or "in-mold" for securing by injection an outer shell 21 with an inner cap 22. Other methods of making the cap can be envisaged. For example, the outer shell 21 may be made by molding and subsequently assembled, by any appropriate means, to an inner cap 22 made by injection, independently. In these examples, the cap thus comprises an outer hard layer, made of ABS or PC or another polymer. This hard layer corresponds to the outer shell. The outer shell 21 defines an outer envelope surface S2 facing outward characterizing the external design of the helmet. This outer layer provides protection against impacts and perforation. The cap further comprises a damping layer made of an expanded material such as EPS or EPP. This damping layer corresponds to the inner cap. Parts of the inner cap may be visible from the outside. The outer shell also protects the inner cap, less resistant to punctures.

La coiffe est également munie d'ouvertures d'aération 23, traversant la coiffe, permettant de ventiler le crâne lors de la pratique du sport.The cap is also provided with ventilation openings 23, through the cap, to ventilate the skull during the practice of the sport.

La coiffe comprend aussi, dans sa partie antérieure, c'est-à-dire dans la partie avant du casque, entre la partie médiane dans le sens longitudinal et l'extrémité avant du casque, deux orifices latéraux 24 traversant la coiffe. Ces orifices latéraux 24 sont disposés symétriquement par rapport à un plan médian sagittal de la coiffe. Ces orifices latéraux sont placés dans le tiers avant de la coiffe, légèrement au-dessus des tempes.The cap also comprises, in its front part, that is to say in the front part of the helmet, between the middle part in the longitudinal direction and the front end of the helmet, two lateral orifices 24 passing through the cap. These lateral orifices 24 are arranged symmetrically with respect to a sagittal median plane of the cap. These lateral orifices are placed in the front third of the cap, slightly above the temples.

Chaque orifice latéral 24, droit et gauche, est destiné à recevoir un support 3 de la sangle jugulaire 4.Each lateral orifice 24, right and left, is intended to receive a support 3 of the jugular strap 4.

Ce support 3 permet d'une part, de solidariser la sangle jugulaire 4 avec la coiffe 2 et d'autre part, de fixer un accessoire sur le casque. L'accessoire peut être un cache 5, une visière 6, un écran optique, une lampe ou d'autres objets. La figure 1 illustre l'assemblage de deux types d'accessoire : soit un cache 5, soit une visière 6.This support 3 allows on the one hand, to secure the jugular strap 4 with the cap 2 and secondly, to fix an accessory on the helmet. The accessory may be a cover 5, a visor 6, an optical screen, a lamp or other objects. The figure 1 illustrates the assembly of two types of accessory: either a cover 5 or a visor 6.

Dans ce mode de réalisation, la sangle jugulaire 4 est assemblée à la coiffe 2 par les deux supports latéraux avant 3 et par une pièce support arrière, non représentée, placée dans la partie arrière de la coiffe, au niveau de l'occiput.In this embodiment, the jugular strap 4 is assembled to the cap 2 by the two front lateral supports 3 and by a rear support piece, not shown, placed in the rear part of the cap, at the occiput.

Les supports latéraux avant 3 sont identiques. Un tel support est illustré dans les figures 3 à 6.The front side supports 3 are identical. Such support is illustrated in Figures 3 to 6 .

Dans cet exemple, le support 3 forme une pièce allongée selon une direction longitudinale X-X, illustrée à la figure 4. On définit l'axe transversal Y-Y, la direction perpendiculaire à l'axe longitudinal X-X. Le support 3 comprend une plaque 31, de forme ovale, définie par une face supérieure 311 et une face inférieure 312. Une paroi longitudinale 32 fait saillie dans la zone centrale de la face inférieure 312 et s'étend le long de l'axe longitudinal X-X. La paroi longitudinale est centrée sur la plaque 31. Elle est dimensionnée de sorte que des zones de la face inférieure 312 ne sont pas recouvertes par la paroi longitudinale. Avantageusement, les zones non recouvertes entourent la paroi longitudinale.In this example, the support 3 forms an elongate piece in a longitudinal direction XX, illustrated in FIG. figure 4 . We define the transverse axis YY, the direction perpendicular to the longitudinal axis XX. The support 3 comprises a plate 31, oval shape, defined by an upper face 311 and a lower face 312. A longitudinal wall 32 protrudes into the central zone of the lower face 312 and extends along the longitudinal axis XX. The longitudinal wall is centered on the plate 31. It is dimensioned so that areas of the lower face 312 are not covered by the longitudinal wall. Advantageously, the uncovered areas surround the longitudinal wall.

La paroi longitudinale 32 est destinée à s'insérer dans l'orifice latéral 24. Elle est dimensionnée pour ne pas interférer avec l'orifice latéral 24 lorsque le support est assemblé à la coiffe. Par ailleurs, la plaque 31 est dimensionnée pour ne pas pouvoir passer à travers l'orifice latéral 24. Ainsi, lorsqu'on assemble le support sur la coiffe, la paroi longitudinale pénètre, depuis la surface enveloppe externe S2, à l'intérieur de l'orifice latéral mais son insertion est limitée par la plaque 31. La face inférieure 312 vient alors en appui sur la coiffe.The longitudinal wall 32 is intended to be inserted into the lateral orifice 24. It is dimensioned so as not to interfere with the lateral orifice 24 when the support is assembled to the cap. On the other hand, the plate 31 is dimensioned so as not to be able to pass through the lateral orifice 24. Thus, when the support is assembled on the cap, the longitudinal wall penetrates, from the outer envelope surface S2, into the lateral orifice but its insertion is limited by the plate 31. The lower face 312 then bears on the cap.

L'orifice latéral 24 de la coiffe comprend avantageusement un épaulement 241 de sorte que la plaque 31 soit sensiblement noyée dans la coiffe. L'intérieur de l'épaulement 241 n'est pas considéré, au sens de l'invention, comme délimitant la surface enveloppe externe S2 de la coiffe. En conséquence, la face supérieure 311 est en retrait par rapport à la surface enveloppe externe S2, lorsque le support est assemblé à la coiffe. Cela permet de ne pas perturber les propriétés aérodynamiques du casque et de ne pas abîmer le support assemblé car il est protégé par la coiffe. Selon l'exemple illustré, la coque externe 21 recouvre l'intérieur de l'épaulement 241, comme on le voit à la figure 5. Ainsi, la plaque 31 vient en appui sur la coque externe 21. Celle-ci étant rigide, cela améliore la reprise d'effort du support sur la coiffe lorsqu'on tire sur la sangle jugulaire. La position relative entre le support et la coiffe reste sensiblement la même. Le réglage longueur de la sangle n'est pas affecté. Alternativement, on peut prévoir que la coque externe 21 ne recouvre pas le fond de l'épaulement auquel cas la plaque 31 vient en appui sur la calotte interne 22.The lateral orifice 24 of the cap advantageously comprises a shoulder 241 so that the plate 31 is substantially embedded in the cap. The interior of the shoulder 241 is not considered, within the meaning of the invention, as delimiting the outer envelope surface S2 of the cap. As a result, the upper face 311 is recessed with respect to the outer envelope surface S2, when the support is assembled to the cap. This makes it possible not to disturb the aerodynamic properties of the helmet and not to damage the assembled support because it is protected by the cap. According to the illustrated example, the outer shell 21 covers the inside of the shoulder 241, as seen in FIG. figure 5 . Thus, the plate 31 bears on the outer shell 21. The latter being rigid, it improves the recovery of force of the support on the cap when pulling on the jugular strap. The relative position between the support and the cap remains substantially the same. The length adjustment of the strap is not affected. Alternatively, it can be provided that the outer shell 21 does not cover the bottom of the shoulder in which case the plate 31 bears on the inner cap 22.

Pour maintenir le support solidaire de la coiffe, la paroi longitudinale 32 peut comprendre un organe d'ancrage permettant de s'interférer avec la paroi interne 242 de l'orifice latéral 24. Dans cet exemple, l'organe d'ancrage est réalisé par deux crochets 321 faisant saillie selon la direction longitudinale X-X de la paroi longitudinale 32. Les deux crochets 321 sont disposés à proximité de la face inférieure libre 322 de la paroi longitudinale. Lors de l'insertion du support, ces deux crochets se déforment légèrement et viennent pénétrer dans la matière de la calotte interne. Cette liaison permet une bonne tenue mais n'est pas facile à démonter. On peut envisager d'autres organes d'ancrage que celui-ci. Ce peut être un clip traversant la coiffe. Ce peut être une série de dentures. L'organe d'ancrage peut permettre le démontage ou non du support.To maintain the integral support of the cap, the longitudinal wall 32 may comprise an anchor member for interfering with the inner wall 242 of the lateral orifice 24. In this example, the anchoring member is made by two hooks 321 protruding in the longitudinal direction XX of the longitudinal wall 32. The two hooks 321 are arranged near the free bottom face 322 of the longitudinal wall. When inserting the support, these two hooks are slightly deformed and penetrate into the material of the inner cap. This connection allows good performance but is not easy to disassemble. We can consider other anchors that this one. It can be a clip crossing the headdress. It can be a series of teeth. The anchoring member may allow disassembly or not the support.

Alternativement, le support est monté libre dans la coiffe. Dans ce cas, le support reste dans son logement dès lors qu'on exerce une tension sur le support, via la sangle jugulaire. Cette tension vient plaquer la plaque 31 contre la coiffe.Alternatively, the support is mounted freely in the cap. In this case, the support remains in its housing when one exerts a tension on the support, via the jugular strap. This tension comes to press the plate 31 against the cap.

Avantageusement, le support est monté amovible sur la coiffe ce qui permet de le changer en cas de détérioration ou d'usure de la pièce ou de la sangle qui lui est associée.Advantageously, the support is removably mounted on the cap which allows to change it in case of deterioration or wear of the part or the strap associated therewith.

Selon une variante, le support peut être collé à la coiffe ou surmoulé dans celle-ci ou encore monté serrant, sans organe d'accroche particulier.According to a variant, the support may be glued to the cap or overmolded therein or else mounted tightly, without a particular fastening member.

La première fonction du support est de solidariser une extrémité de la sangle jugulaire 4 avec la coiffe 2. Pour cela, le support 3 dispose d'un moyen d'accroche 32, 33 de la sangle jugulaire. Dans cet exemple, la sangle jugulaire 4 est liée au support 3 au niveau de la paroi longitudinale 32. La plaque 31 comprend une ouverture centrale 33, sensiblement rectangulaire, dont la longueur est supérieure à la largeur de la sangle jugulaire et dont sa largeur est supérieure à la largeur de la paroi longitudinale. L'ouverture centrale 33 est positionnée et dimensionnée de manière à créer deux passages verticaux 331, un passage de part et d'autre de la paroi longitudinale 32. Autrement dit, l'ouverture centrale 33 est débouchante de la plaque 31 de chaque côté de la paroi longitudinale. Grâce à cette construction, la sangle jugulaire 4 peut entourer la paroi longitudinale 32 comme représenté à la figure 6. La sangle longe une première face latérale 323 de la paroi longitudinale 32, traverse un premier passage vertical 331, passe au-dessus de la paroi longitudinale, à l'intérieur de l'ouverture centrale 33, traverse le deuxième passage vertical 331, et longe la deuxième face latérale 323 de la paroi longitudinale, placée en opposition à la première face latérale. Enfin, l'extrémité de la sangle rejoint une portion de recouvrement de la sangle. Cette extrémité est alors fixée sur la portion de recouvrement par un moyen approprié, par exemple, par une couture 41. La sangle forme ainsi une boucle fermée, entourant la paroi longitudinale 32. Cet assemblage permet de solidariser la sangle 4 avec le support 3.The first function of the support is to secure one end of the jugular strap 4 with the cap 2. For this, the support 3 has a means of attachment 32, 33 of the jugular strap. In this example, the jugular strap 4 is connected to the support 3 at the longitudinal wall 32. The plate 31 comprises a central opening 33, substantially rectangular, whose length is greater than the width of the jugular strap and whose width is greater than the width of the longitudinal wall. The central opening 33 is positioned and dimensioned so as to create two vertical passages 331, a passage on either side of the longitudinal wall 32. In other words, the central opening 33 is opening from the plate 31 on each side of the longitudinal wall. With this construction, the jugular strap 4 can surround the longitudinal wall 32 as shown in FIG. figure 6 . The strap runs along a first lateral face 323 of the longitudinal wall 32, passes through a first vertical passage 331, passes over the longitudinal wall, inside the central opening 33, passes through the second vertical passage 331, and runs along the second lateral face 323 of the longitudinal wall, placed in opposition to the first lateral face. Finally, the end of the strap joins a lap portion of the strap. This end is then fixed on the covering portion by appropriate means, for example, by a seam 41. The strap thus forms a closed loop, surrounding the longitudinal wall 32. This assembly secures the strap 4 with the support 3.

Avantageusement, les faces latérales 323 de la paroi longitudinale 32 comprennent un évidement 34 ayant une largeur supérieure à la largeur de la sangle jugulaire. Cet évidement permet de loger la sangle afin qu'aucune partie de la sangle ne dépasse pas chaque face latérale 323 de la paroi longitudinale 32. La sangle est toujours en retrait par rapport aux faces latérales 323. Grâce à cela, la sangle ne vient pas en interférence avec la paroi interne 242 de l'orifice latéral 24 lors de l'insertion du support 3 équipé de la sangle 4. Cela facilite le montage du support sur la coiffe.Advantageously, the lateral faces 323 of the longitudinal wall 32 comprise a recess 34 having a width greater than the width of the jugular strap. This recess allows to accommodate the strap so that no part of the strap does not exceed each side face 323 of the longitudinal wall 32. The strap is always set back from the side faces 323. Because of this, the strap does not come in interference with the inner wall 242 of the lateral orifice 24 during the insertion of the support 3 equipped with the strap 4. This facilitates the mounting of the support on the cap.

D'autre part, l'ouverture centrale 33 est dimensionnée de sorte que la sangle se loge intégralement dans l'ouverture centrale 33 lorsqu'elle passe autour de la paroi longitudinale 32. Ainsi, aucune partie de la sangle ne dépasse pas la face supérieure 311 de la plaque 31. La sangle est toujours en retrait par rapport à cette face supérieure 311. Grâce à cela, la sangle n'est pas exposée et est protégée par le support 3.On the other hand, the central opening 33 is dimensioned so that the strap is fully housed in the central opening 33 when it passes around the longitudinal wall 32. Thus, no part of the strap does not exceed the face 311 of the plate 31. The strap is always set back from this upper face 311. Thanks to this, the strap is not exposed and is protected by the support 3.

En variante, on peut imaginer que le moyen d'accroche est réalisé par un trou débouchant, orienté selon la direction Y-Y, dans la largeur de la paroi longitudinale, d'une face latérale à l'autre, juste en dessous de la plaque 31. Dans ce cas, il n'est plus nécessaire d'avoir d'ouverture centrale 33 traversant la plaque 31.Alternatively, one can imagine that the attachment means is formed by a through hole, oriented in the direction YY, in the width of the longitudinal wall, from one side face to the other, just below the plate 31 In this case, it is no longer necessary to have a central opening 33 passing through the plate 31.

D'autres moyens d'accroche peuvent être envisagés. Par exemple, le support peut être surmoulé sur la sangle. On peut également transposer des solutions décrites dans l'art antérieur comme par exemple les moyens d'accroche illustrés dans les documents US 5,005,220 ; US 5,467,485 ; US 8,0911,148 ou encore US 2007/0044210 .Other means of attachment can be envisaged. For example, the support may be overmolded on the strap. It is also possible to transpose solutions described in the prior art, for example the attachment means illustrated in the documents US5,005,220 ; US 5,467,485 ; US8,0911,148 or US 2007/0044210 .

L'invention réside dans le fait que le support 3 de la sangle jugulaire 4 intègre également un élément de fixation 35 d'un accessoire.The invention lies in the fact that the support 3 of the jugular strap 4 also incorporates a fastener 35 of an accessory.

Au sens de l'invention, l'accessoire peut être un cache 5, comme représenté aux figures 1 et 5, une visière 6, comme illustré aux figures 1 et 2. L'invention n'est pas limitée à ces deux accessoires. Ce peut être également un écran optique de protection oculaire, une lampe, une décoration...Within the meaning of the invention, the accessory may be a cover 5, as shown in FIGS. figures 1 and 5 , a visor 6, as illustrated in figures 1 and 2 . The invention is not limited to these two accessories. It can also be an optical screen of eye protection, a lamp, a decoration ...

Dans l'exemple décrit, les accessoires 5, 6 sont fixés sur le support 3 par deux pions 55, 65 coopérant avec deux trous complémentaires 35 du support 3.In the example described, the accessories 5, 6 are fixed on the support 3 by two pins 55, 65 cooperating with two complementary holes 35 of the support 3.

Nous allons décrire maintenant un des pions 55 d'un cache 5, étant entendu que les autres accessoires compatibles sont également munis de pions 65 de conception analogue.We will now describe one of the pins 55 of a cover 5, it being understood that the other compatible accessories are also provided with pins 65 of similar design.

Le pion 55 fait saillie d'une surface de contact 51 sensiblement plane. Le pion 55 présente une forme sensiblement cylindrique à étage. Un premier cylindre 551, de diamètre d51 et de hauteur h51, fait saillie de la surface de contact 51 et se prolonge d'un deuxième cylindre 552 de diamètre d52 légèrement supérieur au diamètre d51. L'extrémité libre du pion 55 est bombée.The pin 55 projects from a substantially flat contact surface 51. The pin 55 has a substantially cylindrical shape with a stage. A first cylinder 551, of diameter d51 and height h51, protrudes from the contact surface 51 and is extended by a second cylinder 552 with a diameter d52 slightly greater than the diameter d51. The free end of the peg 55 is curved.

Par ailleurs, le support 3 comprend deux trous débouchants 35. Les deux trous sont positionnés symétriquement au plan médian transversal Y-Y, de part et d'autre de l'ouverture centrale 33. Les trous 35 sont positionnés de sorte qu'ils s'étendent à travers la plaque 31 et la paroi longitudinale 32. Les trous 35 débouchent ainsi sur la face supérieure 311 de la plaque 31 et sur la face inférieure libre 322 de la paroi longitudinale 32. Chaque trou 35 présente une forme sensiblement cylindrique à étage. Un premier alésage 351 s'étend de la surface supérieure 311 d'une profondeur h31, légèrement inférieure à la hauteur h51 du pion 55. Le diamètre d31 de ce premier alésage 351 est supérieur au diamètre d51 du pion 55 mais légèrement inférieur au diamètre d52 du pion 52. Ce premier alésage 351 se prolonge par un deuxième alésage 352 ayant un diamètre d32 supérieur ou égal au diamètre d52 du pion 55. La profondeur totale du trou 35 est préférentiellement supérieure à la hauteur totale du pion 55.Furthermore, the support 3 comprises two through holes 35. The two holes are positioned symmetrically to the transverse median plane YY, on either side of the central opening 33. The holes 35 are positioned so that they extend through the plate 31 and the longitudinal wall 32. The holes 35 and open on the upper face 311 of the plate 31 and on the free bottom face 322 of the longitudinal wall 32. Each hole 35 has a substantially cylindrical shape with a floor. A first bore 351 extends from the upper surface 311 of a depth h31, slightly smaller than the height h51 of the pin 55. The diameter d31 of this first bore 351 is greater than the diameter d51 of the pin 55 but slightly less than the diameter d52. of the pin 52. This first bore 351 is extended by a second bore 352 having a greater diameter d32 or equal to the diameter d52 of the peg 55. The total depth of the hole 35 is preferably greater than the total height of the peg 55.

Evidemment, l'espacement entre les deux trous 35 est identique à l'espacement entre les deux pions 55, 65 de l'accessoire de sorte à pouvoir coopérer respectivement.Obviously, the spacing between the two holes 35 is identical to the spacing between the two pins 55, 65 of the accessory so as to cooperate respectively.

Ce dimensionnement permet de solidariser l'accessoire 4, 5 avec son support 3. Lorsque l'accessoire est assemblé au support, chaque pion 55, 65 pénètre dans le trou 35 correspondant du support. Dans un premier temps, le deuxième cylindre 552 est monté légèrement serrant dans le premier alésage 351. En continuant à appuyer sur l'accessoire, le deuxième cylindre 552 s'engage alors dans le deuxième alésage 352 où il n'est plus monté serrant dans le trou 35. Dans cette configuration, la surface de contact 51 de l'accessoire vient se plaquer contre la face supérieure 311 du support. L'accessoire est maintenu sur le support de manière stable grâce à ce contact surfacique et la différence entre le diamètre d52 du deuxième cylindre 552 du pion 55 et le diamètre d31 du premier alésage 351 du trou 35. Cette différence induit que le deuxième cylindre 552 vient buter contre le premier alésage 351 dès qu'on écarte l'accessoire du support. La différence entre les hauteurs h31 et h51 définit le jeu d'assemblage et contribue également à la stabilité de l'assemblage de l'accessoire.This dimensioning makes it possible to secure the accessory 4, 5 with its support 3. When the accessory is assembled to the support, each pin 55, 65 enters the corresponding hole 35 of the support. In a first step, the second cylinder 552 is mounted slightly tightening in the first bore 351. By continuing to press on the accessory, the second cylinder 552 then engages in the second bore 352 where it is no longer mounted tightly in the hole 35. In this configuration, the contact surface 51 of the accessory is pressed against the upper face 311 of the support. The accessory is held on the support stably thanks to this surface contact and the difference between the diameter d52 of the second cylinder 552 of the pin 55 and the diameter d31 of the first bore 351 of the hole 35. This difference induces that the second cylinder 552 abuts against the first bore 351 as soon as the accessory is removed from the support. The difference between heights h31 and h51 defines the assembly clearance and also contributes to the stability of the attachment of the accessory.

Pour réaliser cet assemblage, il faut que les pions 55, 65 et/ou les trous 35 soient déformables pour que le deuxième cylindre 552 puisse traverser le premier alésage 351. De plus, ces pièces doivent être dimensionnées de sorte que le serrage entre le deuxième cylindre 552 et le premier alésage 351 soit relativement faible pour permettre à l'utilisateur la mise en place de l'accessoire sans effort. Pour faciliter l'assemblage, l'accessoire et/ou le support sont en matière plastique. Par exemple, ils sont réalisés en polyamide (PA).To achieve this assembly, it is necessary that the pins 55, 65 and / or the holes 35 are deformable so that the second cylinder 552 can pass through the first bore 351. In addition, these parts must be dimensioned so that the clamping between the second cylinder 552 and the first bore 351 is relatively small to allow the user setting up the accessory effortlessly. To facilitate assembly, the accessory and / or the support are made of plastic. For example, they are made of polyamide (PA).

Concernant le cache 5, celui-ci est dimensionné de sorte que lorsqu'il est assemblé au support 3, lui-même fixé sur la coiffe 2, sa surface enveloppe extérieure 52 complète la surface enveloppe externe S2 de la coiffe. Ainsi, une fois le cache 5 solidaire du support 3, la surface enveloppe extérieure 52 affleure ou est légèrement en retrait par rapport à la surface enveloppe externe S2 de la coiffe. Ce dimensionnement permet de ne pas pénaliser les propriétés aérodynamiques du casque. Cela implique notamment que le support est en retrait par rapport à une surface enveloppe externe de la coiffe, lorsqu'il est assemblé à la coiffe.Regarding the cover 5, it is dimensioned so that when it is assembled to the support 3, itself attached to the cap 2, its outer shell surface 52 completes the outer envelope surface S2 of the cap. Thus, once the cover 5 secured to the support 3, the outer envelope surface 52 is flush with or slightly recessed with respect to the outer envelope surface S2 of the cap. This dimensioning makes it possible not to penalize the aerodynamic properties of the helmet. This implies in particular that the support is recessed relative to an outer surface of the cap, when assembled to the cap.

Dans cet exemple, les trous 35 constituent des éléments de fixation de l'accessoire, tout comme les pions 55, 65 constituent des éléments de fixation complémentaires de l'accessoire. Cependant, l'invention n'est pas limitée à ce mode de réalisation. On peut envisager d'autres solutions alternatives pour fixer l'accessoire 5, 6 sur le support 3. Ce peut être une fixation par aimant, par clipsage, par bande adhésive, par crochets de type VELCRO ®, par bouton pression ou tout autre moyen adapté. Avantageusement, l'élément de fixation doit être conçu pour permettre un démontage facile de l'accessoire afin de le retirer et/ou le changer.In this example, the holes 35 constitute fasteners of the accessory, just as the pins 55, 65 constitute complementary fasteners of the accessory. However, the invention is not limited to this embodiment. Other alternative solutions can be envisaged for fixing the accessory 5, 6 on the support 3. It can be a fixation by magnet, by clipping, by adhesive tape, VELCRO ® hooks, snap fasteners or any other suitable means. Advantageously, the fastener must be designed to allow easy disassembly of the accessory to remove and / or change.

Comme il ressort de la description, l'accessoire est monté amovible sur le support.As is apparent from the description, the accessory is removably mounted on the support.

Pour faciliter le changement d'accessoire par l'utilisateur, l'élément de fixation est accessible depuis l'extérieur de la coiffe.To facilitate the change of accessory by the user, the fastener is accessible from outside the cap.

Dans une variante, l'invention concerne un support arrière de la sangle jugulaire, placé dans la partie postérieure de la coiffe, au niveau de l'occiput. Ce support comprend un élément de fixation d'un accessoire, au sens de l'invention. L'accessoire peut alors être un feu arrière de signalisation, un becquet permettant d'améliorer les propriétés aérodynamiques du casque ou tout autre accessoire. Cela permet de réduire le nombre de pièces constitutives du casque, comme évoqué précédemment.In a variant, the invention relates to a rear support of the jugular strap, placed in the posterior part of the cap, at the level of the occiput. This support comprises an attachment element of an accessory, within the meaning of the invention. The accessory can then be a signal rear light, a spoiler to improve the aerodynamic properties of the helmet or any other accessory. This reduces the number of constituent parts of the helmet, as mentioned above.

L'invention couvre ainsi un casque de sport muni de support(s) dans la partie antérieure de la coiffe et/ou dans la partie postérieure de la coiffe.The invention thus covers a sports helmet provided with support (s) in the front part of the cap and / or in the posterior part of the cap.

L'invention n'est pas limitée à ces modes de réalisation. Il est possible de combiner ces modes de réalisation.The invention is not limited to these embodiments. It is possible to combine these embodiments.

L'invention n'est pas limitée au mode de réalisation précédemment décrit mais s'étend à tous les modes de réalisation couverts par les revendications annexées.The invention is not limited to the embodiment previously described but extends to all the embodiments covered by the appended claims.
