Description

La présente invention concerne un casque de protection et plus particulièrement les moyens de maintien dudit casque, ainsi que les dispositifs de réglage desdits moyens de maintien et notamment une jugulaire destinée à la fixation du casque sur la tête de son utilisateur.The present invention relates to a protective helmet and more particularly the means for holding said helmet, as well as the adjustment devices of said holding means and in particular a chin strap for fixing the helmet on the head of the user.

On connaít déjà des casques de protection qui sont utilisés dans différents domaines et portés par des utilisateurs divers tels que les cyclistes, les motocyclistes, les sapeurs pompiers, les skieurs et autres, tels que les soldats, les pilotes d'avions ou d'hélicoptères. Tous les casques actuels, quelle que soit leur utilisation, comprennent une coque rigide externe ayant la forme générale d'une sphère comprenant une ouverture faciale et dont la cavité ainsi formée comprend des éléments de rembourrage de protection et de confort destinés à emboíter la tête de l'utilisateur. Par ailleurs, le casque est retenu traditionnellement sur la tête de l'utilisateur par des moyens de maintien, comme par exemple une jugulaire souple fixée aux parties latérales du casque. Les dispositif actuels de liaison de la jugulaire sont totalement insatisfaisants car inefficaces, souvent peu fiables, et sont très inesthétiques. Le retrait ou la mise en place du casque est la plupart du temps assez difficile, le réglage en est délicat et bien souvent ne permet pas un bon positionnement et une bonne retenue. Le casque est alors un objet d'inconfort pour le porteur et il n'assure pas sa fonction de protection dans de bonnes conditions.We already know protective helmets that are used in different domains and worn by diverse users such as cyclists, motorcyclists, firefighters, skiers and others, such than soldiers, pilots of airplanes or helicopters. All helmets whatever their use, include a rigid shell external having the general shape of a sphere comprising an opening facial and whose cavity thus formed comprises elements of protective and comfort padding intended to fit the head the user. In addition, the helmet is traditionally held on the head of the user by holding means, such as for example a flexible chin strap attached to the side parts of the helmet. Current devices chin strap are totally unsatisfactory because ineffective, often unreliable, and are very unsightly. The withdrawal or the setting in helmet position is most of the time quite difficult, the adjustment is delicate and very often does not allow good positioning and good restraint. The helmet is then an object of discomfort for the wearer and it does not perform its protective function under good conditions.

De plus, une fois le casque mis en place et serré sur la tête de l'utilisateur, il présente des extrémités de sangle laissée libre qui peuvent gêner leur porteur dans ses évolutions.In addition, once the helmet is put on and tightened on the head user, it has strap ends left free which can hinder their wearer in their development.

Ainsi, la présente invention a pour but de remédier aux inconvénients précités à l'aide de moyens plus simples, fiables et faciles à mettre en oeuvre. La présente invention a de ce fait, pour objectif de renforcer le maintien du casque tout en accroissant le confort pour l'utilisateur en affinant le réglage et le positionnement dudit casque sur sa tête. De plus, il permet avantageusement de supprimer toutes les portions de sangle superflues laissées libres avec des réglages de type classique.Thus, the present invention aims to remedy the disadvantages mentioned above using simpler, reliable and easy to enforce. The present invention therefore aims to reinforce the support of the helmet while increasing comfort for the user by refining the adjustment and positioning of said helmet on his head. In addition, it advantageously makes it possible to remove all the portions of superfluous strap left free with classic adjustments.

Selon la caractéristique principale du casque de protection selon l'invention, celui-ci est formé par une coque externe principale qui comporte un plan de symétrie longitudinal et est du type comportant des moyens de maintien et de positionnement destinés à permettre sa fixation sur la tête de l'utilisateur, lesdits moyens comportant un ensemble de sangles souples, et est caractérisé en ce que les moyens de maintien et de positionnement comportent des moyens de réglage de la longueur des sangles, dont au moins un des moyens est constitué par un mouflage.According to the main characteristic of the protective helmet according to the invention, it is formed by a main external shell which has a longitudinal plane of symmetry and is of the type with holding and positioning means intended to allow its attachment to the head of the user, said means comprising a set of flexible straps, and is characterized in that the means of holding and positioning comprise means for adjusting the length of the straps, at least one of the means of which consists of a hauling.

Selon un mode de réalisation du casque de protection selon l'invention, les moyens de maintien et de positionnement comprennent une jugulaire, constituée par un ensemble de sangles souples, la jugulaire étant ainsi constituée par une sangle avant et une sangle arrière se rejoignant dans leur partie centrale, tandis que la sangle avant est constituée d'une portion gauche de sangle avant et d'une portion droite de sangle avant et que la sangle arrière est constituée par une portion gauche de sangle arrière et une portion droite de sangle arrière, les portions gauches étant reliées à un point de concours, tandis que les portions droites sont également reliées à un point de concours, lesdits points de concours étant destinés à être reliés entre eux pour fixer le casque.According to one embodiment of the protective helmet according to the invention, the holding and positioning means comprise a chinstrap, consisting of a set of flexible straps, the chinstrap thus being constituted by a front strap and a rear strap joining in their central part, while the front strap is consisting of a left portion of front strap and a right portion front strap and the rear strap is made up of a portion left of rear strap and a right portion of rear strap, left portions being connected to a competition point, while the straight portions are also connected to a competition point, said competition points being intended to be linked together to fix the helmet.

Selon une caractéristique complémentaire du casque de protection selon l'invention, celui-ci est caractérisé en ce que chacune des portions de sangles comprend des moyens de réglage en longueur.According to an additional characteristic of the helmet protection according to the invention, this is characterized in that each portions of straps include length adjusting means.

Selon une autre caractéristique, le casque de protection est caractérisé en ce que chacun des moyens de réglage des portions de sangle est constitué par un mouflage.According to another characteristic, the protective helmet is characterized in that each of the means for adjusting the portions of strap is constituted by hauling.

Selon une variante d'exécution du casque de protection, chaque mouflage est constitué par une boucle à levier disposé sur une portion de sangle et par une boucle de rappel complémentaire fixée à la coque externe principale du casque au niveau du point d'accrochage de la portion de sangle à la coque.According to a variant of the protective helmet, each hauling is constituted by a lever loop arranged on a portion of strap and an additional return loop attached to the shell main external of the helmet at the point of attachment of the portion of hull strap.

Selon cette variante d'exécution, la portion de sangle passe dans le mouflage en partant d'abord de son point d'accrochage à la coque externe principale pour passer dans un passant de la boucle à levier puis pour revenir passer dans la boucle de rappel complémentaire avant de repasser ensuite de manière coulissante sous le bras de levier pivotant qui est susceptible de bloquer ledit coulissement.According to this variant, the strap portion passes through hauling starting first from its point of attachment to the hull main external to pass in a loop of the lever loop then to go back go into the additional recall loop before then slide back under the pivoting lever arm which is likely to block said sliding.

Selon une autre caractéristique du casque de protection selon l'invention, l'ensemble des sangles souples comporte une sangle avant et une sangle arrière qui est formée par une portion de sangle gauche et une portion de sangle droite et en ce que la liaison des extrémités des portions gauche et droite de sangle arrière avec la coque se fait grâce à une pièce intermédiaire de liaison ayant la forme d'un Y inversé.According to another characteristic of the protective helmet according to the invention, the set of flexible straps includes a front strap and a rear strap which is formed by a portion of the left strap and a portion of straight strap and in that the binding of the ends of the left and right portions of rear strap with the shell is made thanks to an intermediate connecting piece in the form of an inverted Y.

Par ailleurs, selon une variante d'exécution du casque de protection, celui-ci est caractérisé en ce que la pièce intermédiaire de liaison arrière est semi rigide et en ce qu'elle est articulée autour de son point de fixation à la coque dans un plan transversal orthogonal au plan longitudinal de symétrie, de manière à pouvoir épouser la nuque de l'utilisateur.Furthermore, according to an alternative embodiment of the helmet of protection, this is characterized in that the intermediate piece of rear link is semi rigid and in that it is articulated around its attachment point to the hull in a plane transverse to the plane longitudinal symmetry, so as to be able to marry the nape of the user.

Selon une autre caractéristique du casque de protection selon l'invention, la jugulaire comprend au moins une boucle automatique de connexion et de déconnexion, cette boucle automatique, et plus particulièrement la zone de sa connexion, étant disposée au point de concours de la portion gauche de la sangle avant avec la portion gauche de la sangle arrière. According to another characteristic of the protective helmet according to the invention, the chinstrap comprises at least one automatic loop of connection and disconnection, this automatic loop, and more particularly the area of its connection, being arranged at the point of competition of the left portion of the front strap with the left portion of the back strap.

Le casque de protection représenté à titre d'exemple aux figures 1 à 12 portant la référence générale (1) est notamment un casque de soldat, du type fantassin, qui présente un plan longitudinal de symétrie générale (P) qui comprend de façon connue en soi une coque externe principale (2) présentant une ouverture faciale avant (3). The protective helmet shown as an example in Figures 1 to 12 bearing the general reference (1) is in particular a soldier's helmet, of the infantryman type, which has a longitudinal plane of general symmetry (P) which comprises in a manner known per se a main external shell (2) having a front facial opening (3).

La coque externe principale (2) est constituée par une paroi sensiblement sphérique de plan général vertical de symétrie (P) qui est réalisée avantageusement en matériau composite du type comprenant un empilage de couches de fibres de renfort, imprégnées et liées entre elles par une matrice en résine. Les fibres peuvent être des fibres de verre, d'aramide, de Nylon, de polyéthylène ou de carbone, tandis que la matrice peut être une résine du type thermodurcissable ou thermoplastique. Bien entendu, la coque pourrait être en tout autre matériau comme, par exemple, en acier.The main external shell (2) is constituted by a wall substantially spherical with a general vertical plane of symmetry (P) which is advantageously made of composite material of the type comprising a stacking layers of reinforcing fibers, impregnated and bonded together by a resin matrix. The fibers can be glass fibers, aramid, nylon, polyethylene or carbon, while the matrix may be a resin of the thermosetting type or thermoplastic. Of course, the hull could be quite different material such as, for example, steel.

La coque externe principale (2) comprend plusieurs portions de paroi, comme le montre la figure 3, à savoir une portion avant supérieure de paroi (4) prolongée vers l'arrière par une portion arrière supérieure de paroi (5), elle-même prolongée vers le bas par une portion arrière inférieure de paroi (6), et comprend, par ailleurs, deux portions latérales de paroi (7). La portion avant supérieure (4) correspond à la zone occupée par le front de l'utilisateur et est limitée par la bordure supérieure (8) de l'ouverture faciale (3) qui, quant à elle, est limitée latéralement par deux bordures latérales (9). La portion arrière supérieure de paroi (5) correspond à la zone occupée par la boíte crânienne de l'utilisateur, tandis que la portion arrière inférieure de paroi (6) correspond à la zone occupée par la nuque de l'utilisateur. Ajoutons à cela que la paroi de la coque est limitée vers le bas par une bordure inférieure (10). Les portions latérales de paroi (7) correspondent aux zones occupées par les oreilles de l'utilisateur et sont limitées vers l'avant par la bordure latérale correspondante (9) de l'ouverture faciale (3) et vers le bas par la bordure inférieure (10).The main external shell (2) comprises several portions of wall, as shown in Figure 3, namely an upper front portion wall (4) extended rearwards by an upper rear portion wall (5), itself extended downwards by a rear portion lower wall (6), and further comprises two lateral portions wall (7). The upper front portion (4) corresponds to the zone occupied by the user's forehead and is limited by the border upper (8) of the facial opening (3) which, in turn, is limited laterally by two lateral edges (9). The upper rear portion wall (5) corresponds to the area occupied by the cranium the user, while the lower rear wall portion (6) corresponds to the area occupied by the user's neck. Let's add to that the hull wall is bounded down by a border lower (10). The lateral wall portions (7) correspond to the areas occupied by the user's ears and are limited towards the front by the corresponding lateral border (9) of the facial opening (3) and down by the lower edge (10).

Par ailleurs et comme le montre la figure 7, l'enceinte interne de la coque principale (2) comprend un calotin (20) constitué, par exemple, par une couche de mousse collée sur la face intérieure de la coque ainsi qu'une coiffe déformable (21) destinée à l'adaptation du casque au volume et à la forme de la tête de l'utilisateur. Ladite coiffe déformable est, par exemple, constituée par un ensemble d'éléments (22) en matériaux souples tels qu'en cuir, sangle ou similaire, retenu sur un support de coiffe (24) fixé à la coque (2). Furthermore and as shown in FIG. 7, the internal enclosure of the main shell (2) comprises a cap (20) made, for example, by a layer of foam glued to the inside of the shell as well a deformable cap (21) intended for adapting the helmet to volume and shape of the user's head. Said deformable cap is, for example, constituted by a set of elements (22) in flexible materials such as leather, strap or similar, retained on a cap support (24) fixed to the shell (2).

Selon l'invention, le casque de protection (1) comporte des moyens de maintien et de positionnement destinés à permettre son ajustement et sa fixation sur la tête (100) de l'utilisateur, lesdits moyens comportant une jugulaire (11) et un bandeau d'ajustement (23) de la coiffe déformable (21). La jugulaire (11) est constituée par un ensemble de sangles souples, à savoir, une sangle avant (12) et une sangle arrière (13) se rejoignant dans leur partie centrale. Le bandeau (23) est disposé dans la coiffe (21) de manière à permettre l'ajustement de la tête de l'utilisateur à l'intérieur de ladite coiffe.According to the invention, the protective helmet (1) includes holding and positioning means intended to allow its adjustment and its attachment to the head (100) of the user, said means comprising a chin strap (11) and an adjustment band (23) of the deformable cap (21). The chin strap (11) consists of a set flexible straps, namely, a front strap (12) and a back strap (13) meeting in their central part. The strip (23) is arranged in the cap (21) so as to allow adjustment of the head of the user inside said cap.

Selon l'invention, les moyens de maintien comportent des moyens de réglage de la longueur des sangles (12, 13), lesdits moyens de réglage comportant au moins un mouflage (70) constitué par une boucle à levier (15, 16) disposée sur la sangle et par une boucle de rappel complémentaire (18).According to the invention, the holding means comprise means for adjusting the length of the straps (12, 13), said means for adjustment comprising at least one haul (70) constituted by a loop lever (15, 16) arranged on the strap and by a return loop complementary (18).

Selon le mode de réalisation préféré du casque (1) et de sa jugulaire (11), la sangle avant (12) est constituée d'une portion gauche (12a) de sangle avant et d'une portion droite (12b) de sangle avant, tandis que la sangle arrière (13) est constituée par une portion gauche (13a) de sangle arrière et une portion droite (13b) de sangle arrière, tel qu'illustré figures 2 et 3.According to the preferred embodiment of the helmet (1) and its chin strap (11), the front strap (12) consists of a left portion (12a) of front strap and of a straight portion (12b) of front strap, while the rear strap (13) is constituted by a left portion (13a) of rear strap and a straight portion (13b) of rear strap, such as illustrated in Figures 2 and 3.

Selon une caractéristique du mode de réalisation illustré de l'invention, les extrémités des portions gauche (12a) et droite (12b) de sangle avant (12) sont fixées à des points de fixation (X) à la bordure supérieure de l'ouverture faciale à proximité des bordures latérales (8) de la coque externe principale, tandis que les extrémités des portions gauche (13a) et droite (13b) de sangle arrière (13) sont fixées au centre et à l'arrière de la bordure inférieure (10).According to a characteristic of the illustrated embodiment of the invention, the ends of the left (12a) and right (12b) portions of front strap (12) are attached to fixing points (X) at the border upper face opening near the side edges (8) of the main outer shell, while the ends of the left portions (13a) and right (13b) of rear strap (13) are fixed in the center and at the back of the lower border (10).

Par ailleurs, les autres extrémités des portions de sangles droites avant et arrière (12b, 13b) sont fixées ensemble en un point de concours (50), les extrémités des portions gauches se rejoignant respectivement au point de concours (51). Les deux points de concours (50, 51) sont avantageusement destinés à être reliés ensemble par une ou plusieurs portions complémentaires de sangle (53), destinée(s) à passer sous le menton ou à entourer le menton de l'utilisateur pour fixer le casque (1), comme le montre la figure 4.Furthermore, the other ends of the portions of straight straps front and rear (12b, 13b) are fixed together at a competition point (50), the ends of the left portions respectively joining at competition point (51). The two competition points (50, 51) are advantageously intended to be connected together by one or more additional portions of strap (53), intended to pass under the chin or surround the user's chin to fix the helmet (1), as shown in figure 4.

Par ailleurs, la jugulaire (11) peut être ouverte pour permettre la mise en place du casque et refermée pour assurer la retenue de ce dernier sur la tête de l'utilisateur. A cet effet, la jugulaire comprend au moins une boucle automatique (19) de connexion et de déconnexion, destinée à permettre la libération de la (des) portion(s) de sangle(s) complémentaire(s) (53). Selon une disposition avantageuse, cette boucle automatique, et plus particulièrement, la zone de connexion, est disposée au point de concours (51) de la portion gauche (12a) de la sangle avant (12) avec la portion gauche (13a) de la sangle arrière (13), tel qu'illustré figure 3.Furthermore, the chin strap (11) can be opened to allow the fitting of the helmet and closed to ensure the retention of the latter on the user's head. For this purpose, the chinstrap includes at least one automatic connection and disconnection loop (19), intended for allow release of the portion (s) of strap (s) complementary (s) (53). According to an advantageous arrangement, this loop automatic, and more particularly, the connection area, is arranged at the competition point (51) of the left portion (12a) of the front strap (12) with the left portion (13a) of the rear strap (13), as illustrated figure 3.

Selon le mode de réalisation préféré du casque de protection, selon l'invention, chacune des portions de sangles comprend des moyens de réglage en longueur, comme le montrent les figures 2 et 3.According to the preferred embodiment of the protective helmet, according to the invention, each of the strap portions comprises length adjustment means, as shown in Figures 2 and 3.

Ainsi, la portion gauche (12a) de la sangle avant (12) comprend un moyen de réglage en longueur (15a), tandis que la portion droite (12b) de la sangle avant comprend aussi un moyen de réglage en longueur (15b). De même, la portion gauche (13a) de la sangle arrière (13) comprend un moyen de réglage (16a), tandis que la portion droite (13b) de ladite sangle comprend aussi un moyen de réglage en longueur (16b).Thus, the left portion (12a) of the front strap (12) comprises a length adjustment means (15a), while the straight portion (12b) of the front strap also includes means for adjusting length (15b). Similarly, the left portion (13a) of the rear strap (13) comprises an adjustment means (16a), while the straight portion (13b) of said strap also includes a length adjustment means (16b).

Chacune des portions de sangles (12a, 12b, 13a, 13b) est une portion continue de longueur finie reliant un point de concours (50, 51) à un point d'accrochage solidaire de la coque externe principale (2). Leurs moyens de réglage (15a, 15b, 16a, 16b), illustrés notamment aux figures 9a, 9b et 10, sont constitués chacun par un ensemble boucle à levier (15, 16) et boucle de rappel complémentaire (18) qui forment une sorte de moufle ou de mouflage (70) qui permettent de régler la longueur utile des portions de sangles respectives sur lesquelles elles sont disposées.Each of the strap portions (12a, 12b, 13a, 13b) is a continuous portion of finite length connecting a competition point (50, 51) to a point of attachment secured to the main external shell (2). Their adjustment means (15a, 15b, 16a, 16b), illustrated in particular in FIGS. 9a, 9b and 10, each consist of a lever loop assembly (15, 16) and complementary return loop (18) which form a sort of muffle or hauling (70) which allow the useful length of the respective portions of straps on which they are arranged.

Ainsi, on notera que la portion de sangle (12a, 12b, 13a, 13b) part de son point d'accrochage pour passer dans une boucle ou passant (17) de la boucle à levier (15, 16) avant de revenir passer dans la boucle de rappel complémentaire (18) solidaire dudit point d'accrochage et fixe par rapport à celui-ci, puis vient coulisser sous le bras de levier pivotant (73) de la boucle à levier (15, 16) de façon à pouvoir être bloqué par celui-ci de manière connue en soi, tel qu'illustré aux figures 9a et 10. Notons que la figure 9b illustre le coulissement de la boucle de levier (15b) pour l'amener dans une position de réglage différente de celle illustrée figure 9a, le levier pivotant étant en position ouverte autorisant le coulissement.Thus, it will be noted that the strap portion (12a, 12b, 13a, 13b) leaves from its point of attachment to pass in a loop or passing (17) of the lever loop (15, 16) before returning to pass through the loop of additional reminder (18) integral with said attachment point and fixed relative to it, then slides under the pivoting lever arm (73) of the lever loop (15, 16) so that it can be locked by this in a manner known per se, as illustrated in FIGS. 9a and 10. Note that Figure 9b illustrates the sliding of the lever loop (15b) to bring it into an adjustment position different from that illustrated in FIG. 9a, the pivoting lever being in the open position allowing the sliding.

Afin d'obtenir un meilleur positionnement du casque de protection (1) sur la tête (100) de l'utilisateur, la liaison des extrémités des portions gauche et droite des sangles arrières avec la coque se fait grâce à une pièce intermédiaire de liaison (14) ayant la forme d'un Y inversé.In order to obtain a better positioning of the helmet protection (1) on the head (100) of the user, the connection of the ends left and right portions of the rear straps with the shell are made thanks to an intermediate connecting piece (14) having the shape of a Y reversed.

Comme le montre la figure 5, la pièce de liaison (14) est fixée sur la portion inférieure arrière (6) de la coque principale externe (2) du casque (1) à proximité de la bordure inférieure (10), elle est avantageusement articulée autour de son point de fixation (X,75), dans un plan transversal orthogonal au plan longitudinal de symétrie (P). La pièce de liaison est avantageusement réalisée par l'assemblage de deux pièces en forme de Y, une pièce externe réalisée dans un matériau semi rigide tel qu'un cuir relativement dur et une pièce interne destinée à venir en appui au sommet de la nuque de l'utilisateur et qui est réalisée dans un matériau relativement mou, comme par exemple, un rembourrage dans une enveloppe en cuir souple.As shown in Figure 5, the connecting piece (14) is fixed on the lower rear portion (6) of the outer main shell (2) of the helmet (1) near the lower edge (10), it is advantageously articulated around its fixing point (X, 75), in a transverse plane orthogonal to the longitudinal plane of symmetry (P). The room of connection is advantageously carried out by the assembly of two parts Y-shaped, an external part made of semi-rigid material such as a relatively hard leather and an internal part intended to come in support at the top of the user's neck and which is performed in a relatively soft material, such as padding in a soft leather envelope.

L'assemblage des pièces internes et externes s'effectue par exemple par des coutures, lesdites coutures permettant notamment une fixation solide et fiable des portions de sangle arrière (13a, 13b) et des boucles de rappel complémentaires (18), sur la pièce de liaison (14). Notons que la pièce de liaison, ainsi constituée est semi rigide et est ainsi susceptible de se plier légèrement et de pivoter autour de son point de fixation de manière à pouvoir épouser la nuque de l'utilisateur.The assembly of internal and external parts is carried out by example by seams, said seams allowing in particular a solid and reliable fixing of the rear strap portions (13a, 13b) and complementary return loops (18), on the connecting piece (14). Note that the connecting piece, thus formed is semi rigid and is thus likely to bend slightly and pivot around its point of fixation so that it can fit the neck of the user.

Selon le mode de réalisation préféré du casque de protection, selon l'invention, les moyens de maintien et de positionnement du casque comprennent un bandeau d'ajustement (23) disposé dans la coiffe déformable (21) destiné à enserrer le tour de tête de l'utilisateur. Le bandeau comprend un système d'ajustement rapide (230) destiné à faciliter une utilisation, par exemple, avec un masque à gaz. Ledit système d'ajustement permet d'ajouter au bandeau une largeur supplémentaire sans modification de l'ajustement principal du bandeau. A cet effet, il est prévu une languette mobile de recouvrement (231) solidaire du bandeau comprenant l'une des parties (232a) d'un dispositif auto-agrippant dont la partie auto-agrippante correspondante (232b) est disposée sur la bandeau tel qu'illustré aux figures 11 et 12. Ainsi, on peut totalement libérer la languette comme cela est représenté figure 12 par dégagement des parties autoagrippantes et augmenter ainsi la longueur du bandeau. En position initiale fermée représentée figure 11, les deux parties autoagrippantes se recouvrent en partie, une portion (80) de la partie agrippante. (232b) étant repliée, afin de permettre l'agrandissement du bandeau.According to the preferred embodiment of the protective helmet, according to the invention, the means for holding and positioning the helmet include an adjustment band (23) arranged in the cap deformable (21) intended to enclose the head circumference of the user. The strip includes a quick adjustment system (230) for facilitate use, for example, with a gas mask. Said system adjustment allows you to add additional width to the headband without modifying the main adjustment of the headband. For this purpose, it is provided with a movable cover tab (231) integral with the strip comprising one of the parts (232a) of a hook-and-loop device of which the corresponding hook-and-loop part (232b) is arranged on the headband as illustrated in Figures 11 and 12. Thus, we can totally release the tab as shown in figure 12 by release Velcro parts and thus increase the length of the strip. In the closed initial position shown in FIG. 11, the two hook-and-loop parts partially overlap, a portion (80) of the portion gripping. (232b) being folded up, to allow the enlargement of the headband.

Par ailleurs, il est important de noter que le bandeau comporte également un réglage destiné à permettre le réglage de la position initiale du bandeau, ledit réglage pouvant être constitué de manière connue en soi par un dispositif auto-agrippant situé sur chacune des deux extrémités du bandeau.. Ainsi, une fois le réglage initial effectué, le système d'ajustement rapide permet d'agrandir le tour du bandeau sans en modifier le réglage initial.It is also important to note that the banner includes also an adjustment intended to allow the adjustment of the position initial of the strip, said adjustment being able to be constituted so known per se by a hook-and-loop device located on each of the two ends of the strip. So, once the initial adjustment has been made, the quick adjustment system allows you to enlarge the headband without change the initial setting.

L'ensemble des différentes caractéristiques, à savoir les mouflages, la pièce arrière de liaison, les moyens de réglage disposés sur chacune des portions de sangle, la configuration spécifique de la jugulaire ainsi que l'ajustement rapide du bandeau concourent à améliorer sensiblement le confort et le positionnement du casque, ainsi qu'à faciliter sa mise en place, toutefois, chacune de ces caractéristiques est susceptible de constituer une invention en soi.The set of different characteristics, namely hauling, the rear connecting part, the adjustment means arranged on each portions of the strap, the specific configuration of the chinstrap as well that the quick adjustment of the headband help to significantly improve the comfort and positioning of the helmet, as well as facilitating its fitting place, however, each of these characteristics is likely to constitute an invention in itself.

Bien entendu, l'invention n'est pas limitée aux modes de réalisation décrits et représentés à titre d'exemples, mais elle comprend aussi tous les équivalents techniques ainsi que leurs combinaisons.Of course, the invention is not limited to the modes of realization described and represented as examples, but it includes also all technical equivalents and their combinations.
