Description

Masque pour casque Helmet mask
La présente invention se rapporte à un dispositif de ventilation pour casque, notamment pour motocycliste et/ou motoneigiste, comprenant un masque spécialement adapté pour permettre une ventilation à l'intérieur du casque.The present invention relates to a helmet ventilation device, in particular for a motorcyclist and / or snowmobiler, comprising a mask specially adapted to allow ventilation inside the helmet.
Des dispositifs du type précité sont connus dans l'état de la technique, notamment dans le document GB 2186490 qui présente une évacuation d'air latérale, ainsi que dans US 5 758 639.Devices of the aforementioned type are known in the state of the art, in particular in document GB 2186490 which presents a lateral air evacuation, as well as in US 5,758,639.
Certains autres documents notamment EP 0 371 858 décrivent également des dispositifs du type précité mais se rapportent à des masques destinés à un tout autre usage que celui des motocyclistes, à savoir dans le secteur aéronautique, répondant ainsi à des contraintes fort différentes.Certain other documents, in particular EP 0 371 858 also describe devices of the aforementioned type but relate to masks intended for any use other than that of motorcyclists, namely in the aeronautical sector, thus meeting very different constraints.
La présente invention vise à fournir un dispositif de ventilation pour casque, destiné essentiellement à un usage pour motocyclistes pouvant être actionné de façon commode par l'utilisateur, porteur du casque.The present invention aims to provide a helmet ventilation device, intended essentially for use for motorcyclists which can be actuated conveniently by the user wearing the helmet.
Ce but est atteint par le dispositif suivant la présente invention comprenant un masque qui comprend un élément formant membrane, lequel est remarquable en ce que le masque présente un conduit d'évacuation unique orienté vers le bas. Ainsi, l'air expiré par le porteur du casque est évacué de façon plus naturelle et permet en outre une simplification constructive considérable du dispositif grâce à la sortie unique de type trompe orientée vers le bas. La sortie d'évacuation telle que proposée permet de contrer la formation de buée sur la visière du casque de façon à assurer une parfaite visibilité pour l'utilisateur. Ainsi, grâce au dispositif suivant l'invention on obtient une bonne canalisation et évacuation de l'air exhalé par le porteur du casque. Suivant un mode de réalisation avantageux de l'invention, la membrane est monobloc, le conduit d'évacuation étant intégré à cette dernière avec agencement sensiblement central de celui-ci. Ainsi, lorsque le masque est positionné sur le visage de l'utilisateur, le conduit d'évacuation est sensiblement en alignement avec les orifices d'exhalation.This object is achieved by the device according to the present invention comprising a mask which comprises a membrane-forming element, which is remarkable in that the mask has a single downwardly directed evacuation duct. Thus, the air exhaled by the wearer of the helmet is evacuated in a more natural way and also allows a considerable constructive simplification of the device thanks to the unique outlet of the downward-facing proboscis type. The exhaust outlet as proposed makes it possible to counter the formation of fogging on the visor of the helmet so as to ensure perfect visibility for the user. Thus, thanks to the device according to the invention, good ducting and evacuation of the air exhaled by the wearer of the helmet is obtained. According to an advantageous embodiment of the invention, the membrane is in one piece, the evacuation duct being integrated into the latter with a substantially central arrangement thereof. Thus, when the mask is positioned on the face of the user, the exhaust duct is substantially in alignment with the exhalation orifices.
Suivant un mode de réalisation particulièrement avantageux de l'invention, le conduit d'évacuation présente une surface d'enveloppe intérieure sensiblement lisse, de sorte qu'aucune charge de condensation ne peut se former sur la paroi de celui-ci, contrairement à certains systèmes existants englobant des évacuations latérales à soufflet risquant d'entraîner une retenue d'eau par condensation dans les creux. Ce dernier cas présente l'inconvénient que de la condensation pourra se former dans les creux provenant de l'air exhalé par l'utilisateur du casque. Toute forme de condensation peut se transformer en glaçon, notamment en altitude, ce qui peut conduire à une réduction du diamètre utile du conduit d'évacuation ayant inévitablement une incidence défavorable sur la prise d'oxygène par l'utilisateur, surtout en altitude où l'oxygène est raréfié.According to a particularly advantageous embodiment of the invention, the evacuation duct has a substantially smooth interior envelope surface, so that no condensation charge can form on the wall thereof, unlike some existing systems including lateral bellows drains which could cause water retention by condensation in the hollows. The latter case has the disadvantage that condensation may form in the hollows from the air exhaled by the user of the helmet. Any form of condensation can turn into an ice cube, especially at altitude, which can lead to a reduction in the useful diameter of the evacuation duct which inevitably has an unfavorable impact on the oxygen uptake by the user, especially at altitude where the oxygen is rarefied.
En outre, le caractère entièrement lisse de la paroi précitée combinée à l'orientation vers le bas du conduit d'évacuation favorise encore davantage l'absence de formation de condensation aux motifs précités. En effet, grâce à l'orientation vers le bas du conduit, toute condensation éventuelle sur les parois aura une tendance naturelle à s'évacuer vers le bas sous l'effet de la gravité.In addition, the entirely smooth character of the aforementioned wall combined with the downward orientation of the exhaust duct further favors the absence of formation of condensation on the aforementioned patterns. Indeed, thanks to the downward orientation of the conduit, any possible condensation on the walls will have a natural tendency to drain downward under the effect of gravity.
Cela est encore renforcé par le fait que le conduit d'évacuation présente un profil sensiblement incurvé, l'incurvation étant de nature à rabattre le conduit d'évacuation vers la verticale, c'est-à-dire avec effet de gravité maximal. Le profil incurvé du conduit d'évacuation permet d'optimiser cette évacuation. En conférant une pente au conduit, l'évacuation de la condensation éventuelle sera favorisée. Cet aspect est particulièrement critique ici car l'utilisateur est fréquemment soumis à des efforts physiques importants et est donc susceptible de dégager une forte condensation.This is further reinforced by the fact that the evacuation conduit has a substantially curved profile, the bending being of a nature to fold the evacuation conduit towards the vertical, that is to say with maximum gravity effect. The curved profile of the evacuation pipe makes it possible to optimize this evacuation. By giving a slope to the duct, the evacuation of any condensation will be favored. This aspect is particularly critical here because the user is frequently subjected to significant physical efforts and is therefore likely to give off strong condensation.
Suivant un mode de réalisation plus avantageux encore de l'invention, la section transversale du conduit d'évacuation présente une allure aplatie, de préférence sensiblement elliptique. Ceci constitue un avantage fonctionnel du point de vue du positionnement du masque par rapport au casque et de la contrainte d'espace très critique dans la conception des casques. Il en résulte que le conduit d'évacuation doit être le moins encombrant possible tout en assurant une optimisation d'évacuation.According to an even more advantageous embodiment of the invention, the cross section of the evacuation duct has a flattened appearance, preferably substantially elliptical. This constitutes a functional advantage from the point of view of the positioning of the mask relative to the helmet and the very critical space constraint in the design of the helmets. As a result, the evacuation duct must be as compact as possible while ensuring optimization of evacuation.
Le dispositif suivant l'invention ayant été conçu au départ pour être adapté à un casque de moto, la contrainte d'espace disponible était particulièrement importante. En effet, il est connu que l'espace disponible pour les casques à moto est limité, ce qui a conduit à sélectionner l'évacuation la moins encombrante possible. La forme aplatie mais de préférence sensiblement elliptique permet de rencontrer la contrainte d'espace avec un encombrement de profondeur réduit tout en préservant un flux optimal d'écoulement de l'air exhalé.The device according to the invention having been designed at the outset to be adapted to a motorcycle helmet, the space constraint available was particularly important. Indeed, it is known that the space available for motorcycle helmets is limited, which has led to selecting the least bulky evacuation possible. The flattened but preferably substantially elliptical shape makes it possible to meet the space constraint with a reduced depth dimension while preserving an optimal flow of flow of the exhaled air.
Suivant un mode de réalisation préféré de l'invention, le dispositif d'évacuation comprend essentiellement deux éléments: une membrane souple et monobloc sans surface interne saillante avec un conduit d'évacuation, d'une part, et un capot semi-rigide prévu contre tout impact extérieur éventuel, d'autre part. Le capot est agencé en aval de la membrane. Il est réalisé en un matériau de rigidité plus importante que celui de la membrane. Des moyens de fixation du capot sur la membrane sont prévus pour la fixation mutuelle. Grâce à la présence du capot, l'ensemble peut être parfaitement adapté sur le visage de l'utilisateur en améliorant le confort pour ce dernier, le capot servant d'élément récepteur de pression exercée par le casque.According to a preferred embodiment of the invention, the evacuation device essentially comprises two elements: a flexible, monobloc membrane without protruding internal surface with an evacuation duct, on the one hand, and a semi-rigid cover provided against any possible external impact, on the other hand. The cover is arranged downstream of the membrane. It is made of a material of greater rigidity than that of the membrane. Means for fixing the cover to the membrane are provided for mutual fixing. Thanks to the presence of the cover, the assembly can be perfectly adapted to the face of the user by improving comfort for the latter, the cover serving as a pressure receptor element exerted by the helmet.
Ainsi, dans un mode de réalisation spécifique de l'invention, la me m- brane présente une allure creuse de façon à être adaptée à la morphologie du visage, le capot s'emboîtant ensuite sur la membrane, extérieurement à celle-ci.Thus, in a specific embodiment of the invention, the me m- brane has a hollow appearance so as to be adapted to the morphology of the face, the cover then fitting onto the membrane, outside of it.
Dans un mode de réalisation plus spécifique encore du dispositif suivant l'invention, la surface de sommet du conduit d'évacuation s'étend dans le prolongement de la membrane. Ce mode de réalisation s'inscrit en particulier dans le cadre du conduit d'évacuation d'allure aplatie, de préférence sensiblement elliptique précité. L'ensemble s'inscrit en adéquation parfaite avec la contrainte d'espace imposée par le casque.In an even more specific embodiment of the device according to the invention, the top surface of the evacuation duct extends in the extension of the membrane. This embodiment is in particular in the context of the flattened, preferably substantially elliptical, evacuation duct mentioned above. The set fits perfectly with the space constraint imposed by the helmet.
En outre, le dispositif de fixation du masque au casque est tel qu'il permet une libération et une fixation extrêmement aisées d'un casque à l'autre et permet l'usage dans le domaine des motoneiges.In addition, the device for attaching the mask to the helmet is such that it allows extremely easy release and attachment from one helmet to another and allows use in the field of snowmobiles.
Le problème existant ici réside dans le fait qu'il faut tenir compte de contraintes constructives imposées du point de vue du design et de l'aérodynamisme qui est spécifique aux casques pour motocyclistes, dans lequel l'aspect ventilation n'occupait pas une place prioritaire.The problem existing here lies in the fact that it is necessary to take account of constructive constraints imposed from the point of view of design and aerodynamics which is specific to helmets for motorcyclists, in which the ventilation aspect did not occupy a priority place. .
Ce problème a été résolu suivant l'invention en adaptant les contraintes précitées et en les intégrant en partant de l'exigence posée pour le casque pour moto dans une perspective plus large de casque pour le motoneige précité.This problem was solved according to the invention by adapting the above constraints and integrating them starting from the requirement for the helmet for a motorcycle in a broader perspective of helmet for the aforementioned snowmobile.
Suivant une particularité additionnelle du dispositif selon l'invention, il est prévu une attache unique pour l'application du masque, dans laquelle deux sangles latérales de serrage du masque permettent un réglage manuel de la pression du masque en application directe sur le visage. Le désolidarisation du masque ne peut s'opérer que d'un côté étant donné la présence d'une seule attache. Toutefois cela rend un préréglage obligatoire, ce qui en fait un dispositif plus sûr. En outre, la simplification des sangles permet un maniement et un réglage simplifiés pour l'usager moyen. Une autre particularité du système d'application dans le dispositif suivant l'invention réside dans le fait que l'accrochage du masque est facial au lieu d'être latéral. L'attache unique proposée suivant l'invention offre l'avantage que lorsque l'usager détache le masque, celui-ci doit rester solidaire du casque de sorte qu'une manipulation malencontreuse de la boucle de fermeture ne risque pas de faire tomber le masque. Il en résulte que le dispositif à attache unique avec maintien du masque sur le casque rend impossible toute manipulation malencontreuse d'ouverture involontaire qui aurait pour conséquence la chute du masque.According to an additional feature of the device according to the invention, there is provided a single attachment for applying the mask, in which two lateral straps for tightening the mask allow manual adjustment of the pressure of the mask in direct application to the face. The separation of the mask can only take place on one side given the presence of a single fastener. However, this makes presetting mandatory, which makes it a safer device. In addition, the simplification of the straps allows simplified handling and adjustment for the average user. Another particularity of the application system in the device according to the invention lies in the fact that the attachment of the mask is facial instead of being lateral. The single attachment proposed according to the invention offers the advantage that when the user detaches the mask, the mask must remain attached to the helmet so that inadvertent manipulation of the closure loop does not risk causing the mask to fall. . As a result, the device with a single attachment with the mask held on the helmet makes any inadvertent unintentional opening manipulation impossible, which would result in the mask falling.
Par ailleurs, l'absence totale d'attaches métalliques dans le dispositif de fixation du masque permet d'éliminer tout risque de blessure dû à ces moyens de fixation. C'est ainsi que l'intérieur du masque est parfaitement lisse et ne présente aucune proéminence qui soit de nature à blesser l'utilisateur offrant en plus l'avantage du confort d'utilisation.Furthermore, the total absence of metal fasteners in the mask fixing device eliminates any risk of injury due to these fixing means. Thus the interior of the mask is perfectly smooth and has no prominence which is likely to injure the user, further offering the advantage of comfort of use.
Grâce à l'absence d'éléments de fixation notamment métalliques, on dispose dans le cas présent d'un choix de matériaux très étendu pour les éléments constituants du masque.Thanks to the absence of fixing elements, in particular metallic, there is in the present case a very wide choice of materials for the constituent elements of the mask.
A cet égard, dans un mode de réalisation particulièrement avantageux du dispositif selon l'invention, il est constitué d'une pièce monobloc avec une fixation extérieure souple, de préférence une fixation par contrainte de forme. Ainsi, la boucle est de type encliquetable.In this regard, in a particularly advantageous embodiment of the device according to the invention, it consists of a single piece with a flexible external attachment, preferably an attachment by form constraint. Thus, the loop is of the snap type.
En outre, un mode de réalisation avantageux du dispositif suivant l'invention comprend également un filtre qui a une fonction d'absorption.In addition, an advantageous embodiment of the device according to the invention also comprises a filter which has an absorption function.
La présente invention se rapporte également à un casque comprenant un dispositif précité, lesquels sont pourvus de moyens de fixation pour permettre la fixation de ce dernier au casque, de façon à permettre d'éviter la formation de buée et/ou de givre sur la visière. D'autres particularités et détails sont définis dans les sous- revendications annexées.The present invention also relates to a helmet comprising a said device, which are provided with fixing means to allow the fixing of the latter to the helmet, so as to prevent the formation of fogging and / or frost on the visor. . Other features and details are defined in the accompanying dependent claims.
D'autres avantages et propriétés résulteront de la description donnée ci-après d'un mode de réalisation exemplaire du dispositif pour casque suivant l'invention à l'aide des dessins annexés.Other advantages and properties will result from the description given below of an exemplary embodiment of the helmet device according to the invention using the attached drawings.

C'est essentiellement sur base de cette figure qu'est décrit le dispositif ci-après.Figure 2 shows the same evacuation device but in exploded view. It is essentially on the basis of this figure that the device described below is described.
Le masque 1 comprend deux éléments constitutifs dont un élément 7 dit membrane, qui est de préférence monobloc et souple. La membrane 7 ne présente aucune surface saillante intérieure, ce qui apparaît clairement de la figure 3c. Ainsi, la surface intérieure 28 du masque 1 est généralement lisse en ne présentant aucune proéminence, alliant confort et sécurité grâce à l'absence de tout élément blessant.The mask 1 comprises two constituent elements including an element 7 called a membrane, which is preferably one-piece and flexible. The membrane 7 has no internal projecting surface, which is clearly seen in FIG. 3c. Thus, the inner surface 28 of the mask 1 is generally smooth with no prominence, combining comfort and safety thanks to the absence of any injurious element.
Le masque présente une sortie unique 9 de type trompe orientée vers le bas, c'est-à-dire en conformité avec le sens de gravité lorsqu'il est mis en place sur le visage d'un utilisateur, de sorte que l'air expiré par le porteur du casque soit évacué de la façon la plus naturelle. Le but du conduit d'évacuation est de contrer la formation de buée sur la visière du casque de façon à assurer une parfaite visibilité pour le porteur du casque.The mask has a single outlet 9 of the downward-facing proboscis type, that is to say in accordance with the direction of gravity when it is placed on the face of a user, so that the air expired by the wearer of the helmet is evacuated in the most natural way. The purpose of the exhaust duct is to counter the formation of fogging on the helmet visor so as to ensure perfect visibility for the helmet wearer.
Le conduit d'évacuation 9 se rattache à la membrane 7, de préférence en y étant intégré comme illustré sur la figure, suivant une réalisation monobloc. Ceci assure une étanchéité totale de l'ensemble permettant d'éviter toute fuite et d'écarter ainsi tout risque de formation de buée.The discharge duct 9 is connected to the membrane 7, preferably by being integrated therein as illustrated in the figure, according to a one-piece embodiment. This ensures total tightness of the assembly, thereby preventing any leakage and thus eliminating any risk of fogging.
Le canal d'évacuation 9 présente une section transversale aux dimensions sensiblement constantes et une surface d'enveloppe parfaitement lisse. Ainsi, lorsque le porteur du casque expire, aucune condensation ne peut se former dans des zones de surface non lisses ou anfractuosités quelconques, lesquelles sont inexistantes ici. En outre, grâce à l'orientation vers le bas du canal d'évacuation 9, l'eau contenue dans l'air exhalé pouvant se déposer sur les parois intérieures du canal d'évacuation aura naturellement tendance à s'évacuer vers le bas par l'effet de gravité.The discharge channel 9 has a cross section with substantially constant dimensions and a perfectly smooth envelope surface. Thus, when the wearer of the helmet expires, no condensation can form in non-smooth surface areas or any crevices, which are nonexistent here. In addition, thanks to the downward orientation of the exhaust channel 9, the water contained in the exhaled air which can be deposited on the interior walls of the exhaust channel will naturally tend to evacuate downwards. the effect of gravity.
De plus, le profil du conduit d'évacuation 9 est de préférence incurvé comme illustré sur la figure 3b, de telle sorte qu'à la sortie 12 du conduit 9 les effluents exhalés suivent une trajectoire pratiquement en aplomb. Cela minimise le risque de refoulement de ceux-ci vers la visière 23 du casque.In addition, the profile of the discharge duct 9 is preferably curved as illustrated in FIG. 3b, so that at the outlet 12 of the duct 9 the exhaled effluents follow a substantially vertical trajectory. This minimizes the risk of them being pushed back towards the visor 23 of the helmet.
La section transversale du conduit d'évacuation 9 présente avantageusement une allure plutôt aplatie, de préférence elliptique, ainsi qu'il apparaît des figures 3b au regard des figures 3a et 3c. Ainsi qu'il ressort des figures précitées avec la figure 5, l'axe elliptique inférieur est agencé en profondeur car c'est là que la contrainte d'espace est la plus critique pour le casque, tandis que l'axe supérieur est agencé dans le sens de la largeur.The cross section of the exhaust duct 9 advantageously has a rather flat, preferably elliptical, shape. as appears from FIGS. 3b with regard to FIGS. 3a and 3c. As is apparent from the aforementioned figures with FIG. 5, the lower elliptical axis is arranged in depth because this is where the space constraint is most critical for the helmet, while the upper axis is arranged in the sense of width.
En outre, le masque 1 comprend un capot 6 qui est réalisé en un matériau semi-rigide. Le capot semi-rigide 6 permet le maintien de l'ensemble sur la tête du porteur du casque auquel le masque est fixé. Le capot 6 sert également d'élément récepteur de la pression exercée par le casque et coopère directement avec le système de fixation du masque au casque.In addition, the mask 1 comprises a cover 6 which is made of a semi-rigid material. The semi-rigid cover 6 allows the assembly to be held on the head of the wearer of the helmet to which the mask is attached. The cover 6 also serves as an element for receiving the pressure exerted by the helmet and cooperates directly with the system for attaching the mask to the helmet.
La fixation du capot à la membrane peut se faire avantageusement par contrainte de forme, par exemple par encliquetage. A cet effet, la figure 3b fait apparaître sur la membrane 7 deux éléments en saillie extérieure 15, qui s'engagent dans deux ouvertures 16 correspondants prévus dans le capot 6. Alternativement, les éléments de fixation 2 peuvent également être constitués par des moyens de type vis-écroux ou analogues, tels qu'illustrés sur la figure 2, lesquels coopèrent également avec les ouvertures 16.The fixing of the cover to the membrane can advantageously be done by form constraint, for example by snap-fastening. To this end, Figure 3b shows on the membrane 7 two external projecting elements 15, which engage in two corresponding openings 16 provided in the cover 6. Alternatively, the fastening elements 2 can also be constituted by means of screw-nut type or the like, as illustrated in FIG. 2, which also cooperate with the openings 16.
La forme du masque 1 est parfaitement adaptée à la morphologie du visage humain tout en permettant une visibilité maximale pour l'utilisateur, c'est-à-dire le porteur du casque, comme illustré sur la figure 5. En effet, le dispositif d'évacuation s'applique à partir du nez en s'étendant vers le bas de façon à recouvrir partiellement les joues et entièrement la bouche, de telle sorte que les ouvertures d'exhalation, le nez et la bouche, se trouvent à proximité directe de l'entrée 24 du conduit d'évacuation 9. Cette proximité immédiate permet de réduire au maximum le trajet des effluents exhalés, ce qui réduit aussi au maximum le risque de condensation sur les parois, contribuant ainsi à optimiser l'évacuation des effluents exhalés.The shape of the mask 1 is perfectly adapted to the morphology of the human face while allowing maximum visibility for the user, that is to say the wearer of the helmet, as illustrated in FIG. 5. In fact, the device of the evacuation is applied from the nose, extending downwards so as to partially cover the cheeks and entirely the mouth, so that the exhalation openings, the nose and the mouth, are in the immediate vicinity of the inlet 24 of the discharge conduit 9. This immediate proximity makes it possible to minimize the path of the exhaled effluents, which also minimizes the risk of condensation on the walls, thus helping to optimize the evacuation of the exhaled effluents.
Avantageusement, la surface extérieure du masque présente un léger rebord 19, de façon à délimiter une zone de réception 18 pour le capot 6. La hauteur du rebord 19 correspond sensiblement à l'épaisseur du capot 6. Ceci permet d'emboîter parfaitement le capot 6 sur la membrane 7 au sein du rebord précité 19 sur pratiquement tout son pourtour hormis à la base 24 du conduit d'évacuation 9, zone dans laquelle le capot 6 s'emboîte directement avec celle-ci 24. A cet effet, le capot 6 présente un évidement 25 permettant de coopérer intimement avec la base du conduit d'évacuation 9 lors de l'emboîtement. Ainsi, le capot 6 est réalisé principalement sous la forme de deux ailes 26, 26' mutuellement séparées par ledit évidement 25 et se rejoignant en une zone médiane. Cet agencement permet une disposition dans laquelle le capot 6 est pratiquement à fleur avec la membrane 7.Advantageously, the outer surface of the mask has a slight rim 19, so as to delimit a reception area 18 for the cover 6. The height of the rim 19 corresponds substantially to the thickness of the cover 6. This makes it possible to fit the cover 6 perfectly onto the membrane 7 within the aforementioned rim 19 over practically all of its periphery except at the base 24 of the conduit d 'evacuation 9, zone in which the cover 6 fits directly with the latter 24. For this purpose, the cover 6 has a recess 25 making it possible to cooperate intimately with the base of the evacuation duct 9 during the fitting. Thus, the cover 6 is produced mainly in the form of two wings 26, 26 'mutually separated by said recess 25 and joining in a central zone. This arrangement allows an arrangement in which the cover 6 is practically flush with the membrane 7.
L'application du masque 1 se fait par une attache unique 10, deux sangles 4 latérales de serrage du masque permettant de régler manuellement la pression du masque directement sur le visage. L'attache unique peut consister en une boucle 10, la fixation étant sensiblement centrale. La boucle 10 coopère avec une sangle de réglage 4. La sangle 4 est élastique. Le réglage de la sangle est assuré de façon connue au moyen de passants de réglage 3.The application of the mask 1 is done by a single attachment 10, two lateral straps 4 for tightening the mask making it possible to manually adjust the pressure of the mask directly on the face. The single attachment may consist of a loop 10, the attachment being substantially central. The loop 10 cooperates with an adjustment strap 4. The strap 4 is elastic. The adjustment of the strap is carried out in a known manner by means of adjustment loops 3.
Dans la zone médiane précitée du capot sont prévues les deux ouvertures de fixation précités 16, lesquels entourent la patte d'accrochage 27 de la boucle 10. La coopération se fait par contrainte de forme, de préférence par encliquetage. Les ailes précitées 26, 26' sont avantageusement pourvues d'une pluralité d'orifices 29.In the aforementioned central region of the cover, the two aforementioned fixing openings 16 are provided, which surround the latching tab 27 of the loop 10. The cooperation takes place by form constraint, preferably by snap-fastening. The aforementioned wings 26, 26 ′ are advantageously provided with a plurality of orifices 29.
De plus, le masque peut avantageusement comprendre un filtre 8 ayant pour fonction d'absorber au maximum l'humidité et les impuretés contenues dans l'air exhalé par le porteur du casque. L'agencement du filtre 8 est illustré sur la figure 2 en amont de la membrane 7.In addition, the mask can advantageously comprise a filter 8 having the function of absorbing as much as possible the humidity and the impurities contained in the air exhaled by the wearer of the helmet. The arrangement of the filter 8 is illustrated in FIG. 2 upstream of the membrane 7.
La figure 4 illustre un renfort 30 à insérer dans le conduit d'évacuation 9 du masque 1 afin de rigidifier celui-ci 1 . Il est entendu que la présente demande s'étend également à un casque 20 comprenant un masque 1 du type décrit ci-dessus fixé au casque 20 par des moyens de fixation 5, constitué par exemple par des entailles aux contours renforcés coopérant avec des ergots agencés sur le casque comme illustré sur la figure 5.FIG. 4 illustrates a reinforcement 30 to be inserted into the evacuation duct 9 of the mask 1 in order to stiffen the latter 1. It is understood that the present application also extends to a helmet 20 comprising a mask 1 of the type described above fixed to the helmet 20 by fixing means 5, constituted for example by notches with reinforced contours cooperating with lugs arranged on the helmet as illustrated in figure 5.
La figure 5 illustre plus particulièrement une patte de fixation latérale 21 enclipsée entre la calotte et le coussinet du casque au niveau des joues de l'utilisateur. FIG. 5 more particularly illustrates a lateral fixing tab 21 clipped between the cap and the helmet pad at the level of the user's cheeks.
