Description

Domaine technique de l'inventionTechnical field of the invention

L'invention est relative à un casque de protection comportant un serre-nuque.The invention relates to a protective helmet comprising a neckband.

État de la techniqueState of the art

Les casques de protection sont par exemple utilisés en alpinisme ou en escalade pour servir de protection en cas de chutes de pierres ou de choc à la tête. Ils font donc partie du matériel indispensable pour les grimpeurs et les alpinistes.Helmets are used for example in mountaineering or climbing to serve as protection in case of falling rocks or shock to the head. They are therefore part of the essential equipment for climbers and mountaineers.

Etant donné que le matériel d'alpinisme ou d'escalade est encombrant, il y a tout intérêt à ce qu'il soit rangé de façon la plus compacte possible. Cela est particulièrement vrai pour une utilisation des casques de protection en collectivité, qui deviennent difficilement transportables s'ils ne sont pas empilés les uns sur les autres.Since mountaineering or climbing equipment is cumbersome, it is best to keep it as compact as possible. This is particularly true for the use of protective helmets in the community, which become difficult to transport if they are not stacked on top of each other.

En pratique, la superposition des casques utilisés en collectivité n'est pas chose aisée car ceux-ci comprennent des serres-nuque qui dépassent bien souvent des calottes des casques de protection et empêchent leur empilement correct.In practice, the superposition of helmets used in community is not easy because they include neckrests that often exceed the caps of the protective helmets and prevent their correct stacking.

Cela est par exemple le cas pour le casque Elios (première génération, serre nuque fixe) commercialisé sous la marque Petzl par la demanderesse. La première génération du casque Elios était dotée d'un serre-nuque fixe et non réglable, empêchant tout empilement des casques les uns sur les autres. Dans la deuxième génération, le casque Elios doté d'un serre-nuque réglable, peut s'empiler à condition de diminuer sa taille au minimum. Toutefois l'empilement est réalisé au détriment des réglages effectués, ce qui engendre soit une perte de temps pour le moniteur qui doit régler le matériel à chaque utilisation, soit une mauvaise utilisation du casque au risque de mal protéger l'utilisateur en cas de choc.This is for example the case for the Elios helmet (first generation, fixed hothouse) marketed under the brand Petzl by the plaintiff. The first generation of the Elios helmet had a fixed and non-fixed neckband adjustable, preventing stacking of the helmets on each other. In the second generation, the Elios helmet with an adjustable neckband can be stacked as long as it is kept to a minimum. However, stacking is done to the detriment of the adjustments made, which causes either a loss of time for the monitor who has to adjust the equipment for each use, or a wrong use of the helmet at the risk of poorly protect the user in case of shock .

Objet de l'inventionObject of the invention

Un objet de l'invention consiste à proposer un casque de protection configuré pour permettre un rangement facilité et sûr avec d'autres casques de protection.An object of the invention is to provide a protective helmet configured to allow easy and secure storage with other protective helmets.

A cet effet, le casque de protection comporte une calotte dotée d'une partie frontale et d'une partie occipitale comprenant une partie occipitale interne, un serre-nuque ayant une face interne destinée à être en contact avec la tête d'un utilisateur, et des moyens d'articulation configurés pour permettre le passage du serre-nuque d'une position d'utilisation à une position de rangement du casque de protection. En position de rangement, le serre-nuque est rabattu dans la partie occipitale de la calotte de sorte que la face interne du serre-nuque soit en vis-à-vis de la partie occipitale interne de la calotte.For this purpose, the protective helmet comprises a cap having a front portion and an occipital portion comprising an internal occipital portion, a neckband having an internal face intended to be in contact with the head of a user, and hinge means configured to allow passage of the neckband from a use position to a storage position of the protective helmet. In storage position, the neck band is folded in the occipital portion of the cap so that the inner face of the neck band is vis-à-vis the occipital portion of the inner cap.

Par ailleurs, le serre-nuque peut être réalisé dans un matériau déformable tout en étant apte à retrouver sa forme initiale.Furthermore, the neckband can be made of a deformable material while being able to regain its original shape.

Selon un aspect de l'invention, la position d'utilisation et la position de rangement peuvent être toutes les deux des positions stables du serre-nuque, l'effort à fournir pour faire passer le serre-nuque d'une position stable à l'autre pouvant passer par un maximum.According to one aspect of the invention, the use position and the storage position can both be stable positions of the neckband, the effort required to move the neckband from one stable position to another that can go through a maximum.

Le casque de protection peut également comprendre des moyens de blocage configurés pour maintenir le serre-nuque en position de rangement.The protective helmet may also include locking means configured to maintain the neckband in the storage position.

Selon un mode de réalisation, les moyens d'articulation peuvent être aptes à contraindre le serre-nuque à se positionner de manière stable uniquement dans la position d'utilisation et dans la position de rangement du casque de protection.According to one embodiment, the hinge means can be adapted to constrain the neckband to position itself stably only in the use position and in the storage position of the protective helmet.

Par ailleurs, les moyens d'articulation peuvent comporter au moins une charnière dont une première partie est reliée au serre-nuque. L'une au moins des charnières peut comporter une deuxième partie fixée sur la calotte ou sur un tour de tête, la deuxième partie étant montée en liaison pivot avec la première partie.Furthermore, the hinge means may comprise at least one hinge whose first part is connected to the neck-band. At least one of the hinges may comprise a second part fixed on the cap or on a headband, the second part being mounted in pivot connection with the first part.

Lorsque les moyens d'articulation comportent deux charnières, ces dernières peuvent être pourvues de deuxième partie en liaison pivot avec les premières parties, les axes des deux liaisons pivot étant concourants.When the hinge means comprise two hinges, the latter can be provided with a second part in pivot connection with the first parts, the axes of the two pivot links being concurrent.

Selon un aspect de l'invention, le casque de protection comporte des moyens de réglage de la hauteur du serre-nuque faisant saillie à l'extérieur de la calotte. Le casque peut également comporter des moyens de réglage du serre-nuque faisant saillie à l'extérieur de la calotte de manière à l'adapter au tour de tête de l'utilisateur.According to one aspect of the invention, the protective helmet comprises means for adjusting the height of the neckband protruding outside the cap. The helmet may also include means for adjusting the neckband protruding outside the cap so as to adapt to the head of the user.

Les moyens de réglage peuvent par exemple comprendre au moins une sangle élastique, ou une sangle et un dispositif de réglage en longueur de la sangle.The adjustment means may for example comprise at least one elastic strap, or a strap and a device for adjusting the length of the strap.

L'invention concerne également un procédé de rangement d'au moins deux casques de protection tels que décrits ci-dessus, le procédé comportant les étapes suivantes :

  • placer le serre-nuque de l'un au moins des casques de protection dans la position de rangement,
  • empiler l'un au moins des casques de protection sur l'un au moins des autres casques de protection.
The invention also relates to a method of storing at least two protective helmets as described above, the method comprising the following steps:
  • place the neckband of at least one of the protective helmets in the storage position,
  • stack at least one of the protective helmets on at least one of the other protective helmets.

Description détailléedetailed description

Les figures 1 et 2 représentent un casque de protection 1 comportant une calotte 2 fabriquée dans un matériau empêchant de la replier sur elle-même. La calotte 2 peut être réalisée par exemple en polycarbonate ou ABS injecté ou en polystyrène ou en polypropylène expansé, ou en toute autre matière plastique, notamment en matière plastique injectée, thermoformée ou en mouse.The Figures 1 and 2 represent a protective helmet 1 having a cap 2 made of a material preventing it from folding on itself. The cap 2 may be made for example of injected polycarbonate or ABS or polystyrene or expanded polypropylene, or any other material plastic, in particular injected plastic, thermoformed or mouse.

La calotte 2 comporte une partie frontale située à l'avant, c'est-à-dire à proximité du front de l'utilisateur, et une partie occipitale située à l'arrière. La partie occipitale interne 2a est située au niveau de la nuque lorsque le casque 1 est utilisé.The cap 2 has a front portion located at the front, that is to say near the user's forehead, and an occipital portion located at the rear. The inner occipital portion 2a is located at the neck when the helmet 1 is used.

Le casque de protection 1 est préférentiellement équipé d'un serre-nuque 3, avantageusement réalisé dans un matériau déformable tout en étant apte à retrouver sa forme initiale, tel que du polyamide, du polyoxyméthylène ou du polyéthylène. Le serre-nuque 3 comporte une face interne 3a destinée à être en contact avec la tête d'un utilisateur, et une face externe 3b (cf. figures 1 et 2).The protective helmet 1 is preferably equipped with a neckband 3, advantageously made of a deformable material while being able to recover its original shape, such as polyamide, polyoxymethylene or polyethylene. The neckband 3 has an inner face 3a intended to be in contact with the head of a user, and an outer face 3b (cf. Figures 1 and 2 ).

Le casque de protection 1 peut également être doté d'un tour de tête 4. Le serre-nuque 3 et le tour de tête 4 permettent un meilleur réglage de la position du casque de protection 1 en prenant appui sur la nuque d'un utilisateur. On peut toutefois envisager que le tour de tête 4 ne soit pas présent.The protective helmet 1 may also be provided with a headband 4. The neckband 3 and the headband 4 allow a better adjustment of the position of the protective helmet 1 by pressing on the neck of a user . However, we can consider that the headband 4 is not present.

Le casque de protection 1 est avantageusement doté de sangles jugulaires 5 permettant de fixer le casque 1 sur la tête de l'utilisateur. Les sangles jugulaires 5 sont fixées à la calotte 2 ou au tour de tête 4 et traversent avantageusement le serre-nuque 3. Le rôle des sangles jugulaires 5 est d'assurer le contact entre la nuque de l'utilisateur et la face interne du serre-nuque 3a lors de l'utilisation du casque de protection 1.The protective helmet 1 is advantageously provided with jugular straps 5 for fixing the helmet 1 on the head of the user. The jugular straps 5 are fixed to the cap 2 or the head 4 and advantageously pass through the neckband 3. The role of the jugular straps 5 is to ensure the contact between the nape of the user and the inner face of the greenhouse -nuque 3a when using the protective helmet 1.

Le casque de protection 1 comprend avantageusement une coque de rembourrage en mousse (non représentée), logée à l'intérieur de la calotte 2 et directement en contact avec la tête de l'utilisateur. La calotte 2 peut également être dotée de trous de ventilation (non représentés) destinés à améliorer le confort de l'utilisateur.The protective helmet 1 advantageously comprises a foam padding shell (not shown), housed inside the cap 2 and directly in contact with the head of the user. The cap 2 can also be provided with ventilation holes (not shown) to improve the comfort of the user.

Le serre-nuque 3 est avantageusement mobile par rapport à la calotte 2 et par rapport au tour de tête 4, et comporte deux positions avantageusement stables : une première position correspondant à une position d'utilisation du casque de protection 1 (cf. figure 1), et une deuxième position correspondant à une position de rangement du casque de protection 1 (cf. figure 2).The neckband 3 is advantageously movable relative to the cap 2 and with respect to the headband 4, and has two advantageously stable positions: a first position corresponding to a position of use of the protective helmet 1 (cf. figure 1 ), and a second position corresponding to a storage position of the protective helmet 1 (cf. figure 2 ).

Dans la première position, le serre-nuque 3 fait saillie hors du volume délimité par la calotte 2. En revanche dans la deuxième position, le serre-nuque 3 est replié à l'intérieur du volume délimité par la calotte 2, et plus précisément dans la partie occipitale de la calotte 2, de sorte que la face interne 3a du serre-nuque 3 soit en vis-à-vis de la partie occipitale interne 2a de la calotte 2.In the first position, the neckband 3 protrudes out of the volume delimited by the cap 2. On the other hand in the second position, the neckband 3 is folded inside the volume delimited by the cap 2, and more precisely in the occipital portion of the cap 2, so that the inner face 3a of the neckband 3 is vis-à-vis the inner occipital portion 2a of the cap 2.

Pour que le serre-nuque 3 puisse changer de position, le casque de protection 1 est avantageusement doté de moyens d'articulation 6. Ces moyens d'articulation 6 peuvent avantageusement comporter des liaisons pivots telles que des charnières.So that the neckband 3 can change position, the protective helmet 1 is advantageously provided with hinge means 6. These hinge means 6 may advantageously comprise pivot links such as hinges.

Les charnières peuvent être réalisées en une seule partie pouvant se plier selon un axe comportant moins de matière que le reste de la charnière, de manière analogue à un bouchon à clapet.The hinges can be made in one piece that can bend along an axis with less material than the rest of the hinge, similarly to a plug valve.

Les charnières peuvent également être réalisées à l'aide de plusieurs pièces connectées entre elles au moyen d'une tige de liaison. La charnière est alors analogue à un goujon de porte.The hinges can also be made using several parts connected to each other by means of a connecting rod. The hinge is then analogous to a door stud.

Les moyens d'articulation 6 sont aptes à contraindre le serre-nuque 3 à se positionner de manière stable dans la position d'utilisation ou dans la position de rangement. Selon un mode de réalisation particulier, ces deux positions peuvent être les deux seules positions stables dans lesquelles le serre-nuque 3 peut se placer. Ces deux positions stables sont alors séparées par des positions instables qui vont placer le serre-nuque 3 soit dans la position de rangement, soit dans la position d'utilisation.The hinge means 6 are able to force the neckband 3 to position itself stably in the position of use or in the position storage. According to a particular embodiment, these two positions may be the only two stable positions in which the neckband 3 can be placed. These two stable positions are then separated by unstable positions that will place the neckband 3 is in the storage position or in the use position.

Le casque de protection 1 peut par exemple comporter deux articulations 6. Dans le mode de réalisation illustré sur les figures annexées, les moyens d'articulation 6 sont avantageusement des charnières comportant une première partie reliée à l'extrémité du serre-nuque 3, et une deuxième partie reliée par exemple au tour de tête 4. De manière alternative, les charnières pourraient comprendre une deuxième partie fixée sur la calotte 2. Il est également possible de combiner ces modes de réalisation.The protective helmet 1 may for example comprise two joints 6. In the embodiment illustrated in the accompanying figures, the hinge means 6 are advantageously hinges having a first portion connected to the end of the neckband 3, and a second part connected for example to the headband 4. Alternatively, the hinges could include a second portion fixed on the cap 2. It is also possible to combine these embodiments.

Les première et deuxième parties de chaque charnière des moyens d'articulation 6 sont avantageusement montées en liaison pivot l'une par rapport à l'autre.The first and second parts of each hinge of the hinge means 6 are advantageously mounted in pivot connection with respect to one another.

Lorsque les moyens d'articulation 6 comportent deux charnières, les axes des liaisons pivot sont avantageusement concourants. De cette façon, par déformation élastique du serre-nuque 3, ce dernier peut passer de la position d'utilisation à la position de rangement. Ces deux positions sont alors les deux seules positions stables du serre-nuque 3.When the hinge means 6 comprise two hinges, the axes of the pivot links are advantageously concurrent. In this way, by elastic deformation of the neckband 3, the latter can move from the use position to the storage position. These two positions are then the only two stable positions of the neckband 3.

Selon la configuration employée, une contrainte en compression ou un contrainte en traction est appliquée sur le serre-nuque 3 pour basculer d'une position à l'autre.Depending on the configuration employed, a compressive stress or a tensile stress is applied to the neckband 3 to switch from one position to another.

Pour pouvoir passer de la première position à la deuxième position, et inversement, l'effort à fournir passe par un maximum. L'effort dépend principalement du type de matériau utilisé pour réaliser le serre-nuque 3 et de la position des deux charnières relativement à la calotte 2 et/ou au tour de tête 4 selon l'endroit où elles sont fixées.To be able to pass from the first position to the second position, and conversely, the effort to be provided passes through a maximum. The effort depends mainly on the type of material used to make the neckband 3 and the position of the two hinges relative to the cap 2 and / or the head 4 according to where they are fixed.

En effet, plus la rigidité du matériau du serre-nuque 3 est élevée, plus il est difficile de le faire passer de la première position à la deuxième position. En ce qui concerne la position des charnières, deux facteurs sont à prendre en compte : la distance qui les sépare et l'angle formé par les axes des liaison pivot. Ainsi, il est d'autant plus difficile de faire passer le serre-nuque 3 d'une position à l'autre que les charnières sont placées l'une près de l'autre et que l'angle entre les axes est petit.Indeed, the higher the rigidity of the material of the neckband 3, the more difficult it is to move it from the first position to the second position. As regards the position of the hinges, two factors must be taken into account: the distance between them and the angle formed by the axes of the pivot connections. Thus, it is all the more difficult to pass the neckband 3 from one position to another that the hinges are placed close to each other and that the angle between the axes is small.

Le serre-nuque 3 comporte donc un point dur qui est fonction de la forme, des dimensions et du type de matériau utilisé.The neckband 3 thus has a hard point which is a function of the shape, the dimensions and the type of material used.

Lorsqu'il n'existe pas de position stable intrinsèque au serre-nuque 3, il peut être envisagé d'utiliser des moyens de blocage (non représentés) du serre-nuque 3 en position de rangement. Les moyens de blocage peuvent par exemple être des aimants, des clips, des velcros, etc. Les moyens de blocage peuvent également être utilisés à titre de maintien supplémentaire lorsque la position de rangement est une position stable du serre-nuque 3.When there is no intrinsic stable position to the neckband 3, it may be envisaged to use locking means (not shown) of the neckband 3 in the storage position. The locking means may for example be magnets, clips, velcro, etc. The locking means can also be used as additional support when the storage position is a stable position of the neckband 3.

Comme illustré sur les figures 3a et 3b, la forme de la tête peut différer selon l'âge et la taille de l'utilisateur. Il peut donc être par ailleurs avantageux de régler la hauteur du serre-nuque 3 faisant saillie à l'extérieur de la calotte 2 du casque de protection 1.As illustrated on Figures 3a and 3b , the shape of the head may differ depending on the age and size of the user. It may therefore be advantageous to adjust the height of the neckband 3 protruding outside the cap 2 of the protective helmet 1.

A cet effet, un mode de réalisation avantageux du casque de protection 1 peut comprendre des moyens de réglage configurés pour adapter la position ou la taille du serre-nuque 3.For this purpose, an advantageous embodiment of the protective helmet 1 may comprise adjustment means configured to adapt the position or the size of the neckband 3.

Par exemple, le serre-nuque 3 peut être formé en deux parties connectées par des moyens de réglage tels qu'une crémaillère. L'une des parties comprend des crans séparés par une fente, tandis que l'autre partie comprend un plot apte à se déplacer à l'intérieur de la fente. Le mouvement du plot dans la fente permet alors de rallonger ou raccourcir la longueur du serre-nuque 3.For example, the neckband 3 may be formed in two parts connected by adjustment means such as a rack. One of the parts comprises notches separated by a slot, while the other part comprises a pad adapted to move inside the slot. The movement of the stud in the slot then makes it possible to lengthen or shorten the length of the neckband 3.

De manière alternative, le serre-nuque 3 peut comprendre deux parties connectées par une sangle élastique. Pour cela, l'une des parties possède une sangle élastique terminée par un plot à une extrémité, et l'autre brin possède une série de trous à l'intérieur desquels le plot peut être inséré.Alternatively, the neckband 3 may comprise two parts connected by an elastic strap. For this, one of the parts has an elastic strap terminated by a stud at one end, and the other strand has a series of holes inside which the stud can be inserted.

Dans ces deux alternatives de réalisation, les deux parties du serre-nuque 3 se chevauchent plus ou moins, mais ils ne sont jamais distants, sans quoi l'efficacité du casque de protection 1 en cas de choc serait réduite.In these two alternative embodiments, the two parts of the neckband 3 overlap more or less, but they are never distant, otherwise the effectiveness of the protective helmet 1 in case of shock would be reduced.

Selon une alternative de réalisation, le serre-nuque 3 peut être formé en une seule partie connectée aux deux extrémités du tour de tête 4, l'une au moins des deux extrémités du tour de tête 4 étant dotée des moyens de réglage. Les moyens de réglage sont alors configurés pour faire coulisser l'une au moins des extrémités du serre-nuque 3 à l'intérieur du casque de protection 1, afin que la portion du serre-nuque 3 faisant saillie soit moins haute. Dans ce cas, l'une au moins des articulations 6 peut être positionnée sur le serre-nuque 3.According to an alternative embodiment, the neckband 3 may be formed in a single portion connected to both ends of the headband 4, at least one of the two ends of the headband 4 being provided with adjustment means. The adjustment means are then configured to slide at least one of the ends of the neckband 3 inside the protective helmet 1, so that the portion of the neckband 3 protruding is lower. In this case, at least one of the joints 6 can be positioned on the neckband 3.

Dans les casques de protection de l'art antérieur, le serre-nuque 3 est un frein à l'empilement correct des casques de protection 1 lorsque l'on maintien le serre-nuque 3 dans une position donnée. Pour empiler les casques de protection 1, il faut augmenter au maximum le diamètre global du serre-nuque 3 et donc enlever les réglages effectués par les utilisateurs. De plus cet empilement est moins stable et peut endommager le serre-nuque 3.In the protective helmets of the prior art, the neckband 3 is a brake on the correct stacking of the protective helmets 1 when the neckband 3 is held in a given position. To stack the helmets 1, it is necessary to increase to the maximum the overall diameter of the neckband 3 and thus to remove the adjustments made by the users. In addition this stack is less stable and can damage the neckband 3.

Ici, il n'est pas nécessaire d'enlever les réglages effectués lors de l'utilisation pour pouvoir ranger des casques 1 sans risque de détérioration. Il suffit de faire passer le serre-nuque 3 de la position d'utilisation à la position de rangement à l'aide des moyens articulations 6.Here, it is not necessary to remove the settings made during use to be able to store helmets 1 without risk of damage. It suffices to pass the neckband 3 from the use position to the storage position by means of the hinge means 6.

Dans le cadre d'une utilisation individuelle, l'utilisateur est assuré des qualités de son casque de protection 1 et n'a plus besoin de l'ajuster à chaque nouvelle utilisation.In the context of an individual use, the user is assured of the qualities of his protective helmet 1 and no longer needs to adjust it for each new use.

Pour une utilisation en collectivité, le moniteur peut effectuer les réglages des casques de protection 1 une fois pour toute afin de contraindre les utilisateurs à bien positionner le serre-nuque 3. Il peut également empiler les casques très facilement en plaçant chaque serre-nuque 3 en position de rangement.For use in community, the monitor can make the settings of the helmets 1 once and for all to force users to position the neckband 3. It can also stack the helmets very easily by placing each neckband 3 in storage position.

L'invention ne se limite pas aux caractéristiques qui viennent d'être mentionnées. L'homme du métier peut, sans sortir du cadre de l'invention, ajuster la position et le nombre d'articulations 6 afin de l'adapter à ses besoins.The invention is not limited to the features just mentioned. The person skilled in the art can, without departing from the scope of the invention, adjust the position and the number of joints 6 in order to adapt it to his needs.
