L'ajustement de ce dernier s'effectue au moyen d'un seul point de réglage localisé à l'arrière du casque au niveau de la nuque. Le dispositif de réglage comporte des crémaillères agencées aux deux extrémités arrières rectilignes du tour de tête, et coopérant avec un organe de commande rotatif lequel est placé dans la zone médiane.The ELIOS helmet marketed under the brand PETZL by the plaintiff, refers to a helmet having an injected polycarbonate shell shock resistant, an inner shell expanded polypropylene foam, a chinstrap, and a headband. The adjustment of the latter is made by means of a single set point located at the back of the helmet at the neck. The adjustment device comprises racks arranged at the two rectilinear rear ends of the headband, and cooperating with a rotary control member which is placed in the central zone.

Le casque ECRIN commercialisé sous la marque PETZL par la demanderesse et décrit dans le document EP 558427 , concerne un casque composé d'une calotte externe en polycarbonate, et d'un ensemble tour de tête et serre-nuque logé totalement à l'intérieur de la calotte. Le réglage du casque s'effectue grâce à deux molettes internes qui engrènent avec des crans de crémaillères prévues dans le tour de tête et le serre-nuque. Les molettes dépassent partiellement sous le bord latéral de chaque côté de la calotte. L'une des molettes sert pour l'ajustement du tour de tête, et l'autre pour le serre-nuque.The ECRIN helmet marketed under the brand PETZL by the Applicant and described in the document EP 558427 , relates to a helmet consisting of an outer cap polycarbonate, and a set of headband and neckband housed completely inside the cap. The setting of the The helmet is made with two internal knobs that mesh with racks of racks provided in the headband and the neckband. The knobs protrude partially under the side edge of each side of the cap. One of the knobs is used for the adjustment of the headband, and the other for the neckband.

Dans les deux casques connus précités, on fait varier la longueur périphérique du serre-nuque pendant le réglage, étant donné que les crémaillères sont localisées directement sur le serre-nuque.In the two known known helmets, the peripheral length of the neckband is varied during adjustment, since the racks are located directly on the neckband.

Objet de l'inventionObject of the invention

L'objet de l'invention consiste à réaliser un casque de protection équipé d'un serre-nuque à réglage rapide et pratique.The object of the invention is to provide a protective helmet with a neckband quick and convenient adjustment.

Le dispositif selon l'invention est caractérisé en ce qu'au moins une extrémité du serre-nuque est reliée à la calotte par une liaison mécanique coulissante comportant des moyens d'indexage en position pilotés à partir d'un coulisseau déplaçable depuis l'extérieur dans une fente de la calotte.The device according to the invention is characterized in that at least one end of the neckband is connected to the cap by a sliding mechanical connection comprising indexing means in position controlled from a slide movable from the outside. in a slit of the cap.

Les moyens d'indexage sont solidaires de la paroi interne de la calotte, et peuvent venir directement de moulage avec la calotte.The indexing means are integral with the inner wall of the cap, and can come directly from the molding with the cap.

La longueur du serre-nuque reste constante durant le réglage, tandis qu'on fait varier son point d'attache grâce aux moyens d'indexage localisés sur la paroi interne de la calotte. Le réglage est ainsi facilité.The length of the neckband remains constant during adjustment, while its attachment point is varied thanks to the indexing means located on the inner wall of the cap. The setting is thus facilitated.

Selon un mode de réalisation préférentiel, les moyens d'indexage sont constitués par une crémaillère comportant deux séries de crans séparées par la fente de logement du coulisseau. Le coulisseau est équipé d'un bouton de déverrouillage doté d'une pièce d'accouplement portant des ergots coopérant par encliquetage avec la crémaillère par l'action d'un ressort de rappel. Le coulisseau porte deux jambes de guidage du bouton de déverrouillage lors de son déplacement entre les positions active et inactive.According to a preferred embodiment, the indexing means are constituted by a rack having two series of notches separated by the housing slot of the slider. The slide is equipped with an unlocking button with a coupling part carrying cooperating lugs by snapping with the rack by the action of a return spring. The slide carries two guide legs of the unlocking button as it moves between the active and inactive positions.

La fente de déplacement du coulisseau peut être rectiligne ou incurvée, et le serre-nuque peut avoir une forme quelconque.The slit of movement of the slider may be rectilinear or curved, and the neckband may have any shape.

Description d'un mode préférentiel de l'inventionDescription of a preferred embodiment of the invention

Sur les figures 1 et 10, un casque 15 comporte une calotte 16 externe de protection réalisée en polycarbonate injecté ou toute autre matière plastique notamment thermoformée ou en polystyrène expansé.On the figures 1 and 10 , a helmet 15 comprises an outer protective cap 16 made of injected polycarbonate or any other plastic material including thermoformed or expanded polystyrene.

La calotte 16 est équipée d'une pluralité d'orifices 17 de ventilation, d'une coque 18 de rembourrage en mousse logée à l'intérieur de la calotte 16 avec un tour de tête 19, et un serre-nuque 20. La sangle jugulaire est d'un type bien connu, et n'est pas représentée sur les dessins. Un tel casque est notamment adapté à la pratique de l'escalade, de l'alpinisme, et également pour les travaux en hauteur.The cap 16 is equipped with a plurality of ventilation orifices 17, a foam padding shell 18 housed inside the cap 16 with a headband 19, and a neckband 20. The strap jugular is of a well known type, and is not shown in the drawings. Such a helmet is particularly suitable for climbing, mountaineering, and also for work at height.

Le tour de tête 19 s'étend le long du bord avant à l'intérieur de la calotte 16, en étant relié par deux bras de liaison 21, 22 à des moyens d'attache 23 solidarisés à la paroi interne de la calotte 16. Le bord périphérique arrière de la calotte 16 se trouve à l'opposé du bord avant, et est doté d'un contour 24 incurvé en forme de U renversé. Dans l'exemple de la figure 1, le tour de tête 19 n'est pas réglable.The headband 19 extends along the front edge inside the cap 16, being connected by two connecting arms 21, 22 to fastening means 23 secured to the inner wall of the cap 16. The rear peripheral edge of the cap 16 is opposite the front edge, and is provided with an inverted U-shaped contour 24. In the example of the figure 1 , the headband 19 is not adjustable.

Le serre-nuque 20 est ajustable par des moyens de réglage 25 accessibles depuis l'extérieur sur les côtés latéraux opposés de la calotte 16.The neckband 20 is adjustable by means of adjustment 25 accessible from the outside on the opposite lateral sides of the cap 16.

Sur les figures 2 à 9 et 11, le serre-nuque 20 est constitué par une bande de plastique souple ou semi-rigide, conformée selon un profil en Oméga ayant deux extrémités EX1, EX2 opposées, et une partie intermédiaire 26, laquelle est décalée du contour 24 de la calotte 16 par un espace arrière. Chaque extrémité EX1, EX2 du serre-nuque 20 comporte un trou 27 circulaire dans lequel est engagé un plot de retenue 28 équipé d'une pluralité de picots 29 dirigés en direction d'une crémaillère 30 ménagée dans la paroi interne de la calotte 16.On the Figures 2 to 9 and 11 , the neckband 20 is constituted by a flexible or semi-rigid plastic strip, shaped according to an Omega profile having two ends EX1, EX2 opposite, and an intermediate portion 26, which is offset from the contour 24 of the cap 16 by a rear space. Each end EX1, EX2 of the neckband 20 comprises a circular hole 27 in which is engaged a retaining stud 28 equipped with a plurality of pins 29 directed towards a rack 30 formed in the inner wall of the cap 16.

La crémaillère 30 comporte deux séries de crans 30a, 30b parallèles séparées l'une de l'autre par une fente 31 longitudinale à l'intérieur de laquelle se déplace un coulisseau 32 après actionnement d'un bouton de déverrouillage 33. La crémaillère 30 vient directement de moulage avec la calotte 16, et le bouton de déverrouillage 33 traverse une ouverture 34 du coulisseau 32 en étant guidé dans des glissières 35 ménagées dans des jambes 36, 37 de guidage du coulisseau 32.The rack 30 comprises two series of notches 30a, 30b parallel separated from each other by a longitudinal slot 31 inside which moves a slide 32 after actuation of an unlocking button 33. The rack 30 comes directly molding with the cap 16, and the unlocking button 33 through an opening 34 of the slide 32 being guided in slides 35 formed in legs 36, 37 for guiding the slide 32.

Un ressort de rappel 38 du type à compression, est agencé entre un pion de centrage 39 du plot de retenue 28 et un trou 41 ménagé dans une pièce d'accouplement 40 solidaire du bouton de déverrouillage 33.A return spring 38 of the compression type is arranged between a centering pin 39 of the retaining pin 28 and a hole 41 formed in a coupling piece 40 integral with the unlocking button 33.

La pièce d'accouplement 40 porte des ergots 42 coopérant avec la crémaillère 30 par l'action de rappel du ressort 38 en position relâchée du bouton de déverrouillage 33.The coupling piece 40 carries lugs 42 cooperating with the rack 30 by the return action of the spring 38 in the released position of the unlocking button 33.

Une rondelle 43 auxiliaire (figure 2) est en plus intercalée entre la crémaillère 30 et l'extrémité correspondante EX1, EX2 du serre-nuque 20. La rondelle 43 comporte une paire de protubérances 44, 45 semi-circulaires diamétralement opposées le long de la périphérie interne, de manière à s'engager pour un réglage prédéterminé, entre deux crans successifs de chaque série de crans 30a, 30b de la crémaillère 30. Tout changement de réglage émet un clic sonore des protubérances 44, 45 suite au déplacement en translation du coulisseau 32.An auxiliary washer 43 ( figure 2 ) is further interposed between the rack 30 and the corresponding end EX1, EX2 of the neckband 20. The washer 43 has a pair of diametrically opposed semi-circular protuberances 44, 45 along the inner periphery, so that engage for a predetermined adjustment, between two successive notches of each series of notches 30a, 30b of the rack 30. Any change in setting emits an audible click of the protuberances 44, 45 following the translational movement of the slide 32.

Sur la figure 11, une vue développée du serre-nuque 20 de la figure 10 montre la forme en Oméga avec la partie intermédiaire 26 médiane assurant un passage sous le contour 24 de la calotte 16, ce qui est particulièrement pratique pour des utilisateurs ayant des coiffures à queues-de-cheval.On the figure 11 , a developed view of the neckband 20 of the figure 10 shows the Omega shape with the median intermediate portion 26 ensuring a passage under the contour 24 of the cap 16, which is particularly convenient for users having ponytail hairstyles.

La figure 12 montre un serre-nuque 120 avec une partie intermédiaire droite, et sans évidement en arc. Il convient bien entendu pour les personnes n'ayant pas de queues-de-cheval. Un tel serre-nuque 120 est également ajustable par les moyens de réglage 25 en translation des figures 2-9.The figure 12 shows a neckband 120 with a straight middle part, and without bow recess. It is of course for people without ponytails. Such neckband 120 is also adjustable by the translational adjustment means 25. Figures 2-9 .

Le réglage du serre-nuque 20 selon l'invention s'effectue de la manière suivante :

  • Avec ses deux mains, l'utilisateur appuie en même temps sur les deux boutons de déverrouillage 33 à l'encontre des ressorts de rappel 38. Les ergots 42 de la pièce d'accouplement 40 sortent de la crémaillère 30, ce qui libère les extrémités EX1, EX2 du serre-nuque 20. Il suffit ensuite de déplacer en translation les coulisseaux 32 dans les fentes 31 jusqu'au contact du serre-nuque 20 contre la nuque de l'utilisateur. Le relâchement des boutons de déverrouillage 33 ramène automatiquement les ergots 42 dans la crémaillère 30 correspondante, assurant le blocage du réglage dans la position choisie.
  • Au lieu d'avoir les deux extrémités EX1, EX2 réglables, il est également possible d'en avoir une fixe, et l'autre réglable.
  • Il est clair que la crémaillère 30 peut être remplacée par tout autre moyen d'indexage en position piloté à partir du coulisseau extérieur.
  • Le réglage est rapide, et est opéré depuis l'extérieur sur les côtés latéraux de la calotte 16. Aucune intervention n'est nécessaire à l'arrière du casque 15, quel que soit le type de serre-nuque selon les figures 10 et 12. La longueur du serre-nuque reste constante durant le réglage, tandis qu'on fait varier le positionnement de son point d'attache grâce à la crémaillère 30 localisée sur la paroi interne de la calotte 16.
The adjustment of the neckband 20 according to the invention is carried out as follows:
  • With both hands, the user simultaneously presses the two unlocking buttons 33 against the return springs 38. The lugs 42 of the coupling piece 40 leave the rack 30, which releases the ends EX1, EX2 of the neckband 20. It is then sufficient to move the slides 32 in translation in the slots 31 until the neckband 20 is in contact with the neck of the user. The release of the unlocking buttons 33 automatically returns the lugs 42 in the corresponding rack 30, ensuring the setting lock in the chosen position.
  • Instead of having both ends EX1, EX2 adjustable, it is also possible to have one fixed, and the other adjustable.
  • It is clear that the rack 30 can be replaced by any other indexing means in the piloted position from the outer slider.
  • The adjustment is rapid, and is operated from the outside on the lateral sides of the cap 16. No intervention is necessary at the back of the helmet 15, regardless of the type of neckband according to the figures 10 and 12 . The length of the neckband remains constant during the adjustment, while the positioning of its point of attachment is varied thanks to the rack 30 located on the inner wall of the cap 16.
