Description

PERFECTIONNEMENT POUR CASQUE DONT LA PARTIE INFERIEURE ARRIERE DE LA COQUE COMPREND DES MOYENS DE DEFORMATIONS ELASTIQUESIMPROVEMENT FOR A HELMET HAVING THE LOWER REAR PART OF THE HULL INCLUDING MEANS OF ELASTIC DEFORMATION
La présente invention concerne un perfectionnement pour casque, et plus particulièrement un casque dont la coque externe comprend des moyens de déformations élastiques dans sa partie inférieure arrière. Le casque est plus spécialement destiné à être porté par des pilotes d'avions ou d'hélicoptères, mais cela de façon non exclusive, puisque l'invention peut être utilisée pour tout type de casque.The present invention relates to an improvement for a helmet, and more particularly to a helmet, the outer shell of which comprises elastic deformation means in its rear lower part. The helmet is more especially intended to be worn by pilots of airplanes or helicopters, but this in a non-exclusive manner, since the invention can be used for any type of helmet.
On connaît 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 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 emboîter la tête de l'utilisateur.Protective helmets are already known which are used in different fields and worn by various users such as cyclists, motorcyclists, firefighters, skiers and others, such as pilots of airplanes or helicopters. All current helmets, whatever their use, comprise an external rigid shell having the general shape of a sphere, comprising a facial opening, and the cavity thus formed comprises protective and comfort padding elements intended to fit the head of the user.
Pour chaque type d'utilisation, les constructeurs ont essayé de concevoir des casques ayant une configuration spécifique. Mais si beaucoup de perfectionnements ont ainsi été imaginés, développés et mis au point, tout n'a pas été fait. En effet, le confort général des casques actuels est, somme toute, satisfaisant dans son ensemble, mais il faut remarquer que le confort du casque au niveau de la nuque de l'utilisateur laisse à désirer, malgré la présence dans la plupart des casques actuels d'un rembourrage en matériau souple, ou d'une sangle disposée à l'intérieur de la partie arrière de la coque, des moyens de réglage assez complexes et coûteux étant alors prévus pour pouvoir adapter le rembourrage ou la sangle à la dimension et à la forme de la nuque de l'utilisateur.For each type of use, manufacturers have tried to design helmets with a specific configuration. But if a lot of improvements have been imagined, developed and perfected, everything has not been done. Indeed, the general comfort of current helmets is, on the whole, satisfactory as a whole, but it should be noted that the comfort of the helmet at the level of the neck of the user leaves something to be desired, despite the presence in most current helmets padding made of flexible material, or a strap placed inside the rear part of the shell, fairly complex and costly adjustment means then being provided in order to be able to adapt the padding or strap to the size and the shape of the user's neck.
La présente invention a pour but d'éliminer les inconvénients des dispositifs et systèmes actuels de tenue et de confort de nuque et propose un nouveau casque dont la partie arrière de la coque comprend des moyens d'adaptations élastiques particulièrement simples. L'adaptation à la nuque de l'utilisateur se faisant automatiquement, lui assurant ainsi un confort à ce jour jamais obtenu.The object of the present invention is to eliminate the drawbacks of the current devices and systems for holding and comforting the neck and proposes a new helmet, the rear part of the shell of which comprises particularly simple elastic adaptation means. Adaptation to the neck of the user being done automatically, thus ensuring comfort to date never obtained.
Ainsi le casque de protection selon l'invention est du type comprenant une coque externe principale constituée par une paroi présentant une ouverture faciale avant, et est caractérisé en ce que la portion inférieure arrière de la paroi comprend des moyens de déformations élastiques, la coque externe principale étant en matériau déformable.Thus the protective helmet according to the invention is of the type comprising a main external shell constituted by a wall having a front facial opening, and is characterized in that the lower rear portion of the wall comprises means of elastic deformation, the external shell main being of deformable material.
Selon des caractéristiques complémentaires, la paroi de la coque externe est en matière plastique, ou en matériau composite du type par exemple constitué d'au moins une couche de fibres de verre et/ou de carbone et/ou d'aramide ou autre, imprégnée d'une résine thermoplastique ou thermodurcissable.According to additional characteristics, the wall of the outer shell is made of plastic, or of composite material of the type for example consisting of at least one layer of glass fibers and / or carbon and / or aramid or the like, impregnated a thermoplastic or thermosetting resin.
La coque externe principale du casque de l'invention, comprend plusieurs portions de paroi, à savoir, une portion avant supérieure de paroi prolongée vers l'arrière par une portion arrière supérieure de paroi, elle-même prolongée vers le bas par une portion arrière inférieure de paroi, limitée vers le bas par une bordure inférieure, ladite portion arrière inférieure de paroi comprenant au moins une ouverture de découpe, qui avantageusement débouche vers le bas sur la bordure inférieure.The main outer shell of the helmet of the invention comprises several wall portions, namely, an upper front wall portion extended rearwards by an upper rear wall portion, itself extended downwards by a rear portion lower wall, limited downwards by a lower border, said lower rear wall portion comprising at least one cutout opening, which advantageously opens downwards on the lower border.
Selon différents modes d'exécution, la portion arrière inférieure de paroi comprend deux, trois ou quatre, ou plus, découpes latérales, ayant la forme d'une fente.According to different embodiments, the lower rear wall portion comprises two, three or four, or more, side cutouts, having the shape of a slot.
Dans une disposition préférée, le casque de protection comprend un coussin de nuque retenu dans la coque, en partie par les découpes de la paroi.In a preferred arrangement, the protective helmet comprises a neck cushion retained in the shell, in part by the cutouts in the wall.
D'autres caractéristiques et avantages de l'invention se dégageront de la description qui va suivre en regard des dessins annexés qui ne sont donnés qu'à titre d'exemples non limitatifs. La figure 1 est une vue latérale extérieure d'un casque selon l'invention.Other characteristics and advantages of the invention will emerge from the description which follows with reference to the appended drawings which are given only by way of nonlimiting examples. Figure 1 is an external side view of a helmet according to the invention.

Les figures 6 et 7 montrent la coque seule, dans une vue avant (figure 6) et dans une vue arrière (figure 7).Figures 6 and 7 show the shell alone, in a front view (Figure 6) and in a rear view (Figure 7).
La figure 8 est une vue arrière en perspective, tandis que la figure 9 montre dans les mêmes conditions le coussin de nuque avec ses moyens d'accrochage.Figure 8 is a rear perspective view, while Figure 9 shows under the same conditions the neck cushion with its attachment means.
Les figures 10 à 18 sont des vues arrières similaires à la figure 7 représentant à une autre échelle et schématiquement neuf variantes d'exécution possibles données à titre d'exemple.Figures 10 to 18 are rear views similar to Figure 7 showing on another scale and schematically nine possible alternative embodiments given by way of example.
Les figures 19a, 19b sont des vues similaires aux figures 8 et 9 illustrant une variante d'exécution.Figures 19a, 19b are views similar to Figures 8 and 9 illustrating an alternative embodiment.
Les figures 20 et 21 sont des vues partielles schématiques montrant comment pourrait être aussi retenue le coussin de nuque.Figures 20 and 21 are schematic partial views showing how the neck cushion could also be retained.
Notons que pour simplifier les dessins, la jugulaire du casque donnée à titre d'exemple et qui est bien connue en soi par ailleurs et qui peut être de tout type, n'a volontairement pas été représentée.Note that to simplify the drawings, the chin strap of the helmet given by way of example and which is well known per se elsewhere and which can be of any type, has not been deliberately shown.
Le casque de protection représenté à titre d'exemple aux figures 1 à 9, portant la référence générale (1) est notamment un casque pour pilote d'avion, 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) avec un rembourrage interne appelé communément calotin (4).The protective helmet shown by way of example in FIGS. 1 to 9, bearing the general reference (1) is in particular a helmet for an airplane pilot, 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) with an internal padding commonly called cap (4).
La coque externe principale (2) est constituée par une paroi (5) 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.The main external shell (2) is constituted by a substantially spherical wall (5) of general vertical plane of symmetry (P) which is advantageously made of composite material of the type comprising a stack of layers of reinforcing fibers, impregnated and bonded together by a resin matrix. The fibers can be glass, aramid, nylon, polyethylene or carbon fibers, while the matrix can be a resin of the thermosetting or thermoplastic type.
La coque externe principale (2) comprend plusieurs portions de paroi, à savoir, une portion avant supérieure de paroi (6) prolongée vers l'arrière par une portion arrière supérieure de paroi (7), elle-même prolongée vers le bas par une portion arrière inférieure de paroi (8), et comprend, par ailleurs, deux portions latérales de paroi (9a, 9b). La portion avant supérieure (6) correspond à la zone occupée par le front de l'utilisateur et est limitée par la bordure supérieure (10) de l'ouverture faciale (3) qui, quant à elle, est limitée latéralement par deux bordures latérales (lia, 11b). La portion arrière supérieure de paroi (7) correspond à la zone occupée par la boîte crânienne de l'utilisateur, tandis que la portion arrière inférieure de paroi (8) correspond à zone occupée par la nuque de l'utilisateur. Ajoutons à cela que la paroi (5) de la calotte est limitée vers le bas par une bordure inférieure (12) s'étendant dans un plan général (Q) incliné par rapport au plan horizontal (H) pour s'étendre vers l'arrière (AR) et vers le haut (HA). Les portions latérales de paroi (9a, 9b) correspondent aux zones occupées par les oreilles de l'utilisateur et sont limitées vers l'avant par la bordure latérale correspondante (l ia, 11b) de l'ouverture faciale (3) et vers le bas par les extrémités avant de la bordure inférieure (12).The main external shell (2) comprises several wall portions, namely, an upper front wall portion (6) extended rearwards by an upper rear wall portion (7), itself extended downwards by a lower rear wall portion (8), and further includes two side wall portions (9a, 9b). The upper front portion (6) corresponds to the zone occupied by the forehead of the user and is limited by the upper border (10) of the facial opening (3) which, in turn, is limited laterally by two lateral borders (11a, 11b). The upper rear wall portion (7) corresponds to the area occupied by the user's skull, while the lower rear wall portion (8) corresponds to the area occupied by the user's neck. Add to this that the wall (5) of the cap is limited downwards by a lower border (12) extending in a general plane (Q) inclined relative to the horizontal plane (H) to extend towards the back (AR) and up (HA). The lateral wall portions (9a, 9b) correspond to the areas occupied by the ears of the user and are limited towards the front by the corresponding lateral border (l ia, 11b) of the facial opening (3) and towards the bottom by the front ends of the lower border (12).
Selon l'invention, la portion arrière inférieure de paroi (8) de la coque externe limitée vers le bas par la bordure inférieure (12) comprend des moyens de déformations élastiques qui permettent un ajustement précis et un confort du port du casque dans la zone de la nuque de l'utilisateur.According to the invention, the lower rear wall portion (8) of the outer shell bounded downwards by the lower edge (12) comprises elastic deformation means which allow a precise adjustment and comfort of wearing a helmet in the user's neck area.
Dans le mode d'exécution illustré aux figures 1 à 9 et donné à titre d'exemple, la partie arrière inférieure de la coque comprend ainsi des ouvertures ou découpes (13, 14a, 14b) qui avantageusement débouchent vers le bas (BA) sur la bordure inférieure (12). Selon le mode d'exécution illustré par les figures 1 à 9, il est prévu trois ouvertures ou découpes (13, 14a, 14b) ayant la forme de fentes ouvertes sur la bordure inférieure pour créer ainsi deux languettes déformables (15a, 15b) et deux morceaux latéraux de paroi déformables (16a, 16b). La bordure inférieure (12) comprend donc trois encoches longitudinales (13, 14a, 14b), une encoche centrale (13) et deux encoches latérales (14a, 14b), donnant de la souplesse à la paroi du casque au niveau où se trouvent les ouvertures c'est-à-dire à la paroi inférieure arrière (8). Notons que les axes de symétrie générale (Xl-X'l, X2-X2, X3-X"3) des trois fentes (13, 14a, 14b) s'étendent vers le haut (HA) et avantageusement perpendiculairement à la bordure inférieure (12) sur une longueur (L).In the embodiment illustrated in Figures 1 to 9 and given by way of example, the lower rear part of the shell thus comprises openings or cutouts (13, 14a, 14b) which advantageously open downwards (BA) onto the lower edge (12). According to the embodiment illustrated in FIGS. 1 to 9, there are provided three openings or cutouts (13, 14a, 14b) having the form of open slots on the lower edge to thereby create two deformable tongues (15a, 15b) and two deformable side wall pieces (16a, 16b). The lower edge (12) therefore comprises three longitudinal notches (13, 14a, 14b), a central notch (13) and two lateral notches (14a, 14b), giving flexibility to the wall of the helmet at the level where the openings, that is to say at the rear rear wall (8). Note that the axes of general symmetry (Xl-X'l, X2-X2, X3-X "3) of the three slots (13, 14a, 14b) extend upwards (HA) and advantageously perpendicularly to the lower border (12) over a length (L).
Selon une disposition particulière, le casque comprend un coussin de nuque périphérique (17) disposé à l'intérieur de la coque au niveau de la bordure inférieure (12). Ce coussin de nuque (17) est constitué d'un rembourrage en mousse (18) enveloppé dans un habillage en tissu (19). Selon une construction préférée, le coussin de nuque (17) est retenu dans la coque, du moins en partie, par les encoches de déformation (13, 14a, 14b). A cet effet, il est prévu des saillies (20, 20a, 20b) solidaires du coussin de nuque (17) qui sont destinées à coopérer avec les encoches correspondantes (13, 14a, 14b) pour y être retenues. Ainsi, le coussin de nuque (17) est, par exemple, prolongé vers le haut par une paroi de retenue souple (21) sur laquelle sont fixées les trois saillies d'accrochage (20, 20a, 20b) comprenant chacune une partie cylindrique (200) dont l'extrémité comprend une collerette de retenue (201), comme on peut le voir plus particulièrement aux figures 4 et 9.According to a particular arrangement, the helmet comprises a peripheral neck cushion (17) arranged inside the shell at the level of the lower edge (12). This neck cushion (17) consists of a foam padding (18) wrapped in a fabric covering (19). According to a preferred construction, the neck cushion (17) is retained in the shell, at least in part, by the deformation notches (13, 14a, 14b). For this purpose, there are provided projections (20, 20a, 20b) integral with the neck cushion (17) which are intended to cooperate with the corresponding notches (13, 14a, 14b) to be retained there. Thus, the neck cushion (17) is, for example, extended upward by a flexible retaining wall (21) on which are fixed the three hooking projections (20, 20a, 20b) each comprising a cylindrical part ( 200), the end of which includes a retaining flange (201), as can be seen more particularly in FIGS. 4 and 9.
Notons aussi que la partie centrale (170) du coussin de nuque (17) est avantageusement prolongée latéralement vers l'avant par des prolongements latéraux (171 , 172) qui sont fixés à l'intérieur de la coque pour y être fixés à la face intérieure située au niveau de la bordure inférieure (12) et aux bordures latérales (l ia, 11b) de l'ouverture faciale. La fixation des prolongements latéraux (171 , 172) pouvant se faire par tout moyen tel que collage, accrochage par bande auto agrippante, clipsage ou autre.Note also that the central part (170) of the neck cushion (17) is advantageously extended laterally forwards by lateral extensions (171, 172) which are fixed inside the shell to be attached to the inner face located at the lower edge (12) and the side edges (l ia, 11b) of the facial opening. The fixing of the lateral extensions (171, 172) can be done by any means such as gluing, hanging by self-gripping tape, clipping or other.
Afin de donner au casque une meilleure présentation et finition d'ensemble, il est prévu un profilé de finition (22) plus particulièrement visible aux figures 1, 3, 4 et 5. Ledit profilé de finition (22) ayant la forme d'un U étant en matière plastique souple et emboîté sur la bordure inférieure (12) en assurant la continuité avec la bordure des trois fentes (13, 14a, 14b).In order to give the helmet a better overall presentation and finish, a finishing profile (22) is more particularly visible in FIGS. 1, 3, 4 and 5. Said finishing profile (22) having the shape of a U being made of flexible plastic material and fitted on the lower edge (12) ensuring continuity with the edge of the three slots (13, 14a, 14b).
Par ailleurs, l'habillage interne de la coque (2) est constitué par un calotin (4), par exemple, en mousse rigide recouverte d'une couche de mousse souple de confort et d'un ussu qui assure la décoration interne du casque. Notons aussi que la partie arrière du calotin est prolongée par une bande de confort arrière (26) réalisée en mousse souple et sous laquelle est engagée la paroi de retenue (21) du coussin de nuque, comme cela apparaît plus particulièrement à la figure 4.Furthermore, the internal covering of the shell (2) is constituted by a cap (4), for example, of rigid foam covered with a layer of flexible comfort foam and of a ussu which ensures the internal decoration of the helmet. . Note also that the rear part of the cap is extended by a rear comfort strip (26) made of flexible foam and under which is engaged the retaining wall (21) of the neck cushion, as appears more particularly in FIG. 4.
Selon le mode d'exécution représenté à titre d'exemple, les découpes (13, 14a, 14b) faites dans la paroi (5) de la partie arrière inférieure (8) de la coque (2) sont au nombre de trois, de même longueur et de même largeur, mais il pourrait en être, bien entendu, tout autrement et par exemple, il pourrait n'y avoir qu'une seule fente (13), comme cela est illustré à la figure 10, ou deux découpes (14a, 14b) tel qu'illustré à la figure 11. Il pourrait, bien évidemment, y avoir plus de trois découpes, comme selon la réalisation de la figure 12 où il est prévu quatre découpes (14a, 14'a, 14b, 14'b).According to the embodiment shown by way of example, the cutouts (13, 14a, 14b) made in the wall (5) of the lower rear part (8) of the shell (2) are three in number, of same length and same width, but it could be, of course, quite different and for example, there could be only one slot (13), as illustrated in Figure 10, or two cutouts ( 14a, 14b) as illustrated in FIG. 11. There could, of course, be more than three cutouts, as according to the embodiment of FIG. 12 where four cutouts are provided (14a, 14'a, 14b, 14 'b).
Par ailleurs, dans les illustrations précédentes, les découpes sont de même longueur "L" et de même largeur "1", mais il pourrait en être autrement, comme cela est illustré schématiquement par les figures 13, 14,Furthermore, in the previous illustrations, the cutouts are of the same length "L" and of the same width "1", but it could be otherwise, as illustrated diagrammatically by FIGS. 13, 14,
15 et 16, qui représentent quatre autres variantes possibles. Dans les deux variantes des figures 13 et 14, les découpes (13, 14a, 14b) ont des longueurs différentes tandis que dans les variantes de la figure 15, c'est leurs largeurs qui sont différentes.15 and 16, which represent four other possible variants. In the two variants of FIGS. 13 and 14, the cutouts (13, 14a, 14b) have different lengths while in the variants of Figure 15, it is their widths which are different.
Notons aussi que les découpes (13, 14a, 14b, 14'a, 14'b) qui débouchent sur la bordure inférieure (12) sont des fentes longitudinales s'étendant vers le haut de la coque, mais il pourrait en être autrement comme cela est, par exemple, illustré aux figures 17 et 18 qui montrent deux autres mode d'exécution possibles.Note also that the cutouts (13, 14a, 14b, 14'a, 14'b) which open onto the lower edge (12) are longitudinal slots extending upwards from the shell, but it could be otherwise as this is, for example, illustrated in Figures 17 and 18 which show two other possible embodiments.
Le casque selon l'invention peut, il va de soi, comporter un ou plusieurs écran facial de protection pivotant tel que, par exemple, illustré et portant la référence (50).The helmet according to the invention can, it goes without saying, comprise one or more pivoting protective face shield such as, for example, illustrated and bearing the reference (50).
Les figures 19a et 19b illustrent une variante d'exécution selon laquelle la retenue du coussin de nuque (17) est constituée par des saillies (20, 20a, 20b) qui sont engagées dans des trous correspondants (200, 200a, 200b) réalisés dans la paroi du casque.Figures 19a and 19b illustrate an alternative embodiment according to which the retaining of the neck cushion (17) is constituted by projections (20, 20a, 20b) which are engaged in corresponding holes (200, 200a, 200b) made in the helmet wall.
Par ailleurs, notons que le profilé de finition (22) pourrait participer à la retenue du coussin de nuque (17) en retenant de façon active les saillies d'accrochage (20, 20a, 20b). Ainsi, et comme cela est illustré à la figure 20, il peut être prévu des saillies de retenue (220) sur le profil de finition (22) destinées à retenir la partie cylindrique (200) des saillies d'accrochage (20, 20a, 20b) du coussin de nuque (17). La figure 21 représente une variante selon laquelle le profilé de finition comprend une saillie périphérique (221) destinée à retenir la collerette (201) de la saillie d'accrochage (20, 20a, 20b) des saillies d'accrochage (20, 20a, 20b) du coussin de nuque.Furthermore, note that the finishing profile (22) could participate in retaining the neck cushion (17) by actively retaining the hooking projections (20, 20a, 20b). Thus, and as illustrated in FIG. 20, retaining projections (220) can be provided on the finishing profile (22) intended to retain the cylindrical part (200) of the hooking projections (20, 20a, 20b) of the neck cushion (17). FIG. 21 represents a variant according to which the finishing profile comprises a peripheral projection (221) intended to retain the flange (201) of the latching projection (20, 20a, 20b) of the latching projections (20, 20a, 20b) of the neck cushion.
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 embodiments described and shown by way of examples, but it also includes all the technical equivalents and their combinations.
