Description

La présente invention a pour objet un casque de protection pour conducteur ou passager d'engins, comprenant une coque, rigide et résistante aux chocs, destinée à protéger le front, le sommet du crâne, les tempes, la partie occipitale du crâne ainsi que le nuque et une jugulaire associée à ladite coque pour assujettir le casque et empêcher son arrachement en cas de chocs.The present invention relates to a protective helmet for driver or passenger of vehicles, comprising a shell, rigid and impact resistant, intended to protect the forehead, the top of the skull, the temples, the occipital part of the skull as well as the neck and chinstrap associated with said shell to secure the helmet and prevent its tearing in the event of impact.

On a déjà proposé diverses solutions pour, d'une part, tenter d'assurer à un casque son rôle protecteur de la tête et de la nuque quelles que soient les contraintes qu'il subisse lors de chocs et, d'autre part, tenter d'éviter l'arrachement du casque suite à ces chocs et ce, tout en tentant de conserver au casque un certain confort, une certaine facilité d'utilisation et une possibilité d'enlever le casque lorsqu'il a subi une déformation suite à un accident. Ces diverses solutions présentent toutefois l'inconvénient de présenter des lacunes dans l'un ou l'autre des domaines évoqués ci-dessus.Various solutions have already been proposed for, on the one hand, trying to ensure that a helmet has a protective role for the head and neck whatever the stresses it undergoes on impact, and, on the other hand, trying to to avoid the helmet being torn off following these shocks and this, while trying to keep the helmet a certain comfort, a certain ease of use and a possibility of removing the helmet when it has undergone a deformation following a accident. However, these various solutions have the drawback of having gaps in one or other of the fields mentioned above.

L'invention a pour but de remédier à cet inconvénient et de procurer un casque dont la coque, réalisée en une seule pièce, est conçue pour offrir une égale résistance sur toute sa surface et assurer ainsi une protection efficace de l'ensemble des parties vulnérables et fragiles de la tête et de la nuque, ce casque offrant également les avantages suivants : assujettissement du casque aisé et automatique grâce à sa jugulaire articulée, grande facilité d'introduction et de retrait de la tête, blocage de la jugulaire en position opérante en vue d'empêcher l'arrachement du casque sous des chocs et quelle que soit la direction de ceux-ci et possibili­té d'enlèvement du casque même en cas de déformation de sa coque.The invention aims to remedy this drawback and to provide a helmet whose shell, made in one piece, is designed to offer equal resistance over its entire surface and thus ensure effective protection of all vulnerable parts and fragile of the head and the nape of the neck, this helmet also offers the following advantages: easy and automatic subjection of the helmet thanks to its articulated chin strap, great ease of introduction and removal of the head, blocking of the chin strap in operating position in view to prevent the helmet from being torn off under impacts and regardless of the direction of these impacts and possibility of removing the helmet even in the event of deformation of its shell.

A cet effet, suivant l'invention, une des extrémités de la jugulaire est montée à rotation sur un pivot fixé à la coque et dont l'axe est sensiblement parallèle à une droite passant par les oreilles, l'autre extrémité de la jugulaire étant assemblée à la coque par l'intermédiaire de moyens pourvus d'un organe de commande, monté à rotation sur un pivot fixé à la coque et d'axe sensiblement parallèle à la droite précitée, et agencés pour déplacer la jugulaire entre deux positions extrêmes, une première position permettant soit la pose du casque soit le dégagement de la tête de ce dernier, dans laquelle la jugulaire est projetée en avant du menton pour libérer totalement l'ouverture du casque et une seconde position, correspondant à l'assujettissement du casque, dans laquelle la partie de la jugulaire destinée à prendre appui sous le menton pour assujettir le casque est en appui sous le menton, lesdits moyens étant en outre agencés pour que, d'une part, lorsque la jugulaire est déplacée de sa première à sa seconde position extrême, chaque point de la partie susdite de la jugulaire décrive sensiblement un arc de cercle dont le centre est situé sur l'axe du pivot autour duquel tourne l'organe de commande afin de contourner le menton et ensuite, lorsque ladite partie est située en regard de l'endroit où elle prend appui sous le menton assujettir le casque, pour que cette partie de jugulaire soit animée d'un mouvement de translation, sensiblement rectiligne, en direction de l'axe dudit pivot pour prendre fermement appui sous le menton et, d'autre part, lorsque la jugulaire passe de la seconde à la première position extrême, la partie susdite de la jugulaire s'écarte du menton suivant un mouvement de translation sensiblement rectiligne pour s'écarter de l'axe dudit pivot pour ensuite décrire son mouvement sensiblement circulaire afin de contourner le menton et libérer l'ouverture du casque, les moyens précités compre­nant des moyens de blocage de la jugulaire lorsque celle-ci occupe sa seconde position extrême.To this end, according to the invention, one end of the chin strap is rotatably mounted on a pivot fixed to the shell and whose axis is substantially parallel to a passing straight line. by the ears, the other end of the chin strap being assembled to the hull by means of means provided with a control member, mounted for rotation on a pivot fixed to the hull and with an axis substantially parallel to the aforementioned straight line , and arranged to move the chin strap between two extreme positions, a first position allowing either the fitting of the helmet or the release of the head of the latter, in which the chin strap is projected in front of the chin to completely release the opening of the helmet and a second position, corresponding to the securing of the helmet, in which the part of the chin strap intended to bear under the chin to secure the helmet is in support under the chin, said means being further arranged so that, on the one hand , when the chinstrap is moved from its first to its second extreme position, each point of the aforesaid part of the chinstrap substantially describes an arc of a circle whose center is located on the axis of the pivot autou r which rotates the control member in order to bypass the chin and then, when said part is located opposite the place where it rests under the chin, secure the helmet, so that this chin strap part is animated by a movement translational, substantially rectilinear, in the direction of the axis of said pivot to take firm support under the chin and, on the other hand, when the chin strap goes from the second to the first extreme position, the aforesaid part of the chin strap moves away chin in a substantially rectilinear translational movement to move away from the axis of said pivot to then describe its substantially circular movement in order to bypass the chin and release the opening of the helmet, the aforementioned means comprising means for blocking the chin strap when it occupies its second extreme position.

Suivant un mode de réalisation particulier de l'invention,les deux extrémités de la jugulaire sont assemblées à la coque par l'intermédiaire des moyens précités, ceux-ci étant identi­ques et comprenant chacun l'organe de commande susdit et les moyens de blocage de la jugulaire, ces organes de commande étant montés sur des pivots fixés à la coque et dont les axes sont confondus et sensiblement parallèles à la droite passant par les oreilles.According to a particular embodiment of the invention, the two ends of the chin strap are assembled to the shell by means of the aforementioned means, these being identical and each comprising the above-mentioned control member and the locking means for the chin strap, these control members being mounted on pivots fixed to the shell and whose axes are coincident and substantially parallel to the right passing through the ears.

Suivant une forme de réalisation avantageuse de l'invention, les organes de commande des moyens susdits sont réunis entre eux par un arceau, ce dernier étant agencé pour être situé en avant du menton, pour libérer totalement l'ouverture du casque, lorsque la jugulaire occupe sa première position extrême précitée.According to an advantageous embodiment of the invention, the control members of the aforementioned means are joined together by a hoop, the latter being arranged to be located in front of the chin, to completely release the opening of the helmet, when the chin strap occupies its first aforementioned extreme position.

Suivant un mode de réalisation particulièrement avantageux de l'invention, l'arceau susdit est profilé de manière à constituer une mentonnière.According to a particularly advantageous embodiment of the invention, the aforementioned arch is profiled so as to constitute a chin rest.

Le casque suivant l'invention et illustré aux dessins comprend une coque 1 (représentée en pointillés aux figures 1 à 3), réalisée en une seule pièce, en un matériau rigide et résistant aux chocs, qui est destinée à protéger toutes les parties vulnérables de la tête, à savoir au moins le front, le sommet du crâne, les tempes, la partie occipitale du crâne ainsi que la nuque, et une jugulaire 2 associée à la coque 1 pour assujettir fermement le casque et empêcher son arrachement en cas de choc, quelle que soit la direction de celui-­ci. Dans la forme de réalisation du casque montrée à la figure 1, l'extrémité 3 de la jugulaire 2 est montée à rotation sur un pivot 4 fixé à la coque et dont l'axe 5 est parallèle à une droite 6 (figure 9) passant par les oreilles, l'extrémité 7 de la jugulaire 2 étant assem­blée à la coque 1 par l'intermédiaire de moyens 8 comprenant un organe de commande 9, monté à rotation sur un pivot 10 fixé à ladite coque 1 et d'axe 11 sensiblement parallèle à la droite 6 précitée. Ces moyens 8 sont agencés pour déplacer la jugulaire 2 entre deux positions extrêmes, une première position (représentée en traits inter­rompus) permettant soit la pose du casque, soit le dégagement de la tête de celui-ci, dans laquelle la jugulaire 2 est projetée en avant du menton afin de libérer totalement l'ouverture située à la base du casque et une seconde position (représentée en traits pleins) corres­pondant à l'assujettissement du casque, dans laquelle la partie 12 de la jugulaire 2 destinée à prendre appui sous le menton pour assujettir le casque est en appui sous le menton. Les moyens 8 sont également agencés pour que, d'une part, lorsque la jugulaire 2 est déplacée de sa première à sa seconde position extrême, chaque point de la partie 12 de la jugulaire décrive sensiblement un arc de cercle dont le centre est situé sur l'axe du pivot 10 autour duquel tourne l'organe de commande 9 afin de contourner le menton et ensuite, lorsque la partie 12 de la jugulaire est située en regard de l'endroit où elle prend appui sous le menton pour assujettir le casque, pour que cette partie 12 de jugulaire soit animée d'un mouvement de translation sensiblement rectiligne en direction de l'axe 11 du pivot 10 pour se rapprocher du menton et prendre fermement appui sous le menton et, d'autre part, lorsque la jugulaire 2 passe de sa seconde à sa première position extrême, la partie 12 de la jugulaire s'écarte du menton suivant un mouvement de translation sensiblement rectiligne pour s'éloigner de l'axe 11 du pivot 10 et pour ensuite décrire son mouvement sensiblement circulaire afin de contourner le menton et libérer totalement l'ouverture située à la base du casque, les moyens 8 comprenant encore des moyens de blocage 13 (figure 5) pour immobili­ser cette dernière lorsqu'elle occupe sa seconde position extrême et permettre ainsi à la jugulaire de s'opposer efficacement à l'arrache­ment du casque quelles que soient les contraintes qu'il subit sous l'effet de chocs.The helmet according to the invention and illustrated in the drawings comprises a shell 1 (shown in dotted lines in Figures 1 to 3), made in one piece, in a rigid and impact-resistant material, which is intended to protect all the vulnerable parts of the head, namely at least the forehead, the top of the skull, the temples, the occipital part of the skull as well as the nape of the neck, and a chin strap 2 associated with the shell 1 to firmly secure the helmet and prevent it from being torn off in the event of impact , whatever the direction of it. In the embodiment of the helmet shown in Figure 1, the end 3 of the chin strap 2 is rotatably mounted on a pivot 4 fixed to the shell and whose axis 5 is parallel to a straight line 6 (Figure 9) by the ears, the end 7 of the chin strap 2 being assembled to the shell 1 by means of means 8 comprising a control member 9, mounted for rotation on a pivot 10 fixed to said shell 1 and of axis 11 substantially parallel to line 6 above. These means 8 are arranged to move the chin strap 2 between two extreme positions, a first position (shown in broken lines) allowing either the fitting of the helmet, or the release of the head thereof, in which the chin strap 2 is projected in front of the chin in order to completely release the opening located at the base of the helmet and a second position (shown in solid lines) corresponding to the securing of the helmet, in which the part 12 of the chin strap 2 intended to rest under the chin to secure the helmet is supported under the chin. The means 8 are also arranged so that, on the one hand, when the chin strap 2 is moved from its first to its second extreme position, each point of the part 12 of the chin strap substantially describes an arc of a circle, the center is located on the axis of the pivot 10 around which the control member 9 rotates in order to bypass the chin and then, when the part 12 of the chin strap is located opposite the place where it rests under the chin to secure the helmet, so that this part 12 of the chin strap is animated by a substantially rectilinear translational movement in the direction of the axis 11 of the pivot 10 in order to approach the chin and take firm support under the chin and, on the other hand , when the chin strap 2 goes from its second to its first extreme position, the part 12 of the chin strap moves away from the chin in a substantially rectilinear translational movement to move away from the axis 11 of the pivot 10 and then describe its substantially circular movement in order to bypass the chin and completely release the opening located at the base of the helmet, the means 8 further comprising blocking means 13 (FIG. 5) for immobilizing the latter when it occupies its second position extreme ion and thus allow the chin strap to effectively oppose the tearing of the helmet regardless of the stresses it undergoes under impact.

Dans la forme de réalisation du casque illustrée à la figure 2, les deux extrémités 3 et 7 de la jugulaire 2 sont assem­blées chacune à la coque 1 par l'intermédiaire des moyens 8 tels que décrits ci-dessus. Ces moyens 8, associés auxdites extrémités 3 et 7 de la jugulaire sont identiques et comprennent chacun un organe de commande 9 et les moyens de blocage 13 de la jugulaire lorsque celle-ci occupe sa seconde position extrême, les deux organes de commande 9 étant montés sur deux pivots 10 fixés à la coque 1. Les axes 11 de ces pivots 10 sont confondus et sensiblement parallèles à la droite 6 précitée. Les organes de commande 9 sont à actionner séparément et simultanément pour faire passer la jugulaire 2 de sa première position à se seconde position extrême et vice-versa.In the embodiment of the helmet illustrated in FIG. 2, the two ends 3 and 7 of the chin strap 2 are each assembled to the shell 1 by means 8 as described above. These means 8, associated with said ends 3 and 7 of the chin strap are identical and each comprise a control member 9 and the blocking means 13 of the chin strap when the latter occupies its second extreme position, the two control members 9 being mounted on two pivots 10 fixed to the shell 1. The axes 11 of these pivots 10 are coincident and substantially parallel to the straight line 6 above. The control members 9 are to be actuated separately and simultaneously to move the chinstrap 2 from its first position to the second extreme position and vice versa.

Pour faciliter la commande de la jugulaire 2 et permettre celle-ci à l'aide d'une seule main, les organes de commande 9 sont avantageusement, comme illustré à la figure 3, réunis entre eux par un arceau 14 joignant les extrémités desdits organes 9 opposées aux pivots 10. Cet arceau 14 est agencé pour pouvoir être projeté en avant du menton, pour libérer totalement l'ouverture située à la base du casque, lorsque les organes 9 occupent leur position correspondant à la première position extrême de la jugulaire 2. Cet arceau 14 est avantageusement profilé, comme montré à la figure 4, pour constituer, dans le cas d'un casque dit "intégral", une mentonnière 15 destinée à protéger le menton des chocs. Cette mentonnière 15 est avantageusement profilée pour s'adapter à la forme de la coque 1 et prendre appui sur cette dernière, le long des lignes 16, quand la jugulaire 2 occupe sa seconde position extrême et afin que les efforts résultant des chocs sur la mentonnière soient repris par la coque 1.To facilitate the control of the chin strap 2 and allow it with one hand, the control members 9 are advantageously, as illustrated in Figure 3, joined together by a hoop 14 joining the ends of said members 9 opposite the pivots 10. This arch 14 is arranged to be able to be projected in front of the chin, to completely release the opening located at the base of the helmet, when the members 9 occupy their position corresponding to the first extreme position of the chin strap 2. This arch 14 is advantageously profiled, as shown in FIG. 4, to constitute, in the case of a so-called "full face helmet", a chin guard 15 intended to protect the chin from shocks. This chin guard 15 is advantageously profiled to adapt to the shape of the shell 1 and to rest on the latter, along the lines 16, when the chin strap 2 occupies its second extreme position and so that the forces resulting from impacts on the chin guard are taken up by shell 1.

Pour éviter l'arrachement du casque en cas de choc, les moyens de blocage 13 de la jugulaire sont agencés pour s'opposer, quand la jugulaire 2 occupe sa seconde position extrême, c'est-à-dire en pression sous le menton, à tout mouvement de rotation de ladite jugulaire 2 autour de l'axe 11 du ou des pivots 10 de l'organe de commande unique ou des deux organes de commande 9 et à tout mouvement transversal de ladite jugulaire, dans un sens ou dans l'autre, par rapport audit axe 11.To prevent the helmet from being torn off in the event of an impact, the blocking means 13 of the chin strap are arranged to oppose, when the chin strap 2 occupies its second extreme position, that is to say under pressure under the chin, to any rotational movement of said chin strap 2 about the axis 11 of the pivot (s) 10 of the single control member or of the two control members 9 and to any transverse movement of said chin strap, in one direction or in the other, with respect to said axis 11.

Pour éviter un déplacement accidentel, en cas de choc, du ou des organes de commande 9, le casque suivant l'invention comprend avantageusement, comme montré aux figures 4 et 8 à 10, des moyens d'immobilisation 17 du ou des organes de commande par rapport à la coque 1. Ces moyens 17 sont agencés pour s'opposer à tout mouvement de rotation du ou des organes 9, autour de l'axe 11 du ou des pivots 10, quand ils occupent leur position correspondant à la seconde position extrême de la jugulaire 2, c'est-à-dire la position d'assujettissement du casque.To avoid accidental displacement, in the event of an impact, of the control member (s) 9, the helmet according to the invention advantageously comprises, as shown in FIGS. 4 and 8 to 10, immobilization means 17 of the control member (s) relative to the shell 1. These means 17 are arranged to oppose any movement of rotation of the member (s) 9, around the axis 11 of the pivot (s) 10, when they occupy their position corresponding to the second extreme position chin strap 2, that is to say the helmet fastening position.

Comme illustré aux figures 5 à 7, les moyens 8, par l'intermédiaire desquels la ou les extrémités 3 et 7 de la jugulaire 2 sont montées sur la coque 1 du casque, comprennent un ergot 18 fixé à cette coque et d'axe parallèle à la droite 6 susdite passant par les oreilles, une encoche 19, profilée pour assurer les mouvements de rotation et de translation de la jugulaire 2, réalisée à l'extrémité de la jugulaire (3, 7) et dans laquelle peut se déplacer l'ergot 18, une première biellette 20 dont l'extrémité 21 est montée à pivotement sur l'organe de commande 9, tandis que son autre extrémité 22 est montée à pivotement sur l'extrémité 3, 7 de la jugulaire, une seconde biellette 23 dont l'extrémité 24 est montée à pivotement sur la jugulaire 2 autour d'un axe 25 commun à la première biellette 20 et dont l'autre extrémité 26 est montée à pivotement sur la coque 1 du casque, les axes 25, 27 et 28 des biellettes 20 et 23 étant parallèles à la droite 6 précitée. Lesdits moyens 8 comprennent également un ergot 29, d'axe parallèle à la droite 6, fixé à la jugulaire 2 et destiné à venir buter, lorsque celle-ci passe de sa première position extrême à sa seconde position extrême, contre une rampe 30 prévue dans la coque 1 du casque pour s'engager dans un évidement rectiligne 31 ménagé dans ladite coque et orienté vers le pivot 10 autour duquel tourne l'organe de commande 9.As illustrated in FIGS. 5 to 7, the means 8, via which the end or ends 3 and 7 of the chin strap 2 are mounted on the shell 1 of the helmet, comprise a lug 18 fixed to this shell and with a parallel axis to the right 6 above passing through the ears, a notch 19, profiled to ensure the rotational and translational movements of the chin strap 2, produced at the end of the chin strap (3, 7) and in which the lug 18, a first link 20 whose end 21 is pivotally mounted on the control member 9, while its other end 22 is pivotally mounted on the end 3, 7 of the chin strap, a second link 23 whose end 24 is pivotally mounted on the chin strap 2 around a axis 25 common to the first link 20 and the other end 26 of which is pivotally mounted on the shell 1 of the helmet, the axes 25, 27 and 28 of the links 20 and 23 being parallel to the above-mentioned straight line 6. Said means 8 also comprise a lug 29, with an axis parallel to the right 6, fixed to the chin strap 2 and intended to come into abutment, when the latter passes from its first extreme position to its second extreme position, against a ramp 30 provided in the shell 1 of the helmet to engage in a rectilinear recess 31 formed in said shell and oriented towards the pivot 10 around which the control member 9 rotates.

Les moyens de blocage 13 précités de la jugulaire 2 lorsque celle-ci occupe sa seconde position extrême, c'est-à-­dire sa position d'assujettissement du casque, sont constitués, d'une part, par cet évidement 31, qui emprisonne l'ergot 29 et empêche de ce fait tout mouvement de rotation de la jugulaire 2 et, d'autre part, par un second évidement 32 ménagé dans l'organe de commande 9 et s'étendant suivant une direction sensiblement perpendiculaire à l'évidement 31. Dans cet évidement 32 vient se loger l'axe commun 25 des biellettes 20 et 23, l'emprisonnement dudit axe 25 dans cet évidement 32 s'opposant à tout mouvement de translation de la jugulaire pour se rapprocher ou s'écarter du pivot 10 sur lequel est articulé l'organe de commande 9.The aforementioned blocking means 13 of the chin strap 2 when the latter occupies its second extreme position, that is to say its position for securing the helmet, consist, on the one hand, of this recess 31, which traps the lug 29 and thereby prevents any movement of rotation of the chin strap 2 and, on the other hand, by a second recess 32 formed in the control member 9 and extending in a direction substantially perpendicular to the recess 31. In this recess 32 is housed the common axis 25 of the rods 20 and 23, the confinement of said axis 25 in this recess 32 opposing any movement of translation of the chin strap to approach or move away from the pivot 10 on which the control member 9 is articulated.

Les moyens d'immobilisation 17 précités du ou des organes de commande 9 par rapport à la coque 1 du casque lorsque la jugulaire 2 occupe sa position d'assujettissement du casque (seconde position extrême) peuvent être constitués, comme montré à la figure 4, par un élément mâle 33 fixé à la coque et par un élément femelle 34 correspondant prévu dans l'organe 9, ces éléments étant agencés pour assurer le verrouillage automatique de l'organe 9 sur la coque 1 lorsque ledit organe 9 occupe sa position correspondant à la seconde position extrême de la jugulaire 2, un bouton de commande 35 étant prévu sur la coque pour assurer le déverrouillage de l'organe 9.The abovementioned immobilization means 17 of the control member (s) 9 relative to the shell 1 of the helmet when the chin strap 2 occupies its position for securing the helmet (second extreme position) can be formed, as shown in FIG. 4, by a male element 33 fixed to the shell and by a corresponding female element 34 provided in the member 9, these elements being arranged to ensure the automatic locking of the member 9 on the shell 1 when said member 9 occupies its position corresponding to the second extreme position of the chinstrap 2, a control button 35 being provided on the shell to unlock the member 9.

Les moyens d'immobilisation 17 susdits peuvent également être constitués, comme montré aux figures 8 à 10, par deux éléments souples 36 fixés, à leur extrémité 37, à la coque 1 et coulissant dans deux canaux 38 pratiqués à la base de la mentonnière 15. Les extrémités 38ʹ des éléments 36 sont profilées pour s'engager automatiquement dans les pattes 39 d'un verrou 40 qui les retient fermement lorsque la mentonnière est dans sa position qui correspond à l'assujettissement du casque (figure 9). Le verrou 40 est agencé pour qu'une pression exercée, suivant la flèche 41 et de l'intérieur du casque, libère les éléments 36 et permette le déplacement de la mentonnière 15 (figure 10) qui projette la jugulaire 2 en avant du menton. Pour permettre le mouvement de la mentonnière, en cas de déformation de cette dernière qui empêcherait le coulissement des éléments 36 dans les canaux 38, lesdits éléments souples 36 sont assemblés à la coque 1 du casque par des vis 42 qui, lorsqu'elles sont dévissées, permettent la libération des extrémités 37 desdits éléments 36.The above-mentioned immobilization means 17 can also be constituted, as shown in FIGS. 8 to 10, by two flexible elements 36 fixed, at their end 37, to the shell 1 and sliding in two channels 38 formed at the base of the chin rest 15 The ends 38ʹ of the elements 36 are profiled to automatically engage in the lugs 39 of a lock 40 which retains them firmly when the chin rest is in its position which corresponds to the securing of the helmet (FIG. 9). The lock 40 is arranged so that a pressure exerted, along arrow 41 and from inside the helmet, releases the elements 36 and allows the movement of the chin strap 15 (FIG. 10) which projects the chin strap 2 in front of the chin. To allow movement of the chin guard, in the event of deformation of the latter which would prevent the sliding of the elements 36 in the channels 38, said flexible elements 36 are assembled to the shell 1 of the helmet by screws 42 which, when they are unscrewed allow the ends 37 of said elements 36 to be released.

Il doit être entendu que l'invention n'est nullement limitée aux formes de réalisation décrites et que bien des modifications peuvent être apportées à ces dernières sans sortir du cadre du présent brevet.It should be understood that the invention is in no way limited to the embodiments described and that many modifications can be made to these without departing from the scope of this patent.

C'est ainsi notamment que, d'une part, les moyens 8 pourraient être constitués par des cames qui assureraient à la jugulaire 2 le mouvement décrit ci-dessus et, d'autre part, les moyens de blocage 13 et d'immobilisation 17 précités pourraient être constitués par des verrous à encliquetage automatique.Thus, in particular that, on the one hand, the means 8 could be constituted by cams which would provide the chinstrap 2 with the movement described above and, on the other hand, the locking and immobilizing means 17 aforementioned could be constituted by latches with automatic snap-fastening.
