Definitions
- the present invention relates to a "full" protection helmet, particularly for the practice of motorcycling.
- the present invention relates to a "full" type of protective helmet comprising a movable chin strap allowing different configurations of helmet use to be adopted depending on the position of said chin guard.
- the technical field of the invention is that of the design and manufacture of safety accessories for motorcycling, but also for other risky sports activities requiring the wearing of a helmet such as motoring, cycling or motorcycles. water sports such as jet skiing or offshore racing.
- Protective helmets known as "Integral” have long been known, consisting of a shell protecting the whole of the skull as well as the facial portion of the chin, and a transparent screen, generally pivotally mounted on the side walls of the body. shell, and to cover and protect the portion of the face located at the level of the eyes of the user.
- the full-face helmets prove to be the most satisfactory. Nevertheless, the chin protection of these helmets causes a lack of freedom during use, in that it is impossible to clear the face to discuss, for example, without removing the helmet completely when one is stopped , or that the heat makes the wearing of such a headphone "Integral” painful for the motorcyclist who can be sweated inside said helmet. In addition, people with glasses, can not put on or remove a headset "Integral" without removing beforehand their said glasses, which, again, is uncomfortable.
- helmets with a chinrest mobile relative to the rest of the shell thus allowing in a first position, called “closed”, the chin strap, to use the helmet in a configuration “Integral” helmet and, in a second position, called “open”, to clear the face of the motorcyclist while keeping the helmet on the skull.
- helmets are known as described in EP 0 395 845 whose chinrest can be moved towards the front of the shell to facilitate the installation of the helmet on the head of the user, then pushed back in abutment against the side walls of the shell to protect the user by traffic
- the chin strap of the helmet described in EP 0 395 845 can not be fully raised and / or spread on the front or sides of the helmet shell so as to clear the entire face to allow the user to roll face uncovered as with traditional "Jet" type helmets.
- An object of the present invention is to provide a movable chin strap which allows, in the closed position of the chinrest, to have the same degree of safety and sealing, between the screen and the chinrest, a helmet " Integral "classic.
- Another object of the present invention is to provide a helmet which also allows a complete clearance of the facial area of the helmet and a retraction of the chin guard in the open position thereof, to allow use of the helmet in helmet configuration type "Jet", that is to say without a chin guard, without risk to the user in case of fall or impact, as is the case with the helmet described in the document EP 1132274 A1 or EP 0993784 A1 .
- the invention also proposes to provide a movable chin-strap helmet that fulfills all the protection requirements required by the standards in force and that allows a transition from the closed position to the open position of the chin guard, and vice versa, to the help with one hand.
- Another object of the invention is to provide a helmet as described above, whose constitution is simple and whose shape is aerodynamically satisfactory whatever the open or closed position of the chinrest.
- a protective helmet particularly for motorcycling, having a shell on the side walls of which are fixed a screen pivotable relative to said shell and a movable chinrest able to be raised over said screen and tilted back beyond the top of said shell, from a closed position to an open position, said helmet being characterized in that, in said closed position, said screen is adapted to rest against a rim outer upper of said chin guard and in that said shell and said chin guard comprise complementary guide means such as the trajectory of said chin guard between said closed position and said open position, ie a non-circular path according to which said chin guard deviates all first of said shell and is raised and tilted over said screen, and finally gets closer said shell at the rear thereof.
- said shell of the helmet is intended to cover the skull of a user to protect it from shocks and that, in said closed position of the chin guard, it is positioned in front of said shell and covers the mandibular arch of the user's face to protect this part of the face in the event of a fall.
- the helmet according to the invention is particularly advantageous in that, in the closed position of the chinrest, the screen is able to bear against the upper outer rim of the chin guard, as is the case with the integral helmets classics.
- This allows, unlike the helmets proposed in the documents EP 0933784 and EP 1101419 , to guarantee a total imperviousness between the screen and the chinrest, when these are in closed position, as well as the suppression of the vibrations of the screen, during the driving, caused by the support of the wind and the air moved against said screen.
- this ensures an optimal security against the impacts on the screen, because of the support of the internal surface of said screen over the entire lower periphery thereof, against the upper edge of the chin guard.
- the helmet according to the invention also allows to completely clear the face of the user, by its movable chin guard whose movement is guided, so as to be able to use the helmet configuration "Jet" without risk of imbalance of the head, as is the case with lifting chinrests as described in the documents EP 0895726 A1 or EP 1183957 A1 .
- the guiding means provide a complex displacement of said chin guard, according to which the latter departs in a first step from the shell forward in a longitudinal direction, as well as on the sides in a transverse direction, to pass over the screen then, then pivots above the top of the hull aft, then finally approaches the hull in said longitudinal and transverse directions.
- the trajectory followed by the chinrest is non-circular but is also performed simultaneously in two orthogonal directions, which allows to pass over the screen from said closed position, in which the chinrest is recessed behind the screen, to said open position bearing against the occipital portion of the helmet shell.
- said guiding means of the shell and the chin strap respectively comprise sliding means and pivoting means, arranged so as to allow simultaneous movements of translation and rotation of said chin guard with respect to said shell and said screen, between said closed position and said open position of said chin guard.
- Such guiding means allow a combined movement in translation and rotation of the chin guard, without any hitting or blocking, between the open and closed positions of said chin guard, and vice versa, which allows the user to perform said movement easily and with one hand.
- the guide means also allow to adopt the chin bar stationary intermediate position between its "closed” and “open” positions.
- Such an intermediate position may for example be a holding position of the chinrest in the frontal position on the front of the helmet shell, this position allowing the user, for example, to "put on” his helmet without having to remove his glasses or while continuing to talk with someone.
- said sliding means and said pivoting means comprise at least one male element on a side wall of said shell or on said chinrest, cooperating with at least one female element on said chinrest or on a wall lateral of said shell respectively, said male or female elements on said chinrest being movable relative to said corresponding male or female elements of said sliding means and said pivoting means on said side wall of said shell.
- This constitution of the guide means allows easy realization and assembly of the chin strap on said shell, while simply allowing to guide the trajectory of the chin relative to the shell without resorting to intricate mechanical interlayers.
- these guide means may also take other forms than that described above and may in particular be replaced by simple sliding means forming, for example, between the shell and the chinrest, a slide connection formed by two elements in support plane or a roller system.
- said guide means comprise a slideway formed on a said lateral surface of the shell, cooperating with a male element, preferably a slider, integral with a branch of said chinrest, and a material axis integral with a side wall of the shell, cooperating with a groove formed on a said branch of the chin.
- the position of said guide means may be inverted so that they comprise at least one male element integral with a said lateral face of the shell, cooperating with a slide formed on a branch of said chin guard, and a groove formed on a said side wall of the shell, cooperating with a material axis integral with a said branch of the chin.
- Such guiding means have the advantage of being very easily achievable by conventional methods of molding and automatic machining of the shell and the chinrest.
- said slide guide means defines a path, preferably not looped, comprising a succession of curves of variable radius, connected together, and that follows said male member of the shell or of said chin guard.
- Such a path defines the trajectory of the chinrest in its simultaneous movements of translation and rotation to allow, when the screen is raised, to pass over it, then to position against the rear wall of the hull of the helmet.
- the shape of said path may be variable depending on the amplitude of the movement that is desired to give the chin and, therefore, it is sufficient to play on the number of curves and their radius, to change the shape of said path while allowing said chin guard to be guided between said closed and open positions.
- said groove of the guide means has a variable depth over its entire length and a shape (a profile) complementary to that of said material axis.
- This configuration of said groove promotes the lateral spacing of the legs of the chinrest relative to the shell, to allow the passage over the screen and the pivoting of the chin guard between said open and closed positions.
- this is facilitated by adequate surfacing of the shell around said material axis.
- said material axis and said groove helmet guiding means according to the invention are substantially aligned with the upper rim of the chin guard.
- said male guide member comprises a locking means against said slide of said chin guard.
- said material axis of the guide means is disposed on the shell, on the side walls thereof at the point tangency between the shell and a plane parallel to the longitudinal plane of symmetry of the helmet.
- the screen of the helmet according to the invention is, in known manner, pivotally mounted relative to to the hull around a clean axis, which allows raising or lowering said screen independently of the chinrest.
- said screen, in said closed position of the chinrest bears against the upper outer rim of the chin guard, in a manner identical to that of a conventional "integral" helmet, but also makes it possible to raise said chin guard and that it passes over said screen to be tilted to the back of the hull in the open position.
- said screen is rotatably mounted relative to the shell around a proper axis such that, when raising said screen, the inner surface thereof is closer to the outer surface of said shell.
- This feature is more particularly interesting and effective when said axis of rotation of the screen is set back relative to said material pivoting axis of the chin guard, in a direction parallel to the longitudinal direction of the helmet and in alignment with said means of rotation. guiding the chin guard.
- said material axis about which the chinrest pivots is constituted by a ball adapted to slide in said groove.
- said guide means are such that said branches of the chin guard have, in said closed and open positions thereof, a first gap E1 with respect to the side walls of said shell, said ball joint being positioned at a first end of said groove of maximum depth. Then, when the passage of said chin guard from the closed position to the open position, and vice versa, said legs of the chin guard deviate from said walls to a distance E2 greater than E1, said ball being then positioned at a second end of said slide minimal depth. This further improves the passage of the chin guard above the screen and pivoting between the two open and closed positions thereof.
- the surfaces, respectively external and internal side walls of said shell and said branches of the chinrest, are in constant support in all positions of the chin with respect to said shell.
- said inner and outer surfaces of the chin and the helmet are treated so as to reduce friction, for example, by a Teflon coating or other material with a low coefficient of friction.
- a closure device of the chinrest in the closed position to ensure a locking thereof and prevent opening movements in case of impact.
- the screen is raised, positioned closest to the hull.
- the helmet further comprises a means of automatic lifting of the screen, able to be triggered during the lifting of said chin guard to move it from said position. closed to said open position.
- the helmet according to the invention is also characterized in that the external profile of the chin strap is adapted to fit in the continuity of the external profile of the shell in said open position of said chin guard, so that that said helmet has on the rear of the hull a substantially continuous profile, devoid of projection or recess, in said open position of the chinrest.
- This feature is particularly important in that, on the one hand, the aerodynamics of the helmet is preserved in the open and closed positions of the chin guard and, on the other hand, greatly improves the safety of the helmet according to the invention compared to the helmets.
- movable chin rest in that it is thus possible to satisfy the rotational acceleration test required by the standards in force.
- the helmet 1 essentially comprises a rigid shell 2 protecting the head of a user from the neck to the front and the sagittal walls of the skull, a rigid chinrest 4 and integral with the shell 2, covering the mandibular arch and the mouth of the user's face and finally a screen 3 adapted to cover the opening formed between the front edge of the shell and the upper edge 43 of the chin guard, said screen being transparent, of toric shape and ensuring a good visibility and a good protection of the user against the external elements (wind, rain, insects).
- Said screen and said chinrest are movable relative to the shell 2 and are fixed on the side walls 2 1 , 2 2 thereof.
- the screen is in known manner rotatable about an axis transverse to said shell (not shown) passing therethrough from one side, materialized on the side walls 2 1 , 2 2 by a rod or cylindrical axis or a circular section cooperating with a shape complementary to said screen.
- the chin guard 4 is movable between two extreme stationary positions corresponding to two possible configurations of use of the helmet; a closed position in which said chin guard is locked on the front of the shell 2 in a helmet configuration called “Integral", and an open position in which the chinrest is positioned at the rear of said shell and against the latter to use the headset in a "Jet" headset configuration.
- the chinrest 4 is fixed on the shell 2 of the helmet by lateral branches 4 1 , 4 2 , respectively attached to the side walls of the shell 2 1 , 2 2 , substantially at the point of tangency between said walls and a parallel vertical plane in the longitudinal plane of symmetry of the helmet Ps.
- the helmet 1 being strictly identical on both sides of said plane Ps, it is shown in the figures only in a side view along the wall 2 1 of the shell.
- the junction of the chin guard 4 on the shell 2 is formed by means of fastening means also constituting guide means 5 1 , 5 2 , 6 1 , 6 2 for the displacement of said chin between said closed and open positons and vice versa in relation to the shell 2 and the screen 3.
- These guide means are formed on each side wall 2 1 , 2 2 of the shell and on each lateral branch of the chin 4 1 , 4 2 , said guide means of the shell and the chinrest being complementary and formed of male elements 5 2 , 6 1 , and females 5 1 , 6 2 .
- Said guide means are adapted to allow a simultaneous displacement movement in translation and in rotation of the chin guard with respect to the shell of the helmet from said closed position to said open position and vice versa.
- each leg 4 1 , 4 2 of said chin guard comprises a horizontal groove 6 2 opening cooperating with a pivot 6 1 formed on each of the side walls of the shell, at said point of tangency between said shell and a said plane vertical parallel to the plane of symmetry Ps of the helmet 1.
- each branch 4 1 , 4 2 also comprises a lug 5 2 projecting on its inner face and cooperating with a guide path formed by a rail 5 1 formed on each side wall 2 1 , 2 2 of the shell.
- the lug may advantageously be formed by molding or else by a cylindrical pin inserted in force in a hole drilled on the branch ( figure 6 ) and the rail 5 1 also formed by molding or milling on the shell 2.
- the groove 6 2 has an inner profile depth and width varying over the entire length of said groove and of shape complementary to that of said pivot 6 1 with which it cooperates, said pivot being, as for him, advantageously constituted by a ball substantially hemispherical on each side wall 2 1 , 2 2 of the hull.
- the legs of the chin guard are secured to the side walls of said shell, at said pivoting pivot, by means of a pin. 7 or a rivet inserted into abutment inside the groove 6 2 and the pivot 6 1 , along the pivot axis formed by said ball and passing through the top thereof, said pin 7 or said rivet advantageously comprising a cylindrical rod of a length at least equal to the maximum depth of said groove and being movable in translation along said pivot axis.
- the assembly of the groove 6 with the ball 2 6 1 using a pin or rivet is a sliding pivot connection on each side wall 2 1, 2 2 of the shell 2 allowing said chinrest to be movable in translation and rotation relative to said shell.
- the rail 5 1 cooperating with said lug 5 2 form a sliding connection between said chin guard and said shell which is complementary to said sliding pivot connection in that it makes it possible to direct the movement of the chin guard between said closed position and said open position thereof and vice versa.
- the rail 5 1 comprises a succession of rectilinear portions non-collinear and non-orthogonal, interconnected by curved portions, in this case substantially circular, to allow smooth sliding of the lug 5 2 branches of the chin rest in said rail.
- the rail can take any other form.
- the lug 5 2 of the legs of the chin strap advantageously comprises, in a preferred embodiment, a locking means (not shown) inside the rail 5 1 .
- Such locking means may in particular be constituted by an end bead forming a hook adapted to bear against an inner wall of the rail. Said pin then forms a slider whose end prevents exit from the rail.
- the rail 5 1 may be formed by a protruding rib on the side walls of the shell, said slider 5 2 branches of the chinrest can then follow said rail by pressing against one of the walls of the ci or alternatively be replaced by a clamp system formed of two small lugs protruding on the inner wall of each leg of the chin, forming jaws clipping force on said rail.
- the helmet according to the invention can be used in a configuration of "Integral" classic helmet.
- the screen 3 of the helmet in its lowered positon, bears against the upper outer edge of the chin guard, which includes a shoulder 4 against 3 wherein the inside surface of the lower edge 3 1 of the screen may come supported when the screen is lowered, said shoulder being, in known manner, covered with a seal 8, for example a lip seal.
- the chin strap 4 of the helmet is tiltable in position open to the rear of the hull 2. This tilting movement is enabled by the guiding means formed respectively on the side walls 2 1 , 2 2 of said shell and the lateral branches of the chin and is shown schematically to the FIGS. 2A to 4C .
- the slider 5 2 of the lateral branches of said chin guard and the ball 6 1 of the side walls of the shell are positioned at a first end of the rail 5 1 and the groove 6 2 respectively.
- the limb 4 1 of the chin guard has a minimum spacing E1, and preferably bears against a side wall of the shell and the ball 6 1 positioned at an end A of the groove 6 2 of maximum depth, c that is, the end closest to said slider 5 2 .
- the user To tilt the chin guard from the closed position to the open position, the user, as shown in FIGS. 3A to 3C , first of all the screen 3, following the arrow F3, said screen then approaching the upper wall of the shell 2.
- the user then operates a pulling force and pushing under the chin, using of the thumb, which causes, at first, a translational movement of the chinrest towards the front of the helmet, in the direction of the arrow F1, guided by a rectilinear sliding of the slider 5 2 inside a first horizontal cross section 5 11 of the rail 5 1 , and a sliding of the groove 6 2 of the chinrest on the ball 6 1 of the side wall 2 1 of the shell 2.
- the slider 5 2 Under the force of traction and push the thumb, the slider 5 2 package follows a second rectilinear portion 5 12, inclined relative to the horizontal, which results in a tilting of the chin guard in the direction of the arrow F4, such that represented in dotted lines at the figure 3A , this rocking of the chinrest 4 being composed of a movement of translation and simultaneous pivoting of the chinrest by sliding and pivoting of the groove 6 2 on the ball 6 1 .
- said groove 6 2 and said ball 6 1 also cause a separation of the lateral arms 4 1, 4 2 relative to the side walls 2 1, 2 2 of the shell to allow the passage of said chin guard above the helmet screen.
- Such locking means may in particular be constituted by a locking notch formed at the end of the rectilinear section 12 of the guide rail 5 1 of the slider 5 2 on each leg of the chin.
- the chin strap then rotates around the ball joints 6 1 of the side walls of the shell, the slider 5 2 of the chin guard sliding in a circular portion 13 of the rail 5 1 of the corresponding side wall 2 1 of the shell, as shown in FIG. Figure 4A , thus making it possible to maintain the maximum spacing E2 of the chin guard 4 with respect to the shell 2 and the screen 3.
- said chinrest 4 is positioned at the rear of the shell 2 and then follows a new movement of forward translation of the helmet and simultaneous rotation around the pivot 6 1 , guided by a new rectilinear portion 14 of the inclined rail 5 1 , the sliding of the cursor in this new rectilinear portion causing a reconciliation of the chinrest to the rear wall 2 3 of the shell so that said chin strap comes to marry the profile of said shell, at the same time as the lateral branch 4 1 of the chinrest are closer to the side wall 2 1 of the shell by sliding the groove 5 2 on the ball 6 1 to its end A of maximum depth.
- the end portion of the rail 5 1 on each of the side walls of the shell has a straight horizontal portion 15 , in which abuts the slider 5 2 branches when the chinrest has reached its open position in which it is positioned at the rear, against the wall, and in the continuity of the profile of the shell 2, which profile may comprise, as shown in FIG. figure 5 , a spoiler 9 against which comes to lock the lower edge of the chin guard in the open position.
- the return of the chin guard, from the open position to the closed position, is then carried out in a reverse trajectory to that described above, guided by sliding of the slider 5 2 and the groove 6 2 formed on each of the lateral branches of the chin guard , respectively in said rail 5 1 and said ball 6 1 formed on the side walls of the hull.
- the own axis of rotation of the screen 3 which is not shown, is advantageously positioned recessed with respect to said ball 6 1 on each of the side walls 2 1 , 2 2 towards the rear of the hull. This allows, when raising said screen, that the inner surface thereof is closer to the outer surface of the shell, thus reducing the necessary movement of the chin guard relative to the screen and the shell and, therefore, to reduce the length of the groove 6 2 formed on each of the lateral branches of the chin.
- the surface of said walls is advantageously designed to match the internal profile of said branches of the chinrest in all positions thereof relative to the hull
- said screen also comprises, at its axis of rotation, an automatic lifting means.

On connaît depuis longtemps des casques de protection dits de type "Intégral", constitués d'une coque protégeant l'ensemble du crâne ainsi que la portion faciale du menton, et d'un écran transparent, généralement monté pivotant sur les parois latérales de la coque, et permettant de recouvrir et protéger la portion du visage située au niveau des yeux de l'utilisateur.Protective helmets known as "Integral" have long been known, consisting of a shell protecting the whole of the skull as well as the facial portion of the chin, and a transparent screen, generally pivotally mounted on the side walls of the body. shell, and to cover and protect the portion of the face located at the level of the eyes of the user.
En termes de sécurité, les casques intégraux s'avèrent être les plus satisfaisant. Néanmoins, la protection mentonnière de ces casques entraîne un manque de liberté pendant l'utilisation, en ce qu'il est impossible de dégager le visage afin de discuter, par exemple, sans retirer le casque entièrement lorsque l'on est à l'arrêt, ou que la chaleur rend le port d'un tel casque "Intégral" pénible pour le motocycliste qui peut être amené à suer à l'intérieur dudit casque. En outre, les personnes équipées de lunettes, ne peuvent mettre ou enlever un casque "Intégral" sans retirer au préalable leurs dites lunettes, ce qui, là aussi, est inconfortable.In terms of safety, the full-face helmets prove to be the most satisfactory. Nevertheless, the chin protection of these helmets causes a lack of freedom during use, in that it is impossible to clear the face to discuss, for example, without removing the helmet completely when one is stopped , or that the heat makes the wearing of such a headphone "Integral" painful for the motorcyclist who can be sweated inside said helmet. In addition, people with glasses, can not put on or remove a headset "Integral" without removing beforehand their said glasses, which, again, is uncomfortable.
Aussi, pour pallier ces problèmes, ont été développés des casques munis d'une mentonnière mobile par rapport au reste de la coque, permettant ainsi dans une première position, dite "fermée", de la mentonnière, d'utiliser le casque dans une configuration de casque "Intégral" et, dans une seconde position, dite "ouverte", de dégager le visage du motocycliste tout en gardant le casque sur le crâne.Also, to overcome these problems, have been developed helmets with a chinrest mobile relative to the rest of the shell, thus allowing in a first position, called "closed", the chin strap, to use the helmet in a configuration "Integral" helmet and, in a second position, called "open", to clear the face of the motorcyclist while keeping the helmet on the skull.
Parmi ces casques à mentonnière mobile, différentes solutions technologiques ont également été développées, parmi lesquelles on peut notamment distinguer :
- 1- les casques comportant un écran et une mentonnière qui peuvent être relevés et positionnés au niveau de la zone frontale de la coque, dans le prolongement du sommet du casque, dégageant ainsi le visage de l'utilisateur pour faciliter la mise en place du casque sur la tête, ou encore rouler à visage découvert lorsqu'il fait chaud. De tels casques sont notamment décrits dans les brevets
EP 0895726 A1 EP 1183957 A1 EP 0258 552 A1
Ces casques n'autorisent pas de circuler avec la mentonnière ouverte en complète sécurité. En effet, en position ouverte, le poids de la mentonnière située en position frontale, provoque un balourd important du casque, amplifié par la prise au vent que représente la mentonnière au-dessus de la tête du motocycliste. De plus, en cas de chute, il existe des risques graves de lésions en raison de la prise importante offerte par la mentonnière du casque en position ouverte aux éléments extérieurs. - 2- une autre solution proposée consiste en un casque dont la mentonnière est scindée en deux parties mobiles latéralement par rapport à la coque, tel que décrit dans
EP 0433182 A1
Cette solution présente néanmoins l'inconvénient important d'affaiblir de façon rédhibitoire la résistance du casque au niveau de la jonction des deux parties de la mentonnière en position fermée, ce qui, en cas de choc, peut faciliter les enfoncements et/ou la rupture du casque au niveau de cette dite jonction et donc des traumatismes faciaux très importants. - 3- une autre solution connue consiste à proposer des casques tels que décrits dans les demandes de brevets
EP 0993784 A1 EP 1120419 A1
- 1- the helmets comprising a screen and a chinrest that can be raised and positioned at the frontal zone of the shell, in the extension of the top of the helmet, thus clearing the face of the user to facilitate the introduction of the helmet on the head, or roll open face when it's hot. Such helmets are in particular described in the patents
EP 0895726 A1 EP 1183957 A1 EP 0258 552 A1
These helmets do not allow to circulate with the open chin guard in complete safety. Indeed, in the open position, the weight of the chinrest located in the frontal position, causes significant unbalance of the helmet, amplified by taking wind that represents the chinrest above the head of the motorcyclist. In addition, in the event of a fall, there is a serious risk of injury due to the large catch provided by the chin strap of the helmet in the open position to the external elements. - 2- another proposed solution consists of a helmet whose chin strap is divided into two parts movable laterally relative to the shell, as described in
EP 0433182 A1
This solution nevertheless has the important disadvantage of weakening unacceptably the strength of the helmet at the junction of the two parts of the chin guard in the closed position, which, in case of impact, can facilitate the depressions and / or breakage from headphones to level of this junction and therefore very important facial traumas. - 3- another known solution is to propose helmets as described in the patent applications
EP 0993784 A1 EP 1120419 A1
Cette solution, si elle résout en partie les problèmes des casques à mentonnière mobile précédemment décrits, en soulève d'autres induits par le positionnement de l'écran à l'intérieur de la mentonnière dans la position fermée de celle-ci.This solution, if it partially solves the problems of movable chinrest helmets previously described, raises others induced by the positioning of the screen inside the chin guard in the closed position thereof.
En effet, il résulte de cette position de l'écran un manque d'étanchéité au niveau de la jonction écran/mentonnière, pouvant causer des infiltrations d'air et d'eau ainsi qu'une augmentation des vibration de l'écran en circulation perturbant le motocycliste lors de la conduite et diminuant la sécurité procurée par le casque en raison du manque d'appui de l'écran sur la mentonnière qui favorise l'enfoncement de celui-ci en cas d'impact.Indeed, it results from this screen position a lack of tightness at the screen / chin junction, can cause infiltration of air and water and an increase in vibration of the screen in circulation disturbing the motorcyclist while driving and decreasing the safety provided by the helmet due to the lack of support of the screen on the chinrest which promotes the depression of it in case of impact.
Selon une autre caractéristique des casques du type décrit dans
On connaît enfin des casques tels que décrits dans
Contrairement aux différentes catégories de casques décrites précédemment, la mentonnière du casque décrit dans
Un but de la présente invention est de fournir un casque à mentonnière mobile qui permette, dans la position fermée de la mentonnière, de présenter le même degré de sécurité et d'étanchéité, entre l'écran et la mentonnière, qu'un casque "Intégral" classique.An object of the present invention is to provide a movable chin strap which allows, in the closed position of the chinrest, to have the same degree of safety and sealing, between the screen and the chinrest, a helmet " Integral "classic.
Un autre but de la présente invention est de fournir un casque qui permette également un dégagement complet de la zone faciale du casque et un escamotage de la mentonnière dans la position ouverte de celle-ci, afin de permettre une utilisation du casque en configuration de casque de type "Jet", c'est-à-dire dépourvu de mentonnière, sans risque pour l'utilisateur en cas de chute ou d'impact, comme cela est le cas avec les casque décrit dans le document
L'invention se propose également de fournir un casque à mentonnière mobile qui remplisse toutes les conditions de protection exigées par les normes en vigueur et qui permette un passage de la position fermée à la position ouverte de la mentonnière, et vice et versa, à l'aide d'une seule main.The invention also proposes to provide a movable chin-strap helmet that fulfills all the protection requirements required by the standards in force and that allows a transition from the closed position to the open position of the chin guard, and vice versa, to the help with one hand.
Un autre but de l'invention est de fournir un casque tel que décrit ci-dessus, dont la constitution est simple et dont la forme soit aérodynamiquement satisfaisante quelque soit la position ouverte ou fermée de la mentonnière.Another object of the invention is to provide a helmet as described above, whose constitution is simple and whose shape is aerodynamically satisfactory whatever the open or closed position of the chinrest.
Ces différents buts sont atteints grâce à un casque de protection, en particulier pour le motocyclisme, comportant une coque sur les parois latérales de laquelle sont fixés un écran apte à pivoter par rapport à ladite coque et une mentonnière mobile apte à être relevée par-dessus ledit écran et basculée vers l'arrière au-delà du sommet de ladite coque, depuis une position fermée jusqu'à une position ouverte, ledit casque étant caractérisé en ce que, dans ladite position fermée, ledit écran est apte à reposer contre un rebord supérieur externe de ladite mentonnière et en ce que ladite coque et ladite mentonnière comportent des moyens de guidage complémentaires tels que la trajectoire de ladite mentonnière entre ladite position fermée et ladite position ouverte, soit une trajectoire non entièrement circulaire suivant laquelle ladite mentonnière s'écarte tout d'abord de ladite coque puis est relevée et basculée par-dessus ledit écran, et enfin se rapproche de ladite coque à l'arrière de celle-ci.These various goals are achieved through a protective helmet, particularly for motorcycling, having a shell on the side walls of which are fixed a screen pivotable relative to said shell and a movable chinrest able to be raised over said screen and tilted back beyond the top of said shell, from a closed position to an open position, said helmet being characterized in that, in said closed position, said screen is adapted to rest against a rim outer upper of said chin guard and in that said shell and said chin guard comprise complementary guide means such as the trajectory of said chin guard between said closed position and said open position, ie a non-circular path according to which said chin guard deviates all first of said shell and is raised and tilted over said screen, and finally gets closer said shell at the rear thereof.
On comprend que ladite coque du casque est destinée à recouvrir le crâne d'un utilisateur afin de protéger celui-ci contre les chocs et que, dans ladite position fermée de la mentonnière, celle-ci est positionnée à l'avant de ladite coque et recouvre l'arc mandibulaire du visage de l'utilisateur pour protéger cette partie du visage en cas de chute.It is understood that said shell of the helmet is intended to cover the skull of a user to protect it from shocks and that, in said closed position of the chin guard, it is positioned in front of said shell and covers the mandibular arch of the user's face to protect this part of the face in the event of a fall.
Ainsi, le casque selon l'invention est particulièrement avantageux en ce que, dans la position fermée de la mentonnière, l'écran est apte à venir en appui contre le rebord supérieur externe de la mentonnière, comme cela est le cas avec les casques intégraux classiques. Ceci permet, contrairement aux casques proposés dans les documents
En outre, le casque selon l'invention permet également de dégager entièrement le visage de l'utilisateur, de par sa mentonnière mobile dont le déplacement est guidé, de manière à pouvoir utiliser le casque en configuration "Jet" sans risque de déséquilibre de la tête, comme cela est le cas avec des casques à mentonnière relevables tels que décrits dans les documents
Pour ce faire, les moyens de guidage confèrent un déplacement complexe de ladite mentonnière, selon lequel celle-ci s'écarte dans un premier temps de la coque vers l'avant dans une direction longitudinale, ainsi que sur les cotés dans une direction transversale, pour passer au-dessus de l'écran puis, ensuite, pivote au-dessus du sommet de la coque vers l'arrière, puis enfin se rapproche de ladite coque dans lesdites directions longitudinales et transversales.To do this, the guiding means provide a complex displacement of said chin guard, according to which the latter departs in a first step from the shell forward in a longitudinal direction, as well as on the sides in a transverse direction, to pass over the screen then, then pivots above the top of the hull aft, then finally approaches the hull in said longitudinal and transverse directions.
Ainsi la trajectoire suivie par la mentonnière est non circulaire mais s'effectue, également, simultanément dans deux directions orthogonales, ce qui permet de passer au-dessus de l'écran depuis ladite position fermée, dans laquelle la mentonnière est en retrait derrière l'écran, jusqu'à ladite position ouverte en appui contre la partie occipitale de la coque du casque.Thus the trajectory followed by the chinrest is non-circular but is also performed simultaneously in two orthogonal directions, which allows to pass over the screen from said closed position, in which the chinrest is recessed behind the screen, to said open position bearing against the occipital portion of the helmet shell.
De façon avantageuse, lesdits moyens de guidage de la coque et de la mentonnière comportent respectivement des moyens de coulissement et des moyens de pivotement, agencés de manière à permettre des mouvements simultanés de translation et de rotation de ladite mentonnière par rapport à ladite coque et audit écran, entre ladite position fermée et ladite position ouverte de ladite mentonnière.Advantageously, said guiding means of the shell and the chin strap respectively comprise sliding means and pivoting means, arranged so as to allow simultaneous movements of translation and rotation of said chin guard with respect to said shell and said screen, between said closed position and said open position of said chin guard.
De tels moyens de guidage autorisent un déplacement combiné en translation et rotation de la mentonnière, sans à coup ni blocage, entre les positions ouverte et fermée de ladite mentonnière, et vice et versa, ce qui permet à l'utilisateur d'effectuer ledit déplacement de façon aisée et d'une seule main.Such guiding means allow a combined movement in translation and rotation of the chin guard, without any hitting or blocking, between the open and closed positions of said chin guard, and vice versa, which allows the user to perform said movement easily and with one hand.
Toutefois, dans une variante de réalisation, on pourra prévoir que les moyens de guidage permettent également de faire adopter à la mentonnière une position stationnaire intermédiaire entre ses positions "fermée" et "ouverte". Une telle position intermédiaire pourra par exemple être une position de maintien de la mentonnière en position frontale sur l'avant de la coque du casque, cette position permettant par exemple à l'utilisateur, de "chausser" son casque sans avoir à retirer ses lunettes ou tout en continuant à parler avec un interlocuteur.However, in an alternative embodiment, it can be provided that the guide means also allow to adopt the chin bar stationary intermediate position between its "closed" and "open" positions. Such an intermediate position may for example be a holding position of the chinrest in the frontal position on the front of the helmet shell, this position allowing the user, for example, to "put on" his helmet without having to remove his glasses or while continuing to talk with someone.
Selon une autre caractéristique de l'invention, lesdits moyens de coulissement et lesdits moyens de pivotement comportent au moins un élément mâle sur une paroi latérale de ladite coque ou sur ladite mentonnière, coopérant avec au moins un élément femelle sur ladite mentonnière ou sur une paroi latérale de ladite coque respectivement, lesdits éléments mâles ou femelles sur ladite mentonnière étant mobiles par rapport auxdits éléments mâles ou femelles correspondants desdits moyens de coulissement et dits moyens de pivotement sur une dite paroi latérale de ladite coque.According to another characteristic of the invention, said sliding means and said pivoting means comprise at least one male element on a side wall of said shell or on said chinrest, cooperating with at least one female element on said chinrest or on a wall lateral of said shell respectively, said male or female elements on said chinrest being movable relative to said corresponding male or female elements of said sliding means and said pivoting means on said side wall of said shell.
Cette constitution des moyens de guidage permet une réalisation et un montage facilités de la mentonnière sur ladite coque, tout en permettant simplement de guider la trajectoire de la mentonnière par rapport à la coque sans avoir recours à des dispositifs mécaniques intercalaires complexes.This constitution of the guide means allows easy realization and assembly of the chin strap on said shell, while simply allowing to guide the trajectory of the chin relative to the shell without resorting to intricate mechanical interlayers.
Toutefois, ces moyens de guidage peuvent également prendre d'autre forme que celle décrite ci-avant et peuvent notamment être remplacés par de simples moyens de glissement formant, par exemple, entre la coque et la mentonnière, une liaison glissière constituée par deux éléments en appui-plan ou encore un système à galet.However, these guide means may also take other forms than that described above and may in particular be replaced by simple sliding means forming, for example, between the shell and the chinrest, a slide connection formed by two elements in support plane or a roller system.
Dans un mode préféré de réalisation, lesdits moyens de guidage comportent une glissière formée sur une dite surface latérale de la coque, coopérant avec un élément mâle, de préférence un curseur, solidaire d'une branche de ladite mentonnière, et un axe matériel solidaire d'une paroi latérale de la coque, coopérant avec une rainure formée sur une dite branche de la mentonnière.In a preferred embodiment, said guide means comprise a slideway formed on a said lateral surface of the shell, cooperating with a male element, preferably a slider, integral with a branch of said chinrest, and a material axis integral with a side wall of the shell, cooperating with a groove formed on a said branch of the chin.
En variante, la position desdits moyens de guidage peut être inversée de telle sorte qu'ils comportent au moins un élément mâle solidaire d'une dite face latérale de la coque, coopérant avec une glissière formée sur une branche de ladite mentonnière, et une rainure formée sur une dite paroi latérale de la coque, coopérant avec un axe matériel solidaire d'une dite branche de la mentonnière.Alternatively, the position of said guide means may be inverted so that they comprise at least one male element integral with a said lateral face of the shell, cooperating with a slide formed on a branch of said chin guard, and a groove formed on a said side wall of the shell, cooperating with a material axis integral with a said branch of the chin.
De tels moyens de guidage présentent l'avantage d'être très facilement réalisables par des procédés classiques de moulage et d'usinage automatiques de la coque et de la mentonnière.Such guiding means have the advantage of being very easily achievable by conventional methods of molding and automatic machining of the shell and the chinrest.
Conformément à une autre caractéristique préférée de l'invention, ladite glissière des moyens de guidage définit un chemin, de préférence non bouclé, comprenant une succession de courbes de rayons variables, raccordées entre elles, et que suit ledit élément mâle de la coque ou de ladite mentonnière.According to another preferred feature of the invention, said slide guide means defines a path, preferably not looped, comprising a succession of curves of variable radius, connected together, and that follows said male member of the shell or of said chin guard.
Un tel chemin définit la trajectoire de la mentonnière dans ses mouvements simultanés de translation et de rotation pour permettre, lorsque l'écran est relevé, de passer au-dessus de celui-ci, puis de se positionner contre la paroi arrière de la coque du casque.Such a path defines the trajectory of the chinrest in its simultaneous movements of translation and rotation to allow, when the screen is raised, to pass over it, then to position against the rear wall of the hull of the helmet.
La forme dudit chemin peut être variable en fonction de l'amplitude du mouvement que l'on souhaite donner à la mentonnière et, de ce fait, il suffit de jouer sur le nombre de courbes et leur rayon, pour modifier la forme dudit chemin tout en permettant le guidage de ladite mentonnière entre ses dites positions fermée et ouverte.The shape of said path may be variable depending on the amplitude of the movement that is desired to give the chin and, therefore, it is sufficient to play on the number of curves and their radius, to change the shape of said path while allowing said chin guard to be guided between said closed and open positions.
Selon une autre caractéristique avantageuse de l'invention, ladite rainure des moyens de guidage présente une profondeur variable sur toute sa longueur ainsi qu'une forme (un profil) complémentaire de celle dudit axe matériel.According to another advantageous characteristic of the invention, said groove of the guide means has a variable depth over its entire length and a shape (a profile) complementary to that of said material axis.
Cette configuration de ladite rainure favorise l'écartement latéral des branches de la mentonnière par rapport à la coque, pour autoriser le passage au-dessus de l'écran et le pivotement de la mentonnière entre ses dites positions ouverte et fermée. Toutefois, on pourrait également envisager que ceci soit facilité par un surfaçage adéquat de la coque autour dudit axe matériel.This configuration of said groove promotes the lateral spacing of the legs of the chinrest relative to the shell, to allow the passage over the screen and the pivoting of the chin guard between said open and closed positions. However, it could also be envisaged that this is facilitated by adequate surfacing of the shell around said material axis.
De préférence, ledit axe matériel et ladite rainure des moyens de guidage du casque selon l'invention, sont sensiblement alignés avec le rebord supérieur de la mentonnière.Preferably, said material axis and said groove helmet guiding means according to the invention are substantially aligned with the upper rim of the chin guard.
Ainsi, on peut réaliser une dite mentonnière qui soit la plus compacte possible et dont l'amplitude de déplacement soit telle que ladite mentonnière épouse au plus proche la forme de la coque du casque entre ses positions ouverte et fermée.Thus, one can achieve a said chinrest which is as compact as possible and whose range of motion is such that said chin strap close to the shape of the shell of the helmet between its open and closed positions.
Dans un mode de réalisation préférée, ledit élément mâle de guidage comporte un moyen de blocage contre ladite glissière de ladite mentonnière. Cette dernière caractéristique permet avantageusement de prévenir les mouvements latéraux de la mentonnière et force un contact permanent entre celle-ci et la coque afin de prévenir les vibrations lors de la conduite.In a preferred embodiment, said male guide member comprises a locking means against said slide of said chin guard. This last feature advantageously prevents lateral movements of the chin and forces a permanent contact between the latter and the shell to prevent vibration during driving.
Pour obtenir un pivotement et un glissement le plus fluides possible en limitant au maximum les frottements bloquants de la mentonnière sur la coque, ledit axe matériel des moyens de guidage est disposé sur la coque, sur les parois latérales de celle-ci au niveau du point de tangence entre la coque et un plan parallèle au plan de symétrie longitudinale du casque.To obtain the most fluid pivoting and sliding possible by limiting as much as possible the blocking friction of the chinrest on the shell, said material axis of the guide means is disposed on the shell, on the side walls thereof at the point tangency between the shell and a plane parallel to the longitudinal plane of symmetry of the helmet.
En outre, afin d'autoriser la plus grande latitude d'utilisation du casque à son utilisateur, indépendamment de la position ouverte ou fermée de la mentonnière, l'écran du casque selon l'invention est, de façon connue, monté pivotant par rapport à la coque autour d'un axe propre, ce qui permet de lever ou abaisser ledit écran indépendamment de la mentonnière. Toutefois, il convient que ledit écran, dans ladite position fermée de la mentonnière, vienne en appui contre le rebord supérieur externe de la mentonnière, de façon identique à celle d'un casque "Intégral" classique, mais permette également de relever ladite mentonnière et que celle-ci passe par-dessus ledit écran pour pouvoir être basculée à l'arrière de la coque dans la position ouverte.In addition, in order to allow the greatest latitude of use of the helmet to its user, regardless of the open or closed position of the chinrest, the screen of the helmet according to the invention is, in known manner, pivotally mounted relative to to the hull around a clean axis, which allows raising or lowering said screen independently of the chinrest. However, it is appropriate that said screen, in said closed position of the chinrest, bears against the upper outer rim of the chin guard, in a manner identical to that of a conventional "integral" helmet, but also makes it possible to raise said chin guard and that it passes over said screen to be tilted to the back of the hull in the open position.
C'est pourquoi, selon une autre caractéristique avantageuse de l'invention, ledit écran est monté mobile en rotation par rapport à la coque autour d'un axe propre tel que, lors du relevage dudit écran, la surface interne de celui-ci se rapproche de la surface externe de ladite coque.This is why, according to another advantageous characteristic of the invention, said screen is rotatably mounted relative to the shell around a proper axis such that, when raising said screen, the inner surface thereof is closer to the outer surface of said shell.
Cette caractéristique est plus particulièrement intéressante et effective lorsque ledit axe de rotation de l'écran est placé en retrait par rapport audit axe matériel de pivotement de la mentonnière, dans une direction parallèle à la direction longitudinale du casque et dans l'alignement desdits moyens de guidage de la mentonnière.This feature is more particularly interesting and effective when said axis of rotation of the screen is set back relative to said material pivoting axis of the chin guard, in a direction parallel to the longitudinal direction of the helmet and in alignment with said means of rotation. guiding the chin guard.
Selon une autre caractéristique préférée, ledit axe matériel autour duquel pivote la mentonnière, est constitué par une rotule apte à glisser dans ladite rainure.According to another preferred feature, said material axis about which the chinrest pivots, is constituted by a ball adapted to slide in said groove.
Une telle rotule permet ainsi de glisser plus facilement dans la rainure et de réaliser un ajustement de l'écartement de la mentonnière par rapport à la coque du casque lors du pivotement. En effet, selon un mode de réalisation préféré, lesdits moyens de guidage sont tels que lesdites branches de la mentonnière présentent, dans lesdites positions fermée et ouverte de celle-ci, un premier écartement E1 par rapport aux parois latérales de ladite coque, ladite rotule étant positionnée au niveau d'une première extrémité de ladite rainure de profondeur maximale. Ensuite, lors du passage de ladite mentonnière de la position fermée à la position ouverture, et inversement, lesdites branches de la mentonnière s'écartent desdites parois jusqu'à un écartement E2 supérieur à E1, ladite rotule étant alors positionnée à une seconde extrémité de ladite coulisse de profondeur minimale. Ceci permet d'améliorer encore le passage de la mentonnière au-dessus de l'écran et le pivotement entre les deux positions ouverte et fermée de celle-ci.Such a ball thus makes it easier to slide in the groove and to make an adjustment of the spacing of the chin with respect to the shell of the helmet during pivoting. Indeed, according to a preferred embodiment, said guide means are such that said branches of the chin guard have, in said closed and open positions thereof, a first gap E1 with respect to the side walls of said shell, said ball joint being positioned at a first end of said groove of maximum depth. Then, when the passage of said chin guard from the closed position to the open position, and vice versa, said legs of the chin guard deviate from said walls to a distance E2 greater than E1, said ball being then positioned at a second end of said slide minimal depth. This further improves the passage of the chin guard above the screen and pivoting between the two open and closed positions thereof.
Avantageusement, les surfaces, respectivement externe et interne des parois latérales de ladite coque et desdites branches de la mentonnière, sont en appui constant dans toutes les positions de la mentonnière par rapport à ladite coque.Advantageously, the surfaces, respectively external and internal side walls of said shell and said branches of the chinrest, are in constant support in all positions of the chin with respect to said shell.
Ceci permet d'éviter les vibrations ainsi que les mouvement de torsion de la mentonnière par rapport à la coque et améliore encore le confort de l'utilisateur. En outre, on peut également prévoir que lesdites surfaces internes et externes de la mentonnière et du casque sont traitées de manière à diminuer les frottements, par exemple, par un revêtement en téflon ou autre matière à faible coefficient de frottement.This avoids vibration and torsional movement of the chinrest relative to the shell and further improves the comfort of the user. In addition, it can also be provided that said inner and outer surfaces of the chin and the helmet are treated so as to reduce friction, for example, by a Teflon coating or other material with a low coefficient of friction.
Selon une autre caractéristique de l'invention, on prévoit également un dispositif de fermeture de la mentonnière en position fermée afin d'assurer un verrouillage de celle-ci et éviter les mouvements d'ouverture en cas d'impact.According to another characteristic of the invention, there is also provided a closure device of the chinrest in the closed position to ensure a locking thereof and prevent opening movements in case of impact.
De plus, afin de faciliter un passage rapide de la mentonnière entre lesdites positions ouverte et fermée, il est préférable que l'écran soit relevé, positionné au plus proche de la coque.In addition, to facilitate rapid passage of the chin guard between said open and closed positions, it is preferable that the screen is raised, positioned closest to the hull.
C'est pourquoi, selon une autre caractéristique de l'invention, le casque comporte, en outre, un moyen de relevage automatique de l'écran, apte à être déclenché lors du relevage de ladite mentonnière pour faire passer celle-ci de ladite position fermée à ladite position ouverte.This is why, according to another characteristic of the invention, the helmet further comprises a means of automatic lifting of the screen, able to be triggered during the lifting of said chin guard to move it from said position. closed to said open position.
D'une façon avantageuse, le casque selon l'invention est également caractérisé en ce que le profil externe de la mentonnière est adapté pour s'inscrire dans la continuité du profil externe de la coque dans ladite position ouverte de ladite mentonnière, de telle sorte que ledit casque présente sur l'arrière de la coque un profil sensiblement continu, dépourvu de saillie ou décrochement, dans ladite positon ouverte de la mentonnière. Cette caractéristique est notamment importante en ce que, d'une part, l'aérodynamisme du casque est préservée dans les positons ouverte et fermée de la mentonnière et, d'autre part, améliore grandement la sécurité du casque selon l'invention comparativement aux casques à mentonnière mobile connus, en ce qu'il est ainsi possible de satisfaire au test d'accélération rotationnelle exigé par les normes en vigueur.Advantageously, the helmet according to the invention is also characterized in that the external profile of the chin strap is adapted to fit in the continuity of the external profile of the shell in said open position of said chin guard, so that that said helmet has on the rear of the hull a substantially continuous profile, devoid of projection or recess, in said open position of the chinrest. This feature is particularly important in that, on the one hand, the aerodynamics of the helmet is preserved in the open and closed positions of the chin guard and, on the other hand, greatly improves the safety of the helmet according to the invention compared to the helmets. movable chin rest, in that it is thus possible to satisfy the rotational acceleration test required by the standards in force.

En référence tout d'abord aux
Ledit écran et ladite mentonnière sont mobiles par rapport à la coque 2 et sont fixés sur les parois latérales 21, 22 de celle-ci.Said screen and said chinrest are movable relative to the
L'écran est de façon connue mobile en rotation autour d'un axe transversal à ladite coque (non représenté) traversant celle-ci de part en part, matérialisé sur les parois latérales 21, 22 par une tige ou axe cylindrique ou encore un tronçon circulaire coopérant avec une forme complémentaire dudit écran.The screen is in known manner rotatable about an axis transverse to said shell (not shown) passing therethrough from one side, materialized on the
Conformément à l'invention, la mentonnière 4 est mobile entre deux positions stationnaires extrêmes correspondant à deux configurations d'utilisation possibles du casque ; une position fermée dans laquelle ladite mentonnière est bloquée sur l'avant de la coque 2 dans une configuration de casque dit "Intégral", et une position ouverte dans laquelle la mentonnière est positionnée à l'arrière de ladite coque et contre celle-ci permettant d'utiliser le casque dans une configuration de type casque « Jet ».According to the invention, the
La mentonnière 4 est fixée sur la coque 2 du casque par des branches latérales 41, 42, attachées respectivement aux parois latérales de la coque 21, 22, sensiblement au niveau du point de tangence entre lesdites parois et un plan vertical parallèle au plan longitudinal de symétrie du casque Ps.The
Le casque 1 étant rigoureusement identique de part et d'autre dudit plan Ps, celui-ci n'est représenté sur les figures qu'en une vue de côté selon la paroi 21 de la coque.The
Selon l'invention, la jonction de la mentonnière 4 sur la coque 2 est réalisée par l'intermédiaire de moyens de fixation constituant également des moyens de guidage 51, 52, 61, 62 permettant le déplacement de ladite mentonnière entre ses dites positons fermée et ouverte et vice et versa par rapport à la coque 2 et l'écran 3.According to the invention, the junction of the
Ces moyens de guidage sont formés sur chaque paroi latérale 21, 22 de la coque ainsi que sur chaque branche latérale de la mentonnière 41, 42, lesdits moyens de guidage de la coque et de la mentonnière étant complémentaires et formés d'éléments mâles 52, 61, et femelles 51, 62.These guide means are formed on each
Lesdits moyens de guidage sont adaptés pour permettre un mouvement de déplacement simultané en translation et en rotation de la mentonnière par rapport à la coque du casque depuis ladite positon fermée jusqu'à ladite position ouverte et vice et versa.Said guide means are adapted to allow a simultaneous displacement movement in translation and in rotation of the chin guard with respect to the shell of the helmet from said closed position to said open position and vice versa.
A cet effet, chaque branche 41, 42 de ladite mentonnière comporte une rainure horizontale 62 débouchante coopérant avec un pivot 61 formé sur chacune des parois latérales de la coque, au niveau dudit point de tangence entre ladite coque et un dit plan vertical parallèle au plan de symétrie Ps du casque 1.For this purpose, each
En outre, chaque branche 41, 42 comporte également un ergot 52 faisant saillie sur sa face interne et coopérant avec un chemin de guidage constitué par un rail 51 formé sur chaque paroi latérale 21, 22 de la coque. L'ergot peut avantageusement être formé par moulage ou encore par un goupillon cylindrique inséré en force dans un trou percé sur la branche (
Selon une caractéristique préférée de l'invention, la rainure 62 présente un profil interne de profondeur et de largeur variables sur toute la longueur de ladite rainure, et de forme complémentaire de celle dudit pivot 61 avec lequel elle coopère, ledit pivot étant, quant à lui, avantageusement constitué par une rotule sensiblement hémisphérique sur chaque paroi latérale 21, 22 de la coque.According to a preferred feature of the invention, the groove 6 2 has an inner profile depth and width varying over the entire length of said groove and of shape complementary to that of said pivot 6 1 with which it cooperates, said pivot being, as for him, advantageously constituted by a ball substantially hemispherical on each
De plus, afin d'éviter tout désengagement de ladite rotule hors de ladite rainure de la mentonnière, on solidarise les branches de la mentonnière aux parois latérales de ladite coque, au niveau de ladite rotule de pivotement, par l'intermédiaire d'une goupille 7 ou d'un rivet introduit en butée à l'intérieur de la rainure 62 et du pivot 61, selon l'axe de pivotement formé par ladite rotule et passant par le sommet de celle-ci, ladite goupille 7 ou ledit rivet comportant avantageusement une tige cylindrique d'une longueur au moins égale à la profondeur maximale de ladite rainure et étant mobile en translation le long dudit axe de pivotement.In addition, in order to prevent any disengagement of said patella from said groove of the chin guard, the legs of the chin guard are secured to the side walls of said shell, at said pivoting pivot, by means of a pin. 7 or a rivet inserted into abutment inside the groove 6 2 and the pivot 6 1 , along the pivot axis formed by said ball and passing through the top thereof, said
Ainsi, l'assemblage de la rainure 62 avec la rotule 61 à l'aide d'une goupille ou d'un rivet, constitue une liaison pivot glissant sur chaque paroi latérale 21, 22 de la coque 2 permettant à ladite mentonnière d'être mobile en translation et en rotation par rapport à ladite coque.Thus, the assembly of the groove 6 with the ball 2 6 1 using a pin or rivet, is a sliding pivot connection on each
En complément de cette liaison pivot glissant, le rail 51 coopérant avec ledit ergot 52 forment une liaison glissière entre ladite mentonnière et ladite coque qui est complémentaire de ladite liaison pivot glissant en ce qu'elle permet de diriger le mouvement de la mentonnière entre ladite position fermée et ladite position ouverte de celle-ci et vice et versa.In addition to this sliding pivot connection, the rail 5 1 cooperating with said lug 5 2 form a sliding connection between said chin guard and said shell which is complementary to said sliding pivot connection in that it makes it possible to direct the movement of the chin guard between said closed position and said open position thereof and vice versa.
Comme représenté aux
Afin d'éviter les vibrations néfastes de la mentonnière 4 ainsi que les mouvements de ballant de celle-ci dans une direction transversale au parois latérales de la coque du casque 1, l'ergot 52 des branches de la mentonnière comporte avantageusement, dans un mode de réalisation préféré, un moyen de blocage (non représenté) à l'intérieur du rail 51. Un tel moyen de blocage peut, notamment, être constitué par un bourrelet d'extrémité formant un crochet apte à venir en appui contre une paroi interne du rail. Ledit ergot forme alors un curseur dont l'extrémité empêche la sortie hors du rail.In order to avoid the harmful vibrations of the
Dans une variante de réalisation non représentée, le rail 51 peut être formé par une nervure saillante sur les parois latérales de la coque, ledit curseur 52 des branches de la mentonnière pouvant alors suivre ledit rail par appui contre une des parois de celui-ci ou encore être remplacé par un système de pince formé de deux petits ergots saillants sur la paroi intérieure de chaque branche de la mentonnière, formant des mâchoires clipsables en force sur ledit rail.In an alternative embodiment not shown, the rail 5 1 may be formed by a protruding rib on the side walls of the shell, said slider 5 2 branches of the chinrest can then follow said rail by pressing against one of the walls of the ci or alternatively be replaced by a clamp system formed of two small lugs protruding on the inner wall of each leg of the chin, forming jaws clipping force on said rail.
On peut, de même, envisager d'inverser le positionnement relatif de la rotule 61 et de la rainure 62 en formant ladite rotule sur la paroi interne de chacune des branches et la dite rainure sur les parois latérales de la coque.One can, likewise, consider reversing the relative positioning of the ball 6 1 and the groove 6 2 forming said ball on the inner wall of each of the branches and said groove on the side walls of the shell.
Dans ladite position fermée de la mentonnière, le casque selon l'invention, peut être utilisé dans une configuration de casque "Intégral" classique. Ainsi, tel que représenté aux
Afin d'utiliser le casque selon l'invention dans une configuration de type casque " Jet ", la mentonnière 4 du casque est basculable en position ouverte vers l'arrière de la coque 2. Ce mouvement de basculement est permis par les moyens de guidage formés respectivement sur les parois latérales 21, 22 de ladite coque et les branches latérales de la mentonnière et est représenté schématiquement aux
Tel que représenté aux
Pour réaliser le basculement de la mentonnière de la positon fermée à la position ouverte, l'utilisateur, comme représenté aux
Sous l'effort de traction et de poussée du pouce, le curseur 52 suit ensuite une seconde portion rectiligne 512, inclinée par rapport à l'horizontale, ce qui entraîne un basculement de la mentonnière dans le sens de la flèche F4, tel que représenté en traits mixtes à la
Dans le même temps qu'elles provoquent le basculement par translation et pivotement simultanés de la mentonnière, ladite rainure 62 et ladite rotule 61 provoquent également un écartement des branches latérales 41, 42 par rapport aux parois latérales 21, 22 de la coque afin de permettre le passage de ladite mentonnière au-dessus de l'écran du casque.At the same time they cause the tilting by simultaneous translation and rotation of the chin guard, said groove 6 2 and said ball 6 1 also cause a separation of the
En effet, tel que représenté aux
Ce mouvement de translation et pivotement simultané de la mentonnière, sous l'effet de poussée opérée par l'utilisateur, se poursuit jusqu'à ce que l'écartement latéral des branches de la mentonnière soit maximal, c'est-à-dire que la rotule 61 soit située au niveau de l'extrémité B de la rainure 62 la moins profonde. Dans cette position, le mouvement de translation vers l'avant de la mentonnière dans le sens de la flèche F1 stoppe et une rotation de la mentonnière s'engage.This movement of translation and simultaneous pivoting of the chinrest, under the effect of pushing operated by the user, continues until the lateral spacing of the branches of the chinrest is maximal, that is to say that the ball 6 1 is located at the end B of the groove 6 2 shallower. In this position, the translation movement towards the front of the chinrest in the direction of arrow F1 stops and a rotation of the chin strap engages.
Avantageusement, on peut également prévoir un moyen de blocage temporaire de la mentonnière dans la position frontale afin de permettre à l'utilisateur de chausser son casque en position semi-ouverte, ce qui évite par exemple de devoir retirer des lunettes. Un tel moyen de blocage peut notamment être constitué par une encoche de blocage formée à l'extrémité de la section rectiligne 512 du rail 51 de guidage du curseur 52 sur chaque branche de la mentonnière.Advantageously, it is also possible to provide a temporary locking means of the chinrest in the frontal position to allow the user to put his helmet in the semi-open position, which avoids for example having to remove glasses. Such locking means may in particular be constituted by a locking notch formed at the end of the rectilinear section 12 of the guide rail 5 1 of the slider 5 2 on each leg of the chin.
Ensuite, toujours sous l'effort de poussée de l'utilisateur, la mentonnière effectue alors un mouvement de rotation autour des rotules 61 des parois latérales de la coque, le curseur 52 de la mentonnière glissant dans une portion circulaire 513 du rail 51 de la paroi latérale 21 correspondante de la coque, tel que représenté à la
Ceci permet à la mentonnière de basculer depuis une position frontale du casque vers l'arrière de la coque, en passant au-dessus de l'écran, sans frottement, contre la paroi externe de celui-ci.This allows the chinrest to tilt from a frontal position of the helmet to the rear of the shell, passing over the screen, without friction, against the outer wall thereof.
Une fois que le curseur 52 des branches latérales de la mentonnière a parcouru l'ensemble de la portion circulaire 513 du rail 51, ladite mentonnière 4 est positionnée à l'arrière de la coque 2 et elle suit ensuite un nouveau mouvement de translation vers l'avant du casque et de rotation simultanés autour du pivot 61, guidé par une nouvelle portion rectiligne 514 du rail 51 inclinée, le glissement du curseur dans cette nouvelle portion rectiligne provoquant un rapprochement de la mentonnière vers la paroi arrière 23 de la coque de manière à ce que ladite mentonnière vienne épouser le profil de ladite coque, dans le même temps que la branche latérale 41de la mentonnière se rapprochent de la paroi latérale 21de la coque par glissement de la rainure 52 sur la rotule 61 jusqu'à son extrémité A de profondeur maximale.Once the slider 5 2 of the lateral branches of the chin strap has traversed the whole of the circular portion 13 of the rail 5 1 , said
Pour maintenir la position ouverte de la mentonnière la plus stable possible, la portion terminale du rail 51 sur chacune des parois latérales de la coque, comporte un portion rectiligne horizontale 515, dans laquelle vient buter le curseur 52 des branches lorsque la mentonnière a atteint sa position ouverte dans laquelle elle est positionnée à l'arrière, contre la paroi, et dans la continuité du profil de la coque 2, lequel profil peut comporter, tel que représenté à la
Le retour de la mentonnière, depuis la position ouverte à la position fermée, s'effectue ensuite selon une trajectoire inverse à celle décrite précédemment, guidé par glissement du curseur 52 et de la rainure 62 formés sur chacune des branches latérales de la mentonnière, respectivement dans ledit rail 51 et sur ladite rotule 61 formés sur les parois latérales de la coque.The return of the chin guard, from the open position to the closed position, is then carried out in a reverse trajectory to that described above, guided by sliding of the slider 5 2 and the groove 6 2 formed on each of the lateral branches of the chin guard , respectively in said rail 5 1 and said ball 6 1 formed on the side walls of the hull.
Afin de permettre de limiter l'amplitude du mouvement de la mentonnière, l'axe de rotation propre de l'écran 3, qui est non représenté, est avantageusement positionné en retrait par rapport à ladite rotule 61 sur chacune des parois latérales 21, 22 vers l'arrière de la coque. Ceci permet, lors du relevage dudit écran, que la surface interne de celui-ci se rapproche de la surface externe de la coque, permettant ainsi de diminuer le débattement nécessaire de la mentonnière par rapport à l'écran et la coque et, donc, de diminuer la longueur de la rainure 62 formée sur chacune des branches latérales de la mentonnière.In order to make it possible to limit the amplitude of the movement of the chinrest, the own axis of rotation of the
En outre, pour supprimer encore les vibrations ainsi que le ballant de la mentonnière lorsque les branches de celles-ci sont écartées par rapport aux parois latérales de la coque, la surface desdites parois est avantageusement conçue pour épouser le profil interne desdites branches de la mentonnière dans toutes les position de celle-ci par rapport à la coqueIn addition, to further remove the vibration and the dangling of the chin guard when the branches thereof are spaced from the side walls of the shell, the surface of said walls is advantageously designed to match the internal profile of said branches of the chinrest in all positions thereof relative to the hull
Dans un mode de réalisation avantageux non représenté sur les figures, ledit écran comporte également, au niveau de son axe de rotation, un moyen de relevage automatique. Ce moyen de relevage peut être déclenché automatique lors de l'ouverture manuelle de la mentonnière. En complément, le casque selon l'invention peut également être doté d'un système de verrouillage de la mentonnière en position fermée, également non représenté.In an advantageous embodiment not shown in the figures, said screen also comprises, at its axis of rotation, an automatic lifting means. This lifting means can be triggered automatically when manually opening the chinrest. In addition, the helmet according to the invention may also be provided with a locking system of the chinrest in the closed position, also not shown.
De tels systèmes de relevage de l'écran et de verrouillage d'une mentonnière mobile sont connus de l'art antérieur et ne seront pas décrits plus avant ici.Such screen lifting and locking systems of a movable chin guard are known from the prior art and will not be described further here.
On réalise ainsi, conformément à ce qui a été décrit précédemment, un casque de protection comportant une mentonnière mobile présentant, pour l'utilisation du casque dans une configuration de type "Intégral", une étanchéité parfaite entre l'écran et la mentonnière, ainsi qu'une résistance aux chocs accrue de l'écran et de la mentonnière par rapport au casque à mentonnière mobile connu jusqu'alors, ainsi qu'une esthétique et une aérodynamique satisfaisante dans la position ouverte de la mentonnière pour l'utilisation du casque dans une configuration de type "Jet".Thus, in accordance with what has been described above, a protective helmet comprising a movable chin strap having, for the use of the helmet in an "integral" type configuration, a perfect seal between the screen and the chin strap, as well as increased shock resistance of the screen and chin strap compared to the previously known movable chin strap, as well as satisfactory aesthetics and aerodynamics in the open position of the chin strap for use of the helmet in a configuration of type "Jet".
