Definitions
- the present invention relates to a protective helmet, in particular a helmet for bikers, provided with a retractable functional visor inside the helmet, in particular a sun visor, or sun visor, or for example a visor for vision in foggy weather.
- a helmet generally comprises a shell having a viewing aperture, a first visor for protecting the user from wind and weather, movably attached to said shell or any other part of said helmet, such as a protective element. maxillary detachably fixed, for example by a hinge, to the hull.
- the first visor can be moved outside the shell between a first open position in which said first visor is disposed substantially entirely above the viewing opening and a second closed position in which the first visor covers substantially entirely said opening, a second functional visor movable within the shell by means of a positioning mechanism between a first position in which the second visor is disposed substantially entirely above the viewing aperture and a second position in which it is disposed in at least a portion of the viewing aperture.
- the positioning mechanism generally comprises an activating member movable between a first position in which the second visor is in its first position and a second position in which the second visor is in its second position.
- An element for transmitting the movement of the activation element to the second visor having two ends is also provided, a first end of the latter being connected to the activation element and the second end to the second visor.
- the German patent DE 4416921 describes a retractable solar visor helmet in which this visor can be moved by sliding between a first position in which this visor is outside the field of the viewing aperture of the helmet and a second position in which said visor is in the field of the viewing aperture in question, by means of a positioning mechanism comprising an activation element comprising a slider disposed above the helmet shell and passing therethrough.
- Such a mechanism has the disadvantage of requiring the user to raise his arm to the top of the helmet to actuate the visor via the activation element, such a movement may be likely to destabilize this user when is for example on the handlebars of a motorcycle running.
- Such a helmet present therefore if not a danger, at least a discomfort for its user.
- the European patent EP 1393642 overcomes this disadvantage by proposing a retractable second solar visor helmet in which this visor pivots on two distinct axes of pivoting axes of the first visor of the helmet and has a lateral extension to which is connected an end of a rigid lever whose other end is connected to an activation element disposed laterally relative to the shell of the helmet, so as to prevent the user from having to actuate the solar visor from the top of this hull.
- a helmet also has certain disadvantages. In particular, it makes it difficult to replace the solar visor in the event of breaking or scratching of the latter, since this operation requires the visor not only to be removed from its pivot axes but also from the lever which controls it.
- pivot axes are not very accessible because they are located under the textile and foam lining which covers the inside of the shell of the helmet, the removal of this lining may compromise its repositioning and even in case of repositioning possibility, if it is not adequate, it can itself compromise the effectiveness of the damping lining in question, shocks received by the helmet in case of fall of its user.
- a pivoting solar visor being rotated and not slidably moved between its first position above the viewing aperture and its second position in the field of the viewing aperture, the visor arrangement relative to the opening of vision in this second position is conditioned by the radius of said rotation and therefore by the arrangement of the pivot axes of the visor in the helmet and therefore, by the shape of its shell.
- a good position of the visor in the field of vision opening will therefore lead to manufacturing constraints on the shape of the helmet shell and the position of the pivoting axes of the visor in this shell.
- a pivoting visor also constrains during the manufacture of the helmet, a perfectly precise positioning of its pivot axes in the shell, otherwise the position of the visor will be asymmetrical in the viewing aperture, which may be functionally and aesthetically unpleasant for the user.
- a sun visor positioning mechanism comprises an activating element disposed in the vicinity of the lower edge of the shell, comprising a slider that is movable between a first position in which the sun visor is above the viewing aperture and a second position in which this visor is the field of this opening.
- An element for transmitting the movement of the activation element to the solar visor is disposed inside the shell and consists of two cables whose respective first ends are connected to the activation element and each second end is connected to one end of the lower edge of the visor, respectively at one of the lateral sides thereof.
- the positioning mechanism of the solar visor pushes it upwards to bring it to its position above the viewing aperture and pulls it downwards to bring it into its position in the field of view. this opening.
- This mechanism has the drawbacks of requiring two cables to move the solar visor between the two aforementioned positions, which complicates the manufacture of the helmet.
- the movement printed by each of the cables at one end of the lower edge of said visor must be perfectly synchronized and of the same amplitude, otherwise the sides of the visor could get stuck in the grooves in which they are arranged to slide. Such synchronization prohibits the slightest movement of the cables in the helmet, which further complicates the manufacture.
- the displacement of the activation element of the transmission mechanism being directly transmitted to the visor via the cables of question, the amplitude of this displacement must necessarily correspond to that of the displacement of the sides of the visor in the grooves in which they slide, which can make the amplitude of displacement of the activation element in question important, to the detriment of the ease of its handling by the user of the helmet.

- the invention solves the aforementioned problems of retractable functional visor helmets according to the state of the art, in that such a connection allows a displacement of the second visor using a single transmission element without risk of jamming or arcboutement of the second visor in the sliding means.

Description
"Casque de protection à visière solaire rétractable" "Safety helmet with retractable solar visor"
La présente invention se rapporte à un casque de protection, notamment un casque pour motards, muni d'une visière fonctionnelle rétractable à l'intérieur du casque, en particulier une visière de protection solaire, ou visière solaire, ou par exemple une visière de vision par temps de brouillard. Un tel casque comprend généralement une coque comportant une ouverture de vision, une première visière destinée à protéger l'utilisateur du vent et des intempéries, fixée de manière mobile à ladite coque ou à toute autre partie dudit casque, comme par exemple un élément de protection maxillaire fixé de manière détachable, par exemple par une articulation, à la coque. La première visière peut être déplacée à l'extérieur de la coque entre une première position d'ouverture dans laquelle ladite première visière est disposée sensiblement entièrement au dessus de l'ouverture de vision et une seconde position de fermeture dans laquelle la première visière recouvre sensiblement entièrement ladite ouverture, une seconde visière fonctionnelle pouvant être déplacée à l'intérieur de la coque au moyen d'un mécanisme de positionnement entre une première position dans laquelle la seconde visière est disposée sensiblement entièrement au dessus de l'ouverture de vision et une seconde position dans laquelle elle est disposée dans au moins une partie de l'ouverture de vision. Le mécanisme de positionnement comprend généralement un élément d'activation pouvant être déplacé entre une première position dans laquelle la seconde visière se trouve dans sa première position et une
seconde position dans laquelle la seconde visière se trouve dans sa seconde position. Un élément de transmission du mouvement de l'élément d'activation à la seconde visière possédant deux extrémités est également prévu, une première extrémité de ce dernier étant connectée à l'élément d'activation et la seconde extrémité à la seconde visière.The present invention relates to a protective helmet, in particular a helmet for bikers, provided with a retractable functional visor inside the helmet, in particular a sun visor, or sun visor, or for example a visor for vision in foggy weather. Such a helmet generally comprises a shell having a viewing aperture, a first visor for protecting the user from wind and weather, movably attached to said shell or any other part of said helmet, such as a protective element. maxillary detachably fixed, for example by a hinge, to the hull. The first visor can be moved outside the shell between a first open position in which said first visor is disposed substantially entirely above the viewing opening and a second closed position in which the first visor covers substantially entirely said opening, a second functional visor movable within the shell by means of a positioning mechanism between a first position in which the second visor is disposed substantially entirely above the viewing aperture and a second position in which it is disposed in at least a portion of the viewing aperture. The positioning mechanism generally comprises an activating member movable between a first position in which the second visor is in its first position and a second position in which the second visor is in its second position. An element for transmitting the movement of the activation element to the second visor having two ends is also provided, a first end of the latter being connected to the activation element and the second end to the second visor.
Des exemples de tels casques à visière fonctionnelle rétractable, en particulier visière solaire, sont illustrés par les documents de l'état de la technique suivants, ces casques présentant cependant plusieurs inconvénients: Le brevet allemand DE 4416921 décrit un casque à visière solaire rétractable dans lequel cette visière peut être déplacée par coulissement entre une première position dans laquelle cette visière se trouve hors du champ de l'ouverture de vision du casque et une seconde position dans laquelle ladite visière se trouve dans le champ de l'ouverture de vision en question, au moyen d'un mécanisme de positionnement comprenant un élément d'activation comprenant un curseur disposé au dessus de la coque du casque et traversant cette dernière. Un tel mécanisme présente l'inconvénient d'obliger l'utilisateur à relever son bras jusqu'au dessus du casque pour en actionner la visière via l'élément d'activation, un tel mouvement pouvant être de nature à déstabiliser cet utilisateur lorsqu'il est par exemple au guidon d'une moto en marche. Un tel casque présente dès lors sinon un danger, à tout le moins un inconfort pour son utilisateur.Examples of such retractable functional visor helmets, in particular sun visor, are illustrated by the following documents of the prior art, these helmets having however several disadvantages: The German patent DE 4416921 describes a retractable solar visor helmet in which this visor can be moved by sliding between a first position in which this visor is outside the field of the viewing aperture of the helmet and a second position in which said visor is in the field of the viewing aperture in question, by means of a positioning mechanism comprising an activation element comprising a slider disposed above the helmet shell and passing therethrough. Such a mechanism has the disadvantage of requiring the user to raise his arm to the top of the helmet to actuate the visor via the activation element, such a movement may be likely to destabilize this user when is for example on the handlebars of a motorcycle running. Such a helmet present therefore if not a danger, at least a discomfort for its user.
Le brevet européen EP 1393642 pallie cet inconvénient en proposant un casque à seconde visière solaire rétractable dans lequel cette visière pivote sur deux axes distincts d'axes de pivotement de la première visière du casque et présente une extension latérale à laquelle est connectée une extrémité d'un levier rigide dont l'autre extrémité est connectée à un élément d'activation disposé latéralement relativement à la coque du casque, de sorte à éviter à l'utilisateur de devoir actionner la
visière solaire depuis le dessus de cette coque. Un tel casque présente cependant également certains inconvénients. En particulier, il rend difficile le remplacement de la visière solaire en cas de brisure ou de griffures de cette dernière, dès lors que cette opération demande de démonter la visière non seulement de ses axes de pivotement mais aussi du levier qui la commande. Or, lesdits axes de pivotement sont peu accessibles car ils sont situés sous la garniture de textile et de mousse qui recouvre l'intérieur de la coque du casque, le retrait de cette garniture pouvant compromettre son repositionnement et même en cas de possibilité de repositionnement, si celui-ci s'il n'est pas adéquat, il peut lui-même compromettre l'efficacité de l'amortissement par garniture en question, de chocs reçus par le casque en cas de chute de son utilisateur. En outre, une visière solaire pivotante étant déplacée par rotation et non par coulissement entre sa première position au dessus de l'ouverture de vision et sa seconde position dans le champ de l'ouverture de vision, la disposition de la visière relativement à l'ouverture de vision dans cette seconde position est conditionnée par le rayon de ladite rotation et donc par la disposition des axes de pivotement de la visière dans le casque et dès lors, par la forme de sa coque. Une bonne position de la visière dans le champ de l'ouverture de vision, de nature en particulier à ne pas gêner le visage de l'utilisateur, entrainera dès lors des contraintes de fabrication sur la forme de la coque du casque et la position des axes de pivotement de la visière dans cette coque. Par ailleurs, une telle visière pivotante contraint également lors de la fabrication du casque, à un positionnement parfaitement précis de ses axes de pivotement dans la coque, faute de quoi la position de la visière sera asymétrique dans l'ouverture de vision, ce qui pourra être fonctionnellement et esthétiquement désagréable pour l'utilisateur.The European patent EP 1393642 overcomes this disadvantage by proposing a retractable second solar visor helmet in which this visor pivots on two distinct axes of pivoting axes of the first visor of the helmet and has a lateral extension to which is connected an end of a rigid lever whose other end is connected to an activation element disposed laterally relative to the shell of the helmet, so as to prevent the user from having to actuate the solar visor from the top of this hull. Such a helmet, however, also has certain disadvantages. In particular, it makes it difficult to replace the solar visor in the event of breaking or scratching of the latter, since this operation requires the visor not only to be removed from its pivot axes but also from the lever which controls it. However, said pivot axes are not very accessible because they are located under the textile and foam lining which covers the inside of the shell of the helmet, the removal of this lining may compromise its repositioning and even in case of repositioning possibility, if it is not adequate, it can itself compromise the effectiveness of the damping lining in question, shocks received by the helmet in case of fall of its user. In addition, a pivoting solar visor being rotated and not slidably moved between its first position above the viewing aperture and its second position in the field of the viewing aperture, the visor arrangement relative to the opening of vision in this second position is conditioned by the radius of said rotation and therefore by the arrangement of the pivot axes of the visor in the helmet and therefore, by the shape of its shell. A good position of the visor in the field of vision opening, particularly in nature not to interfere with the face of the user, will therefore lead to manufacturing constraints on the shape of the helmet shell and the position of the pivoting axes of the visor in this shell. Moreover, such a pivoting visor also constrains during the manufacture of the helmet, a perfectly precise positioning of its pivot axes in the shell, otherwise the position of the visor will be asymmetrical in the viewing aperture, which may be functionally and aesthetically unpleasant for the user.
Les inconvénients d'une visière solaire pivotante sont palliés par la demande de brevet WO 2006/037294, qui décrit un casque
dont la visière fonctionnelle, solaire, coulisse dans un cadre constitué de deux gorges latérales dans lesquelles glissent les deux côtés latéraux de la visière transversaux à ses deux bords supérieur et inférieur. Un mécanisme de positionnement de Ia visière solaire comprend un élément d'activation disposé au voisinage du bord inférieur de la coque, comprenant un curseur qui peut être déplacé entre une première position dans laquelle la visière solaire se trouve au dessus de l'ouverture de vision et une seconde position dans laquelle cette visière se trouve le champ de cette ouverture. Un élément de transmission du mouvement de l'élément d'activation à la visière solaire est disposé à l'intérieur de la coque et est constitué de deux câbles dont les premières extrémités respectives sont connectées à l'élément d'activation et chaque deuxième extrémité est connectée à une extrémité du bord inférieur de la visière, respectivement au niveau d'un des côtés latéraux de celle-ci. En fonctionnement, le mécanisme de positionnement de la visière solaire pousse celle-ci vers le haut pour l'amener à sa position au dessus de l'ouverture de vision et la tire vers le bas pour l'amener dans sa position dans le champ de cette ouverture. Ce mécanisme présente les inconvénients de nécessiter deux câbles pour déplacer la visière solaire entre les deux positions susmentionnées, ce qui complique la fabrication du casque. En outre, le mouvement imprimé par chacun des câbles à une extrémité du bord inférieur de ladite visière doit être parfaitement synchronisé et de même amplitude, faute de quoi les côtés la visière pourrait se coincer dans les gorges dans lesquelles ils sont agencés pour coulisser. Une telle synchronisation interdit le moindre mouvement des câbles dans le casque, ce qui en complique encore la fabrication. De plus, le déplacement de l'élément d'activation du mécanisme de transmission étant directement transmis à la visière via les câbles dont question, l'amplitude de ce déplacement doit obligatoirement correspondre à celle du déplacement des côtés de la visière dans les
gorges dans lesquelles ils coulissent, ce qui peut rendre l'amplitude du déplacement de l'élément d'activation en question importante, au détriment de l'aisance de sa manipulation par l'utilisateur du casque.The drawbacks of a pivoting solar visor are overcome by the patent application WO 2006/037294, which describes a helmet whose functional visor, solar, slides in a frame consisting of two lateral grooves in which slide the two lateral sides of the transverse visor at its two upper and lower edges. A sun visor positioning mechanism comprises an activating element disposed in the vicinity of the lower edge of the shell, comprising a slider that is movable between a first position in which the sun visor is above the viewing aperture and a second position in which this visor is the field of this opening. An element for transmitting the movement of the activation element to the solar visor is disposed inside the shell and consists of two cables whose respective first ends are connected to the activation element and each second end is connected to one end of the lower edge of the visor, respectively at one of the lateral sides thereof. In operation, the positioning mechanism of the solar visor pushes it upwards to bring it to its position above the viewing aperture and pulls it downwards to bring it into its position in the field of view. this opening. This mechanism has the drawbacks of requiring two cables to move the solar visor between the two aforementioned positions, which complicates the manufacture of the helmet. In addition, the movement printed by each of the cables at one end of the lower edge of said visor must be perfectly synchronized and of the same amplitude, otherwise the sides of the visor could get stuck in the grooves in which they are arranged to slide. Such synchronization prohibits the slightest movement of the cables in the helmet, which further complicates the manufacture. In addition, the displacement of the activation element of the transmission mechanism being directly transmitted to the visor via the cables of question, the amplitude of this displacement must necessarily correspond to that of the displacement of the sides of the visor in the grooves in which they slide, which can make the amplitude of displacement of the activation element in question important, to the detriment of the ease of its handling by the user of the helmet.
La présente invention pallie les inconvénients susmentionnés en offrant un casque de protection comprenant une coque comportant une ouverture de vision, une garniture intérieure, une première visière fixée de manière mobile à ladite coque ou à une autre partie du casque et pouvant être déplacée à l'extérieur de cette dernière entre une première position d'ouverture dans laquelle la première visière est disposée sensiblement entièrement au dessus de l'ouverture de vision et une seconde position de fermeture dans laquelle la première visière recouvre sensiblement entièrement ladite ouverture, une seconde visière fonctionnelle comprenant un bord inférieur et un bord supérieur disposé au dessus du bord inférieur relativement au bord inférieur de la coque, un moyen de coulissement de la seconde visière à l'intérieur de la coque, un mécanisme de positionnement de la seconde visière par coulissement de cette dernière dans le moyen de coulissement entre une première position dans laquelle la seconde visière se trouve sensiblement entièrement au dessus de l'ouverture de vision et une seconde position dans laquelle elle se trouve dans au moins la partie supérieure de l'ouverture de vision, le mécanisme de positionnement comprenant un élément d'activation disposé au voisinage du bord inférieur de la coque et pouvant être déplacé entre une première position dans laquelle la seconde visière se trouve dans sa première position et une seconde position dans laquelle la seconde visière se trouve dans sa seconde position, le mécanisme de positionnement comprenant encore un élément de transmission du mouvement de l'élément d'activation à Ia seconde visière, disposé à l'intérieur de la coque et possédant deux extrémités, une première extrémité étant connectée à l'élément
d'activation. La deuxième extrémité de l'élément de transmission est connectée à la seconde visière au niveau de son bord supérieur, soit directement, au voisinage du centre de ce bord, soit par l'intermédiaire d'un moyen d'entraînement de la seconde visière compris dans le mécanisme de positionnement, connecté à la seconde visière au voisinage du centre dudit bord supérieur ou sensiblement symétriquement relativement à ce dernier.The present invention overcomes the aforementioned disadvantages by providing a protective helmet comprising a shell having a viewing aperture, an interior liner, a first visor movably attached to said shell or other portion of the helmet and movable to the exterior of the latter between a first open position in which the first visor is disposed substantially entirely above the viewing aperture and a second closed position in which the first visor substantially completely covers said opening, a second functional visor comprising a lower edge and an upper edge disposed above the lower edge relative to the lower edge of the shell, a sliding means of the second visor inside the shell, a mechanism for positioning the second visor by sliding the latter in the sliding means between a first position in which the second visor is substantially entirely above the viewing aperture and a second position in which it is in at least the upper portion of the viewing aperture, the positioning mechanism comprising an aperture element; activation disposed in the vicinity of the lower edge of the shell and movable between a first position in which the second visor is in its first position and a second position in which the second visor is in its second position, the positioning mechanism comprising still an element for transmitting the movement of the activation element to the second visor, disposed inside the shell and having two ends, a first end being connected to the element activation.

A sliding means 6 of the second visor inside the shell is constituted in the illustrated embodiment of a frame arranged inside the shell above the viewing aperture between said shell and the trim interior, comprising an upper portion 6a and a lower portion 6b superimposed, substantially matching the shape of the second visor and between which it can slide, so that in its first position, the second visor is disposed substantially in its entirety between the lower and upper parts of the frame. Alternatively, the sliding means may consist for example of two troughs arranged in the helmet between its shell and its inner lining on either side of the second visor in its first position and in which the lateral edges of the second visor, substantially orthogonal to its upper and lower edges, can slide. A mechanism for positioning the second visor by sliding the latter in the sliding means between its first position and a second position is also provided. FIGS. 3a and 3b illustrate the second visor respectively in its first position A and its second position B. The positioning mechanism, illustrated in FIG. 2, comprises the activation element 7 as well as an element 8 for transmitting motion from the activation element to the second visor, comprising in the illustrated embodiment, a single cable 8a and a sheath 8b in which said cable is slidable and disposed within the shell. Alternatively, the transmission element 8 may comprise instead of the cable 8a a rigid arm conforming to the shape of the inside of the shell of the helmet. The 8a of the transmission element 8 has two ends, the first of which is connected to the activation element and the second to the second visor at its upper edge, via a drive means 9 of this second visor , included in the positioning mechanism and connected to the second visor substantially symmetrically relative to the center of the upper edge thereof.
Selon le mode de réalisation illustré, le moyen d'entrainement comprend deux leviers 9a pouvant chacun pivoter autour d'un axe 9b différent compris dans le moyen d'entrainement et fixé à la face externe relativement à la deuxième visière de la partie supérieure 6a du cadre 6. Chaque levier est de dimensions sensiblement identiques et leurs axes respectifs sont disposés symétriquement relativement à une médiane de la partie supérieure du cadre, sensiblement orthogonale aux bords supérieur et inférieur de cette partie supérieure. Chaque levier est connecté par son premier côté relativement à son axe au bord supérieur de la seconde visière et par son second côté à l'extrémité de l'élément de transmission par l'intermédiaire d'un élément de couplage 9c également compris dans le moyen d'entraînement. La connexion du premier côté de chaque levier au bord de la visière est sensiblement symétrique relativement au centre de ce bord et réalisée via un élément de connexion 9d, constitué d'un clips, compris dans le moyen d'entrainement, disposés sensiblement symétriquement relativement au bord supérieur de la première visière et dans lesquels peut s'engager par clipsage ledit bord, les parties de celui-ci s'engageant dans de tels clips étant agencées pour coopérer avec ces clips.According to the illustrated embodiment, the drive means comprises two levers 9a each pivotable about a different axis 9b included in the drive means and fixed to the outer face relative to the second visor of the upper portion 6a of the 6. Each lever is of substantially identical dimensions and their respective axes are arranged symmetrically relative to a median of the upper part of the frame, substantially orthogonal to the upper and lower edges of this upper part. Each lever is connected by its first side relative to its axis to the upper edge of the second visor and by its second side to the end of the transmission element via a coupling element 9c also included in the means. drive. The connection of the first side of each lever to the edge of the visor is substantially symmetrical relative to the center of this edge and made via a connecting member 9d, consisting of a clip, included in the drive means, arranged substantially symmetrically relative to the upper edge of the first visor and in which can engage by clipping said edge, the parts thereof engaging in such clips being arranged to cooperate with these clips.
Alternativement, le moyen d'entrainement de la seconde visière peut être connecté à son bord supérieur par pinçage, par collage ou par tout autre moyen connu de l'homme du métier. Le clipsage de la seconde visière dans le moyen d'entrainement offre l'avantage de
permettre le remplacement aisé de cette seconde visière en cas de brisure ou de rayures de cette dernière.Alternatively, the drive means of the second visor can be connected to its upper edge by clamping, gluing or by any other means known to those skilled in the art. The clipping of the second visor into the driving means offers the advantage of allow easy replacement of the second visor in case of breakage or scratches thereof.
Chaque clips 9d est agencé pour coulisser d'une part dans une gorge 6c distincte, ménagée dans la partie supérieure 6a du cadre 6, sensiblement parallèlement et symétriquement à la médiane susmentionnée et dans une gorge 9e ménagée dans le premier côté de chaque levier 9a correspondant. L'élément de couplage 9c est agencé pour coulisser d'une part dans une gorge 6d ménagée dans la partie supérieure 6a du cadre 6, sensiblement au niveau de ladite médiane et d'autre part dans une gorge 9f ménagée dans le second côté de chaque levier. Il va de soi que le moyen d'entraînement peut également être agencé de manière similaire à ce qui vient d'être décrit mais relativement à la face antérieure de la partie inférieure 6b du cadre 6, dans laquelle partie sont alors prévues les gorges 6c et 6d. Alternativement, la seconde extrémité du mécanisme de positionnement peut être directement connectée à la seconde visière, au voisinage du centre du bord supérieur de cette dernière, ou alternativement encore, par l'intermédiaire d'un moyen d'entrainement, également connecté à la seconde visière au voisinage du centre de son bord supérieur. Par exemple, un tel moyen d'entrainement peut ne comprendre qu'un élément de couplage, par exemple agencé pour coulisser dans une gorge ménagée dans la partie supérieure du cadre, sensiblement selon la médiane de cette partie, la seconde extrémité de l'élément de transmission étant connectée à un côté dudit élément de couplage, son côté opposé étant connecté, par exemple par clipsage, à la seconde visière. Alternativement, un tel moyen d'entrainement connecté à la seconde visière au voisinage du centre de son bord supérieur peut comprendre un seul levier 9a, son axe 9b étant alors par exemple agencé pour que son premier côté soit connecté au bord supérieur de la visière au voisinage du centre de ce bord via un clips 9d
coulissant alors dans une gorge 6c unique ménagée dans la partie supérieure 6a du cadre 6, ensiblement selon la médiane de cette partie supérieure et le second côté du levier étant alors connecté à la seconde extrémité de l'élément de transmission 8 par un élément de couplage 9c pouvant coulisser dans une gorge 9f dudit second côté et dans une gorge 6d ménagée dans la partie supérieure 6a du moyen de coulissement, sensiblement parallèlement à la médiane de cette partie supérieure.Each clip 9d is arranged to slide on the one hand in a separate groove 6c formed in the upper part 6a of the frame 6, substantially parallel and symmetrically to the aforementioned median and in a groove 9e formed in the first side of each lever 9a corresponding . The coupling element 9c is arranged to slide on the one hand in a groove 6d formed in the upper part 6a of the frame 6, substantially at the level of said median and on the other hand in a groove 9f formed in the second side of each the sink. It goes without saying that the drive means may also be arranged similarly to what has just been described but relative to the front face of the lower part 6b of the frame 6, in which part the grooves 6c and 6c are then provided. 6d. Alternatively, the second end of the positioning mechanism can be directly connected to the second visor, near the center of the upper edge thereof, or alternatively still, via a drive means, also connected to the second visor near the center of its upper edge. For example, such a drive means may comprise only a coupling element, for example arranged to slide in a groove formed in the upper part of the frame, substantially along the median of this part, the second end of the element transmission member being connected to a side of said coupling member, its opposite side being connected, for example by clipping, to the second visor. Alternatively, such a drive means connected to the second visor near the center of its upper edge may comprise a single lever 9a, its axis 9b then being for example arranged so that its first side is connected to the upper edge of the visor at neighborhood of the center of this edge via a 9d clips then sliding in a single groove 6c formed in the upper part 6a of the frame 6, moreover according to the median of this upper part and the second side of the lever then being connected to the second end of the transmission element 8 by a coupling element 9c being slidable in a groove 9f of said second side and in a groove 6d formed in the upper part 6a of the sliding means, substantially parallel to the median of this upper part.
Le mécanisme de positionnement de la seconde visière selon l'invention tel qu'illustré par les figures jointes fonctionne de la manière suivante: L'utilisateur déplace par translation le curseur 7a de l'élément d'activation 7 de sa première position C vers sa seconde position D. Ce déplacement entraîne par traction la première extrémité du câble 8a qui coulisse dans sa gaine 8b. La seconde extrémité du câble 8a entraîne alors l'élément de couplage 9c qui coulisse dans la gorge 6d de la partie supérieur 6a du cadre du moyen de coulissement 6. L'élément de couplage 9c coulisse également dans chaque gorge 9f du second côté de chaque levier 9a qui dès lors pivote sur son axe 9b et dont le premier côté entraine alors par coulissement dans sa gorge 9e le clips 9d correspondant qui coulisse de ce fait également dans une gorge 6c de la partie supérieure 6a du cadre 6 et entraine par conséquent par poussée la seconde visière dont le bord supérieur est clipsé dans chaque clips 9d, dans un déplacement entre sa première position A à sa seconde position B, tel qu'illustré par les figures 3a et 3b. Inversement, en déplaçant le curseur 7a de sa position seconde D à sa première position C, une poussée est exercée sur le câble 8a, qui par l'intermédiaire du moyen d'entraînement 9, est convertie en traction sur la seconde visière 5, laquelle se déplace alors de sa seconde position B vers sa première position A.The positioning mechanism of the second visor according to the invention as illustrated by the attached figures operates in the following manner: The user translates the slider 7a of the activation element 7 from its first position C to its second position D. This displacement pulls the first end of the cable 8a which slides in its sheath 8b. The second end of the cable 8a then drives the coupling element 9c which slides in the groove 6d of the upper part 6a of the frame of the sliding means 6. The coupling element 9c also slides in each groove 9f of the second side of each lever 9a which then pivots on its axis 9b and whose first side then drives by sliding in its groove 9e the corresponding clip 9d which also slides in a groove 6c of the upper part 6a of the frame 6 and therefore leads to pushed the second visor whose upper edge is clipped into each clip 9d, in a displacement between its first position A to its second position B, as shown in Figures 3a and 3b. Conversely, by moving the slider 7a from its second position D to its first position C, a thrust is exerted on the cable 8a, which, via the driving means 9, is converted into traction on the second visor 5, which then moves from its second position B to its first position A.
Dans le mode de réalisation illustré, l'axe de chaque levier est agencé relativement à ses extrémités pour que le déplacement de
l'élément d'activation soit amplifié par ledit levier en un déplacement de plus grande amplitude de la seconde visière.
In the illustrated embodiment, the axis of each lever is arranged relative to its ends so that the displacement of the activation element is amplified by said lever in a displacement of greater amplitude of the second visor.
