Description

L'invention concerne le domaine des casques destinés aux pilotes d'avions.The invention relates to the field of helmets intended for aircraft pilots.

L'invention se rapporte notamment aux casques munis d'équipements de visualisation, tels que des dispositifs de vision nocturne.The invention particularly relates to helmets equipped with visualization equipment, such as night vision devices.

Ces casques doivent répondre à plusieurs contraintes liées à leur utilisation spécifique.These helmets must meet several constraints related to their specific use.

En particulier, ces casques doivent présenter un volume réduit et une masse minimale et équilibrée, présentant un centre de gravité dont la position est optimisée, afin de limiter les risques de blessure du pilote lors d'une éjection d'urgence et limiter la fatigue du pilote lors de missions de longue durée.In particular, these helmets must have a reduced volume and a minimum and balanced mass, having a center of gravity whose position is optimized, in order to limit the risk of injury to the driver during an emergency ejection and limit the fatigue of the driver. pilot during long-term missions.

Par ailleurs, ces casques comprennent une visière qui doit protéger le pilote, en vol ou lors d'une éjection.In addition, these helmets include a visor which must protect the pilot, in flight or during an ejection.

La visière doit nécessairement être en position baissée, devant le visage du pilote, pendant les phases de décollage et d'atterrissage.The visor must necessarily be in the lowered position, in front of the pilot's face, during the take-off and landing phases.

Lors d'une éjection, la visière doit être rabattue de manière automatique pour protéger le visage du pilote.During an ejection, the visor must be folded automatically to protect the face of the driver.

La visière doit pouvoir être verrouillée en position baissée pour que le casque présente une bonne tenue au windblast (choc aérodynamique au moment de l'éjection).The visor must be locked in the down position for the helmet has a good resistance to windblast (aerodynamic shock at the time of ejection).

Par ailleurs, ces casques doivent pouvoir être utilisées pour des missions de longue durée, qui peuvent avoir lieu à la fois le jour et la nuit. Les casques doivent donc pouvoir être munis d'un dispositif de vision nocturne, d'une visière claire et d'une visière tentée.In addition, these helmets must be able to be used for long-term missions, which can take place both day and night. The helmets must therefore be equipped with a night vision device, a clear visor and an attempted visor.

Enfin, ces casques sont généralement personnalisés en fonction de la morphologie de la tête du pilote. En particulier, les équipements de visualisation doivent généralement être réglés et positionnés avec précision en fonction des yeux du pilote.Finally, these helmets are usually customized according to the morphology of the driver's head. In particular, the display equipment must generally be adjusted and positioned precisely according to the eyes of the pilot.

Le document US 5 416 315 décrit un casque comprenant une coque et une visière munie d'un dispositif de vision nocturne compact. La visière est montée rotative sur la coque entre une position baissée, dans laquelle le dispositif de vision nocturne s'étend devant les yeux du pilote, et une position relevée, dans laquelle le dispositif de vision nocturne s'étend au-dessus du visage du pilote.The document US 5,416,315 describes a helmet comprising a shell and a visor provided with a compact night vision device. The visor is rotatably mounted on the hull between a lowered position, in which the night vision device extends in front of the pilot's eyes, and a raised position, in which the night vision device extends over the pilot's face.

Lorsque la visière équipée du dispositif de vision nocturne se trouve en position relevée, le casque présente un encombrement important.When the visor equipped with the night vision device is in the raised position, the helmet has a large footprint.

Cependant, l'espace disponible sous la verrière du cockpit n'est généralement pas suffisant pour permettre au pilote de relever la visière équipée du dispositif de vision nocturne ou permettre une mobilité de la tête du pilote. En outre, étant donné l'encombrement de la visière en position relevée, le rabattement automatique de la visière en cas d'éjection non préparée, risque d'être gêné.However, the space available under the cockpit canopy is generally not sufficient to allow the pilot to raise the visor equipped with the night vision device or allow mobility of the pilot's head. In addition, given the size of the visor in the raised position, the automatic folding of the visor in case of unprepared ejection, may be hindered.

Le document US 5 901 369 décrit un dispositif de fixation d'une visière sur une coque de casque, le dispositif étant apte a permettre un mouvement de la visière par rapport a a coque entre une position baissée et une position relevée comprenant un élément de liaison entre la visière et la coque, l'élément de liaison étant apte à être monté à rotation par rapport à la coque autour d'un premier axe de rotation et étant apte à être monté à rotation par rapport a la visière autour d'un deuxième axe de rotation.The document US 5,901,369 discloses a device for fixing a visor on a helmet shell, the device being able to allow a movement of the visor with respect to the shell between a lowered position and a raised position comprising a connecting element between the visor and the shell, the connecting element being adapted to be rotatably mounted relative to the shell about a first axis of rotation and being adapted to be rotatably mounted relative to the visor about a second axis of rotation.

Un but de l'invention est de permettre au pilote de positionner la visière du casque en position relevée (y compris une visière munie d'un équipement de visualisation).An object of the invention is to allow the pilot to position the visor of the helmet in the raised position (including a visor provided with a display equipment).

Ce problème est résolu dans le cadre de la présente invention grâce à un dispositif de fixation d'une visière sur une coque de casque, le dispositif étant apte à permettre un mouvement de la visière par rapport à la coque entre une position baissée et une position relevée, comprenant un élément de liaison entre la visière et la coque, l'élément de liaison étant apte à être monté à rotation par rapport à la coque autour d'un premier axe de rotation, et des moyens pour guider le mouvement de la visière entre la position baissée et la position relevée, caractérisé en ce que l'élément de liaison est en outre apte à être monté à rotation par rapport à la visière autour d'un deuxième axe de rotation.This problem is solved in the context of the present invention by means of a device for attaching a visor to a helmet shell, the device being able to allow movement of the visor with respect to the shell between a lowered position and a position raised, comprising a connecting element between the visor and the shell, the connecting element being adapted to be rotatably mounted relative to the shell around a first axis of rotation, and means for guiding the movement of the visor between the lowered position and the raised position, characterized in that the connecting element is further adapted to be rotatably mounted relative to the visor about a second axis of rotation.

Du fait que l'élément de liaison est monté à rotation autour d'un deuxième axe de rotation, le mouvement de la visière peut être guidé pour obtenir une position relevée présentant un encombrement réduit.Because the connecting member is rotatably mounted about a second axis of rotation, the movement of the visor can be guided to obtain a raised position having a small footprint.

En effet, grâce au deuxième axe de rotation, le mouvement de la visière peut être guidé pour que la visière bascule vers l'arrière lorsqu'elle est relevée. Cela permet de dégager le visage du pilote tout en maintenant la visière à proximité de la coque du casque.Indeed, thanks to the second axis of rotation, the movement of the visor can be guided so that the visor tilts backwards when it is raised. This clears the pilot's face while keeping the visor close to the helmet shell.

Du fait que, en position relevée, la visière est maintenue à proximité de la coque du casque, le centre de gravité du casque est peu déporté.Because, in the raised position, the visor is kept close to the helmet shell, the center of gravity of the helmet is little remote.

La coque 100 est par exemple une coque de casque aéronautique, de type LA 100 fournie par la société MSA GALLET.The hull 100 is for example an aeronautical helmet shell, type LA 100 supplied by the company MSA GALLET.

Sur la figure 1, le casque est représenté en vue de profil et une partie seulement du dispositif de fixation 300 de la visière 200 est visible Cependant, on comprendra que le dispositif de fixation 300 de la visière 200 est symétrique par rapport au plan de la figure (qui correspond plan sagittal de la tête du pilote).On the figure 1 , the helmet is shown in profile view and only part of the fixing device 300 of the visor 200 is visible However, it will be understood that the fixing device 300 of the visor 200 is symmetrical with respect to the plane of the figure (which corresponds to the sagittal plane of the pilot's head).

Le dispositif de fixation 300 de la visière 200 sur la coque 100 est apte à permettre un mouvement de la visière 200 par rapport à la coque 100 entre une position baissée (représentée en traits pointillées) et une position relevée ou position d'attente (représentée en traits pleins).The fixing device 300 of the visor 200 on the shell 100 is able to allow a movement of the visor 200 relative to the shell 100 between a lowered position (shown in dashed lines) and a raised position or waiting position (shown in FIG. in solid lines).

Le dispositif de fixation 300 comprend un support 310 apte à être fixé sur la coque 100, un bandeau 320 apte à recevoir la visière 200 et un élément de liaison 330 entre le support 310 et le bandeau 320.The fixing device 300 comprises a support 310 adapted to be fixed on the shell 100, a strip 320 adapted to receive the visor 200 and a connecting element 330 between the support 310 and the strip 320.

Le bandeau 320 est muni de moyens de fixation 321 destinés à recevoir de manière amovible des moyens de fixation 221 complémentaire de la visière 200 pour fixer la visière 200 sur le bandeau 320.The band 320 is provided with fixing means 321 for detachably receiving fixing means 221 complementary to the visor 200 to fix the visor 200 on the band 320.

Le dispositif de fixation 300 comprend en outre un coulisseau 340 apte à guider le mouvement de la visière 200 par rapport à la coque 100.The fixing device 300 further comprises a slide 340 capable of guiding the movement of the visor 200 with respect to the shell 100.

Le support 310 est apte à être fixé de manière amovible sur la coque 100 du casque. Les moyens de fixation du support 310 sur la coque 100 seront décrits plus en détail en référence à la figure 5.The support 310 is adapted to be removably attached to the shell 100 of the helmet. The fixing means of the support 310 on the shell 100 will be described in more detail with reference to the figure 5 .

L'élément de liaison 330 comprend une bielle 331 s'étendant entre le support 310 et le bandeau 320. La bielle est montée à rotation par rapport au support 310 autour d'un premier axe de rotation 332 situé au niveau d'une première extrémité de la bielle. D'autre part, la bielle 331 est montée à rotation par rapport au bandeau 320 autour d'un deuxième axe de rotation 333 situé au niveau d'une deuxième extrémité de la bielle 331 et parallèle au premier axe de rotation 332. Les premier et deuxième axes de rotation 332 et 333 s'étendent dans une direction générale perpendiculaire au plan de symétrie du casque.The connecting element 330 comprises a rod 331 extending between the support 310 and the strip 320. The rod is rotatably mounted relative to the support 310 about a first axis of rotation 332 located at a first end. of the connecting rod. On the other hand, the rod 331 is rotatably mounted relative to the strip 320 around a second axis of rotation 333 located at a second end of the rod 331 and parallel to the first axis of rotation 332. The first and second axes of rotation 332 and 333 extend in a general direction perpendicular to the plane of symmetry of the helmet.

Le coulisseau 340 est monté coulissant dans une rainure 140 ménagée dans la coque 100. Sur les casques de type LA 100, une rainure est déjà prévue sur la coque pour le guidage d'une visière claire. La rainure 140 s'étend dans le plan de symétrie du casque et présente une forme générale en arc de cercle. La rainure préexistante 140 peut être utilisée pour guider le coulisseau. Ainsi le dispositif de fixation ne nécessite pas de modification de la coque du casque.The slide 340 is slidably mounted in a groove 140 formed in the shell 100. On LA 100 type helmets, a groove is already provided on the shell for guiding a clear visor. The groove 140 extends in the plane of symmetry of the helmet and has a general shape in an arc. The pre-existing groove 140 can be used to guide the slide. Thus the fixing device does not require modification of the shell of the helmet.

Par ailleurs, le coulisseau 340 est monté à rotation par rapport au bandeau 320 autour d'un troisième axe de rotation 343, parallèle aux premier et deuxième axes de rotation 331 et 332.Furthermore, the slider 340 is rotatably mounted relative to the strip 320 around a third axis of rotation 343, parallel to the first and second axes of rotation 331 and 332.

L'élément de liaison 330 est agencé de sorte que le premier axe de rotation 332 est excentré par rapport à l'axe 141 de la rainure 140. Plus précisément, le premier axe de rotation 332 est excentré vers l'avant du casque.The connecting element 330 is arranged so that the first axis of rotation 332 is eccentric with respect to the axis 141 of the groove 140. More specifically, the first axis of rotation 332 is eccentric towards the front of the helmet.

En position baissée (représentée en traits pointillés), la visière 200 est disposée devant les yeux du pilote de sorte que le pilote visualise l'environnement extérieur à travers le dispositif de vision nocturne 201.In the down position (shown in broken lines), the visor 200 is disposed in front of the eyes of the pilot so that the pilot visualizes the outside environment through the night vision device 201.

Lorsque le pilote ne souhaite plus utiliser le dispositif de vision nocturne 201, le pilote peut relever la visière 200 pour disposer la visière 200 au-dessus de son visage, en position relevée (représentée en traits pleins).When the pilot no longer wishes to use the night vision device 201, the pilot can raise the visor 200 to place the visor 200 above his face, in the raised position (shown in solid lines).

Lors du mouvement de la visière 200 entre la position baissée et la position relevée, la visière pivote autour du premier axe 332, ce qui permet un dégagement de la visière 200 par rapport au visage du pilote, vers l'avant du casque.During the movement of the visor 200 between the lowered position and the raised position, the visor pivots around the first axis 332, which allows a release of the visor 200 relative to the pilot's face, towards the front of the helmet.

D'autre part, la visière 200 pivote également autour du deuxième axe de rotation 333 et est guidée lors de son mouvement par le coulisseau qui se déplace le long de la rainure 140. Le coulisseau 340 permet un basculement de la visière 200 vers l'arrière du casque pour maintenir la visière à proximité de la coque 100.On the other hand, the visor 200 also pivots about the second axis of rotation 333 and is guided during its movement by the slide which moves along the groove 140. The slide 340 allows a tilting of the visor 200 towards the back of the helmet to maintain the visor near the hull 100.

Le dispositif de fixation 300 comprend des moyens pour verrouiller la visière 200 en position relevée, les moyens étant aptes à libérer la visière en cas d'éjection non préparée.The fixing device 300 comprises means for locking the visor 200 in the raised position, the means being able to release the visor in case of unprepared ejection.

De tels moyens comprennent par exemple un ressort taré, qui lorsque l'accélération du casque dépasse un seuil prédéterminé (typiquement à 10 G), libère la visière, ou encore un système articulé à masselottes aptes à libérer une pièce de verrouillage.Such means comprise for example a calibrated spring, which when the helmet acceleration exceeds a predetermined threshold (typically 10 G), releases the visor, or an articulated system with weights able to release a locking piece.

Ainsi, en cas d'éjection non préparée, la visière 200 retombe automatiquement en position baissée pour protéger le visage du pilote.Thus, in case of unprepared ejection, the visor 200 automatically falls down to protect the face of the driver.

Les figures 3 et 4 représentent de manière schématique un casque aéronautique conforme à un deuxième mode de réalisation de l'invention.The figures 3 and 4 schematically represent an aeronautical helmet according to a second embodiment of the invention.

Le casque comprend une coque 100 destiné à protéger la tête d'un pilote, une visière 200 munie d'un dispositif de vision nocturne 201 et un dispositif de fixation 400 de la visière 200 sur la coque 100.The helmet comprises a hull 100 for protecting the head of a pilot, a visor 200 provided with a night vision device 201 and a fastener 400 of the visor 200 on the hull 100.

Sur les figures 3 et 4, le casque est représenté en vue de profil et une partie seulement du dispositif de fixation 400 de la visière 200 est visible. Cependant, on comprendra que le dispositif de fixation 400 de la visière 200 est symétrique par rapport au plan des figures (qui correspond plan sagittal de la tête du pilote).On the figures 3 and 4 , the helmet is shown in profile view and only part of the fixing device 400 of the visor 200 is visible. However, it will be understood that the fixing device 400 of the visor 200 is symmetrical with respect to the plane of the figures (which corresponds to the sagittal plane of the pilot's head).

Le dispositif de fixation 400 de la visière 200 sur la coque 100 est apte à permettre un mouvement de la visière 200 par rapport à la coque 100 entre une position baissée (représentée sur la figure 3) et une position relevée ou position d'attente (représentée sur la figure 4).The fixing device 400 of the visor 200 on the shell 100 is able to allow a movement of the visor 200 with respect to the shell 100 between a lowered position (shown in FIG. figure 3 ) and a raised position or waiting position (shown on the figure 4 ).

Le dispositif de fixation 400 comprend un support 410 apte à être fixé sur la coque 100, un bandeau 420 apte à recevoir la visière 200, un premier élément de liaison 430 entre le support 410 et le bandeau 420 et un deuxième élément de liaison 440 entre le support 410 et le bandeau 420.The fixing device 400 comprises a support 410 capable of being fixed on the shell 100, a strip 420 capable of receiving the visor 200, a first connecting element 430 between the support 410 and the strip 420 and a second connecting element 440 between the support 410 and the headband 420.

Le bandeau 420 est muni de moyens de fixation 421 destinés à recevoir de manière amovible des moyens de fixation 221 complémentaire de la visière 200 pour fixer la visière 200 sur le bandeau 420.The headband 420 is provided with fixing means 421 for removably receiving fixing means 221 complementary to the visor 200 for fixing the visor 200 on the headband 420.

Le support 410 est apte à être fixé de manière amovible sur la coque 100 du casque. Les moyens de fixation du support 410 sur la coque 100 seront décrits plus en détail en référence à la figure 5.The support 410 is adapted to be removably attached to the shell 100 of the helmet. The fixing means of the support 410 on the shell 100 will be described in more detail with reference to the figure 5 .

Le premier et le deuxième éléments de liaison 430 et 440 comprennent respectivement une première bielle 431 et une deuxième bielle 441 s'étendant entre le support 310 et le bandeau 320.The first and second connecting elements 430 and 440 respectively comprise a first connecting rod 431 and a second connecting rod 441 extending between the support 310 and the strip 320.

La première bielle 431 est montée à rotation par rapport au support 310 autour d'un premier axe de rotation 432 situé au niveau d'une première extrémité de la bielle. D'autre part, la bielle 431 est montée à rotation par rapport au bandeau 320 autour d'un deuxième axe de rotation 433 situé au niveau d'une deuxième extrémité de la bielle 431 et parallèle au premier axe de rotation 432.The first link 431 is rotatably mounted relative to the support 310 about a first axis of rotation 432 located at a first end of the rod. On the other hand, the connecting rod 431 is rotatably mounted relative to the strip 320 around a second axis of rotation 433 located at level of a second end of the connecting rod 431 and parallel to the first axis of rotation 432.

De même, la deuxième bielle 441 est montée à rotation par rapport au support 310 autour d'un premier axe de rotation 442 situé au niveau d'une première extrémité de la bielle. D'autre part, la bielle 441 est montée à rotation par rapport au bandeau 320 autour d'un deuxième axe de rotation 443 situé au niveau d'une deuxième extrémité de la bielle 441 et parallèle au premier axe de rotation 442.Similarly, the second connecting rod 441 is rotatably mounted relative to the support 310 about a first axis of rotation 442 located at a first end of the rod. On the other hand, the rod 441 is rotatably mounted relative to the strip 320 around a second axis of rotation 443 located at a second end of the connecting rod 441 and parallel to the first axis of rotation 442.

Les axes de rotation 442 et 443 de la deuxième bielle 441 sont distincts des axes de rotation 432 et 433 de la première bielle 431.The axes of rotation 442 and 443 of the second connecting rod 441 are distinct from the axes of rotation 432 and 433 of the first link 431.

En outre, les premier et deuxième axes de rotation 432, 433, 442 et 443 s'étendent dans une direction générale perpendiculaire au plan de symétrie du casque.In addition, the first and second axes of rotation 432, 433, 442 and 443 extend in a general direction perpendicular to the plane of symmetry of the helmet.

On considère que la longueur L de la première bielle 431 est égale à la distance entre les axes de rotation 432 et 433. On considère que la longueur l de la deuxième bielle 441 est égale à la distance entre les axes de rotation 442 et 443. La longueur L de la première bielle 431 est supérieure à la longueur l de la deuxième bielle 441.It is considered that the length L of the first link 431 is equal to the distance between the axes of rotation 432 and 433. It is considered that the length l of the second link 441 is equal to the distance between the axes of rotation 442 and 443. The length L of the first connecting rod 431 is greater than the length l of the second connecting rod 441.

En outre, les axes 432 et 442 sont excentrés par rapport à l'axe 141. Plus précisément, les axes 432 et 442 sont excentrés vers l'avant du casque.In addition, the axes 432 and 442 are eccentric with respect to the axis 141. More specifically, the axes 432 and 442 are eccentric towards the front of the helmet.

En position baissée (représentée sur la figure 3), la visière 200 est disposée devant les yeux du pilote de sorte que le pilote visualise l'environnement extérieur à travers le dispositif de vision nocturne 201.In the down position (shown on the figure 3 ), the visor 200 is disposed in front of the eyes of the pilot so that the pilot visualizes the outside environment through the night vision device 201.

Lorsque le pilote ne souhaite plus utiliser le dispositif de vision nocturne 201, le pilote peut relever la visière 200 pour disposer la visière 200 au-dessus de son visage, en position relevée (représentée sur la figure 4).When the pilot no longer wishes to use the night-vision device 201, the pilot can raise the visor 200 to place the visor 200 above his face, in the raised position (shown in FIG. figure 4 ).

Lors du mouvement de la visière 200 entre la position baissée et la position relevée, la visière pivote autour du premier axe 432, ce qui permet un dégagement de la visière 200 par rapport au visage du pilote, vers l'avant du casque.During the movement of the visor 200 between the lowered position and the raised position, the visor pivots about the first axis 432, which allows a release of the visor 200 relative to the pilot's face, towards the front of the helmet.

D'autre part, la visière 200 pivote également autour du deuxième axe de rotation 433 et est guidée lors de son mouvement par la deuxième bielle 441. La deuxième bielle 441 permet un basculement de la visière 200 vers l'arrière du casque pour maintenir la visière à proximité de la coque 100.On the other hand, the visor 200 also pivots about the second axis of rotation 433 and is guided during its movement by the second link 441. The second link 441 allows a tilting of the visor 200 towards the rear of the helmet to maintain the visor near the hull 100.

Le dispositif de fixation 400 comprend des moyens pour verrouiller la visière 200 en position relevée, les moyens étant aptes à libérer la visière en cas d'éjection non préparée.The fixing device 400 comprises means for locking the visor 200 in the raised position, the means being able to release the visor in case of unprepared ejection.

En cas d'éjection non préparée, la visière 200 retombe automatiquement en position baissée pour protéger le visage du pilote.In case of unprepared ejection, the visor 200 automatically drops down to protect the face of the driver.

La figure 5 représente de manière schématique des moyens de fixation du support 400 sur une coque 100 de casque.The figure 5 schematically shows means for fixing the support 400 on a helmet shell 100.

Sur la figure 5, une partie seulement des moyens de fixation est visible. Cependant, on comprendra que les moyens de fixation sont symétriques par rapport au plan de symétrique du casque 100 (qui correspond plan sagittal de la tête du pilote).On the figure 5 only a part of the fastening means is visible. However, it will be understood that the fixing means are symmetrical with respect to the symmetrical plane of the helmet 100 (which corresponds to the sagittal plane of the pilot's head).

Les moyens de fixation comprennent une vis 401, un pion 402 cylindrique, un élément en forme de U 404 et un élément de verrouillage 405.The fastening means comprise a screw 401, a cylindrical pin 402, a U-shaped member 404 and a locking member 405.

Le pion 402 cylindrique est destiné à être fixé sur la coque 100 du casque par l'intermédiaire de la vis 401.The cylindrical pin 402 is intended to be fixed on the shell 100 of the helmet by means of the screw 401.

La vis 401 est apte à être reçue dans un orifice 101 ménagé dans la coque 100. Sur les casques de type LA 100, deux orifices sont déjà prévus sur la coque pour le montage à rotation d'une visière claire. Ces orifices peuvent être utilisés pour fixer le support 400 à la coque 100. Ainsi le dispositif de fixation ne nécessite pas une modification de la coque du casque.The screw 401 is adapted to be received in an orifice 101 formed in the shell 100. LA 100 type helmets, two orifices are already provided on the shell for the rotational mounting of a clear visor. These orifices can be used to fix the support 400 to the hull 100. Thus the fixing device does not require a modification of the hull of the helmet.

Le pion 402 présente une rainure 403 radiale destinée à recevoir l'élément en forme de U 404. L'élément en forme de U 404 est apte à recevoir entre ses deux branches le pion 402.The pin 402 has a radial groove 403 for receiving the U-shaped element 404. The U-shaped element 404 is adapted to receive between its two branches the pin 402.

L'élément de verrouillage 405 est monté à rotation par rapport à l'élément en forme de U 404 et est apte à venir fermer l'élément en forme de U 404 pour maintenir le pion 402 entre les branches du U.The locking member 405 is rotatably mounted relative to the U-shaped member 404 and is adapted to engage the U-shaped member 404 to hold the pin 402 between the legs of the U.

Les moyens de fixation du support 400 sur la coque 100 comprennent en outre un élément de fixation 407 apte à être inséré dans une rainure 140 de la coque 100.The fixing means of the support 400 on the shell 100 further comprise a fastening element 407 adapted to be inserted into a groove 140 of the shell 100.

Le support 400 est donc apte à être fixé en trois points sur la coque du casque.The support 400 is therefore able to be fixed at three points on the shell of the helmet.

Les supports 300 et 400 sont totalement indépendants de la coque du casque. Dans le cas d'un caque de type LA 100, ces supports peuvent être fixés sans modifier la coque du casque, ce qui permet d'équiper le casque avec le dispositif de l'invention en préservant l'intégrité de la coque.The supports 300 and 400 are completely independent of the shell of the helmet. In the case of a type LA 100, these supports can be fixed without modifying the shell of the helmet, which allows to equip the helmet with the device of the invention while preserving the integrity of the hull.
