Dans une variante de réalisation, la base 10 comporte un élément de liaison entre les deux parties qui vient se positionner en arrière du cou du porteur lors d'une mise en place du casque de protection d'urgence 1 selon l'invention. Chacune des parties de la base 10 est de forme triangulaire en vue de côté comme illustré aux figures 1 et 2.The emergency protective helmet 1 according to the invention comprises a base 10 which, once in place on a wearer, comes to rest on the shoulders 3 of the wearer. The base 10 is, for example, in two separate parts which are positioned on either side of a head 2 of the wearer on the shoulders 3 of the latter. In an alternative embodiment, the base 10 comprises a connecting element between the two parts which is positioned behind the neck of the wearer when putting on the emergency protective helmet 1 according to the invention. Each of the parts of the base 10 is triangular in shape in side view as illustrated in figures 1 and 2 .

D'autre part, le casque de protection d'urgence 1 selon l'invention comprend un support de rangement tour de cou 20 qui est monté mobile sur la base 10 au moyen d'un dispositif de réglage en position 40,41,42 dudit support de rangement tour de cou 20 par rapport à ladite base 10. Le support de rangement tour de cou 20 comporte, sur une partie avant, une boucle d'attache rapide 21 et sur une partie arrière un espace de rangement 22 qui tombe en arrière des épaules 3 et du cou du porteur. Cela donne, en vue de côté illustrée aux figures 1 et 2, une forme générale de haricot.On the other hand, the emergency protective helmet 1 according to the invention comprises a neck storage support 20 which is movably mounted on the base 10 by means of an adjustment device in position 40,41,42 of said neck storage support 20 relative to said base 10. The neck storage support 20 comprises, on a front part, a quick-release buckle 21 and on a rear part a storage space 22 which falls behind of the shoulders 3 and neck of the wearer. This gives, in side view illustrated to figures 1 and 2 , a general form of bean.

Le dispositif de réglage en position 40,41,42 comporte, ici, une rainure longitudinale 40 ménagée dans l'une des parties de la base 10. La rainure longitudinale 40 est orientée de sorte à s'étendre sensiblement selon une direction allant depuis les épaules 3 vers la tête 2 du porteur. Cette direction est sensiblement verticale. Par ailleurs, le dispositif de réglage en position comporte un axe 41 monté sur le support de rangement tour de cou 20. L'axe 41 est destiné à coopérer à coulissement avec la rainure longitudinale 40 qui lui est associée afin de réaliser un montage mobile à translation entre le support de rangement tour de cou 20 et la base 10 et de permettre un réglage de la position 42 du support de rangement tour de cou 20 par rapport à la base 10. Des moyens de verrouillage de la position 42 sont prévus. Cela permet d'adapter le casque de protection d'urgence 1 selon l'invention à une morphologie du porteur.The adjustment device in position 40,41,42 comprises, here, a longitudinal groove 40 formed in one of the parts of the base 10. The longitudinal groove 40 is oriented so as to extend substantially in a direction from the sides. shoulders 3 towards the head 2 of the wearer. This direction is substantially vertical. Furthermore, the position adjustment device comprises an axis 41 mounted on the neck strap storage support 20. The axis 41 is intended to cooperate slidingly with the longitudinal groove 40 which is associated with it in order to achieve a movable mounting. translation between the neck storage support 20 and the base 10 and to allow adjustment of the position 42 of the neck storage support 20 relative to the base 10. Position 42 locking means are provided. This makes it possible to adapt the emergency protective helmet 1 according to the invention to the morphology of the wearer.

Le casque de protection d'urgence 1 selon l'invention comporte aussi une série d'éléments incurvés 31,32,33,34. Les éléments incurvés 31,32,33,34, ici au nombre de quatre, sont montés mobiles à rotation avec le support de rangement tour de cou 20 et les uns avec les autres au niveau de leurs extrémités 35. La rotation s'effectue autour d'un axe 30. Cela permet à l'ensemble des éléments incurvés 31,32,33,34 de passer d'une première position déployée fonctionnelle illustrée à la figure 2 à une deuxième position reployée non fonctionnelle illustrée à la figure 1. Dans la deuxième position reployée non fonctionnelle, l'ensemble des éléments incurvés sont reçus dans l'espace de rangement 22 du support de rangement tour de cou 20 : ils sont ainsi logés dans ledit support de rangement tour de cou 20. Dans la première position déployée fonctionnelle, l'ensemble des éléments incurvés 31,32,33,34 est déployé autour de la tête 2 du porteur de sorte à former une structure de protection autour du crâne du porteur. Un ensemble de tubes souples 50 relient entre eux les éléments incurvés 31,32,33,34 de l'ensemble des éléments incurvés. D'autre part, le casque de protection d'urgence 1 selon l'invention comprend une toile souple 36 reliant, elle aussi, les éléments incurvés 31,32,33,34 entre eux. Ici les éléments incurvés 31,32,33,34 sont des arceaux rigides.The emergency protective helmet 1 according to the invention also comprises a series of curved elements 31,32,33,34. The curved elements 31, 32, 33, 34, here four in number, are rotatably mounted with the neck storage support 20 and with each other at their ends 35. The rotation takes place around of an axis 30. This allows all of the curved elements 31, 32, 33, 34 to move from a first functional deployed position illustrated in figure 2 to a second non-functional stowed position shown in figure 1 . In the second non-functional folded-up position, all of the curved elements are received in the storage space 22 of the neck storage support 20: they are thus housed in said neck storage support 20. In the first position deployed functionally, all of the curved elements 31, 32, 33, 34 are deployed around the head 2 of the wearer so forming a protective structure around the wearer's skull. A set of flexible tubes 50 interconnect the curved elements 31, 32, 33, 34 of the set of curved elements. On the other hand, the emergency protective helmet 1 according to the invention comprises a flexible canvas 36 also connecting the curved elements 31, 32, 33, 34 together. Here the curved elements 31, 32, 33, 34 are rigid hoops.

Additionnellement, le casque de protection d'urgence 1 selon l'invention comprend, de part et d'autre au droit des épaules 3 du porteur, deux coussins gonflables positionnés dans le support de rangement tour de cou 20.

Le porteur met en place le casque de protection d'urgence 1 selon l'invention autour de son cou, la base 10 venant en appui sur les épaules 3 du porteur. Le porteur règle ensuite une position 42 du support de rangement tour de cou 20 en hauteur par rapport à la base 10 à l'aide du dispositif de réglage en position 40,41,42. Préalablement ou postérieurement à ce réglage en position, le porteur du casque de protection d'urgence 1 selon l'invention ferme sur le devant la boucle d'attache rapide 21. Dès lors, les moyens formant interrupteur envoient un signal de mise en place du casque de protection d'urgence 1 selon l'invention autour du cou du porteur à l'unité de contrôle et de pilotage 60. L'unité de contrôle et de pilotage 60 initie alors une procédure 110 de vérification de l'ensemble des éléments du casque de protection d'urgence 1 selon l'invention auxquels elle est connectée. Si la procédure de vérification ne décèle aucune anomalie ou problème, l'unité de contrôle et de pilotage 60 se met en mode « armé » 120, confirmé par une émission d'un signal sonore et/ou visuel. Une fois armée, l'unité de contrôle et de pilotage 60 analyse 130 les informations transmises par l'ensemble des capteurs, comme les informations du capteur de vitesse 160 et les informations du capteur de position/angle 170. Selon les informations reçues, un déclenchement 140 de la cartouche 70 est activé par l'unité de contrôle et de pilotage 60 si une variation brutale des informations envoyées par les capteurs de position/angle et/ou de vitesse est détectée, signifiant soit une chute, soit un choc. Une fois la cartouche 70 activée, les deux coussins gonflables se déploient, déplaçant verticalement vers le haut le support de rangement tour de cou 20, puis l'ensemble des tubes souples 50 se déploient à leur tour. Le casque de protection d'urgence 1 selon l'invention passe 150 alors dans sa position fonctionnelle déployée, entourant la tête 2 du porteur.With reference to the figure 4 , we will briefly describe an operation of the emergency protective helmet 1 according to the invention which comes to be described above. The wearer places the emergency protective helmet 1 according to the invention around his neck, the base 10 resting on the shoulders 3 of the wearer. The wearer then adjusts a position 42 of the neck strap storage support 20 in height relative to the base 10 using the adjustment device in position 40,41,42. Before or after this position adjustment, the wearer of the emergency protective helmet 1 according to the invention closes the quick-release buckle 21 on the front. From then on, the switch-forming means send a signal to put the device in place. emergency protective helmet 1 according to the invention around the neck of the wearer to the control and piloting unit 60. The control and piloting unit 60 then initiates a procedure 110 for checking all the elements of the emergency protective helmet 1 according to the invention to which it is connected. If the verification procedure does not detect any anomaly or problem, the control and piloting unit 60 goes into “armed” mode 120, confirmed by the emission of an audible and / or visual signal. Once armed, the control and pilot unit 60 analyzes 130 the information transmitted by all the sensors, such as the information from the speed sensor 160 and the information from the position / angle sensor 170. According to the information received, a trigger 140 of the cartridge 70 is activated by the control and pilot unit 60 if a sudden variation in the information sent by the position / angle and / or speed sensors is detected, signifying either a fall or a shock. Once the cartridge 70 is activated, the two airbags deploy, moving the neck storage support 20 vertically upwards, then all of the flexible tubes 50 are deployed in turn. The emergency protective helmet 1 according to the invention then passes 150 into its deployed functional position, surrounding the head 2 of the wearer.

Le fait d'utiliser des éléments incurvés 31-34 rigides permet d'assurer en permanence une structure rigide protectrice autour de la tête 2 du porteur, bien après que la cartouche 70 soit déclenchée.The use of rigid curved elements 31-34 makes it possible to permanently ensure a rigid protective structure around the head 2 of the wearer, long after the cartridge 70 is triggered.

Bien entendu, il est possible d'apporter à l'invention de nombreuses modifications sans pour autant sortir du cadre de celle-ci.Of course, it is possible to make numerous modifications to the invention without departing from the scope thereof.
