Description

PERFECTIONNEMENT POUR DISPOSITIF DE COMMUNICATION DI ) TYPE ELECTROACOUSTIQUE DESTINE A EQUIPER UN CASQUE DE PROTECTIONIMPROVEMENT FOR A COMMUNICATION DEVICE DI) ELECTROACOUSTIC TYPE FOR EQUIPPING A PROTECTIVE HELMET
La présente invention concerne un dispositif de communication électroacoustique et plus particulièrement un dispositif pour casque de protection ainsi qu'un casque équipé d'un tel dispositifThe present invention relates to an electroacoustic communication device and more particularly a device for a protective helmet as well as a helmet equipped with such a device.
Les casques de protection sont depuis fort longtemps d'un usage courant dans différents domaines, soit à titre professionnel, comme c'est le cas pour les militaires, les gendarmes ou les pompiers, soit à titre civil ou prive, comme cela est le cas pour les utilisateurs de motos, de voitures de rallye ou de course On connaît aussi des casques qui sont équipés d'un moyen de communication permettant à son utilisateur de communiquer avec un autre utilisateur portant un casque similaire On peut à cet égard citer les casques décrits dans les demandes de brevet françaises n° 2 289 072, n° 2 502 372, ou encore n° 2 471 112, qui sont équipés de dispositifs électroacoustiques assez complexes et peu satisfaisants En effet, les casques tels que décrits dans l'art antérieur ne peuvent pas être portés dans des conditions difficiles d'utilisation comme, par exemple, par des pompiers qui font des interventions délicates II a été déjà proposé un perfectionnement qui est décrit dans la demande de brevet française n° 2 565 057 déposée par la demanderesse, selon laquelle la liaison entre le casque et le dispositif électroacoustique est amovible tandis que le capteur est un ostéomicrophone porté par un bras II est, dans cette même demande de brevet, proposé un autre dispositif électroacoustique dont la liaison avec le casque est aussi amovible, mais selon lequel le capteur est un simple microphone porte par un brasProtective helmets have long been in common use in various fields, either professionally, as is the case for the military, gendarmes or firefighters, or civil or private, as is the case for users of motorcycles, rally or racing cars We also know helmets which are equipped with a means of communication allowing its user to communicate with another user wearing a similar helmet We can mention in this regard the helmets described in French patent applications No. 2 289 072, No. 2 502 372, or also No. 2 471 112, which are equipped with fairly complex and unsatisfactory electroacoustic devices In fact, the headsets as described in the prior art cannot be worn in conditions which are difficult to use, such as, for example, by firefighters who perform delicate operations. An improvement has already been proposed which is described it in French patent application No. 2,565,057 filed by the applicant, according to which the connection between the headset and the electroacoustic device is removable while the sensor is an osteomicrophone carried by an arm II is, in this same patent application , proposed another electroacoustic device whose connection with the headset is also removable, but according to which the sensor is a simple microphone carried by an arm
Mais tous ces dispositifs connus présentent un certain nombre d'inconvénients et notamment celui d'être encombrants, peu pratiques, ainsi que relativement complexes et fragiles La présente invention se veut donc de résoudre les inconvénients cités précédemment en proposant une nouveau dispositif particulièrement simple, fiable et pratiqueBut all of these known devices have a certain number of drawbacks, in particular that of being bulky, impractical, as well as relatively complex and fragile The present invention therefore aims to solve the drawbacks mentioned above by proposing a new device which is particularly simple, reliable and practical.
Ainsi le dispositif de communication du type électroacoustique pour casque de protection selon l'invention, comprend un capteur, tel qu'un microphone, et un écouteui, et est caractéπsé en ce que ledit capteur et l'écouteur sont disposés dans un boîtier et en ce qu'il est prévu des moyens de liaison destinés à fixer ledit boîtier au casque, lesdits moyens constituant une liaison amovibleThus the electroacoustic type communication device for protective helmet according to the invention comprises a sensor, such as a microphone, and a headset, and is characterized in that said sensor and the earpiece are arranged in a housing and in what is provided connecting means for fixing said housing to the helmet, said means constituting a removable connection
Selon une caractéristique complémentaire, le boîtier est destiné à être fixé à l'intérieur du casque dans la zone occupée par l'oreille de l'utilisateur. A cet effet, le boîtier comprend un prolongement formant une patte de liaison destinée à être engagée dans une glissière latérale solidaire du casque ayant une forme complémentaire.According to an additional characteristic, the box is intended to be fixed inside the helmet in the area occupied by the user's ear. To this end, the housing includes an extension forming a connecting tab intended to be engaged in a lateral slide secured to the helmet having a complementary shape.
Par ailleurs, le casque est, par exemple, du type comprenant une coiffe deformable comprenant un bandeau retenant une paroi deformable ou similaire, ledit bandeau étant fixé au casque par au moins la glissière latérale retenant le dispositif de communication, tandis que la glissière latérale est solidaire d'une pièce frontale de support fixée à la coque externe principale du casqueFurthermore, the helmet is, for example, of the type comprising a deformable cap comprising a strip retaining a deformable wall or the like, said strip being fixed to the helmet by at least the lateral slide retaining the communication device, while the lateral slide is secured to a front support piece fixed to the main outer shell of the helmet

The outer shell (31) constitutes a cavity comprising, for example, a cap (41) and other elements such as, for example, neck cushions (42) as well as a cap (43) The latter is, for example , consisting of a layer of foam which is, for example, bonded to the inner face (44) of the shell The deformable cap (41) allows, on the one hand, the adaptation of the helmet to the volume and the shape of the head of the user and, on the other hand, to maintain a space between the latter and the internal face of the shell, which moreover includes, and in a manner known per se, a retaining chin strap (45)
La coiffe deformable (41) se compose d'un bandeau rembourré de tour de tête (46) et d'une paroi deformable (47) comme, par exemple, une résille textile destinée à prendre appui sur la tête de l'utilisateur Ladite coiffe ainsi constituée est fixée à l'intérieur du casque par son bandeau sur une pièce frontale de support (48) disposée et fixée à l'intérieur de la coque pour s'étendre depuis l'avant et partiellement vers l'arrière en suivant le profil de la face interne de la paroi de la coque Cette pièce frontale de suppoit (48) est constituée par une paroi courbe en matière plastique dont la partie frontale s'étend partiellement vers le haut et dont les extrémités des parties latérales (49) sont fixées aux portions latérales des parois (37) de la coque, par exemple, pai des vis (50) ou similaire. La fixation du bandeau (46) sur la pièce frontale se fait grâce à des boutons (51) faisant saillie du bandeau pour être engagés et retenus dans des glissières borgnes correspondantes (52, 53) réalisées dans la pièce frontale (48) Les deux glissières frontales (52) ont une longueur suffisante pour recevoir et retenir correctement les boutons d'accrochage du bandeau correspondant, tandis que l'une au moins des glissières latérales (53) est prolongée vers le bas pour recevoir le bouton du bandeau correspondant et assurer la retenue et la liaison du dispositif de communication (1) selon l'invention Notons que les glissières latérales (53) sont disposées à l'intérieur du casque et latéralement dans les zones latérales occupées par les oreilles de l'utilisateur du casque.The deformable cap (41) consists of a padded headband (46) and a deformable wall (47) such as, for example, a textile mesh intended to bear on the head of the user. thus constituted is fixed inside the helmet by its strip on a front support piece (48) arranged and fixed inside the shell to extend from the front and partially towards the rear following the profile from the inside of the hull wall This front face piece (48) is constituted by a curved plastic wall, the front part of which extends partially upwards and the ends of the side parts (49) of which are fixed to the side portions of the walls (37) of the shell, for example, by screws (50) or the like. The fixing of the strip (46) on the front piece is done by buttons (51) projecting from the strip to be engaged and retained in corresponding blind slides (52, 53) made in the front piece (48) The two slides frontal (52) have a sufficient length to receive and correctly retain the buttons for hooking the corresponding strip, while at least one of the lateral slides (53) is extended downwards to receive the button for the corresponding strip and to ensure the retention and connection of the communication device (1) according to the invention Note that the side rails (53) are arranged inside the helmet and laterally in the lateral areas occupied by the ears of the helmet user.
Selon l'invention, le boîtier de communication (4) est disposé à l'intérieur du casque contre les portions latérales des parois (37) de la coque dans la zone occupée par l'oreille du porteur du casque A cet effet, ledit boîtier (4) est retenu dans le casque par coopération de sa patte de liaison (5) avec la glissière latérale (53), comme, par exemple, et tel qu'illustré avec la glissière latérale droite. Ainsi, le prolongement de boîtier (5) est engagé dans la glissière.According to the invention, the communication box (4) is arranged inside the helmet against the lateral portions of the walls (37) of the shell in the area occupied by the ear of the wearer of the helmet. For this purpose, said box (4) is retained in the helmet by cooperation of its connecting tab (5) with the side slide (53), as, for example, and as illustrated with the right side slide. Thus, the housing extension (5) is engaged in the slide.
En position d'utilisation dans le casque, le capteur microphonique (2) est disposé au-dessus de l'écouteur (3)In the position of use in the headset, the microphone sensor (2) is arranged above the earpiece (3)
Par ailleurs, le câble de connexion (8) est relié au casque dans sa partie médiane (80) grâce au dispositif d'accrochage (15) destiné à venir en prise avec les moyens d'accrochage (450) de la jugulaire (45) Le dispositif d'accrochage (15) comprend une première pièce (15a) sur laquelle est articulée une deuxième pièce (15b) qui comprend une gorge d'accrochage (150) dans laquelle est engagé le câble de connexion (8, 80). Ainsi, ce dernier longe la bordure inférieure (40) avant de faire saillie vers l'avant (AV). Il va de soi que l'on ne soitn ait pas du cadie de l'invention quel que soit le type de casque de protection utilisé Pai ailleurs, on ne sortirait pas non plus du cadre de l'invention si le boîtier (4) était fixé au casque, mais extérieurement comme, pai exemple, sur sa paroi extérieure (33) au niveau des portions latérales des parois, au niveau des zones occupées par les oreilles II va de soi aussi que l'on pourrait utiliser tous autres moyens de liaison que celui décrit précédemment comme, par exemple, par collage, vissage et autreFurthermore, the connection cable (8) is connected to the helmet in its middle part (80) by means of the attachment device (15) intended to come into engagement with the attachment means (450) of the chin strap (45). The hooking device (15) comprises a first part (15a) on which a second part (15b) is articulated which comprises a hooking groove (150) in which the connection cable (8, 80) is engaged. Thus, the latter runs along the lower edge (40) before projecting forward (AV). It goes without saying that we are not within the scope of the invention whatever the type of protective helmet used elsewhere, nor would we depart from the scope of the invention if the housing (4) was attached to the helmet, but externally as, for example, on its outer wall (33) at the side portions of the walls, at the areas occupied by the ears II goes without saying also that one could use any other means of connection than the one described above as, for example, by gluing, screwing and other
On notera que les moyens de liaison du boîtier sont des moyens constituant une liaison amovible permettant un montage et un démontage manuel et facile que l'utilisateur peut faire sans qu'il lui soit nécessaire d'avoir un outillage particulierIt will be noted that the connection means of the housing are means constituting a removable connection allowing manual and easy assembly and disassembly that the user can do without it being necessary for him to have any particular tool.
Bien entendu, l'invention n'est pas limitée aux modes de réalisation décrits et représentés à titre d'exemples, mais elle comprend aussi tous les équivalents techniques ainsi que leurs combinaisons Of course, the invention is not limited to the embodiments described and represented by way of examples, but it also includes all the technical equivalents and their combinations
