• the box is intended to be fixed inside the helmet in the area occupied by the user's ear.
• 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.
• 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
• Figure 1 is a perspective view showing the entire communication device and an example of protective helmet for which it is intended
• Figure 2 is an exploded perspective view illustrating the various elements constituting the communication device of the invention.
• Figure 3 is a side view with partial airachements of the protective helmet equipped with the communication device of the invention.
• Figure 4 is a perspective view of the helmet with its communication device
• Figure 5 is a detailed perspective view showing more particularly the retention of the connection cable.
• the communication device (1) is of the electroacoustic type intended for transmitting and / or receiving messages allowing the user to communicate with, for example, another user wearing a similar device and comprises a sensor (2) such as a similar microphone and at least one earpiece (3).
• the device comprises a housing (4) in which is disposed, on the one hand, the earpiece (3) and, on the other hand, the microphone (2). Furthermore, the housing (4) comprises an extension forming a connection tab (5) making it possible to fix the device in a protective helmet.
• connection cable (8) which makes it possible to connect the electroacoustic device to the elements of the known external equipment (9) in itself which comprises a transceiver station (10) and a control unit (11) disposed between two connecting cables (12a, 12b), a first electrical cable (12a) connected to the transceiver (10) to a connection plug (13) and a second electric cable (12b) connected to the connection (7) of the device (1) by means of a self-breaking safety connection (14).
• the housing (4) comprises a housing body (16) closed by a cover (17) fixed to said body (16) by clipping or by means of an assembly
• Said housing body (16) has the general shape of a triangle and comprises two housings (19, 20), a first cylindrical housing (19) intended to receive the microphone sensor (2) and a second cylindrical housing (20) of smaller diameter intended to receive the earpiece (3) Furthermore, and advantageously, these two housings are connected to each other to form a common hollow housing (21) produced in the housing body and which is open outwards via a lateral opening (22) intended for the passage and retention of the connection cable (8).
• the upper wall of the housing body (16) comprises the extension (5) mentioned above. The latter is integral with the housing body and has the shape of a flat extending upward and whose width and length allow its engagement in a corresponding slide disposed inside the protective helmet.
• the cover (17) consists of a generally shaped plate identical to the housing body (16) and comprises two holes (23, 24), a first hole (23) arranged at the microphone (2) and a second hole ( 24) arranged at the earpiece (3).
• two discs (200, 300) of deformable foam intended to be arranged at the bottom of the housing (19, 20) between the microphone (2) and the bottom wall (160) of the housing body (16 ), as well as between the earpiece (3) and said bottom wall.
• the communication device of the invention is intended to equip a protective helmet (30) which may be of any type II.
• a helmet will therefore be described by way of non-limiting example of the type such as, for example, that used by the firefighters and comprising a main external shell (31) protecting the skull and the neck of the user and having a front facial opening (32) in the area occupied by the face proper of the latter
• the shell is made of rigid material and can be of any suitable material such as plastic, steel, aluminum or other material.
• composite of the type comprising a stack of layers of reinforcing fibers, impregnated and bonded together by a resin mat ⁇ ce
• said external shell is constituted by a substantially spherical wall (33) comprising several wall portions, namely, an upper front portion of wall (34) extended rearwards by an upper rear wall portion (35), itself extended downwards by a lower rear wall portion (36) and comprises, moreover, two lateral wall portions (37 )
• the upper front portion (34) corresponds to the area occupied by the front of the utihsate ⁇ i and is limited by the upper border (38) of the facial opening (32) which, for its part, is limited laterally by two borders lateral (39)
• the upper rear wall portion (35) corresponds to the area occupied by the user's skull, while the lower rear wall portion (36) corresponds to the occupied area by the user's neck Let us add to this that the wall (33)
• the lateral wall portions (37) correspond to the areas occupied by the ears of the user and are bounded forwards by the corresponding lateral border (39) of the facial opening (32) and downwards by the front ends of the lower border (40).
• 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)
• 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.
• a deformable wall (47) such as, for example, a textile mesh intended to bear on the head of the user.
• 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
• the side rails (53) are arranged inside the helmet and laterally in the lateral areas occupied by the ears of the helmet user.
• 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.
• 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.
• the housing extension (5) is engaged in the slide.
• the microphone sensor (2) is arranged above the earpiece (3)
• 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.
• the latter runs along the lower edge (40) before projecting forward (AV).
• 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.
