Description

La présente invention concerne un casque de protection, et plus particulièrement son dispositif d'accrochage du masque respiratoire.The present invention relates to a protective helmet, and more particularly its device for attaching the respiratory mask.

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 privé.Protective helmets have been used for a very long time current in different fields either professionally as is the case for soldiers, gendarmes or firefighters, either civil or private.

On connaít, par exemple, le casque divulgué par le brevet européen 0 105 813 qui montre un casque utilisable avec un masque respiratoire du type selon lequel ce dernier est retenu à la coque du casque par deux bras latéraux comprenant à leur extrémité des crochets destinés à venir en prise de façon amovible avec deux crans d'accrochage réalisés sur les parois latérales du casque. Ce type de disposition est particulièrement pratique et utilisé maintenant par de nombreux sapeurs-pompiers. Toutefois, malgré l'effet télescopique des bras latéraux, destiné à donner au masque une pression sur le visage à la fois sûre et confortable, il arrive que dans certains cas l'adaptation automatique ne soit pas correcte. We know, for example, the helmet disclosed by the patent European 0 105 813 which shows a helmet usable with a mask respiratory of the type according to which the latter is retained in the shell of the helmet by two lateral arms comprising at their ends hooks intended for removably engaged with two hooking notches made on the side walls of the helmet. This type of arrangement is particularly practical and now used by many firefighters. However, despite the telescopic effect of the side arms, intended to give in the mask pressure on the face both safe and comfortable, it happens that in some cases the automatic adaptation is not correct.

On connaít par le brevet européen EP-A-0 336 834 un dispositif de retenue d'un masque respiratoire, constitué par des pièces d'accrochage fixées, sur chacune des parois latérales du casque, de façon à pouyvoir en régler la position. Toutefois le réglage en position permet seulement d'en modifier la position verticale, ce qui ne solutionne bien évidemment pas le problème posé précédemment. European patent EP-A-0 336 834 discloses a device for restraint of a respiratory mask, consisting of attachment pieces fixed, on each of the side walls of the helmet, so as to be able to adjust the position. However the position adjustment only allows change the vertical position, which obviously does not solve the problem previously posed.

La présente invention entend donc résoudre l'inconvénient évoqué précédemment en permettant d'adapter la position du masque respiratoire, d'une part, aux dimensions du casque, et notamment aux dimensions de la coque et/ou des réglages des éléments internes tels que bandeau et coiffe-interne, et d'autre part, aux dimensions de la tête et notamment du visage de l'utilisateur. A cet effet, le casque de l'invention comprend des moyens de réglage en position des moyens d'accrochage du masque. The present invention therefore intends to solve the drawback mentioned previously by allowing to adapt the position of the mask on the one hand, the dimensions of the helmet, and in particular the dimensions of the shell and / or adjustments of the internal elements such as headband and internal cap, and on the other hand, the dimensions of the head and especially the user's face. To this end, the helmet of the invention includes means for adjusting the position of the hooking means of the mask.

Ainsi, le casque de protection de l'invention est du type comprenant des moyens d'accrochage pour un masque respiratoire, et est caractérisé en ce qu'il comprend des moyens de réglage en position des moyens d'accrochage, permettant le positionnement de ceux-ci dans au moins deux positions.Thus, the protective helmet of the invention is of the type comprising attachment means for a respiratory mask, and is characterized in that it comprises position adjustment means attachment means, allowing the positioning thereof in at least two positions.

Selon une caractéristique complémentaire, les moyens d'accrochage sont constitués par un cran d'accrochage ou une saillie d'accrochage solidaire du casque, tandis que, selon un mode d'exécution préféré, le cran d'accrochage ou la saillie d'accrochage est solidaire d'une pièce d'accrochage fixée à la coque du casque de façon réglable pour pouvoir en modifier la position.According to an additional characteristic, the means hooking consist of a hooking notch or a projection fixed attachment to the helmet, while, according to an embodiment preferred, the hooking notch or the hooking projection is integral an attachment piece fixed to the helmet shell in an adjustable manner to be able to change the position.

Ajoutons que le casque de protection de l'invention comprend une coque externe comprenant deux parois latérales correspondant aux zones occupées par les oreilles de l'utilisateur sachant que chacune de ces parois latérales comprend une pièce d'accrochage.Add that the protective helmet of the invention includes an outer shell comprising two side walls corresponding to the areas occupied by the user's ears knowing that each of these side walls includes a hanging piece.

Par ailleurs, les moyens de réglage peuvent être continus ou discontinus, pour permettre, soit un réglage fin, soit un réglage pas à pas selon deux, voire plus, et par exemple trois positions successives.Furthermore, the adjustment means can be continuous or discontinuous, to allow either a fine adjustment or a step adjustment in two or more, for example three successive positions.

Selon un mode d'exécution préféré, les moyens de réglage sont constitués par une succession de saillies solidaires de la coque coopérant avec une succession de profils en creux réalisés dans la pièce d'accrochage ou inversement, tandis que des moyens de verrouillage sont prévus pour verrouiller la pièce d'accrochage dans la position choisie, une fois celle-ci déterminée.According to a preferred embodiment, the adjustment means are constituted by a succession of projections integral with the cooperating shell with a succession of hollow profiles made in the room hooking or vice versa, while locking means are designed to lock the attachment piece in the chosen position, once it is determined.

Selon un autre mode d'exécution, l'une au moins des pièces d'accrochage est fixée à la coque du casque par l'intermédiaire d'une pièce intermédiaire et, selon un mode préféré, cette pièce intermédiaire est constituée par un étrier ouvert, qui l'est vers l'avant pour être fixé à l'extérieur de la coque.According to another embodiment, at least one of the parts is attached to the helmet shell by means of a intermediate piece and, according to a preferred embodiment, this intermediate piece consists of an open bracket, which is forward to be fixed to the outside of the hull.

D'autres caractéristiques et avantages de l'invention se dégageront de la description qui va suivre en regard des dessins annexés qui ne sont donnés qu'à titre d'exemples non limitatifs.Other characteristics and advantages of the invention will emerge of the description which will follow with regard to the appended drawings which are not given only by way of nonlimiting examples.

Le casque de protection (1) équipé du dispositif d'accrochage de masque respiratoire selon l'invention peut être de tout type, comme par exemple du type de celui utilisé par les sapeurs pompiers et qui çomprend une coque externe principale (2) protégeant la boíte crânienne et la nuque de l'utilisateur et présentant une ouverture faciale avant (3) dans la zone occupée par la face proprement dite de ce dernier, ledit casque ayant un plan longitudinal vertical (P) de symétrie général.The protective helmet (1) equipped with the attachment device respiratory mask according to the invention can be of any type, such as example of the type used by firefighters and which includes a main external shell (2) protecting the box cranial and the neck of the user and having a facial opening front (3) in the area occupied by the actual face of the latter, said helmet having a vertical longitudinal plane (P) of general symmetry.

La coque est en matériau rigide et peut être en tout matériau approprié tel qu'en matière plastique, en acier, en aluminium ou matériau composite du type comprenant un empilage de couches de fibres de renfort, imprégnées et liées entre elles par une matrice en résine. Ladite coque externe est constituée par une paroi sensiblement sphérique comprenant plusieurs portions de paroi, à savoir, une portion avant supérieure de paroi (4), prolongée vers l'arrière par une portion arrière supérieure de paroi (5), elle-même prolongée vers le bas par une portion arrière inférieure de paroi (6) et comprend, par ailleurs, deux portions latérales de paroi, une portion latérale droite de paroi (7a) et une portion latérale gauche de paroi (7b). La portion avant supérieure (4) correspond à la zone occupée par le front de l'utilisateur et est limitée par la bordure supérieure (8) de l'ouverture faciale (3) qui, quant à elle, est limitée latéralement par deux bordures latérales (9). La portion arrière supérieure de paroi (5) correspond à la zone occupée par la boíte crânienne de l'utilisateur, tandis que la portion arrière inférieure de paroi (6) correspond à la zone occupée par la nuque de l'utilisateur. Ajoutons à cela que la paroi de la coque est limitée vers le bas par une bordure inférieure (10). Les portions latérales de paroi (7a, 7b) correspondent aux zones occupées par les oreilles de l'utilisateur et sont limitées vers l'avant par la bordure latérale correspondante (9) de l'ouverture faciale (3) et vers le bas par les extrémités avant de la bordure inférieure (10).The shell is made of rigid material and can be of any material suitable such as plastic, steel, aluminum or material composite of the type comprising a stack of layers of fiber reinforcement, impregnated and linked together by a resin matrix. said outer shell consists of a substantially spherical wall comprising a plurality of wall portions, namely, a front portion upper wall (4), extended rearwards by a rear portion upper wall (5), itself extended downwards by a portion lower rear wall (6) and further includes two portions side wall, a straight side wall portion (7a) and a portion left side of wall (7b). The upper front portion (4) corresponds to the area occupied by the user's forehead and is limited by the border upper (8) of the facial opening (3) which, in turn, is limited laterally by two lateral edges (9). The upper rear portion wall (5) corresponds to the area occupied by the cranium the user, while the lower rear wall portion (6) corresponds to the area occupied by the user's neck. Let's add to that the hull wall is bounded down by a border lower (10). The lateral wall portions (7a, 7b) correspond to the areas occupied by the user's ears and are limited towards the front by the corresponding lateral border (9) of the facial opening (3) and down through the front ends of the bottom edge (10).

Le casque (1) selon l'invention permet son utilisation en combinaison avec un masque respiratoire amovible (11) du type, par exemple, qui comprend deux bras latéraux de fixation (12a, 12b) dont chacune des extrémités libres (13a, 13b) comprend un crochet d'accrochage (14a, 14b) destiné à venir en prise avec des crans d'accrochage (15a, 15b), formés par des logements en creux, disposés sur les parois latérales (7a, 7b) de la coque (2).The helmet (1) according to the invention allows its use in combination with a removable breathing mask (11) of the type, for example, which comprises two lateral fixing arms (12a, 12b) of which each of the free ends (13a, 13b) includes a hook attachment (14a, 14b) intended to engage with notches attachment (15a, 15b), formed by recessed housings, arranged on the side walls (7a, 7b) of the shell (2).

Ainsi, la coque du casque comprend de part et d'autre sur ses deux parois latérales (7a, 7b) des moyens d'accrochage, tel qu'un cran d'accrochage, constitués par un logement en creux (15a, 15b) réalisé dans une pièce d'accrochage (16a, 16b).Thus, the shell of the helmet comprises on both sides on its two side walls (7a, 7b) for hooking means, such as a notch attachment, constituted by a hollow housing (15a, 15b) produced in a hooking piece (16a, 16b).

Selon une caractéristique de l'invention, chacune des pièces d'accrochage (16a, 16b) est fixée à la paroi latérale correspondante (7a, 7b) du casque de façon à pouvoir en régler la position. Ainsi, des moyens de fixation réglables sont prévus pour fixer les pièces d'accrochage sur la coque. Ces moyens sont des moyens de réglage continus permettant de positionner de façon précise les pièces d'accrochage ou des moyens de réglage discontinus permettant de positionner lesdites pièces d'accrochage dans différentes positions successives, comme deux, voire plus, et, par exemple, trois, comme selon le mode de réalisation représenté.According to a characteristic of the invention, each of the parts attachment (16a, 16b) is fixed to the corresponding side wall (7a, 7b) of the helmet so that the position can be adjusted. So, adjustable fixing means are provided for fixing the parts hooking on the hull. These means are means of adjustment continuous for precise positioning of the parts attachment or discontinuous adjustment means allowing position said attachment pieces in different positions successive, like two or more, and, for example, three, like the embodiment shown.

Les moyens de réglage sont réalisés par tous moyens comme, par exemple, une saillie ou une succession de saillies (17) coopérant avec une succession de creux correspondants (18). Selon le mode d'exécution, les moyens de réglage pour chacune des pièces d'accrochage sont constitués par un ensemble constitué de trois saillies successives centrales (17a, 17b, 17c) et deux pions latéraux (19', 19") réalisés sur la paroi latérale (7a, 7b) de la coque, tandis que la pièce d'accrochage (16a, 16b) comprend une succession de cinq profils centraux en creux (18a, 18b, 18c, 18d, 18e) et deux successions (20a, 20b) de trois logements latéraux (20', 20", 20"').The adjustment means are produced by any means such as, for example example, a projection or a succession of projections (17) cooperating with a succession of corresponding depressions (18). Depending on the mode of execution, the adjustment means for each of the attachment pieces are constituted by an assembly made up of three successive central projections (17a, 17b, 17c) and two lateral pins (19 ', 19 ") produced on the lateral wall (7a, 7b) of the shell, while the attachment part (16a, 16b) comprises a succession of five hollow central profiles (18a, 18b, 18c, 18d, 18th) and two successions (20a, 20b) of three lateral housings (20 ', 20 ", 20"').

Les saillies successives centrales (17) de la coque (2) sont destinées à s'engager dans les profils en creux centraux (18) correspondants de la pièce d'accrochage tandis que les pions latéraux (19', 19") sont engagés dans les logements latéraux correspondants (20a, 20b).The successive central projections (17) of the shell (2) are intended to engage in the central hollow profiles (18) corresponding to the attachment piece while the side pins (19 ', 19 ") are engaged in the corresponding lateral housings (20a, 20b).

Les saillies successives centrales (17a, 17b, 17c, 17d, 17e) sont constituées par des parois successives parallèles ayant la forme générale de triangles, tandis que les pions latéraux (19', 19") sont cylindriques ou coniques. De même, les profils en creux (18a, 18b, 18c, 18d, 18e) ont une forme et des dimensions complémentaires aux saillies. Par ailleurs, les logements latéraux sont cylindriques ou coniques pour correspondre aux pions qui les reçoivent. The successive central projections (17a, 17b, 17c, 17d, 17th) are constituted by successive parallel walls having the general shape triangles, while the side pins (19 ', 19 ") are cylindrical or conical. Similarly, the hollow profiles (18a, 18b, 18c, 18d, 18th) have a shape and dimensions complementary to the projections. In addition, lateral housings are cylindrical or conical to correspond to pawns who receive them.

Ainsi, la pièce d'accrochage (16a, 16b) peut prendre plusieurs positions à savoir, dans l'exemple de réalisation lune des trois positions (A, B, C).Thus, the attachment piece (16a, 16b) can take several positions namely, in the embodiment one of the three positions (A, B, C).

Le dispositif comprend, bien entendu, des moyens de verrouillage permettant le verrouillage de la pièce d'accrochage (16a, 16b) dans la position choisie. A titre d'exemple, les moyens de verrouillage sont tels qu'illustrés, constitués par une pige mobile longitudinale (21) engagée, d'une part, dans un trou (22) réalisé dans les saillies (17) et, d'autre part, dans un trou (23) correspondant réalisé dans l'axe des pièces d'accrochage (16a, 16b).The device includes, of course, locking means allowing the locking of the attachment piece (16a, 16b) in the chosen position. By way of example, the locking means are such as illustrated, constituted by a longitudinal movable rod (21) engaged, on the one hand, in a hole (22) made in the projections (17) and, on the other hand, in a corresponding hole (23) made in the axis of the parts attachment (16a, 16b).

On a illustré aux figures 10a, 10b, 10c, 11a, 11b, 11c les moyens d'accrochage selon trois positions différentes : une position arrière (A) illustrée aux figures 10a et 11a, une position avant (C) illustrée aux figures 10c et 11c, et une position intermédiaire (B) illustrée par les figures 10b et 11b.FIGS. 10a, 10b, 10c, 11a, 11b, 11c have illustrated the means attachment in three different positions: a rear position (A) illustrated in FIGS. 10a and 11a, a front position (C) illustrated in the figures 10c and 11c, and an intermediate position (B) illustrated by FIGS. 10b and 11b.

La position arrière (A) est obtenue par engagement de trois saillies (17a, 17b, 17c) dans les trois profils en creux avant (18c, 18d, 18e) de la pièce d'accrochage.The rear position (A) is obtained by engagement of three projections (17a, 17b, 17c) in the three front hollow profiles (18c, 18d, 18th) of the attachment piece.

La position avant (C) est obtenue par engagement de trois saillies (17a, 17b, 17c) dans les trois profils en creux arrières (18a, 18b, 18c) de la pièce d'accrochage.The front position (C) is obtained by engagement of three projections (17a, 17b, 17c) in the three rear hollow profiles (18a, 18b, 18c) of the attachment piece.

La position intermédiaire (B) est obtenue par engagement de trois saillies (17a, 17b, 17c) dans les trois profils en creux centraux (18b, 18c, 18d) de la pièce d'accrochage.The intermediate position (B) is obtained by engagement of three projections (17a, 17b, 17c) in the three central hollow profiles (18b, 18c, 18d) of the attachment piece.

On aura compris à la lecture de la description que le ou les crans d'accrochage (15a, 15b) constituent les moyens d'accrochage pour le masque respiratoire (11) sur le casque (1). Avantageusement, ces crans d'accrochage (15a, 15b) sont réalisés dans la pièce d'accrochage (16a, 16b) tandis que cette dernière est avantageusement fixée de façon réglable à la coque (2) du casque (1) de façon à pouvoir en modifier la position. La ou lesdites pièces d'accrochage (16a, 16b) selon le mode d'exécution des figures 1 à 11c sont fixées à l'extérieur du casque (1) sur la face externe des parois latérales (7a, 7b) de la coque externe principale (2).It will be understood from reading the description that the notch (s) of attachment (15a, 15b) constitute the attachment means for the respiratory mask (11) on the helmet (1). Advantageously, these notches attachment (15a, 15b) are made in the attachment part (16a, 16b) while the latter is advantageously fixed so adjustable to the shell (2) of the helmet (1) so that it can be changed position. Said attachment part (s) (16a, 16b) according to the mode of execution of FIGS. 1 to 11c are fixed to the outside of the helmet (1) on the outer face of the side walls (7a, 7b) of the main outer shell (2).

Bien entendu, il va de soi que la pièce d'accrochage (16a, 16b) pourrait être fixée à la face interne de la coque de façon à être disposée à l'intérieur du casque et non à l'extérieur, comme cela est le cas du mode de réalisation illustré aux figures 1 à 11c.Of course, it goes without saying that the attachment piece (16a, 16b) could be attached to the inner side of the shell so as to be arranged to inside the helmet and not outside, as is the case with shown in Figures 1 to 11c.

On pourrait aussi prévoir tout type de moyens de verrouillage de la pièce d'accrochage (16a, 16b) autres qu'une pige (21), comme, par exemple, un système vis/écrou ou un système à came monté sur un levier.One could also provide any type of locking means for the attachment piece (16a, 16b) other than a rod (21), such as, for example, a screw / nut system or a cam system mounted on a lever.

Il va de soi aussi que les moyens d'accrochage du masque pourraient être d'un tout autre type comme, par exemple, celui illustré à la figure 13, où les crans d'accrochage (15a, 15b) sont remplacés par des saillies d'accrochage (150a, 150b), tandis que les crochets (14a, 14b) sont remplacés par un trou d'accrochage (140a, 140b)It also goes without saying that the means of attachment of the mask could be of a completely different type like, for example, the one illustrated in Figure 13, where the hooking notches (15a, 15b) are replaced by hooking projections (150a, 150b), while the hooks (14a, 14b) are replaced by a hanging hole (140a, 140b)

On notera que selon les illustrations des figures 3 à 10 les saillies (17) sont solidaires de la coque (2) et notamment de ses parois latérales (7a, 7b), tandis que les profils en creux correspondants (18) sont réalisés dans la pièce d'accrochage (16a, 16b) mais il pourrait en être autrement et notamment l'inverse. Ainsi, les saillies (17) pourraient être sur la pièce d'accrochage (16a, 16b) tandis que les profils en creux seraient sur la coque, comme cela est illustré à la figure 12.Note that according to the illustrations in Figures 3 to 10 the projections (17) are integral with the shell (2) and in particular with its side walls (7a, 7b), while the corresponding hollow profiles (18) are produced in the attachment part (16a, 16b) but it could be otherwise and especially the reverse. Thus, the projections (17) could be on the part attachment (16a, 16b) while the hollow profiles are on the shell, as shown in Figure 12.

Il va de soi que les saillies (17) et les pions (19) pourraient être solidaires d'une pièce intermédiaire (70) telle qu'illustrée à la figure 8a, qui serait alors fixée sur la paroi de la coque. It goes without saying that the projections (17) and the pins (19) could be integral with an intermediate piece (70) as illustrated in FIG. 8a, which would then be fixed on the wall of the hull.

Lors du réglage en position des pièces d'accrochage (16a, 16b) ces dernières sont déplacées selon une trajectoire (XX') inclinée vers le bas (BA) et vers l'avant (AV) pour être sensiblement dans l'alignement des bras latéraux du masque.When adjusting the position of the attachment pieces (16a, 16b) these are moved along a path (XX ') inclined towards the down (BA) and forward (AV) to be noticeably aligned side arms of the mask.

Les figures 14 et 15 sont des vues illustrant une variante d'exécution selon laquelle les pièces d'accrochage (16a, 16b) sont reliées à une pièce intermédiaire (700) fixée au casque. Dans cette réalisation, ladite pièce intermédiaire est constituée par un étrier ouvert vers l'avant formé d'une bande (701) en matériau souple, élastique ou rigide emboítant l'arrière de la coque du casque (1) pour y être fixée par tout moyen. Notons que les extrémités avant de la bande (701) comprennent des moyens destinés à retenir de façon réglable les deux pièces d'accrochage (16a, 16b), ces moyens étant, par exemple, identiques à ceux précédemment décrits (22, 19, 21).Figures 14 and 15 are views illustrating a variant according to which the attachment pieces (16a, 16b) are connected to an intermediate piece (700) fixed to the helmet. In this realization, said intermediate piece is constituted by a stirrup open towards the front formed of a strip (701) of flexible, elastic or rigid material fitting the back of the helmet shell (1) to be fixed by everything way. Note that the front ends of the strip (701) include means intended to adjustably hold the two parts attachment (16a, 16b), these means being, for example, identical to those previously described (22, 19, 21).
