Description

CASQUE DE PROTECTION ET SON DISPOSITIF D' ACCROCHAGE DE MASQUE RESPIRATOIREPROTECTIVE HELMET AND ITS RESPIRATORY MASK ATTACHMENT DEVICE
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 to its attachment device of 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 in various fields, either professionally, as is the case for soldiers, gendarmes or firemen, whether in a civil or private capacity.
On connaît, par exemple, le casque divulgué par le brevet européen EP-B-O 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.It is known, for example, the helmet disclosed by the European patent EP-BO 105 813 which shows a helmet used with a respirator of the type according to which the latter is retained to the helmet shell by two side arms having at their ends hooks intended to engage removably with two hooks made on the side walls of the helmet. This type of layout is particularly practical and is now used by many firefighters. However, despite the telescopic effect of the side arms, intended to give the mask a pressure on the face both safe and comfortable, it happens that in some cases the automatic adaptation is not correct.
On connaît par le brevet européen EP-A-O 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 pouvoir 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. On connaît également du brevet européen EP-B-O 995 465 une solution qui, en prévoyant des moyens de réglage en position des moyens d'accrochage du masque, résoud 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. Cette solution, notamment dans son mode de réalisation des figures 10a à 10c, est très satisfaisante, cependant dans certaines configurations, il serait souhaitable d'améliorer la fixation entre la (es) pièce(s) d'accrochage du masque et le casque.European patent EP-A-0 336 834 discloses a device for retaining a respiratory mask, constituted by attached fastening parts, on each of the side walls of the helmet, so as to adjust its position. However the adjustment in position only allows to change the vertical position, which obviously does not solve the problem previously posed. European patent EP-B-995 465 also discloses a solution which, by providing means for adjusting the fastening means of the mask in position, solves the disadvantage mentioned above by making it possible to adapt the position of the respiratory mask, on the one hand, to the dimensions of the helmet, and in particular to the dimensions of the shell and / or the adjustments of the internal elements such as headband and inner cap, and on the other hand, to the dimensions of the head and in particular the face of the user . This solution, particularly in its embodiment of Figures 10a to 10c, is very satisfactory, however in some configurations, it would be desirable to improve the attachment between the (e) part (s) of attachment of the mask and the helmet.
A cet effet, le casque de l'invention comprend une coque externe et une pièce d'accrochage d'un masque respiratoire fixée à la coque, et des moyens de réglage en position de la pièce d'accrochage, lesdits moyens de réglage comprennent une première succession de saillies solidaires de la coque coopérant avec une première succession de profils en creux réalisés dans la pièce d'accrochage, caractérisé en ce que les moyens de réglage comprennent en outre une succession de saillies complémentaires réalisées chacune sur la paroi séparant deux profils en creux successifs dans la pièce d'accrochage et coopérant avec une succession de profils en creux complémentaires réalisés au moins entre deux profils en saillie solidaires de la coque ou d'une pièce intermédiaire elle-même solidaire de la coque.For this purpose, the helmet of the invention comprises an outer shell and a fastening piece of a respiratory mask attached to the shell, and means for adjusting the position of the attachment piece, said adjustment means comprise a first succession of projections integral with the shell cooperating with a first succession of recessed profiles made in the attachment part, characterized in that the adjustment means further comprises a succession of complementary projections each made on the wall separating two profiles in successive recesses in the attachment piece and cooperating with a succession of complementary recessed profiles made at least between two projecting profiles integral with the shell or an intermediate piece itself integral with the shell.
On augmente ainsi l'ancrage mécanique de la pièce d'accrochage, une fois en position réglée, dans le casque ou la pièce intermédiaire. 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.This increases the mechanical anchoring of the attachment piece, once in the set position, in the helmet or the intermediate piece. Other features and advantages of the invention will become apparent from the description which follows with reference to the accompanying drawings which are given by way of non-limiting examples.

La figure 9 est une vue en coupe montrant comment est réalisée la fixation de la pièce intermédiaire sur le casqueFIG. 9 is a sectional view showing how the attachment of the intermediate piece on the helmet is carried out;
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 comprend une coque externe principale (2) protégeant la boîte 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 générale.The protective helmet (1) equipped with the breathing mask fastening device according to the invention can be of any type, such as for example of the type used by firefighters and which comprises a main outer shell (2) protecting the cranial box and neck of the user and having a facial opening before (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 boîte 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 may be of any suitable material such as plastic, steel, aluminum or composite material of the type comprising a stack of layers of reinforcing fibers, impregnated and bonded together by a resin matrix . Said outer shell is constituted by a substantially spherical wall comprising a plurality of wall portions, namely, an upper front wall portion (4), extended rearwardly by an upper rear wall portion (5), itself extended towards the bottom by a lower rear wall portion (6) and further comprises two wall side portions, a right side wall portion (7a) and a left side wall portion (7b). The upper front portion (4) corresponds to the area occupied by the user's forehead and is limited by the upper edge (8) of the facial opening (3) which, in turn, is limited laterally by two side edges. (9). The upper rear wall portion (5) corresponds to the area occupied by the cranial box of the user, while the lower rear wall portion (6) corresponds to the area occupied by the neck of the user. Add to this that the wall of the shell is limited downward by a lower border (10). The lateral wall portions (7a, 7b) correspond to the areas occupied by the user's ears and are limited forwardly by the corresponding lateral border (9) of the facial opening (3) and downwards by 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 attachment arms (12a, 12b), each of the free ends (13a, 13b). includes a hook hook (14a, 14b) intended to engage with hooking notches (15a, 15b), formed by hollow recesses, 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 of its two side walls (7a, 7b) hooking means, such as a hooking notch, constituted by a hollow recess (15a, 15b) made in a hanging part (16a, 16b).
Selon une caractéristique avantageuse de l'invention, chacune des pièces d'accrochage (16a,16b) est fixée à la paroi latérale correspondante (7a,7b) d'une pièce intermédiaire (16c) elle-même fixée au casque (1) de façon à pouvoir en régler la position.According to an advantageous characteristic of the invention, each of the attachment pieces (16a, 16b) is fixed to the corresponding lateral wall (7a, 7b) of an intermediate piece (16c) which is itself fixed to the helmet (1) of so you can adjust the position.
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). Selon l'invention, les moyens de réglage sont constitués en outre pour chacune des pièces d'accrochage, par un deuxième ensemble complémentaire constitué de six saillies successives complémentaires (18', 18'b, 18'c, 18' d, 18' e, 18'f) chacune réalisée sur la paroi séparant deux profils centraux en creux successifs (18a-18b, 18b-18c, 18c-18d, 18d-18e) avec les deux saillies complémentaires extrêmes (18'a, 18'f) réalisées sur les parois extrêmes de la pièce d'accrochage (16a, 16b).

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 (20) 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). Selon le mode de réalisation illustré, la pièce d'accrochage (16a,16b) comprend deux pattes (160) ménageant entre elles un canal (1600) en bout de pige afin de réaliser un blocage longitudinal de la pige. On a illustré aux figures 7a ,7b, 7c, 8a, 8b, 8c les moyens d'accrochage selon trois positions différentes : une position arrière (A) illustrée aux figures 7a et 8a, une position avant (C) illustrée aux figures 7c et 8c, et une position intermédiaire (B) illustrée par les figures 7b et 7c.The device comprises, of course, locking means for locking the attachment piece (16a, 16b) in the chosen position. By way of example, the locking means are as illustrated, constituted by a longitudinal movable pin (20) engaged, on the one hand, in a hole (22) formed in the projections (17) and, on the other hand, part, in a corresponding hole (23) made in the axis of the attachment parts (16a, 16b). According to the illustrated embodiment, the attachment piece (16a, 16b) comprises two tabs (160) forming between them a channel (1600) at the end of the pin to achieve a longitudinal locking of the pin. FIGS. 7a, 7b, 7c, 8a, 8b, 8c illustrate the hooking means according to three different positions: a rear position (A) illustrated in FIGS. 7a and 8a, a front position (C) illustrated in FIGS. 8c, and an intermediate position (B) illustrated by FIGS. 7b and 7c.
La position arrière (A) est obtenue par engagement de trois sailliesThe rear position (A) is obtained by engaging three protrusions
(17a, 17b, 17c) dans les trois profils en creux avant (18c, 18d, 18e) de la pièce d'accrochage. Les profils en creux complémentaires (17'g,17'h) restant libres.(17a, 17b, 17c) in the three front hollow profiles (18c, 18d, 18e) of the attachment piece. The complementary hollow profiles (17'g, 17'h) remaining free.
Dans la position intermédiaire (B), le premier (17' a) et le dernier (17'h) profils complémentaires en creux restent libres.In the intermediate position (B), the first (17 'a) and the last (17'h) recessed complementary profiles remain free.
Dans la position (C), les deux premiers profils (17'a,17'b) complémentaires restent libres.In the position (C), the first two complementary profiles (17'a, 17'b) remain free.
La figure 9 est une vue en coupe montrant comment est réalisée la fixation de la pièce intermédiaire sur le casque. Ainsi la face inférieure (170) de la pièce intermédiaire (16c) comprend une saillie arrière (171) constituée par une paroi longitudinale inclinée vers le bas et vers l'avant destinée à être engagée dans un trou correspondant (172) réalisé dans la paroi latérale de la coque du casque. Par ailleurs, il est aussi prévu une autre saillie (173) par exemple cylindrique coopérant avec un trou correspondant (174) réalisé dans la paroi latérale du casque, tandis qu'il est prévu une vis de blocage (175) coopérant avec un filetage correspondant réalisé dans la saille (173), ledit filetage étant avantageusement réalisé par un insert métallique. Figure 9 is a sectional view showing how is made the attachment of the intermediate part on the helmet. Thus the lower face (170) of the intermediate piece (16c) comprises a rear projection (171) constituted by a longitudinal wall inclined downwards and forwards intended to be engaged in a corresponding hole (172) formed in the wall side of the helmet shell. Furthermore, there is also provided another projection (173) for example cylindrical cooperating with a corresponding hole (174) formed in the side wall of the helmet, while there is provided a locking screw (175) cooperating with a corresponding thread made in the groove (173), said thread being advantageously made by a metal insert.
