Description

La présente invention est relative aux équipements de protection de tête à masque respiratoire et écran optique.The present invention relates to head protection equipment with a breathing mask and an optical screen.

Plus particulièrement, l'invention concerne un équipement de protection de tête comprenant :

  • un masque respiratoire raccordable à une source de gaz respiratoire et adapté pour être appliqué, dans une position d'utilisation, sur le bas du visage d'un utilisateur, autour de son nez et de sa bouche, et l'alimenter en gaz respiratoire,
  • un écran de protection des yeux adapté pour être appliqué sur le haut du visage de l'utilisateur, autour de ses yeux, et
  • des premier et deuxième éléments de verrou, respectivement situés sur le masque et sur l'écran et adaptés pour coopérer l'un avec l'autre pour assujettir l'écran au masque, lorsque le masque est dans sa position d'utilisation sur le visage de l'utilisateur.
More particularly, the invention relates to head protection equipment comprising:
  • a respirator mask connectable to a respiratory gas source and adapted to be applied, in a position of use, to the lower face of a user, around his nose and mouth, and supply it with respiratory gas,
  • an eye shield adapted to be applied to the user's upper face, around his eyes, and
  • first and second latch members, respectively located on the mask and on the screen and adapted to cooperate with each other to secure the screen to the mask, when the mask is in its use position on the face of the user.

L'invention trouve une application particulièrement importante, bien non exclusive, en aéronautique. Le masque permet alors de lutter contre l'hypoxie ou l'inhalation de gaz toxiques. La réglementation peut également exiger que les pilotes et co-pilotes d'avions de transport portent un équipement de protection contre l'hypoxie, en permanence dans certaines conditions de vol, et notamment à très haute altitude ou lorsqu'un seul pilote est présent dans la cabine.The invention finds a particularly important application, although not exclusive, in aeronautics. The mask then makes it possible to fight against hypoxia or the inhalation of toxic gases. The regulations may also require pilots and co-pilots of transport aircraft to wear hypoxia protection equipment, permanently under certain flight conditions, including at very high altitude or when only one pilot is present in the aircraft. the cabin.

Le document US 5 630 412 décrit un exemple d'un tel équipement de protection qui donne entière satisfaction. Mais il pourrait être intéressant de disposer d'un tel équipement pour lequel la mise en place de l'écran sur le masque, en particulier lorsque le masque est déjà en place sur le visage de l'utilisateur, s'effectue encore plus simplement et plus naturellement.The document US 5,630,412 describes an example of such protective equipment that gives complete satisfaction. But it might be interesting to have such a equipment for which the establishment of the screen on the mask, especially when the mask is already in place on the face of the user, is even more simple and more natural.

La présente invention a notamment pour but de parvenir à ces objectifs.The present invention is intended in particular to achieve these objectives.

A cet effet, on prévoit selon l'invention, un équipement de protection qui, outre les caractéristiques déjà mentionnées, est caractérisé par le fait que les premier et deuxième éléments de verrou sont adaptés pour s'engager et se verrouiller l'un avec l'autre lors d'un mouvement d'approche de l'écran vers le masque comportant une composante dirigée de haut en bas, en référence avec le haut et le bas du visage.For this purpose, according to the invention, protective equipment is provided which, in addition to the features already mentioned, is characterized in that the first and second lock members are adapted to engage and lock one with the another during a movement of approach of the screen towards the mask comprising a component directed from top to bottom, with reference to the top and the bottom of the face.

Grâce à ces dispositions, l'utilisateur, qui porte déjà le masque (par exemple à très haute altitude) et qui doit mettre l'écran (par exemple pour se protéger de fumées et/ou de gaz toxiques ou irritants au contact des yeux), peut d'un geste simple et naturel amener l'écran devant ses yeux et le presser vers le bas sur le masque pour l'assujettir à ce dernier. Le fait que la fixation de l'écran sur le masque se fasse de façon simple et naturelle est particulièrement important en situation d'urgence telles que celles qui nécessitent généralement le port de l'écran.Thanks to these provisions, the user, who already wears the mask (for example at very high altitude) and who must put the screen (for example to protect themselves from smoke and / or toxic or irritating gases in contact with the eyes) , can with a simple and natural gesture bring the screen in front of his eyes and press it down on the mask to subjugate it. The fact that the fixing of the screen on the mask is done in a simple and natural way is particularly important in emergency situations such as those that usually require the port of the screen.

Sur les différentes figures, les mêmes références désignent des éléments identiques ou similaires.In the different figures, the same references designate identical or similar elements.

Un premier mode de réalisation de l'équipement de protection selon l'invention est décrit en relation avec les figures 1 à 6.A first embodiment of the protective equipment according to the invention is described in relation to the Figures 1 to 6 .

Comme représenté sur la figure 1, cet équipement de protection 1 comporte un masque 2, un harnais 4 et un écran 6.As shown on the figure 1 , this protective equipment 1 comprises a mask 2, a harness 4 and a screen 6.

Le masque 2 et le harnais 4 sont d'un type connu. Ils sont par exemple du type de ceux déjà décrits par les documents EP-A-0288391 ou US 5 630 412 .The mask 2 and the harness 4 are of a known type. For example, they are of the type already described in the documents EP-A-0288391 or US 5,630,412 .

Le masque 2 comporte un couvre face oro-nasal 8, un régulateur à la demande 10, un bloc de connexion 12 et une coquille 14. Le régulateur à la demande 10 est raccordé à une source de gaz respiratoire sous pression par un tube souple 16. Le bloc de connexion 12 relie le régulateur à la demande 10 au harnais 4 gonflable. La coquille 14 recouvre l'avant du couvre face oro-nasal 8.The mask 2 comprises an oronasal face cover 8, an on-demand regulator 10, a connection block 12 and a shell 14. The demand regulator 10 is connected to a source of pressurized respiratory gas by a flexible tube 16 The connection block 12 connects the demand regulator 10 to the inflatable harness 4. The shell 14 covers the front of the oro-nasal face cover 8.

Comme représenté sur la figure 2, le couvre face oro-nasal 8 est adapté pour être appliqué sur le bas du visage d'un utilisateur. Le couvre face oro-nasal 8 comporte une cavité recouvrant le nez et la bouche de cet utilisateur. Cette cavité est tapissée d'une membrane souple s'étendant également tout autour de celle-ci, pour former un joint d'étanchéité 18 destiné à être appliqué au contact du visage de l'utilisateur.As shown on the figure 2 , the oronasal face cover 8 is adapted to be applied to the lower face of a user. The oronasal face cover 8 has a cavity covering the nose and mouth of this user. This cavity is lined with a flexible membrane also extending all around thereof, to form a seal 18 intended to be applied in contact with the face of the user.

La coquille 14 comporte une surface d'arête 20 située sensiblement en coïncidence avec celle du nez de l'utilisateur, lorsque celui-ci porte le masque 2. La coquille 14 comporte également 2 surfaces de guidage 22 qui s'étendent, à partir de la surface d'arête 20, vers le bas, en divergeant par rapport à un plan P médian correspond au plan de symétrie de la tête de l'utilisateur.The shell 14 has an edge surface 20 located substantially in coincidence with that of the nose of the user, when the latter is wearing the mask 2. The shell 14 also has 2 guide surfaces 22 which extend, from the edge surface 20, downwards, diverging with respect to a plane P median is the plane of symmetry of the user's head.

Au niveau de la surface d'arête 20, le couvre face oro-nasal 8 comporte une cavité 24 sensiblement conique et une soupape 26. La soupape 26 se trouve vers le haut de la surface d'arête 20. La cavité 24 est située entre la soupape 26 et le bas de la surface d'arête 20, à proximité du bloc de connexion 12.At the ridge surface 20, the nasal-nasal cover 8 has a substantially conical cavity 24 and a valve 26. The valve 26 is located upwardly from the ridge surface 20. The cavity 24 is located between the valve 26 and the bottom of the edge surface 20, near the connection block 12.

La cavité 24 a une forme sensiblement conique qui va en se rétrécissant de la surface d'arête 20 vers l'intérieur du couvre face oro-nasal 8.The cavity 24 has a substantially conical shape which narrows from the ridge surface 20 towards the inside of the oro-nasal face cover 8.

Comme représenté sur la figure 3, au fond de la cavité 24, la surface conique se poursuit par une surface interne cylindrique 28 qui débouche elle-même sur une ouverture évasée 30 dont la surface interne forme une première rampe 32. Cette première rampe 32 est circulaire et continue autour d'une direction Z-.As shown on the figure 3 at the bottom of the cavity 24, the conical surface continues with a cylindrical internal surface 28 which opens itself onto a flared opening 30 whose inner surface forms a first ramp 32. This first ramp 32 is circular and continuous around a direction Z-.

Lorsque l'équipement 1 est sur la tête d'un utilisateur et que celui-ci a la tête droite, la direction Z- s'étend dans le plan P et sa projection sur un axe Z vertical comporte une composante vers le bas non nulle. La rampe 32 forme un premier élément de verrou destiné à coopérer avec un deuxième élément de verrou situé sur l'écran 6.When the equipment 1 is on the head of a user and the head has a straight head, the direction Z- extends in the plane P and its projection on a vertical axis Z has a non-zero component downwards. . The ramp 32 forms a first latch element intended to cooperate with a second latch element located on the screen 6.

Revenant aux figures 1 et 2, le harnais 4 comporte deux sangles 34 constituées chacune d'un tube en matériau élastique entouré d'une gaine inextensible. Les deux sangles 34 ont, lorsque le tube est gonflé, une longueur qui permet de passer autour de têtes de toutes les tailles. Elles sont reliées au bloc de connexion 12. Après mise en place du masque 2 et du harnais 4 sur la tête d'un utilisateur, les tubes des sangles 34 sont dégonflés de manière que l'élasticité des tubes serre le harnais 4 sur la tête de cet utilisateur.Returning to figures 1 and 2 the harness 4 comprises two straps 34 each consisting of a tube of elastic material surrounded by an inextensible sheath. The two straps 34 have, when the tube is inflated, a length that can pass around heads of all sizes. They are connected to the connection block 12. After setting up the 2 mask and the harness 4 on the head of a user, the tubes of the straps 34 are deflated so that the elasticity of the tubes tightens the harness 4 on the head of this user.

L'écran 6 comporte une fenêtre 36 rigide de qualité optique entourée d'un cadre 38 de matière plastique relativement rigide. Le cadre 38 est muni d'un joint d'étanchéité 40 adapté pour appliquer une surface relativement importante au contact du visage de l'utilisateur.The screen 6 comprises a rigid window 36 of optical quality surrounded by a frame 38 of relatively rigid plastic material. The frame 38 is provided with a seal 40 adapted to apply a relatively large surface in contact with the face of the user.

L'écran 6 et le masque 2 sont avantageusement prévus de façon à organiser une circulation de gaz respiratoire dans l'écran 6 lorsque ce dernier est en place sur le visage de l'utilisateur. En particulier, lors de la mise en place de l'écran 6 sur le masque 2, la soupape 26, fermée lorsque l'écran 6 n'est pas en place, s'ouvre pour admettre du gaz respiratoire depuis l'intérieur du masque 2 vers l'intérieur de l'écran 6. Le gaz respiratoire peut s'échapper par fuite entre le joint d'étanchéité 40 et la peau. Des fentes peuvent également être prévues dans la partie supérieure du joint d'étanchéité 40 de façon à guider le gaz respiratoire balayant le volume situé entre le visage et l'écran 6.The screen 6 and the mask 2 are advantageously provided so as to organize a flow of breathing gas in the screen 6 when the latter is in place on the face of the user. In particular, when setting up the screen 6 on the mask 2, the valve 26, closed when the screen 6 is not in place, opens to admit respiratory gas from inside the mask 2 towards the inside of the screen 6. The breathing gas can escape by leakage between the seal 40 and the skin. Slots may also be provided in the upper part of the seal 40 so as to guide the breathing gas sweeping the volume between the face and the screen 6.

L'ouverture de la soupape 26 lors de la mise en place de l'écran 6 sur le masque 2 est réalisée par l'insertion d'une languette 42 (voir figures 1 et 4) sous un rebord 44 surplombant la soupape 26 (voir figures 1 et 2). Lorsque la languette 42 est insérée sous le rebord 44, elle presse un piston 46, ouvrant ainsi un canal d'admission de gaz respiratoire mettant en communication le bloc de connexion 12 au volume situé entre l'écran 6 et le visage de l'utilisateur. Lorsque l'écran 6 est désolidarisé du masque 2, un ressort non représenté repousse le piston 46 vers un siège également non représenté, afin de fermer le canal d'admission. Avantageusement, le canal d'admission débouche au niveau du piston 46 de manière à ce que le gaz respiratoire s'échappe, dans l'écran 6, directement par la soupape 26. D'autres moyens de gestion de l'admission du gaz respiratoire dans l'écran 6 sont également envisageables.The opening of the valve 26 during the placement of the screen 6 on the mask 2 is achieved by the insertion of a tongue 42 (see figures 1 and 4 ) under a rim 44 overhanging the valve 26 (see figures 1 and 2 ). When the tongue 42 is inserted under the flange 44, it presses a piston 46, thus opening a breathing gas intake channel placing the connection block 12 in communication with the volume located between the screen 6 and the user's face. . When the screen 6 is detached from the mask 2, a not shown spring pushes the piston 46 to a seat also not shown, in order to close the channel intake. Advantageously, the inlet channel opens at the piston 46 so that the breathing gas escapes, in the screen 6, directly through the valve 26. Other means for managing the admission of the breathing gas in the screen 6 are also possible.

Comme représenté sur la figure 4, l'écran 6 comporte un bloc de fixation-préhension 50 prévu pour autoriser une mise en place rapide et facile de l'écran 6 sur la coquille 14 du masque 2. Les moyens de verrouillage de l'écran 6 sur le masque 2 peuvent avoir des constitutions très diverses et le mode de réalisation donné ci-dessous n'en est qu'un exemple.As shown on the figure 4 , the screen 6 comprises a gripping block 50 designed to allow a quick and easy installation of the screen 6 on the shell 14 of the mask 2. The locking means of the screen 6 on the mask 2 can have very different constitutions and the embodiment given below is just one example.

Dans ce mode de réalisation, le bloc de fixation-préhension 50 appartenant à l'écran 6 comporte une forme sensiblement en V inversé lorsqu'on le considère en coupe dans un plan perpendiculaire au plan P de symétrie du visage, lorsque l'écran 6 et le masque 2 sont en place sur la tête de l'utilisateur.In this embodiment, the gripping-grip block 50 belonging to the screen 6 has a shape substantially inverted V when considered in section in a plane perpendicular to the plane P of symmetry of the face, when the screen 6 and the mask 2 are in place on the user's head.

Cette forme en V comporte deux ailes 52 sensiblement symétriques par rapport au plan P médian de symétrie du visage, lorsque l'équipement 1 est porté par l'utilisateur. Ces ailes 52 se rejoignent au niveau d'une zone centrale 54 à partir de laquelle s'étend un téton 56. Le téton 56 constitue le deuxième élément de verrou qui coopère avec la rampe 32 pour assujettir l'écran 6 au masque 2.This V shape comprises two wings 52 substantially symmetrical with respect to the median P plane of symmetry of the face, when the equipment 1 is worn by the user. These wings 52 meet at a central zone 54 from which extends a pin 56. The pin 56 constitutes the second latch member which cooperates with the ramp 32 to secure the screen 6 to the mask 2.

Les ailes 52 s'étendent entre une extrémité haute 58 proche du téton 56 et une extrémité basse 60 éloignée du téton 56. Ces ailes 52 s'écartent du plan P de symétrie du visage en direction de leur extrémité basse 60. Ces ailes 52 permettent un guidage, par les surfaces de guidage 22 du masque 2, facilitant le positionnement de l'écran 6 sur le masque 2.The wings 52 extend between an upper end 58 near the stud 56 and a lower end 60 remote from the stud 56. These wings 52 deviate from the plane P of symmetry of the face towards their lower end 60. These wings 52 allow a guide, by the guide surfaces 22 of the mask 2, facilitating the positioning of the screen 6 on the mask 2.

Comme représenté sur la figure 3, le téton 56 se compose d'une tige interne 62 et d'une tige externe 64.As shown on the figure 3 , the nipple 56 is consists of an inner rod 62 and an outer rod 64.

La tige interne 62 est par exemple en métal et la tige externe 64 est par exemple en matière plastique.The inner rod 62 is for example of metal and the outer rod 64 is for example plastic.

La tige externe 64 forme un manchon autour de la tige interne 62. Ce manchon présente sur sensiblement la moitié de sa longueur des découpes de manière à ce que la moitié de la tige externe 64 située du côté de son extrémité libre forme des languettes élastiques 69.The outer rod 64 forms a sleeve around the inner rod 62. This sleeve has on substantially half of its length of the cutouts so that the half of the outer rod 64 located on the side of its free end forms elastic tongues 69 .

Les tiges interne 62 et externe 64 s'étendent entre une extrémité libre comportant un renflement 66, 68 et une surface de pression 70, 72 par l'intermédiaire desquelles est transmise au téton 56, une force F pour déplacer le téton 56 longitudinalement sensiblement dans la première direction Z-, entre une position de verrouillage (partie droite de la figure 3) et une position de déverrouillage (partie gauche de la figure 3), au sein du bloc de fixation-préhension 50.The internal 62 and outer 64 rods extend between a free end having a bulge 66, 68 and a pressure surface 70, 72 through which is transmitted to the pin 56, a force F to move the pin 56 longitudinally substantially in the first direction Z-, between a locking position (right side of the figure 3 ) and an unlock position (left side of the figure 3 ), within the gripping block 50.

Des premier 74 et deuxième 76 ressorts sont intercalés respectivement d'une part entre la tige interne 62 et la tige externe 64 et d'autre part entre la tige externe 64 et le bloc de fixation-préhension 50. Ces ressorts 74,76 rappellent le téton 56 vers l'intérieur du bloc de fixation-préhension 50.First 74 and second 76 springs are interposed respectively on the one hand between the inner rod 62 and the outer rod 64 and on the other hand between the outer rod 64 and the gripping block-grip 50. These springs 74,76 recall the pin 56 to the inside of the gripping block 50.

Le bloc de fixation-préhension 50 présente, symétriquement par rapport au plan P médian de symétrie du visage, des surfaces de préhension 82 qui se prolongent vers le haut de part et d'autre d'un bouton-poussoir 84 solidaire de la surface de pression 70 de la tige interne 62 (voir figures 1, 2 et 4).The fixation-gripping block 50 presents, symmetrically with respect to the median plane of symmetry of the face, gripping surfaces 82 which extend upwards on either side of a push-button 84 secured to the surface of the pressure 70 of the inner rod 62 (see figures 1 , 2 and 4 ).

En position relâchée (correspondant sensiblement à la position verrouillée), mais lorsque l'écran 6 n'est pas solidaire du masque 2, la tige externe 64 est bloquée contre l'action du deuxième ressort 76 au niveau d'une butée 78 et la tige intérieure 62 est bloquée, contre l'action du premier ressort 74, sur une rampe 80 ménagée sur la surface interne de la tige externe 64.In the relaxed position (substantially corresponding to the locked position), but when the screen 6 is not secured to the mask 2, the outer rod 64 is locked against the action of the second spring 76 at a stop 78 and the inner rod 62 is locked, against the action of the first spring 74, on a ramp 80 formed on the inner surface of the outer rod 64.

Pour mettre en place l'écran 6 sur le masque 2, l'utilisateur saisit l'écran 6 par le bloc de fixation-préhension 50, puis, dans le mode de réalisation décrit, presse le bouton poussoir 84, à l'aide d'un ou deux doigts, alors qu'il saisit entre le pouce et un ou plusieurs autres doigts les surfaces d'appui 82. En pressant sur le bouton pressoir 84, l'utilisateur fait sortir le téton 56 du bloc de fixation-préhension 50. Plus précisément, la tige interne 62 est déplacée longitudinalement parallèlement à la direction Z- jusqu'à dégager le renflement 66 de la tige externe 64. Ainsi, lorsque l'écran 6 est approché du masque 2, les ailes 52 sont guidées par les surfaces de guidage 22. Puis, lorsque l'écran 6 se trouve à proximité du masque 2, le positionnement plus précis de l'écran 6 sur le masque 2 est guidé par l'entrée du téton 56 dans la cavité 24. Le renflement 66 étant dégagé de la tige externe 64, les languettes 69 de cette tige externe 64 peuvent être déformées radialement vers la tige interne 62 jusqu'à ce que le renflement 68 de la tige externe 64 se trouve au niveau de l'ouverture évasée 30. Les languettes 69 de la tige externe 64 peuvent alors s'écarter radialement vers l'extérieur.To set up the screen 6 on the mask 2, the user enters the screen 6 by the gripping block 50, then, in the embodiment described, presses the push button 84, using one or two fingers, while grasping between the thumb and one or more other fingers the bearing surfaces 82. By pressing the press button 84, the user releases the pin 56 of the gripping-grip block 50 More specifically, the inner rod 62 is moved longitudinally parallel to the Z- direction until disengaging the bulge 66 from the outer rod 64. Thus, when the screen 6 is approaching the mask 2, the wings 52 are guided by the Guiding surfaces 22. Then, when the screen 6 is close to the mask 2, the more precise positioning of the screen 6 on the mask 2 is guided by the entry of the pin 56 into the cavity 24. The bulge 66 being disengaged from the outer rod 64, the tongues 69 of this external rod 64 can be e is deformed radially towards the inner rod 62 until the bulge 68 of the outer rod 64 is at the flared opening 30. The tongues 69 of the outer rod 64 can then move radially outwardly. .

Le calibrage des premier 74 et deuxième 76 ressorts est déterminé pour que le renflement 66 de la tige interne retourne dans la tige externe 64 avant que le renflement 68 de la tige externe 64 ne revienne au niveau de l'ouverture évasée 30, lorsque l'utilisateur relâche le bouton pressoir 84, le renflement 68 de la tige 64 est alors bloqué dans l'ouverture évasée 30. Ainsi, les languettes 69 de la tige externe 64 se trouvent retenues radialement vers l'extérieur. L'action des premier 74 et deuxième 76 ressorts contribue à maintenir l'écran 6 plaqué contre le masque 2.Calibration of the first 74 and second 76 springs is determined so that the bulge 66 of the inner rod returns to the outer rod 64 before the bulge 68 of the outer rod 64 returns to the level of the flared opening 30 when the user releases the press button 84, the bulge 68 of the rod 64 is then blocked in the flared opening 30. Thus, the tabs 69 of the outer rod 64 are retained radially towards outside. The action of the first 74 and second 76 springs helps keep the screen 6 pressed against the mask 2.

Pour désolidariser l'écran 6 du masque 2, l'utilisateur saisit l'écran 6 au niveau des surfaces d'appui 82 et applique une pression sur le bouton-poussoir 84. Les renflements 66, 68 sont alors dégagés de l'ouverture évasée 30. En tirant sur l'écran 6, tout en maintenant le bouton-poussoir 84 pressé, l'utilisateur dégage le téton 56 de la cavité 24. Plus précisément, les languettes 69 de la tige externe de 64 se déforment radialement vers l'intérieur lors du passage du renflement 68 au niveau de l'ouverture évasée 30 et de la surface interne cylindrique 28, ce qui est rendu possible par le fait que le renflement 66 de la tige interne 62 ne se trouve plus à l'intérieur de la tige externe 64.To separate the screen 6 of the mask 2, the user grasps the screen 6 at the bearing surfaces 82 and applies a pressure on the push button 84. The bulges 66, 68 are then released from the flared opening 30. By pulling on the screen 6, while maintaining the push-button 84 pressed, the user releases the pin 56 from the cavity 24. More specifically, the tongues 69 of the outer rod of 64 deform radially towards the inside when the bulge 68 passes through the flared opening 30 and the cylindrical inner surface 28, which is made possible by the fact that the bulge 66 of the inner rod 62 is no longer inside the outer rod 64.

Le masque 2 et l'écran 6 de l'équipement 1 selon l'invention peuvent être stockés indépendamment l'un de l'autre. Le masque 2 peut être disposé, lorsqu'il n'est pas utilisé sur un support ou dans une boîte classique. L'écran 6, lorsqu'il n'est pas utilisé, peut être stocké dans une boîte 90 d'écran ou simplement accroché. La figure 5 représente un mode de réalisation d'une telle boîte d'écran 90. Il s'agit, par exemple d'une boîte de caoutchouc avec une face avant 92 présentant une découpe 94 qui permet d'introduire l'écran 6 dans la boîte 90 ou de l'en extraire. Lorsque l'écran 6 est dans la boîte 90, le bloc de fixation-préhension 50 fait au moins en partie saillie au niveau de la découpe 94, afin de faciliter la préhension de l'écran 6 et son extraction de la boîte 90. La boîte 90 est fixée, par sa face arrière 91, par exemple à une paroi intérieure d'aéronef.The mask 2 and the screen 6 of the equipment 1 according to the invention can be stored independently of one another. The mask 2 can be arranged when it is not used on a support or in a conventional box. The screen 6, when not in use, can be stored in a screen box 90 or simply hooked. The figure 5 represents an embodiment of such a screen box 90. This is, for example a rubber box with a front face 92 having a cutout 94 which allows to introduce the screen 6 in the box 90 or extract it. When the screen 6 is in the box 90, the fixing-gripping block 50 is at least partly projecting at the cutout 94, in order to facilitate the gripping of the screen 6 and its extraction from the box 90. box 90 is fixed by its rear face 91, for example to an aircraft interior wall.

Selon une variante, l'écran 6 est disposé, lorsqu'il n'est pas utilisé, sur un présentoir 100. A titre illustratif, un exemple d'un tel présentoir 100 est représenté sur la figure 6. Ce présentoir 100 comporte un porte-écran 102 présentant une forme sensiblement analogue à celle de la coquille 14. Ce porte-écran 102 comporte une cavité 106 identique à la cavité 24 du masque 2. Ainsi, si l'utilisateur enlève l'écran 6 du masque 2 pour le poser sur le présentoir 100, il acquiert par ce geste la mémoire du lieu où l'écran 6 a été stocké et du geste qu'il aura à faire pour positionner l'écran 6 sur le masque 2. En cas d'urgence, il reprendra l'écran 6 pour le positionner sur le masque 2 avec un geste qu'il connaît.According to a variant, the screen 6 is arranged, when not in use, on a display stand 100. illustrative, an example of such a display 100 is shown on the figure 6 . This display unit 100 comprises a screen holder 102 having a shape substantially similar to that of the shell 14. This screen holder 102 has a cavity 106 identical to the cavity 24 of the mask 2. Thus, if the user removes the screen 6 of the mask 2 to put it on the display 100, it acquires by this gesture the memory of the place where the screen 6 has been stored and the gesture it will have to make to position the screen 6 on the mask 2. In case emergency, it will resume the screen 6 to position it on the mask 2 with a gesture he knows.

Avantageusement, pour des raisons analogues, le présentoir 100 comporte un porte-masque 108. Sur le présentoir 100, l'écran 6 et le masque 2 sont stockés indépendamment l'un de l'autre. Si l'utilisateur prend le masque 2 sur le porte-masque 108 pour le mettre, il mémorise en même temps le lieu où se trouve l'écran 6. Ainsi en cas d'urgence, l'utilisateur pourra retrouver l'écran 6 à un endroit qu'il connaît déjà.Advantageously, for similar reasons, the display 100 includes a mask holder 108. On the display 100, the screen 6 and the mask 2 are stored independently of one another. If the user takes the mask 2 on the mask holder 108 to put it, it stores at the same time the location where the screen 6 is located. Thus in case of emergency, the user can find the screen 6 to a place he already knows.

L'équipement selon l'invention peut faire l'objet de nombreuses variantes.The equipment according to the invention can be the subject of numerous variants.

Par exemple, selon l'une de ces variantes, l'équipement selon l'invention comporte un dispositif de verrouillage adapté pour qu'un utilisateur n'ait qu'à presser l'écran 6 sur le masque 2 pour qu'ils se verrouillent l'un sur l'autre, et qu'à exercer une traction au niveau d'éléments de préhension pour déverrouiller ce dispositif de verrouillage et ôter l'écran 6 du masque 2, selon des gestes correspondant sensiblement à ceux de la pose et du retrait de lunettes sur un nez.For example, according to one of these variants, the equipment according to the invention comprises a locking device adapted for a user to press the screen 6 on the mask 2 so that they lock themselves one on the other, and that to exert traction at the gripping elements to unlock the locking device and remove the screen 6 of the mask 2, in gestures corresponding substantially to those of the installation and the removal of glasses on a nose.

Un exemple d'une telle disposition est illustré par le deuxième mode de réalisation de l'équipement selon l'invention décrit ci-dessous en référence aux figures 7 à 15.An example of such an arrangement is illustrated by the second embodiment of the equipment according to the invention described below with reference to Figures 7 to 15 .

Comme représenté sur la figure 7, cet équipement de protection 201 comporte un masque 202, un harnais 204 et un écran 206.As shown on the figure 7 , this protective equipment 201 comprises a mask 202, a harness 204 and a screen 206.

Le masque 202 et le harnais 204 sont d'un type connu. Ils sont par exemple du type de ceux déjà décrits dans les documents EP-A-0 288 391 ou US 5 630 412 .The mask 202 and the harness 204 are of a known type. They are for example of the type already described in the documents EP-A-0 288 391 or US 5,630,412 .

Le masque 202 comporte un couvre face oronasal 208, un régulateur à la demande 210, un bloc de connexion 212 et une coquille 214. Le régulateur à la demande 210 est raccordé à une source de gaz respiratoire sous pression par un tube souple 216. Le bloc de connexion 212 relie le régulateur à la demande 210 au harnais 204 gonflable. La coquille 214 recouvre l'avant du couvre face oronasal 208.The mask 202 includes an oronasal face shield 208, an on demand regulator 210, a connection block 212, and a shell 214. The demand regulator 210 is connected to a source of pressurized respiratory gas by a flexible tube 216. The Connection block 212 connects the demand regulator 210 to the inflatable harness 204. The shell 214 covers the front of the oronasal face cover 208.

Le couvre face oronasal 208 est adapté pour être appliqué sur le bas du visage d'un utilisateur. Comme représenté sur la figure 8, le couvre face oronasal 208 comporte une cavité destinée à recouvrir le nez et la bouche de cet utilisateur. Cette cavité est tapissée d'une membrane souple s'étendant également tout autour de celle-ci, pour former un joint d'étanchéité 218 destiné à être appliqué au contact du visage de l'utilisateur.The oronasal face cover 208 is adapted to be applied to the lower face of a user. As shown on the figure 8 , the oronasal face cover 208 has a cavity intended to cover the nose and the mouth of this user. This cavity is lined with a flexible membrane also extending all around thereof, to form a seal 218 intended to be applied in contact with the face of the user.

La coquille 214 comporte une surface d'arête 220 située sensiblement en coïncidence avec celle du nez de l'utilisateur, lorsque celui-ci porte le masque 202.The shell 214 has a ridge surface 220 located substantially in coincidence with that of the nose of the user, when the latter is wearing the mask 202.

Au niveau de la surface d'arête 220, le couvre face oronasal 208 comporte une soupape 226. La soupape 226 se trouve vers le haut de la surface d'arête 220.At the ridge surface 220, the oronasal face cover 208 includes a valve 226. The valve 226 is upwardly at the ridge surface 220.

La coquille 214 comporte une rampe de verrouillage 224. La rampe de verrouillage 224 est située au bas de la surface d'arête 220, entre la soupape 226 et le bloc de connexion 212.The shell 214 has a locking ramp 224. The locking ramp 224 is located at the bottom of the edge surface 220, between the valve 226 and the connection block 212.

Lorsque l'équipement 201 est sur la tête d'un utilisateur et que celui-ci a la tête droite, on peut définir un plan P qui correspond au plan de la feuille sur laquelle se trouve la figure 8. Ce plan P correspond au plan de symétrie de la tête de l'utilisateur. Il passe par le sommet de la surface d'arête 220. On définit également une direction Z verticale, qui s'étend de bas en haut en référence au haut et au bas du visage d'un utilisateur.When the equipment 201 is on the head of a user and that it has the head right, we can define a plane P which corresponds to the plane of the sheet on which is the figure 8 . This plane P corresponds to the plane of symmetry of the head of the user. It passes through the top of the edge surface 220. A vertical Z direction is also defined, which extends from bottom to top with reference to the top and bottom of a user's face.

La rampe de verrouillage 224 a une forme de crochet ouvert vers le bas, avec une première branche 223 orientée avec une composante Z- dirigée de haut en bas et vers l'intérieur du masque et une deuxième branche 225, sensiblement perpendiculaire à la première branche 223 et avec une extrémité libre située au dessous cette première branche 223. Ainsi, si l'utilisateur approche l'écran 206 trop bas, sur le masque 202, l'écran 206 glisse sur la deuxième branche qui le remonte vers la première branche 223, par laquelle il est guidé vers sa position de verrouillage. L'utilisateur approche donc l'écran 206 du couvre face 208 dans un geste simple et naturel et amène l'écran 206 en position de verrouillage dans un mouvement comportant une composante dirigée de haut en bas. De cette manière, l'utilisateur ne peut, lorsqu'il met en place l'écran 206 sur le couvre face 208, que contribuer au bon positionnement du masque 202 sur son visage. Cette disposition est particulièrement importante en situation d'urgence telle que celle qui nécessite généralement le port de l'écran 206.The locking ramp 224 has a downwardly open hook shape, with a first branch 223 oriented with a Z-component directed from top to bottom and towards the inside of the mask and a second branch 225 substantially perpendicular to the first branch. 223 and with a free end located below this first branch 223. Thus, if the user approaches the screen 206 too low, on the mask 202, the screen 206 slides on the second branch which goes back to the first branch 223 , by which it is guided to its locking position. The user thus approaches the screen 206 of the face cover 208 in a simple and natural gesture and brings the screen 206 in the locking position in a movement comprising a component directed from top to bottom. In this way, the user can, when setting up the screen 206 on the face cover 208, that contribute to the proper positioning of the mask 202 on his face. This provision is particularly important in an emergency situation such as that which usually requires the display 206.

Comme illustré par les figures 8 et 10 , la première branch 223 comporte deux glissières 228, disposées de part et d'autre du plan P, symétriquement par rapport à celui-ci, et s'étendent selon la direction Z-. Chaque glissière 228 est surmontée d'une lame de verrouillage 229.As illustrated by Figures 8 and 10 , the first branch 223 comprises two rails 228, disposed on both sides of the plane P, symmetrically with respect thereto, and extend in the direction Z-. Each slide 228 is surmounted by a locking blade 229.

Chaque lame de verrouillage 229 comporte une extrémité libre conformée en ergot 230 s'étendant dans des directions opposées, sensiblement horizontalement et perpendiculairement aux lames de verrouillage 229. Ces lames de verrouillage 229 sont suffisamment souples pour se déformer élastiquement sur un déplacement correspondant sensiblement à la longueur des ergots 230. Chaque ergot 230 comporte un bord droit 231, sensiblement perpendiculaire aux lames de verrouillage 229 et un bord biaisé 232. Chaque bord droit 231 permet de retenir les lames de verrouillages 229 dans l'élément de verrouillage dans lequel elles sont destinées à être introduites. Chaque bord biaisé 232 permet de faciliter leur déformation et leur insertion dans cet élément de verrouillage.Each locking blade 229 has a free end shaped lug 230 extending in opposite directions, substantially horizontally and perpendicularly to the locking blades 229. These locking blades 229 are sufficiently flexible to deform elastically on a displacement substantially corresponding to the length of the lugs 230. Each lug 230 comprises a straight edge 231, substantially perpendicular to the locking blades 229 and a biased edge 232. Each straight edge 231 makes it possible to retain the locking blades 229 in the locking element in which they are intended to be introduced. Each biased edge 232 facilitates their deformation and their insertion in this locking element.

A la base des lames de verrouillage 229, se trouvent deux protubérances 233 formant un point dur comme cela sera expliqué plus loin.At the base of the locking blades 229, there are two protuberances 233 forming a hard point as will be explained later.

L'écran 206 comporte une fenêtre 236 rigide de qualité optique entourée d'un cadre 238 de matière plastique relativement rigide. Le cadre 238 est muni d'un joint d'étanchéité 240 adapté pour appliquer une surface relativement importante au contact du visage de l'utilisateur. L'écran 206 et le masque 202 sont avantageusement prévus de façon à organiser une circulation de gaz respiratoire dans l'écran 206 lorsque ce dernier est en place sur le visage de l'utilisateur. En particulier, lors de la mise en place de l'écran 206 sur le masque 202, la soupape 226, fermée lorsque l'écran 206 n'est pas en place, s'ouvre pour admettre du gaz respiratoire depuis l'intérieur du masque 202 vers l'intérieur de l'écran 206.The screen 206 comprises a window 236 rigid optical quality surrounded by a frame 238 of relatively rigid plastic material. The frame 238 is provided with a seal 240 adapted to apply a relatively large surface in contact with the face of the user. The screen 206 and the mask 202 are advantageously provided so as to organize a flow of breathing gas in the screen 206 when the latter is in place on the face of the user. In particular, during the establishment of the screen 206 on the mask 202, the valve 226, closed when the screen 206 is not in place, opens to admit respiratory gas from inside the mask 202 to the inside of the screen 206.

Le gaz respiratoire peut s'échapper par fuite entre le joint d'étanchéité 240 et la peau. Des fentes peuvent également être prévues dans la partie supérieure du joint d'étanchéité 240 de façon à guider le gaz respiratoire balayant le volume situé entre le visage et l'écran 206. L'ouverture de la soupape 226, lors de la mise en place de l'écran 206 sur le masque 202, est réalisée par l'insertion d'une languette 242 sous un rebord 244 surplombant la soupape 226. Lorsque la languette 242 est insérée sous le rebord 244, elle presse un piston 245 (voir figure 9), ouvrant ainsi un canal d'admission de gaz respiratoire mettant en communication le bloc de connexion 212 au volume situé entre l'écran 206 et le visage de l'utilisateur. Lorsque l'écran 206 est désolidarisé du masque 202, un ressort repousse le piston vers un siège 246 afin de fermer le canal d'admission.Respiratory gas can escape by leakage between seal 240 and the skin. Slots may also be provided in the upper portion of the seal 240 to guide respiratory gas sweeping the volume between the face and the screen 206. The opening of the valve 226, when placing the screen 206 on the mask 202, is achieved by the insertion of a tab 242 under a flange 244 overhanging the valve 226. When the tongue 242 is inserted under the rim 244, it presses a piston 245 (see figure 9 ), thereby opening a breathing gas inlet channel communicating the connection block 212 to the volume located between the screen 206 and the face of the user. When the screen 206 is disengaged from the mask 202, a spring pushes the piston to a seat 246 to close the intake channel.

Comme représenté sur la figure 8, l'écran 206 comporte un nez d'accrochage 250 prévu pour autoriser une mise en place rapide et facile de l'écran 206 sur la coquille 214 du masque 202. Les moyens de verrouillage de l'écran 206 sur le masque 202 peuvent avoir des constitutions très diverses et le mode de réalisation donné ci-dessous n'en est qu'un exemple.As shown on the figure 8 , the screen 206 includes a hooking nose 250 provided to allow a quick and easy installation of the screen 206 on the shell 214 of the mask 202. The screen locking means 206 on the mask 202 may have Constitutions very diverse and the embodiment given below is just one example.

Dans le mode de réalisation, représenté sur la figure 11, le nez d'accrochage comporte un organe de préhension 252, un chariot 254 et un carter de protection 256.In the embodiment, shown in the figure 11 , the attachment nose comprises a gripping member 252, a carriage 254 and a protective casing 256.

L'organe de préhension 252 est monté coulissant sur le chariot 254. Un ressort 249 est intercalé entre le chariot 254 et une clé 263, un axe 264 lié à l'organe de préhension 252, passant au milieu du ressort 249. Le ressort 249 est situé de l'autre côté de l'organe de préhension 252, par rapport à la clé 263. Le ressort 249 est en compression. Il tend à écarter l'organe de préhension 252 et le chariot 254 l'un de l'autre.The gripping member 252 is slidably mounted on the carriage 254. A spring 249 is interposed between the carriage 254 and a key 263, an axis 264 connected to the gripping member 252, passing through the middle of the spring 249. The spring 249 is located on the other side of the gripping member 252, with respect to the key 263. The spring 249 is in compression. It tends to move the gripping member 252 and the carriage 254 away from each other.

Le chariot 254 comporte des glissières 255 destinées à coopérer avec les première 223 et deuxième 225 branches de la rampe de verrouillage 224. Lorsque l'écran 206 est verrouillé sur le masque 202, le chariot 254 est donc fixe par rapport au masque 202.The carriage 254 comprises slides 255 intended to cooperate with the first 223 and second 225 branches of the locking ramp 224. When the screen 206 is locked on the mask 202, the carriage 254 is fixed with respect to the mask 202.

Le chariot 254 est monté sur le cadre 238 par l'intermédiaire d'une première 257 et d'une deuxième biellettes 258. Comme représenté sur la figure 12, Les première 257 et deuxième 258 biellettes permettent au cadre 238, et donc à l'écran 206, de pivoter autour d'un axe de rotation C de manière à rattraper un jeu au niveau du bord supérieur 261 du joint d'étanchéité 240, par un déplacement sensiblement horizontal pouvant aller jusqu'à environ 10mm.The carriage 254 is mounted on the frame 238 via a first 257 and a second link 258. As shown in FIG. figure 12 , The first 257 and second 258 links allow the frame 238, and therefore the screen 206, to pivot about an axis of rotation C so as to catch a game at the upper edge 261 of the seal 240, by a substantially horizontal displacement of up to about 10mm.

Revenant à la figure 7, le cadre 238 comporte des pattes de guidage 239 destinées à s'insérer, sans manipulation supplémentaire de la part de l'utilisateur, sous les sangles 205 du harnais, lorsque l'utilisateur positionne l'écran sur le masque 202. Plus précisément, les sangles sont munies de colliers 207, au niveau des lieux d'insertion des pattes de guidage 239. Ces colliers 207 facilitent l'insertion des pattes de guidages 239 sous les sangles 205. En outre, les pattes de guidage 239 sont conformées de manière à faire remonter les sangles 205 sur les côtés du cadre 238, afin d'appliquer plus efficacement le joint d'étanchéité 240 sur le visage de l'utilisateur.Returning to figure 7 , the frame 238 includes guide tabs 239 intended to be inserted, without additional manipulation by the user, under the straps 205 of the harness, when the user positions the screen on the mask 202. More specifically, the straps are provided with collars 207, at the places of insertion of the guide tabs 239. These collars 207 facilitate the insertion of the guide tabs 239 under the straps 205. In addition, the guide tabs 239 are shaped to raise the straps 205 on the sides of the frame 238, in order to more effectively apply the seal 240 on the face of the user.

Revenant à la figure 11, un doigt de ventilation 259 est rigidement lié au chariot 254. Le doigt de ventilation 259 est surmonté de la languette 242, qui est donc fixe par rapport au masque 202, lorsque l'écran 206 est fixé au masque 202. Un ressort d'écran 260 est intercalé entre le doigt de ventilation 259 et le cadre 238. Ainsi, ce ressort d'écran 260 sollicite l'écran 206 vers l'arrière, c'est-à-dire vers le visage de l'utilisateur lorsque l'équipement 201 est en position d'utilisation sur la tête de cet utilisateur.Returning to figure 11 , a ventilation finger 259 is rigidly connected to the carriage 254. The ventilation finger 259 is surmounted by the tongue 242, which is fixed with respect to the mask 202, when the screen 206 is fixed to the mask 202. A spring of The screen 260 is interposed between the ventilation finger 259 and the frame 238. Thus, this screen spring 260 biases the screen 206 rearwardly, that is to say towards the face of the user when the equipment 201 is in use position on the head of this user.

Le carter de protection 256 recouvre le chariot 254, dans l'espace variable laissé entre le cadre 238 et l'organe de préhension 252, tout en autorisant le mouvement des pièces mobiles, chariot 254 et organe de préhension 252.The protective casing 256 covers the carriage 254, in the variable space left between the frame 238 and the gripping member 252, while allowing the movement of the moving parts, carriage 254 and gripping member 252.

Lorsque l'utilisateur, portant déjà le masque 202 sur le visage, souhaite s'équiper de l'écran 206, il s'empare de l'écran 206 par l'organe de préhension 252 et l'amène vers le masque 202. A proximité du masque 202, le positionnement de l'écran 206 est facilité par la rampe de verrouillage 224. Lorsque l'écran 206 est sensiblement correctement positionné sur le masque 202, l'utilisateur continue de presser l'organe de préhension 252 vers le masque 202. Comme illustré par la figure 13, l'organe de préhension 252 est muni de deux lames souples 253 qui, passant le point dur constitué par les protubérances 233, viennent taper sur la coquille 214 et produisent ainsi un témoin sonore du verrouillage de l'écran 206 sur le masque 202. En pressant ainsi l'organe de préhension 252 vers le masque 202, l'utilisateur a entraîné le chariot 254, qui est mobile par rapport à l'organe de préhension 252 et qui vient dans ce cas en butée contre celui-ci. Ainsi, les lames de verrouillage 229 se sont déformées pour pénétrer dans le chariot 254, puis se sont redressées élastiquement vers une position de repos dans laquelle leurs bords droits 231 coopèrent avec le chariot 254 pour retenir le nez de verrouillage 250 sur le masque 202.When the user, already wearing the mask 202 on the face, wishes to equip the screen 206, he seizes the screen 206 by the gripping member 252 and brings it to the mask 202. A near the mask 202, the positioning of the screen 206 is facilitated by the locking ramp 224. When the screen 206 is substantially correctly positioned on the mask 202, the user continues to press the gripping member 252 towards the mask 202. As illustrated by figure 13 , the gripping member 252 is provided with two flexible blades 253 which, passing the hard point constituted by the protuberances 233, strike the shell 214 and thus produce a sound indicator of the locking of the screen 206 on the mask 202. By thus pressing the gripping member 252 towards the mask 202, the user has driven the carriage 254, which is movable relative to the gripping member 252 and which in this case abuts against it. Thus, the locking blades 229 have deformed to penetrate the carriage 254, then elastically straightened to a rest position in which their straight edges 231 cooperate with the carriage 254 to retain the locking nose 250 on the mask 202.

Comme illustré par la figure 14, chaque ergot 230 est muni dans sa partie inférieure, d'une pente de déverrouillage 234.As illustrated by figure 14 each lug 230 is provided in its lower part with an unlocking slope 234.

La figure 15 correspond à une coupe passant par les pentes de déverrouillage 234. A ce niveau, l'organe de préhension comporte des griffes 235.The figure 15 corresponds to a section passing through the unlocking slopes 234. At this level, the gripping member comprises claws 235.

Pour retirer l'écran 206, à partir de la position d'utilisation illustrée par la figure 15, l'utilisateur tire sur l'organe de préhension 252. Celui-ci coulisse le long du chariot 254. Ainsi, les griffes 235 coopèrent avec les pentes de déverrouillage 234, sollicitant les lames de verrouillage 229 l'une vers l'autre. Le chariot 254 est entraîné par l'organe de préhension 252, d'une part grâce au ressort 249 et d'autre part grâce aux butées 262 (voir figure 13). Les ergots s'escamotent alors et les bords droits 231 se dégagent du chariot 254. Les lames souples se dégagent simultanément des protubérances 233. L'écran 206 est donc retiré du masque 202, sans nécessiter de la part de l'utilisateur d'opération combinée. Un seul geste simple suffit pour désolidariser l'écran 206 du masque 202.To remove the screen 206, from the position of use illustrated by the figure 15 , the user pulls on the gripping member 252. The latter slides along the carriage 254. Thus, the claws 235 cooperate with the unlocking slopes 234, biasing the locking blades 229 towards each other. The carriage 254 is driven by the gripping member 252, on the one hand by the spring 249 and on the other hand by the stops 262 (see figure 13 ). The lugs then retract and the straight edges 231 emerge from the carriage 254. The flexible blades emerge simultaneously protrusions 233. The screen 206 is removed from the mask 202, without requiring the user of operation combined. A single simple gesture is sufficient to separate the screen 206 from the mask 202.

Lorsque l'utilisateur ôte l'écran, les pattes de guidages 239 passent sous les colliers 207 pour dégager l'écran des sangles 205.When the user removes the screen, the guide tabs 239 pass under the collars 207 to disengage the screen from the straps 205.

Bien entendu, une ou des caractéristique(s) décrite(s) en relation avec l'un ou l'autre des deux modes de réalisation décrits ci-dessus, pourra(pourront) être combinée(s) et/ou interchangée(s) pour donner lieu à des variantes de l'équipement de protection selon l'invention.Of course, one or more characteristics described in relation to one or the other of the two embodiments described above, may (may) be combined and / or interchanged (s) to give rise to variants of the protective equipment according to the invention.
