Description

Description Description
Titre de l'invention : Ensemble de protection individuelle contre les Title of the invention: Personal protective equipment against
agressions NRBC CBRN attacks
Domaine technique de l’invention Technical field of the invention
[0001 ] L’invention relève des dispositifs de protection individuelle, notamment à usage militaire, et concerne plus particulièrement un ensemble de protection individuelle contre les agressions nucléaires, radiologiques, biologiques et chimiques, connues de l’homme du métier sous le sigle « NRBC ». The invention relates to individual protection devices, in particular for military use, and relates more particularly to a set of individual protection against nuclear, radiological, biological and chemical attacks, known to those skilled in the art under the acronym "NRBC ".
Technique antérieure Prior art
[0002] Les dispositifs de protection individuelle contre les agressions NRBC sont notamment formés par des articles d’habillement. [0002] Individual protection devices against CBRN attacks consist in particular of articles of clothing.
[0003] Ces articles d’habillement, lorsqu’ils sont portés par un utilisateur, couvrent en partie ou en totalité son corps afin de préserver sa peau ou ses muqueuses de tout contact avec des agents contaminants, notamment sous forme liquide ou gazeuse. [0003] These articles of clothing, when worn by a user, cover their body in part or in full in order to protect their skin or mucous membranes from contact with contaminants, in particular in liquid or gas form.
[0004] Ces articles d’habillement comprennent généralement une couche externe destinée à assurer la résistance mécanique de l’article d’habillement et à garantir une protection contre les agents contaminants sous forme liquide. Cette dernière est généralement obtenue par l'application d'un traitement hydrophobe et/ou oléophobe. [0004] These articles of clothing generally comprise an outer layer intended to ensure the mechanical resistance of the article of clothing and to guarantee protection against contaminants in liquid form. The latter is generally obtained by applying a hydrophobic and / or oleophobic treatment.
[0005] La couche externe est généralement superposée à une couche interne réalisée à partir d’un matériau filtrant destiné à filtrer les agents contaminants sous forme gazeuse. Cette filtration est obtenue par exemple grâce à l’utilisation de charbon actif, aussi appelé carbone activé. [0005] The outer layer is generally superimposed on an inner layer made from a filter material intended to filter contaminants in gaseous form. This filtration is obtained for example through the use of activated carbon, also called activated carbon.
[0006] Les couches externe et interne sont assemblées l’une à l’autre de façon continue. [0006] The outer and inner layers are assembled together on a continuous basis.
[0007] Lorsque l’utilisateur porte plusieurs articles d’habillement, notamment un vêtement destiné à recouvrir la partie supérieure de son corps et un pantalon destiné à recouvrir la partie inférieure de son corps, l’interface entre ces articles d’habillement attenants constitue une zone à risque pour l’utilisateur susceptible de laisser pénétrer à l’intérieur du vêtement, les agents contaminants sous forme liquide, gazeuse et aérosol. [0008] En effet, les deux articles d’habillement attenants sont susceptibles de s’écarter l’un de l’autre dans certaines circonstances, par exemple selon certains mouvements réalisés par l’utilisateur ou selon certaines positions occupées par ce dernier, et ainsi de découvrir l’utilisateur sur une zone pouvant entrer en contact avec d’éventuels agents contaminants sous forme liquide, gazeuse et aérosol présents dans l’environnement extérieur. [0007] When the user wears several articles of clothing, in particular a garment intended to cover the upper part of his body and pants intended to cover the lower part of his body, the interface between these adjoining articles of clothing constitutes a zone at risk for the user likely to let penetrate inside the garment, contaminating agents in liquid, gaseous and aerosol form. [0008] Indeed, the two adjoining articles of clothing are liable to deviate from one another in certain circumstances, for example according to certain movements made by the user or according to certain positions occupied by the latter, and thus discovering the user in an area that may come into contact with any contaminating agents in liquid, gaseous and aerosol form present in the external environment.
[0009] Il existe donc un besoin de garantir à un utilisateur une protection à l’interface entre plusieurs articles d’habillement d’un dispositif de protection individuelle contre les agressions NRBC. [0009] There is therefore a need to guarantee a user protection at the interface between several articles of clothing of a personal protection device against CBRN attacks.
Présentation de l'invention Presentation of the invention
[0010] La présente invention a notamment pour but de fournir un ensemble de protection individuelle contre les effets d’agents contaminants sous toutes formes apportant une solution efficace pour protéger un utilisateur notamment au niveau des interfaces entre différents articles d’habillement dont est composé ledit ensemble de protection. The present invention aims in particular to provide a set of individual protection against the effects of contaminating agents in all forms providing an effective solution to protect a user in particular at the level of the interfaces between different articles of clothing of which said is composed. protection set.
[001 1 ] À cet effet, l’invention concerne un ensemble de protection individuelle d’un utilisateur contre un agent contaminant sous toutes formes, par exemple liquide, gazeuse ou aérosol, comportant un vêtement destiné à recouvrir la partie supérieure du corps de l’utilisateur et un pantalon destiné à recouvrir la partie inférieure du corps de l’utilisateur. Le vêtement comprend des manches et un col opposé à une ouverture de tronc destinée à recevoir en engagement le tronc de l’utilisateur. To this end, the invention relates to a set of individual protection of a user against a contaminating agent in any form, for example liquid, gas or aerosol, comprising a garment intended to cover the upper part of the body of the user and pants intended to cover the lower part of the user's body. The garment includes sleeves and a collar opposite a trunk opening for engaging the user's trunk.
[0012] Le vêtement comprend dans son épaisseur d’un environnement extérieur vers son corps : [0012] The garment comprises in its thickness from an external environment towards its body:
[0013] - une couche externe perméable à l’air, configurée pour stopper l’agent contaminant sous sa forme liquide, et présentant une double caractéristique hydrophobe et/ou oléophobe, - an outer layer permeable to air, configured to stop the contaminating agent in its liquid form, and having a dual hydrophobic and / or oleophobic characteristic,
[0014] - une couche interne perméable à l’air et configurée pour absorber et/ou adsorber un agent contaminant sous forme gazeuse. [0014] an inner layer permeable to air and configured to absorb and / or adsorb a contaminating agent in gaseous form.
[0015] Les couches externe et interne sont non liées l’une avec l’autre, c’est-à- dire qu’elles sont libres l’une par rapport à l’autre, au niveau de l’ouverture de tronc de sorte que lorsque l’ensemble de protection est porté par un utilisateur, le pantalon puisse être interposé entre lesdites couches externe et interne. [0015] The outer and inner layers are not linked to one another, that is to say they are free with respect to each other, at the level of the trunk opening of so that when the protective assembly is worn by a user, the pants can be interposed between said outer and inner layers.
[0016] Ainsi, contrairement à l’existant qui consiste à fixer entre elles les couches externe et interne de façon continue sur leurs pourtours, la solution de la présente invention consiste à ne pas lier les couches externe et interne au niveau de l’ouverture de tronc afin de pouvoir intercaler le pantalon entre lesdites couches externe et interne. [0016] Thus, unlike the existing one which consists in fixing the outer and inner layers between them continuously on their peripheries, the solution of the present invention consists in not binding the outer and inner layers at the opening. trunk in order to be able to insert the pants between said outer and inner layers.
[0017] Cette caractéristique permet la création d’un chemin tortueux entre le milieu extérieur et le corps de l’utilisateur empêchant toute progression d’un éventuel agent contaminant sous forme gazeuse jusqu’au corps dudit utilisateur. This characteristic allows the creation of a tortuous path between the external environment and the body of the user preventing any progression of any contaminating agent in gaseous form to the body of said user.
[0018] En effet, grâce à cette caractéristique, l’absorption et/ou l’adsorption complète d’un agent contaminant sous forme gazeuse est assurée dans le cas d’une éventuelle pénétration dudit agent contaminant entre les couches interne et externe. [0018] Indeed, thanks to this characteristic, the absorption and / or complete adsorption of a contaminating agent in gaseous form is ensured in the event of any penetration of said contaminating agent between the inner and outer layers.
[0019] Dans des modes particuliers de réalisation, l’invention répond en outre aux caractéristiques suivantes, mises en oeuvre séparément ou en chacune de leurs combinaisons techniquement opérantes. [0019] In particular embodiments, the invention further meets the following characteristics, implemented separately or in each of their technically operative combinations.
[0020] Dans des modes particuliers de réalisation de l’invention, les couches externe et interne présentent au niveau de l’ouverture, une forme de fourreau de circonférence continue s’étendant sur une certaine longueur vers le col. [0020] In particular embodiments of the invention, the outer and inner layers have, at the opening, a form of continuous circumference sheath extending over a certain length towards the neck.
[0021 ] On comprend ici que la forme de fourreau de chacune des couches externe et interne est destinée à être en vis-à-vis du pantalon sur une partie de sa surface, lorsque l’ensemble de protection est porté par l’utilisateur. [0021] It is understood here that the sheath shape of each of the outer and inner layers is intended to be facing the pants over part of its surface, when the protective assembly is worn by the user.
[0022] Cette caractéristique permet de garantir l’efficacité de la protection fournie par l’ensemble de protection dans la mesure où les couches externe et interne présentent respectivement des caractéristiques uniformes sur l’ensemble de la surface de leur forme de fourreau. [0022] This characteristic makes it possible to ensure the effectiveness of the protection provided by the protection assembly insofar as the outer and inner layers respectively have uniform characteristics over the entire surface of their sheath form.
[0023] Dans des modes particuliers de réalisation de l’invention, la couche externe et la couche interne sont assemblées ponctuellement l’une à l’autre par exemple par un point ou une zone de fixation plus proche du col que de l’ouverture. [0024] Cette caractéristique permet d’une part d’autoriser un certain degré de liberté entre les couches externe et interne favorisant le confort de l’utilisateur, et d’autre part de faciliter l’équipement de l’ensemble de protection individuelle. In particular embodiments of the invention, the outer layer and the inner layer are punctually assembled to one another, for example by a point or an attachment zone closer to the neck than to the opening. . This feature allows on the one hand to allow a certain degree of freedom between the outer and inner layers favoring the comfort of the user, and on the other hand to facilitate the fitting of the personal protective assembly.
[0025] Cette liaison entre la couche externe et la couche interne peut être amovible de sorte à pouvoir séparer lesdites couches externe et interne l’une de l’autre. [0025] This connection between the outer layer and the inner layer may be removable so as to be able to separate said outer and inner layers from one another.
[0026] Dans des modes particuliers de réalisation de l’invention, l’ensemble de protection individuelle comprend une couche intermédiaire interposée entre la couche interne et la couche externe et configurée pour absorber et/ou adsorber un agent contaminant sous forme d’aérosol. [0026] In particular embodiments of the invention, the personal protection assembly comprises an intermediate layer interposed between the inner layer and the outer layer and configured to absorb and / or adsorb a contaminating agent in the form of an aerosol.
[0027] Ainsi, l’ensemble de protection peut assurer une protection de l’utilisateur contre les agents contaminants sous forme de particules fines solides ou liquides. [0027] Thus, the protection assembly can provide user protection against contaminants in the form of fine solid or liquid particles.
[0028] La couche intermédiaire peut être soit assemblée à la couche interne et/ou à la couche externe, soit libre par rapport auxdites couches interne et externe. The intermediate layer can be either assembled to the inner layer and / or to the outer layer, or free with respect to said inner and outer layers.
[0029] Dans des modes particuliers de réalisation de l’invention, la couche intermédiaire est réalisée en textile non tissé, par exemple en polypropylène, et est traitée hydrophobe. [0029] In particular embodiments of the invention, the intermediate layer is made of non-woven fabric, for example polypropylene, and is hydrophobic treated.
Brève description des figures Brief description of the figures
[0030] L’invention sera mieux comprise à la lecture de la description suivante, donnée à titre d’exemple nullement limitatif, et faite en se référant aux figures suivantes : [0030] The invention will be better understood on reading the following description, given by way of non-limiting example, and made with reference to the following figures:

Each handle 112 has a proximal end by which it is connected to the ventral and dorsal parts, said proximal end being opposite a distal end.
[0040] Le vêtement 10, comporte, dans son épaisseur, d’un environnement extérieur dans lequel évolue l’utilisateur le portant dans des conditions normales d’utilisation, vers le corps dudit utilisateur : The garment 10 comprises, in its thickness, from an external environment in which the user wearing it under normal conditions of use, towards the body of said user:
- une première couche textile, dite « couche externe » 1 1 , perméable à l’air, configurée pour stopper un agent contaminant sous forme liquide, et présentant une double caractéristique hydrophobe et/ou oléophobe, et - a first textile layer, called "outer layer" 11, permeable to air, configured to stop a contaminating agent in liquid form, and having a dual hydrophobic and / or oleophobic characteristic, and
- une deuxième couche textile, dite « couche interne » 12, perméable à l’air et configurée pour absorber et/ou adsorber un agent contaminant sous forme gazeuse. [0041 ] On comprend ici que les couches externe 1 1 et interne 12 comprennent chacune un col 1 10, une ouverture 1 1 1 et des manches 1 12. a second textile layer, called “inner layer” 12, permeable to air and configured to absorb and / or adsorb a contaminating agent in gaseous form. It is understood here that the outer 1 1 and inner 12 layers each comprise a neck 1 10, an opening 1 1 1 and sleeves 1 12.
[0042] Dans un exemple de réalisation de l’invention, les couches externe 1 1 et interne 12 comprennent également une capuche 1 13. In an exemplary embodiment of the invention, the outer 1 1 and inner 12 layers also include a hood 1 13.
[0043] Les couches externe 1 1 et interne 12 sont perméables à l’air. The outer 1 1 and inner 12 layers are permeable to air.
[0044] La couche externe 1 1 est avantageusement conçue de sorte à résister aux contraintes mécaniques, notamment à l'abrasion et aux déchirures. The outer layer 1 1 is advantageously designed so as to withstand mechanical stresses, in particular abrasion and tears.
[0045] Comme représenté schématiquement sur la figure 1 , la couche externe 1 1 est avantageusement dimensionnée de sorte à recouvrir partiellement le pantalon 20 lorsque l’ensemble de protection individuelle 30 est porté par un utilisateur, afin de protéger ledit utilisateur de toute projection d’un agent contaminant liquide. As shown schematically in Figure 1, the outer layer 1 1 is advantageously sized so as to partially cover the pants 20 when the personal protective assembly 30 is worn by a user, in order to protect said user from any projection of 'a liquid contaminant.
[0046] Plus particulièrement, la couche externe 1 1 est préférentiellement dimensionnée de sorte que, quels que soient les mouvements de l’utilisateur, le vêtement 10 recouvre toujours ledit utilisateur et en particulier, recouvre toujours la partie supérieure du pantalon 20. More particularly, the outer layer 11 is preferably sized so that, whatever the movements of the user, the garment 10 always covers said user and in particular always covers the upper part of the pants 20.
[0047] Elle présente une surface intérieure orientée vers l’utilisateur lorsque ce dernier est équipé du vêtement 10, opposée à une surface extérieure en vis-à-vis de l’environnement extérieur. It has an inner surface oriented towards the user when the latter is equipped with the garment 10, opposite an outer surface facing the external environment.
[0048] La couche interne 12, en partie représentée par les traits discontinus sur la figure 1 , est agencée à l’intérieur et de la couche externe 1 1 , contre sa surface intérieure. La couche interne 12 est destinée à être en contact direct ou indirect avec le corps de l’utilisateur lorsqu’il porte le vêtement 10. The inner layer 12, partly shown by the broken lines in Figure 1, is arranged inside and of the outer layer 1 1, against its inner surface. The inner layer 12 is intended to be in direct or indirect contact with the body of the user when he is wearing the garment 10.
[0049] Le textile de la couche interne comporte un milieu absorbant et/ou adsorbant par exemple composé de charbons actifs, de zéolithes et de catalyseurs, etc. Le milieu adsorbant est préférentiellement intégré au sein du textile sous forme de poudre, de billes ou encore de fibres. The textile of the inner layer comprises an absorbent and / or adsorbent medium, for example composed of activated carbon, zeolites and catalysts, etc. The adsorbent medium is preferably integrated within the textile in the form of powder, beads or even fibers.
[0050] La couche externe 11 et la couche interne 12 sont préférentiellement assemblées entre elles ponctuellement, c’est-à-dire selon une zone ou un point de fixation isolé, par exemple, plus proche du col 110 que de l’ouverture de tronc 1 11. The outer layer 11 and the inner layer 12 are preferably assembled together punctually, that is to say according to an area or an isolated attachment point, for example, closer to the neck 110 than to the opening of trunk 1 11.
[0051 ] Plus particulièrement, avantageusement, les couches externe 1 1 et interne 12 ne sont pas fixées l’une à l’autre au niveau de l’ouverture 1 11 , afin de permettre l’insertion du pantalon 20 entre lesdites couches externe 1 1 et interne 12 lorsque l’ensemble de protection 30 est porté par un utilisateur. More particularly, advantageously, the outer 1 1 and inner 12 layers are not fixed to each other at the opening 1 11, in order to allow the insertion of the pants 20 between said outer 1 1 and inner 12 layers when the protective assembly 30 is worn by a user.
[0052] Cette caractéristique permet avantageusement de garantir une protection optimale à l’utilisateur dans la mesure où à l’interface entre la couche interne 12, le pantalon 20 et la couche externe 1 1 , un chemin tortueux est formé entre le milieu extérieur et le corps de l’utilisateur empêchant toute progression d’un éventuel agent contaminant, quelle que soit sa forme, vers le corps dudit utilisateur. This characteristic advantageously makes it possible to guarantee optimum protection to the user insofar as at the interface between the inner layer 12, the pants 20 and the outer layer 1 1, a tortuous path is formed between the external environment and the user's body preventing any progression of any contaminating agent, whatever its form, towards the body of said user.
[0053] En effet, dans le cas où un agent contaminant sous forme gazeuse arriverait à pénétrer sous la couche externe 1 1 , il serait absorbé et/ou adsorbé par la couche interne 12 et ne pourrait progresser au-delà du pantalon 20, ledit pantalon 20 formant une barrière protectrice. Indeed, in the event that a contaminating agent in gaseous form would manage to penetrate under the outer layer 1 1, it would be absorbed and / or adsorbed by the inner layer 12 and could not progress beyond the pants 20, said pants 20 forming a protective barrier.
[0054] La couche interne 12 peut être assemblée de manière permanente ou de manière amovible à la couche externe 1 1 , par exemple par couture, par soudage ou par collage, ou de manière amovible, par exemple par des éléments d’emboitage élastique ou par des éléments auto-agrippant. The inner layer 12 can be assembled permanently or removably to the outer layer 1 1, for example by sewing, by welding or by gluing, or removably, for example by elastic fitting elements or by self-gripping elements.
[0055] Préférentiellement, la couche interne 12 et la couche externe 1 1 sont en outre fixées l’une à l’autre par couture sur le pourtour de l’ouverture faciale de la capuche 1 13. Preferably, the inner layer 12 and the outer layer 11 are further secured to each other by stitching around the periphery of the facial opening of the hood 1113.
[0056] Avantageusement, la couche externe 1 1 et la couche interne 12 présentent, sur un segment de leur longueur s’étendant depuis l’ouverture 1 1 1 , une forme de fourreau de circonférence continue, c’est-à-dire qu’elles ne présentent pas de dispositif de fermeture, tel qu’une fermeture à glissière ou une fermeture auto-agrippante. Advantageously, the outer layer 1 1 and the inner layer 12 have, on a segment of their length extending from the opening 1 1 1, a form of continuous circumference sleeve, that is to say that 'they do not have a closure device, such as a zipper or a hook-and-loop fastener.
[0057] Plus particulièrement, on entend par les termes « circonférence continue » que la circonférence de chaque couche externe 1 1 et interne 12 est fermée et indivisible. Dans cette définition est incluse d’éventuelles coutures. Ainsi, en tout point de sa surface, la couche externe 1 1 présente uniformément sensiblement les mêmes caractéristiques, de même que la couche interne 12. Le corps de l’utilisateur, et notamment son tronc, lorsqu’il est engagé à travers cette forme de fourreau, est donc protégé de façon optimale. [0058] Préférentiellement, comme le montre schématiquement la figure 2, l’ensemble de protection individuelle 30 comprend en outre une couche intermédiaire 13 interposée entre la couche externe 1 1 et la couche interne 12. Dans des exemples de réalisation de l’invention, la couche intermédiaire 13 peut être assemblée, par exemple, cousue ou laminée à la couche interne 12. More particularly, by the terms "continuous circumference" is meant that the circumference of each outer 1 1 and inner 12 layer is closed and indivisible. In this definition is included any seams. Thus, at any point of its surface, the outer layer 1 1 uniformly has substantially the same characteristics, as does the inner layer 12. The user's body, and in particular his trunk, when engaged through this form sheath, is therefore optimally protected. Preferably, as shown schematically in Figure 2, the individual protection assembly 30 further comprises an intermediate layer 13 interposed between the outer layer 1 1 and the inner layer 12. In exemplary embodiments of the invention, the intermediate layer 13 can be assembled, for example, sewn or laminated to the inner layer 12.
[0059] Alternativement, la couche intermédiaire 13 peut être assemblée, par exemple cousue ou laminée, contre la surface intérieure de la couche externe 1 1. Alternatively, the intermediate layer 13 can be assembled, for example sewn or laminated, against the inner surface of the outer layer 1 January.
[0060] La couche intermédiaire 13 est réalisée en matériau non tissé, préférentiellement en polypropylène traité hydrophobe. The intermediate layer 13 is made of nonwoven material, preferably of hydrophobic treated polypropylene.
[0061 ] Cette couche intermédiaire 13 permet avantageusement de protéger l’utilisateur contre des agents contaminants sous forme aérosol, c’est-à- dire sous forme de particules fines solides ou liquides, et en particulier contre les aérosols d’origine biologiques tels que les bactéries et les virus. This intermediate layer 13 advantageously makes it possible to protect the user against contaminating agents in aerosol form, that is to say in the form of fine solid or liquid particles, and in particular against aerosols of biological origin such as bacteria and viruses.
[0062] Le pantalon 20 comporte une première couche comportant un matériau, par exemple un textile, comprenant un traitement hydrophobe et/ou oléophobe afin de protéger l’utilisateur contre toute agression d’agent contaminant sous forme liquide et une deuxième couche comportant un matériau, par exemple un textile, destiné à assurer la filtration d’agents contaminants sous forme gazeuse. The pants 20 comprises a first layer comprising a material, for example a textile, comprising a hydrophobic and / or oleophobic treatment in order to protect the user against any attack from a contaminating agent in liquid form and a second layer comprising a material , for example a textile, intended to ensure the filtration of contaminating agents in gaseous form.
[0063] On comprend ici que le matériau de la première couche du pantalon 20 est analogue à celui de la couche externe 1 1 du vêtement 10 et que le matériau de la deuxième couche du pantalon 20 est analogue à celui de la couche interne 12 du vêtement 10. It is understood here that the material of the first layer of the pants 20 is similar to that of the outer layer 11 of the garment 10 and that the material of the second layer of the pants 20 is similar to that of the inner layer 12 of the clothing 10.
[0064] Les première et deuxième couches du pantalon 20 sont préférentiellement assemblés l’une à l’autre par couture au moins sur le pourtour de la taille du pantalon 20. [0064] The first and second layers of pants 20 are preferably assembled together by stitching at least around the waist circumference of pants 20.
[0065] Pour des raisons de clarté et pour simplifier la lecture des figures, les première et deuxième couches du pantalon 20 sont représentées sous la forme d’une unique couche sur les figures 1 et 2. For reasons of clarity and to simplify reading of the figures, the first and second layers of pants 20 are shown in the form of a single layer in Figures 1 and 2.
[0066] Préférentiellement, l’ensemble de protection individuelle 30 comporte un système de suspension, par exemple une paire de bretelles 21 , destiné à relier l’un avec l’autre le vêtement 10 et le pantalon 20. [0067] Dans l’exemple de réalisation représenté sur la figure 1 , chaque bretelle 21 comporte un lien 21 1 dont une première extrémité comprend un anneau 212 à travers lequel est engagé ledit lien 211 de sorte à former une boucle 210. Preferably, the individual protection assembly 30 comprises a suspension system, for example a pair of suspenders 21, intended to connect the garment 10 and the pants 20 with one another. In the embodiment shown in Figure 1, each strap 21 comprises a link 21 1, a first end of which comprises a ring 212 through which is engaged said link 211 so as to form a loop 210.
[0068] Les bretelles 21 sont agencées de sorte que la boucle formée par chaque lien 21 1 entoure l’extrémité proximale d’une manche 1 12 et est introduit à travers un manchon ou un oeillet (non représentés sur les figures) fixé sur la surface intérieure de la couche externe 11 et dans lequel il est libre de coulisser. The straps 21 are arranged so that the loop formed by each link 21 1 surrounds the proximal end of a sleeve 1 12 and is introduced through a sleeve or an eyelet (not shown in the figures) fixed on the inner surface of the outer layer 11 and in which it is free to slide.
[0069] Avantageusement, l’anneau 212 est mobile en coulissement le long du lien 21 1 de sorte à modifier la dimension de la boucle 210 selon les mouvements réalisés par l’utilisateur. Advantageously, the ring 212 is movable in sliding along the link 21 1 so as to modify the dimension of the loop 210 according to the movements made by the user.
[0070] Cette caractéristique participe à augmenter le confort de l’utilisateur en favorisant sa liberté de mouvements. This feature helps to increase the comfort of the user by promoting their freedom of movement.
[0071 ] Chaque lien 21 1 présente, à sa seconde extrémité, un élément de fixation configuré pour coopérer de façon amovible avec un élément de fixation agencé sur le pantalon 20, de sorte à fixer la couche externe 1 1 avec ledit pantalon 20. Each link 21 1 has, at its second end, a fastening element configured to cooperate removably with a fastening element arranged on the pants 20, so as to fix the outer layer 1 1 with said pants 20.
[0072] Les éléments de fixation du lien 21 1 et du pantalon 20 peuvent avantageusement être formés par des éléments d’emboitage élastique, par exemple du type mâle/femelle. The fixing elements of the link 21 1 and of the pants 20 can advantageously be formed by elastic fitting elements, for example of the male / female type.
[0073] Cette caractéristique permet d’assurer une liaison entre la couche externe 1 1 et le pantalon 20 lorsque l’ensemble de protection individuelle 30 est porté par l’utilisateur, et ainsi de prévenir tout risque de fuite d’agent contaminant à l’intérieur dudit ensemble, quels que soient les mouvements de l’utilisateur. This characteristic makes it possible to ensure a connection between the outer layer 1 1 and the pants 20 when the personal protective assembly 30 is worn by the user, and thus to prevent any risk of leakage of contaminating agent to the 'inside said assembly, regardless of the movements of the user.
[0074] De manière plus générale, il est à noter que les modes de mise en oeuvre et de réalisation de l’invention considérés ci-dessus ont été décrits à titre d’exemples non limitatifs et que d’autres variantes sont par conséquent envisageables. More generally, it should be noted that the embodiments and embodiments of the invention considered above have been described by way of non-limiting examples and that other variants are therefore possible. .
