Description

Hoods, in particular hoods or balaclava, for protective clothing

The present invention relates to the technical field of protective clothing with a protective function against chemical, biological, radioactive or nuclear toxins or pollutants (for example warfare agents), such as can be used in particular in the military and civilian sector (NBC protective clothing or CBRN protective clothing , with ABC = atomic, biological and chemical as well as with CBRN = chemical, biological, radioactive and nuclear [whereby the terms CBRN on the one hand and ABC on the other hand are used synonymously]). In this context, the present invention relates in particular to the technical field of protective clothing specially designed for the head or neck area, namely in the form of a hood which, in particular, is used together with a respirator (synonymously also referred to as a respirator, protective mask, mask, respiratory mask or the like) is worn or is used.

Against this background, the present invention relates in particular to a hood or hood which is designed in particular in the form of a hood or balaclava and which can preferably be used for or as protective clothing.

The present invention also relates to the use of the hood according to the invention in, for or as protective clothing or as a component or part of protective clothing, which can be used in particular for the civil or military sector.

The present invention also relates to an item of protective clothing as such which has the head cover according to the invention or which is produced using the head cover according to the invention.

In addition, the present invention also relates to the use of a sealing element in combination with an edge section or the use of a combination of a sealing element on the one hand and an edge section on the other hand to seal the transition between a hood on the one hand and a respirator or a mask body on which the respirator is based (also synonymous as Respirator body or respiratory protection device body or body, mask body or the like) on the other hand.

Finally, the present invention also relates to a method for sealing the transition between a hood on the one hand and a respiratory protection mask or a mask body on which a respiratory protection mask is based on the other hand.

It is generally indicated for people, such as soldiers, firefighters, police officers, members of special units or the like, who are at risk of coming into contact with poisonous or harmful substances that can be absorbed or resorbed via the respiratory tract and it is necessary to ensure appropriate protection against these poisonous or harmful substances, among other things by wearing respiratory masks (ABC respirators or CBRN protective masks). In addition, it is often the case that poisonous or harmful substances are also absorbed or resorbed through the skin of an affected person, which represents a further high risk potential. In this respect, too, it is often necessary that appropriate people wear appropriate protective clothing (ABC or CBRN protective clothing) in addition to a respiratory mask in order to avoid contact of the toxins or pollutants with the skin or the body. In this context, protective clothing of this type, as can be present, for example, in the form of protective suits, protective jackets or the like, often also has a corresponding headgear or hood, for example in the form of a hood or a balaclava.

In general, the purpose of ABC or CBRN protective clothing is to offer the wearer or user optimal protection against poisonous or warfare agents (hazardous substances, warfare agents or the like), to the effect that the user of such Protective clothing, on the one hand, is protected as well as possible and, on the other hand, can continue to carry out its activities as unhindered as possible. In general, any hazard scenarios in which exposure to poisonous or pollutants can occur can be seen in military conflicts, terrorist attacks that are in a permanent state of change, accidents, (natural) disasters, fires or the like become. The frequency of such hazard scenarios, which is associated with the risk of exposure to poisonous or harmful substances and which is associated with the wearing of appropriate protective clothing, continues to increase to, not least because of the increasing number of trouble spots with the risk of a military conflict, terrorist activities or the like.

With regard to the protective clothing on which it is based, it is also necessary that it ensures the best possible (i.e. in particular long-lasting and as broad-spectrum as possible) protection against poisonous or harmful substances, the protective function, for example, against both military agents and industrial hazards, such as toxic industrial chemicals (TICs) must be guaranteed. It is also of great importance that what is to be used

Overall system, which can include, for example, protective clothing and a breathing mask, in its entirety provides a high protective function, and in this context also the formation of

Weak points or breakthroughs, for example at the respective transition or contact points of the corresponding parts of a protective system, such as the transition area or the interface between a headgear or hood and a respirator, should be avoided. A critical factor that contributes to the overall protective performance of a corresponding protective protection system can also be seen in the transition area (contact area) or the interface between a hood, such as a hood or the like, on the one hand and a respirator, in particular a mask body of a respirator, on the other . A less than optimal seal in this one

The transition area between the hood on the one hand and the respiratory mask on the other hand can lead to poisonous or pollutants getting through the insufficiently sealed transition under the hood and thus to the body or on the skin of a user, so that a related contamination is present and the user with comes into contact with these toxins or pollutants. As a result, gaseous or liquid toxins or pollutants, such as chemical pollutants or military warfare agents or the like, can come into contact with the unprotected skin of a user, which can result in undesirable and even irreversible injuries or even death of the user that such exposure must be avoided at all costs. Against this background, there is therefore a great need in the prior art to provide technical approaches for effectively sealing the transition area of protective clothing, in particular in the form of headgear, such as a hood or the like, on the one hand and a respirator, in particular a mask body of a respirator, on the other.

In this light, there is also a great need in the prior art to provide appropriate protective clothing, in particular in the form of hoods or the like, which have a high adaptability or universality with regard to the underlying respiratory protection masks, which are available in a large variety of models and types. The sealing adaptation or the sealing application of a hood, such as a hood, which can also be part of protective clothing, to a respirator or to a mask body on which the respirator is based is therefore difficult to design that a large number of different types or models of Respiratory masks are present, which can differ from one another with regard to their size or shape or their constructional structure, specifically also with regard to the underlying mask body of the respective respiratory masks. In this context, for example, different concave or convex areas can be present in the respective mask body, wherein the mask bodies can also have different circumferences or dimensions, which is a great challenge for the provision of appropriate protective clothing or hood with a wide range of uses in relation to the Represents a large number of underlying respiratory protection mask types and models.

However, the approaches known in the prior art do not always lead to an optimal seal against corresponding respiratory masks. In addition, there is only a limited adaptability with regard to different types of respiratory protection masks with different physical training or

The mask body is also shaped, so that the range of uses of such a hood is sometimes restricted.

DE 103 27 994 A1 and the documents belonging to the same patent family according to EP 1 628 713 A1, US 2006/117470 A1 and the

WO 2004/105880 A1 relate to a hood which has a circumferential elastic hem which delimits an opening in the field of vision that is used for Admission of a respiratory mask is provided, the hem being intended to lie against the respiratory mask in the application or wearing state. In this regard, a circumferential seal is provided, which is arranged on the inside of the seam pointing into the field of view opening and is intended to rest against a respiratory mask, wherein the seal can be designed as a sealing ring, sealing lip or sealing projection in order to create a plurality of linear elevations or protrusions. To create increases on the hem. However, such a system does not always lead to an optimally sealing fit on a protective mask, in particular with regard to use for different types or models of respiratory protective masks.

Alternative sealing concepts of the state of the art (such as DE 102012 007 502 A1 and DE 10 2014 106 193 A1) are also largely adapted to special respiratory mask concepts and cannot be easily transferred to other types of respiratory mask systems or cannot be used universally.

Against this background, the present invention is therefore based on the object of providing an efficient concept for providing a seal for the transition or contact area of a hood, which is designed, for example, in the form of a hood and / or balaclava, and a protective mask, in particular a mask body of a protective mask to provide, the disadvantages of the prior art outlined above should be at least largely avoided or at least mitigated.

In this context, an object of the present invention in particular is to provide a hood in particular which is used or used for, in or as protective clothing, in particular NBC protective clothing (CBRN protective clothing), preferably for the civil and / or military sector Can be used, which has improved sealing properties in the area of the transition between the hood on the one hand and the respiratory mask on the other hand, this transition should be at least largely sealed against poisonous or harmful substances, so that an ingress of poisonous or harmful substances through the transition area below the hood is to be prevented from contacting the wearer or user of such a hood in this regard. In addition, a further object of the present invention is to provide a corresponding head hood which has a high adaptability or universality with regard to the underlying respiratory protection masks, the head hood for a variety of different respiratory protection mask types or models with different physical shapes sealing connection of the transition area should be used. Thus, within the scope of the present invention, a hood that can be used universally and independently of the type of respiratory protection mask on which it is based is to be provided.

Yet another object of the present invention is to provide a corresponding head hood which is improved in its handling and which enables quick and uncomplicated putting on or pulling on with a simple provision of a sealing contact or a sealing connection with respect to a breathing mask should.

Another further object of the present invention is also to be seen in the fact that the hood as such is to be used universally in such a way that it can be provided on the one hand in numerous designs or forms, in particular as a hood or balaclava, the hood also to the effect that it should have a wide range of application, for example, as such or else as a fixed or detachable component of protective clothing, such as a protective suit or a protective jacket, or should be able to be used.

To solve the problem described above, the present invention thus proposes - according to a first aspect of the present invention - the head hood (hood) according to the invention, in particular in the form of a hood or balaclava, preferably for protective clothing, in particular NBC protective clothing, preferably for the civilian or military area, according to claim 1 before; Further advantageous developments and refinements of this aspect of the invention are the subject matter of the corresponding subclaims relating to the hood according to the invention.

For the purpose of illustrating the present invention, the following description of the subject matter according to the invention is also referred to in the figures; the citing of the reference symbols in this regard is purely illustrative and does not entail any restriction of the subject matter according to the invention.

Having said that, the present invention is described in more detail below. The subject matter of the present invention is thus - according to a first aspect of the present invention - a head hood (also referred to synonymously as a hood), in particular in the form of a hood or balaclava, preferably for

Protective clothing, in particular NBC protective clothing (CBRN protective clothing), preferably for the civil and / or military sector, the hood having a hood body (main section) for head covering and a field of view opening for receiving and covering the edge

Has a respirator, the hood in the area of the

Field of view opening also has:

- A preferably elastic and / or reversibly stretchable sealing element for preferably sealing application to the respiratory protection mask, wherein the sealing element is arranged and / or provided circumferentially in the edge region of the visual field opening and / or wherein the sealing element delimits the head cap circumferentially at the edge from the visual field opening, the sealing element, In particular, the surface (sealing surface) of the sealing element that rests on the respiratory protection mask when it is worn and / or in use is at least essentially flat, in particular in the form of a band or strip, and / or wherein the sealing element, in particular the one on, in the state of wear and / or in use The face (sealing surface) of the sealing element lying against the respirator, at least essentially flat, in particular in the form of a band or strip, rests against the respiratory mask or is formed adjacent, and one of the sealing element on the outside (on the side) and / or on its side facing away from the field of view opening z around at least partially overlapping and / or overlapping edge section, wherein the edge section is provided with a tension element and / or wherein the edge section is assigned a tension element so that the edge section is designed to counteract from the outside and / or the outside and / or in the direction of the field of view opening to press and / or tension the sealing element, in particular in order to thereby press and / or apply the sealing element to the respiratory protection mask when it is worn and / or in use. A central idea of the present invention is thus to be seen in particular in providing a hood with a special design of the area delimiting the field of vision opening, according to which namely a special sealing element on the one hand and, so to speak, with a related pulling element variably adjustable edge section on the other hand with regard to an effective sealing of the transition area or the interface to a respiratory protection mask, in particular a mask protection body of a

Respirator, interaction.

According to the invention, the situation is such that in the state of wear or use the sealing element rests on the respiratory protection mask or on the mask body of the respiratory protection mask on the edge, in particular circumferentially along the field of view opening, with the edge section with the variably adjustable tension element providing an additional force effect or a further pressing of the sealing element onto the respirator or the mask body of a respirator is brought about or effected, so that according to the invention overall an efficient sealing of the transition between the hood (namely in the edge region of the hood to the visual field opening) and a breathing mask, in particular a mask body

Respirator, is guaranteed. According to the invention, it behaves in particular in such a way that the sealing element lying on the edge of the respirator lies, so to speak, through the individually adjustable edge section with the relevant tension element with greater (contact) pressure on the respirator or the related mask body or clamped onto the respirator with greater force becomes.

In the context of the present invention, a high degree of adaptability or universality of the provided head hood with regard to the accommodation or sealing of a large number of different types of respiratory protection masks is ensured, which differ with regard to their shape or construction, in particular also with regard to the design of the respective mask body differ from one another, with a high degree of variability in this regard. Thus, the hood according to the invention can be used for a large number of respiratory masks customary on the market.

Furthermore, according to the invention, a simple handling or improved usability of the head hood according to the invention is ensured, since it can be put on or put on in a simple manner and ensures easy handling with regard to the adjustment or actuation of the tension element of the edge section so that the hood can be attached quickly and easily in the area of the field of view opening an underlying mask body can be adapted or applied in a sealing manner.

In addition, the sealing connection provided between the head hood on the one hand and the respiratory mask or mask body on the other hand is non-slip, so that even under conditions of use that are associated with increased body activity or with increased movement of the mesh wearer (wearer), a secure and permanent fit or wear. a secure seal against a respirator is guaranteed.

As a result, the hood provided according to the invention thus offers a further improved protection of the transition to a respiratory protection mask with at the same time improved manageability or use of the hood as such.

In addition, the hood according to the invention can also be individually designed as such or tailored or individually adapted against the background of the respective purpose of use or application and in this case be present, for example, as a hood or balaclava. The hood according to the invention can be designed or used as independent protective clothing or as a fixed or detachable component of protective clothing, for example as a hood or balaclava as such or as a particularly firmly integrated hood of a protective jacket of a protective suit or the like, as described below .

In the context of the present invention, it is in particular such that the edge section with the corresponding tension element is arranged on the outside or above the sealing element, based on a respiratory protection mask arranged under the sealing element when the hood is worn or in use, and in particular preferably circumferentially along the edge region to the field of view opening of the head hood, the sealing element in turn in particular resting directly or directly on an edge region of the respiratory protection mask or the corresponding mask body. According to the invention, it is thus in particular that the edge section with the pulling element is positioned on the side of the sealing element facing away from the respiratory protection mask and / or the field of view opening when it is worn or in use.

Via the tension element integrated into the edge section, the circumference or the length of the edge section can be reduced or adjusted, so to speak, so that the edge section with the tension element is pressed onto the sealing element, which in turn means that the sealing element is reinforced against the respiratory mask or The mask body is pressed or stretched, namely evenly along or circumferentially to the opening of the field of view.

Overall, according to the invention, an efficient peripheral sealing of a respiratory mask or a related respiratory mask body is thus made possible, specifically with a high degree of individual adaptability or adaptation in relation to different types of respiratory masks.

According to the invention, it also behaves in such a way that the region of the edge section that at least partially covers or overlaps the sealing element from above or from the outside can be positioned freely or unconnected with the relevant tension element on the sealing element. According to the invention, this is made possible in particular by the fact that the edge section with the pulling element on the one hand and the sealing element on the other hand are, so to speak, each designed independently, which means that when the edge section with the pulling element is adjusted accordingly and the associated circumference or length reduction of the edge section, there is a shift of the sealing element with respect to the respirator to be sealed or the mask body is avoided. The edge area with the tension element on the one hand and the sealing element on the other hand are therefore to a certain extent structurally independent systems insofar as the tension element is received by the edge area and, as such, is not in direct contact with the sealing element explained below, in particular is present in a special cavity or tunnel of the edge section and is thus integrated into the edge section. As a result, the tension element does not rub directly in the edge section when it is actuated or displaced on the sealing element, which counteracts the formation of folds in the sealing element with the possible creation of breakthroughs in the transition area to the respirator. Due to the special construction according to the invention, the edge section with the tension element on the one hand and the sealing element on the other hand cooperate functionally insofar as the

Sealing element is pressed further onto the respiratory mask by the edge section as a result of the actuation of the tension element or is applied to the respiratory mask with additional pressure. By guiding the tension element separately in the edge section while avoiding direct contact between tension element on the one hand and sealing element on the other hand, wrinkles or damage or excessive stress on the sealing element are avoided.

According to the invention, a preferably sealing and non-slip contact of the sealing element in the edge region of a

Breathing protection mask or a mask body enables the penetration of poisonous or harmful substances through the transition area between the head hood on the one hand and the breathing mask on the other hand is effectively reduced or prevented, which consequently leads to a further improvement in the protective function of the underlying hood or related protective clothing as a whole leads.

The term "sealing" or "sealing", as used according to the invention in particular with regard to the transition area or the interface between the head hood on the one hand and the edge area of a respirator or a mask body on the other, is to be understood very broadly in the context of the present invention and relates in particular to the prevention or at least to the sustained reduction in the entry or penetration of gases, vapors, aerosols or liquids, in particular poisonous or harmful substances (hazardous substances, warfare agents or the like) in the transition area or interface area between the hood on the one hand and a respirator on the other.

Furthermore, the term “hood”, as used according to the invention, is to be understood very broadly. In particular, the term in question relates to such headgear or designs of the head hood which at least partially cover the head when it is worn or used, whereby if appropriate, the neck can also be covered and, if appropriate, also partial coverage of the shoulders and, if appropriate, the upper back and / or the upper chest area. The term “balaklava”, as used according to the invention, is also to be understood very broadly. A balaclava (synonymously also referred to as a “balaclava”, “balaclava”, “hat” or the like) is designed in particular in such a way that it covers at least substantially the entire head and the neck or neck when it is worn or in use, whereby the face is left free or not covered.

In general, according to the invention it also behaves in such a way that the hood according to the invention has a circumferential edge area to form a field of view opening through which parts or sections (areas) of the respiratory protection mask protrude, so to speak, in the wearing or application state, in particular is the corresponding edge area of a mask body on which a respiratory protection mask is based. The edge area, which according to the invention is formed in particular by the sealing element and the edge section with the related pulling element, should lie sealingly against the respiratory protection mask or the mask body when it is worn or in use.

Another object of the present invention - according to a further aspect of the present invention - is the use of the hood according to the invention, as defined above, in, for or as protective clothing or as a component or part of protective clothing, in particular NBC protective clothing (CBRN protective clothing) , preferably for the civil and / or military sector.

Further refinements, modifications, variations, modifications, special features and advantages of the present invention can be readily recognized and implemented by those skilled in the art when reading the description, without departing from the scope of the present invention.

The present invention is described and illustrated in more detail below, also on the basis of the following exemplary embodiments, which, however, are in no way intended to restrict the present invention. In the following, reference is also made to the embodiments and aspects described above as well as to further configurations of the present invention:

As already mentioned above, one goal of NBC protective clothing is to offer a wearer or user optimal protection against hazardous substances, so that the user on the one hand can carry out his activities unhindered and on the other hand is protected as well as possible. Possible hazard scenarios can arise from accidents, terrorist attacks or armed military conflicts that are in a constant state of change. The frequency of dangerous situations occurring worldwide, in which gaseous or liquid chemical pollutants come into contact with the unprotected skin of people in the danger area and can thus cause unwanted irreversible injuries or even death of these people, is increasing. Therefore, wearing appropriate protective equipment, in particular in the form of protective clothing and a breathing mask, is indicated or necessary for such dangerous situations. In this context, protection against military agents and industrial hazards, in which toxic industrial chemicals (TICs) are released, is of growing importance; such protection can also be ensured within the scope of the present invention.

A critical factor that contributes to the protective performance of the protective system are the interfaces that represent the contact areas between the protective clothing and in particular the corresponding hem and the additional protective devices that cover the remaining body regions such as feet, hands and head / face. In relation to the entire protective suit, the interfaces are particularly in the area of the pants ends and the Foot protection, jacket and pants, sleeves and hand protection and head and breath protection are located. In the context of the present invention, a focus is placed in particular on the particularly critical point or the transition area between a hood or head protection and a respiratory protection mask. The hood or the head protection, as this (r) is provided here, can, for. B. as an integrated hood of a jacket or a protective suit and z. B. also exist as a separate balaclava-like hood. The adaptation of the hood to the mask body or body is a further special challenge due to the large number of available respiratory protective device models with their numerous different shapes, such as concave and convex zones, as well as different circumferences, although this is also possible within the scope of the present invention.

One focus of the present invention is therefore also to be seen in the development and provision of an improved (head) hood / breathing apparatus interface design, in particular for NBC or CBRN protective clothing. According to the invention, protective clothing is also provided which fits the wearing concept of numerous application requirements or user requirements. According to the invention, important aspects, such as ergonomic and thermal load-bearing capacity and a high level of protection, are also coordinated with one another against the background of the respective special application or use needs or requirements.

According to the invention, an ABC or CBRN protective hood with ergonomic properties is provided, which on the one hand can be used for all respiratory mask types relevant to the market and on the other hand provides increased protective performance.

The present invention thus makes it possible to provide an interface solution between the head hood and the respiratory protective device or mask, which prevents the entry or passage of gaseous or liquid pollutants. In the following, critical or disadvantageous aspects of existing hood designs of the prior art relating to head protection on the one hand and the new variants according to the invention with the associated advantages on the other hand are described.

The evaluation and assessment of the hoods according to the invention with the new designs in this regard are then described. The evaluation approach consists in particular in letting a suitably qualified and experienced person (SQEP) exercise the movement protocol as defined in the NATO standard AEP-38 in the 2012 version. The second step is the evaluation after the neck / head system test in a test chamber with volunteers. The results of these tests are described and discussed below. The solution according to the invention, according to which the challenges or problems in the combination of respiratory protection mask and head hood have been solved in a surprising manner, is also illustrated by the following explanations on the structure or design of respiratory protective devices or respiratory masks on the one hand and the head hood provided according to the invention on the other. With regard to the respiratory protective device or the respiratory protection mask, the structure or design of the mask is important, since this or this has a decisive influence on the achievement of a safe and narrow interface. In particular, the following aspects are also of relevance: the shape of the breathing mask on which the hood is to be placed; the areas of the buckles which, for example, hold an optionally provided hairnet; the chin area as well as the mask size. With regard to the aforementioned aspects, an efficient solution is provided within the scope of the present invention with an efficient and safe sealing of the transition area between the head hood and the respirator, along with a high degree of adaptability to the underlying mask type, so that a large number of different types of respiratory masks with the inventive Solution in terms of high sealing of the interface can be detected. The following are examples of market-relevant respiratory masks, each of which has different sizes and shapes, also with regard to the relevant aspects mentioned above: The Avon C50 and FM53 respirators, the Dräger M2000 respirator, the Scott GSR respirator and the M40 US respirator. The size and shape of the various models was taken into account to some extent in the design of hoods in the prior art, but the prior art sometimes encountered difficulties with leaks. The respective mask types have z. B. certain circumferences of the mask body and corresponding lengths of the (fixation) rubber bands used in each case.

The Avon C50 and FM53 respirators have a relatively large circumference in size M. In addition, the sides of the breathing apparatus are adapted to the curve of the face and are therefore very concise in their shape. A rubber band can be attached to the bib-like chin part of the C50 more easily than to the FM53 with its very short chin part, which can also deform, which can lead to wrinkles under pressure.

The side buckles, the relatively short chin section of the FM53 and the curved sides of the C50, for example, can be cited as critical points which can make it more difficult for a hood to fit tightly.

The Dräger M2000 mask, on the other hand, has a relatively small circumference for all sizes. This mask has a rather narrow shape, but less pronounced bulges than the Avon masks (C50 and FM53). A relevant area of the M2000 mask is its chin area, which is designed to be relatively short, which can sometimes lead to an increased probability that a headgear seal lying on it will slip or slip off when the user moves.

The scope of the Scott GSR mask is relatively large for all sizes. This model has a protruding butyl lip that runs over the entire lower part of the mask. Such a lip can reduce the risk of a headgear seal lying thereon slipping when the user moves, but it can sometimes happen that a seal lying on it Seal is raised so that leaks may occur.

In the case of the aforementioned respiratory masks, too, the hood according to the invention shows excellent properties with regard to sealing, adaptation and attachment (prevention of slipping).

With the hood according to the invention, the problems of headgear of the prior art are overcome, which are associated with different sizes of protective clothing, and in particular what related hood or balaclava cutouts or openings, closures of the hood opening or the hood edge or a related field of view opening is concerned. In particular, the hood according to the invention can be used in a uniform size or design for a large number of items of protective clothing.

In the prior art, for example, the closure or the possibility of opening corresponding head hoods, in particular from the collarbone to the hood cutout or to the field of view opening, is problematic. Another problematic point in the prior art is the design of the hood edge for opening the field of view, according to which there are sometimes very simple constructions using, for example, rubber bands as such. However, these rubber bands sometimes do not compensate for the concave areas of the aforementioned Avon masks, since the rubber band around the mask may not be able to fill or seal the curves of the mask, so that leaks occur and pollutants can penetrate. This problem has also been overcome according to the invention. In order to further address the problem of concavity, in the context of the present invention, in addition to the special combination or formation of the seam or edge area for the field of view opening, namely on the basis of the sealing element on the one hand and a special edge section with tension element on the other hand, the sealing element can be additionally attached to the Mask bodies are pressed by sealing elements, in particular in the form of cushions or pads, such as gel or air cushions or the like, so that, for example, the lateral shaped areas of a breathing mask, in particular of the aforementioned type, continue to be sealed again. The cushions, which have a defined size and shape, can be sewn into the hood, for example, into an annular, stretchable filter material (for example in the form of the further inner material). The possibly provided cushions can be in the worn and / or used state, in particular at the level of the ears or cheeks of the user, in particular at least essentially directly on the border to the sealing element or elastic band.

The above-mentioned flexible filter material or the textile materials forming the hood, also with regard to the possibly provided additional and in particular annular inner material with undersize, also enable greater elasticity and thus further support of the sealing element or elastic band. The inventive concept with the combination and interaction of the sealing element and the edge section with the tension element also counteracts any undesired lifting of any cushions that may be present, for example in the area of the buckles of a respirator, which in particular run along the user's ears.

The present invention also overcomes disadvantages of the prior art, which are associated, for example, with the use of very wide rubber rings (butyl rings) with a narrow ring shape or narrow inner opening as such, as used as sealing bodies. Such a concept of the prior art is associated with a certain, but not always optimal, seal, but due to the closed and narrow ring shape it is sometimes very difficult for a user to pull a balaclava equipped with it over his head with the breathing apparatus on. One of the last pieces of equipment that the user takes off during decontamination is the breathing apparatus. It is therefore only possible to cut open such a (storm) hood and the closure. Failure to do so could cause the respirator to come out of position while attempting to remove the hood. This disadvantage is also not present according to the invention. In general, with regard to the present invention, it can also be such that varying sizes of an underlying protective clothing, such as a protective suit or a protective jacket, do not influence the hood size and / or the hood cut, so that according to the invention a universal cut for a variety of protective clothing is provided, as also stated previously.

A uniform outer fabric and a uniform filter material were used for the hoods according to the invention and the related designs, since this makes it easier to compare the designs and the models are not influenced by different materials. In particular, special processing was used. An outer jacket material and a filter material were selected for this. Established combinations and materials were used in the area of surface materials. These materials are tested and established and used in standard one-piece and two-piece designs.

For the solutions, it is advantageous if material combinations are selected that can be used for all designs in terms of processing and at the same time are equipped with a chemical protective property. Comparability should also be ensured, which is the reason why the same material combination was used for the aforementioned respiratory mask models. The outer fabric was flame resistant and oil and water repellent. The cotton fabric was woven in a twill weave. The diagonal body ridge in the Z direction is characteristic. In this weave, the connection points are laterally offset and arranged adjacent to one another. This twill weave is very tightly woven and has good mechanical strength and durability. The fabric has a soft feel. In particular, it is a standard upper material that is used in the area of NBC or CBRN protective clothing and takes air permeability into account to support the adsorptive performance of the filter material. The textile filter material used for the respective hoods was a multi-layer laminate. The inner component consists of 88% cotton and 12% elastane and is a knitted fabric. This is followed by an adsorption layer and a carrier material or a carrier layer consisting of 100% polyamide, also as a knitted fabric. The hoods listed in the context of the present invention on the basis of the present exemplary embodiments and the relevant designs have been produced with this filter material.

Overall protection systems, such as jackets, pants and full-body protective suits, cannot generally be designed on the basis of a filter material as such. The design solutions consist of the above-mentioned outer fabric and the woven basic filter material.

With regard to the hood according to the invention, the evaluation also plays a very important role in determining whether the product according to the invention meets the respective requirements, for example also whether it is safe and comfortable with regard to the granting of freedom of movement and whether it is a allows the user to carry out the task unhindered. The evaluation of the presented design solutions took place in two stages: First, exercises were carried out according to the AEP-38 movement protocol in order to verify the good and reliable fit of the hood / mask interface. In addition, a test of the entire system was carried out in a test chamber environment with a simulant. In particular, the investigations relate to exercises with the aforementioned breathing masks and hoods according to the invention.

During the entire run through all exercises with the corresponding respiratory protection masks and hood designs, the hood edges with the elastic band and the drawstring remained unchanged on the masks.

The tests and investigations were carried out in accordance with the procedures and requirements as also listed below. For the test runs, several hoods according to the invention were tested on different types of respiratory protection mask. The selection of the designs tested was made depending on the size of the two volunteers. After the subject For the test run in the form of a fixation of specially prepared samplers or sensors (PADs) on the head and upper body as well as the swallowing of a special sensor that monitors the state of health, the test subjects were equipped as listed in Table 1 below.

Table 1

The results show the protection factor and the protective properties of the evaluated hood models with the corresponding respiratory protective devices and the arrangement of the samplers (PADs). Table 2 shows the test results of Run 1.

Table 2

If the protection factor has a value of 1, it means that the simulant (methyl salicylate, MeS) has penetrated the entire sampler (PAD) (so that the simulant could pass through the suit at an open point). If the protection factor has a value greater than 100, this means that the sampler or the pad was exposed to MeS, but to such an extent that the user would not be in danger of death.

In summary, it can be stated that the concept according to the invention can be used for the mask type and that significantly improved protective properties are present or result on this basis. Table 3 shows the test results of runs 2 and 3 with the hoods according to the invention with zipper and the balaclavas according to the invention. The first two columns from the left show that all samplers (PADs) are working and that the protective properties are overall comparable.

Table 3

The balaclava or balaclava according to the invention with the FM53 respirator shows a very high average protection factor, especially since there is no closure in the balaclava. The other models also have good protective properties.

It can thus be shown overall that the present invention is accompanied by a significant improvement in the protective properties of the inventive head hood or balaklava, in particular in connection with the universal applicability, which was not given in the prior art.

The development and evaluation of an improved hood / respirator interface design for ABC or CBRN protective clothing that seals the transition area in question over the long term is aimed at an underestimated element of protective suits for human life in hazardous situations. In the present case, the given requirements with regard to the development of mask-specific solutions were focused, which result in a higher or more constant protection as well as a simplified and quick donning and doffing process (donning and doffing). In addition, according to the invention, the problem of incorporating a Velcro fastener in the hood end region could also be solved by developing a zip fastener up to the hood edge. This led to positive test results. Consequently, the question of whether it is possible to provide ABC or CBRN protective hoods with ergonomic properties, which on the one hand can be used for all respiratory mask types relevant to the market and on the other hand, offer increased protective performance, can be positive within the scope of the present invention Statement to be answered. The following components characterize the best-functioning interface solutions, namely on the basis of a sealing element and an edge section with a tension element (in particular with a cord tunnel), with any closures or opening elements that may also be present without permanently reducing the protective performance. Based on the tests or examinations with the appropriate, qualified and experienced person (SQEP), it was found that the entire hood solution remains in position and does not slip off the mask. Chemical tests show that the hood according to the invention with a zipper with the M40 respiratory protection mask gives the best results, the other masks according to the invention also giving very high values for the protection factor. According to the invention, it is also ensured overall that the pressure of the cord tunnel pull presses the sealing element decisively onto the mask and does not deform the mask body or body in the process.

The need for safe head protection and an easier and faster donning and doffing process is constantly increasing. This development is therefore important for providers and users of protective equipment as a whole. The present invention also provides a corresponding solution for this.

In addition, it is important that the design of the head and respiratory protection are matched to one another in order to provide an improved protective performance of the entire protective system, which is equally guaranteed according to the invention.

Overall, very high protection values are obtained for the designs according to the invention or for the hoods according to the invention.

Further information on the underlying experimental setup is given below:

In the present case, a defined test set-up or procedure was chosen to investigate the protective performance or to test the items of clothing in order to reduce complexity and to ensure standardization.

The following can be carried out for testing at the material level:

Materials used for chemical and biological protection can be tested using specified material tests. These were developed to protect the user from life-threatening chemicals. The chemical safety test includes a "laid drop" test, in which the surface of a test specimen mounted in test cells is gentle is covered with droplets of a hazardous substance simulant, so that the hazardous substance accumulates over time through permeation processes. A contamination density of 10 g / m ² in the form of 1 pL droplets is often chosen in a 24-hour test. Miniaturized chemical drug monitors can be used to monitor the permeation of drug vapor. The liquid permeation is typically given in pg / cm ² , the vapor permeation in doses. This corresponds to the average breakthrough concentration multiplied by the duration and is given in mg * min / m ³ .

The test for toxic industrial chemicals (TIC) includes testing according to the EN / ISO test method. It measures the permeation of toxic chemicals used in industry. TIC testing is as rigorous as the war chemical testing safety protocols, and similar testing precautions are in place, as TICs, in adequate doses, can be just as lethal as chemical warfare agents (CWAs).

In addition, the following can be carried out for testing at the system level or the overall system:

The "man-in-simulanf'-Jesi" (MIST) is the primary method used by the military to assess clothing ensembles for protection against chemical and biological warfare agents. The MIS test has been included in the current editions of the National Fire Protection Association (NFPA The ASTM has developed a new test method (ASTM F 2588-06) for the assessment of protective ensembles according to MIST. Other relevant test methods are described in the standards of the International Organization for Standardization (ISO). The main differences between the test methods lie in the choice of the effective test substance (e.g. sulfur hexafluoride, methyl salicylate) and the training protocol for the test subjects. In addition, there are also tests with actual hazardous substances in which a mobile dummy equipped with sampling devices and protective clothing is placed in the test chamber. The aim of the overall system test (WST), as it was carried out with the present design models or hoods, is to determine the level of protection of a (complete) protective suit ensemble. A certain concentration of the non-toxic compound methyl salicylate (MeS) was used in vapor form as an irritant or simulant for toxic warfare agents (mustard gas). The volunteer test person (test subject) was equipped with passively adsorbing samplers (PADs), which are applied to the skin, with the volunteer wearing complete protective equipment as part of the test. Over a defined period of time, the test subject carried out a standard movement protocol in the test chamber, the air of which was loaded with a certain MeS vapor concentration. The MeS, which could possibly penetrate the suit material or get into the suit through openings, was adsorbed on the PADs and then analyzed. The breakthrough doses measured on the various body regions and the local protective factors that can be calculated from them were output. For safety reasons, the test subjects are equipped with a core temperature and heart rate monitor during the tests, whereby the data obtained from them can also be used to obtain an indication of the thermal stress caused by the suit during the test. The test chamber consisted of a wind tunnel with a length of 18 m and with a closed circuit. The test chamber had 9 fans, arranged in 3 rows of 3 fans each. The chamber temperature could be set between 15 ° C and 35 ° C. MeS was used as an irritant or simulant. The steam was generated in a controlled evaporator mixer behind the exposure area so that the entire length of the tunnel could be used to mix the steam with the test room atmosphere. The concentration was continuously and simultaneously monitored by a gas chromatograph with a flame ionization detector. While the concentration was being built up or the chamber was being flushed, the subject was not present in the chamber.

The penetrated or penetrated MeS vapor was determined by passive adsorption using passive samplers (PADs), which consisted of an impermeable polymer carrier and a polyethylene top layer. The two layers are heat sealed together so that they form a kind of pocket which is filled with 80 mg Tenax TA 60/80 mesh. The methyl salicylate (MeS) penetrates the polyethylene layer at a certain speed and is adsorbed by the Tenax. The uptake rate of the PADs was measured in a separate PAD determination at low concentrations of MeS. The amount of MeS adsorbed on the samplers was analyzed by means of thermal desorption and gas chromatography. The amount on the passive sampler was converted into the penetrated dose, expressed in ml / min, using the uptake rate of the sampler. The measured penetration doses were standardized to the specified stimulus dose, expressed in mg * min / m ³ , especially since the actual test conditions (concentration and exact duration) can sometimes deviate slightly from the desired settings.

The test results were reported as the protection factor provided by the garment at a specific location on the body. The protection factors were also determined on the basis of the standardized penetration dose.

The sampler pattern defined in AEP-38 in the 2012 version was used, ie some additional samplers were placed compared to the original ASTM F2588 sampler pattern. The movement protocol was carried out in accordance with AEP-38 in the 2012 version as follows: a) Movement of weights: Two 2.5 kg weights are repeatedly lifted from a shelf (at waist height) and placed on the floor. Then a standing position is taken. The weights are picked up again and put back on the shelf. The right side of the test person is aligned in the direction of the wind. b) Sitting (facing the wind). c) Jumping Jacks: A jumping jack is performed about every 2 seconds, and every few seconds the test person changes his position so that another section of his body is facing the wind. d) Sitting (facing the wind). e) Walking on a treadmill: The participant walks at a speed of 1.3 to 1.8 m / s in the direction of the wind. f) Sitting (facing the wind). g) Climbing a ladder: The subject repeatedly climbs 2 to 3 steps up a step ladder and touches the ceiling of the test chamber (hands alternating), then descends back to the floor and crouches down to touch the floor with both hands. The test person is oriented with his back to the wind. h) Sitting (with his back to the wind): The participant looks from side to side every 15 seconds, then at the ceiling and floor. Each activity was performed twice over an hour for 3.75 minutes.

The above statements thus make clear overall the special advantages and properties of the head hood according to the invention, specifically also with regard to its universal applicability for a large number of mask types while providing a sealed transition to a respective respiratory mask.
