Abstract

The present invention relates to protective clothing with a protective function against chemical, biological or radioactive pollutants and / or toxic substances, preferably for civil or military purposes.

Description

[0001] The present invention relates to the technical field of ABC protection or CBRN protection and in particular to the technical field of protective clothing with a protective function against chemical and / or biological and / or radioactive pollutants or toxic substances (such as hazardous substances, warfare agents or the like), as it can be used in particular in the military and civilian sectors.

[0002] In particular, the present invention specifically relates to NBC protective clothing or CBRN protective clothing (with ABC = atomic, biological, and chemical and, synonymously, with CBRN = chemical, biological, radioactive, and nuclear; the terms ABC and CBRN are used synonymously within the scope of the present invention). In this context, the present invention thus also relates to the technical field of corresponding NBC or CBRN protective clothing, as it can be used in particular for military purposes and also for civilian purposes (for example, in the field of hazard prevention, firefighting, disaster control, or the like).

[0003] Against this background, the present invention relates in particular to protective clothing with a protective function against chemical or biological or radioactive pollutants or toxins (ie chemical pollutants and / or toxins, biological pollutants and / or toxins and / or radioactive pollutants and / or toxins), such as warfare agents, wherein the protective clothing according to the invention has at least one extremity section for, in particular, partial and / or complete protection of at least one extremity of a wearer of the protective clothing, preferably in the wearing and / or use state.

[0004] The present invention further relates to a method for producing protective clothing with a protective function against chemical or biological or radioactive pollutants or toxins (ie chemical pollutants and / or toxins, biological pollutants and / or toxins and / or radioactive pollutants and / or toxins), such as warfare agents.

[0005] Likewise, the present invention also relates to the use of a widening section for improving the wearing comfort and / or for improving the donning behavior and / or the putting on and / or the adaptability (i.e. adaptability to a user or wearer or in the worn state) of protective clothing with a protective function against chemical and / or biological and / or radioactive pollutants and / or toxic substances (warfare agents) ("ABC or CBRN protective function"), in particular ABC protective clothing ("CBRN protective clothing"), preferably for civil or military purposes, in particular in the form of trousers, a jacket or an overall, preferably in the form of trousers.

[0006] Pollutants and toxic substances generally pose a high level of danger, and can have a detrimental effect on the health of those who come into contact with them. Exposure to or contact with them, for example through contact with skin or mucous membranes, inhalation, ingestion, or the like, must therefore be avoided or at least minimized. This is particularly important given that the health impairments and toxic potential of such substances can sometimes be considerable, and that contact with or ingestion of even small amounts of such substances can lead to long-term health problems and even death in those affected. In this context, it should also be noted that toxic and harmful substances can exist in numerous chemical and physical forms, for example as gases, liquids, or solids, and in the form of finely divided or finely particulate aerosols.of pollutant particles or the like present in the air, especially the ambient air.

[0007] Not least against this background, there is a great need or necessity to provide people who are at risk of coming into contact with toxic or harmful substances, such as soldiers, firefighters, police officers, members of special or special units or the like, with appropriate protective clothing with ABC or CBRN protection function, in order to prevent the absorption of corresponding toxic or harmful substances when deployed in a contaminated or polluted environment by wearing the protective clothing.

[0008] Particularly for groups of people such as soldiers, firefighters, police officers, members of special units, etc., who are at increased risk of coming into contact with toxic or harmful substances, it is particularly advisable and necessary to ensure appropriate protection against these toxic or harmful substances. Often, toxic or harmful substances can be absorbed through the skin as well as the respiratory tract, which represents a high risk potential. Therefore, it is often necessary to have appropriate protective clothing (ABC or CBRN protective clothing) on ​​hand to prevent the toxic or harmful substances from coming into contact with the skin or body. In this context, such protective clothing, which may be in the form of protective suits, jackets, etc., often also includes appropriate headgear orA head covering, for example in the form of a hood or balaclava, is also worn. Such protective clothing, such as protective suits, protective jackets, or the like, is often designed to be compatible with protective devices against the oral intake of harmful substances, for example, in the form of gas masks.

[0009] To improve wearing comfort while simultaneously providing a high level of protection against harmful or toxic substances, air-permeable, permeable protective clothing systems are known in the prior art. These systems can be equipped with an adsorption filter layer, particularly to ensure protection against harmful or toxic substances. Due to the increased exchange of air and water or water vapor, such protective systems offer improved wearing comfort while generally providing good protection against toxic or harmful substances. With such protective clothing, the adsorption material, if used, is sometimes arranged on the side of the material facing the wearer or user when worn, so that any toxic or harmful substances that have previously penetrated the material can be absorbed by the adsorption material.

[0010] In this context, the general purpose of ABC or CBRN protective clothing is to provide the wearer or user with optimal or further protection against harmful or toxic substances, in particular insofar as the wearer or user of such protective clothing is, on the one hand, protected in the best possible way and, on the other hand, can start and carry out his or her operational activities as quickly and time-efficiently as possible, as independently and as unhindered as possible.

[0011] Thus, in addition to providing appropriate protection against poisons and warfare agents, the comfort provided by the protective clothing also plays a major role, both in terms of a good fit and the possibility of donning the protective clothing in an uncomplicated and efficient manner, as well as as autonomously as possible. With regard to the provision of this type of protective clothing, a major challenge lies in providing the most holistic and / or versatile or full-surface and reliable protection possible, whereby protection against a multitude of different poisons and harmful substances that exist in various (physico-chemical) forms must be ensured. The mostly contradictory properties of providing a high level of protection on the one hand and a high level of comfort on the other.in particular a comparatively uncomplicated putting on of the clothing on the other hand should be equally fulfilled in one and the same material.

[0012] With regard to protective clothing, it is also necessary to ensure the most long-lasting and versatile protection possible against toxins and harmful substances. The protective function must also be guaranteed in the event of high local concentrations of harmful substances or toxins (for example, if a drop of a harmful substance or toxin comes into direct contact with the protective clothing) and thus in the event of high local concentrations of harmful substances or toxins. The protective function must also be guaranteed for long periods of time and under adverse operating conditions, including in particularly critical sections or areas of the protective clothing, such as end and transition areas, for example head or neck openings, field of vision openings, abdominal or pelvic openings, but in particular arm or hand openings and leg or foot openings. The same applies to transition or connecting areas between pieces of clothing that are joined together orsimultaneously worn protective clothing, such as between a jacket and trousers, or between a jacket sleeve and a glove, or between a trouser leg and a shoe (or a protective system). Such locations, sections, and transition areas are particularly problematic with regard to providing efficient and permanent protection against the ingress of harmful or toxic substances, on the one hand, and with regard to the most autonomous, independent, and time-efficient donning (and doffing) of protective clothing, on the other.

[0013] To improve donning comfort while simultaneously providing a high level of protection against harmful or toxic substances, state-of-the-art measures (or avoidance strategies) are known, such as the provision of one-piece, oversized protective suits or the provision of devices for the variable adjustment of openings, such as sleeve or trouser leg ends, in transition areas. One-piece protective suits are generally characterized by low levels of comfort or reduced handling, particularly when donning the protective suit quickly, particularly with regard to passing the extremities through the sleeves or trouser legs or inserting the extremities into the sleeves or trouser legs of corresponding protective suits, as well as correctly positioning the protective suit, so that functionality and wearing comfort are often inadequate.Therefore, putting on one-piece protective suits by the user is only possible with increased effort and is not very time-efficient. There is also a risk of damage to the protective clothing by wearing corresponding underwear or protective equipment, such as footwear or gloves. This applies particularly to those sections of the protective clothing that follow the basic body shape of the user, i.e., the sleeves or trouser legs of a protective suit, which usually taper from the origin of the extremity to the end of the extremity, making it difficult to insert footwear or protective underwear.

[0014] Multi-part protective suits typically have the same problem (constricting extremity sections). If extremity sections are not tapered, there is an increased risk of contaminant penetration due to the larger remaining gap. Furthermore, the sealing performance and / or handling of adjustment or closure devices may be inadequate, with a constriction of an extremity section occurring only at very specific points or in a localized manner. A high degree of precision or dexterity is also regularly required when donning the protective clothing, which may not be possible under certain circumstances, for example, due to the wearing of gloves or safety footwear.

[0015] The design of protective clothing therefore moves within a particularly contradictory field of tension: on the one hand, the requirement for protective clothing to be able to be put on quickly, easily, and independently or autonomously, while then providing sufficient comfort, combined with the guarantee of a certain freedom of movement and flexibility for the user. On the other hand, the area of ​​openings in protective clothing for the intake or passage of body parts of a wearer or user represents a particularly critical structure with regard to the unwanted penetration or penetration of harmful or toxic substances. The same applies to the transition area or contact area between different elements of protective clothing, for example a jacket on the one hand and trousers on the other, or a jacket or a sleeve of a jacket on the one hand and a glove on the other, or trousers ora trouser leg on the one hand and a shoe on the other.

[0016] In particular, these transition areas are associated with a corresponding risk of excessive exposure or exposure of a person in the danger zone to the pollutants or toxic substances in question.

[0017] At the same time, these transition areas often present weak points or points of complications when putting on or taking off protective clothing, particularly with regard to a (time-)efficient and autonomously realizable option for putting on and taking off clothing in a simple and time-efficient manner.

[0018] In this area of ​​tension, there is still a great need in the state of the art to provide technical solutions for effective and at the same time comfortable or at least uncomplicated application, particularly with guaranteed sealing of critical transition or connection areas of protective clothing.

[0019] In this context, there is a particular need to protect the corresponding transition area or opening area in protective clothing against the entry or breakthrough or penetration of harmful or toxic substances hitting the material and at the same time to enable the user to put on and take off the protective clothing safely, comfortably and quickly.

[0020] DE 10 2006 032 145 A1 relates to protective clothing with a protective function against chemical and / or biological pollutants, in particular for civil or military purposes, such as ABC protective clothing or the like, wherein the protective clothing has a multi-layer structure or a multi-layer textile construction with an outer material and an inner material equipped with a protective function against chemical and / or biological pollutants, wherein the protective clothing is provided with at least one ventilation opening which is closed with a gas-permeable, in particular air-permeable, protective filter material which sorbs chemical and / or biological pollutants.

[0021] Furthermore, DE 10 2010 004 000 A1 relates to a textile sheet material with improved mechanical stability, in particular with puncture and / or bullet resistance, and with a protective function against chemical and / or biological poisons, in particular warfare agents, wherein the textile sheet material has a multi-layer structure, wherein the layer structure has at least one puncture and / or bullet-resistant layer and at least one adsorption layer based on discrete adsorbent particles.

[0022] Furthermore, DE 20 2023 102 997 U1 relates to a protective and / or filter material with a particle and / or aerosol filter function, wherein the protective and / or filter material is designed as a multi-layer textile composite material having a plurality of interconnected layers and wherein the protective and / or filter material has the following layers, preferably in the sequence mentioned below: (a) a first textile carrier layer, wherein the first textile carrier layer is present and / or designed as a preferably gas-permeable, textile sheet structure;(b) a particle and / or aerosol filter layer associated with the first textile carrier layer, wherein the particle and / or aerosol filter layer is present and / or formed as a gas-permeable textile fabric comprising or being formed from a plurality of individual textile fibers, and wherein the particle and / or aerosol filter layer is formed in multiple layers, wherein the particle and / or aerosol filter layer has at least one outer carrier layer and at least one layer arranged between the outer carrier layers; (c) optionally an adsorption layer associated with the particle and / or aerosol filter layer, wherein the adsorption layer comprises or is formed from a plurality of individual and / or discrete adsorbent particles;

[0023] Furthermore, WO 2024 / 217736 A1 relates to a protective or filter material with a particle or aerosol filter function, wherein the protective and / or filter material has improved regeneration resistance, in particular wash resistance, wherein the protective or filter material is suitable for the production of protective suits as well as filters and filter materials of all kinds; as well as a method for producing this protective or filter material.

[0024] Against this background, the present invention is based on the object of proposing an efficient technical solution for providing protective clothing that can be put on in a time-efficient manner, independently and safely and at the same time can be worn reliably, safely and comfortably, whereby the previously described disadvantages of the prior art are to be at least largely avoided or at least mitigated.

[0025] In this context, a particular object of the present invention is to provide protective clothing which has an ABC protection function (CBRN protection function) and which can preferably be used or employed for the civilian and / or military sector and which has improved sealing properties against harmful or toxic substances in the transition or connection area of ​​a protective clothing, wherein the transition or connection area should on the one hand be sealed against harmful or toxic substances, and on the other hand the transition or connection area or, in a broader sense, the protective clothing as a whole should be designed in such a way that the user can put it on autonomously in a time-efficient, safe and uncomplicated manner and can adjust it safely and comfortably.

[0026] The measures used to solve the underlying problem according to the present invention should be optimized in terms of process and conception and be able to be implemented universally and should also enable the production of corresponding protective clothing on an industrial scale.

[0027] To achieve the above-described object, the present invention thus proposes - according to a first aspect of the present invention - the protective clothing according to the invention with a protective function against chemical or biological or radioactive pollutants and / or poisons (warfare agents), in particular NBC protective clothing, preferably for civil or military purposes, according to patent claim 1; further advantageous developments and refinements of this aspect of the invention are the subject of the corresponding sub- and auxiliary claims relating to the protective clothing according to the invention.

[0036] In particular, for the features characterizing the invention, any combination of these features is deemed to be disclosed, with embodiments of the various features having the same preference in their combination being preferred (e.g., amounts or ranges of amounts of the relevant ingredients of the same preference, or the like). Likewise, all other combinations (i.e., combinations based on different preferences or different levels of preference) are also disclosed.

[0037] With this in mind, the present invention will be described and explained in more detail below, also with reference to drawings or figures showing preferred embodiments or exemplary embodiments.

[0038] The subject matter of the present invention - according to a first aspect of the present invention - is thus protective clothing with a protective function against chemical and / or biological and / or radioactive pollutants and / or poisons (warfare agents) ("ABC or CBRN protective function"), in particular ABC protective clothing ("CBRN protective clothing"), preferably for civil or military purposes, in particular in the form of trousers, a jacket or an overall, preferably in the form of trousers, wherein the protective clothing comprises a multi-layer protective material, wherein the protective material comprises: (a) a first, in particular flat and / or two-dimensional, layer in the form of a multi-layer, in particular at least two-layer, air-permeable adsorption filter material (“inner layer”), in particular for the adsorption of chemical and / or biological and / or radioactive pollutants and / or toxins, preferably wherein the adsorption filter material has an adsorption layer and a textile carrier layer (“adsorption layer carrier”), and (b) a second, in particular flat and / or two-dimensional, layer in the form of a textile, air-permeable outer material (“outer layer”), wherein the protective clothing has a widening section that can be opened and / or closed with at least one closure means for selectively widening and / or enlarging the inner and / or outer diameter of the protective clothing in the region of the widening section, wherein the widening section is arranged at least partially, preferably completely, on and / or in the extremity section, and wherein the closure means is only and / or exclusively connected to the second layer, in particular sewn, and / or wherein the closure means is, preferably directly, unconnected to the first layer, in particular wherein the closure means is connected to the second layer by sewing in at least one seam region, in particular using at least one yarn and / or thread.

[0039] The protective clothing according to the invention thus has at least one extremity section for, in particular, partial and / or complete protection of at least one extremity, in particular at least one upper and / or lower extremity, of a wearer of the protective clothing, preferably in the wearing and / or use state, in particular wherein the extremity section surrounds and / or encloses at least one extremity of the wearer at least in regions.

[0040] In addition, the protective clothing according to the invention comprises a multi-layer protective material. The protective material according to the invention comprises: (a) a first, in particular flat and / or two-dimensional, layer in the form of a multi-layer, in particular at least two-layer, air-permeable adsorption filter material (“inner layer”), in particular for the adsorption of chemical and / or biological and / or radioactive pollutants and / or toxins, preferably wherein the adsorption filter material has an adsorption layer and a textile carrier layer (“adsorption layer carrier”), and (b) a second, in particular flat and / or two-dimensional, layer in the form of a textile, air-permeable outer material (“outer layer”).

[0041] Furthermore, the protective clothing according to the invention has a widening section that can be released and / or closed with at least one closure means for selectively widening and / or enlarging the inner and / or outer diameter of the protective clothing in the region of the widening section, wherein the widening section is arranged at least partially, preferably completely, on and / or in the extremity section.

[0042] Furthermore, the closure means is only and / or exclusively connected to the second layer, in particular sewn, and / or the closure means is, preferably directly, unconnected to the first layer, in particular wherein the closure means is connected to the second layer by sewing in at least one seam area, in particular using at least one yarn and / or thread.

[0043] A central idea of ​​the present invention is therefore to provide a solution that significantly facilitates donning and wearing the protective clothing, while maintaining at least the same, but in particular even improving, protective performance of the protective clothing, in particular with regard to independent, rapid, and inexpensive donning of the protective clothing while simultaneously ensuring the safety of the user. The present inventive concept therefore represents a particularly balanced and, in this respect, user-oriented and application-optimized solution for protective clothing that enables the user to don the protective clothing in a simplified, quick, and safe manner, without any fear of any loss in the protective and safety properties of the protective clothing.

[0044] In this context, it is specifically provided according to the invention that the multi-layer design of the protective material provided within the scope of the present invention, in combination with the targeted arrangement of the at least one closure means on the protective material, namely in particular at least on the second layer and not on the first layer, ideally ensures the safety and protective properties of the protective clothing, while at the same time creating the possibility of putting on the protective clothing more easily, in particular in the event that the user wears extensive underwear, and in particular also of adjusting and adapting it in a cost-effective and targeted manner so that the protective performance of the protective clothing can be optimally realized, i.e. the risk of contamination for the user can be reduced or eliminated as far as possible in a time- and effort-efficient manner.

[0045] According to the invention, the user of the protective clothing according to the invention is reliably able to completely put on the protective clothing autonomously within a comparatively short time, even if the user is wearing safety footwear, gloves or even rubber overshoes, and then to optimally position, adjust or adapt the protective clothing in a short time and with inexpensive (and possibly imprecise) manual actions or measures, in particular so that the protective effect of the protective clothing is reliably realized without impairment.

[0046] In this regard, the applicant has found, in a completely surprising manner, that in a protective clothing comprising a multi-layer protective material and having a widening section which can be opened and / or closed with at least one closure means for selectively widening and / or enlarging the inner and / or outer diameter of the protective clothing in the region of the widening section, wherein the widening section is arranged at least partially, preferably completely, on and / or in the extremity section, and wherein the closure means is only and / or exclusively connected to the second layer, in particular sewn, and / or wherein the closure means is (directly) unconnected to the first layer, in particular wherein the closure means is connected to the second layer by sewing in at least one seam region, in particular using at least one yarn and / or thread,the protective effect of the protective clothing remains unaffected by the widening section or the closure means, in particular since the first layer of the protective material of the protective clothing, designed as an inner layer, is not structurally and accordingly, in particular functionally, influenced by the widening section or the closure element.

[0047] Particularly preferably, the closure means is not sewn to the first layer. Alternatively or additionally, it is preferably provided that the seam connecting the closure means and the second layer to one another and / or the related seam region is unconnected to the first layer. Accordingly, in particular, the first layer is not damaged, perforated, and / or penetrated by the closure means or by the connection of the closure means to the second layer. The protective effect of the protective material can therefore be ensured even with improved positioning of the protective clothing on the wearer's extremities and is not impaired, in particular, by the widened section.

[0048] In this context, it is understood that the feature that the closure means is only and / or exclusively connected to the second layer is to be understood in particular in such a way that the second layer does not comprise the first layer, whereby the second layer can in particular also be constructed in multiple layers. In the case of a multi-layered structure of the second layer, the closure means is particularly preferably only and / or exclusively connected to at least one layer, in particular all layers of the second layer. The second layer is also designed in the form of a textile, air-permeable outer material. This feature is to be designed in particular in such a way that at least one layer of the second layer is textile and air-permeable. Further layers of the second layer can - but in particular do not necessarily have to - be textile and air-permeable.In a multi-layered structure of the second layer, it is particularly preferred that all layers are textile and air-permeable.

[0049] Nevertheless, the protective material as a whole, i.e. both the inner layer and the outer layer of the protective material, can be designed to correspond to the widened section, so that putting on the protective clothing is easier and uncomplicated thanks to the widened section. In particular, the positioning and adjustment of the protective clothing is also made significantly easier and is intuitive and user-friendly thanks to the inventive design of the widened section. This also ensures that the protective properties of the protective clothing according to the invention are optimally realized in that the inner and outer diameters of the protective clothing can be optimally regulated thanks to the flexibly manageable widened section, in particular in a manner tailored to the realization of an optimized protective effect.

[0050] This means that within the scope of the invention, when wearing complete protective equipment, it is still guaranteed that the user can nevertheless adjust the protective clothing according to the invention in a safe and manageable manner, in particular in the extremity section, reliably narrow it by the area of ​​the widening section, so that a reliable sealing effect can be achieved that goes beyond a conventional sealing effect for conventionally designed protective clothing, in particular since within the scope of the present invention, overall inner and outer diameters can also be realized that are usually not practical to implement, without making it considerably more difficult to put on protective clothing, in particular when wearing corresponding underwear or safety shoes or gloves.

[0051] Thus, within the scope of the present invention, designs of protective clothing are also possible that could not previously be implemented due to application-specific limitations, such as the provision of inner and outer diameters for extremity sections, which previously had to be tailored in such a way that users wearing, for example, safety shoes could put on the protective clothing or slide into it with sufficient ease. This regularly results in a comparatively large volume of space between the user's body circumference and the protective clothing, which increases the risk of forming perforations, particularly at transitions or openings in the protective clothing, due to undirected wrinkling caused by excess material in these areas.

[0052] With the present invention, such a risk is significantly minimized by the widening section being able to provide volume in a targeted manner and also compensate for it, depending on the application phase of the protective clothing.

[0053] It should be emphasized as particularly advantageous that the present invention enables a defined, predetermined addition or removal of material surface or clothing volume that is optimized for the user or the intended use, which is particularly beneficial in terms of application safety and simplicity. In particular, within the scope of the present invention, it is no longer left to the user - who may find themselves in an exceptional situation - to find a safe adjustment of the protective clothing that is optimized with regard to achieving a protective effect, but rather the protective clothing itself dictates the degree to which the amount of material or clothing volume is added or, above all, reduced in order to optimally ensure the application safety of the protective clothing. In this sense, the present invention also specifically facilitates the rapid adjustment of the protective clothing.Above all, the probability of application errors when adjusting the clothing is reduced so significantly that the user can be offered more reliable protection overall.

[0054] Within the scope of the present invention, a technical solution is therefore provided by means of which protective clothing concepts can be implemented that were previously not practically feasible due to application-specific limitations, whereby, within the scope of the invention, increased user safety can be achieved while at the same time significantly simplifying handling for the user. Furthermore, reliable sealing performance is achieved for extremity sections, which are regularly challenging components of protective clothing. By implementing a defined measure for adjusting the clothing during or after the protective clothing has been adjusted,after putting it on, the present invention can provide a solution that is easy and safe to handle for the user and can be reliably implemented with regard to the protective effect to increase the comfort of putting on and wearing protective clothing while at the same time ensuring the protective effect as well as user safety, which stands out clearly in comparison to the prior art.

[0055] The term "seam" used in the context of the present invention is to be understood in particular as a connection of the underlying layers or materials by sewing, wherein at least one yarn or thread is generally used for the seam, which is repeatedly guided through the sewing material in the form of the second layer or the respective layers, wherein the yarn or thread is connected or entwined with the sewing material. Thus, in the context of the seam connecting the second layer and the fastening means, it is in particular a yarn- or thread-based seam. Accordingly, the seam in question is particularly preferably not a threadless connection or not an adhesive seam or welded seam.

[0056] The term "seam region," as used in the context of the present invention, is to be understood in this context in particular as representing a section or region with the overlapping arrangement or positioning of the closure means with the second layer, which is formed by the formed common seam with the corresponding seam-like engagement or connection of the second layer and the closure means. The seam region thus refers in particular to the region in which the underlying layers to be joined, namely in particular at least the second layer and the closure means, are connected or engaged by the common seam.

[0057] Further advantageous developments and refinements of this first aspect of the invention are the subject of the corresponding sub- and auxiliary claims relating to the protective clothing according to the invention and are also disclosed in more detail below in the description of the figures.

[0064] The figure representations according to Fig. 1 to Fig. 18 particularly illustrate the first aspect of the present invention, according to which, according to the invention, protective clothing 1 with a protective function against chemical and / or biological and / or radioactive pollutants and / or poisons (warfare agents) ("ABC or CBRN protective function"), in particular ABC protective clothing ("CBRN protective clothing"), is provided, preferably for civil or military purposes. In particular, the protective clothing 1 is in the form of trousers 2, as shown in Fig. 1 to 3 show. A pair of trousers 3 may comprise elongate extremity portions 4 adapted to be arranged on the legs of a wearer, as schematically shown in the Fig. Show 1 to 3.

[0065] Fig. Figure 7 shows that the protective clothing 1 is also designed in the form of a jacket 3. Not shown in detail is that the protective clothing 1 is designed in the form of a jumpsuit or sweater.

[0066] Particularly preferred is protective clothing 1, such as the Fig. 1 shows, in the form of trousers 2.

[0067] As explained previously, the Fig. 1 to 3, the protective clothing 1 has at least one extremity section 4 for, in particular, partial and / or complete protection of at least one extremity, in particular at least one upper and / or lower extremity, of a wearer of the protective clothing 1, preferably in the worn and / or used state. This extremity section 4 is particularly preferably elongated. A longitudinal extension of the extremity section 4 results in particular in the longitudinal direction of the respective extremity of the wearer that is to be protected by the extremity section 4.

[0068] In the application and / or use state of the protective clothing 1, it is particularly provided that the extremity section 4 surrounds and / or encloses at least one extremity of the wearer, at least in part. In this context, it is understood that areas of the wearer's extremity may protrude from the extremity section 4 in the worn state, in particular the hands and / or feet, which may be protected by additional protective equipment, preferably gloves and / or footwear, if necessary. In particular, a large part of the wearer's extremity, in particular at least 70%, preferably at least 80%, more preferably at least 85%, is covered by the respective extremity section 4 in the worn state.

[0069] The Fig. The protective clothing 1 shown in Figure 1 comprises a multi-layer protective material 5, as is particularly the case for different embodiments in the Fig. 8 to 13.

[0070] Fig. 8 shows that the protective material 5 has several layers, namely at least: (a) a first, in particular flat and / or two-dimensional, layer 6 in the form of a multi-layer, in particular at least two-layer, air-permeable adsorption filter material ("inner layer"), in particular for the adsorption of chemical and / or biological and / or radioactive pollutants and / or toxins, preferably wherein the adsorption filter material has an adsorption layer 6a and a textile carrier layer 6b ("adsorption layer carrier"), and (b) a second, in particular flat and / or two-dimensional, layer 7 in the form of a textile, air-permeable outer material (“outer layer”).

[0071] The protective clothing 1 proposed according to the invention has a widening section 9 which can be opened and / or closed with at least one closure means 8 for selectively widening and / or enlarging the inner and / or outer diameter 10, 11 of the protective clothing 1 in the region of the widening section 9. The widening section 9 is in the Fig. 2 in the closed and in the Fig. 3 in the released state, which can also be referred to as a preferably fully opened and / or, in particular, maximally widened state. For the purposes of the present invention, the released state of the widened section 9 refers in particular to the maximally widened state in which the closure means 8 has been actuated for maximum release. Intermediate states can also preferably be assumed, which can also be considered open—for example, when the closure means 8 has been actuated up to half of the widened section 9.

[0072] The widening section 9 shown in the figures is arranged at least partially, preferably completely, on and / or in the extremity section 4. Accordingly, the widening section 9 can be actuated as needed in a manner predetermined by the user and enable a defined release or removal of the protective material 5. In particular for donning or putting on the protective clothing 1, the widening section 9 offers particular advantages, which can be seen in particular in the fact that when the extremity of a wearer is inserted into the extremity section 4, the inner cross-section of this extremity section 4 can be enlarged, in particular by actuating the closure means 8, which can achieve an enlargement of the inner and / or outer diameter 10, 11. Sliding into the protective clothing can therefore be made easier, thereby improving wearing comfort and / or handling.

[0073] At the same time, damage to the protective material 5 when putting on the protective clothing 1 can be prevented, in particular, since a sufficiently large free space can be provided inside 13 of the protective clothing. In practice, protective clothing 1 according to the present invention is put on with protective equipment that is intended to be at least partially arranged in the protective clothing 1 when worn, such as gloves and / or footwear. The protective clothing according to the invention can reduce the impact of the protective equipment components on the protective material 5, and in particular, tearing of the protective material 5 can be prevented.

[0074] In addition, the sealing and / or the protective effect against toxic and / or harmful substances is also improved. According to the invention, the widening section 9 makes it possible to ensure an optional widening of the inner cross section in the area of ​​the extremity sections 4, which is required in particular for putting on the protective clothing 1. Because the widening section 9 can be converted into a closed state by the closure means 8, this widening can be taken back again after the protective clothing 1 has been put on, or the inner cross section in the area of ​​the extremity section 4 can be reduced. Any passages for gases and / or harmful substances can be significantly reduced in this way, whereby the protective effect can be increased. This reduction achievable with the present invention particularly surpasses measures which only provide a very selective orenable small-area cross-sectional reduction.

[0075] In particular, a defined release or removal of the protective material 5 can occur through the widened section 9, thereby ensuring an optimal fit for a wearer. This is a fundamental difference from conventional measures for adjusting protective clothing, which often involve the formation of a multitude of undefined channel areas that can cause harmful and / or toxic substances to penetrate into the interior 13 of the protective clothing 1 and can arise when the protective material 5 is compressed in the area of ​​the extremity section 4 without the presence of a widened section 9. Such effects, which endanger application safety, can be minimized or avoided within the scope of the invention.

[0076] The Fig. 12 to 14 clearly show that the closure means 8 is only and / or exclusively connected, in particular sewn, to the second layer 7. Alternatively or additionally, the present invention provides that the closure means 8 is, preferably directly, unconnected to the first layer 6.

[0077] In a particularly preferred embodiment, such as in Fig. As illustrated in Figure 14, the closure means 8 is connected to the second layer 7 by sewing in at least one seam area 12, in particular using at least one yarn and / or thread. The sewing enables long-term use of the closure means 8 and the widened portion 9 and provides a secure and stable connection. Furthermore, the use of external substances, such as adhesives, which could potentially interact with the harmful and / or toxic substances, can be dispensed with.

[0078] Preferably, the closure means 8 does not impair the protective and / or adsorption effect of the first layer 6. This is achieved in particular by the fact that no direct fastening and / or connection to the first layer 6 is necessary for fastening the closure means 8. The seam region 12, which preferably connects the closure means 8 and the second layer 7, in particular does not run through the first layer 6, so that preferably the first layer 6 is not perforated by the seam region 12.

[0079] In the wearing and / or application state of the protective clothing 1, the first and second layers 6, 7 are at least substantially in contact with each other, as the Fig. 12. Only in individual connection areas, which are not shown in detail in the figures, in particular in the seam, are the two layers 6, 7 connected to each other, in particular sewn. In the other areas, if necessary, a distance between the two layers 6, 7 can be achieved by pulling the layers 6, 7 apart, which, for example, in the Fig. 13 and Fig. 14. In particular, both layers 6, 7 can be spaced apart from one another, in particular at least substantially over the length of the closure means 8, in particular without the closure means 8 or the widening section 9 hindering this.

[0080] In a preferred embodiment of the present invention, it is provided that the first layer 6 is arranged and / or positioned on the side of the protective clothing 1 facing away from a source of harmful and / or toxic substances when the protective clothing 1 is worn and / or used.

[0081] In other words, the first layer 6 can be arranged and / or positioned facing the interior 13 of the protective clothing, in particular facing the wearer of the protective clothing 1, in the wearing and / or use state of the protective clothing 1.

[0082] The protective effect of the first layer 6 thus acts directly on the side facing the wearer of the protective clothing. Furthermore, in this preferred arrangement, the first layer 6 is protected by the second layer 7 from mechanical stresses and / or external stresses, such as weather influences.

[0083] Equally preferably, the second layer 7 is arranged and / or positioned in the wearing and / or use state of the protective clothing 1 on the side of the protective clothing 1 facing a source of harmful and / or toxic substances, in particular the outer side of the protective clothing 1. This is shown schematically in Fig. 1 shown.

[0084] In other words, when the protective clothing 1 is worn and / or used, the second layer 7 is preferably arranged and / or positioned facing away from the interior 13 of the protective clothing 1, in particular facing away from the wearer of the protective clothing 1. As explained above, this arrangement allows the first layer 6 to be protected from mechanical stress by the second layer 7.

[0085] Furthermore, this arrangement also allows the closure means 8 to be arranged on the outer side of the protective clothing 1, or on the side facing a source of harmful and / or toxic substances. This ensures that the closure means 8 is accessible and operable for the wearer of the protective clothing 1 when the protective clothing 1 is worn.

[0086] Furthermore, the protective clothing 1 is preferably in the form of trousers 2, as shown in the Fig. 1 to 3. In other words, the protective clothing 1 can be designed in the form of a pair of trousers, in particular in the form of outer trousers and / or overtrousers. A pair of trousers 3 has, in particular, two elongated extremity sections 4 that can be arranged on the legs of a wearer.

[0087] In an embodiment not shown in detail, but also preferred, the protective clothing 1 is designed in the form of a jumpsuit, wherein a jumpsuit has four extremity sections 4, in particular for the legs and arms of the wearer. A widening section 9 is arranged on at least one of these extremity sections 4.

[0088] For a further preferred embodiment, the Fig. 7, the protective clothing 1 is designed in the form of a jacket 3, in particular in the form of an outer jacket and / or overjacket. A jacket 3 can have two extremity sections 4, which are intended for placement on the arms of a wearer.

[0089] Also not shown in detail is that in another preferred embodiment of the inventive concept, the protective clothing 1 is designed in the form of a sweater. A sweater, like a jacket 3, can have two extremity sections 4 in which the wearer's arms can be arranged.

[0090] In a preferred embodiment of the protective clothing 1 according to the invention, the extremity section(s) 4 enclose and / or surround the extremity(ies) of the wearer of the protective clothing 1, in particular at least substantially completely, in particular at least in the region of the thigh(s) and lower leg(s) and / or the upper arm(s) and forearm(s) of the wearer of the protective clothing 1.

[0091] Particularly preferably, at least 70%, preferably at least 80%, particularly preferably at least 85%, of the wearer's extremity protected by the extremity section 4 is covered, surrounded, and / or enclosed by the extremity section. In this way, in particular, the extremity of a wearer can be protected at least substantially safely.

[0092] In general, within the scope of the present invention, it can be provided in this context that the widened section 9 is part of the second layer 7 and / or part of the extremity section 4 and / or can be assigned thereto. Most preferably, the widened section 9 is part of the extremity section 4 and comprises the protective material 5 containing the first and second layers 6, 7. Accordingly, the protective effect can also be provided in the region of the widened section 9 in the widened state.

[0093] In addition, as equally in Fig. 1, it can be provided according to the invention that the widened section 9 and / or the closure element(s) 8 is / are arranged and / or positioned on the inner area and / or region of the extremity section 4 facing the body of the wearer of the protective clothing 1. This arrangement enables the closure means 8 and / or the closure means 8 to be protected when worn and / or in use and, in particular, does / do not impair the arrangement of other equipment and / or pockets.

[0094] According to this, particularly in Fig. 1, it can also be provided that the inner area and / or region of the extremity section 4 facing the body of the wearer of the protective clothing 1 extends over at least 40%, preferably at least 30%, of the outer circumference in the circumferential direction of the extremity section 4. Accordingly, in particular the inner region or the inner area of ​​the extremity section 4 is that section of the extremity section 4 which faces the other extremity of the wearer.

[0095] In this regard, it can also be provided that the widened section 9, the closure element 8, and / or the inner area or the inner region of the extremity section 4 are arranged and / or positioned in the area of ​​the inner leg, preferably at least in the area of ​​the inner lower leg, and / or in the area of ​​the inner arm, preferably at least in the area of ​​the inner forearm, of the wearer of the protective clothing 1 and / or face the wearer. As previously explained, this arrangement allows the widened section 9 to be arranged in a protected manner, and the arrangement can further optimize the positioning of additional equipment, pockets, or the like.

[0096] According to a first preferred embodiment of the invention (as also described in Fig. 1), it can generally be provided according to the invention that the extremity section 4 is designed as a trouser section 14, in particular as a trouser leg of the trousers.

[0097] It is not shown in more detail that the extremity section can preferably also be designed as a trouser section 14 of the overall.

[0098] At the Fig. In the preferred embodiment shown in Fig. 7, the extremity section 4 is designed in particular as a sleeve section 15, in particular as a sleeve of the jacket 3, the overalls and / or the sweater.

[0099] The aforementioned extremity sections 4 are subject to high requirements with regard to tightness, particularly when the protective clothing is used to protect persons, which can be optimally ensured in particular by the invention on at least one, in particular on all, extremity sections 4 of a protective clothing.

[0100] In this context, Fig. 1 also shows the preferred embodiment according to the invention, according to which the protective clothing 1 has at least two extremity sections 4, particularly preferably at least two extremity sections 4 designed as trouser sections 14, in particular as trouser legs. This embodiment, with the widening section 9 being arranged on both sides of both trouser sections 14, in particular, enables the wearer's legs to be reliably protected from the penetration of harmful and / or toxic substances into the interior 13 of the protective clothing 1 when in use.

[0101] Fig. Figure 7 shows that, in a further preferred embodiment, at least two extremity sections 4 designed as sleeve sections 15, in particular as sleeves, are particularly preferably provided. In particular, the widening sections 9 are provided on both sleeve sections 15 of the protective clothing 1, which improve the handling and also the protection for the respective extremity.

[0102] Accordingly, as described above, the widening section 9 is preferably arranged on at least two extremity sections 4 of the protective clothing 1, as is clearly shown in the Fig. 1. The Fig. 1, the widening section 9 is arranged on both trouser sections 14, in particular both trouser legs. Similarly, the widening section 9 can be arranged on both sleeve sections 15, in particular both sleeves, of the protective clothing 1. The advantageous properties described above can therefore be ensured in particular for all extremity sections 4 of a protective clothing 1 or a protective clothing garment, which can also be referred to as protective clothing 1 within the meaning of the present invention.

[0103] In this context, it can be provided according to the invention in particular that the widening section 9 extends from an open end 16 of the extremity section 4, in particular of the trouser section 14, preferably of the trouser leg, as in Fig. 1, and / or the sleeve portion 15, preferably the sleeve, as shown in Fig. 7. In this context, it is further preferred that the widening section 9 extends in the longitudinal direction L of the extremity section 4, as is also shown in the Fig. 1 is illustrated.

[0104] In this regard, it can also be provided that the widening section 9 tapers upwards, in particular away from the open end 16 of the extremity section 4, as shown schematically in the Fig. 3 and Fig. 4. A tapered design enables, on the one hand, in particular, an optimized folding and / or compression of the protective material 5 of the widened section 9. On the other hand, the operability and / or handling of the widened section 9 or the closure means 8 can be improved, since, in particular, correct positioning of the material of the widened section 9 before actuating the closure means 8 is not necessary. In particular, the widened section 9 tapers starting from the open end 16 of the extremity section 4 in the longitudinal direction L of the extremity section 4.

[0105] A tapering of the extremity section 4 is further advantageous in that, if necessary, the extremity section 4 itself can also taper in the direction of the open end 16 and can thus better adapt to the shape of the respective extremity.

[0106] According to this, in particular in Fig. 2 and Fig. 3, it can also be provided that the widening section 9 can be transferred by the closure means 8 into an optionally released, preferably widened and / or opened, or closed state.

[0107] In principle, by actuating the closure means 8, intermediate states of the widened section 9 can also be assumed, in which the closure means 8 has not been actuated to the maximum release. These states of the widened section 9 can be referred to in particular as partially released, preferably partially released and / or partially opened, states of the widened section 9. These states also correspond in particular to a partially closed widened section 9 and can thus, in other words, also be referred to in particular as partially closed states of the widened section 9.

[0108] In Fig. 3 schematically shows that, in a preferred embodiment of the present inventive concept, the widened section 9, in particular both in the closed and in the released state, preferably in the widened and / or opened state, comprises a closed, in particular continuous, unopened and / or coherent surface of the first layer 6 and / or the second layer 7. Unlike a zipper, for example in a trouser fly, the closure means 8 does not divide two parts of the protective material 5 spaced apart from one another by an opening. In this way, it is possible for the widened section 9, in particular in every state, to comprise a coherent protective material 5 and thus preferably the protective effect is not impaired by any openings, holes or the like formed in the protective material 5 during use and / or application.

[0109] In other words, in particular, at least the first layer 6 in the widened section 9 is unperforated and / or uninterrupted in the closed and / or opened or released state, in particular in the widened state. The protective effect of the protective material 5 is ensured in particular by the first layer 6, which preferably has no perforations in the widened section 9, in particular in any state of the widened section 9, whereby the wearer's extremities in particular can be well protected.

[0110] In this context, it is particularly understood that the feature that the first layer is continuous and / or unperforated in the widened section 9 does not preclude the presence of perforations in any intended connecting areas and / or seam areas of individual blanks of the first layer 6 or in the connecting area to the second layer 7. These perforations would be present anyway and are not or will not be influenced by the widened section 9.

[0111] In Fig. 6 shows a particularly preferred embodiment in which the widening section 9, in the closed state of the widening section 9, has at least one fold 17 arranged and / or formed in the interior 13 of the protective clothing 1 and / or facing inwards, towards the wearer of the protective clothing 1, with at least two folding legs 18 of the protective clothing 1. The fold 17 enables, in particular, efficient compression and / or folding or stowing of the protective material 5 in the closed state of the widening section 9. Accordingly, the fold 17 can in particular ensure that the protective material 5, in the closed state, does not impair wearing comfort due to annoying bulges in the protective material 5.In the same way, damage to the protective material 5 can be prevented both in the closed state and when the closure means 8 is actuated, since the protective material 5 is allocated a certain space by the formation of the fold 17, which in particular does not make it difficult to actuate the closure means 8, for example by snagging.

[0112] For a further preferred embodiment, as the Fig. 3, it is provided that a side seam 40, in particular a trouser side seam, connecting at least two cuts of the second layer 7 to one another, in particular sewing them together, preferably running at least substantially in the longitudinal direction L of the extremity section 4, is provided and / or arranged in and / or on the widening section 9, preferably at least substantially centrally in the widening section 9.

[0113] What is not shown in more detail is that the side seam 40 can also be a sleeve side seam.

[0114] “Cuts” of the first and / or second layer 6, 7 are to be understood in such a way that, in particular, the first and / or second layer 6, 7 are composed of parts or sections, wherein these parts or sections are referred to as “cuts” within the meaning of the present invention. Cuts of the first and / or second layer are, in particular, connected to one another in the worn and / or used state, preferably sewn. A plurality of cuts can be provided for both the first layer 6 and the second layer 7. Ultimately, the first layer 6 can be formed by connecting the cuts of the first layer 6. In the same way, the second layer 7 can be formed, in particular, by connecting the cuts of the second layer 7.

[0115] Advantageously, in this preferred embodiment of the present invention, in the closed state of the widened section 9, the closure means 8 can functionally replace the side seam 40 and / or be arranged at least substantially at the location where the side seam 40 would be arranged anyway without a widened section 9. A further advantage is that, in the closed state of the widened section 9, the side seam 40 is arranged inside the protective clothing 1 and can thus be protected. The risk of harmful and / or toxic substances penetrating through the side seam 40 can be further reduced in this way.

[0116] In Fig. 6 shows a particularly preferred embodiment in which the fold legs 18 of the fold 17 are separated from one another by the side seam 40 when the widening section 9 is closed.

[0117] This makes it possible, in particular, for the fold 17 to be predetermined and / or determined by the side seam 40, whereby the fold 17 can be formed "automatically" without the wearer having to laboriously fold the fold 17 manually, and the fold legs 18 can be easily predetermined in this way. This leads, in particular, to simplified handling of the protective clothing 1, especially when putting on the protective clothing 1.

[0118] For a further preferred embodiment, Fig. 4 schematically shows that in the open state, the widened section 9 is wedge-shaped. The wedge shape of the widened section 9 increases the wearing comfort of the protective clothing 1 and, in particular, simplifies folding the fold 17 and / or the protective material 5 when closing the widened section 9. Furthermore, the wedge shape can provide an expansion in that section of the extremity section 4 which should be as wide as possible, in particular when putting on the protective clothing 1, but should be reduced as much as possible when in use and / or in the application state. This particularly applies to the area around the open end 16 of the extremity section 4, which should be as wide as possible when putting on the protective clothing 1, for example for wearing protective equipment such as gloves and / or footwear.However, if the protective equipment has been passed through the extremity sections 4, the opening cross-section in this area should ideally be reducible to prevent the risk of toxic and / or harmful substances entering. Within the scope of the invention, these diametrically opposed requirements can therefore be met in a particularly advantageous manner.

[0119] In the Fig. 5 shows a particularly preferred embodiment in which, in the closed state, the fold 17 and / or the fold legs 18 of the widening section 9 is / are formed as a wedge-shaped fold 17 and / or as a wedge-shaped fold leg 18. The fold 17 and the fold legs 18 are in the Fig. 5, since the widening section 9 is shown in the closed state. However, the wedge shape is schematically represented by a dashed line.

[0120] In Fig. 4 further shows that the closure means 8 preferably opens at and / or in the region of the tapered end(s) 19 of the widened section 9, particularly in the open and / or closed state of the widened section 9. The wedge shape of the widened section 9 can therefore also determine the course of the closure means 8 and thus ensure, particularly at the pointed end 19, that preferably no material becomes caught in the closure means 8 at the end of the closure means 8 when the widened section 9 is maximally open.

[0121] An angle α, as shown schematically in the Fig. 3 and Fig. 4, at the tapered end 19 of the wedge-shaped widening section 9, particularly in the open state of the widening section 9, of at least 3°, preferably at least 5°, more preferably at least 10°, and / or from 3° to 70°, more preferably from 5° to 40°, more preferably from 10° to 25°. The aforementioned angles α enable an improved design of the widening section 9.

[0122] In Fig. 3 clearly shows that, in a further preferred embodiment, the closure means 8 extends at least substantially over the entire length, in particular in the longitudinal direction L of the extremity section 4, of the widened section 9. Consequently, the widened section 9 does not protrude relative to the closure means 8. In this way, the entire widened section 9 can be actuated by the closure means 8.

[0123] In a particularly preferred embodiment, it is provided that the maximum width of the extremity section 4 in the closed state of the widening section 9 corresponds to at least 5%, preferably at least 10%, more preferably at least 15%, in particular at least 20%, of the length of the extremity section 4, in particular running in the longitudinal direction L of the extremity section 4. In this way, in particular, an elongated extremity section 4 is obtained which can be used to cover the extremity of a wearer and can consequently adapt to the elongated shape of the extremity of the wearer, whereby optimal protection can be ensured.

[0124] In other words, it is preferably provided that the maximum width of the extremity section 4 in the closed state of the widening section 9 corresponds to between 5% and 60%, preferably between 10% and 40%, more preferably between 15% and 35%, in particular between 20% and 30%, of the length of the extremity section 4, in particular running in the longitudinal direction L of the extremity section 4.

[0125] In Fig. 3 shows, for the preferred embodiment illustrated there, that the maximum width of the extremity section 4 in the released state, preferably in the widened and / or opened state, of the widening section 9 corresponds to at least 6%, preferably at least 12%, more preferably at least 18%, in particular at least 23%, of the length of the extremity section 4, in particular running in the longitudinal direction L of the extremity section 4. This makes it possible, in particular, that the opening cross-section or the inner and / or outer diameter 10, 11 of the extremity section 4 can be sufficiently enlarged to increase handleability and that the protective clothing 1 can be easily and quickly put on even when wearing footwear and / or gloves.

[0126] In other words, the maximum width of the extremity section 4 in the released state, preferably in the widened and / or opened state, of the widening section 9 can correspond to between 6% and 65%, preferably between 12% and 45%, more preferably between 18% and 40%, in particular between 23% and 33%, of the length of the extremity section 4, in particular running in the longitudinal direction L of the extremity section 4.

[0127] In a particularly preferred embodiment, it is provided that the closure means 8 runs continuously and / or uninterruptedly over the entire length of the widening section 9 and / or is designed as a continuous or uninterrupted closure means 8, as is shown schematically in particular in the Fig. 3 is shown.

[0128] In particular, it is provided that the closure means 8 is designed as a zipper 20, as can be seen from the Fig. 4, among other things, is schematically shown. The zipper 20 allows for simple operation with few operating errors, and the zipper 20 is further characterized by its durability and secure closure.

[0129] Preferably, the zipper 20 has two side parts 21, in particular having staples, and a slider 22 that selectively connects the side parts 21 via positive locking. In particular, the side parts 21 of the zipper 20 can delimit the widening section 9, as schematically shown in the Fig. 3 represents.

[0130] In Fig. Figure 6 shows particularly clearly that, in a further preferred embodiment, the closure means 8, in particular the side parts 21 of the zipper 20, is placed and / or laid onto the protective material 5, in particular the second layer 7, preferably completely, and is preferably firmly connected, in particular sewn, to the protective material 5, in particular the second layer 7. In this way, in particular, the functionality of the protective material 5, the first and second layers 6, 7 cannot be impaired, and, moreover, simple adaptation of the closure means 8 is also ensured.

[0131] Preferably, the closure means 8 is connected to the second layer 7 in an unenclosed or unenclosed manner and / or unplugged or unplugged manner and / or arranged on the second layer 7. Consequently, in particular, the functionality of the closure means 8 is also not impaired.

[0132] In Fig. 4 shows that the closure means 8, in particular the zipper 20, preferably has at least two closure elements 23, in particular side parts 21, that can be connected to one another, preferably in a form-fitting manner. The closure elements 23 enable a limitation of the widened section 9 and, furthermore, a secure closure of the widened section 9 in the closed state. The closure elements 23 can be designed to be complementary to one another, at least in some areas, thus ensuring multiple actuation of the closure means 8.

[0133] In Fig. 2 shows a further preferred embodiment in which, in particular, the closure elements 23, in particular the side parts 21, of the closure means 8 are each sewn to the second layer 7, preferably only and / or exclusively to the second layer 7, by at least one seam region 12. Consequently, the seam region 12 does not impair the protective effect of the first layer 6 and / or the first layer 6 as such.

[0134] In the Fig. 3 schematically shows that the widened section 9 preferably extends over at least 40%, in particular over at least 50%, preferably over at least 60%, of the length of the extremity section 4, in particular the trouser section 14, preferably the trouser leg, and / or the sleeve section 15, preferably the sleeve. The widening of the inner opening cross-section of the extremity section 4 can thus be provided over a large part of the length of the extremity section 4, after which the previously described advantages of easy handling of the protective clothing 1 can follow.

[0135] In other words, the widening section 9 can extend over a range of 40% and 100%, preferably a range of 50% to 95%, more preferably a range of 60% to 85%, of the length of the extremity section 4, in particular trouser section 14, preferably the trouser leg, and / or the sleeve section 15, preferably the sleeve.

[0136] In a particularly preferred embodiment, the widening section 9 can lead to a maximum widening and / or enlargement of the inner and / or outer diameter 10, 11 of the extremity section 4, in particular the trouser section 14, preferably the trouser leg, and / or the sleeve section 15, preferably the sleeve, in particular at the open end 16 of the extremity section 4, of at least 3%, preferably of at least 5%, more preferably of at least 5%, in particular of at least 10%. The aforementioned widening allows, in particular, the wearer's extremities to slide easily into the extremity sections 4 when donning the protective clothing 1.

[0137] In other words, the widening section 9 can lead to a maximum widening and / or enlargement of the inner and / or outer diameter 10, 11 of the extremity section 4, in particular of the trouser section 14, preferably of the trouser leg, and / or of the sleeve section 15, preferably of the sleeve, in particular at the open end 16 of the extremity section 4 in a range of 3% to 70%, preferably in a range of 5% to 50%, more preferably in a range of 10% to 40%, in particular in a range of 12% to 30%.

[0138] In further embodiments, the extremity section 4, in particular the trouser section 14, preferably the trouser leg, and / or the sleeve section 15, preferably the sleeve, can be at least substantially tubular, in particular at least substantially cylindrical, at least in the region of the widened section 9 in the closed state of the widened section 9. In this context, it can particularly preferably be provided that the width of the extremity section 4, in particular the trouser section 14, preferably the trouser leg, and / or the sleeve section 15, preferably the sleeve, in the closed state of the widened section 9, is at least substantially the same, preferably across and / or in the longitudinal direction L of the extremity section 4.

[0139] According to a further preferred embodiment, as shown in Fig. 2, the extremity section 4, in particular the trouser section 14, preferably the trouser leg, is tapered at least in the region of the widened section 9 in the closed state of the widened section 9, towards the open end 16 of the extremity section 4, in particular running in the longitudinal direction L of the extremity section 4. In this way, in particular the fit of the extremity section in the closed state of the widened section 9 can be improved, since the tapered extremity section 4 can adapt to a tapered extremity of the wearer, whereby ultimately the protective effect against harmful and / or toxic substances can also be improved when the protective clothing 1 is worn.

[0140] In the Fig. 7 schematically shows that the sleeve section 15, preferably the sleeve, is preferably also tapered, at least in the region of the widened section 9 in the closed state of the widened section 9, towards the open end 16 of the extremity section 4, in particular extending in the longitudinal direction L of the extremity section 4. This can result in the advantages described above.

[0141] In this context, it is particularly preferred if the minimum width of the extremity section 4 in the tapered region of the extremity section 4 corresponds to at least 60%, preferably at least 70%, more preferably at least 80%, in particular at least 85%, and / or from 60% to 95%, preferably from 70% to 90%, more preferably from 75% to 85%, of the maximum width of the extremity section 4 in the tapered region of the extremity section 4.

[0142] In the Fig. 2 and Fig. 3 schematically shows that preferably in the interior 13 of the protective clothing 1, in particular in the interior 13 of the extremity section 4, in particular of the trouser section 14, preferably of the trouser leg, a gaiter (“inner gaiter”) 24 is provided for arrangement on the foot, on the footwear and / or on the lower extremity, in particular on the leg, of the wearer.

[0143] The gaiter 4 makes it possible to ensure that the protective clothing 1 does not shift and / or slip, in particular when the protective clothing 1 is worn and / or used. The gaiter 4 can preferably also be connected to external equipment, such as footwear, and in this way position in particular the extremity section 4 relative to the footwear.

[0144] Furthermore, when putting on the protective clothing, the first layer 6 can be protected from damage by the material of the gaiter 24. At the same time, the gaiter facilitates sliding into the extremity section 4, especially when protective equipment is on.

[0145] The wearing comfort of the protective clothing 1 can also be improved by the gaiter 24, in particular by the gaiter 24 and not the first layer 6 being adjacent to the extremity of the wearer.

[0146] In particular, the gaiter 24 is connected, in particular sewn, at least to the first layer 6, in particular only and / or exclusively to the first layer 6. This enables the internal arrangement of the gaiter 24, which, in the application state, only protrudes a small portion relative to the extremity portion 4.

[0147] In this context, it is particularly preferred that the gaiter 24 extends at least over the length of the widened section 9. The protective clothing 1 can therefore be positioned by the gaiter 24, in particular both in the open and in the closed state of the widened section 9.

[0148] In this context, it is particularly preferred that the opening width of the gaiter 24 at least substantially corresponds to the opening width of the extremity section 4, preferably of the trouser section 14, preferably of the trouser leg, in particular the inner diameter 10 of the extremity section 4, preferably of the trouser section 14, preferably of the trouser leg, in the released state, preferably in the widened and / or opened state, of the widening section 9 and / or exceeds this, as is clearly shown in Fig. 3. The gaiter 24 therefore does not represent any further obstacle when inserting the wearer's extremities into the respective extremity sections 4 and consequently does not impair the achievement of the previously described advantages of the widening section 9 according to the invention.

[0149] In this context, it is advantageously provided that the gaiter 24 can be reduced in its opening cross-section via a fastening means 25. The fastening means 25 can, in particular, have an elastic band and a locking element for securing or releasing the elastic band as needed. The fastening means 25 enables the gaiter 24 to be fixed in place during use. The fastening means 25 can also have a barrier effect, which is particularly advantageous when combined with the widened section 9 and allows for an increased barrier effect against the penetration of harmful substances.

[0150] In the Fig. 15, a further preferred embodiment provides that the protective clothing 1 has at least one opening section 27, in particular a trouser fly, which can be opened and / or closed with a further closure means 26, for optionally opening the protective clothing 1 in the region of the opening section 27. The opening section 27 enables further simplified donning of the protective clothing 1, which, depending on the fit, requires the opening section 27 to be opened as needed.

[0151] It is not shown in more detail that the opening section is and / or forms a divisible opening section 27 of a jacket 3, a sweater or an overall.

[0152] The opening section 27 can be specially protected according to the invention, as explained below: In this context, the further closure means 26, in the closed state, can be covered and / or overlapped on the underside and / or on its side facing the interior 13 of the protective clothing 1 and on the top side and / or on its side facing the pollutant and / or toxic substance source, respectively, with a material section 28a, 28b of at least the first layer 6, in particular a material section 28a, 28b of the protective material 5. This arrangement enables, in particular, at least "double protection", namely protection on the top and bottom sides of the further closure means 26 in the closed state of the opening section 27, as shown in Fig. 17 is particularly clearly shown schematically in the closed state of the opening section 27.

[0153] In this context, it is particularly preferred that the additional closure means 26 be designed to be liquid-repellent, preferably water-repellent, in particular waterproof, and / or airtight or windproof. This provides additional protection for the wearer in the area of ​​the additional closure means 26, whereby, combined with the top and bottom arrangement of the respective material sections 28a, 28b, "triple protection" of the additional closure means 26 can be ensured.

[0154] In addition to the widened section 9, the opening section 27 creates a user-friendly and safer protective clothing 1, which is characterized by effective application of the protective clothing 1, but despite this improved manageability, does not lead to a reduction in the protective effect in use. Accordingly, the opening section 27 and the widened section 9 develop a synergistic effect and provide an overall efficiently usable protective clothing 1.

[0155] In this context, it is generally preferred that the further closure means 26 comprises at least two further closure elements 29 that can be connected to one another, preferably in a form-fitting manner. The further closure elements 29 can, in particular, be designed to complement one another in some areas and, in particular, ensure a form-fitting connection of the further closure means 26.

[0156] Particularly preferably, the further closure means 26 is designed as a further zipper 30, preferably wherein the further zipper 30 has two side parts 31, in particular having staples, and a slider 32 optionally connecting the side parts 31 via positive locking, as shown in the Fig. 15, Fig. 16 and Fig. 18 is shown schematically. Preferably, the side parts 31 of the further zipper 30 delimit the opening section 27.

[0157] In Fig. 16 shows that the protective clothing 1 has and / or forms an opening 33 in the open state of the opening section 27. In particular, in the open state of the opening section 27, two partial sections of the protective clothing 1, on each of which a further closure element 29 of the further closure means 26 is arranged, are spaced apart from one another and / or these partial sections are separated from one another, as is clearly shown in a schematic representation Fig. 16 shows.

[0158] The opening 33 allows the protective clothing 1 to be widened in order to put on the protective clothing 1.

[0159] In Fig. 16 further shows that at least one material section 28a designed as a lower cover section 34 is arranged on at least one partial section of the protective clothing 1, according to which in particular the previously shown protection of the opening section 27 can be achieved.

[0160] Furthermore, in this context, it is further provided that the lower cover section 34 protrudes from the partial section on which the lower cover section 34 is arranged.

[0161] In addition, the lower cover section 34 can, at least in part, preferably completely, cover and / or overlap the further closure means 26 on the side facing the wearer of the protective clothing 1 when the further closure means 26 is closed. This arrangement also results in the previously described protective effect provided by the material section 28a.

[0162] In this context, it is further particularly preferably provided that the further closure means 26 is covered and / or covered on the upper side, in particular on a side of the protective clothing 1 facing the harmful and / or toxic substance source, by a material section 28b designed as an upper cover section 35, at least in some areas, preferably completely, in the closed state of the further closure means, as shown schematically in the Fig. 15 is shown.

[0163] The upper cover section 35 can be arranged on at least one partial section of the protective clothing 1, in particular on the partial section of the protective clothing 1 on which the lower cover section 34 is also arranged, as is also the case with the Fig. 15 shows. Both material sections 28a, 28b can therefore be arranged on the same subsection, thus simplifying the application of the protective clothing 1 and optimizing the protective effect.

[0164] In Fig. 15 further shows that the upper cover section 35 preferably protrudes from the partial section on which the upper cover section 35 is arranged, thus extending the protected area even when the opening section 27 is partially opened.

[0165] It is further particularly preferred that the further closure means 26 is designed to be liquid-repellent, preferably water-repellent, in particular waterproof, and / or air- or wind-tight, which leads to an improvement in the protective effect, as already explained above.

[0166] In this case, the additional closure elements 29, in particular the side parts 31, of the additional closure means 26 can preferably have, at least in some areas, preferably completely, a plastic coating and / or plastic film, preferably a polyurethane coating and / or a polyurethane film, in particular on the side of the protective clothing 1 facing the source of the harmful and / or toxic substance, and / or can be formed at least in some areas, preferably completely, from a plastic, preferably polyurethane. The aforementioned coating ensures protection against liquids and / or wind and prevents the penetration of liquids via the additional closure means 26, thus further improving the protective effect of the entire protective clothing 1.

[0167] According to the invention, the adsorption layer 6a can be discontinuous and / or gas-permeable.

[0168] In a further particularly preferred embodiment of the present inventive concept, it is provided that the adsorption layer 6a is connected to the textile carrier layer 6b via an adhesive layer 36 applied to one side of the textile carrier layer 6b.

[0169] In particular, the adhesion promoter layer 36 can fix and / or adhere the adsorption layer 6a.

[0170] In addition, the adhesive layer 36 can be present and / or formed as a water vapor and / or gas permeable and / or discontinuously formed adhesive layer, preferably based on an adhesive polymer.

[0171] Advantageously, the adhesive layer 36 provides or enables a bond of the adsorption layer 6a that is particularly durable for long-term use of the protective clothing 1 and, moreover, is also optimally designed, particularly with regard to the protective effect of the protective material 5, preferably due to its discontinuous configuration. The adhesive layer 36 can therefore, in particular, ensure the correct positioning of the adsorption layer 6a and thus contribute to improving the protective effect of the protective material 5 against harmful and / or toxic substances.

[0172] In a particularly preferred embodiment, it is provided that the first layer 6 is and / or is designed to be gas-permeable, in particular air-permeable.

[0173] In particular, it can be provided that the first layer 6 is present and / or formed as a gas-permeable, in particular air-permeable, preferably textile, sheet material.

[0174] In this context, the textile carrier layer 6b can be present and / or formed as a preferably gas-permeable, in particular air-permeable, textile fabric.

[0175] In general, in this context, it can further be provided that the textile carrier layer 6b is designed as a knitted fabric, in particular as a warp-knitted fabric (knitted fabric) or a knitted fabric (knitted fabric), woven fabric, scrim or textile composite material, in particular as a knit fabric.

[0176] Furthermore, according to a preferred embodiment, it can be provided that the textile carrier layer 6b has a basis weight in the range of 10 g / m 2 up to 350 g / m 2 , especially in the range of 20 g / m 2 up to 300 g / m 2, preferably in the range of 30 g / m 2 up to 250 g / m 2 , particularly preferably in the range of 50 g / m 2 up to 175 g / m 2 , in particular determined according to DIN EN 12127 1997-12-00, preferably after 24 hours of conditioning at a temperature of 20 °C and a relative humidity of 65%.

[0177] Furthermore, with regard to the adsorption layer 6a of the first layer 6, the following embodiments have proven particularly advantageous within the scope of the present invention. Thus, the invention provides, in particular, for the adsorption layer 6a to be discontinuous. In particular, the adsorption layer 6a is gas-permeable, preferably air-permeable.

[0178] As shown in the enlarged section according to Fig. 8 and beyond in the Fig. 9 to 13, it is particularly provided that the adsorption layer 6a comprises adsorber particles 6c, in particular a plurality of individual and / or discrete adsorber particles 6c, or is formed therefrom. According to the invention, the first layer 6 is constructed in at least two layers (cf., for example, Fig. 8 and Fig. 13). Fig. Figure 8 illustrates a two-layer structure of the first layer 6, while Fig. 9 to 13 illustrate three-, four-layer and five-layer structures.

[0179] In a further, likewise preferred, in particular alternative, embodiment, it is provided that the adsorption layer 6a comprises and / or is formed from adsorber fibers and / or adsorber filaments, in particular activated carbon fibers and / or activated carbon filaments, preferably in the form of an activated carbon fiber sheet.

[0180] In general, the adsorbent particles 6c of the adsorption layer 6a can be selected from the group of (i) in particular particulate activated carbon and / or activated carbon particles, preferably in the form of activated carbon particles in granular form (“granular carbon”) or activated carbon particles in spherical form (“spherical carbon”); (ii) zeolites, in particular natural and / or synthetic zeolites; (iii) molecular sieves, in particular zeolitic molecular sieves, synthetic molecular sieves and / or in particular synthetic molecular sieves based on carbon, oxides and / or glasses; (iv) metal oxide and / or metal particles; (v) ion exchange resins, in particular polydisperse and / or monodisperse cation and / or anion exchangers, in particular of the gel type and / or macroporous type; (vi) inorganic oxides, in particular silicon dioxides, silica gels and / or aluminum oxides; (vii) porous organic polymers and / or porous organic-inorganic hybrid polymers and / or metal-organic framework materials, in particular MOFs (Metal Organic Framework), COFs (Covalent Organic Framework), ZIFs (Zeolite Imidazolate Framework), POMs (Polymer Organic Material) and / or OFCs; (viii) mineral granules; (ix) clathrates; and (x) mixtures and / or combinations thereof; (i) being particularly preferred.

Particularly preferably, the cover layer 37 is present as a preferably gas-permeable textile fabric and / or is designed as such.

[0185] The cover layer 37 can equally function as the outer layer of the first layer 6 (in particular on the side of the first layer 6 facing away from the wearer or user in the wearing or use state of the protective clothing 1), as shown in Fig. 13 is shown schematically. In the Fig. 11, however, shows a further preferred embodiment in which a particle and / or aerosol layer 39, which will be discussed below, forms the outer layer of the first layer 6.

[0186] In the Fig. 13 schematically shows the application of the protective material 5, in which a distance between the first layer 6 and the second layer 7 can be made possible except in possible connecting areas, in particular in seam seams or seam seam areas. This distance is shown in the Fig. 13. Such a distance can also be made possible, in particular, in the non-directly connected areas of the layers 6, 7, for the layer structures of the protective material 5 shown in the other figures.

[0187] The cover layer 37 can therefore protect the adsorption layer 6a from damage, particularly due to mechanical forces. This enables long-term use of the protective clothing 1 with a high level of protection against toxic and / or harmful substances.

[0188] In a further preferred embodiment, each of which is described in the Fig. 1 to 3, the protective clothing 1 has, in and / or on the extremity section 4, in particular in the lower region facing the open end 16 of the extremity section 4, an adjustment means 38 for variably adjusting the inner and / or outer diameter 10, 11 of the extremity section 4, in particular in the region of the adjustment means 38. Preferably, the adjustment means 38 enables the extremity section 4 to rest and / or nestle precisely against the extremities and / or other items of clothing, in particular footwear and / or gloves, in the region of the extremities of the wearer.

[0189] The adjustment means 38 can be formed in particular by a hook and loop fastener connected to the second layer 7, preferably only and / or exclusively to the second layer 7, as shown in the Fig. 1 to 3. In addition to the defined or predetermined widening and reduction of the inner cross-section in the extremity section 4 by the widening section 9, the adjustment means 38 now creates additional variable adjustability of the extremity section 4 for a precise fit to the extremities of the wearer. In particular, the adjustment means 38 is only actuated when the protective clothing 1 has been put on and the widening section 9 has been transferred to the closed state. Fine adjustment can then be carried out by the adjustment means 38. In this embodiment according to the invention, the wearer of the protective clothing 1 is thus given the option of optimally adapting the protective clothing 1 to his or her body shape, wherein the widening section 9 according to the invention particularly improves the wearing comfort and the donning of the protective clothing 1.

[0190] It is particularly preferred within the scope of the present invention if the widening section 9 is combined with the adjustment means 38 and the fastening means 25, if a gaiter 24 is provided, as a measure for efficient and secure adjustment of the protective clothing 1 according to the invention. In this way, three different means are provided in a protective clothing 1 according to the invention, which clearly complement one another in their individual effects, allowing quick and uncomplicated donning of the bulwark clothing 1 and, moreover, specifically quick, individual, and precisely fitting adjustment of the protective clothing, which is essential to enable the best possible protective effect of the protective clothing 1. In this respect, there is a synergistic effect of the various closure and adjustment means, which is significantly beneficial to the protective clothing 1 according to the invention as a whole.

[0191] In addition, the Fig. 10 and Fig. 11 each show embodiments according to the invention, according to which the first layer 6 additionally has a particle and / or aerosol filter layer 39, preferably a particle and aerosol filter layer 39.

[0194] On this basis, the first layer 6 can additionally be equipped with particle or aerosol filter properties. This further increases the protective function against harmful or toxic substances, whereby, as a result of this inventive measure, the adsorption layer 6a is further relieved and thus does not deplete as quickly. This can further extend the use or wear time of the protective clothing 1 according to the invention.

[0195] In this context, the particle and / or aerosol filter layer 39 can be present and / or formed as a gas-permeable textile fabric comprising or formed from a plurality of individual textile fibers.

This can relieve the adsorption layer 6a of the burden of absorbing pollutants or toxic substances, since these can largely already be absorbed by the particle or aerosol filter layer 6e.

[0197] Furthermore, the particle and / or aerosol filter layer 39 can be designed to be gas-permeable, in particular air-permeable, and / or water vapor-permeable, preferably gas-permeable, in particular air-permeable, and water vapor-permeable, preferably air-permeable and water vapor-permeable.

[0245] The present invention is illustrated by the following embodiments, which, however, are not intended to limit the present invention in any way. EXAMPLES OF IMPLEMENTATION:

[0246] The protective function of protective clothing according to the invention against harmful or toxic substances, in particular chemical warfare agents, is characterized and determined based on Method 2.2 of CRDEC-SP-84010 and with respect to bis[2-chloroethyl] sulfide (= mustard gas or HD). This method determines the barrier effect of protective clothing or a protective material against mustard gas, with the quality of the protective function or barrier effect increasing with decreasing penetration values.

[0247] In particular, this determination method involves a so-called convective flow test with mustard gas; for this purpose, an air stream containing mustard gas is allowed to act on the test material at a constant flow resistance and a flow velocity of approximately 0.45 cm / s, and the area-related breakthrough quantity is determined after 24 hours (80% relative humidity; 32 °C; 10 1 µl HD / 12.56 cm 2 )

[0248] According to the applicant's specification, the barrier effect against mustard gas, determined according to method 2.2 of CRDEC-SP-84010, should be less than 4 µg / cm 2 per 24 hours.

[0249] First, a multi-layer protective material known per se, as previously described in detail, used according to the invention (ie protective material 5 according to Fig. 10), whereby the multi-layer protective material is provided in accordance Fig. 10 on the one hand, an air-permeable multi-layer adsorption filter material acting as an inner layer for the adsorption of chemical and / or biological and / or radioactive pollutants and / or toxic substances (= first layer 6 according to Fig. 10) and on the other hand a textile air-permeable outer material acting as an outer layer (= second layer 7 according to Fig. 10), which is also impregnated with an oleophobic and hydrophobic coating. The adsorption filter material (“first layer 6” according to Fig. 10) itself is multi-layered and comprises, viewed from the inside out (ie viewed from the carrier to the outside), a textile carrier layer or a textile adsorption layer carrier (reference number no. 6b according to Fig. 10) on which a plurality of adhesive (polymer) dots (reference number no. 36 according to Fig. 10) are applied, to which in turn discrete adsorber particles (reference number no. 6c according to Fig. 10) in the form of activated carbon beads are permanently fixed or glued, which form the adsorption layer (reference number no. 6a according to Fig. 10). A textile particle and aerosol filter layer (reference number 39 according to Fig. 10) to further increase the protective function against harmful or toxic substances. This results in a multi-layered, air-permeable protective material (ie protective material 5 according to Fig. 10) in the form of a laminate. Characterization of the materials used for the multi-layer protective material

[0250] Multi-layer adsorption filter material (= first layer 6 according to Fig. 10): • textile carrier layer 6b: textile knitwear, surface weight approx. 80 g / m 2 (determined according to DIN EN 12127 1997-12-00 after 24 hours of conditioning at a temperature of 20 °C and a relative humidity of 65%); • Adhesive (polymer) 36: Polyurethane (PU), application quantity approx. 35 g / m 2 , surface of the carrier layer 6b covered with adhesive (polymer) to less than 40%; • Adsorption layer 6a or adsorber particles 6c: discrete activated carbon particles in spherical shape (“spherical carbon”), diameter of the adsorber particles: 0.04 mm to 1 mm, application quantity: approx. 90 g / m 2, activated carbon particles based on a polymer-based spherical activated carbon (PBSAC) (produced from a particulate starting material based on organic polymers, namely sulfonated organic polymers based on styrene / divinylbenzene copolymers, by carbonization and subsequent activation of the starting material, wherein the content of divinylbenzene in the starting material is in the range of 2 wt.% to 10 wt.%, based on the starting material); • Particle and aerosol filter layer 39: gas-permeable textile fabric (non-woven) made of a large number of individual synthetic textile fibers with fiber diameters in the range of 50 nm to 10 µm, surface weight of approx. 50 g / m 2 (determined according to DIN EN 12127 1997-12-00 after 24 hours of conditioning at a temperature of 20 °C and a relative humidity of 65%).

[0251] Outer material (= second layer 7 according to Fig. 10): breathable, textile fabric in the form of a woven fabric, weight approx. 140 g / m 2 (determined according to DIN EN 12127 1997-12-00 after 24 hours of conditioning at a temperature of 20 °C and a relative humidity of 65%), oleophobic and hydrophobic treatment by impregnation or coating with a fluorinated polymer. Testing on multi-layer protective material

[0252] As a reference, the barrier effect against mustard gas is first determined on an unprocessed sample (10 cm x 10 cm) of this multi-layer protective material according to method 2.2 of CRDEC-SP-84010: < 0.08 µg / cm 2 per 24 hours. Tests on the protective clothing according to the invention

[0253] In a manner known per se, a protective clothing according to the invention with a protective function against chemical and / or biological and / or radioactive pollutants and / or poisons (warfare agents) (“ABC or CBRN protective function”) in the form of trousers is produced from a plurality of textile pieces of the previously described multi-layer protective material, as described in detail above and, for example, in Fig. 1 to 6, wherein the individual textile pieces of the previously described multi-layer protective material are each joined together by sewing.

[0254] As previously described in the general part, the protective clothing in the form of trousers has two extremity sections for protecting the extremities (here: legs) of a wearer of the protective clothing when worn and / or in use, wherein the extremity sections completely surround or enclose these two extremities of the wearer when worn and / or in use. The protective clothing in the form of trousers, each completely arranged on or in the extremity section, has a widening section that can be opened or closed with at least one closure means (here: zipper) for optionally widening or enlarging the inner and / or outer diameter of the protective clothing in the form of trousers in the region of the widening section, wherein the closure means is only or exclusively connected to the second layer (i.e. to the outer material), namely sewn, or wherein the closure means is unconnected to the first layer (i.e.the adsorption filter material).

[0255] At the so-called widening section (reference number no. 9 according to Fig. 1 to 6), the barrier effect against mustard gas is determined according to method 2.2 of CRDEC-SP-84010, both in the closed state of the widening section (cf. Fig. 2) with < 0.08 µg / cm 2 per 24 hours as well as in the open state of the widening section (cf. Fig. 3) also with < 0.08 µg / cm 2per 24 hours. This shows that, through the inventive design of the widened section and through the combined use of the previously described multi-layer protective material, the protective function against chemical and / or biological and / or radioactive pollutants and / or toxic substances (warfare agents) ("ABC or CBRN protective function") is fully retained, and this with improved wearing comfort, in particular with improved donning and / or application and / or adaptability (i.e. adaptability to a user or wearer or when worn), of the protective clothing according to the invention compared to a protective clothing without such a widened section. In this way, the protective clothing trousers according to the invention can be quickly and easily put on over existing clothing, including footwear, etc. (as overtrousers, so to speak), without the protective performance being impaired.

[0256] Further tests are carried out on the opening section 27 in the form of a trouser fly (cf. Fig. 15), which is provided with a further closure means in the form of a zipper (reference number no. 30 according to Fig. 18) with two closure elements or side parts (reference numbers 29 and 31 according to Fig. 15 and Fig. 16) is designed to be lockable or openable.

[0257] When this opening section 27 is closed, the tests described below are carried out.

[0258] As a reference, protective clothing in the form of trousers as described above serves, in which the closure means of the opening section 27 is a conventional, i.e., water- and air-permeable zipper, which is also designed to be exposed, i.e., without a top or bottom cover. Here, the barrier effect against mustard gas is measured according to method 2.2 of CRDEC-SP-84010 with > 10 µg / cm2 per 24 hours (ie outside the applicant's specifications). However, if, in accordance with the invention, this zipper is additionally provided with a cover section on the top and bottom (reference numerals 34 and 35 according to Fig. 15 and Fig. 16) made of the multi-layer protective material described above or alternatively only of the adsorption filter material (= first layer) of the multi-layer protective material described above, the barrier effect against mustard gas is determined according to method 2.2 of CRDEC-SP-84010 to a value of 2.8 µg / cm 2 per 24 h or 2.9 µg / cm 2 per 24 hours (i.e. within the applicant's specifications).

[0259] In another test specimen of the previously described protective clothing in the form of trousers, which is also in accordance with the invention, a liquid-repellent, i.e. water-repellent, in particular waterproof, and wind- or airtight zipper (zipper made of polyurethane (PU) with additional PU side sections of the zipper) is used as the closure means of the opening section 27, which results in a barrier effect against mustard gas according to method 2.2 of CRDEC-SP-84010 of 1.8 µg / cm 2 per 24 hours. If this zipper is additionally provided with a cover section on the top and bottom (reference numbers 34 and 35 according to Fig. 15 and Fig.16) is covered or covered with the previously described multi-layer protective material or alternatively only with the adsorption filter material (= first layer) of the previously described multi-layer protective material, the barrier effect against mustard gas is determined according to method 2.2 of CRDEC-SP-84010 to values ​​of < 0.08 µg / cm 2 per 24 hours.

[0260] In this way, protective clothing is obtained which overall meets the applicant's requirements or specifications regarding barrier effect against harmful and toxic substances.

[0261] Overall, within the scope of the present invention, also against the background of the above statements, a high-performance protective clothing is provided which has improved wearing comfort, in particular improved donning behavior and / or application and / or adaptability (ie adaptability to a user or wearer or in the worn state), but in this context at the same time an excellent protective function against harmful and toxic substances is also provided and, in addition, excellent application properties are achieved, for example with regard to the provision of high air permeability with an overall low basis weight.
