Description

[0001] ABC protective clothing with protective function against chemical and / or biological and / or radioactive pollutants and / or toxins

[0002] 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 toxins (such as hazardous substances, combat agents or the like), as it can be used in particular in the military and civilian sectors.

[0003] In particular, the present invention relates specifically to ABC protective clothing or CBRN protective clothing (where ABC = atomic, biological, and chemical, and, synonymously, CBRN = chemical, biological, radiological, and nuclear; the terms ABC on the one hand and CBRN on the other 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 ABC or CBRN protective clothing, such as that which can be used in particular for military purposes and also for civilian purposes (for example, in the field of hazard prevention, firefighting, or disaster relief, or the like).

[0004] Against this background, the present invention relates in particular to protective clothing with a protective function against chemical, biological, or radioactive pollutants or toxins (i.e., chemical pollutants and / or toxins, biological pollutants and / or toxins, and / or radioactive pollutants and / or toxins), such as chemical warfare agents, wherein the protective clothing according to the invention has at least one extremity section for the, 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 application state.

[0005] The present invention further relates to a method for manufacturing protective clothing with a protective function against chemical, biological, or radioactive pollutants or toxins (i.e., chemical pollutants and / or toxins, biological pollutants and / or toxins, and / or radioactive pollutants and / or toxins), such as chemical warfare agents.

[0006] The present invention also relates to the use of a widening section to improve the wearing comfort and / or the putting on and / or the adaptability (i.e., adaptability to a user or wearer or in the wearing state) of protective clothing with a protective function against chemical and / or biological and / or radioactive harmful and / or toxic substances (warning agents) ("ABC or CBRN protective function"), in particular ABC protective clothing ("CBRN protective clothing"), preferably for civilian or military purposes, especially in the form of trousers, a jacket or an overall, preferably in the form of trousers.

[0007] Toxic substances generally pose a high risk, causing adverse health effects for anyone who comes into contact with them. Therefore, exposure or contact with these substances, for example through skin or mucous membrane contact, inhalation, ingestion, or similar means, should be avoided or at least minimized. This is especially important given that the health risks and toxic potential of such substances can be significant, and even contact with or ingestion of small amounts can lead to lasting health problems and even death. It should also be noted that toxins and pollutants can exist in numerous chemical and physical forms, such as gases, liquids, or solids, and as finely particulated aerosols or other particles.from pollutant particles or the like that are present in the air, especially the ambient air.

[0008] Against this background, there is a great need to provide appropriate protective clothing with ABC or CBRN protection to people at risk of coming into contact with toxic or hazardous substances, such as soldiers, firefighters, police officers, members of special or special units, or the like, in order to prevent the absorption of such toxic or hazardous substances during operations in contaminated or polluted environments by wearing the protective clothing.

[0009] Especially for groups of people, such as soldiers, firefighters, police officers, members of special forces, or similar personnel, who are at increased risk of coming into contact with toxic or hazardous substances, it is particularly important and necessary to ensure appropriate protection against these substances. Often, toxic or hazardous substances can be absorbed through the skin in addition to the respiratory system, which poses a significant risk. Therefore, it is often necessary to have appropriate protective clothing (ABC or CBRN protective clothing) available to prevent contact of the toxic or hazardous substances with the skin or body. In this context, such protective clothing, which can take the form of protective suits, jackets, or similar garments, often also includes appropriate headgear.Head coverings, such as hoods or balaclavas, are worn. Such protective clothing, such as protective suits, jackets, or similar garments, is also often designed to be compatible with protective devices against the oral ingestion of harmful substances, such as gas masks.

[0010] To improve wearing comfort while maintaining a high level of protection against harmful substances, air-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 substances. Such protective systems offer improved wearing comfort and generally good protection against harmful substances due to the increased exchange of air and water or water vapor. In some cases, the adsorption material used in such protective clothing is positioned on the side of the material facing the wearer, allowing any harmful substances that have previously penetrated the material to be absorbed by the adsorption material.

[0011] In this context, the general purpose of ABC or CBRN protective clothing is to provide the wearer or user with optimal or enhanced protection against hazardous or toxic substances, in particular insofar as the wearer or user of such protective clothing is, on the one hand, as well as being protected in the best possible way and, on the other hand, being able to commence and carry out their operational activities as quickly and efficiently as possible, independently and, moreover, as unhindered as possible.

[0012] Therefore, in addition to providing appropriate protection against toxic or chemical agents, the comfort and ease of donning and wearing protective clothing play a crucial role, both in terms of a good fit and the possibility of uncomplicated, efficient, and, ideally, autonomous donning. A major challenge in providing such protective clothing is to offer the most comprehensive and / or versatile, or even full-surface and reliable, protection against a multitude of different toxic or harmful substances that exist in various (physicochemical) forms. The often conflicting requirements of providing a high level of protection on the one hand and a high level of wearing comfort on the other must be carefully considered.In particular, the requirements of a relatively uncomplicated way of putting on the clothing, on the other hand, should be equally fulfilled in one and the same material.

[0013] With regard to protective clothing, it is also necessary to ensure the longest possible and most versatile protection against toxins and pollutants. This protective function must be guaranteed even at high local concentrations of toxins or pollutants (for example, if a drop of a toxin or pollutant directly lands on the protective clothing). Furthermore, the protective function should be guaranteed for extended periods and under adverse operating conditions, including at particularly critical sections and areas of the protective clothing, such as the ends and transition zones, for example, head and neck openings, face openings, abdominal and pelvic openings, and especially arm and hand openings, as well as leg and foot openings. The same applies to transition and connection areas between different parts of the garment.Protective clothing worn simultaneously, 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), is particularly problematic. These areas, sections, and transition zones pose a significant challenge, both in terms of providing an efficient and lasting seal against the ingress of harmful or toxic substances and in terms of enabling the protective clothing to be donned (and removed) as autonomously and efficiently as possible.

[0014] To improve donning comfort while maintaining a high level of protection against harmful or toxic substances, the prior art generally includes measures (or avoidance strategies) such as providing one-piece, oversized protective suits or incorporating 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 a low level of comfort and reduced handling, particularly when donning the suit quickly. This is especially true regarding the insertion of extremities through the sleeves or trouser legs, as well as the correct positioning of the suit. Consequently, functionality and wearing comfort are often insufficient.Self-donning of one-piece protective suits by the wearer is therefore only possible with considerable effort and is not very time-efficient. There is also a risk of damage to the protective clothing from undergarments or other protective equipment, such as footwear or gloves. This is particularly true for sections of the protective clothing that follow the wearer's basic body shape, i.e., sleeves or trouser legs of a protective suit, which typically taper from the base of the limb to the end, making it challenging to put on, for example, footwear or protective undergarments.

[0015] Multi-section protective suits typically present the same problem (tapered extremity sections). If extremity sections do not taper, there is an increased risk of contaminant penetration due to a larger remaining gap. Furthermore, the sealing performance and / or the handling of adjustment or closure devices may be insufficient if the narrowing of an extremity section is very localized or limited. Additionally, donning the protective clothing often requires a high degree of precision or dexterity, which may not always be possible, for example, due to the wearing of gloves or safety footwear.

[0016] The design of protective clothing thus operates within a particularly contradictory field of tension: on the one hand, the requirement for quick, easy, and independent donning of protective clothing, combined with sufficient wearing comfort and guaranteed freedom of movement and flexibility for the user. On the other hand, the openings in protective clothing, in particular, represent a critical structure with regard to the unwanted penetration or ingress of harmful or toxic substances. The same applies to the transition or contact area between different elements of protective clothing, for example, a jacket and trousers, or a jacket or jacket sleeve and a glove, or trousers and...between a trouser leg on the one hand and a shoe on the other. In particular, these transition areas are associated with a corresponding risk of excessive exposure of a person located in the danger zone to the harmful or toxic substances in question.

[0017] Likewise, these transition areas regularly present weak points or complication points when putting on or taking off protective clothing, especially with regard to a (time-)efficiently manageable and autonomously achievable possibility of putting on and taking off clothing in an uncomplicated 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 the effective and at the same time comfortable or at least uncomplicated donning of protective clothing, in particular ensuring the sealing of critical transition or connection areas.

[0019] In this context, there is also a particular need to integrate the corresponding transition area or opening area into a

[0020] Protective clothing against entry or penetration or a

[0021] to provide special protection against the penetration of harmful or toxic substances that come into contact with the material, and at the same time to enable the user to put on and take off the protective clothing safely, comfortably and quickly.

[0022] Against this background, the present invention aims to propose an efficient technical solution for providing protective clothing that can be put on in a time-efficient, independent and safe manner and is simultaneously reliable, safe and comfortable to wear, whereby the disadvantages of the prior art described above are to be largely avoided or at least mitigated.

[0023] 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 for civilian and / or military purposes, and which has improved sealing properties against harmful or toxic substances in the transition or connection area of ​​the protective clothing, wherein the transition or connection area is to be sealed against harmful or toxic substances on the one hand, and on the other hand the transition or connection area, or in a broader sense the protective clothing as a whole, is to be designed in such a way that the user can put it on and adjust it safely and comfortably in a time-efficient, safe and uncomplicated manner.

[0024] The measures used to solve the underlying problem according to the present invention should be optimized in terms of process and concept engineering and be universally implementable, and should also enable the production of corresponding protective clothing on an industrial scale.

[0025] To solve the problem described above, the present invention therefore proposes – according to a first aspect of the present invention – protective clothing according to the invention with a protective function against chemical, biological or radioactive pollutants and / or toxins (warning agents), in particular ABC protective clothing, preferably for civilian or military purposes, according to claim 1; further advantageous developments and embodiments of this aspect of the invention are the subject of the corresponding dependent and subsidiary claims relating to the protective clothing according to the invention.

[0033] Having said that, the present invention will now be described and explained in more detail, also with reference to drawings or figures illustrating preferred embodiments or exemplary embodiments.

[0034] 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 harmful and / or toxic substances (warning agents) ("ABC or CBRN protective function"), in particular ABC protective clothing ("CBRN protective clothing"), preferably for civilian 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-layered protective material, wherein the protective material comprises:

[0035] (a) a first layer, in particular planar and / or two-dimensional, in the form of a multi-layered, in particular at least two-layered, 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 comprises an adsorption layer and a textile support layer (“adsorption layer support”), and

[0036] (b) a second layer, in particular a planar and / or two-dimensional layer, in the form of a textile air-permeable outer material (“outer layer”), wherein the protective clothing has an extension section which can be opened and / or closed with at least one closure means for selectively widening and / or increasing the inner and / or outer diameter of the protective clothing in the area of ​​the extension section, wherein the extension section is arranged at least partially, preferably completely, on and / or in the extremity section, and wherein the closure means is connected only and / or exclusively 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 area, in particular using at least one yarn and / or thread.

[0037] The protective clothing according to the invention therefore has at least one extremity section for the, 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 application state, in particular wherein the extremity section surrounds and / or encloses at least one extremity of the wearer at least partially.

[0038] Furthermore, the protective clothing according to the invention comprises a multi-layered protective material. According to the invention, the protective material comprises:

[0039] (a) a first layer, in particular planar and / or two-dimensional, in the form of a multi-layered, in particular at least two-layered, 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 comprises an adsorption layer and a textile support layer (“adsorption layer support”), and

[0040] (b) a second layer, in particular a planar and / or two-dimensional form, in the form of a textile air-permeable outer material (“outer layer”).

[0041] Furthermore, the protective clothing according to the invention has an extension section that can be released and / or closed by at least one fastening means for selectively widening and / or increasing the inner and / or outer diameter of the protective clothing in the area of ​​the extension section, wherein the extension section is arranged at least partially, preferably completely, on and / or in the extremity section. Furthermore, the fastening means is connected only and / or exclusively to the second layer, in particular by sewing, and / or the fastening means is, preferably directly, unconnected to the first layer, in particular wherein the fastening 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.

[0042] A central idea of ​​the present invention is therefore to provide a solution that significantly simplifies the donning and wearing of protective clothing, while maintaining at least the same, and especially improving, its protective performance. This is particularly important with regard to enabling independent, quick, and easy donning of the protective clothing, while simultaneously ensuring the user's safety. The present inventive concept thus represents a particularly well-balanced and user-oriented, as well as application-optimized, solution for protective clothing that allows the user to don the protective clothing in a simplified, quick, and safe manner, without compromising the protective and safety properties of the clothing.

[0043] In this context, it is specifically provided according to the invention that the multi-layered 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 specifically 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, especially in the case that extensive undergarments are worn by the user, and in particular also of adjusting and adapting it easily and precisely 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.

[0044] According to the invention, the user of the protective clothing is thus reliably enabled to autonomously put on the protective clothing completely within a comparatively short time, even if the user is wearing safety footwear, gloves, or rubber overshoes, and then to optimally position, adjust, and adapt the protective clothing in a short time and with simple (and potentially imprecise) manual steps, in particular so that the protective effect of the protective clothing is reliably achieved without impairment. In this regard, the applicant has discovered, quite surprisingly, that a protective clothingcomprising a multi-layered protective material and an extension 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 area of ​​the extension section, wherein the extension section is arranged at least partially, preferably completely, on and / or in the extremity section, and wherein the closure means is connected only and / or exclusively 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 area, in particular using at least one yarn and / or thread, the protective effect of the protective clothing remains in particular unaffected by the extension section or the closure means.especially since the first layer of protective material in the protective clothing, which forms the inner layer, is not structurally and therefore, in particular, functionally affected by the widening section or the closure element.

[0045] Preferably, the closure is not sewn to the first layer. Alternatively or additionally, it is preferably provided that the seam connecting the closure and the second layer, and / or the corresponding seam area, is not connected to the first layer. Accordingly, the first layer is not damaged, perforated, and / or penetrated by the closure or by the connection of the closure to the second layer. The protective effect of the protective material can therefore be guaranteed even with improved positioning of the protective clothing on the wearer's extremities and is not impaired, in particular, by the widening section.

[0046] In this context, it is understood that the feature that the fastening means is connected only and / or exclusively to the second layer is to be understood in particular as meaning that the second layer does not include the first layer, and that the second layer may, in particular, also be multilayered. In the case of a multilayered second layer, the fastening means is particularly preferably connected only and / or exclusively to at least one layer, and in particular to all layers, of the second layer. The second layer is also designed as a textile, air-permeable outer material. This feature is to be interpreted in particular such that at least one layer of the second layer is textile and air-permeable. Further layers of the second layer may—but in particular need not—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.

[0047] Nevertheless, the protective material as a whole, i.e., both the inner and outer layers, can be designed to correspond to the widening section, thus facilitating and simplifying the donning of the protective clothing. In particular, the positioning and adjustment of the protective clothing is also significantly easier and more intuitive and user-friendly due to the inventive design of the widening section. Furthermore, it is ensured that the protective properties of the protective clothing according to the invention are optimally realized, as the inner and outer diameters of the protective clothing can be optimally regulated thanks to the flexibly manageable widening section, especially in a manner tailored to achieving an optimized protective effect.

[0048] This means that, within the scope of the invention, even when wearing full protective equipment, it is still ensured that the user can safely adjust the protective clothing according to the invention, in particular reliably narrowing it in the extremity section 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, especially since, within the scope of the present invention, such inner or outer diameters can also be realized that are usually practically impossible to implement without significantly complicating the putting on of protective clothing, especially when wearing appropriate undergarments or safety shoes or gloves.

[0049] This invention makes it possible to design protective clothing that was previously impossible due to application-specific limitations, such as the need to specify inner or outer diameters for extremity sections. These dimensions must be precisely tailored to allow users, such as those wearing safety shoes, to put on or slip into the protective clothing with sufficient ease. This often results in a relatively large volume of space between the user's body circumference and the protective clothing, increasing the risk of punctures, particularly at transitions or openings in the garment, due to undirected wrinkling caused by excess material in these areas.

[0050] The present invention significantly minimizes such a risk by allowing the widening section to selectively provide and compensate for volume, depending on the application phase of the protective clothing.

[0051] A particularly advantageous aspect of the present invention is that it allows for a defined, predetermined, and user- and application-optimized addition or removal of material surface area or clothing volume, which greatly benefits both application safety and ease of use. Specifically, the present invention eliminates the need for the user—who may be in an exceptional situation—to find a safe and optimized setting for the protective clothing. Instead, the protective clothing itself dictates the degree to which the amount of fabric or clothing volume is added or, more importantly, reduced to ensure optimal application safety. In this respect, the present invention also facilitates the rapid adjustment of the protective clothing.Above all, the probability of user errors when adjusting the clothing is reduced so significantly that the user can be offered increasingly reliable protection overall.

[0052] The present invention thus provides a comprehensive technical solution for realizing protective clothing concepts that were previously impractical due to application-specific limitations. This results in increased user safety and significantly simplified handling. Furthermore, it achieves reliable sealing performance for extremity sections, which are often challenging components of protective clothing. This is accomplished by a defined adjustment mechanism, provided by the protective clothing itself, to ensure a proper seal.After the application of these, the present invention can provide a solution that is easy and safe for the user to handle and reliably implement with regard to the protective effect, increasing the comfort of putting on and wearing protective clothing while simultaneously ensuring the protective effect and user safety, and which is clearly advantageous compared to the prior art.

[0053] The term "seam" used in the context of the present invention is to be understood in particular as a joining of the underlying layers or materials by sewing, wherein at least one yarn or thread is generally used for the seam, which is repeatedly passed through the material being sewn in the form of the second layer or the respective layers, whereby the yarn or thread is connected or interlocked with the material being sewn. Thus, in the context of the seam connecting the second layer and the closure element, it is in particular a yarn- or thread-based seam. Accordingly, the seam in question is particularly preferably not a threadless connection, nor is it an adhesive or welded seam.

[0054] The term "seam area," as used in the context of the present invention, is to be understood in this context as representing a section or area with the overlapping arrangement or positioning of the closure element with the second layer, which is formed by the common seam and the corresponding seam-like engagement or connection of the second layer and the closure element. The seam area thus refers in particular to the area in which the underlying layers to be joined, namely at least the second layer and the closure element, are connected or engaged by the common seam.

[0055] Further advantageous developments and embodiments of this first aspect of the invention are the subject of the corresponding dependent and subsidiary claims relating to the protective clothing according to the invention and are further disclosed below in the description of the figures.

[0056] A further object of the present invention – according to a second aspect of the present invention – is a method according to the invention for manufacturing protective clothing with a protective function against chemical and / or biological and / or radioactive hazardous and / or toxic substances (warning agents) ("ABC or CBRN protective function"), in particular ABC protective clothing ("CBRN protective clothing"), preferably for civilian or military purposes, especially in the form of trousers, a jacket or an overall, preferably in the form of trousers, in particular a method for manufacturing protective clothing as described above according to the present invention, wherein, to form an extremity section, a first layer is formed independently from individual cut pieces of the first layer to be joined together and a second layer is formed independently from individual cut pieces of the second layer to be joined together.wherein the cut pieces of the first layer are joined together to form the first layer, preferably sewn together, and wherein the cut pieces of the second layer are joined together to form the second layer, preferably sewn together, wherein, in particular after formation and / or during the formation of the second layer, a closure means of a widening section is connected only and / or exclusively to the second layer, in particular in at least one seam area by sewing, in particular using at least one yarn and / or thread, and wherein, in particular after the connection of the closure means to the second layer, the first and the second layer are arranged and / or positioned overlapping each other and are connected to each other, in particular in at least one connection area.

[0078] Fig. 18 shows a further schematic perspective view of a part of the protective clothing according to the invention shown in Fig. 15, with a corresponding schematic representation of the material section covering the further fastening means on the upper side in the closed state of the opening section. The figures according to Figs. 1 to 18 particularly illustrate the first aspect of the present invention, namely that, according to the invention, protective clothing 1 with a protective function against chemical and / or biological and / or radioactive hazardous and / or toxic substances (warning agents) ("ABC or CBRN protective function"), in particular ABC protective clothing ("CBRN protective clothing"), is provided, preferably for civilian or military purposes. In particular, the protective clothing 1 is designed in the form of trousers 2, as shown in Figs. 1 to 3.A pair of trousers 3 can include elongated extremity sections 4 designed for arrangement on the legs of a wearer, as shown schematically in Figs. 1 to 3.

[0079] Fig. 7 shows that the protective clothing 1 is also designed in the form of a jacket 3. It is not shown that the protective clothing 1 is also designed in the form of a coverall or pullover.

[0080] The protective clothing 1, as shown in Fig. 1, is particularly preferred in the form of trousers 2.

[0081] As previously explained, Figures 1 to 3 show that the protective clothing 1 has at least one extremity section 4 for the partial and / or complete protection of at least one extremity, particularly at least one upper and / or lower extremity, of a wearer of the protective clothing 1, preferably in the wearing and / or application state. This extremity section 4 is particularly preferably elongated. The longitudinal extension of the extremity section 4 is particularly evident in the longitudinal direction of the respective extremity of the wearer that is to be protected by the extremity section 4.

[0082] In the application and / or use state of the protective clothing 1, it is specifically provided that the extremity section 4 surrounds and / or encloses at least one extremity of the wearer, at least partially. In this context, it is understood that areas of the wearer's extremity may, if necessary, protrude from the extremity section 4 when worn, particularly the hands and / or feet, which can be protected as needed by additional protective equipment, preferably gloves and / or footwear. In particular, a large part of the wearer's extremity, in particular at least 70%, preferably at least 80%, and more preferably at least 85%, is covered by the respective extremity section 4 when worn. The protective clothing 1 shown in Fig. 1 has a multi-layered protective material 5, as is shown in particular for different embodiments in Figs. 8 to 13.

[0083] Fig. 8 shows that the protective material 5 has several layers, namely at least:

[0084] (a) a first layer, in particular a planar and / or two-dimensional layer

[0085] 6 in the form of a multi-layered, in particular at least two-layered, 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 support layer 6b ("adsorption layer support"), and

[0086] (b) a second layer, in particular a planar and / or two-dimensional layer

[0087] 7 in the form of a textile air-permeable outer material ("outer layer").

[0088] The protective clothing 1 proposed according to the invention has an extension section 9 that can be released and / or closed by 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 area of ​​the extension section 9. The extension section 9 is shown in Fig. 2 in the closed state and in Fig. 3 in the released state, which can also be described as, preferably fully, open and / or, in particular, maximally widened. For the purposes of the present invention, the released state of the extension section 9 refers in particular to the maximally widened state in which the closure means 8 has been actuated for maximum release.Preferably, intermediate states can also be assumed, which can also be considered as open - for example, when the locking means 8 has been actuated to half of the widening section 9.

[0089] The widening section 9 shown in the figures is arranged at least partially, preferably completely, on and / or within the extremity section 4. Accordingly, the widening section 9 can be actuated as needed in a manner specified by the user, enabling a defined release or removal of the protective material 5. The widening section 9 offers particular advantages for putting on the protective clothing 1, especially since, when a wearer's extremity is inserted into the extremity section 4, the inner cross-section of this section can be enlarged, particularly by actuating the fastening device 8, which increases the inner and / or outer diameter 10, 11. This facilitates entry into the protective clothing, thereby improving wearing comfort and / or handling.

[0090] At the same time, damage to the protective material 5 during donning of the protective clothing 1 can be prevented, since a sufficiently large 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, such as gloves and / or footwear, which, when worn, should be at least partially arranged inside the protective clothing 1. With the protective clothing according to the invention, contact between the protective equipment components and the protective material 5 can be reduced, and in particular, tearing of the protective material 5 can be prevented.

[0091] Furthermore, the sealing and / or protective effect against toxins and / or pollutants is also improved. According to the invention, the widening section 9 allows for a selectable widening of the inner cross-section in the area of ​​the extremity sections 4, which is particularly necessary for putting on the protective clothing 1. Because the widening section 9 can be brought into a closed state by the closing means 8, this widening can be reversed 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 potential passages for gases and / or pollutants can thus be significantly reduced, thereby increasing the protective effect. This reduction achievable with the present invention surpasses, in particular, measures that only provide very localized orEnables small-area cross-sectional reduction.

[0092] In particular, the protective material 5 can be released or removed in a defined manner by the widening section 9, thereby ensuring an optimal fit for the wearer. This is a fundamental difference from conventional methods of adjusting protective clothing, which often involve the formation of numerous undefined channel areas. These channels can allow harmful and / or toxic substances to penetrate the interior 13 of the protective clothing 1 and can occur when the protective material 5 is compressed in the area of ​​the extremity section 4 without the presence of a widening section 9. Such effects, which compromise application safety, can be minimized or avoided within the scope of the invention.

[0093] Figures 12 to 14 clearly show that the closure means 8 is connected, in particular sewn, only and / or exclusively to the second layer 7. Alternatively or additionally, according to the present invention, the closure means 8 is preferably directly unconnected to the first layer 6.

[0094] In a particularly preferred embodiment, as illustrated, for example, in Fig. 14, the closure element 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. Sewing enables long-term use of the closure element 8 and the widening section 9 and provides a secure and stable connection. Furthermore, the use of external substances, such as adhesives, which may interact with the harmful and / or toxic substances, can be avoided.

[0095] Preferably, the sealing element 8 does not impair the protective and / or adsorption effect of the first layer 6. This is achieved in particular by the fact that the sealing element 8 does not require direct attachment and / or connection to the first layer 6. The seam area 12, which preferably connects the sealing element 8 and the second layer 7, does not extend through the first layer 6, so that the first layer 6 is preferably not perforated by the seam area 12.

[0096] In the wearing and / or application state of the protective clothing 1, the first and second layers 6, 7 lie at least substantially against each other, as shown in Fig. 12. Only in certain connection areas, which are not shown in detail in the figures, particularly in the hem, are both layers 6, 7 connected to each other, in particular sewn. In the other areas, a distance between the two layers 6, 7 can also be achieved, if necessary, by pulling the layers 6, 7 apart, as shown, for example, in Figs. 13 and 14. In particular, both layers 6, 7 can be spaced apart from each other, at least substantially, over the length of the fastening element 8, in particular without the fastening element 8 or the widening section 9 hindering this.In a preferred embodiment of the present invention, the first layer 6 is arranged and / or positioned on the side of the protective clothing 1 facing away from a source of harm and / or toxins when the protective clothing 1 is in its wearing and / or application state.

[0097] 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, when worn and / or used.

[0098] 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 conditions.

[0099] Equally preferably, the second layer 7 is arranged and / or positioned on the side of the protective clothing 1 facing a source of harm and / or toxins, in particular on the outside of the protective clothing 1, when the clothing is worn and / or in use. This is shown schematically in Fig. 1.

[0100] In other words, the second layer 7, when the protective clothing 1 is worn and / or in use, is preferably arranged and / or positioned facing away from the interior 13 of the protective clothing 1, and in particular away from the wearer of the protective clothing 1. As explained above, this arrangement protects the first layer 6 from mechanical stresses caused by the second layer 7.

[0101] Furthermore, this arrangement also allows the fastening device 8 to be positioned on the outside or on the side of the protective clothing 1 facing a source of contamination and / or toxic substances. This ensures that the fastening device 8 is accessible and operable by the wearer of the protective clothing 1 when the clothing is worn.

[0102] Furthermore, the protective clothing 1 is preferably in the form of trousers 2, as shown in Figures 1 to 3. In other words, the protective clothing 1 can be in the form of legwear, in particular in the form of trousers and / or over-trousers. Trousers 3 have, in particular, two elongated leg sections 4 that can be attached to the legs of a wearer.

[0103] In a preferred embodiment not shown in detail, the protective clothing 1 is designed in the form of a coverall, wherein a coverall has four limb sections 4, in particular for the legs and arms of the wearer. A widening section 9 is arranged on at least one of these limb sections 4.

[0104] For a further preferred embodiment, Fig. 7 shows that 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 provided for arrangement on the arms of a wearer.

[0105] It is also not described in detail that in another preferred embodiment of the invention, the protective clothing 1 is designed in the form of a pullover. Like a jacket 3, a pullover can have two extremity sections 4 in which the wearer's arms can be positioned.

[0106] 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, especially at least in the area 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.

[0107] Particularly preferably, at least 70%, preferably at least 80%, and especially preferably at least 85% of the wearer's extremity protected by extremity section 4 are covered, surrounded, and / or enclosed by the extremity section. In this way, the wearer's extremity can be protected, at least substantially, with certainty.

[0108] In general, within the scope of the present invention, it can be provided that the widening section 9 is part of the second layer 7 and / or part of the extremity section 4 and / or can be attributed to it. Most preferably, the widening section 9 is part of the extremity section 4 and comprises the first and second layers 6, 7 containing the protective material 5. Accordingly, the protective effect can also be provided in the widened state of the widening section 9.

[0109] Furthermore, as also illustrated in Fig. 1, the invention provides that the widening section 9 and / or the fastening element(s) 8 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 ensures that the fastening means 8 and / or the fastening element 8 are protected in the wearing and / or application state and, in particular, do not impair the arrangement of other equipment items and / or pockets.

[0110] According to this embodiment of the present invention, which is generally described 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, the inner region or the inner area of ​​the extremity section 4 is, in particular, that section of the extremity section 4 which faces the other extremity of the wearer.

[0111] In this regard, it can also be provided that the widening section 9, the closure element 8, and / or the inner area or region of the extremity section 4 is arranged and / or positioned on the inner side of the leg, preferably at least on the inner side of the lower leg, and / or on the inner side of the arm, preferably at least on the inner side of the forearm, of the wearer of the protective clothing 1, and / or faces them. As explained above, this arrangement allows the widening section 9 to be protected and further optimizes the positioning of additional equipment, pockets, or the like.

[0112] According to a first, preferred embodiment according to the invention (as also referred to in Fig. 1), it can generally be provided according to the invention that the extremity section 4 is designed as trouser section 14, in particular as trouser leg of the trousers.

[0113] Not shown in detail, the extremity section can preferably also be designed as trouser section 14 of the overall. In the preferred embodiment shown in Fig. 7, the extremity section 4 is designed in particular as sleeve section 15, especially as sleeve of the jacket 3, the overall and / or the pullover.

[0114] The aforementioned extremity sections 4 are subject to particularly high demands regarding tightness when using protective clothing 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 protective clothing.

[0115] In this context, Fig. 1 also illustrates the preferred embodiment according to the invention, in which the protective clothing 1 has at least two extremity sections 4, and particularly preferably at least two extremity sections 4 designed as trouser sections 14, especially as trouser legs. This embodiment, particularly with the widening section 9 arranged on both trouser sections 14, ensures that the wearer's legs are reliably protected from the penetration of harmful and / or toxic substances into the interior 13 of the protective clothing 1 during use.

[0116] Fig. 7 shows that in a further preferred embodiment, at least two extremity sections 4, designed as sleeve sections 15, are particularly preferably provided. In particular, widening sections 9 are provided on both sleeve sections 15 of the protective clothing 1, which improve both handling and protection for the respective extremity.

[0117] Accordingly, as previously described, the widening section 9 is preferably arranged on at least two extremity sections 4 of the protective clothing 1, as illustrated in Fig. 1. Fig. 1 shows that 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.In this context, according to the invention, it can be provided in particular that the widening section 9 extends from an open end 16 of the extremity section 4, in particular the trouser section 14, preferably the trouser leg, as shown in Fig. 1, and / or the sleeve section 15, preferably the sleeve, as shown in Fig. 7. It is further preferred in this context that the widening section 9 extends in the longitudinal direction L of the extremity section 4, as is also illustrated in Fig. 1.

[0118] In this regard, it can also be provided that the widening section 9 tapers upwards, particularly away from the open end 16 of the extremity section 4, as shown schematically in Figures 3 and 4. A tapered design allows, firstly, optimized folding and / or compression of the protective material 5 of the widening section 9. Secondly, the operability and / or handling of the widening section 9 or the closure device 8 can be improved, since, in particular, correct positioning of the material of the widening section 9 before actuating the closure device 8 is not necessary. Specifically, the widening section 9 tapers from the open end 16 of the extremity section 4 in the longitudinal direction L of the extremity section 4.

[0119] A further advantage of the tapering of the extremity section 4 is that, if necessary, the extremity section 4 itself can also taper towards the open end 16 and thus better adapt to the shape of the respective extremity.

[0120] According to this embodiment of the present invention, which is shown in particular in Fig. 2 and Fig. 3, it can also be provided that the widening section 9 can be converted by the closing means 8 into a selectively released, preferably widened and / or open, or closed state.

[0121] In principle, intermediate states of the widening section 9 can also be reached by actuating the locking device 8, in which the locking device 8 has not been actuated to its maximum release. These states of the widening section 9 can be described in particular as partially released, preferably partially released and / or partially open, states of the widening section 9. These states also correspond in particular to a partially closed widening section 9 and can thus, in other words, also be described in particular as partially closed states of the widening section 9.

[0122] Figure 3 schematically illustrates that, in a preferred embodiment of the present invention, the widening section 9, particularly in both the closed and released states, and preferably in the widened and / or open state, comprises a closed, in particular continuous, and / or contiguous surface of the first layer 6 and / or the second layer 7, without any openings. Unlike a zipper, for example, in a trouser fly, the closure means 8 does not divide two parts of the protective material 5 separated from each other by an opening. In this way, the widening section 9, particularly in every state, comprises a continuous protective material 5, and thus the protective effect is preferably not impaired by any openings, holes, or the like that may be formed in the protective material 5 during use and / or application.

[0123] In other words, at least the first layer 6 in the widening section 9 is, in particular, uninterrupted and / or continuous in the closed and / or open or released state, especially 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 openings in the widening section 9, especially in every state of the widening section 9, thereby ensuring good protection, especially for the wearer's extremities.

[0124] In this context, it is particularly important to understand that the feature that the first layer in the widening section 9 is continuous and / or uninterrupted does not preclude the presence of perforations in any intended connection areas and / or seam areas of individual sections of the first layer 6 or in the connection area to the second layer 7. These perforations would be present anyway and are not, and in particular will not be, affected by the widening section 9.

[0125] Figure 6 shows a particularly preferred embodiment in which the widening section 9, when closed, has at least one fold 17 arranged and / or formed inside 13 of the protective garment 1 and / or a fold 17 facing inwards towards the wearer of the protective garment 1, with at least two fold legs 18 of the protective garment 1. The fold 17 enables, in particular, efficient compression and / or folding or stowing of the protective material 5 when the widening section 9 is closed. Thus, the fold 17 can ensure, in particular, that the protective material 5, when closed, does not impair wearing comfort through bothersome bulges.In the same way, damage to the protective material 5 can be prevented both in the closed state and when the locking device 8 is actuated, since the protective material 5 is assigned a specific space by the formation of the fold 17, which in particular does not make the actuation of the locking device 8 more difficult, for example by means of a snagging.

[0126] For a further preferred embodiment, as shown in Fig. 3, it is provided that a side seam 40, in particular a trouser side seam, connecting at least two cut pieces of the second layer 7 together, in particular sewing them together, preferably extending 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 in the middle of the widening section 9.

[0127] It is not shown in detail that side seam 40 can also be a sleeve side seam.

[0128] The term "cutouts" of the first and / or second layer 6, 7 is to be understood as meaning that, in particular, the first and / or second layer 6, 7 are composed of parts or sections, these parts or sections being referred to as "cutouts" within the meaning of the present invention. Cutouts of the first and / or second layer are, in the wearing and / or use state, in particular connected to one another, preferably sewn. A plurality of cutouts can be provided for both the first layer 6 and the second layer 7. Ultimately, the first layer 6 can be formed by joining the cutouts of the first layer 6. Similarly, the second layer 7 can be formed, in particular, by joining the cutouts of the second layer 7.

[0129] Advantageously, in this preferred embodiment of the present invention, when the widening section 9 is closed, 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 located anyway without a widening section 9. A further advantage is that, when the widening section 9 is closed, the side seam 40 is located 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 therefore be further reduced.

[0130] In Fig. 6, a particularly preferred embodiment is shown in which the fold legs 18 of the fold 17 are separated from each other by the side seam 40 in the closed state of the widening section 9.

[0131] This makes it possible, in particular, for the fold 17 to be predefined and / or determined by the side seam 40, so that, especially without the need for time-consuming manual folding of the fold 17 by the wearer, the fold 17 can form "automatically," and the fold legs 18 can be easily defined in this way. This leads, in particular, to simplified handling of the protective clothing 1, especially when putting it on.

[0132] In another preferred embodiment, Fig. 4 schematically illustrates that the widening section 9 is wedge-shaped in the open state. The wedge shape of the widening section 9 increases the wearing comfort of the protective clothing 1 and, in particular, simplifies the folding of the pleat 17 and / or the protective material 5 when closing the widening section 9. Furthermore, the wedge shape provides an extension in that section of the extremity section 4 which should be as wide as possible, especially when putting on the protective clothing 1, but should be reduced as much as possible during use and / or application. This applies particularly 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, to accommodate 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 ingress of toxic and / or harmful substances. Within the scope of the invention, these diametrically opposed requirements can therefore be met in a particularly advantageous manner.

[0133] Figure 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 are formed as wedge-shaped fold 17 and / or as wedge-shaped fold legs 18. The fold 17 and the fold legs 18 are not visible in detail in Figure 5, as the widening section 9 is shown in the closed state. However, the wedge shape is schematically indicated by a dashed line.

[0134] Figure 4 further illustrates that the closure element 8 preferably terminates at and / or in the region of the tapered end 19 of the widening section 9, particularly in the open and / or closed state of the widening section 9. The wedge shape of the widening section 9 can therefore also define the path of the closure element 8 and thus, particularly at the tapered end 19, ensure that no material preferably becomes entangled in the closure element 8 at its end when the widening section 9 is fully open.

[0135] An angle oc, as shown schematically in Figures 3 and 4, at the tapered end 19 of the wedge-shaped widening section 9, particularly when the widening section 9 is open, of at least 3°, preferably at least 5°, more preferably at least 10°, and / or of 3° to 70°, more preferably from 5° to 40°, more preferably from 10° to 25°, has proven particularly advantageous. The aforementioned angles a enable an improved design of the widening section 9.

[0136] Figure 3 illustrates that, in a further preferred embodiment, the locking means 8 extends at least substantially over the entire length, particularly in the longitudinal direction L of the extremity section 4, of the widening section 9. Consequently, the widening section 9 does not protrude from the locking means 8. In this way, the entire widening section 9 can be actuated by the locking means 8.

[0137] In a particularly preferred embodiment, 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%, and in particular at least 20%, of the length of the extremity section 4, especially in the longitudinal direction L of the extremity section 4. In this way, an elongated extremity section 4 is obtained, which can be used to cover the extremity of a wearer and can therefore adapt to the elongated shape of the wearer's extremity, thus ensuring optimal protection.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 the length of the extremity section 4, particularly in the longitudinal direction L of the extremity section 4, being between 5% and 60%, preferably between 10% and 40%, more preferably between 15% and 35%, and in particular between 20% and 30%.

[0138] Figure 3 shows that, in the preferred embodiment depicted therein, the maximum width of the extremity section 4 in the released state, preferably in the widened and / or open state, corresponds to at least 6%, preferably at least 12%, more preferably at least 18%, and in particular at least 23%, of the length of the extremity section 4, particularly in the longitudinal direction L of the extremity section 4. This allows, in particular, the opening cross-section or the inner and / or outer diameter 10, 11 of the extremity section 4 to be sufficiently enlarged to improve handling, and the protective clothing 1 to be put on easily and quickly, even with footwear and / or gloves on.

[0139] 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 be between 6% and 65%, preferably between 12% and 45%, more preferably between 18% and 40%, in particular between 23% and 33%, corresponding to the length of the extremity section 4, in particular in the longitudinal direction L of the extremity section 4.

[0140] In a particularly preferred embodiment, the closing means 8 extends continuously and / or without interruption over the entire length of the widening section 9 and / or is designed as a continuous or uninterrupted closing means 8, as shown schematically in particular in Fig. 3.

[0141] In particular, the closure means 8 is designed as a zipper 20, as can be seen schematically in Fig. 4. The zipper 20 allows for simple operation with minimal user error, and is further characterized by its durability and secure closure. Preferably, the zipper 20 has two side parts 21, in particular having prongs, and a slider 22 that selectively connects the side parts 21 via a positive locking mechanism. In particular, the side parts 21 of the zipper 20 can define the widening section 9, as shown schematically in Fig. 3.

[0142] Figure 6 illustrates particularly clearly that in a further preferred embodiment, the closure element 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 preferably firmly connected to the protective material 5, in particular the second layer 7, especially by sewing. In this way, the functionality of the protective material 5, the first and the second layers 6, 7 is not impaired, and simple adaptation of the closure element 8 is also ensured.

[0143] Preferably, the closure element 8 is not encased or not encased and / or not inserted or connected to the second layer 7 and / or arranged on the second layer 7. Consequently, the functionality of the closure element 8 is also not impaired.

[0144] Figure 4 shows that the fastening means 8, in particular the zipper 20, preferably has at least two fastening elements 23, in particular side parts 21, which can be connected to each other, preferably in a form-fitting manner. The fastening elements 23 enable the extension section 9 to be limited and also ensure the secure closure of the extension section 9 in the closed state. The fastening elements 23 can be designed, at least in some areas, in a complementary manner to each other and thus ensure multiple actuations of the fastening means 8.

[0145] Figure 2 shows a further preferred embodiment in which the fastening elements 23, in particular the side parts 21, of the fastening means 8 are sewn to the second layer 7, preferably only and / or exclusively, by at least one seam area 12. Consequently, the seam area 12 does not impair the protective effect of the first layer 6 and / or the first layer 6 as such. Figure 3 schematically illustrates that the widening 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 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 therefore be provided over a large part of the length of the extremity section 4, after which the previously described advantages of the easy handling of the protective clothing 1 can follow.

[0146] In other words, the widening section 9 can extend over a range of 40% to 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 sleeve section 15, preferably the sleeve.

[0147] 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 at least 5%, more preferably at least 5%, and in particular at least 10%. The aforementioned widening allows, in particular, the wearer's extremities to easily slide into the extremity sections 4 when putting on the protective clothing 1.

[0148] 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%.

[0149] In further embodiments, the limb section 4, in particular the trouser section 14, preferably the trouser leg, and / or the sleeve section 15, preferably the sleeve, can be designed at least substantially tubular, and in particular at least substantially cylindrical, at least in the area of ​​the widening section 9 when the widening section 9 is closed. It is particularly preferred in this context that the width of the limb section 4, in particular the trouser section 14, preferably the trouser leg, and / or the sleeve section 15, preferably the sleeve, when the widening section 9 is closed, preferably across and / or in the longitudinal direction L of the limb section 4, be at least substantially the same.

[0150] According to a further preferred embodiment, as schematically shown in Fig. 2, the extremity section 4, in particular the trouser section 14, preferably the trouser leg, is designed to taper towards the open end 16 of the extremity section 4, at least in the area of ​​the widening section 9 when the widening section 9 is closed, particularly in the longitudinal direction L of the extremity section 4. In this way, the fit of the extremity section can be improved, especially when the widening section 9 is closed, since the tapered extremity section 4 can adapt to a tapered limb of the wearer, thereby ultimately improving the protective effect against harmful and / or toxic substances when protective clothing 1 is worn.

[0151] Figure 7 schematically illustrates that preferably the sleeve section 15, or more preferably the sleeve itself, is also designed to taper towards the open end 16 of the extremity section 4, at least in the area of ​​the widening section 9, when the widening section 9 is closed, particularly along the longitudinal direction L of the extremity section 4. This can result in the advantages described above.

[0152] In this context, it is particularly preferred if the minimum width of the limb section 4 in the tapered area of ​​the limb 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 limb section 4 in the tapered area of ​​the limb section 4.

[0153] Figures 2 and 3 schematically show that preferably inside 13 of the protective clothing 1, in particular inside 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.

[0154] The gaiter 4 ensures that the protective clothing 1 does not shift and / or slip, particularly when the protective clothing 1 is being worn and / or used. The gaiter 4 can preferably also be connected to external equipment, such as footwear, and in this way, in particular, position the extremity section 4 relative to the footwear.

[0155] Furthermore, when donning 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 insertion, especially when protective equipment is already in place, into the extremity section 4.

[0156] The comfort of wearing the protective clothing 1 can also be improved by the gaiter 24, in particular by ensuring that the gaiter 24 and not the first layer 6 is adjacent to the wearer's extremity.

[0157] In particular, the gaiter 24 is connected, especially by stitching, to at least the first layer 6, and in particular only and / or exclusively to the first layer 6. This allows the gaiter 24 to be arranged internally, with only a small section protruding from the extremity section 4 when in use.

[0158] In this context, it is particularly preferred that the gaiter 24 extends at least over the length of the widening section 9. The protective clothing 1 can therefore be positioned by the gaiter 24 in both the open and closed states of the widening section 9.

[0159] Particularly preferred in this context is that the opening width of the gaiter 24 corresponds at least substantially to and / or exceeds the opening width of the extremity section 4, preferably the trouser section 14, preferably the trouser leg, and in particular the inner diameter 10 of the extremity section 4, preferably the trouser section 14, preferably the trouser leg, in the released state, preferably in the widened and / or open state, of the widening section 9, as is clearly shown in Fig. 3. The gaiter 24 therefore does not present any further obstacle when inserting the wearer's extremities into the respective extremity sections 4 and consequently does not impair the achievement of the advantages of the widening section 9 according to the invention as described above.

[0160] In this context, it is advantageous that the opening cross-section of the gaiter 24 can be reduced by means of a fastening element 25. The fastening element 25 can, in particular, include an elastic band and a locking element for securing or releasing the elastic band as needed. The fastening element 25 enables the gaiter 24 to be fixed in place during use. The fastening element 25 can also have a barrier effect, which is particularly advantageous in combination with the widening section 9 and allows for an enhanced barrier effect against the ingress of contaminants.

[0161] Figure 15 shows a further preferred embodiment in which the protective clothing 1 has at least one opening section 27, in particular a fly, which can be released and / or closed by a further fastening means 26, for selectively opening the protective clothing 1 in the area of ​​the opening section 27. The opening section 27 allows for a further simplified donning of the protective clothing 1, which, depending on the fit, requires the opening section 27 to be released as needed.

[0162] It is not shown in detail that the opening section is and / or forms a divisible opening section 27 of a jacket 3, a sweater or an overall.

[0163] The opening section 27 can be particularly protected according to the invention, as is described below:

[0164] In this context, the additional closure element 26, when closed, can be covered and / or concealed on its underside and / or on its side facing the interior 13 of the protective clothing 1 and on its upper side and / or on its side facing the source of the harmful substance and / or toxin, each with a material section 28a, 28b of at least the first layer 6, in particular with a material section 28a, 28b of the protective material 5. This arrangement enables, in particular, at least "double protection", namely protection on the upper and lower sides of the additional closure element 26 when the opening section 27 is closed, as is shown schematically in Fig. 17, which illustrates this particularly clearly. It is especially preferred in this context that the additional closure element 26 is liquid-repellent, preferably water-repellent, in particular waterproof, and / or airtight or windproof.This provides further protection for the carrier in the area of ​​the additional closure means 26, whereby, combined with the upper and lower arrangement of the respective material sections 28a, 28b, a "triple protection" of the additional closure means 26 can be ensured.

[0165] In addition to the widening section 9, the opening section 27 creates a user-friendly and safer protective garment 1, characterized by its effective donning, yet without any reduction in protective effect during use. Thus, the opening section 27 and the widening section 9 have a synergistic effect, providing an overall efficient protective garment 1.

[0166] Preferably, in this context, the further locking means 26 generally comprises at least two further locking elements 29 that can be connected to one another, preferably in a form-fitting manner. The further locking elements 29 can, in particular, be designed to be complementary to one another in certain areas and, in particular, ensure a form-fitting connection of the further locking means 26.

[0167] The further closure means 26 is particularly preferably designed as a further zipper 30, preferably wherein the further zipper 30 has two side parts 31, in particular having prongs, and a slider 32 which selectively connects the side parts 31 by means of a positive fit, as shown schematically in FIGS. 15, 16 and 18. Preferably, the side parts 31 of the further zipper 30 define the opening section 27.

[0168] Figure 16 shows that the protective clothing 1 has and / or forms an opening 33 when the opening section 27 is open. In particular, when the opening section 27 is open, two sections of the protective clothing 1, each with a further closure element 29 of the further closure means 26, are spaced apart from each other and / or these sections are separated from each other, as shown schematically in Figure 16.

[0169] The opening 33 allows the protective clothing 1 to be widened for putting on the protective clothing 1. In Fig. 16 it is further shown that at least one material section 28a designed as a lower cover section 34 is arranged on at least one subsection of the protective clothing 1, whereby in particular the protection of the opening section 27 shown above can be achieved.

[0170] Furthermore, it is also provided in this context that the lower cover section 34 protrudes from the subsection on which the lower cover section 34 is arranged.

[0171] Furthermore, the lower cover section 34 can, at least partially, preferably completely, cover and / or overlap the further closure element 26 on the side facing the wearer of the protective clothing 1 when the further closure element 26 is closed. This arrangement also results in the protective effect described above by the material section 28a.

[0172] In this context, it is particularly preferred that the further closure means 26 is covered and / or covered on its upper side, in particular on one side of the protective clothing 1 facing the source of the harmful substance and / or toxic substance, at least partially, preferably completely, by a material section 28b designed as an upper cover section 35 when the further closure means is closed, as shown schematically in Fig. 15.

[0173] The upper cover section 35 can be arranged on at least one subsection of the protective clothing 1, in particular on the subsection of the protective clothing 1 on which the lower cover section 34 is also arranged, as also shown in Fig. 15. Both material sections 28a, 28b can therefore be arranged on the same subsection, thus simplifying the donning of the protective clothing 1 and optimizing its protective effect.

[0174] Fig. 15 further shows that preferably the upper cover section 35 protrudes from the section on which the upper cover section 35 is arranged, thus extending the protected area even when the opening section 27 is partially opened.

[0175] It is particularly preferred that the further closure means 26 be liquid-repellent, preferably water-repellent, in particular waterproof, and / or airtight or windproof, which improves the protective effect, as previously explained. In this context, the further closure elements 29, in particular the side parts 31, of the further closure means 26 may preferably have at least partially, preferably completely, a plastic coating and / or plastic film, preferably a polyurethane coating and / or a polyurethane film, particularly on the side of the protective clothing 1 facing the source of the harmful substance and / or toxic substance, and / or be formed at least partially, 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 further sealing agent 26 and consequently further improves the protective effect of the entire protective clothing 1.

[0176] According to the invention, the adsorption layer 6a can be discontinuous and / or gas-permeable.

[0177] In a further particularly preferred embodiment of the present invention, it is provided that the adsorption layer 6a is connected to the textile support layer 6b via an adhesive layer 36 applied to one side of the textile support layer 6b.

[0178] In particular, the adhesion promoter layer 36 can fix and / or cause the adsorption layer 6a to adhere.

[0179] Furthermore, the adhesive layer 36 can be in the form of a water vapor and / or gas permeable and / or discontinuously formed adhesive layer, preferably based on an adhesive polymer.

[0180] Advantageously, the adhesive layer 36 enables or facilitates a bond with the adsorption layer 6a that withstands, in particular, the long-term use of the protective clothing 1 and, moreover, is optimally designed, especially with regard to the protective effect of the protective material 5, preferably through its discontinuous structure. 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.

[0181] In a particularly preferred embodiment, the first layer 6 is gas-permeable, in particular air-permeable, and / or is designed as such. In particular, the first layer 6 may be designed as a gas-permeable, in particular air-permeable, preferably textile, sheet structure.

[0182] In this context, the textile support layer 6b can be present and / or designed as a preferably gas-permeable, in particular air-permeable, textile surface structure.

[0183] In general, it may also be provided in this context that the textile carrier layer 6b is designed as a knitted fabric, in particular as a knitted fabric, woven fabric, nonwoven fabric or textile composite, in particular as a knitted fabric.

[0184] Furthermore, according to a preferred embodiment, it can be provided that the 2 2 textile carrier layer 6b has a basis weight in the range of 10 g / m² to 350 g / m², 2 2 in particular in the range of 20 g / m² to 300 g / m², preferably in the range of 30 g / m² to 250 g / m², particularly preferably in the range of 50 g / m² to 175 g / m², in particular determined according to DIN EN 12127, preferably after 24 hours of air conditioning at a temperature of 20 °C and a relative humidity of 65%.

[0185] Furthermore, with regard to the adsorption layer 6a of the first layer 6, the following embodiments have proven to be particularly advantageous within the scope of the present invention. In particular, it is provided according to the invention that the adsorption layer 6a is discontinuous. Specifically, the adsorption layer 6a is gas-permeable, preferably air-permeable.

[0186] As illustrated in the enlarged detail in Fig. 8 and furthermore in Figs. 9 to 13, it is particularly intended that the adsorption layer 6a comprises or is formed from adsorber particles 6c, in particular a plurality of individual and / or discrete adsorber particles 6c. According to the invention, the first layer 6 is structured as at least two layers (see, for example, Fig. 8 and Fig. 13). Fig. 8 illustrates a two-layer structure of the first layer 6, while Figs. 9 to 13 illustrate three-, four-, and five-layer structures. In a further, also preferred, and 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 structure.

[0187] In general, the adsorber particles 6c of the adsorption layer 6a can be selected from the group of

[0188] (i) in particular particulate activated carbon and / or activated carbon particles, preferably in the form of granular activated carbon particles (“granular carbon”) or spherical activated carbon particles (“spherical carbon”);

[0189] (ii) Zeolites, in particular natural and / or synthetic zeolites;

[0190] (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;

[0191] (iv) Metal oxide and / or metal particles;

[0192] (v) ion exchange resins, in particular polydisperse and / or monodisperse cation and / or anion exchangers, especially of the gel type and / or macroporous type;

[0193] (vi) inorganic oxides, in particular silicon dioxides, silica gels and / or aluminium oxides;

[0194] (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;

[0195] (viii) mineral granules;

[0196] (ix) Clathrats; as well as

[0197] (x) mixtures and / or combinations thereof; wherein (i) is particularly preferred.

[0198] In particular, the adsorber particles 6c of the adsorption layer 6a can be activated carbon particles, preferably in the form of granular activated carbon particles (“granular carbon”) or spherical activated carbon particles (“spherical carbon”), preferably in the form of spherical activated carbon particles.

[0199] According to the invention, it can also be provided that the adsorber particles 6c of the adsorption layer 6a are activated carbon fibers or activated carbon filaments in the form of an activated carbon fiber sheet structure. In this context, the specific configuration of the adsorber particles 6c, preferably in the form of activated carbon particles in granular or spherical form, can be as follows according to the invention:

[0200] - In this context, the diameter of the adsorber particles 6c, in particular the activated carbon particles, can be 0.005 mm to 2.5 mm, preferably 0.01 mm to 2 mm, more preferably 0.015 mm to 1.5 mm, particularly preferably 0.02 mm to 1.25 mm, and most preferably 0.03 mm to 1 mm, and / or wherein the mean diameter, in particular the mean diameter D50, of the adsorber particles 6c, in particular the activated carbon particles, can be 0.01 mm to 2 mm, in particular 0.02 mm to 1.75 mm, more preferably 0.03 mm to 1.5 mm, more preferably 0.04 mm to 1.25 mm, and most preferably 0.04 mm to 1 mm.

[0201] - In addition, the adsorbent particles 6c, especially the activated carbon particles, can be used in a quantity in the range of 5 g / m³ 2 up to 300 g / m² 2 , especially 25 g / m² 2 up to 275 g / m² 2 , preferably 30 g / m² 2 up to 250 g / m² 2 , preferably 50 g / m² 2 up to 200 g / m² 2, are used and / or the protective material 1, in particular the adsorption layer 6a, the adsorber particles 6c, in particular the activated carbon particles, can be used in an amount in the range of 5 g / m² 2 up to 300 g / m² 2 , especially 25 g / m² 2 up to 275 g / m² 2 , preferably 30 g / m² 2 up to 250 g / m² 2 , preferably 50 g / m² 2 up to 200 g / m² 2 exhibit.

[0202] - In addition, the adsorbent particles 6c, in particular the activated carbon particles, can be obtained by carbonization and subsequent activation of a synthetic and / or non-natural product-based particulate starting material, in particular based on organic polymer particles.

[0203] - Preferably, the adsorbent particles 6c, in particular the activated carbon particles, can be obtained from a particulate starting material based on organic polymers, in particular based on sulfonated organic polymers, preferably based on divinylbenzene-crosslinked polystyrene, preferably based on styrene / divinylbenzene copolymers, in particular by carbonization and subsequent activation of the starting material, in particular wherein the content of divinylbenzene in the starting material is in the range of 1 wt.% to 20 wt.%, in particular 1 wt.% to 15 wt.%, preferably 1.5 wt.% to 12.5 wt.%, preferably 2 wt.% to 10 wt.%, based on the starting material.

[0204] Furthermore, it can be provided that the adsorber particles 6c, in particular the activated carbon particles, are based on a polymer-based spherical activated carbon (PBSAC) and / or that the adsorber particles 6c, in particular the activated carbon particles, are formed from a polymer-based spherical activated carbon (PBSAC). Figures 11 and 13 show preferred embodiments of the invention, in each of which the first layer 6 additionally comprises a cover layer 37, in particular arranged on and / or connected to the adsorption layer 6a. The cover layer 37 is particularly preferably in the form of a preferably gas-permeable textile surface and / or is designed as such.

[0205] The cover layer 37 can also 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 when the protective clothing 1 is worn or in use), as shown schematically in Fig. 13. Fig. 11, however, shows another preferred embodiment in which a particle and / or aerosol layer 39, which will be discussed in more detail below, forms the outer layer of the first layer 6.

[0206] Figure 13 schematically illustrates the application of the protective material 5, in which, except in any connection areas, particularly in seams or seam regions, a gap can be maintained between the first layer 6 and the second layer 7. This gap is shown schematically in Figure 13. Such a gap can also be maintained, particularly in the areas of layers 6 and 7 that are not directly connected, for the layer structures of the protective material 5 shown in the further figures.

[0207] The covering layer 37 can therefore protect the adsorption layer 6a from damage, especially from mechanical forces. In this way, the long-term use of the protective clothing 1 with a high level of protection against toxins and / or pollutants can be enabled.

[0208] In a further preferred embodiment, each of which is shown schematically in Figures 1 to 3, the protective clothing 1 has an adjusting means 38 in and / or on the extremity section 4, in particular in the lower area facing the open end 16 of the extremity section 4, for variably adjusting the inner and / or outer diameter 10, 11 of the

[0209] The limb section 4, particularly in the area of ​​the adjustment means 38, is preferably designed to fit snugly against the extremities and / or against other articles of clothing, especially footwear and / or gloves, in the area of ​​the wearer's extremities. 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 Figures 1 to 3. In addition to the defined or predetermined widening and narrowing of the inner cross-section in the limb section 4 by the widening section 9, the adjustment means 38 provides an additional variable adjustment of the limb section 4 for a snug fit against the wearer's extremities.In particular, the adjusting means 38 is only actuated once the protective clothing 1 has been put on and the widening section 9 has been moved into the closed position. Fine adjustments can then be made using the adjusting means 38. In this embodiment of the invention, the wearer of the protective clothing 1 is thus given the opportunity to optimally adapt the protective clothing 1 to their body shape, with the widening section 9 according to the invention particularly improving wearing comfort and the ease of putting on the protective clothing 1.

[0210] In the context of the present invention, it is particularly preferred if the widening section 9 is combined with the adjusting means 38 and the fastening means 25, if a gaiter 24 is provided, as a measure for the efficient and secure adjustment of the protective clothing 1 according to the invention. In this way, three different means are provided in the protective clothing 1 according to the invention, each with its own distinct and complementary effects. These means allow for quick and easy donning of the protective clothing 1 and, in particular, also for quick, individual, and precise adjustment of the protective clothing, which is essential to ensure the best possible protective effect of the protective clothing 1. In this respect, there is a synergistic effect of the various fastening and adjusting means, which is significantly beneficial to the protective clothing 1 according to the invention as a whole.

[0211] Furthermore, Figures 10 and 11 illustrate embodiments according to the invention, in which the first layer 6 additionally comprises a particle and / or aerosol filter layer 39, preferably a particle and aerosol filter layer 39.

[0212] Fig. 11 shows that in a preferred embodiment, the particle and / or aerosol filter layer 39 is arranged on the cover layer 37 and / or connected to the cover layer 37. Fig. 10 shows a further embodiment in which, in particular, the particle and / or aerosol filter layer 39 is arranged on the adsorption layer 6a and / or connected to the adsorption layer 6a.

[0213] Based on this, 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 measure according to the invention, the adsorption layer 6a is further relieved and thus does not become exhausted as quickly. This allows the service life or wearing time of the protective clothing 1 according to the invention to be extended further.

[0214] In this context, the particle and / or aerosol filter layer 39 can be a gas-permeable textile surface structure comprising or formed from a multitude of individual textile fibers. Furthermore, the particle and / or aerosol filter layer 39 can have or consist of at least one functional layer with particle and / or aerosol filter properties, in particular with particle and aerosol filter properties.

[0215] In the context of the present invention, the particle and / or aerosol filter layer 39, if present, is generally arranged or positioned in front of the adsorption layer 6a in the direction of a pollutant or toxic substance source, and thus, in particular, on the side or surface of the adsorption layer 6a facing away from the wearer or user of the protective clothing 1. This relieves the adsorption layer 6a of the burden of absorbing pollutants or toxic substances, since a large proportion of these can already be absorbed by the particle or aerosol filter layer 6e.

[0310] Further embodiments, modifications, variations, special features and advantages of the present invention are readily apparent and achievable for the person skilled in the art when reading the description, without leaving the scope of the present invention.

[0311] The present invention is illustrated by the following exemplary embodiments, which, however, are in no way intended to limit the present invention. EXAMPLES OF EMBODIMENT:

[0312] 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 regard to bis[2-chloroethyl]sulfide (= mustard gas or HD). This method determines the barrier effect of protective clothing or protective material against mustard gas, whereby the quality of the protective function or barrier effect increases with decreasing penetration values.

[0313] In particular, this determination method involves a so-called convective flow test with mustard gas; for this purpose, an airflow containing mustard gas is directed onto 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 pl HD / 12.56 cm²).2 )

[0314] According to the applicant's specifications, the barrier effect against mustard gas, determined according to method 2.2 of CRDEC-SP-84010, should be less than 4 pg / cm². 2 per 24 hours.

[0315] First, a multilayer protective material (i.e., protective material 5 according to Fig. 10), which is known per se and described in detail above, is used according to the invention. This multilayer protective material, as shown in Fig. 10, comprises, on the one hand, an air-permeable, multilayer adsorption filter material acting as an inner layer for the adsorption of chemical and / or biological and / or radioactive pollutants and / or toxins (= 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 treated to be oleophobic and hydrophobic by means of an impregnation. The adsorption filter material ("first layer 6" according to Fig. 10) itself is also multilayered and comprises, viewed from the inside out (i.e., from the support to the outside), a textile support layer or a textile adsorption layer support (reference numeral no. 1).6b according to Fig. 10), on which a multitude of adhesive (polymer) dots (reference numeral no. 36 according to Fig. 10) are applied, distributed across the textile carrier layer in a grid pattern. Discrete adsorber particles (reference numeral no. 6c according to Fig. 10) in the form of activated carbon spheres are permanently fixed or bonded to these dots, forming the adsorption layer (reference numeral no. 6a according to Fig. 10). A textile particle and aerosol filter layer (reference numeral no. 39 according to Fig. 10) is applied or fixed (i.e., by lamination) to the activated carbon spheres or the adsorption layer as a cover layer to further enhance the protective function against pollutants and toxins. This results in a multi-layered, air-permeable protective material (i.e., protective material 5 according to Fig. 10) in the form of a laminate.

[0316] Characterization of the materials used for the multi-layered protective material

[0317] Multilayer adsorption filter material (= first layer 6 according to Fig. 10):

[0318] 2

[0319] • textile carrier layer 6b: textile knit fabric, basis weight approx. 80 g / m² (determined according to DIN EN 12127 after 24 hours of air conditioning at a temperature of 20 °C and a relative humidity of 65 %);

[0320] • Adhesive (polymer) 36: Polyurethane (PU), application rate approx. 35 g / m² 2 , surface of the carrier layer 6b covered with adhesive (polymer) to less than 40%;

[0321] • 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 rate: approx. 90 g / m² 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);

[0322] • Particle and aerosol filter layer 39: gas-permeable textile surface structure (non-woven) made of numerous individual synthetic textile fibers with fiber diameters in the range of 50 nm to 10 pm, basis weight of approx. 50 g / m² 2 (determined according to DIN EN 12127 after 24 hours of air conditioning at a temperature of 20 °C and a relative humidity of 65%).

[0323] Outer material (= second layer 7 according to Fig. 10): air-permeable, textile fabric in the form of a woven fabric, basis weight approx. 140 g / m² (determined according to DIN EN 12127 after 24 hours of air conditioning at a temperature of 20 °C and a relative humidity of 65%), oleophobic and hydrophobic finish by impregnation or coating using a fluorinated polymer.

[0324] Testing on multi-layered protective material

[0325] As a reference, the barrier effect against mustard gas is first determined on an unprocessed sample (10 cm x 10 cm) of this multi-layered protective material according to method 2.2 of CRDEC-SP-84010: < 0.08 pg / cm² 2 per 24 hours. Tests on the inventive protective clothing

[0326] In a manner known per se, protective clothing according to the invention with a protective function against chemical and / or biological and / or radioactive harmful and / or toxic substances (warning agents) ("ABC or CBRN protective function") in the form of trousers is produced from a multitude of textile pieces of the previously described multilayer protective material, as previously described in detail and illustrated, for example, in Figs. 1 to 6, wherein the individual textile pieces of the previously described multilayer protective material are each joined together by sewing.

[0327] As previously described in the general section, 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, wherein the protective clothing in the form of trousers, each completely arranged on or within the extremity section, has an extension section that can be opened or closed with at least one fastening means (here: zipper) for optionally widening or increasing the inner and / or outer diameter of the protective clothing in the form of trousers in the area of ​​the extension section, wherein the fastening means is connected only or exclusively to the second layer (i.e., to the outer material), namely sewn on, or wherein the fastening means is unconnected to the first layer (i.e.,the adsorption filter material).

[0328] The barrier effect against mustard gas at the so-called widening section (reference numeral no. 9 according to Figs. 1 to 6) is determined according to method 2.2 of CRDEC-SP-84010, both in the closed state of the widening section (see Fig. 2) with < 0.08 pg / cm² 2 per 24 h as well as in the open state of the widening section (see Fig. 3) also with < 0.08 pg / cm 2per 24 hours. This demonstrates that, due to the inventive design of the widening section and the combined use of the previously described multi-layered protective material, the protective function against chemical and / or biological and / or radioactive hazardous and / or toxic substances (warning agents) ("ABC or CBRN protection function") remains fully intact, while offering improved wearing comfort, particularly improved ease of donning and / or fitting and / or adaptability (i.e., adaptability to a user or wearer, or during wear), of the protective garment according to the invention compared to a protective garment without such a widening section. In this way, the protective trousers according to the invention can easily and conveniently be put on quickly and comfortably over existing clothing, including footwear, etc. (as over-trousers, so to speak), without impairing the protective performance.

[0329] Further tests are carried out on the opening section 27 in the form of a trouser fly (see Fig. 15), which is designed to be closed or opened with a further closure means in the form of a zipper (reference numeral no. 30 according to Fig. 18) with two closure elements or side parts (reference numerals no. 29 and 31 according to Figs. 15 and 16).

[0330] The following tests are carried out with this opening section 27 in the closed state.

[0331] As a reference, a protective garment in the form of trousers, as described above, serves as the initial reference. The closure of opening section 27 is a conventional, i.e., water- and air-permeable, zipper, which is also exposed, i.e., without any top or bottom covering. Here, the barrier effect against mustard gas is determined according to method 2.2 of CRDEC-SP-84010 with > 10 pg / cm³. 2measured per 24 hours (i.e., outside the applicant's specification). However, if, in accordance with the invention, this zipper is additionally covered on the top and bottom sides with a cover section (reference numerals 34 and 35 according to Figures 15 and 16) made of the previously described multilayer protective material, or alternatively, only with the adsorption filter material (= first layer) of the previously described multilayer protective material, the barrier effect against mustard gas, according to method 2.2 of CRDEC-SP-84010, is reduced to a value of 2.8 pg / cm². 2 per 24 h or 2.9 pg / cm² 2 improved every 24 hours (i.e., within the applicant's requirements or specifications).

[0332] In contrast, on another test specimen of the previously described protective clothing in the form of trousers, also according to the invention, a liquid-repellent, i.e., water-repellent, in particular waterproof, and windproof or airtight zipper (polyurethane (PU) zipper with additional PU side sections of the zipper) is used as the closure means of the opening section 27, resulting in a barrier effect against mustard gas of 1.8 pg / cm³ according to method 2.2 of CRDEC-SP-84010. 2per 24 h. If, in addition, this zipper is also covered or covered on the top and bottom with a cover section (reference numbers 34 and 35 according to Figs. 15 and 16) made of the previously described multilayer protective material or alternatively only of the adsorption filter material (= first layer) of the previously described multilayer protective material, the barrier effect against mustard gas according to method 2.2 of CRDEC-SP-84010 is reduced to values ​​< 0.08 pg / cm². 2 increased per 24 hours.

[0333] In this way, protective clothing is obtained which, overall, meets the applicant's requirements or specifications regarding the barrier effect against harmful and toxic substances.

[0334] Overall, the present invention provides, in light of the above considerations, high-performance protective clothing which offers improved wearing comfort, in particular improved putting on and / or donning and / or adaptability (i.e., adaptability to a user or wearer or in the wearing state), while at the same time providing excellent protection against harmful and toxic substances and also achieving excellent application properties, for example with regard to providing high air permeability with an overall low basis weight.
