Description

The present invention relates to a hood, in particular for clothing for protective or military purposes, such as NBC protective suits or the like, according to the preamble of claim 1. Furthermore, the present invention relates to clothing, in particular for protection or military purposes, such as ABC Protective suits or the like, which are equipped with such a hood.

Furthermore, the present invention relates to garments, in particular for protective or military purposes, such as ABC protective suits or the like, according to the preamble of claim 17. Finally, the present invention also relates to the use of an elastic seam for sealing the transition between a part of a Garment, in particular a hood, on the one hand and another item of clothing or equipment, in particular a respirator, on the other hand according to the preamble of claim 19.

Persons in contact with toxic substances that can be absorbed through the respiratory tract must protect themselves against these toxins by wearing a respirator. Moreover, if there is a risk that the toxic substances may also be absorbed or absorbed through the skin, or if this is technically necessary, these persons (eg soldiers, firefighters, police officers, members of special units such as GSG 9 etc.) in addition wear protective clothing, in particular NBC protective suits, which avoid contact of the toxins with the skin or the body and are usually equipped with a hood. The hood of such ABC protective suits may comprise a circumferential, in particular elastic, seam for forming a visual field opening intended to receive the respiratory mask, the hem of the hood being intended to be applied to the respirator in use (see, for example, GB 2 078 491).

However, this often leads to problems, as the transition from hood or hem on the one hand and respirator on the other hand, in most cases is not sufficiently sealed. This can consequently lead to toxic or dangerous substances can pass through the insufficiently sealed transition between the hood or hem on the one hand and respirator on the other hand, and consequently the wearer of such a protective suit comes into contact with these substances or even these substances under the edge of the Respirator can get so that they are finally inhaled. This is particularly dangerous for the wearer of such a protective suit when exposed to so-called skin poisons, such as. B. Mustard gas (bis (2-chloroethyl) sulfide, also called Lost).

An object of the present invention is now to provide a garment, preferably for protective or military purposes, such as ABC protective suit or the like, or a hood for such a garment, which at least largely avoids the problems described above. In particular, an object of the present invention is to design the transition between garment or hood on the one hand and respirator on the other hand in such a garment or in such a hood on the other hand, that this transition is at least largely sealed.

The above-described object is, as proposed, achieved by a hood according to claim 1 or a garment according to claim 17. Further, advantageous developments and refinements are the subject of the dependent claims.

The present invention according to a first aspect is thus a hood, in particular for a garment, preferably for protective or military purposes, such as ABC protective suit or the like, wherein the hood has a circumferential elastic seam to form a visual field opening, wherein the visual field opening is provided for receiving a respirator mask and wherein the hem in the state of use rests against the respirator mask, wherein on the side facing in the field of view opening of the hem (ie on the side facing the respirator in use state side of the field opening of the seam) at least one circumferential sealing element for sealing Concerning the respiratory mask is provided.

A basic idea of the present invention therefore consists in equipping the seam of the previously described hood forming the visual field opening on the side of the hem pointing in the visual field opening (that is to say the side of the seam pointing towards the respiratory mask in use) with at least one circumferential sealing element. This means that in use, so when wearing the respirator, a seal the transition between the hood or hem on the one hand and respirator on the other hand is achieved or the sealing of this transition is significantly improved.

In use, d. H. when wearing the respirator, the sealing element rests on the respirator, and it creates a tight and frictional connection with the underlying respirator.

The term "circumferential", as it is understood according to the invention with respect to the seam and the sealing element, is understood in the context of the present invention both in its narrower sense as well as in a further meaning. Thus, the term "circumferential" may refer to both a state where the seam or sealing element forms a closed ring or circle, but also a state where the seam and the sealing element have two loose ends (eg, when the hood has a closure or a closable opening), wherein the two loose ends of the seam and the sealing element can then be superimposed or at least substantially brought together at the ends. Again, this is understood by the term "circumferential" according to the invention. It is crucial that the circumferential sealing element is at least substantially continuous, d. H. without channels and openings, so that it can rest sealingly on the respirator.

It is particularly advantageous if the sealing element is formed at least substantially linearly adjacent to the respirator mask and / or the sealing element is formed projecting or projecting from the hem. By the at least substantially linear concerns to the respirator in use, a higher contact pressure is achieved, and thus an improved seal. To achieve at least substantially line-shaped concern of the sealing element to the respirator, the sealing element is to be formed accordingly.

Fig. 1 shows an inventive garment 2, preferably for protective and / or military purposes, such as an ABC protective suit or the like, which is equipped with a hood 1 according to the invention. The hood 1 has a circumferential elastic seam 3 for forming a visual field opening 4. As can be seen from FIG. 2 and FIG. 3A, the visual field opening 4 is provided for receiving a respiratory mask 5. In this case, the hem 3 applies in the use state of the respirator 5.

FIG. 3B shows the area marked separately in FIG. 3A as a schematic enlargement, the hem 3 resting against the respiratory mask 5 being flipped upward in the direction of the arrow in FIG. 3B, so that according to the invention for sealing engagement with the respiratory mask 5 provided sealing element 6, which is provided on the facing in the face opening 4 side of the hem or on the in use state to the respirator 5 facing side of the hem comes to light.

According to a particular embodiment, the sealing element 6 provided according to the invention is applied to the respiratory mask 5 at least substantially in a line. For this purpose, as shown in FIG. 3B, it is designed accordingly. The advantages of the at least substantially line-shaped concern have been previously described in the general description part.

The mode of operation of the sealing element 6 provided according to the invention is illustrated in FIG. 6 in conjunction with FIG. 5. FIG. 6 is an enlarged cross-sectional view along the dashed line VI shown in FIG. As shown in Fig. 6, are in use, d. H. when wearing a respirator 5, the sealing elements 6 at least substantially linearly on the respirator 5 together with the seam 3, wherein the seam 3 presses the sealing elements 6 to the respirator 5. Due to the at least substantially linear concerns of the sealing elements 6, the contact pressure is significantly increased and achieved an excellent seal.

As can be seen from FIG. 4A, it may be advantageous to provide a plurality of sealing elements 6 on the seam 3, preferably at least two sealing elements 6. Different configurations with respect to the arrangement of the sealing elements are possible. As FIG. 4A shows, the individual sealing elements 6 can be arranged at least substantially parallel to one another. In addition, for example, there is the possibility of the individual To arrange sealing elements so that they form a honeycomb-like structure (not shown). Decisive alone is that in use a tight connection between seam 3 and 5 respirator mask is achieved.

As the cross-sectional representation 4B and 4C show, the sealing element 6 may be formed protruding from the seam 3. As a result, instead of a flat support or instead of a flat abutment, a substantially linear abutment is achieved in the use state, which is associated with a higher contact pressure and with a higher seal.

In particular, the sealing element 6 provided according to the invention is designed as a sealing ring, sealing lip or sealing projection. In general, an elevation or increase on the seam 3 is created in this way.

The sealing element 6 may be attached to the seam 3, in particular be permanently connected to the seam 3, preferably by sewing, weaving, gluing, stapling, welding or the like; such an embodiment is shown in Fig. 4B. According to another embodiment, the sealing element 6 but also be part of the seam 3, in particular, the sealing element 6 and the seam 3 may be integrally formed; such an embodiment is shown in Fig. 4C.

As far as the sealing element provided according to the invention is concerned, it may be thread-shaped, band-shaped, cord-shaped or strip-shaped or web-like or else honeycomb-shaped.

In general, the sealing element 6 consists of an elastically deformable material. Care should be taken in particular that the elasticity of the sealing element 6 corresponds at least substantially to the elasticity of the seam 3 or even exceeds it.

According to a particular embodiment of the present invention, the sealing element 6 has a relative elastic extensibility or elongation, based on its initial length, of at least 20%, in particular at least 30%, preferably at least 50%, preferably at least 70%, particularly preferably at least 85% or more. According to a particular embodiment of the present invention, the modulus of elasticity of elasticity of the material constituting the sealing element 6 at 25 ° C is at most 10 ⁸ N · m ^-2 , in particular at most 10 ⁷ N · m ^-2 , preferably at most 5 · 10 ⁶ N · M ^-2 , and is preferably in the range of 5 · 10 ⁵ N · m ^-2 to 9 · 10 ⁶ N · m ^-2 .

According to a further embodiment of the present invention, it may be advantageous if the cross-sectional thickness d of the sealing element 6 shown in FIG. 4B is at least 1/4, in particular at least 1/3, preferably at least 2/3, particularly preferably at least 3/4, that in 4B corresponds to the illustrated cross-sectional thickness D of the seam 3. In particular, the sealing element 6 should protrude to at least 0.1 mm, in particular to at least 0.25 mm, preferably to at least 0.4 mm, preferably to at least 0.6 mm, particularly preferably to 1 mm and more, from the seam (3) or be formed protruding. As a result, a particularly good sealing effect can be achieved.

As regards the material of which the sealing element 6 provided according to the invention is made, for example, all types of rubbers, latices, elastic plastics, etc. may be considered, provided that they are suitable for use in the context of the present invention. In particular, these materials should advantageously have a certain heat and UV resistance and, moreover, also have a certain resistance to aggressive media, in particular warfare agents, but also to body fluids, in particular sweat. Moreover, it is advantageous if the material is water-repellent.

Examples of suitable materials according to the invention are for. B. certain types of so-called elastofibres (see RÖMPP Chemielexikon, 10th Edition, Volume 2, 1997, pages 1104 to 1106, keyword "elastofibers", Georg Thieme Verlag Stuttgart / New York); These are man-made fibers that are extremely elastic and largely return to their original state after the tensile force has been removed. The most important representatives are elastane, fibers of high polymers which are at least 85 wt .-% of segmented Polyurethane, and elastomers, fibers consisting of synthetic polyisoprene or high polymers, which are formed by polymerization of one or more dienes, optionally with the addition of one or more vinyl monomers. For the second group you can also count the rubber fibers made of natural rubber. Elastodiene is often vulcanized. Elastic properties are also possessed by a bicomponent fiber made of polyamide and polyurethane. For further details, reference may be made to the aforementioned reference. The dimensions of such fibers are to be adapted accordingly for the purposes of the invention. Such fibers can be sewn to the hem material, for example.

As shown, for example, in Figures 1 and 2, the hood 1 according to the invention, including the visual field opening 4, in particular at the lateral part of the visual field opening 4, can have a closure 7 (eg in the form of a hook-and-loop fastener or a zipper). As a result, on the one hand the placement of the mask is facilitated; On the other hand, this increases the comfort, since in situations where the respirator is not needed, the hood can be opened. However, it should be ensured that the hood closure 7 can be closed at least substantially tight. In principle, the closure 7 can be arranged at any point of the visual field opening 4 (eg laterally or also centrally with respect to the visual field opening 4); in practice, however, it has proved to be particularly practical for reasons of practicality, wearing comfort and better sealability when the closure 7 is attached to the lateral part of the visual field opening 4.

As far as the hood 1 is concerned, it may be removable from the rest of the garment 2 (eg via a hook-and-loop fastener or zipper); Care must also be taken in this embodiment that the remaining garment 2 and the hood 1 are at least substantially connectable to each other. Similarly, it is possible that the hood 1 is part of the garment 2, in particular hereby sewn or even integrally formed therewith.

According to a further embodiment, it may be provided, as shown for example in FIGS. 1 and 2, that the hood according to the invention 1 above the visual field opening 4 at least one loop, tab or the like 8 has. In particular, this makes it possible to adjust the visual field opening 4 or the hood 1, in particular if the hood 1 is worn in conjunction with a helmet or another headgear that is still seated on the hood 1.

In order to allow a penetration of toxic substances, in particular warfare agents, through the hood 1 and / or also to ensure removal of any penetrated into the hood 1 toxic substances, it may be provided that the hood 1 on its inside completely or partially is lined with an inner material which comprises an adsorptive material, in particular activated carbon (for example in the form of activated carbon particles or activated carbon fibers). Alternatively, or in combination with such an adsorptive material, it may be provided that the inner material comprises a water vapor permeable, at least substantially gas or air impermeable barrier layer, which prevents or at least delays the passage of harmful gases or liquids, in particular chemical warfare agents. Such inner materials, which are configured with an adsorption layer and / or a barrier layer, are known as such from the prior art. In this regard, reference may be made, for example, to DE 198 29 975 A1, DE 39 39 373 A1, DE 38 15 720 A1, DE 195 19 869 A1, DE 198 42 274 A1 and DE 102 40 548, their respective disclosure is hereby incorporated by reference.

According to a particular embodiment, all or part of the garment 2 may be provided with such inner material.

Another object of the present invention according to another aspect of the present invention is a garment, in particular for protective or military purposes, such as an ABC protective suit or the like, according to the preamble of claim 17. Here, the above statements apply to the invention Hood or to the garment according to the invention accordingly.

The subject of the present invention is therefore also a garment, in particular for protective or military purposes, such as an ABC protective suit or the like, the garment having at least one opening for a body part (eg hand, arm, foot, leg or head ) with a circumferential elastic seam for forming this opening, wherein the opening for receiving a further item of clothing in particular with a smooth surface structure (eg protective glove etc.) and / or for receiving a piece of equipment (eg respiratory mask, etc.) is provided and in the state of use the hem is in contact with the further item of clothing and / or the piece of equipment, at least one circumferential one on the side of the seam facing the further item of clothing and / or the item of equipment, preferably on the side of the seam pointing in the opening Sealing element for sealing concern to the other Bekleidu or piece of equipment is provided. For further details, reference may be made to the above statements with respect to the hood according to the invention or the item of clothing according to the invention, which apply accordingly here.

Thus, another basic idea of the present invention is to seal the transition between the openings provided on garments for body parts on the one hand and other garments or equipment on the other hand by providing the corresponding opening with a seam which has at least one sealing element on the corresponding side having previously described type.

Finally, another object of the present invention is the use of an elastic seam for sealing the transition between a part of a garment, in particular a hood, on the one hand and another garment and / or a piece of equipment, in particular a respirator, on the other hand, wherein on the other Garment or the equipment counterpart facing side of the seam at least one circumferential sealing element is provided for sealing concern to the further garment or to the equipment item. The statements relating to the inventive Hood or garment according to the invention apply correspondingly with respect to the use according to the invention.

Further embodiments, modifications and variations of the present invention will be readily apparent to those skilled in the art upon reading the description and practicable without departing from the scope of the present invention.
