Description
HOOD FOR PROTECTIVE GARMENT
The present invention relates to a hood, in particular for clothing items for protective and/or military purposes, such as nuclear-biologi-cal-chemical (NBC) protective suits/garments or the like. The present invention further relates to clothing items, in particular for protective and/or military purposes, such as NBC protective suits or the like, which are equipped with such a hood.
The present invention further relates to clothing items, in particular for protective and/or military purposes, such as NBC protective suits or the like. Finally, the present invention also relates to the use of an elastic hem for closing out the transition between a portion of a clothing item, in particular a hood, on the one hand and a further clothing item or outfit article (equipment article), in particular a respirator.
Persons who come into contact with poisonous materials which are absorbable via the respiratory tract pathways have to protect themselves against these poisonous materials by wearing a respirator. If, in addi-tion, there is a danger that the poisonous substances can also be taken up or absorbed via the skin or if it is part of their outfit (i.e. equip-ment), these persons (examples are armed forces personnel, firefighters, police personnel, members of special forces such as GSG 9, etc.) must additionally wear protective clothing, in particular NBC protective suits which prevent any contact of the poisonous materials with the skin or body and are generally equipped with a hood. The hood of such NBC
protective suits can have a circumferential (i.e. orbital or peripheral), in particular elastic, hem to form a face opening which is provided to receive a respirator, the hem of the hood being intended to abut the respirator in the use state.
However, this often leads to problems, since the transition between the hood/hem on the one hand and the respirator on the other is in most cases not adequately sealed. Consequently, poisonous or perilous materials can pass through the inadequately sealed transition between hood/hem on the one hand and respirator on the other and consequently the wearer of such a protective suit will come into contact with these materials, or these materials can even pass underneath the rim of the respirator, so that they are finally inhaled. This is particularly perilous for the wearer of such a protective suit when he or she is exposed to skin contact poisons, an example being mustard gas (bis(2 chloroethyl) sulfide, also known as Hd).
The present invention, then, has for its object to provide such a clothing item, preferably for protective and/or military purposes, such as an NBC protective suit or the like, or to be more precise a hood for such a clothing item as at least substantially avoids the problems described above. In particular, the present invention has for its object in relation to such a clothing item and/or in relation to such a hood to engineer the transition between clothing item/hood on the one hand and respirator on the other such that this transition is at least substantially sealed.
According to a first aspect of the present invention there is accordingly provided a hood, in particular for a clothing item, preferably for protec-tive and/or military purposes, such as an NBC protective suit or the like, the hood comprising a circumferential (i.e. peripheral/orbital) elastic hem to form a face opening, the face opening being provided to receive a respirator and the hem abutting the respirator in the use state, wherein the side of the hem that faces into the face opening (i.e., the side of the hem's face opening which faces toward the respirator in the use state) is provided with at least one circumferential (i.e. periph-eral/orbital) sealing element for closeout abutment of the respirator.
One fundamental idea of the present invention is thus to equip the above-described hood's hem which forms the face opening with at least one circumferential (i.e. peripheral/orbital) sealing element on that side of the hem which faces into the face opening, (i.e., on that side of the hem which faces toward the respirator in the use state). The result is that, in the use state, i.e., when the respirator is being worn, sealing of the transition between hood/hem on the one hand and respirator on the other is achieved or significantly improved.
In the use state, i.e., when the respirator is being worn, the sealing element rests on the respirator, creating a leakproof friction-grip con-nection with the underlying respirator.
The term "circumferential" (i.e. "peripheral"/"orbital" as synonyms) as used herein in relation to the hem and the sealing element is to be understood for the purposes of the present invention not only in its narrow sense but also in a wider sense. Therefore, "circumferential"
(i.e. "peripheral"/"orbital") can designate not only a state where the hem or the sealing element form a closed ring or circle, but also a state where the hem and the sealing element has two loose ends (for example when the hood comprises a closure or a closable opening), in which case the two loose ends of the hem and of the sealing element then can be placed on top of one another or be at least essentially brought to-gether at the ends. This too shall for the purposes of the present inven-tion also be understood as subsumed by the term "circumferential" (i.e.
"peripheral"/"orbital"). What is decisive is that the circumferential sealing element is at least essentially continuous, i.e., without channels and openings, so that it can abut sealingly against the respirator.
It is particularly advantageous when the sealing element abuts the respirator at least essentially linearly, and/or the sealing element pro-jects and/or protrudes from the hem. The at least essentially linear abutment of the respirator in the use state creates a higher contact pressure and consequently an improved closeout. To achieve an at least essentially linear abutment of the respirator by the sealing element, the sealing element must be appropriately configured.
Further advantages, properties, aspects and features of the present invention will be apparent from the following description of a preferred operative example depicted in the drawing, where Fig. 1 shows a schematic depiction of an inventive clothing item equipped with an inventive hood;
Fig. 2 shows a schematic depiction of an inventive hood in the use state;
Fig. 3A shows an enlarged depiction of that region of the inventive hood in the use state which is marked in Fig. 2 by broken lines;
Fig. 3B shows an enlarged depiction of the region marked in Fig.
3B by broken lines or of the cutout marked accordingly in Fig. 3A;
Fig. 4A shows a schematic plan view of the hem equipped accord-ing to the present invention with sealing elements;
Figs. 4B, C show a schematic cross section through a hem according to two embodiments which is equipped according to the pres-ent invention with sealing elements;
Fig. 5 shows a side view of the inventive hood in the use state;
and Fig. 6 shows an enlarged cross-sectional depiction along the line VI depicted in Fig. 5.
Fig. 1 shows an inventive clothing item 2, preferably for protective and/or military purposes, such as an NBC protective suit or the like, that is equipped with an inventive hood 1. Said hood 1 has a circumfer-ential elastic hem 3 to form a face opening 4. As evident from Fig. 2 and Fig. 3A, the face opening 4 is provided to receive a respirator 5.
The hem 3 abuts the respirator 5 in the use state.
Fig. 3B shows the region specially marked in Fig. 3A, as a schematic enlargement, the hem 3 which abuts the respirator 5 being flipped upward in the arrow direction in the depiction of Fig. 3B, revealing the sealing element 6 which, according to the present invention, is provided for closeout abutment of the respirator 5 and which is provided on that side of the hem which faces into the face opening 4 or on that side of the hem which faces the respirator 5 in the use state.
In a particular embodiment, the sealing element 6 provided according to the present invention abuts the respirator 5 at least essentially linearly.
It is appropriately configured for this purpose, as Fig. 3B shows. The advantages of the at least essentially linear abutment were described above in the general descriptive part.
The functioning of the sealing element 6 which is provided according to the present invention is illustrated in Fig. 6 in conjunction with Fig. 5.
Fig. 6 is an enlarged cross-sectional depiction along the broken line VI
depicted in Fig. 5. As can be seen from Fig. 6, in the use state, i.e., when a respirator 5 is being worn, the sealing elements 6 abut the respirator 5 at least essentially linearly together with the hem 3, the hem 3 pressing the sealing elements 6 against the respirator 5. The at least essentially linear abutment of the sealing elements 6 significantly increases the contact pressure and ensures excellent close-out.
As evident from Fig. 4A, it can be advantageous to provide a plurality of sealing elements 6 on the hem 3, preferably at least two sealing elements 6. Various configurations with regard to the arrangement of the sealing elements are possible in such a case. As Fig. 4A shows, the individual sealing elements 6 may be in an at least essentially parallel arrangement. In addition, it is also possible, for example, to arrange the individual sealing elements in such a way that they form a honey-comblike construction (not depicted). What is decisive is solely that a leakproof connection between hem 3 and respirator 5 is achieved in the use state.
As cross-sectional depictions 4B and 4C show, the sealing element 6 may project and/or protrude from the hem 3. This, instead of a two-dimensional abutment, provides an essentially linear abutment in the use state, which is associated with a higher contact pressure and with a higher closeout.
The sealing element 6 provided according to the present invention is in particular configured as a sealing ring, as a sealing lip or as a sealing protrusion. In general, this creates an elevation or uprising on the hem 3.
The sealing element 6 may be secured to the hem 3, in particular durably joined to the hem 3, preferably by stitching, interweaving, adhering, stapling, welding or the like; such an embodiment is depicted in Fig. 4B. In another embodiment, the sealing element 6 may however also be part of the hem 3, in particular the sealing element 6 and the hem 3 may be configured as a one piece structure; such an embodiment is depicted in Fig. 4C.
The sealing element provided according to the present invention may be thread, ligament, string or strip shaped or else webbed or else honey-comb shaped.
In general, the sealing element 6 consists of an elastically deformable material. Care should be taken in particular to ensure that the elasticity of the sealing element 6 corresponds at least essentially to the elasticity of the hem 3 or even exceeds it.
In a particular embodiment of the present invention the sealing element 6 has a relative elastic extensibility or extension, based on its original length, of not less than 20%, in particular not less than 30%, preferably not less than 50 %, more preferably not less than 70 % and even more preferably not less than 85 % or more. In a particular embodiment of the present invention the 25 C modulus of elasticity in stretching of the material of which the sealing element 6 consists is not more than 108 N=m 2, in particular not more than 107 N=m 2, preferably not more than 5= 106 N=m 2, and is preferably in the range from 5= 105 N=m 2 to 9= 106 N=m 2.
In a further embodiment of the present invention it may be advanta-geous when the Fig. 4B cross-sectional thickness d of the sealing element 6 is not less than 1/4, in particular not less than 1/3, preferably not less than 2/3 and more preferably not less than 3/4 of the Fig. 4B
cross-sectional thickness D of the hem 3. In particular, the sealing element 6 should project and/or protrude from the hem 3 by not less than 0.1 mm, in particular not less than 0.25 mm, preferably not less than 0.4 mm, more preferably not less than 0.6 mm and even more preferably to an extent of 1 mm or more. A particularly good sealing effect can be achieved as a result.
The material of which the sealing element 6 which is provided accord-ing to the present invention consists may be for example any kind of gum, latex, elastic plastic, etc., as long as it is suitable for use in the realm of the present invention. In particular, these materials should advantageously have a certain thermal and UV stability and also, what is more, a certain resistance to aggressive media, in particular warfare agents, but also to body fluids, in particular sweat. It is also of advan-tage for the material to be water repellent.
Examples of materials suitable according to the present invention are for example certain kinds of so called elastofibers (see ROMPP-Chemie-lexikon, 10th edition, volume 2, 1997, pages 1104 to 1106, headword "Elastofasern", Georg Thieme Verlag Stuttgart/New York); elastofibers are manufactured fibers which are extremely extensible and, after the tensile force has been removed, substantially return into the original state. The most important representatives are elastane, fibers composed of high polymers which consist to at least 85 % by weight of segmented polyurethane, and elastodiene, fibers which consist of synthetic poly-isoprene or of high polymers formed by polymerization of one or more dienes with or without one or more vinyl monomers. The second group may also be considered as including the elastomeric fibers formed from natural rubber. Elastodienes are frequently vulcanized. Elastic proper-ties are also possessed by a bicomponent fiber consisting of polyamide and polyurethane. See the aforementioned literature reference for further details. The dimensions of such fibers must be appropriately adapted for the purposes of the present invention. Such fibers can be incorporated with the hem material for example.
The present invention relates to a hood, in particular for clothing items for protective and/or military purposes, such as nuclear-biologi-cal-chemical (NBC) protective suits/garments or the like. The present invention further relates to clothing items, in particular for protective and/or military purposes, such as NBC protective suits or the like, which are equipped with such a hood.

cross-sectional thickness D of the hem 3. In particular, the sealing element 6 should project and/or protrude from the hem 3 by not less than 0.1 mm, in particular not less than 0.25 mm, preferably not less than 0.4 mm, more preferably not less than 0.6 mm and even more preferably to an extent of 1 mm or more.

The dimensions of such fibers must be appropriately adapted for the purposes of the present invention. Such fibers can be incorporated with the hem material for example.
As depicted in Fig. 1 and Fig. 2 for example, the present invention's hood 1 including the face opening 4 may comprise, in particular on the side portion of the face opening 4, a fastener 7, for example in the form of a touch and close fastener or zip fastener. A fastener makes it easier to put on the respirator and also enhances the wear comfort, since the hood can be opened in situations where the respirator is not needed.
But it should be ensured that the hood fastener 7 is at least essentially tightly closable. In principle, the fastener 7 can be disposed at any desired location of the face opening 4, for example laterally but also centrally with regard to the face opening 4; in practice, however, it will be found advantageous in particular for reasons of practicability, wear comfort and superior sealability for the fastener 7 to be situated on the side portion of the face opening 4.
The hood 1 may be made detachable from the rest of clothing item 2, for example via a touch and close fastener or a zip fastener; with this embodiment too care must be taken to ensure that the rest of clothing item 2 and the hood 1 are at least essentially tightly conjoinable with one another. It is similarly possible for the hood 1 to be part of cloth-ing item 2, in particular to be stitched thereto or even form a one piece construction therewith.
In a further embodiment it may be provided, as depicted in Fig. 1 and Fig. 2 for example, that the present invention's hood 1 comprises at least one loop, tab or the like 8 above the face opening 4. This makes it possible in particular to adjust the face opening 4 and/or the hood 1, in particular when the hood 1 is being worn in conjunction with a helmet or some other head covering on top of the hood 1.
But it should be ensured that the hood fastener 7 is at least essentially tightly closable.

This makes it possible in particular to adjust the face opening 4 and/or the hood 1, in particular when the hood 1 is being worn in conjunction with a helmet or some other head covering on top of the hood 1.
To enable poisonous materials, in particular warfare agents, to strike through the hood 1 and/or, alternatively, to ensure removal of any poisonous materials which have succeeded in penetrating into the hood 1, it may be provided that the hood 1 is fully or partially lined on its inside surface with an inside material which comprises an adsorption-capable material, in particular activated carbon, for example in the form of activated carbon granules or spherules or activated carbon fibers.
Alternatively or in combination with such an adsorption-capable mate-rial it may be provided that the inside material comprises a water vapor pervious, at least essentially gas and/or air impervious barrier layer which prevents or at least retards the passage of harmful gases or liquids, in particular chemical warfare agents. Such inside materials, which are endowed with an absorptive layer and/or a barrier layer, are known as such from the prior art. Reference may be made in this regard for example to DE 198 29 975 Al, DE 39 39 373 Al, DE 38 15 720 Al, DE 195 19 869 Al, DE 198 42 274 Al and DE 102 40 548, whose respective disclosure contents are hereby incorporated herein by reference.
In a particular embodiment the entire clothing item 2 may be wholly or partly equipped with such an inside material.
The present invention accordingly further provides a clothing item, in particular for protective and/or military purposes, such as an NBC
protective suit or the like. The above observations relating to the hood of the present invention and to the clothing item of the present invention respectively apply accordingly.
The present invention accordingly also provides a clothing item, in particular for protective and/or military purposes, such as an NBC
