Definitions
- the invention relates to a flame protection hood with at least one outer support layer and at least one inner support layer, a filter layer for filtering pollutants from the air being arranged between the outer support layer and the inner support layer, the filter layer having at least two interconnected filter cut parts , which are sewn together at least partially via at least one filter seam and that the connection of the filter cut parts is at least partially sealed.
- Flame protection hoods have the main task of protecting the wearer - mostly firefighters and firefighters - from the effects of heat and fire. They are used particularly in fire brigade operations where respiratory protection is worn.
- the outer and inner backing layers are usually made up of a soft and stretchable fiber or textile product such as a woven or knitted fabric, such as, for example, fire-resistant textile fibers (eg: Kevlar or aramide) or other fabrics, and at least partially assume the task thermal insulation.
- a soft and stretchable fiber or textile product such as a woven or knitted fabric, such as, for example, fire-resistant textile fibers (eg: Kevlar or aramide) or other fabrics, and at least partially assume the task thermal insulation.
- flame protection hoods which have filter layers. These prevent the penetration of the substances and contamination with the skin of the wearer, which usually has fine particles in sizes in the mm and pm range. These filter layers are usually less elastic than the carrier layers.
- a disadvantage of such flame protection hoods is that they cannot be cut tightly due to the poor elasticity of the filter layer and therefore sit poorly on the support.
- the neck area in particular, there are large voids between the neck of the wearer and the neck area.
- the shortest possible preparation time is a high priority.
- the layers can move against each other when the hood is tightened, thus reducing the protective effect and requiring lengthy ordering and sorting of the layers.
- the filter layer is therefore often sewn or quilted with at least one carrier layer so that a stable connection between the carrier layer and the filter layer is possible.
- this requires openings in the filter layer, in particular when the seams are stretched, through which otherwise filtered particles can pass the filter layer.
- EP 1 308 186 A2 describes a protective suit with a protective hood, which has sewings between a filter layer and the carrier layers. So that a person can put on the protective suit, it is very wide and has a hip belt to compensate for the too wide shape.
- WO 2018129195 A1 discloses a protective hood with a filter layer, the filter layer having a plurality of parts which are sealingly connected to one another. This can prevent particles from reaching the carrier of the protective hood via the seams of the parts of the filter layer, and it can be achieved that a complex three-dimensional structure of the filter layer can be shaped better. In this way, a shape that matches the head and neck area of the wearer can be achieved.
- the filter layer is not very elastic and therefore the neck area of the protective hood has to be made very large, which leads to a less suitable cut.
- the object of the invention is therefore to provide a flame protection hood which enables the shortest possible preparation time with good protection of the wearer, but at the same time is adapted as well as possible to the body shape of the wearer.
- this object is achieved in that the outer carrier layer has a smaller cut than the filter layer, at least in the collar area, in the unloaded state.
- the shape of the less elastic membrane can be better adapted to the complex three-dimensional shape of the flame protection hood.
- the resulting perforations or openings in the membrane result in the risk of penetration of harmful substances and particles.
- this can be prevented by the seal, as a result of which the filter layer remains intact and its filter function is not reduced.
- the entire connection of the filter cut parts is preferably sealed.
- Sealing means that no substances can pass through the connection that cannot pass through a continuous part of the membrane.
- the seal can also hinder the passage of substances that can otherwise pass through continuous parts of the membrane. It is also advantageous if the flame protection hood has a neck opening which is delimited from a collar area. No back or breast bib can be provided.
- a flame protection hood has a collar area which has a support surface on its inside for contacting a collar of a protective jacket. This allows the flame protection hood, which is put on after a jacket, to connect to the collar area above the collar of the jacket and finally protect the neck.
- the collar area is designed to be arranged outside a collar of a jacket of the wearer in a tightened state. This is particularly advantageous in the case of short embodiments without a back or breast bib.
- the collar area can close with the collar of the jacket and thus create a tight connection against pollutants such as suspended particles without the flame protection hood having to be put on before putting on or closing the jacket. This increases the comfort of the firefighters, who can only put on the flame protection hood at a later point in time.
- the filter layer can be made, for example, of microporous PTFE (polytetrafluoroethylene), polyester or PU (polyurethane).
- the filter layer has at least two filter cut parts, which are sewn together at least partially via at least one filter seam, then the shape of the filter layer can be optimally adapted to the head and upper body of the wearer.
- the manufacturing process is also made easier because flat filter cut parts can be cut and sewn together afterwards.
- connection of the filter cut parts is at least partially sealed. This prevents the undesired penetration of particles through the connection.
- the seal should be at least so tight that only particles or substances of that size or type can pass through that can also pass through continuous parts of the filter layer.
- the sealing can be carried out with the same material from which the filter layer essentially consists.
- an adhesive tape seals the connection of the filter cut parts, which is preferably welded to the filter cut parts.
- the adhesive side of the adhesive tape can be fixed to the filter cut parts and welded to them, for example by hot air welding or ultrasonic welding.
- the filter layer has at least two filter cut parts which are welded together. This is a safe connection that cannot be overcome by particles.
- an adhesive tape can seal the connection of the filter cut parts.
- the adhesive tape is preferably welded to the filter cut parts.
- the filter seam is at least partially sealed.
- the sealing of the seam prevents the risk that the backing layer is perforated through the seam, through which particles can pass undesirably.
- an adhesive tape is arranged on the filter seam of the filter layer, which is preferably welded to the filter layer. This allows the seam to be made first and then the sealing tape to be placed on it. As a result, larger holes that occur due to sewing can also be closed. If the adhesive tape is made of the same material as the filter layer parts, it can bond permanently and well to the filter layer parts.
- the flame protection hood preferably has a face opening and the face opening has a forehead region for exposing the forehead of the wearer in the tightened state. This is particularly useful if breathing masks such as 2-point masks are used, which would otherwise not fit snugly on the forehead and can therefore close.
- the face opening of the flame protection hood preferably extends to just above the mask in the applied position, so that as little facial skin as possible remains free.
- the filter layer has at least two filter cut parts connected to one another, which are sewn together at least partially via at least one filter seam and that the connection of the filter cut parts is at least partially sealed
- the filter layer is at least partially sewn at its edge sections to the outer carrier layer or the inner carrier layer or both carrier layers.
- the filter layer is connected sufficiently firmly to the other layers, making quilting or other area-wide sewings unnecessary.
- the filter ability is maintained over the surfaces of the filter layer without reducing comfort or making it difficult to put on.
- Edge sections mean the boundary areas of the filter layer, that is to say the edges and corners of the filter layer. Usually there are such ends or Cut edges in the area of openings through which, for example, the neck or face of the user is passed. If certain areas of the flame protection hood are designed without a filter layer, these are also limited by border areas.
- the edge regions are therefore generally strip-shaped regions which extend along an edge of the filter layer.
- At least one surface section is arranged between the edge sections, which is essentially free of sewings to the outer carrier layer or the inner carrier layer. It is particularly advantageous if this surface section extends in the neck area and / or in the areas around a face opening and / or the side areas of the flame protection hood. The surface section preferably extends over a large part of the surface of the filter layer.
- individual sewing sections can be provided between the surface sections, which preferably have sealed seams. This is not particularly problematic in areas that are not very exposed, for example in the area of the back of the head, which is usually covered by the helmet of the firefighter or the firefighter.
- the filter layer, apart from the edge sections, is essentially free of sewings to the outer carrier layer or the inner carrier layer. It is particularly advantageous if the filter layer is free of sewings to the carrier layers except for the edge sections.
- the flame protection hood has a first edge section around a neck opening of the flame protection hood and a second edge section around a face opening of the flame protection hood.
- the flame guard has a breast bib and a back bib, the breast bib being made longer than the back bib, this prevents the back bib from unfavorably folding when the jacket is put on after the flame hood is put on. At the same time, however, adequate protection of the neck is made possible.
- the back bib preferably extends only over the neck of the user in the tightened position and seals this area with a jacket.
- the filter layer has at least two filter cut parts which have a connection which is essentially impenetrable for particles. This can ensure that no particles can pass through the filter layer through the connection.
- the permeability of the filter layer water vapor can be reduced in these areas, but this is not a problem since the remaining areas of the filter layer provide adequate ventilation.
- the filter layer has at least one seam lug that is connected to at least one carrier layer.
- This enables a dense filter layer, but a stable connection between the layers. This prevents unwanted shifts between the layers.
- the filter layer no longer has to be connected to the carrier layers via seams penetrating the filter layer.
- the connection via the seam flag is more flexible and adapts more easily to deformations of the flame protection hood, for example when pulling it over the head, but nevertheless enables a stable connection without unwanted folds or wrinkles.
- the filter layer can nevertheless be connected to carrier layers via penetrating seams, this is not particularly problematic at end regions such as a face hole.
- At least the outer carrier layer is connected to the seam flag.
- the filter layer parts are sewn overlapping on the filter seam and at least one filter layer part at least partially forms the seam flag.
- the seam flag is automatically provided at least partially by sewing.
- the seam flag can also be formed by a further piece of fabric which is sewn together with the filter layer parts.
- the seam flag formed by the filter layer part can also be extended by additional pieces of fabric.
- the seam flag can also be formed by sewing a loop of the filter layer.
- the seam flag can be sewn onto at least one carrier seam flag of a carrier layer.
- the adhesive tape is arranged on the filter layer, it is not visible on the one hand and on the other hand it is protected against external influences and damage.
- an annular collar region of the flame protection hood has at least one elastic traction region which essentially extends along the circumference of the collar region.
- the arrangement of the pull area allows the circumference of the collar area to adapt to the neck thickness of the wearer as soon as the flame protection hood has been pulled over the wearer's head.
- the circumference of the collar area is preferably chosen so large that the head - which is generally larger in circumference than the neck - fits well through the collar area when the tension area is tensioned. As soon as the collar area sits on the neck, the pull area contracts. together so that the collar area fits comfortably to the neck circumference. This reduces or prevents air pockets between the neck and the collar area. This also reduces the risk of slipping when fully tightened.
- the pulling area is an area that brings the collar area into a contracted shape in a relaxed position, but allows elastic expansion of the collar area when tensioned.
- the outer carrier layer has a smaller cut than the filter layer, at least in the collar area in the unloaded state.
- the different cuts ensure that the filter layer in the collar region between the seams with which it is connected to the outer carrier layer is larger than the collar region of the outer carrier layer.
- the circumference of the filter layer in the collar area is therefore larger than the circumference of the outer carrier layer in the collar area. In the event of a relief, this means that the outer carrier layer contracts elastically to such an extent that it takes on a relieved state.
- the elastic tensile region has at least one elastic band which is connected at least to the outer carrier layer.
- the elastic traction area has at least one elastic band, which is connected at least to the inner carrier layer.
- the rubber train can be arranged so that it not only brings the filter layer, but also at least one carrier layer into a folded position in a relaxed position.
- the elastic band means an elastic band which has a certain length in the relaxed position and can be brought apart by pulling it into a tensioned position in which its length is greater.
- These flameproof hoods usually have a head area, a collar area and an upper body area, which are arranged on the head, neck or upper body of the wearer when worn as intended.
- a pulling area is arranged on each side surface and a pulling area on a neck surface, the pulling areas being arranged essentially at the same height. This ensures that the collar area folds evenly, which is comfortable.
- the height relates to the height along a main axis of the flame protection hood, along which the head region, the collar region and the upper body region are arranged.
- the maximum passage size of the filter layer for particles is less than 2 pm. This minimizes the health risk for the wearer, but still provides a breathable hood.
- the filter layer is designed to prevent the passage of health pollutants, preferably polycyclic aromatic hydrocarbons or the like. This means that these toxic substances can no longer get to the skin of the wearer of the flame protection hood.
- Health pollutants mean substances that are harmful to humans and have a negative impact on the human organism, especially those that are Regulation (Regulation (EC) No. 1907/2006) were classified as harmful to health.
- a back area of the flame protection hood which is arranged in the intended state in the area of the back of the head, is free of the filter layer.
- the area of the back of the head is arranged in the area of the wearer's parietal bone, that is to say in the cranial-dorsal area of the head, above the parietal lobe of the brain. Since this area is usually covered by the protective helmet during operations, the particle load there is limited to a minimum. Accordingly, the arrangement of the filter layer is not necessary, but this area is made more elastic by omitting the filter layer. This means that the flame protection hood sits better without significantly increasing the particle load on the support. At the same time, the relatively cost-intensive filter layer is saved, which leads to cheaper production.
- the protective clothing with at least one protective jacket and at least one flame protection hood, the protective jacket having a collar and the flame protection hood having a collar area and the collar area being arranged outside the collar in a properly designed state.
- the flame protection hood is a flame protection hood according to the invention.
- the collar of the jacket extends around the neck of the wearer or user when in use.
- Dressed or applied state means a state in which a user such as a firefighter or a firefighter is wearing a protective jacket and the flame protection hood as intended on his upper body or on his head.
- FIG. 1 shows a first embodiment of a flame protection hood according to the invention in a front view
- FIG. 4 shows a second embodiment of a flame protection hood according to the invention in a side view
- FIG. 6 shows a schematic representation of a sealed seam in a first embodiment in a section
- Fig. 7 is a schematic representation of a sealed seam in a second embodiment in a section.
- FIG. 1 to 3 show a first embodiment of a flame protection hood which has a head region 1, an adjoining collar region 2 and an upper body region 3 adjoining the collar region 2. It is shown in the intended use position in the figures, which it assumes when it is attracted to the wearer. The head of the wearer is accordingly arranged in the interior of the head region 1, and his face protrudes through a face opening 11 of the head region 1.
- the collar area
- the upper body region 3 is saddle-shaped and has cutouts for the shoulders of the wearer, as well as a breast bib 31 and a back bib 32, which are arranged on the breast or on the back of the carrier.
- the flame protection hood is preferably put on first and then a protective jacket.
- the protective jacket at least partially covers the upper body area 3, so that the neck and upper body area are jointly protected from potentially dangerous particles by the protective jacket and the flame protection hood.
- the collar area 2 is essentially shaped as a hollow cylinder, an elastic pulling area 4 being arranged approximately at a medium height on the sides, that is to say above the shoulders of the wearer, and on the rear side, that is to say in the neck of the wearer.
- the circumference of the collar area 2 widens first and the pull areas 4 go into a tensioned position and expand. If the collar area 2 sits at the level of the neck of the wearer after being pulled down further, the pull areas 4 adapt to the reduced circumference of the neck and move into a more relaxed position.
- the embodiment shown has a three-layer structure.
- An outer carrier layer 5 faces the environment, while an inner carrier layer 7 faces the carrier.
- a filter layer 6 is arranged in between, which is permeable to gases and particles with a size of less than 1 pm.
- the inner carrier layer 7 and the filter layer 6 extend essentially over the entire outer carrier layer 5.
- the filter layer 6 is a filtering membrane with a porous structure, as a result of which essentially no particles, but air and other small-molecule gases, pass through the membrane can.
- the filter layer 6 is designed to filter out polycyclic aromatic hydrocarbons (PAHs) and to protect the user of the flame protection hood from them. This enables the wearer to be protected from substances harmful to health, but at the same time the flame protection hood remains breathable.
- PAHs polycyclic aromatic hydrocarbons
- Each traction area 4 has two rubber bands 41 arranged one above the other. These elastic bands 41 are sewn to an outer carrier layer 5 in such a way that in a relaxed position, that is to say as shown in the figures, they pull together the circumference of the collar region 2 of the outer carrier layer 5.
- the tension areas 4 are arranged at substantially the same height, a uniform reduction in the circumference of the collar area 2 on the sides and in the rear area of the flame protection hood is achieved, while the area in front of the wearer's throat remains essentially unfolded. They are arranged on the inside, that is to say on the side of the outer carrier layer 5 facing the filter layer 6.
- the first embodiment has two edge sections, a second edge section 200 around the face opening 11 and a first edge section 100 at the lower end of the chest area 3 around the neck opening 20, which has the inner carrier layer 7, outer carrier layer 5 and filter layer 6 connect with each other.
- the carrier layer 5 is at least partially pierced, which leads to a special one stable connection.
- it does not damage the filter property of the filter layer 6, since the edge areas are not completely sealed anyway due to the openings. Otherwise, the filter layer of this embodiment has no sewings to the carrier layers 5, 7.
- the outer carrier layer 5 is composed of a total of five filter cut parts, which can be easily cut individually from fabric or knitted fabric and are sewn to one another via connecting seams 22. In other embodiments, more or fewer filter cut parts can be used. If they are sewn together, the three-dimensional shape results, which is adapted to the body of the wearer.
- the filter layer 6 or the inner carrier layer 7 can also be implemented in the same or similar manner.
- FIGS. 4 and 5 The embodiment shown in FIGS. 4 and 5 is very similar to the first embodiment, so only the most important differences are dealt with here.
- the filter layer 6 extends over the inner surface of the outer carrier layer 5, but it is recessed in a back region 12, ie it is free of the filter layer 6.
- the filter layer 6 is designed such that it has a round opening 13 in the back of the head 12. It is designed in such a way that, in the intended, tightened position on the head, it extends approximately from the top of the head, ie from the uppermost point of the wearer's head, to approximately the border of the parietal bone and occiput. Accordingly, the opening 13 lies approximately above the parietal bone.
- a third edge section 300 is formed, which extends around the opening 13 and in which seams between the filter layer and at least one of the carrier layers can be provided.
- the second embodiment does not have an upper body region 3, but ends after the collar region 2.
- the traction regions 4 are arranged in the region of a neck opening 20.
- the flame protection hood can be arranged above a protective jacket 21, which is correspondingly put on and closed in front of the flame protection hood.
- the tension elements 4 thus seal the connection between the collar area of the protective jacket 21 and the collar area 2 of the flame protection hood by the tension areas 4, so that no particles can penetrate through the neck opening 20.
- This flame protection hood is suitable for being arranged outside a collar area of a jacket. Accordingly, the jacket can first be put on and closed and then the flame protection hood put on the. It is advantageous if the flame protection hood has a neck opening which is delimited by a collar area.
- the filter layer 6 has a first filter cut part 6a and a second filter cut part 6b, which protrude from one another in the region of their edges and are connected there by a filter seam 6c.
- the area of the filter seam 6c and the transition area between the filter cut parts 6a, 6b is covered with an adhesive tape 14 designed as an adhesive strip.
- the adhesive tape 14 is welded to the filter cut parts 6a, 6b, with which the filter seam 6c is sealed.
- the majority of the filter cut parts 6a, 6b together form a continuous, filtering barrier between the inner and outer carrier layers 5, 7, through which no particles larger than 1 ⁇ m can pass.
- the filter seam 6c is arranged near the end of the second filter cut part 6b, with which the first filter cut part 6a forms a seam flag 15 between its end and the filter seam 6c.
- This seam flag 15 is not part of the filtering barrier, as a result of which the perforation does not result in undesired through openings for particles.
- the outer carrier layer 5 likewise has a first outer cut part 5a and a second outer cut part 5b, these protruding at their edges.
- the area of the projection is essentially at the level of the seam flag 15 or the filter seam 6c.
- the outer cut parts 5a, 5b are also sewn together via an outer seam 16, the outer seam 16 also being sewn to the seam flag 15. This enables a flexible but stable connection that does not open the filtering barrier.
- a seam can also be provided, which only connects the outer carrier layer 5 to the seam lug 15, independently of an outer seam 16 connecting the outer cut parts 5a, 5b.
- the inner carrier layer 7 likewise has a first inner cut part 7a and a second inner cut part 7b, which are arranged so as to overlap in the region of the edges and are sewn together. The area of the overlap is offset from the filter seam 6c.
- FIG. 7 shows a second embodiment of a seam connection, the filter seam 6c being so far away from the edges of the first and second filter cut parts 6a, 6b that a seam flag 15 passes through both a part of the first and the second filter cut part 6a, 6b is formed.
- the parts of the first and second filter cut parts 6a, 6b forming the seam flag 15 are approximately of the same length.
- the adhesive tape 14 is not arranged directly above the filter seam 6c, but covers only a gap 17 which arises in the transition area of the filter cut parts 6a, 6b.
- the outer cut parts 5a, 5b are arranged similarly to the filter cut parts 6a, 6b, so that the parts of the outer cut parts 5a, 5b projecting beyond the outer seam 16 form a carrier seam lug 19 which is connected to the seam lug 15 via a connecting seam 18.
- the seam that connects the first inner cut part 7a and the second inner cut part 7b is arranged at the level of the seam tab 15.
