Flame resistant hood

Abstract

The invention relates to a firefighting hood having at least one outer carrier layer (5) and at least one inner carrier layer (7), wherein a filter layer (6) for filtering particles from the air is arranged between the outer carrier layer (5) and the inner carrier layer (7). The invention addresses the problem of providing a firefighting hood that allows as short a preparation time as possible while protecting the wearer effectively. This is achieved in that the filter layer (6) has at least two interconnected filter blanks (6a, 6b), which are stitched together at least partially via at least one filter seam (6c), and in that the connection between the filter blanks (6a, 6b) is at least partially sealed off, wherein the outer carrier layer (5) has, at least in the collar region (2), in the unloaded state, a smaller cut than the filter layer (6).

Description

[0001] The invention relates to a flame-resistant hood according to the preamble of claim 1.

[0002] The primary function of fire-resistant hoods is to protect the wearer – usually firefighters – from the effects of heat and fire. They are used particularly during firefighting operations where breathing apparatus is worn.

[0003] The outer and inner support layers are usually made of a soft and stretchable fiber or textile product such as a woven or knitted fabric, such as fire-resistant textile fibers (e.g., Kevlar or aramids) or other fabrics, and at least partially perform the task of thermal insulation.

[0004] Since contact with potentially harmful pollutants, such as fine particles and other substances, is often unavoidable during such operations, flame-retardant hoods with filter layers are commonly used. These layers prevent the substances, which typically consist of fine particles in the millimeter and micrometer range, from penetrating the hood and contaminating the wearer's skin. These filter layers are usually less elastic than the hood's supporting layers.

[0005] A disadvantage of these fire-resistant hoods is that the poor elasticity of the filter layer prevents them from being cut tightly, resulting in a poor fit. Particularly around the neck, this creates large gaps between the wearer's neck and the hood. This leads to reduced comfort and also causes the hood to slip, making it difficult to put on other clothing. This, in turn, increases the preparation time required for firefighters before they can respond to an emergency. Since the vast majority of deployments are acute emergencies, minimizing preparation time is of paramount importance.

[0006] Additionally, when the hood is pulled tight, the layers can shift against each other, reducing the protective effect and requiring time-consuming readjustment and sorting of the layers. Therefore, the filter layer is often sewn or quilted to at least one backing layer to ensure a stable bond between the backing and filter layers. However, this creates openings in the filter layer, especially when the seams stretch, allowing particles that would otherwise be filtered out to pass through.

[0007] EP 1 308 186 A2 describes a protective suit with a hood, which has seams between a filter layer and the carrier layers. To allow a person to put on the suit, it is very loose-fitting and has a waist belt to compensate for its excessive size.

[0008] WO 2018129195 A1 discloses a protective hood with a filter layer, wherein the filter layer comprises several parts that are sealed together. This prevents particles from passing through the seams of the filter layer parts to the hood's wearer and allows for a more complex, three-dimensional structure of the filter layer to be shaped more effectively. This enables a shape that fits the wearer's head and neck area. However, the problem remains that the filter layer has low elasticity, necessitating a very large neck area for the protective hood, which results in a less than perfect fit.

[0009] US Patent 2011 / 167547 A discloses a stretchable material that provides protection against chemical exposure. It consists of an elastic base material to which a protective film is selectively bonded in strips. The protective film is cut larger than the base material, allowing the base material to stretch without mechanically stressing the protective film. A disadvantage of this solution is that the bonding can lead to a local reduction in the protective effect, and that the base material can only stretch freely in one direction, perpendicular to the adhesive strips. Flame-retardant hoods with an inherently three-dimensional shape cannot be satisfactorily manufactured using this method.

[0010] The object of the invention is therefore to provide a flame-resistant hood that allows for the shortest possible preparation time while providing good protection for the wearer, and at the same time is adapted as well as possible to the body shape of the wearer.

[0011] This problem is solved according to the invention by the features of claim 1. It is provided that the outer support layer has a smaller cross-section than the filter layer, at least in the collar area, when unloaded.

[0012] By dividing the filter into several sections, the shape of the relatively inelastic membrane can be better adapted to the complex three-dimensional shape of the flame-retardant hood. However, the resulting perforations or openings in the membrane pose a risk of harmful substances and particles penetrating it. This can be prevented by sealing, thus keeping the filter layer intact and ensuring its filtering function is not impaired. Preferably, the entire connection between the filter sections is sealed.

[0013] Sealing in this context means that no substances can pass through the connection that cannot also pass through a continuous part of the membrane. However, the seal can also impede the passage of substances that would otherwise be able to pass through continuous parts of the membrane.

[0014] It is also advantageous if the flame-resistant hood has a neck opening that is separated by a collar area. A back or chest flap should not be included.

[0015] It can also be advantageous if a flame-retardant hood has a collar area with a contact surface on its inside to fit against the collar of a protective jacket. This allows the flame-retardant hood, which is put on over a jacket, to connect with the collar area above the jacket's collar, providing complete protection for the neck.

[0016] It is particularly advantageous if the collar area is designed to be positioned outside the collar of the wearer's jacket when the hood is worn. This is especially beneficial for shorter versions without a back or chest bib. The collar area can then close against the jacket collar, creating a tight seal against contaminants such as airborne particles, without requiring the fire-resistant hood to be put on before or after fastening the jacket. This increases the comfort of firefighters, who can then put on the fire-resistant hood at a later time.

[0017] The filter layer can be made, for example, from microporous PTFE (polytetrafluoroethylene), polyester or PU (polyurethane).

[0018] The filter layer is designed to consist of at least two filter sections, which are at least partially sewn together via at least one seam. This allows the filter layer's shape to be optimally adapted to the wearer's head and upper body shape. This also simplifies the manufacturing process, as flat filter sections can be cut and then sewn together.

[0019] The connection between the filter sections is at least partially sealed. This prevents the unwanted penetration of particles through the connection. The seal should be sufficiently tight to allow only particles or substances of a size or type that can also pass through continuous sections of the filter layer to pass through. The seal can be made of the same material from which the filter layer is primarily composed.

[0020] This can be achieved by using an adhesive tape to seal the joint between the filter sections, preferably welded to the filter sections. The adhesive tape can be fixed to the filter sections with its adhesive side and welded to them, for example, by hot air welding or ultrasonic welding.

[0021] In a preferred embodiment, the filter layer has at least two filter sections which are welded together. This represents a secure type of connection that particles cannot penetrate.

[0022] Furthermore, adhesive tape can seal the joint between the filter sections. Preferably, the adhesive tape is welded to the filter sections.

[0023] It is also particularly advantageous if the filter seam is at least partially sealed. Sealing the seam prevents the risk of the support layer being perforated by the seam, allowing particles to pass through unintentionally.

[0024] Accordingly, it is particularly advantageous if an adhesive tape is applied to the seam of the filter layer, preferably welded to the filter layer. This allows the seam to be made first, followed by the application of the sealing tape. This also allows larger holes resulting from the sewing process to be closed. If the adhesive tape is made of the same material as the filter layer components, it can bond permanently and effectively to them.

[0025] Preferably, the flame-retardant hood has a face opening, and the face opening extends to a forehead area to expose the wearer's forehead when the hood is worn. This is particularly useful when using respiratory masks such as two-point masks, which otherwise cannot fit snugly against the forehead and create a proper seal. The face opening of the flame-retardant hood preferably extends to just above the mask when worn, so that as little facial skin as possible remains exposed.

[0026] It is intended that the filter layer has at least two interconnected filter sections, which are at least partially sewn together via at least one filter seam, and that the connection of the filter sections is at least partially sealed.

[0027] Furthermore, the filter layer may be designed so that its edges are at least partially sewn to the outer or inner support layer, or both. This ensures that the filter layer is sufficiently firmly bonded to the other layers, making quilting or other widespread seams unnecessary. This maintains the filtering capacity across the entire surface of the filter layer without compromising comfort or making it more difficult to put on.

[0028] Edge sections refer to the boundary areas of the filter layer, i.e., its edges and corners. These ends or cut edges are typically found around openings through which, for example, the user's neck or face passes. If certain areas of the flame-retardant hood lack a filter layer, these are also defined by edge sections.

[0029] The edge areas are therefore usually strip-shaped areas that extend along an edge of the filter layer.

[0030] It is particularly advantageous if at least one surface section is arranged between the edge sections, which is essentially free of seams with the outer or inner support layer. It is especially 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-resistant hood. Preferably, the surface section extends over a large proportion of the filter layer's surface.

[0031] The design may also include occasional stitched sections between the surface segments, preferably with sealed seams. This is particularly unproblematic in areas that are not very exposed, such as the back of the head, which is usually covered by the firefighter's helmet.

[0032] It is particularly advantageous if the filter layer, except for the edge sections, is essentially free of seams with the outer or inner support layer. It is especially advantageous if, except for the edge sections, the filter layer is free of seams with the support layers.

[0033] Furthermore, it may be provided that the flame-resistant hood has a first edge section around a neck opening of the flame-resistant hood and a second edge section around a face opening of the flame-resistant hood.

[0034] If the flame-retardant hood is designed to have a chest bib and a back bib, with the chest bib being longer than the back bib, this prevents the back bib from folding uncomfortably when putting on a jacket after donning the flame-retardant hood. At the same time, adequate neck protection is ensured. Preferably, the back bib extends only over the user's neck when the hood is worn and seals this area with a jacket.

[0035] It is also advantageous if the filter layer has at least two filter sections that form a connection that is essentially impermeable to particles. This ensures that no particles can pass through the filter layer via the connection. The permeability of the filter layer to water vapor may be reduced in these areas, but this is not a problem because the remaining areas of the filter layer provide sufficient ventilation.

[0036] It is particularly advantageous if the filter layer has at least one seam flap that is connected to at least one support layer. This allows for a dense filter layer while ensuring a stable connection between the layers. This prevents unwanted shifting between the layers. The filter layer no longer needs to be connected to the support layers via seams that penetrate the filter layer. The seam flap connection is more flexible and adapts more easily to deformations of the flame-retardant hood, for example, when pulling it over the head, while still providing a stable connection without unwanted folds or creases. The filter layer can still be connected to the support layers via seams that penetrate it; this is particularly problematic at end points such as a face hole.

[0037] It may be provided that at least the outer support layer is connected to the seam flap.

[0038] It is particularly advantageous if the filter layer sections are sewn together with an overlap at the filter seam, and at least one filter layer section forms at least part of the seam flap. This automatically creates at least part of the seam flap through the sewing process. Alternatively, the seam flap can also be formed by an additional piece of fabric that is sewn together with the filter layer sections. The seam flap formed by the filter layer section can also be extended by adding further pieces of fabric. Alternatively, the seam flap can also be formed by sewing a loop of the filter layer.

[0039] To achieve a particularly flexible connection, the seam flap can be sewn to at least one carrier seam flap of a carrier layer.

[0040] When the adhesive tape is placed on the filter layer, it is both invisible and protected from external influences and damage.

[0041] Furthermore, the design provides for an annular collar area of ​​the flame-retardant hood to have at least one elastic tension zone extending essentially along the circumference of the collar area. This tension zone allows the collar area's circumference to adapt to the wearer's neck thickness once the flame-retardant hood has been pulled over the head. The collar area's circumference is preferably chosen to be large enough so that the head—which typically has a larger circumference than the neck—fits easily through the collar area when the tension zone is stretched. Once the collar area is in place, the tension zone contracts, ensuring a comfortable fit adapted to the neck circumference. This reduces or prevents air pockets between the neck and the collar area. It also reduces the risk of the hood slipping when fully donned.

[0042] The tension area is an area that brings the collar area into a contracted shape in a relaxed position, but allows an elastic enlargement of the collar area when under tension.

[0043] The design stipulates that the outer support layer, at least in the collar area, has a smaller cross-section than the filter layer when unloaded. This difference in cross-section ensures that the filter layer in the collar area, between the seams where it connects to the outer support layer, is larger than the collar area of ​​the outer support layer itself. The circumference of the filter layer in the collar area is therefore larger than the circumference of the outer support layer in the same area. Consequently, when the load is removed, the outer support layer contracts elastically until it reaches a state of unloaded pressure. The filter layer within it then folds.

[0044] The elastic tension section, which preferably includes at least one elastic band, is connected to at least the outer support layer. Additionally, the elastic tension section may also include at least one elastic band connected to the inner support layer. The elastic band can be arranged such that, in its relaxed position, it folds not only the filter layer but also at least one support layer. The term "elastic band" refers to an elastic band that, in its relaxed position, has a specific length and can be stretched to a greater length.

[0045] These flame-resistant hoods usually have a head area, a collar area and an upper body area, which, when worn as intended, are positioned on the head, neck or upper body of the wearer.

[0046] Furthermore, it can be provided that one tensioning area is arranged on each side surface and one on each neck surface, with the tensioning areas being arranged essentially at the same height. This achieves a uniform folding of the collar area, which is comfortable. The height refers to the height along a main axis of the flame-resistant hood, along which the head area, collar area, and upper body area are arranged.

[0047] It is particularly advantageous if all tension areas are designed together to reduce the circumference of the collar area from a fully tensioned position to a relaxed position by at least 5%, preferably at least 30%. If only one tension area is provided, it is correspondingly advantageous if this tension area alone enables a reduction of 5%, preferably 30%.

[0048] Fires often produce tiny particles that pose a health risk. These airborne particles can be carcinogenic. Accordingly, in a preferred embodiment, the maximum penetration size of the filter layer for particles smaller than 2 µm is set. This minimizes the health risk to the wearer while still providing a breathable hood.

[0049] It is particularly advantageous if the filter layer is designed to prevent the passage of harmful substances, preferably polycyclic aromatic hydrocarbons or similar materials. This prevents these toxic substances from coming into contact with the skin of the wearer of the flame-retardant hood. Harmful substances are defined as substances that are harmful to humans and negatively affect the human body, especially those classified as harmful to health under the REACH Regulation (Regulation (EC) No. 1907 / 2006).

[0050] It is particularly advantageous if the back of the flame-retardant hood, which is positioned at the back of the head when properly worn, is free of the filter layer. This means that, when the hood is worn correctly, the back of the head is located in the area of ​​the wearer's parietal bone, i.e., in the cranio-dorsal region of the head, above the parietal lobe of the brain. Since this area is generally covered by the protective helmet during operations, particle exposure is kept to a minimum. Accordingly, the filter layer is not necessary in this area, but omitting it makes it more flexible. This results in a better fit of the flame-retardant hood without significantly increasing the wearer's particle exposure. At the same time, the relatively expensive filter layer is eliminated, leading to more cost-effective manufacturing.

[0051] In this sense, it can also be advantageous to provide protective clothing comprising at least one protective jacket and at least one flame-resistant hood, wherein the protective jacket has a collar and the flame-resistant hood has a collar area, and the collar area is positioned outside the collar when worn as intended. It is particularly advantageous if the flame-resistant hood is a flame-resistant hood according to the invention. When worn, the collar of the jacket extends around the neck of the wearer or user.

[0052] The term "put on" or "put on" refers to a state in which a user, such as a female or male firefighter, is wearing a protective jacket and flame-resistant hood as intended on their upper body or head.

[0053] The present invention will now be explained in more detail with reference to the non-limiting embodiments shown in the figures. These show: Fig. 1 a first embodiment of a flame-resistant hood according to the invention in a front view; Fig. 2 the first embodiment in a side view; Fig. 3 the first embodiment in a rear view; Fig. 4 a second embodiment of a flame-resistant hood according to the invention in a side view; Fig. 5 the second embodiment in a rear view; Fig. 6 a schematic representation of a sealed seam in a first embodiment in a section; Fig. 7 a schematic representation of a sealed seam in a second embodiment in a section.

[0054] In Fig. 1 bis Fig. 3 A first embodiment of a flame-resistant hood is shown, comprising a head section 1, an adjoining collar section 2, and an upper body section 3 adjoining the collar section 2. The figures depict it in its intended position of use when worn by the wearer. Accordingly, the wearer's head is positioned inside the head section 1, and their face protrudes through a face opening 11 in the head section 1. The collar section 2 is positioned at the level of the wearer's neck, while the upper body section 3 essentially covers the upper parts of the wearer's shoulder and upper body area. The wearer is not shown.

[0055] The upper body area 3 is saddle-shaped and has cutouts for the wearer's shoulders, as well as a chest bib 31 and a back bib 32, which are positioned on the wearer's chest and back, respectively. Preferably, the flame-resistant hood is put on first, followed by a protective jacket. The protective jacket covers at least part of the upper body area 3, thus protecting the neck and upper body from potentially hazardous particles through both the protective jacket and the flame-resistant hood.

[0056] The collar area 2 is essentially shaped as a hollow cylinder, with an elastic tension area 4 arranged at approximately the middle height on the sides, i.e. above the shoulders of the wearer, as well as on the back, i.e. in the neck of the wearer.

[0057] When the flame-resistant hood is pulled over the wearer's head, the circumference of the collar area 2 expands first, and the tensioning areas 4 move into a taut position and stretch. Once the collar area 2 is pulled down further and sits at the level of the wearer's neck, the tensioning areas 4 adjust to the reduced neck circumference and relax.

[0058] The illustrated embodiment has a three-layer structure. An outer support layer 5 faces the environment, while an inner support layer 7 faces the wearer. A filter layer 6, permeable to gases and particles smaller than 1 µm, is arranged between these layers. The inner support layer 7 and the filter layer 6 extend substantially across the entire outer support layer 5. The filter layer 6 is a porous filtering membrane, allowing air and other small-molecule gases to pass through while preventing the passage of particles. The filter layer 6 is designed to filter out polycyclic aromatic hydrocarbons (PAHs) and protect the wearer of the flame-retardant hood from them. This protects the wearer from harmful substances while maintaining the hood's breathability.

[0059] Each tension area 4 has two elastic bands 41 arranged one above the other. These elastic bands 41 are sewn to an outer support layer 5 in such a way that, in a relaxed position, as shown in the figures, they tighten the circumference of the collar area 2 of the outer support layer 5. By arranging the tension areas 4 at essentially the same height, a uniform reduction in the circumference of the collar area 2 is achieved on the sides and in the rear area of ​​the flame-resistant hood, while the area in front of the throat of the support remains essentially unfolded. They are arranged on the inside, i.e., on the side of the outer support layer 5 facing the filter layer 6.

[0060] 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 connect the inner support layer 7, outer support layer 5, and filter layer 6. The support layer 5 is at least partially pierced, resulting in a particularly stable connection. However, this does not impair the filtering properties of the filter layer 6, since the edge areas are not completely sealed due to the openings anyway. Otherwise, the filter layer of this embodiment has no stitching to the support layers 5 and 7.

[0061] The outer support layer 5 is composed of a total of five filter sections, which can be individually cut from fabric or knitted material and are sewn together via connecting seams 22. In other embodiments, more or fewer filter sections can be used. When sewn together, they form a three-dimensional shape that conforms to the body of the support. The filter layer 6 or the inner support layer 7 can be constructed in the same or a similar manner.

[0062] The in Fig. 4 and Fig. 5 The embodiment shown is very similar to the first embodiment; therefore, only the most important differences will be discussed here.

[0063] The filter layer 6 extends, as in the first embodiment, over the inner surface of the outer support layer 5; however, it is recessed in a back-of-the-head area 12, which is thus free of the filter layer 6. For this purpose, the filter layer 6 is designed to form a round opening 13 in the back-of-the-head area 12. It is designed so that, in its intended, tightened position on the head, it extends approximately from the vertex of the head, i.e., from the highest point of the wearer's head, to approximately the border between the parietal and occipital bones. Accordingly, the opening 13 lies approximately above the parietal bone.

[0064] Through this opening 13 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 support layer may be provided.

[0065] The second embodiment does not have an upper body area 3, but ends after the collar area 2. Thus, the tensioning elements 4 are arranged in the area of ​​a neck opening 20. This allows the flame-resistant hood to be positioned above a protective jacket 21, which is accordingly put on and closed in front of the flame-resistant hood. The tensioning elements 4 seal the connection between the collar area of ​​the protective jacket 21 and the collar area 2 of the flame-resistant hood, preventing particles from entering through the neck opening 20.

[0066] This flame-retardant hood is designed to be worn outside the collar area of ​​a jacket. Accordingly, the jacket can be put on and fastened first, and then the flame-retardant hood put on. It is advantageous if the flame-retardant hood has a neck opening that is separate from the collar area.

[0067] Fig. 6 Figure 1 shows a first embodiment of a seam connection in detail. The filter layer 6 has a first filter section 6a and a second filter section 6b, which overlap each other at 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 sections 6a and 6b are covered with an adhesive tape 14. The adhesive tape 14 is welded to the filter sections 6a and 6b, thus sealing the filter seam 6c. The majority of the filter sections 6a and 6b together form a continuous, filtering barrier between the inner and outer support layers 5 and 7, through which no particles larger than 1 µm can pass.

[0068] The filter seam 6c is located near the end of the second filter section 6b, so that the first filter section 6a forms a seam flap 15 between its end and the filter seam 6c. This seam flap 15 is not part of the filtering barrier, meaning that its perforation does not create any unwanted passageways for particles.

[0069] The outer support layer 5 also has a first outer cut section 5a and a second outer cut section 5b, which overlap at their edges. The overlapping area is essentially at the level of the seam flap 15 or the filter seam 6c. In the overlapping area, the outer cut sections 5a and 5b are also sewn together via an outer seam 16, which is also sewn to the seam flap 15. This provides a movable yet stable connection that does not open the filtering barrier. Alternatively, a seam can be provided that connects only the outer support layer 5 to the seam flap 15, independently of an outer seam 16 connecting the outer cut sections 5a and 5b.

[0070] The inner support layer 7 also has a first inner cut section 7a and a second inner cut section 7b, which are arranged overlapping at the edges and sewn together. The overlap area is offset from the filter seam 6c.

[0071] Fig. 7 Figure 1 shows a second embodiment of a seam connection, wherein the filter seam 6c is located so far from the edges of the first and second filter sections 6a, 6b that a seam flap 15 is formed by a portion of both the first and second filter sections 6a, 6b. The portions of the first and second filter sections 6a, 6b forming the seam flap 15 are approximately the same length. The adhesive tape 14 is not positioned directly over the filter seam 6c, but only covers a gap 17 that forms in the transition area of ​​the filter sections 6a, 6b.

[0072] 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 that extend beyond the outer seam 16 form a support seam flap 19, which is connected to the seam flap 15 via a connecting seam 18.

[0073] The seam that connects the first inner cut piece 7a and the second inner cut piece 7b is located at the level of the seam flap 15.
