    EMERGENCY HOOD DEVICE The invention relates to an escape bonnet device according to claim 1.
    An escape hood or fire escape hood is a protective hood made of coated fabric, for. B. made of plastic-coated textiles, or flame-retardant plastic, each with a flexible integrated viewing window and a (multi-range) filter integrated into the escape hood. The escape hood is worn over the head and used primarily by the fire brigade in smoky areas, e.g. B. in burning buildings.
    The filter prevents the penetration of toxic fire secondary products (gases, vapors, soot) and also carbon monoxide inside the escape hood, which are released in the event of a fire and can lead to fatal smoke gas poisoning. The protective effect against carbon monoxide (CO) is achieved by a catalytic filter, in particular hopkalite, which catalyzes the oxidation of CO with atmospheric oxygen to CO 2 . The escape hood is therefore a self-contained breathing apparatus (escape filter device) that filters out toxic gases from the air.
    Unlike compressed air powered respirators, an escape hood does not protect against lack of oxygen in the ambient air. However, there are also escape hoods to which an SCBA can optionally be connected. Due to the overpressure then generated in the escape hood, it does not have to be completely closed to the wearer. This also enables a person to be rescued to be supplied with fresh breathing air.
    Typically, the escape hoods are packed and carried and only unpacked and put on when necessary. Packaging made of cardboard or cardboard, barrier bags and vacuum packaging made of aluminum are known in the prior art. The escape hoods packaged in this way are accommodated in a (belt) holster so that they can be carried comfortably.
    A disadvantage of the use of cardboard or cardboard is that it is damaged in contact with moisture. The customer often disposes of the escape hood after only one contact with water for fear of mold. In addition, with cardboard packaging there is no adequate protection against the ingress of dust and soot. Another disadvantage is the large-volume and rigid geometry of the cardboard.
    The problem with the barrier bags, especially the vacuum packaging made of aluminum, is that no visual inspection of the escape hood is possible without destroying the packaging. Injuries to the barrier bag are often only recognized late. This means that if the barrier bag is damaged, the filter is damaged, so that in an emergency the full or no filter performance is no longer available. On the one hand, the filter interacts with gases so that it works as a filter. On the other hand, the filter material is enriched with moisture, which reduces its performance. To determine damage, one helps in practice with a test of the water vapor permeability of the barrier bag, z. B. by weighing. However, this is technically complex and expensive.
    The object of the invention is therefore to provide an escape hood device with an escape hood in a protective cover, the protective cover reliably packing the escape hood up to its use, and a simple test of the escape hood being possible. The escape hood device should be compact, light, soft and inexpensive. In addition, the escape hood should be as comfortable, intuitive and quick to use as possible in an emergency.
    Main features of the invention are specified in the characterizing part of claim 1. Refinements are the subject of claims 2 to 12.
    In an escape hood device with an escape hood in a protective cover, the escape hood being a flexible hood with an integrated, flexible viewing window and a

    Having a filter, the filter having a filter inlet opening which is arranged on the outside of the flexible hood and a filter outlet opening which opens into the interior of the flexible hood, the invention provides that the protective cover is connected to at least one filter plug, the or the filter plugs can be pulled out into the filter and block the activation of the filter.
    The advantage of this is that the filter performance does not decrease even if the protective cover is damaged. This is reliably prevented by the filter plug. Blocking the activation of the filter is to be understood as preventing any reduction in performance of the filter which is based on active filter processes or chemical filter reactions. A functional separation between protection against dust and moisture of the entire escape hood by the protective cover and protection of the filter by the filter plugs is thus achieved. The filter plugs should release the activation of the catalyst when it is pulled, especially when it is pulled out of the filter. Extensive tests for damage in the protective cover to check the filter condition can be omitted. Furthermore, the flexible hood should be made of a coated fabric, e.g. B. made of plastic-coated textiles, or flame retardant plastic. These materials are light and can be stowed away compactly.
    The connection of the protective cover with the filter plug or plugs ensures that the latter can be pulled out of the protective cover without additional handles when it is removed. A variant of the escape hood device therefore provides that the filter plug or filters release the activation of the filter when the escape hood is pulled out of the protective cover. Accordingly, it is easy and intuitive to operate with, to a certain extent, automatic activation of the filter when it is removed from the protective cover. At the same time, the connection and thus the escape hood device as such can be produced inexpensively.
    According to a more detailed embodiment of the escape hood device, it is provided that the filter plug or plugs close the filter inlet opening and the filter outlet opening in a gas-tight manner. This protects the filter media inside the filter from external influences, in particular from air and liquid ingress.
    An embodiment of the escape hood device is particularly preferred, in which two filter plugs are provided, one of the filter plugs being arranged in the filter inlet opening, which forms a plug seat for this filter plug, and wherein this filter plug can be pulled out in the direction of the outside of the flexible head cover, and wherein the other filter plug is arranged in the filter outlet opening, which forms a plug seat for this filter plug, and wherein this filter plug can be pulled out towards the interior of the flexible hood. This specifies simple and intuitive directions of pull. The escape hood is preferably packed in the protective cover such that the neck opening is arranged radially around the filter. This means that the inner valve plug is exposed during removal and can be easily removed.
    The filter plugs should each be connected to the protective cover with a drawstring. Preferably, one drawstring is longer than the other, so that first one of the valve plugs is pulled out and then, especially after manual adjustment of the pulling direction, the second valve plug. This prevents the valve plugs from getting caught in the hood. In addition, the reduction to a few, in particular a single, pulling direction for pulling out the valve plugs is easy to handle.
    A particularly simple removal of the plugs succeeds if one or both valve plugs have a flat plastic plate on the outside as a fastening means, to which the drawstring is fastened. As a result, the lever arm is larger in order to detach the valve plug from the plug seat. In addition, the plastic plate can be used as a grip even with gloves in order to directly grip and pull out the valve plug.
    [0017] The filter plugs are preferably disc-shaped and have a circumferential groove. The result is a flat, compact structure. The plastic plates can also be placed flat on the filter

    Kterreichisctiti palpriar.i housing arranged.
    In a special embodiment of the escape hood device, the filter has a catalyst and the filter plug (s) block the activation of the catalyst. Catalysts are particularly sensitive and lose their filter performance when they come into contact with air. In addition, catalysts become saturated with moisture, which can drastically reduce filter performance.
    In an optional variant, the catalyst is a hop kalite. This enables the conversion of toxic carbon monoxide (CO) to the relatively harmless carbon dioxide (CO 2 ) through (atmospheric oxygen (O 2 ) through oxidation. Hopkalite is the name for mixed catalysts that consist in particular of manganese dioxide and copper (II) oxide In addition, they can contain other metal oxides, for example cobalt oxides and silver (I) oxide, and compositions are, for example, 60% MnO 2 /40% CuO or 50% MnO 2 /30% CuO / 15% CoO and 5% Ag 2 O. In addition Hopkalite catalyze the oxidation of various organic compounds at elevated temperatures (200-500 ° C).
    Preferably, the filter or the catalyst are designed to be exchangeable. As a result, the escape hood can be economically restored to a functional state after use or after the expiry of the minimum durability.
    [0021] Optionally, the filter can have a particle filter. This prevents the inhalation of dirt and soot particles. To protect an optional catalytic converter, it is advisable to connect the particle filter upstream of the catalytic converter from the outside into the interior of the flexible head cover. In particular, the particle filter can have a filter paper. Ring filters are particularly suitable as particle filters.
    Furthermore, a more detailed embodiment of the escape hood device provides that the protective cover is connected to the filter plug or plugs via at least one drawstring. The drawstring enables the user to recognize the direction of pull on the valve plug and to pull the valve plug in the optimal direction. In addition, removal of the escape hood from the protective cover and packaging of the escape hood with the protective cover are conveniently made possible, which makes production or a filter change simple. The drawstring is preferably made of TPU (Desmopan).
    So that the protective cover can be closed tightly, the connection between the protective cover and the filter plug or filters should lie inside the protective cover.
    A particularly long-lasting and tight protection of the filter is achieved in a special embodiment, according to which the filter plug or plugs consist essentially or completely of butyl. In particular, butyl plugs prevent moisture penetration. In this way, a minimum shelf life of 6-8 years can be achieved.
    [0025] In a special design of the escape hood device, the protective cover is a flexible protective bag. It is compact, light and adapts to the content and the environment. Accordingly, it does not cause pressure pain and is not damaged even when subjected to external forces.
    The protective cover is preferably welded. This makes it particularly tight against dust particles and moisture.
    According to a special embodiment, the protective cover is a plastic cover, preferably based on film. Plastic sleeves prevent dust particles and moisture from penetrating particularly well and permanently.
    In order to enable a visual inspection of the escape hood, it is provided in a special variant of the escape hood device that the protective cover is transparent.
    [0029] Furthermore, in a more detailed embodiment, it is provided that the protective cover has a pressure compensation valve. This enables pressure equalization and the protective cover does not inflate and does not burst even at high temperatures. For this purpose, the pressure compensation valve should be a one-way valve that prevents fluid, in particular gas, from flowing out of the
    3.13
    AT16405U1 2019-09-15
    Kterreichisctiti palpriar.i
    Protective cover allowed.
    [0030] The pressure compensation valve is preferably a pressure relief valve. As a result, pressure equalization takes place only from a defined pressure and the pressure relief valve particularly reliably prevents undesired inflow of gas or moisture into the protective cover.
    An addition to the escape hood device provides that the escape hood with the protective cover is removably arranged in a fireproof holster. The holster protects the protective cover and the escape hood inside from flames. It also allows the escape hood to be carried comfortably in the protective cover. The holster preferably protects the protective cover from contact with, in particular, sharp-edged objects. For this purpose, the holster preferably consists essentially of nylon. According to a special design, the holster has a lockable receiving space for the escape hood in the protective cover. This protects the protective cover all around and the escape hood cannot fall out of the holster.
    In a more detailed embodiment, the escape hood has an inner mask which can be placed over the mouth and nose and is airtight, the filter opening out through the filter outlet opening and through the inner mask. The position of the escape hood can be found correctly with the inner mask. In addition, the breathing air is fed directly through the filter. The easy penetration of gases into the escape hood is not critical. Comfortable breathing during long periods of use is achieved if the inner mask has an exhalation valve. This should in particular lead past the filter. This means that the air resistance of the filter cannot be overcome when exhaling. In addition, the filter performance of the filter is not reduced by the exhaled air. To prevent carbon dioxide from accumulating inside the escape hood, the exhalation valve should open on the outside of the flexible hood.
    So that the escape hood can be packed compactly, adapts to the wearer's head and channels the breathing air, the inner mask should have a rubber layer. A high level of comfort is achieved if an additional fabric layer is provided.
    Furthermore, the handling of the escape hood is particularly simple if an elastic banding is provided. This should in particular be connected to the inner mask and pass behind the head. A further elastic banding is preferably provided in the neck area in order to prevent smoke and soot from penetrating. If the strap is designed as an inner strap, it is protected inside the escape hood from external influences such as heat.
    A further optional addition to the escape hood can consist in a compressed air connection which opens into the flexible head hood. When an SCBA is connected, there is overpressure in the escape hood and it does not have to be completely closed to the wearer. This also enables a person to be rescued to be supplied with fresh breathing air. For this purpose, the compressed air connection should open into the inner mask in particular. A pressure relief valve is preferably arranged in the compressed air connection so that nothing can penetrate if no compressed air breathing apparatus is connected.
    Further features, details and advantages of the invention emerge from the wording of the claims and from the following description of exemplary embodiments with reference to the drawings. Show it:

    Kterreichisctiti palpriar.i [0042] An escape hood device 1 can be seen in FIG. 1 in a schematic side view. An escape hood 10 is shown in a half-removed position relative to a protective cover 50. The escape hood device 1 thus has an escape hood 10 which was originally or in a stored state in the protective sheath 50 shown (cf. FIG. 5), but as shown in FIG. 1 is pulled out of the latter. The escape hood 10 is still partially folded. With the exception of this difference in arrangement, the description of FIG. 1 also applies to FIG. 5.
    In addition, the removed and unfolded escape hood 10 is shown in more detail in Figures 2 and 3, namely in Fig. 2 in a side view with partial sections and in Fig. 3 in a frontal view. The statements relating to FIG. 1, which relate to the escape hood 10, apply accordingly to FIGS. 2 and 3.
    1, 2, 3, 5, the escape hood 10 has a flexible head hood 11 with an integrated, flexible viewing window 12 and a filter 20.
    FIG. 4 shows a frontal view of the filter 20 and the statements relating to FIG. 1, which relate to the marked features of the filter 20, apply accordingly to FIG. 4.
    As can be seen in FIGS. 1, 2, 3, 4, 5, the filter 20 has a filter inlet opening 15, which is arranged on the outside 17 of the flexible hood 11, and a filter outlet opening 16 (only in FIG. 1 and 2), which opens into the interior 18 of the flexible hood 11 (see FIG. 2). The filter inlet opening 15 and filter outlet opening 16 are in particular formed in a filter housing 23 in which a catalytic converter 19 is arranged. The catalyst 19 is a hop kalite. In addition, the filter 20 contains a particle filter 14 with a filter paper. This is designed as a ring filter. The particle filter 14 is connected upstream of the catalytic converter 19 from the outside 17 into the interior 18 of the flexible head cover 11.
    The flexible hood 11 according to FIGS. 1, 2, 3, 5 consists either of a coated fabric, for. B. made of plastic-coated textiles, or flame retardant plastic. An elastic strap 32 is incorporated into the flexible head cover 11 (cf. FIG. 2). With this, the escape hood 11 can be placed firmly on the head, so that the mouth, nose and eyes are correctly positioned relative to the escape hood 11. A further elastic band 33 is provided according to FIGS. 2, 3, 5 around a neck opening 13 in the flexible hood 11. The straps 32, 33 are each designed as inner straps, i.e. they are protected from flames on the inside of the flexible hood 11.
    2 that the escape hood 10 has an inner mask 30 which can be placed over the mouth and nose and is airtight. The filter 20 opens out through the filter outlet opening 16 and through the inner mask 30 into the interior 18 of the escape hood 10. The inner mask 30 has an airtight rubber layer and a fabric layer. At least one strap 32 is attached to the inner mask 30 and guided around behind the head area (cf. FIG. 2).
    In addition, the inner mask 30 according to FIGS. 1, 2, 3 and 5 has an exhalation valve 31 which leads past the filter 20 and opens out on the outside 17 of the flexible head cover 11. In particular, the exhalation valve 31 points geodetically downwards when the wearer is in a normal upright position. In this way, accumulating liquid can also be drained off.
    The filter inlet opening 15 forms a plug seat 24 for a filter plug 21. This filter plug 21 can be pulled out in the direction of the outside 17 of the flexible head cover 11. 1 and 2, the filter outlet opening 16 forms a plug seat 25 for a second filter plug 22. The second filter plug 22 can be pulled out toward the interior 18 of the flexible hood 11. In this position, the two filter plugs 21, 22 block the activation of the filter 20, in particular the catalytic converter 19, by closing the filter inlet opening 15 and the filter outlet opening 16 in a gas-tight manner. For this purpose, the filter plugs 21, 22 consist of butyl.

    Kterreichisctiti palpriar.i As can be seen in the partial section in Fig. 1, the filter plugs 21, 22 are each disc-shaped and formed with a circumferential groove. The result is a flat, compact structure. On the outside, the filter plugs 21, 22 each have a fastening means 26, 27, to which a tension band 51, 52 is fastened, and which is designed as a flat, round plastic plate. These plastic plates extend flat over the filter housing 23.
    1 and 5, the drawstrings 51, 52 are connected to the protective sheath 50. 1, a drawstring 52 is longer than the other drawstring 51, so that first the valve plug 21 with the shorter drawstring 51 is pulled out and then, especially after manual adjustment of the pulling direction, the second valve plug 22
    As can be seen in FIGS. 1, 5, the protective cover 50 is connected via the two drawstrings 51, 52 to a filter plug 21, 22 each. In the starting position according to FIG. 5, the connection between the protective cover 50 and the filter plug 21, 22, namely the drawstrings 51, 52, lies inside the protective cover 50. The drawstrings 51, 52 are long enough according to FIG. 1 that the escape hood 10 can be pulled completely out of the protective cover 50 without the tension straps 51, 52 being subjected to tensile stress.
    If the escape hood 10 as shown in FIG. 1 is pulled further out of the protective cover 50 or away from it, the filter 20 is activated by pulling the filter plugs 21, 22 by means of the drawstrings 51, 52, until these are removed from their respective plug seats 24, 25. They then hang on the protective cover 50 and can be left at the place of use.
    The protective cover 50 according to FIGS. 1 and 5 is in each case a flexible protective bag. This consists of transparent plastic or transparent plastic film and is welded shut according to FIG. 5 and opened according to FIG. 1, for which purpose a tear corner 54 is provided (see FIG. 5). A pressure compensation valve 53 is integrated in the protective cover 50, which allows a fluid, in particular gas, to flow out of the protective cover 50. In particular, it is a one-way and a pressure relief valve. It should be noted that the protective cover according to FIG. 5 can also be made significantly smaller. For this purpose, the flexible parts of the escape hood 10 would have to be put together more strongly.
    The invention is not limited to one of the above-described embodiments, but can be modified in many ways.
    [0057] Among other things, the escape hood 10 with the protective cover 50 can be removably arranged in a refractory holster. This holster can be equipped with a belt fastener, e.g. a belt loop or a clip. The holster preferably consists essentially of nylon. The holster should form a lockable receiving space for the escape hood in the protective cover.
