Description

The present invention relates to a protective suit assembly, a protective suit unit and a respiratory protection unit.

Personal protective equipment (PPE) is commonly used to protect people or animals from harmful, such as nuclear, chemical or biological agents. There are many examples of Personal Protective Equipment (PPE) known that can surround a user with a personal shelter, such as chemical protective suits (CSA), protective tents, casualty bags, and the like. These systems isolate parts of the body, preferably the entire body of a user from harmful, such as atomic, biological or chemical agents. In the case of atomic agents, the protection refers to the protection against radiological aerosols, particles and dusts, protection against radiation is largely impossible. Because these agents are often detrimental to the respiration of the person being protected, various types of outside air cleaning or outside air independent air supply systems are used, thus enabling the user to inhale and exhale harmlessly.

• Typ 1a: „Gasdichter“ CS-Anzug mit einer im Schutzanzug getragenen Umgebungsluft-unabhängigen Atemluftversorgung (self-contained breathing apparatus), Abkürzung: SCBA)
• Typ 1b: „Gasdichter“ CS-Anzug mit einer außerhalb getragenen Umgebungsluft-unabhängigen Atemluftversorgung (SCBA)
• Typ 1c: „Gasdichter“ CS-Anzug mit einer Atemluftversorgung mit Überdruck (z.B. aus externen Leitungen)

There are different personal protective equipment (PPE) for dealing with harmful, for example atomic, biological or chemical agents (hazardous substances). These are classified according to certain criteria. The highest level of protection is provided by protective suits of category III (according to 88/686 / EEC). It applies to PPE intended to counteract lethal risks or serious and irreversible damage to health (see BGI / GUV-I 8685) and specifies quality requirements. Furthermore, PSA within category III are divided into different types. Here again the highest protection is provided by PSA of type 1, in particular a gas-tight chemical protective suit (CSA) DIN EN943-1 , For Category III Type 1 horsepower equipment, one also differentiates between the breathing air supply:

• Type 1a: "Gas-tight" CS suit with a self-contained breathing apparatus worn in a suit, abbreviation: SCBA)
• Type 1b: "Gas-tight" CS suit with an outside air-independent breathing air supply (SCBA)
• Type 1c: "Gas-tight" CS suit with a breathing air supply with overpressure (eg from external lines)

The fundamental problem of suits according to type 1a is the rapid exhaustion of the respiratory air supply after a period of about 30 minutes, in particular when using a breathing air container device, for example an oxygen cylinder. This also ends the possible duration of use, for example, a fireman during rescue work, wearing such a suit. Since the breathing air supply is worn inside the suit and represents the sole breathing air supply, it must be used for the approach to the danger area for breathing air supply, including in those areas where a lower respiratory protection would be sufficient. As soon as the consumption of the respiratory air supply begins, so already runs the possible duration of use.

A possibly necessary change of a breathing air cylinder is not easy: The suit would have to be opened for this purpose, whereby the protection against the harmful agents would be repealed. The safe opening of the suit, however, can only be done after a time-consuming decontamination. Such an exchange of a breathing air bottle is therefore possible only outside of the contamination safe.

In the case of a Type 1b suit, it is possible to change the SCBA, for example a breathing bottle, more easily because it is worn outside the suit. However, the contamination risk is also increased here. Complete decontamination is not always possible, so the SCBA must be disposed of. Air conditioning devices may be used, such as air circulation or air regeneration devices instead of breathing air device devices. This can extend a possible use time up to 4 hours or more. Usually, however, the regeneration devices emit such a considerable amount of heat to the air supply that the respiratory air temperature rises sharply, which makes the use of the carrier increasingly difficult and, if necessary, makes a complicated air cooling system necessary. But even the considerable heating of the equipment used itself can be a danger, especially in potentially explosive environments, where, for example, the harmful chemical agents are highly flammable. An increased device temperature can lead here to an ignition of an explosion of chemical agents, which is to be avoided. The use of regeneration devices is therefore the exception rather than the current standard, and is for very specific applications, e.g. Inserts in tunnels etc., suitable.

In the case of a Type 1c CS suit, the limitation of the breathing air supply could be circumvented by allowing the necessary supply of breathing air via a breathing air supply hose that is under overpressure. However, the use of a necessary supply line between suit and air supply source for many Missions unsuitable because the radius of action of the wearer of the CS suit is severely limited.

In addition to the use of a CS suit with SCBA type 1 or type 1b, a CS suit with respirator and filter (APR, short for Air-Purifying Respirator) or respirator and blower protection (PAPR, abbreviation for Powered Air-Purifying Respirator). The combination with APR is possible, but the wearer is heavily burdened because the filter resistance must be overcome with lung force. This is avoided by using a PAPR.

The publication DE 43 44 353 A1 shows a CS suit with a portable air supply. The supply device is worn on the back of the wearer of the protective suit. The supply device is connected to the respirator mask of the CS suit via a breathing air supply hose. The breathing air can be cooled here.

It is an object of the present invention to provide a protective suit arrangement for the protection of persons from harmful, for example. Atomic, chemical and / or biological agents, which avoid the known disadvantages of the above protective suit arrangements with respiratory protective equipment in the form of APR, PAPR and / or SCBA, in particular, can increase the maximum possible residence time of wearers of such protective suit assemblies in a hazard area and improve the reusability of respiratory protective equipment; as well as suitable protective suits and respiratory protection units with respiratory protective equipment.

This object is achieved by a protective suit arrangement and by a protective suit unit and a respiratory protection unit according to the independent patent claims. Advantageous embodiments and further developments of the protective suit arrangement and the protective suit unit and respiratory protection unit are evident from the dependent claims, the following descriptions and the figures.

According to a first aspect, a protective suit arrangement for protecting persons from harmful, in particular atomic, chemical and / or biological agents is given. Harmful chemical agents may be, for example, harmful gases that are released uncontrollably in a chemical accident, but also chemical warfare agents or the like. Biological agents may be, for example, pathogens in the respiratory air, or also biological warfare agents and biological contaminants from industrial companies. Atomic agents can e.g. be released in an accident in a nuclear power plant, but also in terrorist attacks with a so-called "dirty bomb".

The protective arrangement comprises a protective suit unit, for example a chemical protective suit, CSA for short. A suitable protective suit unit typically comprises two leg units with feet, a torso unit, two sleeves with protective gloves attached, and a head unit usually equipped with a respirator. In this way, a person can be fully absorbed in the protective suit unit and act as freely as possible with the protective suit unit in the danger zone.

The individual subdivisions of the protective suit unit may be formed integrally with the tightening unit or may be designed in several parts, but in a fluid-tight manner connected to the rest of the tightening unit. Due to the fluid-tight design of the protective suit unit, which includes gas-tightness, the protective suit unit has a first media barrier, which protects the wearer of the protective suit unit from harmful environmental influences.

Furthermore, the protective suit unit has a first inner space, which as far as possible, ideally completely fluid-tight, can be separated from an outer space which may contain the potentially harmful agents. The barrier of the interior of the protective suit unit in front of the outer space is produced in particular with the protective suit unit cover, for example a special plastic and / or rubber sleeve. If the protective suit unit is designed in several parts, the protective suit unit envelope also includes separation points of the individual subunits of the protective suit unit, which are likewise made fluid-tight, for example by welding or other joining and / or joining methods.

Furthermore, the protective suit unit has a respiratory protection unit in which respiratory protective equipment is accommodated. The respiratory protection equipment is designed to treat the breathing air. As well as for the protective suit arrangement, the respiratory protection unit also has a first media barrier, the respiratory protection unit also has a (second) media barrier, by means of which a second interior of the respiratory protection unit can be separated from the outer space as far as possible in a fluid-tight manner. In this case, the media separation effected in this way takes place by means of a respiratory protection unit envelope, which can be made of the same material as the protective suit unit envelope, for example of a rubber and / or plastic material, or in several parts. In particular, the greatest possible fluid-tight separation of External space through the breathing protection unit cover for the respiratory protection unit as a separate unit on its own, even without a protective suit unit.

In addition, the protective suit arrangement on one or more breathing air hoses, through which the two inner spaces of the protective suit unit and the respiratory protection unit are connected to each other, that this connection represents the only fluidic connection between the two interior spaces and the fluidically connected common interior so largely fluid-tight of the Outdoor space is separate.

Such a two-piece protective suit arrangement can also be referred to as a hybrid protective suit. Due to the independent complete separation of media in the sense of a largely fluid-tight seal to the outside out possible in particular in the presence of harmful, such as atomic, chemical and / or biological agents completely replace the entire respiratory protection unit, without opening the protective suit unit and cancel their media separation.

For example, the exchange can be done with the help of a second person, who goes to a short time in the danger area. The respiratory protection unit to be replaced can then be retrieved from the danger area, decontaminated and reprocessed in a non-contaminated environment, for example refilled.

In an advantageous embodiment, the protective suit arrangement comprises a protective suit unit-outside coupling element and the respiratory protection unit comprises a breathing protection unit-outside coupling element. The protective suit unit outer-side coupling element is attached from the outside to the protective suit unit envelope, either directly or indirectly via a carrier body.

Analogously, the breathing protection unit-side coupling element is also arranged on the outside of the breathing protection unit envelope. The coupling elements allow a mechanical coupling of the protective suit unit with the respiratory protection unit, in particular without interruption of the greatest possible fluid-tight separation of the respective interior spaces from the outside space. Due to the mechanical coupling, the respiratory protection unit can be easily carried by the wearer of the protective suit unit. In particular, the respiratory protection unit can be carried along a backpack, which is coupled to the protective suit unit via the coupling elements.

The protective suit arrangement preferably comprises a respiratory mask, which is either formed on one side with the protective suit unit or as a separate part as far as possible fluid-tightly connected to the rest of the protective suit unit. For example, the respirator may be joined to the rest of the protective suit unit in sealing association therewith, such as by plastic welding or the like.

The at least one breathing air hose of the protective suit arrangement or even a plurality of such breathing air hoses are preferably connected to the respiratory mask.

Advantageously, the respiratory protection unit has a coupling element for the breathing air hose, by means of which it can be coupled with the respiratory protection unit and its respiratory protection equipment in a simple manner so that a fluidic connection is established with the other end connected to the respiratory mask. By the breathing air hose coupling element, for example, by the above assistant person, the coupling and decoupling of new and old respiratory protection unit can be easily performed. In the supply hose, a regulator can be arranged.

Advantageously, the respiratory protective equipment comprises a blower-assisted respirator (PAPR) located in the second interior of the respiratory protection unit or a self-contained breathing apparatus (SCBA), or both. Through these various embodiments, the respiratory protection can be selected in each case adapted to the existing danger situation. In the embodiment of a combined respiratory protective equipment with PAPR and SCBA, the breathing air hose has a switching device. Preferably, this is arranged on the breathing tube or on the respirator, and is for example designed as a control switch, which can be, for example, manually operated by the user. Depending on the danger environment, this can be used to switch between PAPR and SCBA.

In one embodiment, the outside air-independent breathing apparatus SCBA comprises a breathing air bottle, which is arranged in the respiratory protection unit. Such a breathing air bottle usually contains a breathable mixture of air, which is compressed by pressure contained in the bottle and is connected via, for example, an outlet valve system to a regulator, such as the aforementioned regulator in the breathing tube leading to the breathing mask. The fact that the air-gas mixture is under pressure allows the consumer, for example the wearer of the protective suit arrangement, to have a longer duration of time with breathing air be supplied as without pressurization of the gas mixture in the bottle.

In one embodiment of respiratory protective equipment with SBCA self-contained breathing apparatus and blower-assisted respirator, the breathing air bottle may advantageously be attached to the blower-assisted breathing apparatus PAPR, for example, bolted, taped or by double-sided coupling closure.

In one embodiment of a fan-assisted breathing apparatus, the respirator includes a breathing apparatus with at least one breathing air filter, usually several breathing air filters. For easy replacement of this breathing air filter, the respiratory protection unit, in which the respirator is introduced, a penetration, through which a person can reach through and connect the breathing air filter from the outside with the respirator, for example, screw on the respirator or plugged.

In one embodiment, the protective suit assembly of the protective suit assembly has a protective suit unit inner side clutch plate in its (second) interior. This is on the inside either directly attached to the Schutzanzugseinheitshülle, so that direct, cohesive contact of the coupling plate with the Schutzanzugseinheit hull consists or indirectly, so that at least a mechanical fixed connection with the protective suit unit hull.

Similarly, on the outside of the protective suit unit, on the outside of the protective suit unit envelope a protective suit unit outer side clutch plate is arranged. The two coupling plates must be mechanically coupled to each other and may preferably serve as a support frame on the inside, or are connected to a support frame, so that a wearer, the protective suit inside clutch plate can easily carry. In particular, the wearer can attach the support frame, for example via one or more shoulder straps to his upper body, for example in the manner of a backpack. The respirator unit can be fastened to the protective clothing outer side coupling plate, so that the wearer of the protective clothing unit can comfortably carry it.

In order for the protective suit unit outer side clutch plate to be connected to the corresponding inside clutch plate, these two clutch plates are mechanically connected to one another by means of connecting elements. In this case, the connecting elements are passed through at break-through points by the protective suit unit envelope, wherein on both sides of the breakthrough additional sealing means may be attached, which continue to ensure the greatest possible gastightness of Schutzanzugseinheit hull. The sealing means may be, for example, a sealing ring or the like. For example, the connecting elements may be rivets or screws with which the protective suit inside and outside clutch plates are interconnected by the protective suit unit envelope. In this case, the rivets or the screws, preferably with locknut, strengthen the sealing effect of the sealing elements by adhesion.

Analogous to the two coupling plates of the protective suit unit on the one hand in the interior of the respiratory protection unit a Atemschutzeinheits inside clutch plate is arranged, which is arranged on the inside of the respiratory protection unit cover either directly in contact or indirectly to the respiratory protection unit cover. On the other hand, the outside of the respiratory protection unit is also fitted with a coupling plate from the outside on the respiratory protection unit cover. Analogously as in the case of the protective suit unit, the two Atemschutzeinheits-inside and Atemschutzeinheits-outside clutch plates with the same or similar fasteners in the same way largely gas-tight sealing passed through breakthrough points of the respiratory protection unit shell, and here the same fasteners can be used as in the case the protective suit unit.

Preferably, both the respiratory protection unit and the protective suit unit comprise at least one coupling element, a respiratory protection unit outside coupling element and a protective suit unit-side coupling element. Preferably, each of a plurality of these coupling elements may be arranged on the respective outer side clutch plates.

Preferably, with the coupling elements on the outside of the protective suit and on the outside of the respirator unit, the protective suit unit can be mechanically coupled to the respiratory protection unit so that the wearer of the protective suit unit can easily carry the respiratory protection unit, for example in the manner of a backpack as described above.

In an advantageous embodiment, the two clutch plates, both the protective suit unit and the respiratory protection unit made of stainless steel, which is particularly resistant to corrosion and easy to decontaminate. Alternatively, a decontaminatable plastic can be used.

• – eine erste Sperre, durch die ein erster Innenraum der Schutzanzugseinheit möglichst weitgehend fluiddicht von einem Außenraum, der die schädlichen Agenzien enthalten kann, mit Hilfe einer Schutzanzugseinheitshülle trennbar ist,
• – mindestens ein Schutzanzugseinheits-außenseitiges Kupplungselement, das außenraumseitig an der Schutzanzugseinheitshülle angeordnet ist,
• – wobei das oder die Kupplungselemente eine mechanische Kupplung der Schutzanzugseinheit mit einer Atemschutzeinheit ermöglichen, und zwar ohne Unterbrechung der möglichst weitgehend fluiddichten Trennung des Innenraums der Schutzanzugseinheit vom Außenraum. Die Kupplung erfolgt dabei so, dass eine an die Schutzanzugseinheit befestigte Atemschutzeinheit durch die Trägerperson der Schutzanzugseinheit beim Tragen mitgetragen werden kann, insbesondere in der Art eines Rucksacks, beispielsweise mit einem entsprechend innenseitig in der Schutzanzugseinheit angeordneten Tragegestell, das beispielsweise einen oder mehrere Schulterträger aufweist, so dass die Person die Atemschutzeinheit bequem mitführen kann.

According to a second aspect, there is provided a protective suit unit that can be used in a protective suit assembly according to the first aspect. This preferably has the above-mentioned features of the protective suit unit, in particular:

• A first barrier, by means of which a first inner space of the protective suit unit can be separated, as far as possible, in a fluid-tight manner from an outer space, which may contain the harmful agents, with the aid of a protective unit cover;
• At least one protective suit unit outside coupling element which is arranged on the outside of the protective suit unit envelope,
• - Where the one or more coupling elements allow a mechanical coupling of the protective suit unit with a respiratory protection unit, without interrupting the most fluid-tight separation of the interior of the protective suit unit from the outside space. The coupling takes place in such a way that a respiratory protection unit attached to the protective suit unit can be carried by the wearer of the protective suit unit when wearing it, in particular in the manner of a backpack, for example with a carrying frame arranged correspondingly inside the protective suit unit, which for example has one or more shoulder straps, so that the person can easily carry the respiratory protection unit.

• – eine Atemschutzausrüstung zur Aufbereitung der Atemluft,
• – eine zweite Sperre, durch die ein Innenraum der Atemschutzeinheit bereits für sich alleine, d.h. nicht durch Anordnung innerhalb der Schutzanzugseinheitshülle, möglichst weitgehend fluiddicht von dem Außenraum, aber auch von dem Innenraum der Schutzanzugseinheit, mit Hilfe einer Atemschutzeinheitshülle getrennt werden kann,
• – mindestens ein Atemschutzeinheits-außenseitiges Kupplungselement, vorzugsweise mehrere, das bzw. die außenraumseitig an der Atemschutzeinheitshülle angeordnet sind,
• – wobei die atemschutzeinheitsseitigen Kupplungselemente zu den entsprechenden Kupplungselementen der Schutzanzugseinheit korrespondieren und eine mechanische Kupplung der beiden Einheiten ermöglichen, und zwar ohne Unterbrechung der jeweils möglichst weitgehend fluiddichten Trennung der jeweiligen Innenräume vom Außenraum, so dass die Atemschutzeinheit durch die Person beim Tragen der Schutzanzugseinheit bequem mitgetragen werden kann, insbesondere in der Art eines Rucksackes wie oben beschrieben.

According to a third aspect, there is provided a respiratory protection unit comprising:

• - respiratory protective equipment for the treatment of respiratory air,
• A second barrier by means of which an inner space of the respiratory protection unit can be separated by itself, ie not by arrangement within the protective suit unit cover, as far as possible from the outer space, but also from the interior of the protective suit unit, with the aid of a respiratory protection unit cover,
• At least one respiratory protection unit outside coupling element, preferably several, which are arranged on the outside of the respiratory protection unit envelope,
• - Wherein the breathing protection unit side coupling elements correspond to the corresponding coupling elements of the protective suit unit and allow a mechanical coupling of the two units, without interruption of each largely fluid-tight separation of the respective interior spaces from the outside, so that the respiratory protection unit comfortably carried by the person wearing the protective suit unit can be, in particular in the manner of a backpack as described above.

Incidentally, in advantageous embodiments of both the protective suit unit and the respiratory protection unit, the corresponding features may be included, which are both disclosed above with respect to the protective suit arrangement and the protective suit units and respiratory protective units executed there.

Further advantages and advantageous refinements and developments of the protective suit arrangement, the protective suit unit and the respiratory protection unit will become apparent from the following, illustrated in connection with schematic figures embodiments.

Show it:

1 a cross-sectional view of a protective suit assembly with a protective suit unit and a respiratory protection unit and a breathing tube and respirator,

2 a protective suit unit in cross-sectional representation,

3 a respiratory protection unit with a breathing air hose and respiratory protective equipment with SCBA and PAPR, including respiratory protection filters,

4 a respiratory protection unit according to 3 in a reduced representation, without SCBA and PAPR with respiratory filters in cross-section,

5 a schematic cross-sectional view of the two inside and outside clutch plates of the protective suit unit.

The same, similar and equivalent elements are provided in the figures with the same reference numerals. In some figures, individual reference numerals may be omitted for clarity. The figures and the proportions of the elements shown in the figures with each other are not to be considered to scale. Rather, individual elements may be exaggerated in size for better representability and / or better intelligibility.

1 shows a schematic cross-sectional view of a protective suit arrangement 1 comprising a protective suit unit 2 , which can be designed as a chemical protective suit CSA. This has an interior 22 on, passing through the protective suit cover 23 from an outdoor space 3 is separated, in which harmful agents, such as an atomic, chemical or biological hazard, such as harmful gases or biochemical suspended matter or even atomically, chemically or biologically contaminated precipitate may be present. The separation of the interior 22 from the outside space 3 done by a protective suit 23 , This is for example made in one piece and has a header 21 , an arm area 25 , a hand area 26 , a leg area 27 and a foot area 28 on, leaving a person 7 the suit 2 can easily wear close to the body. The individual regions can, however, also each be designed in one piece, with each other by gas-tight connections, such as plastic welded joints or the like, be interconnected. It is crucial that the protective suit unit envelope 23 as a media-breaking barrier 21 is formed, which is the first interior 22 the protective suit unit 2 from the outside space 3 if possible with source of danger so separated from each other that possibly in the outside space 3 Existing dangerous agents can not penetrate through the protective suit cover and so the health of the person wearing it 7 is also protected in the danger area.

To the head area 29 is a respirator 24 molded or attached via a breathing air supply hose 5 is fluidly connected to a breathing air supply.

The breathing air supply takes place via a respiratory protection unit 4 , which has a quick coupling that can be easily connected 45 with the breathing air supply hose and above with the respirator 24 connected is. The quick coupling 45 can be easily, preferably by a helper, separate from the respiratory protection unit when it is to be replaced, and reconnect with a new respiratory protection unit, in the example of a new, freshly filled breathing bottle 46 is arranged, which the carrier person 7 supplied with breathing air, so that they can continue to operate in the danger zone.

Preferably, the breathing air hose 5 Protected against contamination by a hose made of special protective material, which protects the breathing tube 5 from the connection to the respirator 24 up to the quick coupling 45 surrounds.

In cohesive connection with the inner surface of the protective suit cover 23 is located in the interior 22 a protective suit unit inside clutch plate 71 , On the opposite side of the protective suit unit cover 23 are also cohesively to the protective suit unit envelope 23 attached protective suit unit exterior clutch plates 72 , About rivets 73 at shoulder height and in the abdominal cavity height, the interior-side and outer-room-side protective suit unit coupling plates are non-positively connected to one another in such a way that the protective suit unit envelope 23 from the two protective suit unit side clutch plates 71 and 72 is trapped. By clamping the extensive gas-tightness of Schutzanzugseinheitshülle 23 maintained. Optionally, in the breakthrough areas for the rivets 73 through the protective suit unit cover 23 On both sides additional sealing rings, such as rubber O-rings concentrically arranged around the rivets, so that the sealing effect is enhanced.

Outside, through the rivets arranged close to the shoulder 73 are on the outside clutch plate of the protective suit unit 2 two upper coupling elements 612 . 622 attached, near the belly, by the local rivets 73 (Perspective only one rivet is visible) are on the outside clutch plate 72 two lower coupling elements 611 . 621 attached.

1 further shows a respiratory protection unit 4 , analogous to the protective suit unit 2 , a respirator unit case 43 includes an interior 42 the respiratory protection unit 4 as media-tight as possible, in particular encloses gas-tight. In the respiratory protection unit 4 is a respiratory protective equipment 44 arranged for treatment and supply of breathing air. The respiratory protection unit cover 43 serves as the second media-breaking barrier 41 the protective suit arrangement 1 that the interior 42 the respiratory protection unit 4 from the potentially dangerous outdoor environment outside 3 separates. In the respiratory protection unit 4 is a respiratory protective equipment 44 arranged here in the form of an SCBA and a PAPR. Also in 1 recognizable are two respiratory protection filters 441 outside to the respiratory protection unit 4 the PAPR can draw in air, which may block dangerous suspended particles and other hazardous substances from the breathing air supply.

The range of breathing air filters 441 is easily accessible from the outside so that they can be easily exchanged. For example, from the outside, a helper can simply unscrew the filters that are consumed and new, unused filters 441 Screw.

Also the respiratory protection unit 4 has a breathing protection inside arranged breath protection unit inside clutch plate 81 on, which directly to the Atemschutzeinheitshülle 43 is arranged cohesively. On the outside of the side of the respiratory protective cover 43 is a corresponding outside space breathing protection unit clutch plate 82 arranged. Analogous to the clamping of the protective suit unit cover by the local clutch plates is also here as possible a gas-tight clamping of the respiratory protection unit envelope 43 between the two clutch plates 81 and 82 in the form of shoulder-side rivets and hip-side rivets, which are the two clutch plates 81 and 82 non-positively connect with each other by clamping the breathing protection unit envelope 43 , Again, if necessary, in order to increase the gas-tightness, O-rings on both sides of the rivets are striped.

Via a breathing apparatus coupling element 444 is the respiratory protective equipment 44 to the breathing protection unit inside clutch plate 81 attached, so also an exchange of respiratory protective equipment 44 can be carried out quickly as soon as the respiratory protection unit is to be replaced or reconditioned after use. Preferably, the respiratory protective coupling element is also 444 over the rivets 73 at the respiratory protection unit inside clutch plate 81 attached.

Also the respiratory protection unit 4 has upper and lower coupling elements 622 and 621 on, with the corresponding upper and lower coupling elements 612 and 611 interlocking L-shaped connectors are mechanically coupled. In this way, the respiratory protection unit 4 so to the protective suit unit 2 be mechanically coupled without, for example, the protective suit unit must be opened. As a result, in the field is a problem-free change a used respirator 44 with a fresh, unused possible, by simply replacing the entire respiratory protection unit 4 , preferably by a helper person. This increases the service life in the hazardous area in which respiratory protective equipment must be used under certain circumstances considerably, which is often crucial in particularly time-consuming operations.

A quick coupling 45 , For example, a gas-tight running hose coupling, the respiratory protection unit 4 attached, leaves a simple and quick coupling of the breathing air hose 5 and so with the associated respirator 24 to.

A switching element 51 on the breathing tube 5 allows switching from PAPR to SCBA as required, as soon as the danger situation makes it possible to have another breathing air supply only via PAPR and to switch over to bottle supply via SCBA. Conversely, of course, a switch back to the PAPR mode is possible as soon as the danger situation has weakened and a PAPR supply via the respiratory protection filter 441 again provides adequate protection in the dangerous situation. Also, you can toggle between SCBA and PAPR as soon as the filters 441 have reached too high a degree of contamination, so that only one SCBA operation is possible.

2 shows a cross-sectional view of the protective suit unit 2 , Inside the protective suit unit 2 is one on the upper body of the person 7 to be fixed carrying frame 74 that with the inner clutch plate 71 the protective suit unit 2 connected is. On the support frame are two shoulder straps 75 of which in the cross-sectional view only a shoulder straps 75 is shown arranged. The shoulder wearer 75 , as well as the shoulder straps, not shown 75 for the wearer's other shoulder 7 , is also on the inner clutch plate 71 the protective suit unit 2 attached, which is why both the Schutzanzugseinheitseitig clutch plates 71 and 72 as well as via the upper and lower coupling elements ( 612 . 622 . 621 . 611 ) coupled respiratory protection unit 4 can be worn in the style of a backpack.

3 shows a respiratory protection unit 4 according to the protective suit arrangement 1 and a breathing tube 5 with switching element 51 For example, an electronic control switch 51 , which controls the valves accordingly, so that you can switch between SCBA and PAPR operation. The breathing air bottle 46 , which is part of the SCBA, is with the respirator 442 connected.

4 shows a respiratory protection unit 4 without respiratory protective equipment 44 and without filter elements 441 , The respiratory protection unit 4 is as a backpack 4 educated. It is manufactured in at least two versions. A first embodiment is for receiving the PAPR, the second execution for SCBA and PAPR. If the operation is only required with SCBA, this would require a third backpack execution, not shown here. The coupling plate 81 inside the backpack 4 serves in each case the attachment of the used respiratory protective equipment 44 For example, SCBA, PAPR and Breathing Air Bottle 46 ,

A PAPR or the combination of PAPR and SCBA is or are fixedly connected to the plate by a fastening element, not shown here, alternatively only one SCBA is connected to the plate. The backpack 4 is designed so that the necessary for the operation of the PAPR filter 441 from the outside gas-tight to the respirator blower 442 can be connected. There are breakthroughs for this 443 provided by the outside through the Atemschutzeinheitshülle 43 the filters 441 can be mounted. In a pure SCBA operation on the backpack no breakthroughs 443 be provided for the filter.

For ergonomic reasons, first the protective suit unit 2 and the carrying device 74 . 75 and then before closing the protective suit unit 2 the SCBA with breathing bottle 46 and the PAPR with Respiratory protection fan 442 as well as the protective mask. This ensures that the carrying device 74 . 75 with the added weight of respiratory protective equipment 44 (SCBA and / or PAPR) can be optimally adjusted to the body again. Again, this should preferably be done with the help of a second person.

The protective suit arrangement 1 is thus formed in two parts and can thus as a hybrid respiratory protection system 1 be designated.

Thus the hybrid respiratory protection system 1 at any time remains free of contamination, this is before use in its own gas-tight backpack 4 stowed away from special protective material. It will be together with the backpack 4 (Respiratory protection unit 4 ) to the protective suit unit 2 attached. So every variant of protective suit arrangements 1 whether with PAPR or with SCBA or both, can be worn safely, there is a backpack for each variant 4 ,

The invention is not limited by the description based on the embodiments of these. Rather, the invention includes every new feature and every combination of features, which in particular includes any combination of features in the embodiments and claims.
