A preferred embodiment of the special suit according to the invention includes a in FIG. 1 shows multilayer fabric 100.

The multi-layer fabric 100 includes an outer protective layer 110, which protects against undesired external influences e.g. against an open one Flame, extreme cold and / or against a toxic environment. The outer gas impermeable Protective layer 110 can in particular be formed from several layers, which isolates against individual external influences, i.e. e.g. from a heat repellent Layer, a liquid-impermeable layer, a cold insulating Layer, a radiation-opaque Layer and / or a ballistic protection, especially against projectiles or splinter ensuring layer.

The multi-layer fabric 100 further comprises an inner layer 120, which in particular on the skin H of the person wearing the special suit rests, the inner layer 120 in particular also textile underwear may include. The inner layer 120 is permeable to moisture, in particular water vapor, to perspiration or sweat of the person in the multi-layered Allow tissue 100 to penetrate from the inside (in one direction W in FIG. 1), wherein the inner layer 120 can preferably be of the type which transports moisture or sweat away from the skin H of the person, cached and to the fluid in the distance layer 130 for air conditioning delivers.

The multi-layer fabric 100 further comprises between the outer one Protective layer 110 and the inner layer 120 a spacer layer or spacing or spacing layer 130. The spacing 130 can be a textile spacer fabric made of natural and / or synthetic fibers comprise which yarns cross-linked or connected to one another in the manner of cells having. The spacer fabric has in particular interconnected, coplanar (in a direction C in FIG. 1) to the spacer layer 130 fluid-permeable channels, which have a coplanar flow in particular the distance layer 130 guaranteed by a fluid. Thus the fluid Moisture, which is released by the body, absorb and after derive outside. The resilience and the spacing or pressure resistance the spacer 130 further ensure that the fluid permeable Channels are not interrupted, even if the distance 130 by the weight of the person wearing the special suit 10 and / or is loaded by external forces. The distance layer 130 can with the inner layer 120 and / or the outer layer 110 glued and / or connected be, in particular by means of a Velcro fastener or connection.

The distance layer 130 can be dependent on the body area on which it is arranged to have different thicknesses. Especially with protective suits for pilots it is advantageous in the back and / or rear pelvic area to provide a spacer layer thickness which is greater than in the rest Body areas, with the spacer 130 in the back and / or rear Pool area preferably between about 5 to about 15 mm, preferably about 6 is up to 13 mm, while the thickness in the remaining areas is about 6 mm is. The transitions between areas with increased spacing thickness too the areas with normal distance layer thickness are preferably continuous, so that the person wearing the special suit 10 has no edges or "steps" can feel.

The in FIG. 2 special suit 10 preferably includes the one shown in FIG. 1 shown multilayer fabric 100. The special suit 10 has an inlet E and an outlet A which is fluidly permeable to the fluid the whole body covering distance layer 130 are connected to Inlet or outlet of a fluid in or out of the spacer layer 130. The fluid, air and / or helium in particular is controlled by an air conditioning device 20 air-conditioned, in particular its temperature, humidity, pressure and / or chemical composition regulated or controlled or adjusted and is inserted through the inlet E into the spacer layer 130. The fluid preferably flows around different areas of the body and becomes discharged through the outlet A from the distance layer 130. In particular can different outlets A and / or different inlets E can be provided, and the spacer layer 130 can be divided into fluidly separate sub-areas be, these different sub-areas against each other by sealing means can be sealed or separated. By providing different, separate fluid sub-areas can be provided by one or more air conditioning units 20 different microclimates are generated, which in particular, allow adaptation to external conditions. In particular it is therefore possible to provide protective suits for use in increased acceleration (e.g. with fighter jet pilots) and / or reduced Acceleration (µg missions e.g. with astronauts) are suitable, because they are allow vasoconstriction by locally increasing or decreasing pressure or to pinch off vessels, which is a drainage of Blood e.g. prevented in the leg areas in the event of increased acceleration.

The fluid supplied to the air conditioning device 20 can be in a receptacle or device 30 may be included and / or removed from the environment become.

In the in FIG. 3 shown special suit 10 is the outlet A again with the Receiving container 30 connected via a processing device 40. The Fluid flowing from the distance layer 130 through the outlet A becomes via lines a preparation device 40, which processes the fluid, in particular by removing moisture, filtering substances or substances and / or particles, addition of further substances, etc.

The in FIG. 3 special suit 10 thus has a separate, independent Circuit that is completely separable from the environment, which in particular greatly reduces the risk of contamination.

Furthermore, the in FIG. 3 shown special suit 10 an additional distance in a head region K. This additional distance position is special between an outer protective layer, in particular a plastic outer shell and the head surface or scalp or the head arranged and allows additional air conditioning of the head area and / or a supply of breathing air or gas. The fluid supplied to the head region K can be in the same air conditioning device 20, which are used for the other areas of the body is used, or through a separate system be processed. The fluid which flows into the head region K flows back to the air conditioning device 20 via a treatment device 40 fed.

The air conditioning device 20, the receptacle 30 and / or the processing device 40 can be inside and / or outside of the special suit 10 are arranged. Furthermore, the distance layer 130 can be completely in itself be closed and only serve the insulation, and without one forced air conditioning must be done. This can be done in particular by provision one self-closing inlet E and one self-closing Outlet A can be achieved, which close when they are of the corresponding Lines are separated so that the distance layer 130 "closed" and being separated from the environment. This is especially for Pilot protective suits advantageous from the air conditioning device 20 separated in particular in emergency situations (e.g. when operating the ejection seat), so that a "passive" isolation or basic isolation by providing an insulating air or fluid layer within the spacer layer is advantageous is made possible. As a result, the special suit 10 offers increased insulation e.g. against cooling down if a pilot lands in the water after an emergency exit. Furthermore, penetration of e.g. Air or water in the distance layer 130 prevented.

Furthermore, the distance layer 130 can be thicker or stronger in special areas be a person wearing the special suit 10 who is in the water is to bring into a stable swimming position, in particular also when it passes out. Due to the greater thickness of the distance layer, e.g. in the chest and shoulder areas, a larger total volume per Area of the distance layer 130 reached in these areas, so that if air or a fluid with a density less than the water density in the spacer layer 130 is filled, these areas experience a stronger boost, and the person thus lead to a stable and safe swimming position.

Accordingly, the special suit or protective suit is particularly suitable for use by divers, firefighters, workers on a drilling platform (especially to protect them on the way to the platform e.g. in one Helicopter), motorcyclists, surfers, police officers or members of a special task force etc., where the special suit the wearer against external Protects impacts and its air conditioning, and in particular basic insulation guaranteed.
