    At least parts of the protective G-trousers are double-walled and thus airtight compartments (13, 18, 34, 35) are formed on the inside or outside, to which compressed air can be applied. These G-protective trousers are made entirely of a breathable, tear-resistant, fire-resistant and low-stretch synthetic textile fabric of a maximum of 130 grams / m 2, and the G-protective trousers are only equipped with compartments (13, 18, 34, 35) that are called pneumatic Muscles work and can pull adjacent pieces of textile together by inflating them. The compartments (34) on the outside of the trouser legs extend at the top towards the lower abdomen into a bag-like bladder (13) each and are connected to the compartments (35) for the insides of the trouser legs via a groin channel (18). The compartments (34) communicate on the back of the pants via a connecting channel. From this point on, a coccyx canal extends downward between the buttocks and cheeks of the wearer in the cross area.

    description
    The present invention relates to an acceleration protective pants or briefly called G-protective pants, instead of a conventional whole G-suit for the crew of high-performance aircraft.
    When turning, high acceleration forces can occur. For the pilot's organism, with positive g-forces along the vertical axis, this means that the blood from the upper regions of the body sags downwards. The heart has to perform better for a sufficient blood and thus oxygen supply to the brain and eyes. However, if its - individually different - capacity limits are exceeded, the lack of oxygen can lead to impaired vision (Tunnelblic, Greyout,) or even to complete unconsciousness (blackout) (g-induced loss of consciousness - G-LOC) and thus mission abort and / or accidents. High g-forces occur, for example, in flight races, in aerobatics and in military flight profiles (aerial combat, interception maneuvers after the use of weapons, etc.). To a certain extent, aircraft crews can suppress or delay the negative effects of high g-loads. In addition to appropriate training, you can achieve this, for example, through targeted muscle tension or pressure breathing. These measures are supported by technical solutions such as inclined seats, press ventilation with oxygen-enriched air and antig suits or a combination of these options. Ultimately, however, limitations in performance and ability to act and rapid exhaustion cannot be completely prevented.
    G protective suits are known in various designs. A distinction is made between those that are exposed to air as a pressure fluid, i.e. so-called pneumatic G protective suits and those that work according to the hydrostatic principle and either allow the hydrostatic pressure to act directly on the person wearing the protective suit, or those suits that have fluid veins are provided, which run essentially in the local and instantaneous Z-axis and increase the internal pressure corresponding to the liquid column by shortening the circumference of the protective suit around the limbs of the body. These are both simply called hydrostatic G protective suits, although the liquid is by no means limited to water. Known G protective suits emerge from EP 1 755 948, which is probably the closest prior art, and also from US 2007/0289050, JP 2008 012 958 and DE 10 2007 053 236. Furthermore, a G protective suit is from WO2012 / 066114A1 known.
    In such G protective suits, the body regions to be protected and / or body parts are usually surrounded by the G protective suit or parts thereof. The body parts and regions, which are particularly stressed by the often extreme accelerations, are put under pressure within such G protective suits by means of bubbles or hoses charged with compressed air or gas depending on the accelerations in the current and local Z-axis, called Gz, resulting in the hemostatic pressure of the pilot is counteracted. This is the general task of such G protective suits.
    The effort for a sufficient G-protection is still considerable with conventional suits and it is a thrust of this invention to reduce this effort especially in that a sufficient G-protection alone is achieved with a G-protective pants instead of a complete suit. These protective G-trousers are designed to provide sufficient G-protection for applications that make up about a third of the entire relevant market, taking into account the entire market, i.e. not just the market for solutions for high-performance combat aircraft alone, but also those for less demanding applications, for example for use in jet trainers and generally in aircraft, in which similar accelerations occur. These acceleration or G-protective pants should be effective under all circumstances and in all conditions without any special behavior on the part of the pilot, as are necessary with conventional G-suits, especially in the border area.
    Conventional G protective suits are relatively heavy and stiff, and the wearer easily sweats in them, which negatively affects their natural G tolerance and well-being. Some G-suits can cause foot and arm pain in the wearer, and there are general medical doubts about the positive pressure breathing (PPB) they induce. G protective trousers should therefore ensure absolutely reliable G protection, i.e. the prevention of so-called G locks, and ensure this G protection with as little effort as possible, if possible without making breathing under overpressure necessary. The G-protective trousers should develop their optimal effect in all situations and offer the highest possible wearing comfort, almost as comfortably as underwear, without any influence on the part of the wearer, i.e. without "Anti G Straining Maneuvers" (AGSM) by the wearer or pilot They should prevent the pilot from getting tired early and reliably prevent pain. In addition, these protective G trousers should also provide buoyancy support when immersed in water. Optionally, the G protective trousers should include an active cooling device. These G protective trousers should be manufactured as standard trousers The tailoring of such G-protective trousers for individual wearers, as was previously mostly necessary for suits, should no longer be necessary.
    Since the contact pressure has so far been generated by the shell of a G protective suit on the body of the wearer, depending on the body part to be protected, the bubbles that cause these contact pressures are of different sizes. As can be seen from the prior art documents, the volumes of the bubbles are relatively large, up to almost full coverage of the lower body, which in combination with the compressibility of air and taking into account the high onset rates of Gz leads to a slowed response of the G protective suits leads.
    The object of the present invention is mindful of the facts set out above to create an acceleration protective pants or G-protective pants, by means of which the internal pressure according to the relative height of the body to be protected and according to the acting local and instantaneous acceleration Gz is controllable and furthermore the volumes to be filled for this purpose remain small. The G-protective trousers should also be comfortable to wear without requiring a precise fit. They should be easy to put on and take off, comparable to putting on ordinary jeans trousers, and avoid the excessive pressure breathing that is otherwise necessary in a G-suit. In addition, it should offer additional functions such as air conditioning in optional versions. Another task of these G-protective trousers is to facilitate the venous return of the blood in the pilot's legs by changing the rhythm of the internal pressure generated. These protective G trousers should also not change the position of the hand of the pilot on the thigh when inflating under G loads, since no pressure bubbles are positioned on the thigh. Eurofighters, F / A-18s and other aircraft have a central control stick, and pilots often place their control arm on their thighs to provide long-term support or to facilitate regular flight in a long turn. Ultimately, these G-protective trousers should also be able to be worn over an aviator suit, and even be specially equipped for this purpose over the aviator boots, so that they can be put on effortlessly, easily and quickly and taken off again when the aviator suit and the aviator boots are already on.
    The solution to the problem is realized by an acceleration protective pants or G-protective pants for pilots of aircraft in which high accelerations occur, with at least parts of the G-protective pants are double-walled and thus airtight compartments on the inside or outside are formed, which can be acted upon by acceleration-dependent air pressures, characterized in that the G-protective trousers consist entirely of an air-permeable, tear-resistant, fire-resistant and stretchable synthetic textile of a maximum of 130 grams / m2, and the G-protective trousers are only equipped with such compartments which are either lined with an airtight rubber material on the inside or an elastically stretchable air hose runs through them, so that the compartments can be converted into an approximately circular cross-section by pumping them up and thus their two opposite edges can be pulled together and the adjacent pieces of fabric stretched , wherein compartments run continuously along the inside and outside of the trouser legs and are connected at the upper end of the trouser legs via a groin channel running along the lower area of the lasts, and the compartments on the outsides of the trouser legs extend further upwards from the lasts and towards the lower abdomen into a bag-like bladder each, while they communicate with each other via a connecting channel on the back of the pants, in the area of the cross of the wearer, and a coccyx channel branches off from the connecting channel in the cross area and branches down between the buttocks of the carrier extends in the direction of the crotch, and wherein the interior of the compartments is in communication with a compressed air supply via at least one hose with raccord.
    In the dependent claims, particularly advantageous designs of these G-protective pants are claimed in a more precise form.
    With the aid of the drawings, these protective G-trousers and the underlying inventive concept will be explained in more detail. It shows:

    In order to better understand the essence of the invention, the systems of protective G-trousers according to the prior art are first briefly presented and discussed. For this purpose, FIG. 1 shows what is known as a 5-bladder G protective trousers in the pulled-on state. It is worn over a pilot's overall 23 and several bladders - five in number - are integrated into it. There are recesses in the area around the crotch and in the front area of the knees to ensure freedom of movement for sitting. The bubbles are all connected to one another and are inflated via a compressed air hose if necessary. All of these recesses cause blood congestion at their edges, similar to the doctor's blood pressure cuff, which can lead to circulatory disorders, increased blood pressure and increased heart rate.
    Figure 2 shows this the bladder system of these G-protective pants with their five communicating bladders 26 separately. The bladders 26 are supplied with compressed air via a hose 27. Inside the G protective trousers
    one bladder 26 each covers the thigh on its front side and the lower leg on its front side as well. In addition, a fifth bladder 26 acts on the lower abdomen. When this bladder system is pressurized, the bladders 26 are inflated according to their geometry and generate tension on the wearer's body with the aim of counteracting the hemostatic pressure of the pilot. The large volumes of the bubbles 26, which firstly make the system relatively sluggish, with correspondingly long reaction times, have a disadvantageous effect. Second, these airtight bladders 26 cover relatively large parts of the wearer's body and prevent sweat from being carried away there. Therefore, such G-protective pants proves to be a real "headlock", that is, they create a build-up of heat in the legs and wear comfort is accordingly reduced. In contrast to the new G protective pants according to this application, this type of G-pants must be shown in FIG be worn very tightly in order to achieve a discreet performance, which greatly restricts free movement and wearing comfort.
    Figure 3 shows another example from the prior art, namely a full coverage G-Schutzhose.Bei these pants, which are shown here loosely lying on a plane, the bubbles extend over much larger parts of the body of the carrier, as will be shown below. These conventional G-protective trousers are made from a relatively heavy and non-breathable textile material according to ISO 9237 20 to 90 l / m2 xs, preferably from a fireproof Nomex aramid fabric as the outer shell, in which the bladder is located. The bladder system is made of polyurethane-coated nylon. The outer shell is equipped with zippers for the waist and legs, for example with six adjustable lacing areas with laces and two easily removable leg pockets with zippers. Pockets 28 with viewing windows 29 are incorporated on the front of the thighs for receiving documents. Again: In contrast to the new G-protective trousers according to this application, this type of G-trousers shown in FIG. 3 must be worn very tightly in order to achieve a discreet performance, which greatly restricts free movement and comfort.
    Figure 4 shows the bladder system of this full coverage G-protective pants shown separately. The bladder 30 extends practically around the entire surface of the legs by looping around the two legs from the outside except for a gap 31. At the top, the bladder 30 is continued over the lumbar and lower abdominal area 32 and covers these up to the lateral hips. This bladder 30 is supplied with compressed air from a hose 33 which opens at the side. Here, too, the covering of large parts of the legs and the lower abdomen proves to be disadvantageous for the dissipation of heat from the body. Many parts of the body are covered by these pants with airtight material and they therefore act as real "sweat pants", because when you are flying you sit on the body and therefore no heat can be dissipated from the pilot's body. These are correspondingly uncomfortable to wear Full coverage G protective trousers. The large volume of the one-piece bladder 30 leads to a system-related inertia, i.e. the reaction times for pressure build-up and pressure build-up again are relatively long.
    The G-protective pants according to the invention as shown in Figure 5, in contrast to the previously known G-protective pants, basically and consistently consist of a unique material specially developed for this purpose, which has a high air permeability according to DIN EN ISO 9237 of over 500 l / m2 xs min offers. This material is also characterized by an extremely high tensile strength according to ISO 13934-1 of up to 2000 N / 5 cm. ISO 13934-1 specifies a method for determining the maximum force and elongation of fabrics using a strip method. The method is mainly applicable to textile fabrics, including fabrics that have elongation properties imparted by the presence of an elastomeric fiber, mechanical or chemical treatment. It can be applied to fabrics made using other techniques. As a rule, it does not apply to geotextiles, nonwovens, coated fabrics, glass fabrics and fabrics made from carbon fibers or polyolefin tape yarns. The method specifies the determination of the maximum force and elongation at maximum force of test specimens in equilibrium with the standard atmosphere for the test and of test specimens in the wet state. The procedure is limited to the use of CRE testing machines (Constant Rate of Extension).
    This G protective suit as shown in Figure 5 offers an extremely high load capacity with a very low stretch and its weight per unit area is only 121 +/- 5 grams / square meter. This material is worn directly on the skin, which also eliminates the compressibility of classic underwear. For reasons of hygiene, however, the G-protective trousers can optionally be worn with specially adapted, fire-resistant, wafer-thin and air-permeable textile underwear. These G-protective trousers are exceptionally comfortable to wear, a feeling on the skin like a very fine natural cotton. However, this fabric consists of fireproof, fully synthetic, antistatic, very hard-wearing and low-stretch yarn mixtures, including Armamid fibers, which are processed into a breathable fabric.
    As a special feature, this G-protective pants is not built on the basis of a conventional bladder system, but it includes a pneumatic muscle system of compartments with a small and divided belly bladder 13. Outer compartments 34 extend along the outside of the two trouser legs from the waistband to lower hem of the trousers. Inner compartments 35 extend along the insides of the pant legs from the crotch down to the lower hem of the pants. These outer 34 and inner 35 compartments are connected to one another along the lower strip edge 11 via a respective strip channel 18. At the front and back between the outer 34 and inner compartments 35, single-layer, air-permeable textile strips 14, 15 (FIG. 13) rest directly on the front and rear sides of the legs. The outer compartments 34 extend above the legs over the lower abdominal area and each form a sack-like pocket for the formation of a bubble 13 each, so that the two bubbles 13 thus formed cover the entire lower abdominal area. On the back are the two
    outer compartments 34 connected via a channel, as will be clear from further drawings. The entire lower body, including the legs, is pressurized if necessary, despite a small area coverage by these compartments 34, 35, 18, 13. The pneumatic muscles pull the bubble-free pieces of fabric 14, 15 together immediately when necessary and encircle the body parts covered with them or limbs. These G-protective trousers manage with an extremely light overall weight, which corresponds to about a third less weight than that of conventional G-protective trousers.
    The built-in compartments 34, 35, 18, 13 act as pneumatic muscles for contracting. These compartments are integrated into the textile material, for example by sewing or gluing or welding, by doubling up by applying a strip of textile material inside or outside of the general textile material of the G-protective trousers, so that the strip is only connected to the textile material at its edge. These compartments are made of the same low-stretch material as the rest of the textile material. In a first embodiment, flexible, stretchable hoses made of an elastomer are inserted into these compartments, which expand when pressure is applied. These inflated hoses then lay against the inside of the compartments and, to a certain extent, inflate them to a circular cross-section. As a result, the two lateral edges of the compartments move towards each other, that is, they contract, and thus tension the textile pieces adjoining the outside of the compartments. In another embodiment, the compartments are lined on the inside with a rubber-elastic, air-impermeable material. When air is pumped into the interior of the compartments, the compartments instantly expand to a circular cross-section and contract the outside pieces of textile, which then encircle the covered parts of the body and thus exert pressure on them.
    Figure 6 shows the geometry of the subjects or the pneumatic muscles of the G-protective pants according to Figure 5, which can be inflated with compressed air and are integrated into the G-protective pants, in the state when spread out on a plane. The compartments 34 are intended for the outside of the two trouser legs. The compartments 35 drawn on the outside in the picture, on the other hand, are intended for the two insides of the trouser legs and they are turned over for installation as indicated in FIG. 7 with the curved arrows. At the top, the compartments 34 for the outside of the legs are each connected to the compartments 35 for the inside of the legs via a groin channel 18. The compartments 34 for the outer sides of the legs extend even further upwards from the crotch to the waistband. They each run out into a sack-like pocket as a bladder 13, which two bladders 13 then jointly cover the entire lower abdominal area. The outer compartments 34 are connected to one another via a further channel 17 with the area coming to the rear, in the cross area 16 of the carrier. From this channel 17 branches off in a downward direction a coccyx channel 5 which then extends downward between the buttocks of the wearer.
    In Figure 8, this fan geometry is shown in a spatial representation, on a G-protective trousers with the inside facing outwards, with the compartments 35 for the inner sides of the pant legs, based on the situation as shown in Figure 6 and Figure 7 , turned inside. The compartments 34 for the outer sides of the trouser legs thus run on the outside along the outer sides of the trouser legs and are connected to the inner compartments 35 in a communicating manner via the last channels 18. The areas between the outer 34 and inner compartments 35, however, remain free of an airtight covering or are bridged by a well air-permeable textile material. In the lower abdomen area, starting from the position in FIG. 6 and FIG. 7, the sack-like pockets folded inwards can be seen as bubbles 13. In the cross area, the connecting channel 17 and the coccyx channel 5 branching off from it downward can be seen.
    All such pneumatic muscles for the legs are incorporated only on the outside and inside of the two trouser legs, so that the front 14 and back 15 of the trouser legs remain free of compartments and the fabrics lie there in a single layer directly on the legs and in them Areas a high air permeability is offered in order to allow sweat to diffuse to the outside. Inflation on the upper side of the thighs when sitting is thus effectively avoided. The pilot can rest his forearm on his thigh regardless of the G-load and the pressure exertion on the G-protective trousers, and the arm remains calm when the load changes. This particularly facilitates continuous turning.
    In Figure 9, a cross section through such a textile compartment is shown as a pneumatically acting muscle. On one side, which can be arranged on the outside as well as on the inside of the basic trouser material 4, a textile strip 7 is applied. On the inside of the compartment formed in this way, however, this is completely lined with a rubber-elastic, airtight layer 2. In the two corners 6 of the compartment 1, the airtight coatings 2 are brought together in a sealing manner. If air is pumped into the interior of this compartment 1, it puffs up because the air cannot escape and finally the compartment assumes a circular cross-section. It is clear that the textile pieces 14, 15 adjoining the two sides of the compartment - here on the left and right of the compartment - are drawn together as a result, as indicated by the arrows. In Figure 10, the compartment 1 shown is partially inflated. This inflation can be continued until the cross section of the compartment 1 becomes approximately circular, as shown in FIG. Dry Air Cooling System Option: The air then passes through the lip-shaped openings 19 onto the body surface of the wearer, where it has a cooling effect for him.
    Instead of equipping the compartments 1 with an airtight rubber-elastic coating on the inside, an expandable rubber-elastic tube can also be passed through the interior of a compartment 1. When air is pumped into the same, it expands and finally fills the interior of the compartment 1 completely, and with sufficient internal pressure
    this hose is able to inflate the compartment to an approximately circular cross-section. The subsequent textile pieces 14, 15 are drawn together accordingly.
    Figure 12 shows these G-protective trousers with the inside turned outwards in the limp state lying on the floor, seen from the front, with the two trouser legs slightly bent in the knee area spiced outwards. As on the outside of the pant legs, compartments 35 also extend on their inside from step 10 down to the trouser hems 9. From step 10, groin channels 18 extend obliquely outwards and upwards, along the lower edge 11 of the groin to the outside Page 12 of the pants. From there, further compartments each in the form of a sack-like pocket as a bladder 13 extend horizontally along the waistband 8 to the middle of the belly of the wearer.
    Figure 13 shows the G-protective pants with the inside turned outwards in the state with little inflated compartments seen from behind. As this FIG. 13 shows, the waistband 8 can be equipped with belt loops 3. The compartments 34 for tensioning the trousers in these G-protective trousers presented here run from the vicinity of the waistband 8 of the trousers down on the two outer sides of the trousers, along the outside of the trouser legs down to the trouser hems 9 both sides of the trousers, the compartments 34 extend horizontally to the cross area 16 and in particular cover the outer halves 25 of the buttocks. From the middle of the back of the waistband, a compartment in the form of a coccyx channel 5, 2 to 6 cm wide, extends downwards by at least 20 cm, to the height of the crotch of the wearer of the trousers. If air pressure is applied to the pneumatically interconnected compartments, they all bulge out and all contract in width. They therefore shorten the distances between the two fan edges and thus tension the adjoining textile parts 15 and thus enclose the covered body parts with more or less tensile stress. Because the textile for these pants is a very low-stretch textile material, both in terms of fiber stretch and binding stretch, this tensile stress and tight enclosure of the body parts, in particular the thigh and lower leg, but also the entire pelvic area and in particular the buttocks, is very effective and instantaneous implemented. At the same time, this textile material is particularly breathable and therefore air-permeable. It is precisely this property that ensures that the wearer can perspire and that his sweat can escape through the flat pieces of textile lying on the body. The textile sections 15 between the outer 34 and inner compartments 35 on the back of the trouser legs are made of thin and air-permeable fabric and are used for comfortable sitting. They ensure the most natural possible contact with the seat of the cockpit seat. The wearing comfort is therefore very significantly and incomparably improved compared to conventional air-impermeable or almost air-impermeable fabrics. When empty or flat, the compartments are a few centimeters wide.
    Figure 14 shows these G-protective trousers with the inside turned outwards in the limp state with a view of the right side, lying on the floor, the left trouser leg being shown slightly moved forward. The inner compartment 35 can be seen here on the left trouser leg and the outer compartment 34 on the right trouser leg. The textile pieces 14, 15 lying between the compartments 34, 35 of a trouser leg are made of thin and air-permeable material. Those on the front of the legs are designated here with 14, those on the back of the legs with 15. There, these areas 14, 15 above all ensure that, firstly, the tension built up by the compartments 34, 35 is maintained because the fabric is elastic , and secondly - very important - that the sweat, when the wearer perspires, can diffuse to the outside thanks to the good air permeability and thus breathability of the textile material. Because these protective G trousers are also made of particularly light textile material, they offer a level of comfort previously unknown for G suits. On the front of the G protective trousers you can see the right of the two sack-like pockets, which act as bubbles13 and which are in front of the Extend the wearer's abdominal area.
    In Figure 15, these G-protective pants are shown with the inside turned outward in the tensioned state with inflated compartments seen from the front. Here, the compartments 34 running along the outer sides of the trouser legs are inflated, as are the compartments 35 running along the inner sides of the trouser legs. The inner compartments 35 open at the top into welt channels 18 which run along the lower edges of the groin, i.e. obliquely outwards and upwards and inwards guide the side areas close to the waistband 8. From the side areas in the hip area, a sack-like pocket branches off on each side of the G protective trousers to form a bladder 13 towards the middle of the abdomen. In this figure, the textile strips 14 can be seen on the front of the trouser legs, they are made of thin and air-permeable fabric, so that the low-stretch but very breathable fabric lies directly on the wearer's bare leg. The wearer can transpire over these front and rear sides of the trouser legs, i.e. his sweat can efficiently diffuse outward through the textile strips 14, 15, which greatly increases the wearing comfort of these protective G-trousers.
    Figure 16 shows the G-protective pants with the inside turned outwards in the slack state with empty compartments 13, 18, 25, 34, 35, seen from the left side. In this representation one looks at the outer compartments 34 on the left outer side of the left trouser leg. In the knee area, the compartment 34 is cut in such a way that an indentation 20 is formed which enables the knee to be angled for the sitting position in the cockpit seat without tension. Otherwise, the compartment 34 is continuous, for the thigh as well as the lower leg of the wearer.
    Figure 17 shows the G-protective pants with the inside turned outward in the partially stretched state with not fully inflated compartments 13, 18, 34, seen from the right side, with differently developed knee areas of the two trouser legs. Here one can clearly see the clearly visible compartment 34 on the right side of the trousers, that is to say the right trouser leg and the right hip. One recognizes the sack-like bladder 13 in front of the lumbar region
    extends along the same below the waistband 8 and which collides with the symmetrical, opposite bladder 13 in the middle.
    In Figure 18 these G-protective pants are shown with the inside turned outward in the flaccid state, put on a virtual body, seen from a slightly oblique front, to show the position of the individual components inside. One recognizes the outer compartments 34, along the outer sides of the trouser legs, and the inner compartments 35 along the inner sides of the trouser legs. In between, thin and air-permeable pieces of textile 14 are arranged to maintain the tensile stress when the compartments 34, 35 are inflated, and to allow perspiration to diffuse out. At the top, the inguinal ducts 18 adjoin the inner compartments 35, and then, above them, the two sack-like bladders 13 for pressurizing the groin area in the inflated state. The G protective trousers come to an end with the waistband8. Only two additional zippers 36 (FIG. 18) are led from the crotch to the waistband in order to enlarge the waist somewhat in the event of a great increase in weight of the wearer. These G-protective trousers are designed and sewn with a similar fit to the trousers of a leather motorcycle suit, i.e. with trouser legs for bent legs. Ultimately, this results in a much more comfortable sitting position when exposed to high pressure.
    FIG. 19 shows this embodiment of the G protective trousers with the inside turned outwards in the flaccid state, put on a virtual body, viewed from the left, to show the position of the inner components. You can see the outer compartment 34 on the outside of the left pant leg, the thin and air-permeable piece of textile 14 attached to the front and the thin and air-permeable piece of textile 15 attached to the back. The compressed air supply is already available in aircraft that are flown with G protective suits. It allows a finely adjustable, automatically controllable supply and discharge of compressed air.
    In Figure 20 shows the G-protective pants with the inside turned outwards in the flaccid state, put on a virtual body, seen from behind, to show the position of the inner components. Here you can see the thin and air-permeable textile inlays 15 on the back of the trouser legs and the two compartment areas 25 which cover the outer halves of the wearer's buttocks. The same is also shown in FIG. 21 in a view obliquely from the rear. Underneath the waistband 8, the two buttocks compartments 25 can be seen underneath, following the outer compartments 34, which approximately cover the outer halves of the buttocks of the wearer.
    The airtight inner fan coatings or the air hoses inserted therein consist of an elastomer, that is to say they are flexible and stretchable. As shown in FIGS. 9 to 11, they are enveloped on both sides by less stretchable textile coverings and form the compartments 1 of the G protective trousers. If the air hoses or the interior of the fan coatings 2 in the compartments 1 are acted upon with compressed air, then they stretch adjacent textile pieces and thus build up a circulating tension o, which over the relationship
    o = p ■ r builds up a pressure p inside the body tissue. So is
    . g [N / m] I p lA! 1
    p inversely proportional to the local curvature r of the body part.
    It is one of the special tasks of these protective G trousers not to have to provide a tailor-made piece of clothing for every pilot, but rather to get along with a single protective G trousers within a size class of wearers. Pressurizing the compartments also serves this purpose.
    The main valve for the compressed air supply is also a safety valve. This immediately closes the compartments from the outside world as soon as
    - the cabin pressure collapses for any reason, or
    - the pressure supply from the aircraft fails.
    At such a moment, the protective G-trousers act like a pressure suit and keep the pressure conditions stable within uncritical limits. Conventional, approved aviator suits (overalls) can be worn over these G protective trousers according to the invention, possibly with additional functions for protection against NBC influences and / or cold water. The G protective trousers can also be equipped with a dry air cooling system for even more comfort extremely hot climate conditions.
    Thanks to the exclusive, very little stretchable fabric, but at the same time very breathable and air-permeable, the amount of air required to build up pressure with these G-protective trousers could be greatly reduced and accordingly the pressure build-up and pressure reduction are faster. For the first time, these G-protective trousers are as easy to put on as ordinary jeans. Although no tight adaptation to a specific body constitution is necessary, these G-protection trousers can offer effective G-protection for clothes up to two sizes higher. No lacing is required to achieve a tight fit on the body. Despite the fact that no laces, straps or buckles have to be operated for individual adjustment, no pressure reduction has to be accepted and no loss of time when building up pressure due to otherwise stretching laces and straps for size adaptation.
    These G-protective trousers are also able to apply pressure to the buttocks without an air cushion effect that is accepted there, thanks to the tension around the buttocks area generated by the pneumatic muscles. The G-protection is thus considerably increased compared to the usual full printing of G-trousers, that is, full-surface printing with bubbles, but without printing on the bottom. What is also unique is the fact that these G-protective trousers can be worn tucked into the boots with the trouser bumps, as shown in FIG. 19 and FIG. This can effectively prevent foot pain under G-load. A check valve between the compartments (5, 13, 17, 18, 25, 34, 35) and the outside of the protective G-trousers can be installed, which closes the pressure in the event of a sudden loss of pressure in the aircraft and / or in the cockpit atmosphere maintains the subjects. Another built-in valve can be activated by immersion in water by means of a moisture sensor so that the compartments then retain their air content and generate buoyancy accordingly.
    A particularly interesting embodiment of these protective G-trousers is shown in FIGS. 22 to 24. In addition, such G protective trousers are shown in FIG. Figure 22 shows the lower part of the pant legs which encompass the lower legs of the wearer. These can be opened by means of a zipper 37 that can be opened from the lower edge of the trouser leg up to the crotch. Depending on the design, these zippers 37 can run on the front of the trouser legs, as shown in the picture. In another variant, the zippers 37 can run along the inside or outside of the trouser legs, up to the crotch. In FIG. 22, these G protective trousers are shown with the right lower leg of the trousers open. This wide opening allows the wearer to get into his trousers with his already on aviator suit and with his already put on aviator boots and at the end just have to close the zippers 37 running along the inside or front of the trouser legs Getting in your pants and getting out of your pants is therefore possible in a few seconds in a way that has never been possible, not even remotely before, with a G protective suit. Until now, a G protective suit was always difficult to put on and never quickly put on, and certainly not over the aviator suit and the aviator boots.
    FIG. 23 shows these G protective trousers with closed zippers 37 along the two lower legs. The trouser legs lie snugly against the legs and the G-protective trousers are always ready to go into action. Due to their tight but comfortable cut, their fit and their very air-permeable fabric, in contrast to all other very voluminous G-pants and their non-air-permeable fabrics, a pilot can leave these G-pants completely on even during longer breaks or interruptions on the ground, or In addition, he can still open the zippers 37, which further increases the wearing comfort of the G-protective trousers. It is then hardly noticed by the wearer.
    In Figure 24, a pilot is shown who wears these G-protective pants, namely over his aviator suit and over his pilot's boots, so that the trouser legs of the G-protective pants end like those of a robbery pants on the shoes of the boots. The zippers 37 run here on the front of the pant legs, from the bottom up into the groin area, where they run under the insert pockets 28, which for this purpose can be folded away to one side and held in the position shown here by means of Velcro fasteners. A model is also provided without fixed pockets and only with Velcro strips, with which the pilot can adapt the choice of the used bag to the daily mission. With these protective G-trousers, the pilot is always ready to climb into the aircraft cockpit and take off and climb up for an operation.
    Depending on the design of these G-protective pants, these can either be worn under a Fliegerkokmbi, or just as a special feature over the aviator suit and over the pilot's boots, which is particularly convenient for the wearer, because then he can quickly take off these G-protective pants for interruptions and put on again just as quickly if necessary and get ready for an operation within seconds.
    As far as the care of these G-protective trousers is concerned, it should be mentioned that they are very easy to wash and can therefore be easily kept clean. It can be washed in a conventional washing machine. The particularly light fabric, weighing a mere 121 ± 5 grams / square meter, proves to be dirt and stain-resistant and is therefore very easy to wash, even if it is badly soiled with oil or kerosene. The protective G trousers as presented are suitable for military flight operations with both western and eastern aircraft platforms, for every aircraft platform in use. Only the connectors for pressurization have to be changed or adapted depending on the aircraft platform.
