Waterproof cold protection clothing

For fishing and other work in cold seas, for example in northern waters during the cold season, is to protect workers from the cold and save the lives of workers who have fallen into the sea waterproof cold protection clothing is desirable.

To create a well-known, waterproof, cold protective clothing parts corresponding to a jacket, pants, gloves and boots are assembled and become one of the protective suit obtained in this way was worn separately or connected to the hood. All parts of this protective clothing are waterproof and heat-insulating, and at least the jacket part generates so great buoyancy that the wearer of the protective clothing on the water level floats. Furthermore, the jacket part is provided with a waterproof fastener at the front and the jacket part can can be put on and put down with the lock open. The hood has an opening at the front, the edge of which is made of flexible material exists so that no water can enter the interior of the protective clothing through this opening. Such protective clothing however, diminishes the wearer's ability to move and work and in a position he or she desires to swim on the surface of the water.

O OU / OO

In particular, the waterproof cold protection clothing is designed so that its wearer when properly put on Protective clothing cannot drown or die within a short period of time if dropped into water. However, if a Person who has properly put on the waterproof protective clothing described above, in the event of an accident or if something like this falls into the sea, this person swims in an almost horizontal position. If she is unconscious and her front turned downwards, the face is immersed in the water, so that the wearer of the protective clothing suffocates. But even if If the wearer is not unconscious, he will swim on the surface of the water in a position that makes it difficult to rescue, and indeed in one almost horizontal position with the head tilted downwards due to the greater weight.

When fishing at sea, the worker often sweats heavily, even in the cold season and independently whether he wears the familiar waterproof cold protection clothing or not. This sweating is great on the physical Effort attributed to the work involved is. For this reason, waterproof cold protective clothing is usually used with the upper part of the fastener open when working worn so that the protective clothing rests loosely on the wearer's neck. If the wearer is one in this state When wearing protective clothing falls into the sea, the cold sea water kicks in through the open upper part of the fastener into the protective clothing, so that it no longer fulfills its task can.

The worker often wears waterproof cold protection clothing with the fastener open at work, because the parts of the neck and wrists around the

Protective clothing is waterproof. When properly laid out

waterproof cold protective clothing, the parts of the protective clothing surrounding the neck and wrists lie against the aforementioned Body parts of the wearer of the protective clothing fed up and these parts of the protective clothing are expediently elastic or through Bandages gathered. Because the part of the protective

Ifc. 3ung that constricts the neck often becomes a relief often the shutter is open.

The invention has the object of eliminating the disadvantages of the known waterproof cold protection clothing explained above to eliminate.

In particular, the invention is intended to be a waterproof Use clothing that protects against the cold and that normally does not constrict the neck too much when worn while working but which can be quickly created a watertight seal on the neck if this is necessary. e.g. if the wearer of the Protective clothing has fallen into the sea.

The invention also has the object of creating waterproof cold protection clothing in which the buoyancy her jacket part centered on the neck part can be enlarged so that her wearer, if he is with the front facing downwards floats on the surface of the water, is reliably turned over to a position in which its front is turned upwards is.

The trousers part C is provided with outside pockets 5. On the front of the jacket part B, in the vicinity of shoulder parts, ventilation hoses or pipes are attached, the inside with not shown Check valves are provided and serve to introduce air into the space enclosed by the outer skin 1. At the Outer skin 1 are also attached to the waist distributed guide elements 7, on which a rescue rope is fixed, with the a hook ring is connected to one end.

The buoyancy of the material of the outer skin 1 is not sufficient to carry a person on the water level. at properly put on protective clothing, however, no water can penetrate into the space enclosed by the outer skin 1, see above that the air between the outer skin 1 and the clothing worn inside the outer skin causes thermal insulation and creates a lift. As a result, the wearer of the cold protection clothing wears one not shown inside the outer skin Inner suit, which mainly consists of thermal insulation material, e.g. a soft foam. The hood A of this Waterproof cold protection clothing has an opening 2a and a neck part 2b.

When the outer skin 1 of the above-described, known waterproof cold protective clothing over the inner suit is worn and its closure closed properly

is, it cannot easily happen that on the collar and the wrist band water enters the space enclosed by the outer skin 1. · because the neck band and the wrist band fit snugly against the wearer of the protective clothing. Furthermore, the effect between the outer skin 1 and the inner suit or the air trapped in the undergarment of the wearer provides thermal insulation and creates this. Air a lift. When the wearer of properly put on protective clothing into the sea falls, it can therefore not easily happen that a large amount of water enters the space enclosed by the outer skin 1, so that the waterproof cold protection clothing does its job. In doing so, however, the wearer of the protective clothing swims on the surface of the water in a dangerous, essentially horizontal position. If the wearer of the protective clothing is at im If the area of the collar with the open closure 4 falls into the sea, the waterproof cold protective clothing can no longer do its job perfectly meet.

In Figures 3 and 4 is an embodiment of the waterproof cold protection clothing according to the invention shown. These are parts that are identical to those shown in FIG match, provided with the same reference numerals.

In Figures 3 and 4, 11 is an inflatable Denotes air chamber, which is formed by a soft film which is connected to the inside of the outer skin 1. In the present embodiment, the inflatable air chamber 11 is over the entire collar and predominantly over the right side part of the front of the jacket part is provided, over the shoulder and part of the chest. The air chamber 11 has parts 11a and 11b, which in the upper Part of the closure 4 provided on the outer skin 1 of its side, which interlocks in the closed state

share protrude. When the upper part of the shutter 4 is open, the overlapping parts 11a and 11a close 11b of the air chamber 11 the space between the side parts of the Closure 4 in the upper part of the same. The part 11c of the inflatable air tube lying over the right part of the chest -ai .. ^ r 11 is big enough. At 12 is a compressed air source, for example a compressed air bomb, from which compressed air can be introduced into the inflatable air chamber 11. For supplying compressed air into the inflatable air chamber 11 the compressed air source 12 can be operated manually or automatically. When the parts 11a to 11c of the inflatable air chamber 11 are separated from each other, a separate compressed air source must be provided for each of these parts. Furthermore, one can provide that the wearer of the waterproof cold protective clothing can blow inhaled air into the inflatable air chamber 11.

Usually, the inflatable air chamber 11 is not filled with air so that it is not a hindrance when putting on protective clothing. The inflatable, but not inflated Air chamber 11 is not a hindrance even if the protective clothing is only loosely applied and the closure 4 is only partially closed is.

If now the wearer of the loose protective clothing, i.e. with the fastener 4 only partially closed has fallen into the sea while working, the wearer can by opening the compressed air bomb 12 compressed air into the inflatable air chamber 11 initiate. As a result, the inflated parts 11a and 11b of the inflatable air chamber 11 overlap each other, so that the previously open part of the shutter 4 is now closed. Furthermore, the inflation of the air chamber 11, that the inner wall around the neck fits snugly against it. In this way an entry of water into the from

the space surrounding the outer skin 1 is essentially completely avoided. If you close the shutter 4 completely, the waterproof system of the collar 2 is further improved, so that no water can enter the collar 2.

In this embodiment, to enhance the effect of the invention, the hood A with an inflatable Air chamber 21 may be provided.

According to FIG. 4, the hood A provided separately from the outer skin 1 can cover the head and the outside of the collar 2 of the outer skin 1. The hood A has an opening 2a through which the eyes, the nose and the mouth exposed. The inflatable air chamber 21 consists of a part 21a which extends over the entire collar 2b of the hood A and a part 21b which extends over the rear part of the hood and is provided with a compressed air bomb 22 which is connected to the inflatable air chamber 21.

When the wearer of the protective clothing, with the hood A on, enters part 21a of the inflatable air chamber with compressed air initiates from the compressed air bomb 22, the inflated part 21 a of the air chamber 21 presses from the outside against the collar 2 of the Outer skin, so that the collar 2 allows water to enter the collar 2 into the space enclosed by the outer skin 1 prevented. When the part 21b of the inflatable air chamber provided on the rear part of the hood A is inflated this part 21b, together with the part 21a of the inflatable air chamber surrounding the collar, acts on the head Buoyancy, which is very desirable because in this way the head of the wearer of the cold protection clothing who has fallen into the water is reliably held up. This effect can be supported by the fact that in the hood A on the inside

side of the edge of the opening 2a an inwardly inflatable Provides air chamber 21c.

An inflatable air chamber 11 or 21 can therefore be provided on the jacket part B and / or on the χ - »Duze A.

By one on the inside of the outer skin 11 part 11c provided over the right part of the rib cage the inflatable air chamber 11 can achieve the following effect:

If the wearer of the waterproof cold protective clothing is facing downwards on the water level W floats, as shown in Figure 5 at (1), seeks most of the air that is in that of the outer skin 1 enclosed space is to pass over the carrier M and to form an air layer 1a. Hence there is the air that is enclosed in the space which is not sealed by the outer skin 1 is, almost completely above the water level W, while the carrier M surrounded by the outer skin 1 is the Protective clothing is located below the water level 1. So far it has often happened that the wearer M is the known waterproof cold protective clothing in this position could not turn around, so that he drowned, well the wearer of the known protective clothing floated on the water level W in a substantially horizontal position. This was due to that in the pants part C and the boot part D of the outer skin 1 was a considerable amount of air and the above-described air layer formed over the carrier M. Therefore, it was extreme for the wearer M of the protective clothing difficult to turn around on the water surface.

If, on the other hand, the wearer M of the protective clothing according to FIGS. 3 and 4 falls into the water and initially swims on the water in the position shown in FIG. 5 at (1), he quickly moves into the position shown in FIG. 5 at (2) because the portion 11c of the inflatable air chamber 11 overlying the right part of the wearer's chest can be inflated inwardly from the outer skin 1 so that the outer skin 1 becomes the same; The blown air chamber part 11c is drawn towards and the volume of the air layer 1a located on the rear side of the carrier M according to FIG. 5 is reduced. At the same time, through the inflated part 11c of the inflatable air chamber 11 provided on the front side of the carrier M and by a layer of air 1b surrounding the part 11c, a lift is generated which causes a torque to be exerted on the carrier M, which the carrier M in Rotates clockwise into the position shown in FIG. 5 at (3). When the carrier M is rotated, the buoyancy generated by the inflated part 11c of the air chamber 11 and by the air layer 1b surrounding the part 11c increases progressively, so that the carrier M is finally completely turned around and the position shown in FIG. 5 at (4) occupies.

It is understood that thanks to the inflatable air chamber 11 located on the right or left part of the front of the jacket part of the outer skin is provided, the floating wearer of the waterproof cold protective clothing is reliably rotated from a position in which its front is facing downwards to a position in which its Front is turned upwards, and that thanks to this inflatable air chamber also first with the outside in Connected part of the interior of the protective clothing is sealed watertight.

A compressed air bomb 32 is provided for introducing compressed air into the inflatable air chamber 31. When the parts 31a to 31c of the inflatable air chamber 31 are independent of each other a separate compressed air bomb is provided for each of these parts. The compressed air bomb 32 can if necessary from Hand or automatically to deliver air to the inflatable Air chamber 31 are actuated. Instead of the compressed air bomb 32, another device for delivering compressed air can also be used into the inflatable air chamber 31 provided in the interior of the outer skin 1. For example, a device can be provided with which the wearer of the protective clothing can blow inhaled air into the inflatable air chamber 31.

Normally, the inflatable air chamber 31 is not filled with air, so that it is when the protective clothing is put on is not a hindrance. The inflatable but not inflated air chamber 11 is not a hindrance even if the protective clothing only loosely applied and the shutter 4 is only partially closed.

If the wearer of the waterproof protective clothing according to Figures 6 and 7 only loosely put on the protective clothing has, i.e. the fastener 4 is only partially closed, or if he has not put the hood A on his head, and he If the protective clothing falls into the sea in this state, the wearer of the protective clothing can open the compressed air bomb 32
