Buoyancy and rescue equipment for divers.

The invention relates to a combined buoyancy and rescue device for divers, so that they can regulate their buoyancy underwater and, in an emergency, are kept in a position on the water surface that prevents them from fainting, comprising a buoyancy jacket with an inner bladder, overpressure protection and carrying straps, as well as a diving bottle.

Diving jackets are used by divers to control their buoyancy underwater and also to swim easily on the water surface. Diving jackets are therefore buoyancy and buoyancy aids, but not rescue devices, as it cannot be guaranteed that a diver will be turned into a safe supine position and held there. A so-called fainting-safe supine position can only be reliably achieved by expensive diving life jackets, which, however, do not provide sufficient help when lying on your back on the water surface when swimming over long distances or when resting.

The invention addresses the problem of producing a buoyancy and rescue device of the type mentioned above from relatively simple elements, whereby one element, the buoyancy jacket, can be worn like a diving jacket, but in an emergency a position safe from fainting of the diver on the water surface can be ensured.

This is achieved by the fact that the combined buoyancy and rescue device of the type mentioned above has an inflatable diver rescue collar, which is attached to the collar area of the

Buoyancy compensating jackets are fastened by means of zippers, straps, snap fasteners, laces or similar, and are connected to the lower carrying strap of the buoyancy compensating jacket in the chest area by at least one strap.

The diving rescue collar can either be attached to the buoyancy compensator or carried in one of the pockets of the buoyancy compensator. All known connecting devices can be used, especially zippers, so that the upper part of the diving jacket can be connected to the diving rescue collar in the simplest way possible.

It is particularly important, however, that the diver's rescue collar is designed with at least one strap in the front area, which in turn reaches to the lower strap of the buoyancy jacket and is connected to it there. In this way, the inflated diver's rescue collar can exert such a force or torque on the diver that he is inevitably brought into the supine position, which prevents him from fainting.

According to the invention, the diver's rescue collar can be inflated in three different ways, whereby all three means can be implemented on a diver's rescue collar at the same time:

A mouth inflation device can be provided, a CC^ bottle or a 0.5 liter compressed air bottle can be present and finally there can be a direct connection to the diving bottle or the jacket, in which case an overflow device with a non-return valve is provided.

The invention is further characterized in that the carrying straps are designed as endless loops that run out of the legs of a "Y" in the rear part of the jacket and lead over the diver's shoulder and under his arm around his side to the base of the "Y" and that the trunk (14) of the "Y" is designed as a starting point for the straps for securing the diving bottle. With the help of such a design, it is possible to achieve a high level of wearing comfort, since the weight of the bottle is carried in the lower part of the diving jacket and in the immediate vicinity of the body.

The invention is explained below by way of example with reference to the drawing.

Fig. 1 shows a front view of a jacket.

Fig. 2 shows a side view of the jacket.

Fig. 3 shows a schematic rear view, while

Fig. 4 shows a schematic representation of the bottle holder on a jacket.

Fig. 5 shows a side view of a complete buoyancy and rescue device according to the invention.

In the figures, the right belt is marked 11 and the left belt 12. The belts have standard buckles and adjustment devices. However, the belts 11 and 12 are connected together by diverging parts 13 to a belt part 14 running downwards, with the other belt parts running forwards leading to the

lower area of the belt part 14. This can be seen in particular in Figure 3, in which a diver is shown in outline in order to express the actual conditions more clearly.

15 denotes pockets in the front area of the jacket, as well as a belt 16 that can be closed in front of the wearer’s body.

The inner bladder is protected against bursting by three pressure relief valves 30, two of which are located in the upper shoulder area and one in the lower side area.

A bottle 20 can be attached to the back of the jacket via a strap 21, with an additional strap 22 being provided which is attached to the neck of the bottle.

Figure 5 shows a side view of a buoyancy compensator jacket, whereby only one strap 11 can be seen due to the side view. This strap 11 is connected at 50 via a zipper to a rescue collar 51 that is essentially U-shaped. The rescue collar 51 has two straps 52 in its two front end sections, which lead to the lower carrying strap 11 and are connected to it there in a suitable manner. Belt fasteners and the like can be used for this purpose.

At 53 a CO2 unit is shown, 54 is an overflow device with a check valve between the rescue collar 51 and the oxygen bottle 40, while 55 represents the pull cord for the CG^ bottle.
