[0051] FIG. 14 a, b show the operating handle from FIG. 13 comprising a mouthpiece arrangement.

[0052] FIG. 1 shows a schematic illustration of a functional unit 1 of an avalanche rescue system. The functional unit 1 comprises a first functional element which comprises a buoyant element 2, a gas cartridge 3, and a gas line 4 connecting the gas cartridge 3 to the buoyant element 2. The gas line 4 leads into a connection piece 5. The gas cartridge 3 is connected to the gas line 4 via a pressure control valve 6. In addition, a securing pin 7 is provided, which is connected to a triggering system which will be described in greater detail.

[0053] The buoyant element 2 comprises connection tabs 8, by means of which the buoyant element can be connected to a functional element carrier which will be described. In the illustration shown, the buoyant element 2 is folded and compressed.

[0054] A second functional element comprises a balloon 9 and a gas cartridge 10 which is connected to the balloon 9 via a valve 11 and a gas line 12. The valve 11 likewise comprises a securing pin 13 which is connected to a triggering system.

[0055] The gas in the cartridge 10 is preferably lighter than air. The pressure of the outflowing gas is controlled by the valve 11. A check valve is located on the underside of the balloon 9. This valve prevents a reverse flow of the gas and ensures that all of the gas contained in the cartridge 10 is dispensed into the tear-proof balloon 9. The balloon 9 is connected to an elastic cord which is marked with colors and is not shown here. The elastic cord has been wound onto a pulley which is connected to a functional element carrier which will be described further below. This pulley is characterized in that it allows for a lengthening as well as a shortening of the cord. A danger posed to the user by the cord is thereby prevented. The cord has a color scale which subdivides the cord into three regions without indicating the metric distance to the buried person. This means that, in order to exactly determine the position of the buried person, a pinpointing of the location must be carried out using an avalanche probe, and risky misinterpretations of the distance must be avoided, which can occur if a metric scale is used. The use of an elastic material for the cord prevents a possible injury in the neck region of the buried person. Given that the balloon is filled with a gas that is lighter than air, an independence from the principle of inverse segregation is made possible and, as a result, the localization of a buried person is improved.

[0056] A further functional element which is provided is a ventilation functional unit which comprises a gas cartridge 14 containing liquid oxygen. The gas cartridge 14 is connected to a tube 17 via a valve 15 and a vaporizer 16 which also functions as a pressure regulator. In addition, a securing pin 18, which is likewise connected to a triggering system, is provided on the vaporizer 16.

[0057] The tube 17 is routed through an adjustable-length protective sleeve 19 to an operating handle 20. The protective sleeve 19 is designed in the form of a bellows in order to enable the length to be adjusted. The protective sleeve 19 is fixed at a fixing point 21. The tube 17 or the protective sleeve 19 is routed in an insulation casing 23 along a carrier belt 22 designed as a shoulder belt. The insulation casing can be formed from Neoprene, for example. The tube 17 is routed within the protective casing 19 in parallel to sections of the operating handle 20. The tube then leads into a hollow part 25 of the operating handle 20, on the end of which a mouthpiece 26 is provided. The mouthpiece 26 is made of a flexible material in order to protect the oral cavity of a user. The flexible material cannot be compressed to the extent that gas no longer flows through. Openings 27 are provided below the mouthpiece 26, through which expired respiratory air, in particular CO.sub.2, can flow out.

[0058] The operating handle 20 is fastened to a carrier system, in particular to the carrier belt 22, via a locking joint 30. By means of the locking joint 30, the position of the operating handle 20 can be adjusted, in particular pivoted. The locking joint 30 comprises grooves on the back side thereof, which interact with corresponding pipings 31, 32 in order to fasten the locking joint 30 and, therefore, the handle 20, thereon. The height of the operating handle 20 can also be adjusted along the pipings 31, 32.

[0059] When a triggering is carried out, one part 25 of the operating handle 20 is triggered or torn off, and therefore the operating handle 20 can be guided to the mouth of the user, and the user can receive the mouthpiece 26 in the mouth. The protective casing 19 can expand in this case. The length of the tube 17 is sized in such a way that a guidance to the mouth of the user is easily possible. Alternatively or additionally, the tube 17 can also be designed to be length-adjustable.

[0060] The operating handle 20 can be fastened on a locking plate 33 which is designed as a breastplate. The locking plate 33 can be fastened on a chest belt 34.

[0061] A triggering system 40 is provided for triggering the functional elements, which, in the exemplary embodiment shown, comprises a control cable or a Bowden cable (see Hg. 5 for details) which branches at the top into strands 41, 42, 43 which extend to the securing pins 7, 13, 18. If the operating handle 20 is pulled, the securing pins 7, 13, 18 are therefore pulled out, and therefore gas can flow out of the corresponding cartridges 3, 10, 14.

[0062] The functional elements are therefore simultaneously triggered. If a person becomes buried, not only is a visual position-finding function made possible, but the supply of respiratory air to the buried person is ensured. In this context, the short time window between the triggering of a snow slab and the instant in which the winter sports enthusiast is caught by the avalanche requires that the operating handle 20 be guided to the mouth of the buried person as quickly as possible. A triggering of the functional elements is automatically implemented when this guidance is carried out. If a functional element were to malfunction, two further functional elements are still available, which increases the chances of survival for a buried person.

[0063] FIG. 2 shows a functional element carrier 50 which can be designed as a foam plate. The functional element carrier 50 has recesses 51, 52, 53 in which components of the functional elements are disposed. In this case, the buoyant element 2 is fixedly connected to the functional element carrier 50 via connection tabs 8. The functional element carrier 50 has through-passages 54, through which, for example, parts of the triggering system can be routed. The functional element carrier 50 can be detachably connected via a fastening means 55 to a carrier system, for example, a backpack. Gripping tabs 56 can be provided on the upper end in order to facilitate the removal of the functional element carrier 50. FIG. 3 shows a cross section of a further plane of the functional element carrier 50. In this case it is apparent that further recesses 57, 58, 59 are provided, in which an avalanche rescue shovel 60, an avalanche rescue probe 61, and the cartridge 10 and the balloon 9 are disposed.

[0064] FIG. 4 shows a carrier system 70 which is designed as a backpack in which the functional element carrier 50 is disposed. It is apparent that an opening 71 for the buoyant element 2 is provided on the carrier system 70. This opening 71 can be closed, for example, by means of a velcro closure which automatically opens when the buoyant element 2 is filled with gas. In addition, a through-passage 72 for the protective casing 18, including the tube 17 and the triggering system, is apparent. In principle, it is also conceivable to route the tube 17, including the protective casing 18, out of the carrier system 70 through a lower through-passage 73. Previously described elements are labeled using the previously used reference numbers.

[0065] FIG. 5 shows a detailed illustration of the operating handle 20. In particular, it is apparent that the hollow part 25 of the operating handle 20 can be separated from the adjustable-length part 80. Given that the part 25 is removable, an erroneous triggering of the functional elements can be prevented. It can be necessary, for example, when traveling in a gondola, to remove the operating handle 20 in such a way that an erroneous triggering can be avoided. A sliding element 81 can therefore be provided on the handle 25, by means of which an interlocking with the plug-in part 82 can be triggered. On the other hand, the handle 25 can be easily installed on the plug-in part 82 in order to connect the two handles 25, 80 to one another. In the region of the sliding element 81, the handles 25, 80 can be separated/torn apart during a triggering.

[0066] The tube 17, including the protective casing 19, can also be detachable from the handle 25 at the point 83, but it must not detach during a triggering of the functional elements, of course. The handle 25 can be provided with increased static friction 84 on its surface and, for example, can be rubberized. The handle can also be provided with recesses 85 which facilitate a reliable grip.

[0067] It is also apparent that the tube 17 is designed in the shape of a “Z”. It is therefore length-adjustable. It is therefore ensured that the tube 17 can be lengthened so far that a reliable guidance of the mouthpiece 26 to the mouth of a user is possible. The protective casing 19 is also length-adjustable.

[0068] The locking joint 30 has grooves 87 on both sides (front side and back side). As a result, the locking joint can also be mounted on the other side of a carrier system. The grooves 87 can be covered by a faceplate 88.

[0069] It is also apparent that the triggering system 40 comprises a control cable 89 and a casing 90. The triggering system 40 therefore comprises a Bowden cable.

[0070] FIG. 6 shows a cross section of the part 80 of the operating handle 20. It is apparent here that the triggering system 40 has been routed into the locking joint 30 and connected to a telescopic part 80.1. The telescopic part 80.1 is routed inside the telescopic part 80.2. In the position shown, the telescopic part 80.1 is fixed in the telescopic part 80.2 by means of the pushbutton 91 which extends through an opening in the telescopic part 80.2. The length of the part 80 is changed by pressing the pushbutton 91 and displacing the telescopic part 80.1 relative to the telescopic part 80.2 until the pushbutton is locked in the opening 80.3. The state in which the length has been changed is therefore fixed.

[0071] The triggering of the functional elements takes place against the restoring force of a spring element 92 which bears, at one end, against the telescopic part 80.1 and, at the other end, against an extension 93 of the locking joint 30. The restoring force is advantageously greater, in this case, than the force required for (forcefully) tearing the handle 25 off of the handle 80.

[0072] If the part 80 is pulled to the left, the situation shown in FIG. 7 results. The spring element 92 was compressed and the catch 94 engages behind the extension 93 of the locking joint 30. The catch 94 is deflected by a small spring element 95, and therefore an automatic interconnection takes place when the part 80 of the operating handle 20 is pulled to the left. This interlocking is noticeable by a user, and therefore haptic feedback is provided. In this situation, the functional elements are triggered (the cord 89 has been pulled to the left). The triggered position is locked in place by the catch 94. The catch 94 can be released again by means of a sharp object.

[0073] It is also apparent that the locking joint 30 comprises a ball 96 which can be moved into a cup 97. Recesses 98, 99 in the fixed part 100 of the locking joint 30 allow for a pivot movement without adversely affecting the function of the operating handle 20. Instead of a ball 96, a disk could be simply provided, although only limited pivotability could then be implemented.

[0074] FIG. 8 shows the region in which the operating handle 20 can be displaced with respect to the horizontal plane of the body. As a result, a user can select the optimal angle. In particular, a pulling angle of the operating handle 20 can be set in the range of 0°-30° with respect to the horizontal plane of the body. The adjustable pulling angle supports the ergonomics of the triggering and can prevent an erroneous gripping of the operating handle 20.

[0075] As shown in the illustration in FIG. 9, the operating handle 20 can be locked in the retracted state on the locking plate 33 by a locking means 101, such as, for example, a velcro fastener.

[0076] As shown in FIG. 10, a locking in the extended state of a breast plate 33 is also possible by means of a further locking means 102.

[0077] While the use of the operating handle 20 on the left side—as viewed from the user—was depicted in the previous illustrations, FIG. 11 shows that the operating handle 20 can also be installed on the right side. In particular, the locking plate 33 can be used on the right or left for this purpose. The locking joint 30 can also be fastened on two opposite sides and is designed accordingly. The operating handle 20 according to the invention and the functional unit can therefore be used by right-handed persons as well as left-handed persons.

[0078] FIG. 12 shows a user who has triggered the functional elements. In particular, it is apparent that the buoyant element 2 has been inflated and is wider than the user. The neck of the user is enclosed by wings 110, and therefore the neck region is protected. In this case, it is apparent that the buoyant element 2 comprises a Venturi tube 111, by means of which it is ensured that the buoyant element 2 will fully inflate. The user has torn the operating handle 20 out of the anchoring on the telescopic part 80 and has inserted the mouthpiece 26 into the mouth. The balloon 9 has been inflated and the cord 112 has been at least partially unwound. In the exemplary embodiment shown, the carrier system comprises not only a hip belt 113 but also leg belts 114.

[0079] FIG. 13 shows one alternative embodiment of a handle 200. The handle 200 is designed substantially in the shape of a “T”, wherein the legs 201, 202 are angled with respect to a base leg 203. In particular, the leg 202 has an angle, with respect to the base leg 203, of less than 90°, and the leg 201 has an angle, with respect to the base leg 203, of more than 90°. An air channel 204 is formed in the leg 202, by means of which the ventilation function can be implemented. The handle 200 is therefore designed hollow in sections. A mouthpiece, which will be described in greater detail, can be connected to the leg 202. It is also apparent that two control cables 205, 206 designed as Bowden cables are disposed on the handle 200. Both control cables 205, 206 or only one thereof can be connected to the handle 200, as necessary. In particular, the control cables 205, 206 are detachably connected to the handle 200. One of the control cables 205, 206 can also be used, for example, for actuating an electronic actuating mechanism for a functional element. It is likewise conceivable to use an activating cable for an electronic triggering mechanism, instead of one of the control cables 205, 206.

[0080] FIG. 14a shows a mouthpiece arrangement 210 having a mouthpiece 211 and a connection piece 213 which is disposed on the operating handle 200. The mouthpiece 211 is connected via the flexible connection piece 213 to the operating handle 200, in particular to the leg 202. If an emergency situation occurs and a ventilation function must be implemented, the mouthpiece 211—as shown in FIG. 14b—can be moved with respect to the leg 202, in particular can be pulled out slightly. This is possible since the flexible connection piece 213 is utilized. In the present case, the flexible connection piece 213 is designed as a bellows-type tube. The mouthpiece 211 can now be moved and displaced in any way with respect to the leg 202, and therefore the mouthpiece can be moved toward the mouth of a user in an optimal manner.
