Definitions

  • the invention relates to a support device with an avalanche airbag system which comprises an airbag and a filling device for introducing at least one medium into the airbag.
  • an avalanche airbag system which comprises an airbag and a filling device for introducing at least one medium into the airbag.
  • the airbag which has been brought into a stowed position is received in a container of the carrying device.
  • the container has at least one closure element. After the closure element has been opened, the container can be moved from a closed position into an open position.
  • Such carrying devices in the form of rucksacks which are equipped with the avalanche airbag system, are commercially available.
  • avalanche airbag backpacks in which a container in the form of an airbag pocket tears open when a pressure in the airbag pocket, which is caused by the inflation of the airbag arranged in the airbag pocket, exceeds a certain value. Then a zipper gives way, which usually keeps the airbag pocket closed.
  • the airbag pocket is usually a chamber that is separate from a further storage compartment of the rucksack or a container of this type in which the airbag is stored so as to be protected from damage.
  • the airbag pocket ensures that the airbag does not fall out of the backpack during normal use.
  • the airbag should be packed as tightly as possible so that the airbag does not take up unnecessarily valuable backpack volume. This purpose is also ensured by the airbag pocket or the container in which the airbag, which has been brought into its stowed position, is received. If, however, the avalanche airbag system is triggered, this causes the airbag pocket to open as a result of the airbag being inflated, so that the airbag that is then released can continue to be inflated.
  • compressed gas from a cartridge can be used to fill the airbag of an avalanche airbag system.
  • a venturi device is often used in addition.
  • the gas flowing through the venturi device and coming from the cartridge leads to additional ambient air being sucked in.
  • the airbag is then filled both with the gas from the cartridge and with ambient air.
  • the US 2017/216680 A1 describes an avalanche airbag system in which pretensioned torsion springs, after being triggered, tension a frame on which an airbag is held. The opening of the airbag causes air to flow into the airbag via a one-way valve.
  • the WO 2012/035422 A1 a backpack with an avalanche airbag system, in which the airbag is inflated by operating a blower, the blower drawing energy from an electrical energy source.
  • the inflation of the airbag has the effect that the airbag is transported out of an airbag pocket in the rucksack.
  • a disadvantage of the avalanche airbag system is WO 2012/035422 A1 the fact that a considerable part of the energy that is available for inflating the airbag is already used to open the airbag pocket and to bring the airbag out of the airbag pocket by inflating it. Only when the airbag pocket is opened and the airbag, which is tightly folded in its stowed position, is unfolded, can ambient air (or gas from the cartridge) flow freely or largely unhindered into the airbag.
  • the deployment of the airbag from the airbag pocket does not represent a particular challenge with regard to the pressure to be applied for this, since the pressure is present at the beginning of the deployment process , can be up to 300 bar.
  • this very high pressure of the compressed gas in the cartridge can lead to the airbag pocket tearing open in an uncontrolled manner, especially if the opening mechanism is incorrectly designed or damaged.
  • part of the pressure of the compressed gas is used to deploy the airbag from the airbag pocket. On the one hand, this is inefficient and, on the other hand, valuable time could be saved if the cartridge did not need to provide the pressure required to press open the airbag pocket.
  • a fan designed as a side channel compressor for example.
  • a somewhat higher pressure of up to about 100 mbar can be provided and used to open the airbag pocket and to deploy the airbag from the airbag pocket.
  • the fan can only deliver a lower volume flow than a fan which applies a lower pressure or dynamic pressure.
  • the electric motor of an electrically operated blower namely has a characteristic curve which indicates at which dynamic pressure which volume flow can be conveyed.
  • a high dynamic pressure also means a lower volume flow and vice versa.
  • an electrical energy storage device is usually of comparatively large dimensions and, in some cases, a comparatively large fan is also used, which is designed for compression and can thus provide a high dynamic pressure, and yet promotes a higher volume flow than a smaller fan which can provide the same back pressure.
  • the object of the present invention is therefore to create an improved support device of the type mentioned at the beginning.
  • the carrying device according to the invention which can in particular be designed as a backpack, has an avalanche airbag system which comprises at least one airbag and a filling device for introducing at least one medium into the at least one airbag.
  • the carrying device comprises at least one container in which, when the avalanche airbag system is coupled to the carrying device, the at least one airbag that has been brought into a stowed position is received.
  • the container used to store the airbag has at least one closure element. After opening the at least one Closing element, the container can be moved from a closed position into an open position.
  • the support device comprises at least one spring element which is tensioned when the container is brought into the closed position.
  • the moving of the container from the closed position into the open position can be brought about by means of the at least one spring element.
  • the at least one closure element can be opened by actuating an actuating device by means of which the filling device of the avalanche airbag system can be brought into a triggered state. In the triggered state, the filling device brings the at least one medium into the airbag.
  • the at least one spring element is designed as a leaf spring which is integrated into the container and which is pressed into the container when the airbag is packed and is thereby brought into a curved shape.
  • the at least one spring element is designed to convey the airbag out of a receiving space of the container which is designed to receive the airbag that has been brought into its stowed position. If the at least one spring element not only opens the container or the airbag pocket, but also deploys the airbag, the airbag can be filled particularly quickly and even more easily.
  • an essentially rod-shaped spring element can bring about the deployment of the airbag from the receiving space of the container.
  • the at least one spring element is curved in the tensioned state in such a way that the at least one spring element encloses the receiving space.
  • free ends of the at least one spring element are spaced further apart from one another in its relaxed state than in the tensioned state.
  • the at least one spring element does not need to completely enclose the receiving space, but the spring element can be curved State have a U-shaped or circular arc shape, in which the free ends of the spring element are still spaced from one another even in the tensioned state.
  • the spring element can be brought into the curved, tensioned state by pressing the airbag into the receiving space of the container.
  • the closure element is therefore designed so that it can be opened by actuating the actuating device.
  • the at least one spring element can in turn bring about the movement of the container from the closed position into the open position.
  • the at least one spring element therefore presses the container open.
  • the avalanche airbag system does not need to hold energy to open the container.
  • This is advantageous both when designing the support device for an avalanche airbag system, which comprises a cartridge with compressed gas, and for an avalanche airbag system, which has an electrically operated filling device, and the support device is accordingly improved.
  • At least the opening of the container i.e. moving the container from the closed position to the open position, can be implemented independently of the energy reserves of an electrical energy storage device of the avalanche airbag system with an electrically operated filling device or independently of the pressure provided by the cartridge.
  • the pressure of the cartridge can be significantly lower than is usual with current avalanche airbag systems and can be, for example, only 100 bar. This is advantageous, for example, in that there are restrictions with regard to the transport of gas-filled cartridges in aircraft, in which the pressure of the gas stored in the cartridge plays a role.
  • the support device for an avalanche airbag system is designed with an electrically operated filling device, the provision of the at least one spring element is particularly advantageous. Because then less electrical energy needs to be stored by an electrical energy store of the avalanche airbag system, since the container does not have to be opened by means of the electrically operated fan of the avalanche airbag system.
  • the avalanche airbag system can therefore be designed to be particularly small and particularly light.
  • avalanche airbag systems have to be reliably triggered even at very low temperatures of down to -30 degrees Celsius.
  • the performance of electrical energy stores in the form of, for example, accumulators decreases sharply compared to the performance at higher temperatures.
  • the electrical energy stores of avalanche airbag systems with an electrically operated filling device are usually designed to be correspondingly large.
  • the at least one spring element causes the container to open at the same time as the actuation or due to the actuation of the actuation device.
  • a mechanical energy store in the form of the at least one spring element easily provides the energy that is required to move the container from the closed position into the open position, even at very low temperatures.
  • more energy can be used for filling from the electrical energy store of an avalanche airbag system with an electrical filling device of the airbag. This increases the safety of the avalanche airbag system.
  • the airbag can be filled particularly quickly and reliably. Because by opening the container or the airbag pocket quickly and in particular completely, it can be achieved that the airbag can be filled quickly with a particularly low initial pressure.
  • the at least one spring element can be formed from a spring steel which is pretensioned when the airbag is packed or when the airbag is pushed into the container.
  • a spring element made of a carbon material and / or a spring element made of a fiber-reinforced plastic, in particular a glass fiber-reinforced plastic, for example in the form of a rod or the like can bring the container from the closed position to the open position when the closure element is open.
  • At least one further spring element can also be designed as a helical spring, the tension of which can cause the container to be opened.
  • the bias of the at least one spring element used for mechanical opening is generated when the airbag is packed, that is, when the airbag is introduced into a receiving space of the container.
  • the container can comprise a base body and a cover element, wherein the tensioning of the at least one spring element can be brought about, for example, by closing the cover element. With such a configuration of the container, it can be brought into the open position by means of the at least one spring element in a particularly reliable and functional manner.
  • the base body and / or the cover element are preferably inherently rigid, for example by forming the base body or the Lid element made of a plastic, so that the container is designed in the manner of a hard-shell box.
  • at least one spring element embodied, for example, as a leg spring, for opening the container on the container.
  • two spring elements designed in particular as leg springs can be attached in the manner of hinges in a region of the base body in which the cover element is hinged to the base body. In this way, a support device with a particularly robust and functionally reliable opening device is provided.
  • the at least one spring element can comprise a first bracket and a second bracket which, when the container is brought into the open position, delimit an outlet opening of the container.
  • two interconnected partial areas of the container, on which a respective bracket is arranged can be formed in particular from a flexible material, for example from a film-like plastic material and / or from a textile material. As a result, the container takes up particularly little volume when no airbag is accommodated in the container.
  • an ejection of the airbag from the receiving space of the container can at least be supported by a flexible wall material of the container, which is tensioned when the container is brought into the open position. This is because areas of the bracket which are close to one another in the closed position of the container are moved further away from one another in the open position of the container.
  • This preferably causes tensioning of the wall material designed as a flexible sheet-like structure.
  • the tensioning of the wall material in turn preferably causes the airbag to be ejected from the receiving space of the container.
  • the flat structure can be formed in the manner of at least one textile made of fibers and / or in the manner of at least one film made of a polymer material or plastic material.
  • the at least one spring element comprises the first bracket and the second bracket

  • the actuating device only needs to be actuated first in order to open the at least one closure element.
  • a helical spring can bring about the deployment of the airbag from the receiving space of the container.
  • a plurality of spring elements which are curved in the tensioned state are preferably arranged in the container. Because then, on the one hand, the container can be opened very easily and, on the other hand, the airbag can be deployed from the container in a particularly reliable manner.
  • three, five or even more spring elements in the tensioned, curved state can at least partially enclose the receiving space, which are distributed over the length of the receiving space and, in particular, are evenly spaced from one another.
  • a first of the spring elements curved in the tensioned state is preferably held in the tensioned state by the at least one closure element.
  • at least one further spring element of these spring elements is held in the tensioned state due to the closed position of the container.
  • the first spring element only needs to be unlocked by releasing or opening the closure element.
  • the further spring elements then subsequently or almost simultaneously with the first spring element ensure the completely opening the container. As a result, the container can be moved into the open position particularly quickly and reliably.
  • the support device preferably has at least two further spring elements which are curved in the tensioned state. This enables the container to be opened very evenly and at the same time quickly. This applies in particular when the at least two further spring elements are spaced essentially the same distance from the first spring element. However, it is also possible, for example, to provide four or more further spring elements, in which case this is preferred respective pairs of spring elements are spaced equidistant from the first spring element.
  • the at least one closure element preferably comprises a hook which can be moved from an engagement position into a release position by actuating the actuating device.
  • the closure element can be released or opened particularly reliably by actuating the actuating device.
  • the hook coupled to the actuating device can be pulled into the release position by actuating the actuating device, so that the at least one spring element is then unlocked.

  • the at least one closure element can comprise a magnet.
  • a magnet which is displaced parallel and / or perpendicular to the force holding the magnet in its closed position can be moved particularly easily from the locking position into the release position in which the closing element is open.

  • the airbag is preferably arranged in the container, the at least one spring element being connected to a wall material of the airbag.
  • the at least one spring element can be sewn into the wall material of the airbag or sewn onto the wall material.
  • a material strip can be materially connected to the wall material of the airbag, in particular welded, and form a pocket into which the spring element is inserted.
  • the at least one spring element can support the deployment of the airbag or give the airbag a certain structure when the spring element is brought into its relaxed state. As a result, the filling of the airbag with the at least one medium is facilitated.
  • a closure means is preferably secured by means of the closure element, which closure means closes an outlet opening of the container in the closed position.
  • a closure means is preferably designed as a tear-open zipper (burst zip), which can be opened very easily as soon as a holding force is released at at least one tear point of the zipper.
  • tear-open zipper does not tear open in an undefined manner, but only from the at least one tear point.
  • the closure means can be designed as a Velcro fastener or the like.
  • Such a closure means in particular when a plurality of spring elements is provided, ensures that at least one of these spring elements is held in the tensioned state by the closure means closing the outlet opening of the container in the closed position of the container.

  • corresponding fastening means can be provided in the container, for example in the form of clips, Velcro fasteners, hooks with rotatable buckles which are passed through eyelets and the like. This makes it possible to equip the carrying device, which is designed in particular as a backpack, with the avalanche airbag system as required.
  • the carrying device can also be used without the avalanche airbag system, with additional storage space then being available through the container.
  • the mechanical opening and preferably also the deployment of the airbag of the avalanche airbag system from the container is particularly advantageous. Because the opening of the airbag pocket or the container and preferably also the deployment of the airbag from the receiving space of the container is independent of the electrical energy supply of the electric motor, the at least one electrical energy storage device can be made particularly small. This is because no electrical energy then needs to be made available to open the container or deploy the airbag. Rather, the energy is applied by the at least one spring element.
  • the fan can then be designed in such a way that it provides a large volume flow and does not need to apply a very high dynamic pressure.
  • the filling time required to fill the airbag can be kept particularly short.
  • the at least one electrical energy store only needs to provide electrical energy for the electric motor over a shorter period of time.
  • This also contributes to the fact that an electrical energy store with a comparatively low nominal capacity is sufficient to supply the electric motor of the blower with electrical energy.
  • the fan is therefore preferably designed as an axial compressor, since such a fan is designed for a high volume flow.
  • the airbag can be filled within approximately three seconds of the filling process in such a way that it contains a certain volume, for example a volume of approximately 150 liters, of ambient air.
  • the pressure in the airbag which has been inflated to its maximum volume, can then be increased by activating the blower for about three more seconds.
  • the fan can also be designed, for example, as a radial compressor. After the airbag has been inflated or filled, the volume or the pressure in the airbag can be maintained by closing at least one valve.
  • the fan which can in particular be arranged outside the container, remains in the carrying device or in the backpack and is not ejected like the airbag. This also goes hand in hand with the fact that the energy required for extraction can be saved.
  • the actuating device preferably comprises a handle, wherein the electric motor can be started by pulling on the handle.
  • the handle By pulling the handle, on the one hand the filling device is brought into the triggered state in which the filling device introduces ambient air into the airbag.
  • pulling on the handle also has the effect that the at least one closure element is opened and thus the at least one spring element moves the container from the closed position into the open position.

However, as in Fig. 5 shown by way of example, the first leaf spring 56 and four further leaf springs 58 may be provided.
  • Fig. 6 Out Fig. 6 and from Fig. 7 it can be seen that the free ends 60, 62 of the respective leaf springs 56, 58 can be connected to the parts of the closure element 34 that can be detached from one another via straps 70 or similar elements.
  • the airbag 14 In Fig. 6 the airbag 14 is shown in its folded stowed position, in which the airbag 14 is received in the receiving space 50.
  • the stretching of the leaf springs 56, 58 advantageously ensures that the airbag 14 is deployed or conveyed out of the receiving space 50.
  • the then exposed airbag 14 can be filled with ambient air particularly easily and quickly by means of the fan 20.
  • the process of triggering the airbag 14 can thus be broken down into three sub-steps. First, a break point is opened or the closure element 34 is unlocked, then the airbag 14 is ejected from the receiving space 50 by transferring the spring elements in the form of the leaf springs 56, 58 into the stretched, relaxed state. Then the The airbag 14 is deployed or inflated with the help of the electrically operated fan 20.
  • the system is therefore designed in such a way that the airbag 14 is safely transported out of the container 18 or the airbag pocket as a result of being triggered, so that it can simply be filled with air immediately afterwards .
  • Fig. 8 it can be clearly seen how the airbag 14 is deployed or conveyed out of the receiving space 50 and can thus be inflated easily and quickly by means of the blower 20.
  • the airbag 14 In this free, unfolded state, the airbag 14 can be filled very quickly with a desired volume of ambient air, for example with a volume of approximately 150 liters, and the fan 20 does not need to apply high pressure for this. This is because the airbag 14 is no longer in the container 18. Rather, the airbag 14 has already been deployed.
  • Fig. 9 the backpack 10 with the U-shaped airbag pocket is shown in a further perspective view.
  • This view shows particularly clearly how the zipper 64 is also kept closed or secured by means of the closure element 34, the zipper 64 closing an outlet opening of the container 18 in the closed position of the container 18 or the airbag pocket.
  • the actuating device 28 indicated with the handle 30 and the pull rope 36, which is coupled to the locking element 34 in such a way that the locking element 34 can be unlocked or opened by pulling on the handle 30.
  • the avalanche airbag system 12 in turn comprises the airbag 14 and the electric filling device 16 with the blower 20, which has the electric motor 22.
  • the airbag 14 and the electric filling device 16 with the blower 20, which has the electric motor 22.
  • the container 18 or the airbag pocket comprises a spring element with two brackets 72, 74 (cf. Fig. 11 ), which when the container 18 is brought into the closed position (cf. Fig. 10 ) to each other issue.
  • the spring element which comprises the two brackets 72, 74 is tensioned.
  • a wall material 76 of the container 18 can be designed to be flexible and can be made of a textile material and / or a flexible, film-like plastic material, for example. This is because the brackets 72, 74 ensure a certain shape of the container 18. Again, the spring element is held in the tensioned state by means of the closure element 34 (cf. Fig. 10 ).
  • the brackets 72, 74 then move away from one another, and the container 18 is placed in the in Fig. 11 shown open position brought.
  • the spring element with the two brackets 72, 74 is thus designed in the manner of a spring clip 78.
  • Fig. 11 the container is shown opened a bit. If, in the closed position of the container 18, areas of the brackets 72, 74 that abut one another are moved as far away from each other as possible and thus the container 18 is completely open, then tensioning the flexible sheet material 76 causes the airbag 14 to be ejected from the receiving space 50.
  • the brackets 72, 74 can in particular be brought into an extended position.
  • the flat structure can in particular be provided by at least one textile material made of fibers and / or by at least one film-like polymer material.
  • Fig. 11 the receiving space 50 of the container 18 can be seen, but for the sake of clarity the airbag 14 deployed from the receiving space 50 is not shown. Furthermore it is off Fig. 11 It can be seen that when the container 18 is brought into the open position or opened, the two brackets 72, 74 delimit an outlet opening of the container 18 through which the airbag 14 fixed in the receiving space 50 is deployed or ejected from the receiving space 50.
