EP3038897B1 - Activation device for triggering an automatic rescue means - Google Patents

Description

Technical area

The invention relates to an activation device for triggering a discharge of a gas from a storage container into a gas-filled rescue means, wherein the activation device comprises a detection element for determining the triggering time and a triggering element for the sudden opening of the storage container.

definitions

A life-saving device may be a lifejacket which, in particular, gives an additional buoyancy to a person who is in the water. Preferably, it is a garment in the form of a vest. This garment usually has armholes through which the arms can be passed, the remaining body parts, namely the back, chest and abdomen, being covered by the vest. Closure elements such as zippers, buckles or the like keep the lifejacket in the required position on the body.

Colloquially, the term life jacket is known. But this should also be understood as the lifejacket. Swimming aids can be confused with life jackets in terms of their appearance. Buoyancy aids are less buoyant than lifejackets.

Life jackets are known in different formations and with different buoyancy properties.

As part of a special specification, the lifejacket is able to turn and / or hold even a powerless person in a safe swimming position.

• 50N Auftriebskraft: Schwimmhilfe - nur für geübte Schwimmer in Ufernähe oder in Begleitung eines Sicherungsfahrzeuges; nicht ohnmachtssicher;
• 100N Auftriebskraft: Rettungsweste für Binnengewässer und geschützte Reviere, nur eingeschränkt ohnmachtssicher;
• 150N Auftriebskraft: Rettungsweste für alle Gewässer, ohnmachtssicher, allerdings eingeschränkt für Träger von schwerere wetterfester Kleidung;
• 275N Auftriebskraft: Rettungsweste auf hoher See und extremen Bedingungen in fast allen Fällen ohnmachtssicher, trotzt schwerer Bekleidung.

The appropriate size depends on the required buoyancy volume of the lifejacket. This is calculated by the total weight of the wearer including his clothing and equipment as well as the sea area. The following classifications are planned:

• 50N buoyancy: buoyancy aid - only for experienced swimmers near the shore or in the company of a security vehicle; not faint-hearted;
• 100N buoyancy: life jacket for inland waters and protected areas, only limited powerless;
• 150N buoyancy: Lifejacket for all waters, faint-conscious, but limited for wearers of heavier weatherproof clothing;
• 275N Buoyancy: Lifejacket on the high seas and in extreme conditions in almost all cases fainting, defying heavy clothing.

Rescue means in the present sense can also be devices that are attached to an object, for example, in order to prevent them, if they fall into a body of water, sinking to the bottom and can no longer be recovered.

State of the art

Rescue means for rescuing persons and animals, for example, involuntarily coming into contact with deep water, are known in different embodiments. Life-saving jackets are known as life-saving equipment.

The lifejackets can be subdivided by their buoyancy systems in solid vests and inflatable lifejackets. Solids vests have firmly integrated buoyancy means, whereby the west are relatively large volume.

This lifejacket is intended to protect the person or the animal from drowning and at least keep it on the water surface. Such life jackets are jacket-like (without sleeves) designed and fixed with one or more fasteners on the body of the wearer. In order to ensure that the lifejacket fits properly on the body, additional leg or crotch strap elements are provided which hold the lifejacket in position even when in contact with water. Preferably, these lifejackets on a corresponding signal color. In order to provide a safe position on the water even in the helplessness of the wearer, it is provided to arrange a collar element on the lifejacket, so that the person on the water surface so lying on his back comes in a stable position that the head area is supported and so the airways be kept free.

Inflatable lifejackets are usually worn folded small. In the case of use, the inflation is triggered by hand or by an automatic. This embodiment provides to provide a lifejacket in such a way that it does not hold any static buoyancy bodies outside the water. Rather, the buoyancy bodies are only generated when a corresponding contact with the water takes place. The triggering is usually done by a kind of sensor element, which is provided for example by a salt tablet (or other material that changes its properties in conjunction with water). This salt tablet releases a mechanism that causes a sudden release of CO2, which in one Reserved container is made possible in a body element. The body element is arranged around the neck like a tube. A brace-like construction (life-belt) secures the tubular construction to the wearer's body, especially when the gaseous agent has flowed into the body member.

Floating or buoyancy aids (so-called regatta, kayak, rower vests, etc.) have a similar structure. However, to ensure greater freedom of movement for the wearer, these have smaller buoyancy bodies of solids (approximate buoyancy 50 N). In addition, it usually lacks the appropriate fainting head support, namely a collar element.

For personal safety equipment, especially for water sports enthusiasts, such as yachtsmen or kayakers, personal lifejackets or swimming aids (also commonly known as regatta or kayak vests) are required by law.

In principle, one distinguishes between such safety equipment, which on the one hand is faint-hearted and on the other hand not faint-hearted; that is, the latter are unable to keep the subject's head safely clear of water and the respiratory tract when she is unconscious. Therefore, such swimming aids, such as Regattawesten, mainly used in sports, help is usually guaranteed quickly.

Furthermore, an inflatable device is known from the prior art which is worn by persons directly on the body. In this case, the rescue device can be tied like a belt around both the hip and around the abdominal area, whereby it fills with contact with the water correspondingly with a gas. For this purpose, body elements are provided which are belt-like arranged on the system, which are filled with the gaseous element.

Developments provide that the rescue means have electronic support elements.

The support elements are designed such that, for example, the water pressure is measured. Only at a certain water pressure then triggering or inflation of the body elements takes place. This device is for example from the US 6,246,329 B1 known.

However, in order to operate such a device, it is necessary that an electrical unit is arranged. These electrical units, which also include, among other things, a power supply and a timer (timing instrument) are arranged separately from the rescue means. The connections must be designed so that they are waterproof and functional over a long period of time, since generally life saving means of the above kind are either stored in rooms or crates for long periods of time or are in daily use and then have to provide their function in an emergency ,

If a person is at sea or in the water in an emergency position, it is necessary that this has a lifejacket attached to the body. If the person is able to keep himself afloat, life jackets with a buoyancy force of up to 100N are sufficient. But if this faints, so the lifesaving agent must provide so much buoyancy that keeps the body including water-soaked clothing over water. Life jackets with buoyancy forces of up to 100N can no longer fulfill this requirement. The person would go down. From the outset to wear life jackets, which have the corresponding buoyancy, is uncomfortable and not common in the sports field. Alternatively, so-called automatic lifejackets can be used.

The above rescue devices do not show the user if this is actually working. In the case of automatic lifejackets, for example, if a salt tablet, which is responsible for triggering the delivery of the gas stored in a container into the body elements, does not dissolve completely, no gas flows into the body element and the inflation does not take place. The rescue means thus has no function. Nevertheless, it is very clear to the observer that the function is given by the indication of the green indicators, which only confirm a partial function (for example, taut spring). A reliance and an absolute security are thus not given. For solid life jackets, only tactile and visual checks are performed.

Activation devices for triggering outflow of a gas from a storage container into a gas-filled lifejacket are already known from the prior art. They are used in the so-called automatic life jackets. This device has a detection and a triggering element. The detection element serves to determine the status of whether the rescue means has come into contact with water or not. A very simple and currently common solution is to use so-called salt tablets. These salt tablets dissolve on contact with the water and give the impulse given by a spring to a triggering element. The trigger element in turn is designed to strike an opening in a gas-filled cartridge (in the order of 20g to 40g), so that this cartridge abruptly in an emergency, that is, in contact with water, the stored gas in the body elements of the life jacket, as Buoyancy act, enters. Should the detection mechanism fail or a more rapid activation of the lifejacket occur, a hand-operated means is still provided which bridges the detection mechanism and immediately activates the triggering mechanism.

Such devices are widely used in such lifejackets. The salt tablet should have the property of always, that is always on contact with water to dissolve and then activate the trigger mechanism accordingly, so that the gas can escape. To ensure this are at least in the shipping sector, constant regular checks are necessary. These controls are also prescribed because it is not visible to the device, whether it actually works or not. It will then - at least at regular intervals - caused dry triggering, so that a new detection means and a new trigger mechanism must be used.

An alternative embodiment is from the EP 1 961 654 A1 known. For this purpose, a garment is proposed, which provides a buoyancy body, which is inflated in an emergency situation of the user. The emergency is determined by parameters such as salt or fresh water, residence time in the water, orientation in the water. If the emergency is determined by falling below one or more parameters, a time measurement starts in the formation of a countdown. If the countdown has expired without the parameters having changed, the triggering and thus the inflation of the buoyant body takes place. Various operating switches allow the setting of the countdown timer as well as the depth, which leads to tripping when exceeded.

Also from the US 2010/0167608 A1 as well as the US 2013/0109260 A1 For example, a device is known which then provides buoyancy means as the water pressure becomes higher. It can be set to the depth at which a timer (countdown) is activated, after the expiration of the lift is provided.

However, some devices also provide that the detection mechanism can be switched off. This measure is used when it is necessary that the automatic vest should not be triggered by splashing water or spray. This is done in the form of a split pin which stops the detection mechanism. The pins are usually marked in color, so that it is inevitable for the user to see from the outside that the detection mechanism is out of operation. This is especially the case when working in the Water area, for example, splash water area done and not every touch a popcorn-like explosion is desired.

Disadvantages of the invention

For the user, however, there is a need to always have the security in any situation that such lifejackets actually work. However, this is given only conditionally in the present known systems.

The automatic life jackets have the considerable disadvantage that they can not reliably provide security especially for longer storage time. The user can not ascertain and rely on the emergency equipment being actually operational in an emergency. The above life-saving appliances do not show the user if this is actually working. In the case of automatic lifejackets, for example, if a salt tablet, which is responsible for triggering the delivery of the gas stored in a container into the body elements, does not dissolve completely, no gas flows into the body element and the inflation does not take place. The rescue means thus has no function. Nevertheless, it is very clear to the observer that the function is given by the indication of the green indicators, which only confirm a partial function (for example, taut spring). A reliance and an absolute security are thus not given. For solid life jackets, only tactile and visual checks are performed.

On the other hand, however, it is desirable that the automatic vests do not necessarily trigger any immediate contact with water, for example splashing water that passes through the boat due to spray or short-term contact with water, where there is no danger to life (sailing dinghies or trapeze sails). However, since it is a purely mechanical system in which the detection means is dissolved with appropriate contact with water, this process can not be adapted to individual needs.

For many sports, such as rowing, windsurfing, kiting, kayaking, stand-up paddling, jet skiing, etc., or for children bathing the water contact is not an emergency situation, but a part of a sporting activity. The known from the prior art automatic lifejackets can not detect these situation differences, so that the lifejackets are not worn during the exercise of such sports.

Thus, no automatically inflatable lifejackets are known, which are worn in the aforementioned water sports or operations. Known are exclusively west with a low buoyancy of 50N, so-called kayak or Regattawesten, but in turn do not cover an emergency situation.

Object of the invention

The object of the invention is to provide a device in which automatic vests depending on individual use and need reliably provide the Rettungsungsmittelfunktion.

Solution of the task

The solution of the problem is provided by the features of claim 1 and claim 6.

Advantages of the invention

The essential idea of the invention is to adaptively replace previous systems which enable the triggering or inflation of automatic rescue devices. In this case, a reliable system is to be provided in the formation of a device to which the user of the rescue means can rely. This is achieved by providing an activation device having a detection device that is microprocessor-controlled. This control provides that by means of one or physical sensors, such as water contact, movement, pressure, temperature, etc. (optional or additive) can be determined, the then after appropriate evaluation and comparison with one or more predetermined tables or individually programmed or individually defined limit parameters , the tripping element for opening the storage containers, which are filled with gas, triggers. In one embodiment, it is provided that only one or a few physical quantities are measured, which are then compared with a table stored in the microprocessor control. If one or several of the values (limit value parameters of the sensors) are undershot, the detection device signals the triggering element to the triggering element, namely to start the impacting of the reservoir tank for the outflow of the gas into the means provided for the rescue means. These limit parameters are set according to the sport that is operated with the activation device. These can be determined individually or sport-specific, without the activation device must be operated.

Therefore, the activation device has no controls (except a tactile function to check the functionality), so that a malfunction before and also during the application, especially when playing sports, is excluded.

As a rescue means, a life jacket may be provided. Such with the inventive device brings with it the possibility that it can be worn in all sports that come into contact with water. The lifejacket then provides the necessary lift for an emergency of at least 150N and provides the necessary powerless collar function.

The inventive activation device can be attached as a so-called OEM product or subsequently to automatic lifejackets. It can be via a smartphone or a similar device operate via an interface arranged on the device, in the manner in which the triggering parameters (limit value parameters of the sensors) themselves are changed or are simply selected for the corresponding application (child, sport, etc.) via an application (app) can. The lifejacket wearer is not hindered by the designed as a buoyancy aid vest in his sports practice and still has the emergence of an emergency on a full-fledged rescue system.

A preferred embodiment provides that the user is warned by an acoustic signal that takes place in a few seconds, the explosive inflation of the rescue. A probe element provided on the device provides the user with the opportunity to stop the triggering operation before the beating-up of the storage container takes place. This may be the case if the sensors have detected appropriate moisture or water, but the user is not at all in danger of actually having to use the life-saving device.

The device itself consists essentially of two components, namely the detection device and the triggering element. The detection device is a preferably closed system, which is waterproof in a capsule-like design, for example, designed cylindrical, incorporated. Only one or a few touch elements serve to control the process accordingly. Signal elements assure the user of the actual current state. The sensor elements of the detection devices are also incorporated in this. They are thus considerably protected against mechanical loads. Nevertheless, these are due to the special design of the housing, which is formed namely slot-like, flooded by water. Thus, according to not only amounts of water, but also water temperature but also the movement can be detected accordingly.

The triggering mechanism itself adjoins the detection device directly, preferably also in the form of a cylinder. Corresponding ignition mechanisms, which provide electrical connection to the detection means are also part of the triggering mechanism. The ignition mechanism, in turn, provides for urging a bolt-like element at high speed over a short distance, which then strikes a corresponding hole in the storage container so that the gas stored in the storage container can accordingly discharge explosively into the intended areas of the life-jacket. After an ignition process, only the trigger mechanism must be replaced and the storage container also replaced, which then contains corresponding gas again.

The device is designed such that it provides appropriate adapter elements, so that a mounting to almost any standard automatic rescue vest is possible. These connectors differ from any type of automatic rescue vest. In order to ensure a large adaptability, the device is designed so that in a very simple way any Konnektierungselement can be accommodated.

A further advantageous embodiment provides that the user can set the default values, which specify when a corresponding triggering mechanism takes place, itself. This setting can be done via electronic aids, such as a USB cable to a computer but also via Bluetooth interfaces with smartphones, tablet PCS or the like.

However, since the energy of the device is to be provided over a longer period of time, it must be ensured that the energy is not heavily loaded even by data transmission. For this purpose, it is provided according to the invention, instead of the usual transmission techniques as Interfache example light flash frequencies, as it is known for example in electronic banking today to use. A corresponding smartphone or tablet PC is held to the device and by appropriate flash technology, which is received by a light sensor within the activation device, the data to be transmitted. The data contain the previously defined or defined for each sport limit parameters that are necessary when falling below the actual actual values for the activation of the activation device.

However, if critical values are set which can be life-threatening, the user is warned against choosing such values. A system device may provide that the values are returned to normal values automatically again. On the other hand, by confirming again, the user must clearly and unambiguously acknowledge that he wants exactly these values.

In this way it is possible to provide an individually adjustable automatic vest based on the years of experience of the automatic vests known in the art. By an adaptive means, which replaces the conventional triggering mechanism, thus an individual adjustable lifejacket is provided, which can be used for different needs. So it is also conceivable that such lifejacket is used for dinghy sailing and then first become active when in fact there is a life-threatening situation.

Alternative embodiments may also provide that the situation is analyzed based on the detection of the physical data and only so much gas is released into the chambers of the lifejacket, that just a buoyancy is achieved, because for many situations, it is not necessary that buoyancy forces in magnitude be provided by over 200N. In many cases it is sufficient to provide buoyancy forces between 50N and 75N or 100N.

In contrast to conventional devices known from the prior art, the device according to the invention provides the rescue function only when an emergency actually exists.

The device has a power supply, for example in the formation of a lithium-ion battery, which provides reliable energy for several years without maintenance. Preferably, the device turns on independently if necessary and - after a defined period of non-use - again off. A clear acoustic and optical communication device confirms the readiness of the device when manually polled by confirming a test switch. This includes a self-test by checking the system condition, the battery's readiness, the sensors, and the proper insertion of the pyrotechnic actuator.

Upon reaching a life-threatening situation, the device initiates a pyrotechnic action based on the million-proven automotive airbag deployment technology. This device releases a spring mechanism, which in turn pierces the CO2 cartridge with a spike and thus this CO2 flows into the rescue means and this inflates automatically and thus provides a buoyant body.

The device can be made operational again by simply replacing the pyrotechnic trigger.

• Laufende Berechnung des Ertrinkungsrisikos: Der eingebaute Mikrocomputer wertet laufend die Daten verschiedener berührungsfreier Sensoren aus und errechnet dadurch das aktuelle Ertrinkungsrisiko des Trägers.
• Selbstständige Lernfähigkeit durch Interaktion mit dem Träger: Das System kündigt eine anstehende Rettungsaktion durch klare Tonsignale an. Der Träger kann nun durch Knopfdruck oder durch Aussteigen aus dem Wasser die Rettungsaktion abbrechen. Solche Interaktionen werden berücksichtigt, womit sich das System an die Fähigkeiten des Trägers anpasst.
• Robuste Airbag-Technologie aus der Fahrzeugindustrie: Die Auslöseeinheit besteht aus einem einfachen und auswechselbaren System, welches auf der bewährten Airbag-Technologie von Fahrzeugen basiert.
• Konfiguration von Rettungswesten mit Smartphone entspricht dem heutigen Trend: Obwohl die Vorrichtung ohne weitere Bedienung eingesetzt und betrieben werden kann, sind trotzdem spezifische Kundeneinstellung über ein Smartphone möglich.
• Adaptierung von bewährter und robuster Technologie für die Datenübertragung: Die Datenübertragung der Konfigurationsdaten vom Smartphone zu der Vorrichtung erfolgt bevorzugt über optische Blinksignale des Displays eines Smartphones oder WEB-Portals. Diese alte und rudimentäre Technologie (vergleichbar zur IR Fernbedienung von Fernsehgeräten) wurde für die Verbindung von zwei High-Tech Geräten entsprechend angepasst und ermöglicht eine äusserst robuste und einfache Kommunikation. Es sind weder Kabel, Zusatzgeräte oder sogar Einstellungen an den Geräten nötig. Die Verbindung ist intuitiv, unabhängig vom Smartphone Typ und kann sogar über alle gängigen Computerbildschirme (Röhren oder LCD) via einer WEB Page erfolgen.

The device thus has essentially the following advantages:

• Ongoing calculation of the drowning risk: The built-in microcomputer continuously evaluates the data from various non-contact sensors and calculates the current drowning risk of the carrier.
• Independent learning ability through interaction with the wearer: The system announces an upcoming rescue operation by clear sound signals. The wearer can now cancel the rescue operation by pressing a button or getting out of the water. Such interactions are taken into account, with which the system adapts to the abilities of the wearer.
• Robust airbag technology from the automotive industry: The trip unit consists of a simple and interchangeable system, which is based on the proven airbag technology of vehicles.
• Configuration of lifejackets with smartphones corresponds to the current trend: Although the device can be used and operated without further operation, specific customer settings via a smartphone are still possible.
• Adaptation of proven and robust technology for data transmission: The data transmission of the configuration data from the smartphone to the device preferably takes place via optical flashing signals of the display of a smartphone or WEB portal. This old and rudimentary technology (similar to the IR remote control of televisions) has been adapted for the connection of two high-tech devices and allows a very robust and simple communication. There are no cables, accessories or even settings on the devices needed. The connection is intuitive, independent of the smartphone type and can even be carried out via all common computer screens (tubes or LCD) via a WEB page.

It was intentionally waived any further operation, to avoid mishandling and.to increase the acceptance of users. As a consequence, the system does not have a main switch. The activation and deactivation takes place automatically.

However, the invention is not limited only to the application for automatic lifejackets. Rather, it is suitable wherever triggering mechanisms have to be provided in a very simple manner but reliably, the triggering taking place in dependence on defined or selectable physical quantities.

For example, such rescue means may be attached to luggage. If they get wet, conventional life-saving appliances will start. The However, the device according to the invention is adjusted in such a way via the application that spray water, rain etc. or even through the water (for example a flow) do not lead to triggering. It is triggered when the sinking of the protected good threatens or has occurred and thus the good in itself would be irretrievably lost. By triggering the good drives back to the water surface and can be removed from there. Especially important objects, such as flare guns, binoculars, detection systems, defense means, can be protected from irreversible loss, although they are exposed to the weather all the time, ie the rain, spiky water or permanent water contact.

Description of an embodiment

In Fig. 1 to 6 the inventive activation device 1 is shown in two embodiments. It consists essentially of the detection element 2 and the triggering element 3. Both elements, namely the detection element 2 and the triggering element 3 are configured substantially cylindrical in these embodiments and arranged on a common axis 4. Indication elements 5, in the design of display elements, such as LED lights or the like, indicate the status of the activation device 1 at. In this case, the user can recognize whether the activation device 1 operates reliably and actuates the corresponding triggering mechanism in the event of an emergency or if there are malfunctions.

In addition, an actuating element 6 is provided in the form of a button. Upon actuation of this actuator 6, the trigger mechanism is interrupted. The user recognizes by a sounding signal that the triggering will take place in the shortest possible time and can thus interrupt the actuation.

The activation device 1 has neither a main switch nor other switching elements. It is constantly in use and can be switched off exclusively by removing the battery, which guarantees a long-term duration. Alternatively, a sensor is provided which detects the use. For example, if the device is in a cabinet, the activation device 1 switches off automatically.

In the Fig. 2 and 5 In essence, the housing 7 of the detection element 2 is shown.

The housing 7 of the detection element 2 is preferably made of impact-resistant plastic. It is a one-piece component, which is watertight sealable after insertion of the electronics provided in the housing 7 cavity 8. The sealing is preferably carried out by gluing or ultrasonic welding. So the case is absolutely waterproof and can only be replaced as a whole component.

On the housing wall 9 openings 10 are provided, which are arranged such that they can be flushed by fluid, in particular water. This causes behind the openings 10, in turn, a further cavity 11 is provided, on which the corresponding sensors 12, which are necessary for the detection element 2, are arranged. These are so well protected against mechanical damage.

In Fig. 3 and 6 In addition, the trigger element 3 is shown. It has a housing 15 on which an adapter element 16 and a detonator 17 with a firing pin 18 is arranged (shown in FIG Fig. 2 and 5 ). The housing 15 is connected on its one end face 19 with the detection element 2, whereas it screwed on the other end face 20 via the adapter element 16 with the coupling element 13 to a life jacket.

The screw connection is designed such that the firing pin 18 at least indirectly at the opening of a storage container 14 which is filled with gas, or he gives a prestressed firing pin accordingly free

The coupling element 13 is in itself a component which is coupled to the lifejacket. This is a typical component, which is also used when the conventional release form is done with, for example, a salt tablet. This coupling element 13 is thus manufacturer-dependent and serves, on the one hand, to effect an opening of the storage container 14, which is filled with gas, and, on the other hand, serves for manual triggering with a gripping element, which is connected to the coupling element 13 the rescue mission is possible. It is therefore also the task of the activation device 1 that they can be adapted via the corresponding adapter element 16 to any embodiment of coupling elements 13, regardless of their manufacturer.

In Fig. 2 and 5 also the arrangement of a part of the triggering element 3 with respect to the detection element 2 is shown. Depending on the configuration of the connection element on the lifejacket, the corresponding adapter element 16 is designed differently. At least the interior design of the cavity 11 of the detection element 2 is shown schematically. Another cavity 8 of the detection element 2 is occupied by a circuit board 21. This board 21 represents the microprocessor-controlled release system for lifejackets. The sensors 12 are directly connected to the board 21, so that they can be inserted together as a unit in the cavity 8. A battery 23 ensures a reliable voltage over a further period of time.

Due to the relatively high short circuit current, which is necessary for the ignition, that is, the knocking of an opening in the storage container, only so-called wound batteries can be used or the circuit is designed accordingly that high discharge currents are available. These designs can provide a typical discharge current of 1000mA put. Since these are also available in the range of 3V, the voltage for the operation of the microprocessor can be used. An operating time of about 2 to 3 years is guaranteed in any case.

The indication elements 5 are likewise connected directly to the circuit board 21. These can be aligned in such a way that they can then be contacted with the housing front side. Also, the confirmation element 6 is part of the board 21st

The cavity 8 is occupied for the most part of the board 21 with the battery 23. As already described above, but has a part of the housing circumference 9 openings 10, within which then the sensors 12 are arranged. A corresponding grid serves to protect the sensors 12 from corresponding mechanical damage. This results within the cavity 8 of the already mentioned further cavity 11. The cavity 8 and the cavity 11 are fluidly completely separated with each other, so that the sensor 12 is exposed according to the water, whereas the cavity 8 is formed completely fluid-tight.

A contact pin 24 also extends away from the circuit board 21. This serves to provide an electrical connection to the triggering element. The electrical connection takes place between the contact pin 24 and the squib 18. At corresponding excess thresholds, an electrical impulse occurs on the primer, which in turn explodes and abruptly drives a pin-like formation in the opening of the storage container 14 with the gas.

Preferably, the connection between the detection element 2 and the trigger element 3 is also configured fluid-tight.

Training according to 4 to 6 provides that in the region of the detection element 2, a retaining ring 25 is provided which is suitable for the indication element 5 is visible to the user and that the retaining ring 25 the provided by the rescue means material, such as fabric, between them and the detection element 2 safely encloses.

In Fig. 7 the application of the activation device 1 is shown. The activation device 1 is arranged on an automatic vest A. It is fixed to the automatic vest A via appropriate adapter elements, which will be described in more detail later. The user wearing the automatic vest can recognize via the indicators 5 whether the activating device 1 works reliably. In addition, he can retrieve data about the activation device 1 via, for example, a smartphone S or comparable devices via a corresponding transmission technology U. Data may be, for example, operating state, state of charge of the battery or the like. In addition, the tripping parameters can be adjusted depending on the embodiment.

The illustrated activation device 1 is simply screwed to the intended location on the automatic vest A. It replaces the traditional release mechanism and can replace it without any additional tools.

The actuating element 6 can also be provided for manually actuating the triggering mechanism if the sensors 12 have not yet detected the corresponding data or if the limits of the existing data have not yet been exceeded. Alternatively, the manual release mechanism - as before - be arranged on the coupling element 13.

Another application of the activation device 1 is in Fig. 8 shown. The activation device 1 is designed such as, for example, in the Fig. 1 to 7 is shown, but with the difference that this activation device 1 is attached to a buoyancy body 30 on an object by means of a belt member 31. Activation device 1, belt member 31 and buoyancy body 30 form a unit. The activation device 1 triggers when falling below at least one limit value parameter a sensor 12, the inflation of the buoyancy body 30 from. This means that when the object G is under water that it passes through the buoyancy body 30 back to the water surface. However, the activation device 1 is preferably defined in such a way that there is no triggering in the event of splashing water, rain or even being carried by a river or swimming on the water surface. Predetermined applications (software app) provide a corresponding selection for the application, so that a simple configuration of the activation device 1 is possible.

Preferably, the activation device 1 is formed together with the buoyancy body 30 as a belt, so that it can be easily attached to an object G. Since activation device 1 and buoyancy body 30 are scalable in size, an attachment to different objects - even of different sizes - is possible. In Fig. 8 Therefore, only one possible embodiment is shown.

Basically, the device is completely configured and shipped ready. This configuration consists of a general presetting of the parameters. The user does not have to configure their own device, but can be sure that the system is ready to use right from the start and ready for use at any time.

However, in order for a polysportive user or user to be able to optimize his activation device corresponding to the respective application-specific boundary conditions for securing objects, the system provides a wireless configuration option that can be configured with the smartphone (or a commercially available laptop). The use of the personal smartphone allows a specific configuration of the device and offers the following technical and commercial advantages:
By personalizing the trigger parameter, the device can be adapted to specific sports applications and user profiles. Example:
Surfers are regularly rinsed by waves in several meters depth, which is no reason for a rescue operation. The surfers use the light to orient themselves and swim to the water surface. The situation only becomes critical when the rider loses his orientation and floats down or otherwise does not move to the surface of the water. This dangerous situation can detect the device through the specific configuration and, if necessary, initiate a rescue operation.

The device has a software application that runs on tablets, smartphones or even computers. It invites downloading through an attractive design and provides some useful features, even without the device. medical information relating to water sports accidents, emergency numbers, first aid measures, information on lifejackets (including competitors), but also e.g. Links to qualified shops and other related websites.

With the shop function of the software, spare parts for the device as well as for other automatic lifejackets can be ordered at the push of a button.

A direct communication with the customer or the "community" is also provided.

This software is offered in an application (APP) for various platforms (iOS, Android, Windows etc.).

The configuration setting of the device can be done for example via a data transmission protocol. As data protocols NFC, Bluetooth, WLAN or the like can be provided. However, in order for the device to require as little power as possible, a light sensor is provided on the activation device, which receives light pulses transmitted to the light sensor. The device decodes these light pulses used for configuration (e.g. Setting limit values with respect to the triggering time) of the device.

Since the configuration of the device via device-independent light pulses on the screen, the programming can be done from all platforms and via a web portal / webshop via the screen. For this it is only necessary that the device is held with the sensor close to the screen, that the light pulses are transmitted.
