Description
Die vorliegende Erfindung betrifft ein Notauslösesystem für ein oder mehrere Wintersportgeräte, wie Skier, Skistöcke, Snowboards, Bindungen und/oder Schuhe für Skier oder Snowboards. Sie betrifft insbesondere ein elektrisch ansteuerbares Notauslösesystem, welches in Lawinensituationen und auch in anderen Notsituationen (z. B. wenn eine manuelle Öffnung der Bindung nicht möglich ist) eine derartige Trennung realisiert. Die vorliegende Erfindung betrifft zudem ein Verfahren zum Auslösen und ein Verfahren zum Herstellen von Wintersportgeräten.The present invention relates to an emergency release system for one or more winter sports equipment, such as skis, ski poles, snowboards, bindings and / or shoes for skis or snowboards. In particular, it relates to an electrically triggerable emergency release system which realizes such a separation in avalanche situations and also in other emergency situations (eg when manual opening of the binding is not possible). The present invention also relates to a method for triggering and a method for producing winter sports equipment.
Nach einer schweizerischen Statistik für die Jahre 1980- 1999 (
In einer Lawinensituation ist es daher von größter Bedeutung, möglichst lange (am Besten vollständig) an der Schneeoberfläche zu bleiben. Eine Empfehlung für die Lawinensituation lautet daher, sich durch Schwimmbewegungen an der Oberfläche zu halten (fließende Schneemassen weisen eher die Eigenschaften eines Fluids auf). Damit erstens effektive Schwimmbewegungen überhaupt möglich sind und zweitens keine Ankerwirkung durch Ski und Stöcke bzw. durch das Snowboard entstehen kann, ist es zwingend notwendig, Person und Ausrüstung voneinander zu trennen. Durch den sog. inversen Segregationseffekt werden große Teile (wie der Körper eines Skifahrers) eher an die Oberfläche gespült. Eine Verankerung z. B. durch den Ski mit tieferen Schneeschichten wirkt sich auf diesen Effekt nachteilig aus. Der versierte Sportler kann zunächst versuchen, durch eine rasante Schussflucht den Schneemassen zu entkommen. Sobald ihm/ihr dies aber misslingt, müsste die Trennung von seinen Gerätschaften in möglichst kurzer Zeit auf seinen "Auslösebefehl" hin erfolgen. Die Trennung vom Ski durch das Auslösen der Skibindung ist in derartigen Situationen i.d.R. ausgeschlossen. Grund: im fließenden Medium "Lawine" treten zunächst nur sehr geringe Kräfte auf, welche die heute üblichen kraft- bzw. momentengesteuerten Skibindungen nicht zur Auslösung bringen können. Wenn sich die Schneemassen soweit verdichtet haben, dass die entstandenen Kräfte zu einer Auslösung ausreichen, ist es für eine Befreiung meist zu spät.In an avalanche situation, it is therefore of paramount importance to stay on the snow surface for as long as possible (preferably completely). A recommendation for the avalanche situation is, therefore, to keep the surface by floating movements (flowing snow masses have rather the properties of a fluid). Firstly, effective swimming movements are possible at all and secondly no anchor effect can arise through skis and poles or through the snowboard, it is imperative to separate the person and equipment from each other. Due to the so-called inverse segregation effect, large parts (such as the body of a skier) are rather flushed to the surface. An anchoring z. B. by the ski with deeper snow layers has a negative effect on this effect. The savvy athlete can first try to escape the snow masses by a rapid escape from the gunfire. But as soon as he / she fails, the separation of his equipment in the shortest possible time on his "trigger command" would have to take place. The separation from the ski by triggering the ski binding is usually excluded in such situations. Reason: in the flowing medium "avalanche" only very small forces occur at first, which can not bring about the force or torque-controlled ski bindings that are common today. If the masses of snow have condensed so much that the resulting forces are sufficient for a release, it is usually too late for a liberation.
Um die größte Gefahr - den Erstickungstod - zu verhindern, wird unter anderem versucht, den Verschüttungsgrad mit Hilfe zusätzlicher Sicherheitsausrüstung wie dem Lawinen-Airbag (umfassend zwei zusammengefaltete Kunststoffballons, die in einem Rucksack seitlich integriert sind und nach dem Ziehen einer Reißleine in 2-3 Sekunden mit 150 Liter eines Stickstoff-Luft-Gemischs aufgeblasen werden; siehe auch: www.abs-lawinenairbag.de) oder der Rettungsweste Avagear™ (hier umschließen die Ballons die Schulter- und Halsregion; siehe auch: www.avagear.net) zu verringern; die Wirksamkeit beider Vorrichtungen beruht auf dem Prinzip der zuvor genannten inversen Segregation in granularen Strömungen.In order to prevent the greatest danger - suffocation - it is attempted, inter alia, to increase the level of burial using additional safety equipment such as the avalanche airbag (comprising two folded plastic balloons laterally integrated in a backpack and pulling a ripcord in 2-3 Seconds inflated with 150 liters of a nitrogen-air mixture, see also: www.abs-lawinenairbag.de) or the life jacket Avagear ™ (here the balloons enclose the shoulder and neck region, see also: www.avagear.net) reduce; the effectiveness of both devices is based on the principle of the aforementioned inverse segregation in granular flows.
Erste Feldversuche und Auswertungen von Unfalldaten durch das Eidgenössische Institut für Schnee- und Lawinenforschung lassen vermuten, dass Airbag-Nutzer ein insgesamt niedrigeres Sterblichkeitsrisiko bei Lawinenunfällen haben. Dennoch kann sich insbesondere die Ankerwirkung durch Ski und Skistöcke nachteilig auf den inversen Segregationseffekt auswirken und Schwimmbewegungen des verunfallten Skifahrers zum Verbleib an der Schneeoberfläche unterbinden.First field tests and analyzes of accident data by the Swiss Federal Institute for Snow and Avalanche Research suggest that airbag users have an overall lower mortality risk in avalanche accidents. Nevertheless, in particular the anchor effect by skis and ski poles can adversely affect the inverse segregation effect and prevent swimming movements of the injured skier to remain on the snow surface.

This can have a simple or more complex, compound form. In this case, a section, for example partially or completely annular, cylindrical, conical, frusto-conical and / or pylon-shaped. Such a connection device may, for. B. by Ur- or forming, cutting, bending, and / or machining in a known manner. The dimensions, ie z. As the sheet thickness and the outer dimensions, so dimensioned that a deformation can not take place by a recoverable in normal driving force, but by a recoverable by triggering the drive force.
Vorzugsweise hat die Verbindungseinrichtung ein proximales Ende mit einem ersten Außenmaß und ein distales weiter bevorzugtes gekrümmtes und/oder gekröpftes Ende mit einem zweiten Außenmaß, welches größer ist als das erste Außenmaß, wobei sich das distale Ende im wesentlichen radial in oder an einem der zwei Elemente abstützt. Besonders bevorzugt ist hierbei eine pylonenförmige Verbindungseinrichtung, bei der jedoch die bei Pylonen übliche Standfläche ringförmig ausgebildet sein kann. Eine derartige Form hat den Vorteil, dass über einen konifizierten Abschnitt eine Kraft von dem einen zum anderen in Verbindung gebrachten Element begradigt, d. h. ohne erhebliche Winkel, übertragen werden kann. Es ist also weiter bevorzugt, dass die Verbindungseinrichtung einen intermediären Abschnitt aufweist, dessen Außenmaß sich zumindest teilweise kontinuierlich vom proximalen zum distalen Ende hin vergrößert.Preferably, the connecting means has a proximal end of a first outer dimension and a distal more preferred curved and / or cranked end having a second outer dimension greater than the first outer dimension, the distal end being substantially radially in or on one of the two members supported. Particularly preferred in this case is a pylon-shaped connecting device, in which, however, the usual standing in pylons footprint may be annular. Such a shape has the advantage that over a butted portion a force is straightened from one element brought to the other, i. H. without significant angle, can be transmitted. It is therefore further preferred that the connecting device has an intermediate section whose external dimension increases at least partially continuously from the proximal to the distal end.
Weiter bevorzugt umfasst die Treibeinrichtung pyrotechnisches Material, welches in Form einer Pille bzw. Kapsel eingeschlossen ist. Die Pille und ihre Aufnahme sind bevorzugt so ausgebildet, dass sie nach einer erfolgten Zündung leicht ersetzt werden können, wobei die weiteren Elemente vorzugsweise ebenfalls leicht in die ursprüngliche Position bringbar sind oder leicht austauschbar sind.More preferably, the driving device comprises pyrotechnic material, which is enclosed in the form of a pill or capsule. The pill and its receptacle are preferably designed so that they can be easily replaced after ignition has taken place, wherein the further elements are preferably also easily brought into the original position or are easily replaceable.
Die vorzugsweise geringe Größe bzw. Masse der Treibeinrichtung hat den Vorteil, dass Sicherheitsvorschriften einfach eingehalten werden können, wodurch das erfindungsgemäße Notauslösesystem einfach transportiert werden kann. Zudem ist es vorteilhaft wenn aufgrund der geringen Masse der Treibeinrichtung auf Abdeckungen gegen Splitterbildung verzichtet werden kann.The preferably small size or mass of the driving device has the advantage that safety regulations can be easily adhered to, whereby the emergency release system according to the invention can be easily transported. In addition, it is advantageous if, due to the low mass of the driving device, it is possible to dispense with splintering covers.
Um die relativ geringe Sprengwirkung der Treibeinrichtung mit vorzugsweiser geringer Masse effektiv auszunützen, ist es bevorzugt, dass Dichtungen ein unkontrolliertes Entweichen des erzeugten Treibgases vermindern bzw. verhindern. Zudem oder alternativ ist es bevorzugt, wenn die Im Auslösefall zu bewegenden Teile eine geringe Masse haben, um ein schnelles Beschleunigen der Teile zu erreichen, wodurch eine schnelles Auslösesystem bereit gestellt werden kann.In order to effectively utilize the relatively low explosive effect of the propulsion device, preferably of low mass, it is preferred that seals reduce or prevent uncontrolled escape of the propellant gas produced. Additionally or alternatively, it is preferred that the parts to be moved in the case of triggering have a low mass in order to achieve a rapid acceleration of the parts, whereby a fast triggering system can be provided.
Zudem hat die geringe Größe bzw. Masse der Treibeinrichtung den Vorteil, dass das erfindungsgemäße System sehr klein (um die Treibeinrichtung herum) konstruiert werden kann, d. h. das erfindungsgemäße System kann auch als Nachrüstkomponente realisiert sein. Beispielsweise kann das erfindungsgemäße System als zusätzliches Notauslösesystem in einer Halteschlaufe einer bekannten Bindung (z. B. Skibindung oder Snowboardbindung) integriert werden, wobei der Verschluss der Bindung erhalten bleibt. Eine Neukonstruktion der Bindung kann so vermieden werden.In addition, the small size or mass of the driving device has the advantage that the system according to the invention can be constructed very small (around the driving device), d. H. The system according to the invention can also be realized as a retrofit component. For example, the system according to the invention can be integrated as an additional emergency release system in a retaining loop of a known binding (eg ski binding or snowboard binding), whereby the closure of the binding is retained. A new construction of the binding can be avoided.
Bevorzugt weist die Treibeinrichtung eine einseitig zu einem Kolben geöffnete Hülse auf, vorzugsweise aus expandierbarem Material, wie beispielsweise Metall, wobei die Treibeinrichtung ferner so angeordnet bzw. ausgebildet ist, dass sie bei ihrer Auslösung den Kolben betätigt. Vorzugsweise ist eine die Hülse umgebende Dichtung vorgesehen, die sich in einer Halteeinrichtung befindet und die so ausgebildet bzw. angeordnet ist, dass die Hülse bei oder nach der Auslösung der Treibeinrichtung expandiert und dabei die Dichtung nach außen drückt, um eine Abdichtung nach außen zur Halteeinrichtung weiter zu unterstützen.Preferably, the driving device has a sleeve which is open on one side to form a piston, preferably made of expandable material, such as metal, wherein the driving device is furthermore arranged or designed such that it actuates the piston when it is triggered. Preferably, a seal surrounding the sleeve is provided, which is located in a holding device and which is designed or arranged so that the sleeve expands during or after the triggering of the drive means and thereby pushes the seal outwardly to a seal outwardly to the holding device continue to support.
Vorzugsweise ist der Kolben so ausgebildet bzw. angeordnet, dass er nach seiner Auslösung bzw. Betätigung die Verbindungseinrichtung löst. Dafür kann er nach seiner Auslösung bzw. Betätigung zumindest über den intermediären Abschnitt der Verbindungseinrichtung gleiten und beim Fortschreiten der Bewegung das distale Ende der Verbindungseinrichtung nach innen bewegen und außer Eingriff bringen. Der Kolben ist dafür zumindest teilweise hohl ausgeführt, wobei der Hohlbereich ein Außenmaß haben sollte, dass der Kolben ohne größere Probleme über das proximale Ende der Verbindungseinrichtung gleiten kann, dann jedoch mit dem Hohlbereich zumindest einen Teil des intermediären Bereichs der Verbindungseinrichtung vorzugsweise radial nach innen verformt, um weiter das distale Ende ebenfalls radial nach innen und schließlich mit dem weiteren Gleiten des Kolbens über den intermediären Abschnitt der Verbindungseinrichtung außer Eingriff zu bringen und so eine Trennung der mittels der Verbindungseinrichtung verbundenen Elemente hervorzurufen.Preferably, the piston is designed or arranged so that it triggers the connection device after its release or actuation. For this he can slide after its release or actuation at least over the intermediate portion of the connecting device and move the distal end of the connecting device inward and disengage the progression of the movement. The piston is at least partially hollow, wherein the hollow portion should have an outer dimension, that the piston can slide over the proximal end of the connecting device without major problems, but then with the hollow portion at least a portion of the intermediate portion of the connecting device, preferably radially to inwardly deformed to further disengage the distal end also radially inwardly and finally with the further sliding of the piston over the intermediate portion of the connecting means to cause separation of the members connected by the connecting means.
Weiter kann ein Führungsrohr vorgesehen sein, welches dem einen der beiden zu verbindenden Elemente zuzuordnen ist, an bzw. in das die Verbindungseinrichtung eingreift, in dem vorzugsweise der Kolben gleitet und gegen den sich weiter bevorzugt die Dichtung radial nach außen abstützt. Damit können auf kleinstem Raum die genannten Teile in Wirkverbindung gebracht werden.Further, a guide tube may be provided which is assigned to the one of the two elements to be connected to or in which the connecting device engages, in which preferably the piston slides and against which more preferably the seal is supported radially outward. Thus, the said parts can be brought into operative connection in a small space.
Die Treibeinrichtung ist bevorzugt manuell und/oder automatisch auslösbar. Die Signalübertragung erfolgt dabei elektrisch, elektronisch, akustisch und/oder über Infrarot. Die Notauslösung ist ferner ausgebildet bzw. geeignet, zusammen mit einem oder durch eine Auslösung eines weiteren Rettungssystems, wie eines ABS-Lawinen-Airbags oder der Rettungsweste Avagear™, ausgelöst zu werden. Somit könnte ein integriertes Rettungskonzept mit einer Auslöser- bzw. Triggereinrichtung bereitgestellt werden, wobei alle Chancen zur Rettung genutzt werden und insbesondere die Verankerung eines Unfallopfers durch seine Wintersportausrüstung vermieden wird. Somit kann das zuvor erwähnte Prinzip der inversen Segregation in granularen Strömungen ungestört genutzt werden. Alternativ oder zusätzlich kann das Notauslösesystem durch mindestens ein auf biologischen Daten (z. B. EEG, EMG) beruhendes und/oder durch eine Sprachsteuerung ausgelöstes Triggersignal in den Auslösezustand versetzt werden. Insbesondere kann nach einer bevorzugten Ausführungsform ein Triggersignal über eine Stimme bzw. einen Stimmbefehl ausgelöst werden. Um ein ungewolltes Auslösen zu verhindern, kann eine Spracherkennung beispielsweise einen Wortlaut erkennen der einem Triggersignal zugeordnet ist. Alternativ oder zusätzlich kann die Spracherkennung ein "Stressmuster" in der Stimme detektieren, sodass die Auslösung vorzugsweise nur in Notsituationen erfolgt.The driving device is preferably manually and / or automatically triggered. The signal transmission takes place electrically, electronically, acoustically and / or via infrared. The emergency release is also designed to be triggered together with or through the deployment of another rescue system, such as an avalanche airbag or Avagear ™ lifejacket. Thus, an integrated rescue concept could be provided with a triggering device, taking advantage of all the chances of rescue and, in particular, avoiding the anchoring of an accident victim by his winter sports equipment. Thus, the previously mentioned principle of inverse segregation in granular flows can be used undisturbed. Alternatively or additionally, the emergency triggering system can be set into the triggering state by at least one triggering signal based on biological data (eg EEG, EMG) and / or triggered by a voice control. In particular, according to a preferred embodiment, a trigger signal can be triggered via a voice or a voice command. To prevent unwanted triggering, for example, speech recognition can recognize a wording which is assigned to a trigger signal. Alternatively or additionally, the speech recognition can detect a "stress pattern" in the voice, so that the triggering preferably takes place only in emergency situations.
Die Erfindung betrifft ebenfalls Wintersportausrüstung, wie Skibindung, Skischuh, Skistock und/oder Snowboardbindung, mit dem zuvor und nachfolgend beschriebenen Notauslösesystem.The invention also relates to winter sports equipment, such as ski binding, ski boot, ski pole and / or snowboard binding, with the emergency release system described above and below.
Vorzugsweise wird die Erfindung in einem Fersenniederhalter einer Skisicherheitsbindung, in dem das Notauslösesystem eingesetzt ist, verwendet. Zum einen kann dadurch nach der Auslösung des Notauslösesystems eine vorhandene Einstellfeder durch eine weitere Verspannung von außen, vorzugsweise durch eine Einstellschraube, wieder gespannt werden. Zum anderen kann auch ein dort ggf. vorhandener Fangriemen gelöst werden.Preferably, the invention is used in a heel down device of a ski safety binding in which the emergency release system is used. On the one hand, an existing adjusting spring can be tensioned again by a further tension from the outside, preferably by an adjusting screw, after the emergency triggering system has been triggered. On the other hand, a lanyard possibly existing there can be solved.
Der Fersenniederhalter hat üblicherweise einen Fersenniederhalterbacken und die bereits erwähnte Einstellfeder zum Einstellen der maximalen Haltekraft des Fersenniederhalterbackens bis zur bindungsbetätigten Auslösung. Vorzugsweise stützt sich die Einstellfeder direkt oder indirekt zumindest gegen die Verbindungseinrichtung ab und hebt durch eine Auslösung der Treibeinrichtung diese Abstützung der Einstellfeder auf. Dabei wird die Einstellfeder entlastet und damit der Fersenniederhalterbacken freigegeben.The heel downholder usually has a heel downholder jaw and the previously mentioned adjustment spring for adjusting the maximum holding force of the heel downholder jaw until the binding-actuated release. Preferably, the adjusting spring is supported directly or indirectly at least against the connecting device and lifts by releasing the driving device to this support of the adjusting spring. In this case, the adjusting spring is relieved and thus released the heel downholder jaws.
Bevorzugt ist alternativ, weiter bevorzugt zusätzlich ein Skistock mit einem erfindungsgemäßen Notauslösesystem versehen, wobei das Notauslösesystem geeignet ist, eine Handschlaufe und/oder einen Griff von zumindest einem wesentlichen übrigen Teil des Skistockes zu trennen.Preferably, alternatively, more preferably additionally a ski pole is provided with an emergency release system according to the invention, wherein the emergency release system is adapted to separate a hand strap and / or a handle of at least one essential remaining part of the ski pole.
Auch eine Snowboardbindung kann mit einem erfindungsgemäßen Notauslösesystem versehen sein, wobei das Notauslösesystem weiter bevorzugt geeignet ist, einen Feststellriemen dieser Bindung zu trennen.A snowboard binding may also be provided with an emergency release system according to the invention, wherein the emergency release system is more preferably suitable for separating a fastening strap of this binding.
Das System kann kombiniert werden mit einer sich im Auslösefall ganz leicht abwickelnden Verbindungsschnur, die erstens ein Wiederauffinden der Gerätschaften oder (falls der Sportler verschüttet, aber das Gerät an der Oberfläche verbleibt) eine Suche des Verschütteten erleichtert.The system can be combined with a very easy unwinding cord in the case of triggering, which firstly makes it easier to find the equipment or (if the athlete spills but the equipment remains on the surface) to facilitate a search for the victim.
Die vorgelegte Erfindung richtet ihren Fokus in erster Linie auf die Erhöhung der Sicherheit von alpinen Skifahrern, Tourengehern, Varianten- und Snowboardfahrern, die sich abseits gesicherter Pisten bewegen und daher einem erhöhten Risiko ausgesetzt sind, bei einem potentiellen Lawinenunfall zu verunglücken.The present invention focuses primarily on increasing the safety of alpine skiers, touring skiers, variant skiers and snowboarders, who move away from secured pistes and are therefore at an increased risk of being involved in a potential avalanche accident.
Die vorgelegte Erfindung offenbart ein zuverlässiges, relativ einfach und kostengünstig zu realisierendes, elektrisch/elektronisch ansteuerbares, zu auf dem Markt befindlichen Sportgerätekomponenten kompatibles, pyrotechnisches Notauslösesystem insbesondere für Ski, Skistock und Snowboard.The present invention discloses a reliable, relatively easy and inexpensive to implement, electrically / electronically controllable, on the market Sports equipment components compatible pyrotechnic emergency release system especially for skis, ski poles and snowboards.
Die Erfindung betrifft also ein elektrisch ansteuerbares Notauslösesystem, welches insbesondere in Lawinensituationen eine pyrotechnisch ausgeführte Trennung von Skischuh und Ski bzw. von Hand und Skistock vermittelt.The invention thus relates to an electrically triggerable emergency release system, which, in particular in avalanche situations, mediates a pyrotechnically executed separation of ski boot and ski or of hand and ski pole.
Die Erfindung weist ferner folgende vorzugsweise realisierte Merkmale auf:
- eine sehr kompakte, leichtgewichtige und kostengünstige Lösung,
- eine Erhöhung der Sicherheit von Skifahrer und Snowboarder, welche sich abseits der gesicherten Piste bewegen (z. B. Variantenfahrer, Freerider, Tourenskifahrer etc). bei Lawinenunfällen

- die pyrotechnische Auslösevorrichtung für die Tourenskibindungen und für das Snowboard kann die Trennung des Fangriemens bei der Auslösung einschließen,
- es kann das pyrotechnische Notauslösesystem mit den auf dem Markt befindlichen ABS- Lawinen-Airbags kombiniert werden, die ein Beispiel eines erfindungsgemäß vorgesehenen weiteren Rettungssystems bilden (bei diesen Systemen - http://www.abs-lawinenairbag.de - wird durch Zug am Auslösegriff elektrisch angesteuert eine Druckluftpatrone geöffnet und ein Ballonsystem aufgeblasen. Das für diesen Auslösevorgang verwendete Auslösesignal könnte gleichzeitig die erfindungsgemäße Notauslösung triggern),
- es kann ggf. nur einmal elektronisch ausgelöst werden, da danach die Explosions- oder Treibladung erneuert werden muss. Die Funktionsfähigkeit der Skibindung ist nach erfolgter Notauslösung manuell leicht wiederherstellbar, und der Fangriemen leicht einsetzbar. Der Skistock und die Snowboard- Bindung sind manuell leicht wieder zusammensetzbar.
- die pyrotechnische Treibladung (z. B. Pille) und die damit verbundene Sprengkraft kann klein gehalten werden, um Sicherheitsstandards gerecht zu werden. Die vorzugsweise geringe Sprengkraft kann unter Verwendung von Dichtungen und/oder einer geringen Masse (geringe Trägheit) der zu bewegenden Teile (Kolben, Zylinder) effektiv ausgenutzt werden, sodass die im Auslösefall zu bewegenden Teile schnell beschleunigt werden können, wodurch ein außerordentlich schnelles Auslösesystem bereitgestellt wird. Vorzugsweise arbeitet das erfindungsgemäße System so schnell, dass der Auslösemechanismus innerhalb von ca. 1 ms geöffnet werden kann.

- it may possibly be triggered only once electronically, since then the explosion or propellant charge must be renewed. The functionality of the ski binding is manually easily recovered after emergency release, and the lanyard easy to use. The ski pole and the snowboard binding can be reassembled manually.
- the pyrotechnic propellant charge (eg pill) and the associated explosive force can be kept small to meet safety standards.

Es werden nachfolgende insbesondere und beispielhaft zwei technische Ausführungsformen angegeben, die kompatibel zu vorhandenen Bindungssystemen sind und daher eine Zurüstung ohne maßgebliche Veränderung der bestehenden Sicherheitsbindung erlauben. Im Auslösefall erfolgt bei beiden Varianten die Entriegelung des abzutrennenden Teils dadurch, dass das Widerlager einer Einstell- bzw. Einrastfeder durch einen beweglichen Zylinder, welcher durch eine pyrotechnische Treibladung antreibbar ist, gelöst wird. Dadurch wird die Einstell- bzw. Einrastfeder entspannt, und die Verriegelung aufgehoben. Durch den bewegten Zylinder wird ein Federblech verformt, mit dem das Widerlager gehalten ist. Bei der ersten Ausführungsform ist das Federblech konisch, und die Einstell- bzw. Einrastfeder wird in der Bewegungsrichtung des bewegten Zylinders entspannt. Bei der zweiten Ausführungsform ist das Federblech eben, und die Einstellfeder wird entgegen der Bewegungsrichtung des bewegten Zylinders entspannt.The following, in particular and by way of example, two technical embodiments are given, which are compatible with existing binding systems and therefore allow equipment without significantly changing the existing security binding. When triggered in both variants, the unlocking of the part to be separated takes place in that the abutment of an adjusting or locking spring by a movable cylinder, which is driven by a pyrotechnic propellant charge, is released. As a result, the adjusting or locking spring is relaxed, and the Lock unlocked. Through the moving cylinder, a spring plate is deformed, with which the abutment is held. In the first embodiment, the spring plate is conical, and the adjusting or latching spring is relaxed in the direction of movement of the moving cylinder. In the second embodiment, the spring plate is flat, and the adjusting spring is relaxed against the direction of movement of the moving cylinder.

Eine mögliche Position der pyrotechnischen Auslösevorrichtung in einer Snowboard-Bindung (auch hier kann sie gemäß beiden Ausführungsformen ausgeführt werden) ist in

Im Auslösefall ist die pyrotechnische Pille 16 zündbar. Die Pille 16 befindet sich in einer dünnen Metallhülse 17, die von einem O-Ring 18 gedichtet ist. Die Metallhülse 17 und der O-Ring 18 sind mit einer Halterung 29 durch die Schraube 28 fixiert. Durch das entstehende Treibgas ist der Zylinder 19 axial nach außen bewegbar, das gekrümmte Ende des Federblechs 10 radial nach innen verschiebbar und so vom Führungsrohr 11 entkoppelbar, das Widerlager 6 axial nach außen verschiebbar, und die Einstellfeder 5 entspannbar. Mit anderen Worten, das entstehende Treibgas kann bewirken, dass die Feder bzw. das Federblech 10 verformt wird, wodurch eine Entkopplung stattfinden kann. Vorzugsweise ist die pyrotechnische Pille 16 möglichst klein, wodurch die Sprengwirkung entsprechend gering ausfällt. Die Erfüllung von Sicherheitsstandards kann dementsprechend leicht erreicht werden. Um die bevorzugte geringe Sprengkraft effektiv auszunutzen ist es besonders vorteilhaft, wenn Dichtungen (z. B. O-Ring 18) vorhanden sind, die ein unkontrolliertes Entweichen des Treibgases reduzieren bzw. verhindern, sodass das Treibgas den Zylinder 19 effektiv bewegen kann. Zudem ist es bevorzugt, wenn die Masse des Zylinders 19 gering ist (geringe Trägheit), wodurch der Zylinder effektiv und vorzugsweise schnell beschleunigt werden kann, sodass ein außerordentlich schnelles Auslösesystem bereitgestellt wird. So beträgt beispielsweise die Gesamtzeit für einen Pillenangetriebenen Hub eines Zylinders 19 von 1,7 cm ca. 1,2 ms. Diese Zeit setzt sich zusammen aus der Brenndauer der Pille 16 (Zeit bis die Druckwelle entsteht) von 0,7ms und aus der Zeit für die Verschiebung des Zylinders 19 von 0,5ms.When triggered, the
