Abstract
The bag forms a safety device for the crewman, having a body inflated via a valve (2) and divided into sections. This is installed in the belt mechanism or a seat in the glider. The valve is situated at the front of the seat and below the seat surface. It is held in position by a frame (1), so that the bag is inflated only by the slipstream. The valve can be hose-shaped and of material distorted by pressure inside the bag, being clamped to the frame at its inlet (3). The frame (3) can be aerodynamically shaped, so as to reduce resistance to air flow.
Description
Gegenstand der Erfindung ist ein aufblasbarer Luftsack als Sicherheitsvorrichtung für Benützer von Gleitfluggeräten nach dem Oberbegriff des unabhängigen Patentanspruches.
Durch ungünstige Windverhältnisse, durch eine falsch kalkulierte Landung oder als Folge einer gewagten Flugfigur kann sich der Pilot plötzlich in einer Situation befinden, die, ohne geeignete Sicherheitsvorrichtung, zu einem heftigen Aufschlag am Boden führen kann. In grossen Höhen bietet ein Notschirm den besten Ausweg. In geringer Flughöhe bleibt dem Notschirm zuwenig Zeit, um sich zu entfalten. Da der Pilot sitzend am Gleitschirm hängt, fällt er bei einem Absturz häufig auf Becken und Rücken.
Aus W091/08 949 (Wenger) ist ein Gurtzeug für Gleitschirme bekannt, welches als Sicherheitsvorrichtung bei unsanften Landungen dient. Sie umfasst ein als Sitz ausgestaltetes Aufprallkissen. Dieser Sitz weist ein Sitzkissen und ein damit gekoppeltes Rückenkissen auf. Diese Kissen weisen stossmindernde Absorptionskörper in Form von aufblasbaren matratzenartigen Luftkissen mit mehreren Kammern auf. Rückenkissen und Sitzkissen werden vor dem Start über je ein Ventil aufgeblasen.
Aufgabe der Erfindung ist es, eine als Sitz ausgestaltete Sicherheitsvorrichtung zu schaffen, welche beim Flug mit dem Gleitschirm vom Fahrtwind selbst aufgeblasen wird.
Um Fehlreaktionen des Piloten vorzubeugen und um Zeitverluste durch die \ffnungszeit des Sicherheitssystems zu vermeiden, muss die Vorrichtung so geschaffen sein, dass sie bei jedem Flug vor der Landevorbereitung eingesetzt wird.
Die Aufgabe wird wie in Patentanspruch 1 angegeben gelöst.
Der Pilot trägt den eingepackten Luftsack an der Aussenseite des Sitzes des Gleitfluggerätes (Fig. 2). Durch Zug an einem Auslösegriff 9 wird die Packvorrichtung 9 entfernt oder geöffnet und das Ventil 2 in den Fahrtwind gestellt. Der Luftsackkörper 1 wird sitzförmig am Piloten aufgepumpt. Nach der Landung wird die Luft über eine Entleerungsvorrichtung 7 abgelassen. Der Luftsack kann mit dem Sitz des Gleitfluggerätes eingepackt werden und ist für den nächsten Einsatz bereit.

Der Luftsack kann gemäss Anspruch 8 auf verschiedene Weise getragen werden. Fix oder abnehmbar an den Sitz angebaut, oder mit eigenem Gurtzeug, falls er mit einem beliebigen Sitz verwendet werden soll.
Der Pilot startet mit verpacktem Luftsack (Fig. 2). Sobald er in Bodennähe kommt, und ein Notschirm nicht mehr eingesetzt werden kann, wird die Auslösevorrichtung durch Zug am Auslösegriff 8 betätigt. Die Packvorrichtung 9, welche den Luftsack umhüllt, wird über eine Auslöseleine 10 entfernt oder geöffnet. Das Ventil 2 stellt sich durch sein Gewicht von selber in die richtige Position. Die aerodynamische Form des Ventilrahmens 3 verringert den Luftwiderstand des Ventils 2.
Das Ventil 2 weist einen Ventilrahmen 3 auf. Es ist schlauchförmig und besteht aus leicht verformbarem Gewebe. Die Luft wird durch das Ventil 2 in den Luftsackkörperinnenraum geleitet. Der Fahrtwind erzeugt im Luftsackkörper 1, relativ zur Umgebung, einen erhöhten Druck. Reisst der Fahrtwind ab, wird das verformbare Ventil 2 vom Überdruck im Luftsackkörperinnern zusammengepresst. d.h. das Ventil 2 schliesst, die Luft kann dem Luftsackkörper 1 nicht entweichen. Der gleiche Effekt erfolgt bei einem Fall auf den Luftsack.
Das Ventil 2 ist am hinteren Ende des Ventilschlauchs über zwei Ventilpositionierer 6 an der Ober- und Unterwandung des Innenraums des Luftsackkörpers 1 befestigt. Die Ventilpositionierer 6 dienen der Positionierung des Ventils 2 bei der Entfaltung des Luftsacks.
Der Luftsackkörperinnenraum ist durch Zwischenwände 4 in Teilräume aufgeteilt. Die Teilräume sind durch Zwischenwandöffnungen 5 miteinander verbunden. Die Unterteilung soll bei einem Aufprall das plötzliche Ausweichen der Luft in weniger belasteten Raum verzögern. Die Entleerungsvorrichtung 7 dient dem Luftablass nach der Landung. Sie kann in Form von einem verschraubbaren Verschluss aus leichtem Material oder mit einem Reissverschluss realisiert werden. Nach der Landung wird der Luftsackkörper 1 über eine Entleerungsvorrichtung 7 entleert, gefaltet, der Ventilrahmen 3 zurückgeklappt und mit der Packvorrichtung 9 eingepackt.
The invention relates to an inflatable airbag as a safety device for users of gliding aircraft according to the preamble of the independent claim.
Due to unfavorable wind conditions, an incorrectly calculated landing or as a result of a daring flight figure, the pilot can suddenly find himself in a situation that, without a suitable safety device, can lead to a violent impact on the ground. At great heights, an emergency parachute is the best way out. At low altitude, the emergency parachute does not have enough time to develop. Since the pilot is sitting on the paraglider, he often falls on the pelvis and back in the event of a crash.
From W091 / 08 949 (Wenger) a harness for paragliders is known, which serves as a safety device for rough landings. It comprises an impact cushion designed as a seat. This seat has a seat cushion and a back cushion coupled to it. These pillows have shock-absorbing absorbent bodies in the form of inflatable mattress-like air pillows with several chambers. Back cushions and seat cushions are inflated via a valve each before starting.
The object of the invention is to provide a safety device designed as a seat, which is inflated by the wind itself when flying with the paraglider.
In order to prevent the pilot from reacting incorrectly and to avoid wasting time due to the opening time of the safety system, the device must be designed in such a way that it is used on every flight before the preparation for landing.
The object is achieved as indicated in claim 1.
The pilot carries the packed airbag on the outside of the seat of the glider (Fig. 2). By pulling a release handle 9, the packing device 9 is removed or opened and the valve 2 is placed in the airstream. The airbag body 1 is inflated in a seat shape on the pilot. After landing, the air is released via an evacuation device 7. The airbag can be packed with the seat of the glider and is ready for the next use.

The airbag can be carried in different ways according to claim 8. Fixed or detachable to the seat, or with your own harness if you want to use it with any seat.
The pilot takes off with the airbag packed (Fig. 2). As soon as he comes close to the ground and an emergency parachute can no longer be used, the release device is actuated by pulling the release handle 8. The packing device 9, which envelops the airbag, is removed or opened via a release line 10. Due to its weight, the valve 2 automatically moves into the correct position. The aerodynamic shape of the valve frame 3 reduces the air resistance of the valve 2.
The valve 2 has a valve frame 3. It is tubular and consists of easily deformable fabric. The air is passed through valve 2 into the interior of the airbag body. The airstream creates an increased pressure in the airbag body 1, relative to the surroundings. If the airstream breaks off, the deformable valve 2 is compressed by the excess pressure in the interior of the airbag body. i.e. the valve 2 closes, the air cannot escape from the airbag body 1. The same effect occurs in the event of a fall on the airbag.
The valve 2 is fastened at the rear end of the valve hose via two valve positioners 6 to the upper and lower walls of the interior of the airbag body 1. The valve positioners 6 are used to position the valve 2 when the airbag is deployed.
The interior of the airbag body is divided into partitions by partitions 4. The subspaces are connected to one another by partition openings 5. In the event of an impact, the subdivision is intended to delay the sudden escape of air into less polluted space. The emptying device 7 serves to deflate the air after landing. It can be realized in the form of a screwable fastener made of light material or with a zipper. After landing, the airbag body 1 is emptied via an emptying device 7, folded, the valve frame 3 is folded back and packed with the packing device 9.
