Abstract

Bei einer selbsttätigen unter Einwirken von Wasser auslösbarer Aufblasvorrichtung für schwimmfähige Rettungsgeräte, die einen Schlagbolzen 15 mit einer Spitze 16 zum Durchstoßen der Verschlußmembran 14 einer Druckgaspatrone 12 aufweist, treibt eine pyrotechnische Ladung 19 durch Zünden einen Stempel 22 zur Bewegung des Schlagbolzens 15 gegen die Kraft einer Feder 23 in Richtung auf die Verschlußmembran 14. Die Spitze 16 des Schlagbolzens 15 sowie die Verschlußmembran 14 bestehen aus elektrisch leitfähigen Werkstoffen. In der Bereitschaftsstellung liegt die Spitze 16 des Schlagbolzens 15 an der Verschlußmembran 14 an und stehen die Verschlußmembran 14 der Druckgaspatrone 12 einerseits sowie die Spitze 16 des Schlagbolzens 15 andererseits elektrisch mit einer Anzeigevorrichtung in Verbindung stehen, um das Fehlen oder Vorhandensein einer Druckgaspatrone 12 mit einer intakten Verschlußmembran 14 anzuzeigen.

Figure 00000001
In an automatic inflatable device under the action of water for buoyant rescue devices, which has a firing pin 15 with a tip 16 for piercing the sealing membrane 14 of a compressed gas cartridge 12, a pyrotechnic charge 19 drives a plunger 22 to move the firing pin 15 against the force of one Spring 23 in the direction of the closure membrane 14. The tip 16 of the firing pin 15 and the closure membrane 14 consist of electrically conductive materials. In the ready position, the tip 16 of the firing pin 15 bears against the sealing membrane 14 and the sealing membrane 14 of the compressed gas cartridge 12 on the one hand and the tip 16 of the firing pin 15 on the other hand are electrically connected to a display device to indicate the absence or presence of a compressed gas cartridge 12 indicate intact closure membrane 14.
