Abstract

Es wird ein gedämpfter pyrotechnischer Aktuator angegeben, der ein Aktuatorgehäuse (2) aufweist, in dem wenigstens ein axial beweglicher Kolben (3) mit daran angeordneter Kolbenstange (4) angeordnet ist. Die Kolbenstange ragt an ihrem dem Kolben gegenüberliegenden Ende aus dem Aktuatorgehäuse heraus. Der Kolben ist mit einer innerhalb des Aktuatorgehäuses angeordneten druckgaserzeugenden pyrotechnischen Treibladung (8) verschiebbar. Der Kolben ist mittels eines Fixiersystems (6) bis zu einem vorbestimmten Druck in seiner Grundstellung gehalten. Der Innenraum des Aktuatorgehäuses ist auf der der Druckkammer gegenüberliegenden Seite des Kolbens wenigstens teilweise mit einer Flüssigkeit (7) gefüllt. Die Flüssigkeit ist mittels eines Verschlusses (5) in dem Aktuatorgehäuse gehalten und der Verschluss ermöglicht beim Überschreiten des vorbestimmten Druckes ein Ausströmen der Flüssigkeit.

The invention relates to a damped pyrotechnic actuator which has an actuator housing (2) in which at least one axially movable piston (3) with piston rod (4) arranged thereon is arranged. The piston rod protrudes from the actuator housing at its end opposite the piston. The piston is displaceable with a pressure-gas-generating pyrotechnic propellant charge (8) arranged inside the actuator housing. The piston is held by a fixing system (6) to a predetermined pressure in its normal position. The interior of the actuator housing is at least partially filled with a liquid (7) on the side of the piston opposite the pressure chamber. The liquid is held in the actuator housing by means of a closure (5) and the closure allows the liquid to flow out when the predetermined pressure is exceeded.
