Abstract

Die Erfindung betrifft eine Vorrichtung (1) zur Energieabsorption mit mindestens zwei voneinander durch Abstandsteile (6) beabstandeten Platten (2, 3), wobei die erste Platte (2) derart angeordnet ist, dass die mit der zu absorbierenden Energie verbundene Kraft zunächst auf diese Platte (2) wirkt.The invention relates to a device (1) for energy absorption with at least two spaced apart by spacers (6) spaced plates (2, 3), wherein the first plate (2) is arranged such that the force associated with the energy to be absorbed first on this Plate (2) acts.

Um zu erreichen, dass die Vorrichtung (1) ein relativ geringes Gewicht aufweist und trotzdem auf einfache Weise eine hohe Energieabsorption bewirkt, schlägt die Erfindung vor, den Zwischenraum zwischen den beiden voneinander beabstandeten Platten (2, 3) mit einem Füllmaterial (13), wie einer Flüssigkeit mit entsprechend hoher Viskosität, einem Gel, einem Kunststoff- oder Metallschaum oder einem Granulat, auszufüllen, welches beim Zusammendrücken der beiden Platten (2, 3) durch mindestens eine Ausströmöffnung (10, 11) mit definiertem Strömungsquerschnitt entweichen kann. Durch den Strömungswiderstand des Füllmaterials (13) im Bereich des definierten Strömungsquerschnittes der Ausströmöffnung (10, 11) erfolgt dann die gewünschte Energieabsorption.

In order to achieve that the device (1) has a relatively low weight and yet causes a simple way of high energy absorption, the invention proposes that the space between the two spaced-apart plates (2, 3) with a filling material (13), as a liquid with a correspondingly high viscosity, a gel, a plastic or metal foam or granules to fill, which during the compression of the two plates (2, 3) by at least one outflow opening (10, 11) can escape with a defined flow cross-section. By the flow resistance of the filling material (13) in the region of the defined flow cross-section of the outflow opening (10, 11) then the desired energy absorption takes place.
