Claims (8)

1. Federelement aus elastischem Werkstoff, insbesondere aus Kunststoff (z. B. Polyurethan), zur Aufnahme kinetischer Energie, gebildet aus einem Rohrstück (1) und einer damit fest verbundenen Grundplatte (2), wobei das Rohrstück (2) eine Wanddicke entsprechend einem Verhältnis Außendurch­ messer (Da) zu Innendurchmesser (Di) von < 2 und eine Bauhöhe (He) im Bereich des 0,7- bis 1,3-fachen des Außendurchmessers (Da) aufweist, so dass bei einer Einfederung in einer Größenordnung von 35% der ursprüngli­ chen Bauhöhe am offenen Ende des Rohrstückes (1) eine Umstülpung der kraftbeaufschlagten Fläche stattfindet.1. Spring element made of elastic material, in particular made of plastic (e.g. polyurethane), for absorbing kinetic energy, formed from a pipe section ( 1 ) and a base plate ( 2 ) firmly connected thereto, the pipe section ( 2 ) corresponding to a wall thickness Ratio of outside diameter (Da) to inside diameter (Di) of <2 and a height (He) in the range of 0.7 to 1.3 times the outside diameter (Da), so that with a deflection in the order of 35 % of the original overall height at the open end of the pipe section ( 1 ) an inversion of the force-applied surface takes place. 2. Federelement nach Anspruch 1, dadurch gekennzeichnet, dass im Übergangsbereich von Rohrstück (1) und Grundplatte (2) eine äußere, um­ laufende Nut (3) angeordnet ist, die eine spannungsmäßig günstigere Verfor­ mung des Rohrstückes (1) bewirkt.2. Spring element according to claim 1, characterized in that in the transition region of the pipe section ( 1 ) and base plate ( 2 ) an outer, running groove ( 3 ) is arranged, which causes a more favorable strain Verfor formation of the pipe section ( 1 ). 3. Federelement nach Anspruch 1 oder 2, dadurch gekennzeichnet, dass im Zentrum der Grundplatte (2) eine Bohrung vorgesehen ist, die mit Hilfe ei­ nes Verbindungsmittels (Schraube 4) ein horizontales oder vertikales Befesti­ gen des Federelementes an einem vor Überlastung zu schützenden Bauteil ermöglicht.3. Spring element according to claim 1 or 2, characterized in that in the center of the base plate ( 2 ) a bore is provided which, with the aid of egg nes connecting means (screw 4 ), a horizontal or vertical fastening of the spring element to a component to be protected against overload enables. 4. Federelement nach einem der Ansprüche 1 bis 3, gekennzeichnet durch eine innere Führungshülse (5) zum Führen des Rohrstückes (1), wobei der Außendurchmesser der Führungshülse (5) gleich dem Innendurchmesser (Di) des Rohrstückes (1) ist und die Höhe (Hf) der Führungsfläche mindestens das 0,2-fache der Bauhöhe (He) des Rohrstückes (1) beträgt.4. Spring element according to one of claims 1 to 3, characterized by an inner guide sleeve ( 5 ) for guiding the pipe section ( 1 ), wherein the outer diameter of the guide sleeve ( 5 ) is equal to the inner diameter (Di) of the pipe section ( 1 ) and the height (Hf) of the guide surface is at least 0.2 times the overall height (He) of the pipe section ( 1 ). 5. Federelement nach Anspruch 4, dadurch gekennzeichnet, dass die Führungshülse (5) mit einer Abschrägung (6) oder einer Abstufung ausge­ stattet ist, die ein leichteres Vorbeiführen der umgestülpten kraftbeaufschlag­ ten Fläche des Rohrstückes (1) während der weiteren Belastung erbringt. 5. Spring element according to claim 4, characterized in that the guide sleeve ( 5 ) is equipped with a bevel ( 6 ) or a gradation, which provides easier passage of the inverted force applied surface of the pipe section ( 1 ) during the further loading. 6. Federelement nach Anspruch 4 oder 5, dadurch gekennzeichnet, dass die Führungshülse (6) eine quer zur Kraftrichtung angeordnete Fläche auf­ weist, über die bei Berührung mit der krafteinleitenden Fläche des Rohrstüc­ kes (1) eine Weiterleitung der Kräfte auf die Grundplatte (2) erfolgt, wodurch eine Steigerung der Arbeitsaufnahme vor dem Ende des Hubes erzielt wird.6. Spring element according to claim 4 or 5, characterized in that the guide sleeve ( 6 ) has a surface arranged transversely to the direction of force, via which, when in contact with the force-introducing surface of the tubular piece ( 1 ), the forces are transmitted to the base plate ( 2 ) takes place, whereby an increase in work intake is achieved before the end of the stroke. 7. Federelement nach einem der Ansprüche 1 bis 6, gekennzeichnet durch eine innere Hubbegrenzung zum Schutz vor Überlastung, die vorzugs­ weise durch eine quer zur Kraftrichtung angeordnete Fläche des Verbin­ dungsmittels (Schraube 4) gebildet ist.7. Spring element according to one of claims 1 to 6, characterized by an inner stroke limitation for protection against overload, the preference, by a transverse to the direction of force surface of the connec tion means (screw 4 ) is formed. 8. Federelement nach Anspruch 1, geführt auf einer Stange mit einer obe­ ren Führung dergestalt, das eine Platte mit konischen Seitenflächen an der Krafteinleitungsseite in das Rohrstück (1) hineinragt, wobei der maximale Durchmesser der Platte mit dem Innendurchmesser (Di) des Rohrstückes (1) übereinstimmt.8. Spring element according to claim 1, guided on a rod with an obe ren guide such that a plate with conical side surfaces on the force introduction side protrudes into the pipe section ( 1 ), the maximum diameter of the plate with the inner diameter (Di) of the pipe section ( 1 ) matches.
