Abstract
Description
Mechanische Sicherheitsgurtstrammer haben die Aufgabe, in der Frühphase eines Aufpralles Gurtlose aus dem System mittels Federspannung zu nehmen, um damit die Verletzungsschwere zu mindern.Mechanical seat belt tensioners have that Task, in the early phase of an impact Strapless from the system by means of spring tension to increase the severity of the injury reduce.
Alle Systeme arbeiten derart, daß eine Feder kraft durch Verzögerung ausgelöst, den Sicherheitsgurt verspannt, bzw. Gurtlose aus dem System nimmt.All systems work in such a way that a spring force triggered by delay, the Seat belt tensioned or strapless off the system.
Die Millisekunden später nach vorn fliegende Person bringt eine höhere Belastung auf das Gurtschloß, als eine Feder aufbringen kann. Ein Sperrmechanismus verhindert das Zurück ziehen der Feder.The milliseconds later flying forward Person puts a higher burden on that Buckle as a spring can apply. A locking mechanism prevents the back pull the feather.
Zweck der Erfindung ist ein einfacher und wirkungsvoller Sperrmechanismus in der Gurtschloß-/Feder-Seilführung integriert. The purpose of the invention is simple and effective locking mechanism in the Belt buckle / spring rope guide integrated.
Bei mechanischen Gurtstrammern wird, wie technisch üblich, in der Frühphase des Unfallgeschehens das Gurtschloß mittels Federkräften nach unten gerissen. Hierdurch werden Gurtlose aus dem System genommen und damit die Unfallschwere gemindert.With mechanical belt tensioners, how technical usual in the early stages of the accident Belt buckle torn down by spring force. This will remove the strapless from the system and thus reduced the severity of the accident.
Eine mechanische Feder wird hierbei durch Verzögerung ausgelöst und zieht an einem Seil das Gurtschloß nach unten.A mechanical spring is hereby delayed triggered and pulls the belt buckle on a rope below.
Millisekunden später fliegt die, mit mehr Trägheit belastete Person, gegen die Feder und will sie wieder spannen. Ein Sperrmechanismus muß dies verhindern.Milliseconds later, it flies with more inertia burdened person, against the spring and wants it tension again. A locking mechanism must do this prevent.
Erfindungsgemäß sind Strammfeder und Gurtschloß mit Seilen verbunden. Die Seile werden in einem Rohr geführt. Das Rohr ist den Gegebenheiten des Sitzes und der Gurtschloßlage in der Form angepaßt, d.h. entsprechend räumlich angewinkelt.According to the invention, the spring and belt buckle are included Ropes connected. The ropes are in a tube guided. The tube is the conditions of the seat and adapted to the shape of the buckle position, i.e. accordingly angled spatially.
Das Rohr hat im Strammbereich einen zylindrischen Durchmesser und ist auf Strammlänge (ca. 100 mm) gerade. Das Seil der Strammfeder ist mit einem zylindrischen Stahlkolben kraftschlüssig verbunden. Die sicherheitsgurtschloßseitigen beiden Seile sind mit diesem zylindrischen Stahlkolben ebenso kraftschlüssig verbunden. In einem Abstand ist ein zweiter in Richtung des ersten Kolbens ab geschrägter Kolben ebenfalls mit den Seilen des Sicherheitsgurtschlosses kraftschlüssig verbunden.The tube has a cylindrical shape in the tightening area Diameter and is at string length (approx. 100 mm) just. The rope of the tension spring is with one cylindrical steel piston non-positively connected. The two ropes on the seat belt buckle side are the same with this cylindrical steel piston non-positively connected. At a distance is one second towards the first piston inclined piston also with the ropes of the Seat belt buckle non-positively connected.
Zwischen beiden Kolben ist ein loser "Schneidring" kippbar gelagert mit Löchern für den Seildurchgang des Gurtschlosses.There is a loose "cutting ring" between the two pistons tiltable with holes for the rope passage of the buckle.
Beim Bewegen des Systems durch die Zugfeder wird der "Schneidring" durch den abgeschrägten Zylinder derart gekippt, daß er nicht sperrt.When moving the system through the tension spring the "cutting ring" through the beveled cylinder tilted so that it does not lock.
Beim Bewegen des Systems durch das Sicherheits gurtschloß (die kinetische Energie der gesicherten Person ist stärker als die Feder) kippt der Zylinder mit geradem Kopfende den Schneidring in Funktionsposition, d.h. er verkeilt sich mit dem Rohr. When moving the system through security buckle (the kinetic energy of the secured Person is stronger than the spring) tilts Cylinder with straight head end the cutting ring in Functional position, i.e. he wedges with the Pipe.
Ein Ausführungsbeispiel ist in der Zeichnung dargestellt und im folgenden näher beschrieben.An embodiment is in the drawing shown and described in more detail below.
Erfindungsgemäß besteht der Sperrmechanismus aus einem in der Zeichnung teils aufgebrochenen Führungsrohr 1. Das Seil 2 einer Strammfeder 3 ist mit einem zylindrischen Stahlkolben 4 kraft schlüssig verbunden. Die sicherheitsgurtschloß seitigen beiden Seile 6 sind mit diesem zylindrischen Stahlkolben 4 ebenso kraftschlüssig verbunden. In einem Abstand ist ein zweiter Kolben 7 in Richtung des ersten abgeschrägt und ebenfalls mit den Seilen 6 des Gurtschlosses 5 kraftschlüssig verbunden.According to the invention, the locking mechanism consists of a guide tube 1 which is partially broken open in the drawing. The rope 2 of a tension spring 3 is positively connected to a cylindrical steel piston 4 . The seat belt buckle-side two ropes 6 are also non-positively connected to this cylindrical steel piston 4 . At a distance, a second piston 7 is chamfered in the direction of the first and is also non-positively connected to the ropes 6 of the belt buckle 5 .
Zwischen beiden Kolben ist ein Schneidring 8 kippbar gelagert mit Löchern 9 für den Seil durchgang 6 des Gurtschlosses 5.A cutting ring 8 is tiltably supported between the two pistons with holes 9 for the cable passage 6 of the belt buckle 5 .
Beim Bewegen des Systems durch die Zugfeder 3 wird der Schneidring 8 durch den abgeschrägten Zylinder 7 derart gekippt, daß er nicht sperrt. When the system is moved by the tension spring 3 , the cutting ring 8 is tilted by the beveled cylinder 7 in such a way that it does not lock.
Beim Bewegen des Systems durch das Sicherheits gurtschloß 5 beziehungsweise darauf einwirkende Zugkräfte kippt der Zylinder 4 mit seinem geraden Kopfende den Schneidring 8 in Funktions position, d.h. er verklemmt sich mit dem Rohr.When moving the system through the safety belt buckle 5 or tensile forces acting on it, the cylinder 4 tilts the cutting ring 8 into its functional position with its straight head end, ie it jams with the tube.
