Abstract
Description
Die Erfindung betrifft einen Schwenkträger nach dem Oberbe griff des Patentanspruchs 1.The invention relates to a swivel bracket according to the Oberbe handle of claim 1.
Bei einem bekannten Schwenkträger dieser Art (DE 195 44 425 A1) ist ein Verbindungsbereich zwischen den Anlenkachsen als Blechformteil gefertigt. Der Verbindungsbereich ist durch Ausnehmungen oder quer zur Kraftrichtung verlaufende Sicken in seiner Tragfestigkeit gezielt geschwächt. Er kann außerdem in Belastungsrichtung gekrümmt ausgebildet sein. Dadurch knickt der Schwenkträger bei übermäßiger Druckbela stung aus. Bei seiner Verformung absorbiert der Schwenkträ ger Energie und verringert dadurch im Crashfall die auf ei nen Sitzbenutzer wirkende Belastung. Der bekannte Schwenk träger hat den Nachteil, daß nach erfolgter Einleitung des Knickvorgangs die Steifigkeit des Schwenkträgers rapide ab nimmt, so daß er bei Überschreiten der Grenzbelastung schlagartig zusammenbricht. Bei Zugbelastung hat der Schwenkräger nur ein geringes Energieaufnahmepotential.In a known swivel bracket of this type (DE 195 44 425 A1) is a connection area between the articulation axes manufactured as a sheet metal part. The connection area is through recesses or transverse to the direction of force The weakening of the beads is deliberately weakened. He can also be curved in the direction of loading. This causes the swivel bracket to kink in the event of excessive pressure equipment. When it is deformed, the swivel beam absorbs energy and thereby reduces the amount of energy in the event of a crash strain acting on the seat user. The well-known pan carrier has the disadvantage that after the initiation of the Kinking the rigidity of the swivel bracket rapidly takes so that when the limit load is exceeded suddenly collapses. With tensile load the Swivel bracket only has a low energy absorption potential.
Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, einen Schwenkträger der als bekannt vorausgesetzten Art so auszubilden, daß er bei Zug- und Druckbelastung einen dosierten Energieabbau über einen vor gegebenen Weg ermöglicht.The invention is based on this prior art based on the task of a swivel bracket known as required type so that he can train and Pressure load a metered energy reduction via a given path.
Die Lösung dieser Aufgabe erfolgt mit den Merkmalen des Pa tentanspruchs 1.This problem is solved with the characteristics of Pa claim 1.
Bei dem erfindungsgemäßen Schwenkträger sind ein vollstän diges Ausknicken unter Druck oder ein Abreißen bei Zug in einen sehr hohen Belastungsbereich verschoben. Der jeweils verformbare Teil des Schwenkträgers wird nur in einem Be reich verformt, bei dem seine Steifigkeit oder Festigkeit nicht wesentlich absinkt. Die Lageänderung des von dem Schwenkträger gestützten Sitzteils hält sich dabei in ver tretbaren Grenzen.In the swivel bracket according to the invention are complete buckling under pressure or tearing when pulling in shifted a very high load range. The each deformable part of the swivel bracket is only in one loading richly deformed, giving its rigidity or strength does not sink significantly. The change in location of that Swivel-supported seat part stays in ver reasonable limits.
Bevorzugte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.Preferred embodiments of the invention result from the subclaims.
Die Verformung und die Energieaufnahme können bei einer be sonders bevorzugten Ausführungsform durch die Zahl der Schichten vergrößert und verstetigt werden. Durch die Wahl von Beschaffenheit und Form der Schichten kann das Verfor mungsverhalten vergleichsweise genau vorausbestimmt werden. Ein Reibschluß der Schichten im Bereich ihrer Anlenkstellen verzehrt bei deren gegenseitiger Verschiebung zusätzlich kinetische Energie durch Reibung.The deformation and the energy consumption can be with a particularly preferred embodiment by the number of Layers are enlarged and stabilized. By choice the condition and shape of the layers can be deformed behavior can be predicted comparatively precisely. A frictional engagement of the layers in the area of their articulation points consumes in addition to their mutual displacement kinetic energy through friction.
Nachstehend wird eine bevorzugte Ausführungsform der Erfin dung anhand der Zeichnungen näher beschrieben. Es zeigen: The following is a preferred embodiment of the invention dung described with reference to the drawings. Show it:

Fig. 2 - einen Längsschnitt durch einen Lenker gemäß Fig. 1 im Ausgangszustand; FIG. 2 shows a longitudinal section through a handlebar according to FIG. 1 in the initial state;
Fig. 3 - einen Längsschnitt durch den Lenker gemäß Fig. 2 mit einer ersten ausgeknickten Schicht; Figure 3 - shows a longitudinal section through the handlebar of Figure 2 with a first extended buckled layer..;
Fig. 4 - einen Längsschnitt durch den Lenker gemäß Fig. 2 in seinem verformten Endzustand. Fig. 4 - a longitudinal section through the handlebar according to FIG. 2 in its deformed final state.
Ein Kraftfahrzeugsitz weist ein Sitzteil 1 auf, das mittels vorderer und hinterer als Lenker 3 ausgebildeter Schwenk träger an einer Längsverstellschiene 2 angelenkt ist. Die Längsverstellschiene 2 ist an der nicht dargestellten Ka rosserie eines Kraftfahrzeugs verschieblich geführt und ihr gegenüber verrastbar. Die Lenker 3 sind an einer ersten An lenkstelle 4 mit einem Sitzteilrahmen 1a und an einer zwei ten Anlenkstelle 5 mit auf der Längsverstellschiene 2 fe sten Lagerböcken 2a verbunden. Der Lenker 3 kann sowohl vorne und hinten als auch nur vorne oder hin ten eingesetzt sein. Im folgenden wird nur ein einziger Schwenkträger betrachtet.A motor vehicle seat has a seat part 1 , which is articulated on a longitudinal adjustment rail 2 by means of front and rear swivel supports designed as a handlebar 3 . The longitudinal adjustment rail 2 is slidably guided on the body of a motor vehicle, not shown, and can be locked relative to it. The handlebars 3 are connected to a first steering point 4 with a seat frame 1 a and at a two-th articulation point 5 with on the longitudinal adjustment rail 2 fe most pedestals 2 a. The handlebar 3 can be used both front and rear as well as only front or rear. Only a single swivel bracket is considered below.
An dem Sitzteilrahmen 1a ist ein Bügel 1b befestigt, der einen Anlenkbolzen 4b mit einer Anlenkachse 4a trägt. Par allel zur Anlenkachse 4a verläuft eine Anlenkachse 5a eines Anlenkbolzens 5b, der im Lagerbock 2a aufgenommen ist. Der in Fig. 2 obere Anlenkbolzen 4b bildet die erste Anlenk stelle 4, der untere Anlenkbolzen 5b die zweite Anlenkstel le 5. Auf den beiden Anlenkbolzen 4b und 5b ist der aus drei Schichten 3a, 3b und 3c bestehende Lenker 3 ver schwenkbar gelagert. Die Schicht 3a mit dem kleinsten Quer schnitt ist mittels Bohrungen 3h und 31 unverschieblich auf den Anlenkbolzen 4b und 5b befestigt. Die Schichten 3b und 3c weisen Langlöcher 3f und 3g bzw. 3d und 3e auf, mit de nen die Schichten 3b und 3c auf den Anlenkbolzen 4b und 5b verschieblich geführt sind. Das Langloch 3d ist länger als das Langloch 3f. Es ragt in Längsrichtung zu beiden Seiten über das Langloch 3f hinaus. Genauso ist das Langloch 3e der Schicht 3c länger als das Langloch 3g in der Schicht 3b.On the seat frame 1 a bracket 1 b is attached, which carries a pivot pin 4 b with a pivot axis 4 a. Par allel to the pivot axis 4 a runs a pivot axis 5 a of a pivot pin 5 b, which is received in the bracket 2 a. The upper articulation pin 4 b in FIG. 2 forms the first articulation point 4 , the lower articulation pin 5 b the second articulation point 5 . On the two pivot pins 4 b and 5 b of the three layers 3 a, 3 b and 3 c handlebar 3 is pivotally mounted ver. The layer 3 a with the smallest cross section is fixed by means of holes 3 h and 31 immovably on the pivot pins 4 b and 5 b. The layers 3 b and 3 c have elongated holes 3 f and 3 g or 3 d and 3 e with which the layers 3 b and 3 c are displaceably guided on the pivot bolts 4 b and 5 b. The elongated hole 3 d is longer than the elongated hole 3 f. It protrudes in the longitudinal direction on both sides beyond the elongated hole 3 f. Likewise, the elongated hole 3 e in layer 3 c is longer than the elongated hole 3 g in layer 3 b.
Im Normalfall wird die Last von der unverschieblich gela gerten Schicht 3a aufgenommen. Die übrigen Schichten 3b und 3c tragen allenfalls im Umfang ihrer gegenseitigen Reibung zur Lastaufnahme bei. Wenn die Tragfähigkeit der Schicht 3a, z. B. infolge eines Frontalaufpralls, überschritten wird, knickt die Schicht 3a zur Seite aus, wie Fig. 3 zeigt. Die Anlenkbolzen 4b und 5b verschieben sich dabei in ihren Langlöchern 3f und 3g. Die Endbereiche der Schicht 3a gleiten auf der Schicht 3b. Der Sitzrahmen 1a senkt sich bis zur Anlage der Anlenkbolzen 4b und 5b an die einander zugewandten Innenwandbereiche der Langlöcher 3f und 3g. Durch die Verformung der Schicht 3a wird Energie aufge zehrt.In the normal case, the load is taken up by the immovably layer 3 a. The remaining layers 3 b and 3 c contribute at most to the extent of their mutual friction to the load bearing. If the load-bearing capacity of layer 3 a, z. B. is exceeded as a result of a frontal impact, the layer 3 a buckles to the side, as shown in FIG. 3. The pivot pins 4 b and 5 b shift in their elongated holes 3 f and 3 g. The end portions of the layer 3 a slide on the layer 3 b. The seat frame 1 a lowers until the pivot bolts 4 b and 5 b abut against the mutually facing inner wall regions of the elongated holes 3 f and 3 g. The deformation of layer 3 a consumes energy.
Die Schicht 3b, die eine höhere Steifigkeit als die Schicht 3a aufweist, übernimmt einen Großteil der Traglast. Wenn die Belastung auch die Tragfähigkeit dieser Schicht 3b übersteigt, knickt auch die Schicht 3b aus. Entsprechend der vorstehenden Beschreibung für die schwächere Schicht 3a kommt es wieder zu einer Verschiebung der Anlenkbolzen 4b und 5b in den Langlöchern 3d und 3e bis die Schicht 3c die Last hauptsächlich übernimmt. Dabei wird durch die weitere Verformung der Schicht 3a und die Verformung der Schicht 3b kinetische Energie in Verformungsarbeit umgewandelt.Layer 3 b, which has a higher rigidity than layer 3 a, takes over a large part of the load. If the load also exceeds the load-bearing capacity of this layer 3 b, layer 3 b also buckles. According to the above description for the weaker layer 3 a, there is again a displacement of the pivot pins 4 b and 5 b in the elongated holes 3 d and 3 e until layer 3 c mainly takes over the load. The further deformation of layer 3 a and the deformation of layer 3 b convert kinetic energy into deformation work.
Für die Verschiebung der Anlenkstellen 4 und 5 relativ zu einander ist die Anordnung von Langlöchern an einer der An lenkstellen 4 oder 5 ausreichend. An der jeweils anderen Anlenkstelle kann der Lenker 3 unverschieblich gelagert werden. Wenn die beim gegenseitigen Verschieben zwischen den Schichten 3a, 3b und 3c auftretende Reibung ebenfalls für den Energieverzehr ausgenutzt werden soll, müssen die Schichten im Bereich der Anlenkstellen 4 und 5 mit defi nierter Kraft aneinandergepreßt werden. Die Verschwenkbar keit des Schwenkträgers darf dadurch jedoch nicht einge schränkt sein.For the displacement of the articulation points 4 and 5 relative to each other, the arrangement of elongated holes at one of the articulation points 4 or 5 is sufficient. At the other articulation point the handlebar 3 can be mounted immovably. If the friction occurring between the layers 3 a, 3 b and 3 c should also be used for energy consumption, the layers in the area of the articulation points 4 and 5 must be pressed together with defined force. The swiveling speed of the swivel bracket must not be restricted by this.
Der beschriebene Lenker 3 wird auch bei Zugbelastung in analoger Weise zum Energieabbau eingesetzt. Diese Belastung kann beispielsweise für die vorderen Lenker 3 eines Kraft fahrzeugsitzes bei einem Heckaufprall auftreten. Die ein zelnen Schichten 3a und 3b werden bei Überschreiten der Elastizitätsgrenze bleibend gedehnt und verzehren dadurch Energie. Die Dehnung der schwächsten Schicht 3a kann sogar bis zum Überschreiten der Streckgrenze und damit bis zu ih rem Abreißen zugelassen werden. Die Dehnung erfolgt wieder stufenweise dadurch, daß die Anlenkbolzen 4b und 5b sich nacheinander an die voneinander abgewandten Wandbereiche der Langlöcher 3d und 3e bzw. 3f und 3g anlegen.The handlebar 3 described is used in an analogous manner for energy reduction even under tensile load. This load can occur for example for the front link 3 of a motor vehicle seat in a rear-end collision. The individual layers 3 a and 3 b are permanently stretched when the elastic limit is exceeded and thus consume energy. The stretching of the weakest layer 3 a can even be permitted until the yield point is exceeded and thus until it breaks off. The stretching is again carried out step by step in that the pivot pins 4 b and 5 b successively bear against the wall regions of the elongated holes 3 d and 3 e or 3 f and 3 g facing away from one another.
