Abstract
Description
Die Erfindung betrifft ein Sitzschienenpaar für einen Fahrzeugsitz, insbesondere für einen Kraftfahrzeugsitz, mit den Merkmalen des Oberbegriffs des Anspruches 1.The The invention relates to a seat rail pair for a vehicle seat, in particular for one Motor vehicle seat, with the features of the preamble of the claim 1.
Bei einem bekannten Sitzschienenpaar dieser Art, welches auf der Fahrzeugsitzseite mit einem Gurtschloß angeordnet ist, ist am hinteren Ende (oder einem anderen kritischen Bereich) eine Verstärkung, insbesondere für die zweite Sitzschiene, vorgesehen. Damit wird vermieden, daß im Crashfall oder bei einem Gurtersatzlasttest in der vordersten Position die erste Sitzschiene aufgrund der über die Befestigungsstelle in die erste Sitzschiene eingeleiteten Kräfte – mit ihrem Verkrallungsbereich die zweite Sitzschiene abschneidet.at a known seat rail pair of this type, which on the vehicle seat side arranged with a belt buckle is at the far end (or another critical area) a reinforcement, especially for the second seat rail, provided. This avoids that in the event of a crash or in a belt replacement load test in the foremost position, the first Seat rail due to the over the attachment point introduced into the first seat rail forces - with their Verkrallungsbereich the second seat rail cuts off.
Der Erfindung liegt die Aufgabe zu Grunde, ein Sitzschienenpaar der eingangs genannten Art zu verbessern, insbesondere hinsichtlich Herstellungskosten und Gewicht. Diese Aufgabe wird erfindungsgemäß durch ein Sitzschienenpaar mit den Merkmalen des Anspruches 1 gelöst. Vorteilhafte Ausgestaltungen sind Gegenstand der Unteransprüche.Of the Invention is based on the object, a seat rail pair of to improve the type mentioned above, in particular with regard Production costs and weight. This object is achieved by a seat rail pair with the features of claim 1 solved. advantageous Embodiments are the subject of the dependent claims.
Dadurch, daß zwischen der Befestigungsstelle und dem Verkrallungsbereich eine Aussparung vorgesehen ist, können im Crashfall die über die Befestigungsstelle eingeleiteten Kräfte eine gezielte Deformation im Bereich der Aussparung vornehmen, wobei die Aussparung, genauer gesagt der Materialbereich um sie herum, im Kraftfluß zwischen Befestigungsstelle und Verkrallungsbereich liegt. Die Deformation senkt die Kraftweiterleistung auf dieser Fahrzeugsitzseite und gestaltet damit die Lastverteilung zwischen den beiden Fahrzeugsitzseiten gleichmäßiger. Dies bewirkt eine Reduktion der auf den Verkrallungsbereich wirkenden Teilkräfte. Gewichts- und kostenerhöhende Verstärkungen der zweiten Sitzschiene sind dann nicht notwendig. Außerdem wird im Crashfall noch etwas Energie dissipiert. Die Aussparung ist eine freie Aussparung, welche im Normalfall zwar auch im Kraftfluß zwischen der Befestigungsstelle und dem Verkrallungsbereich liegt, jedoch ohne sonstige Funktion ist und erst im Crashfall zum Einsatz kommt. Durch eine bevorzugt vorgesehene Einbuchtung am hinteren Rand der ersten Sitzschiene, welche im Normalfall ebenfalls keine Funktion aufweist, wird der Schutz vor einem Einschneiden dieses relativ scharfkantigen und sehr steifen Sitzschienenende in die zweite Sitzschiene verbessert.Thereby, that between the attachment point and the Verkrallungsbereich provided a recess is, can in the event of a crash the over the attachment point initiated forces a targeted deformation make in the area of the recess, with the recess, more precisely said the area of material around them, in the power flow between Fixing point and Verkrallungsbereich lies. The deformation lowers the power enhancement on this vehicle seat side and designed thus the load distribution between the two vehicle seat sides even. This causes a reduction of acting on the Verkrallungsbereich Part forces. Weight and cost increasing reinforcements the second seat rail are then not necessary. In addition, in the Crash case still dissipates some energy. The recess is one free recess, which in the normal case, although in the power flow between the attachment point and the Verkrallungsbereich lies, however is without any other function and is only used in the event of a crash. By a preferably provided indentation at the rear edge of first seat rail, which normally also no function the protection against cutting it becomes relative sharp-edged and very stiff seat rail end in the second seat rail improved.
In bevorzugter Ausführung ist die Aussparung schlitzförmig ausgebildet, was die Deformation an den Enden den Schlitzes konzentriert, und vorzugsweise gerade und vorzugsweise in Längsrichtung gestreckt, was den Kraftfluß optimiert und die Herstellung einfach hält. Es wird dann eine gezielte Bewegung des Materials vom Bereich der Mitte der Aussparung quer zur Längsrichtung der schlitzförmigen Aussparung erreicht. Die Aussparung ist vorzugsweise im Adapterbereich, also in der Nähe der Befestigungsstelle ausgebildet und vorzugsweise direkt unterhalb derselben angeordnet, was die anderen Bereiche besser abschirmt. Insbesondere bei einem unsymmetrischen Schienenprofil, welches auch unsymmetrisch belastet ist, ist es von Vorteil, wenn die Aussparung quer zur Längsrichtung den Adapterbereich nur teilweise durchdringt, beispielsweise nur in einer Schicht von zwei aneinanderliegenden Schichten ausgebildet ist, welche zusammen den Adapterbereich bilden.In preferred embodiment the recess is slit-shaped formed, which concentrates the deformation at the ends of the slot, and preferably straight and preferably longitudinally stretched, which optimizes the power flow and keeping the production simple. It will then be a targeted movement of the material from the area of Center of the recess transverse to the longitudinal direction the slit-shaped Recess reached. The recess is preferably in the adapter area, so close the attachment point formed and preferably directly below the same, which shields the other areas better. Especially with an asymmetrical rail profile, which is also asymmetrical is loaded, it is advantageous if the recess transverse to the longitudinal direction the adapter area only partially penetrates, for example, only in formed of a layer of two adjacent layers is, which together form the adapter area.
Das erfindungsgemäß ausgebildete Sitzschienenpaar ist für alle Arten von längseinstellbaren Fahrzeugsitzen einsetzbar, um eine verbesserte Lastverteilung zu fördern.The formed according to the invention Seat rail pair is for all types of longitudinally adjustable vehicle seats used to promote improved load distribution.
Die Wirkung der Aussparung ist aber am größten, wenn das an der Befestigungsstelle angeordnete Strukturteil starr am Adapterbereich angebracht ist.The However, the effect of the recess is greatest when that at the attachment point arranged structural part is rigidly mounted on the adapter area.
