Abstract

In order, in the event of a collision, to prevent belt forces being introduced via the adjusting device of a vehicle seat, the belt lock is fastened on a slide which surrounds a rail fixed to the vehicle and extending in the longitudinal direction of the vehicle and which is fixed on the seat side via a support bracket and which, on the occurrence of a high degree of tensile stress on the belt, carries out a tipping movement about its rail-side articulation point. In this connection, a profiled section extending in the region of the lower and upper narrow side of the rail is deformed so that the slide is anchored firmly to the rail.

Description

"Einem Kraftfahrzeugsitz zugeordnetes"Associated with a motor vehicle seat

Gurtschloß" Die Erfindung bezieht sich auf ein einem Kraftfahrzeugsitz zugeordnetes Gurtschloß, das -an einem, eine in Fahrzeuglängsrichtung verlaufende fahrzeugfeste Schiene umgreifenden Schieber befestigt ist, wobei dieser über eine Stützlasche mit dem Kraftfahrzeugsitz verbunden ist und beim Auftreten einer Zugbelas;tung am Gurt um seine schienenseitige Anlenkstelle eine Kippbewegung ausführt, die zu einem Verklemmen des Schiebers mit der Schiene führt. Belt buckle "The invention relates to a vehicle seat Associated belt buckle, the one extending in the longitudinal direction of the vehicle vehicle-fixed rail encompassing slide is attached, this via a Support bracket is connected to the motor vehicle seat and when a tensile load occurs performs a tilting movement on the belt around its articulation point on the rail side, which leads to jamming of the slide with the rail leads.

Eine derartige Anordnung ist durch die DE-PS 11 52 907 bekannt und bietet aufgrund der glatten Oberfläche der Schiene wohl die Gewähr für ein leichtes Verschieben des Sitzes, jedoch kann bei einer großen Zugbelastung am Gurt, wie sie bei einer Fahrzeugkollision auftreten kann, nicht ausgeschlossen werden, daß die Klemmwirkung zwischen Schieber und Schiene nicht ausreicht und es zu einer Einleitung von Gurtkräften in die FUhrungseinrichtung des Sitzes kommt.Such an arrangement is known from DE-PS 11 52 907 and due to the smooth surface of the rail, it is a guarantee of a light weight Moving the seat, however, can with a large tensile load on the belt like them can occur in a vehicle collision, it cannot be ruled out that the The clamping effect between the slide and the rail is not sufficient and it leads to an initiation comes from belt forces in the guide device of the seat.

Es ist Aufgabe der Erfindung, eine Einrichtung zi schaffen, bei der unter Beibehaltung einer leichten Sitzverschiebbarkeit GurtlerSifto ulltex Umgehung der Sitzführungseinrichtung nur (iber die schiene in die Fahrzeugkarroserie eingeleitetwerden.It is the object of the invention to provide a device zi in which GurtlerSifto ulltex bypassing the seat while maintaining the ease with which the seat can be moved the seat guide device only (via the rail in the vehicle body be initiated.

Deshalb wird ein einem Kraftfahrzeugsitz zugeordnetes Gurtschloß der eingangs genannten Art vorgeschlagen, wobei erfindungsgemäß die Schiene an ihrer oben- und untenliegenden Schmalseite einen durchgehenden, durch Eindicken leicht deformierbaren Profilabschnitt aufweist.Therefore, a belt buckle assigned to a motor vehicle seat is the Proposed type mentioned initially, according to the invention, the rail on their Upper and lower narrow side a continuous, slightly thickened Has deformable profile section.

Eine einfache Herstellung der Schiene z. B. durch Strangpressen ist gegeben, wenn der Profilabschnitt an der Schiene angeformt ist.A simple production of the rail z. B. is by extrusion given when the profile section is formed on the rail.

Dabei kann der Profilabschnitt als Hohlprofil ausgebildet sein, oder ein offenes Profil aufweisen.The profile section can be designed as a hollow profile, or have an open profile.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnung näher erläutert. Es zeigen: Fig. 1 eine erfindungsgemäße Gurtschloßanordnung bei normalem Fahrbetrieb-, Fig. 2 eine Seitenansicht der Darstellung nach Fig. 1, Fig. 3 die Anordnung gemäß Fig. 1 im Augenblick des Auftretens einer großen Zugbelastung am Gurtschloß, und die Fig. 4a bis 4c unterschiedliche Profilausbildungen der Schiene.An exemplary embodiment of the invention is described below with reference to FIG Drawing explained in more detail. 1 shows a belt lock arrangement according to the invention during normal driving, FIG. 2 is a side view of the illustration according to FIG. 1, 3 shows the arrangement according to FIG. 1 at the moment when a large tensile load occurs on the buckle, and Figs. 4a to 4c different profile designs of the rail.

Vom Unterrahmen 1 eines in nicht dargestellter Weise lkngs-und höhenverschiebbaren Fahrzeugsitzes erstreckt sich eine beiderseits gelenkig befestigte Stützlasche 2 zu einem Schieber 3, der eii Gurtschloß 4 aufnimmt. Der Schieber 3 umgreift - wie insbesondere Fig. 2 zeigt - eine in Fahrzeuglängsrichtung verlaufende und karosseriefeste Schiene 5, die im Bereich ihrer oben- und untenliegenden Schmalseite 6 mit einem durchlaufenden Profilabschnitt 7 versehen ist; vieler beispielsweise. aus den Fig. 4å bis Ltd hervorgeht.From the subframe 1, one that is longitudinally and vertically displaceable in a manner not shown A support bracket 2 hinged on both sides extends across the vehicle seat to a slide 3, the eii buckle 4 takes. The slider 3 encompasses - as FIG. 2 in particular shows - one that extends in the longitudinal direction of the vehicle and body-fixed rail 5, which is in the area of its upper and lower narrow side 6 is provided with a continuous profile section 7; many for example. from Figs. 4å to Ltd emerges.

Im normalen Fahrbetrieb. gleitet bei einer Sitzverstellbewegung der Schieber 3 ohne merkbaren Widerstand auf der Schiene 5, die zur weiteren Verringerung der Reibung und zum Ausschalten von Geräuschen mit einer nicht dargestellten Beschichtung versehen sein kann.During normal driving. slides during a seat adjustment movement Slide 3 without noticeable resistance on the rail 5, which leads to further reduction the friction and to switch off noises with a coating, not shown can be provided.

Tritt am Gurtschloß 4 eine größere Zugbelastung auf, so führt der Schieber 3 um seine Anlenkstelle 8 an der Stützlasche 2 eine Kippbewegung aus, wie dies in Fig. 3 dargestellt ist. Dabei erfolgt eine örtliche Deformation des oberen- und unteren Profilabschnittes 7 durch den Schieber 3, der somit unverrückbar an der Schiene 5 festgelegt wird, so daß die auftretenden Kräfte unter Umgehung der Sitzführungseinrichtung nur über die Schiene 5 in die Karosserie eingeleitet werden.If the belt buckle 4 is subject to a greater tensile load, then the Slide 3 to its articulation point 8 on the support bracket 2 from a tilting movement, such as this is shown in FIG. 3. A local deformation of the upper and lower profile section 7 by the slide 3, which is thus immovable the rail 5 is set so that the forces that occur bypassing the Seat guide device can only be introduced into the body via the rail 5.

Die Profilabschnitte 7 werden vorzugsweise durch einen Strangpreßvorgang zusammen mit der übrigen Schiene 5 gefertigt, wobei offene Profilformen (Fig. 4a und 4d) und Hohlprofilformen (Fig. 4b und 4c) möglich sind.The profile sections 7 are preferably made by an extrusion process manufactured together with the rest of the rail 5, with open profile shapes (Fig. 4a and 4d) and hollow profile shapes (Fig. 4b and 4c) are possible.
