Abstract

The invention relates to a vertically adjustable platform as can be found, for example, as a seat frame in a vertically adjustable motor-vehicle seat. In order to be able to design the drive element for the vertical adjustment in a simple, easy and cost-effective manner, links are provided which connect the platform to a base and can transmit large forces when required. In this arrangement, one guide link each of fixed length and one locking link each of variable length interact in a triangular assembly. If the locking link is locked to the locking link movable in it, a rigid assembly results which can transmit high compressive or tensile forces. During the vertical adjustment, the locking elements are unlocked and move in a positively guided manner by the locking link about an articulation point. <IMAGE>

Description

Die Erfindung betrifft eine höhenverstellbare Plattform, wie sie beispielsweise bei höhenverstellbaren Kraftfahrzeugsitzen zur Anwendung gelangt. Hierfür sind verschiedene Höhenverstellmechanismen bekannt geworden, die in der Lage sind, Kräfte bis zu einer bestimmten Größenordnung zu übertragen.The invention relates to a height-adjustable platform as it for example in the case of height-adjustable motor vehicle seats reached. Various height adjustment mechanisms are known for this become able to exert forces up to a certain level Transfer order of magnitude.

Der Erfindung liegt die Aufgabe zugrunde, eine Anbindung für eine stufenlos höhenverstellbare Plattform zu schaffen, die unabhängig vom Verstellmechanismus die Führung und Halterung der Plattform übernimmt und in der Lage ist, sehr große Kräfte zu übertragen, ohne Kosten und Gewicht nennenswert ansteigen zu lassen.The invention has for its object a connection for a continuously to create height adjustable platform that is independent of the Adjustment mechanism takes over the guiding and holding of the platform is able to transfer very large forces without cost and weight to increase significantly.

Eine solche Aufgabe stellt sich z. B., wenn der komplette Sicherheitsgurt in den Kfz-Sitz integriert wird. Dann wirken im Unfall erhebliche Kräfte auf den Sitzrahmen (=Plattform) ein, die in den Kfz-Boden eingeleitet werden müssen.Such a task arises, for. B. if the complete seat belt in the car seat is integrated. Then considerable forces act on the in the accident Seat frame (= platform), which must be introduced into the vehicle floor.

Diese Aufgabe wird gemäß der Erfindung gelöst durch die im Kennzeichnungsteil des Patentanspruches 1 angegebenen Maßnahmen. Vorteilhafte Ausgestaltungsformen der Erfindung ergeben sich aus den nachfolgenden Patentansprüchen.This object is achieved according to the invention by the Labeling part of claim 1 specified measures. Advantageous embodiments of the invention result from the subsequent claims.

Eine Basis, die z. B. bei einem Kfz-Sitz eine horizontal verfahrbare Schiene sein kann, ist über Lenker mit einer Plattform (beim Sitz der Sitzrahmen) verbunden. Die Art des Antriebes für die Höhenverstellung ist nicht dargestellt und ist für die vorliegende Erfindung auch nicht von Bedeutung.A basis that z. B. in a car seat a horizontally movable rail can be, is via handlebars with a platform (at the seat the seat frame) connected. The type of drive for the height adjustment is not shown and is also of no importance for the present invention.

Je ein Führungslenker und ein Blockierlenker sind zu einer Wirkeinheit zusammengefaßt. Bei einem Kfz-Sitz würden davon sinnvollerweise 4 Stück angeordnet sein, je 2 rechts und links. Der Führungslenker mit einer fixen Länge sorgt dafür, daß die Plattform auf einer vorgegebenen Kurve höhenverstellt wird. Der Blockierlenker, der reibungsarm innerhalb eines Blockierelementes gleitet, wird in einer Zwangsbewegung mitgeführt. One control arm and one locking arm each form an effective unit summarized. In a car seat, 4 would be useful be arranged, 2 on the right and 2 on the left. The guide link with a fixed Length ensures that the platform is on a given curve is adjusted in height. The anti-lock bar, the low-friction within a Blocking element slides, is carried in a forced movement.  

lm verriegelten Zustand der Blockierelemente bilden die Lenker einen starren Dreiecksverband, über den Zug- oder Druckkräfte zwischen Plattform und Basis übertragen werden können.When the blocking elements are locked, the handlebars form a rigid one Triangle, over the tensile or compressive forces between the platform and Base can be transferred.

ln der Fig. ist ein Ausführungsbeispiel dargestellt. Es zeigt eine Plattform 1, die über Lenker 3, 4 mit einer Basis 2 verbunden ist. Mit ausgezogenen Strichen ist die unterste Stellung dargestellt, in gestrichelter Form die obere Stellung. Die Bewegung der Plattform 1 ist zwangsweise vorgegeben durch die Schwenkbewegung der Führungslenker 3, wobei auf die Art des Höhenantriebes hier nicht näher eingegangen wird. Während der Verstellbewegung gleitet der Blockierlenker 4 reibungsarm in einem Blockierelement 5. Beide Teile (4 und 5) können sich dabei frei in ihren Gelenkpunkten 6 und 7 ausrichten.An embodiment is shown in FIG . It shows a platform 1 which is connected to a base 2 via links 3 , 4 . The bottom position is shown with solid lines, the top position in dashed lines. The movement of the platform 1 is inevitably predetermined by the pivoting movement of the guide link 3 , the type of vertical drive not being discussed in detail here. During the adjustment movement, the blocking link 4 slides with little friction in a blocking element 5 . Both parts ( 4 and 5 ) can align freely in their hinge points 6 and 7 .

Grundsätzlich bieten sich zwei Arten der Verriegelung im Blockierelement 5 an. Einerseits kann der Normalzustand die ständige Verriegelung sein. Soll die Plattform verstellt werden, so wird - z. B. über einen Hubmagneten - eine Entriegelung eingeleitet. Andererseits ist es auch möglich, das Blockierelement 5 ständig entriegelt zu lassen und nur in einer Sondersituation - z. B. im Unfall bei einem Kfz-Sitz, wenn große Kräfte äbgestützt werden müssen - eine Verriegelung einzuleiten. Hierfür bieten sich Blockierelemente an, wie sie in der P 36 12 474 beschrieben sind. Sie leiten dann eine Verriegelung ein, wenn eine bestimmte Beschleunigungsschwelle (Stoß, Aufprall) überschritten wird.There are basically two types of locking in the blocking element 5 . On the one hand, the normal state can be the permanent locking. If the platform is to be adjusted, then - e.g. B. via a solenoid - initiated an unlocking. On the other hand, it is also possible to keep the blocking element 5 permanently unlocked and only in a special situation - e.g. B. in an accident in a car seat when large forces have to be supported - initiate a lock. Blocking elements, as described in P 36 12 474, are suitable for this. They then initiate an interlock if a certain acceleration threshold (impact, impact) is exceeded.

Im verriegelten Zustand des Blockierlenkers entsteht ein starrer Dreiecks­ verband, der gut in der Lage ist, Kräfte zu übertragen und die Antriebseinheit für die Höhenverstellung zu entlasten. Auch Momente, die auf die Plattform einwirken, können gut abgeleitet werden, wenn der vordere Dreiecksverband Druckkräfte und der hintere Zugkräfte überträgt.A rigid triangle is formed when the blocking link is locked who is well able to transmit forces and who Relieve the drive unit for the height adjustment. Even moments that arise The platform act can be well derived if the front one Triangular association transfers compressive forces and the rear tensile forces.
