Description
Die Erfindung betrifft einen Rastbeschlag für einen Fahrzeugsitz, insbesondere für einen Kraftfahrzeugsitz, mit den Merkmalen des Oberbegriffs des Patentanspruches 1.The The invention relates to a locking fitting for a vehicle seat, in particular for one Motor vehicle seat, with the features of the preamble of the claim 1.
Bei einem bekannten Rastbeschlag ist das Beschlagoberteil auf einem Lagerelement gelagert, das wiederum im Beschlagunterteil gelagert ist. Das in einem Bauraum zwischen dem Beschlagoberteil und dem Beschlagunterteil angeordnete und als komplizierter Kragenzug ausgebildete Lagerelement dient zugleich auch als Steuerscheibenelement zur Bewegung zweier Riegel, die zum Einrasten des Rastbeschlages in einer Führung geführt radial nach außen gedrückt werden. Das kombinierte Lager- und Steuerscheibenelement sitzt direkt auf einer Stange, die nach dem Einbau des Rastbeschlages in einen Fahrzeugsitz zum Beschlag auf der anderen Seite und zu einer Einstellvorrichtung führt. Durch Drehung der Stange dreht sich das Lager- und Steuerscheibenelement und bewegt dadurch die Riegel.at a known locking fitting is the top fitting on a Bearing element stored, which in turn is stored in the lower fitting part is. That in a space between the top fitting and the Lower fitting part arranged and designed as a complicated collar pull Bearing element also serves as a control disc element for movement two latches, which guided in a guide to engage the locking fitting radially outward depressed become. The combined bearing and control disc element sits directly on a pole after installing the locking fitting in a vehicle seat to the fitting on the other side and to an adjustment device leads. By rotating the rod, the bearing and control disc element rotates and thereby moves the bars.

Der Erfindung liegt die Aufgabe zu Grunde, einen Rastbeschlag der eingangs genannten Art in Hinblick auf ein sicheres Verriegeln des Rastbeschlags und eine Verringerung der Toleranzen zu verbessern.The The invention is based on the object of a locking fitting at the beginning mentioned type with regard to a secure locking of the locking fitting and improve a reduction in tolerances.
Diese Aufgabe wird erfindungsgemäß durch einen Rastbeschlag mit den Merkmalen des Patentanspruches 1 gelöst. Vorteilhafte Ausgestaltungen sind Gegenstand der Unteransprüche.This The object is achieved by a Detent fitting with the features of claim 1 solved. advantageous Refinements are the subject of the dependent claims.
Dadurch, daß die Steuerscheibe, welche beispielsweise über Vorsprünge und Kulissen die Bewegung des Riegels insbesondere beim Entriegeln steuert, in Richtung auf den Riegel zu vorgespannt, also bei einem radial beweglichen Riegel in axialer Richtung vorgespannt ist, ist gewährleistet, daß die Steuerscheibe in Anlage an den Riegel bleibt und damit die Vorsprünge und Kulissen zur Steuerung der Bewegung in Eingriff bleiben. Die Vorspannung wird durch eine oder mehrere federnde Zungen erreicht, welche beispielsweise aus der Steuerscheibe herausgebogen sind und zugleich als Toleranzausgleichsmittel wirken. Mit solchen Toleranzausgleichsmittel können Toleranzen innerhalb eines Beschlags ausgeglichen werden. Es sind verschiedene Toleranzausgleichsmittel möglich, die einzeln oder in beliebigen Kombinationen vorgesehen sein können.Thereby, that the Control disc, which, for example, over protrusions and scenes the movement controls the bolt, especially when unlocking, in the direction of the bolt too pre-tensioned, i.e. with a radially movable bolt is biased in the axial direction, it is ensured that the control disc remains in contact with the bolt and thus the projections and Scenes to control the movement remain engaged. The preload is achieved by one or more resilient tongues, which for example are bent out of the control disc and at the same time as tolerance compensation means Act. With such tolerance compensation means, tolerances within a Fitting are compensated. There are different means of tolerance compensation possible, which can be provided individually or in any combination.
Auch das Steuerstück ist mit seinem sich nach außen mit immer größerem Radius erstreckenden Spannkurvenbereich für jeden vorhandenen Riegel ein Toleranzausgleichsmittel. Ein bereits teilweise eingefallener Riegel wird dadurch sicher gehalten, bis auch die anderen Riegel eingefallen sind. Eine bessere Kraftübertragung wird durch die Steuernocken auf den Riegeln erreicht, die mit dem jeweiligen Spannkurvenbereich zusammenwirken.Also the control piece is with his face out with an ever larger radius extending span curve range for each existing bar a tolerance compensator. An already partially collapsed one Bolt is held securely until the other bolts have come up. The control cam provides a better power transmission reached on the bars with the respective span curve range interact.
Das Steuerstück bewegt die vorhandenen Riegel, wobei das Steuerstück durch eine gemeinsame Betätigung einer Stange bewegt wird, welche die Bewegung des Steuerstücks von einer Fahrzeugsitzseite auf die andere Fahrzeugsitzseite überträgt. Dies bewirkt eine synchrone Betätigung aller vorhandener Riegel. Die Toleranzausgleichsmittel sorgen beispielsweise dafür, daß beide Beschläge verriegeln, unabhängig davon, ob durch ein gewollt ausgebildetes oder durch Fertigungstoleranzen entstandenes Spiel innerhalb eines Beschlags oder zwischen beiden Beschlägen unterschiedliche Zahnstellungen in den Rastbeschlägen auftritt. Um Torsionen der Stange auszugleichen, ist vorzugsweise zwischen der Stange und dem Steuerstück ein Spiel vorgesehen. Für eine einfachere Herstellung ist es von Vorteil, wenn das Spiel zwischen einem auf der Stange angeordneten, gesondert hergestellten, aber im Vergleich zur Stange kurzen Übertragungselement und dem Steuerstück vorgesehen ist.The control piece moves the existing latch, taking the control piece through a common activity a rod is moved which controls the movement of the control piece of transfers one vehicle seat side to the other vehicle seat side. This causes synchronous actuation all existing bars. The tolerance compensation means, for example for this, that both Forged lock independently whether through intentional training or through manufacturing tolerances game created within a fitting or between the two fittings different tooth positions occur in the locking fittings. In order to compensate for torsion of the rod, it is preferable between Rod and the control piece provided a game. For a simpler manufacture, it is advantageous if the game between one on the bar, made separately, but compared to the rod short transmission element and the control piece is provided.
Ein Fahrzeugsitz weist wenigstens einen, vorzugsweise zwei der erfindungsgemäßen Rastbeschläge auf, die über die Stange miteinander verbunden sind.On Vehicle seat has at least one, preferably two, of the locking fittings according to the invention, the above the rod are connected together.
