Abstract
Kupplung zwischen zwei Zügen eines Fahrzeugsitzes, insbesondere eines Kraftfahrzeugsitzes, welche die beiden Züge (107, 108) wenigstens im Crashfall miteinander verbindet, dadurch gekennzeichnet, daß jeder der beiden Züge (107, 108) mit einer eigenen Zugeinheit (121, 124) verbunden ist, die innerhalb eines Gehäuses (111) der Kupplung (101) beweglich geführt ist, wobei Sperrmittel (131) vorgesehen sind, welche eine Wirkverbindung der beiden Zugeinheiten (121, 124) beschleunigungssensitiv steuern.clutch between two trains a vehicle seat, in particular a motor vehicle seat, which the two trains (107, 108) connects at least in the event of a crash, thereby characterized that each of the two moves (107, 108) is connected to its own train unit (121, 124), within a housing (111) the coupling (101) is movably guided , wherein locking means (131) are provided which have an operative connection control the two train units (121, 124) in an acceleration-sensitive manner.
Description
Die Erfindung betrifft eine Kupplung zwischen zwei Zügen eines Fahrzeugsitzes mit den Merkmalen des Oberbegriffs des Anspruches 1.The The invention relates to a coupling between two trains of a vehicle seat the features of the preamble of claim 1.
Mit einer bekannten Kupplung dieser Art werden zwei Züge, beispielsweise Seilzüge oder Bowdenzüge, fest miteinander verbunden. Mit den Zügen werden beispielsweise Betätigungselemente oder Sensoren mit Verriegelungen von Sitzkomponenten verbunden, um letztere zu öffnen, wobei die Sitzkomponenten vorgespannt sein können. Sofern die Züge teilweise zugänglich verlegt sind, beispielsweise vom Fußbereich eines dahinter angeordneten Fahrzeugsitzes zugänglich sind, besteht die Gefahr eines Mißbrauchs, d.h. die Verriegelung der Sitzkomponente kann geöffnet werden ohne daß das Betätigungselement betätigt wurde.With a known coupling of this type, two trains, for example cables or Bowden cables, firmly connected. With the trains, for example, actuators or sensors connected with locking of seat components, to open the latter, the seat components can be biased. Unless the trains partially accessible are laid, for example from the foot area of one arranged behind it Vehicle seat accessible there is a risk of misuse, i.e. the lock the seat component can be opened be without that actuator actuated has been.
Der Erfindung liegt die Aufgabe zu Grunde, eine Kupplung der eingangs genannten Art zu verbessern. Diese Aufgabe wird erfindungsgemäß durch eine Kupplung mit den Merkmalen des Anspruches 1 gelöst. Vorteilhafte Ausgestaltungen sind Gegenstand der Unteransprüche.The The invention is based on the object of a coupling of the beginning to improve the type mentioned. This object is achieved according to the invention a clutch with the features of claim 1 solved. advantageous Refinements are the subject of the dependent claims.
Dadurch, daß jeder der beiden Züge mit einer eigenen Zugeinheit verbunden ist, die innerhalb eines Gehäuses der Kupplung beweglich geführt ist, wobei Sperrmittel vorgesehen sind, welche eine Wirkverbindung der beiden Zugeinheiten beschleunigungssensitiv steuern, kann bei crashaktiven Sitzkomponenten, wie beispielsweise Kopfstützen, eine mißbräuchliche Auslösung verhindert werden. Die erfindungsgemäße Kupplung kann an nahezu beliebiger Stelle des Fahrzeugsitzes angebracht werden, lediglich die Ausrichtung zur Fahrtrichtung ist in der Regel für die Beschleunigungssensivität zu beachten. Die erfindungsgemäße Kupplung kann in die Auslöselinien verschiedener crashaktiver Sitzkomponenten eingebaut werden, und zwar zwischen einem Sensor oder einem Betätigungselement einerseits und der crashaktiven Sitzkomponente andererseits.Thereby, that everybody of the two trains is connected to its own train unit, which is within a housing the coupling is movably guided is, locking means are provided which have an operative connection of the two train units can be sensitive to acceleration crash-active seat components, such as headrests, an abusive release be prevented. The clutch according to the invention can almost can be attached anywhere in the vehicle seat, only the orientation to the direction of travel is usually to be observed for the acceleration sensitivity. The clutch according to the invention can in the trigger lines various crash-active seat components are installed, and between a sensor or an actuator on the one hand and the crash-active seat component on the other.
In einer bevorzugten Ausführungsform sind die beiden Zugeinheiten in der Grundstellung der Kupplung von einander getrennt, vorzugsweise durch eigene Federmittel unabhängig voneinander vorgespannt, und gelangen im Crashfall in Wirkverbindung, in besonders einfach herzustellender Weise in der vorgegebenen Zugrichtung der Züge in Anlage aneinander. Die Sperrmittel sperren beispielsweise die in Zugrichtung voreilende erste Zugeinheit in der Grundstellung der Kupplung, so daß sie beispielsweise auf Abstand zur in Zugrichtung zweiten Zugeinheit gehalten wird, und geben die erste Zugeinheit im Crashfall frei.In a preferred embodiment are the two traction units in the basic position of the clutch from separated from each other, preferably independently biased by their own spring means, and come into active connection in the event of a crash, in a particularly simple manner to be produced in the predetermined train direction of the trains in contact with each other. The blocking means block, for example, the one leading in the pulling direction first train unit in the basic position of the clutch, so that it for example is kept at a distance from the second pulling unit in the pulling direction, and release the first train unit in the event of a crash.
In bevorzugter, konstruktiv einfach zu verwirklichender Ausführung sind die Sperrmittel in der Grundstellung in der Bewegungsbahn der ersten Zugeinheit angeordnet, wobei sie außerhalb des Mißbrauchsfalls vorzugsweise im Abstand zur ersten Zugeinheit angeordnet sind, um eine Reibung bei Eintritt des Crashfalls zu vermeiden. Im Crashfall bewegen sich die Sperrmitel aus der Bewegungsbahn der ersten Zugeinheit. Als Sperrmittel ist vorzugsweise eine zugleich beschleunigungssensitive Masse vorgesehen, welche für eine geringe Reibung schwenkbar in einer im wesentlichen quer zur Fahrtrichtung ausgerichteten Lage gelagert ist.In preferred, structurally easy to implement execution the locking means in the basic position in the path of movement of the first Traction unit arranged, being outside of the misuse are preferably arranged at a distance from the first train unit in order to avoid friction when the crash occurs. In the event of a crash the blocking means move out of the movement path of the first train unit. The blocking means is preferably an acceleration-sensitive one at the same time Mass provided for low friction pivotable in a substantially transverse to Direction oriented position is stored.
