Abstract
Description
Die Erfindung betrifft eine Vorrichtung zur Verriegelung einer Verstellvorrichtung für einen Fahrzeugsitz bei einem Crash, insbesondere zur Verriegelung einer Sitzhöhen-, Längs- oder Lehnenverstellvorrichtung gegen ungewollte Bewegung im Crashfall.The invention relates to a device for locking an adjusting device for a vehicle seat at a Crash, in particular for locking a seat height, longitudinal or backrest adjustment device against unwanted movement in the event of a crash.
Bei verstellbaren Fahrzeugsitzen besteht das Problem, daß sie unter den bei einem Crash auftretenden Kräften ruckartig ihre Stellung ändern und die Insassen einem Verletzungsrisiko aussetzen. Beispielsweise können die crashbedingten Kräfte eine vorwärts und aufwärts gerichtete Bewegung eines höhenverstellbaren Sitzes bewirken. Am Sitz befestigte Rückhaltesysteme wie das Schloß eines Sicherheitsgurts bewegen sich dabei mit und verlieren an Wirkung. Beim Sicherheitsgurt wird dies auch als Gurtpunktvorverlagerung bezeichnet.With adjustable vehicle seats the problem is that they suddenly change their position under the forces occurring in a crash and the Expose occupants to risk of injury. For example, the forces caused by a crash forward and up directional movement of a height adjustable Effect seat. Restraint systems attached to the seat like the lock of one Seat belts move with it and lose their effectiveness. In the case of the seat belt, this is also called the belt point advance designated.
Es sind bereits Vorrichtungen bekannt, die eine Sitzhöhenverstellung im Crashfall sperren, um die Gurtpunktvorverlagerung zu begrenzen, siehe DE-A-100 56 082.Devices are already known which is a seat height adjustment lock in the event of a crash to limit the belt point advance, see DE-A-100 56 082.
Von besonderem Interesse sind Verriegelungsvorrichtungen, die von einem Gurtstraffer ausgelöst werden, da dieser oft ohnehin am Sitz vorhandenen ist und im Verlauf eines Crashs meist relativ frühzeitig aktiviert wird. So bleibt die ungewollte Vorverlagerung des Sitzbenutzers beim Crash klein. Beispielsweise offenbart DE-A-100 41 827 einen Fahrzeugsitz mit einem Masseverriegelungselement, das so mit einer Gurtschloßbefestigung gekoppelt ist, daß die am Gurtschloß anliegenden Kräfte zusätzlich auf das Masseverriegelungselement einwirken und so den Eingriff der Verriegelung sichern.Locking devices are of particular interest, which are triggered by a belt tensioner, since this is often anyway is present at the seat and usually relatively early in the course of a crash is activated. So there remains the unwanted advance of the seat user small in the crash. For example, DE-A-100 41 827 discloses one Vehicle seat with a mass locking element, so with a Gurtschloßbefestigung is coupled that the close to the belt buckle personnel additionally on act the mass locking element and thus the engagement of the Secure the lock.
Bei Einsatz eines Gurtstraffers kann es jedoch vorkommen, daß dieser versagt und der Sitzbenutzer beim Crash eine unzulässig große Vorverlagerung erfährt. Das daraus resultierende erhöhte Verletzungsrisiko ist erheblich.When using a belt tensioner however, it does happen that this fails and the seat user in the event of an impermissibly large forward displacement experiences. The resulting increased Risk of injury is significant.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung zur Verriegelung einer Verstellvorrichtung eines Fahrzeugsitzes im Crashfall zu schaffen, die mit einem Gurtstraffer arbeitet und eine erhöhte Sicherheit bietet.The invention is therefore the object based on a device for locking an adjusting device to create a vehicle seat in the event of a crash using a belt tensioner works and an elevated Offers security.
Die Lösung dieser Aufgabe gelingt mit einer Vorrichtung nach Anspruch 1. Die abhängigen Ansprüche sind auf bevorzugte Ausführungsformen der Erfindung gerichtet.This task is solved with a device according to claim 1. The dependent claims are to preferred embodiments directed of the invention.
Eine erfindungsgemäße Verriegelungsvorrichtung sieht eine Gurtstraffer-betätigte Verriegelung eines verstellbaren Fahrzeugsitzes vor und nutzt ferner die bei Versagen oder Nichtansprechen des Gurtstraffers beim Crash auftretende Gurtkraft bzw. die damit verbundene Bewegung des Gurts, um auch in diesem Fall die Sitzverstellung gegen ungewollte Bewegung zu verriegeln. Eine unerwünschte Verstellung des Fahrzeugsitzes kann auch dann verhindert werden, wenn der Gurtstraffer nicht oder zumindest nicht vollständig ausgelöst wird.A locking device according to the invention sees a pretensioner operated Locking an adjustable vehicle seat in front and also uses those in the event of failure or failure of the pretensioner to crash occurring belt force or the associated movement of the belt, in this case too, the seat adjustment against unwanted movement to lock. An unwanted one Adjustment of the vehicle seat can also be prevented if the belt tensioner is not or at least not fully triggered.
Typischerweise ist ein Gurtstraffer dazu ausgelegt, bereits bei Beginn eines Crashs auszulösen. Dabei soll der Gurt straff gezogen, also verkürzt werden. Ohne Gurtstraffer oder bei Versagen. des Gurtstraffers wirkt die crashbedingte Gurtkraft in Gegenrichtung (gurtstreckend) und tritt erst mit einer gewissen Verzögerung nach dem Beginn des Crashs auf. Auch wenn die Gurtstraffer-ausgelöste und die von der crashbedingten Gurtkraft ausgelöste Verriegelung also im Prinzip mit zwei entgegengesetzten Gurtbewegungen einhergehen, können sie auf die gleichen Verriegelungselemente wirken, ohne daß es zu einer Konkurrenzsituation zwischen ihnen kommt. Denn die von der crashbedingten Gurtkraft ausgelöste Verriegelung wird erst dann bewirkt, wenn der Gurtstraffer keine Gurtstraffung vorgenommen hat.Typically is a belt tensioner designed to trigger at the start of a crash. there the belt should be pulled tight, i.e. shortened. Without belt tensioners or in the event of failure. the belt tensioner acts on the belt force caused by the crash in the opposite direction (belt stretching) and only occurs with a certain delay after the start of the crash. Even if the pretensioner-triggered and the locking mechanism triggered by the crash-related belt force in principle with two opposite belt movements, they can act on the same locking elements without it a competitive situation between them. Because that of belt force caused by a crash Locking is only effected if the belt tensioner does not Has tightened the belt.
Die Ausführungsform nach Anspruch 2 weist den Vorteil auf, daß der Eingriff von erstem und zweitem Verriegelungselement schnell und sicher aufgrund der Freigabe eines Energiereservoirs, beispielsweise einer Feder gemäß Anspruch 3 erfolgt. Damit wird eine Situation vermieden, in der die gesamte Betätigungskraft und der gesamte Betätigungsweg zum Eingriff der Verriegelungselemente von der Gurtkraft zur Ver fügung gestellt werden muß, was den Ansprechzeitpunkt der Verriegelung sonst stark von der jeweiligen Crashsituation abhängig machen würde.The embodiment according to claim 2 has the advantage that the Engagement of the first and second locking element quickly and safe due to the release of an energy reservoir, for example a spring according to claim 3 is done. This avoids a situation in which the entire operating force and the entire route of operation made available for engagement of the locking elements by the belt force must be what the response time of the locking otherwise strongly from the respective Depending on the crash situation would do.
Zweckmäßigerweise wird das Energiereservoir im Normalzustand gemäß Anspruch 4 von einer Sperre blockiert, die von der Gurtkraft im Crashfall freigegeben wird. Ein besonders präzise definiertes Ansprechen der Verriegelung im Crashfall ohne die Gefahr eines fehlerhaften Ansprechens außerhalb eines Crashs besteht bei der Ausführungsform nach Anspruch 5, in der die Sperre ein zerstörbares oder abscherbares Scherelement aufweist.The energy reservoir is expediently in the normal state according to claim 4 blocked by a lock released by the belt force in the event of a crash becomes. A particularly precise Defined response of the lock in the event of a crash without the danger there is a faulty response outside of a crash in the embodiment according to claim 5, in which the barrier is a destructible or shearable shear member having.
Die Auführungsformen der Ansprüche 6 bis 10 stellen zweckmäßige Kombinationen der Verriegelungsvorrichtung mit einem Gurtstraffer dar, die sich einfach fertigen lassen und ein präzises Ansprechen bei Versagen oder Nicht-Auslösen des Gurtstraffers bewirken.The embodiments of claims 6 to 10 make appropriate combinations the locking device with a belt tensioner, which itself simply have it manufactured and respond precisely in the event of failure or not triggering of the belt tensioner.
