Description
Die Erfindung betrifft eine Längseinstellvorrichtung für einen Fahrzeugsitz, insbesondere für einen Kraftfahrzeugsitz, mit den Merkmalen des Oberbegriffs des Anspruches 1.The The invention relates to a longitudinal adjustment device for one Vehicle seat, especially for a motor vehicle seat, with the features of the preamble of Claim 1.
Bei manuell längseinstellbaren Fahrzeugsitzen kann es sein, dass kurz vor einem Crash der Sitzbenutzer zufällig die Verriegelung gelöst hat, um den Fahrzeugsitz zu verstellen. Tritt dann der Crashfall ein, so wird der Fahrzeugsitz beschleunigt. Aufgrund der hohen Relativgeschwindigkeit kann auch bei losgelassenem Verriegelungshebel die Verriegelung nicht mehr einfallen. Der Fahrzeugsitz fährt dann bis zum Endanschlag und wird dann schlagartig abgebremst, was Verletzungen beim Sitzbenutzer hervorrufen kann.at manually adjustable Vehicle seats may be that just before a crash, the seat occupant fortuitously the lock released has to adjust the vehicle seat. Then the crash occurs a, the vehicle seat is accelerated. Due to the high relative speed can lock even when the lock lever is released do not remember. The vehicle seat then moves to the end stop and then suddenly slowed down causing injury to the seat occupant can.
In
der
Der Erfindung liegt die Aufgabe zu Grunde, eine Längseinstellvorrichtung der eingangs genannten Art zu verbessern. Diese Aufgabe wird erfindungsgemäß durch eine Längseinstellvorrichtung mit den Merkmalen des Anspruches 1 gelöst. Vorteilhafte Ausgestaltungen sind Gegenstand der Unteransprüche.Of the Invention is the object of a Längseinstellvorrichtung the to improve the type mentioned above. This object is achieved by a longitudinal adjustment device solved with the features of claim 1. Advantageous embodiments are the subject of the dependent claims.
Das Massestück ist ein leicht herzustellender, durch seine Trägheit im Crashfall ansprechender Beschleunigungssensor. Um die Empfindlichkeit dieses Beschleunigungssensors zu erhöhen, wird das Massestück im Normalgebrauch der Längseinstellvorrichtung kraftschlüssig durch eine federbelastete Halteplatte gehalten. Diese Halteplatte bildet zugleich eine Führung für einen Rastbolzen, was die Zahl der Bauteile verringert. Nach Aufhebung des Reibschlusses mit dem Massestück im Crashfall bewegt sich die Halteplatte federunterstützt, womit ein schnelleres Verriegeln der Zusatzverriegelung erreicht werden kann. Zudem wird durch die erfindungsgemäße Lösung verhindert, dass bei nachlassender Beschleunigung bei Rückkehr des Massestück in seine Ruhelage die Zusatzverriegelung öffnet.The bulk Unit is an easy-to-manufacture, due to its inertia in the event of a crash appealing acceleration sensor. To increase the sensitivity of this acceleration sensor is the mass in normal use of the longitudinal adjustment device force fit held by a spring-loaded retaining plate. This holding plate at the same time forms a guide for one Locking bolt, which reduces the number of components. After cancellation the frictional engagement with the mass in the event of a crash moves the retaining plate spring-supported, thus achieving a faster locking of the additional locking can be. In addition, it is prevented by the inventive solution that decreases in Acceleration on return of the mass in its rest position the additional lock opens.
Mit der Zusatzverriegelung kann zum einen die Schienenanordnung für die im Normalgebrauch auftretenden Kräfte ausgelegt werden, d.h. schwächer und mit weniger Gewicht. Dies vereinfacht und verbilligt die Herstellung und führt zu einem geringeren Gesamtgewicht. Zum anderen wird verhindert, dass, wenn der Sitzbenutzer die Längseinstellvorrichtung kurz vor dem Eintritt des Crashfalls zufällig entriegelt hat, der Fahrzeugsitz durch den Crash bis zum Endanschlag beschleunigt wird. Durch die Zusatzverriegelung wird die daher Sicherheit erhöht und die Verletzungsgefahr für den Sitzbenutzer verringert.With the additional locking can on the one hand, the rail assembly for the im Normal use occurring forces be designed, i. weaker and with less weight. This simplifies and reduces production costs and leads to a lower total weight. On the other hand, it prevents if the seat occupant the Längseinstellvorrichtung just before the crash occurred accidentally unlocked, the vehicle seat accelerated by the crash to the end stop. By the Additional locking will therefore increase safety and the risk of injury for the Seat user reduced.
Es ist von Vorteil, wenn mehrere Rastöffnungen und wenigstens zwei Rastbolzen vorgesehen sind, welche im Crashfall gleichzeitig in zwei Rastöffnungen einfallen, um ein sicheres Verriegeln zu gewährleisten. Vorzugsweise sind vier nach dem Noniusprinzip angeordnete Rastbolzen vorgesehen, von denen wenigstens zwei im Crashfall in zwei langlochförmige Rastöffnungen einfallen und spielfrei oder nahezu spielfrei gehalten werden.It is advantageous if several detent openings and at least two Resting bolts are provided, which in the event of a crash simultaneously two detent openings come in to ensure a secure locking. Preferably four arranged on the vernier principle locking bolts provided, of which At least two fall in the event of a crash in two slot-shaped locking openings and play or kept almost free of play.
Ein Fahrzeugsitz mit einer erfindungsgemäßen Längseinstellvorrichtung kann auf einer einzigen Sitzseite oder auf jeder Sitzseite eine Zusatzverriegelung aufweisen. Mit der Zusatzverriegelung können auch fertige Fahrzeugsitze nachgerüstet werden.One Vehicle seat with a Längseinstellvorrichtung invention on a single side of the seat or on each side of the seat an additional locking exhibit. With the additional locking can also finished vehicle seats retrofitted become.
