Abstract
Description
Die Erfindung betrifft einen Kraftfahrzeugsitz mit einer Verstellvorrichtung zur Höhen- und Neigungsverstellung.The The invention relates to a motor vehicle seat with an adjusting device to altitude and tilt adjustment.

solcher Kraftfahrzeugsitz ist z.B. aus der
Die
in der
Auch bei diesen beiden bekannten Einrichtungen erfolgt im Crashfall ein Verschwenken des Gurtschlosses in Querrichtung.Also in these two known devices takes place in the event of a crash Swiveling the buckle in the transverse direction.
Hiervon ausgehend liegt der vorliegenden Erfindung die Aufgabe zugrunde, einen gattungsgemäßen Kraftfahrzeugsitz dahingehend weiter zu entwickeln, daß eine zuverlässige Kraftübertragungseinrichtung bereitgestellt wird, wobei die Einleitung der Gurtkraft querkraftfrei erfolgen kann.Of these, The present invention is based on the object, a generic motor vehicle seat to further develop that a reliable power transmission device is provided, the introduction of the belt force without lateral forces can be done.
Die Lösung dieser Aufgabe erfolgt mit den Merkmalen des Patentanspruchs 1.The solution This object is achieved with the features of claim 1.
Die Kraftübertragung erfolgt im Normalbetrieb des Kraftfahrzeugsitzes über die Gurtaufnahme, über das Gelenk, das der Gurtaufnahme zugeordnet ist, weiter über das Verbindungsmittel und schließlich über das Gelenk, das dem Sitzrahmen zugeordnet ist, so daß vom Sitzrahmen aus über die Verstellvorrichtung für Höhe und/oder Neigung im Normalbetrieb auftretende Kräfte in das Chassis eines Kraftfahrzeugs einleitbar sind. Wenn in die Gurtaufnahme besonders hohe Kräfte eingeleitet werden, ist der Abstand zwischen dem genannten ersten und zweiten Gelenk verlängerbar, so daß sich der Abstand der dazwischen liegenden Gelenke, denen die Rastmittel zugeordnet sind, verkürzt, so daß diese mit einem am Chassis gelagerten Gegenbereich in Eingriff kommen können. Durch die Verwendung eines Gelenkvierecks können die Kräfte mittig eingeleitet werden, wodurch das Verbindungsmittel direkt auf Zug belastbar ist, ohne daß Querkräfte aufgenommen werden müßten.The power transmission takes place in normal operation of the motor vehicle seat on the Belt intake, over the joint, which is assigned to the Gurtaufnahme, continue on the Lanyard and finally over that Joint, which is associated with the seat frame, so that from the seat frame over the Adjustment device for Height and / or Tendency in normal operation forces in the chassis of a motor vehicle can be introduced. When particularly high forces are introduced into the belt take-up are the distance between said first and second joints extendable, so that the distance between the intervening joints, which associated with the locking means are, shortened, so that this engage with a bearing on the chassis counter area can. By using a four-bar linkage, the forces can be initiated centrally, which the connecting means can be loaded directly on train, without absorbing transverse forces would have to be.
Das Verbindungsmittel kann durch eine sehr starke Zugfeder gebildet sein, deren Federkonstante so hoch ist, daß die im Normalbetrieb auftretenden Kräfte nicht zu einer Verlängerung führen, bei der ein Eingriff der Rastmittel mit dem Gegenbereich stattfindet. Der Vorteil bei Verwendung einer Zugfeder ist, daß die Kraftübertragungseinrichtung nach einem Unfall ohne Reparatur und automatisch wieder in seine Ausgangslage, d.h. in seine nicht aktivierte Stellung gebracht werden kann.The Connecting means can be formed by a very strong tension spring be, whose spring constant is so high that the forces occurring in normal operation not to an extension to lead, in which an engagement of the locking means takes place with the counter area. The advantage of using a tension spring is that the power transmission device after an accident without repair and automatically back to his Initial situation, i. be moved to its non-activated position can.
Es ist auch möglich, daß das Verbindungsmittel als starrer Materialabschnitt ausgebildet ist und insb. eine Sollbruchstelle aufweist. Dies hat den Vorteil, daß die Handhabung gegenüber der Montage einer Feder erleichtert sein kann.It is possible, too, that this Connecting means is designed as a rigid material portion and esp. Has a predetermined breaking point. This has the advantage that handling across from the assembly of a spring can be facilitated.
Der Gegenbereich kann, insb. starr, direkt mit dem Chassis eines Kraftfahrzeugs oder auch mit einer längsverschieblichen Schiene einer Längsverstellvorrichtung des Kraftfahrzeugsitzes gelagert sein. Die letztgenannte Ausführungsform hat den Vorteil, daß der Gegenbereich unabhängig von der Längsposition des Kraftfahrzeugsitzes relativ zum Gurtschloß mitführbar ist.Of the Counter area can, esp. Rigid, directly to the chassis of a motor vehicle or with a longitudinally displaceable Rail of a longitudinal adjustment device be stored in the vehicle seat. The latter embodiment has the advantage that the Counter area independent from the longitudinal position the vehicle seat is carried relative to the buckle.
Eine weitere Ausführungsform der Erfindung sieht vor, daß der Gegenbereich bogenförmig ausgebildet ist, so daß bei einer kombinierten Höhen-/Neigungsverstellung eines Sitzrahmens, bei dem der Sitzrahmen bogenförmig um einen Gelenkpunkt bewegt wird, die Kraftübertragungseinrichtung ebenfalls bogenförmig um den Gegenbereich herum geführt werden kann. Hierdurch ist ein Eingriff der Kraftübertragungseinrichtung im Crashfall in allen Höhen-/Neigungspositionen des Sitzrahmens gewährleistet.A another embodiment the invention provides that the Arcuate counter area is formed so that at a combined height / tilt adjustment a seat frame in which the seat frame moves arcuately about a hinge point is the power transmission device also arched guided around the counter area can be. This is an engagement of the power transmission device in the event of a crash in all height / inclination positions ensures the seat frame.
Die Gurtaufnahme kann ein Gurtschloß umfassen und/oder eine Gurtbefestigung. Somit kann die beschriebene Konstruktion auch zweifach, d.h. in Sitzlängsrichtung gesehen links und rechts eines Sitzinsassen vorgesehen sein.The Belt take-up may include a buckle and / or a belt attachment. Thus, the described construction also twice, i. in seat longitudinal direction seen to be provided left and right of a seat occupant.
Nachstehend wird eine bevorzugte Ausführungsform der Erfindung anhand der Zeichnungen im einzelnen beschrieben. Es zeigen:below becomes a preferred embodiment of the invention with reference to the drawings described in detail. It demonstrate:
