(7a;7b; 7c) um eine zur horizontalen, ersten Achse (3) parallele, zweite Achse (7d;7e;7f) verschwenkbar am Sitzrahmen (1; 1') gelagert ist, ferner mit einem Gurtschloß (8) eines Sicherheitsgurtes, das über einen Gurtschloßträger (8a) am Sitzrahmen (1;1') befestigt ist, dadurch gekennzeichnet, daß der Gurtschloßträger (8a), zumindest mittelbar, mit dem Rastglied (7a; 7b;7c) für dessen Verschwenken verbunden ist und das mindestens einfach vor gesehene Rastglied (7a;7b;7c) mit einem Rastgliedträger (7g;7g';7g") verbunden und schwenkbar um eine von der ersten (3) und der zweiten Achse (7d;7e; 7f) beabstandete und dazu parallele, dritte Achse (7h;7i;7k) gelagert ist und daß der Gurtschloßträger (8a) an dem Rastgliedträger (7g; 7g'; 7g") befestigt ist, der um die horizontale, erste Achse (3) zwischen einer mit einer Eingriffsstellung des Rastgliedes (7a;7b; 7c) korrespondierenden Stellung und einer mit einer Freigabestellung des Rastgliedes (7a;7b;7c) korrespondierenden Endstellung verschwenkbar gelagert ist.Motor vehicle seat with a seat frame (1; 1 ') and a seat height adjustment device, which has two body-mounted, pivotable about a horizontal, first axis (3) handlebars that can be pivoted to adjust the height of the seat in different inclination positions, with a drive device provided only on one side pivoting a handlebar, the two links being connected to one another in a rotationally fixed manner by means of a connecting tube (6), with a side on the opposite side of the drive device. between the seat frame (1; 1 ') and the adjacent link (5) effective locking device (7) which has a toothing (5a) which is concentric with the horizontal axis (3) and into which a locking element (7a; 7b; 7c) is exceeded when a predetermined acceleration is exceeded ) engages in such a way that the pivoting position of the handlebar (5) is fixed relative to the seat frame (1; 1 '), the locking member. (7a; 7b; 7c) is mounted on the seat frame (1; 1 ') so as to be pivotable about a second axis (7d; 7e; 7f) parallel to the horizontal first axis (3), furthermore with a belt buckle (8) of a seat belt, which is attached to the seat frame (1; 1 ') by means of a belt buckle carrier (8a), characterized in that the belt buckle carrier (8a) is connected, at least indirectly, to the latching member (7a; 7b; 7c) for pivoting it, and at least simply before seen locking member (7a; 7b; 7c) connected to a locking member carrier (7g; 7g '; 7g ") and pivotable about a third from the first (3) and the second axis (7d; 7e; 7f) spaced apart and parallel thereto Axis (7h; 7i; 7k) is mounted and that the belt buckle carrier (8a) is fastened to the locking member carrier (7g; 7g '; 7g "), which is about the horizontal, first axis (3) between an engaged position of the locking member ( 7a; 7b; 7c) corresponding position and an end position corresponding to a release position of the locking member (7a; 7b; 7c) lung is pivotally mounted.
Description
Die Erfindung betrifft einen Kraftfahrzeugsitz nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a motor vehicle seat the preamble of claim 1.
Bei einem Kraftfahrzeugsitz der als
bekannt vorausgesetzten Art (
Die durch die Masse des Rastgliedes bestimmte Trägheitskraft ist nur gering wegen des nur begrenzten Einbauraums und wegen der Vorgabe, Kraftfahrzeugsitze möglichst leicht auszubilden. Die Größe der Trägheitskraft ist unabhängig von dem von der jeweiligen Benutzungssituation abhängigen Belastungszustand des Kraftfahrzeugsitzes. Damit ist auch die Verriegelungskraft des Lenkers im Crashfall unabhängig von der Benutzungssituation.By the mass of the locking member certain inertia is only small because of the limited installation space and because of the Guideline, motor vehicle seats if possible easy to train. The size of the inertia is independent from the load condition depending on the respective usage situation of the motor vehicle seat. This is also the locking force of the Independently in the event of a crash from the usage situation.
Es ist auch bereits bekannt (
Schließlich ist es auch bekannt,
das Untergestell eines Fahrzeugsitzes über vordere und hintere Schwenkstützen an
der Oberschiene einer Längsverstellschiene
anzulenken (
Ausgehend von dem eingangs erwähnten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, einen Kraftfahrzeugsitz der als bekannt vorausgesetzten Art so auszubil den, daß im Crashfall die Verriegelungsvorrichtung mit hoher Kraft und in Abhängigkeit vom Benutzergewicht blockiert wird.Based on the status mentioned at the beginning The object of the invention is to provide a motor vehicle seat of the type presumed to be known so that in the event of a crash Locking device with high force and depending is blocked by user weight.
Die Lösung dieser Aufgabe erfolgt mit den Merkmalen des Patentanspruchs 1.This task is solved with the features of claim 1.
Über den Sicherheitsgurt kann eine von der Belegung des Sitzes abhängige Verriegelung des nicht angetriebenen Lenkers der Sitzhöhenverstellung erfolgen. Ein unbenutzer Kraftfahrzeugsitz muß nicht verriegelt werden. Ein von einem schweren Sitzbenutzer belasteter Fahrzeugsitz wird mit entsprechend hoher Anpreßkraft verriegelt.about The seat belt can be locked depending on the occupancy of the seat of the non-driven handlebar of the seat height adjustment. On unused car seat does not have to be locked. A burdened by a heavy seat user Vehicle seat is locked with a correspondingly high contact pressure.
Bevorzugte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.Preferred embodiments of the invention result itself from the subclaims.
Bei einer bevorzugten Ausführungsform der Erfindung wird ein Teil der auf den Sicherheitsgurt bei einem Front-Crash ausgeübten Rückhaltekraft über den Rastgliedträger in den Lenker eingeleitet und belastet daher den Sitzrahmen nicht. Bei einer weiteren bevorzugten Ausführung mit gleichmäßig über den Umfang der umlaufenden Verzahnung verteilten Rast gliedern wird die Verriegelungskraft querkraftfrei auf den Lenker übertragen.In a preferred embodiment the invention becomes part of the seat belt at a Front crash wielded Retention force over the Locking member carrier introduced into the handlebar and therefore does not strain the seat frame. In a further preferred embodiment with a uniform circumference The locking force is divided by the circumferential teeth transfer to the handlebars without lateral force.
Nachstehend werden drei bevorzugte Ausführungsformen der Erfindung anhand der Zeichnungen im einzelnen beschrieben. Es zeigen:Three are preferred below embodiments the invention with reference to the drawings described in detail. It demonstrate:
In den Zeichnungen sind gleiche Teile mit den gleichen Bezugszeichen versehen, die sich im Bedarfsfall durch Hochstriche voneinander unterscheiden.The same parts are in the drawings provided with the same reference numerals, which if necessary distinguish from each other by means of dashes.
