Abstract

The car seat is adjusted for height by cam levers (8a) at the front and rear of the squab, with the setting of the lever altering the spacing between the squab frame and the seat support. In order to provide a sealed mechanism, with no sliding fittings, which may be jam, the levers are pivoted with their upper ends on fixed pivots (4) on the squab frame. These pivots are formed by simple tags (6) welded to the frame. The other ends of the levers are fitted with control knobs (13) mounted in the side flanges (9a) of the seat support, which does not move vertically. The system does not jam normally and has no slots etc. in which the operator could mutilate his fingers.

Die Erfindung bezieht sich auf eine Höhenverstelleinrichtung für Kraftfahrzeugsitze, bei der an einem einem unteren Tragrahmen zugeordneten, ein Sitzpolster tragenden Sitzrahmen zwei hintereinander angeordnete Wellen drehbar gelagert sind, deren äußere Enden exzentrisch mit dem Sitzrahmen zusammenwirken, wobei wenigstens auf einer Sitzlängsseite reib- und/ oder formschlüssig wirkende, den Wellen zugeordnete Feststeller vorgesehen sind und eine der beiden Wellen in Sitzlängsrichtung verschiebbar ist.The invention relates to a height adjustment device for motor vehicle seats, in which on one Associated lower support frame, a seat cushion carrying seat frame two arranged one behind the other Shafts are rotatably mounted, the outer ends of which interact eccentrically with the seat frame, wherein at least on one longitudinal side of the seat frictionally and / or positively acting, assigned to the shafts Locks are provided and one of the two shafts is displaceable in the longitudinal direction of the seat.

Bei den bekannten Höhenverstelleinrichtungen dieser Art (DT-GM 19 87 548) ist der Sitzrahmen zwischen den beiden Seitenwangen des Tragrahmens angeordnet und wirkt mit den Wellen ausschließlich über Exzenterscheiben zusammen. Hierbei ist ein Verstellen der Lage des Sitzrahmens nur durch Drehen der Exzenterscheiben möglich, und der nach oben offene Spalt zwischen den Seitenwangen des Tragrahmens und den Sitzrahmen kann, abgesehen von der hierdurch bedingten raschen Verschmutzung der Verstellteile, zu einem Einklemmen der Finger bzw. von Kleidungsstücken des Sitzbenutzers beim Verstellen des Sitzrahmens führen.In the known height adjustment devices of this type (DT-GM 19 87 548) the seat frame is between arranged on the two side walls of the support frame and acts with the shafts exclusively via eccentric disks together. The position of the seat frame can only be adjusted by turning the eccentric disks possible, and the gap between the side walls of the support frame and the seat frame, which is open at the top can, apart from the resulting rapid soiling of the adjustment parts, to one Entrapment of the user's fingers or clothing when adjusting the seat frame.

Der Erfindung liegt demgegenüber die Aufgabe zugrunde, eine Höhenverstelleinrichtun,g der eingangs genannten Art zu schaffen, bei der bei einfacher Handhabung und einwandfreier Abdeckung der Verstellteile eine Verletzungsgefahr für den Sitzbenutzer oder die Gefahr einer Beschädigung von Kleidungsstükken des Sitzbenutzers nicht gegeben ist.In contrast, the invention is based on the object of providing a height adjustment device of the initially introduced to create the type mentioned, with easy handling and perfect covering of the adjustment parts a risk of injury to the seat occupant or the risk of damage to clothing of the seat occupant is not given.

Die Erfindung erreicht dies dadurch, daß die Wellen mit am Sitzrahmen drehbar gelagerten Schwenkzapfen über Laschen fest verbunden sind und der gegenüber dem Tragrahmen in an sich bekannter Weise unter anhebender Federwirkung stehende Siitzrahmen den Tragrahmen mittels Seitenwangen übergreift.The invention achieves this in that the shafts have pivot pins rotatably mounted on the seat frame Are firmly connected via tabs and the opposite of the support frame in a known manner below lifting spring action, the seat frame engages over the support frame by means of side walls.

Im folgenden ist die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispieles näher erläutert. Es zeigtThe invention is described in greater detail below with the aid of an exemplary embodiment shown in the drawing explained. It shows

Fig. 1 eine Seitenansicht eines mit der erfindungsgemäßen Höhenverstelleinrichtung ausgerüsteten Kraftfahrzeugsitzes undFig. 1 is a side view of one with the invention Height adjustment device equipped motor vehicle seat and

Der Kraftfahrzeugsitz weist einen Tragrahmen 1 auf, der auf einem fahrzeugfesten Teil angeordnet ist.The motor vehicle seat has a support frame 1 which is arranged on a part fixed to the vehicle.

Auf dem Tragrahmen 1 ist in einem Lagerauge 6 eine vordere Welle 4 und in einer ein in Sitzlängsrichtung verlaufendes Langloch bildenden Lageröse 7 eine hintere Welle 5 drehbar gelagertOn the support frame 1 there is a front shaft 4 in a bearing eye 6 and one in the longitudinal direction of the seat running elongated hole forming bearing eye 7 a rear shaft 5 rotatably mounted

An den einen Enden der beiden Wellen 4 und 5 sind Laschen 8a aus Blech befestigt und an den anderen Enden ebenfalls aus Blech bestehende Laschen 86.At one end of the two shafts 4 and 5 tabs 8a made of sheet metal are attached and at the other Ends also made of sheet metal tabs 86.

Die freien Enden der Laschen 86 sind mittels Schwenkzapfen 10a drehbar in der einen Seitenwange 96 eines ein Sitzpolster 3 tragenden Sitzrahmens 2 gelagert, dessen andere Seitenwange 9a die freien Enden der Laschen 8a über Schwenkzapfen 10a drehbar aufnimmt. Der Abstand der beiden, untere Abwinkelungen 14a bzw. 146 aufweisenden und aus am Sitzrahmen 2 befestigten Blechen bestehenden Seitenwangen 9a und 96 ist hierbei größer als die Breite des Tragrahmens 1, so daß die Seitenwangen 9a und 96 den Tragrahmen 1 übergreifen. Auf den Schwenkzapfen 10a sind an den einander zugekehrten Flächen der Seitenwange 9a und der Lasche 8a befestigte Reib- oder Zahnscheiben 11 gelagert, zwischen denen eine sie in Richtung ihrer Freigabestellung belastende Feder 12 angeordnet ist. Das nach außen ragende eine Ende jedes Lagerzapfens 10a ist mit einem Gewinde versehen, auf daß ein Drehgriff 13 aufgeschraubt ist, dessen innere Stirnseite mit der Außenseite der Seitenwange 9a zusammenwirkt. Außerdem ist auf jeder Welle 4 bzw. 5 wenigstens eine Schiingfeder 15 angeordnet, deren eines Ende 16 mit der zugehörigen Welle 4 bzw. 5 verbunden ist und deren anderes Ende 17 am Tragrahmen 1 abgestützt ist.The free ends of the tabs 86 can be rotated in one side wall by means of pivot pins 10a 96 of a seat frame 2 carrying a seat cushion 3, the other side cheek 9a of which is the free Receives ends of the tabs 8a via pivot pins 10a rotatably. The distance between the two, lower bends 14a or 146 having side cheeks 9a and consisting of metal sheets attached to the seat frame 2 and 96 is greater than the width of the support frame 1, so that the side panels 9a and 96 support the support frame 1 overlap. On the pivot pin 10a are on the mutually facing surfaces of the side cheek 9a and the bracket 8a mounted friction or toothed disks 11, between which one they in the direction of their Release position loading spring 12 is arranged. The outwardly protruding one end of each journal 10a is provided with a thread, so that a rotary handle 13 is screwed, its inner end face cooperates with the outside of the side wall 9a. In addition, there is at least one on each shaft 4 or 5 Coil spring 15 arranged, one end 16 of which is connected to the associated shaft 4 or 5 and whose the other end 17 is supported on the support frame 1.

In der Gebrachsstellung des Kraftfahrzeugsitzes sind die Wellen 4 und 5 und damit die Laschen 8a und 86 durch die durch den fest aufgeschraubten Drehgriff 13 in Eingriff miteinander gehaltenen Reib- oder Zahnscheiben 11 in ihrer eingestellten Lage gesichert Soll die Lage des Sitzrahmens 2 verändert werden, so ist es notwendig, einen oder beide Drehgriffe 3 zu lösen, wodurch die Feder 12 die Reib- oder Zahnscheiben Il außer Eingriff miteinander bringt, so daß nunmehr entweder durch die Schlingfeder 15 der Sitzrahmen 2 angehoben oder durch das Gewicht des Sitzbenutzers abgesenkt werden kann.The shafts 4 and 5 and thus the tabs 8a and 86 are in the broken position of the motor vehicle seat by the friction or toothed disks held in engagement with one another by the screwed-on rotary handle 13 11 secured in its set position If the position of the seat frame 2 is to be changed, it is necessary to loosen one or both rotary handles 3, whereby the spring 12, the friction or toothed disks Il brings out of engagement with each other, so that now either by the wrap spring 15 of the seat frame 2 can be raised or lowered by the weight of the seat occupant.

Zur Aufnahme der Reib- und Zahnscheiben 11 sind zweckmäßig wenigstens die Schwenklaschen 86 auf ihrem in der Seitenwange 96 gelagerten Ende verbreitert. Ferner ist aus F i g. 2 ersichtlich, daß die Seitenwangen 9a und 96 als am Sitzrahmen 2 befestigte Bleche ausgebildet sind. In der höchsten Stellung des Sitzrahmens 2 legen sich die unteren Abwinkelungen 14a bzw. 146 der Seitenwangen 9a und 96 gegen die Enden der Wellen 4 und 5.To accommodate the friction and toothed disks 11, at least the pivoting brackets 86 are expediently on its end supported in the side cheek 96 is widened. Furthermore, from FIG. 2 it can be seen that the Side cheeks 9a and 96 are designed as metal sheets attached to the seat frame 2.
