Die Erfindung bezieht sich auf eine Sitzabfederung, insbesondere für Sitzschalen an Traktoren, mit einem Torsionsstab als einstellbarem Federelement, der unter der Sitzschale horizontal quer an einer diesen tragenden Stützplatte angeordnet ist und in den die Torsionskraft mittels einer mittig unter der Stützplatte befindlichen Führungsschwinge eingeleitet wird, deren freies Ende verschiebbar gegenüber dem Fahrzeugboden abgestützt ist, wobei zwischen der Stützplatte und einer Grundplatte ein von zwei gelenkig miteinander verbundenen einerseits an den beiden Seiten der Stützplatte und andererseits an der Grundplatte angelenkten Lenkern gebildetes Knickgestänge vorgesehen ist.The invention relates to a seat suspension, especially for seat shells on tractors, with a torsion bar as an adjustable spring element, the is arranged horizontally transversely under the seat shell on a support plate carrying it and in which the Torsional force is introduced by means of a guide rocker located centrally under the support plate, whose free end is slidably supported with respect to the vehicle floor, with between the support plate and a baseplate one of two hingedly connected to one another on the two Articulated linkage formed on the sides of the support plate and, on the other hand, linked to the base plate links is provided.
Eine Sitzabfederung dieser Art ist bereits Gegenstand eines älteren nicht vorveröffentlichten Patentes. Hierbei ist das freie Ende der Führungsschwinge mittels Rollen in am Fahrzeugboden befestigten U-förmigen Schienen geführt. Durch die Verwendung von Rollen als Führungselemente wird jedoch die ge- ao samte Anordnung sehr störanfällig, da diese einer starken Abnutzung unterliegen und außerdem beispielsweise bei Verschmutzung zum Klemmen neigen.A seat cushioning of this type is already the subject of an older, not previously published patent. Here, the free end of the guide rocker is U-shaped by means of rollers attached to the vehicle floor Rails guided. By using rollers as guide elements, however, the ge ao entire arrangement very prone to failure, as these are subject to heavy wear and tear and also, for example tend to jam when dirty.
Der Erfindung liegt die Aufgabe zugrunde, diese Nachteile zu vermeiden.The invention is based on the object of avoiding these disadvantages.
Die Erfindung ist demgemäß darin zu sehen, daß an dem freien Ende der Führungsschwinge ein Querstück befestigt ist, das an beiden Enden über je einen an sich bekannten Führungslenker mit dem Fahrzeugboden verbunden ist. Diese Führung der Führungsschwinge ist stabiler und weniger verschleißempfindlich als eine Rollenführung, da die Toleranzen wesentlich enger gehalten werden können als zwischen einer Rolle und einer etwa U-förmigen Führungsschiene. Darüber hinaus bringt die erfindungsgemäße Anordnung zwangläufig einen progressiven Federungseffekt, da das freie Ende der Führungsschwinge bei geradliniger Abwärtsbewegung des Sitzes auf einem Kreisbogen schwingt.The invention is accordingly to be seen in the fact that a cross piece at the free end of the guide rocker is attached, which is attached to the vehicle floor at both ends via a guide arm known per se connected is. This guidance of the guide rocker is more stable and less sensitive to wear than a roller guide, as the tolerances can be kept much closer than between one Roller and an approximately U-shaped guide rail. In addition, the arrangement according to the invention brings inevitably a progressive suspension effect, since the free end of the guide rocker is more straight Downward movement of the seat swings on an arc of a circle.
Die Erfindung wird im folgenden an Hand des in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert.The invention is described below with reference to the exemplary embodiment shown in the drawing explained in more detail.
Die erfindungsgemäße Sitzabfederung weist einen unterhalb einer Sitzschale 3 horizontal quer an einer
diese tragenden Stützplatte 4 angeordneten Torsionsstab 2 als Federelement auf, in den die Torsionskraft
über eine Führungsschwingel eingeleitet wird. Die Führungsschwinge 1 erstreckt sich rechtwinklig von
der Torsionsstabmitte weg und trägt an ihrem unteren freien Ende ein Querstück 5, das an seinen beiden

The guide rocker 1 extends at right angles from the center of the torsion bar and carries at its lower free end a cross piece 5, which is attached to both of its seat springs, in particular for seat shells

Enden über je einen Führungslenker 6 mit einer mit dem Fahrzeugboden verbundenen Bodenplatte? gelenkig verbunden ist.Does each end via a guide link 6 with a floor plate connected to the vehicle floor? articulated connected is.
Die Stützplatte 4 ist an ihren beiden gegenüberliegenden Seiten über ein symmetrisches Knickgestänge, das jeweils aus zwei durch ein Gelenk 10 miteinander verbundenen und an den freien Enden an die Stützplatte 4 bzw. die Bodenplatte 7 angelenkten Lenkern 11 und 12 gebildet ist, mit der Bodenplatte 7 verbunden. Die Lenker 11 und 12 bestehen aus Platten, die sich etwa über die Hälfte der Sitzlänge erstrecken. The support plate 4 is on its two opposite sides via a symmetrical articulated linkage, each of two connected to one another by a joint 10 and at the free ends the support plate 4 or the base plate 7 is formed by hinged links 11 and 12, with the base plate 7 tied together. The handlebars 11 and 12 consist of plates that extend over about half the length of the seat.
