Description
Fahrersitz für Kraftwagen, insbesondere Omnibusse u. dgl. Die Erfindung bezieht sich auf einen Fahrersitz für Kraftwagen, insbesondere Omnibusse und ähnliche Fahrzeuge, bei welchen ein verhältnismäßig häufiger Wechsel des Fahrers vorkommt, wobei die Höhenlage des Sitzpolsters den verschiedenen Körpergrößen der Fahrer angepaßt werden muß. Es sind bereits höhenverstellbare Sitze bekannt, bei welchen das Sitzpolster auf teleskopartig ausziehbaren und in verschiedenen Höhenlagen einstellbaren Füßen ruht. Zur Vermeidung der dieser Bauart anhaftenden Nachteile wurden auch bereits Sitze gebaut, deren Sitzpolster lose auf Querstangen aufgelegt ist, die in stufenförmigen Rasten verstellt werden können, welche durch entsprechende Aussparungen von am Sitzgestell starr befestigten Längsschienen gebildet werden. Zum Wechsel der Höhenlage des Sitzes muß hierbei das Sitzpolster zunächst aus seinem Rahmen angehoben werden, damit die Querstangen über die Trennwände der hintereinanderliegenden Rasten hinweg bewegt und in die nächste oder übernächste Rast eingesenkt werden können. Auch sind hierbei die Seitenwände des Rahmens durch die Rastschlitze durchbrochen, was leicht zu Störungen Anlaß geben kann.Driver's seat for motor vehicles, in particular buses and the like. The invention relates to a driver's seat for motor vehicles, especially buses and the like Vehicles in which there is a relatively frequent change of driver, the height of the seat cushion being adapted to the various body sizes of the driver must become. There are already height-adjustable seats known in which the seat cushion on telescopic feet that can be adjusted to different heights rests. In order to avoid the disadvantages inherent in this type of construction, Seats built, the seat cushion is placed loosely on cross bars, which are in step-shaped Notches can be adjusted, which through corresponding recesses on the seat frame rigidly attached longitudinal rails are formed. To change the height of the seat the seat cushion must first be lifted out of its frame so that the Cross bars moved over the partition walls of the notches lying one behind the other and can be sunk into the next or the next rest. Also are here the side walls of the frame perforated by the locking slots, which can easily lead to disruptions Can give occasion.
Bekannt ist auch ein Fahrersitz, bei welchem die Querstangen in übereinanderliegenden kurvenförmigen Schlitzen eingerastet werden können, die in zahnartig ausgesparten seitlichen Rastplatten vorgesehen sind. Da hierbei aber keine stetige Führung der Querstangen beim Anheben oder Absenken vorhanden ist, ist eine Verstellung der Höhenlage des Sitzes, solange dieser in seinem Rahmen verbleibt, nur dadurch möglich, daß die Querstangen an beiden Enden zugleich angehoben werden, was erhebliche Unbequemlichkeiten mit sich bringt.A driver's seat is also known in which the crossbars lie one above the other curved slots that can be snapped into place in tooth-like recessed lateral locking plates are provided. But here there is no continuous There is guidance of the cross bars when raising or lowering, is an adjustment the height of the seat, as long as it remains in its frame, only by doing this possible that the cross bars are raised at both ends at the same time, which is considerable Brings inconvenience.
Gegenstand der Erfindung ist ein Fahrersitz, insbesondere für Kraftomnibusse u. dgl., bei welchem gleichfalls das Sitzpolster innerhalb eines Rahmens auf in kurvenförmigen Führungen in verschiedener Höhenlage einstellbaren Querstangen aufliegt, wobei aber die Nachteile der bekannten Anordnungen dadurch vermieden sind, daß die Stangenenden innerhalb je einer geschlossenen und ununterbrochenen kreisbogenförmigen Kurvenführung stetig verstellbar sind und in den Kurvenenden eingerastet -werden können. Da die Stangen hierbei dauernd in der Bogenführung abgestützt sind, ist es ohne Schwierigkeiten möglich, sie von einer Seite des Sitzes aus mittels eines Hebels zu verstellen, -wobei sie z-wangläufig auf beiden Seiten in gleicher Höhe geführt werden, so daß eine Schrägstellung der Stangen nicht möglich ist. Ein Anheben des Sitzes aus dem Rahmen ist hierbei nicht erforderlich. Vorzugsweise sind erfindungsgemäß nahe unter dem vorderen und hinteren Ende des Sitzpolsters je zwei Querstangen angeordnet, die mit ihren beidseitigen Enden so in den Führungsnuten geführt sind, daß in der höchsten Lage und in der Mittellage des Sitzpolsters je nur eine der beiden Stangen eines Querstangenpaares zum Tragen kommt, wogegen in der tiefsten Lage beide Stangen in gleicher Ebene liegen und das Sitzpolster tragen. Die beiden Führungsnuten sind hierbei kreisbogenförmig über einen Scheitelpunkt hinweggeführt, so daß die Stangen unterhalb dieses Punktes zuverlässig in der höchsten bzw. mittleren Stellung einrasten können. Beide Stangen eines Tragstangenpaares sind durch einen bequem von außen verstellbaren Hebel derart miteinander verbunden, daß sie sich stets in gegenläufigem Sinne bewegen und in der tiefsten Stellung des Polsters von selbst in der gleichen Ebene einstellen.The invention relates to a driver's seat, in particular for buses and coaches and the like, in which also the seat cushion within a frame on in curved guides at different heights adjustable crossbars, but the disadvantages of the known arrangements are avoided in that the Rod ends within each a closed and uninterrupted circular arc-shaped Curve guidance are continuously adjustable and are locked in the ends of the curve can. Since the rods are constantly supported in the arch guide, is it is possible without difficulty to do so from one side of the seat by means of a Lever to adjust, -wherein they z-wanggang on both sides at the same height be guided so that an inclined position of the rods is not possible. A lifting the seat out of the frame is not necessary here. Preferably are according to the invention two crossbars each arranged near the front and rear end of the seat cushion, which are guided with their ends on both sides in the guide grooves that in the highest position and in the middle position of the seat cushion only one of the two bars a pair of cross bars comes into play, whereas in the lowest position both bars lie on the same level and wear the seat cushion. The two guide grooves are in this case guided away in the shape of a circular arc over an apex, so that the rods Reliably click into place below this point in the highest or middle position can. Both rods of a pair of support rods are easily accessible from the outside adjustable lever connected so that they are always in opposite directions Moving senses and in the lowest position of the cushion by itself in the same Set level.
Außer einer gleichmäßigen Höhenverstellung des Sitzpolsters ist bei dieser Anordnung auch eine Schrägstellung mit Neigung von vorn nach hinten und umgekehrt möglich.Apart from an even height adjustment of the seat cushion is at this arrangement also has an inclination with an inclination from the front to the rear and vice versa possible.
Ein Ausführungsbeispiel eines Fahrersitzes für einen Kraftomnibus gemäß der Erfindung ist in der Zeichnung in schematischer Form dargestellt.An embodiment of a driver's seat for a bus according to the invention is shown in the drawing in schematic form.

Mit i ist die Seitenwand eines an sich bekannten rechteckigen Blechrahmens bezeichnet, in welchem das mit gestrichelten Linien angedeutete Sitzpolster 2 geführt ist. Das Sitzpolster liegt vorn und hinten lose auf den Ouerstangen 3, 4 zweier Stangenpaare auf; die beiden Stangen jedes Paares sind durch laschenartige Hebel 5 miteinander verbunden, die mittels eines seitlich außen an dem Sitzrahmen angebrachten, bequem zugänglichen Handgriffes 6 um eine Achse oder einen Zapfen 7 verschwenkt werden können, wobei sich die beiden Stangen in :gegenläufigem Sinne bewegen.With i is the side wall of a known rectangular sheet metal frame denotes, in which the seat cushion 2 indicated by dashed lines is guided is. The seat cushion lies loosely at the front and back on the crossbars 3, 4 of two Pairs of rods on; the two rods of each pair are through tab-like levers 5 connected to each other, which are attached to the outside of the seat frame by means of a easily accessible handle 6 pivoted about an axis or a pin 7 can be, whereby the two rods move in opposite directions.
Auf der Innenseite der beiden i sind flache Blech- oder Formstücke 8 befestigt, die je zwei kreisbogenförmige Schlitze gh und io aufweisen, welche in entgegengesetzter Richtung untereinander verlaufen. In diesen Schlitzen sind die Enden der Tragstangen 3 und 4 derart geführt, daß bei einer Verstellung des Hebels 5 die eine der beiden Stangen gehoben, die andere gesenkt wird, wobei die Stangen entweder gemäß Fig.4 in die unterhalb der Scheitelhöhe der Schlitze liegenden Nutenden einrasten oder gemäß Fig. :2 in gleicher Ebene liegen, in welcher Lage sie durch das Gewicht des Sitzpolsters festgehalten werden.On the inside of the two i are flat pieces of sheet metal or shaped pieces 8 attached, each having two arcuate slots gh and io, which run in the opposite direction to each other. In these slots are the ends of the support rods 3 and 4 guided such that when the Lever 5 lifts one of the two rods, the other is lowered, with the Rods either as shown in FIG Snap in slot ends or, as shown in FIG.: 2, lie in the same plane, in which position they are held in place by the weight of the seat cushion.
