leder der Tragarme 40 ist mit seinem einen Ende über einen Lagerbolzen 47 am Sitzrahmen 1 angelenkt und mit seinem anderen Ende mit einem drehbar im Untergestell 2 gelagerten, ein erstes Lagerelement 48 bildenden Rohr fest verbunden. Der obere Hebel 43 jedes Kniehebelpaares ist dem Sitzrahmen 1 mittels eines Lagerbolzens 42 zugeordnet und über einen Kniegelenkzapfen 45 an dem unteren Hebel 44 angelenkt, der mit einem im Untergestell drehbar gelagerten, ein zweites Lagerelement 46 bildenden Rohr fest verbunden ist.leather of the support arms 40 is hinged at one end via a bearing pin 47 on the seat frame 1 and at its other end with a first bearing element 48 rotatably mounted in the subframe 2 forming pipe firmly connected. The upper lever 43 of each toggle lever pair is the seat frame 1 by means assigned to a bearing pin 42 and via a toggle pivot pin 45 on the lower lever 44 articulated, which forms a second bearing element 46 with a rotatably mounted in the underframe Pipe is firmly connected.
An dem ersten Lagerelement 48 ist ein außenverzahntes Zahnsegment 50 festgelegt, mit dem eine mit einer Innenverzahnung versehenen Rastplatte 52 zusammenwirkt. Die Rastplatte 52 ist über eine Langlochführung 55 auf dem ersten Lagerelement 48 und über eine Langlochführung 54 auf einem im Untergestell festgelegten Führungszapfen 53 horizontal verschiebbar geführt. An dem der Langlochführung 55 benachbarten Ende ist an der Rastplatte 52 mittels eines Schwenkzapfens 56 ein Nocken 57 gelagert, dessen erste Nockenfläche 58 mit dem ersten Lagerelement 48 und dessen zweite Nockenflaehe 90 mit einem im Untergestell 2 festgelegten Stütz/apfen 80 zusammenwirkt. An dem Nocken 57 ist an seiner der ersten Nockenflache 58 abgewandten Seite mittels eines Schwenkzapfens 59 eine Schubstange W) schwenkbeweglich gelagert, die an ihrem freien linde einen Schiit/ 61 aufweist, in den ein Stift 62 eingreift, der an einem auf einein im Untergestell 2 angeordneten Bolzen 65 schwenkbar gelagerten, mit einem Handgriff 64 lest verbundenen Hebel 63 festgelegt ist.On the first bearing element 48 is an externally toothed Toothed segment 50 is set with which a locking plate 52 provided with internal teeth cooperates. The locking plate 52 is on the first bearing element 48 via an elongated hole guide 55 and horizontally via an elongated hole guide 54 on a guide pin 53 fixed in the underframe slidably guided. At the end adjacent to the slot guide 55 is on the locking plate 52 by means of a A cam 57 is mounted on the pivot pin 56, the first cam surface 58 of which is connected to the first bearing element 48 and the second cam surface 90 of which cooperates with a support / pin 80 fixed in the underframe 2. On the cam 57 is on its side facing away from the first cam surface 58 by means of a Pivot pin 59 a push rod W) pivotally movable stored, which has a Schiit / 61 on its free linden tree, in which a pin 62 engages, which on a one in the underframe 2 arranged bolt 65 pivotably mounted, reads with a handle 64 connected lever 63 is set.
Auf dem den unteren Hebel 44 des Kniehebelpaares drehfest aufnehmenden zweiten Lagerelement 46 ist ein außenverzahntes Zahnsegment 77 festgelegt, das mit einer Rastklinke 73 zusammenwirkt, die auf einem im Untergestell 2 angebrachten Bolzen 74 schwenkbar gelagert ist. Mit der Rastklinke 73 ist ein Stellteil 72 fest verbunden, das an seinem freien Ende einen Zapfen 71On the second bearing element 46, which receives the lower lever 44 of the toggle lever pair in a rotationally fixed manner, is a externally toothed segment 77 set which cooperates with a latch 73 which is on an im Underframe 2 attached bolt 74 is pivotably mounted. An actuating part 72 is fixed with the latching pawl 73 connected, which has a pin 71 at its free end

An der Kulissenscheibe 66 ist über einen Bolzen 67 eine Schubstange 68 angelenkt, deren freies Finde einen Schlitz 69 aufweist, in den ebenfalls der an r ) which engages in a slot 70 in a link plate 66 rotatably mounted on the second bearing element 46. A push rod 68 is hinged to the link plate 66 via a bolt 67, the free location of which has a slot 69 into which the at

Soll die Lage der Vorderkante des Sitzrahmens 1 geändert werden, so muß hierzu der Handgriff 64 inIf the position of the front edge of the seat frame 1 is to be changed, the handle 64 must for this purpose in
ir> Richtung des Pfeiles A geschwenkt werden. Hierdurch wird über die Schubstange 60 der Nocken 67 gedreht, wodurch seine erste Nockenfläche 58 von dem ersten Lagerelement 48 freikommt. Anschließend legt sich seine zweite Nockenfläche 90 an den Stützzapfen 80 an.i r > in the direction of arrow A. As a result, the cam 67 is rotated via the push rod 60, whereby its first cam surface 58 is released from the first bearing element 48. Then its second cam surface 90 rests against the support pin 80.
Nunmehr wird der Nocken 57 um den Stützzapfen 80 gedreht und bewegt dadurch die Rastplatte 52 in Richtung des Pfeiles f, wodurch die Innenverzahnung der Rastplatte 52 außer Eingriff mit dem außenverzahnten Zahnsegment 50 kommt. Nach erfolgter EinstellungThe cam 57 is now rotated about the support pin 80 and thereby moves the locking plate 52 in the direction of arrow f, whereby the internal toothing of the locking plate 52 disengages from the externally toothed tooth segment 50. After setting

Hierdurch wird über die Schubstange 68 die Kulissenscheibe 66 um das zweite Lagerelement 46 gedreht, wodurch über die aus dem Schlitz 70 und dem Zapfen 61 bestehende Schlitz-Zapfen-Führung der Eingriff zwischen derω of the arrow B can be pivoted. As a result, the link plate 66 is rotated about the second bearing element 46 via the push rod 68, whereby the engagement between the
