Der Fahrzeugsitz weist einen Sitztragrahmen 2 auf, der an einem dem Fahrzeugboden zugeordneten Grundrahmen 18 beidseitig über vordere und hintere Anstellenker 14 abgestützt ist. Das obere Ende jedes Anstellenkers 14 ist über einen Lagerzapfen 15 am Sitztragrahmen 2 angelenkt und sein unteres Ende ist auf einem Zapfen 16 gelagert, der in einem Langloch 17 im Grundrahmen 18 längsverschiebbar geführt ist. Die den vorderen und hinteren Anstellenkern 14 zugeordneten Zapien 16 sind jeweils durch ein Rohr 20 starr miteinander verbunden.Fig. 1 is a side view of the height and tilt adjustable vehicle seat according to the invention and
FIG. 2 shows the section along the line IMI in FIG. 1.
The vehicle seat has a seat support frame 2, which is supported on both sides of a base frame 18 assigned to the vehicle floor via front and rear adjustment arms 14. The upper end of each pivot rod 14 is hinged to the seat support frame 2 via a bearing pin 15 and its lower end is mounted on a pin 16 which is guided in a longitudinally displaceable manner in an elongated hole 17 in the base frame 18. The spigots 16 assigned to the front and rear pitch core 14 are each rigidly connected to one another by a tube 20.

Ί5 An jedem Anstellenker 14 greift über einen Bolzen25 etwa mittig das obere Ende eines Stützhebels 23 an, dessen unteres Ende über durch eine Verbindungsstange miteinander verbundene Lagerzapfen 24 dem Grundrahmen 18 gelenkig zugeordnet ist.5 The upper end of a support lever 23 engages approximately in the middle of each pivot arm 14 via a bolt 25 , the lower end of which is articulated to the base frame 18 via bearing journals 24 connected to one another by a connecting rod.

■50 Auf dem äußeren außerhalb des Langlochs 17 liegenden Ende eines der Zapfen 16 ist eine mit einer Zahnleiste 39 versehene Rastscheibe 38 drehbar gelagert, die von einer am Grundrahmen 18 festgelegten Führungsleiste 18" übergriffen und hierdurch dem Langloch 17 axial verschiebbar aber undrehbar zugeordnet ist.■ 50 On the outer outside of the elongated hole 17 lying end of one of the pins 16 is provided with a toothed strip 39 locking disk 38 is rotatable stored, which overlapped by a fixed on the base frame 18 guide bar 18 "and thereby the Slot 17 is assigned axially displaceable but non-rotatable.

Mit der Zahnleiste 39 wirkt eine Gegenzahnleiste 40 zusammen, die eine der Länge des Langlochs 17 entsprechende Länge aufweist, und an dem ersten ArmA counter-toothed strip 40, which is one of the length of the elongated hole 17, interacts with the toothed strip 39 has a corresponding length, and on the first arm

to 41 eines als Winkelhebel ausgebildeten zweiarmigen Hebels angeordnet ist, der über einer Achse 42 am Grundrahmen 18 schwenkbar gelagert ist und dessen zweiter Arm 44 als Handhebel dient. Die Gegenzahnleiste 40 ist durch eine auf der Achse 42 angeordnete Feder 50 in Eingriffsrichtung mit der Zahnleiste 39 belastet.to 41 of a two-armed lever designed as an angle lever is arranged, which over an axis 42 on Base frame 18 is pivotably mounted and the second arm 44 serves as a hand lever. The counter-tooth bar 40 is loaded in the direction of engagement with the rack 39 by a spring 50 arranged on the axis 42.
