Abstract
Sitzlehnenverstellung für einen Fahrzeugsitz gekennzeichnet durch ein axial verschiebbares Konturteil, bevorzugt ein Zahnrad, welches formschlüssig in eine Gegenkontur, bevorzugt eine Gegenverzahnung, eingreift und zur Betätigung axial verschoben wird.Seat back adjustment for a vehicle seat characterized by an axially displaceable contour part, preferably a gear which positively engages in a mating contour, preferably a counter-toothing, and is axially displaced for actuation.
Description
Sitzlehnenverstellungen sind in vielfachen Ausführungen bereits bekannt, zum Beispiel durch Verstellung mittels Gasdruckfeder oder durch schraubbare oder schweißbare Beschläge mit innenliegender Mechanik.Seat recliners are in multiple versions already known, for example by adjustment by means of gas spring or by screwable or weldable fittings with internal Mechanics.
Aufgabe der Erfindung ist es auf eine möglichst einfache Art eine einfach zu bedienende Verstellung und eine form- und kraftschlüßige Arretierung der Sitzlehne zu erreichen, die hohe Kräfte, zum Beispiel Gurtkräfte des Gurtumlenkpunktes der Rückenlehne aufnehmen kann.task The invention is as possible simple way an easy-to-use adjustment and a form-fitting and force-locking the seat back to achieve the high forces, for example belt forces of the Gurtumlenkpunktes the backrest can record.
Diese Aufgabe wird durch die nachfolgend beschriebene Sitzlehnenverstellung gelöst.These Task is by the seat back adjustment described below solved.
Die Welle (a) ist der Drehpunkt einer Rückenlehne eines Fahrzeugsitzes. Auf der Welle ist das Seitenteil Lehne (b) drehbar gelagert. Der verzahnte Ring (c) ist mit dem Seitenteil Lehne (b) fest verbunden. Das Seitenteil II unverzahnt (d) sowie das Seitenteil I verzahnt (e) sind am Sitzrahmen (f) befestigt.The Shaft (a) is the fulcrum of a backrest of a vehicle seat. On the shaft, the side part backrest (b) is rotatably mounted. Of the toothed ring (c) is firmly connected to the side part back (b). The side part II without teeth (d) and the side part I interlocked (e) are attached to the seat frame (f).
In der Verzahnung des Seitenteiles (e) kann sich das Zahnrad (g) axial bewegen. Das Zahnrad (g) ist auf der Welle (a) radial beweglich gelagert, ist aber axial zum Beispiel durch Wellensicherungsringe (h) gesichert. In der gezeichneten Stellung (Hebel (i) unten) ist das Zahnrad (g) mit der Gegenverzahnung des Ringes (c) im Eingriff. Die Sitzlehnenverstellung ist arretiert. Wird nun der Hebel (i) nach oben, gegen die Federkraft der Zugfeder (j) gezogen, wird durch die Kontur der Führung (k) die Welle axial nach außen bewegt. Das Zahnrad (g) wird aus der Gegenverzahnung des Ringes (c) gezogen und die Lehne kann verstellt werden. Wird der Hebel (i) nun wieder freigegeben wird durch die Zugfeder (j) der Hebel (i) wieder nach unten gezogen. Die Welle mit dem Zahnrad (g) wird somit axial wieder nach innen verschoben und die Sitzlehnenverstellung ist wieder arretiert. Die Erfindung ist für einen Einzelsitz und für Sitzbänke verwendbar. Bei Sitzbänken können 2, 3 oder mehrere Sitzlehnenverstellungen mit einer gemeinsamen Welle und mit einem Hebel (i) synchron betätigt werden.In the toothing of the side part (e), the gear (g) can axially move. The gear (g) is radially movable on the shaft (a) stored, but is axially, for example, by shaft securing rings (h) secured. In the drawn position (lever (i) below) is the gear (g) with the counter teeth of the ring (c) in engagement. The seat back adjustment is locked. Will now the lever (i) upwards, pulled against the spring force of the tension spring (j), by the Contour of the leadership (k) the shaft axially outward emotional. The gear (g) is made of the counter teeth of the ring (c) pulled and the backrest can be adjusted. Will the lever (i) is released again by the tension spring (j) of the lever (i) pulled down again. The shaft with the gear (g) becomes thus axially shifted back in and the seat back adjustment is locked again. The invention can be used for a single seat and for benches. With benches can 2, 3 or more seat back adjusters with a common shaft and operated synchronously with a lever (i).
