Wird der Griff 9 in der Nut 10 verschoben, so bewegen die Schubstangen 8 das Kniehebelpaar 4, 5, 6, 7, wodurch auch der Rahmen 1 gegen den Rahmen 3 bewegt wird. Der Griff 9 läßt sich so weit gegen einen Anschlag verschieben, daß die Kniehebel überknicken und so eine selbsttätige Arretierung für die ausgeschwenkte Lehne ergeben. Bei Zurückführung des Griffes 9 wird auch die Lehne in die senkrechte Lage zurückgeführt. In dieser Lage kann die Lehne durch beliebige Schnepper arretiert werden.On the movable frame 1, which is attached to the fixed frame 3 by means of hinges a is, a link 4 is attached. These handlebars are each via a swivel joint S with each connected to another handlebar 6 which are rotatably attached to the fixed frame 3. The links 4 and 6 form two movable toggle levers, the movable and the fixed Connect frames together. A push rod 8 engages each of the knee joints 5, which are articulated to one another by a handle 9. This handle 9 is in one Groove 10 guided in the fixed frame 3. If the handle 9 is moved in the groove 10, move it the push rods 8 the toggle pair 4, 5, 6, 7, whereby the frame 1 against the Frame 3 is moved. The handle 9 can be moved so far against a stop that bend over the knee lever and thus an automatic locking for the swiveled out Surrender.
