Abstract

Es wird ein Rollstuhl (1) beschrieben, auf dem ein Sitz (1) und an dem zwei Antriebsräder (4) sowie mindestens ein Hinterrad (6) und zwei Vorderräder (10) angeordnet sind, die jeweils über mindestens einen um eine horizontale Achse drehbaren, ein (12) Widerlager aufweisenden Schwenkarm (11a,11b) am Grundkörper angelenkt sind und die aus einer Grundposition in eine angehobene oder aber eine abgesenkte Position bewegbar sind, wobei ein oberer Anschlag (30) zur Begrenzung der Schwenkbewegung des Schwenkarms (11a,11b) vorgesehen ist. Zwischen dem Grundkörper (3) und dem Sitz (2) ist eine Hubeinrichtung (20) vorgesehen, wobei der obere Anschlag (30) mit einem bewegten Bauteil (22,23) der Hubeinrichtung (20) verbunden ist. Dadurch wird der obere Anschlag (30) beim Ausfahren der Hubeinrichtung (20) in seiner Position verändert, so dass der Schwenkbereich für die Vorderräder (10) eingeschränkt wird.

Figure 00000001
A wheelchair (1) is described, on which a seat (1) and on which two drive wheels (4) and at least one rear wheel (6) and two front wheels (10) are arranged, each of which is rotatable about at least one about a horizontal axis , a (12) abutment having pivot arm (11 a, 11 b) are hinged to the base body and which are movable from a basic position to a raised or a lowered position, wherein an upper stop (30) for limiting the pivotal movement of the pivot arm (11 a, 11 b ) is provided. Between the base body (3) and the seat (2), a lifting device (20) is provided, wherein the upper stop (30) with a moving component (22,23) of the lifting device (20) is connected. As a result, the upper stop (30) is changed in its position during extension of the lifting device (20), so that the pivoting range for the front wheels (10) is limited.
