Abstract (en)
[origin: WO2009026731A1] The vehicle, for example a stand-up wheelchair, comprises a frame (11) and, arranged on the latter, a seat device (19). On each side of the frame (11), the central wheel (13), which can be driven by a motor (27), and the front wheel (15) are operatively connected to each other by an endless chain (45). The frame (11) has a front part (21) and a rear part (23), which are connected to each other in an articulated manner by way of a joint (25). In the sitting position, the front wheels (15) are not in contact with the ground, which means that they do not obstruct the manoeuvring of the vehicle in a confined space. In the standing position, the front wheels (15) are in contact with the ground, but the central wheels (13) are not. The user, in the standing position, is thus able to turn about the axis of the vehicle, without the central wheels (13) having a blocking action.
