Abstract
A powered wheelchair has at least two power-steered, driven wheels (15,16,17,18). Preferably, all of the wheels (15,16,17,18) are driven and power-steered such that the wheelchair turns about a point on a transverse axis (X) of the vehicle, and may preferably also pivot on the spot. This turning is preferably achieved by a rotatable steering assembly (1) having steering drive cams (3,4), steering return cams (5,6) and flexible transmission members (13,14).
