<p>An articulated wheel chair includes front and rear sections (ll, l2) which are pivotally connected together to permit pivoting therebetween about a vertical axis (45). The front section (ll) is provided with a pair of support wheels (20) and the rear section (l2) is provided with a pair of propulsion wheels (4l) driven by an electric motor (6l). A seat (48) for the occupant is pivotally mounted on the rear section (l2) and is connected to the front section (ll) by a link (57) to cause pivoting of the seat (48) in response to articulated pivoting movement between the sections (11, 12). </p> |
