Personal mobility vehicle with tiltable seat

A personal mobility vehicle comprising:

• a base;
• a plurality of wheels that are adapted to support the base relative to a supporting surface;
• and
• a seat for supporting an occupant, the seat being supported relative to the base for movement along an arcuate path with a substantially fixed center of rotation, the seat being adjustable such that the center of gravity of the occupant can be positioned substantially coincident with the center of rotation, the center of gravity of the occupant remaining substantially coincident with the center of curvature as the seat is moved along the curve.

A personal mobility vehicle comprising:

• a base;
• a plurality of wheels that are adapted to support the base relative to a supporting surface;
• a seat for supporting an occupant;
• and
• one or more tracks supporting the seat, the one or more tracks serving as a rolling or sliding surface that allows the seat to rotate with respect to the base, the one or more tracks having a constant or substantially constant radius arc with a focal point that is substantially fixed in space, whereby the vehicle is adjustable so that the location of the center of gravity of the occupant can be adjusted to be coincident or near coincident with the focal point, the center of gravity of the occupant remaining coincident or near coincident with the focal point as the seat is moved along the arc.
