Abstract
A manoeuverable, motor-driven wheeled chassis includes a chassis structure carrying two pairs of support wheels (N.sub.1, M.sub.1) separated in the longitudinal direction of the chassis. Between the pairs of support wheels there is a pair of drive wheels (L.sub.1). The chassis structure includes a first frame structure (P.sub.1, 14) carrying a first pair of support wheels (N.sub.1) and the pair of drive wheels (L.sub.1), and a second frame structure (O.sub.1, 10) carrying the second pair of support wheels (M.sub.1) and vertically pivotably connected to the first frame structure (at K). The wheeled chassis is primarily intended for use as a wheelchair (2,4,6).
