A self-propelled invalid carriage comprises a three-wheeler chassis with two steerable front wheels 1 and a non-steerable rear driving wheel 3, making for good weight distribution with the occupant's seat 56 mounted above the driving wheel, particularly if electric propulsion batteries 20 are mounted in front of the steering wheels. The seat 56 is displaceable in the longitudinal direction of the vehicle and may also be rotatable to facilitate mounting and dismounting by disabled persons. As shown the seat 56 is constituted by a manually movable wheel chair which can be hauled up lowerable ramps 61 by a screw-threaded spindle driven by an electric motor 70. Also described are arrangements for steering, braking etc., for positional adjustment of foot rests, and for removing the front end provided for outdoor travel and replacing it by one more convenient for indoor use. <IMAGE> |
