The present invention is intended to provide a wheelchair that has a seat height that is adjustable from a standard position to a height at which the users eye level can be the same as that of most standing persons. A gas strut (15, figure 6) is provided to enable the seat to be raised or lowered with the user seated. A main frame 5 is connected to a chassis frame 1 by a front hinge 4 and rear link arm assemblies 19. This allows the main frame to be folded flat (figure 8) to aid storage and transportation. Two independent hand wheels 8 drive the rear wheels 2 via two drive belts 10,11. The hand wheels are connected to the seat 7, and therefore as the seat position is altered the hand wheels remain with the seat thus allowing the wheelchair to be propelled by the user when the seat is in any position. Alternatives to the gas strut and belt drives are discussed. |
