Abstract
A wheelchair with a tiltable seat locates the tilt fulcrum between 3 and 7 inches from the front edge of the seat pan and between 1 and 4 inches below the surface of the seat pan. This minimizes the elevation of the rider's knees when in a tilted position, and allows for more stability and a shorter wheel base. Manual self-tilting is facilitated by a gas strut arrangement disposed on brackets below the seat pan, and operated by a rider-controlled valve.
