A collapsible wheelchair and a lift assembly which is permanently mountable in a vehicle and operable for moving the wheelchair and an occupant thereof between the interior and the exterior of the vehicle. The wheelchair includes a chair member and a pair of enlarged rear wheels on the chair member which are operable for movably supporting the rear portion of the chair member on a supporting surface when the chair member is in the erected position thereof. The wheelchair is movable to a collapsed position wherein one of the rear wheels is positioned behind the back portion of the chair member in substantially parallel relation therewith and the other rear wheel is positioned beneath the seat portion of the chair member in substantially parallel relation therewith. When the wheelchair is in the collapsed position, it has a reduced overall profile to enable the wheelchair and an occupant thereof to be effectively moved between the interior and the exterior of a vehicle with the lift assembly.
