  • Patent number: 5060960
    Abstract: A wheelchair includes a seat panel which is adjustable in a vertical direction upon the manipulation of a jacking assembly beneath the seat panel by an attendant or person other than the wheelchair occupant. During this shifting of the seat panel it is guided by engagement of its corners with four vertical frame members of the wheelchair. Armrests and side portions of the chair frame are pivotable to an out of the way position to form an enlarged planar surface area permitting at least partial reclining of the occupant and ready shifting to a lateral surface such as an adjacent bed. The wheelchair is alternatively supported upon four small wheels, at least two of which caster or, upon two small front wheels and two larger diameter drive wheels thereby offering the most efficient manipulation by either the occupant or an attendant.
