A reconfigurable support assembly accessible to a wheel chair bound user for supporting and elevating the user between seated and erect postures. A base frame is configurable to be stationary with foot pads or mobile with roller casters or wheels. Molded foot restraints mount to a base frame or an elevated cross tower to support the feet at selected orientations. A telescoping forward support framework accepts a variety of adjustable accessories, including cushioned knee or leg support assemblies, a chest or upper body support, a table top, arm troughs and manual, hand driven drive assemblies. Adjustable seat and seat back assemblies optionally support pivoting armrests, hip and lateral trunk supports, an extendible back support frame, shoulder retainers, and a head rest. The position of a seat cushion and inclination of the seat back are separately adjustable. In alternative seat assemblies, manual, cable released, gas filled cylinders cooperate with a cantilevered linkage coupled between the seat and base frame to pivot a seat linkage. In another seat assembly, a manually controlled hydraulic lift extends and retracts a seat linkage.

[ What is claimed:] [1.] Support apparatus for supporting and manipulating a user between sitting and standing positions comprising:a) a framework including 1) a plurality of frame members coupled to one another to provide a base and a telescoping upright support frame secured to said base, 2) foot support means secured to said base for supporting the feet of a user; and 3) seat means including a seat for pivotally securing said seat to said base;b) chest support means secured to said support frame for supporting the chest of theuser;c) leg restraint means secured to said support fame for restraining the legs of the user; andd) lift means mounted to said base for pivoting said seat and including a piston mounted and biased for reciprocating movement within a pre-charged cylinder, wherein a latch means is coupled alone the length of the piston and operative at release and latch positions to selectively and directly grip said piston and control the movement of said piston, such that in the release position said piston is free to extend and retract relative to the weight of the user on said seat and in the latch position said piston is prevented from moving, wherein movement of said piston rotates said seat between a transverse orientation to said support frame at a sitting position and a parallel, displaced orientation to said support frame at a standing position, and wherein at said standing position the seat supports the user in engagement with said chest support means and said leg restraint means.
