AbstractAn upper front annular frame and a lower annular frame have pivotally connected front portions, and a seat overlies the frames and has a rear portion pivotally connected to a rear portion of the upper frame. A pair of scissor linkages are connected to corresponding opposite side portions of the frames and have forwardly projecting arms supporting rollers engaging a bottom surface of the seat. A motor driven screw jack is supported by a bracket mounted on one side portion of the lower frame and is connected to tilt the upper frame between a horizontal position adjacent the lower frame and an elevated inclined position while the scissor linkages automatically move the seat between a horizontal position and an inclined elevated position projecting forwardly of the frames.
