Reciprocating drive motion wheelchair

A reciprocating drive motion wheelchair, comprising:

• a chair frame having a seating portion, a backrest portion, and two hingedly connected footrests wherein the seating area and backrest area intersect orthogonally while the footrests hingedly attach to a leg portion of the chair frame extending from an end of the seating portion opposite the backrest portion;
• a first pair of wheels mounted to a rear portion of the chair frame, wherein each wheel of the first pair of wheels comprises a frame;
• wherein a linear distance between a rear edge of the seat portion and the first pair of wheels is less than a linear distance between a front edge of the seat portion and the first pair of wheels;
• a second pair of wheels having a smaller diameter than the first pair of wheels and rotatably mounted to a forward portion of the chair frame at a point near the hingedly connected footrests wherein the second pair of wheels may freely rotate in a 360-degree fashion relative to the ground surface;
• a pair of drive bars rotatably attached on each side of the chair frame and operably connected to a pair of crank shafts which in turn are operably connected to the first pair of wheels, wherein each drive handle and crank shaft are independently connected to a wheel of the first pair of wheels to allow for operation in unison or independently of each other;
• wherein the crank shafts are rotatably connected to a concentric metal bar attached to the frame of each wheel of the first pair of wheels mounted to the chair frame.
