an elongate rod coupled to and positioned between the first chair attachment assembly and the second chair attachment assembly; and

a pair of wheel attachment assemblies, wherein a first wheel attachment of the pair of wheel attachment assemblies is coupled to a distal end of the elongate rod, and a second wheel attachment assembly of the pair of wheel attachment assemblies is coupled to a proximal end of the elongate rod, and wherein each of the first and second wheel attachment assemblies defines an internal cavity;

the first and second wheel attachment assemblies each comprise a first plate positioned on a first side of the elongate rod and a second plate positioned on a second side of the elongate rod such that the plates are spaced a predetermined distance and an inner surface of the first plate faces an inner surface of the second plate;

a pair of receivers each having a proximal end and an opposed distal end, wherein a bore is defined in the distal end of each receiver, the bore configured to rotatingly engage an axle of a rear wheel of the wheelchair, wherein the proximal end of each receiver of the pair of receivers is positionable in the internal cavity of the pair of wheel attachment assemblies, wherein each receiver is slidable in the internal cavity about and between a first position in which the rear wheels are each in a first wheel position that is substantially perpendicular to a surface upon which the wheelchair is positioned, and a second position in which the rear wheels are in a second wheel position that is different than the first wheel position; and

a plurality of locking pins, each locking pin configured to secure a receiver to the bracket assembly in a desired position.

2. The wheelchair of claim 1 , wherein the first wheel attachment assembly is slidingly, rotatably coupled to the distal end of the elongate rod, and the second wheel attachment assembly is slidingly, rotatably coupled to the proximal end of the elongate rod.

3. The wheelchair of claim 1 , further comprising at least one slot defined in the inner surface of the first plate and the inner surface of the second plate, wherein the at least one slot is configured to slidingly receive a portion of the receiver therein.

4. The wheelchair of claim 3 , wherein the at least one slot is arcuate in shape.

5. The wheelchair of claim 1 , wherein the first plate of each wheel attachment assembly is rotatable about a first attachment position, in which the first plate of each attachment assembly is substantially perpendicular to the surface on which the wheelchair rests, and a second attachment position, in which the first plate of each attachment assembly is at an angle relative to the surface on which the wheelchair rests.

6. The wheelchair of claim 1 , wherein the first and second chair attachment assemblies are adjustable so that the elongate rod is positioned a predetermined distance from the frame.

7. The wheelchair of claim 1 , wherein in the first wheel position, a top portion of a first rear wheel is in a first vertical plane, and in the second wheel position, the top portion of the first rear wheel is in the first vertical plane.

8. The wheelchair of claim 1 , wherein in the first wheel position, the frame of the wheelchair is a first distance from the ground upon which the wheelchair sits, and in the second wheel position, the frame of the wheelchair is the first distance from the ground.

9. A system for converting a conventional wheelchair having a frame and two rear wheels into an adjustable camber wheelchair, the system comprising:

a bracket assembly coupled to and fixed relative to a frame of the wheelchair, the bracket assembly comprising:

a pair of chair attachment assemblies, wherein a first chair attachment assembly of the pair of chair attachment assemblies is coupled to the frame on a first side of the wheelchair, and wherein a second chair attachment assembly of the pair of chair attachment assemblies is coupled to the frame on a second side of the wheelchair that is opposed to the first side;

an elongate rod coupled to and positioned between the first chair attachment assembly and the second chair attachment assembly; and

a pair of wheel attachment assemblies, wherein a first wheel attachment of the pair of wheel attachment assemblies is coupled to a distal end of the elongate rod, and a second wheel attachment assembly of the pair of wheel attachment assemblies is coupled to a proximal end of the elongate rod, and wherein each of the first and second wheel attachment assemblies defines an internal cavity;

the first and second wheel attachment assemblies each comprise a first plate positioned on a first side of the elongate rod and a second plate positioned on a second side of the elongate rod such that the plates are spaced a predetermined distance and an inner surface of the first plate faces an inner surface of the second plate;

a pair of receivers each having a proximal end and an opposed distal end, wherein a bore is defined in the distal end of each receiver, the bore configured to rotatingly engage an axle of a rear wheel of the wheelchair, wherein the proximal end of each receiver of the pair of receivers is positionable in the internal cavity of the pair of wheel attachment assemblies, wherein each receiver is slidable about and between a first position in which the rear wheels are each in a first wheel position that is substantially perpendicular to a surface upon which the wheelchair is positioned, and a second position in which the rear wheels are in a second wheel position that is different than the first wheel position; and

a plurality of locking pins, each locking pin configured to secure a receiver to the bracket assembly in a desired position.

10. The system of claim 9 , wherein the first wheel attachment assembly is slidingly, rotatably coupled to the distal end of the elongate rod, and the second wheel attachment assembly is slidingly, rotatably coupled to the proximal end of the elongate rod.

11. The system of claim 9 , further comprising at least one slot defined in the inner surface of the first plate and the inner surface of the second plate, wherein the at least one slot is configured to slidingly receive a portion of the receiver therein.

12. The system of claim 11 , wherein the at least one slot is arcuate in shape.

13. The system of claim 9 , wherein the first plate of each wheel attachment assembly is rotatable about a first attachment position, in which the first plate of each attachment assembly is substantially perpendicular to the surface on which the wheelchair rests, and a second attachment position, in which the first plate of each attachment assembly is at an angle relative to the surface on which the wheelchair rests.
