         2 . The wheelchair seat back assembly of  claim 1  wherein the mounting hardware and the seat back are dimensioned and configured to permit the height of the seat back to be adjusted independently of the mounting hardware location on the wheelchair. 
     
     
         3 . The wheelchair seat back assembly of  claim 1  wherein the mounting hardware comprises a mounting pin configured to be mounted in relation to one of the wheelchair or the seat back and a pin receiver configured to be mounted in relation to the other one of the wheelchair or the seat back, the mounting pin being structured to be received by the pin receiver to mount the seat back in relation to the wheelchair. 
     
     
         4 . The wheelchair seat back assembly of  claim 3  wherein the pin receiver is supported in relation to a mounting bracket by fasteners that pass through by one or more slots in the mounting bracket, the fasteners mounting the pin receiver in relation to the mounting bracket, the slots being oversized to permit the pin receiver to be angularly adjustable in relation to the mounting bracket. 
     
     
         5 . The wheelchair seat back assembly of  claim 3  wherein the mounting pin and the pin receiver are conically shaped. 
     
     
         6 . The wheelchair seat back assembly of  claim 1  wherein the mounting hardware comprises a tube clamp configured to be mounted to wheelchair seat posts of various size and shape. 
     
     
         7 . The wheelchair seat back assembly of  claim 6  wherein the tube clamp has inner and outer parts with flat and V-shaped geometries and a swivel pin engageable with one or more fasteners, the swivel post along with the flat and V-shaped geometries being configured to permit the tube clamp to be adapted to a variety of post sizes and shapes. 
     
     
         8 . The wheelchair seat back assembly of  claim 1  wherein the mounting hardware is configured to adjust the seat back to various width ranges of wheelchairs and also adjust in height, angle and depth. 
     
     
         9 . The wheelchair seat back assembly of  claim 1  wherein the mounting hardware is self-locking in an open position upon pushing a locking lever in a first direction and when detaching the seat back, the locking lever is reset in a closed position, so that when the seat back is reattached to the wheelchair, the seat back is securely self-locked into place.
