ABSTRACT:
Rear left and right vertically disposed wheelchair frame tubes are arranged to telescopically receive left and right back rest tubes supporting the main back rest portion of the wheelchair. The lower ends of the back rest tubes include downwardly directed rods spaced to the sides of the tubes and designed to be received in appropriate binding structures secured to the wheelchair frame to automatically lock the back rest tubes to the frame to position the back rest itself properly for a patient. The binding elements may easily be manually released to permit telescopic removal of the back rest tubes from the wheelchair frame itself.
