ABSTRACT:
Each of the padded arm rests of a wheelchair are supported by downwardly extending telescoping tubes received in correspondingly positioned vertical tubes secured to the frame of the wheelchair. A locking device biased to a normally locked position causes a projection to extend into registered openings in the telescoping tubes so that the arm rest can be positioned at a selected height. The locking arrangement defines a large exposed engaging surface which can easily be urged in a proper direction to release the lock by a portion of the body of a patient seated in the wheelchair.
