ABSTRACT:
Front and rear downwardly extending arm rest support tubes are received in correspondingly positioned front and rear vertical receiving tubes on the side of a wheelchair. An integral S-shaped rod has an upper horizontal extending portion arranged to project into registered openings in the front telescoping tubes so that an arm rest on the arm rest support tubes can be positioned at a selected height and locked in such adjusted position. The S-shaped rod also functions as a handle to be engaged by the web of a patient's hand between the thumb and forefinger. Urging of the S shaped rod forwardly unlocks the tubes permitting vertical adjustment. A spring biases the S shaped rod rearwardly to effect automatic locking of the tubes in the adjusted position when the handle portion of the rod is released.
