Abstract
A dental instrument delivery system is provided which includes an articulated retaining arm adjustable in a plurality of directions. The arm is connected to a cable mechanism in the back rest of a dental chair which allows the instruments carried by the arm to remain in a desired position when the back rest is tilted. Also included is a safety release system which prevents damage to the arm and instruments it carries should they accidentally engage a solid object when the chair and/or back rest is raised or lowered. After disengagement of the solid object, the arm automatically returns to its original position.
