Patent

CA 2299483

The invention provides a head support apparatus. The apparatus may for example be used for ophthalmic examination. In some embodiments, the apparatus may allow six degrees of freedom of motion during initial positioning of a patient's head, and may then be locked to hold the patient's head in place precisely. The head support mechanism may include three shafts connecting an upper frame to a structure. Each shaft may be provided with a ball-and- socket joint at one end and a lockable bearing assembly on the other end. The lockable bearing assembly may provide a combination of sliding and pivotal movement. A biasing assembly may be provided to support each shaft, and to return each shaft to a self centered and fully lifted rest position. A head clamping apparatus is also disclosed comprising pivoting clamping arms and an adjustable chin rest.
