Patent attributes
A headrest assembly includes a frame, a first head support configured and dimensioned to support a forehead of a patient, and a second head support configured and dimensioned to support a chin of the patient. An adjustment mechanism is mounted to the frame and is operable to adjust the position of at least one of the first and second head supports relative to the frame. The first and second head supports having at least two degrees of freedom relative to a longitudinal plane and at least one degree of freedom relative to an axial plane that is orthogonal to the longitudinal plane. The longitudinal plane extends parallel to an X axis and also extends parallel to a Y axis that is orthogonal to the X axis. The axial plane extends parallel to one of the X axis and the Y axis. The axial plane also extends parallel to a Z-axis that is orthogonal to both the X axis and the Y axis.
