Patent ID: 8662083

Claim:
A blank for a head restraint comprising: a frame having an open end; and a deformable sheet extending across the frame, the sheet defining a main aperture at a central portion within the frame, and a pair of auxiliary apertures on either side of the main aperture adjacent the open end of the frame, the main and auxiliary apertures being configured such that when the sheet is deformed upon placement on a patient's head within the frame: 1) a portion of the sheet remote from the open end of the frame deforms to enclose the top of the patient's head, and 2) a portion of the sheet adjacent the open end of the frame deforms to define a chin strap enclosing the patient's chin, the main aperture being configured so as to leave the patient's face substantially free of the sheet, and the main and auxiliary apertures being configured so as to define a retaining strut between an attachment point adjacent the frame to the portion of the sheet deformed to become the chin strap enclosing the patient's chin, the retaining strut being formed by portions of the sheet between said main aperture and said auxiliary apertures.
