Abstract:
A blank for a head restraint is disclosed. The blank includes a frame and a sheet extending across the frame wherein a main aperture and a pair of auxiliary apertures are provided in the sheet. The arrangement of the apertures is such that when the sheet is deformed upon placement on a patient's head, the main aperture is such to leave a patient's face substantially free of the sheet and the auxiliary apertures are such to cause a retaining strut to be formed by portions of the sheet between the main aperture and the auxiliary apertures.
