Claim 1

In a surgical headrest of the type including a bracket for attachment of the headrest to an operating room table, a first arcuate base segment having a first end affixed to said bracket and a second free end, an elongate pin affixed to said bracket, a second arcuate base segment having a curvature which is the mirror image of the curvature of said first arcuate segment and having a first end adapted to be movably secured to said elongate pin to adjust the size of the headrest and a second free end, each of said base segments having an inwardly facing surface and an opposed outwardly facing surface and a top edge and a bottom edge, each inwardly facing surface being concave and each opposed surface being irregular, said concave surface being set at an angle of between 30 and 60 degrees as measured between a plane passing through the top and bottom edges at the free ends of said base segments and a plane perpendicular to the axis of said elongate pin, a headrest pad having an inwardly facing side and an opposed side, the improvement comprising a cavity in said pad which extends along the length of said pad, said cavity having an open end and a closed end and a cross sectional configuration which is congruent with the cross sectional configuration of the base segment to which said pad is affixed, the inwardly facing surface of said pad being at an angle substantially equal to the angle of the concave surface of the base segment to which it is affixed, a longitudinally extending slot on said opposed side of said pad extending along a portion of the length of said pad, a first transverse slot at the open end of said cavity and a second transverse slot spaced from said first transverse slot along the length of said longitudinally extending slot, said longitudinally extending slot and said transverse slots joining with said cavity to receive the arcuate segments and thereby affix said pads to said arcuate segments.
