Abstract

Abstract This pillow is a flat substantially rectangular block of material that is more resilient on its upper top layer and is less resilient on its lowermost layer. It is substantially rectangular overall, but has a cutout in at least one of the longer rectangular sides, although this cutout may be repeated in the opposite rectangular side. The cutout is substantially circular, more or less, and is not greater than a semi-circle, although it may be somewhat less than a semi-circle, the cutout serving to receive the sleeper''s shoulder with the attached arm extendable beyond the pillow and not subject to any pressure from the pillow, being entirely free thereof, and, of course, free of any pressure from the sleeper''s head. The thickness of the pillow is such that the sleeper''s head is supported in a horizontal position, with the neck and windpipe free of any bends. As a result, breathing is freer than with a conventional pillow, where the arm is often extended under the pillow attempting to hold the head horizontal, in which it often fails, but such does succeed in restricting the blood flow in the arm, leading to a condition strongly resembling bursitis in pain and restriction of arm movement, a painful condition not easily remedied.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 170 words
A therapeutic pillow (10) for comfortably supporting the head and neck of the user in bed in a substantially horizontal position while lying on one''s side leaving the lower arm free of constriction comprising a substantially flat, one piece, solid rectangular body of resilient material, said material having a cutout (20) to receive one shoulder of the user while leaving the attached arm thereof free from constriction by the weight of the head of the user, said cutout (20) extending vertically through one long edge (24) of the pillow (10) midway of and spaced from its short end edges, said cutout (20) having a contour substantially approaching but not greater than a semi-circle, said one piece solid body being comprised of two horizontal uniform layers (16 and 18) integrally united, the upper layer (16) being of substantially greater height and resiliency and lesser uniform density than the lower layer (18), the height of the upper more resilient layer (16) being approximately three times that of the lower, firmer layer (18).
Claim 2
Dependent Claim 170 words
A therapeutic pillow (10) for comfortably supporting the head and neck of the user in bed in a substantially horizontal position while lying on one''s side leaving the lower arm free of constriction comprising a substantially flat, one piece, solid rectangular body of resilient material, said material having a cutout (20) to receive one shoulder of the user while leaving the attached arm thereof free from constriction by the weight of the head of the user, said cutout (20) extending vertically through one long edge (24) of the pillow (10) midway of and spaced from its short end edges, said cutout (20) having a contour substantially approaching but not greater than a semi-circle, said one piece solid body being comprised of two horizontal uniform layers (16 and 18) integrally united, the upper layer (16) being of substantially greater height and resiliency and lesser uniform density than the lower layer (18), the height of the upper more resilient layer (16) being approximately three times that of the lower, firmer layer (18).
Claim 3
Dependent Claim 25 words
The pillow of claim 1, said material being more resilient polyurethane in the upper layer (16), and less resilient polyurethane in the lower layer (18).
