Abstract

Abstract The invention comprises a therapeutic pillow (10) for supporting the head and neck of a person lying in a supine position. The pillow (10) comprises a pair of pillow members (11) and (12) combined to form a single pillow. Pillow member (11) has upper opposite sides (16) and (21) joined to the upper portions of opposed edges (17) and (19), one of which is higher or thicker than the other, a planar surface (18) joining the lower portions of the edges (17) and (19), and a normally non-exposed irregular surface (23-28) extended between the sides (16) and (21). The second pillow (12) has one side (32-37) that mates with the irregular surface of the first pillow member (11) and an opposite side (31) which is relatively smooth. The density of the two pillow members varies, member (11) being more dense than member (12).

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 233 words
A pillow for supporting the head and neck of a person lying in a supine or side position, comprising: a first pillow member having upper opposite sides, opposed edges, a planar surface, and an irregular surface extended between said sides and having an upper wall and a lower wall generally parallel to said planar surface, the said sides extended partially over said planar surface; and a second pillow member having one irregular surface mated with said first member irregular surface such that said second member is nested between said opposite sides, and having a second surface forming a relatively smooth surface with the opposite sides of said first member, wherein said pillow members have differing consistencies to present different resistances, and wherein said first pillow member opposed edged have different thicknesses, said pillow being reversible whereby to provide a quartet of different support positions for the head and neck of the person using same; and further wherein said pillow members form at least a pair of different resistances between the opposite sides, a first resistance comprised of a thin cross-section of general constant thickness of said second pillow member and a thick cross-section of general constant thickness of said first pillow member, and a second resistance comprised of a thick cross-section of general constant thickness of said second pillow member and a thin cross-section of general constant thickness of said first pillow member.
Claim 2
Dependent Claim 233 words
A pillow for supporting the head and neck of a person lying in a supine or side position, comprising: a first pillow member having upper opposite sides, opposed edges, a planar surface, and an irregular surface extended between said sides and having an upper wall and a lower wall generally parallel to said planar surface, the said sides extended partially over said planar surface; and a second pillow member having one irregular surface mated with said first member irregular surface such that said second member is nested between said opposite sides, and having a second surface forming a relatively smooth surface with the opposite sides of said first member, wherein said pillow members have differing consistencies to present different resistances, and wherein said first pillow member opposed edged have different thicknesses, said pillow being reversible whereby to provide a quartet of different support positions for the head and neck of the person using same; and further wherein said pillow members form at least a pair of different resistances between the opposite sides, a first resistance comprised of a thin cross-section of general constant thickness of said second pillow member and a thick cross-section of general constant thickness of said first pillow member, and a second resistance comprised of a thick cross-section of general constant thickness of said second pillow member and a thin cross-section of general constant thickness of said first pillow member.
