Abstract
Abstract A multi-dimensional pillow comprising a core having a cross sectional thickness gradient along one dimension and at least one geometric piece attached to the core parallel to the direction of the thickness gradient. When the user is in the back-lying position, the geometric piece maintains either the normal lordotic curve of the neck or flexion of the neck and the thickness gradient biases the head in the downslope direction causing a controlled rotation of the head resulting in a traction effect on the upslope side of the neck. The traction effect is due to the coupled easy natural biomechanical motions of side bending and side rotation of the neck to the same side.

Total Claims: 4
Claim 1
Independent Claim
239 words
A pillow comprising a core comprising a first and second widthwise edge, a thick lengthwise edge and a thin lengthwise edge, said core also comprising a low raised contoured border extending the length of said thin lengthwise edge and a high raised contoured border extending the length of said thick lengthwise edge; said low raised contoured border and said high raised contoured border each having a base; said core having a central portion defined by said high raised contoured border base and said low raised contoured border base; said central portion having a thickness gradient from said high raised contoured border base to said low raised contoured border base; a first piece having a triangular cross section attached to said core at said first widthwise edge between said high raised contoured border base and said low raised contoured border base; a second piece having a triangular cross section attached to ssid core at said second widthwise edge between said high raised contoured border base and said low raised contoured border base; a sculptured overwrap encasing said core, said first triangular piece and said second triangular piece, said sculptured overwrap comprising a deep pile convolution region and a shallow pile convolution region, said shallow pile convolution region encasing said high raised contoured border, said low raised contoured border, said central portion, said first triangular piece and said second triangular piece, said deep pile convolution encasing the remainder of said core.
Claim 2
Dependent Claim

A pillow comprising a core comprising a first and second widthwise edge, a thick lengthwise edge and a thin lengthwise edge, said core also comprising a low raised contoured border extending the length of said thin lengthwise edge and a high raised contoured border extending the length of said thick lengthwise edge; said low raised contoured border and said high raised contoured border each having a base; said core having a central portion defined by said high raised contoured border base and said low raised contoured border base; said central portion having a thickness gradient from said high raised contoured border base to said low raised contoured border base; a first piece having a triangular cross section attached to said core at said first widthwise edge between said high raised contoured border base and said low raised contoured border base; a second piece having a triangular cross section attached to ssid core at said second widthwise edge between said high raised contoured border base and said low raised contoured border base; a sculptured overwrap encasing said core, said first triangular piece and said second triangular piece, said sculptured overwrap comprising a deep pile convolution region and a shallow pile convolution region, said shallow pile convolution region encasing said high raised contoured border, said low raised contoured border, said central portion, said first triangular piece and said second triangular piece, said deep pile convolution encasing the remainder of said core.
Claim 3
Dependent Claim
35 words
