Abstract
Official abstract text for this publication.
A unitary deflection member. The unitary deflection member can have a backside defining an X-Y plane and a thickness in a Z-direction. The unitary deflection member can also have a reinforcing member and a plurality of protuberances positioned on the reinforcing member. Each protuberance can have a three-dimensional shape such that any cross-sectional area of the protuberance parallel to the X-Y plane can have an equal or greater area than any cross-sectional area of the protuberance being a greater distance from the X-Y plane in the Z-direction.
First claim
Opening claim text (preview).
What is claimed is: 1. A unitary deflection member, the unitary deflection member having a backside defining an X-Y plane and a thickness in a Z-direction, and further comprising a reinforcing member and a plurality of protuberances positioned on the reinforcing member, wherein each protuberance has a three-dimensional shape such that any cross-sectional area of the protuberance parallel to the X-Y plane has an equal or lesser area than any cross-sectional area of the protuberance being a greater distance from the X-Y plane in the Z-direction. 2. The deflection member of claim 1 , wherein the at least two of said protuberances are adjacent one another and separated by a void defining a deflection conduit. 3. The deflection member of claim 1 , wherein said plurality of regularly spaced protuberances are linear segments spaced apart in either the MD or CD. 4. The deflection member of claim 1 , wherein said plurality of regularly spaced protuberances are generally parallel linear segments oriented predominantly in the MD or CD. 5. The deflection member of claim 1 , wherein said plurality of regularly spaced protuberances are linear segments, the linear segments having a cross-sectional shape, the cross-sectional shape being selected from smooth rounded, pointed, ridged, and stepped, multilevel. 6. The deflection member of claim 1 , wherein the plurality of regularly spaced protuberances are disposed in a regular, spaced apart configuration of discrete units in an X-Y plane and distributed in both the MD and CD in a regular, spaced pattern. 7. The deflection member of claim 1 , wherein the plurality of regularly spaced protuberances are discrete units disposed in a regular, spaced apart configuration in both the MD and CD, each discrete unit having a cross-sectional shape, the cross-sectional shape being selected from smooth rounded, pointed, ridged, and stepped, multilevel. 8. The deflection member of claim 1 , wherein at least two of the plurality of regularly spaced protuberances are substantially identical in size and shape.
