Abstract

A method for forming a cushioning element comprises molding a first cushioning element on a first side of a fabric and molding a second cushioning element on a second side of the fabric. The first cushioning element and second cushioning element may be superimposed. The fabric may include a first layer and a second layer that are superimposed, with the first cushioning element secured to and protruding from the first layer and the second cushioning element secured to and protruding from the second layer. Each of the first cushioning element and second cushioning element may include a plurality of interconnected walls formed from an elastomeric gel material. The walls of the first cushioning element and second cushioning element may be aligned or offset.

First claim

What is claimed:

1 . A method for forming a cushioning element in a single molding step, the single molding step comprising:
placing overlapping layers of fabric between two parts of a mold with at least one mold cavity of the mold on each side of the overlapping layers of fabric, the overlapping layers of fabric comprising a first fabric coupled with a second fabric; with the two parts of the mold, concurrently molding a first cushioning element on the first fabric and molding a second cushioning element on the second fabric; and separating portions of the first fabric and the second fabric to thereby form a primary receptacle.

2 . The method of claim 1 , wherein placing the overlapping layers of fabric between the two parts of the mold comprises placing a scrim comprising cotton between the two parts of the mold.

3 . The method of claim 1 , wherein material of the first cushioning element extends through the first fabric to secure the first cushioning element to the first fabric.

4 . The method of claim 1 , wherein molding the first cushioning element comprises molding the first cushioning element from a compressible, resilient elastomeric material.

5 . The method of claim 4 , wherein molding the first cushioning element comprises molding a plurality of interconnected walls defining an array of cells.

6 . The method of claim 4 , wherein molding the second cushioning element comprises molding the second cushioning element from a compressible, resilient elastomeric material.

7 . The method of claim 6 , wherein:
molding the first cushioning element comprises molding a first plurality of interconnected walls defining a first array of cells; and molding the second cushioning element comprises molding a second plurality of interconnected walls defining a second array of cells.

8 . The method of claim 7 , wherein molding the first plurality of interconnected walls and molding the second plurality of interconnected walls comprising molding the first plurality of interconnected walls and the second plurality of interconnected walls to be completely superimposed with each other.

9 . A method for forming a cushioning element in a single molding step, the single molding step comprising:
placing overlapping layers of fabric between two parts of a mold, the overlapping layers of fabric comprising a first fabric coupled with a second fabric; with the two parts of the mold, concurrently molding a first cushioning element on the first fabric of the overlapping layers of fabric and molding a second cushioning element on the second fabric of the overlapping layers of fabric; and separating portions of the first fabric and the second fabric to form a primary receptacle.

10 . The method of claim 9 , wherein molding the first cushioning element comprises molding an elastomeric material to define a first plurality of interconnected walls onto the first fabric, the first plurality of interconnected walls defining a first array of cells of the first cushioning element.

11 . The method of claim 10 , wherein molding the elastomeric material defines walls at a periphery of the first plurality of interconnected walls with heights of about one-eighth inch.

12 . The method of claim 10 , wherein molding the elastomeric material defines walls at a periphery of the first plurality of interconnected walls with heights of about one sixteenth inch.

13 . The method of claim 10 , wherein a periphery of the first plurality of interconnected walls is shorter than a center of the first plurality of interconnected walls.

14 . The method of claim 10 , wherein molding the elastomeric material comprises molding the elastomeric material onto a scrim.

15 . The method of claim 9 , wherein
subsequent to separating the portions of the first fabric and the second fabric, the first cushioning element remains adhered to the first fabric and the second cushioning element remains adhered to the second fabric.

16 . A method for forming a cushion in a single molding step, the single molding step comprising:
concurrently molding a first cushioning element onto a first fabric of overlapping layers of fabric and a second cushioning element onto a second fabric of the overlapping layers of fabric; and separating portions of the first fabric and the second fabric to form a primary receptacle, wherein the first cushioning element is formed of an elastomeric material defining a plurality of interconnected walls on the first fabric, the plurality of interconnected walls being compressible and resilient, defining an array of cells, and having heights of about a half an inch or less, the first fabric remaining adhered to bases of the plurality of interconnected walls.

17 . The method of claim 16 , wherein the elastomeric material defines walls at a periphery of the plurality of interconnected walls with heights of about one-eighth inch.

18 . The method of claim 16 , wherein the elastomeric material defines walls at a periphery of the plurality of interconnected walls with heights of about one sixteenth inch.

19 . The method of claim 16 , wherein a periphery of the plurality of interconnected walls is shorter than a center of the plurality of interconnected walls.

20 . The method of claim 16 , wherein molding the first cushioning element comprises molding the elastomeric material onto a scrim.

21 . The method of claim 16 , further comprising:
placing the overlapping layers of fabric between two sides of a mold, wherein molding the first cushioning element and the second cushioning element comprises molding elastomeric material to define pluralities of interconnected walls onto the first fabric and the second fabric of the overlapping layers of fabric, each plurality of interconnected walls defining an array of cells.

22 . The method of claim 21 , wherein
subsequent to separating the portions of the first fabric and the second fabric, each plurality of interconnected walls remains adhered to its corresponding layer of fabric.
