Abstract

A pocketed spring assembly comprises a plurality of parallel strings of springs, each string joined to at least one adjacent string, each string comprising one piece of fabric folded into first and second opposed plies of fabric. Outer pockets are formed along each string by transverse seams joining the first and second plies. One pocketed spring and at least cushion pad is positioned in each outer pocket. The cushion pad may be individually pocketed. An upper end of each transverse seam may be below an upper surface of the string to partially separate adjacent outer pockets within a string.

First claim

What is claimed is:

1. A bedding or seating product comprising:
a pocketed spring assembly comprising a plurality of parallel strings of springs, each of said strings being joined to at least one adjacent string, each of said strings comprising a piece of fabric surrounding a plurality of pocketed springs and a plurality of cushion pads, first and second opposed plies of fabric being on opposite sides of the pocketed springs and cushion pads, a plurality of outer pockets formed along said string by a longitudinal seam and transverse seams joining said first and second plies, at least one pocketed spring and at least one cushion pad being in each of said outer pockets;
cushioning materials; and
a covering encasing said pocketed spring assembly and cushioning materials.

2. A bedding or seating product comprising:
a pocketed spring assembly comprising a plurality of parallel strings of springs, each of said strings being joined to at least one adjacent string, each of said strings comprising a piece of fabric surrounding a plurality of pocketed springs and a plurality of cushion pads, first and second opposed plies of fabric being on opposite sides of the pocketed springs and cushion pads, a plurality of outer pockets formed along said string by a longitudinal seam and transverse seams joining said first and second plies, at least one pocketed spring and at least one cushion pad being in each of said outer pockets.

3. The product of claim 2 , wherein each of the cushion pads is individually pocketed.

4. The product of claim 2 , wherein an upper end of each of said transverse seams is below an upper surface of the string to partially separate adjacent outer pockets.

5. The product of claim 2 , wherein said longitudinal seam is a side seam.

6. The product of claim 2 , wherein two cushion pads are in each of said outer pockets.

7. The product of claim 2 , wherein each of the springs has a central portion of a uniform diameter.

8. A pocketed spring assembly for a bedding or seating product, said pocketed spring assembly comprising:
a plurality of parallel strings of springs, each of the strings being joined to at least one adjacent string, each of the strings comprising a plurality of interconnected outer pockets made from one piece of fabric, each of the outer pockets containing at least one inner pocketed spring and at least one cushion pad, the piece of fabric being joined to itself along a longitudinal seam and having first and second opposed plies of fabric on opposite sides of the springs, the first and second plies being joined by transverse seams between adjacent inner pocketed springs.

9. The pocketed spring assembly of claim 8 , wherein two cushion pads are in each of said outer pockets.

10. The pocketed spring assembly of claim 9 , wherein said at least one inner pocketed spring is between the cushion pads.

11. The pocketed spring assembly of claim 8 , wherein each of said transverse seams forming adjacent outer pockets of said string has one end located below an upper surface of said string to partially separate adjacent outer pockets.

12. The pocketed spring assembly of claim 11 , wherein the inner pocketed springs are below the upper end of adjacent transverse seams.

13. The pocketed spring assembly of claim 8 , wherein each of said cushion pads is made at least partially of foam.

14. The pocketed spring assembly of claim 8 , wherein each of the cushion pads is individually pocketed.

15. A pocketed spring assembly for a bedding or seating product, said pocketed spring assembly comprising:
a plurality of parallel strings of springs, each of the strings being joined to an adjacent string, each of the strings comprising a plurality of interconnected outer pockets made from one piece of fabric, each of the outer pockets containing one inner pocketed spring and at least one cushion pad, the piece of fabric being joined to itself along a longitudinal seam and having first and second opposed plies of fabric on opposite sides of the inner pocketed springs, the fabric of said first and second plies being joined by transverse seams, each of the transverse seams being shorter than the string,
wherein each of said transverse seams forming adjacent pockets of said string has an upper end located below an upper surface of said string to partially separate said adjacent outer pockets and enable some of the cushion pads to compress without substantially compressing other cushion pads within other outer pockets.

16. The pocketed spring assembly of claim 15 , wherein the upper end turn and multiple convolutions of each of said springs are above the upper end of adjacent transverse seams.

17. The pocketed spring assembly of claim 15 , wherein said strings of springs extend longitudinally.

18. The pocketed spring assembly of claim 15 , wherein said strings of springs extend transversely.

19. The pocketed spring assembly of claim 15 , wherein the longitudinal seam of each of said strings is located along a side of the string.

20. The pocketed spring assembly of claim 15 , wherein one of the end portions of the spring has more convolutions than the other end portion of the spring.
