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. Outer pockets are formed along each string by transverse seams joining the first and second plies. One pocketed spring, at least cushion pad and at least one buckling member are positioned in each outer pocket. At least one cushion pad, at least one buckling member or any combination thereof may be individually pocketed inside an outer pocket.

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 inner pocketed springs, a plurality of cushion pads and a plurality of buckling members, first and second opposed plies of fabric being on opposite sides of the inner pocketed springs, cushion pads and buckling members, 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 inner pocketed spring and at least one cushion pad and at least one buckling member being in each of said outer pockets, wherein each of the buckling members has an outer wall, internal ribs extending inwardly from the outer wall to a center, an open top and an open bottom defining passages between the internal ribs.

2. The product of claim 1 , wherein each of the outer pockets includes a combination pad above the inner pocketed coil spring, the combination pad comprising one of the cushion pads and one of the buckling members which in combination are encased in a fabric cover.

3. The product of claim 1 , wherein an upper end of each of said transverse seams is below an upper surface of the string to partially separate adjacent outer pockets.

4. The product of claim 1 , wherein one of the cushion pads and one of the buckling members are pocketed together inside one of the outer pockets.

5. The product of claim 1 , wherein two cushion pads and two buckling members are in each of the outer pockets.

6. The product of claim 1 , wherein at least one cushion pad and at least one buckling member are above one of the inner pocketed springs inside each of the outer pockets.

7. 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 an inner pocketed spring and a combination pad, the combination pad comprising a cushion pad and a buckling member encased together in a fabric cover, 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, wherein the buckling member has an outer wall, internal ribs extending inwardly from the outer wall to a center, an open top and an open bottom defining passages between the internal ribs.

8. The pocketed spring assembly of claim 7 , wherein two cushion pads and two buckling members are in each of the outer pockets.

9. The pocketed spring assembly of claim 8 , wherein said inner pocketed spring is between the cushion pads and between the buckling members in each of the outer pockets.

10. The pocketed spring assembly of claim 7 , 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.

11. The pocketed spring assembly of claim 10 , wherein the inner pocketed springs are below the upper end of adjacent transverse seams.

12. The pocketed spring assembly of claim 7 , wherein each of said cushion pads is made at least partially of foam.

13. The pocketed spring assembly of claim 7 , wherein the buckling member has four internal ribs.

14. 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 a combination pad comprising at least one cushion pad and at least one buckling member, 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 the buckling members has an outer wall, internal ribs extending inwardly from the outer wall to a center, an open top and an open bottom defining passages between the internal ribs.

15. The pocketed spring assembly of claim 14 , wherein each of the buckling members has four internal ribs.

16. The pocketed spring assembly of claim 14 , wherein said buckling members are made of plastic.

17. The pocketed spring assembly of claim 14 , wherein each of said buckling members is individually pocketed with at least one of the cushion pads.

18. The pocketed spring assembly of claim 14 , wherein the cushion pads are made at least partially of foam.

19. The pocketed spring assembly of claim 14 , wherein at least one of the buckling members has a hollow interior.
