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 with an additive are positioned in each outer pocket. At least one cushion pad, at least one buckling member with an additive or any combination thereof may be individually pocketed inside an outer pocket.
Claims20
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 each of said strings 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 at least some of the buckling members contain phase change materials and have an outer wall and internal ribs extending inwardly from the outer wall to a center.
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 and further wherein the buckling member contains phase change materials.
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 each of the strings, 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 and further wherein each of the buckling members contains phase change materials.
