Abstract
Official abstract text for this publication.
A pocketed spring, such as that used in a mattress, comprises: a compression spring having an upper end convolution and a lower end convolution opposite the upper end convolution, and a plurality of helical intermediate convolutions between the upper end convolution and the lower end convolution; a flexible enclosure including a top wall positioned adjacent to the upper end convolution of the compression spring, a bottom wall positioned adjacent to the lower end convolution of the compression spring, and a side wall that extends from the top wall to the bottom wall; and a tension member connected to the flexible enclosure. The tension member acts in opposition to the compression spring until the pocketed spring is compressed to a point at which the tension member no longer applies any force. Thus, the pocketed spring exhibits a non-linear response when compressed.
First claim
Opening claim text (preview).
What is claimed is: 1. A mattress comprising: a plurality of pocketed springs arranged in a matrix and defining a first support surface and a second support surface opposite the first support surface, with each of the plurality of pocketed springs including (a) a compression spring having an upper end convolution and a lower end convolution opposite the upper end convolution, and a plurality of helical intermediate convolutions between the upper end convolution and the lower end convolution, (b) a flexible enclosure including a fabric top wall positioned adjacent to the upper end convolution of the compression spring, a fabric bottom wall positioned adjacent to the lower end convolution of the compression spring, and a side wall that extends continuously from the fabric top wall to the fabric bottom wall, and (c) a tension member connected to the flexible enclosure, said tension member acting opposite to the compression spring and being connected to the fabric top wall and the fabric bottom wall; an upper body supporting layer positioned adjacent to the first support surface; a lower foundation layer positioned adjacent to the second support surface; and a side panel extending between the upper body supporting layer and the lower foundation layer. 2. The mattress of claim 1 , wherein the tension member of each of said plurality of pocketed springs is made of an elastomer. 3. The mattress of claim 2 , wherein the elastomer is laminated to substantially all of the side wall of the flexible enclosure of each of said plurality of pocketed springs. 4. The mattress of claim 2 , wherein the elastomer is comprised of latex or neoprene.
