Abstract
Abstract A pocket spring upholstery cushioning comprised of helical springs respectively encapsulated in a pod of flexible foam plastic and all mutually interconnected in co-planar, side by side assembly by an integral web of the same material. Said web has a thickness of less than the axial heights of the pods and connects them by their ends on one side only of the cushioning permitting independent relative movement of the spring ends on the other side of the cushioning.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
169 words
Spring cushioning including: a plurality of helical upholstery springs assembled in axially erect, side-by-side relation with one another and forming a two-sided assembly, the respective spring ends on each side of the assembly being co-planar with each other; a pod of resilient material investing each said spring from one end to the other thereof and forming therewith an integrated resilient element which is hollow over a major portion of its height, at least, and a resilient web interconnecting and merging with the said pods at one side only of said assembly and retaining them in said assembly, the other ends of said pods being detached from each other and free to move relative thereto; the said resilient elements being shaped to permit such movement and the resilience of the investment being insufficient to prevent compression of said free pod ends independently of one another under normal load but being sufficient nevertheless to resist deflection of said pod ends out of the erect side-by-side relation aforesaid under said normal load.
Claim 2
Dependent Claim
169 words
Spring cushioning including: a plurality of helical upholstery springs assembled in axially erect, side-by-side relation with one another and forming a two-sided assembly, the respective spring ends on each side of the assembly being co-planar with each other; a pod of resilient material investing each said spring from one end to the other thereof and forming therewith an integrated resilient element which is hollow over a major portion of its height, at least, and a resilient web interconnecting and merging with the said pods at one side only of said assembly and retaining them in said assembly, the other ends of said pods being detached from each other and free to move relative thereto; the said resilient elements being shaped to permit such movement and the resilience of the investment being insufficient to prevent compression of said free pod ends independently of one another under normal load but being sufficient nevertheless to resist deflection of said pod ends out of the erect side-by-side relation aforesaid under said normal load.
Claim 3
Dependent Claim
36 words
Spring cushioning as set forth in claim 1 wherein: said resilient elements are tapered providing widened zones below their tops and valleys therebetween; said resilient elements being interconnected with said resilient web by their widest zones.
Claim 4
Dependent Claim
25 words
Spring cushioning as set forth in claim 2 wherein: said web is integral with said pods; said web and pods being formed of an elastomer.
Claim 5
Dependent Claim
17 words
Spring cushioning as set forth in claim 3 including: a pad integral with said pods and web.
Claim 6
Dependent Claim
17 words
Spring cushioning as set forth in claim 4; said pods and web being formed of an elastomer.
Claim 7
Dependent Claim
17 words
Spring cushioning as set forth in claim 4; said pods and web being formed of polyurethane foam.
