Claim 4

An upholstered body in combination according to claim 2, in which said intermediate layer means have marginal areas embedded in said stiffening means and together with said stiffening means from lateral surfaces on the inside of said slot means.

Claim 5

An upholstered body, especially mattress, which includes: a spring core comprising a plurality of rows of helical springs arranged in an axis-parallel manner with regard to each other, at least one cover plate means of elastic foamed material arranged in spaced axial relationship to and at least at one end of said springs while covering up the respective adjacent ends of all of said springs and projecting laterally and longitudinally beyond said spring core, marginal body means arranged on at least two oppositely located sides of said upholstered body, intermediate layer means interposed between said cover plate means and said springs, bend-elastic barshaped stiffening means arranged on and connected to said marginal body means and having said intermediate layer means connected thereto, corner sections located near said marginal body means, said marginal body means within the region of said corner sections respectively having extensions merging with the inner lateral surfaces of said corner sections forming portions of said marginal body means, and forming lateral surfaces opposite the respective adjacent cover plate means for engagement with end windings of those of said springs which are located at said corner sections.

Claim 6

An upholstered body, especially mattress, which includes: a spring core comprising a plurality of rows of helical springs arranged in an axis-parallel manner with regard to each other, at least one cover plate means of elastic foamed material arranged in spaced axial relationship to and at least at one end of said springs while covering up the respective adjacent ends of all of said springs and projecting laterally and longitudinally beyond said spring core, marginal body means arranged on at least two oppositely located sides of said upholstered body, intermediate layer means interposed between said cover plate means and said springs, bend-elastic barshaped stiffening means arranged on and connected to said marginal body means and having said intermediate layer means connected thereto, corner sections located near said marginal body means, said marginal body means within the region of said corner sections respectively having extensions merging with the inner lateral surfaces of said corner sections forming portions of said marginal body means, and forming lateral surfaces opposite the respective adjacent cover plate means for engagement with end windings of those of said springs which are located at said corner sections.

Claim 7

An upholstered body according to claim 4, which includes a fabric cover enveloping said upholstered body, and in which the inner lateral surfaces of said marginal body means exclusively engage the mantle surfaces of those of said springs which are located at the marginal areas of said spring core, said last mentioned spring preloading said fabric cover.

Claim 8

An upholstered body according to claim 4, in which said stiffening means respectively form one single entity with the respective adjacent marginal body means.

Claim 9

An upholstered body according to claim 4, in which said stiffening means are embedded in the inner-side of the adjacent cover plate means and connected thereto.

Claim 10

An upholstered body, especially mattress, which includes: a spring core comprising a plurality of rows of helical springs arranged in an axis-parallel manner with regard to each other, at least one cover plate means of elastic foamed material arranged in spaced axial relationship to and at least at one end of said springs while covering up the respective adjacent ends of all of said springs and projecting laterally and longitudinally beyond said spring core, marginal body means arranged on at least two oppositely located sides of said upholstered body, intermediate layer means interposed between said cover plate means and said springs, bend-elastic bar-shaped stiffening means arranged on and connected to said marginal body means and having said intermediate layer means connected thereto, said stiffening means forming lateral and bottom surfaces of slot means for engagement by adjacent end windings of said helical springs, said intermediate layer means having marginal areas embedded in said stiffening means and together with said stiffening means forming lateral surfaces on the inside of said slot means, said marginal areas of said intermediate layer means forming a compacted thinner section than the remaining portion of said intermediate layer means and being permeated with the synthetic foam material of said stiffening means.

Claim 11

An upholstered body, especially mattress, which includes: a spring core comprising a plurality of rows of helical springs arranged in an axis-parallel manner with regard to each other, at least one cover plate means of elastic foamed material arranged in spaced axial relationship to and at least at one end of said springs while covering up the respective adjacent ends of all of said springs and projecting laterally and longitudinally beyond said spring core, marginal body means arranged on at least two oppositely located sides of said upholstered body, intermediate layer means interposed between said cover plate means and said springs, bend-elastic bar-shaped stiffening means arranged on and connected to said marginal body means and having said intermediate layer means connected thereto, said stiffening means forming lateral and bottom surfaces of slot means for engagement by adjacent end windings of said helical springs, said intermediate layer means having marginal areas embedded in said stiffening means and together with said stiffening means forming lateral surfaces on the inside of said slot means, said marginal areas of said intermediate layer means forming a compacted thinner section than the remaining portion of said intermediate layer means and being permeated with the synthetic foam material of said stiffening means.

Claim 12

An upholstered body according to claim 8, in which said stiffening means in cross-sectional direction extend about to that lateral surface of said slot means which is located opposite the respective adjacent cover plate means.

Claim 13

An upholstered body according to claim 8, in which that surface of said stiffening means which faces toward the outside of the respective adjacent cover plate means in cross-sectionwise curved convexly.

Claim 14

An upholstered body according to claim 4, in which said stiffening means extend uninterrupted in a frame-like manner around said spring core.
