Abstract
Abstract Filling support material used in furniture, such as beds and chairs within covering made from resilient material such as plastic having planar form and parallel elongate cavities in plural layers to provide spring like action. The filling structure can be modular and interengaged by lugs and sockets or suitable bonding. Within the elongate cavities load bearing ribs can be included to provide additional firmness.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
122 words
Resilient upholstery filling comprising: plastic, or the like, planar shaped material provided with upper, lower and side wall surfaces and internal cavities extending parallel to one another in the longitudinal direction of said filling, said parallel cavities situated in a number of layers between upper and lower surfaces; interconnected walls laterally bounding and defining said cavities consisting of a homogeneous plastic material having elastic but incompressible properties, at least portions of said interconnected walls disposed at an inclination in relation to the outside surfaces of the upholstery, being preferentially subjected to bending stress on loading of the upholstery; and additional wall means disposed substantially parallel to the upper and lower surfaces of the upholstery filling extend between two sidewalls of the latter.
Claim 2
Dependent Claim
122 words
Resilient upholstery filling comprising: plastic, or the like, planar shaped material provided with upper, lower and side wall surfaces and internal cavities extending parallel to one another in the longitudinal direction of said filling, said parallel cavities situated in a number of layers between upper and lower surfaces; interconnected walls laterally bounding and defining said cavities consisting of a homogeneous plastic material having elastic but incompressible properties, at least portions of said interconnected walls disposed at an inclination in relation to the outside surfaces of the upholstery, being preferentially subjected to bending stress on loading of the upholstery; and additional wall means disposed substantially parallel to the upper and lower surfaces of the upholstery filling extend between two sidewalls of the latter.
Claim 3
Dependent Claim
16 words
Upholstery filling as defined in claim 1, wherein said planar material consists of extruded plastic material.
Claim 4
Dependent Claim
30 words
Upholstery filling as defined in claim 1, comprising: an assembly of a plurality of interengaged elements of said planar shaped material; and interengaging means on adjacent portions of said elements.
Claim 5
Dependent Claim
160 words
Resilient upholstery filling comprising: plastic, or the like, planar shaped material provided with upper, lower and side wall surfaces and internal cavities extending parallel to one another in the longitudinal direction of said filling, said parallel cavities situated in a number of layers between upper and lower surfaces; interconnected walls laterally bounding and defining said cavities consisting of a homogeneous plastic material having elastic but incompressible properties, at least portions of said interconnected walls disposed at an inclination in relation to the outside surfaces of the upholstery, being preferentially subjected to bending stress on loading of the upholstery; and elongate flat loading ribs disposed within at least a portion of said cavities so their elongate dimension extends parallel with the disposition of said cavities, each said loading rib being fixedly mounted to the internal wall surface defining an associated said cavity and disposed so it extends into the associated said cavity with its transverse dimension perpendicular to said upper surface.
Claim 6
Dependent Claim
160 words
Resilient upholstery filling comprising: plastic, or the like, planar shaped material provided with upper, lower and side wall surfaces and internal cavities extending parallel to one another in the longitudinal direction of said filling, said parallel cavities situated in a number of layers between upper and lower surfaces; interconnected walls laterally bounding and defining said cavities consisting of a homogeneous plastic material having elastic but incompressible properties, at least portions of said interconnected walls disposed at an inclination in relation to the outside surfaces of the upholstery, being preferentially subjected to bending stress on loading of the upholstery; and elongate flat loading ribs disposed within at least a portion of said cavities so their elongate dimension extends parallel with the disposition of said cavities, each said loading rib being fixedly mounted to the internal wall surface defining an associated said cavity and disposed so it extends into the associated said cavity with its transverse dimension perpendicular to said upper surface.
Claim 7
Dependent Claim
22 words
Upholstery filling as defined in claim 4, wherein said walls bounding a cavity at least partially form said walls of adjacent cavities.
Claim 8
Dependent Claim
16 words
Upholstery filling as defined in claim 4, wherein said planar material consists of extruded plastic material.
Claim 9
Dependent Claim
39 words

Claim 10
Dependent Claim
51 words
Upholstery filling as defined in claim 7, wherein the cavities associated with said loading ribs have at least two adjoining cavity walls inclined relative to each other to provide an elongate trough shaped wall surface parallel to and providing a receiving abutment for the free edge of the associated loading rib.
Claim 11
Dependent Claim
14 words
Upholstery filling as defined in claim 4, wherein said cavities have a polygonal cross-section.
Claim 12
Dependent Claim
