Abstract
Abstract The upholstery element is adapted to provide a resiliently yielding support and comprises individual rod-shaped resilient inserts spaced apart in the direction of one dimension of the upholstery element and extending in said upholstery element in a longitudinal direction which is transverse to the direction in which they are spaced apart, connecting layers of foam disposed between said inserts and constituting the only connection between said inserts and adapted to take up forces which occur between the inserts, said connecting layers joining said inserts in a common composite body, and covering layers of foam adjoining said connecting layers and covering said inserts in those surface areas which are not covered by the connecting layers.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
227 words
A three-dimensional cushioning member for elastically supporting a load, such as a cushion for furniture to sit or lie on comprising, in combination a plurality of elongated resilient rod-shaped support inserts disposed in spaced parallel relationship to one another, each said insert extending in its elongated direction for an extent substantially equal to the corresponding dimension of the cushioning member, a monolithic body of foam completely enclosing the surfaces of each of said inserts in a shape determining the external configuration of the cushioning member, said body of foam having a first surface against which a load is normally applied to the cushioning member, said body of foam forming the sole connection between said rod-shaped inserts, the part of the body of foam extending from the surface of said inserts in the direction of the first surface of the cushioning body having a greater thickness than the part of said body of foam extending in the opposite direction from the opposite surface of said inserts, and pin-shaped seating elements extending from the exterior surface of said body foam opposite the first surface of said body of foam and in the direction of said first surface into contact with the opposite ends of said inserts, the smallest dimension between said inserts and the exterior surface of said body of foam is located at the ends of said inserts.
Claim 2
Dependent Claim
227 words
A three-dimensional cushioning member for elastically supporting a load, such as a cushion for furniture to sit or lie on comprising, in combination a plurality of elongated resilient rod-shaped support inserts disposed in spaced parallel relationship to one another, each said insert extending in its elongated direction for an extent substantially equal to the corresponding dimension of the cushioning member, a monolithic body of foam completely enclosing the surfaces of each of said inserts in a shape determining the external configuration of the cushioning member, said body of foam having a first surface against which a load is normally applied to the cushioning member, said body of foam forming the sole connection between said rod-shaped inserts, the part of the body of foam extending from the surface of said inserts in the direction of the first surface of the cushioning body having a greater thickness than the part of said body of foam extending in the opposite direction from the opposite surface of said inserts, and pin-shaped seating elements extending from the exterior surface of said body foam opposite the first surface of said body of foam and in the direction of said first surface into contact with the opposite ends of said inserts, the smallest dimension between said inserts and the exterior surface of said body of foam is located at the ends of said inserts.
Claim 3
Dependent Claim
218 words
A three-dimensional cushioning member for elastically supporting a load, such as a cushion for furniture to sit or lie on, comprising, in combination, a plurality of elongated resilient rod-shaped support inserts disposed in spaced parallel relationship to one another and each said insert extending in its elongated direction for an extent substantially equal to the width dimension of the cushioning member, said inserts arranged in the form of leaf springs and being spaced apart in the direction transverse to the width dimension of the cushioning member, a monolithic body of foam completely enclosing the surfaces of each of said inserts and having a shape determining the external configuration of the cushioning member, said body of foam forming the sole connection between said rod-shaped inserts, said body of foam having a first surface against which the load is normally applied, a seating element located at each of the ends of said inserts and having a pin-like shape, said seating elements extending from the surfaces of said inserts disposed in the opposite direction from the surface thereof facing toward the first surface of said body of foam and extending therefrom to the adjacent surface of said body of foam disposed opposite to the first surface of said body of foam, and the body of foam being a cold cured foam.
Claim 4
Dependent Claim
218 words
A three-dimensional cushioning member for elastically supporting a load, such as a cushion for furniture to sit or lie on, comprising, in combination, a plurality of elongated resilient rod-shaped support inserts disposed in spaced parallel relationship to one another and each said insert extending in its elongated direction for an extent substantially equal to the width dimension of the cushioning member, said inserts arranged in the form of leaf springs and being spaced apart in the direction transverse to the width dimension of the cushioning member, a monolithic body of foam completely enclosing the surfaces of each of said inserts and having a shape determining the external configuration of the cushioning member, said body of foam forming the sole connection between said rod-shaped inserts, said body of foam having a first surface against which the load is normally applied, a seating element located at each of the ends of said inserts and having a pin-like shape, said seating elements extending from the surfaces of said inserts disposed in the opposite direction from the surface thereof facing toward the first surface of said body of foam and extending therefrom to the adjacent surface of said body of foam disposed opposite to the first surface of said body of foam, and the body of foam being a cold cured foam.
Claim 5
Dependent Claim
56 words
A three-dimensional cushioning member, as set forth in claim 2, wherein the thickness of said body of foam from the first surface thereof to the adjacent surface of said inserts is greater than the thickness between the opposite surfaces of said inserts and the surface of said body of Foam disposed opposite to its first surface.
Claim 6
Dependent Claim
50 words
A three-dimensional cushioning member, as set forth in claim 3, wherein the cushioning member being subjected normally to varying loads across its surface, and the width and profile dimensions of said inserts being determined by its location within said body of foam and the normal load applied at said location.
