Abstract

A shaped body includes at least one spring and at least one foam section. An uppermost section of the foam section is attached to an uppermost section of the at least one spring and a lowest section of the foam section is attached to the lowest section of the at least one spring. The uppermost section is attached by affixation through a top plate to the at least one spring and the lowest section is attached by affixation through a bottom plate to the at least one spring. The at least one spring is arranged adjacent to the at least one foam section. The top plate and the bottom plate are sufficiently mechanically firm to generate parallel behavior of the at least one spring and the at least one foam section.

Claims (22)

1. A shaped body, comprising:

at least one spring and at least one foam section, whereas an uppermost section of the at least one foam section is attached to an uppermost section of the at least one spring, and a lowest section of the at least one foam section is attached to the lowest section of the at least one spring;

wherein the uppermost section of the at least one foam section is attached by affixation through a top plate to the at least one spring;

wherein the lowest section of the at least one foam section is attached by affixation through a bottom plate to the at least one spring;

wherein the top plate and the bottom plate are sufficiently mechanically firm to generate parallel behavior of the at least one spring and the at least one foam section; and

wherein the at least one spring is arranged adjacent to the at least one foam section.

2. The shaped body of claim 1 , wherein the shaped body comprises at least two springs and wherein the at least one foam section is arranged adjacent to and between the at least two springs.

3. The shaped body of claim 2 , wherein the uppermost section of the at least one foam section is attached by affixation through a top plate to the uppermost sections of the at least two springs and the lowest section of the at least one foam section is attached by affixation through a bottom plate to the lowest sections of the at least two springs, wherein the top plate and the bottom plate are sufficiently mechanically firm to generate parallel behavior of the at least two springs and the at least one foam section.

4. The shaped body of claim 1 , wherein the shaped body comprises at least two foam sections and wherein the at least one spring is arranged adjacent to and between the at least two foam sections.

5. The shaped body of claim 4 , wherein the uppermost section of the at least one spring is attached by affixation through a top plate to the uppermost sections of the at least two foam sections and the lowest section of the at least one spring is attached by affixation through a bottom plate to the lowest sections of the at least two foam sections, wherein the top plate and the bottom plate are sufficiently mechanically firm to generate parallel behavior of the at least two foam sections and the at least one spring.

6. The shaped body of claim 1 , wherein a softness of the at least one foam section is temperature dependent.

7. The shaped body of claim 6 , further comprising a temperature-regulating device for changing the temperature-dependent foam section.

8. The shaped body of claim 7 , further comprising a control device for the temperature regulating device adapted to adjust the firmness of one of the at least one foam section by alteration of temperature of the at least one foam section.

9. The shaped body of claim 1 , wherein the at least one foam section further comprises at least one of a horizontal channel or a vertical channel.

10. The shaped body of claim 1 , further comprising a plurality of sensors to measure pressure applied to a surface of the shaped body.

11. The shaped body of claim 1 , wherein the top plate is one or more of metal and plastic, and wherein the bottom plate is one or more of metal and plastic.

12. A cushion, bed, mattress or pillow comprising a shaped body, the shaped body comprising:

at least one spring and at least one foam section, whereas an uppermost section of the at least one foam section is attached to an uppermost section of the at least one spring, and a lowest section of the at least one foam section is attached to the lowest section of the at least one spring;

wherein the uppermost section of the at least one foam section is attached by affixation through a top plate to the at least one spring;

wherein the lowest section of the at least one foam section is attached by affixation through a bottom plate to the at least one spring;

wherein the top plate and the bottom plate are sufficiently mechanically firm to generate parallel behavior of the at least one spring and the at least one foam section; and

wherein the at least one spring is arranged adjacent to the at least one foam section.
