| 20090100603 | Foam spring for pillows, cushions, mattresses or the like and method for manufacturing such a foam spring - A foam spring for use in pillows, cushions, mattresses or the like, the foam spring having a tubular resilient body-made of foam with holes extending inwardly from an outside surface to an inside surface, wherein the tubular body-comprises at least one tubular foam layer and at least one reinforcing layer applied to said foam layer over at least a part of the axial length of the spring. | 04-23-2009 |
| 20090079119 | Foam spring for pillows, cushions, mattresses or the like and method for manufacturing such a foam spring - A foam spring for use in pillows, cushions, mattresses or the like, the foam spring having a tubular resilient body made of foam with holes extending inwardly from an outside surface to an inside surface, wherein the tubular body comprises at least one tubular foam layer and at least one reinforcing layer applied to said foam layer over at least a part of the axial length of the spring. | 03-26-2009 |
| 20090049615 | - A foam spring for use in pillows, cushions, mattresses or the like, the foam spring having a tubular resilient body made of foam with holes extending inwardly from an outside surface to an inside location, wherein the holes extend at a non-perpendicular angle relative to a line perpendicular to the outside surface of the spring at the position of the hole. The foam spring is manufactured by a method which comprises providing interrupted slits along lines extending in the longitudinal direction of a foam layer; cutting a transverse strip out of this foam layer; bending two opposite ends of the strip towards each other; and fixing the two opposite ends into a tubular shape to form the tubular resilient body, wherein the slits are made in a direction forming an angle with the direction perpendicular to the surface of the foamed layer. | 02-26-2009 |
