Abstract
The invention describes a foamed material panel, in particular a shaped part composed of one or several foamed material panels. These panels consist of a soft and, if appropriate, elastic foamed material comprising cellular webs and/or cellular walls that are permanently deformed at least in some areas. A central area of the foamed material panel is plastically deformed to a higher volumetric weight than at least one intermediate area of the formed material panel.
Claims21
A foamed material part consisting of at least one foamed material panel of soft foamed material with cellular webs and cellular walls, the foamed material panel comprising
- (a) two surfaces,
- (b) two intermediate areas adjacent the surfaces, and
- (c) a central area between the intermediate areas,
- (1) the cellular webs and cellular walls of the central area being at least partly permanently plastically deformed, major portions of the cellular walls extending substantially parallel to the surfaces of the panel, and
- (2) the central area having a volumetric weight which is higher than that of the intermediate areas.
A foamed material part consisting of at least one foamed material panel of soft foamed material with cellular webs and cellular walls, the foamed material panel comprising
- (a) two surfaces,
- (b) two intermediate areas adjacent the surfaces,
- (c) a central area between the intermediate areas,
- (1) the cellular webs and cellular walls of the central area being at least partly permanently plastically deformed, and
- (2) the central area having a volumetric weight which is higher than that of at least one of the intermediate areas, and
- (d) at least one reinforcing element inserted in the central area of the foamed material panel.
A foamed material part consisting of at least one foamed material panel of soft foamed material with cellular webs and cellular walls, the foamed material panel comprising
- (a) two surfaces,
- (b) two intermediate areas adjacent the surfaces,
- (c) a central area between the intermediate areas,
- (1) the cellular webs and cellular walls of the central area being at least partly permanently plastically deformed, and
- (2) the central area having a volumetric weight which is higher than that of at least one of the intermediate areas, and
- (d) at least one reinforcing element inserted in at least one of the intermediate areas of the foamed material panel.
A foamed material part consisting of at least one foamed material panel of soft foamed material with cellular webs and cellular walls, the foamed material panel comprising
- (a) two surfaces,
- (b) two intermediate areas adjacent the surfaces,
- (c) a central area between the intermediate areas,
- (1) the cellular webs and cellular walls of the central area being at least partly permanently plastically deformed, and
- (2) the central area having a volumetric weight which is higher than that of at least one of the intermediate areas, and
- (d) at least one reinforcing element consisting of an alloyed steel.
