Abstract

A foam moulding is proposed having an integrally moulded anchoring element, by means of which the moulding is capable of being connected to other components, in particular to a cover, the anchoring element being a filament (2) of organic material extending parallel to the surface of the cushion.

Claims

1. Foam moulding with an integrally moulded anchoring element for connecting the moulding to one or more other components, wherein the anchoring element comprises a filament (2) of organic material extending parallel to the surface of the cushion.

2. A foam moulding according to claim 1 with a polyhydric alcohol as educt which, as a result of molecular cross-linkages accompanied by cleavage of hydroxyl groups, reacts with other reactive components to form the foam, wherein the surface of the anchoring element presents hydroxyl groups prior to being integrally moulded within the foam.

3. A foam moulding according to claim 1, wherein the component is fastened to the anchoring element at a plurality of points.

4. A foam moulding according to claim 1, wherein the surface of the anchoring element has a relief structure.

5. A foam moulding according to claim 1, wherein the anchoring element comprises natural fibers.

6. A foam moulding according to claim 5, wherein the anchoring element comprises one of hemp or jute.

7. A foam moulding according to claim 1, wherein the foam is polyurethane.

8. A foam moulding according to claim 1, wherein the filament extends in the form of a closed traverse.

9. A process for producing a foam moulding according to claim 1 with a mould that is capable of being filled out with foam and comprises a receiving device for fixing the anchoring element, the process comprising the steps of:

clamping the filament (2) of organic material under tension into the receiving device,

filling-out of the mould with foam, and

removal of the moulding.

10. A process according to claim 9, wherein the filament (2) is drawn off from a roll and is cut to size one of prior to and after the filing-out with foam.
