Abstract

A method for producing a vehicle interior component includes placing a polymeric cushion blank in a mold having a plurality of apertures and a mold cavity. The method may include the step of passing a first fluid having a first predetermined temperature through at least some of the apertures and through the cushion blank to heat the cushion blank to a compliant, non-liquid state. The method may also include passing a second fluid having a second predetermined temperature lower than the first predetermined temperature through the mold and through the cushion blank to cool cushion blank to a non-compliant state.

First claim

What is claimed is:

1. A method for producing a vehicle interior component, comprising:
placing at least a portion of a polymeric material in a tool comprising an open area of a predetermined shape;
applying heat to the polymeric material through the open area to form a cut line comprising the predetermined shape to form a cushion blank;
placing the cushion blank in a mold comprising a cavity with a cavity shape, wherein the mold comprises a top portion comprising a first plurality of apertures and a bottom portion comprising a second plurality of apertures;
passing a first fluid comprising a first predetermined temperature through the first plurality of apertures in the top portion of the mold and through the cushion blank to heat the cushion blank to a compliant, non-liquid state such that the cushion blank assumes the cavity shape; and
passing a second fluid comprising a second predetermined temperature lower than the first predetermined temperature through the second plurality of apertures in the bottom portion of the mold and through the cushion blank to cool cushion blank to a non-compliant state.

2. The method of claim 1 , wherein:
the tool further comprises a closed area, and the polymeric material is accessible through the open area for applying heat, and
a first portion of the polymeric material is separated from a second portion of the polymeric material based on heat applied to the polymeric material through the open area.

3. The method of claim 2 , wherein the first portion of the polymeric material is the cushion blank, and wherein the cushion blank comprising at least the portion of the polymeric material in a solid state.

4. The method of claim 2 , further comprising applying cooling to the polymeric material through the open area along the cut line.

5. The method of claim 1 , wherein the first fluid and the second fluid are the same.

6. The method of claim 1 , wherein the polymeric material is a stranded-mesh material.

7. The method of claim 1 , wherein at least one of the first fluid or the second fluid is air.

8. A method for producing a vehicle interior component, comprising:
placing at least a portion of a polymeric material in a tool comprising an open area of a predetermined shape;
applying heat to the polymeric material through the open area to form a cut line comprising the predetermined shape to form a cushion blank;
placing the cushion blank in a mold comprising a top portion and a bottom portion, wherein the top portion comprises a first plurality of apertures and the bottom portion comprises a second plurality of apertures;
passing a first fluid having a first predetermined temperature through the first plurality of apertures in the top portion and through the cushion blank to heat the cushion blank to a compliant, non-liquid state; and
passing a second fluid having a second predetermined temperature lower than the first predetermined temperature through the second plurality of apertures in the bottom portion of the mold and through the cushion blank to cool cushion blank to a non-compliant state.

9. The method of claim 8 , further comprising passing the first fluid through the first plurality of apertures and through the cushion blank for a predetermined period of time before passing the second fluid through the mold and through the cushion blank.

10. The method of claim 8 , wherein the first fluid and the second fluid are different fluids.

11. The method of claim 8 , wherein at least one of the first fluid or the second fluid is a liquid.

12. The method of claim 8 , further comprising:
cooling the polymeric material through the open area along the cut line, wherein the tool further comprises a closed area and the polymeric material is accessible through the open area to one of cool or heat the polymeric material.

13. The method of claim 12 , further comprising separating a first portion of the polymeric material from a second portion of the polymeric material along the cut line.

14. The method of claim 13 , wherein the cushion blank comprises the first portion of the polymeric material.

15. A method for producing a vehicle interior component, comprising:
placing at least a portion of a polymeric material in a tool comprising an opening of a linear shape;
applying heat to the polymeric material through the opening to form a cut line comprising the linear shape to form a cushion blank;
placing the cushion blank comprising the polymeric material in a solid state in a mold comprising a cavity, wherein the mold comprises a top portion with a first plurality of apertures and a bottom portion with a second plurality of apertures;
introducing into the cushion blank a first fluid flow comprising a first predetermined temperature through the first plurality of apertures, such that the cushion blank is heated to a compliant, non-liquid state in the mold; and
introducing into the cushion blank a second fluid flow comprising a second predetermined temperature lower than the first predetermined temperature through the first plurality of apertures, such that the cushion blank is cooled to a non-compliant state.

16. The method of claim 15 , wherein:
a first portion of the polymeric material inside the opening is separated from a second portion of the polymeric material outside the opening based on the applied heat.

17. The method of claim 16 , wherein the cushion blank comprises the portion of the polymeric material comprising having an outside perimeter defined by the linear shape.

18. The method of claim 15 , further comprising maintaining the first fluid flow for a predetermined period of time before introducing into the cushion blank the second fluid flow.

19. The method of claim 15 , wherein at least one of the first fluid flow or the second fluid flow is a gas.

20. The method of claim 19 , wherein at least one of the first fluid flow or the second fluid flow is an airflow.
