Abstract
Official abstract text for this publication.
The present invention relates to an interior trim component with a three-dimensional shape, wherein the interior trim component is produced from a single nonwoven material and includes a first surface and a second surface. At least one region that forms the first surface, and at least one first section and at least one second section, each of which forming a part of the second surface, wherein the first section has a first section hardness, H 1 and the second section has a second section hardness, H 2 , and the first section hardness H 1 and the second section hardness H 2 are different.
First claim
Opening claim text (preview).
What is claimed is: 1 . An interior trim component with a three-dimensional shape for a motor vehicle, comprising, a single nonwoven material including, a first surface and a second surface, a first section and a second section, each of which forming a part of the second surface, wherein the first surface and the second surface are located opposite to each other, the second surface forms the visible side of the interior trim component, said first section has a first section hardness and the second section has a second section hardness, such that the first section hardness and the second section hardness are different, wherein the interior trim component has one single region which forms the entire first surface, wherein the first section hardness is greater than the second section hardness, and the single region has a constant region hardness which is equal to the first section hardness. 2 . The interior trim component according to claim 1 , wherein the first section has a first density and the second section has a second density, said first density is between 0.6 g/cm 3 and 1 g/cm 3 and said second density is between 0.1 g/cm 3 and 0.6 g/cm 3 . 3 . The interior trim component according to claim 1 , wherein the first section has a first surface roughness and the second section has a second surface roughness, said first surface roughness and said second surface roughness are different. 4 . The interior trim component according to claim 1 , wherein the nonwoven material is a needled nonwoven material. 5 . The interior trim component according to claim 4 , wherein the needled nonwoven material comprises thermoplastic fibers having different melting temperatures. 6 . The interior trim component according to claim 5 , wherein the thermoplastic fibers are composed of polyester. 7 . The interior trim component according to claim 1 , wherein the nonwoven material comprises bi-component fibers. 8 . The interior trim component according to claim 7 , wherein the proportion by weight of the thermoplastic fibers to the bi-component fibers is between 70:30 and 30:70. 9 . An interior trim component with a three-dimensional shape for a motor vehicle, comprising, a single nonwoven material including, a first surface and a second surface, a first section and a second section, each of which forming a part of the second surface, wherein the first surface and the second surface are located opposite to each other, the second surface forming the visible side of the interior trim component, said first section has a first section hardness and said second section has a second section hardness, such that the first section hardness and the second section hardness are different, wherein the interior trim component has one single region forming the entire first surface, wherein said first section hardness is greater than the second section hardness, and the single region has a constant region hardness equal to the first section hardness, wherein said first section has a first density and the second section has a second density, said first density is between 0.6 g/cm 3 and 1 g/cm 3 and said second density is between 0.1 g/cm 3 and 0.6 g/cm 3 . 10 . An interior trim component with a three-dimensional shape for a motor vehicle, comprising, a single nonwoven material including, a first surface and a second surface, a first section and a second section, each of which forming a part of the second surface, wherein the first surface and the second surface are located opposite to each other, the second surface forming the visible side of the interior trim component, said first section has a first section hardness and said second section has a second section hardness, such that the first section hardness and the second section hardness are different, wherein the interior trim component has one single region which forms the entire first surface, wherein the first section hardness is greater than the second section hardness, and the region has a constant region hardness which is equal to the first section hardness, said first section has a first section roughness and the second section has a second surface roughness, said first surface roughness and said second surface roughness are different.
