SANDWICH ELEMENT
A sandwich element includes a base element and a structural element. The structural element forms a soft touch surface of the sandwich element, the structural element contains at least two functional layers, one of the functional layers is a soft touch layer and another of the functional layers is a decorative layer forming the soft touch surface. The soft touch layer is disposed between the decorative layer and the base element and a fire-retardant layer is disposed in the interior of the sandwich element.
1 . A sandwich element, comprising:
an interior of the sandwich element;
a fire-retardant layer disposed in said interior;
a base element; and
a structural element;
said structural element forming a soft touch surface of the sandwich element;
said structural element containing at least two functional layers;
one of said functional layers being a soft touch layer and another of said functional layers being a decorative layer forming said soft touch surface; and
said soft touch layer being disposed between said decorative layer and said base element.
2 . The sandwich element according to claim 1 , wherein said fire-retardant layer is disposed between said base element and said structural element.
3 . The sandwich element according to claim 1 , wherein said base element is a sandwich structure.
4 . The sandwich element according to claim 3 , wherein said sandwich structure is a fiber composite element or a monolithic or thermoplastic deep-drawn element.
5 . The sandwich element according to claim 1 , which further comprises an adhesive or an adhesive layer bonding at least two of said functional layers to one another.
6 . The sandwich element according to claim 1 , wherein:
said base element is coated with said fire-retardant layer; and
an adhesive or an adhesive layer bonds said structural element onto said base element.
7 . The sandwich element according to claim 1 , wherein said base element extends in a planar manner along an extension surface, said base element has a flat side extending along said extension surface, and said structural element is applied to said flat side.
8 . The sandwich element according to claim 1 , wherein said base element extends in a planar manner along an extension surface, said base element has a flat side extending along said extension surface, and said fire-retardant layer is applied to said flat side.
9 . The sandwich element according to claim 1 , wherein said fire-retardant layer is a coating layer.
10 . The sandwich element according to claim 1 , wherein said fire-retardant layer is an intumescent fire-retardant layer.
11 . The sandwich element according to claim 10 , wherein said intumescent fire-retardant layer at least one of contains expandable graphite or is an ablative fire-retardant layer.
12 . The sandwich element according to claim 11 , wherein said ablative fire-retardant layer contains aluminum hydroxide.
13 . The sandwich element according to claim 1 , wherein the sandwich element is at least a section of an interior compartment structure of an interior compartment.
