An automotive interior trim product, for example a headliner, and method of producing such a product. The product comprising an energy management element which is adapted to be secured to an automotive interior to provide an energy management function. The energy management element is fabricated from a material comprising an array of fused or bonded tube-like members, and comprises a one-piece unitary structure with zones of differing physical properties. The zones of differing physical properties provide different levels of energy management which are matched to the requirements of the interior. The differing physical properties and so differing levels of energy management in the different zones being produced by molding of the unitary element. Alternatively, and/or in addition within the fused array differing types of tube-like members may be used in the differing zones. Such differing types of tubes may have different wall thicknesses, different diameters/dimensions. |
