Patent ID: 7884038

Claim:
A lining element, in particular an interior lining and/or covering element, for motor vehicles, comprising: a decorative layer; and a support layer structure attached to the decorative layer, the support layer structure including an intermediate layer that is arranged between two support layers and mechanically connected to the support layers, the intermediate layer having a non-uniform thickness and/or non-uniform mass per unit area and/or non-uniform air permeability, wherein an air permeability and/or density and/or a mass per unit area of the support layer structure are preset for controlling acoustic properties by matching the thickness, and/or the mass per unit area, and/or the air permeability of the lining element in zones, or over an entire surface, to sound emissions which are to be absorbed, with increased thickness and/or mass per unit area and/or reduced air permeability in the zones that have greater sound emissions to absorb.
