A multifunctional, lightweight and acoustically optimized interior lining
for the roof of a vehicle is disclosed. The inventive lining comprises an
air permeable core layer, a first stiffening layer, a second stiffening
layer and a decor layer. Said layers are connected to one another by
means of air permeable adhesive layers. The total air flow resistance of
the second stiffening layer, decor layer, and attached adhesive layers,
arranged on the side of the core layer facing the passenger compartment,
is within the range of 500 Nsm.sup.-3>R.sub.t<3500 Nsm.sup.-3. The
total surface area weight of said layers lies in the range of 300 to 800
gr/m.sup.2. A method for producing said lining and the use thereof in a
roof of a vehicle are also disclosed.
