Abstract
The invention relates to an interior lining for a motor vehicle, with a sliding or panoramic roof, which comprises a roof liner and a stiffening frame which is attached to the roof liner, and an opening in the roof liner, which delimits, frames and stabilizes the sliding or panoramic window. The roof liner is constructed in several layers, which comprise at least one core layer and one cover layer. The stiffening frame is produced from a fiber-reinforced composite material, which contains organic synthetic polymer fibers, carbon fibers or natural fibers, or mixtures of these fibers, and a binder made from a duroplastic or thermoplastic material. The surface weight and the bending stiffness of the stiffening frame are greater than those of the roof liner structure, preferably by at least 50%.
