摘要：To reinforce a panel-shaped sound-insulating and absorption element for lining the interior of motor vehicles, in particular for lining the foot space and the partition wall region, consisting essentially of a layer of polyurethane (PUR) foam, such that by virtue of the reinforcement, in particular the sound-insulating and absorption behaviour of the panel-shaped element consisting of the two materials can be influenced as required, it is proposed that the foam layer (1) is covered at least partly by a layer (2) of a material forming three-dimensional grid structures with open compartment cells. <IMAGE>
