Motor vehicle i.e. passenger car, has air-filled free space formed between multi-part porous filling core or air-tight film and roof lining, where filling core and air-tight film are arranged between outer roof membrane and roof lining

摘要

The vehicle has a multi-part porous filling core (10) and an air-tight film (11) that are arranged between an outer roof membrane (1) and a roof lining (2). An air-filled free space (3) is formed between the filling core or the film and the roof lining. An acoustic insulating layer is arranged between the roof membrane and the roof lining and is secured at the filling core or the film. The filling core and the film are three-dimensionally curved and firmly secured at the roof membrane. The filling core is secured on a contact surface of the roof lining.
