| 摘要 |
The present invention relates to a sound-insulating composite part, particularly for motor vehicles, comprising a heavy layer ( 7 ) and at least one layer ( 8 ) made of open-pored, elastic absorbing material. Multiple webs ( 9 ) are molded onto the heavy layer ( 7 ), which are made of the material of the underlay, the underlay material forming the webs ( 9 ) being pressed into and/or through the absorber layer ( 8 ). The webs ( 9 ) divide the absorber layer into multiple absorber areas ( 11 ) of different sizes and different thicknesses, which project like cushions in relation to the webs ( 9 ). The composite part may preferably be implemented as a floor covering of a motor vehicle, the absorber layer equalizing structure-related height differences, e.g., depressions in underlying vehicle body sheet metal.
