Abstract
The invention relates to a load compartment cover having sound-absorbing characteristics. A load compartment is provided between the rear seats and a tailgate. The load compartment cover is embodied from a sound-absorbing partition that is arranged in a space above a base of the load compartment and is embodied from a material that is in part permeable to sound waves. A load compartment cover of this type is to be easily handled in practice and is not to comprise any disadvantages associated with known load compartment covers. This is achieved by virtue of the fact that the partition is formed from multiple, preferably two, thin sheets that are arranged spaced apart one above the other. The thin sheets are provided with a micro perforation and only one air cushion is provided between the thin sheets.
