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.

First claim

What is claimed:

1. A load compartment cover for vehicles having a load compartment that is provided between the rear seats and a tailgate, said load compartment cover comprising:
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, characterized in that the sound-absorbing partition is formed from multiple thin sheets that are arranged spaced apart one above the other, wherein at least one of the thin sheets is provided with a micro perforation and that only one air cushion is provided between the thin sheets.

2. The load compartment cover as claimed in claim 1 , characterized in that the partition is formed from two thin sheets that are arranged spaced apart one above the other.

3. The load compartment cover as claimed in claim 2 , characterized in that a common cassette is provided to receive the thin sheets and the thin sheets are selectively wound or unwound in said cassette.

4. The load compartment cover as claimed in claim 3 , characterized in that a separate spring-loaded winding spool is provided in the cassette for each thin sheet, wherein the winding spools are arranged spaced apart one above the other.

5. The load compartment cover as claimed in claim 3 , characterized in that a single spring-loaded winding spool is provided in the cassette and the thin sheets can be wound and unwound jointly on said winding spool and that at least one spacer is arranged between the thin sheets on the or near the exit of the cassette.

6. The load compartment cover as claimed in claim 5 , characterized in that a common hand grip is provided so as to actuate the thin sheets.

7. The load compartment cover as claimed in claim 6 , characterized in that the thin sheets are fastened to the common hand grip spaced apart one above the other.

8. The load compartment cover as claimed in claim 3 , characterized in that a single spring-loaded winding spool is arranged in the cassette and it is possible to wind or unwind a first end of the thin sheet on said winding spool, that a second end of the thin sheet is fastened to the cassette in a spacing below or above the first end, and that the thin sheet is guided over a deflecting roller that is arranged above a hand grip.

9. The load compartment cover as claimed in claim 8 , characterized in that the thin sheet is embodied from two part pieces that are embodied so as to be different over the length that said thin sheet that can be drawn out.

10. The load compartment cover as claimed in claim 9 , characterized in that the winding spools comprise self-stopping drives.

11. The load compartment cover as claimed in claim 10 , characterized in that the thin sheets comprise a thickness of below 1 mm and in particular a thickness of 0.05 to 0.4 mm.

12. The load compartment cover as claimed in claim 11 , characterized in that the micro perforation of a thin sheet comprises variations by means of at least one change in relation to the spacing of the holes, the shape of the holes, the diameter of the holes or the arrangement of the holes on the thin sheet.

13. The load compartment cover as claimed in claim 12 , characterized in that the spacings of the holes of the micro perforation that is provided in the thin sheets is between 2 and 10 mm.

14. The load compartment cover as claimed in claim 13 , characterized in that the spacing between the thin sheets or between the ends of the thin sheet can be varied.

15. The load compartment cover as claimed in claim 14 , characterized in that the cassette that receives the thin sheets is configured to be adjusted in terms of its height relative to the base of the load compartment.

16. The load compartment cover as claimed in claim 1 , characterized in that the micro perforation of a thin sheet comprises variations by means of at least one change in relation to the spacing of the holes, the shape of the holes, the diameter of the holes or the arrangement of the holes on the thin sheet.

17. The load compartment cover as claimed in claim 16 , characterized in that the spacings of the holes of the micro perforation that is provided in the thin sheets is between 2 and 10 mm.
