Abstract
Official abstract text for this publication.
The present invention provides an automotive soundproofing material capable of providing a high sound absorption performance throughout a wide frequency band. In the automotive soundproofing material, flexible-porous body and sheet-shaped body are formed in a multi-layered structure, and the sheet-shaped body is comprised of a plurality of through holes formed therethrough.
First claim
Opening claim text (preview).
The invention claimed is: 1. A wire harness assembly comprising: an automotive soundproofing material including: a flexible-porous body; and a sheet-shaped body, with the flexible-porous body and the sheet-shaped body in a multi-layered structure; and a wire harness arranged in order of the flexible-porous body, the wire harness and the sheet-shaped body, wherein a portion of the sheet-shaped body where the wire harness is avoided to be arranged is comprised of a plurality of through holes formed therethrough, wherein an aperture ratio of the sheet-shaped body ranges from 3% to 40%. 2. The wire harness assembly according to claim 1 , wherein a surface of the flexible-porous body on a side of the sheet-shaped body is provided with a recess in which the wire harness is to be routed. 3. The wire harness assembly according to claim 1 , wherein the sheet-shaped body is made of vinyl chloride resin, polyethylene, polypropylene, polystyrene or elastomers. 4. The wire harness assembly according to claim 1 , wherein a diameter of each through hole when circularly formed, and/or an equivalent circle diameter of each through hole when not circularly formed ranges from 2.5 mm to 10 mm. 5. The wire harness assembly according to claim 1 , wherein a distance between adjacent two through holes ranges from 10 mm to 18 mm. 6. The wire harness assembly according to claim 1 , wherein the flexible-porous body and the sheet-shaped body is thermal-fusion bonded to each other. 7. The wire harness assembly according to claim 1 , wherein the wire harness is directly contacting both the flexible-porous body and the sheet-shaped body.
