First Claim
Patent Images
1. A sound insulation system for use within a vehicle, the sound insulation system consisting essentially of:
- a layer of fibrous padding material having a first surface and an opposite second surface, the first surface including multiple spaced apart recesses, the second surface having a substantially flat surface portion that extends over two adjacent recesses of the first surface; and
a cover layer attached to the second surface of the layer of fibrous padding material;
wherein the recesses of the first surface are configured to define multiple voids when the sound insulation system is mounted in the vehicle, thereby enhancing acoustical performance of the sound insulation system.

Abstract
A sound insulation system for use with a vehicle includes a layer of fibrous padding material having a first surface and an opposite second surface. The first surface includes multiple spaced apart recesses. The second surface includes a substantially flat surface portion that extends over two adjacent recesses. The multiple recesses are configured to define multiple voids when the sound insulation system is mounted in the vehicle, thereby enhancing acoustical performance of the sound insulation system.

9. A flooring system for positioning proximate a floor pan of a vehicle, the flooring system consisting essentially of:
-
a fibrous layer having multiple vertically lapped folds that cooperate to define a first surface and an opposite second surface of the fibrous layer, the first surface being adapted to face toward the floor pan and having multiple recesses, the second surface having a shape that generally conforms with the floor pan, the second surface further having a substantially flat surface portion that extends over at lest two adjacent recesses of the first surface; and a cover layer attached to the second surface of the fibrous layer; wherein the multiple recesses are configured to define multiple voids when the flooring system is mounted in the vehicle, thereby enhancing acoustical performance of the flooring system.

10. A method of forming a sound insulation system for use within the interior of a vehicle, the method consisting essentially of:
-
positioning a layer of fibrous padding material having a first surface and an opposite second surface between first and second mold sections of a mold, the first mold section including a first mold surface having multiple spaced apart projections; and compressing the layer of fibrous padding material between the mold sections such that the first mold surface forms multiple spaced apart recesses in the first surface of the layer of fibrous padding material; wherein the recesses are configured to define multiple voids when the sound insulation system is installed in the vehicle. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)
