Rear seat cushion sound reduction mat
First Claim
1. A sound blocking rear seat assembly for an automotive vehicle, the rear seat assembly comprising:
- a seat back located adjacent to and extending generally upward from a seat bottom, the seat bottom defining a width extending laterally relative to a longitudinal axis of the vehicle and further defining at least two seating locations for passengers in the vehicle, the seat bottom further including a seat base extending substantially the width of the seat bottom and beneath each of the seating locations, a sound-blocking layer incorporated into the seat bottom, the sound blocking layer being a nonporous resilient layer extending substantially continuously over the width of the seat bottom, a resilient seat cushion also incorporated into the seat bottom, and a trim layer located over the seat cushion layer, wherein the sound-blocking layer provides a decrease in sound transmission of between about 0.1-2 dB as compared to a seat bottom of the same construction without the sound-blocking layer.

Abstract
A sound blocking rear seat assembly for an automotive vehicle. The rear seat assembly includes a seat back adjacent to a seat bottom. The seat bottom also defines at least two passenger seating locations. A seat base of the seat bottom extends the width of the seat assembly and has a non-planar three dimensional contoured upper surface. A nonporous resilient sound blocking layer has a shape substantially conforming to the upper surface of the seat base and is located over the seat base such that it extends substantially continuously and uninterruptedly over the width of the seat assembly. Positioned over the sound blocking layer is a resilient seat cushion, and a trim layer is located over the seat cushion layer.

13. A sound blocking assembly for an automotive vehicle, the sound blocking assembly comprising:
an automotive interior component defining a width extending laterally relative to a longitudinal axis of the vehicle, the interior component further including a base layer material extending substantially the width of the interior component, the base layer material having a non-planar three dimensional contoured surface, a sound-blocking layer attached the base layer material, the sound blocking layer being a nonporous resilient layer extending substantially continuously over the base layer material, wherein the sound-blocking layer provides a decrease in sound transmission of between about 0.1-2 dB as compared to an interior component of the same construction without the sound-blocking layer. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
