Abstract
A cavity filler for use in a hollow pillar of a vehicle. The cavity filler includes a carrier having a generally planar upper surface, an expandable foam mounted to the carrier wherein the expandable foam is mounted to the carrier around a peripheral edge of the carrier. The invention further includes a flange connected to the expandable foam (also made of the expandable foam) wherein the flange extends away from and generally parallel with the planar upper surface of the carrier. The extension and flange of the expandable foam are operable to extend the expandable foam to ensure a full filling of the expandable foam after the heat treating process. The fully occupied hollow cavity of the pillar with the expandable foam blocks the transmission of noise from the engine, wind and/or road noise through the pillars to the interior vehicle cabin.
