Patent ID: 8057878

Claim:
A multi-layer fabric structure including: an extending first layer; an extending second layer spaced from the first layer, the first and second layers bounding an interior volume; a baffle layer located within the bounded volume, the baffle layer having a series of undulations that include directional changes to alternately extend toward the first layer and the second layer, the baffle layer being directly attached to the first layer at undulation locations of the baffle layer that extend toward the first layer; and a series of adhesive tape portions located within the interior volume, each tape portion comprising a length of material with adhesive backing on one of its sides, each tape portion being located at an undulation location of the baffle layer that extends toward the second layer, each tape portion being folded into a T-shaped structure so as to provide a baffle layer securing portion and two second layer securing portions, the baffle layer securing portion having a double thickness of material with adhesive backing on one of its sides, each second layer securing portion being secured to the second layer so that the baffle layer securing portion extends from the second layer and is supported by the two second layer securing portions, the baffle layer being secured to the baffle layer securing portion at the undulation locations of the baffle layer that extend toward the second layer and spaced from the second layer.
