Abstract: A multi-layer acoustically absorptive mat includes a base layer having an exposure hole defined therein. A face layer is disposed adjacent the base layer. An acoustic absorbing layer is interposed between the base layer and the face layer. The acoustic absorbing layer includes an exposed portion extending across the exposure hole wherein the base layer is bonded to the acoustic absorbing layer.

Abstract: Floor drains are provided that can be inserted through floor coverings and through multiple floor panels of a vehicle body. An elongate hollow body terminates at an open distal end and at an open proximate end. A flange extends circumferentially around the open proximate end. One or more resilient members extend circumferentially around, and outwardly from, the body in adjacent spaced-apart relationship with the flange. The resilient members are configured to secure the floor drain within a vehicle floor panel such that the flange compressively engages the floor panel.
