Abstract
A method and apparatus for manufacturing an air controllably permeable, water repellent, acoustic absorbing door water shield for attachment to a vehicle door. The water shield is formed of a first layer constructed of a water repellant, air restrictive non woven scrim which is joined to a second layer formed of a lofted, non-woven fiber pad. The first layer has an air permeability greater than zero. Varying the characteristics of the first and second layers optimizes the acoustic absorption range of the door water shield.
Claims19
An acoustically active watershield mountable on an automotive vehicle door in an interior cavity defined therein, the watershield comprising:
- a first layer having a first surface and a second surface, the first surface configured to be oriented to face an outwardly oriented panel of the automatic vehicle door, the first layer composed of a hydrophobic, air restrictive, fluid repellant scrim;
- a second layer in laminated relationship to the second face of the first layer, the second layer having a first face in laminated contact with the first layer and an opposed second face, the second layer composed of one of an open-cell foam or a lofted fiber material.
A vehicle door assembly comprising:
- an outwardly oriented panel;
- an inwardly oriented panel;
- an interior trim panel overlaying the inwardly oriented panel;
- and
- a vehicle door shield positioned between the inwardly oriented panel and the interior trim panel, the vehicle door shield consisting of an inwardly oriented layer composed of a lofted fiber pad and an outwardly oriented layer formed of a non-woven breathable, hydrophobic, fluid-repellant scrim, in laminated contact thereto, wherein the vehicle door shield has an inwardly oriented surface formed from the lofted fiber pad.
