Abstract
A cover for an air-bag includes a laminate having an inner layer of polymer material and an outer layer of polymer material. Each layer defines a line of mechanical weakness, the line of mechanical weakness in the outer layer being laterally displaced by at least 2 millimeters relative to the line of mechanical weakness in the inner layer such that the inner layer do not overlie one another, the lines of mechanical weakness in the outer layer and in the inner layer together defining a door in the cover adapted to open when a predetermined pressure is provided from the air-bag, the lines of mechanical weakness in the outer layer and in the inner layer further being constituted by lines of reduced thickness.
