<p>A cover for an air-bag installation comprises two superimposed layers of polymer material 3, 4. Each layer carries complementary flanges or fingers 6, the flanges or fingers 6 of the layers 3, 4 being inter-digitated, leaving no air space between the flanges or fingers 6. The base layer 3 is relatively hard and stiff while the outer layer 4 is relatively soft. Both layers 3, 4 can be formed by moulding. <IMAGE></p> |
