Abstract
A motor-vehicle convertible top has a flexible and waterproof outer layer defining a roof having edges and an inner surface, a pair of sides joined at the edges to the roof, and a rear wall extending between the sides and a rear edge of the roof. A heat- and sound-insulating inner layer of a foamable plastic is bonded directly to the inner surface of the roof and inner surfaces of the sides. A pair of reinforcing bands extending along the edges are fixed to the layers. A plurality of crosswise rigid reinforcing struts extend between the bands and secured to the inner layer. The outer layer has a textile inner surface to which the inner layer is directly bonded. The inner layer is molded in place in a closed mold under 140 bar to 150 bar pressure, so that it is integrally united with the outer layer. The inner layer is polyurethane and has a Shore D hardness of about 40 and a polyol:isocyanate ratio of about 100:38 by weight. Furthermore the inner layer has a thickness of between 2 mm and 6 mm. A roof liner is bonded to mounting strips, which are then attached to the struts.
