Abstract: Substructure for a construction that is self-supporting without the substructure and use of the substructure. The invention relates to a substructure for a construction that is self-supporting without the substructure, which construction has at least one carrying component accommodating at least one force, wherein the substructure can be arranged relative to the construction in such a way that it is located at least partly in direct proximity to the at least one carrying component, accommodating at least one force, of the construction. The invention also relates to the use of the substructure as an underpinning structure or as a reinforcement for the construction.

Abstract: A method for producing elastomer skins as lining material for plastic molded articles, such as automobile dashboards, in which a parting agent and a polyurethane system are introduced into a preform (3) taken from a working model (1) forming a manipulable, dimensionally stable elastomer skin (8), which is unmolded after completion of the reaction and finished in a final mold (11) to make a molded article for improving the process of in-mold coating such that UV-resistant elastomer skins are produced easily and absolutely dimensionally accurately, even with undercuts and narrow, deep crevices. A polyurethane paint is provided between the parting agent and the polyurethane system. Prior to the introduction of the polyurethane layer, the preform (3) is at least regionally inverted into a position in which its side facing the spraying tool (2a) is on the outside and has a substantially convex curvature.
