Abstract
An automotive interior trim component is constructed by placing a cast polyvinyl chloride (PVC), vacuum formed or sprayed thermoplastic/thermoset cover stock, or a cloth/fabric outer shell in a closeable mold, spraying a coating of urethane foam forming materials onto a back surface of the shell, closing the mold with a lid so that an insert is held in spaced relation to the shell and clamping the lid shut while the foam forming material react to provide a shaped foam cushion that is between and bonded to the shell and the insert.
