ABSTRACT:
A process for manufacturing a padded element using a mold having an upper mold and a lower mold. The process includes placing a cushion member on the lower mold. The upper surface of the cushion member includes a first portion having an open recess with a boundary extending therearound for containing a liquid foamable polymeric composition in the recess. A trim cover with a finished upper surface is placed in contact with the interior surface of the upper mold. A liquid foamable polymeric composition is dispensed in the open recess within the boundary, and the upper mold and the lower mold are closed to cover the open recess and form an enclosure containing the liquid foamable polymeric composition. The polymeric composition expands to fill substantially the enclosure and adheres to the cushion member and to the inner surface of the trim cover.
