ABSTRACT:
In forming a headrest for automotive seat, a three-dimensional trim cover assembly with an opening formed therein is subjected to a foaming process. The trim cover assembly has a pair of extensions formed in that opening and a foldable sealing portion defined in one of those two extensions. The foldable sealing portion is formed with a hole. In operation, both two extensions are turned over via the opening into the trim cover assembly, and during the foaming process, an injection nozzle is inserted through the opening and into the hole of foldable sealing portion. Then, a liquid base foaming material is injected from the injection nozzle into the trim cover assembly and cured therein, during which, the foldable sealing portion is folded about another of the two extension by a pressure applied thereto from the liquid base foaming material being cured, so as to close and seal the opening against leakage of the liquid base foaming material from that particular opening.
