ABSTRACT:
An arrangement and method for securing a headrest stay in a seat, wherein a seat back frame with a staty holder is placed in a mold, the stay holder having an aperture formed therein, a core die having a thin portion is inserted in the stay holder, and then a base foamable material is injected in the mold, for carrying out a foaming. The the base material liquid is flowed through the aperture into the stay holder, and as a result of the foaming, there is formed a cushiony part in the stay holder, which acts as a detent for preventing a headrest stay, when inserted in the stay holder, against horizontal and vertical movement or wobbling in the holder.
