A method for forming an armrest, wherein there are provided a three-dimensional box-like trim cover assembly having slit and hole formed therein, a frame and a shaft separate from the frame. In the method, the frame is inserted through the slit into the inside of the trim cover assembly, and then, the shaft is inserted through the hole into the same inside of trim cover assembly, so that the shaft is connected to the frame at a predetermined position within the trim cover assembly via a connecting element. Thereafter, such incomplete armrest unit is subject to foaming in a foaming die, to thereby form a complete armrest. The trim cover assembly includes a high-density foam layer and an impregnation preventive film having plural ventilation holes formed therein in order to prevent impregnation of liquid foaming material into a foam wadding layer of trim cover assembly and attain air permeability of armrest. |
