摘要： A foaming die device for forming a headrest is provided, which comprises a lower die having a first protrusion and an upper die having a second protrusion. The lower and upper dies are used for accommodating a trim cover assembly with a headrest stay portion extending outwardly through a stay passage hole formed in the trim cover assembly. The first and second protrusions are adapted to press and turn over a projected area created about the stay passage hole into the inside of that trim cover assembly. Also, a foaming process for forming the headrest, using this foaming die device, is provided, in which the projected area is turned over by the first and second protrusions into the trim cover assembly when placing the trim cover assembly in the dies. Hence, conventional preliminary steps using cylindrical stick to turn over the projected area into the trim cover assembly are eliminated.

摘要： A structure of foaming die for forming a generally inverted-L-shaped headrest, which is designed to receive and enclose an incomplete headrest unit comprising a hollow trim cover assembly of a generally “inverted L” shape having a horizontal upper portion and a vertical head support portion, and at least one headrest stay extending vertically from the horizontal upper portion. This die structure includes die surface portions workable for receiving and enclosing a whole of the hollow trim cover assembly. A movable die element is movably provided so as to be movable toward and away from an operative position where the movable die element is normally set to receive a back cover surface region of such head support portion, thereby allowing the movable die element to be moved away from the operative position and thus allowing a resulting headrest to be removed from the die subsequent to a foaming process.

摘要： An improved vehicle headrest includes a bead between a plastic sleeve and a cloth facing. The cloth is bonded to the plastic sleeve such that an exposed face of the cloth is quickly and reliably connected to the plastic sleeve. The plastic sleeve is then filled with a foam and a positioning post. The inventive headrest is formed by initially placing the cloth material on positioning structure in an anvil. The plastic sleeve has been previously rotationally molded, and is slid onto the anvil and over the cloth material. A dielectric bar is then brought into contact with the plastic sleeve, and a bead is formed. As the bead is formed, a cutting blade cuts the plastic material inwardly of the bead. The cut portion of the sleeve is removed exposing the cloth material. A "RF" compatible barrier layer is formed on a rear face of the cloth material and prevents foam from reaching the exposed forward face.

摘要： A method of molding a headrest of automotive seat comprises the following steps. First, a bag shaped flexible outer skin member is prepared, has an elongate slit formed therethrough. A part of a stay member is inserted into the outer skin member through the slit and set relative to the outer skin member. A given biasing force is applied to longitudinal ends of the slit so that the slit is stretched in longitudinally opposed directions and thus caused to take a closed position. Then, an injection nozzle of a foamable material feeder is put into the slit by expanding the slit against the biasing force. A foamable material is poured into the outer skin member, and the material feeding is stopped when a given amount of material is fed to the outer skin member. The application of the biasing force to the slit is continued until the material is sufficiently cured.
