Abstract

A generally annular or donut-like headrest for use on an automotive seal is formed by a donut-like trim cover assembly having an opening, a generally "U" shaped headrest frame and a sealing and connecting frame. These parts are integrally joined using a foaming process. The headrest frame is placed in the donut-like trim cover assembly, with two stay portions thereof projecting outwardly from the opening. The sealing and connecting frame has a groove and is connected between the two stay portions. The edge forming the opening fits into the groove, which effectively prevents leakage of a liquid foaming base material through the opening during the foaming process. A location element is provided on the two stay portions for locating the sealing and connecting frame at a predetermined point thereon and correctly relative to the opening of trim cover assembly. This facilitates ease of precise assembling and forming of the headrest before the foaming process.
