ABSTRACT:
A generally annular or donut-like headrest for use on an automotive seat, which is formed by a donut-like trim cover assembly having an opening, a generally "U" shaped headrest frame and a sealing/connecting frame in an integral manner under 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/connecting frame has a groove and is connected between two stay portions of the headrest frame, such that the edge of that opening is fit engaged in the groove, which effectively prevents leakage of a liquid foaming base material through the opening during the foaming process. Further, a location element is provided on the two stay portions of headrest frame for limiting and locating the sealing/connecting frame at a predetermined point thereon with respect to the opening of trim cover assembly, which facilitates ease of a precise assembling and forming of the headrest under the foaming process.
