ABSTRACT:
A method for forming a trim cover assembly of a donut-like headrest for use on a vehicle seat. A reversed first cover unit is provided, which has been formed in a reversed state, with its reverse side exposed outwardly, and which is of a generally inverted-U-shaped configuration having a pair of outward openings defined at one side thereof and a pair of inward openings defined inwardly thereof. This reversed first cover unit is turned over into a normal state, with its outer side exposed outwardly. Then, a second cover unit is sewn with such pair of inward openings of said first cover unit, such as to provide an opened side, so that an annular opening is defined by, and along all the foregoing pair of outward openings of said first cover unit and that opened side of said second cover unit. Thereafter, a third cover unit is sewn, at its peripheral end, with and along the thus-defined annular opening of first and second cover units, whereby a donut-like trim cover assembly is produced. In this way, it is easy to accurately sew the cover units together to provide a good constant shape and quality of a resultant trim cover assembly of a donut-like headrest.
