Abstract:
A headrest which is formed by placing a generally ""M"" shaped headrest frame having a pair of stay portions in a three-dimensional trim cover assembly, then injecting a liquid foaming base material into an inside of the three-dimensional trim cover assembly, and creating a foam padding therein together integrally with the generally ""M"" shaped headrest frame and three-dimensional trim cover assembly, with said pair of stay portions projecting outwardly from the three-dimensional trim cover assembly, said headrest comprising:a cover section of said three-dimensional trim cover assembly which forms one side of said particular trim cover assembly;a pair of through-holes formed in said cover section, through which said pair of stay portions pass, respectively, and project outwardly from said one side of the three-dimensional trim cover assembly;an opening means defined in said one side such as to be disposed between said pair of through-holes said opening means allowing said generally ""M"" shaped headrest frame to be inserted therethrough in to the inside of said three-dimensional trim cover assembly, and further being provided with a bias means for normally causing the opening means to close in a resilient manner; andsaid opening means having a width W.sub.1, W.sub.2 which is smaller relative to a width W between said pair of throughholes, hereby preventing said liquid base foaming material from leaking through the opening means to an outside of said trim cover assembly.
