Abstract:
A headrest comprising:at least one headrest stay; a trim cover assembly of three-dimensional configuration conforming to an outer shape of the headrest; said at least one headrest stay being placed in said trim cover assembly, with a part of the headrest stay passing through a predetermined point in the trim cover assembly and projecting outwardly therefrom; a foam padding provided within said trim cover assembly, said foam padding being formed and filled therein by a foaming process including the step of injecting and curing a liquid foaming material within the trim cover assembly; said trim cover assembly including: at least one first extension which is defined at said predetermined point and folded therefrom in a direction inwardly of the trim cover assembly; at least one second extension which is defined at the predetermined point and folded therefrom in a direction inwardly of the trim cover assembly; said at least one first extension being greater in length than said at least one second extension, thus having a region extending beyond a free end of said at least one second extension; said region of the at least one first extension having a through-opening means defined therein, said through-opening means being so arranged as to allow said headrest stay to pass therethrough while being able to be attached closely about a peripheral surface of the headrest stay; said at least one first extension and said at least one second extension being contacted and fixedly joined with each other, so that a through-opening area is defined therebetween at said predetermined point, wherein one side of said through-opening area is opened outwardly of the trim cover assembly while another side thereof is opened inwardly of the trim cover assembly; said region of the at least one first extension being folded about the free end of said at least one second extension, so that the thus-folded region closes and seals said another side of the through-opening area, with said through-opening means laying thereover, wherein said at least one headrest stay passes through said through-opening area and said through-opening means, such that the through-opening means is closely attached about the peripheral surface of the at least one headrest stay, thereby preventing leakage of said liquid foaming material therethrough.
