[0002] Traditional car headrests mainly adopt a wrapping design, that is, foaming is first performed and then the cover is wrapped. The assembly efficiency is low, and the headrest cover and the headrest body are separated. After long-term use, the headrest cover becomes loose and falls off outside the headrest body, which affects the appearance, comfort, safety and service life of the seat headrest. In order to solve the problems of traditional car headrests, a new car headrest foaming technology has emerged, namely PIP (pour-in-place) foaming technology. This technology specifically involves directly pouring foaming material into the sewn cover to complete the molding in one go. The PIP headrest molded by PIP foaming technology has a relatively high assembly efficiency, does not require additional finishing, and has a full and beautiful appearance that can achieve a relatively unique styling style.
