ABSTRACT:
A seat back structure of a vehicle seat with a headrest provided thereon, in which a blow-molded plastic seat back frame is utilized, with an anchor bracket pre-assembled integrally therein. The headrest is supportively secured on that anchor bracket. A connecting element, such as a locking element, is provided between the anchor bracket and a body of vehicle, so that a load applied to the headrest is dispersed through the anchor bracket and connecting element toward the body of vehicle, which does not require any reinforced elements and designs to the seat back frame per se and thus permits the seat back frame to be made light in weight.
