  • Seat back structure of vehicle seat
    Patent number: 7540562
    Abstract: A seat back structure with headrest includes a vertical pressure-receiving element and cross pressure-receiving element. The headrest is fixed on a support rod operatively connected via a rotating link with an actuator link assembly. The vertical pressure-receiving element, upon one load being applied thereto from a seat occupant's lumber part, is displaced backwardly and upwardly via guide hole to push the support rod, thereby causing commencement of rotation of the rotating links to move the headrest upwardly. Thereafter, the cross pressure-receiving element, connected with the actuator link assembly, is displaced backwardly, upon another load being applied thereto from a seat occupant's dorsal part, thereby assisting in continuation of the rotation of rotating link.
