Abstract
When a vehicle is rear-ended and a seated user moves rearward in reaction to the rear-end collision, a load movement of a lumbar part of the seated user is sufficiently transmitted from a pressure plate of operating force generating means to an operating force generating mechanism, regardless of an amount of rearward tilting of a seat back. Then, a pressure roller serving as a driven member of the operating force generating mechanism largely deflects and sufficiently pulls inner cables of respective pulling cable devices, thereby smoothly moving both end portions of a headrest frame upward. As a result, the headrest frame is moved upward smoothly and reliably, and a headrest is moved in an upward-forward direction, that is, toward the head of the seated user smoothly and reliably.
