Document Type and Number:
Japanese Patent JP4118256
Kind Code:
B2
Abstract:
When a vehicle is rear-ended and a seated user moves rearward in reaction to the rear-end collision, a load generated by a rearward movement of a lumbar part of the seated user is sufficiently transmitted from a pressure plate (10a; 20c) of operating force generating means (10) to an operating force generating mechanism (10B), regardless of an amount of rearward tilting of a seat back (3). Then, a pressure roller (10P) serving as a driven member of the operating force generating mechanism (10B) largely deflects and sufficiently pulls inner cables (11B, 11B) of respective pulling cable devices (11, 11), thereby smoothly moving both end portions of a headrest frame (7) upward. As a result, the headrest frame (7) is moved upward smoothly and reliably, and a headrest (4) is moved in an upward-forward direction, that is, toward the head of the seated user smoothly and reliably.
