Abstract
A headrest movable frame (2) has an upper frame (2b) which is arranged on the upper end face of a seatback and extends in the widthwise direction of the vehicle body, and side frames (10) which are arranged on the side end faces of the seatback and extend in the up-and-down direction. A lower frame (2c) is axially supported on the side frames (10) at a position below the upper frame (2b). Guide holes (3) linearly move a headrest (1) upward and forward by a backward load acting on the lower portion of the lower frame (2c) of the headrest movable frame (2) in a rear impact collision.
