摘要： A headrest device includes: a front-rear movement mechanism that moves a moving member in a seat front-rear direction with respect to a base member supported at an upper end portion of a seatback; a head support section that is coupled to the moving member so as to be capable of rotating about an axis running in a seat left-right direction, and that includes a front face configuring a support face to support a head of a seated occupant; and an angle changing mechanism that includes a link member spanning between the head support section and the base member, the link member being rotated with respect to the base member about an axis running in the seat left-right direction by the movement of the moving member so as to rotate the head support section with respect to the moving member about an axis running in the seat left-right direction.

摘要： A headrest includes: a main frame, left and right side frames, and left and right rotation-coupling portions. The main frame is supported at an upper end portion of a seatback. The left and right side frames that are disposed on left and right sides of the main frame. The left and right rotation-coupling portions couple the left and right side frames to the main frame such that the left and right side frames are capable of rotating with respect to the main frame about left and right up-down-extending axes. Each rotation-coupling portion includes a boss hole, a boss, a hinge hole, and a hinge.
