PROBLEM TO BE SOLVED: To provide a headrest adjustment device that enables an electrically-driven positional adjustment for a plurality of kinds of headrests while reducing restrictions by a seat back.SOLUTION: A headrest stay 11 to be fixed to a seat back is provided with: a drive member 50 which is supported while being stored in a headrest; a plurality of position adjustment mechanisms MH, ML and MT which are stored in the headrest and adjust the position of the headrest; and a plurality of position adjustment operating knobs 61H, 61L and 61T arranged individually corresponding to the plurality of position adjustment mechanisms. The driving member 50 is provided with: a rotary motor 57; a plurality of mechanical clutch mechanisms which selectively connect an output shaft to a corresponding position adjustment mechanism to an input shaft which is rotationally driven for the rotary motor 57, accompanying operation of any of the plurality of position adjustment operating knobs 61H, 61L and 61T; and a switch that energizes the rotary motor 57 with a polarity corresponding to an operation direction accompanying the operation of any of the plurality of position adjustment operating knobs 61H, 61L and 61T.SELECTED DRAWING: Figure 2

    【課題】シートバックによる制約を軽減しながらも、電動による複数種類のヘッドレストの位置調整を可能にしたヘッドレスト調整装置を提供する。【解決手段】シートバックに固定されるヘッドレストステー11に、ヘッドレスト内に収容された状態で支持される駆動部材50と、ヘッドレスト内に収容されその位置調整を行う複数の位置調整機構MH,ML,MTと、複数の位置調整機構に対応して個別に配設された複数の位置調整用操作ノブ61H,61L,61Tとを備え、駆動部材50は、回転モータ57と、複数の位置調整用操作ノブ61H,61L,61Tのいずれかの操作に伴い該当する位置調整機構への出力軸と回転モータ57に回転駆動される入力軸とを選択的に接続する複数の機械式のクラッチ機構と、複数の位置調整用操作ノブ61H,61L,61Tのいずれかの操作に伴い操作方向に応じた極性で回転モータ57に通電するスイッチとを備える。【選択図】図2
