The invention provides a headrest adjusting mechanism and a seat, and relates to the technical field of chairs, the headrest adjusting mechanism provided by the invention comprises a mounting frame, a headrest, a driving part and a limiting part; the headrest is movably connected to the mounting frame; a plurality of clamping positions matched with the limiting pieces are arranged on the mounting frame and are arranged at intervals along the moving track of the headrest; the limiting piece is provided with a locking part, the limiting piece is movably connected to the headrest, and the driving piece is in transmission connection with the limiting piece, so that the headrest adjusting mechanism has a locking state and an unlocking state; in the locking state, the limiting piece is matched with any clamping position, and the locking part is matched with the driving piece to limit the movement of the limiting piece; and in the unlocking state, the locking part is separated from the driving piece, and the driving piece drives the limiting piece to act, so that the limiting piece is separated from the clamping position. In the locking state, the driving piece can prevent the limiting piece from loosening, then the situation that the headrest position is loosened due to external collision can be avoided, and the stability of the headrest is improved.
本发明提供了一种头枕调节机构及座椅,涉及座椅技术领域,本发明提供的头枕调节机构,包括:安装架、头枕、驱动件和限位件;头枕活动连接于安装架;安装架上设有多个适配于限位件的卡位,多个卡位沿头枕的活动轨迹间隔设置;限位件设有锁止部,且限位件活动连接于头枕,驱动件与限位件传动连接,以使头枕调节机构具有锁止状态和解锁状态;在锁止状态限位件配合于任一卡位,锁止部配合于驱动件,以限制限位件活动;在解锁状态锁止部脱离驱动件,驱动件带动限位件动作,以使限位件脱离卡位。在锁止状态下驱动件可阻止限位件产生松动,进而可避免外部碰撞引起头枕位置松动,提高了头枕的稳定性。
