The invention discloses a safety headrest which comprises a shell, a main support and an auxiliary support, supporting plates are hinged to the two sides of the middle of the front face of the shell, second air bags are connected between the back faces of the supporting plates and the front face of the shell, the auxiliary support is fixed to the inner side of the shell, and a first air bag and a guide mechanism are connected between the auxiliary support and the main support; the first air bag is communicated with the second air bag and provided with an air pipe, and a supporting rod is fixed to the back face of the main support. When the safety headrest is in a normal state, the first air bag and the second air bag are in an uninflated state, when the automobile is collided, the human body leans backwards, the head makes contact with a sensor in the pillowcase on the front face of the shell, and the control system is triggered to control the air path system to inflate the first air bag and the second air bag, under the action of the first air bag, the auxiliary support pops up forwards along the guide mechanism, and meanwhile, the supporting plate rotates along the hinged shaft for buffering under the action of the second air bag, so that safe buffering and damping are achieved, impact resistance is good, and safety is high.

    本发明公开了一种安全头枕,包括外壳、主支撑和辅支撑,所述外壳正面的中部两侧均铰接有支撑板,支撑板的背面与外壳的正面之间连接有第二气囊,所述辅支撑固定于外壳的内侧,辅支撑与主支撑之间连接有第一气囊和导向机构,第一气囊与第二气囊连通且第一气囊上设有气管,所述主支撑的背面固定有支杆。该安全头枕,正常状态时第一气囊和第二气囊处于未充气状态,在汽车发生撞击时,人体后仰,头部接触外壳正面枕套内的传感器,触发控制系统控制气路系统给第一气囊以及第二气囊充气,在第一气囊作用下辅支撑沿导向机构向前弹出、同时第二气囊作用下支撑板沿铰轴转动缓冲,以实现安全缓冲减震,其抗冲击性佳,安全性高。
