According to the multi-angle adjusting device for the automobile seat headrest, when rear-end collision occurs, a driver and passengers are impacted to a backrest by impact force, the pressure receiver can receive an impact signal, if the impact force exceeds an early warning value of the pressure receiver, the signal can be transmitted to the cut-off protector, the cut-off protector can cut off the power of the electromagnet, and the automobile seat headrest is adjusted. At the moment, the telescopic rod moves upwards and pops up, so that the whole headrest assembly ascends, the problem that in the collision state, the upper portion of the head of a driver and passengers is lower than the top end of a headrest, the head moves backwards and upwards, the head crosses the headrest upwards and then swings backwards, and safety accidents are caused is solved, and the problem that the driver and passengers do not adjust the position of the headrest well is also solved; when the telescopic rod moves upwards, the distance between the spring bolt and the fixing piece is increased, the control line is converted into a tightened state from a loose state, the control line is pulled by traction force to open the spring bolt, at the moment, the electric telescopic rod enables the opening and closing headrest and the base to form an acute opening and closing angle, and therefore the heads of drivers and passengers with different figures can be further protected.
本发明提供了一种汽车座椅头枕多角度调节装置,发生追尾时驾乘人员受到冲击力撞向靠背,压力接收器会接收到撞击信号,若撞击力超出压力接收器预警值会将信号传递给切断保护器,切断保护器会将电磁铁断电,此时伸缩杆会向上移动弹出,使头枕组件整体上升,避免了撞击状态下驾乘人员的头部上方低于头枕顶端引发头部向后上方的移动使头部向上越过头枕再向后甩引发安全事故的问题,也避免了驾乘人员没有调整好头枕位置的问题;当伸缩杆上移时锁舌与固定件之间的距离增大,控制线从松弛状态转为紧绷状态,控制线受牵引力拉扯将锁舌打开,此时电动伸缩杆使开合头枕与底座形成一个锐角的开合角度,这样能进一步保护不同身形的驾乘人员的头部。
