The invention discloses a backward-turning headrest mechanism and an automobile seat thereof, and the headrest mechanism further comprises a driving part which electrically drives a headrest part to turn backward; the lifting moving part is used for lifting the headrest part under the driving of the driving part; the guide mechanism is used for guiding backward folding of the lifting moving component and the headrest component and comprises a headrest fixing plate and a guide support, guide support guide grooves are symmetrically formed in the headrest fixing plate, movement of the guide support is limited by the guide support guide grooves, and the bottom of the insertion rod comprises a shaft hole and a guide pin shaft; the shaft hole is connected with the headrest fixing plate, movement of the guide pin shaft is limited by the insertion rod guide hole of the guide support, the guide pin shaft rotates in the guide support guide groove of the guide support with the shaft hole as the axis, and folding of the headrest component is achieved. Whole-course electric control is achieved, the interference risk of the rear-row seats is eliminated, and the trouble that a passenger needs to install a conventional seat after disassembling the seat for preventing interference is solved.
本发明公开了一种向后翻折头枕机构及其汽车座椅,头枕运动机构进一步包括:驱动部件,电驱动头枕部件向后翻折;升降移动部件,在驱动部件的驱动下对头枕部件进行升降;导向机构,用以对升降移动部件和头枕部件的向后翻折进行导向,导向机构包括头枕固定板和导向支架,头枕固定板上对称开设有导向支架导向槽,导向支架的移动受导向支架导向槽限位,插杆的底部包括轴孔和导向销轴,轴孔与头枕固定板相连,导向销轴的移动受导向支架的插杆导向孔限位,导向销轴以轴孔为轴心,在导向支架的导向支架导向槽内转动,实现头枕部件的翻折。本发明现了全程电动控制,消除了后排座椅干涉风险,还解决常规座椅乘客为防止干涉拆掉后还原又需安装的烦恼。
