The invention discloses a backwards-folded electric headrest device which comprises a driving fixing part fixedly mounted on a seat backrest framework, a driving jacking mechanism rotatably mounted on the driving fixing part, a headrest mounting seat mounted on the driving fixing part in a hinged mode and a headrest assembly fixedly mounted on the headrest mounting seat. The moving end of the driving jacking mechanism is hinged to the headrest mounting seat, the headrest assembly comprises a headrest rod and a headrest, forward limiting side plates are arranged on the left side and the right side of the driving fixing part, the left end and the right end of the headrest mounting seat are hinged to the limiting side plates, and arc-shaped guide grooves are formed in the limiting side plates around the hinge points. And limiting convex columns inserted into the arc-shaped guide grooves are correspondingly arranged at the left end and the right end of the headrest mounting seat, so that the backward folding angle of the headrest mounting seat is limited, and the device has the advantages that the design thought is novel, the structure is simple and reasonable, time and labor are saved when the jacking mechanism is driven to automatically jack, and the folding and storage effect of the headrest is guaranteed.
本发明公开了一种向后翻折的电动头枕装置,包括固定安装在座椅靠背骨架上的驱动固定件、可旋转安装在驱动固定件上的驱动顶升机构、铰接安装在驱动固定件上的头枕安装座和固定安装在头枕安装座上的头枕组件,所述驱动顶升机构的移动端与头枕安装座铰接,所述头枕组件包括头枕杆和头枕,所述驱动固定件的左右两侧设有朝前的限位边板,所述头枕安装座左右端与限位边板铰接,且限位边板绕着铰接点设有弧形导向槽,所述头枕安装座左右端对应设有插入弧形导向槽的限位凸柱,从而限制头枕安装座向后翻折的角度,具有设计思路新颖、结构精简合理、驱动顶升机构自动顶升省时省力、保证头枕翻折收纳效果等优点。
