The invention belongs to the technical field of automobile seats, and particularly relates to an automobile electric seat backrest supporting structure and an installation method thereof.The automobile electric seat backrest supporting structure comprises a backrest frame, and the backrest frame is of an inverted-U-shaped structure; the two supporting frameworks are fixedly mounted at the bottoms of the two ends of the backrest framework respectively; the two bottom supporting frameworks are symmetrically and rotationally connected to the outer side of the bottom of the backrest framework; and the two back-flushing frames are respectively assembled at the bottoms of the two bottom supporting frameworks. Relative rotation of the output end of the motor and the rotating rod after breakage can be limited in time, relative rotation between the back frame and the bottom supporting frame can be stopped in time, it is avoided that passengers are reversely injured when the seat is damaged, meanwhile, when collision occurs, the whole seat can be rapidly away from a steering wheel, the passengers are rapidly away from a collision area, and the safety of the passengers is improved. And the injury degree of passengers in traffic accidents is reduced.

    本发明属于汽车座椅技术领域,具体涉及一种汽车电动座椅靠背支撑结构及其安装方法,包括靠背框架,所述靠背框架采用倒“U”字型结构框架;支撑架构,两个所述支撑架构分别固定安装在所述靠背框架的两端底部;底撑架构,两个所述底撑架构对称转动连接在所述靠背框架的底部外侧;反冲架,两个所述反冲架分别组装在两个所述底撑架构的底部。本发明能够及时限制电机输出端与转杆断裂后的相对转动,及时停止背框架与底撑架构之间的相对转动,避免座椅靠损坏时,反向伤害乘客,同时可在发生撞击时,使整个座椅快速远离方向盘,使乘客快速远离撞击区域,降低乘客在车祸中的受伤程度。
