The invention discloses a backrest frame mechanism which comprises a headrest, a backrest cushion, front cover boards, a rear cover board, a U-shaped frame, a first longitudinal beam and a second longitudinal beam. The front side and the rear side of the U-shaped frame are fixedly connected with the front cover boards and the rear cover board respectively. The backrest cushion is further fixed to the front sides of the front cover boards and sleeved with the U-shaped frame in a penetrating mode. The headrest is arranged at the top of the backrest cushion. The first longitudinal beam and the second longitudinal beam are fixedly arranged at the bottom of the U-shaped frame. By the adoption of the backrest frame mechanism, circular aluminum pipes are bent to form a backrest frame, and the backrest cushion can not be damaged; the headrest is designed to be in an arc shape, the appearance is attractive, and the headrest is better attached to the head and the neck of a passenger; the two sides of the upper end of the backrest cushion protrude, so that the passenger laterally sleeps conveniently.
