The backrest adjustment principle of the seat recliner is as follows: when the angle of the backrest of the car seat is in the limit position before the recliner, the backrest can be directly pushed to the first gear locking position in the driving mechanism, and the backrest is locked at this time, and the handle is locked (the backrest has a folding function); Adjust the handle to unlock the recliner, push the backrest back to reach the ideal angle and release the handle, and the recliner locks itself; The adjustment handle unlocks the recliner and the backrest automatically returns forward. The schematic diagram of car seat adjustment is shown in the figure below, the angle adjustment stroke of the recliner is 104 °, of which the step-adjusted adjustment is 12 °, and the stepless adjustment (idle stroke) is 92 °.
The structure of the seat adjuster with a rotating handle is shown in the figure below. The seat adjustment diagram is shown in the figure below. The seat adjustment principle is as follows: rotate the handle, drive the handle wheel (eccentric wheel 5) to rotate, and the eccentric rotation of the handle wheel drives the turnover wheel (tooth ring 6) to do the turnover motion, because the internal teeth of the turnover wheel and the stop plate 3 (connected with the seat cushion) and the adjusting arm (connected with the backrest) are meshed at the same time, and the stop plate is fixedly connected with the seat cushion, so that the adjusting arm (that is, the backrest) rotates, and the direction is the same as the direction of rotation of the handle, so that the purpose of adjusting the angle of the backrest is achieved.
