Problems solved by technology

[0002] When some seats are used, the backrest is at a specific angle. When we adjust the position of the lumbar support and headrest to a comfortable angle, when the person sits on the seat and adjusts the angle of the backrest, we find that the position of the backrest lumbar support will change with the angle of the backrest. The change produces displacement, which causes the position of the lumbar spine of the human body to deviate from the position of the backrest lumbar support. The human body needs to make corresponding position adjustments, which affects the comfort of the user. Therefore, we propose a backrest structure that fits the human back and adjusts the angle to solve the above problems. question

Abstract

The present invention discloses a backrest structure fitting back of human body for angle adjustment. The backrest structure comprises a backrest angle adjusting gear and a transmission rod located below the backrest angle adjusting gear, the bottom of the backrest angle adjusting gear is connected with a transmission gear, the side face of the transmission gear is connected with a height adjusting gear, and the transmission gear and the height adjusting gear are integrated. The transmission gear and the height adjusting gear are both fixedly arranged on the transmission rod in a sleeving mode, a bearing connecting base is arranged on one side of the backrest angle adjusting gear, and the bearing connecting base, the backrest angle adjusting gear and the transmission rod are rotationally installed. The backrest angle adjusting device is reasonable in design, the problem that when the backrest angle of the seat is adjusted, the position of a back curve deviates from the position of a seat curve is solved; therefore, users do not need to adjust the sitting posture, the comfort degree of the seat in the using process is improved, the using requirement is met and application is facilitated.
