The angle adjuster is a load-bearing device installed between the seat back and the seat basin. It mainly realizes the inclination angle and folding motion of the seat back, adapts to the needs of different human postures, and is also a transmission structure for the force acting on the backrest by the human body. The angle adjuster is generally composed of upper and lower connecting plates (some are called AB plates), core parts, connecting rods, handwheels or adjusting handles, return springs and other parts. The core technology of the recliner lies in the parameter design and manufacture of the tooth shape, and there is no program that can be directly imitated in the design of the tooth shape. Because the inner and outer teeth are the main force-bearing parts, there are high requirements on the tooth profile, tooth surface quality (roughness, wear resistance, fatigue strength of the tooth surface), and tooth root strength. The core of the tooth shape design is the smooth meshing of the tooth surface and the high number of contact tooth pairs at any position. The ultimate goal is to improve the transmission efficiency and the maximum tooth shape strength. Therefore, the angle adjuster adopts the precision stamping technology.
