The invention relates to the technical field of seat adjustment, and in particular relates to a straight tooth type seat inclination adjusting mechanism which comprises a base frame, a cushion frame and a backrest fixing rod. A front end adjusting assembly and a rear end adjusting assembly are arranged between the cushion frame and the base frame, the rear end adjusting assembly comprises supporting connecting rods which are symmetrically arranged and hinged to the tail portion of the base frame, and a rotating shaft is arranged on the base frame. One end of each supporting connecting rod is connected with the backrest fixing rod, the other end of the supporting connecting rod is hinged to a driving connecting rod, and a driving assembly is arranged on the side wall of the cushion frame. When the forward inclination angle of a seat needs to be adjusted, the driving connecting rod is driven by the driving assembly to move through adjustment of the rear end adjusting assembly, namely thedriving connecting rod drives the supporting connecting rods to move; then, the supporting connecting rods are urged to move upwards along the rotating shaft, and the seat is urged to tilt forwards from the back side; the front end adjusting assembly is the same as the rear end, so that the forward inclination angle and the backward inclination angle of the seat can be adjusted, the backrest andthe seat cushion can integrally incline backwards and forwards, and the seat is more suitable for being used by different crowds.

    本发明涉及一种直齿式座椅斜度调节机构,涉及座椅调节的技术领域,包括底座框、坐垫框、靠背固定杆,坐垫框与底座框间设有前端调节组件和后端调节组件,后端调节组件包括对称设置且铰接于底座框尾部的支撑连杆,底座框上设有转轴,支撑连杆一端与靠背固定杆连接,另一端铰接有驱动连杆,坐垫框侧壁设有驱动组件,当需要调节座椅向前倾斜的角度时,通过后端调节组件调节,即通过驱动组件驱动驱动连杆移动,即驱动连杆带动支撑连杆移动,继而促使支撑连杆沿转轴向上移动,促使座椅自背侧向前翘起,前端调节组件与后端相同,因此可调整座椅前倾和后仰的角度,可使靠背与座垫整体向后向前倾斜,更加适应不同人群的使用。
