The invention discloses a cushion inclination angle and seat backrest synchronous adjusting mechanism. The synchronous adjusting mechanism comprises a cushion and a backrest and further comprises backrest upper connecting plates, a linkage assembly, a cushion adjusting assembly, a pair of angle adjusters and a pair of backrest lower connecting plates. The lower portions of the two sides of a backrest bent pipe are connected to the right backrest upper connecting plate and the left backrest upper connecting plate respectively, the right backrest upper connecting plate and the left backrest upper connecting plate are rotatably connected with the right backrest lower connecting plate and the left backrest lower connecting plate through the right angle adjuster and the left angle adjuster respectively, and the bottoms of the right backrest lower connecting plate and the left backrest lower connecting plate are connected to a cushion frame. The cushion adjusting assembly is connected with a bottom horizontal pipe of the backrest bent pipe through a linkage assembly, and when the backrest overturns backwards, the cushion adjusting assembly is driven by the linkage assembly to be in linkage so that the inclination angle of a seat can be changed. The mechanism is compact in structure and reasonable in layout, a cushion motor is not needed, synchronous adjustment of the inclination angles of the seat backrest and the cushion is achieved through one connecting rod mechanism, one cushion inclination angle adjusting motor is omitted, the weight is reduced, and the cost is reduced.

    本发明公开了一种坐垫倾角与座椅靠背同步调节机构,包括坐垫和靠背,还包括靠背上连接板、联动组件、坐垫调节组件、一对调角器和一对靠背下连接板;靠背弯管的两侧下部分别连接在右、左靠背上连接板上,右、左靠背上连接板分别通过右、左调角器与右、左靠背下连接板可转动的连接在一起,右、左靠背下连接板的底部连接在坐垫框架上,所述坐垫调节组件通过联动组件与所述靠背弯管的底部水平管连接在一起,靠背向后翻转时通过联动组件带动坐垫调节组件联动实现座椅倾角的改变。本发明结构紧凑,布局合理,无需坐垫电机,通过一套连杆机构实现座椅靠背和坐垫倾角同步调节,节省一个坐垫倾角调节电机,减轻重量,降低成本。
