The invention provides a seat-backrest linkage zero-gravity seat adjusting mechanism, and belongs to the technical field of seat adjusting devices. The seat-backrest linkage zero-gravity seat adjusting mechanism comprises: first angle adjuster rotatably connected to two ends of a backrest frame; banana arms, wherein one ends of the banana arms are rotationally connected with the upper plates of the first angle adjusters, and the other ends of the banana arms are fixedly connected with a front transverse pipe located above the front end of the lower edge beam of a seat cushion; a driving device used for driving the front transverse pipe to ascend and descend; and a front Link support and a rear Link support which are sequentially arranged between the two ends of the front transverse pipe and the lower edge beam of the seat cushion. One end of the front Link support is rotationally connected with the front transverse pipe, the other end of the front Link support is rotationally connected with one end of the rear Link support, and the other end of the rear Link support is rotationally connected with the seat cushion lower edge beam through a rotating device. According to the seat-backrest linkage zero-gravity seat adjusting mechanism, a passenger can reach a zero-gravity posture, and the requirement for the strength of driving and driven parts is low.

    本发明提供了一种座靠联动的零重力座椅调节机构,属于座椅调节装置技术领域。该座靠联动的零重力座椅调节机构,包括:第一调角器,其转动连接于靠背骨架的两端;香蕉臂,其一端与第一调角器的上板转动连接,另一端与位于座垫下边梁前端上方的前横管固定连接;驱动装置,其用于驱动前横管进行抬升和下降;前横管的两端与座垫下边梁之间依次设置有前Link支架和后Link支架;前Link支架的一端与前横管转动连接,另一端与后Link支架的一端转动连接,后Link支架的另一端通过旋转装置与座垫下边梁转动连接。本发明提供的座靠联动的零重力座椅调节机构,能够使乘客达到零重力姿态,且对驱动以及被驱动的零件强度要求较低。
