The invention discloses a low-sitting-posture multidirectional-adjustment zero-gravity seat framework. The lower end of a first left front connecting rod is hinged to a left sliding rail front support, the upper end of the first left front connecting rod is hinged to a second left front connecting rod, and the other end of the second left front connecting rod is hinged to a front transverse pipe; the lower end of a right front connecting rod is hinged to the right sliding rail front support, and a first toothed plate driving device is arranged between the upper end of the right front connecting rod and the front transverse pipe and can adjust the inclination angle of the seat frame framework through movement of the front transverse pipe. The upper end of the right rear connecting rod is fixedly connected with the rear transverse pipe; a second toothed plate driving device is arranged between the left sliding rail rear support and the side plate on the left side, and the second toothed plate driving device can adjust the height of the seat frame framework through movement of the rear transverse pipe; and a safety belt retractor is arranged below the seat frame skeleton. The inclination angle and the height can be adjusted, zero-gravity adjustment can be achieved through cooperation of the inclination angle and the height, the driving device for inclination angle and height adjustment is small in occupied space, and the requirement for low-sitting-posture seat arrangement can be met.
本发明公开了一种低坐姿的多向调节零重力座椅骨架,左一前连杆的下端与左滑轨前支架铰接,上端与左二前连杆铰接,左二前连杆的另一端与前横管铰接;右前连杆的下端与右滑轨前支架铰接,上端与前横管之间设有第一齿板驱动装置,第一齿板驱动装置能通过前横管的运动调节座框骨架的倾角;右后连杆的下端与右滑轨后支架铰接,上端与后横管固定连接;左滑轨后支架与左侧的侧边板之间设有第二齿板驱动装置,第二齿板驱动装置能通过后横管的运动调节座框骨架的高度;座框骨架的下方设有安全带卷收器。本发明的倾角和高度均可调节,两者配合能实现零重力调节,且倾角和高度调节的驱动装置占用空间小,能满足低坐姿的座椅布置。
