The invention relates to a seat leg support angle adjusting device which comprises a support assembly, a gear box assembly arranged on the support assembly, a driving assembly located on the gear box assembly and a lead screw assembly, a worm wheel is rotationally connected to the interior of the gear box assembly, and two threaded cylinders are arranged in the worm wheel; the screw rod assembly is in threaded connection with the interior of the threaded cylinder, the two ends of the screw rod assembly extend out of the gearbox assembly and the support assembly, the threaded cylinder is composed of at least four threaded plates, and the threaded plates are slidably connected with telescopic assemblies located on the worm wheel so as to drive the threaded plates not to be in threaded connection with the screw rod assembly any more; the threaded plates can be rotationally adjusted on the telescopic assembly by taking the axes of the threaded cylinders as centers, and the threaded plates of the two threaded cylinders are opposite in rotation direction, so that the threaded plates cannot be in threaded fit with the lead screw assembly; the device has the advantage of manual and electric switching adjustment.

    本发明涉及一种座椅腿托角度调节装置,包括支架组件、设置于支架组件的齿轮箱组件、位于齿轮箱组件上的驱动组件以及丝杆组件,所述齿轮箱组件的内部转动连接有蜗轮,所述蜗轮内设置有两个螺纹筒,所述丝杆组件螺纹连接在螺纹筒内且两端伸出齿轮箱组件和支架组件,所述螺纹筒由至少四个螺纹板组成,且所述螺纹板滑动连接有位于蜗轮上的伸缩组件,以带动螺纹板不再与丝杆组件螺纹连接,当所述蜗轮不转动时,螺纹板能够于伸缩组件以螺纹筒轴心为中心旋转调节,其中两个螺纹筒的螺纹板旋转方向相反,以使得螺纹板不能与丝杆组件螺纹配合;本发明具有手动和电动切换调节的优点。
