    • A self-leveling apparatus, a tray table for use with a seat comprising such an apparatus, and a method of maintaining a horizontal level of a mounting member are provided. The self-leveling apparatus comprises: a gear train rotatable about a fixed reference point, the gear train comprising a first gear fixedly mounted to the reference point; a rotatable last gear; and an odd number of rotatable intermediate gears meshing between the first gear and the last gear; and a mounting member adapted to be coupled the last gear, the mounting member having a surface capable of being positioned horizontally; wherein the last gear is further adapted to rotate locally about its axis an equal and opposite amount to a system rotation by the gear train about the reference point, thereby maintaining the surface horizontal.
    • 提供了一种自流平装置,包括这种装置的座椅用托盘,以及保持安装构件的水平面的方法。 所述自动调平装置包括:可围绕固定参考点旋转的齿轮系,所述齿轮系包括固定地安装到所述参考点的第一齿轮; 可旋转的最后一档; 以及在第一齿轮和最后齿轮之间啮合的奇数个可旋转中间齿轮; 以及适于联接最后齿轮的安装构件,所述安装构件具有能够水平定位的表面; 其中最后一个齿轮进一步适于围绕其轴线以齿轮系围绕参考点的系统旋转相等和相反的量旋转,从而将表面保持水平。
