    • A snowshoe (10) having a pivot axle (24) for pitch rotation of the footbed platform (22) relative to the snowshoe frame (12) is supported from the frame in a manner that provides for significant lateral flexing, i.e. pivoting on the roll axis, to accommodate use of snowshoes on side hill terrain. Instead of a relatively rigid support from the snowshoe frame, the footbed platform is supported by left and right tension bands (30) that are connected to the snowshoe frame and to' left and right ends of the transverse pivot rod (24) that provides pitch rotation. Preferably the connection to each end of the pivot rod is with a rotatable spindle (32) over which the tension band engages, such rollers (32) being connected at right angles to the two ends of the pivot rod. A rotation limiter (50) can be included to limit free rotation of the binding (18) in the pitch-direction to a selected arc. The footbed support system can be employed on any type of snowshoe, whether a tubular frame, non-tubular frame or molded composite snowshoe.
    • 具有用于相对于雪橇框架(12)的脚踏平台(22)的俯仰旋转的枢轴(24)的雪橇(10)从框架被支撑,以提供显着的横向弯曲,即在辊上枢转 轴,以适应在山坡地形上使用雪橇。 代替来自雪鞋框架的相对刚性的支撑件,脚踏平台由连接到雪鞋框架的左右张力带(30)支撑,并且横向枢轴杆(24)的左右端提供间距 回转。 优选地,与枢转杆的每个端部的连接具有可旋转的主轴(32),张力带在该可旋转的主轴(32)上接合,这样的滚子(32)与枢转杆的两端成直角连接。 可以包括旋转限制器(50)以限制装订(18)在俯仰方向上的自由旋转到选定的弧。 脚踏支撑系统可用于任何类型的雪鞋,无论是管状框架,非管状框架还是模制复合雪橇。
