    • An example wheel restraint includes a track to be positioned adjacent a vehicle approach path of a loading dock. A shuttle is pivotally coupled to the track via a track follower and pivots between a home position and a deployed position about a shuttle axis substantially parallel to and offset relative to a longitudinal axis of the track. A barrier is pivotally coupled to the shuttle and pivots between a non-blocking position and a blocking position about a pivot axis substantially parallel to and spaced apart from the longitudinal axis of the track such that the shuttle rotates in a first direction about the shuttle axis when the shuttle moves from the home position to the deployed position and bather rotates in a second direction about the pivot axis when the barrier moves from the non-blocking position to the blocking position, where the first direction being different than the second direction.
    • 示例性车轮限制器包括要邻近装载坞的车辆进近路径定位的轨道。 梭子通过轨道跟随器枢转地联接到轨道,并且绕原始位置和展开位置之间枢转,绕梭轴线基本上平行于轨道的纵向轴线并相对于轨道的纵向轴线偏移。 障碍物枢转地联接到梭子并且枢转在非阻挡位置和围绕基本上平行于轨道的纵向轴线并且与轨道的纵向轴线间隔开的枢转轴线的阻挡位置之间,使得梭子沿着穿梭轴线的第一方向旋转 当梭子从原始位置移动到展开位置时,当屏障从非阻挡位置移动到阻挡位置时,其中第一方向不同于第二方向,并且沐浴者在围绕枢转轴线的第二方向上旋转。
