US Patent 8662803 Wheel restraint system

A wheel restraint system has a restraint body having a lower portion and an upper portion. The upper portion is connected to the lower portion by a pivot point. The upper portion has a clamping portion extending across at least a portion of an upper portion of an outer surface of the wheel to be restrained. The upper portion moves about the pivot point between a release position and a clamping position such that the clamping portion moves toward and away from the outer surface of the wheel to be restrained. An actuator moves the upper portion between the release position and the clamping position. An anchor anchors the lower portion to a surface.
