Abstract
A vehicle restraint includes a restraining member that rises to an operative position and lowers to a stored position to respectively engage and release an ICC bar of a truck parked at a loading dock. In moving to the lowered stored position, the restraining member also rotates off to its side, so as not to obstruct snow removal equipment or incoming vehicles having an especially low ICC bar or low ground clearance. In some embodiments, rotation of the restraining member is achieved by various actuators that apply a generally uniform torque. A resilient member, moves the restraining member upward to engage the ICC bar, and allows for vertical movement of the truck as it is being loaded or unloaded. Opposing the upward urging of the resilient member, a drive unit forcibly moves the restraining member downward when the truck is ready to be released.
