ABSTRACT:
A vehicle restraint is provided for securing a parked vehicle against a loading dock during loading or unloading of the vehicle. The restraint includes a carriage member which is mounted on a dock wall for vertical movement and is biased to assume a predetermined elevated rest position relative to the roadway on which the vehicle is parked. The carriage member moves vertically downwardly from the rest position upon an external force of predetermined magnitude being exerted on an exposed cam surface of the carriage member. An attaching member is adjustably mounted on the carriage member for movement relative thereto between a vehicle locking mode and a vehicle release mode. Adjustably mounted on a lower portion of the carriage member is a toe-like member which normally assumes a pendent position projecting from the carriage member. The toe-like member has an exposed surface portion in an aligned coplanar relation with the carriage member cam surface and forms an extension thereof when the toe-like member assumes its pendent position. The toe-like member is moveable from its normal pendent position [by a reactive force exerted thereon by the roadway] when the carriage member moves vertically downwardly beyond a predetermined distance from its rest position.
