Abstract
The present invention is a vehicle restraining hook. The hook includes a shank extending between an axle interface and a hook bend. The hook bend comprises an inner hook surface extending between the shank and a hook tip. The inner hook surface comprises at least a primary bend and a secondary bend, and in some cases a tertiary bend. Each of the primary bend and secondary bend comprises two planar surfaces, while the tertiary bend comprises a curved surface. These surfaces interact with a RIG bar to generate a force rotating the hook up and ensuring that it maintains contact with the RIG bar.
