Abstract
The present invention is an impact vehicle restraint with spaced shear plates that hold a rotating hook and rotating ramp extension leg. The forward ends of the shear plates support an impact zone structure that forms a ramp plane that accommodates a wide variety of trailer ICC bars. The impact zone structure takes the form of a single central impact plate or dual side impact strips. The central impact plate travels with the hook and spans and rests on the shear plates when the hook is retracted. The dual side impact strips are made of weldable metal with a yield strength of at least 100,000 psi and a Brinell Hardness of at least 300. The central impact plate and hardened strips allow unobstructed rotation of the hook and ramp extension leg. The hook is free to pass through a ramp plane in both embodiments.
