# Manual hook vehicle restraint system

## Abstract

The manual vehicle restraint system utilizes a hook mounted to a main shaft to immobilize a vehicle. The hook and the main shaft rotate around a common axis, biased to rotate by a spring. A latch assembly operably connected to the main shaft may be manually actuated to allow rotation of the main shaft and hook to raise the hook and capture a vehicle. Raising of the hook does not require a power source other than the spring.
