Image Number 7 for United States Patent #8128310.
A vehicle restraint system is provided, comprised of an easily installable and transportable base having a deployable vehicle retention means contained therein. In particular, a rigid base over which vehicles may drive is provided, having a deployable vehicle retention means, such as a net or flexible panel, disposed in the base. In addition, lockable rollers, deployable plates and tire puncturing devices are disposed in the base, to prevent or resist movement of the vehicle relative to the base. The base is merely laid upon a surface, and requires no mounting thereto. Upon impact with a vehicle, the vehicle is retained on the base, and the forward motion/inertia of the vehicle is depleted via frictional engagement (sliding) of the base over the mounting surface, wherein the base and vehicle come to a controlled stop within a short distance.
