Patent ID: 7862251

Claim:
A vehicle arresting device comprising a net that, in use, lies on the ground in the path of a vehicle to be arrested with one or more transverse rows of upwardly-directed spikes attached to the net at a leading portion thereof such that when the front tires of a vehicle run over said leading portion one or more said spikes become embedded in each said tire, the net becomes wrapped around the front wheels of the vehicle, and the portion of the net between those wheels of the vehicle is pulled tight under the vehicle, thereby preventing further rotation of those wheels, the loops of said net being oriented with a longer dimension in the fore and aft direction than in the transverse direction of the device when laid on the ground in the path of a vehicle to be arrested, whereby in use any widthwise portion of the net is capable of substantial transverse elongation by loops of said portion being pulled from said orientation to a condition in which they are oriented with a longer dimension in the transverse direction than in the fore and aft direction.
