Abstract

A device for impeding the motion of a land vehicle is provided including a net having a first and a second end wherein the ends are separated to provide an elongated net arranged for grabbing a motor vehicle. A first braking device and a second braking are provided. The first braking device includes structure for slowing down the motion of the vehicle, and the second braking device includes structure for further slowing down and stopping the motion of the vehicle. The first and second members of the first braking device are shorter in length than the first and second members of the second braking device, such that the first and second braking device function stepwise with the first braking device braking the net first, and the second braking device braking the net second. The net is also formed of warp elements defining a vehicle wheel engaging structure which extends around the wheel of the vehicle when the vehicle runs over the net.

Dependent claims

A device for impeding the motion of a land vehicle, comprising:

a net having a first end and a second end, said ends being separated to provide an elongated net arranged for grabbing a moving vehicle;
first brake means including a first end brake member attached to said net first end and attached to a substantially fixed anchoring point on a first end side of said elongated net and a second end brake member attached to said net first end and attached to a substantially fixed anchoring point on a second end side of said elongated net for braking said net;
and
second brake means including a first end brake member attached to said net first end and attached to said substantially fixed anchoring point on said second end side of said elongated net and a second end brake member attached to said net second end and attached to said substantially fixed anchoring point on said first end side of said elongated net for braking said net, said first brake means includes means for slowing down motion of said vehicle, and said second brake means includes means for further slowing down and stopping motion of said vehicle, said first brake means first end brake member and second end brake member are of a length which is shorter than said second brake means first brake member and second brake member allowing said first and second brake means to function stepwise with said first brake means braking said net first and said second brake means braking said net second.
