ABSTRACT:
A non-lethal energy absorbing vehicle barrier for decelerating an impacting vehicle includes a first gate member and a second gate member disposed downstream of the first gate member. The first and second gate members are movable from a retracted position in which the first and second gate members are disposed so as not to impede vehicular traffic on a vehicle pathway, to a deployed position in which the first and second gate members are disposed to impede vehicular traffic on the vehicle pathway. The first gate has a height that is lower than a height of the second gate in the deployed position. Both the first and second gate members include at least a pair of deformable energy absorbing members that are deformed in a substantially inboard direction by a deforming member when the first and second gates are deformed from a pre-impact configuration to an impact configuration.
