Abstract
The crash barrier of the invention generally comprises a track, a series of telescoping members, one or more tensioners, and a brake system. The series of telescoping members are slidably engaged on the track. The telescoping members can successively nest within each other. The members are provided with side walls that are sufficiently strong to withstand the impact of a vehicle that veers off the road into the crash barrier. The tensioner is formed of an elastic material. The tensioner is connected between one of the telescoping members and one end of the track. When the telescoping members are fully extended, the tensioners are in a substantially relaxed state. When the members telescope together under the impact of a vehicle, the tensioners stretch, thereby absorbing the kinetic energy of the vehicle. The tensioners are retained in the strained position by a one-way brake system. The brake system can be slowly released such that the stored strain energy of the tensioners can be used to substantially restore the telescoping members of the crash barrier to the extended condition.
