  • Energy absorbing impact barrier
    Patent number: 5464177
    Abstract: An energy absorbing motor vehicle barrier includes a collapsible energy absorption assembly which is stored in a vault in the ground. Upon deployment, the energy absorption apparatus is lifted out of its vault, where it thereby expands and deploys. The energy absorption apparatus includes four stages of pairs of elastomeric torsion springs configured into scissors arrangements, with each stage having a progressively higher effective spring rate, to thereby decelerate a vehicle which strikes the apparatus.
