RETRACTABLE ENERGY ABSORBING SYSTEM

摘要

An energy absorbing system includes a supporting member (4), a barrier (2) mechanically connected to the supporting member. The barrier being pivotable between a horizontal position and a predetermined angle. An energy absorber (8) mechanically coupled to the supporting member such that impact energy is absorbed when the barrier is impacted by a vehicle (20), thereby causing the supporting member to travel from a first position to a second position.
