ABSTRACT:
An energy absorbing system. The energy absorbing system includes a supporting member, a barrier pivotable between a first angular position and a second angular position, where the barrier becomes mechanically coupled to the supporting member when arranged at a predetermined angular position, and an energy absorber mechanically coupled to the supporting member, where the energy absorber absorbs energy when the supporting member travels from a first position to a second position.
