ground level 18 may make contact with bollard 2 in a raised position thereby causing bollard 2 flange 14 and sled 4 to travel horizontally from an original position horizontal displacement of sled 4 causes piston 10 to extend from a compressed state to an extended state thereby causing energy absorber 8 to absorb energy such that vehicle 20 decelerates during horizontal displacement flange 14 is guided as hinge 6 travels along flange guide 22 and as sled 4 travels along sled guide 16 fig4 a 4 b and 4 c show perspective views of an energy absorbing bollard system fig4 a shows bollard 2 in lowered original position fig4 b shows bollard 2 in raised original position and fig4 c shows bollard 2 in raised displaced position with sled 4 displaced and piston 10 extended fig5 shows a perspective view of an energy absorbing bollard system according to another aspect of the present disclosure hinge 106 of flange 114 may be connected to hinge 6 of flange 14 by a connector 26 that may transfer force between flange 114 and flange 14 such that the two may travel simultaneously connector 26 may pass through an opening not shown in flange guide 22 in another aspect hinge 106 and flange 114 may connect with one or more of a second flange guide second energy absorber and second sled guide via second sled not shown in another aspect an opening in the ground through which bollard 2 travels from original to displaced position may be covered by disposable sheet of metal plastic or foam insert that breaks away as bollard 2 travels from original to displaced position fig6 shows a side view of an energy.
