Energy attenuating safety system

1. An energy absorbing system operable to minimize the results of a collision between a vehicle traveling on a roadway and a hazard comprising:

the energy absorbing system having a first end and a second end;

the second end of the energy absorbing system disposed adjacent to the hazard with the first end extending therefrom;

a sled slidably disposed proximate the first end of the energy absorbing system;

at least one energy absorbing assembly disposed between the hazard and the sled assembly;

each energy absorbing assembly having at least one energy absorbing element;

each energy absorbing element having a plurality of openings formed therein with respective segments disposed between adjacent openings;

each shredder having a blunt surface generally aligned with the openings formed in the at least one energy absorbing element;

the sled assembly having a first end facing oncoming traffic whereby a collision of a vehicle with the first end of the sled assembly will cause the shredder to slide longitudinally relative to each energy absorbing element and dissipate energy from the vehicle by shredding the segments disposed between respective openings; and

each energy absorbing assembly is installed with each shredder disposed generally vertical relative to the roadway.

2. The energy absorbing system of claim 1 further comprising:

a pair of energy absorbing assemblies extending generally parallel with each other and spaced laterally from each other; and

each shredder including a bolt having a generally blunt, round surface aligned with the openings and segments of the at least one energy absorbing element.

3. The energy absorbing assembly of claim 1 further comprising:

a first row of energy absorbing assemblies and a second row of energy absorbing assemblies extending longitudinally from the hazard;

the first row and the second row of energy absorbing assemblies spaced laterally from each other; and

one of the shredders aligned with energy absorbing elements of the first row of the energy absorbing assemblies and another of the shredders aligned with energy absorbing elements of the second row of the energy absorbing assemblies.

4. The energy absorbing system of claim 1 further comprising:

a first row of energy absorbing assemblies having a first guide rail attached thereto;

a second row of energy absorbing assemblies having a second guide rail attached thereto;

the first guide rail and the second guide rail spaced laterally from each other;

the sled assembly having a first guide assembly slidably disposed on the first guide rail; and

a second guide assembly slidably disposed on the second guide rail.

5. The energy absorbing assembly of claim 1 further comprising:

a pair of energy absorbing assemblies spaced laterally from each other;

the sled assembly slidably coupled with each energy absorbing assembly; and

the shredder disposed adjacent to the respective energy absorbing assemblies whereby a collision between a vehicle and the sled assembly results in each shredder shredding portions of the respective energy absorbing element of each energy absorbing assembly to dissipate energy from the vehicle.

6. The energy absorbing system of claim 1 wherein energy absorbing assembly further comprises:

a pair of supporting beams disposed longitudinally parallel with each other;

at least one energy absorbing element attached to each pair of supporting beams; and

the supporting beams spaced laterally from each other to allow the respective shredder to engage the at least one energy absorbing element to dissipate energy from the vehicle.

7. The energy absorbing system of claim 6 further comprising each supporting beam having a generally C-shaped cross section.

8. The energy absorbing system of claim 6 further comprising each supporting beam having a generally L-shaped cross section.

9. The energy absorbing system of claim 1 further comprising:

each shredder securely attached to the sled assembly;

the sled assembly slidably coupled proximate one end of each energy absorbing assembly; and

the space between the openings and dimensions of the associated segments varying along the length of each energy absorbing element whereby varying amounts of force may be required to move each shredder through the associated energy absorbing element.

10. An energy absorbing system operable to minimize the effects of an impact between a vehicle traveling on a roadway and a hazard comprising:

the energy absorbing system having a first end and a second end;

the second end of the energy absorbing system disposed adjacent to the hazard with the first end spaced therefrom;

a sled slidably disposed on the first end of the energy absorbing system;

at least one energy absorbing assembly disposed between the hazard and the sled assembly;

each energy absorbing assembly having at least one energy absorbing element;

each energy absorbing element have a generally elongated, rectangular configuration with a plurality of openings formed therein and respective lands disposed between adjacent openings;

each energy absorbing element disposed generally horizontal relative to the sled;

the sled having at least one shredder attached thereto and generally aligned with the openings in each energy absorbing element;

the sled having a first end facing oncoming traffic whereby an impact by a vehicle with the first end of the sled will cause the shredder to slide longitudinally relative to each energy absorbing element and dissipate kinetic energy of the vehicle by shredding the lands disposed between the associated openings; and

the at least one shredder disposed generally vertical relative to the associated pair of supporting beams.

11. The energy absorbing system of claim 10 further comprising:

a pair of energy absorbing assemblies extending generally longitudinally from the roadside hazard and spaced laterally from each other;

the shredder including a pair of bolts; and

each bolt having a generally blunt, round surface aligned with the lands and associated openings.

12. The energy absorbing assembly of claim 10 further comprising:

a first row and a second row of energy absorbing assemblies extending longitudinally from the hazard;

the first row and the second row of energy absorbing assemblies spaced laterally from each other; and

the sled having a first shredder aligned with energy absorbing elements of the first row of energy absorbing assemblies and a second shredder aligned with energy absorbing elements of the second row of energy absorbing assemblies.

13. The energy absorbing system of claim 12 further comprising the sled assembly having a first guide assembly and a second guide assembly operable for respective engagement with the first row and the second row of energy absorbing assemblies.

14. The energy absorbing assembly of claim 10 further comprising:
