Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 93 words
An energy absorption barrier for rigid road side obstacles to dissipate kinetic energy imparted by a vehicle impact comprises; a ductile metal plate having a hexagon polygon shape, said hexagon polygon shape having two identical pairs of equal length intersecting elements defining oppositely disposed aligned vertexes interconnected by spaced parallel identical intermediate portions therebetween, wherein said metal plate is positioned within said energy absorption barrier so as to be compressed under impact on at least one vertex of said hexagon polygon, and means for mounting said metal plate within said energy absorption barrier.
Claim 2
Dependent Claim 93 words
An energy absorption barrier for rigid road side obstacles to dissipate kinetic energy imparted by a vehicle impact comprises; a ductile metal plate having a hexagon polygon shape, said hexagon polygon shape having two identical pairs of equal length intersecting elements defining oppositely disposed aligned vertexes interconnected by spaced parallel identical intermediate portions therebetween, wherein said metal plate is positioned within said energy absorption barrier so as to be compressed under impact on at least one vertex of said hexagon polygon, and means for mounting said metal plate within said energy absorption barrier.
Claim 3
Dependent Claim 26 words
The energy absorption barrier of claim 1 wherein said metal plate is formed from a pair of identical shaped elements secured together at the respective ends.
Claim 4
Dependent Claim 24 words
The energy absorption barrier of claim 1 wherein said mounting means comprises; bearing flanges secured to said respective free ends of said metal plate.
Claim 5
Dependent Claim 20 words
The energy absorption barrier of claim 1 wherein said metal plate is formed of a milled pack of multiple plates.
Claim 6
Dependent Claim 27 words
The energy absorption barrier of claim 1 wherein a plurality of metal plates are arranged in end to end spaced linear alignment within said energy absorption barrier.
Claim 7
Dependent Claim 12 words
