Kinetic energy dissipation system for dissipating kinetic shock energy
First Claim
1. An energy dissipation system for dissipating kinetic Shock energy including;
- an aluminum tubular member, said tubular member extending longitudnially along an axis from a first end portion to a second end portion, said tubular member having a longitudinal legnth selected at between 5 and 50 cm and a radial diameter of about 4 to 10 cm,at least one hardened cutter/deflector plate disposed adjacent to said first end portion, each cutter/deflector plate including three to five cutting blade members wherein on the occurrence of said shock energy, said cutting blades being movable longitudinally relative to said tubular member towards said second end portion, wherein longitudinal movement of the cutting blades through the tubular member cuts and/or deforms said tubular member to assist in absorbing said kinetic energy.

Abstract
An energy dissipation assembly is provided for mounting between a fixed support and moveable support. The assembly includes a sacrificial deformation tube, a hardened cutter/deflector assembly and, optionally, a connecting cable to maintain the cutter/deflector assembly in juxtaposed coaxial alignment with an end deformation tube. The cutter/deflector assembly has a generally flattened disc shaped profile and includes a central hub, a circular support ring and one or more cutting blades. The support ring is concentrically about the hub and has an inner diameter greater than the outer tube diameter. On the occurrence of a shock force, the cutter/deflector assembly moves axial to cut/deform the deformation tube to dissipate force energy.
