Impact energy dissipation device
First Claim
1. An impact energy dissipation device comprising:
- a plurality of resistive pins, each of which includes an elongate body;
a track assembly having a series of aligned holes provided along said track assembly for accommodating said plurality of resistive pins extending therethrough; and
a shearing member slidably attached to said track assembly, wherein said shearing member includes a shear blade mounted adjacent said track assembly for shearing said resistive pins in a controlled manner so that each said resistive pin is sheared individually in sequence for dissipating the impact energy in case of a collision.

Abstract
An impact energy dissipation device for the prevention of high-speed vehicles and more specifically automotive vehicles, aircraft, helicopters, components and the like from receiving high-speed impact energy directly onto their structures in case of a collision. The device is to isolate high-speed impact energy from the crashworthy structures by breaking down the huge impact energy with many small manageable shear fragments. The device includes a slidable assembly with a series of resistive pins with predetermined shear strength, staggered in two tandem rows to shear in a controlled manner that only one pin is sheared at a time thereof bearing an approximate equivalent of one shear pin load transmission throughout a collision.
