ABSTRACT:
Collision impact energy-absorbing system for automobiles wherein the front and rear ends of the vehicle are structured into two stages or low and high speed plastic cellular modules such as foam. The impact modules are controlled by a combination of outer plastic skins and bulkheads. The system is designed to maximize the body crush or deceleration distance in order to minimize the "G" loads on the secondary crush zone and passenger compartment during head-on and oblique frontal and rear collisions. The system distributes kinetic energy over as wide an area and as evenly as possible through predetermined transmission paths through the system and into the stronger and heavier parts of the vehicle inner body and chassis structure.
