Description

technical field

[0001] The present invention relates to energy absorbing systems, and more particularly, to energy absorbing vehicle bumper systems. Background technique

[0002] The bumper generally extends widthwise across the front and rear of the vehicle and is mounted on a longitudinally extending bar. A desired energy absorbing bumper system minimizes vehicle damage in a manner that manages the impact energy of a collision with a minimum amount of intrusion, while not exceeding the vehicle's pole load limits. An ideal energy absorber achieves high efficiency by quickly bringing the load just below the load limit of the rod and keeping it constant until the impact energy is dissipated.

[0003] US Patent No. 4,762,352 to Kaisha describes an energy absorbing bumper system. According to this patent, a foam-type resin of polypropylene, polyurethane, etc. is positioned between the support beams and the exterior wall panels to form the assembly.
