Embodiment Construction

[0023] Referring to Figures 1 and 2, a prior art energy absorber 10 for use in association with a reinforcing beam 12 is shown in cross-section. As shown, the energy absorber includes upper and lower flanges 14 and 16, respectively, which when mounted overlap a portion of the beam. As shown more clearly with reference to FIG. 2 , prior art energy absorbers tend to twist, as opposed to absorbing and dissipating the impact energy resulting from a collision. Of course, this is undesirable and contrary to the energy absorber of the present invention.

[0024] As shown in FIG. 3, the present invention relates to an energy absorbing system 20 comprising an energy absorber 22 positioned between a reinforcement beam 24 and an outer wall panel 26 which, when assembled, forms the bumper. Those of ordinary skill in the art will understand that the reinforcement beams are connected to longitudinally extending frame bars (not shown) and are made of high strength materials such as steel, ...

Abstract

An energy absorbing system (20) for a vehicle includes an eleongated energy absorber (22) including a flanged frame (32, 34) for attachement to a reinforcing beam (24) and a body (44) including a plurality of spaced apart tunable cruch boxes (54) capable of deformation and progressive collapse upon impact for absorbing the energy of impact.

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. [0004] Another foam-type...
