Problems solved by technology

[0005] The present invention solves the problems of existing cushioning systems by using a dual stage energy absorbing cushioning system comprising one or more "softer" energy absorbing surfaces projecting forward in the system. a unique geometry while nesting a more posterior "harder" energy absorbing surface that only functions when higher energy impacts are observed

Embodiment Construction

[0019] In the following description and examples, the present invention is described more specifically, and the examples are only exemplary, and various modifications and changes will be apparent to those skilled in the art. As used in this specification and claims, the singular forms "a," "an," and "the" etc. may also include plural referents unless the context clearly dictates otherwise. Furthermore, as used in the specification and claims, the term "comprising" may include the embodiments "consisting of" and "consisting essentially of". Additionally, all ranges disclosed herein are inclusive of endpoints and independently combinable.

[0020] As used herein, approximate expressions can be used to modify any quantitative expression, where the quantitative expression can be altered without altering the basic function to which it relates. Thus, in some cases, a value modified by a term or terms, such as "about" and "approximately," may not be limited to the precise value stat...

Abstract

A motor vehicle bumper that has enhanced energy absorption characteristics and that includes one or more unique geometry configurations that extend ''softer'' energy absorbing surfaces forward in the system while nesting more ''rigid'' energy absorbing surfaces more rearward only to come into effect when higher energy impacts are observed. The dual energy absorption may be achieved using a numberof configurations and / or methods or a combination of several. In one or more embodiments, the wall thickness of the material used in the component or components may be varied, materials having different stiffness properties may be used, and / or geometries of different depth and section stiffness may be alternated across the bumper system.

Description

technical field [0001] The present invention relates to automotive components, and in particular to a motor vehicle bumper capable of absorbing impact energy. Background technique [0002] In the current automotive market, vehicles exported to other parts of the world must be properly designed to meet the different regulatory requirements of various vehicle systems. Therefore, most export vehicles require different buffer systems to meet the special requirements of their export regions. This often requires the same vehicle to have multiple cushioning components so that different cushioning systems can be fitted for specific regional destinations. This requires additional investment in tooling, equipment, labor, assembly space, etc. Because some of the various regional requirements conflict, it has not been possible to design a system that can meet all global requirements with a single buffer system. [0003] Attempts have been made to design existing buffer systems to add...
