Abstract

A vehicle bumper assembly includes a bumper beam extending from a first beam end to a second beam end to present an outer bumper surface and an inner bumper surface disposed in generally spaced relationship to one another. At least one crash box is disposed adjacent one of the first or second beam ends and extends from a first crash box end secured to the inner bumper surface to a second crash box end to define a crash box cavity. A flange plate is secured to the second crash box end and defines an expansion hole. An energy absorption structure is housed within the crash box cavity and increases in cross-sectional profile from a second absorption end nested within the expansion hole to a first absorption end secured to the outer bumper surface for being pushed through and radially deforming the expansion hole during an impact to absorb additional energy.
