Abstract

A door reinforcement beam for use in passenger vehicles capable of absorbing lateral impacts includes: a base tube made of a metal having a high degree of strength, toughness and capacity for deformation work and a reinforcing section being disposed and attached to the central portion of the base tube so as to further enhance the door reinforcement's capacity to absorb impact energy.
