Abstract
A bumper structure for a motor vehicle includes a cross member, and a crash box placed between the cross member and a longitudinal member, with the crash box having an attachment zone. Bolts extend through walls of the attachment zone and the longitudinal member for securing the crash box to the longitudinal member by forcing the attachment zone against the wall of the longitudinal member. The attachment zone undergoes hereby locally an elastic or plastic deformation for realizing a self-centered disposition of the crash box in relation to the longitudinal member. The walls of the attachment zone and the longitudinal member extend at a tolerance distance before the crash box is secured to the longitudinal member.
