Abstract
A crash box for fastening a bumper beam on a vehicle, for example a passenger car, has a closed cross section. Its perimeter has at least two longitudinal portions (19, 21), and each of them has a concave portion (20) that passes into convex portions (19, 21) at both sides. The smallest distance from the centre (40) of the crash box to the concave portion is less than 12% shorter than the largest distance from this centre to any one of the adjacent convex portions.
