Abstract

The invention relates to a bumper for motor vehicles comprising an impact absorber which is made of an energy-absorbing foamed material and arranged between the outer covering (3) and an inner girder subject to bending (4). In order to meet the requirements of the pendulum test and the lower leg test, the impact absorber (1) is at least partially provided with burls (2) or recesses (5).
