摘要

The safety system, in particular, for a motor vehicle comprises at least two material layers (3, 4) located between the bumper cover and the bumper beam (2) and constituted so that they allow the rate and magnitude of penetration of a colliding object to be established. These quantities in turn allow at least the mass and the velocity of the object to be calculated by an analysis unit.
