Automobile bumper beam comprises zone of least resistance which, on collision, allows upper and lower regions of beam to separate and increase beam height

摘要

The bumper beam (3) which is mounted in the front of the vehicle extends along the driving line (L). It comprises a zone of least resistance (Z) for, in the event of collision, increasing its height in a programmed way. This zone allows an upper (12S) and lower (12I) region of the beam to be separated from each other. The upper and lower regions belong to a front input wall (6) in contact with an obstacle. An Independent claim is included for an automobile front unit.
