摘要:
A motor vehicle bumper with a crossmember (1) in channel form and a front element (2), which is mounted in front of said crossmember and is in channel form, said crossmember and front element together forming a pedestrian protection system, characterized in that, in the assembled state, the front element (2) has a greater overall height (h2) than the crossmember (1), and the rear part (3a, 3b), which faces the crossmember, of the upper and lower wall regions of said front element are inclined from the horizontal towards the crossmember (1).

摘要:
Bumper crossbeam (10, 10′), having a plane of symmetry (Y) and globally oriented in a direction (T) perpendicular to the plane of symmetry (Y), comprising two attachment areas (12a, 12b) symmetrically arranged with respect to the plane of symmetry (Y) and distant from each other by a distance D, said beam being designed to absorb the energy dissipated by a shock generated by a force substantially horizontal and oriented in a direction (L) perpendicular to said direction (T), made from a globally tubular body (11) with a monotonically varying nominal cross-section (Sn) over most of its length between said attachment areas (12a, 12b), except in two weakened areas (15a, 15b), which are symmetrical with respect to the plane of symmetry (Y), which are remote from the said plane of symmetry by a distance of between 0.10*D and 0.40*D, wherein the second moment of area about the axis (Z) perpendicular to the plane (L, T) is lower in the said weakened areas than expected from the nominal cross-section.
