A cross member 12 of a passenger vehicle front bumper is supported on a longitudinal frame member 14 by a structurally deformable crash box and a second crash box 26 at least partly behind first crash box 16. Second crash box 26 is supported on frame member 14 on one side and on cross member 12 via a load transfer element 28 capable of transferring impact energy from the cross member 12 to the second crash box 26. Second crash box 26 is preferably coaxially within first crash box 16 and also preferably within frame member 14, and may be located below a shock tower 24. First crash box 16 may be unitary with and form a front portion of frame member 14. Load transfer element 28 is preferably stiffer than first crash box 16. The arrangement reduces the length required to absorb the energy of a frontal impact. |
