Abstract

The energy absorber is provided for interposing between a rigid beam and a bumper skin in order to absorb, by compression, the energy of impacts directed in a crumpling direction. The energy absorber comprises a set of ribs each of which extends parallel to the crumpling direction and each of which possesses a free edge for pressing against the beam. The set of ribs includes at least one rib arranged in the event of an impact so that its free edge remains pressed against the beam, while the rib itself buckles, and at least one other rib arranged in such a manner that in the event of an impact, its free end escapes from the beam, causing the rib to bend.
