Abstract: The invention relates to a motor vehicle beam shell designed to be placed behind a bumper skin, said shell being provided with a recess for receiving a strength member inside it, the strength member being, for example, a strength member made of metal, in particular of aluminum, or a strength member made of a composite material incorporating a metal. The beam is provided with shell cladding which interfits with the shell, thereby forming a hollow body defining a recess for receiving the strength member.

Abstract: The invention provides a protection piece for protecting a side bodywork part. It possesses both a side wall suitable for covering at least part of the side bodywork part and a flap for extending towards the side bodywork part, the flap being arranged in such a manner as to be capable of retracting so as to allow the wall of said protection piece to move towards the side bodywork part in such a manner that in the event of contact with an obstacle and for forces below a predetermined threshold only the protection piece is deformed, thereby preserving the side bodywork piece. The invention also provides a bodywork assembly and a bodywork part.

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.
