Abstract:
This rear-end element (2) for motor vehicle includes a carrier structural element (6) forming an energy-absorbing element after impact, and a carrier structural frame (8). At least the carrier structural element (6) has a cellular structure formed of cells (30, 32) extending longitudinally through the carrier structural element (6) between a back face and a front face of the carrier structural element (6) and opening onto the back and/or front face of the carrier structural element (6). A rear end (44) which includes the rear-end element (2).
Abstract:
This beam (4) is intended to be located between a shield skin (2) and a rear face (6) of a motor vehicle front assembly (1), said beam (4) being designed to deform by absorbing energy in the event of an impact with the shield skin (2), said beam (4) having an approximately planar front face (8). The beam (4) comprises a rear fairing element (10) having a concavity (16) facing the front of the vehicle so as to promote a laminar flow of air from the front face (8) of the beam (4) toward the rear face (6) of the front assembly (1) of the motor vehicle.
Abstract:
This assembly comprises a structural frame (2) and a plastic material bumper (4) formed so as to match the shape of a bumper skin and arranged against the structural frame (2), said bumper (4) comprising an upper cross member (34) and a lower cross member (36) interconnected via vertical connecting beams (38), the upper (34) and lower (36) cross members each having a central portion (48) and two lateral portions (50) arranged on either side of the central portion (48), said cross members (34, 36) comprising a plurality of ribs (52). The number of ribs (52) in the central portion (48) of the upper cross member (34) and/or of the lower cross member (36) is greater than the number of ribs (52) of each lateral portion (50) of the upper cross member (34) and/or of the lower cross member (36).
