Abstract: This bumper assembly is adapted for a motor vehicle having a structure including a pair of upper side members (6) and a pair of lower side members (8). It includes an energy absorbing panel (12) having at least two columns (16) each provided to bear on the ends of an upper side member (6) and a lower side member (8) and a beam (18) extending transversely between the columns (16). According to one embodiment, the bumper assembly includes a plate (36) doubling the beam (18) such that the beam (18) is compressed between a frontal face (36a) of the plate (36) in case of impact. The device is applicable to front or rear bumpers.

Abstract: The assembly is of the type comprising two pairs of front longitudinal members of a chassis of a motor vehicle and support and fixing mounting plates arranged at the front ends of the longitudinal members and comprising a front bumper shield comprising a one-piece plastics material frame consisting of an upper bumper beam and a lower bumper beam and two vertical members connecting the upper and lower bumper beams, the vertical members of the frame being configured to act as impact absorbers and fixed resting directly against the mounting plates.

Abstract: Such a distribution of the ribs 52 makes it possible to determine the behavior of the bumper under impact. In particular, the behavior of the bumper 4 varies depending on the point of impact on said bumper 4 upon collision. The bumper 4 according to the invention makes it possible to satisfy pedestrian impact standards, which are becoming ever more stringent. In particular, in the case of a pedestrian impact, provision must be made for deceleration of the pedestrian's knee, irrespective of the point of impact of the knee.

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).
