Abstract: A crash box for fastening a bumper beam on a vehicle, for example a passenger car, has a closed cross section. Its perimeter has at least two longitudinal portions (19, 21), and each of them has a concave portion (20) that passes into convex portions (19, 21) at both sides. The smallest distance from the centre (40) of the crash box to the concave portion is less than 12% shorter than the largest distance from this centre to any one of the adjacent convex portions.
Abstract: A bumper beam has a bow-formed outer profile (14), that has a central flange (16) and two webs (15, 18) and is fastened in two crash boxes (12, 13) with its central flange facing away from the crashboxes. The outer profile has a cover (15) so that the bumper beam will have a closed profile. The cover (15) has a central flange (24) and two webs (25, 26). The webs (17, 18) of the outer profile (14) are joined in pairs with the webs (25, 26) of the cover (15), and the web height of the cover at its center is bigger than the web height of the outer profile (14) at its center.
Abstract: A bumper beam (11) is fastened in two crash boxes (12). The top part and bottom part of each crash box form fastening tabs (34,35) against the top and bottom of the bumper beam (11) and each tab is fastened to the bumper beam with more than one bolt (36,37,57 58). A first hole (55) fits a first bolt (57) whereas the other hole/holes (56) permit for the bumper beam to turn a limited amount around said first bolt. Each tab is fastened to the bumper beam with more than one bolt and nut fastener (36,37,57,58). A first hole (55) fits a first bolt (57) whereas the other hole/holes (56) permit for the bumper beam to turn a limited amount around said first bolt. If a crash box is compressed in an off-set crash, the other crash box remains intact.
Abstract: A bumper beam arrangement comprises a bumper beam fastened in two crash boxes (12,13). The crash boxes are vertically higher than the bumper beam, and the bumper beam is fastened vertically off set in the crash boxes. The portions of the crash boxes that are not covered by the bumper beam extend forwards to the front end of the bumper beam profile.
Abstract: A bumper beam for a vehicle in the form of a hat beam is adapted to be mounted with its opening facing outwards from the vehicle. The beam has a web height that varies along the beam. The web height in portions (25, 26) between a central portion (24) and fastening portions (18, 19) on each side of the central portion has a reduce web height as compared with both the central portion and the side portions.
Abstract: Shock absorbing rectangular boxes (16, 17) are mounted between each one of two structural side beams (14, 15) of a vehicle and a bumper beam (11). The boxes are deep drawn from a steel sheet, and their sidewalls have deformation guides (35) so that the boxes are deformable in a controlled manner during a crash of the vehicle.
Abstract: A front bumper beam for a vehicle comprises a hat profile (11,15) with a cover (10) and it has its cover facing forwards. The beam has a central portion (22) with lower profile than its side portions (20,21) and, as distinguished from the side portions, this lower central portion (22) has a reinforcement in the form of a bent edge (23,24) on at least one of the side flanges (14,15) of the hat profile.
Abstract: A vehicle door has a supporting annular frame 12-19 of high strength steel close to the outer panel and the frame is stamped from a plane sheet so that a side impact guard beam (20) is formed in the same stamping operation. Both the annular frame and the side impact guard beam have hat-formed cross section, and reinforcement plates (21, 22) couple together the outer and inner flanges (26, 27) and give the frame a closed cross section at the connections of the side impact guard beam to the annular frame. The outer side flange (26) of the annular frame carries the outer panel of the door, and the other elements of the door are screwed on the frame 12-19 at the interior side of the frame.
Abstract: A bumper beam arrangement comprises a bumper beam fastened in two crash boxes (12,13). The crash boxes are vertically higher than the bumper beam, and the bumper beam is fastened vertically off set in the crash boxes. The portions of the crash boxes that are not covered by the bumper beam extend forwards to the front end of the bumper beam profile.
Abstract: A vehicle door has a supportive frame (10). A waist rail (14) and a side impact guard beam (22) are formed integrally with the supportive frame. The entire frame is made of high strength sheet steel. The door is produced by hot stamping a steel sheet blank into the shape of a supportive door frame that includes an integral waist rail (14) and a side impact guard beam (22), and hardening the shaped door frame while the frame remains in the shaping tools, and fastening an outer panel (31) to the finished door such that the side collision guard beam (22) of the frame will lie close to the outer panel (31).
Abstract: A supporting frame 10 of a door with an integrated side impact guard beam 22 is made of high strength steel. The outer panel 28 of the door will be close to the side impact guard beam. All the interior units of the door, such as lock and window structure 34–37 with window frame 37, are mounted on a beam structure 30. The beam structure is then mounted on the frame 10 so that the window structure will be between the frame 10 and the beam structure 30.
