  • Patent number: 9988005
    Abstract: A bumper beam is roll formed so that it gets a closed cross section with, along the length, constant cross section having at least two closed chambers (15, 16) separated by an essentially horizontal partition wall (14). Each chamber has a side (19), which is turned away from the vehicle, with at least one longitudinal concave portion (20, 21; 22, 23) extending along the entire length and one side (24), which is facing the vehicle, with at least one longitudinal convex portion (25, 26; 27, 28) extending along the entire length. After the roll forming, some portions (32) of the cross section are pressed together vertically or horizontally in order to adapt the deformation properties.

  • Patent number: 9254800
    Abstract: A bumper beam has a U-profile with its top directed toward the vehicle. It has fixedly welded mounting plates (16, 17) in the form of horizontal hat-shaped profiles. The mounting plates are bolted to end plates (19) on the side rails (18) of the vehicle, so that collision stresses are transferred to all four sides (29, 30, 32, 33) of the respective side rail.

  • Patent number: 9205726
    Abstract: A door beam has a double hat profile between its mounting ends (12, 13). The height of the outer sidewalls (14, 15) of the double hat profile decreases from a central part (25) of the beam towards the mounting ends (12, 13). Thus the height ratio between the outer (14, 15) and the inner (18, 19) sidewalls is decreased towards the mounting ends.

  • Patent number: 8789872
    Abstract: A safety beam (11) in a vehicle door comprises an attachment end with a plurality of grooves (22, 23, 24) forming through channels to the underlying structure. The grooves have a height of 1-6 mm and an inner width of 3-7 mm and flat surfaces (18-21) between the grooves and to the outside of the outermost grooves have a width of 15-30 mm. Each of the flat surfaces comprises only one spot weld (26-29) to the underlying structure (12). The safety beam is immersed in a bath of anti-corrosive paint after assembly and is thus protected against crevice corrosion.

  • Patent number: 8684449
    Abstract: The invention relates to a B-pillar for a vehicle including a main section (20) with a hat-shaped section (21) comprising a central flange (22), two web portions (23, 24) and two side flanges (25, 26). At least the hat-shaped section (21) is press-hardened and has a breaking strength in excess of 1400 MPa and the side flanges (25, 26) of the hat-shaped section (21) have a breaking strength below 1100 MPa along at least part of the length of the side flanges (25, 26). The B-pillar (13) includes a cover plate (40) welded to the side flanges (25, 26) of the hat-shaped section (21) so as to form a closed profile, the cover plate (40) having a breaking strength below 1100 MPa at least in the region in which it bears against the side flanges (25, 26). The side flanges (25, 26) of the hat-shaped section have a breaking strength below 1100 MPa in the region in which the side flanges bear against the cover plate (40).

  • Patent number: 8465088
    Abstract: An A-pillar for a vehicle includes a first part (15) extending as far as the windscreen and supporting the door hinges and a second arcuate part (16) extending up along the windscreen and continuing towards the back in order to serve as a roof beam (19) above the door. This second part consists of two open sections (23, 24) with flanges (25, 26; 27, 28) welded together so as to give the pillar a closed profile. At least one of the sections (23) is press-hardened and has a breaking strength in excess of 1400 MPa and the flanges (25, 26; 27, 28) of the sections have a breaking strength below 1100 MPa in a portion (35) situated above the door.
