Abstract:
1. A long vehicular metal absorber comprising a center flange, a top web and a bottom web connected to the two sides of the center flange, a top flange connected to the top web, and a bottom flange connected to the bottom web and formed overall into a hat shaped cross-section, said vehicular metal absorber characterized in that in the hat-shaped cross-section, plane of said top flange and plane of said bottom flange fall on a same flange plane, an internal angle α 1 formed by the top web with said flange plane and an internal angle α 2 formed by the bottom web with said flange plane are respectively over 0 degree to less than 90 degrees, and a bent part is provided in the middle of one or both of the top web and bottom web, an internal angle β 1 formed by the bent part of the top web with the flange plane is over 0 degree to less than α 1 degrees, and an internal angle β 2 formed by the bent part of the bottom web with the flange plane is over 0 degree to less than α 2 degrees, wherein one or both of the top web and bottom web are provided with a recessed or projecting bead substantially parallel to a front-back direction of a vehicle and wherein the metal absorber is made of a steel sheet having a tensile strength (MPa) and sheet thickness (mm) which fall on a line obtained by successively connecting points A TS (0.2,1200), B TS (0.2,400), C TS (0.4,400), D TS (0.4,200), E TS (1.6,200), F TS (1.6,400), G TS (1.4,400), H TS (1.4,600), I TS (1.2,600), J TS (1.2,800), K TS (1.0,800), L TS (1.0,1000), M TS (0.6,1000), N TS (0.6,1200), and A TS (0.2,1200) of (x,y) coordinates in an x-y orthogonal coordinate system having the tensile strength as the y-axis and the sheet thickness as the x-axis or within the area encompassed by said line.
