Being the bumper

摘要

The arched bumper beam on vehicle, the central flange (11), two webs (12 and 13), and the side flange (14 and 15) has the hat form which it possesses. The beam the fixed portion (20 and 21) has in the side section, as for the side flange directing the central flange to outside direction, the fixed area because it locks the beam (30 - 33) forms there. Form height of the beam decreasing continually from the fixed portion facing toward the center, is under 2/3 of the form height whose form height of that beam the fixed portion is highest. The long dent where the central flange rather than in the fixed portion, in that center being widely, extends from the center of the beam facing toward the fixed portion (16) it possesses the stiffener of shape. In the territory between the fixed portion and the fixed portion, the edge which curves (26 and 27) it possesses the side flange, that in connection with the place of start of the edge which curves, the side flange has the dent of cross direction.
