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.
Claims24
A bumper beam for a vehicle, comprising an outer profile (14) with a bow-shaped central flange (16) and two webs (17, 18), and a cover (15) that provides a closed profile, the outer profile being adapted to be fastened with an outer surface of said bow-shaped central flange facing outwards from the vehicle,
- characterised in that
- the cover (15) has a central flange (24) and two webs (25, 26), and the two webs (25, 26) of the cover are coupled in pairs with the two webs (17, 18) of the outer profile (14), the web height of the cover (15) at its center being greater than the web height of the outer profile (14) at its center, the web height of the outer profile (14) increasing continuously sideways from its center, and the web height of the cover (15) decreasing continuously sideways from its center.
