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 face away from the crash boxes. 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 jointed in pairs with the webs (25, 26) of the cover (15), and the web height of the cover at its centre is bigger than the web height of the outer profile (14) at its centre.
Claims23
A bumper beam for a vehicle, comprising an outer profile (14) with a bow-formed 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 its 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 centre being greater than the web height of the outer profile (14) at its centre, the web height of the outer profile (14) increasing continuously sideways from its centre, and the web height of the cover (15) decreasing continuously sideways from its centre.
