Abstract
A bumper crossbeam comprises a beam profile and a closing plate. The beam profile extends in its longitudinal axis in the vehicle transverse direction (y direction) and is open in the travel direction (x direction). The beam profile comprises an upper leg, a lower leg and a web connecting the legs, and thus providing a chamber. The closing plate is attached to the upper and lower legs. At least one reinforcing element or a reinforcing element assembly comprising such a reinforcing element is installed in the profile chamber, wherein the reinforcing element comprises, on each of its ends facing in the profile longitudinal direction, a leg angled in the direction toward the web of the beam profile and ending with spacing to the web.
Claims18
A bumper crossbeam comprising:
- a beam profile with a longitudinal extension which extends in its longitudinal axis in a vehicle transverse direction (y direction), wherein the beam profile comprises an upper leg, a lower leg, and a web connecting the legs and thus providing a profile chamber with a profile opening open in a travel direction (x direction);
- a closing plate which spans the profile opening in a vertical direction (z direction) and extends over at least a portion of the longitudinal extension of the beam profile, wherein the closing plate is attached to the upper and lower legs of the beam profile;
- and
- at least one reinforcing element installed in the profile chamber, wherein the reinforcing element comprises a long axis extending in the longitudinal extension of the beam profile and a short axis extending in the vertical direction, with the short axis being multiple times shorter than the long axis;
- wherein an upper edge of the reinforcing element facing toward the profile opening is attached to the upper leg of the beam profile, and a lower edge of the reinforcing element facing toward the profile opening is attached to the lower leg of the beam profile;
- wherein the reinforcing element comprises, on each of its ends facing in the profile longitudinal direction, a leg angled in the direction toward the web of the beam profile and ending with spacing to the web.

- wherein the reinforcing element assembly is attached to a side of the closing plate facing toward the profile opening and extends into the profile chamber of the beam profile;
- wherein the reinforcing element comprises, on each of its ends facing in the profile longitudinal direction, a leg angled in the direction toward the web of the beam profile and ending with spacing to the web.
