Abstract

A door impact beam for a motor vehicle includes a pot-shaped member made from a metal sheet and extending over a major part of a length of the beam to define two legs and a bridge interconnecting the legs. The bridge has a central length portion which is formed with an embossment defined by a depth, with a ratio of the depth of the embossment to a height of the pot-shaped member in midsection ranging between 1:3 and 1:6. The pot-shaped member has side flanges extending transversely from lower longitudinal edges of the legs in the central length portion.
