Abstract

A side impact protection member for motor vehicle doors with a sheet metal strip of a profiled cross section, which has at least one longitudinally extending bead and has material strips joining the bead on both sides. The sheet metal strip has essentially flat ends for fastening to the motor vehicle door, and the height of the bead decreases continuously in the transition area toward the flat ends of the sheet metal strip. The sheet metal strip is formed of a cold-formable, high-strength steel material with a yield point of at least 980 N/mm.sup.2 and a tensile strength of about 1,250 N/mm.sup.2. The bottom of the bead has an essentially semicircular profile, and outer material strips of the sheet metal strip have edge recesses, which extend at least to the bead, directly adjoining the transition area.
