Abstract
A press-formed vehicle structural member includes: a top wall; a pair of lateral walls extending from opposite edges of the top wall in a broadening manner; and a pair of flanges bending outwardly from edges of the lateral walls, wherein the vehicle structural member has a hat-shaped cross section perpendicular to a longitudinal direction of the vehicle structural member. In some embodiments, a bending angle between the lateral walls and the flanges is 87° to 94°. In some embodiments, a length of the flanges from the lateral wall is greater than 11 mm.
