Vehicle front rail

Abstract

A front rail configured to be supported by a vehicle frame includes a tubular body formed by a roll-formed high-strength metal and configured to undergo axial loading during a frontal vehicle impact. The high-strength metal steel defines a cross-sectional shape along a length of the tubular body. The tubular body includes a central wall extending from a first side wall to a second side wall defining at least a first longitudinal hollow channel and a second longitudinal hollow channel. A first crush initiator is disposed in the first side wall of the tubular body at a first crush area and is formed in the high-strength metal before roll-forming the tubular body. A second crush initiator is disposed in the corners of the tubular body at a second crush area and is formed in the high-strength metal after roll-forming the tubular body.
