Patent ID: 6908141

Claim:
A structural member for a vehicle, comprising: at least one section being formed with a high-tensile steel pipe having a material property of at least 1,400 MPa in tensile strength and at least 5% in elongation, the at least one section having a cross-sectional configuration of a closed section structure, the cross-sectional configuration satisfying the following expression: 0.65≦ b/a≦ 0.75, and 0.014≦ t/L≦ 0.020, wherein: a is a first maximum length of the cross-sectional configuration in a longitudinal direction, b is a second maximum length of the cross-sectional configuration in a direction perpendicular to the longitudinal direction, L is a circumferential length of the cross-sectional configuration, and t is a wall thickness of the steel pipe.
