PROFILE FOR A STRUCTURAL BEAM OF A VEHICLE

A profile having two end wing portions (1, 5) having substantially the transversal direction (Y), two lateral wall portions (2, 4) having substantially the height direction (Z), a frontal wall portion (3) having substantially the transversal direction (Y), two curved transition zones (R1, R2) between the lateral wall portions (2, 4) and the frontal wall portion (3), two curved transition zones (R3, R4) between the end wing portions (1, 5) and the lateral wall portions (2, 4), wherein a specific portion (l1, l2) of each curved transition zones (R1, R2) between the lateral wall portions (2, 4) and the frontal wall portion (3) have a tensile strength lower than the tensile strength of the rest of the cross-section. The invention also relates to a longitudinal beam, a cross-member, pillar, B-Pillar or C-Pillar comprising such profile, and to a vehicle provided thereof. 一种异型件，该异型件具有：具有大致横向方向(Y)的两个端翼部分(1、5)；具有大致高度方向(Z)的两个侧壁部分(2、4)；具有大致横向方向(Y)的前壁部分(3)；位于侧壁部分(2、4)与前壁部分(3)之间的两个弯曲过渡区(R1、R2)；位于端翼部分(1、5)与侧壁部分(2、4)之间的两个弯曲
