Vehicle beam assembly with coordinated stiffening members

A rocker insert configured to be disposed along an elongated hollow interior of a vehicle sill structure, the rocker insert comprising:

• a first stiffening member having a top wall, a bottom wall, and a side wall integrally extending between the top wall and the bottom wall, wherein the top wall, the bottom wall, and the side wall together define a channel;
• and
• a second stiffening member disposed at least partially within the channel and comprising a plurality of wall sections that each include an upper wall portion engaged with the top wall and a lower wall portion engaged with the bottom wall at a location spaced along a length of the rocker insert from the upper wall portion,
• wherein the plurality of wall sections of the second stiffening member extend orthogonal to the side wall of the first stiffening member to axially align with an inboard lateral impact force to the vehicle sill structure,
• wherein the plurality of wall sections include angled portions that extend between the upper and lower wall portions and are configured to support the top and bottom walls of the first stiffening member when undergoing the inboard lateral impact force, and
• wherein the side wall of the first stiffening member includes a non-planar formation along the length of the rocker insert, and wherein an outboard edge of the second stiffening member is shaped to conform to the non-planar formation.

A vehicle beam component comprising:

• a first stiffening member having a top wall, a bottom wall disposed parallel to the top wall, and a side wall extending between the top wall and the bottom wall, wherein the top wall, the bottom wall, and the side wall define a channel, wherein the side wall includes a recessed portion that protrudes inward to the channel;
• and
• a second stiffening member disposed at least partially within the channel and comprising a plurality of wall sections that each include an upper wall portion engaged with the top wall and a lower wall portion engaged with the bottom wall at a location spaced along a length of the vehicle beam component from the engagement with the upper wall portion,
• wherein the plurality of wall sections include angled portions that extend between the upper and lower wall portions and are configured to support the top and bottom walls of the first stiffening member when undergoing the inboard lateral impact force, and
• wherein the top and bottom walls of the first stiffening member are configured to be supported by the second stiffening member when undergoing an inboard lateral impact force.
