Patent attributes
A side frame assembly for a vehicle includes a rocker structure and an inboard stiffening beam. The rocker structure includes a metal sheet that has longitudinal bends along a length of the rocker structure separating the upper wall, the lower wall, and the inner wall of the rocker structure. The inboard stiffening beam is disposed along an inboard-facing surface of the inner wall of the rocker structure. The inboard stiffening beam includes a second metal sheet that is formed to define a tubular shape along a length of the inboard stiffening beam. The tubular shape includes a planar upper wall and/or a planar lower wall, the planar extent of which intersects a portion of the rocker structure, such as the inner wall, to form a lateral load path from the rocker structure to the tubular shape of inboard stiffening beam.
