Vehicle frame with offset load path to a hinge pillar and rocker

摘要

A vehicle frame sub-assembly including a hinge pillar assembly and A-pillar assembly. A high strength hinge pillar reinforcement and A-pillar reinforcement are provided to increase the support in roof crush tests. Collision impact loads are transferred through an upper load path, lower load path, upper intermediate load path, and lower intermediate load path. A back-up rail receives loads from the front rail. The back-up rail transfers loads to the rocker and through a back-up rail extension to the hinge pillar assembly. An upper intermediate load path transfers loads from the upper rail through a fork rail to the hinge pillar assembly.
