Abstract

A vehicle chassis includes a structural frame having a frame portion that partially defines an open space and that has a predetermined configuration such that the open space maintains a predetermined amount of spatial integrity in the event of a horizontal impact to the vehicle chassis. The frame also includes a frame component operatively connected to the frame portion that further defines the structural frame. The open space provides a protected packaging space wherein certain critical chassis components are placed. The frame portion configuration provides a pre-engineered protected area that may be used in a variety of structural frame configurations. Accordingly, a method for using pre-engineered frame portions is provided.
