A vehicle cross member assembly is provided which includes first and second cross members each having first and second ends, and first and second connectors connects to the first ends of the cross member to vehicle structures. The assembly includes a bracket connected to a tunnel structure on a vehicle. The bracket includes first and second brackets for connecting the second ends of the first and second cross members. At least one of the first and second cross members is configured to move laterally inward and downward into the tunnel during a sufficient lateral impact of the vehicle. Additionally, one or more seats may be mounted to the cross members such that the seats move inward and rotate away from the point of impingement during a side impact event.
