Automobile front upper body stablizer

A stabilization assembly for a body structure of a vehicle, the stabilization assembly comprising:

• a cross-rail having:
• a first attachment structure to couple with a right front wheelhouse of the body structure;
• a second attachment structure to couple with a left front wheelhouse of the body structure;
• and
• a first rail member extending between the first attachment structure and the second attachment structure to transfer loads between the right front wheelhouse and the left front wheelhouse;
• and
• a plenum tie-rail having:
• a third attachment structure to couple with the right front wheelhouse;
• a fourth attachment structure to couple with the left front wheelhouse;
• a fifth attachment structure to couple with a plenum panel of the body structure;
• and
• a second rail member extending between the third attachment structure and the fourth attachment structure, via the fifth attachment structure, to transfer loads between the plenum panel, the right front wheelhouse, and the left front wheelhouse.

A method for stabilization in a vehicle body structure, the method comprising:

• coupling a cross-rail with a right front wheelhouse of the body structure at a first coupling location;
• coupling the cross-rail with a left front wheelhouse of the body structure at a second coupling location;
• coupling a plenum tie-rail with the right front wheelhouse of the body structure substantially at a third coupling location;
• coupling the plenum tie-rail with the left front wheelhouse of the body structure substantially at a fourth coupling location;
• and
• coupling the plenum tie-rail with an upper rail of a plenum panel of the body structure,
• such that the cross-rail transfers transient loads between the right front wheelhouse and the left front wheelhouse, and the plenum tie-rail transfers transient loads between the plenum panel, the right front wheelhouse, and the left front wheelhouse,
• wherein the cross-rail is formed from a first structural member, and the plenum tie-rail is formed from a second structural member that is separate from the first structural member.
