Abstract

PURPOSE: A front seat cross member of a vehicle is provided to improve strength and the assembling property, and to reduce parts and process by integrally designing and assembling the front seat cross member with forming a guide tunnel. CONSTITUTION: An upward convex guide tunnel(13) is formed perpendicularly to a tunnel part(12) of a center floor panel(10). A front seat cross member(20) is inserted to the rear part of the center floor panel, and combined by welding. The side of the front seat cross member is opened, and a flange(21) is integrally formed in the lower part of the front seat cross member. The rear part of the center floor panel is assembled with a side seal inner panel(11) by welding. The strength is increased, and the passenger is protected with preventing external force by the front seat cross member and the guide tunnel of the center floor panel at a collision. Torsion or deformation is prevented, and impact is absorbed efficiently.
