Floor panel assembly for motor vehicle, having improved strength against side impact

Abstract

Disclosed is a floor panel assembly which delimits a bottom of a passenger compartment. The floor panel assembly includes a floor panel and a pair of reinforcing members. A pair of side sills each of which has a center pillar, are respectively positioned at both sides of the floor panel, and a reinforcing tunnel part is integrally formed on a center portion of the floor panel so that it protrudes upward and extends in a lengthwise direction of a vehicle body. The pair of reinforcing members respectively extend from side walls of the reinforcing tunnel part to lower ends of the center pillars of the side sills, across the floor panel. Each reinforcing member has a hollow beam-shaped contour. The reinforcing members are fastened with respect to the center pillars due to the fact that they are welded to front seat brackets by the medium of fastening brackets.
