STRUCTURE FOR REINFORCING PANEL OF CAR BODY

WIPO Patent Application WO/2011/155249

A1

Keyhole type embossings (13) are formed in a backseat underfoot floor panel (8L) in a manner such that the keyhole type embossings (13) protrude in the thickness direction from the lower side (road surface side) to the upper side (vehicle interior side) so as to reinforce the underfoot floor panel (8L). Each of the keyhole type embossings (13) comprises a circular embossing part (11) and an elliptical embossing part (12) having a width smaller than the diameter of the circular embossing part (11). Since the circular embossing part (11) reinforces the underfoot floor panel (8L) equally in all directions passing through the center of the circular embossing part (11), the underfoot floor panel (8L) has a predetermined strength with respect to bending loads in all directions, and there is no directionality in the degree of strength of the underfoot floor panel (8L). The elliptical embossing part (12) extends radially outward from the circumference of the circular embossing part (11) so as to prevent buckling deformation which is likely to occur at the circular bottom surface of the circular embossing part (11) in the thickness direction of the underfoot floor panel (8L).
