Patent 7950724 was granted and assigned to Honda on May, 2011 by the United States Patent and Trademark Office.
A vehicle body rear structure, which includes a rear frame disposed on each side of a vehicle body; and a tank lower frame disposed beneath the rear frame and on the each side of the vehicle body. The rear frame has a load-displacement characteristic having a ratio F/S of load F to displacement S larger than the ratio F/S of the tank lower frame. A cross sectional deformation of the tank lower frame is suppressed so that the load does not rapidly decrease after reaching a maximum of a bending strength.
