20080246308 | Vehicle body reinforcing member - Using as a vehicle body reinforcing member any one of a bent tube with a partial bend of radius R, a tube with a plurality of portions that are bent at radius R, and a bent tube with mixed bends of inward and outward projection according to the present invention makes it possible, during a vehicle body collision, to absorb more energy than and exhibit better impact resistance than a vehicle body reinforcing member that uses one of a known straight tube and a curved tube of radius R entirely. Thus the dimensions (outside diameter, wall thickness) of the metal tube that is used as the vehicle body reinforcing member can be reduced, and the tube shape can be modified, while impact resistance is maintained. Modifying the shape in this manner makes it possible to provide the ever higher required level of vehicle body impact resistance at the same time that it reduces the weight of the vehicle body and lowers the cost. The present invention can therefore be widely used as an occupant protection technology. | 10-09-2008 |
