TH97019B - Metal pipes for body reinforcement and car body reinforcement with such metal pipes. - Google Patents

Abstract

The metal tubes for vehicle body reinforcement and the vehicle body reinforcement materials according to the invention have curved sections extending along the entire longitudinal length or a specific longitudinal length, wherein, when the reinforcing material is composed so that the substantially circumferential portion of the curve is oriented in the direction of the impact force acting on the vehicle body, the ramp load gradient and the total absorbed energy are increased in the event of a vehicle body crash. In particular, the increase in ramp load gradient for the load properties at the beginning of deformation provides excellent crash bearing capacity for the vehicle body reinforcement. Furthermore, the metal tubes and the reinforcing materials according to the invention can meet the current requirements for much higher crash bearing capacity of vehicle bodies with a reduction in vehicle body weight and production cost, and thus the metal tubes and the reinforcing materials can be widely applied for the protection of occupants in vehicles.
