MEMBER FOR REINFORCING VEHICLE BODY

Title:

MEMBER FOR REINFORCING VEHICLE BODY

Document Type and Number:

WIPO Patent Application WO/2006/093005

Kind Code:

A1

Abstract:

A member for reinforcing a vehicle body capable of absorbing more energy than conventional reinforcement members using straight tubes and 'overall length R-bent tubes' at the time of collision of the vehicle body by applying either of a 'partially R-bent tube', a 'multi-portion R-bent tube' and a 'partially recessed and protruded bent tube' specified in this invention to the member for reinforcing the vehicle body so as to develop excellent impact resistance for reinforcing the vehicle body. The dimensions (outer diameter, wall thickness) of a metal tube used as the member for reinforcing the vehicle body are reduced while maintaining the impact resistance and the shape thereof is reviewed to reduce the weight and cost of the vehicle body. Also, since the member can cope with a requested level for a more and more increasing impact resistance of the vehicle body, it can be widely used as an occupant protective technology.
