Title:
COLLISION REINFORCEMENT MATERIAL FOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2012/127544
Kind Code:
A1
Abstract:
[Problem] To provide a collision reinforcement material for a vehicle, the collision reinforcement material being configured so that, when a load is inputted therein during a collision of the vehicle, a reduction in the bending rigidity is prevented as much as possible even if the deformation progresses. [Solution] A collision reinforcement material (such as a door impact beam) for a vehicle is provided with a long body section (10). The body section (10) is configured in such a manner that a pair of wall sections (11), a pair of corner curve sections (12), a center flange section (13), and a pair of outer peripheral flange sections (14) are continuously interconnected with each other so that the body section (10) has an open, hat-shaped cross-sectional shape. The body section (10) is divided into three portions (P1, P2, P3). The width (C1) of the center flange section in the portion (P1) is greater than the width (C2) of the center flange section in the portion (P2). The cross-sectional area of the corner curve sections (12) in the portion (P1) is less than the cross-sectional area of the corner curve section in the portion (P2). The cross-sectional height (H1) of the portion (P1) is greater than the cross-sectional height (H2) of the portion (P2). The portion (P3) is provided as a gradually changing portion for smoothly connecting the portion (P1) and the portion (P2).
