Abstract

An anti-collision component consisting of a metal hollow profile for automobiles includes a collision side flange, a body side flange, and a web connected to the flanges. The hollow profile has a longitudinal end at which a cross-sectional configuration is deformed by swaging to reduce a dimension between the flanges. The following relations are established:

t W >T W

R CI ≧( t W −T W )

where t W is a wall thickness of the web at the end, T W is a wall thickness of the web at a portion where the cross-sectional configuration is not deformed, and R CI is an inside corner radius of a corner formed of the web and each flange at the portion.

First claim

What is claimed is:

1. An anti-collision component having a unibody construction comprising:
a collision side flange;
a body side flange;
a web connected to the flanges; and
a longitudinal end at which a cross-sectional configuration is deformed,
wherein the following relation is established:
t W >T W

where t W is a wall thickness of the web at the end, and T W is a wall thickness of the web at a portion where the cross-sectional configuration is not deformed, and
wherein the following relation is established:
R CI ≧( t W −T W )

where R CI is an inside corner radius of a corner formed by the web and each flange at the portion where the cross-sectional configuration is not deformed.

2. The anti-collision component according to claim 1 , wherein the web includes a pair of webs parallel to each other and connected to the flanges.

3. The anti-collision component according to claim 2 , wherein the web further includes an intermediate web parallel to the pair of webs in the cross section thereof, and
wherein the following relation is established:
R I ≧( t I −T I )

where t I is a wall thickness of the intermediate web at the end, T I is a wall thickness of the intermediate web at the portion where the cross-sectional configuration is not deformed, and R I is a fillet radius of each of connecting portions of the intermediate web and each flange at the portion where the cross-sectional configuration is not deformed.

4. The anti-collision component according to claim 1 , wherein the anti-collision component is an aluminum alloy extrusion.

5. The anti-collision component according to claim 1 , wherein the anti-collision component is made by roll forming of a steel plate.
