CLAIMS

1. A crash box (10) placed in front and rear bumper areas of vehicles and folding during crash and providing energy damping and occurrence of torsion together with buckling and thus enhancing energy damping characterized by comprising;

• A N area (12) formed in lattice structure between a upper surface (C) and a lower surface (D) of the crash box (10),

• A M area (1 1 ) formed in a manner to have less intensity or more intensity in comparison to the N area (12).

2. The crash box (10) according to claim 1 characterized in that; mentioned M area (1 1 ) is formed from a corner point (A) on the upper surface (C) of the crash box (10) to any one point of a counter edge points (B).

3. The crash box (10) according to claim 1 characterized in that; mentioned M area (1 1 ) is formed from the corner point (A) on the upper surface (C) of the crash box (10) to the corner point (A) on a lower surface (D) in diagonal form.

4. The crash box (10) according to claim 1 characterized by comprising; L areas (13) formed in columns extending to areas outside the crash box (10) and providing intensity differences on the crash box (10) and thus providing exhibit of torsion and buckling action together.

5. The crash box (10) according to claim 1 characterized by comprising; M area (1 1 ), N area (12) and L area (13) consisting of lattice structures or solid structures produced by 3 dimension printer.
