Bullet-proof plating plate for motor vehicle, has internal surface and external surface provided with alternating bulges and recesses, where angle of external surface continuously changes opposite to normal

摘要

The plate (1) has an internal surface (3), and an external surface (2) provided with alternating bulges (5) and recesses (4), where an angle of the external surface continuously changes opposite to a normal. The bulges and the recesses are directly attached to each other, where the bulges and the recesses include curved surfaces, which are sinusoidal shaped over the entire external surface. An independent claim is also included for a method for manufacturing a plate.
