Abstract: A protective helmet (1) has an outer shell (2) and an inner shell (3), the outer shell being displaceable relative to the inner shell by means of at last one sliding layer (4) arranged between the the outer shell and the inner shell. In the edge region of the helmet, the outer shell and the inner shell are interconnected by means of members (5), for absorbing energy on displacement of the outer shell on the inner shell. In this way, impact energy from an oblique impact against the helmet can be absorbed during displacement between the outer shell and the inner shell.
