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.
Claims12
Protective helmet in which, between an outer shell (2) and an inner shell (3) arranged inside the latter, there is a sliding layer (4) for making possible displacement of the outer shell relative to the inner shell in the event of an oblique impact against the protective helmet, the protective helmet having connecting members (5), which interconnect the outer shell and the inner shell, characterized in that the outer shell (2) is of the hard type and is harder in the radial direction of the helmet than the inner shell (3), in that the connecting member (5) comprise of an energy absorbing connecting member (5) which is deformable, whereby impact energy is absorbed during displacement between the outer shell and the inner shell.
