<p>A safety helmet includes damping elements for example made from expanded polystyrene added onto a shell made from an elastically deformable material. The whole of the surface, facing the shell, of the damping elements arranged along the periphery of the opening is positioned against the shell to form an inner supporting belt completely in contact with the shell. The helmet is arranged in such a way that a position of the head in the cavity of the helmet causes a deformation of the supporting belt by elastic deformation of the shell according to the morphology of the head, generating permanent tightening of the supporting belt against the head in substantially uniform manner along the supporting belt.</p> |
