Patent ID: 8850622

Claim:
A safety helmet comprising: a cavity open onto the outside through an opening to engage a head of a user in the cavity; an outer shell in a single part, and made from elastically deformable material, having a modulus of elasticity between 1500 and 4500 MPa; a plurality of damping elements added-on to the inside of the shell, wherein the damping elements are formed by a rigid foam, and the damping elements are arranged at the periphery of the opening against the inner surface of the shell to form an inner supporting belt completely in contact with the shell; and joining means to join the damping elements to one another, to allow relative movements between the damping elements, wherein a position of the head of the user in the cavity causes a deformation of the supporting belt by elastic deformation of the shell according to the morphology of the head of the user, generating permanent tightening of the supporting belt against the head of the user in a substantially uniform manner along the supporting belt, wherein the joining means comprises a single structure connecting the set of damping elements to one another, wherein the single structure is in the form of a spider, the head of which is fixed to a top damping element and each leg of which performs joining between the top damping element and a peripheral damping element, and wherein the top and peripheral damping elements are obtained by overmolding on the single structure.
