Abstract: A safety helmet is disclosed having a shell and a comfort liner coupled to the inner surface of the shell. The comfort liner is constrained to the front part and to the rear part of the shell, and the helmet has a webbing arranged between the shell and the comfort liner along the upper median portion of the comfort liner. The webbing has a front end constrained to the front part of the comfort liner and a rear end to move the webbing with respect to the shell and cause consequently the change of the overall dimensions of the comfort liner inside the helmet. The webbing is constrained, with respect to the shell, in an operative position corresponding to the overall dimensions of the comfort liner inside the helmet.

Abstract: A device for removably connecting a lining layer to an inner shock-absorbing portion of a helmet, mainly made of foam is disclosed. The device includes a first element constrainable to the lining layer and a second element constrainable to the inner shock-absorbing portion. The second element has a threaded portion that can be inserted by screwing it in the foam of the inner shock-absorbing portion. The device also includes means for the mechanical snap-fit coupling between the first and the second element.

Abstract: Protecting helmet of the type provided with at least one inner shell for shock absorption and at least one outer rigid shell that define a front opening for the face of a user, as well as a protective visor at least rotatable between a lowered position intercepting, at least partially, the front opening and a raised position disengaged from said front opening, and a raising/lowering mechanism to raise/lower the protective visor, wherein the raising/lowering mechanism comprises: at least one base member integral with, or made in a single piece with, or coincident with, part of the outer shell, and arranged in a side position with respect to said front opening; a lever body mounted on said outer shell or said base member so as to rotate around a first axis and provided with a support swinging with respect to said first axis between a proximal position and a distal position with respect to said front opening, said support further comprising hooking means to hook with a corresponding side area of the protectiv

Abstract: A protecting helmet is disclosed having a rigid outer shell, a front opening in the rigid shell for the face of a user, a protective visor rotatable between a lowered position intercepting the front opening and a raised position disengaged from the front opening, and a raising/lowering mechanism of the protective visor. The raising/lowering mechanism has a base member, movably or integrally constrained to, or made in a single piece with, the outer shell and arranged in a side position with respect to the front opening and a fastening pin constrained in a respective opening of the protective visor. The base member has a seat adapted to rotatably and reversibly house the fastening pin and an elastic countering member for the fastening pin. The base member has an unlocking device configured to act on the elastic countering member to release the fastening pin from the seat.

Abstract: A helmet is disclosed having a padding element removably constrained to the shell and provided with a first seat so that a first protrusion integral with the shell is reversibly engaged, reversible male-female coupling members to reversibly couple the shell and the padding element, which are adapted to define a hinge point for the relative rotation between the shell and the padding element. The helmet has restraining members to selectively restrain and release the first protrusion in and from the first seat. The restraining members are movable between a first restraint position to restrain the first protrusion in the first seat, so that the relative rotation between the shell and the padding element is prevented. A second disengagement position of the first protrusion from the first seat is also provided so that the relative rotation between the shell and the padding element is allowed.

Abstract: Disclosed is a device for fastening and adjusting a strap having a base body structured to allow insertion of part of the strap therein, and one ratchet constrained in a rotatable manner to the base body and provided with a coupling portion adapted to engage one corresponding portion of the strap. The device includes first elastic means interposed between the ratchet and the base body to reversibly retain the ratchet in one position of engagement with the strap, and one operating lever to rotate the ratchet from a position of engagement with the strap to a position of disengagement therefrom. The operating lever of the device is constrained on the ratchet in a rotatable manner for one given angular interval. The device also has second elastic means to regulate rotation of the operating lever relative to the ratchet in the angular interval of rotation.

Abstract: Disclosed is a safety helmet having an outer shell, having a front opening, coupled with an inner shell made of shock absorption material, an anti-dazzle visor constrained to the outer shell and movable between a position of engagement and a position of disengagement with the front opening, and an operating portion of the anti-dazzle visor, integral with this latter, and controlled, through a motion transmission cable, by a control slider coupled to a related guide fastened to the outer shell. The control slider is translatable manually between an inactive position and an active position in which the anti-dazzle visor is arranged in a position of engagement. Advantageously, the motion transmission cable has one end integral with the outer she and the other end integral with the control slider, and engages with a drive constrained to the operating portion of the anti-dazzle visor, for movement of this latter.

Abstract: Substantially-linear dipole antenna for safety helmets, of the type comprising two conductive branches arranged to be electrically connected, at one of their ends, to respective radio equipment, the two conductive branches being disposed substantially aligned. The two conductive branches have a length essentially equal to ¼ of the expected operative wavelength of the radio equipment. The dipole antenna further comprises at least two conductive arms, each having a length essentially equal to ½ of said operative wavelength, each of which is electrically connected respectively to the free end of both of the two conductive branches, both having a length essentially equal to ¼ of the operative wavelength.
