A visor for a helmet is disclosed. The visor includes a first lens member, which includes a first transparent shield configured with a photochromic layer. The photochromic layer is configured to adjust a first transmission state of a first viewing area of the first lens member based on the transmission of ambient light through the first viewing area. The visor also includes a second lens member that includes an electrochromic layer. The electrochromic layer is configured to adjust the transmission of ambient light through a second viewing area upon an application of a voltage to the electrochromic layer. The visor also includes a controller configured to adjust a voltage applied to the electrochromic layer, and an attachment element coupled to the first lens member configured to attach to a headgear.

A protective helmet for practicing sports activities or using motorized vehicles is provided. The protective helmet has a cap provided with a front opening at an eye region of a user, and closed by a visor assembly. The visor assembly has at least one at least partially transparent structural lens, a guest-host type liquid crystal (LC) film adapted to modify its own transparency level, arranged behind the at least partially transparent structural lens, at least one electrical source for powering the LC film, and at least one depolarizing layer arranged between the at least partially transparent structural lens and the LC film.

A multifunctional lens assembly includes a functional transparent plate and a layered adhesive body. The functional transparent plate includes spaced apart through holes disposed in an outer peripheral region thereof. Each through hole extends through two opposite surfaces of the outer peripheral region. The layered adhesive body is attached to the functional transparent plate for adhering the functional transparent plate to a face shield of a mobile helmet. The layered adhesive body has a first layer 61 disposed on one of the two opposite surfaces of the outer peripheral region facing toward the face shield, and connection studs respectively extending through the through holes and integrally connecting the first layer.

A shield for a helmet includes a shield having a sun visor rotatably and axially supported at a position different from a rotation center of the shield. The sun visor rotates within a range from a first position where the sun visor, like a bill of a hat, lies above a front opening part and projects forward to a second position where the sun visor lies outside facing the shield in an overlapping manner, and the sun visor is retained in the first position. The sun visor is operated and moved forward and away from the shield to rotate from the first position to the second position.

A protective helmet for practicing sports activities or using motorized vehicles is provided. The protective helmet has a cap provided with a front opening in an eye region of a user and closed by a visor assembly. The visor assembly has at least one at least partially transparent structural lens, the at least partially transparent structural lens being a thermoformed sheet of polymer material, a guest-host type liquid crystal (LC) film adapted to modify its own transparency level, arranged behind the at least partially transparent structural lens, and at least one electrical source for powering the LC film.

The frame follows at least partially a perimeter of the at least partially transparent structural lens.

A glare visor (13) for reducing ambient light intensity perceived by a wearer viewing a head-up display (3) employing display light (7) including a given wavelength(s) of light. The visor includes a visor body comprising optically transparent material which is partially absorbing of light of visible optical wavelengths thereby to reduce the intensity of ambient light transmitted therethrough to the wearer. A transparent optical coating (12) is formed upon a surface of the visor body which is partially transmissive of light of visible optical wavelengths amongst which it is preferentially transmissive of light of a sub-range of wavelengths for including therein the wavelength(s) of display light. This permits a perceived enhancement of contrast between display light (7) relative to ambient light (8).

A helmet including a hard shell defining an exterior surface and an interior volume of space and including a bill. A visor including an engagement structure that is releasably attached to the bill wherein the visor does not pivot relative to the bill when engaged with the bill.
