摘要： A dual-visor assembly for use with a helmet such as that of an aircraft crew member in which an inner visor is releasably secured to the helmet by snap fasteners that release toward the rear of the helmet, while an outer visor is releasably secured to the helmet over the inner visor by snap fasteners that release toward the front of the helmet to prevent the inadvertent release of both visors simultaneously. The snap fasteners are carried by straps that are secured to the inner surface of the inner visor and to the outer surface of the outer visor to prevent entanglement. Elements carried by the visors space the inner visor from the outer visor as well as from the surface of the helmet. A soft cover is releasably secured over the outer visor in its raised position to prevent scratching of the outer visor or other structures.

摘要： Described is a kit, an optical insert assembly and a method for attaching an optical insert to a viewing lens of an eye-shielding device. The kit includes an optical insert with an outer perimeter, and a flexible border attachment element with an inner periphery area extending inward of the outer perimeter of the optical insert, and an outer periphery area extending outward of the outer perimeter of the optical insert, and having a first adhesive area for attachment to the optical insert and a second adhesive area for attachment to the viewing lens. When attached, the border attachment element defines a buffer zone spanning the inner periphery and outer periphery areas. The optical insert assembly includes the elements of the kits described herein, attached to a viewing lens of an eye-shielding device.

摘要： The invention relates to an optical filter comprising: at least one optically transparent liquid-crystal shutter, the shutter having a polarization voltage ULCD that marks a threshold between two polarization states, and being designed to switch between at least two opacities OP1 and OP2, OP2 being strictly higher than OP1, when it receives a voltage that is above or below, respectively, the polarization voltage ULCD; and an electronic system comprising: an electronic module for controlling the liquid-crystal shutter, designed to control the voltage applied to the liquid crystal shutter; a photosensitive sensor, designed to deliver, to the electronic control module, a continuous voltage Ucs that varies depending on the luminous intensity that it receives, the photosensitive sensor being the only power supply of the electronic control module and the liquid-crystal shutter, the optical filter being characterized in that, if the photosensitive sensor receives a luminous intensity below a dazzle threshold le, the liquid-crystal shutter has an opacity OP1, and in that the electronic control module is designed, when the photosensitive sensor receives a luminous intensity above the dazzle threshold le, to deliver, to the liquid-crystal shutter, a continuous voltage Ue that is strictly above the polarization voltage ULCD of the shutter, so that the latter switches from opacity OP1 to opacity OP2.
