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： A dual-visor assembly in which the inner and outer visors are capable of selective left-handed or right-handed actuation to suit a particular operator or operating condition. The inner-visor actuator comprises a lever arm that extends laterally beyond a side edge of the visor through one of a first pair of slots formed in the visor housing. A pin carrried by the arm is resiliently biased into engagement with a detented surface to lock the inner visor in a desired position. Preformed apertures on the left and right sides of the visor permit the actuator lever to be selectively secured to the desired side. The outer-visor actuator comprises a knob carried by a key that fits into either of a pair of keyholes formed on opposite sides of the outer visor. The knob extends through one of a second pair of slots formed in the visor housing at locations opposite the keyholes and is turned to clamp the visor housing to lock the outer visor at the desired position.

摘要翻译： 双面罩组件，其中内罩和外罩能够选择性地左手或右手致动以适合特定的操作者或操作条件。 内遮阳板致动器包括杠杆臂，其通过形成在面罩壳体中的第一对槽中的一个横向延伸超过遮阳板的侧边缘。 由臂固定的销弹性地偏置成与止动表面接合以将内遮阳板锁定在期望的位置。 护目镜左侧和右侧的预制孔允许致动器杆选择性地固定到所需侧。 外遮阳板致动器包括由钥匙承载的旋钮，所述钥匙配合到形成在外遮阳板的相对侧上的一对键槽中的任一个中。 旋钮延伸穿过形成在面罩壳体中的与键孔相对的位置处的第二对槽中的一个，并转动以夹紧遮阳板外壳以将外遮阳板锁定在期望的位置。
