Embodiment Construction

[0008] Referring to the accompanying drawings, a crew member 1 wears a helmet 2 which is fastened tightly on the head by strapping it. The helmet 2 is equipped with an external visor 3 or the like (eg reflector, windshield). These are designed by standard type. Built-in goggles 4 are installed inside the helmet 2, which are curved so that their impact on the wearer's peripheral vision is minimized. The built-in visor 4 has a soft rubber edge 5 ensuring a peripheral seal between the wearer's forehead and the vertical edge of the visor 4 . There is no perimeter seal at the bottom of the visor 4 . The built-in goggles 4 are installed and positioned by being installed on the helmet 2 . A soft, standard-type oronasal mask 6 is worn in the usual manner, but does not seal well between it and the section of the built-in goggle 4 that passes through the bridge of the nose or other areas.
