Abstract
The protective equipment for the head comprises a breathing mask provided with a harness and connectable to a source of breathing gas, together with a screen (22) for protecting the eyes against smoke, the screen being provided with a peripheral sealing gasket (26) that presses against the face and against the mask. The mask and the screen are distinct and separable. Manually releasable locking means lock the screen to the mask and bear against the mask so as to press the gasket against the face. The equipment is particularly intended for use by aircraft flight crew members.
