Abstract
A device for the mechanical hooking of a display system to a helmet which includes a sheath that surrounds the body of the display system except for elbowed optical elements leading to the combiner forming the eye-piece of the display system and that has a projecting longitudinal ridge acting as a guiding shaft for the hooking and as a fastening lug, and also includes a hooking stud. The device also has a stage that is interposed between the side wall of the helmet and the sheath. This stage is provided with a channel designed to receive the longitudinal ridge of the sheath and a hook jaw designed to grasp the hooking stud. The device is fixed to the side wall of the helmet by mechanism enabling the adjustment of its position both vertically and laterally, to enable the adjusting of the position of the eye-piece of the display system in the alignment of the helmet wearer's eye.
