Abstract: A simplified-fitting modular helmet resistant to aerodynamic stresses. The helmet has a base helmet and module, and includes between these two parts two lateral linking devices and an upper linking device. The linking devices include a finger secured to the module inserted into a socket secured to the base helmet and latchable in the assembled position of the helmet by a device of the quarter of a revolution type. The lateral fingers permit a small lateral clearance between the two parts of the helmet. Such a helmet may find particular application as an aircraft pilot helmet.

Abstract: A retractable holographic combiner, of the type comprising a movable holographic mirror placed before the pilot's eyes and designed for the presenting of light images collimated at infinity, superimposed on the external scene, and coming from a projector positioned upline with respect to the combiner, the holographic mirror being connected to a fixed part of the aircraft by a hinged support that provides for holding it and positioning it, wherein the support of the holographic mirror is constituted by a single lateral connecting arm comprising a first upper hinge connecting said arm by one of its ends to the fixed part of the aircraft and a second lower hinge connecting said arm by its other end to a side of the holographic mirror so as to obtain a complete retraction of the assembly.
