Abstract: The general field of the invention is that of the devices for connecting an electronic module in a rack comprising an opening of dimensions close to those of the front face of the module and a seat for fixing and connecting said module, said connection device comprising a first and a second male connector mounted on the rear face of the electronic module; and a first and a second female connector mounted on the fixing seat. In the device according to the invention, the second female connector is mounted in a structure comprising mechanical means for self-centring said second female connector within a clearance range greater than the mechanical positioning tolerances and elastic means arranged so as to hold said second female connector in position. These various means are arranged in such a way as to be able to ensure the blind electrical connection of the electronic module in the rack, its front face resting on the opening.

Abstract: The general field of the invention is that of the display systems comprising an optical combiner and a removable sun visor. The optical combiner is a semi-reflecting plate and the sun visor is a thin, thick and tinted plate, the sun visor comprising means for mechanically fastening on the optical combiner. The optical combiner comprises, on a first side, a first mechanical piece and, on a second side opposite to the first side, a second mechanical piece, the optical sun visor comprises, on a first side, a third mechanical piece and, on a second side opposite to the first side, a fourth mechanical piece in the form of a clip, the third mechanical piece being able to be sunk into the first mechanical piece so as to form a hinge, the rotation axis of which is parallel to the first side of the optical combiner, the fourth mechanical piece being able to be clipped into the third mechanical piece so as to lock the sun visor on the combiner.
