The invention relates to the field of double-plate combiners for a head-up visor. It is a double-plate combiner for a head-up visor, comprising two substantially flat plates (2, 3), substantially parallel to each other, and held fixedly together by a holding structure (4, 5, 6) which comprises a central baseplate (6), two side flanks (4) connected to the central baseplate (6), two spacers (5) respectively connected to the side flanks (4) and tightly holding the two plates (2, 3) between them, an outer plate (3) being tightly held between the free ends (51) of the spacers (5), an inner plate (2) being tightly held between the ends (52), connected to the side flanks (4), of the spacers (5), the assembly consisting of the plates (2, 3), the side flanks (4) and the spacers (5) having a plane of symmetry substantially orthogonal to the mid-plane of the plates (2, 3), the dimension (l3), from one spacer (5) to the other, of the outer plate (3), being greater than the dimension (l2), from one spacer (5) to the other, of the inner plate (2), and the mid-plane of each spacer (5) being not orthogonal to the mid-plane of the plates (2, 3). The invention can especially be applied to a head-up visor mounted in the cockpit of an aircraft, preferably of the airplane type.
