Claim:
A rear module for fitting to a motor vehicle, the module comprising: a large door for being pivotally mounted about an axis, the large door being delimited in a direction parallel to said axis by two stiffener uprights both presenting a cross-section of maximum thickness, taken perpendicularly to the door, that is equal to a first thickness, the large door having an opening extending as far as said uprights in the direction parallel to said axis; and a small door mounted on the large door to move between an open position uncovering said opening, and a closed position closing said opening, the small door being delimited in the direction parallel to the axis by two stiffener uprights both having a cross-section of maximum thickness, taken perpendicularly to the door, that is equal to a second thickness, the uprights of the small door covering the uprights of the large door when the small door is in the closed position: wherein the uprights of the small door and the uprights of the large door are shaped in such a manner as to engage in pairs one in another when said small door is in the closed position so as to present a maximum thickness taken perpendicularly to the door, that is less than the sum of the first and second thicknesses.
