A canopy which can be inflated, deployed and retracted by inflation and deflation, respectively. The canopy includes a plurality of beams arranged side by side, an apparatus for supplying the inflatable beams with pressurized fluid, an apparatus for sliding the beams along a rigid beam and at least one orifice made in the wall of the rigid beam placing the apparatus for supplying pressurized-fluid-supply in communication with the inner space of the inflatable beams. The canopy also includes an apparatus for successive positioning of the inner space of each inflatable beam opposite the orifice of the rigid beam to guarantee inflation of the beams by the pressurized fluid from the upper beam to the lower beam and their deflation from the lower beam to the upper beam.
