Abstract
An inflatable roof (1), which can be unfolded and folded away by respectively inflating and deflating it, includes a plurality of longitudinal inflatable beams A, B, C . . . arranged side by side, a mechanism (4) for supplying the inflatable beams with pressurized fluid, and a mechanism for sliding the beams along at least one unfolding or folding-up track (2, 2a) formed by a rigid beam sealingly passing through the inflatable beams. The rigid beam is formed by a pipe (3) for conveying pressurized fluid for inflating or deflating the beams. The pipe communicates at least at one of its ends, with the pressurized-fluid supply mechanism (4), and with the interior of at least one inflatable beam via at least one orifice (5, 5a, 5b . . . ) formed in the wall of the pipe (3). The pipe is equipped with a device or devices for blocking off the at least one orifice.
