<p>The shutter (1) engages a driving means (2) so as to be displaced along a path between closed and open positions of a bay (3). Detection means (16) enable to be determined if the shutter is subject to a deviation relative to its displacement path, for example following the presence of an obstacle (13) under the shutter. The detection means engages the driving means to cause the stopping or opening of the shutter.</p> |
