The door, comprising a pliable panel (4) with transverse stiffening bars (12) that folds into accordion pleats at the top of slideway channels (2) when operated by an electric motor, has guides (14) that extend from the ends of one or more stiffening bars in a plane offset from the plane of the panel and allowing the panel edge to make contact with the channel surface. The guides are connected to the stiffening bar(s) by couplings that allow the guides to rotate; the couplings are also able to bend or break in the event of an external force greater than a set value being applied to the door. |
