The arrangement (1) has a protection system i.e. shutter, comprising a guiding unit (5) for guiding motorized casements (3, 4) in translation. A motor (6) actuates the casements to be opened or closed. A rack (7) is arranged opposite to the casements. The motor rotationally drives a pinion (8) meshed with the rack. The motor is housed in the thickness of an opening (2) in a wall (M). The motor is arranged between the casements and a window, and is fixed at the level of an edge of the opening or on a support adjacent to the opening. |
