Definitions

• the invention relates to a shutter installation in a building opening, such as a window or door, surmounted by a lintel comprising an open reservation towards the interior of the building for the installation, from the inside, of a roller shutter mounted on a winding shaft supported in the vicinity of each end by a cheek fixed in the upper part of a window frame.
