Abstract
A mechanism () comprising a driving element () for rotationally driving a winding shaft () for a closing or sun-protection installation of an opening () and at least one spring () for compensating a weight of the installation. The spring () is mounted around the driving element () and is jointly associated with a sub-unit (), which can be at least partially introduced in a unitary manner inside the shaft (). The spring () includes a first end () kinematically linked to said driving element () so that the first end () is immobilized in rotation abut an axis of rotation (X-X') of the shaft (), and a second end () kinematically linked to the shaft () when the sub-unit () is placed inside the shaft () so that the second end () rotates about the axis of rotation (X-X′).
