Abstract
A winding shaft drive (A,A,A) is arranged for operating a retractable covering for an architectural opening. The winding shaft drive includes an at least partially hollow winding shaft (); a driving member () for inducing rotation to the winding shaft; and a shaft brake adapted to be operated by the driving member. The shaft brake includes a preassembled module () for accommodation in the at least partially hollow winding shaft () and has first coupling means () on one axial end thereof for transmitting rotative forces and second coupling means () on the same one axial end for transmitting non-rotative stationary forces. The driving member has a driving hub () for removably coupling to the first coupling means () and a stationary connector (A,A) for removably coupling to the second coupling means (). A shaft brake module () and a driving member () are specifically adapted for use in the winding shaft drive.
