The automatic release mechanism when activated in turn activates a control element, wherein at least two locking pawls, preferably arranged at opposite sides of the belt shaft, are caused to interact with locking tooth means to block the belt roller. Means are provided to obtain simultaneous operation of both pawls by a single control element.
