Abstract

Improved winder device for safety belts, of the type comprising a counterweight element in the form of a pendulum or heavy ball, acting on the trigger of a ratchet mechanism associated with the winder reel of the fastening band, characterized essentially by the articulated lever of movement the limited angular portion acting on a lateral projection of the blocking trigger is mounted in turn on a support able to rotate around its axis oriented perpendicular to that of the lever, allowing it, which in turn is activated by the weighing component, to act on the trigger whatever the angle formed between the plane of the projecting flange thereof and that of the actuating lever, in the case of heavy ball a second trigger whose angular movement is limited by two fixed lugs, respectively, in an expansion derived from the spool of winding and in a lug integral with the housing of the mechanism, being said trigger by a helical spring having one of its ends fixed thereon and the other in the expansion derived from the spool, which also has a curvilinear appendage of action, in turn, of the second trigger and a slit opening conjugate of a pin solidary of the housing housing of the mechanism.
