RETRACTOR FOR AUTOMOBILE VEHICLE SEAT BELT.

摘要

THE PRESENT INVENTION REFERS TO A WINDER FOR A VEHICLE SAFETY BELT THAT INCLUDES A FRAME (10) IN WHICH A ROLLING COIL IS ENGAGED WITH A BLOCK GEAR (12), AS WELL AS A LOCK TRIGGER (14) PROVIDED WITH AT LEAST ONE LOCKING TOOTH (13). THE LOCK TRIGGER (14) CAN BE MOVED IN THE LOCK GEAR (12) TO PREVENT THE BELT COIL ROTATING IN THE SAFETY BELT WINDING DIRECTION. THE WINDER OF THE INVENTION ALSO INCLUDES A CONTROL RING (22) THAT CAN ROTATE WITH REGARD TO THE BELT COIL AND IS EQUIPPED WITH A COUPLING GEAR (24) THAT IS COUPLED TO THE LOCK TRIGGER (14), A COUPLING TRIGGER (20) ROTATING HOUSING IN THE BELT COIL, A CONTROL PLATE (16) FIXED WITHOUT POSSIBILITY OF TURNING TO THE BELT COIL AND AT WHICH A MASS PLATE IS WHEN POSSIBLE TO BE TURNED WHEN IT ROTATES CONTROL PLATE (16) MAKES COUPLING TRIGGER COUPLING (20) WITH THE COUPLING GEAR (24) OF THE CONTROL RING (22). IN THIS WAY THE TAPE OF THE BELT COIL IN THE WINDING DIRECTION OF THE CONTROL RING (22) IS CARRIED OUT THROUGH THE COUPLING TRIGGER (20), WHILE THE LOCK TRIGGER (14) IS GUIDED TO MAKE A FIRST CONTACT BETWEEN THE LOCKING TOOTH (13) AND THE LOCKING GEAR (12). FROM THIS FIRST CONTACT OF THE LOCK GEAR (12) A TURN TIME IS GENERATED IN THE LOCK TRIGGER (14) SO THAT THIS IS FULLY DISPLACED IN THE LOCK GEAR. THE INVENTION IS CHARACTERIZED BECAUSE THE LOCK TRIGGER (14) AND THE CONTROL RING (22) ARE COUPLED BETWEEN THROUGH A SLIDING GUIDE (32, 34) THAT, AFTER THE FIRST CONTACT BETWEEN THE LOCKING TOOTH (13) AND THE LOCK GEAR (12), TRANSFORMS THE DISPLACEMENT OF THE LOCK TRIGGER (14) INSIDE THE LOCK GEAR (12) IN A ROTATION OF THE CONTROL RING (22) THAT PRECEDS THE ROTATION OF THE BELT COIL IN THE WINDING DIRECTION.
