Abstract: Embodiments of the present invention provide improved overrunning pulleys that overcome one or more of the deficiencies in the prior art noted above. Embodiments of the present invention provide pulleys that are “springy” in the torque direction, yet have a lower effective spring constant (e.g., are less stiff) over a greater angular range. Further, in at least some embodiments, the inventive pulleys use a low cost and simple torque transfer geometry. Further, in at least some embodiments, the inventive pulleys afford significant overrun. Further, in at least some embodiments, the inventive pulleys are radially small in an overall envelope, in order to allow the alternator to reach its highest possible rotational speed, and thus output, during engine idle. Further, in at least some embodiments, the inventive pulleys are more durable, as they offer the aforementioned dynamics in both directions (torque and counter-torque).

Abstract: A clutch mechanism permits a pulling movement to be transferred or not to the bolt of a lock when turning the internal or external handles attached to separate square-section shafts belonging to clutch elements and which can have independent rotation or they can do so integrally. A first clutch element connected to the outside handle possesses a prismatic projection with a radial orifice into which fits a pulling pin assisted by a spring and which is able to be displaced in order to be introduced into a slot of a second clutch element. The movement is controlled by a motor with a worm-screw linked to a spring which can displace a thruster rocker arm which makes contact with the pulling pin. The mechanism also includes an emergency device having a rod and another spring linked to the thruster rocker arm.
