A constant velocity drive mechanism of a rotary-wing aircraft rotor, comprises a torque splitting differential mechanism, comprising a driving disc integral in rotation with a rotor mast and connected to each of two driven discs either side of the driving disc, by a least one connecting pin hinged t
A constant velocity drive mechanism of a rotary-wing aircraft rotor, comprises a torque splitting differential mechanism, comprising a driving disc integral in rotation with a rotor mast and connected to each of two driven discs either side of the driving disc, by a least one connecting pin hinged to each of the discs by one of three ball joint connections. Each of the driven discs is connected to a hub of the rotor by at least one of two driving devices, each of which is also hinged to the hub, so as to drive the hub in rotation about a geometrical axis which can be inclined in all directions about the axis of rotation of the mast.

The seat belt retractor according to claim 1 wherein the spindle has a hole therethrough whereby the end of the wire is anchored therein. 3. The seat belt retractor according to claim 1 wherein the wire is wound around only one pin, whereby under the influence of crash forces above a predetermined value, the wire is wound around the spindle in a spiral formation in the direction of the locking ring. 4. The seat belt retractor according to claim 1 wherein the wire contacts the spindle and the pin, whereby under the influence of crash forces above a predetermined value, only the spindle and the pin influence the bending of the wire. now U.S. Pat.
