A tensioning cable actuator has a housing with a nut held in the housing. The nut has threads which engage a lead screw that has corresponding threads. A pulley cradle is fixed to the lead screw. The pulley cradle is disposed within the housing to translate axially with the lead screw upon rotation of the nut. A pulley is disposed in the pulley cradle. A Bowden cable wire wraps around the pulley and is anchored to the housing so that the wire moves into or out of the Bowden cable sleeve twice far as the lead screw moves. |
