<p>The assembly (10) comprises a motion transmitting core element (12) having first and second ends. A tension adjustment mechanism (18) disposed between the first and second ends of the core element (12) comprises a helical spring (20) responsive to axial forces having a first end and a second end, an inner diameter and an outer diameter and spaced apart helical coils (22). The spring is secured to the core element (12) coaxial with the core element. There is a flange (24) disposed on the core element (12) inside the spring (20), the flange extending radially away from the core element, beyond the inner diameter of the spring (20) and between adjacent coils (22) for moving along the spring (20) upon relative rotation between the spring and the flange.</p> |
