Abstract
A tensioning device is provided for selecting and imparting torsional bias to a shaft and simultaneously providing a shock absorbing mechanism, the device including a biasing disposed substantially within the shaft for imparting torsional bias to the shaft, a coupler rotationally fixing one end of the biasing strip to the shaft, and a hub member rotationally fixed to the other end of the biasing strip, the hub member being relatively rotatable with respect to the shaft and including a locking mechanism to lock the hub member to a stationary frame member when the desired torque has been reached.
