It is advisable to create the bone length towards the direction of the animation. Not that it is

compulsory.

Now we only need to do is create an IKspline and lock the same on the curve.

The abve command has to be done with the base bone selected.

A selection cursor (with dotted line) appearsselect the top bone and then the curve

Depending on the option various control boxes will appear along the curve
