Curve + Bones in a mesh....

Hi all,
well if you can have a look at my Blender file here Belt-curve-bones.blend (684 KB)…
I have a simple mesh (a straight belt) rigged with bones and a curve. All is working fine except that they are not at the same place…
Help would be appreciated. Is it a problem of origin?

I cant get your file; The page tells me “Invalid Attachment specified” message.

Any way here is good tutorial on spline IK setup:

OK I’ll look at the video.
I also reloaded the Blander file.
Hope it’s fine.
