3d Studio Max - getting an object to follow an object following a path

I understand why this doesn't work - the green box doesn't directly inherit the transforms of the path so it doesn't translate the transforms to the child object (axis stays at origin through the whole path movement), but want to know if there's another way of getting it to work!

This is the basics of how the scene is set up - the large dummy is following a path, and I need the small dummy to link to the large dummy to mimic it. It will be following a spline set up as a windscreen wiper animation.

Are there any better ways of doing this - rigging is not my forte I will admit, but the spline must be used and some kind of path deform will have to be used.

Thanks
