Move points creating a polyline by parameters created by the polyline itself

Good day!

 

I'm struggling with creating a polyline (or lines between points, they don't have to be one line) with are using itself to change it's geometry.

The goal is to, from the points created by dividing a curve, offset them with a static value and then by weaving the original points and the offseted ones create a polyline. The points must be offseted in the direction perpendicular to the polylinesegment created just after the first original point and the second offseted point.

 

Below is my try, here I use the normal from the curve controlling the original points for the offset direction 

Any suggestions?
