zipper solution on a lid

[otrebor81]

Hello, everyone! !
I write for help
I have to insert a zipper (or similar solution) to open a lid.
the problem is that the zipper must be internal and with a non-optimal fulcrum
yellow is the fixed part
while the other two components are solid: a sheet (where the zipper will be anchored) and a plastic, too weak for the hinge
plastic has to be external and this forces me to decentralize the hinge.
from outside (top) the system must be hidden
Thank you very much

according to the opening you want, with encumbrances, angles and thicknesses available, c he here are not clear, go to the catalog willow and you will find the solution.
otherwise you do a more exhausting sketch and we will give you other solutions.

for an opening of 90-100 degrees, you can use the attached scheme.
ps. you can not use the same dash for two adjacent pieces in section, they must be distinguished.
