Roberto-
I used a load rated continuous plastic hinge (both sources are in links, sources of supply):

It can also be purchased by the foot at McMaster-Carr:
Load-Rated Plastic Piano Hinges Click on an item first and then on the link to its Technical Drawing.
These load-rated polyolefin hinges provide smooth operation and long life both indoors and out. An alternative to metal piano hinges, they are designed to be surface mounted with screws, nails, or other fasteners (not included). They have a flexible webbed middle that's 7/32" Wd. x 3/64" Thick., and can be cut to length with a hacksaw or shears. From the folded position, the range of motion is 360° . Temperature range is -40° to +180° F.
