Junebug said it: 45 lbs x 10 ” = 450 inch lbs. But they seem to be way too light for the back rest on a chair. I would not think I’d use a metal hinge of that type. It seem pretty small- especially if it would take an impact for someone losing their balance and hitting it hard. The force goes way up in that situation.

If you are going to build these to sell, check the BIFMA ( Business and industry Furniture Manufacturing Assoc) standards. If you had a failure and someone got hurt, that would be what they would be held to in the market place!
I worked in QA for a furniture manufacturer, and we had to test the heck out of products to meet the standards.

A ratcheting support that cannot fall out accidentally would be my choice to meet your needs.

Good luck, Jim
