It may be the airline's internal policy to mandate that seat belts be worn. For example, an airline may state, "It is required that you wear your seatbelt while you are in your seat." Like Air Canada http://www.youtube.com/watch?v=_FVkYF8iNuA
Release your seat-belts and get out! Leave everything!

Quoting KingairTA (Reply 10): once the attendant goes and sits down some goober will recline the seat.
On that note as a mechanic we quite regularly have the flight attendants write a snag saying something along the lines of "Seat 4A won't stay in upright position", and then when we get on board we will walk back to said seat, find it in the reclined position, put it to the upright position, and then heave and reef on the seat for a few minutes solid and find that the seat is functioning perfectly normal, no matter what we try it stays in the upright position just fine. I often wonder if the reason for the snag was the passenger didn't feel like having it upright, and just told the f/a that he/she can't get it to stay upright so it must be broken.
In all fairness, I've seen lots of times where there actually was a problem with the seat (hydrolock was worn out or a jamnut was loose, etc), but my experience has been that when they snag a seat as wont stay upright, well over 50% of the time we find the seat is working just fine...
Anyways, my apologies for being off topic, but I tend to agree that the seatbelt being on or not lights would almost definately be more work, weight and cost that it's worth. On top of that, I'm sure determined passengers would find a way around it before long...
I've noticed sometimes my arm or leg will rest against the button to recline the seat, hence why it returns to the reclined position when it is put back in the upright position. But that has only been my experience.

My experience when I use to do reliability analysis at an airline showed that anything that a passenger can touch will break more often than any other part on an airplane. Seats and Stowbins are two of the largest mechanical causes of delays. Adding a complex seatbelt will be a nightmare. The system would be so unreliable that flight attendants would not trust it and it defeats its purpose. Getting a green light to come on a suite to indicate that it is secure for landing is already complex and prone to failure.
If you have never designed an airplane part before, let the real designers do the work!
