is this a pull type buckle? or a in seat that doesn't retract. I'd think for the ones that retract at least you could use a switch that measures the size of the "roll" and once it gets low enough assumes the belt is buckled in. + something to see if their sitting in the seat.
I mean you're not worried about wether or not their lieing to you about being buckled in, your worried about safety.
I have a very good solution for passangers in the back seat not wanting to use seat belts.
For my kids "buckle up, or there will be no playing PS3 tonight"... Problem solved...
For all others, especially grown ups... I drive like a maniac if they don't buckle up when I tell them to, so the latteral force throws them back and forth, and some times they have to :puke: when I stop the car.
since my car is like yours i guess thats the right approach!!!!:lol::lol::lol:

If not, you will have to come up with a way to add a sensor to a seatbelt in a way that does not interfere with the safety of their operation that is also child resistant. In most cases, that means taking the seatbelt apart, adding a sensor, putting it back together and being confident that it will still work as reliably as it did before you took it apart.
Are you confident you can do that?
If not, Enforcer's behavior-modification technique will work better. In our car, if you take your seatbelt off, we pull over to the side of the road and nobody goes anywhere until it is on. Simple rule: car in motion, seatbelt on. If there's an issue with that, we move on to reduced privileges for whatever it is that they most want to do this week.
If they are taking their seatbelt off and you aren't aware of it until you arrive at the destination, I suggest the same type of program, only harsher. Kids don't have any concept of the forces involved in a crash.
You could also show them this.
It may be much easier to modify the children's behavior than the seatbelt.
just a friendly bump-- i saw this device on tv recently-- it is actually designed to prevent the car from starting without the seatbelts buckled, but i think that it might be useable in your case with a little rewireing:
Why not just pick up a set of set belt like the ones used on the front seats of you car, if the close enough to the same style you could possible just tie into the factory wires. Then you are just left with finding some sort of weight trigger for the sets. maybe just a switch on the dash to activate the circuit. Sorry i have looked into this before when my little girl went through that phase (I did not do it due to the fact that i am lazy but..) I did look into it for a bit. I have a chevy tahoe older so it was fairly straight forward. Just a thought.
Sorry i missed the post that already went through this. sorry

Cute - I note no price mentioned.
And what a pity it requires batteries!
I wonder - not batteries, no start? Or isn't it quite that vicious?
(I didn't read everything - I stopped when I saw the CR2023 requirement - though they last ~1 year...)
I think a simple optic chopper may be worth a try - albeit mounted initially on the outside - at least for testing.
If there isn't a suitably exposed thin part of the belt "blade" to break the optics (else push the optical-blocker out of the way if normally blocked), maybe magnetic proximity detection - a reed or Hall device. (At least inserting a piece of paper won't defeat that.)
i would say take the buckle apart and fit a microswitch... think twice about how you do it to make sure it will not interfere (too much :-D )
to detect passengers you can go for an infrared beam across the seats (transmitter in one door and the reciever in the other door) or like in a taxi a switch in the seat foam... the last option would be the best since it can detect in what seat the punk that does not like seat belt sits :-D
