Seat Belt Locking Mechanism
Seat Belt Locking Mechanism
(OP)
I am designing a wirelocking(size of wire .125") system using the principle of seat belt locking mechanism in cars. The wire is run in to the pipe at a constant rate when it shears, the wire is lost. Hence the design. I was unable to find a reference of the seat belt mechanism in the net. Which would be the best possible source to find the working principle(with schematics).

The spring is winded inside the belt that help in the winding of the belt.If you try to open the belt be cautious sometime the spring recoils out with great force.
Second thing, you can only pull out the belt from the assembly only if it place in the orientation that it is fixed inside the car.
I had a chance to replace the seat belt inside my car, when I observe these problems. Might be it will help you.

When a wireline is attached to the Fish Neck of a Top Sub, it is simply threaded into a hole, like threading a needle. A set of pawls located in slots then grab the wire. As the wireline tension increases, the pawls grab the wire harder. Thus you have a situation where resistance to slip is proportional to wireline tension.
I have used this mechanism extensively, most recently to grab a wire specimen for a Universeral Testing Machine. We got a good stress/strain curve on the wire without slippage. Most importantly, the wire broke at a location other than where the pawls had grabbed it.
