Essentially these things are a variation on the inertia reel thats used in car seat belts. The inertia generated by the downward motion causes the part of the braking mech that is attached to the line drum against the stationary friction surface. Because of the nature of the two surface it creates friction that is enough to slow a descent but not stop it all together. Most also have a 'run-away' brake which is exactly the same as a car seat belt. In the event that too much momentum is gained the secondary mechanism will throw out a one way ratchet to arrest the fall.
