Abstract
The inertia-actuated acceleration-sensing mechanism for an inertia reel for a vehicle safety belt comprises a pendulum that includes a circular plate that is mounted on a tubular support member for tilting movement at the edge of the plate. The mechanism also comprises an output member that is slidable on the tubular member in response to tilting of the plate, to provide a mechanical output of the mechanism. The tilting movement is arranged to take place about any position on a circle around a vertical line through the normal position of the center of gravity of the pendulum, the circle being centered on the vertical through the normal position of the center of gravity of the pendulum. When fitted to an inertia reel, the mechanical output of the mechanism is arranged to lock the reel against rotation.
