The belt force limiter is located inside the inertia reel on the belt housing and consists of a torsion bar. When a force exceeding a certain level acts on the belt strap, the torsion bar produces a controlled reduction in the locking effect of the inertia reel. In other words, it automatically limits the stress on the occupants chest in the case of sudden braking or a frontal collision.
