Abstract
A magnetic sensor actuation system is disclosed, which is suitable for use in a passive seat belt system of the type that a slide anchor with a webbing carried thereon travels along a guide rail having at least one bent section. The actuation system includes at least one magnetic sensor provided near the guide rail and a magnet provided on the slide anchor to actuate the magnetic sensor. Upon actuation of the magnetic sensor, the magnet is located on a line extending between the center of turning movement of the slide anchor along the bent section of the guide rail and the midpoint of an area of contact between the slide anchor and the guide rail.
