Abstract
Abstract The present invention relates to an automatically fastening seatbelt system wherein webbings for restraining an occupant are automatically fastened about the occupant upon his entering the vehicle, to thereby improve the safety of the occupant. This seatbelt system is of an arrangement that, when the occupant enters or leaves the vehicle, an webbing is positioned forward in looking from the vehicle to prevent the webbing to slide on the lap of the occupant and the like, so that the actions of the occupant entering or leaving the vehicle can be facilitated. This seatbelt system can drive a guide arm for moving the intermediate portion of the webbing and a sprocket wheel for moving an anchor of the webbing by use of a single motor.
