ABSTRACT:
A seatbelt webbing includes a shoulder part and a lap part. The shoulder part is a standard belt and at least part of the lap belt is an airbelt. In a front collision, a pretensioner of the shoulder part is activated, thereby retracting a specified length of the seatbelt webbing and tightening the shoulder part. As a result, part of the lap part slides through a hole of a seatbelt tongue toward the shoulder part, thereby correspondingly tightening the lap part. After a lapse of a predetermined period of time, an ignition control unit activates an inflator for the airbelt. Thus, the lap part is pulled and tightened by the inflation of the airbelt. Further, the inflation of the airbelt pulls part of the shoulder part through the hole of the tongue toward the lap part, thereby further tightening the shoulder part.
