Abstract

A vehicle-occupant restraint system 20 in that gas of an inflator is introduced into a lap belt inflatable part from an end of the lap belt includes webbing 21 routed along the front of an occupant sitting on a seat 10, an inflatable lap bag 22 constituting the end portion of the lap belt of the webbing 21, the inflator 23 for inflating the lap bag 22, an anchor 24 for attaching the end of the lap bag 22 to a vehicle side member, and a retractor 25 for retracting the rear end of the webbing 21. The end of the lap bag 22 is attached, via the anchor 24, to a pedestal base 31 provided in a B pillar 30 serving as the vehicle side member. A protrusion 24e of the pedestal base 31 is inserted into a slot 31a, so that the swinging range of the anchor 24 is restricted.
