Abstract

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