Abstract
Abstract A passive seat belt system is equipped with a guide rail, a slide anchor movable along the length of the guide rail and connected to one end of an occupant restraining webbing, and a drive means for causing the slide anchor to move along the length of the guide rail between an occupant restraining position and an occupant releasing position. Both end faces of the slide anchor as viewed in both running directions of the slide anchor flare out form the side of the webbing toward the side of the guide rail in the respective running directions.
