  • Patent number: 7789420
    Abstract: An occupant restraint apparatus includes a shoulder anchor and an occupant restraint belt. At least a portion of the occupant restraint belt that is positioned adjacent to the occupant's head is inflatable. The occupant restraint belt comes into contact with the top edge of the seat back even when the volume of the inflatable portion is reduced. A shoulder anchor is positioned behind a seat in the front-rear direction of a vehicle at substantially the same height or below the top edge of a seat back. Therefore, a shoulder belt section of an occupant restraint apparatus extending from the shoulder anchor along the front side of an occupant is in contact with the top edge of the seat back. Therefore, when the shoulder belt section is inflated, excess inflation of the shoulder belt section toward the seat back can be prevented.
