Abstract: A bracket assembly device for seat belts comprising a bracket attachable to a vehicle wall by a mounting screw, the bracket comprising front and rear plates having holes for the mounting screw. The front plate forms a slip opening for the webbing or supports a member having such opening. The front plate is movable in essentially a vertical direction relative to the mounting screw and rear plate. The upper displacement position of the front plate is fixed by a member which yields when a predetermined downward directed force on the front plate is exceeded.
