Abstract
Breakaway web stops are provided which are employed in seat belt systems for restraining an occupant. In one such seat belt system, the seat belt webbing passes diagonally across the torso of the occupant, through a latch plate, and then across the lap of the occupant. To ensure that the latch plate stays in the correct position, web stops are placed on the seat belt webbing both above and below the correct position of the latch plate, allowing the latch plate to freely move between the two web stops, but not permitting it to move outside this range. In an accident, the breakaway web stop below the latch plate is configured to separate from the seat belt webbing, permitting the tension from the torso portion of the seat belt webbing to transfer to the lap portion of the seat belt webbing, providing additional and safety-enhancing restraint to the occupant, and, in particular, to the occupant's legs and lower body.
