  • Seat belt webbing energy management device
    Patent number: 5658012
    Abstract: A vehicle seat belt system (11) includes a length of belt webbing (60) for restraining a vehicle occupant. The belt webbing (60) has a shortened condition and an extended condition. An elongate tear strip (50), preferably made from seat belt webbing material, is connected between first and second sections (120, 122) of the belt webbing (60). The tear strip (50) is tearable lengthwise upon the application of a force greater than a predetermined force to the belt webbing (60) to enable the first and second sections (120, 122) of the belt webbing to separate and cause the seat belt webbing to extend from the shortened condition to the extended condition. The tear strip (50) tears over a period of time, reducing the abruptness of the load on the vehicle occupant during a vehicle collision.
