10210AEV2 REV. A <br />SECTION 2 Continued <br />The anchorages for the shoulder belt portion of a Type 2 belt assembly <br />shall be within the acceptable range when the seat is in its full REARWARD <br />and DOWNWARD position and the seat back is in it most upright position. <br />The acceptable range is referenced to the two-dimensional manikin <br />described in SAE J826 whose H-point is at the SRP and whose torso line is <br />at the same angle from the vertical as the seat back. When appropriate <br />information is available from the vehicle manufacturer, this range may be <br />determined by coordinate measurement. <br />2.4 ANCHORAGE STRENGTH <br />Type 2 seat belt systems (combination lap and shoulder) must be able to <br />withstand simultaneous loads of 3,000 pounds applied to the lap and <br />shoulder belts. The loads are applied in the direction in which the seat <br />faces, in a plane parallel to the longitudinal centerline of the test vehicle, <br />with an initial application angle of not less than 5° and not more than 15' <br />above the horizontal plane. <br />The rate of load application shall not be greater than 30,000 pounds per <br />second, and the 3,000 pounds of load must be attained in not more than 30 <br />seconds and held for a minimum of 10 seconds. <br />Type 1 (lap belt only) and the lap belt portion of a Type 2 system must be <br />able to withstand a load of 5,000 pounds applied in the direction in which <br />the seat faces, in a plane parallel to the longitudinal centerline of the test <br />vehicle. The initial load application angle shall be not less than 5 and not <br />more than 151 above the horizontal plane. The force must be applied with <br />an onset rate of not more than 50,000 pounds per second. The 5,000 <br />pounds of load must be attained in not more than 30 seconds and held for <br />a minimum of 10 seconds. <br />Permanent deformation or rupture of the seat belt anchorage or its <br />surrounding area is not considered a failure if the required force is <br />maintained for at least 10 seconds. Failure of a seat belt or its attachment <br />hardware before the required test load is attained is also not considered a <br />failure of the seat belt anchorage. <br />3 <br />
