Effect of load limiting the shoulder-belt on right-front passenger kinematics in oblique-offset and NCAP frontal crash tests

Excursion of the upper torso with the load-limiting shoulder belt enabled the belt to slip off the right shoulder in ODMB tests. The passenger flexed forward around the lap belt with impact on the center of the instrument panel. The upper torso lacked sufficient restraint with the level of load limiting in the tests. The belts were loose after pretensioning and load-limiting reducing the restraint effectiveness if there were a second or third impact or rollover in the collision sequence.
