Abstract: A knee joint for the leg of an anthropomorphic dummy of the type used in vehicle crash testing comprises a femur member including a disk portion with a widened rim and a central axial opening, a tibia member, at least one first joint member pivotably attached to the femur member adjacent the central axial opening and including a slide track thereon with a stop surface at the forward end thereof, friction surfaces on the first joint member and disk portion just outside the central axial opening, adjustment apparatus extending through the central axial opening effective to adjust the axial force and thus the friction force between the friction surfaces, at least one second joint member fixed to the tibia member slidably attached to the slide track of the first joint member for sliding movement toward and away from the stop surface in a direction substantially perpendicular to the tibia member and at least one resilient member disposed between the first and second joint member and having a pair of opposing surfa
