A knee joint for an anthropomorphic dummy for use in motor vehicle crash testing comprises a femur member with a cylindrical pivot bearing, a tibia member with a cylindrical socket bearing having a radius greater than that of the pivot bearing, resilient locating strip between the pivot bearing and socket tending to restore the same to a substantially coaxial relationship and a plurality of pivotably linked arms defining a parallelogram having one side centrally pivotably mounted coaxially with the pivot bearing and the two opposite apexes pivotably connected to the tibia member. The arms allow rotation of the tibia with respect to the femur and further allow shearing translation therebetween only in a direction substantially perpendicular to the tibia member.
