Abstract
Force-indicating legs adapted to be fitted to the pelvic assembly of an anthropomorphic dummy for use in the dynamic testing of vehicle passenger restraint systems. The legs permit the measurement of most of the skeletal forces that are likely to be experienced during dummy leg contact with a vehicle instrument panel or a knee bolster in dynamic restraint system testing. Each dummy leg has a knee joint connecting the simulated femur and tibia bones and an ankle joint connecting the simulated tibia bone with a simulated foot structure. Forces acting on the simulated femur and tibia bones are measured by load cells capable of measuring axial (Z axis) compression and tension loads, shear loads on both orthogonal (X and Y) axes, lateral and longitudinal (or vertical) bending moments, and torsional moments. Knee shear load in the knee joint and upward angle bending load in the ankle joint are measured by load cells capable of measuring at least the axial loads resulting in the respective knee shear or ankle bending loads. The knee joint preferably includes biasing means to allow biomechanically correct tibia-to-femur movement during knee shear load measurements.
