Abstract. Safety is an important concern in automobile design. In driving an automobile, acceleration and deceleration are realized by the driver’s leg and foot motion. If the shape of the instrument panel hinders the smooth motion of the knee, the operability of the automobile is significantly impaired. If the knee touches electric switches while driving, it may cause traffic accidents in the worst case. To prevent such problems, the United Nations (UN) defines a safety regulation based on the possible collision between the knee and the instrument panel. In CAD models of the automobile design, the instrument panel is positioned so that it faces the positive direction of the x-axis, and an apparatus imitating the knee shape during driving is defined.
