    Abstract: A knee protector is used in an automotive vehicle equipped with an instrument panel and a steering column which detaches from a mounting portion so as to absorb energy applied to a steering wheel connected to the steering column. The knee protector is arranged within the instrument panel at a location neighboring the steering column and is fixed to the instrument panel. The knee protector has a pair of ribs which extend in a direction essentially perpendicular to the axis of the steering column. The ribs project from one surface of the knee protector and are recessed in the other surface thereof. The ribs serve to reinforce the knee protector and to make deformation of the knee protector easy when a load is applied to the steering wheel in the direction of the axis of the steering column. The knee protector is made of a material which is deformed to absorb impact energy when impact force is applied to the knee protector body.
