<p>A base member of a ski binding has vertical bores therethrough, and fastening screws which extend through the bores secure the ski binding to the top surface of a ski. Each bore has two vertically spaced, inwardly projecting shoulders which extend generally parallel to the top surface of the ski. Viewed from the top, each shoulder is delimited by two circles of different radius, the larger radius being equal to the radius of the bore. The two circles intersect tangentially at a point opposite the center of the shoulder, and the contact points of the circles of the respective shoulders are angularly offset by 180 DEG with respect to each other.</p> |
