Patent ID: 6986526

Claim:
An arrangement comprising a ski binding and a ski boot adapted thereto with a boot sole, such that the arrangement includes: a first engagement element on the binding side, a second engagement element on the boot side in a front region thereof, wherein in a position for use the first and second elements are engaged with one another and keep the ski boot in substantial linear or areal contact with a ski or a binding plate attached to a ski, wherein at least one of an underside of the boot sole in a front region, and a sole-supporting surface on the ski or binding plate that is associated with the front sole region, is convexly curved in a long direction of the ski and boot, and wherein the first and second engagement elements are adapted to one another in such a way that when a back end of the boot is raised or lowered, with an accompanying, corresponding movement of the first and second engagement elements, the boot sole makes a rolling motion associated with a longitudinal shift of a contact line or area on the ski or binding plate and with a movement of the front end of the boot in the direction opposite to that of the movement of the back end; a third, boot-side engagement element in a middle region of the front part of the sole adjacent a region between the ball of the foot and base of the toes, and in a corresponding position on the ski binding a fourth, binding-side engagement element that engages the third engagement element so that the third and fourth engagement elements limit the extent to which the ski boot can be displaced backward with respect to the ski or binding plate and wherein at least one of the second and third engagement elements on the boot sole is constructed as an axle that extends generally transverse to the long axis of the ski, wherein the fourth engagement element comprises a stopping hook that can be swivelled about an axle extending approximately parallel to the upper ski surface or boot sole and transverse to the long direction of ski or boot, by means of which the third, sole-side engagement element, if it has been displaced backward, can be pulled in the forward direction, so that the boot is kept in position on the binding by the combined action of the first and second engagement elements which cooperate to limit movement of the boot in the forward direction, as well as the third and fourth engagement elements, which cooperate to limit movement of the boot in the backward direction.
