Abstract: A sole-support device for ski bindings which includes a support member fastenable on a ski and an endless band guided transversely with respect to the longitudinal direction of the ski in a groove of the support member. In order to prevent in this device a relative movement between the upper strand of the band and the underside of the sole of the boot, the invention provides that the band, which is supported with its upper strand in the groove of the support member, has the shape of the jacket of a frustrum, and that the groove, in which the upper strand of the band is guided, has a circular extent arched toward the tip of the ski, viewed in a top view.

Abstract: A sole-support device consisting of a support member and a continuous or endless band guided transversely with respect to the longitudinal direction of the ski on the support member. In order to guarantee in such a device that a secure support of the sole of the boot on the band occurs and in order to avoid friction between the sole of the boot and the support member, the band is supported with its upper reach in a groove of the support member, the upper side of a front section of the band lying in a plane that is higher than a horizontal plane of a boundary edge of the front wall of the groove, the upper side of a rear section of the band being aligned with an upper boundary edge of a rear wall of the groove or in a horizontal plane which lies lower than the boundary edge.
