Abstract: The invention relates to an arrangement for changing the hardness, elasticity or rigidity of a sliding device for snow, which sliding device has a level of convexity which is predetermined during manufacture, having a stiffening device which can be fitted on the sliding device and can be changed, in terms of its action on the sliding device, by a control mechanism. The aim of the invention is, by changing the level of convexity, to be able to adapt the travelling properties of the sliding device to the respective skiing/snowboarding conditions in a particularly effective manner.

In order to cause in this front jaw during a backward twisting fall an initial tension of the release spring and thus a reduction in the work of the swinging-out toggle lever, the invention provides that the two shorter lever arms of the toggle levers are loaded by a release spring acting through a pull rod onto an angular intermediate lever supported in the lower area of the housing on a first pivot axle.

Abstract: A ski (1) which consists of a core (2), at least one upper surface layer and one lower surface layer. Recesses (6) are provided in the binding area, in which recesses containers (8) are fixed. Inserts to anchor fastening screws are inserted into the containers. Each insert consists of a layer of an elastomer material and of a layer of a fixed material, for example metal or glassfiber-reinforced plastic. In order to avoid in this ski (1) a drilling through the layer (10) of elastomer material and in order to also be able to stress this layer (10) with respect to tension and compression, the invention provides that this layer (10) is below the layer (9) of solid material and is fixedly connected both to the bottom wall (8a) of the container (8) and also to the layer (9) of solid material.

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.

The base plate is held onto the upper side of a ski by means of fastening screws, and is held against a lifting off in its mounted state and is also secured against a movement relative to the ski by means of a locking system. A block is formed by the fastening screw and engages a detent formed in a recess in the sole-support plate to prevent the aforesaid relative movement.

Abstract: A toe unit for a safety ski binding for disposal on a horizontal surface of a ski includes a base adapted to be mounted on the ski, a bolt having a lower end and an upper end, and a mounting portion for mounting the lower end of the bolt to the base. The mounting portion permits axial movement of the bolt between a first position and a second position, and secures the bolt substantially perpendicular to the horizontal surface of the ski when the bolt is in the first position. The mounting portion also permits pivotal movement of the bolt about a location on the base when the bolt is in the second position. The toe unit also includes a sole contact portion attached to the bolt for retaining a sole of a boot and for moving the bolt axially from the first position to the second position in response to a predetermined force exerted by the boot in a direction away from the base.
