The invention relates to an interface device between a ski and element for retaining a boot on the ski. The device includes two stops intended to be connected to the ski toward the front and rear, respectively, of the central portion of the base of the ski, and a linking leg forming a stiffener between these two stops. The linking leg includes at least two levers, which are connected by at least one linkage forming a central pivotable connection. One of the bearing plates of the boot is vertically movable and transmits the vertical stresses from the boot to one of the levers, and an elastic restoring mechanism exerts an upward restoring force against one of the levers that is of sufficient intensity to keep the central pivotable connection of the two levers suspended when the boot is present. Preferably, the linkage between the levers is disengageable.

An interface device between an alpine ski and a ski boot for modifying the pressure distribution of the ski along a sliding surface of the ski, the ski being equipped with a front binding element and a rear binding element adapted to retain the boot in a central portion of the ski, each of the binding elements having a base plate connected to the ski and at least one bearing plate for supporting one end of a sole of the boot, said interface device comprising: a front stop and a rear stop adapted to be connected solidly to respective ends of the central portion of the ski; a linking leg forming a stiffener between said front stop and said rear stop; a front pivot connection between a front end of said linking leg said front stop and a rear pivot connection between a rear end of said linking leg and said rear stop, said front pivot connection and said rear pivot connection adapted to be raised with respect to an upper surface of the ski; said linking leg comprising at least a front lever and a rear lever raised with respect to the upper surface of the ski and at least one central pivot connection between said front lever and said rear lever for transmitting longitudinal forces between said front lever and said rear lever and for enabling movement of said linking leg between a raised position and a lowered position, said front lever and said rear lever being substantially longitudinally coextensive in said lowered position of said linking leg; and an elastic restoring device coupled to one of said front lever and rear lever for exerting an upward restoring force of sufficient intensity for maintaining said central pivot connection raised from the upper ski surface in said lowered position during application of a downward force exerted by the boot.
